Utility model content
The purpose of this utility model is to provide a kind of solid-liquid dual-purpose, reduces the medical micro-solid-liquid sampler of acquisition cost, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of medical micro-solid-liquid sampler, comprise body, piston and piston rod, piston is arranged in body and body is airtight being slidably connected, piston rod is connected to piston upper end, taper suction nozzle is provided with below described body, cylindricality suction nozzle is provided with below taper suction nozzle, cylindricality suction nozzle is set with mounting head, mounting head has capillary syring, capillary syring is provided with the suction pipe scale corresponding with its volume, tube wall is provided with the body scale corresponding with body volume, tube wall movable upper end is arranged with sleeve, body top outer wall is provided with back-up ring, described piston rod top is connected with push pedal, piston rod and push pedal center have post groove, straight-bar is equiped with in post groove, both sides, straight-bar top are provided with digs spoon, in push pedal, correspondence is dug spoon and is offered a spoonful groove, spoon groove two ends have half slot.
Further, described push pedal side is provided with connecting band, connecting band is provided with a spoonful groove lid.
Further, described mounting head is arranged with Straw cap.
Further, the tapered joint head that described mounting head is arranged by its lower end is connected with capillary syring.
Further, described sleeve adopts lucifuge material to make.
Further, described push pedal plane and back-up ring plane are provided with anti-skidding lines.
Compared with prior art; the beneficial effects of the utility model are: capillary syring is directly provided with suction pipe scale; avoid the trouble of the another bidding chi on suction pipe side; the situation that avoiding scale can make troubles to medical personnel when taking sample occurs; mounting head is arranged with Straw cap; Straw cap protects capillary syring, avoid capillary syring directly place in atmosphere easily contaminated or damage phenomenon occur.Be provided with in piston rod can be used for pressed powder sampling dig spoon, can sample fluid sample, can gather pressed powder again, reduce acquisition cost and maintenance cost.To sum up, this use new structure is simple, reasonable in design, all can gather sampling, facilitate the work of medical personnel to solid-liquid sample.
