Description

Technical Field

[0001] The invention relates to the technical field of blood vessel puncture, in particular to a hemostatic device for blood vessel leakage which is convenient for adjusting local pressure. Background Art

[0002] Coronary angiography is an interventional procedure commonly used to diagnose and treat coronary artery disease. However, damage and leakage at the vascular puncture site may occur after the procedure, which is one of the common complications of interventional surgery. Postoperative vascular damage is mainly manifested as hematoma around the puncture site, vascular leakage, and local swelling of the forearm. If this leakage is not treated promptly and effectively, it may cause severe local compression symptoms and even affect limb blood supply, causing complications such as tissue ischemia and pain.

[0003] However, the traditional treatment method usually uses gauze pressure bandage to stop bleeding, but this method has many disadvantages, such as the difficulty in evenly distributing pressure, excessive pressure may lead to poor blood circulation, and insufficient pressure cannot effectively stop bleeding. In addition, the gauze bandage process requires frequent adjustments, and manual operation is not only cumbersome but also difficult to maintain a stable pressure effect;

[0004] Therefore, based on the above problems, a hemostatic device for vascular leakage that is easy to adjust local pressure is proposed, so as to wrap the patient's entire forearm, and the entire device is pressurized in a multi-stage manner and electrically inflated and deflated, so as to achieve the effect of compression hemostasis according to demand and avoid complications of insufficient blood supply. Summary of the invention

[0005] The present invention is intended to provide a hemostatic device for vascular leakage that is easy to adjust local pressure, so as to solve the problem that the prior art usually uses gauze pressure bandage to stop bleeding, but this method has many disadvantages, such as it is difficult to evenly distribute the pressure, excessive pressure may lead to poor blood circulation, and insufficient pressure cannot effectively stop bleeding. In addition, the gauze bandage process requires frequent adjustments, and the manual operation is not only cumbersome but also difficult to maintain a stable pressure effect.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The technical solution provided by the present invention is: a hemostatic device for vascular leakage that is easy to adjust local pressure, including a device terminal, one side of the device terminal is connected to a cuff structure, a number of pressure airbags are evenly arranged in the cuff structure, a number of adjustment devices that are compatible with the pressure airbags are fixedly arranged on the outside of the cuff structure, and a pulse oximeter is movably provided at one end of the cuff structure.

[0008] Furthermore, a touch screen control panel is provided on the surface of the device terminal, a pressure tube is fixedly provided on one side of the device terminal, and a wire tube is fixedly provided on one side of the device terminal. The touch screen control panel displays various data in real time, including the current pressure value of each pressure airbag, inflation and deflation time, pulse rate, blood oxygen saturation, etc. Medical staff can easily adjust the pressurization intensity and various monitoring parameters according to the data displayed on the interface.

[0009] Furthermore, the cuff structure includes a cuff fixedly installed at one end of the pressure tube, a Velcro mother surface is fixedly provided on the outer wall of one side of the cuff, and a Velcro sub-surface is fixedly provided on the other side of the cuff, the Velcro sub-surface is connected to the Velcro mother surface, and the cuff adopts a long cuff design to cover the leakage area of ​​the entire forearm, and is wrapped and fixed by the Velcro sub-surface and the Velcro mother surface, while being able to be adjusted according to the size of the patient's arm so that it can be more firmly fixed to the patient's arm.

[0010] Furthermore, there are five groups of pressure airbags evenly installed on the inner wall of the sleeve. There are multiple independently inflatable pressure airbags distributed on the sleeve, totaling to 10 pressurization sections. Each pressure airbag can be inflated and deflated individually as needed, such as applying pressure only to the front 1 / 3 of the arm, to flexibly respond to the needs of different leakage sites. Pressure sensors are installed in the pressure airbags to monitor the pressurization and ensure that the pressure remains within the set range to avoid over-pressurization or under-pressurization.

[0011] Furthermore, the adjustment device includes an adjustment plate fixedly mounted on the outside of the sleeve, the adjustment plate is connected to the wire tube, electrically connects the micro air pump and the exhaust valve, increases the aesthetics of the device, and covers the power cord connected thereto.

[0012] Furthermore, a number of micro air pumps and exhaust valves are evenly arranged on one side of the adjustment plate, and an air pipe is fixedly arranged below the micro air pump and the exhaust valve. The air pipe passes through the cuff and is communicated with the pressure air bag. Each segmented pressure air bag is inflated by the micro air pump. The micro air pump can be linked with an independent electronic control module in the equipment terminal through a wire pipe to intelligently control the inflation volume of each pressure air bag to ensure the local pressurization effect. The exhaust valve is deflated regularly or according to the set pressure level to maintain good blood circulation and avoid local blood supply deficiency caused by long-term pressurization.

Nylon has good strength and durability, and is also relatively light. Polyvinyl chloride has good wear resistance and waterproof characteristics to cope with long-term use, ensuring that it is not easy to slide during use, and is comfortable and breathable when worn by patients, reducing skin discomfort. The device is made of soft material and is easy to clean and disinfect, meeting the hygiene requirements of the medical environment.
