CN223696555U - Anti-drop venipuncture tube - Google Patents

Abstract

This utility model discloses an anti-dislodgement intravenous puncture catheter, including a tube body and a suction cup base. Multiple suction cups are evenly distributed on the bottom of the suction cup base, and a puncture operation port is opened at the center of the suction cup base corresponding to the puncture point. The biomimetic structure of the suction cups adsorbs and fixes the catheter to the patient's skin, ensuring a good fixation effect while effectively avoiding skin discomfort caused by dressing adhesive. The elastic telescopic connecting strap and tube body fixing seat reduce the pulling at the puncture point of the tube body and prevent the puncture end of the intravenous puncture catheter from slipping. Except for the tube body, the entire device can be repeatedly cleaned, disinfected and reused. Through the combination of biomechanical optimization and external force buffering structure, the risk of emergency catheter dislodgement is systematically reduced without significantly increasing medical costs, making it particularly suitable for the chaotic and busy work scenarios of emergency departments.
