Description

TECHNICAL FIELD

[0001] The utility model relates to a hemostat, especially to a radial artery hemostat capable of simultaneously compressing the same side ulnar artery. BACKGROUND

[0002] Transradial access (TRA) is one of the most common accesses in interventional therapy. In the aspect of coronary intervention, the European Society of Cardiology suggests that transradial access should be used as the IA level indication for patients with acute coronary syndrome who receive interventional therapy. Similarly, the American Heart Association proposes that transradial access should be the default access for patients with acute coronary syndrome in the United States. At the same time, with the understanding of transradial access, more and more peripheral interventional therapies in the world begin to use TRA. In China, more and more interventional therapy centers begin to explore TRA in the aspects of hepatic arterial chemoembolization, hepatic arterial infusion chemotherapy, visceral aneurysm, interventional therapy for gynecological diseases, and gradually accumulate the clinical application experience of TRA in peripheral interventional therapy. TRA is gradually applied widely. Although compared with the traditional femoral artery access, transradial access can reduce the complications of the puncture point of patients, mortality, economic burden, shorten the hospitalization time, and increase the comfort of patients, but due to the fact that the radial artery is relatively thin, radial artery occlusion (RAO) is very likely to occur after puncture. RAO is the most common complication after transradial puncture catheterization, and its incidence is about 1% to 33%, which has an important impact on the treatment and quality of life of patients. On the one hand, after the occurrence of RAO, the patient loses the opportunity to perform interventional surgery through the same side radial artery in the future, such as the case of acute coronary syndrome patients who may not be able to use the radial artery for surgery when they are transferred for coronary artery bypass surgery; hepatic arterial chemoembolization, hepatic arterial infusion chemotherapy, etc. are periodic tumor interventional therapy methods, and after the occurrence of RAO, the patient cannot perform anti-tumor treatment through the radial artery. On the other hand, due to radial artery occlusion, some patients may have symptoms of hand ischemia, such as pain, numbness and limited activity, which affects the body function and quality of life. Therefore, the prevention of RAO is very important.

[0003] The appropriate radial artery compression hemostasis method and process is an important link to reduce the incidence of RAO. The Best Practices for Prevention of Radial Artery Occlusion After Transradial Diagnostic Angiography and Interventional Procedures - An International Consensus suggests that the same side ulnar artery should be compressed at the same time when the radial artery is compressed for hemostasis, so as to prevent the occurrence of RAO. In addition, after the occurrence of RAO, early compression of the same side ulnar artery can improve the recanalization rate of the radial artery. The guidelines point out that the lack of a special device for radial artery-ulnar artery double compression is one of the obstacles to using this simple and effective technique to prevent RAO.

[0004] The radial artery hemostat in the prior art only has the function of pressing the radial artery to stop bleeding, and the comfort is improved by improving the material of the pressor, such as the patent with the application number 202320558621.6 which increases the functions of intelligent pressure detection and automatic pressure reduction to increase the patency of the radial artery, and the patents with the application numbers 202221950290.2 and 202211381276.X which further improve the hemostatic capacity of the radial artery hemostat. However, the effect of these in preventing radial artery occlusion is far from enough. And there is no radial artery hemostat that can press the ulnar artery on the same side at present in China, neither related products nor related patents. Content of the utility model

[0005] The radial artery hemostat provided by the utility model can press the radial artery and the ulnar artery on the same side at the same time to overcome the defects of the prior art.

[0006] In order to solve the above technical problems, the utility model provides the following technical scheme:

[0007] The utility model discloses a radial artery hemostat that can press the ulnar artery on the same side simultaneously, which is used to overcome the defects of the prior art that the radial artery hemostat cannot press the radial artery and the ulnar artery on the same side at the same time.

[0008] Further, the radial artery side big air bag is connected with the air guide pipe A, the radial artery side small air bag is connected with the air guide pipe B, the air guide pipe A and the air guide pipe B are combined into a total air guide pipe, and the total air guide pipe is connected with the one-way valve A.

