Description

Technical Field

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

[0002] Existing tourniquets are usually made of natural rubber or special rubber, and come in long, flat strip and rubber tubing shapes. They are highly elastic and are commonly used for blood transfusion, blood draw, and hemostasis. They are reused after disinfection.

[0003] Existing rubber tourniquets suffer from problems such as hardening, brittleness, and decreased tensile strength when used in low-temperature environments, leading to a decline in rubber performance and loss of elasticity, thus affecting the hemostatic effect.

[0004] While existing pneumatic tourniquets can solve the above problems, they are usually a one-piece inflatable structure. An external pressure device is used to inflate and pressurize the entire tourniquet, and it is directly wrapped and fixed during fixation.

[0005] Although securing the limb is relatively convenient and quick, the entire strap is an inflatable structure that directly compresses the skin, which can easily cause skin damage and uneven force. Usually, it is necessary to wrap the limb evenly and flatly with a limb protector or paper cotton several times at the binding site, and then wrap it with a bandage twice to prevent it from bursting or falling off, which increases the operation steps and trouble. Utility Model Content

[0006] The purpose of this invention is to provide an inflatable tourniquet to solve the technical problem that in the prior art, inflatable tourniquets can easily cause skin damage by directly compressing the skin.

[0007] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution:

[0008] An inflatable tourniquet includes an inner bandage, an outer bandage on the inner bandage, and an airbag belt at one end of the outer bandage. The outer bandage wraps around the limb and self-fixes to form a wrapping structure. The airbag belt wraps around the limb and wraps the outer bandage inside to form a covering structure.

[0009] The inner strap covers the length of the combination of the outer strap and the airbag strap in the longitudinal direction, and the outer strap and the airbag strap are arranged parallel to the inner strap to form a double-layer covering structure.

[0010] As a preferred embodiment of this utility model, the two ends of the outer strap are respectively provided with a longitudinal magnetic strip and a transverse magnetic strip, the longitudinal magnetic strip and the transverse magnetic strip are arranged perpendicular to each other, and after the outer strap wraps around the limb, the longitudinal magnetic strip and the transverse magnetic strip abut against each other to form a fixed structure.

[0011] As a preferred embodiment of this utility model, the inner side of the airbag strap near the outer strap has a rough surface, and the outer side of the airbag strap near the outer strap has a hook surface. After the airbag strap surrounds the outer wall of the outer strap, the rough surface and the hook surface move to abut against each other to form a fixed structure.

[0012] As a preferred embodiment of the present invention, one end of the airbag belt is provided with an air supply pipe, the inner wall of the air supply pipe is provided with a baffle, the baffle rotates around its connection with the air supply pipe to form an opening and closing structure, and a connecting pipe is provided at one end of the air supply pipe to movably abut against the baffle.

[0013] As a preferred embodiment of this utility model, the connecting pipe includes an inner connecting pipe and an outer connecting pipe. One end of the inner connecting pipe penetrates the inner wall of the outer connecting pipe and extends to the inner wall of the gas transmission pipe. The outer connecting pipe and the baffle are movably abutted to form a communication structure. The outer connecting pipe is sleeved on the outer wall of the gas transmission pipe and fixed by a threaded connection.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] This invention employs a double-layer splicing structure to form a tourniquet with dual fixation. The inner layer of the bandage isolates the skin, reducing damage to the skin surface. The outer layer of the air bladder adjusts the pressure by inflation to achieve hemostasis or treatment. The integrated splicing form constitutes a double-layer covering structure, which is better suited for low-temperature environments, facilitates flat wrapping and even force distribution, and does not easily affect the wrapping and stability of the isolation material before or after inflation, thus reducing discomfort to the patient.

[0024] 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.

[0025] like Figure 1 As shown, this utility model provides an inflatable tourniquet, including an inner bandage 10, an outer bandage 20 on the inner bandage 10, and an airbag 30 at one end of the outer bandage 20. The outer bandage 20 is self-fixed after wrapping around the limb to form a wrapping structure, and the airbag 30 wraps around the limb to wrap the outer bandage 20 to form a covering structure.

[0026] The inner strap 10 covers the length of the combination of the outer strap 20 and the airbag strap 30, and the outer strap 20 and the airbag strap 30 are arranged parallel to the inner strap 10 to form a double-layer covering structure.

[0027] This invention employs a double-layer splicing structure to form a tourniquet with dual fixation. The inner layer of the bandage isolates the skin, reducing damage to the skin surface. The outer layer of the air bladder adjusts the pressure by inflation to achieve hemostasis or treatment. The integrated splicing form constitutes a double-layer covering structure, which is better suited for low-temperature environments, facilitates flat wrapping and even force distribution, and does not easily affect the wrapping and stability of the isolation material before or after inflation, thus reducing discomfort to the patient.

