Antibacterial type conduit sheath

Abstract

The invention provides an antibacterial type conduit sheath for interventional therapy, which comprises an antibacterial conduit sheath pipe, a conduit sheath seat and a three-way valve, which are sequentially connected and communicated with each other. The production method the antibacterial conduit sheath comprises the following steps of: mixing antibacterial medicine, metal tungsten powder-prepared antibacterial powder with plastic master grains according to a certain proportion, refining in a mixing way, extruding and shaping, wherein the weight of the antibacterial powder is 1-50% of the gross weight of the antibacterial conduit sheath pipe. The antibacterial type conduit sheath has the advantages of safety, reliability, high antibacterial performance, simple production technology and low cost.

Description

technical field [0001] The invention relates to an catheter sheath for interventional therapy, in particular to an antibacterial catheter sheath for interventional therapy. Background technique [0002] At present, in the treatment of cardiovascular diseases, interventional therapy has been widely used due to its advantages of less bleeding, less trauma, fewer complications, safety and reliability, and quick postoperative recovery. Treatments like this often require frequent and continuous delivery of some interventions or fluids into the patient's body. The catheter sheath is like a relatively fixed pipeline, which is convenient for the catheter to go in and out or to replace the catheter multiple times. [0003] When puncturing, put the catheter sheath on the catheter or dilation tube and enter the blood vessel along the guide wire, pull out the guide wire or dilation tube and leave the catheter sheath in the blood vessel as a channel for the catheter to enter and exit or ...

Problems solved by technology

This does have the effect of sterilizing and inhibiting the growth of bacteria, and achieves a certain antibacterial effect. However, due to many unpredictable factors during the interventional operation, or the operation itself is very difficult, this requires the sheath to stay in the body for a long time. However, after the antibacterial material coating of the ordinary catheter sheath is in contact with the blood for a long time, the antibacterial power begins to drop significantly, and what is more, the coating peels off, which makes the antibacterial persistence of the catheter sheath poor, resulting in its antibacterial The purpose cannot be achieved, and may even affect the realization of the purpose of diagnosis and treatment

At the same time, the production method of applying the antibacterial coating to the inner and outer surfaces of the pipe body by infiltration must be completed through another process after the pipe body is extruded, resulting in low production efficiency and high cost
