[0046] Figure 1 Schematic diagram of a barcode reader reading a barcode in the related art. In the related art, the barcode reader is fixed, and the user holds the test tube rack in his hand and follows Figure 1 The pushing direction shown pushes the test tube rack carrying the sample tubes into the sample compartment of the sample analyzer, so that during the pushing process, the test tubes with bar codes on the test tube rack can pass through the bar code reader one by one.

[0047] This solution has a simple structure and low cost. However, there are some situations where the barcode cannot be read, such as the user pushes the barcode in too fast and the barcode reader cannot read it in time, or the barcode is not facing the barcode reader, or the barcode is dirty, etc., and the instrument cannot determine whether the test tube is not placed or the barcode is not read for various reasons. Therefore, the instrument cannot prompt the user to rescan and can only rely on manual review, which not only reduces work efficiency, but also has a certain probability of error.

[0048] In response to the above problems, an embodiment of the present application provides a sample container detection method, in which a first detection device and a second detection device jointly detect the sample container, and the position without identification mark on the sample storage component and the state of the sample storage component at the position without identification mark are comprehensively determined based on the first detection signal of the first detection device and the second detection signal of the second detection device. The method is simple to implement, low in cost, and can reduce manual verification operations, improve work efficiency, and reduce the probability of errors.

[0049] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0050] Figure 2 1 is a flow chart of a sample container detection method according to an embodiment of the present application. The method can be used to detect a sample container at a sample storage portion of a sample analyzer, wherein a first detection device and a second detection device are provided at the sample storage portion, the first detection device is provided adjacent to an opening of the sample storage portion, and the second detection device includes a receiver opposite to the first detection device.

[0051] Here, the sample analyzer may be a chemiluminescence analyzer, a biochemical analyzer, a cell analyzer, a coagulation analyzer, etc. In particular, the sample analyzer may be a photochemiluminescence analyzer. The sample analyzer is not limited to the analysis instruments listed here, but may be broadly understood as various analysis instruments for testing blood samples, wherein the sample in the sample tube is placed in the sample compartment of the sample analyzer in the form of a test tube rack.

[0052] See also Figure 2 The sample container detection method of the present application comprises:

[0053] S210, when the sample storage assembly for placing the sample container is placed in the sample storage portion, a first detection signal of the identification mark on the sample container is obtained by a first detection device.

[0054] The embodiment of the present application can be applied to a sample container detection system. The sample container detection system is used to detect a sample container at a sample storage portion of a sample analyzer, that is, a sample compartment, wherein the sample container detection system may include a first detection device and a second detection device.

[0055] Since the first detection device is adjacent to the opening of the sample storage portion, there is no obstruction between the first detection device and the sample test tube rack, and when the sample test tube rack is pushed into the sample storage portion, the first detection device can promptly perform a first detection on the identification mark on the sample test tube when the sample test tube rack is pushed in. The identification mark may be a label with a sample container number, and when the identification mark is an RFID (Radio Frequency Identification) tag, the first detection device may be a reader, and when the identification mark is a QR code tag, the first detection device may be a QR code scanner.

[0056] The second detection device may include a receiver opposite to the first detection device, that is, the receiver and the first detection device are arranged on both sides of the sample storage portion, so that the identification laser of the first detection device can be used as the emission light source of the second detection device. For example, the identification laser of the first detection device is directed toward the identification mark on the sample container. When there is no sample container between the first detection device and the receiver of the second detection device, the identification laser is received by the receiver. If an object passes by, the optical path of the second detection device will be cut off; if no object passes by, the optical path of the second detection device will not be cut off. The on and off of the optical path can generate an electrical signal, and the electrical signal can be used to determine whether there is an obstacle in front of the second detection device.

[0057] In addition, the second detection device may also have its own transmitter, wherein the transmitter may be arranged on the same side of the sample storage portion as the first detection device, for example, arranged side by side with the first detection device or arranged above the first detection device. The specific position may be selected according to actual conditions.

[0058] In the simplest case, the transmitter and the receiver can form a through-beam optical coupler, that is, the second detection device can be a through-beam optical coupler, which emits red light or infrared light through the transmitter, and when there is no sample container between the transmitter and the receiver, the light source is received by the receiver. If an object passes by, the optical path of the through-beam optical coupler will be cut off; if no object passes by, the optical path of the through-beam optical coupler will not be cut off. The on and off of the optical path can generate an electrical signal, which can be used to determine whether there is an obstacle in front of the through-beam optical coupler.

