Abstract
The utility model relates to a safety transfusion device, and belongs to the medical equipment. A floating plug is arranged in a Murphy's drip pipe. When the liquid finishes transfusing, the liquid level in the drip pipe falls down and automatically seals the transfusion pipeline. The air is effectively prevented from entering the vein. The utility model has the advantages of safety, easy use, low production cost, etc.
Description
Technical field
This utility model is a kind of intravenous drip transfusion device, particularly a kind of when liquid is totally lost the timely safe transfusion system of closing pipe line.Belong to medical apparatus and instruments.
Background technology
The intravenous transfusion device that present hospital generally uses is by syringe needle, and rubber tube and Murphy's burette etc. are formed.Whether its liquid is totally lost is observed by Murphy's burette, does not in time pull out pin in case liquid is totally lost, inner air tube with regard to might the time go into vein and cause thromboembolism, particularly danger is bigger when pressure transfusion, but threat to life when serious.Therefore, medical personnel and guest invited to a dinner party need in time to observe liquid level in the bottle, make troubles to nursery work.
Summary of the invention
The purpose of this utility model be to provide a kind of when liquid is totally lost the timely safe transfusion system of closing pipe line.
The technical solution of the utility model is to consider like this: add a floating plug in the Murphy's burette of transfusion device, in the instillation process, floating plug floats on the Murphy's burette middle part, when the liquid in the saline bottle is totally lost, liquid level in the Murphy's burette will descend, floating plug is automatic closing pipe line thereupon descending, and the liquid in the following pipe of dropper does not reinject in the body, has stoped in the air admission human vein.
When this utility model can guarantee that normal infusion finishes, seal infusion pipeline automatically, stop in the air admission human vein, guarantee the safety of infusing, and with low cost, easy to use, minimizing medical personnel's nursing work load.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
The specific embodiment
In the inside of Murphy's burette 1, be provided with floating plug 2, this floating plug 2 is made up of the latex thin film capsule of band water wing.During use, connect the downcomer 3 and the upper conduit 4 at dropper 1 two ends earlier, liquid enters dropper 1 through upper conduit 4.With the 1 accumbency several seconds of dropper, make liquid enter dropper 1 and remain with the liquid of some, hard then straight dropper.The water wing proportion of floating plug 2 floats on liquid upper less than liquid together with the thin film capsule.At first splash in the capsule of floating plug 2 from the liquid of upper conduit 4, make it to become a hydatid cyst, liquid enters downcomer 3 after overflowing in the capsule, implements intravenous drip.After the liquid infusion in the infusion bottle is intact, upper conduit 4 no longer injects liquid in dropper 1, liquid level in the dropper 1 descends, floating plug 2 descends thereupon, when floating plug 2 was reduced to dropper 1 bottom, the thin film capsule that has liquid was with the closely knit sealing of the outlet of dropper 1, and upper pressure is big more, seal tightly more, guarantee that air does not enter in the body.
Claims (2)
1, a kind of intravenous transfusion device comprises Murphy's burette 1, upper conduit 4, and downcomer 3 and syringe needle etc. is characterized in that being provided with in the described Murphy's burette 1 floating plug 2.
2, transfusion device as claimed in claim 1 is characterized in that described floating plug 2 is the thin film capsule of a band water wing.
