Description

Occult blood measuring device

Technical Field

The utility model discloses medical supplies relates to technical field, especially relates to a survey occult blood device.

Background

Occult blood is referred to as "latent bleeding", i.e., the presence of red blood cells is not observed under the flesh eye or under a microscope, but there is a reaction if the test strip is used for testing, because when the red blood cells are destroyed, the hemoglobin contained therein is released. For example, to detect digestive tract bleeding requires testing for occult blood in gastric juices or feces. Generally, a method for detecting occult blood comprises the steps of coating a sample to be detected on a test paper, dripping Piramidone and hydrogen peroxide, comparing the Piramidone and hydrogen peroxide with a control card after color development, and judging whether bleeding occurs or not, but the detection method has the following problems: 1. some infectious diseases can be transmitted through feces and the like, and because the detection is carried out in an open container, germs are exposed in an open environment, and some biological safety risks exist; 2. in the process of clinical sampling and transportation to a detection point, the biological safety problem in the transportation process cannot be ensured; 3. the time from sampling to detection is long, and the detection is inconvenient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the not enough of above-mentioned prior art, provide a survey occult blood device.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a survey occult blood device, includes the test tube, and the bottom of test tube is equipped with white filter paper, and sealing connection can be dismantled in the test tube has the cotton swab, and the inside of cotton swab is equipped with the passageway, and the bottom of cotton swab is equipped with the cotton swab head, and the cotton swab head contacts with filter paper, and the lower part and the cotton swab head of passageway are linked together, and the upper portion of cotton swab is equipped with reagent storage part, and reagent storage part is linked together with the upper portion of passageway.

The test tube also comprises a comparison card which is stuck on the outer wall of the test tube.

The cotton swab is sleeved with a hose plug, and the hose plug is in sealing fit with the inner wall of the test tube.

The reagent storage part comprises a plastic sleeve and a reagent ball arranged in the plastic sleeve, the plastic sleeve comprises a first plastic sleeve and a second plastic sleeve which are communicated with each other, the first plastic sleeve is positioned below the second plastic sleeve and is connected with the cotton swab, a first reagent ball is arranged in the first plastic sleeve, a second reagent ball is arranged in the second plastic sleeve, the pilamirone stored in the first reagent ball is stored in the second reagent ball, and hydrogen peroxide is stored in the second reagent ball.

The reagent ball is tan or black.

The utility model has the advantages that: the cotton swab head dips in and gets behind the sample (gastric juice or excrement and urine) that awaits measuring, stretches into in the test tube, with hose stopper and test tube relatively sealed, kneads garrulous with first reagent ball and second reagent ball according to the order with the hand for reagent passes through the passageway and contacts with the cotton swab, makes the reaction of reagent and sample go on in airtight environment, avoids exposing the sample that awaits measuring in open environment, has reduced the biological safety risk. Because the operation is simple, the operation can be carried out after sampling, and the result is observed. On one hand, the time for sending the patient to the hospital clinical laboratory is saved, and the time for treating the patient is obtained; on the other hand, the biological safety risk of the sample in the process of submission is also reduced! The kit can be used in wards, families and any places needing to detect occult blood, and samples can be collected immediately, so that the kit is worthy of popularization.

Drawings

Fig. 1 is a schematic structural view of the present invention;

in the figure: test tube 1, cotton swab 2, passageway 21, control card 3, filter paper 4, cotton swab head 5, reagent reservoir 6, first plastic sheath 61, first reagent ball 62, second reagent ball 63, second plastic sheath 64, hose stopper 7.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1, the occult blood measuring device comprises a test tube 1, a cotton swab 2 can be arranged in the test tube 1, a hose plug 7 is sleeved on the cotton swab 2, the hose plug 7 is in sealing fit with the inner wall of the test tube 1, the hose plug 7 is penetrated through the upper part of the cotton swab 2, after the cotton swab 2 extends into the test tube 1, the hose plug 7 and the inner wall of the test tube 1 are plugged tightly, so that a closed space is formed in the test tube 1, a sample to be measured is avoided, the sample is exposed in an open environment, and the biological safety risk is reduced;

the cotton swab is characterized in that a channel 21 is arranged in the cotton swab 2, a cotton swab head 5 is arranged at the bottom of the cotton swab 2, the lower portion of the channel 21 is communicated with the cotton swab head 5, a reagent storage portion 6 is arranged at the upper portion of the cotton swab 2, the reagent storage portion 6 comprises a first plastic sleeve 61 and a second plastic sleeve 64 which are communicated with each other, the first plastic sleeve 61 and the second plastic sleeve 64 are made of soft plastics and are convenient to extrude and deform, the first plastic sleeve 61 is located below the second plastic sleeve 64 and is connected with the cotton swab 2, a first reagent ball 62 is arranged in the first plastic sleeve 61, the first reagent ball 62 and the first plastic sleeve 61 are relatively fixed, a second reagent ball 63 is arranged in the second plastic sleeve 64, the second reagent ball 63 and the second plastic sleeve 64 are relatively fixed, pilelamide is stored in the first reagent ball 62, hydrogen peroxide is stored in the second reagent ball 63, and the pilelamide and the hydrogen peroxide need to be stored in a dark place, so that the first reagent ball 62 and the second reagent ball 63 are brown or black, the upper part of the channel 21 is communicated with the first plastic sleeve 61, and the outer wall of the test tube 1 is adhered with the contrast card 3; the cotton swab head 5 dips in and stretches into the test tube 1 after getting the sample that awaits measuring and fix, and the first plastic sheath 61 of manual extrusion makes first reagent ball 62 broken, and the pilasterone that stores in the first reagent ball 62 flows into in the cotton swab head 5 through passageway 21 and contacts with the sample that awaits measuring, breaks second reagent ball 63 after a few minutes again, and hydrogen peroxide solution flows into in the cotton swab head 5 and contacts with the sample that awaits measuring, compares with contrast card 3 after the sample colour development, judges whether there is occult blood.