[0059] The optical path of the second detection device and the laser axis of the first detection device can converge on the same sample container. In other words, the position of the second detection device should ensure that the optical path of the second detection device is blocked when there is a sample container, and the optical path of the second detection device is not blocked when there is no sample container.

[0060] In actual application, the user can place multiple sample containers with identification marks on the sample storage component. The sample storage component can be a sample rack in a sample bin, and the sample rack has multiple sample slots, each of which can be used to place a sample container. The sample container can be a test tube, and the identification mark on the sample container can be a QR code label or an RFID tag. The user can place the sample storage component with multiple sample containers into the sample storage portion, and then push the sample storage component toward the first detection device disposed adjacent to the opening of the sample storage portion, and the laser axis of the first detection device sequentially shoots at the identification mark on each sample container, thereby obtaining a first detection signal of the first detection device for the identification mark on the sample container.

[0061] S211, obtaining a second detection signal from a second detection device.

[0062] In the embodiment of the present application, the sample container detection system can obtain the second detection signal of the sample container from the second detection device, wherein the second detection signal is continuously recorded during the period of detection by the first detection device, so the second detection signal has a certain sampling rate.

[0063] S212, using the first detection signal to analyze the second detection signal, and determining the position without the identification mark on the sample storage component and the state of the sample storage component at the position without the identification mark.

[0064] In a specific implementation, the sample container detection system can use the first detection signal of the first detection device to determine the position without an identification mark on the sample storage component. The position without an identification mark indicates that the first detection device has not detected the position of the identification mark. The reason may be that there is no sample container at the position without an identification mark, resulting in the first detection device not detecting the identification mark, or there may be a sample container at the position without an identification mark but the identification mark on the sample container is abnormal, resulting in the first detection device not detecting the identification mark. The embodiment of the present application can use the second detection signal of the second detection device to determine the state of the sample storage component at the position without an identification mark, so as to determine the specific reason why the first detection device did not detect the identification mark at the position, and then perform corresponding processing on the position without an identification mark according to the specific reason.

[0065] As can be seen from this example, the solution provided by the present application is used to detect sample containers at the sample storage part of the sample analyzer, wherein a first detection device and a second detection device are provided at the sample storage part, the first detection device is provided adjacent to the opening of the sample storage part, and the second detection device includes a receiver opposite to the first detection device, and when the sample storage component for placing the sample container is placed in the sample storage part, the first detection signal of the first detection device for the identification mark on the sample container is obtained; the second detection signal of the second detection device is obtained; the first detection signal is used to analyze the second detection signal to determine the position without the identification mark on the sample storage component and the state of the sample storage component at the position without the identification mark. The present application detects the sample container together by the first detection device and the second detection device, and comprehensively determines the position without the identification mark on the sample storage component and the state of the sample storage component at the position without the identification mark based on the first detection signal of the first detection device and the second detection signal of the second detection device. The method is simple to implement, low cost, and can reduce manual verification operations, improve work efficiency, and reduce the probability of error.

[0066] Figure 3 1 is another flow chart of a sample container detection method shown in an embodiment of the present application. The method can be used to detect a sample container at a sample storage portion of a sample analyzer, wherein a first detection device and a second detection device are provided at the sample storage portion, the first detection device is provided adjacent to an opening of the sample storage portion, the second detection device includes a receiver opposite to the first detection device, and the sample storage component has a plurality of spacing codes.

[0067] See also Figure 3 The sample container detection method of the present application comprises:

[0068] S310, when a sample storage assembly for placing a sample container is placed in a sample storage portion, a first detection signal of an identification mark on the sample container is obtained by a first detection device.

[0069] The embodiment of the present application can be applied to a sample container detection system. The sample container detection system is used to detect a sample container at a sample storage portion of a sample analyzer, that is, a sample compartment, wherein the sample container detection system may include a first detection device and a second detection device.

[0070] The identification mark can be a label with sample container number or sample number information. When the identification mark is an RFID tag, the first detection device can be a reader. When the identification mark is a QR code tag, the first detection device can be a QR code scanner.

[0071] The second detection device may include a receiver opposite to the first detection device, that is, the receiver and the first detection device are arranged on both sides of the sample storage portion.

