Description

Launch special syringe

Technical field

The present invention relates to a kind of injector for medical purpose, particularly a kind of syringe that launches at a distance injection that is specifically designed to, belongs to technical field of medical instruments.

Background technology

Syringe is the medicine equipment for sick human or animal being carried out to human body liquid medicine injection, uses injecting method liquid directly can be noted in the blood or body fluid of human body, can make liquid act on rapidly human body or animal, for curing the disease or rescuing the time striven for. But some animals are not understood the object of the mankind to its liquid medicine injection, think people injury it, so people in the time that some animals are carried out to liquid medicine injection, they are desperately struggled, run away, and even people are launched a offensive, and people is in danger. Therefore, the remote injection device of some launching property has also just produced.

General syringe, is all the structure with syringe, syringe needle, piston, push rod, to pull imbibition, the hand-held infusion protocol of thrusting, promote fluid injection. Really the most syringe needle of syringe is to change in history, and modern development is to material abundance, and simply injection tube has also been changed, and has developed into disposable syringe. No matter but be any syringe, all to have to adapt to close in structure hand-held, push-and-pull: syringe rear portion has outstanding non-slipping block, push rod rear portion to have the pushing block opening, all to make ascending pipe with a syringe needle, such structure is not suitable for launching, once leave people's hand support, syringe is will rear portion sagging, even if it is very dark that syringe needle has inserted in human body, but this sagging or fall down or fracture because of the continuous action of animal, and syringe is difficult to inject liquid after the pushing of leaving people. Also there is people that general syringe is slightly done to repacking and launch syringe: linking springs or elastic rubber band on syringe and push rod, in the time launching, unclamp fixed mechanism, be allowed to condition at and launch rear automatic push injection, this can only be also to have certain success rate of launching at a distance injection.

Summary of the invention

Be difficult to general injecting method the shortcoming that some animals are injected in order to overcome general syringe, also launch in order to overcome repacking property the shortcoming that syringe success rate is little, I have invented a kind of special syringe that launches: launch special syringe, it can launch injection to animal at a distance, and ejection target accurately, thrust firm, being difficult to come off, is a kind of syringe that launches injection success rate maximum.

Launching special syringe the taked technical scheme of dealing with problems is: launching special syringe main body is an elongated cylinder that side circumference is smooth, mainly formed by injection tube, syringe needle, piston, push rod, spring, flexible tab, there are two syringe needle running-ons injection tube front portion, can put two syringe needles, injection tube rear portion extends in parallel out two and plays tab, piston connects push rod, the anterior cover of push rod upper spring juxtaposition is in injection tube, piston is withstood in spring front portion, rear portion withstands on the limit balk ring of injection tube, and there is pushing protruding head at push rod rear portion.

Launch special syringe and adopt two needle injection structures, there are two fluid injection outlets its injection tube front portion, namely syringe needle running-on, two syringe needle running-ons do not contact, be placed side by side respectively the circumferential edges of injection tube front portion, distance of separation as far as possible, this is while thrusting animal organism for two syringe needles, two syringe needles can make supporting function better, prevent that the slippage that lets droop of whole syringe from falling. The design of two syringe needles, also can make syringe launch and lunge after animal body, can inject at faster speed liquid, breaks away from syringe in order to avoid risk one's life in the animal short time to struggle.

Launch special syringe and can not carry out push injection by staff, it is to rely on a spring on syringe piston rear portion and push rod to complete push injection, the the same with piston of spring is placed in injection tube, its crown is on piston, hollow part is enclosed within on push rod, that other end withstands on the prominent ring in rear portion of injection tube is upper, and this has just completed it and can promote piston forward and move the setting of injection, and people will overcome this spring and pull push rod and the piston mobile liquid that sucks backward in the time inhaling liquid.

Launching launching of special syringe, to trigger injection be to rely on two flexible tab at injection tube rear portion and the pushing protruding head cooperation at push rod rear portion to complete: before injection, two flexible tab can just be blocked and stop pushing protruding head to be passed through, but in the time that syringe is clashed into suddenly by catapult-launching gear, this just maintaining has been broken, pushing protruding head has been broken through the obstruction of two flexible tab by force owing to being knocked, so push rod and piston have started liquid medicine injection before being pulled to by spring.

The beneficial effect that launches special syringe is: launch special syringe and adopt the design of single injection tube double needle, what not only increase lunges the stability on animal body, also can accelerate the speed of injection; Launch special syringe and adopt the cooperation of spring and elasticity protruding head and push rod, can the impact in the time that utilization is launched trigger and start automatically to advance and inject, be automation and launch at a distance the injecting apparatus of injection success rate maximum.

Detailed description of the invention

Make further implementation below in conjunction with accompanying drawing to launching special injection.

Fig. 1 is the middle cross-section structure schematic diagram that launches special syringe, and this figure has shown and launches all structure members of special syringe and morphological feature. The special syringe that launches in figure is an elongated cylinder, and different from general syringe profile, outer circumference is without any projection, and smooth rule, is suitable for high speed slide in the trajectory of catapult-launching gear, and being also suitable for is to advance in air high speed. It is upper that the front portion of launching special syringe in Fig. 1 has two syringe needles (1) to be enclosed within two syringe needle running-ons (2) of the anterior parallel prong shape of injection tube (3), illustrates that this launches syringe and can change the injection needle of different model. The main body of launching special syringe of Fig. 1 be injection tube (3) with and accessory structure: piston (4), push rod (7), flexible tab (8). In Fig. 1, a spring (5) is enclosed within on the push rod (7) in injection tube (3), a crown is upper at piston (4), and other end withstands on injection tube (3) rear portion limit balk ring (6). The rear portion circumference of injection tube (3) extends back two elasticity protrusion tabs (8), and the protruding head in flexible tab (8) is outstanding a little to the inside, can just stop the passing through of pushing protruding head (9) at push rod (7) rear portion.

Launching special syringe is such use: the hand-held injection tube of user one (3), two fingers of another hand pinch the elastic force that pushing protruding head (9) overcomes spring (5) backward and pull absorption liquid, pushing protruding head (9) pulls back the protruding head place that retreats to flexible tab (8), due to elastic dilatation, only listen " clickly " sound, pushing protruding head (9) is drawn and has been crossed flexible tab (8) by people, people decontrols hand, at this moment flexible tab (8) is rebounded, can work to put in place the temporary transient push rod (7) that hinders by spring (5) top return, at this moment can put in catapult-launching gear and launch launching special syringe, unexpected impact when transmitting can make to push protruding head (9) also impacts suddenly and crosses the obstruction of two flexible tab (8), so piston (4) is moved to sinciput by spring (5), start automatic fluid injection, almost simultaneously, launching special syringe has crossed in the human body that thrusts target animal in the air at high speed, two syringe needles (1) stably hold on syringe, automatically successfully inject very soon complete.
