Description

Technical Field

[0001] The present invention belongs to the technical field of medical detection, and particularly relates to an intelligent specimen submission device and management system based on the Internet of Things. Background Art

[0002] Mixing up specimens with each other is the most common error in specimen inspection. Specimen collection and processing belong to pre-analytical quality management, which can affect the "accuracy" of test results. The pre-analytical stage "starts from when the clinician issues an order and includes, in chronological order, steps such as making a test request, patient preparation, specimen collection, transportation to the laboratory and transfer within the laboratory until the start of the analytical test procedure". Any error in any link of this process will affect the overall quality control. The transportation link should be minimized and the storage time should be shortened. Specimen transfer should be carried out by dedicated personnel, professionals and with institutional constraints to avoid inaccurate test results caused by objective and subjective factors during the specimen transfer process.

[0004] It can be seen that the following problems exist in the current specimen submission: the submission reminder is not timely, and it is impossible to give targeted submission prompts according to different states. Summary of the Invention

[0005] Therefore, the present invention provides an intelligent specimen submission device and management system based on the Internet of Things to overcome the problems in the prior art that the submission reminder is not timely and it is impossible to give targeted submission prompts according to different states.

[0006] To achieve the above object, the present invention provides an intelligent specimen submission device and management system based on the Internet of Things, including,

[0007] A specimen partition placement module, which partitions and places specimens with different detection requirements by setting a specimen rack with a multi-layer structure. Each layer of the specimen rack is provided with a sensor for detecting the number of specimens on this layer;

[0008] A timing signal sending module, which can automatically complete the function of signal sending according to the obtained instruction and record the number of signal sendings;

[0009] A duration detection module capable of monitoring the specimen placement duration when a specimen is placed in the specimen partition placement module;

[0010] A frequency detection module capable of monitoring the signal transmission frequency when a specimen is placed in the timing signal sending module;

[0011] A data analysis unit, which is respectively connected to the timing signal sending module, the duration detection module, the frequency detection module, and each of the sensors, and is capable of sending instructions to the timing signal sending module;

[0012] The data analysis unit obtains the data detected by each of the sensors to determine the specimen placement status, and determines the signal transmission cycle interval of the timing signal sending module according to the determined specimen placement status and the data detected by the sensors. Or, it determines to send an alarm signal according to the specimen placement duration detected by the duration detection module. Or, it re-determines the initial value of the signal transmission cycle interval according to the signal transmission frequency and the specimen placement duration.

[0013] Further, the specimen partition placement module includes

[0014] The specimen rack adopts a double-layer design. The upper layer is an urgent specimen area, and the lower layer is a general specimen area. The urgent specimen area is provided with a first gravity sensor for detecting the number of specimens stored in the urgent specimen area, and the general specimen area is provided with a second gravity sensor for detecting the number of specimens stored in the general specimen area.

[0015] Further, it also includes

[0016] An alarm module, which is connected to the data analysis unit and can give an alarm according to an alarm instruction;

[0017] An automatic disinfection module, which is connected to the data analysis unit and can automatically complete the disinfection function according to the obtained instruction;

[0018] The data analysis unit can also determine whether to send a disinfection instruction to the automatic disinfection module according to the data detected by each of the sensors.

[0019] Further, four placement states are preset in the data analysis unit, including

[0020] The first specimen placement state is that a specimen is detected to be placed only in the urgent specimen area;

[0021] The second specimen placement state is that a specimen is detected to be placed only in the general specimen area;

[0022] The third specimen placement state is that specimens are detected to be placed in both the general specimen area and the urgent specimen area;

[0023] The state of no specimen placement means that no specimen is detected in both the ordinary specimen area and the urgent specimen area.

[0024] The data analysis unit determines the placement state of the specimen based on the data detected by the first gravity sensor and the second gravity sensor, and obtains the number of specimens placed in each specimen area.

[0025] Further, the data analysis unit sets the first specimen placement state and the second specimen placement state as single-instruction influence states, and sets the three-specimen placement state as a composite-instruction influence state;

[0026] When in the state of no specimen placement, the data analysis unit sends a disinfection instruction to the instruction transmission unit.

