Method and equipment for making defecate detection solution, and diafiltration device thereof

Abstract

The invention provides a diafiltration device, which comprises a sampling component, a top cover and a sample tube body, wherein a through hole is formed in the center of the top cover; the sampling component comprises a connecting cylinder and a sampling part, the connecting cylinder is concentric with the through hole and is connected with the through hole in a rotating manner, the sampling component is concentrically connected with the connecting cylinder and can collect suspension; the sample tube body can be connected with the top cover so that the sample tube body is arranged at the outer side of the sampling component in a sheathed manner. The through hole, the connecting cylinder and the sampling part, which are coaxially arranged, replace a sampling component and an insertion hole which are simultaneously arranged on a top cover with an original structure, the dilution, mixing and sampling operations of the diafiltration device can be realized only by the through hole in the center of the top cover, the problem that the occupation area is large as the sampling component and the insertion hole are simultaneously arranged on the top cover can be solved, the design dimensions of the top cover and the sample tube body can be reduced, and the space resources can be saved. The invention further provides equipment for making a defecate detection solution by matching with the diafiltration device, and a method for making the defecate detection solution.

Description

technical field [0001] The present invention relates to the technical field of testing equipment, and more specifically, relates to a dilution filter device and a method for preparing a stool test solution. The present invention also relates to a device for preparing a stool test solution with the above-mentioned dilution filter device. Background technique [0002] Stool testing is one of the main tests for checking a patient's condition. Before testing the formed components of stool, it is generally necessary to use equipment for preparing stool testing liquid, perform dilution, filtration and sampling operations to obtain a suspension for the detection of formed components, and the specific process is: collect stool samples, and then The specimen is placed in the dilution filter device (the dilution filter device is a component of the equipment for preparing stool test solution), and then the dilution filter device containing the stool sample is installed on the stirring ...

AI Technical Summary

Problems solved by technology

However, due to the large cross-sectional area of ​​the top cover 03 and the sample tube body 04 of the dilution filter device with the above structure, its overall size is relatively large, and the occupied space is also large. It is not set concentrically with the sample tube body 04. In the process of ensuring the alignment of the sampling needle and the insertion hole 02, it increases the difficulty of installing the dilution filter device on the equipment for preparing the stool test solution
