Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of skin pricking devices, in particular to an allergen skin pricking device for allergy department. Background Art
[0002] The "allergy" in the allergy department refers to the loss of normal immune mechanism. The allergy department specializes in treating allergic diseases of the respiratory system, skin, five sense organs, cardiovascular system, digestive system and other organs. The skin prick test is currently the most commonly used allergen diagnosis method in clinical practice. The specific operation of the skin prick test is: the patient takes a seat, relaxes his arms and places them on the table, disinfects the skin on the flexor side of the forearm of the subject with alcohol, and then drips the positive control solution, negative control solution, and various allergen extracts on the disinfected flexor side of the forearm in turn. A certain distance is left between each two drops to prevent the reaction blush from merging with each other, and then the puncture needle is used to gently pierce the surface of the skin. After a period of time, the residual liquid on the skin is wiped off with a cotton swab, and the experimental results are observed. The intensity of the patient's reaction to the allergen is determined by comparing the size of the wheal of the allergen and the positive control, and finally the patient's allergen is determined.
[0003] As can be seen from the above, the process of allergen skin pricking is to first disinfect and mark, then drip the positive control solution, negative control solution, and various allergen extracts on the disinfected forearm flexor skin in turn, and then gently pierce the skin surface with a pricking needle. Therefore, dripping and pricking are two processes, so the nurse needs to first take the drip tool, then put down the drip tool, and then take the pricking tool. Therefore, this step requires taking and putting the tool multiple times, which results in a long time and low detection efficiency. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides an allergen skin pricking device for allergy department.
