Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an airbag-type radial artery compressor and a pressure control method thereof. Background Art

[0002] In modern medicine, interventional therapy via radial artery puncture has become a widely used and highly advantageous treatment method. Its significant advantages, such as minimal trauma, rapid postoperative recovery, and the absence of prolonged patient restraints, significantly enhance the patient experience and recovery efficiency, earning it widespread favor among physicians and patients. However, with the widespread adoption of this technique, the issue of hemostasis at the radial artery puncture site has become increasingly prominent, becoming a critical factor affecting treatment efficacy and patient prognosis.

[0003] Existing airbag compressors still have major defects in pressure regulation. For example, some products rely entirely on medical staff to manually perform inflation and deflation operations. This manual operation cannot accurately guarantee the amount of inflation and deflation each time, resulting in imprecise pressure regulation. In actual clinical applications, this may make it impossible to timely and accurately adjust the compression pressure to the optimal state that can effectively stop bleeding and ensure vascular patency, increasing the risk of complications such as radial artery occlusion, and also affecting the patient's comfort and recovery process. To this end, we propose an airbag radial artery compressor and its pressure control method. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide an airbag radial artery compressor and a pressure control method thereof, which have the advantage of precise pressure control and solve the major defects of existing airbag compressors in pressure regulation. For example, some products rely entirely on medical staff to manually perform inflation and deflation operations. This manual operation method cannot accurately guarantee the inflation and deflation volume each time, resulting in inaccurate pressure regulation. In actual clinical applications, this may make it impossible to timely and accurately adjust the compression pressure to the optimal state that can effectively stop bleeding and ensure blood vessel patency, increasing the risk of complications such as radial artery occlusion, and also affecting the patient's comfort and recovery process.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an airbag radial artery compressor, comprising a fixing plate, a shell fixedly connected to the central axis of the top of the fixing plate, a box fixedly connected to the right side of the shell, a motor fixedly connected to the top of the box, a reciprocating screw fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to the surface of the reciprocating screw, a connecting frame fixedly connected to the top of the threaded sleeve, a sealing plate fixedly connected to one side of the connecting frame, a hollow block fixedly connected to the central axis of the top left side of the shell, and the inner wall of the hollow block is provided with A sealing block, the bottom of the sealing block is fixedly connected to a tension sensor, and the bottom of the tension sensor is fixedly connected to an adjustment frame, the bottom of the adjustment frame is fixedly connected to an adjustment plate, the top of the adjustment plate is fixedly connected to a first spring, the top of the first spring is fixedly connected to the hollow block, the central axis of the bottom of the hollow block is connected to the shell through an air guide pipe, the front end of the left bottom of the shell is connected to a first one-way valve, the bottom of the shell is connected to a second one-way valve, the bottom of the second one-way valve is connected to an airbag bag, and the rear end of the left bottom of the airbag bag is connected to a solenoid valve.

[0006] Preferably, the bottom of the airbag bag is fixedly connected to an adjusting block, a tourniquet is provided at the bottom of the adjusting block, connecting plates are fixedly connected on both sides of the tourniquet, a hollow shell is plugged into one side of the connecting plate, a second spring is fixedly connected to the top of the inner cavity of the hollow shell, a pressure plate is fixedly connected to one side of the second spring, a latch is fixedly connected to the bottom of the pressure plate, the surface of the latch is plugged into the connecting plate, a cloth belt is fixedly connected to one side of the pressure plate, and a pull block is fixedly connected to one side of the cloth belt.

[0007] Preferably, a distribution box is fixedly connected to the back of the shell, a battery is fixedly connected to the bottom of the inner cavity of the distribution box, and a PLC controller is fixedly connected to the rear side of the distribution box.

[0008] Preferably, the inner cavity of the threaded sleeve is slidably connected to a cylinder, and the top of the cylinder is fixedly connected to the box body.

[0009] Preferably, circular holes are provided on the front and rear sides of the bottom of the inner cavity of the hollow block, and a sealing ring is fixedly connected to the inner cavity of the circular hole.

[0010] Preferably, one side of the airbag is fixedly connected to a bracket, and one side of the bracket is fixedly connected to a fixing plate.

[0011] Preferably, the inner cavity of the pressure plate is slidably connected to a prism, and the top of the prism is fixedly connected to the hollow shell.

[0012] Preferably, one side of the cloth belt contacts a guide roller, and the rear side of the guide roller is movably connected to the hollow shell through a bearing.

