Abstract

PROBLEM TO BE SOLVED: To achieve an injection instantaneously into animals such as porker at a standing attitude by mounting an injector on the tip side of a bar-shaped body to interlock for pressing a plunger of the injector by a handle provided on the body as freely relatively movable forward or backward therefrom. SOLUTION: A paint impregnated part 10 is pressed onto the body surface of animal by holding a handle 1 with a hand and a slider 22 is retracted against a spring 21 so that the paint impregnated part 10 is pressed onto the body surface under a spring force to be applied. At the same time, the needle 23 of an injector 3 is stuck into the body of the animal. But, as further retraction of the slider 22 is regulated, the tip 2a of a bar-shaped body 2 contacts the body surface of the animal to prevent furthering of the injector needle 23. Under such a condition, by the further pressing of the handle 1, the handle 1 advances to the body 2 against a spring 4 to push forward the plunger through a link shaft 5, forcing a medical fluid in the injector 3 to be injected into the body of the animal.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for injecting a medicinal solution into an animal such as a moving pork.

[0002]

2. Description of the Related Art In a pig farm where a large number of pigs of 1,000 or more are bred, there is no sickness or a weak pig, and it is checked once or twice a day and an injection is made if necessary. Work is essential. In this case, for the sake of work efficiency, it is necessary to instantly inject the moving pig without catching it and fixing it.

[0003] In a large-scale pig farm, in order to distinguish an injected pig from other pigs, it is also necessary to perform a coloring operation by spraying after the injection. Therefore, an injection and a spray operation are alternately performed by holding a syringe and a spray tube containing paint.

[0004]

As described above, the work of injecting or spraying a large number of pigs of several tens to several hundreds or more is carried out while leaning forward, which is unnatural. As I work in a posture, not only is it easy to get tired, but it also causes pain in my arms and back pain.

Injected pigs may be surprised and run away and may not be able to be distinguished from other pigs. Therefore, immediately after the injection, it is necessary to spray immediately, and swift action is required, resulting in overwork. Sometimes.

A technical object of the present invention is to pay attention to such a problem, and to make it possible to easily perform injection and application of coating material while standing upright.

BEST MODE FOR CARRYING OUT THE INVENTION Next, it will be described how the injection device for animals according to the present invention is practically embodied. FIG.
3 to 3 show an embodiment of an injection device for animals according to the present invention, wherein FIG. 1 is a perspective view, FIG. 2 is a side view, and FIG. 3 is a syringe 3.
It is a perspective view of the state where the use of the drug solution inside was completed.

Reference numeral 2 is a bar-shaped main body, and in the illustrated example, a synthetic resin cylinder is used. In this bar-shaped body 2,
The handle 1 is attached so as to be relatively slidable in the longitudinal direction of the bar-shaped body 2, and the syringe 3 is attached to the tip 2a side of the bar-shaped body 2.

The plunger for pushing out the liquid medicine inside the syringe 3 is connected to the tension spring 4 through the connecting shaft 5 and the screw rod 6, and the other end of the tension spring 4 is connected to the rear end of the bar-shaped body 2. It is installed. The connecting shaft 5 passes through the handle 1, and a nut-shaped contact member 19 is fixed to the connecting shaft 5 so as to abut the front surface of the handle 1.

On the other hand, a paint impregnating portion 10 is provided on the tip end side of the bar-shaped main body 2 so as to retreat against the elasticity. That is, as shown in FIG. 2, the compression coil spring 21 is built in the tubular portion 20 fixed to the bar-shaped main body 2, and the rear end of the slider 22 is inserted thereon. This slider 22 is detachable, and has a tip at which the paint impregnation part 1
0, and the paint is incorporated inside.

That is, when the paint impregnating portion 10 made of sponge or the like is removed, the paint is put into the cylindrical slider 22, and then the paint impregnating portion 10 is fitted, the paint impregnating portion 10 is inserted.
Is always impregnated with paint. When not in use, a cap for preventing evaporation and drying is put on the paint impregnated portion 10. A structure is also possible in which paint is put in from the rear end of the slider 22 and closed with a cap.

Now, when the handle 1 is held by hand and the paint impregnated portion 10 is pressed against the body surface of the animal, the slider 22 resists the spring force of the compression coil spring 21 and is guided by the semi-cylindrical guide 24. The paint impregnated portion 10 is pressed against the body surface by the spring force at this time, and the paint is applied.

At the same time, the injection needle 23 at the tip of the syringe 3 pierces the body of the animal, but the slider 22 cannot be further retracted, and the tip 2a of the bar-shaped body 2 hits the body surface of the animal. 23 cannot enter any more. Therefore, when the handle 1 is pushed further, the handle 1 moves forward against the bar-shaped body 2 against the spring 4, and the contact member 19
Push forward to advance the plunger through the connecting shaft 5.

