Artery puncture needle with self-sealing puncture needle opening

Abstract

The invention discloses an artery puncture needle with a self-sealing puncture needle opening. The artery puncture needle is composed of a puncture needle body 1 and a needle opening self-sealing sleeve 2. The puncture needle enters the artery through the skin, after operation is finished, a part of the needle core is withdrawn until the hemostatic gel is changed into a round shape from a ring shape, then the whole needle is pulled out, the gel is released at the same time when the whole needle is pulled out, the hemostatic gel is pulled out of the needle opening along one path to be automatically plugged, and the bleeding situation can be well reduced through one path of automatic plugging; and local hematoma after arterial puncture can be well avoided, so that the probability of formation of pseudoaneurysm is reduced, postoperative arterial compression and pressure bandaging time is shortened, the comfort and satisfaction degree of a patient are improved, vascular wall healing can be well promoted, bleeding can be reduced, vascular wall healing can be promoted, and bleeding and hematoma can be reduced.

Description

Technical field: [0001] The invention relates to a self-sealing puncture needle port arterial puncture needle. Background technique: [0002] Arterial puncture needle is a puncture device used in arterial puncture interventional surgery and arterial pressure measurement; when performing interventional surgery and arterial pressure measurement, it is necessary to use a puncture needle to establish a channel between the skin and the artery. The existing puncture needles include The outermost cannula and needle core, when the operation is completed, the arterial puncture cannula needs to be taken out. After taking out the puncture sleeve, due to the damage to the blood vessel wall, the needle port left after the puncture is likely to cause bleeding, hematoma or even aneurysm and other complications. Invention content: [0003] In order to overcome the above difficulties, the present invention provides a self-sealing puncture needle port arterial puncture needle. [0004] Th...
