Description

[Technical Field]

[0001] The present invention relates to an automatic analyzer, and more particularly to an automatic analyzer having a static elimination function for user-accessible locations. [Background technology]

[0002] Automated analyzers mix biological samples such as plasma, serum, and urine with various reagents for analysis. The analysis results obtained by automated analyzers provide a wealth of information for diagnosing medical conditions. In recent years, there has been a demand for reducing the effects of electrostatic discharge on automated analyzers as one of the measures to further improve electromagnetic compatibility.

[0003] Here, there are Patent Documents 1 and 2 that relate to countermeasures against electrostatic discharge in a card connector device.

[0004] Patent document 1 describes a card connector device characterized in that it is provided with a metal cover that covers the card insertion section, the cover is connected to a ground pattern on a circuit board, and the opening and closing door is connected to the ground pattern of the circuit board via the cover.

[0005] Patent Document 2 describes a card connector comprising: "a housing fixed on a circuit board, forming a space in which an xD picture card (referred to as card) is stored with its terminal side facing downward, and having an opening for introducing the card into the space; and circuit terminals made of a conductive material which are held by the housing near the opening, one end of which is conductively connected to a circuit on the circuit board and the other end of which extends from the connection point with the circuit into the space, and which come into sliding contact with the terminal surface of the card when the card is introduced into the housing; a protective plate made of a sheet metal structure having an L-shaped or U-shaped cross section which covers the exposed portion of the circuit terminal near the opening and is connected to the ground potential on the circuit board, is provided on the circuit board; the L-shaped or U-shaped shape of the protective plate is shaped to guide the tip of the card from the opening into the space by an amount corresponding to the height of the circuit terminal from the circuit board when the card is inserted; and this protective plate prevents electrostatic discharge from the circuit." [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-203718 [Patent Document 2] Japanese Patent Application Laid-Open No. 2006-196355 Summary of the Invention [Problem to be solved by the invention]

[0007] Patent Documents 1 and 2 have in common a mechanism in which, when a card is inserted into a card connector, it comes into contact with metal connected to the ground pattern on the circuit board, thereby neutralizing the card and the user and protecting the card and the signal sections on the circuit board from electrostatic discharge.

[0008] However, if static electricity above a certain level is discharged to the ground pattern on a circuit board, the ground potential on the circuit will fluctuate, which may cause abnormal circuit operation and, in the worst case, may lead to the destruction of circuit elements. It is difficult to completely prevent abnormal circuit operation and the destruction of circuit elements caused by fluctuations in the circuit ground pattern with circuit-related measures, and the greater the static electricity discharged, the more difficult it becomes to take such measures.

[0009] In the case of an automated analyzer, one example of a user-accessible location that may be subject to malfunction due to electrostatic discharge is the USB port of the computer in the control unit. While the USB port is protected against static electricity by a metal shell or the like, as in Patent Documents 1 and 2, it is connected to a ground pattern on the computer's internal circuit board. If static electricity exceeding a certain level is discharged, the computer may malfunction, potentially resulting in malfunctions in the device's operation and analysis data. In an automated analyzer, abnormalities in analysis data, in particular, can lead to misdiagnosis and must be avoided without fail.

[0010] In order to avoid the above-mentioned abnormalities in an automatic analyzer, it is necessary to prevent electrostatic discharge to user-access points in the first place.

[0011] Therefore, an object of the present invention is to prevent electrostatic discharge to user-access points in an automatic analyzer. [Means for solving the problem]

[0012] As one aspect of solving the above problem, An automatic analyzer comprising an analysis unit that measures a liquid in which a sample and a reagent have reacted, and a control unit having a controller that controls the analysis unit, wherein the controller has a USB port that is accessed by a user, the USB port has a depth that is at least large enough to accommodate a USB memory, and an opening area that is at least large enough for a person's hand to enter, and is covered with a housing member that protrudes from a surface on which the USB port is provided, and a grounded static eliminator is attached to the opening or inside of the housing member. The present invention provides an automatic analyzer characterized by the above features. [Effects of the Invention]

[0013] According to the present invention, a structure is adopted in which static electricity is always removed via a static elimination member grounded outside the user access point immediately before or when the user accesses the user access point, thereby reliably preventing static electricity discharge to the user access point. Furthermore, since the present invention is an anti-static measure performed outside the user access point, it is possible to prevent static electricity from affecting the user access point and the automatic analyzer, regardless of whether or not anti-static measures are taken at the user access point itself.

