Description
Technical Field
The invention relates to a skin test needle, in particular to a painless skin test needle.
Background
Skin test is short for skin or intradermal sensitivity experiment, allergic reaction such as penicillin, chain toxin, cytochrome C and the like is easy to occur in clinical use of certain medicines, common allergic reaction comprises rash, dermatitis, fever, anaphylactic shock and other symptoms, when a patient needs infusion treatment, the patient needs to pass through the detection of the skin test, and then the condition of the patient after the skin test is checked for treatment, and the skin test needle is one of the simplest skin test equipment.
The most commonly used part of the skin test is the curved side of the forearm, so the skin is smooth and fine, and the test operation and the result observation are convenient. One side of the left and right arms was tested and the other side was compared according to the normal practice. The upper arm or back skin may also be used if desired. The specific test methods can be classified into intradermal test, prick test and patch test.
Intradermal test: the test antigen and the control solution were injected into the skin (not subcutaneously) with a skin test needle at 0.02 to 0.03ml each, and a circular hillock was locally formed. When multiple antigens are tested simultaneously, they are spaced at least 4cm apart from each other so as not to obscure the results when they are strongly reacted. The sensitivity of the intradermal test is higher than that of other skin tests, and the antigen used should be diluted appropriately so as not to cause serious reaction; when the highly suspicious antigen has a negative result, the antigen concentration should be gradually increased for repeated tests. The intradermal test is the most commonly used skin test, and has a wide range of applications, and almost all types of antigens and reactions can be measured by the intradermal test, except for the time for observation of the different types of reactions and the criteria for determination of the results.
Picking and piercing test: also known as a stab test or a stab test. Respectively dripping test antigen and control liquid on the skin of a test part, and penetrating the liquid drop by a needle point or gently pricking the skin so as to puncture the skin but not bleed; after 1min the antigen-free solution was swabbed (sucked). When multiple antigens are tested simultaneously, the millions of people pay attention not to mix different antigen liquids in a cross way so as to avoid false positives. The prick test is mainly used for treating the allergic reaction, and although the sensitivity of the test is slightly lower than that of the intradermal test, the test has fewer false positives and stronger correlation with clinic and other tests. The scarification test (scratch test) is a variation of the prick test, in which one or more scars of about 1cm in length are made in the skin with a three-edged needle or syringe needle. It is not commonly used because the size and the length of the scratch are difficult to grasp.
Patch test: a method of applying the test antigen directly to the skin surface. When the test antigen is ointment, the test antigen can be directly smeared on the skin; if solid, the composition can be mixed with distilled water or soaked and then applied to skin; if the gauze is soaked in water solution, the gauze is applied to skin. The antigen concentration is preferably in the range of 0.5 to 1cm, based on the principle of not irritating the skin. Covering with oiled paper or cellophane after coating, and fixing with gauze or bandage; the user can open the device to view at any time if the user has obvious discomfort and can perform proper treatment. The patch test mainly detects type IV allergy, the sensitivity degree is not too high, but false positives are fewer, and the reliability of results is high.
