[0002] Patients with coronary heart disease are getting younger and younger, and there are more and more patients with multi-vessel disease. They often need multiple coronary angiography to solve the problem of vascular disease. Therefore, the patient's experience of each interventional surgery is particularly critical. The patient's comfort at each step needs to be paid attention to, especially the pain. The comfort of compression in the late stage of radial artery puncture needs to be solved in particular.

[0003] Clinically, more and more patients are undergoing coronary angiography (CAG), and most of them adopt radial artery puncture, which has small wound and fast recovery. However, the traditional balloon radial artery clamp is close to the skin with plastic (PP, PE, PVC) (the plastic raw material is a polymer, because the plastic component is not breathable, long-term pressure will cause skin discomfort, pain, blistering, ulceration, bring bad experience and pain to patients, and cause psychological discomfort and shadow. It may even affect further treatment.

[0004] A new hydrocolloid dressing balloon radial artery clamp with protective effect is now available. Utility Model Content

[0016] The beneficial effects of this application are:

[0017] 1. By setting up a hydrocolloid dressing, a hydrocolloid dressing is a dressing made by mixing elastic polymer hydrogel with synthetic rubber and adhesive. The most common gel in dressings is carboxymethyl cellulose, which can be firmly attached to the skin at the edge of the wound and can swell 12 times after absorbing exudate; it has the ability to absorb wound exudate. After absorbing exudate, the hydrophilic particles in the dressing can form a semi-solid substance similar to gel, which adheres to the base of the wound, providing and maintaining a moist environment that is conducive to wound healing; it is sticky and can form a closed wound. The closed healing environment can promote the proliferation of microvessels and the formation of granulation tissue, thereby accelerating wound healing; it can play a debridement function; on the one hand, the hydrocolloid contains endogenous enzymes that can promote the dissolution of fibrin; on the other hand, the closed environment provided by the hydrocolloid dressing is conducive to the removal of necrotic tissue by macrophages.

[0018] Second, by providing a pressing plate, a return spring, a first one-way valve, and a second one-way valve, the pressing plate can be directly pressed to inflate the airbag, thereby avoiding the unhygienic disadvantage of blowing air directly with the mouth.

[0019] 3. By setting a limit bolt and movably setting the reset spring on the limit sleeve, when the elasticity of the reset spring weakens, the limit bolt can be rotated to facilitate replacement of the reset spring. BRIEF DESCRIPTION OF THE DRAWINGS

The sub-velcro 17 is arranged on the inner side of one end of the airbag 13. The main Velcro 15 is arranged on the outer side of the other end of the airbag 13. One end of the hose 7 is connected to the airbag 13. The mounting tube 3 is connected to the other end of the hose 7. The air outlet pipe 19 is connected to the airbag 13, and a second threaded cap 20 is threadedly connected to the air outlet pipe 19.

[0036] The inflation assembly is arranged on the mounting tube 3. The inflation assembly includes a first one-way valve 6 and a second one-way valve 9. The mounting tube 3 is connected with a second connecting tube 8, and the second one-way valve 9 is arranged in the second connecting tube 8. The second connecting tube 8 is located above the first connecting tube 5. The direction of the second one-way valve 9 faces the mounting tube 3, the first connecting tube 5 is fixedly connected in the hose 7, and the first one-way valve 6 is arranged in the first connecting tube 5, and the direction of the first one-way valve 6 is away from the mounting tube 3, and a piston assembly is arranged in the mounting tube 3.

[0037] The piston assembly includes a sealing plate 11, which is slidably mounted in the mounting tube 3, and a connecting rod 14 is fixedly connected to the top of the sealing plate 11, and a pressing plate 21 is fixedly connected to the top of the connecting rod 14, and the pressing plate 21 facilitates the movement of the sealing plate 11. A reset assembly is arranged in the mounting tube 3. The reset assembly includes a reset spring 4, and a mounting seat 18 is fixedly connected in the mounting tube 3, and the mounting seat 18 is annular. A limiting sleeve 10 is fixedly connected to the mounting seat 18, and the reset spring 4 is movably arranged in the limiting sleeve 10, and the limiting spring abuts against the piston. The reset spring 4 and the limiting sleeve 10 are respectively set to two, and the two groups of reset springs 4 and limiting sleeves 10 are symmetrically arranged. A limiting bolt 12 is threadedly connected to the mounting tube 3, and the limiting bolt 12 corresponds to the sealing plate 11, and the limiting bolt 12 is set to two, and the two limiting bolts 12 are symmetrically arranged.

[0038] The top of the mounting tube 3 is threadedly connected with a first threaded cover 1, and the first threaded cover 1 is provided with anti-skid patterns 2. The first threaded cover 1 plays a role in preventing dust, and the anti-skid patterns 2 play a role in increasing friction.

[0039] Working process: When in use, the hydrocolloid dressing 16 is cut along the midline to the center position, and then a circular hole with a diameter of 0.8 cm is opened at the center position. The circular hole is a reserved hole for the puncture site. Then the hydrocolloid dressing 16 is attached to the radial artery puncture site. Under the action of the hydrocolloid dressing 16, it has the ability to absorb wound exudate. After absorbing the exudate, the hydrophilic particles in the dressing can form a semi-solid substance similar to gel, which adheres to the base of the wound, providing and maintaining a moist environment that is conducive to wound healing. It is sticky and can form a closed wound. The closed healing environment can promote the proliferation of microvessels and the formation of granulation tissue, thereby accelerating wound healing and playing a debridement function. On the one hand, the hydrocolloid contains endogenous enzymes that can promote the dissolution of fibrin. On the other hand, the closed environment provided by the hydrocolloid dressing 16 is conducive to the removal of necrotic tissue by macrophages. Then the airbag 13 is put on the arm.

[0040] Then the airbag 13 is wrapped around the puncture site, and under the action of the sub-Velcro 17 and the female Velcro 15, the two ends of the airbag 13 are fixed, and then the first threaded cover 1 can be opened, and then the pressing plate 21 can be pressed. When the pressing plate 21 descends, under the action of the connecting rod 14, the sealing plate 11 is driven to descend, and under the action of the first one-way valve 6 and the second one-way valve 9, the gas enters the hose 7, and finally the gas enters the airbag 13, so that the airbag 13 gradually swells. When the pressing plate 21 is no longer pressed, under the action of the return spring 4, the sealing plate 11 rises, and under the action of the first one-way valve 6 and the second one-way valve 9, the sealing plate 11 rises, allowing external gas to enter through the second connecting pipe. Repeat this action, and finally the airbag 13 is opened. By setting the pressing plate 21, the staff can avoid blowing with their mouths, which is more laborious and unhygienic. When the return spring 4 has been used for a long time and has poor elasticity, the limit bolt 12 can be rotated and removed, and then the sealing plate 11, the connecting rod 14 and the pressing plate 21 can be taken out. Since the return spring 4 is movably arranged on the limit sleeve 10, the return spring 4 can be easily taken out.
