Description

Point thorn reading instrument Technical Field The utility model relates to equipment for skin prick test, in particular to a prick reader. Background The skin prick test (SKIN PRICK TEST, SPT), also known as a needle stick test or an intradermal test, is a method for detecting the sensitivity of the human body to a specific allergen. The test observes whether local allergic reactions are triggered by gently penetrating a prick fluid containing a trace allergen extract on the skin (usually the inner side of the forearm). The principle behind this test is that if a subject is allergic to a substance to which the immune system will produce specific IgE antibodies, these antibodies, when contacted again, trigger mast cells and basophils to release inflammatory mediators such as histamine, thereby forming a wheal (i.e. localized redness, swelling) and/or a halation at the site of the prick. The pricking liquid is a solution containing a trace allergen extract and is commonly used in skin pricking tests. These extracts are carefully prepared to ensure safety and accuracy. Each of the spotting fluids is directed against one or a specific class of allergens, such as a specific pollen species, food ingredients or insect venom. In performing the test, the healthcare worker gently pierces the surface layer of the skin using a dedicated point needle or fine needle, and then drops the point needle at the piercing site to penetrate the skin. Cellulite is a typical manifestation of allergic reactions in skin prick tests, which refers to the local edema damage caused by transient inflammatory hyperemia of the skin mucosa angiogenesis and massive fluid exudation by allergen stimulation, resulting in local swelling and redness. The size and shape of the wind mass varies depending on individual differences, allergen types and degrees of allergy. The presence of wind clusters indicates that the subject is allergic to the corresponding allergen. The measurement (e.g., diameter) of the wind mass is an important basis for assessing the intensity of the allergic reaction and for judging whether the test result is negative or positive. The skin prick test (SKIN PRICK TEST, SPT) has become the most commonly used allergen detection method in clinic because of simplicity, convenience, rapidness, sensitivity and low price. The traditional skin prick test result interpretation mode is that an acquisition personnel uses a marker pen to trace the outline of the wind mass, uses a transparent adhesive tape to transfer the wind mass to a special report paper for the prick test, and uses a measuring ruler to measure the wind mass. And judging negative and positive according to the wind cluster measurement result. Although the skin prick test is relatively quick and simple to operate, because of the continuous increase of variety of clinically used prick liquid, the collection personnel need to measure the wind mass generated by each prick liquid in sequence, which can take longer time, has strong subjectivity and has difference in individual experience and judgment accuracy.