[0027] Further, when in the single-instruction influence state, the data analysis unit determines the signal transmission period based on the number of specimens stored in a single layer. Within a certain range of the number of specimens, the more specimens are stored, the shorter the signal transmission period, and a minimum signal transmission period interval is set.

[0028] Further, when in the composite-instruction influence state, the data analysis unit determines the calculation method of the signal transmission period interval based on the number of specimens stored in two layers;

[0029] The calculation method of the signal transmission period interval is to determine the signal transmission period interval only by considering the number of specimens placed in the urgent specimen area, or to supplement and calculate the method of only considering the number of specimens placed in the urgent specimen area to determine the signal transmission period interval.

[0030] Further, the data analysis unit obtains the data detected by each sensor to determine the number of specimens stored in each layer, and compares the specimen placement duration detected by the duration detection module with the standard specimen placement duration to determine whether to send an alarm signal to the alarm module;

[0031] The value of the standard specimen placement duration is related to the number of specimens stored in each layer. Within a certain range of the number of specimens, the more specimens are stored, the smaller the value of the standard specimen placement duration.

[0032] Further, the data analysis unit re-determines the initial value of the signal transmission period interval according to the signal transmission times and the specimen placement duration, including,

[0033] When both the specimen placement duration and the signal transmission times are within the standard range, it is determined that the initial transmission period interval does not need to be adjusted;

[0034] When the specimen placement duration or the signal transmission times exceed the standard range, it is determined that the initial transmission period interval needs to be adjusted to be shortened;

[0035] The data analysis unit is provided with a minimum value of the initial transmission cycle interval, and determines whether the adjustment result of shortening the initial transmission cycle interval is effective;

[0036] The standard range includes the basic specimen placement time and the basic signal sending times.

[0037] Furthermore, when the initial transmission cycle interval needs to be shortened, the data analysis unit analyzes the specimen placement time and the number of signal transmissions to determine the influencing parameters for shortening the initial transmission cycle interval.

[0038] If only one of the specimen placement time or the number of signal transmission times is used as the influencing parameter for shortening the initial transmission cycle interval, the calculated theoretical value of the initial transmission cycle interval is determined according to the corresponding preset compensation parameter and the preset standard range corresponding to the influencing parameter;

[0039] If the specimen placement time and the number of signal transmissions are both used as influencing parameters for shortening the initial transmission cycle interval, the preset compensation parameter corresponding to one of the influencing parameters is reduced according to a preset ratio, and the preset compensation parameter corresponding to the other one remains unchanged, and the corresponding preset standard ranges are combined to determine the calculated theoretical value of the initial transmission cycle interval;

[0040] The shortened initial sending cycle interval is determined based on the calculated relationship between the theoretical value and the minimum value of the initial sending cycle interval.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] Through partition design, specimens can be classified and managed. Classification management not only facilitates identification, but also optimizes the workflow. Urgent specimens are placed on the upper layer, which is more conspicuous and given priority by staff to reduce missed inspections or delays. Hardware partitions block the path of human error operations. Compared with pure label management systems, partition design greatly reduces the specimen misplacement rate.

[0043] Furthermore, the real-time detection of the specimen placement time and the number of signal transmission times by the duration detection module and the frequency measurement module can provide the data packet analysis unit with more accurate data, making the regulation of the signal transmission interval time more timely. This precise adjustment further improves the efficiency of specimen delivery.

[0044] Further,

[0045] The timing signal sending function ensures that the specimens can be collected and processed in a timely manner, eliminating the need for manual repeated confirmation of whether there are specimens in the specimen rack, reducing manual intervention, and improving management efficiency.

[0046] Further,

[0047] Through the automatic disinfection function, the operation of manual disinfection is replaced, eliminating the possible mistakes and the possibility of incomplete disinfection during the manual disinfection process, reducing the bacterial growth on the specimen racks, and reducing the risk of cross-infection to ensure hygienic safety.