[0015] Various embodiments of the present invention will be described below with reference to the drawings. First, the basic configuration of the device to which each embodiment is applied will be described.

[0016] The overall basic configuration of an automatic analyzer according to this embodiment will be outlined below with reference to Figures 1 and 2. The basic configuration described here is an example of the basic configuration of an automatic analyzer. 1, the automatic analyzer 100 is an apparatus for measuring a liquid in which a sample and a reagent have reacted, and is mainly equipped with a sample transport mechanism 104, a reaction disk 111, a reagent disk 109, a sample dispensing mechanism 101, a reagent dispensing mechanism 106, a stirring mechanism 113, a measurement unit (not shown), a cleaning mechanism 105, and a controller 102. Note that the sample referred to here means the blood or urine of a patient.

[0017] The analysis process of a sample by the automatic analyzer 100 is generally carried out in the following order.

[0018] First, the rack 103 is placed in a loading section or the like, and is carried by the sample transport mechanism 104 to the sample collection position of the automatic analyzer 100 .

[0019] When the rack 103 arrives at the sample dispensing position, the sample is dispensed into the reaction vessel 112 on the reaction disk 111 by the sample dispensing mechanism 101. The sample dispensing mechanism 101 dispenses the sample as many times as necessary according to the analysis items requested for the sample.

[0020] Furthermore, the reagent to be used for analysis is dispensed from the reagent bottle 108 on the reagent disk 109 by the reagent dispensing mechanism 106 into the reaction vessel 112 from which the sample was previously dispensed. Next, the stirring mechanism 113 stirs the reaction liquid prepared by mixing the sample and reagent in the reaction vessel 112.

[0021] Thereafter, light emitted from light source 107 is transmitted through reaction vessel 112 containing the stirred reaction liquid, and the luminous intensity of the transmitted light is measured by spectrophotometer 110. The luminous intensity measured by spectrophotometer 110 is sent to controller 102. Then, controller 102 performs a calculation to determine the concentration of a predetermined component in a liquid sample such as blood or urine, and the result is displayed on a display device or stored in a memory unit.

[0022] Figure 2 shows an example of the mounting location of the controller 102. In this example, the automatic analyzer is divided into a control unit 203 and an analysis unit 202, with the controller 102 mounted in a controller (computer) storage area 204 of the control unit 203, and the other components shown in Figure 1 mounted in the analysis unit 203. The controller 102 here is a computer equipped with a CPU, memory, etc., which controls the various operations of the above-mentioned components and performs arithmetic processing to determine the concentration of a predetermined component in a sample from the detection results of the spectrophotometer 110. The control of the operation of each device by the controller 102 is executed based on various programs recorded in a storage unit (not shown).

[0023] The control processes for the operations executed by the controller 102 may be integrated into one program, or may be divided into multiple programs, or may be a combination of these. Also, some or all of the programs may be realized by dedicated hardware, or may be modularized.

[0024] The computer is also equipped with a USB port and an optical drive, which can be used to update the program, output analysis results, and so on.

[0025] Hereinafter, specific examples of the present invention, in which an opening in a housing member is provided with a static eliminator that is grounded to the outside of a user access point, will be described with reference to the drawings. [Example]

[0026] In the first embodiment, a static elimination brush is used as the static elimination member, and the first embodiment will be described below with reference to FIGS.

[0027] Figure 3 is a schematic diagram 300 showing the area around a user access point (a computer and its USB port) mounted on an automatic analyzer. The user access point in Figure 3 is located in front of a USB port 302 of a computer 301, and includes a housing member 303 having a depth at least large enough to accommodate a USB memory and an opening area large enough for a person to insert their hand. An anti-static brush, which is an anti-static member 307 grounded outside the user access point, is disposed in an opening 304 of the housing member 303.

[0028] As an example of the charge removing member 307, a charge removing brush 407 as shown in FIG. 4A may be attached to the opening 404 of the housing member.

[0029] However, the area where no static elimination brush 407 is present when viewed from the front of housing member opening 404 must be sufficiently small compared to the area where a human hand can fit in. This restriction is intended to create a structure in which the user cannot access USB port 402, which is a user access point, unless the user touches static elimination brush 407, which is grounded outside the user access point.

[0030] In addition, the length of the charge removal brush 407 must be shorter than the depth of the housing member, in order to prevent the charge removal brush from coming into contact with the signal line inside the USB port 402 and causing a short circuit.

