Abstract

The utility model relates to a medical instrument, in particular to a safety infusion set, which comprises a Murphy dropper, wherein a floating ball is arranged in the Murphy dropper, and the floating ball is closely fit with the inner wall of the a Murphy dropper lower opening, thereby being capable of automatically stopping transfusing when transfusion finishes, and saving manpower resource and guaranteeing safety of patients at the same time.

Description

A kind of safe transfusion system
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates to a kind of safe transfusion system more specifically.
Background technology
Transfusion device commonly used comprises intubate, Mo Feishi dropper, filter and actuator; Intubate, Mo Feishi dropper, filter are connected with conduit with actuator successively, when infusing to the end, when not had the liquid drip in the Mo Feishi dropper; Should in time take off transfusion device or close actuator and stop transfusion; Otherwise can cause that air admission human body or venous blood are counter to flow, cause serious consequence, particularly the child or lie in a comatose condition, unconsciousness is waken up etc., and the patient more needs other people accompanying and attending to; Yet present transfusion device can only stop transfusion through in time taking off transfusion device or closing actuator; Not only caused waste of manpower resource, and brought certain risk, therefore need a kind ofly can when transfusion is accomplished, can stop the safe transfusion system of infusing automatically to the patient.
Summary of the invention
The purpose of this utility model is to provide a kind of safe transfusion system of infusing of can when transfusion is accomplished, can stopping automatically, and this safe transfusion system can prevent the air admission human body or venous blood is counter flows, and saves the human resources.
To achieve these goals, the technical scheme of this utility model employing is:
A kind of safe transfusion system comprises the Mo Feishi dropper, has a ball float in the described Mo Feishi dropper, and the inwall of described ball float and described Mo Feishi dropper lower openings fits, and described ball float top is hemispherical, and the bottom is cone shape.
Above-described a kind of safe transfusion system, the hemispheric radius of a ball is identical with the conical bottom radius surface and greater than the radius of Mo Feishi dropper lower openings, ball float density is between the density of empty G&W.
Above-described ball float top hemispherical density is less than the density of lower cone shape.
Through adopting the lower cone bodily form and the hemispheric structure in top; Help ball float and get into Mo Feishi dropper lower openings; And better and Mo Feishi dropper lower openings inwall fit tightly; Thereby can when transfusion finishes, stop transfusion automatically, guarantee patient's safety when having saved the human resources.
Description of drawings
Fig. 1 is in the view in the transfusion for the safe transfusion system of this utility model;
Fig. 2 is that the safe transfusion system of this utility model is in the view of infusing when finishing;
Among the figure: 1-Mo Feishi dropper, 2-ball float, 21-ball float top, 22-ball float bottom, 3-Mo Feishi dropper lower openings.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 and specific embodiment this utility model is done explanation further,, but do not limit this utility model with this so that those skilled in the art understand this utility model.
The safe transfusion system of this utility model; Comprise Mo Feishi dropper 1; It is characterized in that; Have a ball float 2 in the described Mo Feishi dropper 1, ball float 2 density between the density of empty G&W, ball float 2 form by top 21 hemisphericals and bottom 22 cone shapes and ball float 2 tops 21 hemispherical density less than the density of bottom 22 cone shapes; The hemispherical radius is identical with the conical bottom radius surface and greater than the radius of Mo Feishi dropper lower openings 3, ball float 2 can fit tightly with described Mo Feishi dropper lower openings 3 inwalls.
When transfusion, ball float 2 floats on the liquid level of Mo Feishi dropper 1 inside, can not have influence on normal transfusion; When waiting to infuse near end, ball float 2 can descend along with Mo Feishi dropper 1 inner liquid level gradually, when Mo Feishi dropper 1 inner liquid flows to end; Ball float 2 can be because gravity embeds the lower openings 3 of Mo Feishi dropper automatically; And because ball float 2 bottoms 22 are bigger than top 21 density, therefore can guarantee that ball float 2 bottoms 22 at first get into Mo Feishi dropper lower openings 3, guarantee that ball float 2 and Mo Feishi dropper lower openings 3 inwalls fit tightly; Thereby blocked flowing of liquid, preventing that air admission human body and venous blood are counter flows.

Claims (3)

1. a safe transfusion system comprises the Mo Feishi dropper, it is characterized in that; A ball float is arranged in the described Mo Feishi dropper; The inwall of described ball float and described Mo Feishi dropper lower openings fits, and described ball float top is hemispherical, and the bottom is cone shape; The hemispheric radius of a ball of said ball float is identical with cone bottom surface radius, and this radius is greater than the radius of Mo Feishi dropper lower openings.
2. a kind of safe transfusion system according to claim 1 is characterized in that, said ball float density is between the density of empty G&W.
3. a kind of safe transfusion system according to claim 1 and 2 is characterized in that, described ball float top hemispherical density is less than the density of lower cone shape.
