Description

Detailed Description of the Invention

[0001]

The present invention relates to an intradermal needle and an intradermal needle set for acupuncture and moxibustion.

[0002]

[Prior art]

(1) Form of Intradermal Needle As shown in various types of conventional intradermal needles in FIGS. 8 (a) to 8 (c), a needle body 1 and a circular needle formed on the proximal end side thereof are provided. It is composed of a square or square crown 2. (2) How to puncture an intradermal needle As shown in FIG. 9, tweezers 3 sandwich 3 mm from the tip of needle body 1 of the intradermal needle, and cut the skin skin in a direction substantially parallel to skin surface 4 of the affected area. Insert about 2-3 mm into the inside (Fig. 5). Thereby, there is an advantage that the operator's hand does not touch the needle which has been sterilized in advance, and the needle is hygienic.

[0003] (3) Method of fixing the intradermal needle After confirming that the needle is securely inserted into the skin, FIG.
As shown in, a small adhesive bandage 6 is applied under the crown 2 of the intradermal needle so as to make a pillow, and then a large adhesive bandage 7 is applied over the entire intradermal needle. By this, in the treatment with the calligraphy, the action of the needle is only during the treatment,
Since the puncture can be continued for a long time by fixing the intradermal needle, there is an advantage that the therapeutic effect is maintained during the puncture period.

[0004]

However, in such a conventional general intracutaneous needle, since the needle is sandwiched by the tweezers 3, the positioning is unstable, the adjustment becomes complicated, and the needle is punctured. Even during insertion, depending on the position of the tweezers 3 and the timing of the procedure, there were problems such as needle bending and defective needle insertion.

Further, since the crown 2 of the intradermal needle is small, if the crown is fixed as it is, irritation occurs on the skin, so that it is necessary to apply a small adhesive plaster 6 underneath. Furthermore, since two adhesive plasters are used together with the large adhesive plaster 7 for fixing on the top, the work becomes complicated and there is a problem that the skin breathing is disturbed. In addition, since plasters are purchased and used for general purposes, they are uneconomical, and some of them do not fit in shape, so that there is a problem that the intradermal needle cannot be securely fixed.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide an intradermal needle that can be easily punctured and fixed, and further provide an intradermal needle set combined with a special adhesive bandage.

[0007]

Therefore, the present invention provides an intracutaneous needle in which a wing-shaped crown is provided on the proximal end side of the needle body. Here, the crown of the airfoil is made of a flexible material,
The needle body may be held by insert molding.

Further, it is preferable to form irregularities on the skin contact surface of the wing-shaped crown. Furthermore, it is advisable to store the above-mentioned intradermal needle and a larger bandage one by one in a container to form a set.

[0009]

In the above-mentioned intradermal needle, since a wing-shaped crown is provided at the base end side of the needle body, the wing-shaped crown can be pinched with a fingertip, and the needle can be stuck. Is assured. Also, since the crown is large and can be brought into surface contact with the skin surface, it does not cause irritation to the skin,
Eliminates the need to paste a small bandage.

Here, by molding the wing-shaped crown with a flexible material, no bluntness or discomfort is provided at the contact portion, and irritation is further reduced. Further, by forming irregularities on the skin-contacting surface of the wing-shaped crown, it becomes easier to adapt to the skin and it does not hinder the skin breathing.
Furthermore, by storing the above-mentioned intradermal needle and a larger bandage one by one in a container to form a set, there is no need to separately facilitate a general-purpose bandage, and it is economical and the size is suitable. Is secure.

[0011]

Embodiments of the present invention will be described below. Figure 1 (a)
~ (C) shows the form of an intradermal needle as one embodiment of the present invention,
If (b) is a front view, (a) is a left side view and (c) is a right side view. The intradermal needle includes a needle body 11 and a wing-shaped crown (hereinafter referred to as “wing”) 12 formed at a base end side of the needle body so as to be pinched by a fingertip so that the needle can be inserted. Here, the wing 12 is formed of a flexible material, specifically, a soft resin (for example, a polyolefin-based elastomer or polypropylene) or rubber, and the needle body 11 is held by insert molding.

The wing 12 shown in FIG. 1 is a wing type,
The needle body 11 extends obliquely rearward from the cylindrical portion 12a that covers the proximal end side of the needle body 11. However, the base of the wing 12 is eccentric from the center (needle body 11) of the cylindrical portion 12a, so that when one surface (skin contact surface) 12b of the wing 12 is brought into contact with the skin surface, the cylindrical portion 12a Are not in contact with the skin surface.

The skin contact surface 12b of the wing 12 is formed with a plurality of grooves extending parallel to the direction in which the needle 11 extends, thereby forming an uneven surface. The form of the wing 12 is not limited to the example shown in FIG. 1, and various forms can be employed as shown in FIGS. 2 (a) to 2 (i). That is, the direction in which the wings 12 extend may be diagonally forward (d to g) or may be a right angle direction (h, i).

Further, a pair of left and right wings 12 may be provided to form a double wing (a, b, d, f, h). In the case of the double-wing type, it is preferable that the wings are formed in asymmetrical shape, in particular, the wings have different lengths. FIGS. 2 (a) to 2 (i) show only the state where the wing is viewed from the side opposite to the skin contact surface, but the skin contact surface on the back side is formed as an uneven surface as shown in FIG. is there.

It should be noted that FIG. 3 shows that of FIG.
FIG. 3A shows the form of the intradermal needle viewed from three directions as in FIG. 1. FIG. 3B is a front view, FIG.
FIG. 3C is a right side view. FIG. 4 shows an embodiment of the intradermal needle set according to the present invention. In this intradermal needle set, an intradermal needle (needle body 1 and wing 12) and a slightly larger oval bandage 13 are stored in a container one by one.