[0048] Furthermore,

[0049] The data analysis unit monitors the status of the specimens in real time and transmits it to the corresponding working modules. For different specimen placement situations, differential management is adopted, greatly reducing the manual transportation cost of specimen submission, realizing the status tracking of specimens, ensuring the priority processing of urgent specimens, and improving the management efficiency.

[0059] The present invention provides an intelligent specimen submission device and management system based on the Internet of Things, including

[0060] a specimen partition placement module that partitions and places specimens with different detection requirements by setting a specimen rack with multiple layers. Each layer of the specimen rack is provided with a sensor for detecting the number of specimens on this layer;

[0061] a timing signal transmission module that can automatically complete the function of signal transmission according to the obtained instruction;

[0062] a duration detection module that can monitor the specimen placement duration when the specimen partition placement module places specimens;

[0063] a number detection module that can monitor the signal transmission times when the timing signal transmission module places specimens;

[0064] a data analysis unit that is respectively connected to the timing signal transmission module, the duration detection module, the number detection module, and each of the sensors, and can send instructions to the timing signal transmission module;

[0065] The data analysis unit obtains the data detected by each of the sensors to determine the specimen placement state, and determines the signal transmission period interval of the timing signal transmission module according to the determined specimen placement state and the data detected by the sensors. Or, it determines to send an alarm signal according to the specimen placement duration detected by the duration detection module. Or, it re-determines the initial value of the signal transmission period interval according to the signal transmission times and the specimen placement duration.

[0066] Specifically, the specimen zoning placement module includes

[0067] A specimen rack, which is designed with two layers. The upper layer is the urgent specimen area, and the lower layer is the ordinary specimen area. The urgent specimen area is provided with a first gravity sensor 2 for detecting the number of specimens stored in the urgent specimen area, and the ordinary specimen area is provided with a second gravity sensor 4 for detecting the number of specimens stored in the ordinary specimen area. Through the zoning design, the classified management of specimens is realized. Classified management is not only convenient for identification but also can optimize the work process. Urgent specimens are placed on the upper layer, which is more conspicuous, and staff can give priority to processing them, reducing missed inspections or delays. By blocking the path of human misoperation through hardware zoning, compared with a pure label management system, the misplacement rate of specimens is significantly reduced by the zoning design.

[0068] Specifically, the timing signal sending module includes a signal sending device 3, which is connected to the data analysis unit and sends information to the staff at regular intervals according to the instructions of the data analysis unit.

[0069] Among them, the signal sending device 3 includes Wi-Fi, or Bluetooth, etc.

[0070] Through the timing signal sending function, it is ensured that specimens can be collected and processed in a timely manner, eliminating the need for manual repeated confirmation of whether there are specimens in the specimen rack, reducing manual intervention, and improving the notification efficiency.

[0071] Specifically, the automatic disinfection module includes

[0072] An ultraviolet lamp 1, which is connected to the data analysis module. When the data analysis module determines that the placement state is a state without specimens placed, the ultraviolet lamp 1 is started according to the instructions obtained from the data analysis module for disinfection. The disinfection time can be set according to requirements, usually 10 - 15 minutes. After the disinfection is completed, the system automatically turns off the ultraviolet lamp 1 and records the disinfection log.

[0073] Through the automatic disinfection function, the operation of manual disinfection is replaced, eliminating the possibility of incomplete disinfection due to possible mistakes during manual disinfection, reducing the bacterial growth on the specimen rack, reducing the risk of cross-infection, and the disinfection duration can be dynamically adjusted through the disinfection log and the disinfection effect to ensure health and safety.

[0074] Specifically, the alarm module is connected to the data analysis unit. If the specimen placement time is too long, exceeding the alarm time H, the data analysis module issues an instruction, and the alarm module starts according to the obtained instruction until the specimen is picked up.

[0075] Among them, the alarm module includes a buzzer or an LED, etc.

[0076] The alarm module can remind other staff members when the staff member responsible for submitting specimens has a problem and fails to collect the specimens in a timely manner, indicating that the specimens have not been submitted in time, and notify the staff member responsible for submitting specimens to submit them in time through other personnel.

