Kickoff Meeting - 9/27/2011

Tonight we had our first official meeting for the new semester. Jack, Mike, Oliver, and Bilal joined us for the first time. Members present: Steve, Dan, and Elliot.

Here's an outline of the meeting:

I. Introduction: Gave prospective members an overview of the project and where we're headed during a Q&A session.

II. Short-term goals for this semester
  • Redesign lamp head: new LEDs, focusing, etc. Jack's Engin 100 group might take on the project
  • More stable base
  • Circuitry
  • Find LEDs with narrower beam angle: Mike knows where to get them
  • Portability & Modular design
  • Recruit faculty advisor specifically for the Life Lamp Team
  • Modify previous grant proposals: We should look into working with Centricycle Team for some insight since they have some experience
III. Trip Opportunities
  • World Medical Relief (WMR): Those that are interested may travel abroad with WMR with the surgical lamp. It will most likely be Philippines, but we need to contact WMR for more info.
  • Nicaragua: Next Summer - We could collaborate again with the Maternal Health Team.
IV. Meeting time: Our regular meeting time will be Tuesdays at 7 PM @ LBME for this semester.

V. Next week: We will start working on a new prototype.

2011 Nicaragua Trip Update

This is what the lamp looked like right before the trip.




 Here's a brief summary of the trip to Nicaragua (Summer 2011).

1. District Hospital of Esteli, Nicaragua: We assembled the lamp in front of the technicians and officials of the hospital. Once the lamp was put together, we demonstrated its use and various features. In general, the lamp was well-received and people were highly interested. They even took pictures of the lamp!



  • Is there a need for improved surgical lamps? Yes. More efficient lamps are needed (v.s. conventional incandescent lamps).
  • Is need constant or sporadic? The lamp we have here works well sometimes, but is intermittent. Bulbs don’t last long (200-300 hrs) from the overhead source. We tried to extend life by adding protection/insulation. We have electrical energy but quality of the lamp is a problem. Power also gets interrupted, and we tried to fix fluctuations from power surges. For example, this morning, we lost power for three hours (happens about once a month), but we do have two back-up electrical generators (can support everything but X-ray) that can each supply 72 hours worth of power. 
  • Hospital does not have any type of mobile solar systems, but that could be potentially helpful in different areas. 
  • Hospital's top priorities for a surgical light source: white light, cool, low energy.
  • They really liked the ~12 in. diameter spot and how we worked on shadow control.
  • Ideal/desired battery life is ~12 hrs.
  • They liked how we used PVC to narrow beam angle.
  • They suggested the wooden base made of something else. Keep it light, but some weight would be good for balance and stability.
  • They suggested lamp head open like an umbrella mechanism to adjust focus...however, the current setup is good enough for minor surgeries.
  • Make it consistent with different assembly tools (for instance, be able to assemble the lamp with 2-3 different tools).
  • Most complicated issue for the hospital is to buy and attach LEDs, otherwise the lamp can be built there.
 

2. Sacuanjoche Clinic in Matagalpa, Nicaragua: We visited a small private clinic that visits isolated rural villages routinely to provide health services. We also traveled to one of the villages, Santa Ana, with the clinic. During the visit, we experienced a power outtage that delayed medical exams. See where the lamp comes in? Here are some of the feedbacks:


  • Change wood base...perhaps to a tripod base.
  • Be able to focus the light.
  • Adjustable (extendable) arm.
  • All parts are readily available in Nicaragua says Dr. Armando (head of the clinic).
  • Increased portability: this was the clinic's particular interest since they frequently visit rural villages with their medical equipments.

8. How often does the power go out for? For how long?
9. What are the most common procedures requiring surgical lamps? Where are they performed?
10. Do you see the lamp being used for anything other than surgery?
11. What is currently being used for surgical lighting? What about during blackouts? How well does this work?
12. Do you think a grid-independent surgical lamp would be a cost-effective way to improve the quality of care?
13. How important is portability for surgical lighting?
14. Are you interested in helped us to design/implement a surgical lamp?
15. What other equipment/supplies are needed for surgical lamps to be useful? Anesthesia? Disposables?
16. Do you have any questions or comments? Are there any questions that you think we should have asked that we didn’t?

