In the process of blood collection tube sorting, the prior art needs to input the identification data of the blood collection tubes first, and can only classify the blood collection tubes, but cannot sort and process them according to different testing requirements, resulting in incomplete pre-processing of the blood collection tubes and delaying the testing time; therefore, there is an urgent need for a pre-processing system for medical samples.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0033] Figure 2 It is a schematic diagram of the system principle of the present invention. DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 2 , the first aspect of the present invention provides a pre-treatment system for medical samples, including a data processing module, and a data acquisition module, a sorting execution module and a sorting execution module connected thereto, and the data processing module is connected to the information management module;

[0036] Data acquisition module: quantitatively identifies and obtains basic information data of blood collection tubes through the scanning equipment connected to it, and sends the basic information data to the data processing module;

[0037] Data processing module: Analyzes and extracts the received basic information data to generate identity tags and detection tags, and interacts with the information management module to verify the identity tags; and after the identity tag verification is passed, obtains the detection process of the corresponding blood collection tube based on the detection tag analysis, and sorts and transports the blood collection tubes in combination with the sorting execution module, and transports the blood collection tubes to the cache output area.

[0038] In the prior art, blood collection tubes are sorted either manually by staff, which is inefficient and error-prone; or by intelligent sorting machines, which require pre-entry of sorting labels before the intelligent sorting machines can sort out the corresponding blood collection tubes according to the sorting labels. The sorting efficiency is also not high enough and cannot run through the entire pre-processing process of the blood collection tubes.

[0039] The present invention applies to obtain basic information data of blood collection tubes through a scanning device, verify the identity through the identity tag in the basic information data, match the detection process according to the detection tag and calculate the priority coefficient, sort and distribute the blood collection tubes according to the priority coefficient, and at the same time improve the sorting efficiency and give priority to the urgency of the blood collection tubes.

[0040] The data processing module in the application of the present invention is respectively connected with the data acquisition module, the sorting execution module and the information management module of the hospital; the information management module is equivalent to the LIS system of the hospital, and mainly interacts with the data processing module to realize identity authentication; the data processing module mainly analyzes various data of the blood collection tube; the data acquisition module is connected with the blood collection tube pre-processing equipment, and is used to collect the data of the blood collection tube in each process.

[0041] The pre-processing equipment for blood collection tubes includes a sorting device, a centrifugal device, etc. The sorting device includes a square inclined trough, a stacking structure and a circular dividing turntable. The messy blood collection tubes are poured into the square inclined trough and processed by the stacking mechanism controlled by the servo. The blood collection tubes of various specifications (2ml, 5ml, 15ml and various specifications) are sorted in the same direction and separated into individual pieces. They are then transferred from the top of the circular dividing turntable to a self-determined position for subsequent detection, identification and sorting operations; the centrifugal device is a blood centrifuge device commonly used in medical tests. Some blood tests require centrifugation, while others do not.

[0042] In the present invention, before collecting basic information data through a scanning device, the diameters of several blood collection tubes are sorted, including: placing the several blood collection tubes in a sorting device; sorting the diameters of the several blood collection tubes according to different rules and separating them into single tubes through the sorting device.

[0043] The data acquisition module in the present invention quantitatively identifies the blood collection tubes entering the intelligent sorting stage and obtains basic information data, including:

[0044] The number of periodic identifications is determined according to the intelligent inspection capability, and the blood collection tubes are transported periodically with the number of periodic identifications as the limit; the label information on the transported blood collection tubes is identified by scanning equipment, and the label information is converted into basic information data; wherein the basic information data includes identity labels and detection labels.

[0045] Before identification, it is necessary to determine the number of blood collection tubes to be tested per unit time, that is, to determine the number of cycle identifications based on the unit time processing capacity of the hospital's intelligent testing equipment. For example, if the intelligent testing equipment can process a maximum of 1,000 tubes in one hour, the number of cycle identifications is determined to be 1,000. The purpose of setting the number of cycle identifications is to avoid a large number of blood collection tubes from piling up in the pre-processing equipment, which would affect the sorting efficiency.

[0046] After determining the number of cycle identifications, the blood collection tubes can be transported to the sorting execution module in an orderly manner, and then the label information can be collected from the blood collection tubes through scanning equipment (camera, RFID identification equipment, etc.), and then the label information can be converted into basic information data including identity tags and detection tags according to the set rules.

[0047] The data processing module in the present invention extracts the identity tag from the received basic information data and verifies the identity tag in conjunction with the information management module, including:

[0048] The identity tags corresponding to each blood collection tube are separated and extracted from the basic information data; the uniqueness and time verification of several identity tags are performed through the information management module; when any of the two verifications fail, the corresponding blood collection tubes are sorted out and an early warning is issued.