[0077] Specifically, the duration detection module is connected to the specimen partition placement module. When specimens are placed, it records the placement time of the specimens and performs real-time detection of the placement duration of the specimens. The real-time detection of the specimen placement duration can provide more accurate data for the data packet analysis unit, making the regulation of the signal transmission interval duration more timely. Through this precise adjustment, the efficiency of specimen submission is further improved.

[0078] Specifically, the frequency measurement module is connected to the timing signal transmission module. When specimens are placed, it performs real-time detection of the signal transmission frequency. The real-time detection of the signal transmission frequency can provide more accurate data for the data packet analysis unit, making the regulation of the signal transmission interval duration more timely. Through this precise adjustment, the efficiency of specimen submission is further improved.

[0079] Specifically, the data analysis unit can obtain the data information detected by the first gravity sensor 2 and the second gravity sensor 4 in real time, analyze the detection results, determine the specimen placement status in the specimen partition placement module, and determine the working modes of the timing signal transmission module, the automatic disinfection module, and the alarm module according to the specimen placement status, the data detected by the sensors, the specimen placement duration, and the signal transmission frequency.

[0080] Specifically, the data analysis unit obtains the data detected by each sensor to determine the specimen placement status, and determines the signal transmission cycle interval of the timing signal transmission module according to the determined specimen placement status and the data detected by the sensors. Or, it determines to send an alarm signal according to the specimen placement duration detected by the duration detection module. Or, it re-determines the initial value of the signal transmission cycle interval according to the signal transmission frequency and the specimen placement duration.

[0081] Among them,

[0082] The first specimen placement status is that specimens are placed and detected only in the urgent specimen area;

[0083] The second specimen placement status is that specimens are placed and detected only in the ordinary specimen area;

[0084] The third specimen placement status is that specimens are placed and detected in both the ordinary specimen area and the urgent specimen area;

[0085] When the data analysis unit is in the first specimen placement status, it analyzes the number of specimens placed in the urgent specimen area to determine the signal transmission cycle of the timing signal transmission module;

[0086] When the data analysis unit is in the second specimen placement state, it analyzes the number of specimens placed in the ordinary specimen area to determine the signal transmission period of the timing signal transmission module;

[0087] When the data analysis unit is in the third specimen placement state, it analyzes the number of specimens placed in the urgent specimen area and the number of specimens placed in the ordinary specimen area to determine the signal transmission period of the timing signal transmission module.

[0088] Specifically, the single-instruction influence state refers to the influence of each individual instruction in the system on the state. In this case, the analysis is relatively simple because only the execution cycle, timing, and specific changes to the system state of a single instruction need to be considered. The composite-instruction influence state involves the interaction of multiple instructions or the situation where a sequence of instructions jointly affects the system state. At this time, the dependency relationships between instructions, conflicts during concurrent execution, and timing superposition effects need to be considered.

[0089] In this embodiment, the data analysis unit sets the first specimen placement state and the second specimen placement state as single-instruction influence states, and sets the three-specimen placement state as a composite-instruction influence state

[0090] The organic combination of the two instruction states not only ensures the speed of data analysis but also takes into account the accuracy in complex situations.

[0091] Specifically, when determining the signal transmission period interval in the single-instruction influence state, it includes,

[0092] In the process of analyzing the number of specimens in the first specimen placement state, the number of specimens placed in the urgent specimen area is determined through the data information detected by the first gravity sensor 2, and the signal transmission period is calculated by the timing signal transmission module according to the number of specimens;

[0093] When the number of specimens detected in the urgent specimen area is N, the basic signal transmission period is T1, and the signal transmission period T01 is calculated, T01 = T1 - N×K1 - K2, where K1 is the first calculation compensation parameter for the number of specimens in the urgent specimen area to calculate the signal transmission period, and K2 is the second calculation compensation parameter for the number of specimens in the urgent specimen area to calculate the signal transmission period;

[0094] When the detected number of specimens increases, the calculated value of the signal transmission period decreases.

