Embodiment 1

[0034] Detection of free hemoglobin in nasopharyngeal exudate: open the outer packaging box 1 of the test box, take out the sampler from the box body 3, put on latex gloves, insert the sampler from the nasal cavity, and go straight to the nasopharynx along the lower nasal passage. Rotate 180 degrees left and right, and then wipe the posterior wall of the nasopharynx, pharyngeal opening of the Eustachian tube, occipital of the Eustachian tube, and hidden pharyngeal duct in order to obtain exudate; among them, the amount of exudate is 0.5-1 ml; The sample cup in the sample cup placement area 6 is pre-installed with 3 ml of tris-hydrochloric acid buffer solution with a pH value of 7.4, break the sampler, and then put the collection head 9 with seepage on the sampler into the sample cup. Mix well in the sample cup; take out two droppers from the dropper storage area 7, the two droppers are pre-installed with reagent A and reagent B respectively, add 1ml of sample solution and 0.5ml...

Embodiment 2

[0038] A detection box for detecting free hemoglobin in nasopharyngeal exudate, comprising a box body 3 and an outer packaging box 1 outside the box body 3, the outer surface of the outer packaging box 1 is provided with a color comparison plate 2, and the box body 3 is provided with a tweezers storage area 5 sunken inward, a sample cup storage area 6, a dropper storage area 7, a test pool 8 and a sampler storage area 4, the sampler storage area 7 is located above the box body 3, and the inner There is a sampler, the sampler has a total length of 14.5cm, including a collection head 9 and a handle 11 connected thereto; the material of the collection head 9 is a nylon flocking swab; the handle 11 is a plastic rod, and the middle There is a folding structure 10 that makes the handle 11 foldable, and the joint between the collection head 9 and the handle 11 is provided with a breaking part 12 made of a brittle plastic material; 1.2 cm; the dropper storage area 7 is located on both...

Abstract

The present invention relates to a method for detecting nasopharynx exudate free heme. The method comprises sampling in nasopharynx, diluting the sample solution, adding detection reagents according to a certain proportion, and determining whether heme exists according to color change. The present invention further provides a special detection box for detecting nasopharynx exudate free heme, wherein the special detection box can be specially provided for holding a vessel and detection reagents used in the detection process. According to the present invention, the detection box has a simple structure, the whole detection step can be completed only through the one detection box, the space and the reagents are saved, and operator labor burden is reduced.

Description

technical field [0001] The invention relates to a detection method, in particular to a method for detecting free hemoglobin in nasopharyngeal exudate, and at the same time, the invention also relates to a special detection box for detecting free hemoglobin in nasopharynx exudate. Background technique [0002] The free hemoglobin in nasopharyngeal exudate is often caused by the release and precipitation of free hemoglobin from cytochrome, oxygen sensor and FixL transmembrane protein of tissue tumor cells, or the exudation of tumor microcirculation. Rarely, it is not visible to the naked eye. Generally, advanced instruments and analytical chemical methods are needed for detection, which is expensive and takes a long time. Therefore, a simple and low-cost detection method is invented to quickly determine whether there is any nasopharyngeal exudate. Free hemoglobin has become an urgent problem to be solved. Contents of the invention [0003] In order to solve the problem of...