The storage container comprises a case 14 made of a resin film and a sterile gas-permeable sealing paper 15 as a lid member. The case 14 is formed by drawing on an oval film to form an oval stepped portion 14b while leaving a flange portion 14a. Further, a groove 14c for accommodating an intradermal needle is formed at the bottom of the stepped portion 14b.
Is formed.

Here, the groove 14 at the bottom of the case 14 is used.
c, the intradermal needle (needle body 11 and wing 12) is housed, and the exclusive bandage 13 is housed by being locked to the step 14b thereon. After storage, the sterilizing gas-permeable sealing paper 15 is heat-sealed to the flange portion 14a of the case 14. The seal paper 15 is peeled off from the case 14 before use. In this case, a so-called peel tab is formed so that a part of the seal paper 15 protrudes from the flange portion 14a so that it can be easily picked with a finger.

After heat sealing, gas sterilization is carried out by an ordinary method using an ethylene oxide gas or the like. Although FIG. 4 shows one having a single-wing wing, it can be set similarly to one having a two-wing wing. Next, a method of piercing the intradermal needle with a wing according to the present invention will be described.

As shown in FIG. 5, the wing 12 is pinched with a fingertip, and as shown in FIG. 6, the wing 12 is inserted into the skin by a distance of about 2 to 3 mm in a direction substantially parallel to the skin surface 16 of the affected area (see FIG. 17). ). Here, if you have a single wing type wing 12, after insertion
Rotate 90 ° to make skin contact surface 12b of wing 12 skin surface
Make it parallel to 16. When the wing 12 has a double wing shape, the wing 12 has flexibility, so that the wing 12 is pinched so as to grasp a butterfly wing. When the finger is released after insertion, the wing 12 becomes parallel to the skin surface 16 by its own elastic restoring force.

In this manner, the wing 12 can be pinched by pinching the wing 12 with a fingertip, so that positioning is easy and the needle is reliably inserted. Next, a method for fixing the winged intradermal needle according to the present invention will be described. After confirming that the needle is surely inserted into the skin, as shown in FIG. 6, the needle is fixed only by sticking on the top with a dedicated bandage 13 set. Wing 12
This is because the skin comes into surface contact with the skin surface 16 so that the skin is less likely to be irritated, and there is no need to apply a small adhesive plaster under the skin.

Further, since the wing 12 is formed of a flexible material, the contact portion does not give a feeling of bluntness or discomfort, and the irritation is further reduced. Also, since the skin contact surface 12b of the wing 12 has an uneven surface, it is easily adapted to the skin and does not hinder skin respiration. In addition, because it is set with a dedicated adhesive plaster 13 that is sized to match the shape of the winged intradermal needle, it is not necessary to separately prepare a general-purpose adhesive plaster, it is economical and the size is suitable. Therefore, it is securely fixed, and it is easy to remove it when removing the needle.

In this way, needle positioning, puncture, fixation,
The object of improving the ease of use of the needle can be realized with a minimum number of parts and without impairing the advantages of the conventional intradermal needle. Of the various forms of the wing 12 shown in FIG. 2, the wings (a, b, d, f, h) of the double-wing type are left-right asymmetric and have different wing lengths. The reason for doing so will be explained.

As shown in FIG. 7 (a), when the length of the left and right wings 12 is the same in the double-wing type, when the butterfly is grasped, the portion of the cylindrical portion 12a covering the needle body 11 is formed. Will be bent. In order to make it easy to bend, a bend 18 is provided at the portion to be bent to make the wall thinner. However, since the needle body 11 needs to be covered, there is a limit to the reduction of the wall thickness, and it is difficult to bend. Further, the fact that it is difficult to bend means that the position of the needle body 11 in the bent state is not stable, and the positioning is not easy.
Further, since the cylindrical portion 12a comes to the lowermost position, the cylindrical portion 12a comes into contact with the skin at the time of pricking, so that the needle body 11 is easily moved, which also makes positioning difficult.

In view of the above, as shown in FIG. 7 (b), when the lengths of the left and right wings 12 are made different and the ends of the left and right wings 12 are pinched together, the cylindrical portion 12
so that it can be bent at the part outside of a. Therefore, by forming the wall recess 18 in the bendable portion to make it thinner, the bending becomes easier and the bent state becomes stable. Furthermore,
Even when the cylindrical portion 12a is hidden inside when the needle is punctured and the lowermost part touches the skin, the needle body 11 is less likely to move, and therefore the needle body 11 has good stability during the puncture. Therefore, positioning becomes easy.

[0025]

As described above, according to the present invention, since the wing is provided on the base end side of the needle body, the wing can be pinched and pinched by a fingertip, positioning is easy, and the puncture is easy. The effect of being certain is obtained. Moreover,
Since the wing can be brought into surface contact with the skin surface, there is little irritation to the skin, and there is no need to apply a small adhesive plaster underneath, which also has the effect of facilitating fixation.

Further, by forming the wing with a flexible material, the contact portion does not feel blunt or discomfort, and irritation is further reduced. Further, by forming the unevenness on the skin contact surface of the wing, it becomes easy to fit into the skin and does not hinder the respiration of the skin. Furthermore,
By storing the winged intradermal needle and the dedicated adhesive plaster one by one in a container, there is no need to separately prepare a general-purpose adhesive plaster, it is economical and the size is fixed, so it is fixed Will be certain.
