Abstract
An automatic infusion set is characterized in that a ball-falling groove is formed wholly at the bottom of a watching chamber when in working place, a ball-storing chamber is formed wholly at the upper portion of the watching chamber, a closing float ball is arranged in the watching chamber freely and a ball-lifting bag forming a whole body with an infusion tube is arranged between the bottom of the watching chamber and the infusion tube. The closing float ball floats on the medicine liquid when in transfusion, and the closing float ball goes down with the medicine liquid to the bottom of the watching chamber and engages with the ball-falling groove to sealing the watching chamber when the medicine liquid in the watching chamber falls off to the bottom of the watching chamber.
Description
This utility model and a kind of medical instruments relate to transfusion device particularly.
Transfusion device is a kind of medical instruments commonly used in the treatment lysis.But the transfusion device that adopts is being observed constantly to needing the people in the patient infusion process now, causes serious situation such as blood back or air admission blood to prevent medicinal liquid from exposing.This is not to medical personnel and entourage, particularly those have entourage's patient to cause many inconvenience, and especially the situation at night is more apparent outstanding.
In order to address this problem, so the purpose of this utility model is to release a kind ofly to walk the transfusion device that the light time can close automatically when medicinal liquid.
According to this utility model, this purpose is to solve like this: promptly designed a kind of transfusion device, it comprises the minim pipette that connects successively, liquid observing chamber and tube for transfusion, it is characterized in that: on the operating position, be formed with a ball sinking groove on the bottom integrated ground of liquid observing chamber, integrally be formed with a ball storage chamber, in liquid observing chamber, freely be placed with one and close ball float and between the bottom of liquid observing chamber and tube for transfusion, be provided with one and form the bag that rises of integral body with tube for transfusion on the top of liquid observing chamber; Wherein when normal infusion, close ball float and floated on the medicinal liquid face in the liquid observing chamber, when the medicinal liquid in the liquid observing chamber drops to its bottom, close ball float along with dropping to this bottom and form sealing with matching with ball sinking groove.
Advantage according to above-mentioned transfusion device of the present utility model is: when medicinal liquid drops to the liquid observing chamber bottom near being totally lost, close ball float along with the liquid level of medicinal liquid descends until forming sealing with ball sinking groove with matching, promptly automatically closed transfusion device, prevented that thus medicinal liquid from exposing and cause the generation of serious situation such as blood back or air admission blood.
By understanding more this scheme of the present utility model and other favourable configuration and feature the explanation of this utility model preferred embodiment below in conjunction with accompanying drawing.Accompanying drawing is:
Fig. 1: according to the perspective cross-sectional slice of the transfusion device of a preferred embodiment of this utility model.
Fig. 1 represents the transfusion device S according to a preferred embodiment of this utility model, and it comprises the minim pipette 1 that connects successively, liquid observing chamber 2 and tube for transfusion 3, and the structure and the principle of these parts and transfusion device of the prior art are basic identical.Different with transfusion device of the prior art is: from normal operation position, at the bottom integrated of liquid observing chamber 2.Ground is formed with a ball sinking groove 6, integrally be formed with a ball storage chamber 4 on the top of liquid observing chamber 2, in liquid observing chamber 2, freely be placed with one close ball float 5 and between the bottom of liquid observing chamber 2 and tube for transfusion 3, be provided with one with tube for transfusion 3 formation integral body rise bag 7; Wherein when normal infusion, close ball float 5 and floated on the medicinal liquid face in the liquid observing chamber 2, when the medicinal liquid in the liquid observing chamber 2 drops to its bottom, close ball float 5 along with dropping to this bottom and form sealing with matching with ball sinking groove 6.
Working procedure according to this transfusion device of the present utility model is as follows: 1) will close ball float 5 by the position of mobile liquid observing chamber 2 earlier and move in the ball storage chamber 4, in order to avoid it is dirty to block medicinal liquid; 2) after transfusion device and medicinal liquid bottle or bag are connected, under beginning, lets out medicinal liquid, after patient's blood vessel connects (this process is the same with existing transfusion device), to close ball float 5 pours out in the ball storage chamber 4 and floats over that (ball storage chamber is higher than the liquid observing chamber liquid level on the medicinal liquid face, ball float can not roll out automatically, so need manually), the transfusion beginning; 3) when medicinal liquid is about to be totally lost, ball float 5 in liquid observing chamber 2 along with liquid level descends together, medicinal liquid in liquid observing chamber 2 is walked sky, and ball float sinks to ball sinking groove, makes ball float and ball sinking groove kissing by the effect of letting out power under external pressure, ball float deadweight and the transfusion device lower liquid.Close and form sealing, because of extraneous air can not enter, transfusion will stop automatically; 4) when connecting new medicinal liquid source once more, close manual-lock device 8, rise bag 7 with the hands extruding, impact ball float with liquid storage in the bag, (frictional force, the ball float that produces greatly because of the contact surface of ball float 5 and ball sinking groove 6 conducted oneself with dignity and the imprecision of turn-off transient has under a little liquid storage and lets out to make ball float on liquid level again, cause 5 times a small amount of inflations of ball float passive, in addition because of class of liquids, concentration difference, easily cause adhesion as viscosity such as saccharide, blood class are higher, ball float can not be risen freely), open closer 8, transfusion restarts.
On the operating position, described ball storage chamber 4 must be higher than the medicinal liquid face of operate as normal, and it is arranged on from the top of liquid observing chamber 2 one apart from a place, and this is about 1/4 of liquid observing chamber total height h apart from a.Usually liquid observing chamber total height h is about 60mm, and then a is about about 15mm.
To close ball float 5 when beginning to infuse in order making and to remain in the ball storage chamber 4, described ball storage chamber 4 is made to tubular, and tubular axis line t downward-sloping low-angle β on the operating position of ball storage chamber 4.
The described ball float 5 of closing is made by the material that can float on the medicinal liquid face or the water surface, and it can be sphere, and inverted cone is preferably spherical.
Automatically close in order to form more reliably, according to a kind of flexible program of the present utility model, this transfusion device can be made up of two above-mentioned transfusion device S polyphones, but only on the operating position their total bottom be provided with one and rise bag 7.