Some Lit Search Findings

I worked on a lit search regarding the availability and quality of surgical lighting, and while I didn't find any studies explicitly reporting the information we were looking for, I did find some interesting papers. I'm including the name and some of the important information from them; they're all available from google scholar or through the university.

Quantifying Surgical and Anesthetic Availability at Primary Health Facilities in Mongolia
David A. Spiegel • Shelly Choo • Meena Cherian •Sergelen Orgoi • Beat Kehrer • Raymond R. Price •Salik Govind

Not much info, but in the table towards end 11% reported to have access to lighting, eg flashlight, surgical, etc

A protocol for safe anasthesia for cleft lip and palate surgery in developing countries
S. C. Hodges, A. M. Hodges

"The majority of hospitals in Uganda are severely underfunded and understaffed. Reliable electricity is unusual. In some centres there is no running water and the majority of hospitals have no oxygen. Many of the operating theatres are small and cramped with poor lighting and no recovery room"

Quantifying surgical capacity in Sierra Leone: a guide for improving surgical care
T. Peter Kingham, MD; Thaim B. Kamara, MD; Meena N. Cherian, MD; Richard A. Gosselin, MD; Meghan Simkins, BA; Chris Meissner, BA; Lynda Foray-Rahall, MD; Kisito S. Daoh, MD; Soccoh A. Kabia, MD; Adam L. Kushner, MD, MPH

-info on availibility and periodicity of electricity

-"Even when electricity was available, lighting was
a problem, given there were approximately 6 individual lightbulbs that worked in all of the dome lights throughout Sierra Leone. Most operating rooms subsisted with a portable light or sunlight."

-hospitals in the capital have been receiving electrical power at an increasingly steady rate

-"The 5 other hospitals surveyed depended on generator power, but owing to the scarcity and cost of fuel, patients’ families were sometimes required to provide the necessary fuel to power generators during surgical procedures."

-"In addition, basic infrastructure, such as lighting in the operating room, is an example of a small investment that can have an enormous effect. The lightbulbs required in Sierra Leone, for example, were found to cost less than US $0.50 at a factory in China."

Lamp Head/Thesis Review

Hey guys,

Below is a picture of our next-prototype lamp head, in case you didn't get a chance to see it:


Also, I looked over Abigail's thesis for background information and this is what I found:

She visited 3 regional hospitals and ten health clinics in Ghana/Uganda, and from these trips claims that "due to the unreliability of electrical energy there have been cases of deaths in surgery and delivery wards.” She then shares several anecdotes concerning complications caused by surgical lighting failure during power outages, but has no numbers or data to show how often this is actually happening.

She also claims that the electrification rate (percent of population that has electricity) in Uganda is 10%, and states that this is similar to most low HDI countries, where electrification rates range from 2-50%, with reliability at or below 50%.

This graph below was also contained in her thesis. I am unsure of its source, but it shows how often power outages occur in Uganda, and could definitely be helpful when we are looking for more quantitative data to prove our cause.

Lamp Update 3/15

Hey guys,
First Jack and Melissa gave some quick updates on research they've found relating to surgical lighting in developing countries. This info should be up on the blog soon. Next, we a look at the light the lamp head puts out. From a completely unprofessional viewpoint it seems to be bright enough and was able to (dimly) light up an entire LBME classroom. Next, Elliot and Mike went to the Wilson Center to attach the lamp head to the lamp frame with a pair of L-brackets. The process ended up being more difficult than anticipated, so we'll finish that up next week. Liz, Melissa, and I made a list of new survey questions (included at the bottom of this email) which have been sent to the survey team. Next, we talked about the poster and changed the categories to Background, Lamp Design, Implementation, and Future Work.

Registration for the global health symposium is due on Monday, March 21st, don't forget to register if you plan on going.

Tasks for the Week:
Steve: Find out when M-HEAL is going to WMR next, write the Future Work part of the poster
Melissa: Post lamp need info, write the Implementation part of the poster, talk to Mike Lee about when Wilson Center trainings will be
Liz: Write Lamp Design part of the poster
Jack: Post lamp need info, write the Background part of the poster
Elliot: Compile the poster over the weekend
Pat: Write the abstract for the poster
Mike: Begin work on a CAD drawing of the lamp

Please send your portion of the poster to Elliot by 7pm on Friday. Elliot, send the compiled poster to the group by Sunday at 7pm for feedback.

Let me know if you have any comments or questions or if I forgot to include something.

