Abstract
The invention relates to a bubble-proof transfusion device, comprising a dripping pipe (1), a dripping bucket (2), medical liquid (3), a bubble proof pipe (40) and a duct (5); wherein the bubble-proofpipe (40) is sealed at the upper part and provided with at least two notches (41) at a cylindrical side. The invention has the advantages that bubble in the medical liquid is prevented from entering the duct, degassing operation time during clinic transfusion is greatly shortened, and the transfusion speed during transfusion requiring a large amount can be enhanced due to vacuum negative pressurein the pipe as designed, thereby meeting the clinic first-aid effect.
Description
Technical field
The present invention relates to a kind of transfusion device, relate 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
The technical issues that need to address of the present invention 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, the present invention is achieved by the following technical solutions:
The present invention includes: 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 invention has the beneficial effects as follows: 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.

Fig. 2 is an anti-bubble tubular construction sketch map among Fig. 1;
Fig. 3 is a structural representation of the present invention;
Fig. 4 is an anti-bubble tubular construction sketch map among Fig. 3;

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
By Fig. 3, Fig. 4, Fig. 5 as seen: the present invention includes: 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.
Operation of the present invention and general infusion set are basic identical, 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.
The present invention 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 the present invention 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 (2)
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.
