Description

  The present invention relates to a consumable management system that manages reagents used by an automatic analyzer that analyzes various components contained in, for example, blood and urine of a patient.

  As an automatic analyzer, a biochemical analyzer that analyzes various components contained in a specimen such as blood and urine is known. In this biochemical analyzer, samples such as serum and urine are diluted under certain conditions, then dispensed into a reaction vessel, and a reagent according to the analysis item and the sample are mixed in the reaction vessel (cuvette). To react. The biochemical analyzer analyzes the measurement target substance contained in the sample by measuring the absorbance of the diluted sample dispensed in the reaction container and converting the absorbance into a concentration.

In a medical institution where a large number of patients visit, it is important to manage how many tests are performed in advance and how much reagent is required. Here, with reference to FIG. 6, a conventional method for determining the remaining amount of reagent will be described.
FIG. 6 shows a configuration example of a conventional automatic analyzer 100. It is assumed that the automatic analyzer 100 determines the remaining reagent amount before the routine. In the following description, an inspection work performed by an inspection engineer in a medical institution such as a hospital is referred to as a “routine”.

The automatic analyzer 100 includes a current reagent amount storage unit 101, an operation unit 102, a scheduled analysis number storage unit 103, a determination unit 104, and a determination result display unit 105.
The current reagent amount storage unit 101 stores the reagent remaining amount of the reagent currently set in the automatic analyzer 100 for each reagent type.
The operation unit 102 is operated by an inspection engineer and writes the planned number of analyzes to be performed on the day to the planned analysis number storage unit 103.
The scheduled analysis number storage unit 103 stores the scheduled analysis number of the day written by the operation unit 102.

The determination unit 104 calculates the reagent amount necessary for the inspection from the planned analysis number read from the planned analysis number storage unit 103. Then, the determination unit 104 compares the current reagent amount read from the current reagent amount storage unit 101 with the calculated reagent amount to determine whether or not the reagent currently set in the automatic analyzer 100 is insufficient. .
The determination result display unit 105 displays the determination result by the determination unit 104.

  As described above, in the conventional automatic analyzer 100, the excess or deficiency of the reagent amount required on the inspection day is determined based on the planned number of analyzes input by operating the operation unit 102 by the inspection engineer. However, mistakes may occur in operations in which a reagent is prepared based on the rule of thumb of a laboratory technician or the laboratory technician monitors the remaining amount of reagent. For this reason, it has been studied to avoid the shortage of reagents by the technique disclosed in Patent Document 1.

  Japanese Patent Laid-Open No. 2004-151867 describes that “the amount of reagent necessary for future measurement is calculated based on past reagent information and the remaining amount of detected reagent, and the lack of the amount of reagent mounted in the analyzer is determined. In addition, the amount of reagent shortage is calculated, and the amount of reagent necessary for future measurement and the amount of reagent shortage are displayed. In the apparatus disclosed in Patent Document 1, it is assumed that the measurement results can be easily grasped by calculating, for example, every day of the week, season, and time, and a certain degree of error can be absorbed by setting a margin. ing.

Japanese Patent No. 3610345

  However, in the technique disclosed in Patent Document 1, the actual number of measurements in the past predetermined period is used as the expected number of analyses. In an environment where clinical tests are performed, it has been difficult to pattern variations in the number of analyzes on days of the week and seasons. For example, regardless of the day of the week or the season, there was a pattern that the number of outpatients increased at the end of consecutive holidays, and the number of specific examination items increased on the day when mass screening was performed.

  In order to suppress the influence of various patterns on the test, the automatic analyzer can hold many types of measurement results and allow the inspection engineer to select the pattern, or set a large margin for the remaining amount of reagent. It is necessary to keep. However, the pattern only reflects past results, and even if a margin for the remaining amount of the reagent is provided, a situation in which there is a shortage of reagents cannot be avoided if there are a large number of inspection items on the day. In this case, the report of the test result to the medical staff who requested the test is delayed, and the report of the test result to the patient is also delayed.

  The present invention has been made in view of such a situation, and an object thereof is to prevent a consumable item from running out during a routine.

The present invention includes an ordering system, a clinical examination system, and an automatic analyzer.
The clinical test system sends the planned number of analyzes calculated for each test item based on the test order input from the ordering system to the automatic analyzer, receives the analysis results from the automatic analyzer,
The automatic analyzer calculates the amount of consumables used in the analysis based on the planned number of analyzes acquired from the clinical inspection system, outputs the excess or shortage of consumables, and performs the inspection based on the inspection items. The analysis result obtained is transmitted to the clinical laboratory system.