[0072] Furthermore, the second detection device may also have its own transmitter, wherein the transmitter is arranged on the same side of the sample storage portion as the first detection device. Figure 4 is a front view of the positional relationship between the first detection device, the second detection device and the sample container, Figure 5 is a top view of the positional relationship between the first detection device, the second detection device and the sample container. Figure 4 and Figure 5 As shown, the transmitter and the first detection device are arranged on the same side of the sample storage portion, and the receiver and the first detection device are arranged on both sides of the sample storage portion, so that the optical path of the second detection device and the laser axis of the first detection device can converge on the same sample container. In other words, the position of the second detection device should ensure that when there is a sample container, the optical path of the second detection device is blocked, and when there is no sample container, the optical path of the second detection device is not blocked.

[0073] In actual applications, the user can place multiple sample containers with identification marks on the sample storage component, then place the sample storage component into the sample storage portion, and then push the sample storage component toward the first detection device arranged near the opening of the sample storage portion, and the laser axis of the first detection device will sequentially shoot at the identification mark on each sample container, thereby obtaining a first detection signal of the first detection device for the identification mark on the sample container.

[0074] S311, obtaining a second detection signal from a second detection device.

[0075] In the embodiment of the present application, the sample container detection system can obtain the second detection signal of the sample container from the second detection device, wherein the second detection signal is continuously recorded during the period of detection by the first detection device, so the second detection signal has a certain sampling rate.

[0076] S312: Determine positions corresponding to two adjacent interval codes according to the first detection signal.

[0077] The sample storage component has multiple interval codes, wherein the interval code is a barcode on the sample storage component that is assigned a specific string of characters. Therefore, the sample container detection system can determine the positions corresponding to two adjacent interval codes based on the specific string of characters carried by the first detection signal.

[0078] In one example, Figure 6 It is the position relationship diagram of the identification mark and the interval code. Figure 6In the example, barcodes 1, 3, 5, and 7 are interval codes. Assuming that specific character strings “ / AA”, “ / BB”, “ / CC”, and “ / DD” are assigned to interval codes 1, 3, 5, and 7 respectively, the sample container detection system can determine the positions corresponding to the two adjacent interval codes 1 and 3 according to the specific character strings “ / AA” and “ / BB” carried by the first detection signal; the positions corresponding to the two adjacent interval codes 3 and 5 can be determined according to the specific character strings “ / BB” and “ / CC” carried by the first detection signal; and the positions corresponding to the two adjacent interval codes 5 and 7 can be determined according to the specific character strings “ / CC” and “ / DD” carried by the first detection signal.

[0079] S313, determining the position without identification mark on the sample storage component according to the positions corresponding to two adjacent interval codes.

[0080] The sample slot between two adjacent spacing codes can be used to place sample containers with identification marks. Figure 6 As shown, barcodes 2, 4, and 6 are identification marks. The sample container detection system can locate the position between two adjacent interval codes according to the positions corresponding to the two adjacent interval codes, and then determine whether there is identification mark information at the position between the two adjacent interval codes, wherein the identification mark information can be a string of characters. If there is identification mark information at the position between the two adjacent interval codes, it can be determined that the first detection device has detected the identification mark at the position between the two adjacent interval codes; if there is no identification mark information at the position between the two adjacent interval codes, it can be determined that the first detection device has not detected the identification mark at the position between the two adjacent interval codes, and then the position between the two adjacent interval codes can be determined as a position without identification mark on the sample storage component.

[0081] In one example, assuming that the first detection signal carries a series of character strings: “ / AA”, “XXX”, “ / BB”, “ / CC”, the sample container detection system can determine that the first detection device has detected the identification mark at the position between two adjacent interval codes “ / AA” and “ / BB” based on the presence of identification mark information “XXX” at the position between two adjacent interval codes “ / AA” and “ / BB”; the sample container detection system can determine that the first detection device has not detected the identification mark at the position between two adjacent interval codes “ / BB” and “ / CC” based on the absence of identification mark information at the position between two adjacent interval codes “ / BB” and “ / CC”, and can further determine the position between “ / BB” and “ / CC” as a position without identification mark on the sample storage component.

[0082] In addition, the sample analyzer can be connected to the laboratory information management system (LIS) for communication. If the first detection device detects the identification mark between two adjacent interval codes, it means that there is a sample container between the two adjacent interval codes, and the identification mark on the sample container is normal, then the first detection device can obtain the sample container number of the sample container by identifying the identification mark on the sample container. The sample container number can be numbers or letters, etc., and the sample analyzer can send the sample container number to the laboratory information management system.

