Embodiment Construction

[0011] See also shown in Fig. 1, be the first embodiment of the present invention, be that the anesthesia drug latex layer 2 is covered under the bottom surface layer 1, and the self-heating layer 3 is covered on the bottom surface layer 1, and this self-heating layer 3 is made of heating material Iron oxide (FeO) particles and water are composed in a certain proportion. When iron oxide (FeO) particles contact with oxygen in the air, a chemical reaction occurs and heat is released, resulting in a constant temperature not exceeding 50°C. The self-heating layer 3 covers Establish the surface layer 4, in this embodiment, the surface layer 4 is a breathable surface layer, the periphery of the surface layer 4 is sealed together with the periphery of the bottom surface layer 1, and the bottom surface of the bottom surface layer 1 and the periphery of the anesthetic drug latex layer 2 are coated Adhesive layer 5 is arranged, and the surface of this adhesive layer 5 and the surface of ...

Abstract

The invention discloses a heat-sensitive surface anesthesia patch and is characterized in that a emulsion layer which is anesthesia is arranged under a bottom layer and a spontaneous heat layer on the bottom layer and arranged under a surface layer, the periphery of which is sealed tighter with that of the bottom layer; wherein, the emulsion layer which is anesthesia contains anesthetics and emulsified mixture of non-active substance; the anesthetics is the emulsified mixture of oil-phase lidocaine with 75mg and teracainum with 75mg; the heat generated from the spontaneous heat layer is no higher than 50 DEG C is conducted constantly and the temperature on skin surface is elevated by 15 DEG C; with the assistant force of the heat conduction, the percutaneous force and the releasing speed of the lidocaine and the teracainum reaching subcutaneous layer and cortical layer are increased, and furtherly, the anesthesia speed of part of subcutaneous layer is also increased. With lidocaine and teracainum accumulated on the pain receptor of cortical layer and nerve endings, the ion channel which is needed when nerve impulse is generated and conducted is blocked, thereby having an anesthesia function to a body part.

Description

technical field [0001] The invention relates to a medical anesthetic, in particular to a heat-sensitive surface anesthesia patch. Background technique [0002] The idea of ​​applying local anesthetics to the skin to make percutaneous puncture injections and even minor operations painless has been proposed more than 30 years ago. In recent years, latex agents or patches for skin surface anesthesia have been approved for clinical use and have shown broad application prospects. However, there are still shortcomings such as too long application time, that is, long anesthesia time, and inconvenient use. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the latex agent or patch for skin surface anesthesia has too long anesthesia time and loses clinical significance, and provides a heat-sensitive surface anesthesia patch that can overcome the above-mentioned shortcomings. [0004] In the present invention, an anesthetic latex l...
