As shown in FIG. 5, the urine (sample) in the test tube 32 is aspirated by a syringe pump (not shown) using an aspirate tube 17, and dispensed into the sample preparing unit 2 by the sample distributing part 1. The sample preparing unit according to the present embodiment is configured by a sample preparing part (first sample preparing part) 2u and a sample preparing part (second sample preparing part) 2b, and the sample distributing part 1 distributes the quantitated aliquot of the urine (sample) to each of the sample preparing part 2u and the sample preparing part 2b.
The urine aliquot of the sample preparing part 2u is mixed with a diluted solution 69u and a stain solution (stain reagent) 68u. The urine aliquot of the sample preparing part 2u is then stained by the pigment contained in the stain solution (stain reagent) 68u, so that the urine aliquot becomes a suspension for analyzing a relatively large particles such as red blood cells, white blood cells, epidermal cells, casts, and the like. The urine aliquot of the sample preparing part 2b, on the other hand, is mixed with a diluted solution 69b and a stain solution (stain reagent) 68b. The urine aliquot of the sample preparing part 2b is then stained by the pigment contained in the stain solution (stain reagent) 68b, so that the urine aliquot becomes a suspension for analyzing bacteria.
Of the two types of suspensions (measurement samples) prepared as above, the suspension (first measurement sample) of the sample preparing part 2u is first guided to the optical detector 3 forming a thin flow enveloped by sheath solution in a sheath flow cell 51, and irradiated with laser light.

As shown in FIG. 1, the transporting apparatus 11 is connected to the front part of the apparatus body 12 of the analyzer 10. The transporting apparatus 11 has a function of transporting a plurality of test tubes (sample containers) 32 held in the rack 31 to the aspirating position facing the sample aspirating part 10a of the analyzer 10 to supply the sample to the analyzer 10. The rack 31 is held with the plurality of test tubes 32 lined in one row.
As shown in FIG. 7, a rack set region 34 for setting the rack 31 holding the test tube 32 in which a non-processed sample is accommodated is arranged on the right side of the transporting apparatus 11, and a rack accommodating region 35 for accommodating the rack 31 holding the test tube 32 in which the processed sample is accommodated is arranged on the left side of the transporting apparatus 11. A transport path 34c is formed between a terminating position 34b of the rack set region 34 and a starting position 35a of the rack accommodating region.
The plurality of racks 31 having the longitudinal direction directed in the left and right direction can be arranged in the front and back direction in the rack set region 34 and the rack accommodating region 35. In the rack set region 34, each rack 31 is transported from the starting position 34a on the near side towards the terminating position 34b on the back side as shown with an arrow (1), and thereafter, transported towards the left (direction of arrow (2)) on the transport path 34c towards the starting position 35a of the rack accommodating region 35. The central part of the transport path 34c is the aspirating position of the sample aspirating part 10a. The aspirating position is a position facing the sample aspirating part 10a. Each test tube 32 is sequentially arranged facing the sample aspirating part 10a of the analyzer 10 while transporting the rack 31 towards the left on the transport path 34c. The sample is aspirated from the test tube 32 of the rack 31 arranged at the aspirating position by the sample aspirating part 10a. After aspiration is terminated, the test tube 32 adjacent to the test tube 32, which sample has been aspirated, is then arranged at the aspirating position, and the sample of the test tube 32 arranged at the aspirating position is aspirated. The rack 31 is transported to the starting position 35a of the rack accommodating region 35 when the aspiration of the sample from all the test tubes 32 accommodated in the rack 31 is terminated by repeating such operation. The rack 31 transported to the starting position 35a is transported towards the terminating position 35b on the near side as shown with an arrow (3). In this manner, all the racks 31 set in the rack set region 34 are accommodated in the rack accommodating region 35 when aspiration of the sample from all the test tubes 32 accommodated in the rack 31 is terminated.
