DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention is useful for injecting animals, particularly pigs and cattle, which are livestock animals, and is safe for use when injecting other animals. For high animal needles.

[0002]

2. Description of the Related Art When breeding animals, it is widely practiced to inject a drug solution for the prevention of diseases of the animals or for the treatment of various diseases. In animal farms, the meat of the animal products is used for edible foods, so it is necessary to treat various diseases with great care. In addition, when injecting a drug solution, the drug solution is carefully injected so that the needle is not broken. An accident has occurred.

[0003] If the injection needle breaks, the injection needle enters the body of the animal and moves through the body. Therefore, it is extremely dangerous to feed the food as it is. It is the current situation. Therefore, for livestock industry such as pig farmers, slaughtering livestock animals such as pigs reared without feeding them is a great loss, and there is an urgent need for some measures to be taken.

[0004] In view of the above-mentioned current situation, the inventor of the present invention has previously described the case where a livestock animal such as a pig is given an injection.
Japanese Patent Application No. 9-213872 discloses an animal injection needle which can prevent the injection needle from entering an animal body such as a pig even if the injection needle is broken.
No. is proposed.

In the veterinary injection needle proposed by the inventor of the present invention, a mounting cylinder to be attached to the tip of a cylinder of a syringe is integrally formed at the rear end side of the needle member, or In a veterinary injection needle in which a mounting cylinder is forcibly press-fitted into a portion and a needle member is mounted on the mounting cylinder, a spherical or ring-shaped portion larger than the thickness of the needle member is provided near the joint of the needle member and the mounting cylinder. A penetrating prevention member for preventing a broken needle member having a flange shape or the like from penetrating into the body of an animal is provided integrally with the needle member. A structure formed in the easily breakable portion is also proposed. This injection needle is an extremely useful one that can effectively prevent the tip of the broken needle from entering the animal body by the action of the entry prevention member, even if it breaks during injection. It was confirmed that there was a problem to be solved.

That is, the penetration preventing member for preventing the broken needle member from entering the animal body is formed into a substantially spherical shape with a synthetic resin material, and then pressed into the needle member by using a press. However, the insertion must be positioned a little away from the base of the needle member (near the boundary between the mounting cylinder and the needle member) (the position in front of the needle member). The problem is that it is not possible to perform the above operation, and if it is inserted too much, it must be corrected to return the position.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has been described in connection with the case where the above-described penetration preventing member is inserted into a needle member.
An object of the present invention is to provide an animal injection needle provided with an entry preventing member having a function of easily performing positioning.

[0008]

SUMMARY OF THE INVENTION An object of the present invention, which has been made to solve the above-mentioned problems, is to provide an injection needle for an animal having a mounting cylinder connected to the tip of a cylinder of a syringe at the rear end of the needle member. In the needle, an intrusion prevention member having a positioning projection protruding rearward to prevent a further insertion by hitting a front end of the mounting cylinder and preventing further insertion is provided near the coupling portion between the needle member and the mounting cylinder. The rear part of the prevention member is an easily breakable portion.

[0009] In the case of an injection needle of the present invention, when an animal violates and breaks the needle member during injection while piercing the required portion of the animal with the needle member, the needle member is placed behind the penetration preventing member. The needle member is broken from the set easily breakable portion, and prevents further penetration of the needle member in a state where the entry prevention member is in contact with the skin of the animal.
Therefore, in the injection needle of the present invention, even if the needle member breaks during the injection, the entry prevention member can be picked up and the needle member can be pulled out from the animal, so that there is a possibility that the needle member may enter the animal body and move in the body. There is nothing.

[0010] In particular, in the injection needle of the present invention, since the penetration preventing member is provided with the rearward projecting portion serving as a positioning leg when inserted into the needle member, the insertion preventing member is inserted into the needle member.
Positioning is facilitated, and the penetration preventing member cannot be inserted to the joint portion between the needle member and the mounting cylinder, so that the gap necessarily formed between the penetration preventing member and the mounting cylinder formed therein is easily formed. The breakable portion can be set, and even when the easily breakable portion is formed to be thin, the easily breakable portion is not covered by the entry preventing member. Since the entry preventing member is made of a synthetic resin colored in an appropriate color, it serves as a mark for the position of the needle when it is broken, so that the handling is convenient.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of an animal injection needle of the present invention will be described with reference to the drawings. FIG. 1 is a front view of an example of the injection needle of the present invention, and FIG. 2 is an enlarged front view of an easily broken portion.

