As we all know the advantages and curative effects of Penicillin,streptomycin and cephalosporin and so on , but traditional intradermal injection has been subject to quality of instruments, cooperation of patients(especially children), skill level and mood of manipulators and so on. Moreover, the randomicity is quite strong. The injection of test solution can cause traumas to skin tissue and then engender certain effluence towards allergic reaction that the reactive symptoms will change consequently. Furthermore, once the injection is finished, the liquid can not been taken out and this remains a hazard to hypersensitive patients.

Our QY-1A drug anaphylaxis skin tester is a new product with breakthrough concept of painless injection. Therefore, it has solved various problems caused by the needle-stab skin test. The instrument has the following features:

1. Neither any impairments to tissues, nor sense of pain during skin test;

2. Monitor control and malfunction-reorganization alarm system set in the whole process of skin test have insured the precision and reliability of skin test.

3. Largely shorten reaction time

4. If a patient is hypersensitive, power can been turned off at any moment to stop the infiltration and thus ensure patients' safety.

5.A big change from conventional skin test method manipulated by hand and with scientific standard operations.
