Description

A storage tube for quality control analytes

technical field

The utility model relates to the technical field of biochemical detection, in particular to a storage tube used for quality control analytes.

Background technique

The current automatic quality control has no literature and materials for reference, and has been in the exploratory stage. ISO15189 and CLSI do not clearly provide customized control rules based on a certain project. There is only a relatively simple requirement, which requires that: every day Run at least one quality control for each item, with no less than two levels for each item.

The structure of the existing biochemical detection line: main engine ---- storage box --- mechanical arm on the conveyor belt, sampler, analyzer, capping device ---- refrigerator, etc. The purpose of the assembly line itself is to perform biochemical analysis, that is, to automatically perform various tests on blood samples from a large number of patients. The entire process is automated. At present, many manufacturers such as Abbott have biochemical test lines.

Specifically, the process of biochemical detection is as follows:

On the assembly line, the robotic arm grabs the storage tube from the refrigerator (initially, the storage tube has a cover, which contains the patient's blood), and then enters the cap-opening module, and the cap-opening is completed; the next step is to enter the analysis unit, the biochemical analyzer, to aspirate the sample. Done; the next step is to enter the capping module, the capping is completed; the next step is to enter the refrigerator. After the storage tube enters the refrigerator, wait for 10 to 15 minutes to complete the biochemical analysis.

The material of the patient's blood sample storage tube is a mixture of plastic and glass fiber (the tube used by the hospital to store blood after the patient draws blood). After the sampling is completed, seal a film on the nozzle. The material of the film is generally a soft metal material such as aluminum foil, and there is glue on the surface. The assembly line uses the downward pressure to stick the film to the nozzle. The membrane needs to be removed for the next sampling. For patient sample testing, sealing and peeling the film generally only needs to be performed once or twice, and then the sample storage tube will be discarded.

According to the structure of the assembly line, the assembly line can be used for quality control of biochemical detection, that is, automatic quality control. Only a set of automatic quality control software programs are required to change some processes of the pipeline to perform quality control.

The main difference between quality control and patient sample testing is that quality control needs to be performed periodically, that is, the above process needs to be performed several times a week, or even several times a day. Therefore, the storage tube is frequently sealed and uncovered. The design of the existing storage tube is not suitable for sealing and peeling the film multiple times.

CN305142959S provides a peripheral blood sample tube, which is used for the collection, transportation and preservation of peripheral blood samples in medical institutions, and can also be used for the transfer, transportation and preservation of other collected blood samples. . Therefore, the contact area with the film is relatively large, and it is easy to stick when the film is sealed, but it may not be peeled off when the film is peeled off, especially when the film is peeled off multiple times. The problem occurs when the membrane is used.

Therefore, it is an urgent technical problem to provide a storage tube for quality control analytes in the field of biochemical detection technology.

Specifically, a downward pressure will be applied to the nozzle 1 during film sealing. Since the nozzle 1 in this embodiment is very thin, it may be deformed or broken when subjected to the down pressure. In order to strengthen the nozzle 1 to make it Instead of being damaged by the film sealing device of the assembly line, several reinforcing ribs can be provided at the nozzle 1. In other embodiments, the reinforcing ribs can also be arranged on the outer wall of the nozzle 1 . Because in some application scenarios, the storage tube has a cover, and the reinforcing rib 6 on the inner wall may result in the inability to add a plug or the sealing is not strict, so the reinforcing rib is preferably arranged on the outer wall.

Further, the material of the storage tube contains glass fibers, which can make the tube body hard and not easily deformed when subjected to down pressure.

Fig. 4 also provides three preferred solutions, the bottom cavity 5 is provided with a filler 7, and some brands of the assembly line are installed on the base of the storage tube, during the detection process, the storage tube needs to be removed from all If the bottom cavity 5 is hollow, the ejector pin on the base cannot lift the storage tube, so the filler body needs to be provided in the bottom cavity 5 7, so that the ejector pin of the base can push up the entire storage tube.

In the first alternative, the packing body 7 is a short column, the upper part of the short column is connected to the center of the upper end of the bottom cavity 5 , the radius of the short column is smaller than the radius of the bottom cavity 5 , and the short column is The purpose of the column is to cooperate with the automatic biochemical detection pipeline.

The material of the film is generally a soft metal material such as aluminum foil, and there is glue on the surface. On the nozzle 1; the storage tube after the final sealing film is returned to the refrigerator.

Quality control needs to be performed periodically, that is, the above process needs to be performed several times a week, or even several times a day. Therefore, the storage tube is frequently sealed and uncovered. The thickness of the top tube wall of the nozzle 1 is only 0.1 mm, so the contact area with the film is small, and the sealing film will not be unable to be peeled off during frequent operations.

