Description

Technical Field

[0001] The present invention relates to the technical field of on-site treatment, and particularly to a wound disinfection, irrigation and cooling device for on-site treatment and casualty transportation. Background Art

[0002] On-site treatment refers to the first-aid medical treatment before the emergency casualty (patient) is sent to a medical institution, generally referring to on-site or nearby treatment at the scene where the casualty is injured. In cases of firearm injuries, fractures, chemical agent contamination, burns, snake and insect bites, the wound is attached with harmful and toxic substances and is prone to infection and tissue degeneration and necrosis. If wound disinfection, irrigation and cooling can be implemented, the wound surface can be effectively protected, the development of the injury can be slowed down, the inflammatory reaction can be reduced, bleeding can be reduced, tissue swelling can be reduced, and organ tissue damage can be reduced, which can greatly improve the treatment effect. If disinfection, irrigation and cooling cannot be carried out, the injury may develop into a critical condition, and even disability and death may result.

[0003] However, due to the limitations of the treatment environment and the equipment carried, it is currently inconvenient to disinfect, irrigate and cool the wound during on-site treatment and casualty transportation. The main reason is that due to the limitations of off-site treatment conditions, there is currently a lack of portable and easy-to-operate first-aid equipment for completing wound disinfection, irrigation and cooling. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the present invention provides a wound disinfection, irrigation and cooling device for on-site treatment and casualty transportation, which can achieve preliminary disinfection, irrigation and rapid cooling of the wound, can effectively protect the wound surface, slow down the development of the injury, reduce the inflammatory reaction, reduce soft tissue swelling, reduce organ tissue damage, and at the same time, the low-temperature state can reduce bleeding and reduce cell damage. The disinfection, irrigation and cooling functions of the device can also perform first-aid treatment on different injury sites, and are applicable to a wide range of injuries. The device has a reasonable structural design, is convenient to carry, and has practical functions, and is suitable for on-site treatment and carrying.

[0010] Further, the housing and the movable base of the controllable valve are thread - connected, and a pull - ring is installed on the limit pin. When the limit pin is installed, the front end of the movable base cannot puncture the sterile puncture membrane. After pulling out the limit pin and rotating it forward 1 - 2 turns, the sterile puncture membrane can be punctured;

[0011] The sterile puncture membrane is a plastic sealing membrane or a sticker puncture membrane.

[0012] Further, the shape of the third bag body can be square or flat tubular. The cooling particle channel and the distilled water channel of the third bag body are sealed by a rubber stopper, and the distilled water channel cannot be squeezed to open the rubber stopper without opening the controllable valve on the pipeline.

[0041] When the wound disinfection, irrigation and cooling device for on-site treatment and casualty transportation of the present invention is used, the corresponding controllable valve is opened. The opening method of the controllable valve is to pull out the limit pin through the pull ring on the limit pin. After pulling out, rotate the movable base forward 1 - 2 turns so that the puncture end pierces the sterile puncture membrane to make the first and second bag bodies communicate with the third bag body. When the sterile puncture membrane adopts a shrinkable silicone puncture membrane, rotating the movable base in the reverse direction can close the controllable valve;

[0042] By squeezing the tubular water outlet, the liquid in the bag flows out. The head end of the columnar water outlet is provided with several micropores. The sealing cap is an elastic rubber sleeve. When the sealing cap is removed and the tubular water outlet is pinched, the water can flow out from this end for flushing the wound;

[0043] Normally, the first bag contains hydrogen peroxide, and the second bag contains normal saline. The wound can be flushed in the order of hydrogen peroxide first and then normal saline, and then the wound surface is covered with a sterile dressing; the middle second bag contains cooling particles and distilled water. When in use, the distilled water cavity is squeezed to open the rubber stopper to mix the distilled water with the cooling particles; (without opening the controllable valve on the pipeline, the distilled water cavity cannot be squeezed to open the rubber stopper, that is, the first bag body, the second bag body and the third bag body are all in sealed packages. When the controllable valve is not opened, the pressure in the cooling particle cavity and the distilled water cavity of the third bag is balanced, and the installed rubber stopper will not fall off and seal. However, when the controllable valve on the pipeline is opened, the pressure in the cooling particle cavity decreases, and squeezing the distilled water cavity can push the rubber stopper out into the cooling particle cavity);

[0044] And it flows into the first and second bags through the controllable valves on both sides of the third bag body (at this time, the liquid in the first and third water bags has flowed out for wound flushing). After making the appropriate amount of liquid in the first, second, and third bags through the controllable valves, according to the anatomical position of the wound, the bag body can be wound or attached to the limb for cooling, and can be fixed with the adhesive patch on the water bag, which can realize the preliminary disinfection, flushing and rapid cooling of the wound, effectively protect the wound surface, reduce bleeding, and reduce the inflammatory reaction, reduce tissue swelling, and reduce cell damage.
