Description

Technical Field

[0001] This utility model relates to a radial artery graded pressure hemostasis device. Background Technology

[0002] The radial artery is an artery. Due to the high pressure inside the blood vessel, it is prone to bleeding after radial artery puncture. In general, compression hemostasis is required to prevent hematoma from forming at the puncture site.

[0003] The existing pressure hemostats have the following defects: (1) In order to ensure effectiveness and safety, the pressure intensity must be adjusted by medical staff, and patients lack the basis for self-adjustment, so patients are usually not allowed to adjust it themselves; (2) The pressure intensity is based on experience and feel, and there is a lack of visual data display; (3) It is not easy to adjust the pressure intensity accurately and linearly, and the controllability is poor, which leads to the situation of excessive or insufficient pressure.

[0020] See Figure 1-3In one specific embodiment of this utility model, the structure includes a pressurizer and straps 1 connected to both sides of the pressurizer. The pressurizer includes a core 2 and an elastic airbag 3 covering the outer surface of the core 2. The airbag 3 has an air inlet 4 and an exhaust outlet 5. The air inlet 4 is equipped with an inflation mechanism. The core 2 is fitted with a graded adjustment rod 6 corresponding to the exhaust outlet 5. The outer port of the exhaust outlet 5 is equipped with a sealing cap 7. A pressure sensor 8 is provided in the interlayer on the side of the airbag 3 near the body. The pressure signal of the pressure sensor 8 is transmitted to the display screen for display.

[0021] The adjustable lever 6 shown is an electric actuator. The lever 6 gradually thickens from its end inwards, and its extension length is controlled wirelessly by the length adjuster 9. The length adjuster 9 is equipped with extension and shortening buttons. The length adjuster 9 is held and used by medical personnel. When the adjustable lever 9 is shortened to its shortest length, the gas inside the airbag 3 can be completely released.

[0022] The exhaust port 5 shown is provided with an elastic hoop 16, and the graded adjustment rod 6 is provided with a sealing ring 17 opposite to the hoop 16. When the hoop 16 and the sealing ring 17 abut against each other, the airtightness and durability of the exhaust port 5 can be improved, and the graded adjustment rod 6 can be prevented from bursting the exhaust port 5.

[0023] The strap 1 shown is adjusted in length and secured by buckle 18.

[0024] The core 2 shown is cylindrical or elliptical, and the airbag 3 covers the curved surface of the core 2. The display screen shown is located at the end of the core 2. The curved surface of the pressurizer contacts the patient's body, which can reduce discomfort during the compression process.

[0025] The air inlet 4 shown is a one-way valve that can only deliver gas from the outside to the airbag 3. The inflation mechanism shown includes a piston cylinder 10 connected to the air inlet 4 and a piston rod 11 that cooperates with the piston cylinder 10. An air exchange valve 12 is provided at the bottom of the side wall of the piston cylinder 10. When the piston rod 11 is pressed down, the air exchange valve 12 is closed. When the piston rod 11 is pulled up, the air exchange valve 12 is opened. The ratio of the inner diameter of the piston cylinder 10 to the stroke of the piston rod 11 is greater than or equal to 2.

[0026] The ventilation valve 12 is a flap valve structure.

[0027] The piston cylinder 10 is externally connected to a threaded cylinder 13. The threaded cylinder 13 is rotatably connected to the piston rod 11 via a connecting rod 14 and a ball bearing 15. The ball bearing 15 includes a ball head fixed to the lower end of the connecting rod 14, a ball cavity disposed within the piston rod 11, and balls disposed between the inner walls of the ball head and the ball cavity. The rotation of the threaded cylinder 13 controls the extension and retraction of the piston rod 11, thereby controlling the expansion degree of the airbag 3, providing strong controllability and precise adjustment. The threaded cylinder 13 can rise or fall during rotation. Because the connecting rod 14 and the ball bearing 15 only transmit lifting and lowering motion without transmitting rotational motion, the piston rod 11 only rises and falls without rotating, improving the sealing between the piston rod 11 and the piston cylinder 10.

[0028] The working principle of this utility model is as follows: the pressure device is initially fixed in the compression area by the strap 1, the inflation degree of the airbag 3 is controlled by the inflation mechanism by rotating the threaded cylinder 13, and the pressure intensity is displayed by the pressure sensor 8. This adjustment method is smooth, precise and linear, and visually controls the pressure of hemostasis at the radial artery puncture site.

[0029] Limited self-adjustment by the patient: When the patient feels discomfort at the pressure point, they can open the sealing cap 7 of the vent 5, causing the airbag 3 to deflate and shrink. Once the tiered adjustment rod 6 is inserted and the vent 5 is sealed, the airbag 3 stops deflating and maintains the reduced pressure intensity. This allows the patient to alleviate discomfort through limited self-adjustment. The length of the tiered adjustment rod 6, set by the length adjuster 9, is obtained through pre-testing. The requirement is that even with the sealing cap 7 open, the minimum pressure effect of the airbag 3 can be guaranteed, avoiding the risk of hematoma at the puncture site caused by unrestricted self-adjustment by the patient.

[0030] Medical staff can make adjustments to the maximum extent possible: If the patient still feels uncomfortable after self-adjustment, medical staff can observe and shorten the length of the graded adjustment rod 6 to further reduce the pressure within a safe and effective range.

[0031] After applying pressure to stop the bleeding, remove the bandage 1.

[0032] The above description is only presented as a feasible technical solution of this utility model and is not intended as a single limitation on the technical solution itself.
