Abstract

The utility model relates to a remote automatic injector, comprising a needle head, a needle cylinder and a piston. The needle head and the needle cylinder are movably connected by a movable tube which is provided with a leakage hole and a rubber sealing ring. One end of the movable tube opening is blocked by a rubber plug. The needle cylinder is formed by the threaded connection of a needle cylinder body to a compression resistant cylinder provided with a tail and an axis clamping hole. A piston is arranged at the inner cavity of the needle cylinder. The rubber sealing ring, a bayonet piston shaft and a spring are arranged on the piston. The injector is transmitted by a transmitting apparatus. The utility model is suitable for the immunization inoculation of wild animals and furious livestock, field emergency and stopping violent events. The utility model has the advantages of simple structure, easy use, automatic injection to an object at a long distance.

Description

Far distance automatic syringe

This utility model belongs to a kind of injector for medical purpose, especially for wild animal, and violent domestic animal immunization inocultation, a kind of far distance automatic syringe of field emergency and prevention incident of violence.

At present the syringe that uses is made up of syringe needle, syringe, piston etc., uses easy to carryly, and weak point is closely bimanualness.For wild animal, violent domestic animal immunization inocultation and remote field emergency prevent incident of violence to be severely limited.

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and a kind of improved simple in structure, easy to use is provided, injector for medical purpose that can far distance automatic injection.

Solution of the present utility model is: the movable connection between syringe needle and the syringe, syringe needle is contained in and is provided with liquid-leaking nozzle, adjustable pipe one end of rubber sealing ring, the other end of adjustable pipe is inserted in the syringe papillary foramina to the syringe inner chamber, the movable mouth of pipe stops up with rubber closure, syringe is threaded with the resistance to compression tube by needle cylinder main body and forms, establish a shell fragment overhead kick on the syringe nipple, on the resistance to compression tube empennage is housed, resistance to compression tube top has a hole clipping, piston is loaded on the syringe inner chamber, is embedded with rubber sealing ring, buckle the axis of the piston on the piston, and spring housing is on the buckle the axis of the piston.

Fig. 1 is far distance automatic syringe construction figure

Describe one of the present utility model in detail below in conjunction with accompanying drawing and execute example

The far distance automatic syringe of describing among Fig. 1, be movable the connection between syringe needle and the syringe, metal needle (1) is contained in and is provided with liquid-leaking nozzle (3), one end of the non-toxic transparent plastic of rubber sealing ring (4) or glass adjustable pipe (2), the other end of adjustable pipe (2) is inserted in syringe nipple (7) endoporus to the syringe inner chamber, the movable mouth of pipe stops up with rubber closure (5), adjustable pipe (2) can move forward and backward in syringe nipple (7) endoporus, glass or non-toxic transparent plastic syringe (8) are threaded with non-toxic transparent plastic resistance to compression tube (9) by needle cylinder main body and form, syringe nipple (7) is provided with shell fragment overhead kick (6), adorn one chevron shaped on the resistance to compression tube (9), cross, rectangle or pyramid type empennage (10), resistance to compression tube top has a hole clipping (11), syringe (8) inner chamber has glass or non-toxic transparent plastic piston (12), rubber sealing ring (13) is housed on the piston (12), adorn a metal buckle the axis of the piston (14) in its centre bore, spring (15) is enclosed within on the buckle the axis of the piston (14), one end withstands piston (12), one end withstands resistance to compression tube top, and bayonet socket the axis of the piston (14) passes spring (15), axle hole clipping (11) is stretched out empennage (10).

During powder charge, syringe needle (1) is thrust ampoule, syringe needle (1) is obstructed and stretches into syringe (8) inner chamber to move after the counteracting force promotion adjustable pipe (2), expose liquid-leaking nozzle (3), spur bayonet socket the axis of the piston (14) again, piston moves after (12), syringe (8) inner chamber forms negative-pressure vacuum, medicinal liquid is then by syringe needle (1), adjustable pipe (2), liquid-leaking nozzle (3) sucks syringe (8) inner chamber, tight syringe needle chimb is colluded in shell fragment overhead kick simultaneously (6), control adjustable pipe (2) moves and to reset, after medicinal liquid sucks, with syringe (8) emptying gas up, unclamp shell fragment overhead kick (6) and buckle the axis of the piston (14), because the pressure of spring (15) promotion piston (12) extruding medicinal liquid makes rubber closure (5) stop up adjustable pipe (2) and resets, the bayonet socket with bayonet socket the axis of the piston (14) snaps in a hole clipping (12) again, has just formed no press seal and has closed ampoule.

During use, buckle the axis of the piston (14) is extracted out from syringe (8) piston (12), spring (15) promotes piston (12) extruding medicinal liquid, makes medicinal liquid be pressured state, and after discharger was launched this syringe, empennage (10) was controlled its directed flight; When syringe needle 1 thrusts object, because promoting adjustable pipe (2), behind syringe 8 inner chambers, moves counteracting force, expose liquid-leaking nozzle (3), tight syringe needle (1) chimb is colluded in shell fragment overhead kick simultaneously (6), control adjustable pipe (2) resets, under the elastic force effect of spring (15), medicinal liquid then injects object by liquid-leaking nozzle (3), adjustable pipe (2), syringe needle (1), realizes the purpose of far distance automatic injection.

Claims

1, a kind of far distance automatic syringe, comprise syringe needle, syringe, piston, it is characterized in that being between syringe needle and the syringe movable the connection, syringe needle (1) is contained in and is provided with liquid-leaking nozzle (3), adjustable pipe (2) one ends of rubber sealing ring (4), the other end of adjustable pipe (2) is inserted in syringe nipple (7) endoporus to the syringe inner chamber, the movable mouth of pipe stops up with rubber closure (5), syringe nipple (7) is provided with shell fragment overhead kick (6), syringe (8) is threaded with resistance to compression tube (9) by needle cylinder main body, empennage (10) is housed on the resistance to compression tube (9), its top has a hole clipping (11), and syringe (8) inner chamber is equipped with piston (12), is embedded with rubber sealing ring (13) on the piston (12), adorn a buckle the axis of the piston (14) in its centre bore, be inserted in spring (15) on the buckle the axis of the piston (14).
