Abstract

The utility model discloses disposable infusion apparatus controlled by a needle-shaped floater valve. The disposable infusion apparatus controlled by the needle-shaped floater valve comprises an infusion tube body. The disposable infusion apparatus controlled by the needle-shaped floater valve is characterized in that a floater with a needle-shaped valve is arranged in the infusion tube body. The disposable infusion apparatus controlled by the needle-shaped floater valve has the advantages that safety of a patient is guaranteed during transfusion, labor intensity and working pressure of nurses are relieved, the structure is simple, cost is low, and installation is convenient.

Description

The valve-regulated disposable transfusion device of a kind of needle-like float
Technical field
This utility model relates to medical supplies, specifically the valve-regulated disposable transfusion device of a kind of needle-like float.
Background technology
When using at present the disposable transfusion device transfusion, when medicinal liquid flows to end in the Murphy's burette in the middle of the tube for transfusion, if untimely changing dressings, near syringe needle and needle tubing, can produce the blood back phenomenon, serious even can cause the air intravasation, cause air embolism, threat to life.
The utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, and provides a kind of needle-like float valve-regulated disposable transfusion device, and the transfusion device of this structure can guarantee the safety of patient when transfusion, alleviates nurse and nursing staff's labor intensity and operating pressure.
The technical scheme that realizes this utility model purpose is:
The valve-regulated disposable transfusion device of a kind of needle-like float comprises the tube for transfusion body, unlike the prior art be: in the tube for transfusion body, be provided with one with the float of needle valve.
Described float is connected to form for the valve line sealing surface that matches with the Murphy's burette outlet and guide post three parts of bottom by the hollow float on top, middle part.
Operation principle of the present utility model is: use Archimedes' principle: the object that is immersed in the liquid is subject to buoyancy upwards, and the size of buoyancy equals to be arranged by this object the gravity of liquid and realizes the control of medicinal liquid position.When the medicinal liquid in the Murphy's burette during to certain position, float descends along with the decline of liquid level, and when the liquid outlet below the clogging Murphy's burette of needle valve below the float, medicinal liquid stops drippage, has guaranteed the safety of patient when transfusion.
Under the normal infusion state, medicinal liquid flows in the Murphy's burette of disposable transfusion device in medicine bottle or medicated bag, when liquid level is enough to make buoys float, needle valve below the float is the liquid outlet that leaves the Murphy's burette bottom, namely is in the normal infusion state.Liquid in medicine bottle or medicated bag flows to end, and when the medicinal liquid height of Murphy's burette the inside began to descend, float descended along with the decline of medicinal liquid face height, and when float dropped to needle valve liquid outlet is blocked, transfusion stopped, and enters the safeguard protection state.
The utility model has the advantages that: not only guarantee the safety of patient when transfusion, alleviated nurse and nursing staff's labor intensity and operating pressure, and also simple in structure, cost is low, and is easy for installation.
Description of drawings
Fig. 1 is the structural representation of this utility model transfusion device under the normal infusion state;
Fig. 2 is the structural representation of this utility model transfusion device under the safeguard protection state.
Among the figure: 1 Murphy's burette, 2 needle valves, 3 float 3-1 ball float 3-2 valve line sealing surface 3-3 guide posts
The specific embodiment
With reference to Fig. 1, the valve-regulated disposable transfusion device of a kind of needle-like float, by Murphy's burette 1 be arranged on that the float 3 with needle valve 2 forms in the Murphy's burette 1, float 3 is by the hollow float 3-1 on top, the valve line sealing surface 3-2 at middle part and guide post 3-3 three parts of bottom connect to form, the ball float 3-1 on top is the device that produces buoyancy, the valve line sealing surface 3-2 at middle part and Murphy's burette 1 outlet match, when descending, 1 li liquid level of Murphy's burette impel float 3 and needle valve 2 to descend along with the decline of liquid level, finally making valve line sealing surface 3-2 arrive the bottom closes liquid outlet, the guide post 3-3 of bottom has played ballast and Stabilization, and the used material of whole needle valve float is identical with the material that transfusion device uses.
Quality, center of gravity, buoyancy and the shape of this utility model needle valve float can design and adjust according to the shape size of Mo Feier dropper and the proportion of the liquid of carrying.
