Description

Reagent library and automatic analyzer

Technical Field

The present utility model relates to a reagent library and an automatic analyzer.

Background

An automatic analyzer is an apparatus that optically measures a mixture of a sample sampled from a subject and a reagent for analyzing each test item, and generates analysis data for the biochemical test item, the immunological test item, the hemagglutination test item, and the like. The automatic analyzer stores a reagent for detection in a reagent reservoir, conveys a sample container for storing a standard sample or a sample to be tested by a conveyor, and measures a mixed solution of the reagent and the standard sample or a mixed solution of the reagent and the sample to be tested by a reaction unit. The opening of the reagent container is likely to be degraded by evaporation of the reagent if left open for a long period of time, and therefore the opening of the reagent container needs to be closed by a lid structure.

In the related art, there is a method of opening an opening of a reagent container by bringing a swing arm of a lid of the reagent container into contact with an opening/closing block in a reagent container. However, in this structure, the opening direction of the cover is a vertical direction, and a large space needs to be reserved between the opening of the reagent container and the reagent reservoir cover. In addition, in the working state, the reagent container continuously rotates around the center of the reagent container, and the reagent container needs to be opened and closed once through the opening and closing block, so that unnecessary friction is increased, and the generated abrasion powder can circulate in the reagent container and enter the reagent container to pollute the reagent.

(first embodiment)

Fig. 1 is a schematic diagram showing the structure of an automatic analyzer 1 according to the present utility model.

Next, an exemplary configuration of an automatic analyzer 1 according to the present utility model will be described with reference to fig. 1.

The automatic analyzer 1 is a device for generating analysis data by optically measuring a mixture of a sample sampled from a subject and a reagent for analyzing each test item, with respect to a biochemical test item, an immunological test item, a blood coagulation test item, or the like.

As shown in fig. 1, the automatic analyzer 1 includes a conveyor belt 2, a sample dispensing arm 21, a reagent reservoir 3, a reagent dispensing arm 81, a reaction section 4, a stirring arm 41, a measuring section 5, a washing section 6, and a control system 7.

The conveyor 2 is provided so as to extend in the X-axis direction (front-rear direction), and the conveyor 2 movably holds a sample rack in which sample containers are housed.

An annular rotating rail is provided in the reagent reservoir 3, and a reagent container containing a reagent is placed on the rotating rail. The reagent containers are arranged at equal intervals along the annular rotation track of the reagent reservoir 3. The reagent reservoir 3 is rotatably and movably held in an endless rotation track. The reagent container is cooled by the reagent pack 3.

An annular rotation rail is provided in the reaction section 4, and a reaction vessel containing a mixed solution of a sample and a reagent is placed on the rotation rail. The reaction vessels are arranged at equal intervals along the annular rotation orbit of the reaction part 4. The reaction part 4 rotatably holds an endless rotation rail.

The sample dispensing arm 21 is rotatably provided around its own axis parallel to the Y axis between the reaction part 4 and the conveyor belt 2. The sample dispensing arm 21 has a sample dispensing probe at one end. The sample dispensing probe rotates with rotation of the sample dispensing arm 21. The rotational path of the sample dispensing probe intersects with the rotational orbits of the sample container on the conveyor belt 2 and the reaction container in the reaction section 4, respectively, and the intersection point of the rotational path of the sample dispensing probe with the rotational orbits of the sample container on the conveyor belt 2 and the reaction container in the reaction section 4 becomes a sample suction position and a sample discharge position.

The sample dispensing arm 21 samples a sample, and the sample dispensing arm 21 transfers the sample between the sample container of the conveyor belt 2 and the reaction container of the reaction unit 4. The sample dispensing arm 21 is liftable in the longitudinal direction (Y-axis direction) to move the sample dispensing probe in the longitudinal direction between a sample suction position and a sample discharge position. The sample dispensing probe sucks a standard sample in a sample container located at a sample suction position, and dispenses the sample into a reaction container located at a sample discharge position in the reaction part 4. The sample dispensing probe sucks the sample to be measured in the sample container located at the sample suction position, and dispenses the sample to the reaction container stopped at the sample discharge position in the reaction section 4.

