Abstract
The invention discloses a medical liquid discharge valve, and belongs to the technical field of medical equipment accessories. The medical liquid discharge valve comprises a valve body and a piston, wherein a liquid inlet and a liquid outlet are arranged on the valve body in extending modes, the piston is arranged in a valve body cavity, the piston comprises a first piston segment, a second piston segment and a connecting pillar, one end of the connecting pillar is connected with the center of one end face of the first piston segment, the end face of the first piston segment faces towards the second piston segment, the other end of the connecting pillar is connected with the center of one end face of the second piston segment, the end face of the second piston segment faces towards the first piston segment, a first plug column is placed in a cavity of the first piston segment, and a second plug column is placed in a cavity of the second piston segment. The medical liquid discharge valve has the advantages of being reliable in connecting with a liquid discharge connecting port on a drainage bag or a drainage bottle, capable of being operated by a single hand so that convenience of use is reflected, and extremely simple in integral structure.
Description
Technical field
the invention belongs to medical devices accessory technical field, be specifically related to a kind of medical bleeder valve, matched for the tapping interface with drainage bag or drainage bottle.
Background technology
as the reason known to those of skill in the art, be typically provided with tap hole (also claiming leakage fluid dram) at drainage container on as drainage bag, drainage bottle, when the full liquid of drainage container and need except the time, the gag of open configuration on tap hole, on the contrary the gag lid is closed in tap hole.
the shortcoming that said structure exists is: the obturation effect of gag and tap hole can not reach gratifying degree, and especially the easy improper emersion from tap hole of gag, cause the interior drainage-fluid environmental pollution of drainage container; Use inconvenience.
the applicant retrieves, yet be showed no all technology enlightenments that is made up aforementioned shortcoming that has in published China and foreign countries patent and non-patent literature, the applicant has done useful design for this reason, and technical scheme described below produces under this background.
Summary of the invention
task of the present invention is to provide a kind of reliable keying effect of the liquid outlet that contributes to ensure drainage bag and medical bleeder valve easy to use and simple in structure.
task of the present invention completes like this, and a kind of medical bleeder valve, comprise a valve body, is extended with a feed liquor interface and and goes out liquid interface on this valve body, and the liquid inlet and outlet interface communicates with the valve body chamber of valve body each other on same axis and all, one piston, be arranged on described valve body intracavity, this piston comprises the first piston sections, the second piston sections and joint pin, one end of joint pin is connected with the central authorities of first piston sections towards an end end face of the second piston sections, and the other end of joint pin is connected with the central authorities of the second piston sections towards an end end face of first piston sections, be provided with the first stick harness in the cavity volume of first piston sections, and be provided with equally the second stick harness in the cavity volume of the second piston sections, when described joint pin corresponding to described feed liquor interface and while going out between liquid interface, advance, the passage gone out between liquid interface communicates, when first piston sections or the second piston sections corresponding to advancing, while going out between liquid interface, advance, go out the pathway closure between liquid interface.
technical scheme provided by the invention by first, second piston sections of the piston of play back and forth to the passage opening and closing of fault between the liquid inlet and outlet interface, not there will be the improper keying phenomenon under non-artificial effect, with the tapping interface on drainage bag or drainage bottle, connect reliably, and can one-handed performance and embody the convenience of use, overall structure is very simple.
The accompanying drawing explanation
fig. 1 is the embodiments of the invention structure chart.
The specific embodiment
refer to Fig. 1, the valve body 1 provided is preferably used transparent plastic or transparent lucite to make, be extended with respectively a feed liquor interface 11 and and go out liquid interface 12 on this valve body 1 and in corresponding position, shown in figure, liquid inlet and outlet interface 11,12 each other on same longitudinal axis, and all communicates with the valve body chamber 13 of valve body 1.
the piston 2 be arranged in valve body chamber 13 provided consists of first, second piston sections 21,22 and joint pin 23, the three forms the structure of dumbbell shaped, one end of joint pin 23 is connected with the central authorities of first piston sections 21 towards an end end face of the second piston sections 22, and the other end of joint pin 23 is connected with the central authorities of the second piston sections 22 towards an end end face of first piston sections 21.Fill out in the cavity volume of first piston sections 21 and be provided with the first stick harness 211, same, fill out in the cavity volume of the second piston sections 22 and be provided with the second stick harness 221.
take the location status shown in current Fig. 1 as example, when acting on first piston sections 21 and make it to left dislocation and make joint pin 23 corresponding to aforesaid liquid inlet and outlet interface 11,12, the passage between liquid inlet and outlet interface 11,12 just communicates, when so to left dislocation and while making first piston sections 21 corresponding to liquid inlet and outlet interface 11,12, the channel enclosed between liquid inlet and outlet interface 11,12; With example, when acting on the second piston sections 22 and make its displacement to the right and make joint pin 23 corresponding to aforesaid liquid inlet and outlet interface 11,12, the passage between liquid inlet and outlet interface 11,12 communicates, when so displacement to the right while making the second piston sections 22 corresponding to liquid inlet and outlet interface 11,12, the channel enclosed between liquid inlet and outlet interface 11,12.Visible, as long as user, singlehanded to piston 2 effects, just can play the effect of above-mentioned handled easily.
aforesaid feed liquor interface 11 connects as the tapping interface on drainage bag or drainage bottle with drainage container in use.Only have when tapping, just make joint pin 23 corresponding between liquid inlet and outlet interface 11,12.
