Description

Technical Field

[0001] The present application relates to the field of medical devices, and more specifically, to a compression device that can deflate autonomously after a transradial artery intervention. Background Art

[0002] At present, more than 90% of coronary angiography interventional treatments are often performed through puncture of the radial artery of the upper limb. Compared with femoral artery puncture for hemostasis, it is more convenient, patients can get out of bed early, with less damage, faster recovery, shorter hospitalization time, and fewer peripheral vascular complications. After the puncture of radial artery interventional treatment, the surgeon will inflate and pressurize it to stop bleeding. After the patient returns to the ward after surgery, the doctor needs to deflate it three times to gradually reduce the pressure, with an interval of two hours each time. Studies have reported that the incidence of coronary problems in people of all ages is extremely high, and the average daily number of surgeries in the ward is large. After returning to the ward, patients need to deflate three times, which greatly increases the workload of doctors. In addition, doctors often need to deal with other patients' problems during deflation, which leads to delayed deflation of patients after surgery, prolonged pain time, and increased conflicts between doctors and patients. Therefore, there is an urgent need for a radial artery compression device that can be used by patients to deflate autonomously, enhance patient autonomy, improve patient comfort, improve doctor work efficiency, and enhance doctor-patient relationship. Summary of the invention

[0003] The invention of this application aims to provide a compression device that can be deflated autonomously after radial artery intervention. This device can be used to compress the patient's wrist after radial artery intervention. After the doctor injects gas with a syringe, the patient can deflate the gas three times by himself. He only needs to press the gas nozzle cap in sequence until the deflation is completed. The gas nozzle cap will automatically rebound when he lets go. If bleeding occurs after deflation in some patients, the doctor can be notified to inject gas from the inflation hole to reapply pressure.

[0004] The present application provides a compression device that can be deflated autonomously after transradial artery intervention, comprising:

[0005] A wristband, the wristband is used to fix the compression device on the patient's wrist;

[0006] A first inflatable airbag, arranged on the wristband, wherein the first inflatable airbag is provided with an inflation hole and a first deflation valve;

[0007] a second inflatable airbag, connected to the first inflatable airbag through an airtight check valve, the airtight check valve allows gas to flow from the first inflatable airbag to the second inflatable airbag in one direction, and a second deflation valve is provided on the second inflatable airbag;

[0008] a third inflatable airbag, connected to the first inflatable airbag through an airtight check valve, the airtight check valve allows gas to flow from the first inflatable airbag to the third inflatable airbag in one direction, and the third inflatable airbag is provided with a third deflation valve; and

[0009] The fourth inflatable airbag is connected to the first inflatable airbag through an airtight check valve. The airtight check valve allows gas to flow from the first inflatable airbag to the fourth inflatable airbag in one direction. The fourth inflatable airbag is provided with a fourth deflation valve.

[0010] Furthermore, the wristband includes a first end and a second end connected end to end, the first end is provided with a buckle structure, and the second end is provided with a through hole for the buckle to be engaged.

[0011] Furthermore, a plurality of through holes are provided.

[0012] Furthermore, the wristband is a liquid silicone wristband.

[0013] Furthermore, the first inflatable airbag is made of smooth transparent rubber material and has a thickness of 12 cm. 3 Volume inflatable airbag.

[0014] Furthermore, the second inflatable airbag, the third inflatable airbag and the fourth inflatable airbag are all made of smooth transparent rubber and are 2 cm thick. 3 Volume crescent-shaped inflatable airbag.

[0015] Furthermore, the second air release valve, the third air release valve and the fourth air release valve are all air nozzle cap structures, and the gas in the airbag can be released by pressing.

[0016] Furthermore, the second air release valve, the third air release valve and the fourth air release valve are set to different colors.

[0017] In summary, this application has the following beneficial effects:

[0018] 1. The device can enable patients to deflate autonomously, relieve patients' pain, optimize doctors' work efficiency, and reduce conflicts between doctors and patients.

[0019] 2. The existing compressor compresses the patient's radial artery puncture point while also compressing the patient's wrist bones, which can cause postoperative discomfort in patients, often manifested as pain. In worse cases, vagus nerve reflex occurs due to pain. The crescent-shaped design of the inflatable airbag can effectively compress only the puncture point. In addition to the compression point, the liquid silicone wristband material is used to effectively improve the patient's comfort.

