Soluble anesthetic microneedle

Abstract

The invention discloses a soluble anesthetic microneedle. The microneedle comprises an outer cladding layer and effective ingredients, wherein the effective ingredients comprise, in parts by weight, 13-18 parts of flos daturae, 6-13 parts of radix aconiti, 5-10 parts of rhizoma chuanxiong, 4-8 parts of tabasheer, 4-8 parts of herba asari, 5-12 parts of radix zanthoxyli, 10-16 parts of herba menthae, 3-6 parts of toad venom, 8-14 parts of radix notoginseng, 4-7 parts of radix angelicae sinensis, 4-8 parts of flos lonicerae, 3-7 parts of ephedrine, 1-3 parts of cortex albiziae and 4-9 parts of radix angelicae. The soluble anesthetic microneedle has the advantages as follows: various anesthetics are highly selected and combined optimally on the basis that the anesthetic effect is guaranteed,so that the dosage and toxic and side effects of each medicine are reduced, the safe range and the use range of the soluble anesthetic microneedle are enlarged, and the best anesthetic technique is provided under the condition of minimum interference to physiological activities of bodies; postoperative bleeding can be reduced and infection can be prevented; the soluble anesthetic microneedle is biodegradable, can be completely dissolved or degraded to release inside effective ingredients and has a certain slow release effect.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine and pharmacy, and in particular relates to a soluble anesthetic microneedle. Background technique [0002] Anesthesia is a variety of methods used to eliminate pain, ensure patient safety, and create good surgical conditions during operations or diagnostic inspections. It mainly includes three types: local anesthesia, regional anesthesia, and general anesthesia. Local anesthesia is the mildest type and numbs only a small area, such as a single tooth. Regional anesthesia is the injection of drugs into the spine to block nerve signals to the brain, thereby rendering a larger area of ​​the patient unconscious. Often, patients receiving regional anesthesia are also given a smaller dose of a strong sedative drug, such as propofol—a dose that does not render the patient completely unconscious, but enough to alter brain activity so that the patient is less aware and less responsive ...

Problems solved by technology

However, the tablet makes the body part of the anesthetized uncontrollable. In addition, the tablet needs to be absorbed by the patient to exert its effect, but each patient has individual differences in the absorption of the drug. Therefore, the dose cannot be accurately grasped. The patient has completed the operation, but the anesthetic cannot be excreted; if the dose is small, the patient can wake up during the operation, making the patient more painful, which is also a potential harm to the patient
