This prior work is dissimilar to the present invention, having no common features.
- This prior work employs vacuum, instead of positive pressure, for irrigating wound area and comprises a spray nozzle for delivery of liquid under high pressure, an irrigation tube, a suction trap and a portable suction unit for the working of the device.
- the present invention has no features found in this prior work.
- This prior work for medical irrigation, comprises a plurality of flexible reservoirs containing liquids to be sprayed on predetermined area, a pair of air bladders and a pair of pressure dump valves.
- the device of this prior work is different from the present invention, employing a peristaltic pump and a plurality of pressure spray nozzles.
- Disasters such as earthquake, bomb blast and railway accidents entail speedy first aid treatment to mass victims, before they are transferred to hospitals. A large number of victims need their wounds to be properly cleaned with antiseptic solutions before dressing.
- the starting point of first-aid is washing wound. If the wound is washed properly the infection can be controlled. Manually washing of the wound is time consuming and requires a large number of trained personnel, who may not be available at the place of accidents. To address this issue, the wound washing apparatus is developed.
- the present invention is designed to handle a large number of persons within a short period so that wounds and burn injuries of mass victims can be effectively cleaned and disinfected.
- Another object of the present invention is to provide ease in assembling and dissembling the apparatus. Another object of the present invention is to deliver consistent operation in terms of cone angle of spray, droplets size, volume of liquid pumped irrespective of level of liquid in the tank.
- Silicone tubing which is used as a part of the jetspray apparatus, is sterilizable.
- the peristaltic pump can be operated for achieving greater discharge of disinfectant solution.
- the major advantage of using a peristaltic pump is its non-contact method of pumping.
- the disinfectant solution does not come in contact with rollers of the pump, thereby eliminating contamination of the solution being pumped.
- Peristaltic pump has less moving parts thereby, drastically reducing breakdown.
- Drawing # 1 illustrates schematic arrangement of jetspray wound washing apparatus (100).
- Drawing # 2 illustrates silicon tube (60), traversing a path of inverted hyperbola around eccentric cam (36) of peristaltic pump (30).
- Drawing # 3 illustrates front sectional view of 5-litres capacity stainless steel 316-L tank (10) and accessories thereof.

- Drawing # 10 illustrates 12 volts battery (40) and its circuit (41).
- Spray automization covers large area and enters all corners of wound thereby leaving no part of the wound remaining unwashed. While victims are carried on stretcher, wound- washing activities could be performed minimizing time delay. Without moving victim, cleaning of the wound can be achieved by using spray nozzles. Evaporation of fine droplets depends upon exposed surface area. The droplets coming out of nozzle are controlled in such a fashion that a part evaporated creates sterile environment around the affected area and remaining droplets cleanse the wound. While the droplets evaporate, they take out the heat from surrounding atmosphere thereby causing cooling effect that reduces burning sensation to victims.
- the container which encloses the jetspray apparatus (100), is made up of unbreakable plastic ergonomically designed to ease carrying.
- the container is provided with back carrying arrangement due to which both hands of the operator are free to engage in effective cleaning of wound.
- the container has a place to store the following accessories: gloves
- the battery (40) and its electrical circuit (41) provide 5 hours of continuous operation with deep discharge characteristic.
- the battery (40) is sealed lead acid type and maintenance free.
- All tube fittings are safe push fittings. While in operation, should a fitting come out loose for any reason, the flow of liquid gets stopped.
- the peristaltic pump (30) allows for step less increasing and decreasing of the speed because of which the discharge become adjustable to take care of the distance.
- Minimum pressure required to clean wound without pain varies from 8-12 psig and safety valve is set at 15 psig pressure.
- the wound irrigation is divided into high pressure irrigation where the pressure maintained is 8 - 12 psig and low pressure irrigation where pressure is maintained between 5 - 6 psig.