[0031] With the above structure, as shown in FIG. 4B, the user cannot access the USB port 402, which is a user access point, without necessarily touching the static elimination brush 407 that is grounded outside the user access point, and static electricity is reliably eliminated when the user is about to access or is accessing the user access point because the user is touching the static elimination brush that is grounded outside the user access point.

[0032] Considering a specific situation, as shown in steps (hereinafter abbreviated as S) 501 to S510 in FIG. 5, in both cases where a user inserts USB memory 408 into USB port 402, which is a user-accessed location, and where the user removes USB memory 408 from USB port 402, the user needs to insert / remove USB memory 408 while touching conductive anti-static brush 407 that is grounded outside the user-accessed location. Therefore, just before / when accessing USB port 402, which is a user-accessed location, the USB memory 408 is in a neutralized state, and no static electricity is discharged to USB port 402, which is a user-accessed location.

[0033] Therefore, by applying this embodiment, it is possible to reliably prevent electrostatic discharge to user access points. Furthermore, since this embodiment is an electrostatic countermeasure implemented outside the user access points, it is possible to reliably prevent damage and malfunction of the user access points and automatic analyzers caused by electrostatic discharge to the user access points, regardless of whether or not electrostatic countermeasures are implemented at the user access points themselves. [Example]

[0034] Example 2 is an example in which a metal chain is used as the static eliminator. That is, a structure in which a metal chain 607 as shown in Fig. 6A is arranged as the static eliminator attached to the housing member and grounded outside the user access point can be considered.

[0035] 6B, the structure of this embodiment makes it impossible for a user to access the USB port 602, which is the user access point, unless the user touches and lifts up the metal chain 607 that is grounded outside the user access point. Therefore, the user is reliably kept in a state of being neutralized immediately before or while accessing the user access point, and the same effect as in Example 1 can be obtained.

[0036] However, the area where metal chain 607 is not present when viewed from the front of housing member opening 604 must be sufficiently small compared to the area where a human hand can enter. This restriction is in order to maintain the structure that prevents a user from accessing USB port 602, which is the user access point, unless the user touches metal chain 607 that is grounded outside the user access point.

[0037] In addition, the range of movement of metal chain 607 in the depth direction of the housing member must be made smaller than the depth of the housing member, or the diameter of metal chain 607 must be made sufficiently larger than USB port 602. This restriction is to prevent the metal chain from coming into contact with the signal line inside USB port 602 and causing a short circuit. [Example]

[0038] Example 3 is an example in which an automatically closing door is used as the static eliminator. That is, as the static eliminator attached to the housing member and grounded outside the user access point, a structure in which an automatically closing door 707 grounded outside the user access point and having a mechanism for closing can be arranged as shown in Figures 7A and 7B.

[0039] With the above structure, as shown in S801 to S812 in FIG. 8, in both situations when a user inserts a USB memory into USB port 702, which is a user access point, and when the user removes the USB memory from USB port 702, the user must touch and open conductive door 707, which is grounded outside the user access point, before inserting / removing the USB memory. Therefore, just before or when the user accesses USB port 702, which is a user access point, the port is in a neutralized state, and no static electricity is discharged to USB port 702, which is a user access point.

[0040] Therefore, the user is surely kept in a state of being neutralized immediately before or while accessing the user access portion, and the same effects as those in the first and second embodiments can be obtained. [Example]

[0041] Example 4 is an example in which an automatically closing shutter mechanism is used as the static eliminator. That is, in Example 3, an automatically closing door 707 made of a conductor and grounded outside the user access point was attached to the opening 702 of the housing member 701 as the static eliminator, but in this example, as shown in Figures 9A and 9B, an automatically closing shutter mechanism 907 made of a conductor and using gravity, a spring, or the like is attached as the static eliminator. The structure of this example does not require space for the door to open and close, and therefore has the advantage of requiring less space on the front side of the housing member compared to Example 3.

[0042] By adopting the above structure, as in the third embodiment, the user cannot access the USB port 902, which is the user access point, unless the user touches and opens the shutter 907, which is made of a conductor that is grounded outside the user access point, with their hand, and immediately before or when the user accesses the user access point, the user comes into contact with the conductor that is grounded outside the user access point, thereby ensuring that static electricity is removed. Therefore, this embodiment can obtain the same effects as those of the first to third embodiments. [Example]

[0043] The fifth embodiment uses an automatically closing shutter mechanism as the static eliminator, which has a gap for passing a wired cable or the like.

