Abstract

The utility model relates to an anti-bubble transfusion system, which comprises a pipette (1), a dripping bucket (2), liquor (3), an anti-bubble tube (40) and a guiding pipe (5); wherein, the anti-bubble tube (40) is provided with a top seal and at least two notches (41) at the cylindrical side; the utility model has the advantages of preventing the air buddle in the liquor from entering into the guiding pipe and greatly shortening the time of air bubble operation during clinical transfusion; the vacuum action in the tube during the design can help to increase the transfusion speed in dire need of much transfusion and can satisfy the effect of clinical fire aid.

Description

Bubble-proof transfusion device

Technical field

This utility model relates to a kind of transfusion device, relates in particular to the anti-bubbler tube in dropping funnel in this transfusion device.

Background technology

Disposable transfusion device be a kind of in medical treatment and nursing is used patient's employed product of infusing.

As seen from Figure 1: transfusion device is made up of dropper 1, dropping funnel 2, medicinal liquid 3, anti-bubbler tube 4, conduit 5; Wherein anti-bubbler tube 4 communicates with conduit 5, and conduit 5 links to each other with transfusion needle (not drawing among the figure).

As seen from Figure 2: anti-bubbler tube 4 is column type pipes of a upper opening.In order to solve anti-bubble purpose, must carry out artificial aerofluxus: earlier with the dropping funnel reversal of the natural order of things, treat that liquid is crossed the anti-bubbler tube mouth of pipe after, dropping funnel is just hung, just reach anti-bubble purpose, the long and complex operation of operating process brings great inconvenience for medical worker and patient like this.

Summary of the invention

This utility model technical issues that need to address have provided a kind of bubble-proof transfusion device, are intended to solve above-mentioned defective.

In order to solve the problems of the technologies described above, this utility model is achieved through the following technical solutions:

This utility model comprises: dropper, dropping funnel, medicinal liquid, anti-bubbler tube, conduit; Described anti-bubbler tube is that the notch more than at least two is sealed, has on the side side of column type on a top.

Compared with prior art, the beneficial effects of the utility model are: stop the bubble in the medicinal liquid to enter in the conduit, and the bleeding time when shortening clinical transfusion greatly; Also, more can when being badly in need of a large amount of transfusion, increase transfusion speed, satisfy clinical rescue effect because of negative pressure of vacuum effect in the pipe in the design.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:

By Fig. 3, Fig. 4, Fig. 5 as seen: this utility model comprises: dropper 1, dropping funnel 2, medicinal liquid 3, anti-bubbler tube 40, conduit 5; Described anti-bubbler tube 40 is that the notch 41 more than at least two is sealed, has on the side side of column type on a top.

Described notch 41 more than at least two is three.

This utility model operation is basic identical with general infusion set, but need not artificial aerofluxus, and evacuation time is no more than 10 seconds, (common tube is generally more than 30 seconds).Its action principle be when the bubble in the liquid when flowing through the narrow slit of anti-bubbler tube, because of the surface tension of bubble is stopped in outside the anti-bubbler tube, can not continue to flow into infusion pipeline.

This utility model has utilized the surface tension of liquid and gas and the principle of dynamics of water, and combined effect reaches the first aerofluxus body effect of aerofluxus liquid again, becomes the state of negative pressure of vacuum when gas has been arranged in the full pipe, makes current accelerate (being more than 8 times of common tube).

During operation this utility model is connected on the medicinal liquid bottle, medicinal liquid is in dropper enters dropping funnel, and medicinal liquid enters conduit and transfusion needle through anti-bubbler tube.Because the surface tension effects of liquid and gas, medicinal liquid is an aerofluxus body when being lower than anti-bubbler tube, and when medicinal liquid rises when being higher than anti-bubbler tube, because formation negative pressure of vacuum effect in the dropping funnel, liquid enters conduit.Form and observe for the ease of drop, certain space must be arranged below the dropper, so anti-bubbler tube must be longer than dropper.

Claims

1. a bubble-proof transfusion device comprises: dropper (1), dropping funnel (2), medicinal liquid (3), anti-bubbler tube (40), conduit (5); It is characterized in that: described anti-bubbler tube (40) be that seal on a top, at the other notch (41) that has more than at least two of the side of column type.

2. bubble-proof transfusion device according to claim 1 is characterized in that: described notch (41) more than at least two is three.
