Abstract
The invention discloses a convenient-type transdermal administration patch apparatus and a preparation method thereof. The patch apparatus comprises two units, a communications control device and an administration device, the administration device is fixedly arranged on the lower end section of the communications control device, the communications control device and the administration device make an electrical connection, the communications control device comprises mini cells and a wireless control device and a microcontroller a, the mini cells, the wireless control device and the micro-controller a make electrical connections; after the starting procedures of preparation of drug involved patches, preparation of non-drug involved patches, electrode fixing, docking with a microcontroller b, docking with the communications control system and dosing, the preparation of the convenient-type transdermal administration patch apparatus is fulfilled. The transdermal administration apparatus is wearable and remote-controllable, the dose administration is convenient, and is particularly suitable for the conditions of daily medications for elderly patient with chronic illness and plenty of admitted inpatients: the dose time and amount are pre-arranged by the nursing crew according to the prescription requirements of the doctors, patient medication at fixed time and fixed amount is complied with, and the time and energy of the medical staff are saved.
Description
technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a convenient transdermal drug delivery patch device and a preparation method thereof. Background technique [0002] Most drugs are currently administered orally or by injection. Oral administration is in the form of tablets, capsules, liquids, etc. However, due to the absorption of the drug in the gastrointestinal tract and the first-pass effect in the liver, many oral drugs reduce the bioavailability of the drug before reaching the site of action, and often bring come side effects. There are also some drugs that cannot be administered orally, such as: peptides and protein-related drugs. Another common mode of administration is injection, which enables drugs to penetrate biological barriers, including subcutaneous injections and intravenous injections. Although this method is fast and effective, the injection can cause additional pain for the patient, cau...
