The present invention relates to a kind of injector for medical purpose, be particularly a kind ofly specifically designed to the syringe launching injection at a distance, belong to technical field of medical instruments.
Background technology
Syringe is the medical apparatus and instruments for carrying out human body liquid medicine injection to sick human or animal, uses injecting method medicinal liquid directly can be noted in the blood or body fluid of human body, medicinal liquid can be made to act on human body or animal rapidly, for curing the disease or rescuing the time striven for.But some animals do not understand the object of the mankind to its liquid medicine injection, think that people are injuring it, so people are when carrying out liquid medicine injection to some animals, they are desperately struggled, run away, even people is launched a offensive, people is in danger.Therefore, the remote injection device of some launching property also just creates.
General syringe is all with the structure of syringe, syringe needle, piston, push rod, to pull imbibition, the hand-held infusion protocol of thrusting, promoting fluid injection.Really the most syringe needle of syringe to change in history, and modern development is sufficient to material, and simply injection tube has also been changed, and has developed into disposable syringe.No matter but be any syringe, all have to adapt to close in structure that is hand-held, push-and-pull: there is outstanding non-slipping block at syringe rear portion, there is the pushing block opened at push rod rear portion, all make ascending pipe with a syringe needle, such structure is not suitable for launching, once leave the hands support of people, syringe will rear portion sagging, even if syringe needle has inserted in human body very dark, but this sagging or fall down because of the continuous action of animal or fracture, and syringe is difficult to carry out injection medicinal liquid after the pushing leaving people.Also there is people that general syringe is slightly done repacking and launch syringe: linking springs or elastic rubber band on syringe and push rod, fixed mechanism is unclamped when launching, be allowed to condition at and launch rear automatic push injection, this also can only be have certain success rate of launching injection at a distance.
Summary of the invention
In order to overcome the shortcoming that general syringe and general injecting method are difficult to inject some animals, also the little shortcoming of syringe success rate is launched in order to overcome repacking property, my invention is a kind of special launches syringe: 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 ofly launch the maximum syringe of injection success rate.
Launching special syringe taked technical scheme of dealing with problems is: launching special syringe main body is the elongated cylinder that a side surface circumference is smooth, form primarily of injection tube, syringe needle, piston, push rod, spring, flexible tab, there are two syringe needle running-ons injection tube front portion, two syringe needles can be put, injection tube rear portion extends in parallel out two pieces and plays tab, piston connects push rod, push rod front portion puts spring and is placed 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 the circumferential edges of injection tube front portion respectively, as far as possible distance of separation, this be in order to two syringe needles thrust animal organism time, two syringe needles can make supporting function better, prevent the slippage that lets droop of whole syringe from falling.The design of two syringe needles, after syringe also being made to launch lunge animal body, can inject medicinal liquid at faster speed, in order to avoid syringe is broken away from struggle of risking one's life in the animal short time.
Launch special syringe and can not carry out push injection by staff, it relies 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 push rod, the rear portion that other end withstands on injection tube is dashed forward on ring, this completes it and can promote the setting that piston moves forward injection, and people will overcome this spring and carry out pulling push rod and piston mobile suction medicinal liquid backward when inhaling medicinal liquid.
The trigger injection that launches launching special syringe relies on two pieces of flexible tab at injection tube rear portion and the pushing protruding head cooperation at push rod rear portion to complete: before the injection, two pieces of flexible tab can just be blocked and stop pushing protruding head to be passed through, but when syringe is clashed into suddenly by catapult-launching gear, this maintenance has just been broken, pushing protruding head has broken through the obstruction of two pieces of flexible tab by force owing to being knocked, so push rod and piston start liquid medicine injection before being pulled to by spring.
The beneficial effect launching special syringe is: launch the design that special syringe adopts single injection tube double needle, the stability lunged on animal body not only increased, also can accelerate the speed of injection; Launch the cooperation that special syringe adopts spring and elasticity protruding head and push rod, automatically can advance injection utilizing impact force when launching to carry out triggerings beginning, be automatization and launch the maximum injecting apparatus of injection success rate at a distance.
