Description

Injector for Domestic Animals

The present invention relates to an animal syringe which can be effectively used for preventing or combating various diseases of livestock in a livestock farm or a livestock farm that raises a large amount of pigs or cattle.

In particular, the present invention improves the convenience of injection and prevents the needle from being easily broken while performing continuous injection to all animals such as livestock, while preventing the inflow of air into the syringe and confirming the injected animal. The emphasis is on enabling this to prevent duplicate injections.

As is known, general animal syringes contain only a single dose of the chemical solution contained in the syringe, so when injecting a large number of animals, it is necessary to receive the chemical solution in the syringe every time. In addition, the animals are severely fluctuated during the injection, so the injection is not easy and the needle is bent or broken. According to the present invention, the syringe for animals (utility model notification No. 97-475) devised to improve the problem in consideration of such a problem, as the needle enters the skin of the animal, the piston rod of the syringe is pushed and the chemical liquid is injected. At this time, the guide piece (contact disc) formed around the needle is in close contact with the skin of the animal to ensure a stable injection. In addition, the structure is further complemented to the structure of the medicine container is mounted on the user's body portion and to enable the repeated operation of the syringe cylinder by the spring to allow continuous injection to a large number of animals (Utility Model Registration No. 134310) I have suggested. However, the above-mentioned pre-registered utility model of the present inventors have some effects in easy and continuous injections of animals with high movement, but in the case of pigs, they move particularly heavily, so that the guide pieces which are in close contact with the skin of the pigs are caused by the fluctuations of the pigs. Since the needle is bent or broken due to slipping, the guide piece alone cannot be expected to provide complete protection of the needle. In the case of Registration Utility Model No. 134310, the medicine container is mounted on the user's arm, which makes the operation unnatural and inconvenient. In particular, by connecting the medicine container and the syringe body with a tube for a long time has been pointed out the problem that the tube is hindered in the workability. In addition, the syringes of the above inventions have a one-way grip structure, so that in the case of a severely moving animal such as a pig, the posture or injection site for the easy injection is limited, which causes difficulty in working. On the other hand, since there is no marker structure for the injected animals, when the injected pigs are mixed with the uninjected pigs, the injections are repeated twice or more, resulting in side effects and waste of drugs. .

The syringe for animals of the present invention is capable of continuous injection by the repeated operation of the syringe body and the sliding tube interlocked with the spring, and the adhesion disc for stably maintaining the syringe body while being in close contact with the skin of the animal in front of the syringe body. The configuration adopts the above-described prior art of the applicant. In the present invention, by providing a chemical container in the rear of the syringe body provides a reasonable coupling structure of the chemical container according to the continuous injection. In particular, the chemical liquid container can be selectively coupled vertically or horizontally to provide various means of use according to working conditions. In order to prevent the needle from being easily broken, a needle protection tube is extended around the midpoint of the needle to the front of the syringe body, and a stamp is formed on the front surface of the close contact disc provided to maintain the stability of the syringe body. By stamping the animal's skin, it is possible to identify animals that have been injected. In addition, the chemical liquid container of the present invention constitutes a piston descending by its own weight to the inside thereof, so that when the chemical liquid container is vertically coupled, the bottom part of the piston is brought into close contact with the upper surface of the chemical liquid until the liquid is completely exhausted. To prevent the inflow into the chemical chamber.

A piston rod 13 having a spring 11 and a chemical liquid passage 12 at an inner side of the syringe body 10 having a handle 20 at one end thereof and a spring rod 11 resilient to the outer periphery of the rear end of the syringe body 10. The conventional structure consisting of the sliding tube 30 provided and the close contact plate 15 formed in front of the syringe body 10 is adopted as it is. In the present invention, the handle 20 is configured to be folded while being rotated around the pin 21, and forms the spiral member 31 at the rear end of the sliding tube (30). The chemical liquid container 100 is coupled to one end of the connection pipe 70 to be mounted on the rear of the syringe body 10, so that it can be selectively coupled vertically or horizontally. In front of the syringe body 10 is a series of related structures in which a bent frame 41 is integrally coupled to the needle protection tube 40 formed integrally, and a stamp 50 is attached to the front edge of the outer peripheral adhesion plate 15. It is composed.

