Extended pipe with continuous positive pressure and liquid stop clip with extended pipe

Abstract

The present invention relates to the technical field of medical devices and particularly discloses an extended pipe with continuous positive pressure and a liquid stop clip with the extended pipe. Theextended pipe comprises a hollow-shaped extended pipe body, a positive pressure body passes between an inner wall and an outer wall of the extended pipe body, when both sides of the outer wall of theextended pipe body are pressed, both sides of the inner wall of the extended pipe body are against the pressure, and the positive pressure body is pressed against one side of the inner wall of the extended pipe body, so that the both sides of the inner wall of the extended pipe body form a gap; and the liquid stop clip comprises a left clamping arm, an upper end of the left clamping arm is bent and extended with a right clamping arm, the left clamping arm is provided with a first elastic body and the right clamping arm is provided with a second elastic body. The extended pipe is simple in structure and has a function of continuous positive pressure and an anti-thrombosis effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an extension tube for continuous positive pressure and a liquid stop clip with the extension tube. Background technique [0002] Infusion set, or infusion pump, as the name suggests, is a medical device for infusion. The traditional infusion method is to hang the liquid contained in the bottle or the infusion bag at a high place, and utilize the effect of gravity to make the liquid flow into the vein through the infusion leather tube. However, after the extension tube on the existing infusion set is connected with the indwelling needle, the hollow extension tube only has the function of guiding the liquid. Generally, a liquid stop clip is installed on the extension tube. The liquid stop clip in the prior art clamps the extension tube. Finally, it plays the role of hemostasis, which is easy to cause thrombus reflux. Contents of the invention [0003] Aiming at the prob...
