AI Technical Summary

Technical Problem

The existing thrombolytic catheter fixation method for treating thrombosis through internal jugular vein has problems such as insufficient adhesion, easy dislocation of the catheter, bleeding, inconvenience to patients with excessive length of the catheter segment, and the risk of infection caused by residual tape.

Method used

The fixed connection part including thrombolysis catheter, one-way clamping sleeve, one-way clamping joint, conveying pipe, one-way valve joint and rubber sealing ring is adopted to achieve a firm fixation of the catheter through the one-way clamping sleeve and spring. After the catheter is cut, the catheter is fixed with a spiral climbing delivery tube and an airbag valve to avoid tape sticking, and ensure effective thrombolytic exudation through the Luer screw joint and one-way valve.

Benefits of technology

It effectively avoids the inconvenience of the excess catheter to the patient, ensures fixation and stability, reduces the risk of infection, improves the thrombolysis effect, and simplifies the operation process.

Abstract

The present invention relates to the field of medical devices, and specifically to a thrombolytic catheter device for treating thrombus through the internal jugular vein, comprising a thrombolytic catheter and a fixed connection part of the thrombolytic catheter; the fixed connection part of the thrombolytic catheter comprises: a fixed catheter, a one-way clamping sleeve, a one-way clamping joint, a delivery tube, and a one-way valve joint. When in use, the thrombolytic catheter is inserted into the patient's neck blood vessel into the body and delivered to the thrombus, the excess part of the thrombolytic catheter retained outside the body is cut off and discarded, and the thrombolytic catheter is inserted into the one-way clamping joint, at which time the one-way clamping sleeve clamps the outer wall of the thrombolytic catheter. At this time, the spiral climbing of the delivery tube at the rear end of the fixed catheter will not fall on the patient's skin. Then, the external thrombolytic agent injection tube is screwed and connected at the one-way valve joint at the upper end of the spiral climbing of the delivery tube. The thrombolytic agent is injected from the thrombolytic agent injection tube into the one-way valve joint, and the thrombolytic agent seeps out from the thrombolytic hole to thrombolyze the external thrombus. After that, the thrombolytic agent injection tube can be removed, which is simple, convenient and practical.
