A kind of animal anesthesia flying needle
Technical field
The invention belongs to Animal Anesthesia apparatus field, more particularly to a kind of animal anesthesia flying needle.
Background technology
Syringe is one of the most frequently used medicine equipment of present medical science, is often used for medical examination and treatment, mainly
It is specifically used to have, medicine intramuscular injection, medical intravenous injection, medicine hypodermic injection, drawing body fluid etc..Nowadays, the life of syringe
Production has sizable scale, and according to different clinical needs, the species of syringe is also varied.
How animal injecting drug use is given, be always the thing for perplexing animal doctor personnel, especially build is big, has a violent temper, and attacks
The strong wild animal of hitting property.Some wild animals domestic animal low with domestication degree, such as sika deer, injection fiber crops are carried out to it
During liquor-saturated medicine, animal doctor personnel are difficult close to injection object.When adopting pilose antler every time, it is required for carrying out anesthesia fixation, it is therefore desirable to invent
One kind can inject at a distance, and simple to operate, the anesthesia flying needle of price material benefit.
Remote injecting narcotic is to use anaesthetic rifle at present, and shortcoming is expensive, and control firearms, common raiser
Use can not be bought.Some raisers understand self manufacture blowpipe flying needle, it is necessary to the gas blown out by mouth to metal tube, by syringe
Blowout is injected.During shortcoming, the dynamics of blowout is inadequate, and the distance and direction that syringe flies out are difficult to control.For existing skill
These problems in art, the present invention provide a kind of animal anesthesia flying needle.
The content 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.
To realize object above, the technical scheme is that:
A kind of animal includes syringe needle and needle tubing, needle tubing with anesthesia flying needle, including injection device and emitter, injection device
Interior to be provided with first piston and first connecting rod, the tail end of first connecting rod is located at outside needle tubing, set between the tail end and needle tubing of first connecting rod
Flexible resetting means;Emitter includes launching tube, pressure measuring cylinder, second piston and second connecting rod, and launching tube internal diameter is less than pressure
Power cylinder and launching tube is connected with pressure measuring cylinder, second piston is located in pressure measuring cylinder, and second connecting rod one end connection second piston is another
One end is provided with press device.
The syringe needle includes pin stalk and needle point, and needle point is sealing structure, and pin stalk side is provided with side opening, and being provided with around side opening can
With the sliding block slid back and forth along pin stalk.
Distance of the side opening away from needle point is 5-15mm.
Pintle is provided between the syringe needle and needle tubing, syringe needle is movably fixed on needle tubing by pintle.
The elasticity reset device is tension spring.
The tail end of the first connecting rod is provided with the balance empennage for balancing.
The beneficial effects of the invention are as follows:
1st, the present invention is engaged by the syringe needle for being provided with side opening and the sliding block for playing plugging action, enters animal in syringe needle
Before in vivo, the decoction in needle tubing will not expose, and after syringe needle enters animal body, sliding block is open, and the decoction in needle tubing passes through
Side opening enters in animal body.
2. it is new by setting elasticity reset device between first connecting rod and needle tubing, there is piston and push away forward automatically
The power of dynamic decoction, due to the closure of sliding block, decoction can not spill, but when sliding block slips away side opening, decoction can be in elastic reset
Device is forced into animal body.
3rd, balance empennage is provided with first connecting rod tail end, the balance after injection device flies out can be effectively ensured.
4th, it is less than the pressure measuring cylinder internal diameter of UNICOM by launching tube internal diameter, the air pressure that can be effectively increased in launching tube, makes note
Injection device is launched at faster speed.