In order to clearly illustrate the purpose of the storage tube, the embodiment of the present invention introduces a quality control method for clinical medical body fluid detection, which automatically performs quality control operations based on a clinical medical body fluid detection system. As shown in FIG. 5 , the clinical medical body fluid detection system (equivalent to the pipeline in the above embodiment) includes a detection system 10 and a data management system 20, and the data management system can be a computer or a server.

The magnetic switch on the assembly line in the above embodiment can be set at any module before the analyzer 16, so that the storage tube can be mixed before reaching the analyzer 16.

The data management system 20 is connected and communicated with the detection system 10 , management system software is installed in the data management system 20 , and the management system software in the data management system 20 is used to control and control the operation of the detection system.

The sampling module 11 sends the bodily fluid samples into the orbital transmission module 111, and the orbital transmission and transmission module 111 transfers the bodily fluid samples to the analyzer, and the analyzer samples and detects the bodily fluid samples.

Storage modules store sealed sample tubes in a temperature-controlled environment and can include storage benches and automated freezers.

The working process of the clinical medical body fluid detection system will be described below in conjunction with each module of the clinical medical body fluid detection system. The body fluid sample is placed in a test tube, and the test tube is provided with an information label for marking the body fluid sample. The specific label can be an identification code. For example, a two-dimensional code or an electronic label, etc., first, when the body fluid sample is detected, the sample injection module 11 places the body fluid sample on the rail transmission module 111, and the identification module 12 identifies the label on the test tube. After the identification is completed, such as If centrifugation is required, enter the centrifuge module 13 for automatic centrifugation, and then enter the capping module 14 or the membrane stripping module 15. The specific selection can be made according to the sealing material on the test tube. After the capping or membrane stripping is completed, the rail transfer module 111 The sample is transported to the analyzer, the analyzer can identify the body fluid sample information through the label on the test tube, the analyzer performs suction analysis on the sample, and then enters the film sealing module 17 for film sealing. After the film sealing is completed, the rail transmission module 111 The body fluid sample is transferred to the storage module 112, and the sample output module 19 returns the body fluid sample to the storage module for storage.

Based on the clinical medical body fluid detection system shown in FIG. 5 , the quality control method for clinical medical body fluid detection provided by the embodiment of the present invention is shown in FIG. 6 , and the quality control method may include the following steps:

S10: Acquire detection data of at least one detection item of the body fluid sample. In this embodiment, the body fluid sample may include blood, urine, and tissue fluid. Test items can include the detection of various enzymes in body fluids. For example, alanine aminotransferase, alanine transferase, etc., and detection of various ions, such as potassium, calcium, sodium, etc. Or other testing items, such as albumin, globulin and other testing items. Exemplary so-called test data are test results of test items of a patient.

可以得到移动平均值。当然，在本实施例中，也可以采用按照顺序取两个数据做平均值。作为示例性的实施例，在本实施例中，可以采用一次移动平均法或二次移动平均法。S20: Perform moving average calculation on the detection data to obtain a moving average of the detection items. As an exemplary embodiment, the calculation of the moving average may adopt the following method: if the measured values (x ₁ , x ₂ , _{x 3} , . average value. E.g

A moving average can be obtained. Of course, in this embodiment, two pieces of data can also be taken in order as an average value. As an exemplary embodiment, in this embodiment, a first-order moving average method or a second-order moving average method may be adopted.

S30: Determine whether the moving average of the detected items exceeds a preset threshold. As an exemplary embodiment, the preset threshold may be determined according to the detection results of the hospital detection samples. In this embodiment, the preset threshold may be changed at any time according to the detection data obtained by the detection, and may be determined by time according to the detection moving average. Sequentially trace the moving average. When the moving average point falls within the preset threshold, the detection data of the test item is considered to be normal. When the moving average point falls outside the preset threshold, it is considered that the test result of the test item may exist. question.

In order to avoid random phenomena, for example, when the analyzer absorbs the body fluid sample in the test tube, it absorbs air bubbles, etc., resulting in a large drift in the detection data. In an exemplary embodiment, it is confirmed whether the moving average exceeds a preset threshold value. , it can continuously detect whether multiple moving averages exceed the preset threshold, or continuously detect whether there are multiple moving averages exceeding the preset threshold among the multiple preset thresholds, that is, multiple movements occur at intervals in a relatively short period of time. When the mean exceeds a preset threshold.