According to the present invention, the laboratory technician outputs a shortage of consumables because the automatic analyzer outputs an excess or shortage of consumables based on the planned number of analyzes calculated based on the test order received from the ordering system by the clinical test system. The product can be replenished in advance. For this reason, there is no risk of interruption of the inspection during the routine, and the inspection result can be reported quickly.
Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

[1. First Embodiment (Routine Preparation)]
Hereinafter, a reagent management system according to a first embodiment of the present invention will be described with reference to FIGS. The reagent management system according to the first embodiment is used as an example of a consumable management system that determines whether the reagent remaining amount of a reagent (an example of a consumable) set in the automatic analyzer is excessive or insufficient during routine preparation. It is done. In the present specification and drawings, components having substantially the same function or configuration are denoted by the same reference numerals, and redundant description is omitted.

FIG. 1 is a block diagram illustrating a configuration example of the reagent management system 1.
The reagent management system 1 includes an ordering system 2, a LIS (Laboratory Information System) 3, and an automatic analyzer 4.

  The ordering system 2 includes a HIS (Hospital Information System), an electronic medical record, and the like, and is also called a host system. The ordering system 2 accepts an examination order (examination reservation) from a medical worker, and transmits the examination order as a reservation order to the LIS 3 for each patient.

  The LIS 3 is also called a clinical laboratory system, and stores a reservation order received from the ordering system 2. In the inspection work of a hospital, outpatient and inpatient inspection reservations are generally made in advance using the ordering system 2. In addition, the ratio of emergency orders and in-patient orders on the day is not so high in a one-day examination. For this reason, the LIS 3 transmits the planned number of analysis calculated for each inspection item based on the reservation order to the automatic analyzer 4 and receives the analysis result from the automatic analyzer 4. The LIS 3 includes an order acquisition unit 31, a reservation order storage unit 32, an order extraction unit 33, and a communication unit 34.

The order acquisition unit 31 acquires an inspection order periodically transmitted from the ordering system 2. The order acquisition unit 31 can also request the ordering system 2 to acquire a reservation order at an arbitrary timing.
The reservation order storage unit 32 stores the inspection order acquired by the order acquisition unit 31 as a reservation order. The reservation order storage unit 32 is configured by, for example, an HDD (Hard Disk Drive).

The order extraction unit 33 extracts a reservation order corresponding to the inspection performed on the current day by the automatic analyzer 4 from the reservation order storage unit 32, and calculates the planned number of analyzes for each inspection item based on the reservation order.
The communication unit 34 (an example of a first communication unit) transmits the planned number of analyzes calculated by the order extraction unit 33 to the automatic analyzer 4 and receives the analysis result from the automatic analyzer 4.

  The automatic analyzer 4 calculates the amount of reagent used in the analysis based on the planned number of analyzes acquired from the LIS 3, outputs the excess or deficiency of the reagent, and the analysis obtained by performing the inspection based on the inspection item Send the result to LIS3. As the automatic analyzer 4, for example, a biochemical analyzer is used. The automatic analyzer 4 includes a communication unit 41, an operation unit 42, a current reagent amount storage unit 43, a scheduled analysis number storage unit 44, a determination unit 45, and a determination result display unit 46.

The communication unit 41 (an example of a second communication unit) can communicate with the communication unit 34 of the LIS 3, receives the planned number of analysis from the LIS 3, and transmits the analysis result to the LIS 3.
The operation unit 42 is operated by an inspection engineer, and requests the LIS 3 to transmit the planned number of analyzes through the communication unit 41.

The current reagent amount storage unit 43 is used as an example of a consumable amount storage unit that stores the reagent remaining amount of the reagent currently set in the automatic analyzer 4.
The planned analysis number storage unit 44 stores the planned analysis number received by the communication unit 41.

  The determination unit 45 calculates the reagent amount (use amount) required for the examination based on the planned analysis number read from the planned analysis number storage unit 44. Then, the determination unit 45 compares the reagent amount required for the inspection with the current reagent amount read from the current reagent amount storage unit 43, and determines whether the reagent amount is excessive or insufficient for each item used for the inspection. The determination result is output to the determination result display unit 46.