[0095] For different numbers of specimens N, the values of K1 and K2 are different,

[0096] In this embodiment, it is set that

[0097] When N ≤ 2, K1 = 0, K2 = 0;

[0098] When 2 < N ≤ 7, K1 = 0.5, K2 = 0;

[0099] When N > 7, K1 = 0, K2 = 4.

[0100] When there are only specimens in the urgent specimen area, the calculation signal sending period is determined according to the number of specimens. Since the specimens stored in the urgent specimen area are all reagents for urgent detection, the more urgent specimens there are, the smaller the calculation signal sending period. At the same time, to ensure operability, the minimum value of the calculation signal sending period is limited for the case where there are only specimens in the urgent specimen area, ensuring that the urgent specimens can be detected as soon as possible while meeting the actual detection requirements.

[0101] Set the calculation signal sending period T01 as the initial urgent sending cycle interval.

[0102] When the specimen sampling is completed, the value of the initial urgent sending cycle interval is re-determined according to the specimen sampling time and the number of signal transmissions.

[0103] Set that the duration from the first sampling signal sent to the specimen being taken away is Tq, and the number of signals sent during this period is m. The data analysis unit analyzes the duration Tq and the number m;

[0104] There is a basic sampling duration TP and a basic signal sending number MP set in the data analysis unit

[0105] If Tq ≤ TP and m ≤ MP, it is determined that the initial urgent sending cycle interval does not need to be adjusted.

[0106] If Tq > TP or m > MP, it is determined that the initial urgent sending cycle interval needs to be adjusted.

[0107] Set the adjusted initial urgent sending cycle interval as T01'.

[0108] When only Tq > TP, set T01 z = T01 - (Tq - TP) × w1;

[0109] When only m > MP, set T01 z = T01 - (m - MP) × w2;

[0110] When Tq > TP and m > MP, set T01 z = T01 - 0.6(Tq - TP) × w1 - (m - MP) × w2;

[0111] Among them, T01 z is the theoretical calculated value of the initial urgent sending cycle interval, w1 is the calculation compensation parameter of the sampling timeout for the initial urgent sending cycle interval, and w2 is the calculation compensation parameter of the sampling over - times for the initial urgent sending cycle interval.

[0112] The minimum value T01X of the initial urgent sending cycle interval is set in the data analysis unit;

[0113] If T01X < T01 z, then set T01’ = T01 z;

[0114] If T01X ≥ T01 z, then set T01’ = T01X.

[0115] In this embodiment, w1 is set to 0.1 and w2 is set to 0.2;

[0116] When there are specimens in the urgent specimen area, it indicates that the cycle interval for specimen detection is relatively urgent. At this time, by recording and analyzing the storage duration of the specimens taken away and the number of sending signals, it is determined whether the specimens taken away meet the urgent requirements. For a small number of urgent specimens, the cycle interval of signal sending is large, so it is evaluated by the storage duration. For a large number of specimens, on the one hand, the detection urgency of many specimens is higher, and on the other hand, the cycle interval of their signal sending is shorter, so it is evaluated by the number of signal sendings. Different evaluation methods can correspond to different specimen storage quantities, and can more intuitively and comprehensively determine whether the storage duration of the specimens is reasonable when the specimens are taken away, and reduce and adjust the initial urgent sending cycle interval according to the determination result. By increasing the signal sending frequency, it urges the specimens to be taken out as soon as possible. At the same time, for those that do not meet the preset requirements in both the storage duration and the number of sending signals, a dual - stimulus is used to reduce the signal sending cycle interval to make the urging more urgent. For those that do not meet the preset requirements in both the storage duration and the number of sending signals, since the number of sendings is directly related to the storage duration, that is, for a long storage duration, the number of sendings will increase appropriately. Therefore, the influence of the storage duration on the output result is adaptively reduced to ensure the accuracy of data calculation. By presetting the minimum cycle interval value, it is possible to prevent the phenomenon of data chaos and the calculated time being unable to be achieved. At the same time, considering the actual situation, when the frequent sending reaches a certain level, the storage duration will not continue to decrease. Therefore, setting the minimum cycle interval value can better complete the supervision of sampling while maintaining the stability of system operation.

