2. Background
Ocular perfusion pumps have been implemented outside of the ICU and surgical settings in which self-lubrication or manual lubrication is not available or convenient.
Our pump is immobile and is to be used in the ICU or surgical setting to decrease the time nursing personnel would spend lubricating the eyes of patients who cannot perform this function on their own.

3. Personal Responsibilities
Components:
Fluid pump/ reservoir
Delivery Mechanism
Spray Mechanism

4. Spray mechanism Based on experiments done in Dr. Kameneva’s lab
There is a minimum of 8 ml/min flow rate needed to have the mechanism spray
This equates to a mmHg pressure.

5. Delivery mechanism
Using Hagen Poiseuille determined the inner diameter of the sprayer was 0.06 inches
The diameter needed of the delivery mechanism, silicone tubing, is being calculated based on the height needed to maintain the 60 mmHg pressure and the varying widths possible.

6. Fluid pump
Because the 8 ml/min flow rate is much higher than the amount of fluid we are going to be spraying, and is too small for any researched fluid pumps on the market for based on the 0.06 in. diameter
Based on experimentation with the spray mechanism, and silicone tubing with an inner diameter of 3/8 in, done in Dr. Shroff’s lab, we concluded that gravity was enough to maintain the pressure needed and that we Do not need a fluid pump

7. Personal Accomplishments
Components:
Fluid pump/ reservoir : do not need, reservoir will be IV bag able to hold at least 50 mL
Delivery Mechanism: still experimenting on the relationship of size to height to maintain the 60 mmHg needed
Spray Mechanism: determined the characteristics of it; further experimentation on the size of the droplets and area of spray when the nosepiece is designed
