Problems solved by technology

[0003] 1. For massive hemorrhage caused by penetrating gunshot wounds or large blood vessel injuries in the ballistic trajectory of blind pipe wounds, if traditional treatment methods are used, only hemostatic treatment or external pressure on the wound on the skin surface cannot effectively stop the bleeding, and only hospital-based methods can be used. Traditional vascular surgery sutures and repairs, but the battlefield conditions are not met, resulting in a large number of casualties on the battlefield
[0004] 2. Although the currently installed tourniquet and the pressurized hemostatic device at the junction of the limbs and trunk are effective in hemostasis, in addition to the cumbersome operation, the use of compression of the proximal blood vessels to achieve hemostasis will cause ischemia in the distal limbs and cause follow-up Treat the accompanying limb necrosis, the toxic metabolites of necrotic tissue enter the blood circulation, leading to heart and kidney failure and death, increasing the disability rate of amputation
[0005] 3. The use of traditional bandages and triangular scarves is ineffective for deep or superficial large blood vessel injuries.

Embodiment 1

[0035] see Figure 1-4 , a portable rapid hemostasis device for massive bleeding in the ballistic trajectory of gunshot wounds, including acetal polymer materials produced by water-absorbing and blood-absorbing swellable materials (water-absorbing and blood-absorbing swellable materials can be produced by reacting polyvinyl alcohol and aldehydes, high-swelling Chitosan sponge, rena hydrogel and other materials with water absorption and swelling function) made of hemostatic filler 1, positioning piece 2 and protective bag 3; one end of the protective bag 3 is open and the non-closed end is fixedly connected to the On the positioning member 2, the inner space of the protective bag 3 forms a protective cavity; the part of the positioning member 2 located in the protective cavity is provided with a slot 21 and two ends are respectively connected to the external space and the protective cavity The through hole 22 of the body; the hemostatic filler 1 is arranged in the protective ca...

Embodiment 2

[0040] see Figure 5-8 , in this embodiment, the positioning member 2 is a square support, and the unclosed end of the protective bag 3 is fixedly connected to the outer edge of one end surface of the square support; the through hole 22 is vertically penetrated in the The center of the square support, the card slot 21 penetrates from one end surface of the square support in the protection cavity to the inside of the square support, and the card slot 21 and the The above-mentioned through holes 22 are arranged crosswise.

[0041] The use process of this embodiment is as follows: place the square support at the bullet hole, take out the front end of the hemostatic filler 1 from the slot 21 inside the square support through the protective bag 3, turn the hemostatic filler 1 slightly The hemostatic filler 1 is positioned in the through hole 22, and the rear end of the hemostatic filler 1 is pushed to push the hemostatic filler 1 into the bullet hole.

Embodiment 3

[0043] see Figure 9-12 , in this embodiment, the positioning member 2 is a hemispherical support, and the non-closed end of the protective bag 3 is fixedly connected to the outer edge of the plane end of the hemispherical support; the through hole 22 is penetrated in The center of the hemispherical support is perpendicular to the plane end, the slot 21 penetrates from the plane end of the hemispherical support to the inside of the hemispherical support, and intersects with the through hole 22 .

[0044] The use process of this embodiment is as follows: place the hemispherical support at the bullet hole, take out the front end of the hemostatic filler 1 from the slot 21 inside the hemispherical support through the protective bag 3, and turn the hemostatic filler 1 slightly The hemostatic filler 1 is positioned in the through hole 22, and the rear end of the hemostatic filler 1 is pushed to push the hemostatic filler 1 into the bullet hole.

Abstract

The invention relates to a portable rapid haemostatic device for massive haemorrhage in a bullet injury trajectory. The portable rapid haemostatic device comprises a haemostatic filler made of a material expandable after water absorption and blood absorption, a locating piece and a protective bag, wherein one end of the protective bag is arranged in an open mode, and the non-closed end of the protective bag is fixedly connected to the locating piece; a protective cavity is formed in the inner space of the protective bag; the part of the locating piece, located in the protective cavity, is provided with a neck and equipped with a through hole having two ends communicated with the external space and the protective cavity correspondingly; and the haemostatic filler is arranged in the protective cavity, and the front end of the haemostatic filler is detachably connected in the neck.

Description

technical field [0001] The invention relates to a portable rapid hemostasis device for hemorrhage in the ballistic trajectory of a gunshot wound, belonging to the technical field of emergency medical equipment. Background technique [0002] Being hit by bullets or shrapnel on the battlefield will form a bullet hole in the body, usually a single-entry blind tube injury or a single-entry single-exit penetrating wound. There are usually three methods of treatment: 1. Hemostasis through surgery; but it cannot be effectively implemented under battlefield conditions; 2. Use a tourniquet or a pressurizer; the operation is cumbersome; However, these traditional methods all have different defects: [0003] 1. For massive hemorrhage caused by penetrating gunshot wounds or large blood vessel injuries in the ballistic trajectory of blind pipe wounds, if traditional treatment methods are used, only hemostatic treatment or external pressure on the wound on the skin surface cannot effecti...
