Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, more particularly, it relates to a compression device that can be autonomously deflated after a transradial intervention. BACKGROUND

[0002] More than 90% of coronary angiography interventions are currently performed through the radial artery of the upper limb. Compared with femoral artery puncture, it is more convenient to stop bleeding, patients can get out of bed early, the damage is small, the recovery is fast, the hospital stay is short, and the peripheral vascular complications are less. After the transradial intervention puncture is completed, the surgeon will inflate and pressurize the patient to stop bleeding. The doctor needs to deflate the patient 3 times to gradually reduce the pressure, with an interval of 2 hours each time. Studies have shown that the incidence of coronary artery problems in people of all ages is very high, and the daily operation volume in the ward is large. Patients returning to the ward need to be deflated 3 times, which greatly increases the workload of doctors. Moreover, the deflation of the patient is not timely due to the doctor's need to deal with other patient problems, the patient's pain time is prolonged, and the doctor-patient relationship is deteriorated. Therefore, there is an urgent need for a radial artery compression device that can be autonomously deflated by the patient, enhancing the patient's autonomy, improving the patient's comfort, improving the doctor's work efficiency, and improving the doctor-patient relationship. CONTENT OF THE INVENTION

[0003] The purpose of the present application is to provide a compression device that can be autonomously deflated after a transradial intervention. This device can be used to compress the patient's wrist after a transradial intervention. After the doctor injects gas into the device using a syringe, the patient can complete the deflation process by himself by pressing the gas nozzle cap in sequence until the deflation is complete. If an individual patient bleeds after deflation, 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 autonomously deflated after a transradial intervention, comprising:

[0005] A wrist strap for fixing the compression device to the patient's wrist;

[0006] A first inflatable air bag is provided on the wrist strap, and the first inflatable air bag is provided with an inflation hole and a first deflation valve;

[0007] A second inflatable air bag is in communication with the first inflatable air bag through a gas-tight check valve, which allows gas to flow from the first inflatable air bag to the second inflatable air bag in one direction. The second inflatable air bag is provided with a second deflation valve;

[0008] A third inflatable air bag is in communication with the first inflatable air bag through a gas-tight check valve, which allows gas to flow from the first inflatable air bag to the third inflatable air bag in one direction. The third inflatable air bag 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 unidirectionally from the first inflatable airbag to the fourth inflatable airbag. The fourth inflatable airbag is equipped with a fourth deflation valve.

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

[0011] Furthermore, multiple through holes are provided.

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

[0013] Furthermore, the first inflatable airbag is a 12cm piece made of smooth, transparent rubber. 3 Volumetric inflatable airbag.

[0014] Furthermore, the second, third, and fourth inflatable airbags are all 2cm in size and made of smooth, transparent rubber. 3 A crescent-shaped inflatable airbag with a volume of [missing information].

[0015] Furthermore, the second, third, and fourth vent valves are all gas nozzle cap structures, which can release the gas inside the airbag by pressing.

[0016] Furthermore, the second, third, and fourth vent valves are set to different colors.

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

[0018] 1. This device allows patients to release air independently, reducing patient pain, optimizing doctors' work efficiency, and reducing doctor-patient conflicts.

[0019] 2. Currently available compression devices compress the radial artery puncture site while also compressing the bones in the patient's wrist, which can cause postoperative discomfort, often manifested as pain. In some cases, the pain can even trigger a vagus nerve reflex. The crescent-shaped design of the inflatable balloon can effectively compress only the puncture site. In addition to compressing the puncture site, the wristband is made of liquid silicone material, which can effectively improve patient comfort.

[0020] 3. Studies have shown that the inflation pressure of the balloon after radial artery intervention is generally 13-15 ml, and at most not exceeding 18 ml. Therefore, this product is designed with an 18 ml inflation balloon. The inflation port uses an airtight check valve design, allowing for inflation at every 2cm interval. 3 Once the crescent-shaped inflatable airbag is full, the gas is injected in the same direction without backflow, ultimately flowing to a depth of 12cm. 3The inflatable bladder is filled with air. If bleeding occurs after the air is deflated, the doctor can be notified to re-inflate the bladder to maintain pressure and stop the bleeding. The patient can release 2ml of air autonomously each time by removing the three valve caps sequentially every two hours, eliminating the need for further deflation by the doctor.

[0024] The structure and effects of this application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the invention, not the entire structure.

[0025] Example

[0026] This application discloses a compression device that allows for spontaneous deflation after radial artery intervention, referring to... 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 a continuous strip structure, comprising a first end and a second end. The first end has a buckle structure 11, and the second end has multiple through holes 12 for the buckle structure 11 to engage. Except for the buckle, the rest of the wristband 1 is made of liquid silicone, which significantly reduces pressure on the patient's wrist and improves patient comfort. The first inflatable airbag 2 is mounted on the wristband 1 and has an inflation port 3 and a first deflation valve 4. During use, air can be injected into the airbag through the inflation port 3 using an inflation syringe. 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 via an airtight check valve 13. The airtight check valve 13 allows gas to flow unidirectionally from the first inflatable airbag 2 to the second inflatable airbag 5, the third inflatable airbag 7, and the fourth inflatable airbag 9. The second inflatable airbag 5, the third inflatable airbag 7, and the fourth inflatable airbag 9 are respectively equipped 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 balloon after radial artery intervention is generally 13-15 ml, and at most does not exceed 18 ml. Therefore, in this embodiment, the first inflatable balloon 2 is set as a 12cm balloon made of smooth, transparent rubber. 3 The volumetric inflatable airbags, including the second airbag 5, the third airbag 7, and the fourth airbag 9, are all made of smooth, transparent rubber and are 2cm thick. 3 A crescent-shaped inflatable airbag with a volume of [missing information].

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

[0029] The implementation process of this application is as follows: This device is used on patients who require compression hemostasis after radial artery intervention and are capable of spontaneous deflation. After radial artery intervention, the device is applied to the patient's wrist. The compression balloon is aligned with the radial artery puncture site, and the buckle is fixed to the through hole 12. An appropriate amount of gas is injected into the syringe through the inflation port 3. The gas will pass through the three airtight check valves 13 in a forward direction for 2cm. 3 The crescent-shaped inflatable airbag was finally inflated to 12cm. 3 The airbag is inflated. When the patient returns to the ward two hours post-surgery and needs to deflate, press the second deflation valve 6 first, then the third deflation valve 8 and the fourth deflation valve 10 in sequence. Due to the check valve, only 2cm of air can be deflated. 3 The crescent-shaped inflatable bladder is filled with gas. Once deflation is complete, the valve cap automatically springs back. In rare cases, if bleeding occurs after deflation, simply inject more gas into inflation port 3 using a syringe to repressurize the device. When removing the compressor, a syringe can be used to remove the 12cm... 3 Once the airbag is completely deflated, release the buckle.

[0030] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