The transporting apparatus 11 has a plurality of types depending on the size etc. of the rack 31 to be transported. FIGS. 8(a) and 8(b) show transporting apparatuses 11X and 11W for transporting two types of racks 31 in which the number of test tubes 32 that can be held differs. The transporting apparatus 11X (hereinafter referred to as transporting apparatus X) of FIG. 8(a) is for the rack 31 (for ten-sample rack) for holding ten test tubes 32, and the transporting apparatus 11W (hereinafter referred to as transporting apparatus W) of FIG. 8(b) is for the rack 31 (for five-sample rack) for holding five test tubes 32.
The ten-sample rack used in the transporting apparatus X and the five-sample rack used in the transporting apparatus W will now be described. As shown in FIG. 9(a), the ten-sample rack 226 includes ten accommodating parts 211 for accommodating the test tube 32. As shown in FIG. 9(b), the ten-sample rack 226 includes ten concave parts 212 at the bottom surface. Each concave part 212 is arranged at a position corresponding to each accommodating part 211. As shown in FIG. 10, the five-sample rack 92 includes five accommodating parts 93 for accommodating the test tube 32 and one concave part 96 arranged at the center in the longitudinal direction of the bottom surface. The interval at which the accommodating position for accommodating the test tube 32 is arranged differs between the ten-sample rack 226 and the five-sample rack 92. That is, the distance T1 between the test tubes 32 accommodated in the accommodating part 211 of the ten-sample rack 226 and the distance T2 between the test tubes 32 accommodated in the accommodating part 93 of the five-sample rack 92 differ.
The transverse feeding operation for feeding the test tube 32 accommodated in the ten-sample rack 226 of the transporting apparatus X to the aspirating position facing the sample aspirating part 10a will now be described. The transporting apparatus X includes a projection for engaging the concave part 212 of the ten-sample rack 226, a slide mechanism for moving the projection, and a stepping motor for driving the slide mechanism (not shown). The transporting apparatus X is formed with a transport surface for transporting the ten-sample rack 226, so that the ten-sample rack 226 moves on the transport surface. A cutout for projecting the projection is formed at the transport surface. The projection is at an initial position of the lower part of the transport surface adjacent to the cutout. The projection moves from the initial position and projects out from the cutout when the stepping motor is operated. The projected projection engages one of the ten concave parts 212 arranged at the bottom surface of the ten-sample rack 226, and the projection horizontally moves and feeds the ten-sample rack 226 transversely by one pitch when the stepping motor is operated. The transporting apparatus X also provides a pulse signal of the number of pulse for feeding one pitch to the stepping motor in accordance with the distance T1 between the test tubes 32 of the rack 226, whereby the rack 226 is fed by one pitch. When the test tube 32 is transported to the aspirating position facing the sample aspirating part 10a, the sensor 37a detects such transport and transmits a detection signal to the measurement control unit 16 (see FIG. 3). The test tube 32 is then arranged at the aspirating position. The projection is then disengaged from the concave part 212, and returned to the initial position by operating the stepping motor. The projection then engages the adjacent concave part 21 of the previously engaged concave part 212, and the projection horizontally moves and feeds the ten-sample rack 226 transversely by one pitch when the stepping motor is operated.
The transverse feeding operation for feeding the test tube 32 accommodated in the five-sample rack 92 of the transporting apparatus W (FIG. 8(b)) to the aspirating position facing the sample aspirating part 10a will now be described. The transporting apparatus W includes a projection for engaging the concave part 96 of the five-sample rack 92, a movement belt for moving the projection, and a stepping motor for driving the movement belt (not shown). The transporting apparatus W is formed with a transport surface for transporting the five-sample rack 92, so that the five-sample rack 92 moves on the transport surface. A cutout for projecting the projection is formed at the transport surface. The projection is at an initial position of the lower part of the transport surface adjacent to the cutout. The projection moves from the initial position and projects out from the cutout when the stepping motor is operated. The projection engages one concave part 96 arranged at the bottom surface of the five-sample rack 92, and the projection horizontally moves and feeds the five-sample rack 92 transversely by one pitch when the stepping motor is operated. The transporting apparatus W also provides the number of pulse for feeding one pitch to the pulse motor in accordance with the distance T2 between the test tubes 32 of the rack 92, whereby the rack 92 is fed by one pitch. When the test tube 32 is transported to the aspirating position facing the sample aspirating part 10a, the sensor 37a detects such transport and transmits a detection signal to the measurement control unit 16 (see FIG. 3). The test tube 32 is then arranged at the aspirating position. When the stepping motor is operated while engaging the one concave part 96 arranged at the bottom surface of the five-sample rack 92, the projection horizontally moves and feeds the five-sample rack 92 transversely by one pitch. The projection is then disengaged from the concave part 96 when the five-sample rack 92 is fed by five pitches, and returned to the initial position by operating the stepping motor. The projection then engages the concave part 96 of the adjacent five-sample rack 92 of the five-sample rack 92 that has been transversely fed by five pitches, and horizontally moves and feeds the five-sample rack 92 transversely by one pitch when the stepping motor is operated.
