Technical Field

[0001] The invention relates to the technical field of medical detection, in particular to an intestinal digestive flora sampling and detection device. Background Art

[0002] Intestinal flora, normal microorganisms in the human intestine, such as bifidobacteria, lactobacilli, etc., can synthesize a variety of vitamins necessary for human growth and development, such as B vitamins, vitamin K, niacin, pantothenic acid, etc., and can also use protein residues to synthesize essential amino acids, such as phenylalanine, valine and threonine, etc., and participate in the metabolism of carbohydrates and proteins, and can also promote the absorption of mineral elements such as iron, magnesium, zinc, etc. These nutrients play an important role in human health. Once lacking, they can cause a variety of diseases. When detecting intestinal digestive flora, it is necessary to sample feces, and the conventional detection process of feces sampling is sampling, sample delivery, dilution and detection. After searching, it is found that the intestinal digestive flora sampling detection device in the prior art is typically such as the intestinal digestive flora sampling detection device disclosed in publication number CN114317231A, including a fixed tube, a sampling detection tube is fixedly installed on the fixed tube, a telescopic sampling tube is fixedly installed at the lower part of the sampling detection tube, and an opening and closing valve and a plurality of distribution valves are fixedly installed in the sampling detection tube.

[0016] Compared with the prior art, the invention has the following beneficial effects: the intestinal digestive flora sampling and detection device,

[0017] (1) The present invention can effectively solve the problems of the existing intestinal digestive flora sampling and detection devices that require multiple operations from sampling to detection, which is easy to cause pollution and emit odor, and can only sample one sample at a time, which has low sampling efficiency and high subsequent processing costs. The electric telescopic rod pushes the fixed frame to move downward, and the process of the fixed frame moving downward pushes the vertical rod and the motor to move downward synchronously until the cross block connected to the bottom of the motor is engaged in the cross groove in the limit seat. At this time, the cross block at the bottom of the vertical rod is correspondingly engaged in the cross groove in the limit seat, and a group of sampling spoons at the bottom of the vertical rod are moved to the outside of the device for sampling operation. At the same time, the motor drives the bottom of the vertical rod from top to bottom. The two transmission rods, the rotating rod and the inserting rod drive another group of sampling spoons to rotate to mix the feces and diluent inside them. After the sampling is completed, the electric telescopic rod drives each structure to reset so that the two groups of cross blocks are separated from the cross slots. At this time, the sample is inside the device to avoid contamination. Then the staff manually rotates the control seat to rotate the motor clockwise to the top of the sampling spoon that has completed the sampling. At this time, the vertical rod can be used to drive a new group of sampling spoons below it to perform sampling operations, that is, a group of driving devices is used to drive different sampling spoons to continuously sample different samples. At the same time, the device can stir and dilute the sample while sampling, with high processing efficiency, and after sampling, multiple sampling spoons can be cleaned uniformly, which is more convenient to operate.

[0018] (2) The present invention can effectively solve the problem that the diluent addition of the existing sampling device cannot meet the use requirements of samples at different storage positions of the device through the coordinated use of the liquid inlet pipe and the one-way valve. After the sampling is completed, when the staff rotates the control seat to drive the sampling spoon to move down for sampling, the position of the liquid inlet pipe will be changed synchronously, that is, the position of the sample added through the liquid inlet pipe will be adjusted synchronously, so that a group of liquid inlet pipes can be used to meet the diluent addition requirements of different samples at different positions. The one-way valve plays a role in preventing backflow and overflow, and thereby further optimizes the structure of the device and improves the flexibility of the device.

[0019] (3) The present invention can effectively solve the problem that most existing sampling devices are of an integrated and closed structure and are not easy to clean through the anti-pollution mechanism. After the device is used, the staff can manually rotate the protective shell and the protective base in reverse to separate the inner ring from the outer ring, thereby splitting the protective shell and the protective base into two parts, thereby exposing the components inside the protective shell and the protective base for sampling and stirring, mixing and dilution, so that they can be uniformly cleaned and sterilized. In addition, when testing the diluted sample, the staff can use a syringe to penetrate the sealing cover to extract the diluted sample and transfer it to the testing equipment for testing, thereby preventing it from accidentally spilling and contaminating the working environment and the testing equipment.

The partition plate 9 serves to separate samples to avoid confusion between samples. The number of partition plates 9 can be set according to actual conditions. In addition, taking the present device as an example, the four spaces separated by the partition plate 9, when samples are stored in the first three spaces, the fourth space is in a blank state, that is, this space is not used to store samples, so as to ensure that each separated sample can be stirred, mixed and diluted.

[0037] Specifically, in the actual working process, first open the sealing cover 106 below the first transmission rod 205 to be sampled, then operate the control panel 10 to start the device, the electric telescopic rod 201 pushes the fixed frame 202 to move downward, and during the downward movement of the fixed frame 202, the vertical rod 204 is pushed to drive the cross block 209 at its bottom to engage with the limit block 207, and after the limit block 207 is pressed, it pushes the first transmission rod 205 and the rotating rod 2010 to move downward synchronously until the sampling spoon 2016 passes through the sampling channel 105 and moves to the outside of the device. At this time, the cross block 209 at the bottom of the motor 203 is engaged in the cross groove 208 in the limit block 207, and then the exposed sampling spoon 2016 can be used for sampling.

At this time, the sampling spoon 2016 stores the sample and is placed inside the anti-pollution mechanism 1. The extension block 2012 and the reset spring 2013 play the role of auxiliary support. Then the staff will engage the sealing cover 106 into the sampling channel 105, and a sampling is completed.

[0038] Next, the staff opens the sealing cover 106 below the sampling spoon 2016 to be sampled, injects the diluent into the sampling spoon 2016 storing the sample through the liquid inlet pipe 6, and then manually rotates the control seat 5 to rotate the motor 203 clockwise to the top of the sampling spoon 2016 that has completed sampling, and then repeats the above operation, that is, the electric telescopic rod 201 pushes the fixed frame 202 to move downward, and during the downward movement of the fixed frame 202, the vertical rod 204 is pushed to drive the cross block 209 at the bottom thereof to engage with the limit block 207.

At this time, the motor 203 drives the rotating rod 2010 and the insertion rod 211 at the bottom thereof from top to bottom to drive Another set of sampling spoons 2016 storing stool samples rotate to mix the stool and diluent inside them, and then after sampling, the sealing cover 106 is engaged, the diluent is added, and the control seat 5 is rotated in this cycle until all the samples that the device can store are sampled. When the sampling is completed, the staff can use a syringe to penetrate the last engaged sealing cover 106 to extract the diluted sample and transfer it to the detection equipment for detection. When the mixing degree of a storage compartment with extraction does not meet the requirements, the staff first unplugs the sealing cover 106 on one side of it, and then rotates the control seat 5 in the opposite direction to adjust the motor 203 above it, and then the motor 203 can be used to drive the sampling spoon 2016 to stir again, and all operations are completed.
