Problems solved by technology

However, the preparation method of the flexible reinforced epidural anesthesia catheter in the prior art is complicated, the implementation difficulty coefficient is high, the qualified rate of finished products is low, and the precision is not high. Safety hazards such as shrinkage of the external catheter due to weak fusion and inability to spray medicine due to tube detachment
In addition, the flexible and reinforced epidural anesthesia catheter in the prior art has inconvenient cleaning of the internal support spring steel wire, and it is easy to accumulate dust pollution and directly contact with the liquid medicine. Sequelae; In addition, the surface of the spring steel wire is rough, which is not conducive to the circulation of the liquid medicine, the flow rate is reduced, the liquid medicine enters the gap between the spring steel wire, and the residual amount is not easy to control

Abstract

The invention discloses a flexible reinforced epidural anesthesia catheter which is characterized in that the catheter comprises a catheter body, a medicine inlet and a medicine outlet are formed in two ends of the catheter body and connected through a catheter cavity in a penetrating manner, the catheter body includes an outer catheter body and an inner catheter body, the outer catheter body is made of plastic materials with a super-smooth anti-infection function, the inner catheter body is made of steel wire materials, the outer wall of the inner catheter body is uniformly fitted with the inner wall of the outer catheter body through adhesives, a flexible soft head is arranged at one end of the catheter body, and the flexible soft head and the outer catheter body are integrally formed. The flexible reinforced epidural anesthesia catheter is better in comprehensive performance, damage-proof effect is better, the catheter cannot be easily detached and contracted or 'folded', anestheticsolution can be clinically and smoothly infused, the surface of the catheter is super smooth, catheter placing and pushing block of a doctor can be effectively reduced, and secondary injury to vascular tissues can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing, in particular to a flexible and reinforced epidural anesthesia catheter. Background technique [0002] The epidural nerve block in the prior art is an anesthesia method widely used in clinic, and has the advantages of simple operation, low cost, easy management during operation, and convenient epidural analgesia after operation. When using this method of anesthesia, a catheter must be inserted into the epidural space. This catheter is the anesthesia catheter. The performance of anesthesia catheter directly affects the effect of anesthesia, therefore, it is particularly important to develop an anesthesia catheter with excellent performance. [0003] The traditional anesthesia catheter is made of a transparent catheter and a catheter connector. Since the catheter is made of plastic, it is easy to be crushed or folded into a dead angle during operation, resulting in the passage...