As shown in FIG. 8, the transporting apparatus X for the ten-sample rack and the transporting apparatus W for the five-sample rack have substantially the same left-right width so as to correspond to the left-right width of the apparatus body 12 of the analyzer 10, but differs in the length in the front and back direction. The ten-sample rack transporting apparatus X and the five-sample rack transporting apparatus W differ in the transporting distance L11 and L12 of the rack 31 in the rack set region 34 and the rack accommodating region 35, and furthermore, the rack transporting distances L21 and L22 between the rack set region 34 and the rack accommodating region 35 as well as the feeding pitches P1 and P2 for feeding each test tube 32 to the aspirating position facing the sample aspirating part 10a differ. As described above, the mechanism and the operation for transverse feeding each test tube 32 to the aspirating position differ between the transporting apparatuses X, W. Therefore, programs for operation controlling the transporting apparatuses X, W differ from each other.
The transporting apparatus 11 also has a plurality of types depending on whether or not a control unit for controlling the operation thereof is arranged. As shown in FIG. 3, the transporting apparatuses X, W described above include a transport driving part 36a such as a stepping motor for transporting the rack 31 and a sensor 37a such as a photosensor and a microswitch for detecting the position etc. of the rack 31 but do not include a control unit. Thus a transporting apparatus X controlling program and a transporting apparatus W controlling program are incorporated in the memory 21 to control the transporting apparatuses X, W from the measurement control unit 16 of the analyzer 10.
When the transporting apparatus controlling program is executed, the signal from the transport sensor 37a is transmitted to the microprocessor 20 of the measurement control unit 16 via the sensor signal processing part 23 and the I/O controller 22. When the signal is transmitted, the microprocessor 20 transmits information for control to the driving unit control driver 24 via the I/O controller 22. The driving unit control driver 24 generates a control signal corresponding to the transmitted information, and transmits the control signal to the transport driving part 36a to perform the control. Therefore, communication of the sensor signal and the control signal is performed between the measurement control unit 16 and the transporting apparatuses X, W.
The procedure for the communication between the measurement control unit 16 and the transporting apparatus X (ten-sample rack transporting apparatus) will now be specifically described with reference to FIG. 11. The microprocessor 20 (FIG. 3) of the measurement control unit 16 executes the transporting apparatus X program stored in the memory 21. The microprocessor 20 provides information such as rotation amount, rotating direction, speed, and the like of the pulse motor for horizontally moving (transverse feeding) the projection for transporting the ten-sample rack 226 to the driving unit control driver 24. The driving unit control driver 24 transmits the control signal to the transport driving part 36a according to the received information. The transporting apparatus X receives the control signal, so that the transport driving part 36a operates according to the control signal, and the ten-sample rack 226 is transported (transversely fed) so that the test tube 32 at the head of the ten-sample rack 226 is at the aspirating position facing the sample aspirating part 10a. The sensor 37a of the transporting apparatus X detects that the head test tube 32 has been transported to the aspirating position facing the sample aspirating part 10a, and the detection signal is provided to the microprocessor 20 via the sensor signal processing part 23. The microprocessor 20 then controls the sample aspirating part 10a so that the sample is aspirated from the test tube 32. The sample aspirating part 10a then aspirates the sample from the test tube 32. When aspiration is terminated, the microprocessor 20 sends information such as rotation amount, rotating direction, speed, and the like of the pulse motor for performing the returning operation of returning the projection for transporting the ten-sample rack 226 to the initial position to the driving unit control driver 24. The driving unit control driver 24 transmits the control signal to the transport driving part 36a according to the received information. The transporting apparatus X receives the control signal, so that the transport driving part 36a operates according to the control signal and the projection is returned to the initial position. Such procedure is repeatedly carried out for all the test tubes 32 accommodated in the ten-sample rack 226.
