Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is useful for use in injecting animals, particularly pigs and cattle, and is highly safe for use in injecting other animals. It is about.

[0002]

2. Description of the Related Art When breeding animals, it is widely practiced to prevent the animals from getting sick or to inject a drug solution when they become sick, especially in pig farms. He pays close attention to the disease to make the meat available for consumption. Also, when injecting a drug solution,
Care is taken to inject the drug solution carefully so as not to break the injection needle. However, an accident has occurred in which pigs suffer pain when pierced with the injection needle and frequently break the injection needle.

[0003] When the injection needle breaks, the injection needle enters the body of the animal and moves in the body. Therefore, if the injection needle is used as it is, it is extremely dangerous. That is the current situation. Therefore, pig farmers are eager to take some measures, because slaughtering pigs that have been reared without feeding them is a great loss.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned prior art, and when the injection needle is broken when an injection is given to an animal such as a pig, the injection needle is kept in the body of the pig or the like. It is an object of the present invention to provide a veterinary injection needle which can be prevented from entering the needle.

[0005]

SUMMARY OF THE INVENTION The object of the present invention, which has been made to solve the above-mentioned problems, is to provide a veterinary injection needle having an attachment cylinder attached to the tip of a cylinder of a syringe at the rear end of the needle member. Alternatively, a mounting cylinder is forcibly press-fitted into the tip of the cylinder, and a sphere, ring, flange, or the like larger than the thickness of the needle member is formed near the joint of the needle member with the mounting cylinder. Whether or not an entry prevention member for preventing the broken needle member from entering the animal body is provided integrally with the needle member,
Alternatively, the rear side of the penetration preventing member of the needle member is formed as a thin easily breakable portion.

That is, in the injection needle of the present invention, the animal violates while the needle member is stabbed into a required part of the animal to give an injection.
When the needle member is about to break, the needle member is broken behind the entry preventing member or from the easily breakable portion so that the needle member can be prevented from entering further in a state where the entry preventing member is in contact with the skin of the animal. If the needle member is pulled out of the animal after the breakage by pinching the entry preventing member after the breakage, there is almost no possibility that the needle member enters the animal and moves through the body.

[0007] Further, if the entry preventing member is made of a synthetic resin colored in an appropriate color, it becomes convenient not only in the production but also in the handling of the animal injection needle of the present invention.

[0008]

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 a state in which the injection needle of the present invention is mounted on a cylinder of a syringe, and FIG. 2 is an enlarged front view of an easily breakable portion.

In FIG. 1, reference numeral 1 denotes a needle member, which has a tip 1a sharply formed so as to pierce the body to be injected, and a mounting cylinder 2 attached to the tip of a cylinder C of a syringe at the rear end. At the same time, the joint portion with the mounting cylinder 2 is formed thinner than the needle member main body to form the easily breakable portion 1b. Reference numeral 3 denotes a spherical intrusion prevention member integrally attached to the needle member 1 at the tip of the easily breakable portion 1b of the needle member 1, and is usually made of a synthetic resin having an appropriate coloring or pattern. In the drawing, P is a piston rod or plunger of the cylinder C.

In the above example, the entry preventing member 3
In the present invention, the easily breakable portion 1b is not provided, but this portion may be formed to have the same thickness as the needle member main body. Further, although the shape of the entry preventing member 3 is spherical, the shape is not limited to a spherical shape, but may be a ring shape, a flange shape, or the like. In short, if the needle member 1 is broken behind the penetration preventing member 3 or from the easily breakable portion 1b, any shape may be used as long as the needle member 1 can be prevented from entering the inside of the injection body. .
Also, if the entry preventing member 3 is colored or has a pattern in an appropriate color, it is easy for an operator to see and is very convenient in handling.

The veterinary injection needle of the present invention configured as described above is mounted on the distal end portion of the cylinder C of the syringe with the mounting cylinder 2, and the medicinal solution for injection is placed in the cylinder C. The part 1a is pierced into a required portion of the animal to be injected, and is used to inject the drug solution in the cylinder C into the body of the animal by pressing the piston rod or the plunger P. When the force exceeds a certain level, the needle member 1 moves behind the penetration preventing member 3 or
Even if the needle member 1 breaks from the easily breakable portion 1b and attempts to enter the animal body, the further entry is prevented when the entry prevention member 3 comes into contact with the animal's skin. There is no danger of getting into the body, and if the entry prevention member 3 is pinched and pulled, the needle member 1 can be easily removed.

[0012] Therefore, even if the animal is a pig or a cow, it is not necessary to carry out slaughter and disposal as in the conventional case, which is extremely advantageous in management at a pig farm or the like.

[0013]

The present invention is as described above, and a mounting cylinder to be attached to the distal end of a cylinder of a syringe is integrally formed at the rear end side of the needle member, or a mounting cylinder is mounted at the distal end of the cylinder. Forcibly press-fitting, near the junction of the needle member with the mounting cylinder, provided with an intrusion prevention member to function as an easily breakable portion, or forming the vicinity of the junction in a thin easily breakable portion, On the distal end side of the easily breakable portion, a needle preventing member is provided integrally with the needle member for preventing the broken needle member having a spherical shape, ring shape, flange shape or the like larger than the thickness of the needle member from entering the animal body. If it is used, if the animal is violent at the time of injection and the needle member is likely to break,
The needle member breaks from the easily breakable portion, and even if the needle member attempts to enter the body of the animal, when the penetration preventing member comes into contact with the skin of the animal, the needle member is prevented from further entering. There is no danger that the needle member will enter the animal, and after the breakage, the needle member can be easily removed from the animal if the entry prevention member is pinched and pulled.

Therefore, the present invention is suitable as an injection needle used for injecting pigs raised in a pig farm or the like, and it is necessary to carry out slaughter and disposal treatment caused by breakage of the needle member which has frequently occurred in the past. This is extremely advantageous in terms of management because it disappears. The injection needle of the present invention is not limited to pigs, and is extremely useful when used for other animals.
