Embodiment 1

[0033] Such as Figure 1 to Figure 6 , a first aid hemostatic stick for gunshot wounds, comprising a core tube 10, an inflatable cuff 20 and a hemostatic layer 30.

[0034] The front end of the core tube is a closed end, and the core tube is provided with an inflation hole 11 communicating with the inner cavity of the inflatable cuff. In order to facilitate insertion into the wound, the front end of the core tube is provided with a ball head 12 . The rear end of the core tube is provided with an inflation port 13, and the inflation port is provided with a one-way valve so that the gas can only enter the core tube in one direction. The inflation port of the present embodiment is the inflation port connected with the syringe 40, such as Figure 6 shown. The diameter of the core tube is 2 mm to 4 mm, and the wall thickness of the core tube is 0.5 mm to 1 mm. The material that is more suitable for the core tube is a non-metallic material that has good rigidity and can be prope...

Embodiment 2

[0045] Such as Figure 7 , a first aid hemostatic stick for bullet wounds, this embodiment is an improvement of Embodiment 1.

[0046] In this embodiment, the rear end of the core tube is not only provided with an inflation port 13, but also provided with a detection port 14, and the detection port is also provided with a one-way valve. The detection port is used to connect the pressure gauge 60, which can detect the inflation pressure of the inflatable cuff. During the first aid process, the ambulance personnel can control and adjust the inflation pressure through the pressure gauge to obtain the best first aid effect. Researchers can further study and improve treatment methods and equipment by collecting pressure data of inflatable cuffs. The pressure gauge can adopt various styles such as straight rod type and circular type, and the present embodiment adopts a pressure gauge with a circular head.

[0047] In this embodiment, the detection port 14 also adopts the same str...

Embodiment 3

[0049] Such as Figure 8 , a first aid hemostatic stick for bullet wounds, this embodiment is an improvement of Embodiment 1.

[0050]In this embodiment, as another inflation solution, a compressed gas cylinder 50 is provided at the rear end of the core tube, the compressed gas cylinder is connected to the core tube, and a pressing valve 51 is provided on the compressed gas cylinder. The volume and pressure of the gas cylinder are determined according to the design volume and pressure of the inflatable cuff. In order not to make the inflation pressure of the inflatable cuff too high or too low. For portability, the capacity of the compressed gas cylinder is 5ml to 10ml. The gas pressure in the compressed gas cylinder depends on the capacity of the compressed gas cylinder and the size of the hemostatic layer. According to experience, the gas pressure in the compressed gas cylinder needs to be in the range of 0.1MPa ~ 1.2MPa. Appropriate capacity and pressure of the compress...

Abstract

The invention relates to a bullet wound first-aid hemostasis stick, which comprises a core pipe, an inflation cover bag and a hemostasis layer, wherein the front end of the core pipe is a sealed end,the inflation cover bag is in sleeving to the front part of the core pipe through an airtight way, the core pipe is provided with an inflation hole which communicates with the inner cavity of the inflation cover bag, and the hemostasis layer is in sleeving to the outer part of the inflation cover bag. The bullet wound first-aid hemostasis stick has the beneficial effects that the hemostasis stickwhich can be deeply inserted into a wound is adopted, a hemostasis material can expand through the inflation cover bag to pack and fully fill the wound and compress the artery, a hemostasis function can be quickly generated on a deep position of the wound, and a site disposal effect of a wounded person can be obviously improved. A syringe is adopted to expand the inflation cover bag so as to adaptto configuration and carrying of first-aid equipment. A compression gas cylinder is adopted to expand the inflation cover bag, and utilization convenience and disposal efficiency are further improved.

Description

technical field [0001] The invention belongs to wound first aid materials, in particular to a first aid hemostatic stick for bullet wounds. Background technique [0002] After the human body suffers from bullet wounds (such as bullet wounds, shrapnel wounds or knife wounds), deep wounds will occur, and arteries are often injured, causing massive bleeding and life-threatening. Therefore, emergency treatment at the trauma scene is required. Timely hemostasis of the wound is extremely important to save the lives of the wounded. The current common emergency treatment methods are filling hemostatic material and wound dressing, but these rescue measures can only treat the superficial layer of the wound and the skin, and the treatment effect on deep wounds and arterial wounds is limited, and the treatment process is more complicated and inefficient. , can not be well adapted to the battlefield and emergency situations. The research team led by Chai Jiake developed a hemostatic m...
