Description

A snap-fit sample tube sampling system

technical field

The invention relates to biological sample detection equipment, and relates to a snap-fit sample tube sampling system, which belongs to the technical field of in vitro medical detection.

Background technique

With the increasing demand for medical diagnosis, the volume and quantity of clinical samples to be processed are gradually increasing. Processing of clinical samples and specimens can involve transferring the original sample or specimen to a new reservoir or container suitable for performing diagnostic testing. The processing of biological samples and specimens may include steps such as accessing the contents of the initial reservoir or container by removing the lid of the initial reservoir or container, then removing a portion of the contents, and transferring the portion to a Target Reservoir or Container. In some cases, the processing may further include resetting the lid of the initial reservoir or container or otherwise closing the initial reservoir or container to preserve the remaining contents for further use test or archive.

Processing of large numbers of samples and specimens increases the time to provide diagnostic results, increases exposure of workers to repetitive motion disorders and potentially biohazardous materials, reduces uniformity of sample or specimen preparation, and reduces diagnostic performance. Program costs increase. As the volume of medical diagnostic tests increases, the number of samples and specimens required to be processed increases. Sample preparation processing for medical diagnostic testing is beneficial by reducing the time required to process specimens, reducing the potential for worker exposure to repetitive motion and biohazardous materials, ensuring consistent sample processing, and helping limit the cost of processing samples. Automated systems solve the above problems.

In vitro diagnostic equipment such as chemiluminescence immunoassay analyzers use direct chemiluminescence method based on acridine esters, used together with matching detection reagents, and are clinically used for qualitative or quantitative detection of analytes derived from human body fluids, including Autoimmune projects, infectious disease projects, hormone projects, tumor-related projects. Specimens such as serum, plasma, urine, and cerebrospinal fluid are placed in sample tubes, and different hospitals have different types of sample tubes. In the prior art, on the one hand, generally a single chemiluminescence immunoassay analyzer can only identify one type of sample tube. The types of sample tubes in different hospitals are inconsistent and difficult to fit. Generally, manual sorting and fitting of sample tubes are used to put them into corresponding in vitro diagnostic equipment such as chemiluminescence immunoassay analyzers for testing. This operation method is prone to errors and the cost of detection and analysis is high. On the other hand, in the process of sampling and testing a sample in the existing automated processing equipment, the sample is generally taken out from the sample collection, then removed, sampled, covered with a lid, and finally The next sample in the sample collection can be processed only after returning to the sample collection and waiting for a sit-in operation; because the target sample tube is usually a threaded tube cap structure, its capping and capping mechanism is relatively complex and large, if it is necessary to simultaneously The capping and capping operations of multiple sample tubes are realized, and the distance between the sample tubes and the sample tubes is large, which makes the whole processing equipment need to be larger, and increases the equipment investment and maintenance costs; on the other hand, in the existing In technology, the number of sample tubes is often large. In order to facilitate processing and reduce investment in storing samples, the density of sample tubes is relatively high during storage, that is, the gap between sample tubes and sample tubes is often very small. The state of the samples in the sample tube is not completely consistent, which also makes the sampling processing of the sample tube in the prior art basically based on the difference between the device itself and the sample tube itself. can only be sampled one by one.

In the prior art, sampling and testing of biological samples are often carried out one by one, especially for the sampling of sample tubes with threaded caps, due to the complexity of taking out and closing the cap, the cap taking and capping mechanism The relative volume is relatively large. If multiple sample tubes are to be capped and closed at the same time, there must be a sufficiently large gap between the sample tubes and the sample tubes, which requires larger sampling and testing equipment. The storage of sample tubes needs to be stored in a special place, and it is obviously impossible to store a large number of samples at low density; again, the states of the samples in different sample tubes are different (such as liquid level height, sample volume, etc.), making each sample When sampling the tubes, the requirements for the depth of the sampling gun are also different, and sampling can easily lead to sampling failure; therefore, the prior art sampling and testing equipment can only process a large number of sample tubes one by one, which requires a large amount of time. time.
