AI Technical Summary

Technical Problem

Traditional central venous catheters may have adherence in the blood vessels, resulting in poor blood flow, affecting the effect of hemodialysis, and may cause complications such as thrombosis.

Method used

A central venous catheter for hemodialysis with an adhesive-proof assembly is designed. The end of the catheter is equipped with an adhesive-proof assembly, including a retractable wire mesh cover, which controls the expansion or contraction of the wire through a driving mechanism to prevent the catheter from being attached to the wall and prevent thrombosis from entering.

Benefits of technology

Effectively prevent central venous catheter from adhering to the wall, ensure stable blood flow, reduce the risk of thrombosis, and improve the safety and effectiveness of hemodialysis.

Abstract

The invention discloses a hemodialysis central venous catheter with an anti-adherence assembly, and relates to the technical field of hemodialysis, the hemodialysis central venous catheter comprises a double-cavity central venous catheter body, the outer end of the double-cavity central venous catheter body is connected with a connector, the upper end of the connector is connected with a blood outlet pipe and a blood inlet pipe, and the blood outlet pipe and the blood inlet pipe are connected with an anti-adherence assembly. The blood outlet pipe is connected with the blood inlet end of the hemodialysis instrument, and the blood inlet pipe is connected with the blood outlet end of the hemodialysis instrument. The blood outlet and the blood inlet of the central venous catheter are formed in the front end of the central venous catheter, the situation that the side edge of the blood outlet is prone to being attached to the wall to affect the bleeding amount is avoided, meanwhile, the wall attachment preventing assembly is arranged at the end of the central venous catheter, and a gap is formed between the end of the central venous catheter and the blood vessel wall; and the phenomenon that the central venous catheter adheres to the wall is further prevented, so that bleeding and blood inflow of the central venous catheter are guaranteed, and the dialysis effect of a patient is improved.