As a result, the drug solution in the injector 3 is pushed out into the body of the animal and injection is performed. FIG. 3 shows a state in which the plunger has been advanced and all the liquid medicine has been pushed out in this manner.

When the injection needle sticks, the animal usually escapes more surprisingly, so the injection needle 23 comes out of the animal's body after the injection, but even if it is not, the handle 1 does not move any further. Then, when the handle 1 is sensed, when the handle 1 is pulled, the injection needle 23 comes off the body of the animal, the injection work is completed, and the paint application work is completed as described above.

The spring force of the compression coil spring 21 causes the slider 22 to move forward, and the paint impregnated portion 10 is stopped in a state of slightly protruding from the tip 2a of the bar-shaped body 2 to prepare for the next work.

When the drug solution in the syringe 3 is injected once, the above-mentioned structure is sufficient, but in practice, the drug solution in the syringe 3 is often injected, for example, in 5 or 10 divided doses. Therefore, the nut 7 is screwed onto the threaded rod 6, and the stopper 8 is fixed to the bar-shaped body 2 at the position where the front surface of the nut 7 abuts.

Further, as shown in FIG. 4, the bar-shaped main body 2 is provided with a lock means 9 which allows only the forward movement of the screw rod 6. That is, the "L" shaped metal fitting 9 composed of the inclined portion 9a, the screw rod 6 and the shaft portion 9b in the direction orthogonal to the bar portion is built in the bar-shaped main body 2, and the upper end of the inclined portion 9a is supported by the support shaft 9c. It is rotatably supported by 2, and the shaft portion 9b penetrates through the compression coil spring 9s and is supported on the back surface of the bar-shaped main body 2.

The tip 9d of the L-shaped metal fitting is fitted into the thread of the screw rod 6 by the spring force of the coil spring 9s. Since the screw rod 6 is pulled rearward by the tension coil spring 4, the screw thread is caught on the tip 9d of the L-shaped metal fitting 9 and cannot be retracted as shown in the figure, but the screw thread resists the spring force of the coil spring 9s. Then, the letter-shaped metal fitting 9 can be pushed away to move forward.

Now, if the capacity of the syringe 3 is, for example, 10 cc, in order to inject the entire 10 cc, it is assumed that the screw rod 6 is advanced by 10 threads of the screw rod 6 and the plunger is advanced to the end. , Divided into 2 cc, for example, 5
To make multiple injections, screw thread 6 2 screw threads each
It is necessary to move forward.

To this end, as shown in FIG. 1, when the plunger 3 is retracted and the syringe 3 is filled with the drug solution, and the nut 7 is in contact with the stopper 8, the nut 7 is turned by hand to rotate the screw rod 6 Figure 2
As described above, a space S is provided between the stopper 8 and two peaks.

In this state, when the handle 1 is held in the hand and the injection needle is pierced into the body surface of the animal in the above-described manner, and the handle 1 is further pushed toward the animal side, the connecting shaft 5 and the screw are pushed through the contact member 19. The rod 6 is also advanced, the plunger of the syringe 3 is pushed, and the injection solution is pushed out from the needle.

At this time, until the nut 7 hits the stopper 8, the screw rod 6 pushes away the lock fitting 9 and advances together with the connecting shaft 5 and the plunger, so that the chemical liquid of the interval S is pushed out and 2 cc of the chemical liquid is discharged. Be injected.

Next, the nut 7 is again rotated by two peaks to be retracted so that a space S is formed between the nut 7 and the stopper 8, and then the handle 1 is pushed to inject. By repeating such an operation, injection can be performed 5 times by 2 cc each.

After the injection of 5 times, the drug solution in the syringe 3 is used up, and the screw rod 6 is also moved to the end as shown in FIG. 3, so the plunger is retracted and the drug solution in the syringe 3 is moved. Need to be filled.

In this operation, first, the operating lever 9h of the locking means 9 is pushed up with a finger to remove the L-shaped metal fitting 9 from the threaded rod 6, and the tension coil spring 4 causes the threaded rod 6, the connecting shaft 5 and the plunger. Moves backward, and at this time, the liquid medicine is inhaled into the syringe 3. Further, the handle 1 also retracts with respect to the bar-shaped main body 2.

Since the syringe 3 is detachable with respect to the syringe holder 25 fixed to the bar-shaped main body 2,
The amount of injection per operation and the number of injections can be freely selected by exchanging with a syringe having a different capacity or changing the interval S depending on the rotation amount of the nut 7.

As described above, when the paint impregnating portion 10 hits the body surface of a pig or the like at the same time as the injection operation, the paint is applied in a stamp manner and it can be identified that the injection has been completed. Further, since the paint impregnated portion 10 projects from the tip 2a of the bar-shaped main body 2, the paint impregnated portion 10 is lightly applied to the body surface so that the injection needle 23 does not hit the body surface, so that the paint is widely applied. Thus, for example, a severe pig can be identified.

