Abstract
The invention discloses a double-piston injector. The double-piston injector mainly comprises an empty cylinder, a piston shaft, a piston A and a piston B. The empty cylinder is a standard injector empty cylinder, the piston A is located in the empty cylinder, the piston B is located outside the empty cylinder, the piston shaft is provided with a scrapping joint, the two ends of the piston shaft are the same in structure and can be matched with T-shaped holes in the rubber pistons in a tenon mode, the piston A and the piston B are completely identical and located at the two ends of the piston shaft respectively, and the length of the piston shaft can enable the piston B to be located outside the empty cylinder when the piston A is ejected to the bottom of the empty cylinder. A piston handle of a traditional single-piston injector is changed into the rubber pistons so that the double-piston injector can be used in cooperation with an automatic control device, on one hand, the working efficiency is improved, and on the other hand, the labor intensity of medical workers is greatly lowered, and people can enjoy better medical service.
Description
Technical field
The present invention relates to oneSyringe,EspeciallyA kind of double-piston syringe.
Background technology
Along with growth in the living standard, the consciousness that people seek medical advice to hospital is more and more stronger, particularly large hospital, the people beating garter every day is hundreds and thousands of, traditional syringe makes the medical personnel the made up a prescription callus thick owing to the work of high intensity causes having risen on hand, even bleeding blister, not only labor efficiency is substantially reduced, and if things go on like this also the hands of labourer can be caused employment injuries.
Summary of the invention
The technical problem to be solved is to provideA kind of double-piston syringe, change the piston handle of existing tradition single-piston formula syringe into rubber piston so that it is can with automatic controlling equipment with the use of, on the one hand improve work efficiency, greatly reduce the labor intensity of medical personnel on the other hand, make people enjoy better medical services.
This invention address that the technical scheme of its technical problem is:A kind of double-piston syringe, mainly includes sky cylinder, piston shaft, piston A and piston B, and described empty cylinder is standard syringe sky cylinder, and described piston A is in described empty cylinder, and described piston B is outside described empty cylinder.
Described piston shaft is provided with scraps knot, and two-end structure is identical, can both close with the T-shaped 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 empty cylinder, and described piston B is in outside described empty cylinder.
The invention has the beneficial effects as follows, compared with prior art, double-piston syringe by the strength of automatic controlling equipment, can promote work efficiency, reduces labor intensity, people can be allowed to enjoy better medical services, be greatly reinforced again the labor protection to medical personnel.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is inventive piston system structure schematic diagram.
Detailed description of the invention
As it can be seen, a kind of double-piston syringe, mainly including sky cylinder 1, piston shaft 2, piston A3 and piston B4, described empty cylinder 1 is standard syringe sky cylinder, and described piston A3 is in described empty cylinder 1, and described piston B4 is outside described empty cylinder 1.Described piston shaft 2 is provided with scraps knot, and two-end structure is identical, can both close with the T-shaped hole tenon on rubber piston.Described piston A3 is identical with described piston B4, piston shaft 2 two ends described in office.The length of described piston shaft 2 can make when described piston A3 pushes up the bottom of described empty cylinder 1, and it is outside that described piston B4 is in described empty cylinder 1.