The configuration of transporting apparatuses Y, Z will now be described. As shown in FIG. 3, the transporting apparatuses Y, Z include a transport driving part 36b and a transport sensor 37b. The transporting apparatuses Y, Z also include a control unit 38. The control unit 38 is arranged with an external communication controller 39, a microprocessor 40, and a memory 41. The external communication controller 39 is connected to the external communication controller 25 of the analyzer 10. When the transporting apparatuses Y, Z are connected, a communication program for communicating with the control units 38 of the transporting apparatuses Y, Z is executed in the measurement control unit 16 of the analyzer 10 to achieve cooperation of operation with the transporting apparatuses Y, Z. The transporting apparatuses Y, Z is generally used as one part of a transport system used for a plurality of analyzers in a large facility etc. The transport driving part 36b is operation controlled by a control program incorporated in the memory 41 of the control unit 38.
When the transporting apparatuses Y, Z are connected to the analyzer 10, the communication is performed in the following manner. For example, when the transporting apparatus Y, Z transports the test tube 32 to the aspirating position facing the sample aspirating part 10a, the information indicating the same is transmitted to the analyzer 10, and the analyzer 10 receives such information and performs the operation of aspirating the sample from the test tube 32. Subsequently, the analyzer 10 transmits information indicating that the sample has been aspirated to the transporting apparatus Y, Z, and the transporting apparatus Y, Z receives such information and performs the operation of transporting the next test tube 32 to the aspirating position facing the sample aspirating part 10a.
The procedure for communication between the transporting apparatus Y (ten-sample rack transporting apparatus) and the analyzer 10 will now be specifically described with reference to FIG. 12. The microprocessor 40 of the transporting apparatus Y executes the control program for controlling the operation of the transporting apparatus Y, and the microprocessor 20 of the apparatus body 12 executes the communication program for performing communication of the analyzer 10 and the transporting apparatus Y and the control program for controlling the operation of the analyzer 10. The microprocessor 40 of the transporting apparatus Y transports (feeds transversely) the ten sample rack 226 so that the head test tube 32 of the sample rack 226 comes to the aspirating position facing the sample aspirating part 10a. The microprocessor 40 sends a measurement instruction signal instructing the start of measurement of the apparatus body 12 (or transport terminated signal indicating that transport is terminated) to the measurement control unit 16 of the analyzer 10. The microprocessor 20 of the apparatus body 12 receives the measurement instruction signal, and sends a prohibiting signal indicating the prohibition of the transverse feeding operation of the ten-sample rack 226 to the control unit 38 of the transporting apparatus Y. After transmitting the prohibiting information, the microprocessor 20 of the apparatus body 12 performs the operation of aspirating the sample from the test tube 32 (position 1) of the ten-sample rack 226 transversely fed to the aspirating position facing the sample aspirating part 10a. When the aspirating operation is terminated, the microprocessor 20 sends a permitting signal indicating permission of transverse feeding operation of the ten-sample rack 226 (or aspirate terminated signal indicating that aspirating operation is terminated) to the control unit 38 of the transporting apparatus Y. The microprocessor 40 of the transporting apparatus Y feeds the ten-sample rack 226 transversely so that the next test tube 32 (position 2) of the ten-sample rack 226 comes to the aspirating position facing the sample aspirating part 10a. Thereafter, the microprocessor 40 sends information on the measurement instruction to the measurement control unit 16. Such procedure is repeatedly performed for all the test tubes 32 accommodated in the ten-sample rack 226.
