Description

A kind of asthma anaphylactogen Histamine positive device

Technical field

The utility model relates to technical field of medical equipment, specially a kind of asthma anaphylactogen Histamine positive device.

Background technique

Skin prick test be medical field recognized by most convenient, economy, safely, effectively, be also at present clinically most often Allergen diagnosis method, skin prick test are carried out at the forearm palmar skin position of patient, concrete operations process Are as follows: firstly, allergic effect stock reagent, negative controls and positive control solution are respectively dripped one from top to bottom after conventional transdermal disinfection It drips on the skin after cleaning, the distance between two drops are 3-5cm；Secondly, under patient skin tight state, by puncture needle Through drop, it is vertically pierced into skin；Finally, 10-20 minutes observation test results after pricking method, right by comparing allergen and the positive According to wheal size determine that patient to allergen response intensity, when carrying out the treatment of asthma, needs to carry out patient The determination of quick original needs to carry out Histamine positive When being determined, then can be in 15 minutes if patient is to the anaphylactogen allergy There is the red and swollen block of similar bite by mosquitos in inherent pricking method position, the reaction itched occurs or has change in color, current skin Histamine positive has the disadvantages that first is that with marking pen pricking method liquid title and pricking method position used in left arm mid labels, then Corresponding pricking method liquid is dripped on each position, working efficiency is low；Second is that patient can directly observe experimental phenomena, it be easy to cause disease The fear of people especially children is unfavorable for the progress of test and the treatment of disease；Third is that carrying out dropping liquid with dropper, it is easy to appear drop The case where liquid excessively sucks back again is easy that dropper is made to touch skin, causes the pollution of remaining pricking method liquid, and the system of pricking method liquid It causes this very high, causes great waste, during existing product use, the puncture needle of pricking method device is easy to dip in excessive Medical fluid causes greatly to waste, we have found in an experiment, and puncture needle dips in the number of medical fluid and the diameter phase of medical liquid container It closes, i.e., the bottle wall of medical fluid is closer apart from pricking method device distance, and due to the effect of surface tension of liquid, the puncture needle on pricking method device can be got over Do not allow medical fluid easy to stick, but if medicine bottle diameter is too small, needs frequent powder charge, cause trouble.

A kind of asthma anaphylactogen disclosed in Chinese utility model patent ublic specification of application CN204971358U Histamine positive device, this kind of asthma anaphylactogen Histamine positive device, although blocking the patient visual field, Ke Yiyou using support plate Effect prevents some patientss especially children to the fear of test；Dropper is not directly contacted with skin, it is therefore prevented that can to remaining pricking method liquid The pollution that can be generated；Depth is pierced by the distance between piercing needle needle point and active box accurate control points；It can carry out simultaneously The test of multiple pathogen, still, this kind of asthma anaphylactogen Histamine positive device also have structure in use It is cumbersome, complicated for operation, inconvenient to use, do not have the shortcomings that biggish practicability.

Currently, it is existing be used for asthma anaphylactogen Histamine positive device, it is inconvenient for use, be unfavorable for promoting the use of.
