Abstract
An infusion speed control switch belongs to the technical field of medical instruments and consists of a sleeve, a threaded pipe, a bolt, a limit plate, a supporting rod, a squeezing plate and a supporting spring. The infusion speed control switch is characterized in that the lateral wall of the sleeve with a square section is connected with the threaded pipe with a thread on the inner wall; the lateral wall of the sleeve is provided with a through hole communicated with the threaded pipe, the inside thread of the upper end of the threaded pipe is connected with the bolt, and the lower end of the bolt is supported on the upper surface of the limit plate; the upper end of the supporting rod is connected with the limit plate, the lower end of the supporting rod passes through the through hole and is connected with the squeezing plate in the sleeve, and the part of the supporting rod between limit plate and the outer wall of the sleeve is provided with the supporting spring. The utility model has the advantages of simple structure, convenient use and accurate infusion speed control, the infusion speed can not be automatically changed, and convenience is brought to the work of medical personnel.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of transfusion speed gauge tap.
Background technology
At present, the one-time infusion tube that medical institutions use all carries transfuse switch, the structure that the transfuse switch that carries all adopts skewed slot to add roller bearing is controlled transfusion speed, this transfuse switch not only is difficult to the transfusion speed precise control, and roller bearing landing automatically sometimes, cause very burden to medical personnel.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of transfusion speed precise control is provided, and can not change the transfusion speed gauge tap of transfusion speed voluntarily.
The purpose of this utility model is achieved in that this transfusion speed gauge tap is made up of sleeve pipe, corrugated tubing, bolt, limiting plate, support bar, stripper plate, support spring, the cross section is to be connected with the corrugated tubing that inwall is provided with screw thread on the quadrate sleeve pipe sidewall, have the through hole that communicates with corrugated tubing on the sleeve pipe sidewall, corrugated tubing upper end internal whorl is connecting bolt, and the bolt lower end withstands on the limiting plate upper surface; Post upper links to each other with limiting plate, and the lower end is passed through hole and linked to each other with stripper plate in the sleeve pipe, is with support spring on the support bar between limiting plate and the sleeve outer wall.
During transfusion, the clockwise direction rotating bolt, bolt pushes the tube for transfusion in the sleeve pipe by limiting plate, support bar, stripper plate; Counterclockwise rotating bolt under the effect of support spring, moves on the stripper plate, alleviates the extruding to tube for transfusion, makes transfusion speed reach required state.
Advantage of the present utility model: simple in structure, easy to use, the phenomenon of transfusion speed can not take place to change voluntarily in the transfusion speed precise control, brings convenience for medical personnel's work.
Description of drawings
Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this transfusion speed gauge tap is made up of sleeve pipe 1, corrugated tubing 2, bolt 3, limiting plate 4, support bar 5, stripper plate 6, support spring 7, the cross section is to be connected with the corrugated tubing 2 that inwall is provided with screw thread on quadrate sleeve pipe 1 sidewall, have the through hole that communicates with corrugated tubing 2 on sleeve pipe 1 sidewall, corrugated tubing 2 upper end internal whorls are connecting bolt 3, and bolt 3 lower ends withstand on limiting plate 4 upper surfaces; Support bar 5 upper ends link to each other with limiting plate 4, and the stripper plate 6 that the lower end is passed in through hole and the sleeve pipe 1 links to each other, and is with support spring 7 on the support bar 5 between limiting plate 4 and sleeve pipe 1 outer wall.