[0117] The process of analyzing the number of specimens in the second specimen placement state is to determine the number of specimens placed in the ordinary specimen area through the data information detected by the second gravity sensor 4, and determine the calculation signal sending cycle of the timing signal sending module according to the number of specimens;

[0118] The number of specimens detected in the ordinary specimen area is S, and the basic signal transmission period is T2. Calculate the signal transmission period T02, where T02 = T2 - S×P1 - P2. Here, P1 is the first calculation compensation parameter of the number of ordinary specimens for calculating the signal transmission period, and P2 is the second calculation compensation parameter of the number of ordinary specimens for calculating the signal transmission period;

[0119] When the detected number of specimens increases, the value of the calculated signal transmission period decreases.

[0120] For different specimen numbers S, the values of P1 and P2 are different.

[0121] In this embodiment, it is set that T02 = 30 min.

[0122] When S ≤ 2, P1 = 0, P2 = 0;

[0123] When 2 < S ≤ 7, P1 = 1.5, P2 = 0;

[0124] When S > 7, P1 = 0, P2 = 13.

[0125] When only the ordinary specimen area stores specimens, the calculated signal transmission period is determined according to the number of specimens. Since the specimens stored in the ordinary specimen area are all reagents for ordinary detection, the more ordinary specimens stored, the smaller the calculated signal transmission period. At the same time, to ensure operability, the minimum value of the calculated signal transmission period is limited for the case where only the ordinary specimen area stores specimens, which ensures that ordinary specimens can be detected as soon as possible while meeting the actual detection requirements.

[0126] Set the calculated signal transmission period T02 as the initial ordinary transmission period interval.

[0127] When the specimen sampling is completed, the value of the initial ordinary transmission period interval is re - determined according to the specimen sampling time and the number of signal transmissions.

[0128] Set that the duration from the first sampling signal sent to the specimen being taken away is Rq, and the number of signals sent during this period is l. The data analysis unit analyzes the duration Rq and the number l.

[0129] The basic sampling duration RP and the basic signal transmission number LP are set in the data analysis unit.

[0130] If Rq ≤ RP and l ≤ LP, it is determined that the initial ordinary transmission period interval does not need to be adjusted.

[0131] If Rq > RP or l > LP, it is determined that the initial ordinary transmission period interval needs to be adjusted.

[0132] Set the initial normal transmission cycle interval after adjustment as T02'.

[0133] When only Rq > RP, set T02z = T02 - (Rq - RP) × a1;

[0134] When only l > LP, set T02z = T02 - (l - LP) × a2;

[0135] When Rq > RP and l > LP, set T02z = T02 - 0.6(Rq - RP) × a1 - (l - LP) × a2;

[0136] Wherein, T02z is the calculated theoretical value of the initial normal transmission cycle interval, a1 is the calculation compensation parameter of the sampling timeout for the initial normal transmission cycle interval, and a2 is the calculation compensation parameter of the sampling over - times for the initial normal transmission cycle interval.

[0137] The minimum value T02X of the initial normal transmission cycle interval is set in the data analysis unit;

[0138] If T02X < T02z, then set T02' = T02z;

[0139] If T02X ≥ T02z, then set T02' = T02X.

[0140] In this embodiment, set a1 as 0.03 and set a2 as 0.2;

[0141] When there are only specimens in the normal specimen area, determine the calculation signal transmission cycle according to the number of specimens. Since the specimens stored in the normal specimen area are all reagents for normal detection, the more normal specimens there are, the smaller the calculation signal transmission cycle. At the same time, to ensure operability, the minimum value of the calculation signal transmission cycle is limited for the case where there are only specimens in the urgent specimen area, which ensures that normal specimens can be detected as soon as possible while meeting the actual detection requirements.