Best,
Steve

----------------------------------------------------------

Ugandan Technical Schools/ Lamp pictures


Below are links to two different directories of Ugandan technical schools that I found when we were talking about possible schools to approach last meeting. They are both basically online collections of information about technical school in Uganda, including names, locations, and contact information. If we decide we want to go ahead and speak directly to schools, this would be a great resource to find potential schools to contact.



I also went in to LBME today and took a bunch of pictures of the lamp to be used in our flyer. Below are a few of the better shots, but if you want a copy of all of them, email me and I will send them to you!

2/15/2011 Meeting Summary

Here's the lamp update for the week:

I. This Week's Meeting:
Yesterday we discussed our plan of action for finding a partner organization. We will update our brochure and then talk to Moses Lee for feedback on our brochure and pitch. After meeting with Moses we'll start contacting NGOs and trade schools. Our current model is to partner with trade schools and have them incorporate lamp building into their curriculum. This provides them with some additional revenue for the school and solves the sparse need problem. We found that there is a good directory of trade schools in Uganda. Pat and Liz worked on the generator and found that it generates slightly more power than expected. Liz updated us on her meeting with the EECS prof (details on the blog).

As a result of feedback during the general body meeting, we are going to try to build our lamp frame out of a single bike.

The main things that need to be fixed in the brochure are:
- mention more than just Africa as our target
- talk about technical school partnerships
- change hand-crank generator to bicycle generator

II. Action Items:
Melissa: Take pictures of the lamp with a mock head and counterweight; post Ugandan technical school directory to the blog
Mike D: Read the relevant sections of Abigail's thesis and post a summary to the blog (include technical info, location info, partner info, etc)
Dan: Update the brochure
Steve: Set up a meeting with Moses Lee
Pat: Do generator calculations
Liz: Talk to BlueLab about their bike generator
Jack: Calculate the specs we want for LEDs and look for some matching ones online

III. Abigail's Thesis:
Here's a link to Abigail's thesis: http://mirlyn.lib.umich.edu/Record/007294554.

Also, here's a link to her website (which has some relevant stuff): http://www.empowerdesign.com/

IV. Next Week:
Next week we'll be meeting at 8pm in the LBME project room. Some of the time will probably be spent in the Wilson Center putting together lamp heads.

Meeting with Professor Hofmann

Hey everyone,

Some ideas for editing our current generator:
  • Using a hallow core rather than solid steel
  • Moving the core closer to the magnets
  • Rearranging the magnet orientation so that as a south pole passes one end of the core, a north pole passes the other end. (1st diagram)
  • Eliminating a core and changing the orientation of the wire (2nd diagram) spiraling the wire vertical rather than horizontally. However if more than one coil is used, such as in the 2nd diagram (a coil is represented by the red spirals), the direction of winding the coil must be alternated.















For the shake light idea this was the general design the professor advised...

This is a DC device, so it wouldn't need to be rectified like the bicycle design.

I also estimated the number of coils used on the current generator to be about 3132. The current wire is also 26 mm gauge magnet wire.

Notes from the 2/8 meeting

Business:
goal price under $100
want idea of battery life
target brightness around 800 lumens

Lamp Head:
real surgical lamps are ~2,600 lumens - ours doesn't need to be so bright
we should try to get our head to be big - close to 20" to reduce shadows
need LEDs with smaller beam angle although we can use these for an initial prototype
should try bike rim, pot, and fan cage

Generator:
Waveform looks decent
lots of noise
connections need to be tightened up

Next week:
start working on three heads
put new rectifier on he generator
glue magnets on the generator
maybe make the generator stand stronger

Action Items:
Dan: call dad about surgical light, look for NGOs
Jack: look for NGOs
Pat: get a fan cage and a pot
Melissa: look up cellphone battery life (for at least a couple different models of phone), talk to Mike Lee about training
Elliot: post article online, take pictures of the current lamp prototype for the general body meeting
Mike: Get an estimate of the power one can generate from the foot pump generator
Steve: work on ppt for the general body meeting next week, get former MBA team members in touch with Dan
Liz: Get developing country bike statistics (cost, availability, etc)

Possible Non-Profits

Here are some nonprofits that are possibilities for getting in contact with. I tried to look for ones with characteristics that we talked about in the meeting. I'm including a brief summary along with links to each of these pages, if people want to look at it and give some input.

