Abstract

The invention relates to an excrement liquidizing and filtering test tube capable of integrating the functions of collecting, liquidizing and filtering. The test tube is a sample test tube designed for a clinical automatic excrement routine detection instrument. The excrement liquidizing and filtering test tube comprises a collecting tube, a filter connection layer and a liquid test tube. An opening of the collecting tube is provided with a seal cover, a transverse strip nail type sampling plate is fixed in the seal cover, a filtering material is added between the bottom of the collecting tube and a medium partition of the filter connection layer, the bottom of the collecting tube and the medium partition are annular structures, and the upper part and the lower part of the filter connection layer are respectively and closely fastened with the collecting tube and the liquid test tube which is filled with physiological saline. When the test tube is inverted, the physiological saline flows into the collecting tube to soak and dissolve an excrement sample, the excrement sample is liquidized into suspending liquid from solids, the test tube is put into a centrifuge in the state that the collecting tube is arranged on the upper end of the test tube and the liquid test tube is arranged on the lower end of the test tube, the suspending liquid of the excrement sample is subjected to centrifugal filter and most food debris is removed, and then connection between the lower part of the filter connection layer and the liquid test tube is unscrewed. Finally the collecting tube and the filter connection layer are discarded, and the liquid test tube is left for automatic detection by the instrument. With the test tube, automatic detection of an excrement routine detection instrument is enabled.

Description

Stool fluidization filters test tube

Technical field

The present invention relates to medical device technical field, the three-in-one stool fluidization of collection, liquefaction and filtration for just conventional automatic detecting instrument device design that more specifically a kind of clinical examination section office use filters test tube.

Background technology

Clinical blood, routine urinalysis Interventions Requested are realized already automation equipment and are detected, and just conventional detection also rest on manual sampling, smear, by fractographic pure manual mode.Just conventional detection mode lags significantly behind other conventional detection more than 15 years! Its reason is that blood, urine are liquid, and stool is generally (minority also has Mucous Stool, just rare) of solid, in its composition, the overwhelming majority is the swill of bulk, these swills can make instrument pipeline blockage, automation equipment detects and cannot carry out, and from the angle evaluation of science, with existing technical merit, the method that instrument detects cell, hemoglobin is not all suitable for solid sample.

Summary of the invention

In order to address the above problem, only make the fluidization of defecating, and remove the swill of bulk, just likely realize automation equipment, detect.The object of the invention is to design the three-in-one stool fluidization of a kind of collection, liquefaction and filtration for just conventional automatic detecting instrument device and filter test tube. technical scheme: stool fluidization filters test tube and is comprised of collection tube, filtration articulamentum and liquid tube.Gathering the mouth of pipe screws with seal cover, sampling plate is fixed on seal cover bosom, band nail type sampling plate lower end point, under plate body, 1/2 is band entirely, collection tube below is to filter articulamentum, at the bottom of collection tube and filter articulamentum in every between insert filtering material, form filter course, at the bottom of collection tube and filter articulamentum in every being designed to circulus hollow, being convenient to liquid flow passes through, filter the top of articulamentum, bottom respectively and collection tube, liquid tube closely fastens, physiological saline is housed in liquid tube, when test tube is inverted, physiological saline flows into collection tube from liquid tube, soak and dissolve stool sample, make ight soil be converted into suspension by solid, then test tube be take to upper end as collection tube lower end as liquid tube is correctly inserted in centrifuge, centrifugal filtration, the swill of bulk can not pass through filter course, stay in collection tube, and the cell that need to detect, hemoglobin, parasite, bacterium and physiological saline enter in liquid tube by filter course, outward winding and filter the connection of articulamentum bottom and liquid tube, discard collection tube and filter articulamentum, leaving liquid tube detects for automation equipment. advantage: (1) " band nail type " sampling plate, for the ight soil of solid forms, takes stamp to get or insert and get, and utilizes the groove in band can retain fecal sample, simple, and for Mucous Stool or just rare, the oblique body rotation of sampling plate picks fecal sample; (2) through ingenious design, " liquefaction " and " filtration " is realized by invisible spectro " liquid flow ".Test tube is inverted, physiological saline flows in collection tube from liquid tube, soak and dissolve stool sample, complete " liquefaction ", then test tube be take to upper end as collection tube lower end as liquid tube is correctly inserted in centrifuge, centrifugal filtration, the cell that physiological saline detects with needs, hemoglobin, parasite, bacterium enter in liquid tube through filtering layer from collection tube, unwanted swill is stayed in collection tube, completed " filtration "; (3) test tube compact conformation, disassembles conveniently, and experimental procedure is simple.The seal cover of outwarding winding, it is available sampling plate sampling, then be inverted test tube liquefaction stool sample, being inverted go back to afterwards upper end is that collection tube lower end is liquid tube, centrifugal filtration, finally outward winding and filter the connection of articulamentum and liquid tube, discard collection tube and filter articulamentum, leave liquid tube and detect for automation equipment; (4) process that liquefaction is filtered is all that " capping " processed, and does not have air pollution; (5) the present invention makes stool be converted into liquid by solid, and removed the swill of bulk, not only solved the problem that swill can make instrument pipeline blockage, and liquid sample is more suitable for instrument detection, the present invention makes stool examination start new page, and the cell in stool sample, hemoglobin, parasite, bacterium detect and become possibility with automation equipment.

The specific embodiment

The seal cover 1 of outwarding winding, gets ight soil with band nail type sampling plate 2 stamps, screwing hermetic lid 1, and whole test tube is inverted, and physiological saline 10 flows into and gathers in bodys 3 from liquid tube 9.By repeatedly shaking and make ight soil be converted into suspension by solid, again test tube be take to upper end as collection tube, lower end is that liquid tube is correctly inserted in centrifuge, the centrifugal 3-5 minute of 1500r/min, the swill of bulk can not pass through filter course 8, stay in collection tube, and the cell that need to detect, hemoglobin, parasite, bacterium and physiological saline enter in liquid tube 9 by filter course 8, from centrifuge, take out test tube, outward winding and filter the connection of articulamentum bottom 7 and liquid tube 9, discard collection tube and filter articulamentum, leave liquid tube 9 and put into rack for test tube, next step can carry out automation equipment detection.
