Abstract
Description
Technical Field
The present application relates to the field of radio frequency identification technologies, and in particular, to a method and an apparatus for managing a sample library, a computer device, and a storage medium.
Background
The biological sample bank is also called biological bank (Biobank) and mainly refers to standardized collection, processing, storage and application of samples such as biological macromolecules, cells, tissues and organs of healthy and disease organisms (including human organ tissues, whole blood, blood plasma, blood serum, biological body fluid or processed biological samples, and processed biological samples such as DNA, RNA, protein and the like), and data such as clinical, pathological, treatment, follow-up and informed consent and the like related to the biological samples, and quality control, information management and application systems thereof.
At present, most hospitals or scientific research units adopt an artificial mode to manage a biological sample bank. There are problems as follows:
the space utilization rate of the preservation box is as follows: after a certain amount of samples are accumulated, manual searching and storing of the samples are difficult and error-prone, and the utilization efficiency of containers (such as refrigerators and liquid nitrogen tanks) for storing the samples is gradually reduced. Because the samples may be stored in a sorted order initially, but depending on the scientific needs, the samples are taken from different positions of the container, and a large amount of scattered vacant space is generated in the container after a period of time, and the scattered vacant space cannot be effectively utilized. It is necessary to use an information-based system to automatically allocate and search the storage locations of the samples, thereby improving the space utilization efficiency of the containers such as refrigerators.
Accuracy of sampling: this is directly related to the experimental results and the findings of the study, but is sometimes overlooked. We have once heard of such cases: a subject for studying a female disease provides a commercial service with a collection of patient samples, some of which are found to be male during the course of the study, which results in a substantial loss of value. To avoid such problems, the barcode can be scanned by a mature low-temperature barcode labeling technology to check related information in a software tool, so that the sampling accuracy can be effectively ensured.
Managing matched clinical data: the purpose of collecting and storing samples is to screen the samples of patients according to the needs of clinical scientific research, obtain the correlation between the external symptoms and the internal expressions of genes, proteins and the like of the patients through molecular biology experiments, if one sample lacks complete matched clinical data, the screening basis is insufficient, and the scientific research value of the sample is greatly reduced.
Quality control of biological samples: the method comprises the steps of sample collection and subpackaging, warehousing, sampling and ex-warehouse monitoring of the quality of the samples in the whole process, and avoids the quality problems of pollution, degradation and the like of the samples.
In the informatization process of biological sample library management, a scheme of adopting a two-dimensional code identification technology appears. The use of two-dimensional code management can standardize the management of biological sample libraries. By scanning the two-dimensional code on the side surface or the bottom of the sample tube and inquiring the corresponding database in a matching way, the information of the sample can be obtained quickly.
However, in the process of managing a biological sample library using a two-dimensional code, since a biological sample is usually stored in a low-temperature or ultra-low-temperature environment, after a biological sample tube with a two-dimensional code label is taken out, frost is easily formed on the surface of the biological sample tube, which affects normal reading of a two-dimensional code reader.
