Background
In medical examination, detection is divided into quantitative detection and qualitative detection. Quantitative assays are typically used to determine the amount of a particular pathogen or antibody. The primary conditions for quantitative detection are quantitative sampling and pretreatment of quantitative samples, including dissolution and separation. Aiming at a sample to be detected containing a large amount of insoluble substances, soluble substances to be detected need to be separated out firstly, such as: microorganisms, proteins, organic substances, inorganic substances, nucleic acids, etc. in foods; blood, proteins, nucleic acids, etc. in feces. In order to ensure the consistency of each sample to be detected, the sampling process must be quantitative, but the field weighing and sampling of each sample such as excrement, food residues and the like is unrealistic and is not easy to operate.
In the processes of food safety detection, fecal samples are widely used in medical, zoology, criminal investigation, biology and chemistry detection as samples to be detected, the samples to be detected in food and feces are usually dissolved out and centrifuged to remove sediments, and some samples need to be added with preservatives, stabilizers, purification, adsorption, buffer solutions and the like. Moreover, clinical application proves that quantitative detection of fecal occult blood is more clinically significant for clinical diagnosis. For example, Fecal Occult Blood (FOB) is the first choice for screening and testing intestinal cancer. Regardless of the detection methodology, the dissolution and extraction of occult blood in the sample and the filtration of fecal sediments are all essential processes. The utility model is simple, practical, does not need a centrifugal device and can be directly butted with the existing instruments such as a full-automatic biochemical analyzer and a full-automatic specific protein analyzer, the automatic detection can be realized without special modification of the instruments, and the practical value is very high.

Fig. 2 is a schematic structural view of the present invention when the components are not completely assembled.
Wherein, 1 sampling pipe body, 11 division boards, 22 ration holes, 2 sampling gripping parts, 21 sampling rod bodies, 3 pipe bodies and 31 filter membranes.
Detailed Description
The utility model discloses a separator is gathered to sample ration combines shown in fig. 1-2, include, sampling pipe body 1, set up sampling stick and the filter tube at 1 both ends of sampling pipe body respectively. This internal division board 11 that is provided with of sampling pipe, quantitative hole 22 has been seted up on the division board 11, the filtration of adopting the pipe body is distolaterally provided with the solution that is used for dissolving the sample. Namely, a solution is provided between the partition plate 11 and the filter pipe.
Specifically, sampling stick detachable set up in the sampling pipe body 1, the sampling stick includes that the sampling grips portion 2 and sets up in the sampling barred body 21 of 2 one ends of sampling grips portion, for realizing better collection sample, sampling barred body 21 surface is unsmooth setting. The sampling rod body 12 can be made of plastic, rubber, wood, metal, etc. The concave-convex structure can be in a spiral shape, a groove shape, a convex point shape or the like. In order to ensure the stability of connection, the sampling rod is connected with the sampling tube body 1 in a clamping or threaded manner, and specifically, the connection parts of the sampling rod and the sampling tube body 1 are respectively provided with threads which are matched with each other; or, the sampling stick with sampling pipe body 1 junction is provided with the bump, and is corresponding, sampling pipe body 1 department be provided with the mutual complex groove of bump.
The outer diameter of the sampling rod body 21 is equivalent to the aperture of the quantifying hole 22, and the quantifying hole 22 is in clearance fit with the sampling rod body 21. After sampling, the sampling rod body 21 is inserted into the quantitative hole 22, the quantitative hole 22 will scrape the redundant sample on the sampling rod body 21, and the collected sample will be left in the depression of the sampling rod. For the purpose of quantitative determination, the total concave volume of the concave-convex part of the sampling rod body is equivalent to the required collection amount. At the same time, the sample on the sampling rod 21 entering the other end of the quantitative hole 22 comes into contact with the dissolution solution and is dissolved. To accelerate dissolution, the sampling tube body 1 may be turned upside down.
The filter tube comprises a tube body 3 movably arranged in the sampling tube body 1, a filter membrane 31 is arranged at one end of the tube body 3 in the sampling tube body 1, a sealing membrane is arranged at the other end of the tube body 3, and the sealing membrane can prevent a pre-installed sample extracting solution from leaking and evaporating when the sampling tube is stored for a long time. The sealing film can be made of various materials, and in order to facilitate subsequent operations, in this embodiment, the sealing film is preferably made of aluminum foil. The filter membrane end of the pipe body 3 of the filter pipe is equivalent to the diameter of the sampling pipe body 1, and the diameter of the sealing membrane end of the pipe body 3 is larger than the diameter of the sampling pipe body 1, so that the solution is well guaranteed not to be leaked. The aperture of the filter membrane 31 is smaller than the diameter of the sediment of the sample, and the material of the filter membrane can be non-woven fabric, various fibers and the like, which is not limited herein. In order to further prevent the solution from possibly flowing into the tube 3 from the filter membrane 31 before use, the upper end surface of the filter membrane 31 is coated with an adhesive layer, and the adhesive layer is arranged on the inner side of the tube 3.
After the dissolution of the sample on the sampling rod is finished, the sealing membrane end of the filter tube is pushed, the filter tube is pushed towards the direction of the sampling rod, and at the moment, the dissolved solution after the sample is dissolved enters the tube body of the filter tube after being filtered by the filter membrane 31, so that the collection and the separation of the whole sample are finished. And (4) storing and conveying the finished sampling tube body. When the filter tube is pushed, a certain pressure is formed, the dissolving liquid impacts the filter membrane 31, the adhesive glue layer falls off, and the dissolving liquid flows into the tube body of the filter tube.
The whole collection and separation process is convenient and rapid, the separated sample can be directly used for the detection of an automatic instrument, the detection result cannot be influenced, and the problems of needle blockage and the like of the automatic instrument caused by food and excrement sediments in the prior art are also avoided.
For better verification the utility model discloses storage stability after the sampling of collection separator, following and commercially available sampling pipe have carried out the comparison, and the result is shown as table 1.
Use the commercially available sampling pipe respectively with the utility model discloses the same sample is gathered to the collection separator, arranges 2-8 ℃ in and preserves, uses FOB detect reagent box survey, and repeated survey 3 times every day calculates the average value, detects average value relative deviation and surpasses 10% until gained average value and the first day.
