Technical Field

The invention relates to a sample collecting device, in particular to an automatic excrement sample collecting device.

Background art:

operators working in the nuclear industry with radioactive work may inadvertently inhale or ingest radionuclides in the workplace due to improper protection, and the nuclides are excreted through the feces by the action of the human circulation, metabolism and excretion. Therefore, the radioactive nuclide content in the excrement of the operator (namely, the detected person) can be detected, and the amount of the radioactive nuclide ingested by the operator in the working process can be reversely deduced, so that the radiation dose of the operator can be accurately calculated and the radiation hazard can be evaluated.

Typically, the operator ingests extremely small amounts of radionuclides that are metabolized in the body. The excrement needs to be incinerated before radioactive nuclide detection is carried out on the excrement of an operator, but most of the components of the excrement are water and organic matters, and the ash-to-fresh ratio of the excrement (the ratio of the mass of the incinerated excrement to the mass of the unashed excrement) is only 1% -3%. If the detection requirement is met, all excrement samples excreted by operators for one time or multiple times need to be collected, then subsequent high-temperature ashing or wet digestion is carried out, and then radioactive analysis detection is carried out after chemical concentration. Therefore, the collection of a sufficient quantity of representative stool samples is one of the key steps in radionuclide detection.

When an existing excrement collecting device collects an excrement sample in a medical or biochemical detection process, the excrement sample is still collected by adopting a plastic cup, a cotton swab or an automatic sampling tube and the like, and the excrement sample can only be collected by adopting the mode of gram or milligram order, so that the requirement of radionuclide detection on the sample size cannot be met. If the examined person collects the excrement sample by oneself, the problems that the sampling process is not standard, the flow is complicated, the sample is difficult to store and transport, the multiple sampling and merging are difficult, the sanitation are influenced and the like exist, the discomfort of the experimenter who carries out the subsequent detection is increased, and the excrement sample is possibly subjected to cross contamination and the like. Due to the uncontrollable sampling process of the examined person, great uncertainty can be brought to the sample quantification and the detection result, and finally, the tracing and the evaluation of the radioactive detection result are difficult.

Therefore, there is a need in the art for a collection device that can collect a large number of stool samples of a subject, and has a simple, standard, reliable and sanitary collection process, wherein the collected samples can be stored in a sealed manner, and the collection device does not cause discomfort to an operator.

The working process of the control system 6 of this embodiment is: when a person to be detected presses a control switch, the sample tank 2 is conveyed to the tray 31, the tray 31 is moved to the lower part of the sampler 1 through the sample tank conveying mechanism 3, the first position sensor 611 acquires a relevant signal that the tray 31 is moved to the lower part of the sampler 1, the sample tank conveying mechanism 3 stops moving, the sample tank 2 stays below the sampler 1, and at the moment, the person to be detected samples excrement. The second position sensor 612 detects the in-position state of the subject person, and then detects the rising motion of the subject person, thereby judging the completion state of the sampling operation of the subject person. At this time, the sample tank transfer mechanism 3 is controlled to move continuously, so that the tray 31 moves continuously, the first position sensor 611 obtains information that the tray 31 moves to the sample tank sealing mechanism 4, and then the sample tank transfer mechanism 3 stops moving, so that the sample tank 2 stays at the sample tank sealing mechanism 4, and the sample tank 2 is sealed by the sample tank sealing mechanism 4. In this embodiment, when the capping device 41 pops up, the first position sensor 611 captures relevant information, and determines that the sealing of the sample tank 2 is completed, so that the sample tank transport mechanism 3 continues to move, the tray 31 drives the sample tank 2 to continue to move to the end of the transport track 32, at this time, after the first position sensor 611 acquires the position of the tray 31, the sample tank transport mechanism 3 stops moving, and the inspected person takes out the sample tank 2. After the first position sensor 611 acquires the information that the sample tank 2 is taken out, the sample tank transfer mechanism 3 is moved in reverse, the sample tank transfer mechanism 3 transfers the tray 31 in reverse, and the sample tank transfer mechanism 3 stops moving until the tray 31 returns to the initial operation position. Of course, the specimen-pot transfer mechanism 3 may also have an endless track by which the tray 31 is transferred to its initial operating position.

In this embodiment, the examinee can print the label after taking out the sample tank 2 and paste to the obvious position of sample tank 2 lateral wall and transfer to the freezer, has accomplished a sample after transferring to the freezer. When the same person to be examined samples many times in a certain period, only need to put into jar storehouse 51 the end repeatedly with same sample jar 2, be about to same sample jar 2 place repeatedly on the tray 31 that is in initial operating position, can collect same person to be examined's a lot of excrement and urine sample after sampling many times.
