Description

A wound dressing device suitable for trauma first aid

technical field

The utility model relates to the field of medical appliances, in particular to a wound bandaging device suitable for trauma first aid.

Background technique

At present, with the rapid development of transportation and construction brought about by social development, there are more and more traumas caused by various high-violence injuries. Arterial blood vessels, leading to local bleeding, and finally, in most cases, the patient will lose too much blood at the emergency scene, which will cause the patient's shock symptoms, and severe cases may lead to death. This kind of patients poses a severe test to the ambulance medical staff of the pre-hospital first aid 120. How to deal with wounds and stop bleeding at the first aid scene is an urgent matter.

At present, in the process of medical emergency, there are traditionally two methods for the treatment of open wounds: the first one is to give a large amount of gauze to the local wound to fill and cover it, and then tie a bandage and pressurize it. The disadvantage of the method is that the strength of the local pressurization often depends on the on-site emergency personnel, and it may be too tight or too loose, which often does not achieve a good hemostatic effect, causing the patient to lose a lot of blood even after treatment. At the same time, this type of pressurized gauze often also prevents further observation of the effect of wound hemostasis, so that emergency personnel cannot obtain the first-time information to adjust the strength and intensity of the bandage; If it is resolved, a tourniquet can be used at the proximal end of the limbs to block the blood flow at the proximal end of the patient, so as to achieve the effect of hemostasis. There are certain disadvantages in this method, mainly in that while hemostasis, the blood flow of the whole limb is sacrificed, which affects the metabolism of the whole limb. Even if the blood flow recovers later, it often causes damage to the limbs to varying degrees. At the same time, this type of hemostasis technology has strict requirements on the hemostasis time, which cannot exceed one hour. The tourniquet must be loosened to ensure that the limbs do not have the possibility of necrosis. This period of time will inevitably increase the bleeding of the wound, and it is difficult to achieve hemostasis throughout the process. Effect.

Utility model content

The technical problem mainly solved by the utility model is to provide a wound dressing device suitable for trauma first aid, which can observe the bleeding after the wound is bandaged, and only pressurize the part of the wound without affecting the blood flow of the whole limb, and at the same time, the pressure is controllable , in order to achieve the best hemostatic effect without affecting the blood supply of the limbs.

In order to solve the above technical problems, a technical solution adopted by the utility model is to provide a wound dressing device suitable for trauma first aid, including: a bandage, a pressure valve, an air release valve and an inflatable air bag, the pressure valve, the air release valve The inflatable air bag and the inflatable air bag are sequentially connected with the bandage through the inflatable tube, and the bandage contains a transparent window.

In a preferred embodiment of the present invention, the bandage includes an outer bandage and an inner bandage with the same structure, and the outer bandage and the inner bandage are bonded to form a cavity, and the cavity An inflatable tube interface is connected to one end of the inflatable tube, and the inflatable air bag is connected to the other end of the inflatable tube.

In a preferred embodiment of the present invention, the outer surface of one side of the outer bandage and the outer surface of the other side of the inner bandage contain adhesive strips that cooperate with each other.

In a preferred embodiment of the present utility model, the transparent window is a gel tape that fits the outer bandage and the inner bandage around.

In a preferred embodiment of the present invention, the transparent window is located in the middle of the outer bandage and the inner bandage.

The beneficial effects of the utility model are:

1. Only pressurize the part of the wound, without affecting the blood flow of the whole limb;

2. A transparent window is set at the location of the local wound dressing, so that the bleeding after the wound dressing can be observed at any time;

3. According to the bleeding situation after bandaging and the blood supply of the distal limbs, the pressure of the bandaging can be adjusted at any time to achieve the best hemostatic effect without affecting the blood supply of the limbs.
