Description
Technical Field
[0001] The utility model relates to the technical field of hemostatic patches, in particular to a pressurized hemostatic patch used after a puncture tube is removed. Background Art
[0002] The radial artery is one of the most important arteries in the upper limbs of the human body. The blood in the radial artery is rich in oxygen and nutrients, which can penetrate into the surrounding tissues through the blood vessel wall to meet the metabolic needs of the human body. Radial artery puncture and catheterization refers to the insertion of a cannula into the radial artery, which is connected to an external device to monitor the patient's blood pressure in real time. Arterial puncture and catheterization can also be used to indwell an arterial sheath and place a guidewire catheter into the arterial cavity to achieve the purpose of treating arterial diseases.
[0003] When the treatment is finished, the cannula is pulled out from the inside of the radial artery, and the puncture site at the radial artery needs to be compressed to stop bleeding. Since the diameter of the cannula used for radial artery puncture and catheterization is relatively thick, the puncture site for the cannula to enter is also relatively large, and the radial artery is an artery with a large blood flow, and it takes a long time and a more appropriate compression force to compress and stop bleeding at the puncture site at the radial artery. The current method of compressing and stopping bleeding at the puncture site at the radial artery is to wrap multiple circles of gauze around the puncture site for compression and stop bleeding. However, the problem of using gauze to wrap for compression and stop bleeding is that the gauze wrapped for multiple circles has a greater restraint on the entire arm, and wrapping too tightly will affect the blood circulation at the arm position, and wrapping loosely will not have enough compression force on the radial artery puncture site, so the effect of using gauze to wrap for compression and stop bleeding at the puncture site at the radial artery is not good.
[0004] Therefore, how to design a pressurized hemostatic patch for use after the puncture tube is removed that can compress the radial artery puncture site with appropriate compression force without causing significant restraint on the entire arm and thus not affecting the blood circulation in the arm is a technical problem that has not yet been solved in the prior art. Utility Model Content