The chemical liquid container 100 is generally configured to have a structure similar to a cylinder of a syringe, that is, constitutes a piston 101 which descends to its own weight inside. In addition, the chemical liquid container 100 coupled to the connecting pipe 70 and mounted to the rear of the syringe body 10 is a spiral formed behind the sliding pipe 30 by using a predetermined push rod and connector 60 as shown in FIG. 1. It may be coupled vertically to the member 31 or may be directly coupled horizontally in Figure 2 and in the state in which the push rod and connector 60 are excluded. And the push rod and connector (60) provided in the vertical coupling as shown in Figure 1 is provided with a chemical liquid supply passage 61 on the inside, one end of the connection screw tube 62 and the upper screw connection portion (63) are respectively constructed. That is, during use, the screw is first screwed into the spiral member 31 of the sliding tube 30 by using the connecting screw tube 62 formed on the front side of the push rod and connector 60, and then the chemical coupling tube is connected to the screw coupling portion 63 of the upper end. By screwing the lower end of the coupling pipe (70) to which the 100 is coupled, the chemical liquid container (100) is mounted in the vertical state at the rear of the syringe body (10). Of course, the chemical supply passage 61 at this time is in communication with the inlet of the chemical liquid passage 12 of the piston rod (13). And when the chemical liquid container 100 is horizontally coupled as shown in Figure 2 is coupled directly to the connecting pipe 70 is coupled to the spiral member 31 in a horizontal state in this case, in this case, the chemical liquid container 100 and the connection thereof The entire tube 70 will have the function of a handle and push rod.

Reference numeral 12 ′ denotes a chemical chamber, 51 a protective cap 80 a chemical control lever, 90 a needle, and V1 and V2 a check valve.

The drug solution container 100 of the present invention temporarily binds a conventional needle to the drug solution outlet side, and then, by using the needle to extract and receive the drug solution contained in the injection container and then to remove and remove the temporarily combined needles When the chemical liquid container 100 is to be vertically coupled, as described above, it is used to be coupled to the spiral member 63 of the rod and connector 60, and on the other hand, when the chemical liquid container 100 is to be horizontally coupled, the connection pipe ( The coupling structure is selectively configured by directly coupling 70) to the spiral member 31.

The action of the piston rod 13, the sliding tube 30 and the check valve (V1) (V2) at the time of injection is similar to the above-described prior art of the present inventors, but by the characteristic chemical liquid container 100 coupling structure of the present invention The gripping means is different. That is, in the state in which the chemical container 100 is vertically coupled as shown in FIG. 1, the handle 20 and the push rod and connector 60 are used as one hand holds the pistol, and the chemical container 100 is horizontal as shown in FIG. 2. When combined, use it as a handle by grasping the knife. When the chemical liquid container 100 is vertically coupled as shown in FIG. 1, the handle 20 is rotated in a vertical state with the pin 21 as a single axis. Then, pushing the handle 20 to the front push the push rod and connector 60 forward and at the same time when the injection needle (90) is injected into the skin of the animal sliding tube 30 connected to the push rod and connector (60) And the piston rod 13 moves forward to inject the chemical liquid in the chemical chamber 12 'into the animal skin through the needle 90. At this time, one end of the check valve (V1) is opened to maintain the exit check valve (V2) of the chemical liquid passage (12) closed. Then, when the pressing force of the push rod and connector 60 is released, the sliding pipe 30 moves backward by the elasticity of the spring 11 and accordingly, the push rod and the connector 60 and the piston rod 13 interlocked with the spring 11 are returned to their original positions. At this time, the chemical liquid introduced into the chemical liquid passage 12 again flows into the chemical liquid chamber 12 'while pushing the check valve V1 by the reflective action of the rearward movement of the piston rod 13 to wait for the next injection. do. That is, the chemical liquid in the chemical liquid chamber 12 'is injected into the animal, and then the chemical liquid in the chemical liquid passage 12 flows back into the chemical liquid chamber 12' at the same time as the piston rod 13 moves backward. The chemical liquid in the 100 is continuously filled into the chemical liquid passage 12 through the chemical liquid supply passage 61 of the push rod and connector 60 to enable continuous injection operation. Of course, the continuous supply action of the chemical liquid according to the action of the piston rod 13 is similar to the prior art, but in the present invention, the piston 101 is lowered to its own weight as the chemical liquid in the chemical container 100 is reduced at each injection. Always keep in contact with the surface of the chemical solution.

And once you have exhausted the chemical solution again to combine the needles temporarily and refill the chemical solution to use repeatedly.

