Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an airbag tourniquet. Background Technology

[0002] A balloon tourniquet is a medical emergency device that applies pressure to the bleeding site of a limb by inflating an inflatable balloon, thereby temporarily blocking blood flow to achieve hemostasis. It is commonly used for trauma first aid, surgical procedures, or compression hemostasis after radial artery catheterization. When using it, the pressure should be adjusted according to the patient's condition and the application time should be controlled to avoid tissue damage. In a hemostatic wristband published in CN215458370U, an inflatable component inflates the pressure balloon, causing the pressure balloon to expand and squeeze the hemostatic pad to apply pressure to the patient's puncture site to stop bleeding.

[0003] However, the aforementioned hemostasis methods involve completely wrapping the patient's wrist with an inflated wristband. This tight bandage causes significant tension and discomfort for the patient. In contrast, patients using pneumatic tourniquets typically require long-term injection therapy, and the tourniquet is worn for extended periods. The inflated wristband completely covering the wrist can lead to numbness and impaired blood circulation. Furthermore, the inflated inner circumference of existing pneumatic tourniquets is only about 30% of the wrist circumference. Given the significant differences in limb circumference among patients, and the presence of muscle bulges or depressions in certain areas, the tourniquet may not evenly compress blood vessels after inflation. This results in uneven pressure distribution within the pneumatic tourniquet, with higher pressure in the center and lower pressure at the edges, leading to inconsistent hemostasis among patients. Utility Model Content

[0004] The purpose of this invention is to provide an air-filled tourniquet, which solves the problem of inconsistent hemostatic effects caused by patients with different limb circumferences in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an airbag tourniquet, comprising a fixing frame and a binding strap fixedly installed on the side end face of the fixing frame. A rough-textured adhesive is provided at the middle of the upper surface of the binding strap, and a hook-shaped adhesive is provided at the end of the lower surface of the binding strap. A U-shaped contour groove is provided on the lower surface of the fixing frame, and positioning sponges are provided on the two inner side walls of the U-shaped contour groove. A connector is installed on one side surface of the fixing frame, and an air supply tube is connected to the connector.

[0006] Preferably, the inner surface of the positioning sponge is provided with an L-shaped concave surface, and the two L-shaped concave surfaces are positioned opposite each other.

[0007] Preferably, the other end face of the fixing frame is provided with a through groove, which is connected to the end of the binding strap.

[0008] Preferably, the inner top surface of the U-shaped contour groove is provided with a mounting groove, and the connector is connected to the interior of the mounting groove.

[0009] Preferably, an airbag is provided on the inner side of the mounting groove, and the air supply pipe is connected to the airbag through a connector.

[0010] Preferably, the textured surface and the hook surface are bonded together.

[0011] Preferably, the mounting bracket is made of acrylic material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The pneumatic tourniquet provided by this utility model, through the design of a U-shaped contour groove and a positioning sponge, allows the tourniquet to fit snugly against the patient's wrist, and utilizes the elasticity of the positioning sponge to adapt to different patients' forearm widths. This design ensures that the tourniquet can be adjusted according to the circumference of different patients' limbs, thereby improving the accuracy and effectiveness of hemostasis. The L-shaped concave surface further enhances the wrapping effect of the positioning sponge on the side of the wrist, making the tourniquet more stable when fixed, less prone to slippage or displacement, thus ensuring the continuity of hemostasis.

[0013] 2. The air-cushioned tourniquet provided by this utility model compresses the bleeding site through the rapid expansion of the air cushion, while the elasticity of the positioning sponge provides leeway for the wrist circumference. This design ensures that the tourniquet compresses the bleeding site without causing excessive pressure on other parts of the wrist, thereby reducing wrist discomfort. The adhesive side and hook side of the tourniquet are bonded together, making the tourniquet easier and more secure to fix, while avoiding the tightness and discomfort that may be caused by traditional tourniquets, thus improving patient comfort.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0018] Combination Figure 1 The present invention relates to an airbag-type tourniquet, comprising a fixing frame 1 and a binding strap 2 fixedly installed on the side end face of the fixing frame 1. The binding strap 2 has a rough-textured adhesive 21 at the middle of its upper surface and a hook-textured adhesive 22 at the end of its lower surface. The fixing frame 1 has a U-shaped contour groove 3 on its lower surface, and positioning sponges 5 are provided on the two inner side walls of the U-shaped contour groove 3. A connector 11 is installed on one side surface of the fixing frame 1, and an air supply tube 4 is connected to the connector 11. Through the precise design of the U-shaped contour groove 3 and the positioning sponges 5, the tourniquet allows the airbag to compress only the bleeding site of the wrist, avoiding excessive compression of other healthy parts of the wrist when using the traditional tourniquet for full compression hemostasis. This not only improves the hemostatic effect but also reduces damage to the tissues around the wrist.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Combination Figures 1-4 The inner surface of the positioning sponge 5 is provided with an L-shaped concave surface 51. The two L-shaped concave surfaces 51 are positioned opposite each other, so that the positioning sponge 5 can fit more tightly when it is attached to the wrist, effectively preventing the tourniquet from slipping or shifting during the fixation process. The other end face of the fixation frame 1 is provided with a through groove 12, which is wrapped around the end of the binding strap 2. The inner top surface of the U-shaped contour groove 3 is provided with an installation groove 13. The connector 11 is connected to the inside of the installation groove 13. An air bag 6 is provided inside the installation groove 13. The air supply tube 4 is connected to the air bag 6 through the connector 11. The textured surface 21 and the hook surface 22 are bonded together. The fixing frame 1 is made of acrylic material. The U-shaped contour groove 3 is the wrist fixing groove. Since the U-shaped wrist fixing groove has only three sides, it can specifically compress the hemostatic part of the wrist. The other parts are fixed by the bandage 2. Compared with the inflation of the airbag, it puts less pressure on the wrist, avoiding the wrist congestion caused by prolonged discomfort. In addition, the soft material of the positioning sponge provides good cushioning. Therefore, patients will feel more comfortable when wearing the tourniquet, reducing the tightness and discomfort that traditional tourniquets may cause.

[0021] In this embodiment, the patient's wrist is covered inside the fixation frame 1 by the U-shaped contour groove 3. The elasticity of the positioning sponge 5 is used to adapt to the width of the patient's forearm. The L-shaped concave surface 51 increases the wrapping effect of the positioning sponge 5 on the side of the wrist. The tourniquet 2 is wrapped around the lower end of the wrist, and its end passes through the lower groove of the insertion groove 12. The end of the tourniquet 2 is pulled out from the upper groove of the insertion groove 12. After wrapping and tightening, the rough-faced adhesive 21 and the hook-faced adhesive 22 are positioned opposite each other and are bonded together to complete the fixation of the tourniquet. The air supply tube 4 is connected to the pressure bag 6, and the air bag 6 quickly inflates to compress the bleeding site. The elasticity of the positioning sponge 5 provides extra space for the circumference of the wrist, which can adapt to the limb circumference of different patients, and only applies pressure to the bleeding site of the wrist, without causing discomfort to other parts of the wrist.
