[0005] An airbag compression tourniquet comprises a tourniquet body, which comprises an airbag layer and a soft cushion layer, wherein the airbag layer comprises a placement layer for accommodating an inflatable airbag and a binding mechanism, wherein the binding mechanism is arranged on both sides of the placement layer, and the binding mechanism comprises no less than two groups of interconnected connectors, and the connection length between the connectors is adjustable; the soft cushion layer is arranged on the side of the airbag layer close to the skin, and comprises a cotton pad layer and a skin-protecting membrane layer; the inflatable airbag is detachably mounted on the tourniquet body, and an air inlet pipe is mounted on one side of the inflatable airbag, and an air outlet pipe is mounted on the other side, wherein a micro air pump is mounted on the air inlet pipe, and a throttle and air release valve and a timing switch are mounted on the air outlet pipe.

[0006] By adopting the above technical solution, the airbag layer provided on the tourniquet body is used to place the inflatable airbag, and the pressure of the tourniquet on the patient is adjusted by the air intake and air discharge through the air outlet pipe on the inflatable airbag. The inflatable airbag is placed in the placement layer in an uninflated state, and the inflatable airbag is supplied with air through the micro air pump on the air intake pipe. When the inflatable airbag is used on the patient in the inflated state, the gas in the inflatable airbag is intermittently and stably released through the throttle deflation valve and timing switch provided on the air outlet pipe, thereby avoiding peripheral circulation obstruction caused by artificial bundling. The binding mechanisms arranged on both sides of the placement layer can fix the tourniquet to the patient's body. Binding mechanisms of different lengths can be selected according to the location of the patient's wound, wherein there are no less than two groups of interconnected connectors in the binding mechanism. The connection method of more than two groups of connectors can improve the stability of the tourniquet fitting the patient's wound and can meet the needs of hemostasis of wounds like joints. The connection length between the connectors can be adjusted as needed to fully and stably fix the tourniquet to the patient's body. The soft pad layer on the inner side of the airbag layer is provided with a protective membrane layer on the cotton pad layer.

Furthermore, perforations are provided at the top of the placement layer for the passage of air inlet and outlet pipes. The placement opening is secured with Velcro or snaps, thereby securing the inflatable airbag within the placement layer. When inflated, the inflatable airbag within the placement layer compresses the elastic bandage below to increase and decrease pressure on the patient's wound. Furthermore, the separate design between the inflatable airbag and the tourniquet body allows for the repeated use of the airbag; only the tourniquet body needs to be replaced after each use, effectively reducing the cost of using a tourniquet with an airbag.

[0011] Preferably, the binding mechanism connectors are distributed horizontally, wherein the connectors include an elastic connector on both sides of a free end on one side and a clamping seat on the free end on the other side, wherein a plurality of claws are provided on both sides of the elastic connector, and a clamping hole corresponding to the clamping claw is provided in the clamping seat.

[0012] Preferably, the height inside the card hole is adapted to the thickness of the claw, the claw is in the shape of a right-angled triangular prism, and the two side surfaces of the card hole are provided with right-angled triangular prism-shaped card grooves adapted thereto, wherein the hypotenuse surface of the right-angled triangular prism corresponds to the hypotenuse surface of the right-angled triangular prism-shaped card groove.

[0015] Preferably, the protective film layer is a silicone layer or a polytetrafluoroethylene coating.

[0016] By adopting the above technical solution, the cotton pad layer in the soft pad layer is fitted with the bottom of the placement layer, which can improve the softness of the contact with the patient's wound, and a skin protection film layer is provided on the cotton pad layer, which can reduce the film material on the skin when untying the tourniquet, thereby reducing the pulling pain.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application uses a throttle valve and a timer switch on the outlet pipe to intermittently and stably release the gas in the inflatable airbag, thereby avoiding peripheral circulation obstruction caused by artificial binding;

[0019] 2. In the present application, a protective film layer is provided on the cotton pad layer as the soft pad layer on the inner side of the airbag layer. The protective film layer can avoid the pulling pain when untying the tourniquet. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is combined with Figure 1 This application is described in further detail.

[0023] The embodiment of the present application discloses an airbag compression tourniquet.

