Description

Continuous injector for animals {Animal Consecutive injector}

The present invention relates to a continuous syringe for animals, and more particularly, when administering an injection drug solution for prevention or treatment to livestock such as cattle or domesticated animals, safely and quickly administering the injection drug solution to a number of animals from a distance. It relates to a continuous syringe for animals configured to be able to do.

Many animals raised in livestock such as cows or zoos are regularly or irregularly administered vaccinations to prevent diseases, including infectious diseases, and are also administered with injections of treatments when they are sick.

Before the outbreak of foot-and-mouth disease in Korea in 2010, vaccination against a specific disease had been carried out intermittently for small numbers of farms as needed. Vaccination against foot-and-mouth disease is being administered to all heads.

In this way, when the foot-and-mouth disease vaccination season comes, the user has to deal with a lot of cows in a short period of time, and in the case of adult voice actors, they are often over 10 times the adult weight, and depending on the individual, there are cases where they are ferocious. When using a syringe to get close to a cow and give an injection, the user's safety has become a problem, such as being kicked by the cow's hind feet.

When administering preventive vaccines or treatments to many animals with a syringe, if you install an injection medicine bottle and operate the handle to inject many animals in a short time, the drug is automatically sprayed and continuous injection is possible (gun ) type of continuous syringe is mainly used.

However, such a gun-type continuous syringe should administer injections in close proximity to animals, but large animals such as cows may be surprised and move violently when administering the injection solution, so it may not be easy to administer the injection solution Injection needles can seriously injure animals.

In addition, safety accidents frequently occur when a person who is trying to administer an injection drug solution is bumped into or stumbled upon by animals.

In order to solve this problem, a technique for an injection device capable of administering an injection drug solution to animals at a distance has been developed.

As an example, in Patent Registration No. 10-2209279 (hereinafter referred to as 'prior art'), as shown in FIG. A continuous syringe assisting device for animals configured to be able to be used is presented.

The prior art continuous injector auxiliary device for animals shown in FIG. 1 has the advantage of being able to more safely administer an injection drug solution at a certain distance from the animal.

However, the continuous syringe assisting device for animals shown in the prior art is provided with an additional extension tube 100 in front of the continuous syringe 10, so that a large amount of drug is wasted and the commercial continuous syringe 10 is assisted. There is also a problem that can be easily fatigued when administering an injection drug solution to animals due to the weight of the device mounted in the middle.

The assembled continuous syringe 1 for animals of the present invention can continuously administer the injection drug solution 11 to animals through the following steps, as shown in FIGS. 6 to 9 . 6 to 9 are drawings in which the elongated rod 410 is not shown in order to more clearly explain the operating principle of the continuous injector 1 for animals.

First, the injection drug container 10 is mounted on the injection drug solution mounting unit 120, and the piston moves forward and backward to prepare a continuous syringe 1 for animals in which the injection drug solution is filled in the syringe cylinder 110.

Subsequently, as a first step, as shown in FIG. 6 , the continuous syringe 1 for animals of the present invention is placed in contact with or close to the body A of the animal.

In the first step, since the injection needle 160 is located inside the syringe seating tube 310, the animals are not surprised even if the continuous injector 1 for animals contacts the body, so the injection drug solution can be easily administered.

In the second step, the handle 430 of the length extension rod 410 is advanced in the longitudinal direction, that is, in the animal direction.

In the second step, the pressure rod 210 and the syringe module 100 themselves advance in the longitudinal direction without relative movement between the syringe cylinder 110 and the piston 130 in the syringe module 100, so that the injection needle 160 This step is to stab the animal's body (A).

At this time, the syringe module 100 moves forward and becomes caught in the syringe module engaging portion 321 of the second slit 310 . The front spring support member 260 and the front stopper 240 are separated from each other and the spring 280 is compressed.

The third step is to further advance the handle 430 of the elongated rod 410 in the longitudinal direction, that is, in the animal direction so that the piston 130 advances in the syringe cylinder 110 to administer the injection drug solution 11 to the animal. This is the dosing step.

In the second step, since the syringe module 100 is caught on the syringe module locking part 321, the syringe cylinder 110 cannot advance further, so as shown in FIG. 7, the piston inside the syringe cylinder 110 As the 130 advances inside the syringe cylinder 110, the injection drug solution 11 inside the cylinder is administered to the body A of the animal.

Next, the fourth step is a step of removing the external force moving forward from the handle 430 of the length extension bar 410 and moving it in the opposite direction.

In this step, a restoring force is generated in the compressed spring 280 so that the spring 280 is tensioned, and as a result, the pressure rod 210 and the syringe module 100 themselves move relatively backward with respect to the syringe seating tube 310. do.

In the fourth step, the syringe module 100 moves up to the syringe backward movement limiting member 330, and the exposed injection needle 160 is placed inside the syringe seating tube 310 again.

At this time, since the syringe cylinder 110 and the piston 130 do not move relative to each other in the syringe module 100, the piston 130 is still located in front of the syringe cylinder 110 as in the third step.

In the fifth step, since the external force is removed, the spring 280 is additionally tensioned by the restoring force so that the front spring support member 260 contacts or comes closest to the front stopper 240 as in the first step. do.

In this step, since the backward movement of the syringe cylinder 110 is limited, the piston 130 inside the syringe cylinder 110 moves relatively backward, and the injection liquid 11 is inside the syringe cylinder 110. is introduced

That is, when the fifth step is completed, the continuous injector 1 for animals of the present invention becomes a step capable of administering an injection drug solution to the animal as in the first step.

Therefore, the continuous injector 1 for animals of the present invention can rapidly and safely administer the injection liquid 11 to animals while sequentially repeating the first step to the fifth step.
