Description
Technical field
This utility model relates to technical field of medical instruments, injects pin in particular for premunitive new generation vaccine.
Background technology
In prophylactic immunization clinically, the vaccine syringe used at present is common disposable syringe, does not carry out specialized designs for prophylactic immunization.When vaccination, the principle of " Miao Suibing is capable, the complete ice of Seedling " in use procedure, must be followed, forbid multigelation, otherwise will vaccine failure be caused.Disposable syringe is used to inoculate, in the pin chamber of entry needle, inevitably leave a certain amount of vaccine remain, cause vaccine utilization rate low, be vaccinated people and can not get enough vaccines, cause prophylactic immunization failure, bring unnecessary loss and misery to inoculation people.
Notification number is a kind of constant temperature vaccination device of CN204501946U, by setting up vaccine chamber, and adopt the double-decker (storage mixture of ice and water) of hollow, managing vaccine cavity temperature perseverance is 0 DEG C, thus improves vaccine utilization rate, guarantee vaccine effect.But limitting by its structure, mixture of ice and water necessity submits to fill at the vaccine intracavity of hollow, wants to keep 0 DEG C for a long time, can only leave in cold closet by syringe entirety, take inconvenience; Simultaneously, the joint in the boss in its structure and vaccine chamber is also unreasonable, when boss front end enters vaccine chamber, pintle is the pin chamber blocked inlet of puncture needle, the vaccine liquid that vaccine intracavity remains can not continue the pin chamber entering puncture needle, can not realize said effect of avoiding retaining in chamber vaccine in patent announcement file at all.
Utility model content
The purpose of this utility model is provided for premunitive new generation vaccine injects pin to overcome above-mentioned technical disadvantages, solve vaccine part in puncture needle residual, can not the problem of 0 DEG C of constant temperature method.
The technical scheme that this utility model technical solution problem adopts is: inject pin for premunitive new generation vaccine, comprise syringe, puncture needle, piston head, push rod, promote mainly handle, pintle and auxiliaryly push away handle, described syringe is the sandwich of double-deck barrel, described puncture needle is fixed by lock plunger and syringe front end, piston head is provided with in syringe, described piston head is post frustum structure, syringe interior forward end is drawn in and is mated with piston head front end is suitable mutually, piston head rear end face connects push rod, putting back-end connects promotes mainly handle, push rod hollow and inside wears a pintle, pintle front end penetrates piston head and passes along its axis, pintle rear end penetrates to promote mainly handle and connect and auxiliaryly pushes away handle, described back end of syringe is provided with protruding ring, two fluid-through tubes are arranged with relative to the axis of syringe outside ring, wherein a fluid-through tube connects feed tube, another root fluid-through tube connects drain pipe, feed tube, drain pipe pours into respectively in the sandwich of syringe, discharge mixture of ice and water.Piston head is used for the vaccine liquid in syringe to release through puncture needle, when piston head front end is butted on syringe interior forward end, pushes away the pin intracavity that pintle to be pushed puncture needle by handle, released by vaccine liquid remaining for pin intracavity, solve the problem that vaccine liquid is remaining by auxiliary; Mixture of ice and water after the hollow cavity of double-deck double wall that feed tube enters syringe, then is discharged through drain pipe, circulates and lower the temperature to the vaccine liquid of syringe inside, solves the problem of vaccine 0 DEG C maintenance constant temperature.
Pintle rear end in described push rod is provided with limited block, the distance that the distance of limited block and pintle front end is more than or equal to piston head front end face and promotes mainly between handle.Limited block with promote mainly handle touch time, the front end of pintle is stretched out the front end face of piston head or flushes with piston head front end face, avoids vaccine liquid to enter push rod through piston head.
The described centre promoting mainly handle piston head side is dorsad provided with localizer, localizer with promote mainly handle and be fixedly connected with and be socketed in pintle outside, promote mainly handle, localizer is provided with the locating slot coincided, pintle is provided with and the locating slot suitable positioning strip mated mutually.Localizer ensures that pintle is on the axis of syringe all the time on the one hand, the bending when the pin chamber of puncture needle is stretched in pintle front end is avoided to be out of shape or to fracture, on the other hand, when positioning strip does not embed in locating slot, auxiliaryly push away handle, pintle cannot driven forward, block vaccine liquid after pintle being pushed when avoiding piston head not yet to inject the pin chamber of puncture needle and enter.
The beneficial effect that this utility model has is: this utility model reasonable in design, end spaces before the piston head reduction piston cylinder of employing post frustum structure, mixture of ice and water is utilized to keep 0 DEG C of constant temperature at cavity internal recycle, pintle injects the vaccine liquid of puncture needle intracavity further, improve vaccine utilization rate, ensure low-temperature operation, improve inoculation efficiency and effect.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of localizer described in the utility model.
Detailed description of the invention
Be described below below in conjunction with accompanying drawing 1, accompanying drawing 2 pairs of this utility model.
