Abstract
The invention discloses a pneumatic boosting injector, mainly comprising an empty cylinder, a piston shaft, a piston A and a piston B, wherein the empty cylinder is a standard injector empty cylinder; the piston A is arranged in the empty cylinder; the piston B is arranged outside the empty cylinder; an abandoning joint is arranged on the piston shaft, and two ends of the abandoning joint are the same in structure and can be both tenon-jointed with a T-shaped hole in a rubber piston; the piston A is completely identical to the piston B; the piston A and the piston B are arranged at two ends of the piston shaft; the length of the piston shaft can meet the condition that the piston B is positioned outside the empty cylinder when the piston A is butted against the bottom part of the empty cylinder. The pneumatic boosting injector has the advantages that a piston handle of the traditional single-piston injector is replaced by a rubber piston, so that the rubber piston can be used by matching boosting manipulation equipment, therefore, on one hand, the working efficiency is improved; on the other hand, the labor intensity of medical personnel is greatly reduced, and people enjoy a better medical service.
Description
Technical field
The present invention relates to a kind of syringe, especially a kind of air assisted syringe.
Background technology
With growth in the living standard, the consciousness that people to hospital seek medical advice is more and more stronger, particularly large hospital, beats daily and hangs
The people of pin is hundreds and thousands of, and traditional syringe makes the medical personnel making up a prescription thick because the work of high intensity leads to have risen on hand
Callus, even bleeding blister, not only labor efficiency substantially reduce, if things go on like this also can cause employment injuries to the handss of labourer.
Content of the invention
The technical problem to be solved is to provide a kind of air assisted syringe, and existing tradition single-piston formula is noted
The piston handle of emitter is changed to rubber piston, and matched power-assisted controlling equipment is provided with the gas being adapted with rubber piston
Cylinder, can make rubber piston move back and forth wherein by controlling the positive and negative air-pressure in cylinder, drive syringe work.
The technical scheme that the present invention solves its technical problem is: a kind of air assisted syringe, main inclusion sky cylinder, piston
Axle, piston a and piston b, described sky cylinder is standard syringe sky cylinder, and, in described sky cylinder, described piston b is in institute for described piston a
State outside empty cylinder.
Described piston shaft is provided with scraps knot, and two-end structure is identical, can close with the t shape hole tenon on rubber piston.
Described piston a is identical with described piston b, piston shaft two ends described in office.
The length of described piston shaft can make when described piston a pushes up the bottom of described sky cylinder, and described piston b is in institute
State outside empty cylinder.
The invention has the beneficial effects as follows, compared with prior art, double-piston syringe can by the strength of controlling equipment,
Lifting work efficiency, reduces labor intensity, people can be allowed to enjoy more preferable medical services, greatly reinforced to medical care people again
The labor protection of member.

Fig. 1 is overall structure diagram of the present invention.
Fig. 2 is inventive piston system structure diagram.
Fig. 3 is power-assisted controlling equipment overall structure diagram of the present invention.
Specific embodiment
As illustrated, a kind of air assisted syringe, main inclusion sky cylinder 1, piston shaft 2, piston a3 and piston b4, described
Empty cylinder 1 is standard syringe sky cylinder, and, in described sky cylinder 1, described piston b4 is outside described sky cylinder 1 for described piston a3.Described work
Plug axle 2 is provided with scraps knot, and two-end structure is identical, can close with the t shape hole tenon on rubber piston.Described piston a3 and institute
State piston b4 identical, piston shaft 2 two ends described in office.The length of described piston shaft 2 can make to push up as described piston a3
During the bottom of described sky cylinder 1, described piston b4 is in outside described sky cylinder 1.