Various setting items are listed in the up and down direction in the item display window H2, and one of the items is a connection setting item (connection, sampler/transportation) H2a of the transporting apparatus 11. When the item H2a is selected, the relevant item name is displayed in the selected item display part H3. One of the set values displayed on the set value display part H5 can be input to the input field H4. In the present example, the set value of one of “0” to “4” can be input. Specific names etc. of the transporting apparatus 11 to be connected are displayed next to each set value “0” to “4” in the set value display part H5.
The relationship between the type (X, Y, Z, W) of the transporting apparatus 11 connected to the analyzer 10 and the set values “0” to “4” is as shown in FIG. 18. The set value “0” is the set value of “standard mode” selected when the transporting apparatus 11 is not connected to the analyzer 10. In this case, only manual measurement of supplying the sample to the analyzer 10 by hand can be performed.
The set value “1” is the set value of “transporting apparatus X mode” selected when the transporting apparatus 11 (transporting apparatus X shown in FIG. 8(a)) for the ten-sample rack is connected to the analyzer 10. The transporting apparatus X does not have a control unit, and is controlled by the measurement control unit 16 (FIG. 3) of the analyzer 10.
The set value “2” is the set value of “transporting apparatus Y mode” selected when the transporting apparatus 11 (Y) including the control unit 38 (FIG. 3) is connected to the analyzer 10. The set value “3” is the set value of “transporting apparatus Z mode” selected when the transporting apparatus 11 (Z) including the control unit 38 (FIG. 3) different from the transporting apparatus Y is connected to the analyzer 10.
The set value “4” is the set value of “transporting apparatus W mode” selected when the transporting apparatus 11 (transporting apparatus W shown in FIG. 8(b)) for the five-sample rack is connected to the analyzer 10. The transporting apparatus W does not have a control unit, and is controlled by the measurement control unit 16 (FIG. 3) of the analyzer 10. Therefore, in the present embodiment, the operation program to be executed by the system controller 13, the input part 29, and the like configure the input means for inputting the identification information of the transporting apparatus 11.
Returning to the flowchart shown in FIG. 13, the continuation of the procedure for setting the set values of the transporting apparatus will be described. In step S4, the system controller 13 determines whether or not the selection of the transporting apparatus is accepted, that is, whether or not the input of the set value “0” to “4” is made from the operation program of the system controller 13 as described above. If the set value is input, the system controller 13 transmits a signal corresponding to the relevant transporting apparatus to the measurement control unit 16 of the apparatus body 12 (step S5). The measurement control unit 16 determines whether or not the signal corresponding to the transporting apparatus is received (step S7), and if the relevant signal is received, stores the set value of the transporting apparatus corresponding to the signal in the memory 21 and terminates the process (step S8).
The measurement control unit 16 of the apparatus body 12 determines whether or not the start signal is received in step S43, and when the measurement start signal is received, reads out the transporting apparatus measurement program from the memory 21 in step S44, and reads out the transporting apparatus set value from the memory 21 (step S45). In step S46, the measurement control unit 16 determines what the transporting apparatus set value is (step S46). The measurement control unit 16 executes the transporting apparatus X program when the set value is “1”, (step S47a), executes the transporting apparatus Y program when the set value is “2” (step S47b), executes the transporting apparatus Z program when the set value is “3” (Step S47c), and executes the transporting apparatus W program when the set value is “4” (step S47d).
In step S65, the system controller 13 determines whether or not the operation state signal is received, and if the operation state signal is received, displays the display indicating “in measurement operation” on the display 28 (step S66). If the operation state signal is not received in step S65, the system controller 13 returns the process to step S62. The system controller 13 determines whether or not the measurement completed signal is received in step S67, and if the measurement completed signal is received, returns the process to step S62, and if the measurement completed signal is not received, returns the process to step S66.
The second embodiment of the present invention will now be described. As shown in FIG. 20, in the second embodiment, an identifying part 42 including the identification information for identifying the type is arranged in each transporting apparatus 11, and detection means 43 for detecting the identifying part 42 is arranged in the analyzer 10. The detection means 43 includes detection sensors 43A, 43B made of optical sensor, and the identifying part 42 is configured by a light shielding plate for light shielding the detection sensor 43.