[0020] 3. Studies have shown that the inflation pressure of the balloon after radial artery intervention is generally 13-15ml, and no more than 18ml, so this product is designed as an 18ml inflation balloon. The inflation hole adopts an airtight check valve design, which can be opened at every 2cm 3 After the crescent-shaped inflatable airbag is filled with gas, the gas is injected in the same direction without reverse backflow, and finally to 12cm 3The volume inflatable airbag is inflated with air. When bleeding occurs after the patient deflates, the doctor can be notified to re-inflate the inflation hole to increase pressure and stop bleeding. The patient can deflate 2ml of air each time by undoing the three air nozzle caps every two hours, without the need for a doctor to deflate the air again. BRIEF DESCRIPTION OF THE DRAWINGS

It is to be understood that the specific embodiments described herein are only used to explain the invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention rather than the entire structure are shown in the accompanying drawings.

[0025] Example

[0026] The present application discloses a compression device capable of self-deflation after radial artery intervention. Figure 1 The compression device includes a wristband 1, a first inflatable airbag 2, a second inflatable airbag 5, a third inflatable airbag 7 and a fourth inflatable airbag 9. The wristband 1 is configured as a band-shaped structure connected end to end, which includes a first end and a second end. The first end is provided with a buckle structure 11, and the second end is provided with a plurality of through holes 12 for the buckle structure 11 to be inserted. Except for the buckle, the other parts of the wristband 1 are all made of liquid silicone material. Such a configuration greatly reduces the compression of the wristband 1 on the patient's wrist and improves the patient's comfort. The first inflatable airbag 2 is arranged on the wristband 1, and the first inflatable airbag 2 is provided with an inflation hole 3 and a first deflation valve 4. When in use, an inflation syringe can be used to inject air into the airbag from the inflation hole 3. The second inflatable airbag 5, the third inflatable airbag 7 and the fourth inflatable airbag 9 are all connected to the first inflatable airbag 2 through the airtight check valve 13, and the airtight check valve 13 allows the gas to flow from the first inflatable airbag 2 to the second inflatable airbag 5, the third inflatable airbag 7 and the fourth inflatable airbag 9 in one direction. The second inflatable airbag 5, the third inflatable airbag 7 and the fourth inflatable airbag 9 are respectively provided with a second deflation valve 6, a third deflation valve 8 and a fourth deflation valve 10.

[0027] Studies have shown that the inflation pressure of the airbag after radial artery intervention is generally 13-15 ml, and does not exceed 18 ml at most. Therefore, in this embodiment, the first inflatable airbag 2 is set to be a 12 cm thick smooth transparent rubber material. 3 The second inflatable airbag 5, the third inflatable airbag 7 and the fourth inflatable airbag 9 are all set to 2cm of smooth transparent rubber material. 3 Volume crescent-shaped inflatable airbag.

[0028] Furthermore, in this embodiment, the second deflation valve 6, the third deflation valve 8 and the fourth deflation valve 10 are all gas nozzle cap structures, and the gas in the airbag can be released by pressing. To facilitate patient differentiation, the second deflation valve 6, the third deflation valve 8 and the fourth deflation valve 10 are set in different colors. For example, in this embodiment, the second deflation valve 6, the third deflation valve 8 and the fourth deflation valve 10 are respectively set in red, yellow and green gas nozzle caps.

[0029] The implementation process of this application is as follows: the device is used for patients who need compression to stop bleeding after radial artery intervention and can deflate autonomously. After radial artery intervention, the device is pressed on the patient's wrist, the compression airbag is aligned with the patient's radial artery puncture point, the buckle is fixed to the through hole 12, and the syringe is filled with an appropriate amount of gas through the inflation hole 3. The gas will pass through the three airtight check valves 13 and pass through the 2cm 3 The volume of the crescent-shaped inflatable airbag is finally inflated to 12cm 3 When the patient returns to the ward after surgery and needs to deflate the air two hours later, the second deflation valve 6 is pressed for the first time, and the third deflation valve 8 and the fourth deflation valve 10 are pressed twice in sequence. Due to the function of the check valve, only the 2 cm can be released. 3 The gas in the crescent-shaped inflatable airbag is deflated and the air nozzle cap automatically rebounds. If bleeding occurs after deflation in some patients, use a syringe to inject gas into the inflation hole 3 to increase pressure. When removing the compressor, use a syringe to inject 12cm 3 After the gas in the airbag is exhausted, release the buckle.
