Fast insertion gun for allergy test

Abstract

The invention relates to a fast insertion gun for an allergy test. The fast insertion gun for the allergy test comprises a handle (1), a sliding operation rod (2), a scaleplate (3), a gun body (4) and a plurality of fast insertion needles (5), wherein the scaleplate (3), the gun body (4) and the fast insertion needles (5) are connected with the sliding operation rod (2). The fast insertion gun for the allergy test is characterized in that a plurality of fast insertion needle fixing pillars (6) are fixedly arranged at the lower end of the gun body and the sliding operation rod (2), and the fast insertion needles (5) are installed on the fast insertion needle fixing pillars (6) in a sleeved mode; the handle (1) is made of stainless steel or plastics; the sliding operation rod (2) is installed on a lateral surface of the handle (1) and slides in a sliding groove way in the lateral surface of the handle. As the fast insertion gun is used, the fast insertion depth is limited, the fast insertion liquid amounts of all test points are the same, the scaleplate, corresponding to the fast insertion positions, carried by the fast insertion gun can be used for carrying out wheal size measurement after fast insertion is finished, and the fast insertion gun for the allergy test is easy and convenient to operate, high in efficiency and accurate and reliable in result.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a pricking gun for allergy testing, which is suitable for skin pricking in the initial stage of allergy testing and judgment of results in the later stage. Background technique [0002] As early as 1906, the Austrian pediatrician Clemens van Pirquet coined the term "allergy". After a century of changes, with the development of social economy and the enrichment of material life, the incidence of allergic diseases is on the rise all over the world. In 2005, the World Allergy Organization (WAO) and the World Health Organization (WHO) jointly proposed that July 8th be "World Allergy Day", which shows that allergic diseases have become a global concern. [0003] The etiology of allergic diseases is complex and diverse, and the causes of allergies also vary from time to time and from place to place. The sensitizing substances that cause allergic diseases in atopic individ...

Problems solved by technology

[0005] The existing pricking technology is limited by pricking equipment, and there are three major problems in practical application. These three problems have always been the troubles faced in allergy testing

[0006] Problem 1: The environment of the sick individual is complicated, and there are often many allergens that need to be screened. It is time-consuming and labor-intensive to perform the prick test one by one, and the time between the first and the last prick is too long;

[0007] Difficulty 2: When the medical personnel use the pricking needle to puncture the skin for a single time, since the puncture strength and puncture time of each test point cannot be guaranteed to be exactly the same, the puncture depth cannot be completely consistent, so the test allergen stock solution enters each part of the skin. The dose at the test point may not be consistent;

[0008] Problem 3: The dosage of the test solution at each test point is not uniform with each other, and the time from the observation result after the point pricking is inconsistent, which leads to the fact that the later measurement cannot fully reflect the real situation
