Meanwhile, assembling is simple and convenient, and cost is low.
Description
Technical field
The present invention relates to a kind ofly carry out the venous transfusion medical apparatus and instruments to clinical patients, specifically a kind of automatic liquid-stopping transfusion apparatus.
Background technology
Various automatic liquid-stopping valve transfusion devices have appearred in the transfusion device that uses clinically at present, there is a kind of software thin film of buoyancy aid lower end setting that relies on seal the liquid outlet in dropping funnel and then stop liquid in prior art, have certain sealing effectiveness, but have potential safety hazard.
For example the Chinese patent CN201220386251.4 of inventor application discloses an a kind of safety automation liquid-controlled open-close valve and has had the transfusion device of this safety automation liquid-controlled open-close valve, wherein said safety automation liquid-controlled open-close valve is placed in dropping funnel, comprise: valve body, valve gap, upper float and seal; Described valve body comprises a frustum section, and the liquid outlet on described valve body is fixedly connected with liquid outlet in dropping funnel; Described valve gap center is provided with the through hole that the buoyancy aid connecting rod passes through, and described valve gap snaps onto on valve body; Described upper float is connected with the buoyancy aid connecting rod of seal by hollow, and described upper float is placed in outside valve body; Described seal is frustum, is placed in valve body; Wherein, the sealing surface on described seal contacts with inclined-plane on valve body frustum section and realizes sealing.Above-mentioned prior art proposes the concept of inclined-plane sealing, simultaneously as far as possible utilize the construction features of valve body, make sealing effectiveness be better than other seal or sphere film body.In the disclosed specific embodiment of above-mentioned technology, seal and seal connector coordinate when installing a cavity volume, has namely increased buoyancy, also be convenient to install seal, but in practice, during assembling seal, guarantee as far as possible sealing member bottom surface maintenance level, preferably do not stress; In any case install, a little air of film cavity total meeting contain, film chamber and extraneous some pressure reduction that exist cause the bottom of sealing member just can not be in a horizontal plane, and sealing effectiveness can detract; If external pressure is greater than the film intracavity of seal, the sealing member bottom is concavity; If external pressure is less than the film intracavity of seal, the sealing member bottom is convex; The imbalance of pressure inside and outside this moment affects sealing effectiveness and stops the liquid effect; Under the prerequisite that can't guarantee sealing member bottom surface level, will require the plane precision of film highly especially, so just increased manufacturing cost.
The sealing effectiveness that how to solve sealing member is puzzlement research staff's main bugbear always.
Summary of the invention
The present invention aims to provide a kind of automatic liquid-stopping dropping funnel that can regulate the outer pressure of film intracavity.
