Description

Multi-needle for injecting veterinary medicine {Multi-needle for injecting veterinary medicine}

The present invention relates to a multi-needle for veterinary drug injection. More particularly, the present invention relates to a multi-needle for veterinary medicine injection having a needle of a predetermined diameter and length to administer a drug in the blood of an animal, particularly a large animal such as a cow or a pig.

In order to inject a conventional veterinary medicine into the animal, a single needle having a single needle or a needleless injection developed to reduce the side effects thereof was used. The mononuclear needles used for veterinary drug injection were required to be inserted into the target precisely according to the purpose because the target position is the muscle of the animal (muscle or intradermal or subcutaneous) and the needle diameter and length are long. However, singular needles have been inadequately injected at a certain location, such as animal breeders or veterinarians, such as zookeepers or veterinarians, but the position or depth of injection is not constant. As a result, side-effects such as granulomas and purulents were developed when the single needle was used, and an economic loss occurred as the side-effects were discarded at the time of shipment.

Acupuncture has been developed as an alternative to single needles and is a method of injecting drugs into the animal's intradermal layer at high pressure applied instantaneously. However, in the case of acupuncture injections, the drug may enter the muscles due to the failure of pressure control. Since the different types of immune cells are different between muscles and intradermal cells, non-acupuncture injections with the intradermal layer inserted into the muscles have a very low titer when the drug is injected into the muscles, making it difficult to cope with the target disease. There was a problem that caused the occurrence.

On the other hand, the conventional method of injecting a number of fine holes in the skin of the human body, the drug is injected into the body to remove various skin problems such as wrinkles, blemishes, blemishes, stretch marks, acne, freckles, pigmentation, and hair health It is widely used to maintain and improve hair loss, and to apply it to obesity treatment.

In this procedure, the multi-needle in which the plurality of needles are inserted into the skin of the human body through the multi-holes may vary in use depending on the thickness of the needles. For example, in the case of a human body having a relatively soft epidermal layer and a shallow depth to the point where the drug is injected, a small amount of drug was possible even if the needle diameter was small.
The structure and shape of the multi-needle and the like are disclosed in Korean Patent Publication No. 10-2015-0122367, Korean Patent Publication No. 10-2015-0018336, and the like.

However, the conventional multi-needle for human body has a difficulty in efficient drug delivery because of the small diameter or short length of the needle for use in the treatment of animals. In addition, in the case of animals, the epidermis is harder and thicker than the human body, and thus, injection of the needle is difficult because the needle is not inserted into the target point where the drug is injected, such as the intradermal layer, and in some cases, the needle of the needle is broken. . In the case of the multineedle for animals, it is required that the needle needle has a larger diameter and a longer length than the multineedle for human surgery.

In an exemplary embodiment, the cap 450 may have a lower end communicating with the second through hole 410 and an upper end extending from the hub 400, and the lower end may have a diameter larger than that of the upper end.

As shown in the figure, the diameter of the lower end of the cap 450 is larger than the diameter of the upper end, the side of the cap 450 may be formed to be inclined from the lower end. In the drawing, the upper end and the lower end have a circular shape, and the side surface is formed to be inclined, so that the shape of the cap 450 is substantially conical. However, the present invention is not limited thereto.

The cap portion 450 may have a form in which a portion of the cap portion 450 is extended from the outer wall 120 of the housing 100. The exposed cap portion 450 may support the needle 500 in contact with the epidermis of the animal when the veterinary drug injection multi-needle 10 is inserted into the epidermis of the animal. Here, the needle 500 penetrating through the cap portion 450 may be located in the blood through the skin of the animal. The predetermined drug delivered to the needle 500 through the drug injection unit 150, the drug receiving unit 290, and the internal flow path 250 may be injected into the blood of the animal.

The plurality of needles 500 may have one end fixed on the support 200, and the other end may extend toward the hub 400 to be exposed from the housing 100. One end of the needle 500 is inserted into and fixed to the second outlet 252 of the support 200, and the other end of the needle 500 passes through the first through hole 310 and the hub 400 of the fixing part 300. It may extend through the hole 410 and the cap 450. The other end of the needle 500 may be exposed from the hub 400, a part of which may be surrounded by the cap 450, and another part of the needle 500 may be exposed to the outside.

In the drawing, nine needles 500 are disposed, and one needle is disposed at the center and eight needles are disposed around the needles. The eight needles are arranged to be spaced apart by a predetermined distance from one needle disposed at the center so as to surround the plurality of needles 500 in the form of 3 × 3. The arrangement of the needle 500 is not limited thereto. Needle 500 may be included in various ways, including a greater number, or fewer. For example, 2x2, 4x4,? The needle 500 may be arranged in various ways, such as an arrangement of nxn, an arrangement of two lines, an arrangement of two rows, and a circular arrangement surrounding a circumference around a single needle.

According to one embodiment of the invention, the diameter of the needle 500 may have a range of 15 gauge (G) to 30 gauge (G).

Unlike the human body, animals have a relatively thick and hard epidermis. Typically, the needle of a human multi-needle has a diameter in the range of 30 gauge or more. In the case of multi-needle for human body, since the amount of drug that is required to be inoculated per dose is usually about 0.01 mL, even if the diameter of the needle is small, it may have sufficient efficacy.