The reagent dispensing arm 81 is rotatably provided between the reagent reservoir 3 and the reaction part 4 about its own axis parallel to the Y axis. The reagent dispensing arm 81 has a reagent dispensing probe. The reagent dispensing probe rotates with the rotation of the reagent dispensing arm 81. The rotational path of the reagent dispensing probe intersects with the rotational path of the reagent container in the reagent reservoir 3 and the rotational path of the reaction container in the reaction unit 4, respectively, and the intersection point between the rotational path of the reagent dispensing probe and the rotational path of the reagent container in the reagent reservoir 3 and the rotational path of the reaction container in the reaction unit 4 becomes the reagent suction position and the reagent discharge position.

The reagent dispensing arm 81 transfers a reagent between the reagent container of the reagent reservoir 3 and the reaction container of the reaction unit 4. The reagent dispensing arm 81 is movable up and down in the longitudinal direction (Y-axis direction) to move the reagent dispensing probe in the longitudinal direction between the reagent suction position and the reagent discharge position. The reagent dispensing probe sucks the reagent in the reagent container located at the reagent sucking position, and dispenses the reagent into the reaction container located at the reagent discharging position in the reaction part 4.

After the standard sample, the sample to be tested, and the reagent are discharged from the sample dispensing probe by the stirring arm 41, the mixed solution of the standard sample and the reagent or the mixed solution of the sample to be tested and the reagent in the reaction vessel stopped at the stirring position in the reaction section 4 is stirred.

The measurement unit 5 optically measures the mixed solution in the reaction vessel in the reaction unit 4. The measuring unit 5 irradiates the mixed solution in each reaction vessel in the reaction unit 4 with light, and the measuring unit 5 detects the light transmitted through the mixed solution in the reaction vessel in the reaction unit 4, and generates standard data and test data expressed by, for example, absorbance or a change amount of absorbance based on the obtained detection signal.

The cleaning unit 6 cleans the reaction vessel stopped at the cleaning position in the reaction unit 4 in which the measurement by the measurement unit 5 is completed. The washing section 6 includes a waste liquid nozzle, a washing unit, and a drying nozzle. The washing section 6 sucks the mixed liquid as the waste liquid in the reaction vessel in the reaction section 4 through the waste liquid nozzle. The cleaning section 6 discharges a cleaning liquid to the reaction vessel from which the waste liquid has been sucked by the cleaning unit to clean the reaction vessel. The cleaning unit 6 supplies dry air to the cleaned reaction vessel through a drying nozzle, thereby drying the reaction vessel.

The control system 7 is electrically connected to and controls the above-described respective components.

Next, an exemplary structure of the reagent library 3a in the related art will be described with reference to fig. 2.

FIG. 2 is a schematic diagram showing the structure of a reagent reservoir 3a according to the prior art.

In the prior art, as shown in fig. 2, a reagent container 31a is accommodated in a reagent vessel 3a, and the reagent vessel 31a is rotatable around the center of the reagent vessel 3a. The cover 32a is detachably provided on the opening of the reagent vessel 31 a. The cover 32a is formed with a swing arm 33a extending toward the outer wall of the reagent reservoir 3a. An opening/closing block 34a located at the reagent dispensing position is fixedly provided on the outer wall of the reagent reservoir 3a, and the opening/closing block 34a is located on the rotation path of the reagent container 31 a. In the operating state, since the reagent container 31a continuously rotates in the reagent container 3a, the swing arm 33a of the reagent container 31a rotated to the opening/closing block 34a contacts the guide surface of the opening/closing block 34a, and the opening and closing of the cap 32a at the time of dispensing the reagent are guided by the guide surface of the opening/closing block 34 a.

However, in the prior art, the reagent vessel 31a is continuously rotated in the reagent vessel 3a, and the lid 32a is opened and closed once every time it passes the guide surface of the opening and closing block 34a, so that unnecessary friction is increased, and the generated abrasion powder may circulate in the reagent vessel 3a and enter the reagent vessel 31a to contaminate the reagent.

Next, a structure of the reagent container 3 according to the first embodiment, which prevents unnecessary repeated opening and closing of the opening and closing cover of the reagent container, will be described with reference to fig. 3.