On the other hand, in the state in which the chemical liquid container 100 is horizontally coupled as shown in FIG. 2, the push rod and connector 60 are excluded and the chemical liquid container 100 and the connection pipe 70 are used as holding means. That is, holding the medicine container 100 and the connection tube 70 together by hand and injecting the needle 90 to the skin of the animal while maintaining the syringe body 10 in the horizontal direction the connection tube 70 and The chemical liquid container 100 pushes the sliding tube 30 and the piston rod 13 connected thereto to the front to inject the chemical liquid in the chemical chamber 12 'into the skin of the animal by the above-described action. When the 10 is removed from the skin of the animal, the pressure of the piston rod 13 is released, so that the piston rod 13 and the sliding tube 30 and the connecting tube 70 and the chemical liquid mounted thereon are caused by the elasticity of the spring 11. The barrel (100) is also returned to its original state, waiting for the next scanning operation. The connection pipe 70 of the present invention has a function to secure the grip portion when the chemical liquid container 100 is horizontally coupled, and particularly to protect the weak connection portion with the spiral member 30 of the piston rod 13. In addition, when using a combination of such a chemical container (100) horizontally pushed up the handle (20) deployed downward so that the work is not inconvenient. On the other hand, the close contact plate 15 coupled to the front of the syringe body 10 is in close contact with the skin of the animal at the time of injection to maintain a stable syringe body 10 as a whole to perform an extremely stable injection, in particular the present invention In the seal 50 is attached to the front of the close contact plate 15 is to perform the stamp on the skin of the animal at the same time. The stamp 50 contains ink (mainly red), and when the close contact 15 is in close contact with the skin of the animal, the stamp 50 is stamped on the skin of the animal. It can be identified to prevent duplicate injection. In addition, after the injection operation, if you want to store the syringe to cover the protective cap 51 to prevent damage to the stamp (50). And the present invention is a needle bar (40) is extended and coupled to the front of the syringe body 10, which is the needle 90 is bent when the close contact plate 15 is slipped by the severe movement of the animal In the present invention, since the bending frame 41 is integrally bent inwardly in front of the needle protection tube 40 to support the center portion of the length of the needle 90, the needle does not bend much. ) To prevent breakage.

Meanwhile, in FIG. 3A, when the chemical liquid container 100 is used vertically in the present invention and the last chemical liquid is discharged toward the chemical liquid chamber 12 ′ in the inclined state, the chemical liquid chamber 12 ′ is used. ), Which is compared with the case where air is introduced without the piston as shown in FIG. 3B. That is, in the present invention, as shown in Figure 3a, the chemical container 100 is coupled to the piston 101 which descends to its own weight inside thereof, and also maintains the state always in contact with the surface of the chemical liquid. Therefore, when the liquid decreases and the water surface becomes unfamiliar, it descends to its own weight, thereby achieving continuous contact with the upper surface of the chemical. In other words, this action prevents the formation of an air layer on the upper part of the chemical liquid due to the continuous contact with the upper surface of the chemical liquid due to the lowering of the piston 101. Thus, the last remaining chemical liquid is discharged toward the chemical chamber 12 '. When the air is prevented from entering the chemical chamber 12 'together. This is because the upper surface of the chemical liquid is always in contact with the air, as can be seen in the state without the configuration of the piston in the chemical liquid container 100 as shown in Figure 3b, when the last chemical liquid is discharged toward the chemical chamber is discharged obliquely to the outlet As part of the outlet is opened, air is also introduced along with the chemical solution as shown by the dotted arrows. Of course, if the liquid container 100 is exactly horizontal, regardless of the presence of the piston 101, the simultaneous inflow of air is not made, but when the injection liquid is almost exhausted, pay careful attention to maintain the liquid container 100 horizontally It is almost impossible to tilt. Therefore, the air inlet blocking structure of the present invention is to prevent side effects due to the bubbles are formed in the chemical liquid.

As described above, the present invention provides ease of operation by mounting the medicine container in the rear of the syringe body, and in particular, by selectively combining the medicine bottle with the vertical or horizontal, etc. to provide a variety of means for holding the syringe to work conditions or types of livestock In addition, it is possible to work in a convenient posture according to the injection site, while preventing the breakage of the needle and providing a seal means for checking the injection, etc., with excellent workability and economic effects and the closing of the animal due to the overlap injection is corrected.
