Problems solved by technology

But they all exist together: the operation process is too cumbersome, the price is too high, and the closing effect is different.
Moreover, due to the high price of imported closers, most hospitals in China have to choose to use the most basic intraoperative manual compression, followed by pressurized bandaging to restrict activities to deal with vascular punctures

Embodiment

[0030] The production process and steps 1. The "I"-shaped closer model is made, the satellite is differentially centrifuged, and the casting is formed. Polymer materials usually use stirring dissolution and negative pressure suction defoaming technology in the solution dissolving, mixing and dispersing operations. This method is not only inefficient, easy to retain bubbles, but also difficult to guarantee the quality. The invention adopts the satellite differential speed centrifugation method, which has the functions of fast and uniform mixing and simultaneously driving away the air bubbles in the solution, fully dissolves, and has outstanding defoaming and uniform dispersion functions, thereby ensuring the quality of the manufactured shutter.

[0031] 2. Manufacturing of sheath tube and push tube.

[0032] 3. "I"-shaped shutter, sheath tube, and push tube are integrated and installed, sealed and packaged.

[0033] After the punctured short sheath is inserted into the blood v...

Abstract

The invention discloses a blood vessel puncture mouth I-shaped blanker for interventional medicine and a manufacturing method thereof. The blanker is of an I-shaped structure shown in figure (1), andis composed of a blanker body (1), a blanker inner sheath (2), a blanker outer sheath (4), a control disc (3), a control disc (5), an inner core pipe (6), an inner core pipe (7) and a connecting line(8). The I-shaped blanker is made from biodegradable macromolecular polymers, the inner wall and the outer wall of a blood vessel are clamped through an inner buckling disc and an outer buckling discwith high-elasticity memory performance, the blanker can be completely degraded within 4-6 weeks, and regeneration and restoration of the walls of the blood vessel are benefited. The blood vessel puncture mouth I-shaped blanker is easy and convenient to operate, a blood vessel puncture mouth can be effectively closed, postoperative risks can be effectively reduced, and the pain and the strength ofmedical care are relieved.

Description

technical field [0001] The invention relates to an I-shaped vascular puncture port shutter for interventional medicine and a manufacturing method thereof, in particular to a shutter for closing a vascular puncture port after a minimally invasive interventional operation and a manufacturing method thereof, belonging to the field of medical devices. Background technique [0002] In recent years, minimally invasive interventional therapy through blood vessels has been widely used in clinical practice. It is based on the tracer monitoring and observation of medical imaging equipment to deliver interventional medical devices to important organs and parts of the human body, such as: heart, brain, kidney, digestive system, It is a new technology and method for diagnosis and treatment of the reproductive system, which has the advantages of less trauma, significantly shortened treatment process and hospitalization time, and relatively low medical expenses. The use of minimally invasi...
