In use, when laboratory animal peace and quiet, directly this animal injection device being invested laboratory animal, entry needle injects
The muscular tissue of animal, compresses and holds air bag, and compressed air is in flexible pipe enters air chamber, and the pressure of air chamber increases, and promotes
Piston is moved to the left, and the liquid drug in drug injection district, in entry needle is expelled to the muscular tissue of animal, treats drug injection
After completing, extract entry needle, unclamp and hold air bag, piston reset.During this this animal injection device is thrown, if soft
The length long enough of pipe, entry needle would not come off, in injection process because of animal innervate, it is ensured that medicine is noted completely
Being mapped in animal body, injection process will not be interrupted, and has good stability;Hold air bag, simple in construction, insert at entry needle
After entering animal muscle tissue, air bag is held in compression, it is possible to by drug injection to animal body, without operation push rod, tool
There is feature easy to use;The present invention uses the method for throwing, injected by injection device in animal body, it is to avoid research worker with
The contact of animal, security performance is preferable, also eliminates fixture and the clamping operation to animal, has that cost is relatively low and work efficiency
Higher feature.
As preferably, the left end of described syringe is provided with the balancing weight being connected with entry needle.Balancing weight, simple in construction, increase
Add the weight of this injection device, during this injection device is thrown, add inertia force, it is ensured that entry needle can puncture
The skin histology of animal, injects the muscular tissue of animal, improves the disposable success rate thrown, improves work efficiency further.
As preferably, described balancing weight is threadeded with syringe.This structure has the convenient feature of installation and removal, real
Now this animal injection device can repeatedly Reusability, reduce cost further.
As preferably, described animal injection device also includes the needle holder suitable with entry needle, described needle holder with
Balancing weight is threaded.Needle holder, increases the weight of this injection device further, adds inertia force, improves disposable throwing
Success rate;Meanwhile, needle holder and the screw connection structure of balancing weight so that needle holder is convenient with balancing weight installation and removal.
As preferably, in the air chamber of described syringe, it is provided with the fairlead suitable with push rod.Fairlead, structure letter
Single, push rod is had guide effect, it is ensured that the stability of injection process.
As preferably, described fairlead is structure as a whole with syringe.This structure eliminates the installation procedure of fairlead, enters
One step reduces cost.
As preferably, in described air chamber, be provided with the elastic bag being connected with flexible pipe, the left end of described elastic bag with
Push rod is connected, and the right-hand member of elastic bag is connected with shrouding.Elastic bag, simple in construction, can be extension airbag or general soft
Property air bag, extension airbag can increase the guide effect to push rod, improves the stability of injection process;Flexible air-bag, can be by
Step is crowded with spaces of air chamber, and the injection speed of entry needle is more slow, and the stimulation to animal is less, and the accuracy of experiment is preferable.
As preferably, described flexible pipe is provided with stop valve.After medicine disposable inject, closedown stop valve, can
To prevent entry needle pumpback medicine or the blood of animal, the accuracy of experiment is preferable.
Owing to taking above-mentioned technical scheme, a kind of animal injection device that the present invention provides has such useful effect