[0013] Preferably, a strap is movably connected to one side of the fixing plate, and air guide holes are provided on the tops of the shell and the hollow block.

[0014] A method for regulating pressure of an airbag radial artery compressor comprises the following steps:

[0015] A. First, medical staff set the tension value through the PLC controller. When the radial artery puncture point needs to be compressed to stop bleeding, the motor is started through the PLC controller. The motor drives the reciprocating screw to rotate. Since the threaded sleeve is threadedly connected to the reciprocating screw, the threaded sleeve can only move linearly along its axis when the reciprocating screw rotates. As the threaded sleeve moves, the connecting frame drives the sealing plate to move. During the rising process of the sealing plate, the external gas is sucked in through the first one-way valve. During the descending process of the sealing plate, the gas is discharged into the airbag cavity through the second one-way valve. As the gas in the airbag cavity increases, the compression force is increased.

[0016] B. At the same time, gas will enter the inner cavity of the hollow block through the air guide tube. As the gas in the inner cavity of the hollow block increases, the sealing block will move, and the sealing block will drive the tension sensor to move. Through the cooperation of the adjustment frame, the first spring and the adjustment plate, the tension sensor detects the increase in tension value. When the tension value is detected to be the same as the set value, the motor will stop working and the inflation work will be completed. When the pressure value needs to be reduced, the solenoid valve will be controlled to open to discharge the gas in the inner cavity of the airbag, thereby achieving the adjustment effect;

[0017] C. After using the compressor, pull the pull block outward by hand. The pull block drives the cloth belt to move, the cloth belt drives the pressure plate to move, and the pressure plate drives the pin to move, so that the pin is away from the connecting plate. Then move the connecting plate forward to separate the connecting plate from the hollow shell. The connecting plate will drive the tourniquet away from the adjusting block, making it easier to replace the tourniquet.

[0018] Compared with the prior art, the present invention provides an airbag radial artery compressor and a pressure control method thereof, which has the following beneficial effects:

[0019] The present invention uses a PLC controller linked with a tension sensor to accurately preset and monitor pressure in real time, automatically adjust the inflation volume, avoid complications caused by improper pressure, and ensure patient safety. The automated control design simplifies the operating process, reduces the workload of medical staff, and greatly improves the efficiency of postoperative hemostasis. The sealing plate, one-way valve, solenoid valve, first spring and other components work together to ensure stable pressure output and prevent secondary damage caused by fluctuations.

[0039] A method for regulating pressure of an airbag radial artery compressor comprises the following steps:

[0040] A. First, the medical staff sets the tension value through the PLC controller 31. When the radial artery puncture point needs to be compressed to stop bleeding, the motor 4 is started through the PLC controller 31. The motor 4 drives the reciprocating screw 5 to rotate. Since the threaded sleeve 6 is threadedly connected to the reciprocating screw 5, the threaded sleeve 6 can only move linearly along its axis when the reciprocating screw 5 rotates. As the threaded sleeve 6 moves, the connecting frame 7 drives the sealing plate 8 to move. During the rising process of the sealing plate 8, the external gas is sucked in through the first one-way valve 15. During the descending process of the sealing plate 8, the gas is discharged into the inner cavity of the airbag bag 17 through the second one-way valve 16. As the gas in the inner cavity of the airbag bag 17 increases, the compression force is increased.

[0041] B. At the same time, gas enters the inner cavity of the hollow block 9 through the air guide tube 14. As the gas in the inner cavity of the hollow block 9 increases, the sealing block 10 moves, and the sealing block 10 drives the tension sensor to move. Through the cooperation of the adjustment frame 11, the first spring 13 and the adjustment plate 12, the tension sensor detects an increase in the tension value. When the tension value is detected to be the same as the set value, the motor 4 stops working, completing the inflation work. When the pressure value needs to be reduced, the solenoid valve 33 is controlled to open, and the gas in the inner cavity of the airbag 17 is discharged, thereby achieving the regulation effect;

[0042] C. After using the compressor, pull the pull block 27 outward by hand, the pull block 27 drives the cloth belt 26 to move, the cloth belt 26 drives the pressure plate 24 to move, and the pressure plate 24 drives the latch 25 to move, so that the latch 25 is away from the connecting plate 21, and then move the connecting plate 21 to the front side to separate the connecting plate 21 from the hollow shell 22. The connecting plate 21 will drive the tourniquet 20 away from the adjusting block 19, making it convenient to replace the tourniquet 20.
