The second fixing portion 42 may be formed in any one of a hemispherical shape, a spherical crown shape, a semi-ellipsoidal shape, a front hemispherical cylindrical shape, and a front spherical crown cylindrical shape, and when the second fixing portion 42 is formed in the above structure, a massage effect on the acupuncture point after the intradermal needle is embedded in the acupuncture point is good.
The projected area of the first fixing portion 41 on the adhesive member 2 may be larger than the projected area of the second fixing portion 42 on the adhesive member 2, so that the intradermal needle receives and transmits the pressure of the compression when the intradermal needle is embedded in the acupoint. The diameter of the needle head 12 of the intradermal needle body 1 may be 0.16mm to 0.25mm, and the outer diameter or the maximum size of the first fixing portion 41 may be 3.0mm to 3.5mm, preferably 3.2 mm. The outer diameter or the maximum dimension of the second fixing portion 42 may be 1.5mm to 2mm, and preferably 1.7 mm. The first fixing portion 41 and the second fixing portion 42 having the above dimensions have a good fixing effect on the intradermal needle, and are convenient to press when the needle is buried.
The off-shaped part 3 is provided with a through hole, the first fixing part 41 is fixedly connected with the second fixing part 42 through the through hole of the viscous part 2 and the through hole of the off-shaped part 3, namely, the first fixing part 41 and the second fixing part 42 can be integrally injection-molded and can also be fixed by threads.
The intradermal needle body 1 penetrates through or is close to the central axis of the first fixing part 41, which is perpendicular to the surface of the adhesive member 2, so that the pressing force applied to the intradermal needle in the process of embedding the needle is more uniform. And/or the intradermal needle body 1 passes through or is close to the central axis of the second fixing part 42, which is perpendicular to the surface of the viscous member 2, and when the intradermal needle is pressed through the first fixing part 41, the supporting force of the second fixing part 42 on the needle head 12 of the intradermal needle body 1 is more balanced.
In particular, the separate piece 3 may be provided with a circular, oval or square through hole, through which the first fixing portion 41 passes through the separate piece 3. Preferably, the shape of the through hole is matched with the shape of the fixing part of the first fixing part 41 and the adhesive member 2, and the separate member 3 can better prevent pollution.
Specifically, the needle handle 11 may be any one of a T-shape, an inverted L-shape and a ring shape, and the needle handle 11 with the above shape may be better combined with the first fixing portion 41, so as to improve the fixing strength of the first fixing portion 41 to the needle handle 11; the needle handle 11 and the needle head 12 can be integrally formed, and the strength and the toughness of the integrally formed intradermal needle body are better. Or, the needle handle 11 and the needle 12 can be two independent parts which are assembled and connected, and the needle 12 or the needle handle 11 can be replaced by a spare needle 12 or the needle handle 11 after a problem occurs in the needle 12 or the needle handle 11, so that the cost is saved.
The needle 12 passes through the through hole of the adhesive member 2 and the release member 3 and extends in a direction away from the adhesive member 2, and is perpendicular to the combining surface of the first fixing portion 41 and the adhesive member 2. When in use, the first fixing part 41 is pressed by external force, and the hypodermic needle is stressed evenly and is not easy to bend.
Specifically, the adhesive member 2 of the intradermal needle is further provided with a bearing layer for bearing the adhesive layer, wherein the bearing layer is any one of non-woven fabric, elastic fabric, polyester cotton fabric and chemical fiber fabric; the adhesive layer of the adhesive part 2 is a water-soluble pressure-sensitive adhesive layer, so that glue cannot be left on the skin after the intradermal needle is used; the release piece 3 is release paper or release film, and plays a role in isolating the adhesive layer of the adhesive piece 2.
Specifically, a plurality of intradermal needle bodies may be disposed on the adhesive member 2 of the intradermal needle, and each of the intradermal needle bodies may be correspondingly matched with the individual first and second fixing portions 41 and 42. Every intradermal needle body interval certain distance that sets up, single intradermal needle corresponds solitary acupuncture point when using, and a plurality of intradermal needles can correspond a plurality of acupuncture points to reach the effect of massaging a plurality of acupuncture points simultaneously.
