A non-invasive painless rapid allergy skin tester

Abstract

The invention discloses a non-invasive painless rapid allergy skin tester, and relates to the field of medical devices. The tester is characterized in that the tester includes a host computer; the host computer is provided with an ionization component for promoting drug penetration, the ionization module comprises a PCB board and a single chip microcomputer MCU arranged on the PCB board; the inputend of the single chip microcomputer MCU is provided with a power supply module, a counting module and a sensor module; the power supply module, the counting module and the sensor module are electrically connected with the input end of the single chip microcomputer MCU. The output end of the single chip microcomputer MCU is provided with an alarm device. The host computer is provided with a wiring terminal electrically connected with the MCU of the single chip microcomputer, and the wiring terminal is detachably connected with a main wire, wherein the main wire comprises a positive electrodeline and a negative electrode line which are separated from each other, and the ends of the positive electrode line and the negative electrode line are provided with a connecting device; The connecting device is provided with a disposable adhesive consumable material and a sensor module for monitoring the disengagement of the consumable material, which has the advantages of safety, sanitation, convenient operation, high efficiency ionization and accurate results.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a non-invasive and painless rapid allergy skin tester. Background technique [0002] As the variety of drugs increases, different patients will have different adaptability to drugs, which will correspondingly increase the probability of patients' allergies to drugs. Therefore, some drugs need to be tested for allergies before use. At present, the methods of allergy testing include intradermal injection, scratch method, eye drop method, and iontophoresis percutaneous penetration method. [0003] The traditional intradermal injection skin test is more painful, and there are common shortcomings similar to several allergy test methods: one is more painful; Large, due to the proficiency of medical personnel, it may cause false negatives and false positives, which directly affect the life safety of patients. It takes about 20 minutes to observe, which is not easy to accept, and it is e...

However, the electrode plate is placed on the wrist, and the test agent is infiltrated into the skin by the ion infiltration method, and the negative and positive results of the penicillin allergic reaction can be detected in a relatively short period of time, but there are two electrodes in the above-mentioned skin test instrument. The skin falls off, and the electrode and the skin tester are integrated. For patients with skin diseases and normal patients, a drug-conducting electrode is shared, which is not hygienic, and the dosage of each drug is not easy to control, which affects the use effect.
