Embodiment 1

[0027] 1. The sample collector unscrews the top cover, uses the sample fork connected with the cup cover to fork to take 1-2 grams of sludge samples, puts them back into the cup body, and tightens the cup cover for inspection.

[0028] 2. The inspector opens the bottom cover of the cup with the sludge sample collected, and inserts it into the instrument with a shock device and a negative pressure device.

[0029] 3. Add 5ml of dissolving solution from the fork rod, and the dissolving solution directly washes the sludge specimen on the specimen fork. Turn on the vibration button of the instrument for about 1 minute to make the sludge sample into a suspension. Press the suction button to drain the liquid. At this time, the coarse slag is intercepted by the filter screen, and the fine particle impurities smaller than the pore size of the retention membrane are directly removed by suction through the retention membrane (pore size 5-8 microns), and the worm eggs cannot be intercep...

Embodiment 2

[0033] 1. The specimen collector unscrews the top cover, uses the specimen fork connected to the cup cover to fork 1-2 grams of feces samples, puts them back into the cup body, and tightens the cup cover for inspection.

[0034] 2. The inspector opens the bottom cover of the cup with the feces sample collected, and inserts it into the instrument with a shock device and a negative pressure device.

[0035] 3. Add 5ml of dissolving solution from the fork, and the dissolving solution directly washes the feces specimen on the specimen fork. Turn on the vibration button of the instrument for about 1 minute to make the stool sample into a suspension. Press the suction button to drain the liquid. At this time, the coarse slag is intercepted by the filter screen, and the fine particle impurities smaller than the pore size of the retention membrane are directly removed by suction through the retention membrane (pore size 5-8 microns), and the worm eggs cannot be intercepted by the fil...

Embodiment 3

[0040] 1. The specimen collector unscrews the top cover, pours the water body sample that may contain insect eggs into the cup, and tightens the cup cover for inspection.

[0041] 2. The inspector opens the bottom cover of the cup with water samples collected, and inserts it into the instrument with a shock device and a negative pressure device.

[0042] 3. Add 5ml of solution from the fork to dissolve the impurities that may exist in the water. Turn on the vibration button of the instrument for about 1 minute to make the specimen a suspension. Press the suction button to drain the liquid. At this time, the coarse slag is intercepted by the filter screen, and the fine particle impurities smaller than the pore size of the retention membrane are directly removed by suction through the retention membrane (pore size 5-8 microns), and the worm eggs cannot be intercepted by the filter net, but are completely trapped by the retention membrane. intercepted.

Abstract

The invention discloses an interlayer cup for collecting worm eggs and a test method thereof. The interlayer cup comprises a cup body, a filtering screen and a retaining film, wherein the cup body is equipped with a top cover and a bottom cover; the filtering screen and the retaining film are arranged in the cup body so as to separate the cup body into three parts; the filtering screen is arranged close to the top cover; the retaining film is arranged close to the bottom cover. The invention has the beneficial effects that samples are concentrated through the retaining film, the detection rate of the worm eggs can be obviously increased and all the worm eggs in the samples can enter into a reading link; the whole process is performed in a device; the effluent is gathered together; the operation environment is free from sample or odor overflow; the biosafety requirement for the laboratory is met; the discomfort of the experimenter for the odor and perception of the sample test can be overcome; the operation is simple and convenient; the completing time for each sample is within 3 minutes; the interlayer cup is suitable for the parasitic ovum test for the parasitic ovum-containing water and for various samples, such as, sludge and excrements; manual coating is not required; the egg collection and the coating are simultaneously completed; the labor cost can be reduced.

Description

technical field [0001] The patent of the present invention relates to a sandwich cup for collecting worm eggs and an inspection method. Background technique [0002] Existing worm egg inspection has two kinds of direct smear inspection method and egg collection method, wherein the egg collection method is divided into floating egg collection method, sedimentation egg collection method and the like. The inspection method of the direct smear test method is to put 1-2 drops of 50% glycerin aqueous solution or ordinary water on the glass slide, take out the tested specimens the size of soybeans, such as sludge, feces, etc., mix them with them, and remove them. Coarse slag, plus a cover glass microscope to check the eggs. This method is simple to operate, but the detection rate is not high, less than 30% according to statistics, which is difficult to meet the needs of inspection. And although the egg collection method detection can improve the detection rate to more than 80%, t...