On the other hand, when the spray container 11 is provided, the spray type coating can be performed. Alternatively, it may be used in combination with the paint impregnation unit 10. The spray type is divided into three types. That is, it is divided into a structure in which the spray operation unit is attached to the spray container 11 and a structure in which the spray operation unit is attached to the tip of the bar-shaped main body 2.

The latter is divided into a structure that is automatically sprayed by hitting the body surface of the animal with the spray operation unit and a structure that is sprayed by operating a trigger at hand.

FIG. 5 shows an embodiment in which a normal spray container 11 is attached to the rear side of the bar-shaped body 2 via a holder 12, and a spray operating portion, that is, a pusher 13 is attached to the tip of the spray container 11. . An extension pipe 17 is connected to the ejection port 13a of the pusher 13, and the tip of the extension pipe 17 is guided to the tip 2a of the bar-shaped body 2.

Therefore, when the pusher 13 is pressed, the paint ejected from the ejection port 13a passes through the extension pipe 17 and ejects from the tip toward the animal, and the identification paint is sprayed on the animal body surface. To be done. In order to improve operability, a structure in which the pusher 13 is pushed through the connecting member 27 when the trigger 26 provided near the handle 1 is pulled is suitable.

In FIG. 6, a spray operation portion (pusher) 15 is arranged so as to slightly protrude from the tip 2a of the bar-shaped body 2 and the syringe holder 25, and the spray operation portion 15 has a spray port 15a and the other end thereof. An extension pipe 14 is connected to the container 11. Therefore, the interior of the extension pipe 14 is also in continuous communication with the interior of the spray container 11, and is filled with the paint.

When the handle 1 is held in the hand and the spray operating portion 15 at the tip of the bar-shaped main body 2 is pressed against the body surface of the animal, the spray operating portion 15 is pushed and the spout 15 is ejected.
Paint is jetted from a and sprayed on the surface of the animal's body.
It should be noted that when a large cap-shaped body is attached to the spray operation unit 15, the spray operation unit is stably hit against the body surface of the animal, and the spray operation is performed stably and smoothly.

As shown in FIG. 6, in the structure in which the spray operating section 15 is pushed to hit the animal body surface and the spray is performed, the spray is always performed when the injection is performed. .

On the other hand, when the spray operating portion 15 is operated by the trigger 26 at hand via the wire 16 as shown in FIG. 7, it is independent of the injection operation and is specially applied to, for example, only severely ill animals. You can also do a spray of. In this case, the spray operation part 15 is retracted from the tip 2a of the bar-shaped body 2 or the syringe holder 25 so that the spray operation part 15 does not hit the body surface of the animal.

In the illustrated embodiment, for convenience of description, the slider 22 having the paint impregnated portion 10, the compression coil spring 21, and the tubular portion 20 are arranged outside the bar-shaped main body 2, but the bar-shaped main body 2 is provided. If 2 is formed into a tubular or semi-cylindrical hollow body and the slider 22, the compression coil spring 21, the supporting tubular portion 20 and the like are incorporated therein, the structure of the entire apparatus is simplified and the external shape is compact. Becomes
At this time, the extension pipes 14 and 17 are structured to pass through the outside of the bar-shaped main body 2.

In the above embodiment, the stamper type paint impregnation part 10 and the spray container 11 are used together, but only the stamper type or the spray type is used.
A structure equipped with only one of them is also possible.

Further, a structure in which the rear portion of the bar-shaped main body 2 has a semi-cylindrical shape and the spray container 11 is set therein is also effective in miniaturization. If the screw rod 6 is a hollow body such as a bellows pipe for gas or water, it is effective for weight reduction. The bar-shaped body 2 and the slider 22 may be made of a light metal such as aluminum.

Since the injection liquid is pushed out from the needle, it is possible to instantly inject the liquid in a standing posture, and it is possible to prevent fatigue and prevent back pain.

According to the second aspect, the nut 7 screwed to the threaded rod 6 connected to the plunger of the syringe 3 is rotated so that the nut 7 is separated from the stopper 8 by a predetermined distance S. Can be weighed and injected in multiple doses.

Since the screw rod 6 is locked by the lock means 9 and pulled backward by the spring means,
Only a forward movement of the plunger allows continuous injection of a fixed amount of drug solution. When the locking means 9 is released after the liquid medicine in the syringe 3 is completely used, the plunger is retracted by the spring means 4, so that the injection liquid can be sucked into the syringe 3.

According to the third aspect, the paint impregnating portion 10 is provided on the tip end side of the bar-shaped main body 2 so as to retreat against the elasticity. When it is pressed against the body surface, the paint is applied, and it can be applied continuously and reliably with the injection work.
