Abstract
The utility model discloses an air pressure-type pushing injector comprising a needle head 1, a rubber head 2, a piston canister 3, a piston 4, a piston axis 5, and a piston axis handle 6; the utility model is characterized in that: the center of the piston axis 5 and the piston axis handle 6 is arranged with a charge through hole 7 and 7'; a discharge device 8 is arranged on the piston handle 6; one end of the piston canister 3 is arranged with an outer screw thread connected with an internal screw thread of a piston canister cover 9; and seal rings 10 and 11 are arranged inside the piston canister cover 9 for avoiding air leakage. The air pressure-type pushing injector has the advantages of simple structure, convenient operation, reducing the work intensity of the operator, and can easily control the medicine liquid pushing speed to reduce the pain of the patient.
Description
Technical field
This utility model relates to a kind of improvement of syringe, the pusher syringe of specifically a kind of air pressure.
Background technology
Present syringe is made of syringe needle, nipple, piston cylinder, piston, the axis of the piston, piston footstalk, is usually used in Intradermal, subcutaneous, intramuscular and venous injection etc., and injection is that sterile liquid medicine is injected in the body, reaches the whole body curative effect.Intradermal, the general medicinal liquid consumption of injection subcutaneous and intramuscular are little, the injection liquid time is also short, medical personnel operate easily, but during to intravenous injection, general consumption is all bigger, and the medicinal liquid that is used in particular for the intravenous nutrition treatment is bigger, it is long that medical personnel promote the medicinal liquid time, labor intensity of operating staff is big, and speed also is difficult to control on fltting speed, brings misery to patient easily.
Summary of the invention
It is a kind of simple in structure, easy to operate that the purpose of this utility model is to provide, and can alleviate labor intensity of operating staff, and control advances medicinal liquid speed easily again, alleviates the pusher syringe of air pressure of patient's misery.
For reaching above purpose, technical solution adopted in the utility model is: the pusher syringe of this air pressure, constitute by syringe needle, nipple, piston cylinder, piston, the axis of the piston, piston footstalk, it is characterized in that establishing the inflation through hole at the axis of the piston and piston footstalk center, on the piston footstalk, establish aerating device, piston cylinder one end is established external screw thread and is connected with the female thread of piston cover, sets up sealing ring with anti-gas-leak separately in the piston cover.This utility model is also implemented by following measure: described aerating device, constitute by gas tube, inflatable ball, air escape cock, and gas tube one end is communicated with the inflation through hole of piston footstalk, and the other end and inflatable ball are joined, and air escape cock is located on the inflatable ball.When using this utility model, open air escape cock, pulling piston footstalk, in medicinal liquid sucker tube, close air escape cock then, carry out venipuncture, puncture successfully after, take piston cylinder on the other hand, one holds inflatable ball, inflates in piston cylinder continuously, and piston is under the effect of air pressure, push ahead, medicinal liquid is injected in the human vein.
The beneficial effects of the utility model are: compare with present method with manual injection, not only have simple in structurely, easy to operate, can alleviate the advantage of labor intensity of operating staff, advance medicinal liquid speed but also have easy control, alleviate the benefit of patient's misery.
