[0027] A pneumatic hemostatic device provided in an embodiment of the present application is now described. Figure 1 and Figure 2A pneumatic hemostatic instrument comprises a shell 1, wherein an air pump group 14, a solenoid valve, an air storage tank and a PCB board are arranged in the shell 1, the solenoid valve is connected to the air storage tank, the air storage tank is connected to the air pump group 14, the air storage tank is also connected to an output socket, and the output socket is connected to a pneumatic tourniquet 21 through a tracheal output pipe 20. The air storage tank is also connected to a channel spare hole. A pressure sensor and a switching power supply module 11 are arranged on the PCB board. A display screen 3 is arranged on the front side wall of the shell 1. A power socket 12 and a channel spare hole are arranged on the rear side wall of the shell 1, and the power socket 12 is connected to a power supply through a power cord 22. The inflation pressure of the pneumatic tourniquet 21 can be automatically set and accurately controlled according to the actual physical conditions of different patients.

[0028] Specifically, two solenoid valves are provided, namely a first solenoid valve 2 and a second solenoid valve 5; the first solenoid valve 2 and the second solenoid valve 5 are connected to the display screen 3, and the on and off of the first solenoid valve 2 and the second solenoid valve 5 can be controlled by touch screen operation of the display screen 3.

[0029] There are two gas storage tanks, namely a first gas storage tank 15 and a second gas storage tank 10;

[0030] There are two channel spare holes, namely a first channel spare hole 18 and a second channel spare hole 19 .

[0031] The first solenoid valve 2 is connected to the first air tank 15, and the first air tank 15 is connected to the air pump group 14 through the first one-way valve 16; the first air tank 15 is also connected to the first channel spare hole 18; the first air tank 15 is also connected to the first port of the first three-way pipe 17, and the second port of the first three-way pipe 17 is connected to the first output socket 4, and the first output socket 4 is connected to a pneumatic tourniquet 21 through a tracheal output pipe 20, and the third port of the first three-way pipe 17 is connected to a pressure sensor.

[0032] The second solenoid valve 5 is connected to the second gas tank 10, the second gas tank 10 is connected to the air pump group 14 through the second one-way valve 9, and the second gas tank 10 is also connected to the second channel spare hole 19; the second gas tank 10 is also connected to the first port of the second three-way pipe 8, the second port of the second three-way pipe 8 is connected to the second output socket 7, the second output socket 7 is connected to another air pressure tourniquet 21 through another tracheal output pipe 20, and the third port of the second three-way pipe 10 is connected to the pressure sensor.

[0033] The switch power module 11 is electrically connected to the filter 13 , the power socket 12 , the power switch 6 and the pressure sensor respectively.

[0034] A handle 23 is provided on the top of the housing 1 for easy handling.

[0035] See also Figure 3 and Figure 4The inner side of the air pressure tourniquet 21 is provided with a first fitting portion 211, and the outer side of the air pressure tourniquet 21 is provided with a second fitting portion 212, and the first fitting portion 211 and the second fitting portion 212 can be closely fitted together.

[0036] The inner side of the pneumatic tourniquet 21 is also provided with a tourniquet three-way air inlet pipe 213 connected to the tracheal output pipe 20 , the second interface of the tourniquet three-way air inlet pipe 213 is connected to the internal pipeline of the pneumatic tourniquet 21 , and the third interface of the tourniquet three-way air inlet pipe 213 is connected to the regulating device 214 .

