3. Introduction Warm fluid is used for irrigation to prevent body heat loss/hypothermia if used in large amount and to prevent vasoconstriction in microvascular surgery.

4. How It’s Done Now? Hot solution is stored in a hot press prior to use. This will produced a hot solution – which normally needed to be mixed with regular (unheated) solution to get the desire temperature.

5. How It’s Done Now? The solution is filled into the syringe and flushes onto the desired area. When the solution is cold, part of the solution is discarded and warmed solution is added to the desirable temperature.

6. Disadvantages Not cost effective. –Waste of solution Labour intensive Potential delay

7. Intra-Operative fluid warmer device. Main Objective: To develop a cheap, user friendly and effective fluid warming device to be used intra-operatively Featured with:- Temperature regulator controller to keep the irrigation fluid warm during operative procedure.

8. Why Do We Need This Device? To provide a constant supply of warm solution intra-operatively at desired temperature. Prevent waste and cutting the cost. Prevent delay and save time.

9. Features of Negative Pressure Regulator Required. 1.Cheap 2.Small/light 3.Portable and washable with heat resistant detachable component for autoclave (sterilisation) 4.Has automated temperature regulator with digital temperature indicator to prevent excessive heat and burn injury to patient and staff.

10. Suggested design 1 Three separate components 1.Main unit - Heat generator with temperature regulator. 2.Silicone tubing. 3.Stainless steel pipe coiling - for heat transfer and maintenance.

11. Suggested design 1

12. Main unit to heat up liquid to a set temperature with a pump to circulate the heated fluid through the tubing to the coiling which can be placed outside/inside a pot, or can be placed inside a kidney dish.

13. Suggested design 2 2 separate parts;- 1) detachable hot elements with termostat/temperature reader 2) power supply with temperature regulator ranging between 28-36 degree Celcius

14. Suggested design 2

15. The benefit of this project 1.To produce a new easy to use fluid warmer device for intra-operative usage. 2.Safe cost and minimising waste. 3.New product invention by the university. 4.The product will be highly value in hospital set up and has potential for world wide marketing