On the other hand, for animals, a large diameter needle 500 is required because the amount of drug required per inoculation can range from 0.1 mL up to 4 mL. When the needle 500 of the veterinary medicine injection multi-needle 10 according to an embodiment of the present invention has a diameter of 30 gauge or more, the animal is not inoculated and the drug is not delivered to the animal having thick and hard skin, or 1 There is a problem in that the amount of drugs injected at the time of inoculation is insufficient to increase the time required for inoculation. In the case of animals, the inoculation time is long because the movement during the inoculation of the drug is not accurate because the drug injection is limited in the field use. That is, when used in animals, it is required to inject the desired amount of drug in a short time.

On the other hand, if the diameter of the needle 500 is 15 gauge or more, that is, the diameter is too large, there is a problem that the injected drug is refluxed again to accurately inject the desired amount of drug.

Therefore, the needle 500 according to an embodiment of the present invention has a diameter having the above range, so that the desired amount of drug can be accurately injected within a short time in a single inoculation. Preferably, the diameter of the needle 500 may be 20 gauge (G). However, it is not limited thereto.

In addition, according to an embodiment of the present invention, the length of the region dd exposed from the cap portion 450 of the needle 500 may have a range of 1.5 mm to 5 mm.

In the human body, since the thickness of the dermal layer is 0.5 mm to 1.0 mm, even if the length of the area dd exposed from the cap portion 450 of the needle 500 is short, drug injection is possible. On the other hand, in the case of animals, since the thickness of the dermal layer is about 2.5 mm, if the length of the exposed area dd from the cap portion 450 of the needle 500 is shorter than the above-mentioned range, the drug to the intradermal layer to be injected There is a problem that the needle 500 does not reach. In addition, when the length of the region dd of the needle 500 is too long, the needle 500 may be inserted into the subcutaneous layer or the muscle layer located under the animal's intradermal layer, thereby causing side effects due to the injected drug.

Therefore, the multi-needle 10 for injection of veterinary medicine according to an embodiment of the present invention includes a needle 500 having a length in the above-described range, so that it can be used in the animal and is precisely inserted into the intradermal layer of the animal. Side effects from infusion can be prevented. The length of the region dd of the needle 500 may be 1.5 mm to 5 mm, preferably 3 mm. However, it is not limited thereto.

Conventionally, in the case of short teeth used to inject a drug into an animal, it has been used to deliver the drug to muscle cells of the animal with one needle. However, in this case, a side effect occurs due to the needle inserted into the muscle cells, there was a problem that the abnormal meat occurs. In order to prevent this, a single needle was inserted into the inner layer of the animal. However, in order to insert the needle into the inner layer of the animal, it was required to accurately inoculate a fixed animal in a fixed state without moving the veterinarian or zookeeper. Uniform inoculation was not possible every time, and there was a limit that the animals were not suitable for farming as the animals moved.

On the other hand, the veterinary medicine injection multi-needle 10 of the present invention includes a plurality of needles 500, when one first needle is inserted into the animal's intradermal layer, the other second needle is also inserted at the same time I can support it. That is, the veterinary medicine injection multi-needle 10 may reduce the inoculation error range by uniformly delivering a predetermined drug to the intradermal layer of the animal through the plurality of needles (500). In addition, the multi-needle 10 for injection of a veterinary medicine has a relatively large target area into which a drug is injected, compared to a single needle, and the second needle 500 may be inserted even if one of the first needles 500 is incorrectly inserted into the target position. May be injected into a desired target point, such as the intradermal layer, thereby improving the inoculation efficiency.

That is, unlike the single needle, the multi-needle 10 for veterinary medicine injection of the present invention accurately corrects a uniform amount of drug every time the user is authorized to inject drugs such as veterinary medicine, for example, a zookeeper or a veterinarian. It has the effect of injecting in place.

In addition, the veterinary medicine injection multi-needle 10 can be used in large animals such as cows or pigs having a thick skin, including the needle 500 having a relatively large diameter and length, by the fixing part 300 The fixed needle 500 may be prevented from being bent or damaged. Accordingly, the multi-needle 10 for injection of a veterinary medicine has an effect of preventing side effects caused by a single needle while simultaneously expressing the same efficacy of the drug.

Meanwhile, the multi-needle 10 for veterinary medicine injection according to an embodiment partially covers the cap 450 and the needle 500 exposed from the housing 100, and a cover 900 fastened to the housing 100. It may further include. The cover 900 may perform a function of protecting the cap 450 and the needle 500 exposed from the housing 100 and providing a safety to a person in handling. However, the present invention is not limited thereto, and in some cases, the cover 900 may be omitted.

The shape of the cover 900 may be substantially the same as the housing 100. The housing 100 may have the same shape as the outer wall 120 of the housing 100 so as to cover the exposed portions of the housing, for example, the cap 450 and the needle 500. In the drawing, the outer wall is formed so that the cover 900 has a predetermined height from one surface having a rectangular shape in cross section, and the outer wall is formed with a fastening portion fastened to the housing 100. However, the present invention is not limited thereto.

That is, the second outlet 252, the first through hole 310, and the second through hole 410 also have different outlets (or through holes) at equal intervals based on one outlet (or through hole) positioned in the center. It may be spaced apart.

In this case, nine or eight second injection holes 251 of the support part 200 may be formed according to the arrangement of the needle 500 in the same manner as the second discharge holes 252. However, the present invention is not limited thereto, and as described above, only one second injection hole 251 may be disposed at the central portion of one side of the support part 200. Accordingly, the second injection passage 253 of the support 200 may be formed to connect one second injection hole 251 and the plurality of second discharge holes 252. As described above, since the plurality of second outlets 252 are spaced at equal intervals based on one second outlet 252, the second injection passages 253 may have the same length, respectively.
