preparation example Construction

[0050] The preparation method of the self-heating layer includes the following steps: under the protection of vacuum and nitrogen, the components are mixed into a paste, and then the paste is added to the synthetic resin film and pressed into a single-sided (with insulating layer) The contact surface) is a sheet with micropores.

[0051] The magnetic therapy material is composed of the following raw materials by weight: 15-20 parts of magnetic powder, 15 parts of dried ginger powder, 5 parts of sodium alginate and an appropriate amount of water.

[0052] The preparation method of the magnetic therapy layer includes the following steps: mixing magnetic powder and dried ginger powder, making a paste with warm water, then adding sodium alginate and mixing, wrapping with aluminized film, and pressing into a double-sided microporous The flakes are available.

[0053] The analgesic material is composed of the following raw materials by weight: 9 parts of Chuanwu, 9 parts of Caowu, 9 parts...

Embodiment 1

[0082] Such as image 3 As shown, a painless microneedle includes a needle body 1 and a functional layer 2; the needle body 1 includes a needle handle 12 and a needle tip 13; the oval needle handle 12 is connected to the functional layer 2; the functional layer 2 It includes a self-heating layer 21 and a magnetic treatment layer 22 arranged in sequence from top to bottom. The self-heating layer 21 is made of a sheet with micropores on one side by placing a self-heating material in a synthetic resin film. The treatment layer 22 is made by placing the magnetic treatment material in an aluminized film to make a thin sheet with 1-3mm micropores on both sides; the insulation layer 3 is made of plastic film material and is arranged on the uppermost end of the functional layer, on the insulation layer The tearing end 31 is provided. Then the insulating layer, the self-heating layer and the magnetic therapy layer are connected in sequence from top to bottom, wherein the insulating lay...

Abstract

The invention discloses a painless microneedle and a preparation method thereof. The painless microneedle comprises a needle body and a functional layer, wherein the needle body comprises a needle handle and a needle tip; the needle handle is connected with the functional layer; the functional layer comprises a self-heating layer and a magnetic therapy layer or a traditional Chinese medicine layerarranged below the self-heating layer. The painless microneedle disclosed by the invention has the effects of slight anesthesia and analgesia, and does not cause pain after being used for a long time; the self-heating layer is provided with an isolation film which can be uncovered, and after the isolation film is uncovered, the self-heating layer makes contact with air to start heating; the magnetic therapy layer or the traditional Chinese medicine layer can dredge channels and collaterals, regulate qi and blood, resist inflammation and ease pain, and directly acts on an affected part by means of heating of the heating layer, and medicine efficacy permeation is better.

Description

Technical field [0001] The invention relates to the field of medical devices, in particular to a painless microneedle and a preparation method thereof. Background technique [0002] Needle-embedding therapy is a method in which special intradermal needles (microneedles) are fixed in the skin or under the skin of acupoints for a long time in traditional Chinese medicine treatment. It is also called intradermal needle therapy. Intradermal needles can give the skin The department uses weak and long-term stimulation to adjust the functions of the meridians and viscera to achieve the purpose of preventing and curing diseases. [0003] At present, the commonly used intradermal needles, on the one hand, are painful during puncture and cause physical and mental effects on pain-sensitive patients; on the other hand, the existing micro-needles only play a role in stimulating acupoints, and are not related to magnetic therapy, hyperthermia and other traditional Chinese medicine. The treatmen...