Specifically, it is determined whether the moving average of the detection items in the multiple consecutive body fluid samples exceeds the preset threshold is greater than the preset number; when the moving average of the multiple consecutive body fluid samples exceeds the preset threshold The number of When the number is reached, confirm whether the moving average exceeds the preset threshold. As an exemplary illustration, when the moving average exceeds the preset threshold, in order to avoid random situations, starting from the first moving average that exceeds the preset threshold, it is possible to continuously observe whether the subsequent two or three moving averages are If two or three moving averages exceed the preset threshold continuously from the first moving average that exceeds the preset threshold, it can be confirmed that the moving average of the current detection item exceeds the standard, and a prompt message is output. For example, it can be displayed on the operation screen of clinical medical body fluid detection that there may be some problems in the detection of a certain item, or output voice prompts and so on.

As another optional embodiment, starting from the first occurrence of a moving average that exceeds a preset threshold, continuously observe whether there are more than two moving averages that exceed the preset threshold in the following five moving averages, and when more than two , confirm that the moving average of the current test item exceeds the standard, and output a prompt message. Those skilled in the art should understand that the number of moving averages in the above embodiment is only an example for convenience of description, and other numbers of moving averages are also within the protection scope of this embodiment. When the moving average value of the detection item exceeds the preset threshold, the process goes to step S40, and when the moving average value of the detection item is within the preset range, the process returns to step S10.

S40, controlling the clinical medical body fluid detection system to perform quality control on the detection items. Specifically, the quality control substance (quality control analyte) is placed in the storage module in the clinical medical body fluid detection system in advance, and after the moving average value of the detection item exceeds the preset threshold, the sample extraction module 19 is controlled to take out the quality control material in the storage module. The product is placed on the track transmission module 111 to enter the analyzer, and the quality control analysis of the corresponding test items whose moving average exceeds the preset threshold is performed.

As an exemplary embodiment, as shown in FIG. 5 , the rail transmission module 111 may include an emergency channel 113 , and when the moving average value of the detection item exceeds a preset threshold, the quality control product may be controlled to enter the emergency channel 113 and enter the analyzer preferentially. Quality control to complete the quality control of the current testing items in the shortest time.

As an exemplary embodiment, when the moving average value of the detection item exceeds a preset threshold, the body fluid sample continues to be detected, and the subsequent body fluid sample with the detection item when it is confirmed that the moving average value is out of control is marked with an unchecked label. Specifically, the to-be-checked label can be associated with the identification label of the body fluid sample. Since when the moving average exceeds the preset threshold, it cannot be completely confirmed that the detection item is out of control. Therefore, normal detection of the sample can be continued to avoid affecting the detection efficiency.

As another exemplary embodiment, when the moving average value of the detection item exceeds a preset threshold, the clinical medical body fluid detection system is controlled to offline the detection item, and the detection item offline may be stopping the current analyzer injection. Specifically, the body fluid sample with the detection item can be stopped from entering the current analyzer. In this embodiment, after stopping entering the current analyzer, the body fluid sample with the detection item is transported to other online analyzers to continue sampling detection.

As an exemplary embodiment, when the moving average of a certain test item exceeds a preset threshold, after the quality control product enters the analyzer corresponding to the test item through the emergency channel 113, the analyzer 16 is controlled in the quality control according to the preset quality control rules. The indoor quality control data corresponding to the test item is collected from the control product, and the indoor quality control data is analyzed. Specifically, the quality control rules corresponding to different test items are based on the actual situation. At least one rule can be selected from the Six Sigma sigma rules for quality control, and the quality control rules can include: 13s, 22s, 232s, r4s, 6x, 8x, 9x , 10x, 15s, etc.

The control rule takes 13s as an example. When the indoor quality control data exceeds the quality control rule for 13s, the quality control result is determined to be out of control. When the quality control result is out of control, the body fluid sample of the current test item is re-examined. When the moving average of the detected items exceeds the preset threshold, the analyzer continues to inject and detect, and the body fluid sample with the label to be checked can be re-checked. Because when the moving average exceeds the preset threshold for the first time, in order to prevent random events from occurring, the subsequent samples will be marked only when the number of consecutive moving averages exceeding the preset threshold is greater than the preset number. , therefore, only the body fluid samples with labels to be checked are rechecked, and omissions may occur, so it is also necessary to recheck several samples before the body fluid samples whose moving average exceeds the preset threshold. Specifically, all samples from the time when the moving average exceeds the preset threshold for the first time to the time when the quality control product is used for quality control and the quality control result is out of control are rechecked.

Obviously, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation manner. For those of ordinary skill in the art, changes or modifications in other different forms can also be made on the basis of the above description. There is no need and cannot be exhaustive of all implementations here. And the obvious changes or changes derived from this are still within the protection scope of the present invention.
