Abstract
The utility model relates to an air discharge device connected with a dropper, which is used in an anti-bubble infusion apparatus. The air discharge device comprises a dropper, a dropper upper cover connected with the dropper, and a guide pipe connected with the dropper upper cover. The air discharge device also comprises an air filter; an air film with waterproofing effect is arranged on the guide pipe; and the guide pipe is inserted into the dropper and is positioned above an anti-bubble pipe and is spaced with the anti-bubble pipe at a distance. The air discharge device arranged on the dropper quickens air discharge speed, stabilizes the liquid flowing into the dropper and prevents formation of an air bubble-liquid mixture, so as to achieve an anti-bubble effect.
Description
Technical field
This utility model relates to a kind of transfusion device, relates in particular to the exhaust apparatus that links to each other with dropping funnel in this transfusion device.
Background technology
Existing clinically the transfusion device of being applied to is by bottle plug puncture unit, conduit, dropping funnel, flow regulator and venoclysis needle constitute, by above-mentioned transfusion device when initial the use, dropping funnel need be inverted or be pinched the sequence of operations such as form of bullet conduit and could get rid of unnecessary gas, if misoperation, enter downcomer after can causing a large amount of liquids and gases to mix and form bubble liquid, influence infusion process, as not finding because of carelessness, may damage even fatal human body, complex operation in getting rid of these bubble processes, reduce labor efficiency, also waste medicinal liquid simultaneously.
As shown in Figure 1 and Figure 2: anti-bubbler tube 40 is that the notch 41 more than at least three is sealed, has on the side side of column type on a top.When medicinal liquid flows into dropping funnel, under the situation that is lower than anti-bubbler tube, because the surface tension effects of liquid, liquid that can not flows out dropping funnel from the notch of anti-bubble, and along with liquid level rises, three notches all are closed, because the continuing of liquid splashes into, the dropping funnel internal pressure strengthens, and greater than surface tension, liquid is fast from the notch inflow catheter.
Arrive in the process of dropping funnel owing to pass through bottle plug puncture unit and conduit at liquid in the use, there are bubble or space in the above-mentioned pipeline, cause unstable liquid stream or impingement flow, the liquid that accumulates in the dropping funnel also has bubble retention or gas liquid mixture, these bubbles and gas liquid mixture can flow into downcomer from anti-bubble tube seat mouth along with liquid, because dropping funnel internal pressure effect, it is very fast to begin to enter the liquid velocity of preventing the bubble tube cavity, cause and have space formation in the tube chamber, along with the continuation of liquid is flowed out, space meeting full of liquid, the gas in the space can form bubble along with liquid enters downcomer, because it is slower that above-mentioned situation occurs, the nurse takies the more time in processing procedure, influenced whole infusion process, has also wasted medicinal liquid simultaneously, if do not find bubble, can cause fatal harm to patient.
Summary of the invention
This utility model technical issues that need to address have provided the exhaust apparatus that links to each other with dropping funnel in a kind of bubble-proof transfusion device, are intended to solve the above problems.
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: the dropping funnel loam cake of dropping funnel, connection and dropping funnel; Be connected with conduit at the dropping funnel loam cake; Also comprise: the air filter that on conduit, is provided with the resistance effect air film; Conduit inserts and is positioned at anti-bubbler tube top in the dropping funnel and with anti-bubbler tube distance is arranged.
Compared with prior art, the beneficial effects of the utility model are: owing on dropping funnel, added exhaust apparatus, the deflated speed of quickening, the liquid that flows into dropping funnel is steady, and the gentle liquid mixture of no bubble forms, and reaches anti-bubble effect.
Description of drawings
Fig. 1 is the anti-bubble tubular construction sketch map that China Patent No. 200720076629.X, name are called bubble-proof transfusion device;
Fig. 2 is an A place enlarged drawing among Fig. 1;
Fig. 3 is this utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail:
As seen from Figure 3: this utility model comprises: the dropping funnel loam cake 2 of dropping funnel 1, connection and dropping funnel; Be connected with conduit 4 at dropping funnel loam cake 2; Also comprise: the air filter 5 that on conduit 4, is provided with the resistance effect air film; Conduit 4 inserts and is positioned at anti-bubbler tube 40 tops in the dropping funnel and with anti-bubbler tube 40 distance is arranged.
When medicinal liquid flows into dropping funnel, owing on dropping funnel, added exhaust apparatus, the deflated speed of accelerating, gas is got rid of fast in the dropping funnel, liquid flows into dropping funnel and speeds up, because conduit is above anti-bubbler tube, rise to air filter 5 along conduit when liquid rises to conduit, owing to be provided with the resistance effect air film, liquid stops to rise, along with liquid in the dropping funnel continues to splash into, pressure increases, and liquid flows into downcomer along the notch of anti-bubbler tube, and the liquid that flows into dropping funnel is steady, the gentle liquid mixture of no bubble forms, and reaches anti-bubble effect.
Claims (1)