International Medical Corps:
http://www.internationalmedicalcorps.org/Page.aspx?pid=183

-Work in Africa, Middle East, and Asia
-Focus on community-based health care
-Emphasize training and education in both medical and non-medical fields
-Recruit most (96%) of their staff from the local community

MAP International
http://www.map.org/

-Christian organization working in Africa, Latin America, and Asia
-Provide medicine and disaster relief
-"seek to promote the Total Health of the communities we serve through the identification, training, equipping, and supporting of community leaders"

PCI
http://www.projectconcern.org/

-Work in Latin America, Asia, and Africa
-Active in HIV/AIDS and infectious disease prevention and treatment, but also emphasize economic empowerment and community based health care

Project CURE
http://www.projectcure.org/

-Medical supply and equipment distributor
-Very widespread distribution route

SHARE Africa
http://shareafrica.org/

-"Foster and promote health care education, research, advances in the health field, and the growth and availability of quality healthcare services"
-"Coordinate and support activities of not-for-profit organizations engaged in the betterment of mankind"
-Focus on sustainable projects based on community involvement
-Ship and distribute medical supplies as well

Most of the groups that I linked here are ones that have a focus on creating jobs within the local community. There are quite a few nonprofits out there that are focused more on medical equipment and supply shipment and distribution, but I thought that the ones I included here may be more specific to what we were looking for. These are just ones that I've found and I think are worth looking into, so if anyone has any more to add, please do so

Conventional Surgical Lamp Specs

Here's the link to the Steris article I was talking about:

http://www.steris.com/media/PDF/support/education/StudyGuides/M1722%20Lighting%20the%20Way%20to%20Surgery%20SG%203%207-10.pdf


Some of the key specs:

- Surgical luminaire should produce between 40,000 and 160,000 lux
- Pattern size should be a min diameter of 6" to a max diameter of 12"
- Luminaires with diameters greater than 20" offer best shadow control
- Intended working distance (focal length): 39" (100% luminance)
- Desirable working range: 30" - 50"
- Close distance where illuminance is 20%: 24"
- Far distance where illuminance is 20%: 60"
- Depth of field: 36" (distance from 24" to 60")


Some pictures I found online that might give us an idea...

Meeting with Professor Hofmann

Hey everyone,

Sorry I didn't make it to the last meeting. So I emailed the professor and I scheduled a meeting with him for this Thursday at 11:30, his office is in the EECS building. I will post his office number as soon as I find out. Sorry for the inconvenience and late notice. I'd appreciate anybody who can come :) But if not I totally understand.

Thanks,
Liz

2/3 Lamp Update

Hi everybody,
Here's this week's lamp update:

I. Meeting Summary:
Today Mike Dicenso joined us for the first time and told us about his idea to use a "shake light" type generator for the lamp powered by a foot pump. The engin 100 team actually initially wanted to have a foot pump design, but ended up going with the pedal design due to time constraints. This has the advantages that it probably would be easier to build than the pedal generator and could more easily be located in the operating room if the battery was running low during a surgery. The overall efficiency of this method and how well it scales up are unknown. We will be contacting an EECS prof. who is an expert on generators (and is currently teaching a generator class) to hear his advice. We also tested one of the LEDs that we got from ATC. Mike and Elliot's star-filled vision can testify to how bright they are. We just hooked it up to one of the power supplies in the project room. The LED has an angle of about 100 degrees so the spot size is much bigger than the 6" at 36" that we're looking for, but judging by how bright it is, 8 of them seem like they should be bright enough. If we do want to shrink the spot size, we'll have to design some kind of reflector assembly.

II. Action Items:
Elliot: Find FDA surgical lamp specs
Liz: Find out when the EECS prof is available and set up a meeting time
Mike D.: Post sketches of the shake light generator to the blog
Dan: Read over the material I sent you
Steve: Figure out what funding we have this semester

III. Next Week:
Our next meeting will be at our normal time, Tuesday at 8pm in the LBME project room (right after the M-HEAL general body meeting). First we'll start with a discussion of where we want the lamp to go from an implementation/business perspective. Then we'll break off into two groups with one group checking out the waveforms from the current generator prototype and one group starting to build a prototype lamp head with the new LEDs.