[0142] By recording and analyzing the storage duration when the specimen is taken away and the number of transmitted signals, it is determined whether the specimen meets the urgent requirements when it is taken away. For ordinary specimens with a small quantity, the interval between signal transmissions is relatively large, so the evaluation is carried out through the storage duration. For specimens with a large quantity, on the one hand, the detection urgency of numerous specimens is higher, and on the other hand, the interval between signal transmissions is shorter, so the evaluation is carried out through the number of signal transmissions. Different evaluation methods can correspond to different quantities of specimen storage, and can more intuitively and comprehensively determine whether the storage duration of the specimen is reasonable when it is taken away. And the initial ordinary transmission interval is adjusted to be reduced by the judgment result, and by increasing the signal transmission frequency, the specimen is urged to be taken out as soon as possible. At the same time, for those where both the storage duration and the number of transmitted signals do not meet the preset requirements, the signal transmission interval is reduced by double stimulation to make the urging more urgent. For those where both the storage duration and the number of transmitted signals do not meet the preset requirements, since there is a direct relationship between the number of transmissions and the storage duration, that is, the longer the storage duration, the appropriate increase in the number of transmissions. Therefore, the influence of the storage duration on the output result is adaptively reduced to ensure the accuracy of data calculation. By presetting the minimum interval value, it is possible to prevent the phenomenon of data chaos and the inability to achieve the calculated time. At the same time, considering the actual situation, when the frequent transmissions reach a certain level, the storage duration will not continue to decrease. Therefore, setting the minimum interval value can better complete the urging of sampling while maintaining the stability of the system operation.

[0143] Specifically, when calculating the signal transmission cycle under the influence of the composite order, it includes,

[0144] The process of analyzing the number of specimens in the third specimen placement state is as follows: the number of specimens placed in the urgent specimen area is determined through the data information detected by the first gravity sensor 2, the number of specimens placed in the ordinary specimen area is determined through the data information detected by the second gravity sensor 4, and the calculation signal transmission cycle of the signal transmission module is determined by calculating the signal transmission cycle compensation for the urgent specimen area through the compensation coefficient;

[0145] The composite calculated signal transmission cycle is T03, T03 = (T1 - N × K1 - K2) - Z, where Z is the compensation parameter for calculating the signal transmission cycle of the urgent specimen area due to the capacity limit;

[0146] When N ≤ 12 and S ≤ 12, Z = 0;

[0147] When N > 12 or S > 12, Z = 3.

[0148] When both ordinary specimens and urgent specimens are stored, the total number of specimens is counted. In this embodiment, when the total number of specimens on any layer is less than 12, the sampling period interval of ordinary specimens is always greater than that of urgent specimens. Therefore, the interference of ordinary specimens is not considered. When the number of specimens is greater than or equal to 12, the capacity of the upper or lower specimen area is close to the limit, and the information sending period is further reduced.

[0149] Set the composite calculation signal sending period T03 as the initial composite sending period interval.

[0150] When the specimen sampling is completed, the value of the initial composite sending period interval is re-determined according to the specimen sampling time and the number of signal transmissions.

[0151] Set that the time duration from the first sampling signal sent to the specimen being taken away is Bq, and the number of signals sent during this period is d. The data analysis unit analyzes the time duration Bq and the number of times d.

[0152] The data analysis unit is provided with a basic sampling time duration BP and a basic signal sending number DP.

[0153] If Bq ≤ BP and d ≤ DP, it is determined that the initial composite sending period interval does not need to be adjusted.

[0154] If Bq > BP or d > DP, it is determined that the initial composite sending period interval needs to be adjusted.

[0155] Set the adjusted initial composite sending period interval as T03'.

[0156] When only Bq > BP, set T03z = T03 - (Bq - BP) × e1;

[0157] When only d > DP, set T03z = T03 - (d - DP) × e2;

[0158] When Bq > BP and d > DP, set T03z = T03 - 0.6 × (Bq - BP) × e1 - (d - DP) × e2;

[0159] Among them, T03z is the calculated theoretical value of the initial composite sending period interval, e1 is the calculation compensation parameter for the sampling timeout to the initial composite sending period interval, and e2 is the calculation compensation parameter for the sampling overnumber to the initial composite sending period interval.

