Abstract

The invention provides a double-layer combined anesthesia catheter. The double-layer combined anesthesia catheter comprises a catheter and a catheter connector, wherein the catheter is connected with the catheter connector in an inserting manner; the catheter comprises an inner layer and an outer layer; the inner layer is made of a nylon material and the outer layer is made of a polyurethane material; the inner layer and the outer layer are connected by thermal-melting compounding; a medicine outlet hole is formed in one end, far away from the catheter connector, of the catheter; and a spiral supporting wire is arranged between the inner layer and the outer layer. The inner layer of the catheter, which is made of the nylon material, has high rigidity and good axial stability is provided for the combined catheter; the combined catheter is not easy to bend, fold and flatten; and the nylon material has chemical inertness and is not easily subjected to a chemical reaction with medicine liquid passing through the catheter. The outer layer of the catheter, which is made of the polyurethane material, has high hydrophily and becomes smooth when meeting water, and easily passes through human tissues and skins, so that the friction damages are reduced; polyurethane has good flexibility and good biocompatibility, so that discomfort caused by the fact that the catheter is placed into a spinal dural outer cavity of a patient is alleviated; and the polyurethane is convenient for printing and scale lines can be deeply marked into the outer layer of the catheter.

Description

technical field [0001] The invention belongs to the technical field of medical anesthesia apparatus, and in particular relates to a double-layer composite anesthesia catheter. Background technique [0002] Epidural nerve block is a widely used anesthesia method in clinical practice. It has the advantages of simple operation, low cost, easy management during operation, and convenient epidural analgesia after operation. Since the anesthesia catheter needs to be inserted into the epidural space of the human body by surgical means and remain in the human body for a period of time, the anesthesia catheter needs hard materials to provide good axial stability so that it can be placed without bending and discounting. The soft material of the catheter provides excellent comfort. Traditional single-material catheters are difficult to meet this contradictory special requirement. Most of the market adopts a compromise method and chooses moderately soft and hard nylon elastomers to produ...