  The determination result display unit 46 is used as an example of a determination result output unit that displays the determination result of the determination unit 45, the current reagent amount, the reagent amount required for the examination acquired from the LIS 3, and the like. And the amount of reagent currently set is less than the amount of reagent required for the test, or the remaining amount of the reagent set after the test of the expected number of analyzes is below the preset threshold In that case, warn the laboratory technician. As a result, the inspection engineer can set a sufficient amount of reagent in the automatic analyzer 4 before the routine in preparation for the inspection.

  FIG. 2 is a configuration diagram of the reservation order management table.

  The reservation order management table includes fields of device name and examination item, and is managed by the reservation order storage unit 32 for each patient (for example, patients (1) and (2)) to be examined. When the name of the automatic analyzer 4 is the device B, it is indicated in the reservation order management table that the examination items of the samples of the patients (1) and (2) analyzed by the device B are e and f.

  Since the reservation order management table is provided for each patient to be examined, when a plurality of patients undergo examinations, the planned number of analyzes handled by the device B is a value obtained by multiplying the number of patients by the number of e and f (for example, If there are 5 patients, 5 × 2 = 10). Then, the order extraction unit 33 extracts the reservation order of the device B from the reservation order storage unit 32 and calculates the planned number of analysis.

<Routine preparation>
FIG. 3 is a sequence diagram showing a processing example of each part of the reagent management system 1 in the routine preparation.

  First, a medical worker inputs an inspection order into the ordering system 2 (S1). After registering the inspection order (S2), the ordering system 2 transmits the inspection order to the LIS 3 (S3). The LIS 3 stores the inspection order received from the ordering system 2 in the reservation order storage unit 32 as a reservation order (S4).

  When performing routine preparation, an inspection engineer operating the automatic analyzer 4 instructs the automatic analyzer 4 to acquire the planned number of analyzes through the operation unit 42 (S5). This instruction is transmitted to the LIS 3 through the communication unit 41 of the automatic analyzer 4 (S6).

  The order extraction unit 33 of the LIS 3 calculates the planned number of analyzes from the reservation order stored in the reservation order storage unit 32 (S7). Then, the communication unit 34 of the LIS 3 transmits the planned number of analyzes to the automatic analyzer 4 (S8).

  The communication unit 41 of the automatic analyzer 4 stores the planned analysis number received from the LIS 3 in the planned analysis number storage unit 44. The determination unit 45 calculates the reagent amount of the required reagent from the planned analysis number read from the planned analysis number storage unit 44. The reagent amount is calculated by multiplying the amount required for each inspection item by the planned number of analyses. Then, the determination unit 45 compares the reagent amount of the required reagent with the reagent remaining amount of the reagent currently set in the automatic analyzer 4 read from the current reagent amount storage unit 43 (S9).

  When the determination result of the determination unit 45 is that the current reagent amount is insufficient, or the remaining amount of the reagent after the analysis of the planned number of analyzes is less than or equal to a preset threshold value (S10), a determination result display A warning is displayed on the unit 46 (S11).

  When the inspection engineer confirms the warning displayed on the determination result display unit 46 (S12), the inspection engineer prepares the missing reagent and replenishes the automatic analyzer 4 with the reagent (S13). When the automatic analyzer 4 detects that the reagent has been replenished, it notifies the laboratory technician that the reagent shortage has been resolved.

  According to the reagent management system 1 according to the first embodiment described above, the automatic analyzer 4 obtains the planned number of analyzes from the LIS 3 to accurately grasp the planned number of analyzes on the day when the routine is performed. In addition, reagents such as reagents can be prepared in advance.

  Conventionally, the number of inspection items is predicted on the same day in the automatic analyzer 4, but the LIS 3 </ b> A communicates with the ordering system 2. Thereby, the automatic analyzer 4 can acquire the number of inspection items at an arbitrary timing or periodically. For this reason, the automatic analyzer 4 can detect a lack of reagents before the sample arrives at the examination room.

  Moreover, since the automatic analyzer 4 periodically obtains the expected number of analyzes from the LIS 3, an inspection engineer or the like does not have to make many settings in advance. For this reason, the setting mistake etc. of the reagent amount set to the automatic analyzer 4 can be reduced.