[0009] Further, the inflation device inflates the radial artery side big air bag and the radial artery side small air bag at the same time through the one-way valve A, the total air guide pipe, the air guide pipe A and the air guide pipe B, and the directional extrusion of the radial artery side big air bag and the radial artery side small air bag can press at a fixed point to realize more accurate compression hemostasis of the radial artery.

[0010] Further, the ulnar artery side air bag is connected with the air guide pipe C, the air guide pipe C is connected with the one-way valve B, the inflation device inflates the ulnar artery side air bag through the one-way valve B and the air guide pipe C, and the radial artery is pressed at the same time.

[0011] Further, the bandage A and the bandage B are independent, the hook-and-loop fastener A and the hook-and-loop fastener C are bonded, and the hook-and-loop fastener B and the hook-and-loop fastener D are bonded, so that the wrist thickness of each patient and the radial artery and ulnar artery compression position can be adjusted.

[0012] Further, the bandage B is provided with a support plate with an arc, which is used to prevent the bandage A and the bandage B from being bonded to excessively press the whole wrist and affect blood circulation.

[0013] The radial artery and the ulnar artery are widely anastomosed together through the superficial palmar arch and the deep palmar arch of the palm part, and the palm part is supplied with blood together, the blood flow of the radial artery can be increased when the ipsilateral ulnar artery is pressed, so that the release of vasodilator medium (blood flow-mediated vasodilation) is increased, and the incidence of radial artery occlusion is reduced.

[0022] The inflation device inflates the radial artery side large air bag 1 and the radial artery side small air bag 2 through the one-way valve A6, the total air guide pipe 5, the air guide pipe A3 and the air guide pipe B4, and the directional extrusion of the radial artery side large air bag 1 and the radial artery side small air bag 2 can point compression and realize more accurate compression hemostasis of the radial artery, and the point compression force point can be reflected in the radial artery side mark point 7, which can help positioning when the arterial catheter is removed.

[0023] The ulnar artery side air bag 8 is connected with the air guide pipe C9, the air guide pipe C9 is connected with the one-way valve B10, the inflation device inflates the ulnar artery side air bag 8 through the one-way valve B10 and the air guide pipe C9, and the force point of the ulnar artery side air bag 8 on the ulnar artery compression is reflected in the mark point B11, which can help positioning when selecting the compression point. It is realized that the radial artery is compressed at the same time, and the ipsilateral ulnar artery is compressed; or after stopping the compression of the radial artery, the ulnar artery is continuously compressed without changing, removing or increasing any compression equipment.

[0024] The band A12 and the band B15 are independently separated, the radial artery compression point is positioned by the radial artery side mark point 7, and the ulnar artery compression point is positioned by the ulnar artery side mark point 11, then the touch fastener strip A13 and the touch fastener strip C16 are adhered, and the touch fastener strip B14 and the touch fastener strip D17 are adhered, so that the two bands are adhered together and fixed through the touch fastener strips, so that the two bands can be adjusted according to the thickness of the wrist of each patient, the compression positions of the radial artery and the ulnar artery.

[0027] Method two: after the radial artery puncture point is completely hemostatic, release the gas in the radial artery side balloon, inject more gas into the ulnar artery measuring balloon, use the blood oxygen saturation meter to measure the blood oxygen saturation, if the blood oxygen saturation decreases to below 95% or cannot be measured, slowly release the gas in the ulnar artery side balloon until the blood oxygen saturation reaches above 95%, at this time, the ulnar artery side balloon still has gas, which can compress the ulnar artery, through increasing the blood supply of the radial artery, the occluded radial artery is unobstructed in a short time, at the same time, it does not affect the blood supply of the hand.

[0028] Method one and method two can be used in combination to achieve the two purposes of preventing and treating radial artery occlusion.