[0083] The laboratory information management system has registered therein information on test items to be performed that are associated with the sample tube number, so the laboratory information management system can output information on test items to be performed on the sample container based on the sample container number.

[0084] S314, determining the signal state of the position without the identification mark according to the second detection signal.

[0085] The identification laser of the first detection device is directed toward the identification mark on the sample container. Since the receiver of the second detection device is arranged opposite to the first detection device, if a sample container passes by, the optical path of the second detection device will be cut off; if no sample container passes by, the optical path of the second detection device will not be cut off, and the on and off of the optical path can generate an electrical signal, that is, generate a second detection signal, so the sample container detection system can determine the signal state of the position without the identification mark according to the second detection signal.

[0086] In addition, when the second detection device is configured as a through-beam optical coupler, the transmitter of the through-beam optical coupler can be arranged side by side with the first detection device, or arranged above the first detection device, and the emission light source of the transmitter is directed toward the identification mark on the sample container. Since the receiver of the through-beam optical coupler is arranged opposite to the first detection device, if a sample container passes by, the optical path of the through-beam optical coupler will be cut off; if no sample container passes by, the optical path of the through-beam optical coupler will not be cut off, and the on-off of the optical path can generate an electrical signal, that is, generate a second detection signal, so the sample container detection system can determine the signal state of the position without the identification mark according to the second detection signal.

[0087] In one embodiment, determining the signal state of the position without the identification mark according to the second detection signal may include:

[0088] Determine the detection time points corresponding to two adjacent interval codes; retrieve the second detection signal between the detection time points corresponding to two adjacent interval codes; and determine the signal state of the second detection signal between the detection time points corresponding to two adjacent interval codes as the signal state without the identification mark position.

[0089] Since the second detection device will also be blocked by the rack of the sample storage component when the sample storage component passes by, the number of alarm signals outputted far exceeds the number of sample containers actually missing. In order to avoid false alarms, if the first detection device does not detect the identification mark at the position between two adjacent interval codes, the sample container detection system can first determine the detection time points corresponding to the two adjacent interval codes, and then retrieve the second detection signal between the detection time points corresponding to the two adjacent interval codes. Since the position without the identification mark is the position between the two adjacent interval codes, the signal state of the second detection signal between the detection time points corresponding to the two adjacent interval codes can be determined as the signal state of the position without the identification mark.

[0090] In one example, the first detection device does not detect an identification mark at a position between two adjacent interval codes " / AA" and " / BB". Assuming that the detection time point of " / AA" is T1 and the detection time point of " / BB" is T2, the sample container detection system can retrieve the second detection signal between T1 and T2, and then determine the signal state of the second detection signal between T1 and T2 as the signal state of a position without an identification mark.

[0091] In one embodiment, the sample analyzer is equipped with a sensing signal device, and the method may further include:

[0092] Each time a sample storage assembly is placed in the sample storage portion, the control sensing signal device synchronizes the time signal of the first detection device with the time signal of the second detection device.

[0093] Since the retrieved second detection signal is the data recorded by the second detection device between the detection time points corresponding to two adjacent interval codes, in order to ensure the uniformity of the time signals of the first detection device and the second detection device, each time a sample storage component is placed in the sample storage portion, the sample container detection system can synchronize the time signals of the first detection device and the second detection device by controlling the sensing signal device (such as a compartment door opening signal) so that the time rhythms of the first detection device and the second detection device are consistent.

[0094] S315, determining the state of the sample storage component at the position without identification mark according to the signal state of the position without identification mark.

[0095] If a sample container passes by, the light path of the second detection device will be blocked; if no sample container passes by, the light path of the second detection device will not be blocked, and the second detection signal of the second detection device can reflect whether the light path of the second detection device is blocked, so the second detection signal can be used to determine whether the second detection device detects that a sample container has passed by. Based on this, the sample container detection system can determine whether the second detection device detects a sample container at the position without an identification mark based on the signal state of the second detection signal between the detection time points corresponding to two adjacent interval codes, that is, the signal state of the position without an identification mark, and further determine the state of the sample storage component at the position without an identification mark.

[0096] In one embodiment, determining the state of the sample storage component at the position without the identification mark according to the signal state of the position without the identification mark may include:

[0097] A non-identification mark position in a signal state including the first signal value is determined as a non-sample container position, and a non-identification mark position in a signal state not including the first signal value is determined as an identification mark abnormal position.

