[0001] This application relates to the field of laboratory equipment, and particularly to a fecal collection and detection device. Background Art

[0002] Conventional medical tests (including human and veterinary medicine) sample types mainly include blood, urine, feces, saliva, vaginal secretions, etc. Fecal sample detection, as a conventional detection method, is a non-invasive detection that can play an auxiliary diagnostic role in the detection of various diseases and has very important clinical significance in medical tests. Calprotectin can more specifically and sensitively reflect intestinal inflammation, so the calprotectin in feces is usually detected to detect the presence of intestinal inflammation.

[0003] Chinese Patent with the authorization announcement number CN111781052A discloses a fecal sample collection device, a detection rack, and a sampling and detection method, belonging to the technical field of medical devices. The invention includes a sampling component, including a cap and a sampling rod fixed under the cap. After collecting the fecal sample, the fecal sample is mixed with a diluent in a mixing tube, and then the fecal sample collection device is inverted and fixed on the detection rack. The first convex structure inside the fixed position of the detection rack squeezes the mixing tube, so that the sample to be detected penetrates upward through the filter membrane into the detection tube, and the residue is retained in the mixing tube, thereby effectively separating the sample residue. A data label is attached to the outer wall of the fecal sample collection device. The detection rack can be directly placed into the detection device, and the detection device can read the data label and generate a detection result corresponding to the label information. The invention greatly simplifies the collection and detection process of the sample solution, ensures the accuracy of the sample detection result, and the fecal sample collection device and detection rack of the invention have simple structures and low costs, and their collection and detection methods are accurate and simple.

[0008] By adopting the above technical solution, during the sampling process, the sampling tube is deeply inserted into the feces to be collected. When the feces enters the sampling tube and fills the sampling tube, the rotating rod is rotated to drive the sampling tube to rotate, so that the blocking plate closes the bottom opening of the sampling tube, thereby preventing feces from falling out of the sampling tube as much as possible, thereby reducing the error between the collected sample amount and the required sample amount. After the blocking plate closes the bottom opening of the sampling tube, the operator drives the sampling tube away from the feces to be collected, and puts the sampling tube with the sample into the detection bottle and rotates the sampling tube so that the bottom opening of the sampling tube is opened, thereby facilitating the contact between the sample and the processing liquid for detecting the sample.

[0009] Optionally, a first plate is connected to the bottom of the grip rod, a support plate is connected to the bottom of the first plate, one end of the support plate is connected to the first plate, and the other end of the support plate is connected to the blocking plate, the sampling barrel is arranged as a semi-cylindrical body, the support plate is arranged as an arc-shaped plate, the support plate and the sampling barrel are arranged coaxially, the outer diameter of the sampling barrel is consistent with the inner diameter of the support plate, a plurality of through holes are opened on the arc side wall of the sampling barrel, and when the blocking plate closes the bottom opening of the sampling barrel, the support plate contacts the arc side wall of the sampling barrel.

[0010] By adopting the above technical solution, a through hole is opened to facilitate the discharge of gas in the sampling tube when collecting feces, so that the feces can enter the sampling tube more smoothly. After the collection is completed, the sampling tube is rotated so that when the blocking plate closes the bottom opening of the sampling tube, the support plate contacts the arc side wall of the sampling tube, and the support plate scrapes off the feces adhering to the arc side wall of the sampling tube, thereby reducing the error between the collected sample amount and the required sample amount.

A communication cavity is provided at an interval between the bottom of the inner bottle and the inner wall of the bottom of the outer bottle. The communication cavity is communicated with the test paper slot.

[0012] By adopting the above technical solution, after the sample collection is completed, the sealing plug is taken out of the inner bottle, so that the top opening of the inner bottle is opened, and the sampling cylinder is inserted into the inner bottle to make the sample contact the treatment liquid. When the reaction between the sample and the treatment liquid is completed, the grip is moved along the length direction of the grip, so as to drive the sampling cylinder to move, and the sampling cylinder pierces the thin film, so that the outlet is opened.

[0014] By adopting the above technical solution, when placing the test paper, the connecting hole is communicated with the test paper slot. The test paper is passed through the connecting hole and the test paper is placed in the test paper slot, and the limiting rod contacts the test paper, so that the test paper is stably placed in the test paper slot.

The length direction of the limiting groove is the same as the circumferential direction of the inner bottle. The limiting block is embedded in the limiting groove. The limiting block is slidably connected to the limiting groove along the circumferential direction of the inner bottle.

[0019] Optionally, a mounting plug is slidably sleeved on the holding rod, the mounting plug is embedded in the opening of the inner bottle, and the mounting plug is used for sealing the top opening of the inner bottle. When the sampling tube contacts the treatment liquid, the mounting plug seals the top opening of the inner bottle.

[0020] By adopting the above technical solution, a mounting plug is added. When the sampling tube is arranged in the inner bottle, the mounting plug seals the top opening of the inner bottle, so as to reduce the spread of bacteria in the sample to the surrounding environment.

[0022] By adopting the above technical solution, the handle is rotated to drive the rotating rod to rotate, thereby driving the sampling tube to rotate, and making the blocking plate close the bottom opening of the sampling tube or making the blocking plate face the bottom opening of the sampling tube. The sleeve and the holding rod are clamped through the second groove and the second protrusion, so that the sleeve is stably connected to the holding rod during the sampling process and after the sampling is completed, so as to avoid as much as possible the situation that the sampling tube rotates and moves away from the blocking plate after the sampling is completed, and reduce the situation that the blocking plate blocks the bottom opening of the sampling tube during the sampling process.