Fig. 3 is a partial schematic view showing the inside of the reagent reservoir 3 according to the first embodiment.

As shown in fig. 3, in the present embodiment, the reagent pack 3 includes a reagent pack body 30, a reagent container 31, and an opening/closing mechanism 32.

The reagent container 31 is accommodated in the reagent pack body 30, and the reagent container 31 is used for accommodating a reagent. The plurality of reagent containers 31 are sequentially arranged around the center of the reagent pack body 30, and the reagent containers 31 are rotatable along the center of the reagent pack body 30.

The reagent vessel 31 includes a vessel main body 33 and an openable cover 34. The container body 33 has a bottle-like structure, and the reagent is contained in the container body 33. The open-close cover 34 is provided above the container main body 33, and the open-close cover 34 is slidable in a horizontal direction (i.e., a radial direction of the reagent pack main body 30), and the open-close cover 34 closes or opens the reagent in the container main body 33 by sliding in the horizontal direction. The openable cover 34 is provided with a magnetic body that can be attracted by the magnetic force of an electromagnet.

The opening and closing mechanism 32 is provided on the path of rotation of the reagent container 31, and the opening and closing mechanism 32 is located at the reagent dispensing position of the reagent reservoir 3. The opening and closing mechanism 32 slides the opening and closing cover 34 in the horizontal direction at a predetermined timing by turning on and off the electromagnet.

When the reagent container 31 is rotated to the reagent dispensing position and a reagent is required to be collected, the opening/closing mechanism 32 energizes the electromagnet to attract the magnetic body on the opening/closing cover 34, and slides the opening/closing cover 34 to open the reagent in the container main body 33. When the drug collection is completed, the opening and closing mechanism 32 releases the magnetic body on the opening and closing cover 34 by turning off the electromagnet, and slides the opening and closing cover 34 to close the reagent in the container main body 33. In the present embodiment, the opening/closing mechanism 32 opens the opening/closing lid 34 of the reagent container 31 only at the time of medicine collection, and does not operate the opening/closing lid 34 at other times than the time of medicine collection (for example, when the reagent container 31 is temporarily stopped at the medicine collection position or passes through the medicine collection position). Thus, unnecessary repeated friction between the opening and closing cover 34 of the reagent container 31 and the container main body 33 is avoided, deterioration of the reagent is prevented, and accuracy of the measurement result is ensured.

Next, a specific structure of the reagent container 31 of the reagent reservoir 3 according to the first embodiment will be described with reference to fig. 4, 5, and 6.

Fig. 4 is a partial schematic view showing the reagent container 31 in the reagent pack 3 according to the first embodiment.

Fig. 5 is another partial schematic view showing the reagent container 31 in the reagent pack 3 according to the first embodiment.

Fig. 6 is a schematic diagram showing the structure of the cap 341 of the reagent container 31 in the reagent pack 3 according to the first embodiment.

As shown in fig. 4 and 5, the container body 33 of the reagent container 31 includes a storage portion 331, a shoulder 332, and an opening 333.

The housing 331 is a bottle-shaped member having an upper opening, a shoulder 332 forming a horizontal top surface of the housing 331 is formed on the housing 331, an opening 333 is formed on the shoulder 332, and the opening 333 is used for sucking or dispensing the reagent in the housing 331.

The opening/closing cover 34 includes a cover seat 341, a cover plate 342, and a biasing portion 343.

The cap 341 is used to fix the opening/closing cap 34 to the shoulder 332 of the container body 33, and the cap 341 is substantially rectangular. The cover plate 342 is provided on the cover seat 341, and the cover plate 342 is a member extending substantially in the horizontal direction, and the cover plate 342 includes a portion extending in the horizontal direction (X-axis direction in fig. 4) and a portion extending in the longitudinal direction (Y-axis direction in fig. 4). The cover plate 342 is slidable on the cover seat 341 in a horizontal direction. The cover plate 342 is movable between a position (position in fig. 4) to close the opening 333 and a position (position in fig. 5) to expose the opening 333 by sliding in the horizontal direction on the cover seat 341. The urging portion 343 is provided between the cap base 341 and the cover plate 342, and one end of the urging portion 343 is connected to the cap base 341 and the other end is connected to a portion of the cover plate 342 extending in the longitudinal direction. The urging portion 343 urges the cover 342 so that the cover 342 can be returned to a position closing the opening 333 after sliding. Specifically, in the present embodiment, the tension spring is described as an example of the biasing portion 343, and the tension spring is always biased in the biasing direction (X-axis direction) so that a portion of the cover plate 342 extending in the longitudinal direction approaches the cover seat 341.

