Description

Technical Field

[0001] The utility model belongs to the technical field of hemostatic appliances, in particular to a simple air bag pressing hemostatic device. Background Art

[0002] Hemostasis is the process of quickly stopping bleeding through specific means. The effectiveness of hemostasis varies from person to person, with some achieving it quickly, others slowly, depending on the platelet count. Normally, bleeding caused by damaged small blood vessels stops on its own within a few minutes, a phenomenon known as physiological hemostasis. However, bleeding spots that do not stop on their own within a short period of time require other methods of hemostasis. Compression hemostasis is the most common clinical hemostasis method. It works by applying a certain amount of pressure to shrink or close the ruptured blood vessel. Subsequently, as blood flow slows, platelets, fibrin, and red blood cells quickly form a clot, stopping the bleeding. Numerous compression hemostasis devices are commercially available, but the airbag method is the most effective.

[0003] In clinical practice, patients typically apply pressure to stop bleeding after needle removal during injections and infusions. This is not conducive to freeing their hands and can easily lead to displacement or insufficient pressure, resulting in subcutaneous purple bruising. To address these issues, a hemostatic device is urgently needed to solve these problems. Utility Model Content

[0024] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of the described features.

[0027] Reference Figure 1 、 Figure 2 This embodiment discloses a simple airbag pressing hemostat, comprising an airbag seat 1 and two chain belts 3 connected to the airbag seat 1. An airbag 2 is provided under the airbag seat 1. The two chain belts 3 each comprise a plurality of chain units, each of which is detachable. The two chain belts 3 are connected by a connector. During use, the chain units 31 are added or reduced according to the bleeding location of the patient, so that the chain belt 3 can be fixed at different locations on the patient, and the airbag seat 1 and the airbag 2 are used to press on the bleeding point to stop bleeding. Since the airbag seat 1 and the airbag 2 are connected by a one-way air valve 12, when stopping bleeding, the airbag 2 is inflated with a syringe through the one-way air valve 12, and the bleeding point of the patient is quickly and effectively compressed to stop bleeding.

[0028] like Figure 3 、 Figure 4As shown, the chain unit 31 includes a spring belt 311, a pin holder connected to one end of the spring belt 311, and a pin 313 connected to the other end of the spring belt 311. The pin holder is provided with a pin slot 3121, and the pin 313 can be inserted into the pin slot 3121 of another chain unit 31. The airbag seat 1 is detachably connected to the chain unit 31, which is also provided with a pin slot 3121. A chain unit 31 can be connected to another chain unit 31 via the pin 313 and the pin slot 3121, thereby forming a chain belt 3 with variable length. During use, the pin 313 of one chain unit 31 is inserted into the pin slot 3121 of the airbag seat 1, and the pin 313 of another chain unit 31 is then inserted into the pin slot 3121 of the chain unit 31, and the length of the chain belt 3 is increased sequentially until the desired length is reached.

[0029] Reference Figure 5 The connector includes a spring belt 311 and two pins 313 connected to the ends of the spring belt 311. The pins 313 are detachably connected to the pin slots 3121 of each chain unit 31. The two pins 313 of the connector are respectively inserted into the pin slots 3121 of the chain units 31 on the two chain belts 3. After the airbag seat 1 and airbag 2 are fixed to the patient's bleeding site, the airbag 2 is inflated with a syringe through the one-way air valve 12 to apply pressure to the patient's bleeding point to stop the bleeding.

[0030] Further, refer to Figure 3 、 Figure 4 In order to facilitate the taking of the chain unit 31, a protrusion for easy taking and pressing is provided at the end of the pin seat away from the pin slot 3121. Pinching the protrusion makes it easier to assemble and disassemble the chain units 31. In addition, in order to make the connection between the chain units 31 more stable, a limiting block 3131 is provided on the side of the latch 313 close to the spring belt 311, and a limiting groove is provided in the pin slot 3121 corresponding to the limiting block 3131. Furthermore, in order to enhance its stability, the limiting block 3131 includes a plurality of limiting units, the limiting units have different widths, and the limiting grooves are correspondingly provided with deep grooves of different depths, and the wider limiting units are all made of deformable elastic material. Figure 3 As shown, this embodiment is provided with three limiting units. The limiting unit located in the middle is a wider limiting unit, that is, a limiting unit made of a deformable elastic material. When the latch 313 of a chain unit 31 is inserted into the pin slot 3121 of another chain unit 31, the middle limiting unit is squeezed and deformed until it engages with the deep slot, at which point it returns to its original position under the action of elastic force. The middle limiting unit and the limiting units on both sides, the pin slot 3121, and the deep slot form a step-like misalignment, thereby further stabilizing the connection between the chain units 31. When disassembly is required, a slight force can cause the middle limiting unit to deform and then slide out of the deep slot, allowing the chain units 31 to be disassembled.

[0031] Reference Figure 2Because the airbag 2 may be contaminated by the patient's wound, the airbag holder 1 and airbag 2 are detachably connected. This embodiment utilizes a threaded detachable connection. After use, the contaminated airbag 2 can be loosened and removed, and a new one screwed in. Replacing the airbag 2 allows for easy reuse.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