[0037] The tracheal output tube 20 includes a tracheal output tube 201 at the tourniquet end and a tracheal output tube 202 at the hemostat end. The tracheal output tube 201 at the tourniquet end and the tracheal output tube 202 at the hemostat end are detachably connected, so that the pneumatic tourniquet 21 can be disconnected from the hemostat and the patient can be transferred conveniently. A first magnet ring 205 is provided at the end of the tracheal output tube 201 at the tourniquet end, and a second magnet ring 206 is provided at the end of the tracheal output tube 202 at the hemostat end. The first magnet ring 205 and the second magnet ring 206 are magnetically attracted to each other. In order to further achieve the sealing performance of the two, a rubber or silicone gasket ring can be provided between the two. When the patient wearing the pneumatic tourniquet 21 needs to be transferred, the first magnet ring 205 and the second magnet ring 206 can be separated. In order to ensure the cleanliness of the inside of the tracheal output tube 201 at the tourniquet end, a third magnet block 203 with magnetic attraction can be placed on the first magnet ring 205. When not in use, the third magnet block 203 can be placed separately or directly adsorbed on the outer wall of the first magnet ring 205. For further information, see Figure 5 or Figure 6 , a groove whose curvature matches that of the first magnet ring 205 can be provided on the third magnet block 203. When the first magnet ring 205 and the second magnet ring 206 are separated, the groove of the third magnet block 203 can be fitted on the outer side of the second magnet ring 206. Since the second magnet ring 206 and the third magnet block 203 magnetically repel each other, when the third magnet block 20 and the first magnet ring 205 are attracted and connected, the repulsive force also causes the second magnet ring 206 to separate from the first magnet ring 205 more quickly. A one-way valve 204 is also provided on the tracheal output tube 201 at the tourniquet end to ensure that the air pressure tourniquet 21 only takes in air but does not let out air, thereby stabilizing the internal air pressure.

[0038] The adjusting device 214 includes a tube body 2143, and a slidable rubber ring 2141 is provided inside the tube body 2143 and is sealed with the tube body 2143. The rubber ring 2141 is connected to a sliding rod 2142. By pushing the sliding rod 2142 to move up and down, the rubber ring 2141 can slide up and down. A plurality of exhaust holes 2144 are provided on the tube body 2143 near the port. When the air pressure in the air pressure tourniquet 21 needs to be supplemented, the required air pressure can be added to the air pressure tourniquet 21 by pushing the sliding rod 2142. When the patient does not need the air pressure tourniquet to stop bleeding and needs to deflate, the remaining air in the air pressure tourniquet 21 can be discharged through the exhaust holes 2144 by pulling the sliding rod 2142. In order to prevent the rubber ring 2141 from escaping from the tube body 2143, a limit block is provided at the edge of the port of the tube body 2143. The cooperation between the sliding rod 2142 and the rubber ring 2141 enables the air pressure tourniquet 21 to be inflated and deflated, which is convenient to operate and use.

[0039] For further information, see Figure 7 and Fig. 9 An adjustable protrusion 30 is provided on the bottom wall of the housing 1. The adjustable protrusion 30 can be adjusted up and down through a threaded stud 31. The adjustable protrusion 30 is rotated according to needs to ensure the horizontality of the pneumatic hemostatic instrument.

[0040] See also Figure 1 , Figure 7 and Figure 8 In order to improve the stability of the pneumatic hemostatic instrument of the present application when placed on a relative table, a rubber pressure plate 28 is provided on the outer side of the bottom wall of the housing 1. The rubber pressure plate 28 is connected to the rubber hose 27 through the hollow tube 24. The rubber hose 27 is connected to a detachable air bag 26. A detachable air stop clamp 25 is provided on the rubber hose 27. A sealing ring 29 is provided between the hollow tube 24 and the bottom wall of the housing 1. When the rubber pressure plate 28 is pressed on the corresponding table, the handle 23 is gently pressed downward to make the disk surface of the rubber pressure plate 28 adsorbed on the table, and the air is discharged to the air bag 26 through the hollow tube 24 and the rubber hose 27. At this time, the air stop clamp 25 is tightened on the rubber hose 27 to stabilize the air pressure between the rubber pressure plate 28 and the table, thereby ensuring the stability of the placement of the pneumatic hemostatic instrument.

[0041] In order to cooperate with the adjustment of the horizontality, the outer wall of the sealing ring 29 is provided with a groove for cooperating with the bottom wall of the shell 1, an internal thread is provided on the inner wall of the sealing ring 29, and an external thread is provided on the outer wall of the hollow tube 24, so that the inner wall of the sealing ring 29 is adapted to the outer wall of the hollow tube 24, and the hollow tube 24 can move up and down.

[0042] The present application provides a pneumatic hemostatic instrument. According to the patient's transfer needs, the connection between the pneumatic hemostatic instrument and the pneumatic tourniquet can be cut off at any time. After the two are disconnected, the stability of the internal air pressure of the pneumatic tourniquet can still be maintained, so that the pneumatic tourniquet can still be kept in a pressing and hemostatic state. The operation is convenient and the structure is reasonable. Through the setting of the adjustment device, auxiliary air replenishment and air release of the pneumatic tourniquet are realized. At the same time, the present application can also improve the horizontality and stability of placement.

[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