In the present embodiment, a part of the cover plate 342 extending in the horizontal direction and a part of the cover plate 342 extending in the longitudinal direction may be made of a magnetic metal material, and the whole of the cover plate 342 may be made of a magnetic material of the openable cover 34. In addition, only a part of the cover plate 342 extending in the longitudinal direction may be made of a magnetic metal material, and in this case, a part of the cover plate 342 may be a magnetic body of the openable cover 34. That is, the magnetic body on the opening/closing cover 34 constitutes at least a part of the cover plate 342. The cover plate 342 is entirely made of magnetic material, which reduces manufacturing difficulty and cost. The use of a part of the cover 342 as a magnetic material can reduce the overall weight of the cover 342, and can enhance the corrosion resistance of the cover 342.

As shown in fig. 6, a flange 3412 is formed at the edge of the top of the cap 341. The bottom of the cover seat 341 is formed with a hollowed recess 3411, the shape of the recess 3411 is matched with the shape of the shoulder 332, and the recess 3411 is used for sleeving the shoulder 332. The surface of the recess 3411 abutting against the shoulder 332 is provided with an adhesive, and is fixed to the shoulder 332 by the adhesive cap 341.

As shown in fig. 4 and 5, the edge of the portion of the cover plate 342 extending in the horizontal direction is formed with a sliding groove portion 3421, the shape of the sliding groove portion 3421 and the shape of the flange portion 3412 are matched with each other, the flange portion 3412 is embedded in the sliding groove portion 3421, and the sliding groove portion 3421 and the flange portion 3412 are matched with each other to enable the cover plate 342 to slide horizontally with respect to the cover seat 341.

Although the description has been made with the case where the flange 3412 is formed in the cover 341 and the slide groove 3421 is formed in the cover 342, the flange 3412 may be formed in the cover 342 by forming the slide groove 3421 in the cover 341, that is, one of the flange 3412 and the slide groove 3421 may be formed in the top of the cover 341 and the other of the flange 3412 and the slide groove 3421 may be formed in the cover 342.

As shown in fig. 4 and 5, the opening and closing mechanism 32 includes an electromagnet 321 and a fixing base 322.

In the present embodiment, since the tension spring is described as the biasing portion 343, the electromagnet 321 needs to be provided at one end of the opening/closing cover 34 in the +x direction along the biasing direction of the biasing portion 343 (i.e., the X-axis direction in fig. 4). The electromagnet 321 may be provided at one end of the openable cover 34 in the direction of biasing the biasing portion 343, and in this case, the biasing portion 343 may be replaced with a compression spring. The fixing base 322 is used for fixing the electromagnet 321, and the fixing base 322 may be disposed on the inner wall of the reagent pack body 30 of the reagent pack 3. In order to prevent the magnetism of the electromagnet 321 from interfering with other components, a holder 322 may be provided at the bottom of the cover of the reagent reservoir 3.

In the present embodiment, as shown in fig. 5, when the electromagnet 321 is energized, a magnetic force is generated to attract the magnetic body on the opening/closing cover 34, and the electromagnet 321 slides the cover plate 342 in the +x direction with respect to the cover seat 341 by attracting the magnetic body on the opening/closing cover 34, so that the opening 333 is opened.

As shown in fig. 4, when the electromagnet 321 is powered off, the magnetic body on the opening/closing cover 34 is released by the magnetic force, the cover 342 is pulled back in the direction approaching the cover seat 341 by the biasing portion 343, the cover 342 slides in the-X direction, and the opening 333 is closed.

As shown in fig. 4 and 5, in the present embodiment, a cover plate 342 having a rectangular flat plate shape is described as an example. However, the cover plate 342 may have any shape other than a rectangle, and it is sufficient that the opening 333 is closed after the electromagnet 321 is turned off and the cover plate 342 is reset, and the opening 333 is opened after the electromagnet 321 is turned on and the cover plate 342 is slid.