[2. Second Embodiment (During Routine)]
Next, a reagent management system according to a second embodiment of the present invention will be described with reference to FIG. 4 and FIG. The reagent management system according to the second embodiment is used as an example of a consumable management system in which the automatic analyzer in the routine periodically determines the reagent amount.

FIG. 4 is a block diagram illustrating a configuration example of the reagent management system 1A.
The reagent management system 1A includes an ordering system 2, a LIS 3A, and an automatic analyzer 4.

The LIS 3A has a function equivalent to that of the LIS 3 according to the first embodiment described above, but is different from the LIS 3 in that a fixed order storage unit 35 is provided in addition to the configuration of the LIS 3.
The confirmed order storage unit 35 extracts, from the reserved order storage unit 32, a reservation order that is confirmed to be inspected by the automatic analyzer 4 as a confirmed order. When a sample stored as a reservation order in the reservation order storage unit 32 arrives at the examination room, or when a patient subject to the inspection order is registered at the reception of a hospital or the like, the confirmation order is stored in the confirmation order storage unit 35 Is done.

  The order extraction unit 33 extracts a confirmed order from the confirmed order storage unit 35, and calculates the planned number of analyzes for each inspection item based on the confirmed order. Then, the order extracting unit 33 transmits the planned number of analyzes to the automatic analyzer 4 through the communication unit 34.

  During the routine, the doctor instructs the examination at any time, cancels the examination order, adds or changes the examination, and the number of reservation orders changes in real time. For this reason, there may be a situation where the reagent amount prepared before the routine is insufficient.

  However, the automatic analyzer 4 periodically acquires the planned number of analyzes from the LIS 3A, so that it can be determined during the routine whether the reserved number of analyzes can be analyzed with the current reagent remaining amount. In this method, it is possible to determine whether there is a necessary reagent amount and a lack of reagents at the timing when the reservation order is confirmed. For this reason, even during the routine, the laboratory technician can replenish the reagent with a margin.

<During routine>
FIG. 5 is a sequence diagram showing a processing example of each part of the reagent management system 1A in the routine. Since the processing from step S21 to S24 in FIG. 5 is the same as the processing from step S1 to S4 shown in FIG. 3 described above, detailed description thereof is omitted. The LIS 3A receives a reservation order from the ordering system 2 at any time and stores it in the reservation order storage unit 32.

  The LIS 3A and the automatic analyzer 4 perform a loop process for acquiring the planned number of analyzes (S25). If the automatic analyzer 4 is in the routine, the order acquisition unit 31 of the automatic analyzer 4 periodically requests the LIS 3 to acquire the planned number of analyzes (S26).

  The order extraction unit 33 of the LIS 3A calculates the planned number of analyzes from the confirmed order stored in the confirmed order storage unit 35 (S27), and the communication unit 34 of the LIS 3A transmits the confirmed number of analyzes confirmed to the automatic analyzer 4. (S28). Since the subsequent processing from step S29 to S33 is the same as the processing from step S10 to S13 shown in FIG. 3 described above, detailed description thereof is omitted.

  According to the reagent management system 1A according to the second embodiment described above, the automatic analyzer 4 obtains the scheduled number of analyzes from the LIS 3A as needed, thereby accurately grasping the number of inspection items during the routine, It becomes possible to prepare reagents in advance.

[3. Modified example]
Note that the determination unit 45 gives an instruction to increase the number of reagents set in the automatic analyzer 4 if the test requires more reagents than usual. In this case, since the determination result display unit 46 displays which reagent to increase, the laboratory technician can set more reagents than usual in the automatic analyzer 4.

  In addition, the automatic analyzer 4 is an automatic analyzer 4 connected to the LIS 3 or 3A linked to the ordering system 2 in order to predict the necessary amount of reagent based on information managed by the LIS 3 or 3A. For example, any automatic analyzer 4 can be realized. For example, it can be used in an automatic analyzer 4 such as a blood count measurement device or an immunoassay device.

  In addition, a field indicating a confirmed order is provided in the reserved order storage unit 32 according to the second embodiment, and a flag indicating the presence / absence of a confirmed order is written in this field to identify the confirmed order from the reserved order. Is possible. In this case, the confirmed order storage unit 35 becomes unnecessary from the LIS 3A.

Further, the consumable item is not limited to a reagent, but also includes a test paper.
Further, instead of the determination result display unit 46, the automatic analyzer 4 may be provided with a speaker that emits a message requesting reagent replenishment as an example of the determination result output unit.
