Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In all the drawings for describing the present embodiment, the same reference numerals are given to the same parts having the same functions in principle.
Fig. 1 is an overall view of the device exterior package in a state where the protective cover according to the embodiment of the present invention is closed. The apparatus cover of the automatic analyzer 101 includes a central protective cover 102, left and right upper covers (sample disk side) 103, and an upper cover (reagent disk side) 104, and is configured to cover a portion at risk of infection, such as a sample dispensing mechanism 206, with the protective cover 102 and to be protected by an interlock mechanism 208. The interlock mechanism 208 is configured to cut off the power supply when the protective cover 102 is opened. The central protective cover 102, the left and right upper covers (sample disk side) 103, and the upper cover (reagent disk side) 104 are configured to be opened and closed independently of each other.
Fig. 2 is a diagram showing an external appearance of the automatic analyzer according to the present embodiment in a state where the upper cover and the protective cover are opened. The upper cover (sample disk side) 103 and the upper cover (reagent disk side) 104 are covers that can be opened and closed by a general user even during an analysis operation, and are always opened and closed to facilitate access to the sample disk 207, the first reagent disk 201, and the second reagent disk 204. The first reagent dispensing mechanism 202 and the second reagent dispensing mechanism 203 are considered to be at low risk of infection, puncture, and the like, and therefore are disposed outside the protective cover 102 in the present embodiment, but may be disposed inside the protective cover 102. The protective cover 102 is a cover that can be opened and closed by a serviceman who performs maintenance work or a user who has been trained to perform certain operations, and protects the operation unit 403 of the sample dispensing mechanism 206 and the like that are considered to be at risk of infection, puncture, and the like. In addition, in order to prevent the user from accidentally opening the protective cover 102 and stopping analysis in the analysis operation, the protective cover 102 is locked by the protective cover locking mechanism 209 and cannot be opened during analysis.
Fig. 3(a) is an enlarged view of a portion a of fig. 2, and is a view showing the appearance of the interlock mechanism 208, the interlock release mechanism 303, and the maintenance key 301. In fig. 3(a), the shield case 102 is depicted by cutting out a cross section in order to easily understand the arrangement of the interlock mechanism 208. The interlock mechanism 208 is mainly composed of an interlock switch mechanism 302, an interlock release mechanism 303, and a maintenance key 301, and the maintenance key 301 is detachable. When the maintenance key 301 is inserted into the interlock release mechanism 208, the function of the interlock mechanism 208 that interrupts the power supply is released when the protective cover 102 is opened. Therefore, when the maintenance key 301 is inserted into the interlock release mechanism 208, power is supplied to the operating portion 403 regardless of opening and closing of the protective cover 102. In the present embodiment, for simplicity, the power supply is turned off only by inserting the maintenance key 301 into the interlock release mechanism 208, but an embodiment may be considered in which the power supply is not turned off only by inserting the maintenance key 301, and the maintenance key 301 is turned to the effective side to be turned on. As can be understood from this figure, in a state where the maintenance key 301 is inserted into the interlock release mechanism 303, the protective cover 102 and the maintenance key 301 physically interfere with each other, and the protective cover 102 cannot be completely closed, so that the user or the serviceman can recognize that there is a risk that the function of the interlock mechanism 208 is released.
Fig. 3(b) is a diagram schematically depicting fig. 3 (a). As shown in this figure, the interlock switch mechanism 302 is a switch mechanism that physically cuts off power.
Fig. 4 is a schematic diagram showing an electric circuit of the interlock mechanism 208 of the automatic analyzer according to the present embodiment. An operation unit 403 of a mechanism unit such as the sample dispensing mechanism 206 is schematically shown as a structure operated by supplying power from the power supply unit 401. A relay 402 is provided in a power line connecting the power supply unit 401 and the operation unit 403, and an interlock switch 404 and an interlock release switch 405 that can physically cut off the power supply are connected to the relay 402. The interlock switch 404 is a switch that constitutes a circuit in the following manner: when the interlock switch mechanism 302 is physically pressed, it is turned ON (ON), and power is supplied from the power supply portion 401 to the operation portion 403 via the relay 402. Further, the interlock release switch 405 is a switch that constitutes a circuit in the following manner: when the maintenance key 301 is inserted into the interlock release mechanism 303, it is turned ON (ON), and power is supplied from the power supply unit 401 to the operation unit 403 via the relay 402. The control unit 406 that controls the operation of the operation unit 403 controls the operation unit 403 based on the opening/closing information from the protective cover opening/closing detector 407 that detects the opening/closing of the protective cover 102 and the operation information from the interlock release switch 405.
