Description
Technical field
This utility model relates to a kind of medical devices, and more particularly, it relates to a kind of syringe.
Background technology
Syringe is a kind of common medical instruments, be made up of the foraminate syringe of front end band and the piston core bar that matches, syringe is used for a small amount of liquid or its to be injected into region that other method cannot be close or locally extracts out from those, when core bar is extracted, liquid or gas suck from syringe front end aperture, when core bar pushes, liquid or gas are extruded, injection is called, mainly in order to liquid medicine injection or drawing liquid by this process of syringe and syringe needle extraction or injecting gas or liquid.
At present, the syringe on market, it comprises syringe, syringe piston, syringe needle and pin lid.Although this syringe makes simple, easy to use, but in use in order to the gas in syringe is drained only, need pushing syringe piston, after medicinal liquid penetrates from syringe needle, could by residue injecting liquid drug in human body or animal, this process can cause the liquid waste of injection, medicine is more valuable, loses more.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of medicinal liquid callable syringe.
For achieving the above object, this utility model provides following technical scheme: a kind of syringe, comprise syringe, syringe piston, syringe needle and pin lid, described pin lid comprises liquid collector, described liquid collector is provided with through hole, through hole one end is stifled is provided with rubber closure, and the other end of described through hole is provided with aqueous vapor diffusion barrier, forms liquid collecting cavity between aqueous vapor diffusion barrier and rubber closure.
By adopting technique scheme, when using this syringe, syringe needle is inserted in the medicine bottle of required injection, pull syringe piston, medicinal liquid can be pumped in needle tubing, subsequently syringe needle is extracted from medicine bottle, now existing medicinal liquid in syringe, also gas is had, now syringe needle is inserted in liquid collecting cavity from the rubber closure end of liquid collector, pushing syringe piston, air in syringe needle and part medicinal liquid enter liquid collecting cavity, continue pushing syringe piston, air in liquid collecting cavity can be discharged from outlet chamber through aqueous vapor diffusion barrier, syringe piston is pulled after cannot promoting piston, liquid collecting cavity inner liquid medicine is by suction needle tubing again, syringe is extracted after medicinal liquid is drained, now just only has medicinal liquid in syringe and syringe needle, there is not gas, can directly inject.
This utility model is set to further: described liquid collector is socketed with Ka Gai near described aqueous vapor diffusion barrier side, and described Ka Gai abuts with described aqueous vapor diffusion barrier.
By adopting technique scheme, after the medicinal liquid complete set in liquid collecting cavity is full, Jiang Kagai is set on liquid collector, then extracts medicinal liquid, in the process extracting medicinal liquid, prevent gas from entering in liquid collecting cavity, thus impact is taken out in medicine process and may be occurred that gas is by suction syringe again.
Further: described pin lid adopts transparent material to make.
By adopting technique scheme, pin lid employing transparent material is made and medical worker can be made to know about pin lid inner case when being exhausted, control syringe piston push-and-pull speed that can be suitable, it also avoid when syringe needle inserts and causes damage to aqueous vapor diffusion barrier.
Further, described aqueous vapor diffusion barrier can arrange multilamellar.
By adopting technique scheme, aqueous vapor diffusion barrier arranges multilamellar and makes liquid collecting cavity isolation medicinal liquid effect better, avoids syringe needle simultaneously and accidentally injures the liquid collecting exhaust effect that aqueous vapor diffusion barrier affects liquid collecting cavity.
Further, the spacing of described aqueous vapor diffusion barrier and rubber closure exposure air side is not less than needle length.
By adopting technique scheme, when syringe needle is inserted in liquid collecting cavity, syringe needle can not be made to destroy aqueous vapor diffusion barrier.
Further, described Ka Gai adopts airtight flexible material to make.
By adopting technique scheme, after Ka Gai abuts with aqueous vapor diffusion barrier, when extracting liquid collecting cavity inner liquid medicine, air can not enter liquid collecting cavity from outlet chamber, and soft Ka Gai reduces the damage to aqueous vapor diffusion barrier.
Compared with prior art, the utility model has the advantage of: the waste that can cause medicinal liquid in the exhaust process of different syringe in the past before injecting, utilization can the needle cover of aerofluxus liquid collecting, achieve syringe and do not waste medicinal liquid in aerofluxus, improve the utilization rate of medicinal liquid, reduce waste, alleviate patient economy burden.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, this utility model syringe embodiment is described further.
See Fig. 1 to 3, a kind of syringe, comprise syringe 1, syringe piston 2, syringe needle 3 and pin lid 4, described pin lid 4 is made up of liquid collector 41 and Ka Gai 42, described liquid collector 41 is provided with through hole, through hole one end rubber closure 412 seals, and is just provided with aqueous vapor diffusion barrier 411 to rubber closure 412 in the middle part of described through hole, forms liquid collecting cavity between aqueous vapor diffusion barrier 411 and rubber closure 412.
See Fig. 1, when needing the gas in syringe 1 to discharge, syringe needle 3 is inserted in the medicine bottle of required injection, pull syringe piston 2, medicinal liquid can be pumped in needle tubing, subsequently syringe needle 3 is extracted from medicine bottle, now existing medicinal liquid in syringe 1, also gas is had, now syringe needle 3 is inserted in liquid collecting cavity from rubber closure 412 end of liquid collector 41, then card lid 42 is taken off, pushing syringe piston 2, air in syringe needle 3 and part medicinal liquid enter liquid collecting cavity, continue pushing syringe piston 2, air in liquid collecting cavity can be discharged from outlet chamber through aqueous vapor diffusion barrier 411, after cannot promoting piston, card lid 42 covered outlet chamber and abut with aqueous vapor diffusion barrier 411, pull syringe piston 2 subsequently, liquid collecting cavity inner liquid medicine is by suction needle tubing again, syringe is extracted after medicinal liquid is drained, now just only has medicinal liquid in syringe 1 and syringe needle 3, there is not gas, can directly inject, consider the intensity of syringe 1 and syringe piston 2, syringe 1 and syringe piston 2 can adopt transparent polypropylene (PP) material to make.
See Fig. 2, when this syringe is not by use, be inserted in liquid collecting cavity by the syringe needle 3 of syringe from rubber closure 412 one end of pin lid 4, this hour hands lid 4 pairs of syringe needles 3 play a protective effect.
See Fig. 3, be provided with aqueous vapor diffusion barrier 411 in liquid collector 41, liquid collector 41 one end rubber closure 412 seals, and other end card lid 42 seals, and card lid 42 abuts with aqueous vapor diffusion barrier 411.Consider the intensity of liquid collector 41, weight and visuality, liquid collector 41 adopts transparent polypropylene (PP) material to make, card lid 42 considers flexibility and sealing, card lid 42 can be rubber closure 412, the beautiful board gas-liquid separation membrane in the east that aqueous vapor diffusion barrier 411 adopts Rui Sen waterproof ventilative material company limited to produce.
It should be noted that, card lid 42 can also be clamping with the connection of liquid collector 41, grafting etc., but the sealing considering liquid collecting cavity herein, preferably adopts card lid 42 to abut with aqueous vapor diffusion barrier 411.