[0024] Reference Figure 1 , an airbag compression tourniquet, comprising a tourniquet main body 1, the tourniquet main body 1 comprising an airbag layer 11 and a soft pad layer 12, wherein the airbag layer 11 comprises a placement layer 111 for accommodating an inflatable airbag 3 and a binding mechanism 112, the binding mechanism 112 being arranged on both sides of the placement layer 111, and the binding mechanism 112 comprises no less than two groups of interconnected connectors 2, and the connection length between the connectors 2 is adjustable; the soft pad layer 12 is arranged on the side of the airbag layer 11 close to the skin, comprising a cotton pad layer 121 and a skin protective film layer 122; the inflatable airbag 3 is detachably mounted on the tourniquet main body 1, an air inlet pipe 31 is mounted on one side of the inflatable airbag 3, and an air outlet pipe 32 is mounted on the other side, wherein the air inlet pipe 31 is mounted with a micro air pump 311, and the air outlet pipe 32 is mounted with a throttle deflation valve 321 and a timing switch 322. The airbag layer 11 provided on the tourniquet body 1 is used to place the inflatable airbag 3. The pressure of the tourniquet on the patient is adjusted by the air intake pipe 31 and the air discharge pipe 32 on the inflatable airbag 3. The inflatable airbag 3 is placed in the placement layer 111 in an uninflated state, and the inflatable airbag 3 is supplied with air through the micro air pump 311 on the inflatable airbag 3. When the inflatable airbag 3 is used on the patient in the inflated state, the gas in the inflatable airbag 3 is intermittently and stably discharged through the throttle deflation valve 321 and the timing switch 322 provided on the outlet pipe 32 to avoid peripheral circulation obstruction caused by artificial bundling. The binding mechanisms 112 arranged on both sides of the placement layer 111 can fix the tourniquet to the patient's body. Binding mechanisms 112 of different lengths can be selected according to the location of the patient's wound, wherein there are no less than two groups of interconnected connectors 2 in the binding mechanism 112. The connection method of more than two groups of connectors 2 can improve the stability of the tourniquet fitting the patient's wound and can meet the needs of hemostasis of wounds like joints. The connection length between the connectors 2 can be adjusted as needed to fully and stably fix the tourniquet to the patient's body. The soft pad layer 12 on the inner side of the airbag layer 11 is provided with a protective membrane layer 122 on the cotton pad layer 121. The protective membrane layer 122 can avoid the feeling of pulling pain when untying the tourniquet.

[0025] Reference Figure 1The top of the placement layer 111 is provided with a placement opening 1111, which is located at the top center of the placement layer 111. A cavity for accommodating the inflatable airbag 3 is provided within the inner cavity of the placement layer 111. The top of the placement layer 111 is provided with perforations that penetrate the air inlet duct 31 and the air outlet duct 32. The top surface of the placement layer 111 is made of inelastic fabric, while the bottom surface of the placement layer 111 is made of elastic bandage. A fastener 1112 is provided at the placement opening 1111 to secure the fabric. Fastener 1112 is secured using Velcro or a snap fastener.

The placement layer 111 also has perforations at the top for the air inlet duct 31 and the air outlet duct 32 to pass through. The placement opening 1111 is secured with Velcro, thereby limiting and securing the inflatable airbag 3 within the placement layer 111. When inflated, the inflatable airbag 3 within the placement layer 111 can squeeze the elastic bandage below to increase and decrease pressure on the patient's wound. Furthermore, the separate design between the inflatable airbag 3 and the tourniquet body 1 allows for the reuse of the inflatable airbag 3. After each use, only the tourniquet body 1 needs to be replaced, effectively reducing the cost of using a tourniquet with an airbag.

[0026] Reference Figure 1 The binding mechanism 112 is horizontally distributed between the connectors 2, wherein the connector 2 includes an elastic connector 21 on both sides of a free end on one side and a clamping seat 22 on the other free end. The elastic connector 21 is provided with multiple claws 211 on both sides, and the clamping seat 22 is provided with a clamping hole 221 corresponding to the claws 211. The height of the clamping hole 221 is adapted to the thickness of the claw 211. The claw 211 is in the shape of a right-angled triangular prism. The two sides of the clamping hole 221 are provided with a right-angled triangular prism-shaped clamping groove 222 adapted thereto, wherein the hypotenuse of the right-angled triangular prism corresponds to the hypotenuse of the right-angled triangular prism-shaped clamping groove 222. The connector 2 in the binding mechanism 112 is fixedly connected to the base 22 at the other end through an elastic connector 21 at one end to fix the tourniquet body 1 on the patient's wound, wherein the right-angled triangular prism-shaped claws 211 on both sides of the elastic connector 21 cooperate with the right-angled triangular prism-shaped slots 222 in the hole 221. Since the oblique sides of the claws 211 correspond to the oblique sides of the slots 222, the elastic connector 21 can be directly squeezed into the base 22 for locking, which facilitates the fixation of the binding mechanism 112.

[0027] Reference Figure 1The cotton padding layer 121 has a rectangular structure and is attached to the bottom surface of the placement layer 111. The protective film layer 122 is smaller in area than the cotton padding layer 121, and the protective film layer 122 is surrounded by cotton padding layers 121. The protective film layer 122 is made of silicone. The cotton padding layer 121 in the soft padding layer 12 is attached to the bottom of the placement layer 111, which can improve the softness of the contact with the patient's wound. The protective film layer 122 is arranged on the cotton padding layer 121 to reduce the film material on the skin when the tourniquet is untied, thereby reducing the pain of pulling.

[0028] Working Principle: When using an airbag compression tourniquet, first place the uninflated inflatable airbag 3 into the placement layer 111 through the placement port 1111, and then pass the air inlet pipe 31 and the air outlet pipe 32 through the perforations at the top of the placement layer 111.
