[0020] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0021] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] like Figure 1 As shown, the disposable sleeve-type hemostatic hemostatic device of the present application is composed of a sterile sleeve 1, a hemostatic ring 2, an inflatable tourniquet 3, an inflatable pressurizing device 4, a pressure gauge 5, etc.;

[0023] like Figure 1As shown, the sterile sleeve 1 is a cylindrical device that is sleeved on the patient's limbs and is made of elastic material. The exsanguination ring 2 and the inflatable tourniquet 3 are also made of elastic material with good elasticity and flexibility. The exsanguination ring 2 is designed in a sleeve type, which is convenient for fixing the device on the surgical site. The exsanguination ring 2 includes an elastic ring body 2.1, a valve 2.2 and a one-way air stop valve 2.3. The inflatable tourniquet 3 is set close to the exsanguination ring, and the pressure regulating device is used to adjust the inflatable tourniquet 3 to the set pressure, the exsanguination ring 2 is cut off, and then the inflatable tourniquet 3 is fixed with the fixing belt on the sterile sleeve. The inflatable pressurizing device 4 is used to adjust the pressure of the tourniquet to meet the needs of different surgical sites, adjust the pressure change according to the intraoperative situation, and extend the use time of the tourniquet; in this solution, the exsanguination ring 2 and the inflatable tourniquet 3 have the same structure but different functions.

[0024] The inflation and pressurization device 4 comprises a pressurized air bag 4.1, a one-way valve 4.2, a gas buffer tube 4.3 and a hose 4.4, which buffer the pressurized gas. The diameter of the gas buffer tube 4.3 is about twice that of the hose 4.4.

[0025] In this solution, the hose 4.4 is a Y-shaped structure, and a three-way is provided at its bifurcation. The airway guide of the three-way can be adjusted as needed. In order to pressurize the exsanguination ring 2 and the inflatable tourniquet 3 respectively, in addition to the three-way method, it can also be achieved by controlling the valves 2.2 on the two. When one of them needs to be inflated and pressurized, tighten the valve of the other that does not need to be pressurized. The branch pipe of the Y-shaped structure is at a long distance from the exsanguination ring 2 and the inflatable tourniquet 3, so they will not be restricted when they move.

[0026] When in use, the device is put on the patient's limb from the limb end to the proximal end, and the inflation status of the inflatable tourniquet 3 can be observed through the pressure gauge 5. The inflatable tourniquet 3 is pressurized by the inflation pressurizing device 4 and slides on the patient's limb to complete blood removal, which can quickly and effectively remove blood stasis and stop bleeding. The cut position of the sterile sleeve 1 exposes the surgical field, and the surgical field range can be expanded according to the surgical sterility requirements, and other parts can still be in a sterile state.

[0027] In actual application:

[0028] (1) First, according to the above requirements, various components involved in the sleeve-type hemostatic hemostasis device are manufactured;

[0029] (2) A cut is provided on the sterile cover 1 to expose the surgical field, so that the surgical field can be expanded according to the sterile requirements of the surgery;

[0030] (3) Putting a sterile cover 1 on the patient's limb, and filling the sterile cover 1 with a hemostatic ring 2 and an inflatable tourniquet 3;

[0031] (4) A traction belt 7 is tied to the two symmetrical sides of the blood-driving ring 2. When it is necessary to remove blood stasis and stop bleeding, the medical staff grabs the two traction belts 7 and pulls the blood-driving ring 2 to slide, thereby achieving the purpose of removing blood stasis and stopping bleeding. During the sliding process of the blood-driving ring 2, other components connected to the blood-driving ring 2 (such as the hose 4.4) will not flip over, but the sterile cover 1 will change;

[0032] (5) Adjust the inflatable tourniquet 3 to a proper position, adjust the pressure to a suitable pressure using the pressure regulating device, cut off the exsanguination ring 2, and fix the inflatable tourniquet 3 using the inflating and pressurizing device 4.

[0033] (6) In this solution, the inflation and pressurization device 4 and the pressure gauge 5 are both recyclable and reusable. In this solution, after adding the gauze layer 6, they can be reused many times.

[0034] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the utility model involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also includes other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) to form a technical scheme.