[0028] After the wound is isolated by covering it with gauze, the inner bandage 10 is used to isolate the outer bandage 20 from the gauze again on the inside of the outer bandage 20. The inner bandage 10 is made of natural latex, which helps to isolate tissue fluid and medicine that seep into the wound, helps to keep the outer bandage 20 and the air bag 30 clean, and helps to reduce the infiltration of bacteria into the wound area. After the air bag 30 is wrapped around the outer bandage 20 for fixation, pressure hemostasis can be applied.

[0029] It is convenient and quick to fix, and it is easy to adjust the pressure on the wound site, thereby reducing the failure of traditional rubber tube knotting hemostasis. It also helps to reduce the discomfort caused to patients when using pressure hemostasis, and can reduce the limitations of traditional rubber tubes in low temperature environments. It is easy to carry and can be used in more application scenarios.

[0030] like Figure 1 and Figure 2 As shown, the two ends of the outer strap 20 are respectively provided with a longitudinal magnetic strip 21 and a transverse magnetic strip 22. The longitudinal magnetic strip 21 and the transverse magnetic strip 22 are arranged perpendicular to each other. After the outer strap 20 wraps around the limb, the longitudinal magnetic strip 21 and the transverse magnetic strip 22 abut against each other to form a fixed structure.

[0031] When the outer bandage 20 and the inner bandage 10 are wrapped around the limb together, the overlapping of the longitudinal magnetic strip 21 and the transverse magnetic strip 22 is conducive to fixing the outer bandage 20, and at the same time, it is convenient to wrap and fix the gauze and other items at the wound together.

[0032] The inner bandage 10 helps to isolate the wound from the outer bandage 20, while also achieving waterproofing and seepage prevention. It can prevent tissue fluid and medication from penetrating the wound and reduce the risk of infection caused by external bacteria penetrating the wound.

[0033] like Figure 1 As shown, the inner side of the airbag strap 30 near the outer strap 20 is provided with a rough surface 31, and the outer side of the airbag strap 30 near the outer strap 20 is provided with a hook surface 32. After the airbag strap 30 surrounds the outer wall of the outer strap 20, the rough surface 31 and the hook surface 32 move and abut against each other to form a fixed structure.

[0034] After the outer bandage 20 and inner bandage 10 are wrapped and secured, the airbag strap 30 is then wrapped around the outer bandage 20 again. The end of the airbag strap 30 near the hook surface 32 is covered and overlapped on the rough surface 31 to secure the airbag strap 30. At this point, the airbag strap 30 is secured, and inflation and pressure can be applied for hemostasis or treatment.

[0035] like Figure 1 and Figure 3 As shown, an air supply pipe 40 is provided at one end of the airbag belt 30. A baffle 41 is provided on the inner wall of the air supply pipe 40. The baffle 41 can rotate around the connection between itself and the air supply pipe 40 to form an opening and closing structure. A connecting pipe 42 is provided at one end of the air supply pipe 40 to movably abut against the baffle 41.

[0036] The airbag belt 30 is connected to an external inflatable airbag or air pump through the air supply pipe 40 for inflation and pressurization. A plug is connected to the outer wall of the air supply pipe 40 by a rubber rope. After inflation, the plug is used to seal and fix the airbag.

[0037] During inflation, the connector 42 is installed at one end of the air supply pipe 40. The baffle 41 is pushed open by the connector 42, so that the air supply pipe 40 and the connector 42 are connected. At this time, the gas from the external airbag or air pump can be sent into the airbag belt 30 through the connector 42.

[0038] After inflation is complete, remove the tube 42, return the baffle 41 to its initial position, seal the air supply tube 40, and then seal it with the plug. The airbag belt 30 can then be detached and worn independently.

[0039] like Figure 3 As shown, the connector 42 includes an inner connector 421 and an outer connector 422. One end of the inner connector 421 penetrates the inner wall of the outer connector 422 and extends to the inner wall of the gas transmission pipe 40. The outer connector 422 movably abuts against the baffle 41 to form a communication structure, and the outer connector 422 is sleeved on the outer wall of the gas transmission pipe 40 and fixed by threaded connection.

[0040] When installing the connector 42, the connector 42 is rotated and installed at one end of the gas supply pipe 40. The outer connector 422 is threadedly connected and fixed to the gas supply pipe 40, which makes it easy to keep the inner connector 421 in a suitable position in the gas supply pipe 40, so that the inner connector 421 continuously presses and opens the baffle 41, which is convenient for inflation and pressurization, and is easy to assemble and use.

[0041] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