[0160] The data analysis unit is provided with the minimum value T03X of the initial composite sending period interval.

[0161] If T03X < T03z, set T03' = T03z;

[0162] If T03X ≥ T03z, then set T03’ = T03X.

[0163] In this embodiment, set e1 to 0.1 and set e2 to 0.2;

[0164] When there are specimens in both the ordinary specimen area and the urgent specimen area, by recording and analyzing the storage duration of the specimens being taken away and the number of signal transmissions, it is determined whether the specimens being taken away meet the urgent requirements. For a relatively small total number of specimens, the interval between signal transmissions is relatively large, so the storage duration is used for evaluation. For areas with a large number of specimens, on the one hand, the detection urgency of many specimens is higher, and on the other hand, the interval between signal transmissions is shorter, so the number of signal transmissions is used for evaluation. Different evaluation methods can correspond to different specimen storage quantities, and can more intuitively and comprehensively determine whether the storage duration of the specimens is reasonable when the specimens are taken away. And through the determination result, the initial composite transmission interval is adjusted to be reduced, and by increasing the signal transmission frequency, the specimens are urged to be taken out as soon as possible. At the same time, for those where both the storage duration and the number of signal transmissions do not meet the preset requirements, double stimulation reduces the signal transmission interval, making the urging more urgent. For those where both the storage duration and the number of signal transmissions do not meet the preset requirements, since the number of transmissions is directly related to the storage duration, that is, for longer storage durations, the number of transmissions will increase appropriately. Therefore, the influence of the adaptive reduction of the storage duration on the output result is reduced to ensure the accuracy of data calculation. By presetting the minimum interval value, the phenomenon of data chaos and the inability to achieve the calculated time is prevented. At the same time, considering the actual situation, when the frequent transmissions reach a certain level, the storage duration will not continue to decrease. Therefore, setting the minimum interval value can better complete the urging of sampling while maintaining the stability of system operation.

[0165] The data analysis unit monitors the status of the specimens in real time and transmits it to the corresponding working modules, and adopts differential management for different specimen placement situations, greatly reducing the manual transportation cost of specimen submission, realizing the status tracking of specimens, ensuring the priority processing of urgent specimens, and improving the management efficiency.

[0166] Specifically, the data analysis unit also has the task of determining the alarm time.

[0167] When there is an urgent specimen in the specimen rack, the standard alarm time H1 is 35 min, and the calculated alarm time is H01. Alarm time H01 = H1 - N × Q1 - Q2, where Q1 is the first compensation value of the number of specimens in the urgent area for the alarm time, and Q2 is the second compensation value of the number of specimens in the urgent area for the alarm time.

[0168] N > 7, Q1 = 2, Q2 = 0

[0169] N ≤ 7, Q1 = 0, Q2 = 15

[0170] When there are urgent specimens and there are specimens in the general specimen area in the specimen rack, the alarm time H2 is 120 min, and the calculated alarm time is H02, H02 = H2 - N × u1 - u2, where u1 is the first compensation value of the number of specimens in the general area for the alarm time, and u2 is the second compensation value of the number of specimens in the general area for the alarm time.

[0171] S > 7, u1 = 7, u2 = 0

[0172] S ≤ 7, u1 = 0, u2 = 55

[0173] Because the specimens in the urgent area require shorter processing time, when there are specimens in the urgent specimen area, the alarm time calculated for the urgent specimen area is used as the actual alarm time. When there are no specimens in the urgent area, the influence of the urgent area does not need to be considered, and the time calculated for the general specimen area is used as the actual alarm time. On the one hand, the more specimens there are, the more urgent the capacity of the specimen rack is, and the corresponding alarm time will be shortened. On the other hand, the more specimens there are, the greater the possibility of cross - contamination between specimens, and the alarm time also needs to be shortened accordingly to ensure the reliability of the specimen submission process. By presetting the minimum alarm time, it is possible to prevent the phenomenon of data chaos and the inability to implement the calculated time. At the same time, considering the actual situation, an overly short alarm time will also interfere with other staff and affect the medical treatment environment of the hospital.
