Description
Technical field
The utility model is related to medical instruments fields, more particularly to a kind of safety injection needle tubing.
Background technology
With the development of medical treatment, the case where people use injection, is more and more, when being injected at this stage, mostly uses greatly general
Cleansing pin cylinder, this common syringe cylinder structure is simple, has a single function.When extracting medicament using syringe, medicine absorbing tube is pricked into rubber
Plug cuts vial with grinding wheel, at this point, crumb of bottle stopper and glass powder can enter in medicament, reinjects in human body, can influence
To the physical and mental health of human body.Filter screen is added in existing syringe in Chinese patent 201210522911.1, to prevent foreign matter
Into syringe, although can solve foreign matter enters syringe, the medicament in syringe still will be injected into vivo, this
When, is attached to foreign matter on filter screen still and can enter internal, and there are personal safety hidden danger.
Invention content
The utility model provides a kind of safety injection needle tubing to overcome the shortcomings of above-mentioned technical problem, can be complete
Solve above-mentioned technical problem.
The technical solution for solving above-mentioned technical problem is as follows：
A kind of safety injection needle tubing, including housing, the upper front end of housing are arranged medicine absorbing tube, under the front end of the housing
Needle holder is arranged in portion, and the needle holder is connect with syringe needle, and the syringe needle one block of mating setting, the block is wrapped completely
It is overlying on the outside of needle holder and syringe needle, a baffle is axially arranged in middle part in the housing, and the baffle is jacket internal point
For upper and lower two decile, the upper core bar of baffle top setting, upper piston, the baffle is arranged in the front end of the upper core bar
The lower core bar of lower part setting, lower piston is arranged in the front end of the lower core bar, and the first mistake is arranged in housing leading inside top
The second filter membrane is arranged in filter membrane, the housing leading inside lower part, and the front end of the baffle and the front end of housing connect, when
When lower core bar is pulled to rearmost end, the rear end of baffle is located at the front side of lower piston.
Further, the mating one hygienic plug of setting of the medicine absorbing tube.
Further, the first cam, housing rear inside lower part setting second is arranged in the housing rear inside top
Cam.
The utility model is compact-sized, and block and hygienic plug ensure that the safe and healthy of syringe.First cam and
The setting of two cams ensure that core bar and lower core bar are not easy to pull out from housing during push-and-pull, avoid writing drug freely and easily
Object pollutes；For the baffle being axially arranged by needle tubing internal insulation at two channels, the drug of medicine absorbing tube inspiration needle tubing first is logical
It crosses the first filter membrane and filters out foreign matter, ensure to enter the drug safety in needle tubing, then lower core bar is pulled to rearmost end, allow drug edge
It baffle and flows to the lower part of needle tubing, then lower core bar is pushed to be injected, after drug is filtered again by the second filter membrane, protect
Cleanliness factor and the safety of the drug in injection human body are demonstrate,proved.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1 is housing, and 2 be medicine absorbing tube, and 3 be needle holder, and 4 be syringe needle, and 5 be block, and 6 be baffle, and 7 be upper core bar, 8