FIG. 21 is an explanatory view showing a relationship between the detection sensors 43A, 43B and the light shielding plate 42. In the present embodiment, four patterns of when three types of transporting apparatus 11 are connected and when the transporting apparatus 11 is not connected are identifiable. Specifically, two detection sensors (first, second sensors) 43A, 43B are arranged in the analyzer 10, and the light shielding plate 42 as shown in FIGS. 21(a) to 21(c) is arranged in each transporting apparatus 11. In the second embodiment, three types of X, Y, and Z are identified of the four types X, Y, Z, W (see FIG. 3 and FIG. 18) of transporting apparatuses 11 described in the first embodiment.
Two light shielding parts 42a, 42b for light shielding the detection sensors 43A, 43B are arranged in the light shielding plate 42 of the transporting apparatus X of FIG. 21(a). One light shielding part 42a for shielding only the first detection sensor 43A is arranged in the light shielding plate 42 of the transporting apparatus Y of FIG. 21(b), and one light shielding part 42b for light shielding only the second detection sensor 42B is arranged in the light shielding plate 42 of the transporting apparatus Z of FIG. 21(c).
The relationship between the type (X, Y, Z) of the transporting apparatus 11 connected to the analyzer 10 and the state and output of the first and second detection sensors 43A, 43B is as shown in FIG. 22. According to FIG. 22, when the transporting apparatus X is connected to the analyzer 10, both the first and second detection sensors 43A, 43B are light shielded (state of FIG. 21(a)), and both output becomes Low level. When the transporting apparatus Y is connected, the first detection sensor 43A is light shielded and the output thereof becomes Low level, but the second detection sensor 43B is not light shielded and is in an light incident state, and thus the output thereof becomes High level (state of FIG. 32 (b)). When the transporting apparatus Z is connected, the second detection sensor 43B is light shielded and the output thereof becomes Low level, but the first detection sensor 43A is not light shielded and is in an light incident state, and thus the output thereof becomes High level (state of FIG. 32(c)). When the transporting apparatus is not connected, both the first and second detection sensors 43A, 43B are not light shielded and are in an light incident state, and thus both output becomes High level.
FIG. 24 is a flowchart showing a procedure of when the analyzer 10 connected with the transporting apparatus 11 automatically identifies the type of the transporting apparatus, and performs the transporting apparatus measurement mode. The flow chart of FIG. 24 differs from the flowchart of FIG. 19 in steps S145 and S146, and steps S45 and S46, where step S47d is not provided in the flowchart of FIG. 24, but other steps are the same between the flowchart of FIG. 24 and the flowchart of FIG. 19. As shown in FIG. 24, the measurement control unit 16 of the apparatus body 12 reads out the output signals of the detection sensors 43A, 43B in step S145, and determines the combination of the output signals of the detection sensors 43A, 43B (step S146). The measurement control unit 16 executes the transporting apparatus X program when the combination of the output signals of the detection sensors 43A, 43B is (Low, Low) (step S47a), executes the transporting apparatus Y program when the combination of the output signals of the detection sensors 43A, 43B is (Low, High) (step S47b), and executes the transporting apparatus Z program when the combination of the output signals of the detection sensors 43A, 43B is (High, Low) (step S47c). Other processes are similar to the processes in the flowchart of FIG. 13.
In the first embodiment, the set value specifying the transporting apparatus 11 is stored in the memory 21 of the measurement control unit 16, but the present invention is not limited thereto, and may be stored in the hard disc 27d of the system controller 13, so that the system controller 13 transmits the set value to the measurement control unit 16 in the initialization process when activating the analyzer 10 from the next time.
In the first embodiment, the operation when the transporting apparatus 11 is not connected to the analyzer 10 is not described, but when the set value “0” identifying the transporting apparatus 11 is input to the input part 29 of the system controller 13 by the user, the set value “0” is transmitted to the measurement control unit 16, the set value “0” is stored in the memory 21 by the control unit 16, and the stored set value “0” is read out, whereby the manual measurement program is executed.