[0098] In a specific implementation, if there is no sample container at the position without an identification mark, the light path of the second detection device will not be blocked. At this time, the signal state of the position without an identification mark includes the first signal value, indicating that the second detection device has not detected the sample container at the position without an identification mark; if there is a sample container at the position without an identification mark, the light path of the second detection device will be blocked. At this time, the signal state of the position without an identification mark only includes the second signal value, and does not include the first signal value, indicating that the second detection device has detected the sample container at the position without an identification mark.

[0099] Therefore, the sample container detection system can determine whether the signal state of the position without identification mark includes the first signal value. If the signal state of the position without identification mark includes the first signal value, the position without identification mark is determined as a position without sample container, which indicates a position where no sample container exists. If the signal state of the position without identification mark includes only the second signal value but does not include the first signal value, the position without identification mark is determined as an abnormal identification mark position, which indicates a position where a sample container exists but the identification mark on the sample container has an abnormal situation. The first signal value can be a high level, such as "1", and the second signal value can be a low level, such as "0".

[0100] Fig. 7A is the signal curve diagram of the no-sample container position, Figure 7B It is a signal curve diagram that identifies the abnormal position of the mark. Fig. 7A and Figure 7BIn the figure, the horizontal axis is time, the vertical axis is the level signal, T1 and T2 are the detection time points corresponding to two adjacent interval codes, for example, T1 is the detection time point of the interval code " / AA", and T2 is the detection time point of the interval code " / BB".

[0101] like Fig. 7A As shown, in the second detection signal between T1 and T2, the signal state of the position without identification mark changes from the second signal value "0" to the first signal value "1" and then to the second signal value "0", indicating that the optical path of the second detection device between the two adjacent interval codes " / AA" and " / BB" is first blocked by the rack body of the sample storage component, and then becomes "1" because there is no sample container blocking it, and then is blocked by the rack body of the sample storage component again and becomes "0". It can be determined that the second detection device did not detect the sample container at the position between the two adjacent interval codes " / AA" and " / BB", that is, the second detection device did not detect the sample container at the position without identification mark, so it is Fig. 7A The positions without identification marks are determined as positions without sample containers.

[0102] like Figure 7B As shown, in the second detection signal between T1 and T2, the signal state of the position without the identification mark only includes the second signal value "0" and does not include the first signal value "1", which means that the light path of the second detection device is always blocked, that is, blocked by the rack body of the sample storage component and the sample container. It can be determined that the second detection device detects the sample container at the position between two adjacent interval codes " / AA" and " / BB", that is, the second detection device detects the sample container at the position without the identification mark, but the first detection device does not detect the identification mark due to the abnormality of the identification mark on the sample container, so the second detection device detects the sample container at the position without the identification mark. Figure 7B The position without identification mark is determined as the abnormal identification mark position.

[0103] In one embodiment, the sample analyzer is equipped with an alarm device, and the method may further include:

[0104] The control alarm device outputs an alarm signal according to the abnormal position of the identification mark.

[0105] There is a sample container at the abnormal position of the identification mark, but there is an abnormality in the identification mark on the sample container, which causes the first detection device to fail to detect the identification mark. Therefore, the sample container detection system can control the alarm device to output an alarm signal for the abnormal position of the identification mark to prompt the user that there is an abnormality in the identification mark on the sample container. At this time, the user can manually enter the sample container number of the identification mark or place the sample container in the sample storage component again for re-detection.

[0106] Among them, abnormal situations may include but are not limited to: the user pushes the sample container too fast, causing the first detection device to have no time to detect the identification mark on the sample container; the identification mark on the sample container is not facing the first detection device; the identification mark on the sample container is stained; the identification mark on the sample container is missing, etc.

[0107] As can be seen from this example, the present application detects the sample container together through the first detection device and the second detection device, and can determine the position without identification mark on the sample storage component and the state of the sample storage component at the position without identification mark with high precision according to the first detection signal of the first detection device and the second detection signal of the second detection device. In particular, by means of time synchronization, the first detection signal and the second detection signal can have the same time basis, so that the signal state of the second detection signal at a specific time, that is, in the time period corresponding to the position without identification mark, can be accurately determined by means of the first detection signal, so as to accurately judge the corresponding sample container state.
