AI Technical Summary

Technical Problem

Conventional vascular access devices face challenges in efficiently collecting blood without contamination due to fibrin sheath or thrombus blockage and tube bending issues during prolonged use, as described in Japanese Patent Application Laid-Open No. 2019-136548.

Method used

A vascular access device with a flexible tube and a hollow cover that includes a bending suppression portion to prevent tube deflection, allowing the tube to protrude from the catheter tip and maintain a clear aspiration pathway, featuring a telescopic structure with multiple deflection suppression parts and a contraction maintenance mechanism to ensure effective blood collection.

Benefits of technology

The device effectively suppresses tube bending and prevents blockage by foreign objects, ensuring reliable blood collection without contamination by positioning the tube opening away from the catheter tip and maintaining a clear suction path.

Abstract

This vascular access device (10A) comprises: a distal-end-side connector (12); a tube (14) with flexibility that is inserted into the distal-end-side connector (12); a proximal-end-side connector (16) that is fixed to a proximal end of the tube (14); and a hollow cover (18A) that covers the tube (14) between the distal-end-side connector (12) and the proximal-end-side connector (16) and is capable of contracting in the axial direction. The cover (18A) has a deflection suppression part (34) that suppresses deflection of the tube (14). The tube (14) protrudes from a distal end of a catheter (100) as the tube (14) moves in the distal direction relative to the distal-end-side connector (12).
