Description

Excrement sample collection and detection device

Technical Field

Background

In the common fecal detection kit on the market, the collected fecal sample is usually sent into a collecting pipe filled with diluent, and after the fecal sample and the diluent are fully and uniformly mixed by shaking and other methods, the diluent with the sample is dripped into the kit.

However, most devices only have sampling devices, and cannot detect simultaneously, such as CN 114813239A, and further require additional detection reagents, which is inconvenient for operation.

Some devices can detect at the same time of sampling, for example, in the utility model disclosed in CN 213580136U, a top plate 303 is provided at the top of the test paper placing box 3, a slot 304 is provided on the top plate 303 for placing test paper, and the liquid storage box 1 of the test paper placing box 3 is communicated.

However, since the test strip is in contact with air during the detection process, secondary pollution is easily caused if the pathogen detection is performed for detecting pathogenic bacteria or viruses.

Therefore, although some devices in the prior art realize two-in-one sampling and detection, as the devices themselves have parts to be contacted with air, the influence caused by secondary pollution is difficult to avoid; meanwhile, the existing device can only detect one item at a time, and cannot detect a plurality of items of the fecal sample at the same time.

Detailed Description

Example 1

As shown in fig. 1, the utility model provides a fecal sample collecting and detecting device, which is a cylindrical container, wherein the inner cavity of the device is divided into an L-shaped cavity and a semi-cylindrical cavity, the L-shaped cavity is a sampling chamber 2, the semi-cylindrical cavity is a detecting chamber 5, and a top cover 3 is also arranged.

The sampling chamber 2 comprises a sampling device 6 and a diluent 1, and a sampling port 201 with external threads is formed in the top of the sampling chamber 2; when the sampling device 6 is inserted into the sample application port 201, the sampling device is fixed by a screw cap fixing member 602 with internal threads.

As shown in fig. 1 and 2, the sampling device 6 is a rubber head dropper, and is composed of a rubber head 601 and a dropper 603, wherein the rubber head 601 extends out of the sample adding port 201 to facilitate extrusion by a user, and the bottom of the dropper 603 is immersed in the diluent 1; graduation marks are also arranged on the dropper 603.
