Abstract

The present invention relates to the field of medical device technology. Specifically, it provides a puncture locking connector and an adhesive-free, chemical-solvent-free fluid set. The puncture locking connector comprises the following members, which are integrally molded from top to bottom and installed sequentially: a conical puncture head having an inclined puncture hole; a position limiting plate having a puncture end and a gripping end installed facing each other, wherein the conical puncture head is positioned vertically on the puncture end and the position limiting plate is configured to limit the displacement of the conical puncture head; a gripping part having a rectangular body, wherein one end of the rectangular body is installed vertically with respect to the position limiting plate; and a connecting tube having one end fixedly installed on the other end of the rectangular body, wherein a liquid discharge hole is installed on the other end, and the liquid discharge hole is connected to the inclined puncture hole. Furthermore, compared to a conventional cylindrical gripping structure, the frictional force during gripping is increased to prevent slipping problems caused by sweaty hands or improper hand posture of medical personnel, thereby ensuring greater stability and safety during the operation process.

Description

PUNCTURE LOCK CATCH CONNECTOR AND GLUE-FREE AND CHEMICAL-SOLVENT-FREE INFUSION ASSEMBLY The present invention relates to the field of medical device technology, and in particular to a puncture locking connector and an adhesive-free, chemical-solvent-free fluid set. Currently, the main body of the trocar of the IV tubing set is generally equipped with a puncture head and a gripping part. However, the grip of most existing trocars is installed with a cylindrical structure, making it unstable and prone to slipping when held by medical personnel. An unstable grip can cause the puncture head to unintentionally puncture the skin, posing a safety risk to medical personnel when using the trocar. Therefore, the prior art has defects and shortcomings, requiring further improvement and development.