[0049] The essence of identity tag verification is to match the information in the information management module to avoid incorrect information on the blood collection tube. The identity tag is read from the basic information data. The identity tag refers to the identity tag of the blood collection tube, including the number, collection time, etc. The identity tag should be unique among the untested blood collection tubes, and the blood collection time should meet the requirements to avoid confusion and affect the test results.

[0050] In the present invention, after the identity tag is verified, the data processing module extracts the detection tag from the basic information data and matches the detection process according to the detection tag, including:

[0051] Determine the content to be tested based on the test label corresponding to the blood collection tube, and automatically match the test process based on the test content; determine whether the corresponding blood collection tube needs to be centrifuged based on the test process; and centrifuge the blood collection tube that needs centrifugal data processing.

[0052] For different test contents or test requirements, the corresponding test processes are different. Therefore, the test content is determined by the test label, and the test process (which can also be understood as the processing process) is automatically matched according to the test content. By the way, it is determined whether centrifugal treatment is required based on the test process. If centrifugal treatment is required, the corresponding blood collection tube is marked with a centrifugal mark.

[0053] The data processing module in the present invention application determines the detection priority based on the detection tag, including:

[0054] Determine the collection time, detection content and content detection time corresponding to the detection content according to the detection label; at the same time, extract the standard detection time limit corresponding to the detection content; record the sum of the standard detection time corresponding to each detection content as the standard detection time BJJ, and mark the collection time as CS, and the standard detection time limit as BJX; obtain the remaining detection time JSS through the formula JSS=α×(BJX-BJJ-CS); obtain the emergency label β corresponding to the blood collection tube, and when the remaining detection time is greater than 0, JSS / β is used as the priority coefficient of the corresponding blood collection tube; otherwise, β×JSS is used as the priority coefficient; among them, blood collection tubes with smaller priority coefficients are given priority.

[0055] α is a proportional coefficient greater than 0, and the default value is 1. The remaining time of the corresponding blood collection tube is determined by the detection label and the standard detection implementation. For example, if the collection time of a blood collection tube is 11 am, the standard detection time limit is 2 pm on the same day, and the detection content requires a standard detection time of 5 hours, then the corresponding detection remaining time is -2.

[0056] The remaining detection time and the emergency label are combined to calculate the priority coefficient. For example, if the remaining detection time is -2, -4, 5, and 6, and the corresponding emergency labels are 1, 2, 3, and 4 (the higher the emergency label, the more urgent the detection need is, and the emergency label is a positive integer), then the priority coefficients are -2×1, -4×2, 5 / 3, and 6 / 4. Then the priority coefficients are sorted from small to large. The smaller the priority coefficient, the higher the priority should be detected.

[0057] The sorting execution module in the present invention sorts and transports blood collection tubes according to the detection priority, including:

[0058] The blood collection tubes are sorted in ascending order according to the priority coefficients, and the blood collection tubes are picked out according to the sorting result; when the picked blood collection tubes have a centrifugal mark, the corresponding blood collection tubes are transported to the centrifugal device; otherwise, the blood collection tubes are transported to the cache output area.

[0059] After determining the priority coefficient, blood collection tubes with smaller priority coefficients are identified first. When a centrifugal mark is present on the corresponding blood collection tube, the blood collection tube is transported to the centrifugal device, otherwise it is transported to the cache output area. In fact, the blood collection tubes after centrifugation are also transported to the cache output area.

[0060] The sorting execution module generates a delivery signal according to the detection priority and the number of blood collection tubes in the cache output area. The delivery robot delivers the blood collection tubes in the cache output area to the intelligent inspection area according to the delivery signal.

[0061] Some of the data in the above formula are calculated by removing the dimensions and taking their numerical values. The formula is a formula that is closest to the actual situation obtained by software simulation of a large amount of collected data; the preset parameters and preset thresholds in the formula are set by technical personnel in this field according to actual conditions or obtained through simulation of a large amount of data.

[0062] Working principle of the present invention:

[0063] The data acquisition module obtains basic information data of the blood collection tube by quantitative identification through the scanning device connected to it, and sends the basic information data to the data processing module.

[0064] The data processing module analyzes and extracts the received basic information data to generate identity tags and detection tags, and interacts with the information management module to verify the identity tags.

[0065] After the identity tag is verified, the detection process of the corresponding blood collection tube is obtained based on the detection tag analysis, and the blood collection tubes are sorted and transported in combination with the sorting execution module, and the blood collection tubes are transported to the cache output area.

[0066] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
