Description
Technical field
This utility model relates to a kind of medical material, and more particularly, it relates to a kind of joint syringe for liquid medicine injection.
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, piston rod and syringe needle.Although this syringe makes simple, easy to use, but in use in order to the gas in syringe is drained only, need to promote piston rod, 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, in the domestic overall situation of the nowadays high cost of getting medical treatment, how to avoid liquid waste as much as possible, especially costly medicine, be significant, a lot of medicine, such as insulin, often an insulin requirement is with being for a long time just finished, if some insulins are all wasted in per injection, then when whole insulin is finished, the insulin proportion wasted is still quite high.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the joint syringe of the waste providing a kind of effective minimizing medicine that such as insulin and so on need be finished through multiple injection.
For achieving the above object, this utility model provides following technical scheme: a kind of joint syringe, comprise needle tubing, syringe needle and piston rod, described needle tubing sidewall is provided with dosing hole near syringe needle side roof part, described dosing hole is fixedly connected with exhaust apparatus, described exhaust apparatus comprises housing, calibration rotating cylinder, sliding grabbing is overlapped and spring, described sliding pawl overlaps one end sliding pawl, the other end is connected with button, described calibration rotating cylinder is provided with the calibration pawl matched with sliding pawl, deep trouth and shallow slot is had between calibration pawl, two kinds of grooves are staggered, described housing is provided with the guide rail raised line matched with deep trouth shallow slot, described sliding pawl puts the guide rail groove being provided with and matching with guide rail raised line, the below of described calibration rotating cylinder is fixedly connected with fixing head, described fixing head is fixedly connected with connecting rod, the other end of described connecting rod is fixedly connected with exhaust block, described spring is arranged between fixing head and housing, described dosing hole is identical with described syringe needle volume.
By adopting technique scheme, when using transfusion needle to carry out drawing liquid to medicine bottle herb liquid, needle tubing is stretched into the liquid, upwards pull piston rod, stop in time moving required medicinal liquid containing mark to, extract transfusion needle, now medicinal liquid is filled with dosing hole, by transfusion needle syringe needle upward, and prop up piston rod with hands, subsequently the button of exhaust apparatus is pressed, now pin inner air tube drains only, can directly inject, compared with existing syringe, bleeding before per injection all needs to waste some medicinal liquids, by carrying out bleeding before this exhaust apparatus per injection, because the volume of dosing hole is equal with syringe needle gas volume, gas in syringe can drain only by therefore each bleeding, the waste of medicinal liquid can not be caused.
This utility model is set to further: the diapire of described exhaust block is sealed by sealing ring and abuts with dosing hole inwall circumference.
By adopting technique scheme, the diapire of calibration rotating cylinder is sealed by sealing ring and abuts the sealing that can improve syringe with dosing hole inwall, prevents ambient atmos from flowing out from dosing hole inflow and pipe inner liquid medicine from dosing hole.
Further: housing is fixedly connected with dosing hole.
By adopting technique scheme, effectively can improve the stability of syringe, make exhaust apparatus more stable, aerofluxus is more accurate.
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, utilize dosing hole and exhaust apparatus fit structure, 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. 5, this utility model joint syringe embodiment is described further.
See Fig. 1 to 5, a kind of joint syringe, comprise needle tubing 2, syringe needle 1 and piston rod 3, described needle tubing 2 sidewall is provided with dosing hole 5 near syringe needle 1 side roof part, described dosing hole 5 is fixedly connected with exhaust apparatus 4, described exhaust apparatus 4 comprises housing 41, calibration rotating cylinder 44, sliding grabbing is overlapped and spring 45, described sliding pawl 53 overlaps 43 one end sliding pawl 53, the other end is connected with button 42, described calibration rotating cylinder 44 is provided with the calibration pawl 56 matched with sliding pawl 53, deep trouth 55 and shallow slot 54 is had between calibration pawl 56, two kinds of grooves are staggered, described housing 41 is provided with the guide rail raised line 48 matched with deep trouth 55 shallow slot 54, described sliding pawl 53 overlaps 43 and is provided with the guide rail groove matched with guide rail raised line 48, the below of described calibration rotating cylinder 44 is fixedly connected with fixing head 52, described fixing head 52 is fixedly connected with connecting rod 51, the other end of described connecting rod 51 is fixedly connected with exhaust block 49, described spring 45 is arranged between fixing head 52 and housing 41, described dosing hole 5 is identical with described syringe needle 1 volume.
