Abstract
The utility model discloses an electric dosage-adjustable automatic needleless injector. The conventional injector completes penetrated injection through the injection needle, so infection easily occurs. The utility model comprises a casing (1); a regulating end cover (2) is connected to the front side of the casing and connected with a regulating stem (4) through a regulating sleeve (3), a striker (5) is arranged in the regulating stem, a regulating ring (6) is connected to the outer side of the regulating stem, the regulating stem is connected with an ampoule bottle (7) in a threaded way, an injection piston (8) is arranged in the ampoule bottle; a transmission mechanism is arranged in the casing and connected with a strike piston (9), the strike piston is connected with a stopper (11) positioned on the casing through a spring (10), the strike piston is positioned on the same axis as the injection piston and the striker. The utility model is used as medical instrument.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of electrodynamic type scalable dosage automatic needleless injection machine.
Background technology:
Traditional syringe all is to adopt injection needle to thrust the formula injection, owing to the in poor shape malpracticees such as infection that cause of the disinfecting of syringe are much, and syringe needle thrusts the formula injection can stay the syringe needle vestige, does not still have the relevant report of needleless injector at present.
Summary of the invention:
The purpose of this utility model is that the problem at above-mentioned existence provides a kind of electrodynamic type scalable dosage automatic needleless injection machine, and that can realize medicinal liquid non-ly thrusts the seamless injection of formula not damaged, the infection of having avoided traditional injection system to cause.
Above-mentioned purpose realizes by following technical scheme:
Electrodynamic type scalable dosage automatic needleless injection machine, its composition comprises: housing, described housing front connects regulates end cap, described adjusting end cap connects adjusting rod by regulating sleeve, described adjusting rod the inside has striker, described adjusting rod connects adjustable ring outward, described adjusting rod is by the ampoule bottle that is threaded, described ampoule bottle the inside has injection ram, drive mechanism is installed in described housing the inside, described drive mechanism connects percussion piston, and described percussion piston connects the plug of deciding that is positioned on the described housing by spring, and described percussion piston and described injection ram and described striker are on same axis.
Described electrodynamic type scalable dosage automatic needleless injection machine, described drive mechanism comprises direct current generator, described direct current generator connects the one-level travelling gear, described one-level travelling gear and the engagement of secondary travelling gear, described secondary travelling gear and involute cylindrical gear engagement, described involute cylindrical gear connects driving rack, and described driving rack connects described percussion piston.
Beneficial effect:
1. this utility model can be realized the non-injection of formula not damaged, the infection and the syringe needle wound of having avoided traditional injection system to cause of thrusting of medicinal liquid.
2. this utility model structural principle is simple and reliable, and is easy to maintenance.
3. this product has been realized the power source of automatic injection by direct current generator and three grades of reducing gear principles.
4. dosage can be regulated by adjusting rod, and the continuous injection of medicinal liquid can be realized by the reset response of spring.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is left views in the accompanying drawing 1.
The specific embodiment:
Embodiment 1:
Electrodynamic type scalable dosage automatic needleless injection machine, its composition comprises: housing 1, described housing front connects regulates end cap 2, described adjusting end cap connects adjusting rod 4 by regulating sleeve 3, described adjusting rod the inside has striker 5, described adjusting rod connects adjustable ring 6 outward, described adjusting rod is by the ampoule bottle 7 that is threaded, described ampoule bottle the inside has injection ram 8, drive mechanism is installed in described housing the inside, described drive mechanism connects percussion piston 9, and described percussion piston connects to be positioned at by spring 10 decides plug 11 on the described housing, and described percussion piston and described injection ram and described striker are on same axis.
Embodiment 2:
Described electrodynamic type scalable dosage automatic needleless injection machine, described drive mechanism comprises direct current generator 12, described direct current generator connects one-level travelling gear 13, described one-level travelling gear and secondary travelling gear engagement 14, roller gear 15 engagements of described secondary travelling gear and the incomplete straight-tooth of involute, the roller gear of the incomplete straight-tooth of described involute connects driving rack 16, and described driving rack connects described percussion piston.
Work process:
Manually suck medicinal liquid for ampoule bottle; Ampoule bottle is screwed in the adjusting rod of syringe; Adjusting rod is screwed in the regulating sleeve; When electrical power, the transmission of motor driven gear group, realize the output high pulling torque by the tertiary gear reducing gear, roller gear pulling tooth bar by the incomplete straight-tooth of involute compresses backward, be about to percussion piston compress energy storage backward, when the incomplete straight spur gear of involute rotates 180 °, break away from engagement with tooth bar, percussion piston is percussion forward fast, the bump striker, the piston that striker then promotes ampoule bottle rapidly is moved to the left, and the minute aperture of medicinal liquid by the ampoule bottle front end in the ampoule bottle penetrated rapidly, and the formation liquid drugs injection, and finish injection process; After injection was finished, spring can spur percussion piston and reset and wait for next time injection process.
Claims (2)
