Description
Technical field
This utility model relates to and a kind ofly carries out the venous transfusion medical apparatus and instruments to clinical patients, a kind of specifically liquid transfusion device that ends automatically.
Background technology
The various liquid valve transfusion devices that end have automatically 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 to seal the liquid outlet in the dropping funnel and then end liquid in the prior art, have certain sealing effectiveness, but have potential safety hazard.
For example the Chinese patent CN201220386251.4 of inventor's application discloses the transfusion device that a kind of one safe automatic hydraulic opens and closes valve and has this safe automatic hydraulic keying valve, wherein said safe automatic hydraulic opens and closes valve and places in the dropping funnel, comprise: valve body, valve gap, upper float and seal; Described valve body comprises a frustum section, and the liquid outlet on the described valve body is fixedlyed connected with the liquid outlet in the 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 the valve body; Described upper float is connected with the buoyancy aid connecting rod of seal by hollow, and described upper float places outside the valve body; Described seal is frustum, places in the valve body; Wherein, the sealing surface on the described seal contacts with inclined-plane on the valve body frustum section and realizes sealing.Above-mentioned prior art proposes the notion 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 cooperate when installing a cavity volume, has promptly increased buoyancy, also be convenient to install seal, but in practice, during assembling seal, guarantee that as far as possible the sealing member bottom surface keeps level, does not preferably 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 influences sealing effectiveness and ends the liquid effect; Under the prerequisite that can't guarantee sealing member bottom surface level, will be high especially to the plane precision requirement of film, so just increased manufacturing cost.
The sealing effectiveness that how to solve sealing member is puzzlement research staff's a main difficult problem always.