IV. Stuff Coming Up:
The lamp team will be presenting at the M-HEAL general body meeting two meetings from now. Development day is a day-long event where project teams set aside the day for M-HEAL in order to get a ton of work done. We keep you well fed, it's a good way to get to know other people in M-HEAL, and all the teams get a chance to get feedback from other M-HEAL members. Development day is scheduled for March 12th, so mark your calendars now. It will probably run from 10am to 7pm. The NCIIA grant proposal is due on May 6th. We've been competitive for this $20,000 grant in the past and have been told that with a more detailed business plan we should win it.

V. Brightness Units:
As per usual, we got tripped up by the proper units for describing how bright something is. Here's two wikipedia pages explaining how the units work.
http://en.wikipedia.org/wiki/Photometry_(optics)
http://en.wikipedia.org/wiki/Radiometry

Don't forget to post the work from your action item on the blog. If you have any questions shoot me an email.

Generator Report

Below is the executive summary from our final report for the generator. I am unsure on how to attach the entire report, which including the appendices and table of contents is about 45 pages long. I have it in both Microsoft word and pdf format. If anyone knows how to upload a pdf or word document please let me know. I can also email it to people individually.

-Liz

The purpose of this report is to present our findings regarding our manually powered generator design for charging cellphone batteries to M-Heal, the student organization we collaborated with. This report presents our prototype design and prototype tests. Because our prototype design did not generate enough electricity to charge the cellphone batteries, our report also discusses changes that should be made to our generator design in order to successfully charge cellphone batteries.

M-Heal had previously designed a surgical lamp which operated using cellphone batteries in order to provide reliable lighting in Ugandan operating rooms. Currently, the cellphone batteries must be charged using electricity from a power grid; unfortunately, Uganda’s power grids are unreliable. Consequently, a surgeon can be left without lighting during surgery.

Our solution was to design a manually powered generator that could charge the ten cellphone batteries. As part of our task, we followed the criteria established by M-Heal as well as criteria we devised after considering the problem. These criteria included using sustainable parts, ease of construction, and ease of operation.

The main parts of our generator prototype were obtained from used automobiles, cellphones, and bicycles. Our research indicated that these used devices are available in Uganda and allow our design to be constructed and maintained in Uganda. Our prototype design consisted of three main components, the generator, the circuit system, and the stand. The circuit system contained two circuits; the first circuit used the energy our generator produced to charge a car battery and the second circuit charged the cellphone battery using the stored electricity in the car battery.

Prototype testing revealed that the amount of electricity we generated was insufficient to charge the cellphone batteries. From the results of our voltage test, we concluded that the voltage that our prototype produced was too low to charge the car battery. Because we could not charge the car battery, we were unable to charge the cellphone batteries.

Based on our research and tests, we have devised several design improvements. These recommendations are mainly concerned with the electricity output of our generator. We propose to optimize the AC voltage produced by our generator by adding more magnets to the wheel, moving the steel core closer to the bicycle wheel, and adding more wire coils to the core. In order to prevent the high voltage losses after rectification, we also suggest using a more efficient rectifier.

While we did not meet our criteria of charging ten cellphone batteries, we did create a working generator out of parts which are sustainable materials in Uganda. We recommend that a future team continues our work and improves the design of our generator in order to successfully charge the cellphone batteries.

Meeting Summary 1/24

Hi everybody,
Today's lamp meeting was just a overview of the project for our new team members and some general brainstorming. The major goals of this semester will be to build a new lamp head, build a new generator prototype, and create a more specific business plan. We need to have the next prototype ready to send with the Nicaragua team for their trip in June.

Action Items:
Liz: Post a summary of the engin 100 generator project on the blog
Melissa: Learn about the physics of generators
Pat: Think of reasons why the current generator prototype isn't very efficient
Elliot: Draw up two designs for the lamp head


The Lamp Team Blog:
Here's the url for the lamp team blog. If you have any interesting ideas or see any interesting articles please post on it. You should also post the results of whatever action items you're working on between meetings. The url for the blog is http://mheal-lamp.blogspot.com/.

Survey Team Lamp Results:
The results from the survey team's surveys are attached to the email I sent out today. If you haven't read them over yet I suggest doing so.

Next Week:
The next lamp team meeting will be on Tuesday directly after the M-HEAL general body meeting (so around 8pm), once again in the project room. We will look at the waveforms of the current generator and discuss improvements to the design. We will also discuss new head designs.