Fig. 5(a) is a schematic view showing an example of the arrangement of the interlock mechanism 208 of the automatic analyzer according to the present embodiment, in which the maintenance key 301 is inserted into the interlock release switch 405. In the state where the protective cover 102 is opened, the interlock switch lever 501 cannot press the interlock switch mechanism 302, and therefore, power cannot be supplied to the operating portion 403, and the operating portion 403 cannot operate, so that safety of a general user can be ensured. However, maintenance requiring the operation of the operating unit 403, such as position adjustment and position confirmation of the sample probe of the sample dispensing mechanism 206, cannot be performed.
By inserting the maintenance key 301 into the interlock release mechanism 303 and switching the interlock release switch 405 to be enabled by the maintenance key 301, the maintenance person or the user trained to a certain degree can supply power to the operating portion 403 even in a state where the protective cover 102 is opened, and can perform maintenance requiring the operation of the operating portion 403. The opening and closing of the protection cover 102 can be confirmed by a protection cover opening and closing detection sensor 503. Since the opening/closing detection plate 502 is separated from the protective cover opening/closing detector 407 when the protective cover 102 is opened, the control unit 406 recognizes that the protective cover 102 is opened, and the control unit 406 controls the automatic analyzer 101 so that the automatic analyzer 101 does not enter the analyzing operation and instructs the automatic analyzer 101 to transmit an alarm or the like. Even when the control unit 406 recognizes that the open/close detection plate 502 is not inserted into the protective cover open/close detector 407 and the protective cover 102 is opened, the operation unit 403 is configured to be able to perform the maintenance operation when a maintenance person or a user with a certain training inserts the maintenance key 301 into the interlock release mechanism 303 and turns on the interlock release switch 405 with the maintenance key 301. The control unit 406 obtains opening/closing information of the protective cover opening/closing detector 407, and controls the operation of the operation unit 403 based on the information.
In the conventional technique, it is considered that the operation unit 403 is operated in an unexpected situation due to forgetting to pull out the maintenance key 301, and the like, and the safety of the general user cannot be ensured. For example, the insertion port of the maintenance key may be located at a position that does not interfere with the opening and closing operation of the protection cover, such as a front surface of the device. In the configuration of the present embodiment, in a state where the maintenance key 301 is inserted into the interlock releasing mechanism 303, the protection cover 102 cannot be closed because of physical interference with the maintenance key 301, and therefore forgetting to pull out can be visually prevented. Further, the protective cover opening/closing detector 407 detects that the protective cover 102 is not closed, and the control unit 406 issues an alarm. Thus, since the analysis operation as the main service of the general user cannot be performed, the safety of the general user is ensured by preventing the maintenance key 301 from being forgotten to be removed and disabling the operation unit 403.
Although the interlock releasing mechanism 303 is operated by the maintenance key 301 in the present embodiment, any configuration may be applied as long as it physically interferes with the protective cover 102 in a state where the interlock releasing mechanism 303 is operated. For example, an inverted switch, a screw switch, or the like may be applied as the operating member.
Fig. 5(b) is a schematic view showing an example of the arrangement of the interlock mechanism 208 and the interlock release mechanism 303 of the automatic analyzer according to the present embodiment, in which the maintenance key 301 is not inserted into the interlock release switch 405. When the maintenance key 301 is not inserted, the protective cover 102 can be closed, the interlock switch 501 presses the interlock switch mechanism 301, the interlock switch 404 is turned ON (ON), and power is supplied to the operation portion 403. Further, the control unit 406 recognizes that the opening/closing detection plate 502 is inserted into the protective cover opening/closing detector 407 and the protective cover 102 is closed, and the operation unit 403 can perform a normal operation.
Table 1 shows operation control of the operation unit 403 based on the relationship between the interlock release mechanism and the protection cover opening/closing detector. The control of the operating unit 403 is controlled by the control unit 406. When the maintenance key 301 is inserted into the interlock release mechanism 303, the interlock release mechanism 303 is enabled (the interlock mechanism 208 is disabled), and the open state of the protective cover opening/closing detector 407 is detected, maintenance work that needs to be performed while the protective cover 102 is open can be performed by a serviceman or a user with training. At this time, the automatic analyzer 101 is controlled to display an alarm on its display screen, and to disable the analysis operation. When the maintenance key is not inserted into the interlock release mechanism 303, the interlock release mechanism 303 is disabled (the interlock mechanism 208 is enabled), and the protection cover opening/closing detector 407 detects the closed state, the ordinary user can perform the analysis operation. In this case, the display screen of the automatic analyzer 101 may display that analysis is possible.
TABLE 1
Further, when the maintenance key 301 is inserted into the interlock release mechanism 303, the protection cover 102 interferes with the maintenance key 301, and therefore the protection cover open/close detector 407 does not detect the closed state.