Next, a control process of the electromagnet 321 of the reagent reservoir 3 of the automatic analyzer 1 according to the first embodiment will be described with reference to fig. 7.

Fig. 7 is a control flow chart showing the control system 7 of the automatic analyzer 1 according to the first embodiment.

In the present embodiment, the control system 7 of the automatic analyzer 1 connects the opening/closing mechanism 32 to the reagent storage main body 30 and the reagent dispensing arm 81 of the automatic analyzer 1, and the control system sends an on/off electrical signal to the electromagnet 321 of the opening/closing mechanism 32 based on the operation information of the reagent dispensing arm 81 and/or the rotation state information of the reagent container 31, so that the opening/closing cover 34 of the reagent container 31 is opened only at the time of medicine collection.

The automatic analyzer 1 includes a sensor for detecting information on the operation of the reagent dispensing arm 81 or information on the rotational state of the reagent container 31, and transmitting the information to the control system 7. The information on the operation of the reagent dispensing arm 81 may be information on the time when the reagent dispensing arm 81 is lowered. The rotation state information of the reagent container 31 may be information when the rotation of the reagent container 31 is stopped and the reagent reservoir 3 is in a non-standby state. The rotation state information of the reagent container 31 may be information when the opening 333 of the reagent container 31 is shielded by the reagent dispensing probe of the reagent dispensing arm 81.

In fig. 7, n represents the number of sensors, and each sensor is used to detect the operation information of the reagent dispensing arm 81 or the rotational state information of the reagent container 31. And if the corresponding action is not detected, feeding back 0 to the upper position by each sensor, and if the corresponding action is detected, feeding back 1 to the upper position by each sensor. S1, S2, …, sn represent signal values fed back by the respective sensors.

As shown in fig. 7, when the automatic analyzer 1 starts to operate, first, in step P1, the system is initialized, the electromagnet 321 is not energized, the opening 333 is shielded by the cover plate 342 by the biasing unit 343, and at this time, the signal values s1=s2=sn=0 fed back by the respective sensors are entered into step P2. In step P2, the control system 7 sequentially reads the signal values S1, S2, & gt, sn fed back by the sensor, and proceeds to step P3. In step P3, the control system 7 determines whether or not the respective sensors detect the corresponding actions, and if at least one sensor detects the corresponding actions, s1+s2+.+sn+.noteq.0 indicates that the reagent container 31 has been rotated to the reagent dispensing position, and the reagent is required to be collected, and the process advances to step P4. In step P3, if no corresponding information is detected by all sensors, s1+s2+ &.+ sn=0, which means that no reagent needs to be collected, and the process returns to step P2. In step P4, the control system 7 controls the electromagnet 321 to be energized, and the opening/closing cover 34 is opened by the magnetic force of the electromagnet 321, so that the opening 333 is exposed, and the reagent container 31 positioned at the reagent dispensing position can be successfully collected, and the process proceeds to step P5. In step P5, the control system 7 determines whether or not to energize the electromagnet 321 for a predetermined time t, and returns to step P4 when the energization time does not reach the predetermined time t, which indicates that the medicine collection is not completed. In step P5, when the energization time reaches the predetermined time t, the process proceeds to step P6, which represents that the medicine collection is completed. In step P6, the control system 7 turns off the electromagnet 321, and the electromagnet 321 loses its magnetic force, so that the opening 333 is covered by the cover plate 342 that is reset by the urging portion 343, and the process proceeds to step P7. In step P7, the control system 7 determines whether the automatic analyzer 1 is stopped, and if the automatic analyzer 1 is not stopped, the process returns to step P1, and sets the signal values fed back by the respective sensors to 0, that is, s1=s2=. Sn=0, and the above-described flow continues. In step P7, when the automatic analyzer 1 stops operating, the entire flow ends.

According to the embodiment, the opening and closing cover of the reagent container is opened only when needed by controlling the on-off of the electromagnet, so that the opening and closing cover of the reagent container is prevented from being opened and closed repeatedly unnecessarily, the reagent is prevented from being degraded, and the accuracy of a measurement result is ensured.
