Abstract

The utility model relates to an electric needleless injector, in particular to an injection tool, which belongs to a medical treatment apparatus. The injector comprises an ampoule bottle (1), an ampoule bottle sleeve (2), an injection rod (3), a connector (4), a switch (5), an impinging disk (6), a spring (7), an adjusting rod (8), a guiding pad (9), a tail cap (11), a pulling line (12), a spring sleeve (13), an adjusting tube (14), an iron core (16) and an electromagnet (17). The electromagnet (17) is connected with a power supply through the switch (5), the front end of the pulling line (12) is fixed on the iron core (16), the tail end thereof penetrates through the tail cap (11) and the guiding pad (9), and the spring (7) arranged between the impinging disk (6) and the guiding pad (9) is fixed on the impinging disk (6). An adjusting tube inner thread (15) matched with the upper end of the adjusting rod (8) and installed on the guiding pad (9) in a sliding way is arranged on the inner wall of the adjusting tube (14), and a slide path (10) matched with the adjusting rod (8) in a sliding way is arranged on the spring sleeve (13). Compared with the prior high pressure needleless and painless injector, the injection tool provided by the utility model has the advantages that the injection tool can be injected continuously, and the operation is easy and convenient.

Description

Electric needleless injectors

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly a kind of injection tool.

The background skill is asked

Existing " high pressure needleless painless syringe " is modern more advanced a kind of subcutaneous injection instrument.It has needle injection to have painless, safety and does not have advantages such as infection than traditional.Must earlier its be installed in " box resets " lining of special use during use, move the compression spring then by hand, the impulsive force of utilizing retracting spring to produce is injected the medicinal liquid in the ampoule bottle subcutaneous.If will continue injection, then must replace ampoule bottle, compress spring again; Spring of every compression can only be injected once.Obviously, use that this syringe is time-consuming, effort, complex operation and can not continuous operation.

Summary of the invention

This utility model is the defective at existing " high pressure needleless, painless syringe ", and a kind of continuous operation function that has is provided, and with driven by power, electric needleless injectors easy and simple to handle.

The technical scheme in the invention for solving the technical problem is: this syringe contains ampoule bottle, ampoule bottle sleeve pipe, injection rod, joint, switch, bump cake, spring, adjusting rod, leads pad, tail medicated cap, backguy, pogo barrel, adjustable pipe, iron core, electric magnet and electromagnetism box.The electric magnet of device in the electromagnetism box is electrically connected by switch and the power supply that is installed on the joint, and ampoule bottle is connected with the ampoule bottle casing threads, and the ampoule bottle sleeve pipe is connected with joint screw thread, and tail medicated cap and pogo barrel are threaded, and iron core and electric magnet are slidingly matched.

The head end of backguy is fixed on the iron core, and end passes the tail medicated cap, lead pad and device at bump cake and the spring of leading between the pad, is fixed on and clashes on the cake.

For continuous injection, establish and be installed in the adjustable pipe female thread that is slidingly matched on the adjusting rod of leading on the pad at the adjustable pipe inwall, on pogo barrel, establish the slideway that is slidingly matched with adjusting rod.

The beneficial effects of the utility model are, use driven by power, can continuous operation, and injection volume can be regulated and control arbitrarily, and is easy and simple to handle, time saving and energy saving.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

This accompanying drawing is the longitudinal sectional drawing of electric needleless injectors.

Among the figure, 1. ampoule bottle, 2. the ampoule bottle sleeve pipe, 3. injection rod, 4. joint, 5. switch, 6. the bump cake, 7. spring, 8. adjusting rod, 9. lead pad, 10. slideway, 11. tail medicated caps, 12. backguys, 13. pogo barrels, i4. adjustable pipe, 15. adjustable pipe female threads, 16. iron cores, 17. electric magnet, 18. electromagnetism boxes.

The specific embodiment

Device is electrically connected by switch 5 and the power supply that is installed on the joint 4 at the electric magnet 17 of 18 li in electromagnetism box, ampoule bottle 1 and ampoule bottle sleeve pipe 2 are threaded, ampoule bottle sleeve pipe 2 and joint 4 are threaded, tail medicated cap 11 and and pogo barrel 13 be threaded, iron core 16 and electric magnet 17 are slidingly matched.

The head end of backguy 12 is fixed on the iron core 16, end passes tail medicated cap 11, lead pad 9 and device bump cake 6 with lead spring 7 between the pad 9 and be fixed on and clash on the cake 6.

In order to inject continuously, establish and be installed at adjustable pipe 14 inwalls and lead the adjustable pipe female thread 15 that adjusting rod 8 upper ends on the pad 9 are slidingly matched, on pogo barrel 13, establish the slideway 10. that is slidingly matched with adjusting rod 8
