[0031] This embodiment places the tourniquet on the distal radial artery or radial artery of the hand, and controls the expansion of the compression airbag through the airbag assembly, thereby performing compression and hemostasis at the designated location. Furthermore, the tourniquet is provided with an easily adjustable fixing assembly, which can be used to secure the tourniquet and airbag to the hand through the combination of a fixed cloth strap and a movable cloth strap. The movable cloth strap can be adjusted to conform to the shape of the hand, performing the bandaging and fixing functions, and improving the tightness of the fixation. Specific embodiments are as follows:

[0032] like Figures 1 to 5A dual-use airbag tourniquet for distal radial artery and radial artery is shown. The tourniquet comprises a tourniquet body 1, an airbag assembly, and a fixing assembly. The airbag assembly is fixedly mounted in the middle of the tourniquet body 1. The fixing assembly is disposed on the outer edge of the tourniquet body 1. The airbag assembly includes a compression bag 2 and an inflation / deflation tube 7. The compression bag 2 is mounted in the middle of the upper surface of the tourniquet body 1, with one side of the compression bag 2 connected to the inflation / deflation tube 7. The fixing assembly comprises two symmetrically arranged fixing straps 3 and a movable, removable strap 4 extending through the middle of the tourniquet body 1. When the tourniquet is applied to the distal radial artery or radial artery of the hand, the airbag assembly controls the pressure and expansion of the compression bag 2, thereby applying pressure and stopping bleeding at the designated location. Furthermore, the tourniquet is provided with an easily adjustable fixing assembly. The fixing strap 3 and the removable strap 4 cooperate to secure the tourniquet and airbag to the hand. The movable and adjustable removable strap 3 can adapt to the shape of the hand, providing a bandaging and fixation effect and enhancing the tightness of the fixation.

[0033] An air source connector 8 is provided at the end of the inflation / deflation tube 7, away from the compression bag 2. A sealing piston 9 is mounted on this connector. This connector is connected to a high-pressure source, inflating the compression bag 2 and achieving hemostasis. The sealing piston 9 maintains the stability of the bag and prevents bleeding. The sealing piston 9 is detachable and connected to the outer edge of the air source connector 8 via a connecting strap.

[0034] The compression airbag 2 is in the shape of an ellipsoid and is made of polyester fiber.

[0035] The compression bag 2 is connected to a pressure monitoring assembly, which includes a display 10, an air pressure detector 14, and an alarm light 18. The display 10 and alarm light 18 are mounted in the middle of the lower surface of the tourniquet body 1. The air pressure detector 14 is mounted inside the tourniquet body 1, and the detection end of the air pressure detector 14 is connected to the compression bag 2. By connecting the pressure monitoring assembly to the compression bag 2, the compression bag 2 can be monitored by the air pressure detector 14, and the pressure value can be displayed on the display 10. In the event of abnormal pressure, the alarm light 18 can sound an alarm, reminding staff to take timely measures to avoid hand injuries caused by excessive pressure, further improving the safety of the tourniquet. The alarm light 18 is electrically connected to the air pressure detector 14.

[0036] Two corresponding movable serrated openings 11 are formed on the tourniquet body 1, and a movable cloth belt 4 is inserted into the two movable serrated openings 11. A number of serrated bars 5 are installed on the movable cloth belt 4 and are movably connected to the movable serrated openings 11. By pulling the movable cloth belt 4, it can be moved in the movable serrated opening 11, thereby changing its length on both sides of the tourniquet body 1. Under the action of the serrated bars 5, gradual adjustment can be achieved.

[0037] The two movable serrated openings 11 are respectively equipped with limiting racks 12, which are matched with the tooth grooves formed between the limiting racks 12 and the plurality of serrated bars 5. The movable cloth belt 4 can be limited by the limiting racks 12. When the movable cloth belt 4 needs to be moved, it can be opened and the limit can be released.

[0038] The compression bag 2 is provided with a reinforcement layer 16 inside, and an antibacterial sleeve 17 on its outer surface. The reinforcement layer 16 provided inside the compression bag 2 can improve the pressure-bearing capacity of the compression bag 2 and prevent damage.

[0041] One end of the inflation and deflation air tube 7 close to the compression air bag 2 is provided with a booster pump 15, which is installed inside the tourniquet body 1. Through the booster pump 15, it is convenient to extract the air source, thereby supplying air to the compression air bag 2.

[0042] Working principle: Place the tourniquet on the distal radial artery or radial artery position of the hand, and the airbag assembly can be used to control the pressurization and expansion of the compression airbag, so as to compress and stop bleeding at the designated position. In addition, the tourniquet is provided with a fixing assembly that is easy to adjust, and the tourniquet and the airbag can be fixed on the hand by combining the fixed cloth belt and the movable cloth belt. The movable cloth belt can be adjusted to conform to the shape of the hand, play the role of bandaging and fixation, and improve the tightness of fixation. By connecting the pressure monitoring assembly of the compression airbag, the compression airbag can be monitored by the air pressure detector, and the pressure value can be displayed on the display. In the case of abnormal pressure, an alarm will be issued through the alarm light to remind the staff to deal with it in time to avoid injury to the hand caused by excessive pressure, thereby further improving the safety of the tourniquet. By setting a reinforcement layer inside the airbag, the pressure-bearing capacity of the airbag can be improved to avoid damage. By setting an antibacterial layer on the outer surface of the airbag, the antibacterial effect of the outer surface of the airbag can be improved to avoid bacterial growth affecting the hemostasis and nursing effects.
