Abstract
The utility model discloses a kind of monocoque storage blood device positive/negative-pressure relief valve, comprise housing (1) and spool (2), it is characterized in that: described housing (1) upper end is provided with negative pressure inlet mouth (3), described spool top is provided with duckbill positive pressure ventilation valve (4), bottom is provided with umbrella negative pressure inlet valve (5), and this monocoque storage blood device positive/negative-pressure relief valve is connected with monocoque storage blood device.
Description
Technical field
This utility model relates to a kind of storage blood device, especially a kind of relief valve be used on storage blood device.
Background technology
In operation process; usually various monocoque storage blood device (bucket, storehouse) can be used; need the Blood storing and filtering device of perfect in shape and function for use clinically; but the Blood storing and filtering device used clinically at present all goes back the problem that ubiquity gravity inadequate drainage, to patient safety poor performance.
Summary of the invention
This utility model thinks highly of the problem of power inadequate drainage to overcome monocoque storage blood in prior art, a kind of simple and reasonable monocoque storage blood device positive/negative-pressure relief valve is provided, use the monocoque of this relief valve to store blood device and namely may be used for gravity drainage, also may be used for Negative Pressure Assist Drainage, not by the restriction of surgical condition.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of monocoque storage of this utility model blood device positive/negative-pressure relief valve, comprise housing and spool, described housing upper end is provided with negative pressure inlet mouth, described spool top is provided with duckbill positive pressure ventilation valve, bottom is provided with umbrella negative pressure inlet valve, and this monocoque storage blood device positive/negative-pressure relief valve is connected with monocoque storage blood device.
This utility model adopts said structure, monocoque storage blood device may be used for gravity drainage, also monocoque can be store blood device to be connected with negative pressure source, implement Negative Pressure Assist Drainage, not by the restriction of surgical condition, when in monocoque storage blood device, malleation or negative pressure exceed design load, duckbill air bleeding valve or umbrella intake valve are opened automatically, balance storehouse inner and outer air pressure.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
