Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a veterinary injection machine, and more particularly to a veterinary injection machine suitable for continuous vaccination such as vaccination of day-old chicks.

[Conventional technology]

Conventionally, such veterinary injection machines have been put into practical use, including fixed types that inject by pressing against the animal, and movable types that inject by moving the syringe.

[Problem that the invention attempts to solve]

However, the fixed type lacks ease of handling, and the conventional movable type requires a person to push the piston with hand power to inject, so in the case of continuous vaccination, the physical fatigue of the worker is high. It was equally painful. Moreover, since the pressing operation is performed intuitively by humans, it is often impossible to maintain the same injection amount.

Therefore, the inventor of the present invention has conducted various studies in order to eliminate such drawbacks of the conventional methods, and has devised the so-called piston-type veterinary injection machine of the present invention, which can perform inoculation operations extremely easily by using compressed air. It is something.

[Means for solving problems]

That is, the present invention has an air valve inside that is equipped with an air pipe for connecting to an external compressed air source and an air pipe connected to a double-sided operating air cylinder body described later, and has a push lever on the outside that operates the air valve. a gripping body; a syringe body horizontally disposed in a substantially T-shape on the upper part of the gripping body and having separate drug suction ports and discharge ports; and a syringe body disposed in parallel with the upper part of the syringe body and having the air valve This is a veterinary injection machine consisting of a double-sided actuated air cylinder body that advances and retreats the piston portion of the syringe body in conjunction with the operation of the syringe body.

〔Example〕

The present invention will be further explained below with reference to drawings showing embodiments.

Reference numeral A denotes a gripping body, which is shaped like a so-called piston gripping portion. Reference numeral 1 denotes a 5-port air valve installed inside the grip body, and an air pipe 2 for connecting an external compressed air source (not shown) is attached to the air inlet at the bottom, and the other end is connected to the grip body. The air pipes 3, 3 are made to protrude outside of A, and air pipes 3,
4, and connect the other ends to the left and right air inlet ports 3 of the both-side operating air cylinder body C, which will be described later.
1 and 41.

Reference numeral 5 denotes a press lever for pressing the operating button 6 of the air valve 1 protruding from the outside of the grip body A, and is attached to the outside of the grip body A like the trigger of a pistol.

B is a syringe body, which is placed horizontally on the upper part of the gripping body A in a substantially T-shape. This syringe body B
The syringe is composed of a syringe barrel part 7 and a piston part 8 like a conventional movable syringe, but unlike the conventional one, the syringe barrel part 7 not only has a drug solution outlet 9 at the tip but also has a drug solution suction port on its lower side. The mouth 10 is specially shaped. Note that these discharge ports 9 and suction ports 10
The simultaneous opening of both is prevented by appropriate valve mechanisms 11 and 12.

C is a double-sided actuated air cylinder body, which is installed above the syringe body B in parallel with the syringe body B. The stroke shaft 13 of the air cylinder body C and the above-mentioned syringe body piston part 8 are synchronously connected by a connecting rod 14, and together with the connection with the air valve 1 through the above-mentioned air pipes 3 and 4, the air In conjunction with the actuation of the valve 1, the stroke axis 13 also moves the syringe body piston part 8.
is forced to advance and retreat.

Incidentally, if a bolt shaft 15 is appropriately arranged in parallel between the stroke shaft 13 and the piston part 8, and is inserted through the connecting rod 14, a stopper 17 that can be screwed together with an external knob 16 is provided at the end thereof. This is especially advantageous because the stroke of the piston portion 8 can be freely adjusted, and the injection amount can be freely selected depending on the medicinal solution.

[Effect]

As the present invention is constructed as described above, in order to use it, first attach a syringe needle to the drug outlet 9, connect the end of the air pipe 2 to an external compressed air cylinder, and connect the hose as appropriate. The drug solution suction port 10 is connected to the drug solution bottle via the drug solution suction port 10. In this state, if the press lever 5 is pulled like a pistol trigger, the actuation button 6 is pressed and the air valve 1 is actuated.
Compressed air passes through the air pipes 2 and 3 to the left air inlet portion 31 of the air cylinder body C that operates on both sides.
, and the stroke axis 13 moves rightward in the figure. Along with this movement, the piston part 8 also moves to the right in the figure, and the inside of the syringe barrel part 7 becomes negative pressure.
A drug solution is introduced into the syringe barrel portion 7 through the drug solution suction port 10 . Next, once the pressure lever 5 is released and the injection needle is inserted into the animal, when the pressure lever is pulled again, the air valve 1 is operated again, and the compressed air is now passed through the air pipes 2 and 4 to the air cylinder. The air is introduced into the right air introduction port 41 of the body C, and the stroke axis 13 moves to the left in the figure. Along with this movement, the piston part 8 also moves to the left in the figure,
Since the medicinal liquid in the syringe barrel portion 7 is pressed, the medicinal liquid is injected into the animal's body using the injection needle attached to the medicinal liquid outlet 9, similar to a normal syringe. From now on, you can repeat this operation.

[Effect of idea]

Therefore, using the present invention, injections can be performed by simply pulling the pressure lever like the trigger of a pistol, and the ease of operation is extremely remarkable. This allows for extremely efficient inoculation work without feeling fatigued.

Furthermore, since the injection in the present invention is carried out by the uniform stroke of the piston using compressed air, an accurate injection amount can be reliably maintained during the operation.