In FIG. 1, reference numeral 1 denotes a needle member, a tip 1a of which is sharply formed so as to pierce an object to be injected, and a rear end of which is attached to a tip of a cylinder (not shown) of a syringe. The mounting cylinder 2 is integrally connected to the distal end side 2a of the mounting cylinder 2. The joint portion of the needle member 1 with the mounting cylinder 2 is made thinner than the needle member main body, or this portion is made an easily breakable portion 1b. Numeral 3 denotes a generally spherical entry prevention member which is inserted and attached before the easily breakable portion 1b of the needle member 1, and has a leg-shaped positioning acting on the rear surface thereof as an insertion stopper for the needle member 1. The projection 3a is usually formed of a synthetic resin having an appropriate color or pattern, but may be made of another material.

In the above-described example, the easily breakable portion 1b is formed to be slender (smaller in diameter than the needle member 1) through the step after the entry preventing member 3, but in the present invention, the easily breakable portion 1b is formed.
It is also possible to form the easily breakable portion 1b without forming the slender portion 1b with the same thickness as the needle member main body or by adding a bump-like stepped portion so as to be thicker than the needle member main body. In addition, the shape of the entry preventing member 3 is substantially spherical in the illustrated example, but is not limited to a spherical shape, and may be a ring shape, a flange shape, or the like, and may include a positioning projection 3a on the rear surface side. Just fine. In short, the needle member 1 can enter the animal only up to the front of the entry preventing member 3, and if the needle member 1 breaks from the easily breakable portion 1b located behind the entry preventing member 3 of the needle member 1, Any shape may be used as long as the member 1 can be prevented from entering the body of the animal. If the anti-invasion member 3 is mixed with an antibacterial agent, or is colored or patterned with an appropriate color, it is possible to prevent propagation of various germs and the like by the intrusion prevention member 3 and also to the eyes of workers. Because it is also easy to attach, it is preferable for hygiene, and even if the needle member breaks, it becomes a mark of the position of the needle member,
Therefore, it is extremely convenient in handling. Further, it is preferable that the needle member 1 and the intrusion preventing member 3 are made of a material having heat resistance and the material does not change due to boiling disinfection or the like.

The animal needle of the present invention constructed as described above is attached to the distal end of a cylinder (not shown) of the syringe at the rear end side 2b of the mounting cylinder 2 in the same manner as the conventional injection needle. Putting a drug solution for injection into the cylinder, piercing the tip 1a of the needle member 1 into a required part of the animal to be injected,
It is used to inject the drug solution in the cylinder C into the body of the animal by pushing the piston rod or plunger of the cylinder.
Prevents penetration of the animal into the body at a depth greater than that, and even if the animal breaks down during injection and the needle member 1 breaks from the easily breakable portion 1b behind the penetration preventing member 3, the penetration preventing member 3 When it comes into contact with the skin of the animal, further entry is prevented, so there is no danger that the needle member 1 will enter the body of the animal anymore, and if the entry prevention member 3 is pinched and pulled, the needle member 1 can be simplified. Can be removed.

[0015]

As described above, the present invention relates to an animal injection needle having a mounting cylinder connected to the tip of a cylinder of a syringe at the rear end of the needle member, in the vicinity of the joint between the needle member and the mounting cylinder. And an insertion prevention member having a positioning projection that faces the front end of the mounting cylinder and prevents further insertion is inserted and provided, so that the injection needle is deeper than the position of the penetration prevention member. It is safe because it does not pierce the needle, and even if the animal breaks during injection and the needle member breaks, the break always occurs in the easily breakable part, and the rear end of the needle member remaining on the animal side is indispensable. However, since there is an intrusion prevention member, the needle member can be prevented from further entering the body of the animal, and after breakage, the needle member can be easily removed from the animal by picking and pulling the intrusion prevention member. Of the effect that can be removed Or, there are the following specific effect.

That is, since the entry preventing member provided on the injection needle of the present invention has the positioning projection on the rear surface side, there is an advantage that the positioning can be easily performed when the entry preventing member is inserted into the needle member. In addition, the gap between the rear surface of the penetration preventing member of the needle member and the front surface of the mounting cylinder can be set as the easily breakable portion, and since the penetration preventing member does not overlap the easily breakable portion, the function of the easily breakable portion may be impaired. There is no such thing at all.

Therefore, the present invention is suitable as an injection needle used for injecting livestock animals such as pigs kept in a livestock farm such as a pig farm, and is caused by breakage of the needle member which has frequently occurred in the past. This eliminates the need for slaughter and disposal, which is extremely advantageous for management. The same effect as in the above example can be obtained when the injection needle of the present invention is used for animals other than the above-mentioned livestock animals, for example, racehorses, zoo animals, and other animals.
