Abstract

The present invention relates to the field of medical devices, and more particularly, to a perfusion liquid drug delivery device for intestinal surgery, comprising a drug delivery tube, a control shaft, a sliding sleeve, a spherical blocking head and a guide frame; A medicine inlet chamber is arranged in the middle, a medicine outlet is arranged at one end of the medicine tube, and a medicine inlet tube is arranged at the other end of the medicine tube, and the medicine outlet, the medicine inlet chamber and the medicine inlet tube are connected in sequence; the control shaft The outer end of the control shaft is sealed and rotatably fitted in the shaft hole of the drug delivery tube, and the shaft hole is set on the same side as the drug feed tube; the inner end of the control shaft is provided with a first thread, and the first thread is connected to the sliding sleeve thread through the first thread Matching connection; spherical blocking head is used inside the present invention to block the drug outlet of the drug delivery tube, and the size of the gap can be changed by adjusting the relative position of the spherical blocking head and the drug outlet of the drug delivery tube, so as to control the filling liquid Dosing rate.

Description

technical field [0001] The present invention relates to the field of medical instruments, and more particularly, to an irrigation liquid drug delivery device for intestinal surgery. Background technique [0002] At present, enema is generally performed before the operation of intestinal surgery, which can fully remove the feces in the intestinal cavity and facilitate the operation. Specifically, the enema is used before the operation. However, the size of the drug delivery port of the existing perfusion liquid drug delivery device is fixed, and the speed of perfusion liquid drug delivery cannot be adjusted and controlled. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an irrigation liquid drug delivery device for enteral surgery, which can effectively solve the problems in the prior art. [0004] In order to achieve the above purpose, the present application provides a perfusion liquid drug delivery device for enteral surgery, compris...
