A kind of animal anesthesia flying needle
Technical field
The invention belongs to Animal Anesthesia apparatus field, particularly to a kind of animal anesthesia flying needle.
Background technology
Syringe is one of the most frequently used medical apparatus and instruments of present medical science, is often used for medical examination and treatment, mainly
Specifically used have, medicine intramuscular injection, and medical intravenous is injected, medicine subcutaneous injection, drawing body fluid etc..Nowadays, the life of syringe
Producing and had sizable scale, according to different clinical needs, the kind of syringe is also varied.
How to give animal injecting drug use, always perplex the thing of veterinary personnel, especially build big, have a violent temper, attack
The wild animal that hitting property is strong.The domestic animal that some wild animal is low with domestication degree, such as Cervus nippon Temminck, it is carried out injection fiber crops
During liquor-saturated medicine, veterinary personnel are difficult to close to injection object.When adopting Cornu Cervi Pantotrichum, it is required for carrying out anesthesia fixing, it is therefore desirable to invention every time
One can be injected at a distance, and simple to operate, the anesthesia flying needle of price material benefit.
The most remote injecting narcotic is to use anaesthetic rifle, and shortcoming is expensive, is also control firearms, common raiser
Use cannot be bought.Some raiser understands self manufacture blowpipe flying needle, needs the gas blown out by mouth to metal tube, by syringe
Blowout is injected.During shortcoming, the dynamics of blowout is inadequate, and distance and direction that syringe flies out are wayward.For existing skill
These problems in art, the present invention provides a kind of animal anesthesia flying needle.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide a kind of animal anesthesia flying needle.
For realizing object above, the technical scheme is that
A kind of animal anesthesia flying needle, including injection device and discharger, injection device includes syringe needle and needle tubing, sets in needle tubing
Having first piston and first connecting rod, the tail end of first connecting rod is positioned at outside needle tubing, is provided with bullet between tail end and the needle tubing of first connecting rod
Property resetting means;Discharger includes launching tube, pressure measuring cylinder, the second piston and second connecting rod, and launching tube internal diameter is less than pressure measuring cylinder
And launching tube is connected with pressure measuring cylinder, the second piston is positioned at pressure measuring cylinder, and second connecting rod one end connects the second piston other end
It is provided with press device.
Described syringe needle includes pin stalk and needle point, and needle point is for sealing structure, and pin stalk side is provided with side opening, and side opening is provided around can
With the slide block along pin stalk slide anteroposterior.
The side opening distance away from needle point is 5-15mm.
Being provided with pintle between described syringe needle and needle tubing, syringe needle is movably fixed on needle tubing by pintle.
Described elasticity reset device is tension spring.
The tail end of described first connecting rod is provided with the balance empennage for balance.
The invention has the beneficial effects as follows:
1, the slide block of present invention syringe needle and a plugging action by being provided with side opening matches, in syringe needle enters animal body
Before, the medicinal liquid in needle tubing will not expose, and after syringe needle enters animal body, slide block is open, and the medicinal liquid in needle tubing passes through side opening
In entrance animal body.
2. novel by arranging elasticity reset device between first connecting rod and needle tubing, make piston have and automatically push away forward
The power of dynamic medicinal liquid, due to the closure of slide block, medicinal liquid can not spill, but when slide block slips away side opening, medicinal liquid can be at elastic reset
Being forced in animal body of device.
3, it is provided with balance empennage at first connecting rod tail end, balance injection device fly out after can be effectively ensured.
4, by launching tube internal diameter less than the pressure measuring cylinder internal diameter of UNICOM, the air pressure in launching tube can be effectively increased, make note
Injection device is launched at faster speed.

Detailed description of the invention
Further illustrate one embodiment of the present invention with reference to the accompanying drawings.
Embodiment 1, with reference to accompanying drawing 1:
A kind of animal anesthesia flying needle, including injection device and discharger, injection device includes syringe needle and needle tubing 5, in needle tubing 5
Being provided with first piston 6 and first connecting rod 7, the tail end of first connecting rod 7 is positioned at outside needle tubing 5, the tail end 9 of first connecting rod and needle tubing 5 it
Between be provided with the tension spring 8 for elastic reset;Discharger includes launching tube 11, pressure measuring cylinder the 12, second piston 13 and second
Connecting rod 14, launching tube 11 internal diameter is connected with pressure measuring cylinder 13 less than pressure measuring cylinder 12 and launching tube 11, and the second piston 13 is positioned at pressure
In power cylinder 12, second connecting rod 14 one end connects second piston 13 other end and is provided with press device 15.The internal diameter of launching tube 11 and pin
Within equal or launching tube 11 the internal diameter 0.5mm bigger than the external diameter of needle tubing 5 of the external diameter of pipe 5.
Syringe needle includes pin stalk 2 and needle point 1, and needle point 1 is for sealing structure, and pin obstructs 2 sides and is provided with side opening 3, and side opening 3 is provided around
The slide block 16 of 2 slide anteroposterior can be obstructed along pin.
The side opening 3 distance away from needle point 1 is 5-15mm.
Being provided with pintle 4 between described syringe needle and needle tubing 5, syringe needle is movably fixed on needle tubing 5 by pintle 4.
