Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a needle for acupuncture treatment for infertility in sows, and in particular to an external shape of the tip of the needle to increase the effect of acupuncture treatment.

Conventionally, since acupuncture treatment was generally only performed on people, the tip of the needle bar for acupuncture treatment was formed into an elongated conical shape with a pointed tip, and the needle bar was designed to touch the skin. However, when this needle bar is inserted into a pot that can promote estrus in a non-estrous sow that is capable of becoming pregnant, such as Hyakhui or Kaifu, there is almost no sign of estrus promotion. There was a drawback.

An object of the present invention is to eliminate the above-mentioned drawbacks of the conventional art by providing a needle bar for acupuncture treatment that can sufficiently enhance the effect of promoting estrus.

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

Diameter d=1.5~3.0mm, effective length l=60~150mm,
In this example, the stainless steel needle bar 1 with a diameter d = 2.5 mm and an effective length l = 112 mm can apply a compressive force in the direction of needle bar 1 insertion to the sow with its tip when the needle bar 1 is inserted. The leading edge of the semicircular shape 2 is sharpened at a substantially right angle so that it can be pierced with a strong pushing or driving force from an external force, and
A head 3 with a flat end face is attached to the rear end of the needle bar 1 so that the needle bar 1 can be easily inserted by pressing with the palm of the hand or by hammering. A knurling 4 with an uneven surface is formed to prevent slipping so that the rear needle bar 1 can be easily turned left and right with fingers.

The needle bar 1 formed in this way, in this embodiment, has a substantially circular tip 2 as shown in FIGS. 1 and 2.
The formed needle bar 1 is used as a sow 7, and in this case, even if all kinds of treatments to promote estrus, especially by applying hormones, the treatment is ineffective, and the pig is anestrus 68, which is about to be abandoned.
As a result of acupuncture treatment on the head as shown in FIG. 3 using the needle bar 1 of this example, the following favorable results were obtained.

First, the holes to be inserted with the needle bar 1 are determined in advance at Hyakue and Kaifu by referring to changes in the external shape, movements, sounds, etc. of the pig caused by external acupressure. As a result of acupuncture treatment, the percentages of estrus, slight estrus, and no estrus among 68 anoestrus pigs just before slaughter were as follows: 57 pigs in heat, 83.8%, 3 pigs in mild heat, 4.4%, and 8 pigs in heat, 11.8%. Of the 57 pigs in heat, 2 refused to mate, so the number of pigs inseminated was 55, and the success rate of insemination was 55 out of 68.
The figure is extremely high at 80.9%.

Note that the degree of estrus caused by acupuncture varies to some extent depending on whether sow 7 is a nulliparous pig or a multiparous sow, but as the majority of pigs are in estrus as a whole, it remains to be determined. Data such as degree of estrus and number of days to induce estrus by parity, including parity, are omitted.

FIG. 4 shows a needle bar 8 according to another embodiment of the present invention. In this case, a mark 10 for confirming the rotation angle of the needle bar 8 is provided on the head 9. The effect is also the same as that of the above embodiment.

Next, the effects of the present invention will be explained.

The first invention is to provide a metal needle bar with a tip shape that can be inserted almost perpendicularly into the pig's outer skin to any desired depth for acupuncture treatment, and to insert the tip into the pig in the needle bar insertion direction when the needle bar is inserted into the pig. The needle bar for acupuncture treatment is formed into a substantially semicircular shape capable of applying a compressive force, and has a tip end thereof sharpened at a substantially right angle so that it can be inserted with a strong pushing or driving force by an external force.

As described above, by performing acupuncture treatment using the formed needle bar, the present invention has the effect of being able to perform acupuncture treatment that is sufficiently effective in promoting estrus even for anoestrous pigs that are about to be abandoned.

Next, the second invention is to insert a metal needle bar into the pig with the tip shaped so that it can be inserted into the pig's outer skin at an arbitrary depth to achieve acupuncture effect at a substantially right angle. The needle bar is formed into a substantially semicircular shape that can apply a compressive force in the insertion direction, and the tip of the needle bar is sharpened at an approximately right angle that can be inserted with a strong pushing or driving force by an external force. A head for receiving external force when the needle bar is inserted is formed at the rear end of the rod, and an uneven knurling is formed on the outer periphery of the head to facilitate rotation of the needle bar by external force after the needle is inserted. This needle bar for acupuncture therapy has a mark formed on the outer periphery of the head terminal to confirm the rotation angle of the needle bar.

As a result, the present invention has the effect of obtaining the effect of the first invention, and further has the effect of making it easier to operate the needle bar during acupuncture treatment and making the effect of acupuncture treatment even more pronounced.
