Vascular puncture sealing device

Abstract

A vascular puncture sealing device can seal vascular to arrest bleeding and reduce operation steps. The vascular puncture sealing device includes a tube unit and a sealing unit, wherein the tube unitincludes an inner tube and an outer tube, the inner tube includes a first compartment therein, the outer tube includes a second compartment therein, the inner tube is slidably received in the second compartment, the sealing unit is coupled to an end of the inner tube and includes an abutting portion and an expansion portion, the abutting portion includes a first face and a second face opposite tothe first face; the abutting portion further includes a through-hole extending from the first face through the second face, and the expansion portion includes a chamber intercommunicated with the through-hole of the abutting portion.

Description

technical field [0001] The invention relates to a medical device, in particular to a blood vessel puncture sealer which can seal blood vessels to stop bleeding and reduce operation steps after blood vessel puncture. Background technique [0002] Vascular interventional technology, especially the interventional diagnosis and treatment of cardiac catheterization, refers to percutaneous puncture of blood vessels and placement of sheaths. Through the placed sheath, blood vessels or other lumens in the body can be entered from outside the body, and the medical behavior is performed along the blood vessels towards the medical target. Compared with surgical treatment, it has the advantages of smaller wound and shorter recovery time. [0003] After the vascular interventional technique is performed, the indwelling sheath must be removed. At this time, the puncture hole of the vessel wall must be sealed to stop bleeding, so as to prevent bleeding at the puncture wound and cause seri...

Problems solved by technology

[0007] In this way, through the first sealing member 92 and the second sealing member 93 abutting against the inner side and the outer side of the blood vessel wall W respectively, an appropriate pressure can be applied to the opening O, and the effect of hemostasis can be achieved; however, In actual operation, it is not easy to locate the second sealing member 93 at a predetermined position on the outside of the blood vessel wall W, so that the hemostatic effect of the existing blood vessel puncture sealer 9 is still poor; The positioning of the first sealing member 92 and the second sealing member 93 is cumbersome to use and causes the doctor to prolong the operation time. Therefore, the existing blood vessel puncture sealing device 9 still needs to be improved.
