Abstract
A blood returning prevention infusion tube consists of an upper infusion tube which is connected with the upper part of a drip cup, and a lower infusion tube which is connected with the lower part of the drip cup. The utility model is characterized in that a floating object with magnetic property is arranged in the drip cup; a magnetic lantern ring is arranged on the infusion tube. When the infusion begins, the magnetic lantern ring is moved to close sleeved at the bottom of the drip cup. When the infusion is finished and the drip cup has no liquid medicine, the floating object with magnetic property moves downward and closes the liquid medicine outlet under the action of magnetic force, thereby achieving the purpose of preventing from blood returning and secluding air. The utility model has the advantages of simple operation, effectively reducing the dispute between doctors and patients caused by blood returning in the process of infusion, and having good social benefit.
Description
Technical field
This utility model belongs to medical instruments.
Background technology
The tube for transfusion that uses must someone be looked after in infusion process at present, when will using up, the tube for transfusion inner liquid medicine must notify medical personnel in time to pull out pin immediately, otherwise the venous blood into situation of tube for transfusion that flows backwards will appear, normal claim " blood back ", the phenomenon of air admission blood vessel also can take place sometimes, impacts to patient health.
Summary of the invention
The purpose of this utility model is to provide a kind of tube for transfusion that can prevent blood back, can prevent the venous blood into tube for transfusion that flows backwards in the time of will using up in transfusion, the purpose of this utility model realizes by technical scheme shown in the drawings, tube for transfusion is formed by dripping kettle, be connected the upper tubing that drips the kettle top and be connected the following tube for transfusion that drips the kettle below, of the present utility modelly be characterised in that being provided with one in dripping kettle has the cursory of magnetic, is provided with a magnetic collar on the infra tube for transfusion.During the transfusion beginning, cursory the floating over of magnetic force dripped on the kettle giving drugs into nose liquid level, the mobile magnetic collar is locked it and is dripping the kettle bottom, when will using up, transfusion drips no medicinal liquid in the kettle, this moment, magnetic was cursory to move down, with the active force of magnetic collar magnetic force under will drip the sealing of kettle liquid outlet, thereby reach the purpose that prevents blood back, secluding air.This utility model does not change the tube for transfusion original structure, and simple to operate, can reduce the dispute that takes place because of the transfusion blood back between the doctors and patients effectively, has the good social benefit.
Description of drawings
Accompanying drawing 1 is this utility model structural representation Fig. 1, the cursory floating state that is among the figure;
Accompanying drawing 2 is this utility model structural representation Fig. 2, and the cursory sinking state that is among the figure will drip the sealing of shell liquid outlet.
Legend: 1, magnetic is cursory; 2, drip kettle; 3, the magnetic collar.
The specific embodiment
Magnetic is cursory to be made by magnetic rubber with the collar, and cursory upper end is hemispherical, and the lower end has one can insert the obstruction of dripping the kettle liquid outlet.The magnetic collar becomes horn-like, and its upper port matches with dripping the outside lower end of kettle shape, and its bottom diameter can closely cooperate it with following tube for transfusion outer wall, and it can tightly be enclosed within on the tube for transfusion, tube for transfusion can not flattened again.
Claims (1)
1. the blood return prevention tube for transfusion is formed by dripping kettle, be connected the upper tubing that drips the kettle top and be connected the following tube for transfusion that drips the kettle below, it is characterized in that being provided with one in dripping kettle has the cursory of magnetic, is provided with a magnetic collar on the infra tube for transfusion.
