In this utility model:
The slash pocket pin is the side opening pin, avoids fluid bag plug exfoliation.
Air pressure generator is made up of air bag and gas break-make switching valve simply and easily, gas break-make switching valve comprises spool and valve pocket, valve pocket is sleeved on the spool, spool has last lower channel, the lower channel communicated air bags, upper channel is communicated with the needle stand side and portals, and another stomidium of last lower channel is arranged side by side on valve core outer surface, valve pocket is provided with and is communicated with the interior groove mouth of going up lower channel other end hole, and the end of valve pocket is provided with outer groove mouth.When valve pocket is in spool one end, by outer groove mouth pressure generator is communicated with outside atmosphere, gas break-make switching valve is in closed condition, when another stomidium of the last lower channel in valve pocket is shifted onto on groove mouth and the spool is corresponding, air bag communicates with the flexible pipe that the needle stand side is portalled, and separate with outside atmosphere, gas break-make switching valve is in open mode.Air bag is made by elastoplast or rubber, can be shapes such as circle or ellipse.
End at spool connects filter, and the other end of filter connects the flexible pipe that the needle stand side is portalled, and filters the microgranule in the turnover powder bottle gas.
Under the normal condition, all be furnished with helmet on powder needle for inserting bottle and the slash pocket pin, guarantee safety.During use, after the helmet removal, the powder needle for inserting bottle inserts powder bottle, and the slash pocket pin inserts fluid bag.Make gas break-make switching valve be in closed condition, extruding gasbag, and then make gas break-make switching valve be in open mode, unclamp air bag, make and form negative pressure in the powder bottle, at this moment, liquid enters powder bottle in the fluid bag, powder is dissolved, extruding gasbag makes the interior liquid of powder bottle flow back to fluid bag by flexible pipe under positive pressure once more, closes gas break-make switching valve, after the powder needle for inserting bottle extracted, finish and make up a prescription.
The packed dispenser of the disposable use powder of this utility model, rational in infrastructure simple, molten medicine, make up a prescription easily, easy to operate, safe and reliable, be beneficial to and apply.