[0044] In the first and second embodiments, an electrically conductive automatically closing door 707 / shutter 907 that is grounded to the outside of the user access point is attached to the opening of the storage member as a static elimination member, but the structure does not necessarily have to be a structure that seals the storage member.

[0045] 10A and 10B, a gap 1008 may be provided for passing a USB cable for a wired keyboard or the like. However, this gap 1008 must be sufficiently smaller than the area that a human hand can fit through. This restriction is intended to maintain the structure that prevents access to the USB port 1002, which is the user access point, unless the user uses their hand to touch and open the opening / closing door 707 / shutter 907, which is made of a conductor and is grounded outside the user access point.

[0046] The effect of adopting the above structure is the same as that of the third and fourth embodiments. [Example]

[0047] Example 6 is an example in which a static elimination brush is used inside the housing member as the static elimination member. That is, while Examples 1 and 2 have a structure in which static elimination brush 407 / metal chain 607 grounded outside the user access point is attached to housing member opening 404 / 604 as the static elimination member, Example 6 is an example in which static elimination brush 1107 / metal chain 1107 is attached inside the housing member as shown in Figures 11A and 11B.

[0048] However, in this embodiment, the restrictions described in the first and second embodiments must also be met.

[0049] The effect obtained when this embodiment is applied is the same as that of the first to fifth embodiments. [Example]

[0050] Example 7 is an example of a configuration in which the user access point is brought outside. That is, in Examples 1 to 6, the housing member is arranged in front of the USB port 302 which is the user access point, but it is also possible to provide the user access point at another location using a USB extension cable 1208 or the like as shown in Fig. 12 and adopt the same structures of the housing member and the static eliminator as in Examples 1 to 6.

[0051] The structure of this embodiment is effective in situations where it is difficult to adopt the structures of embodiments 1 to 6 around a user access point, or when it is desired to place the USB port 1202 of a computer in a location that is more user-friendly for the user, for example.

[0052] The effect obtained when this embodiment is applied is the same as that of the first to sixth embodiments. [Example]

[0053] In the first to seventh embodiments, the static eliminator is described as being grounded outside the user-accessible area, but there are several possible methods for grounding it.

[0054] For example, as shown in Fig. 13, a method of connecting the static eliminator 1307 to the metal casing 1305 of the automatic analyzer via a ground wire 1306 is conceivable, or a structure is adopted in which the static eliminator 1407, including the housing member 1403, is directly incorporated into the metal casing 1405 of the automatic analyzer, as shown in Fig. 14. However, in this case, the metal casing of the automatic analyzer is assumed to be protectively grounded.

[0055] The grounding method shown in this embodiment is merely an example, and any method may be used as long as the charge eliminating members 1307 / 1407 are not directly grounded to the user access point but are grounded outside the user access point. [Example]

[0056] In Examples 1 to 8, a structure is described in which an anti-static member is attached to the opening of the storage member, but the storage member may be made of a conductive material that is grounded outside the user access point, and the storage member itself may be provided with a mechanism for opening and closing.

[0057] As shown in Figures 15A and 15B, a housing member 1503 having a volume large enough to accommodate at least a USB memory, grounded outside the user access point, and equipped with a conductive mechanism that automatically returns to its original position is placed in front of a USB port 1502 of a computer 1501, which is the user access point.

[0058] In the case of this structure, as in Examples 4 and 5, as shown in S1601 to S1612 of FIG. 16, in both situations when a user inserts a USB memory into USB port 1502, which is a user access point, and when the user removes the USB memory from USB port 1502, the user must touch and open conductive housing member 1503, which is grounded outside the user access point, before inserting / removing the USB memory. Therefore, just before / when accessing USB port 1502, which is a user access point, the USB port is in a neutralized state, and no static electricity is discharged to USB port 1502, which is a user access point.

[0059] Therefore, the effect obtained when this embodiment is applied is the same as that of the first to eighth embodiments. [Example]

[0060] In Examples 1 to 9, a static eliminator that is grounded outside a user access point is described, but the material is assumed to be a highly conductive substance such as metal. Also, it is not necessary for all conductive members to be made of a highly conductive material; for example, there is no problem if the parts that people touch are highly conductive, such as metal plating or conductive coating, and they are simply grounded outside a user access point. [Example]

[0061] In this embodiment, the effects of the anti-static measures of the first to ninth embodiments will be described in the case where a user wears insulating gloves such as medical gloves.

[0062] As shown in Figure 17, when a user wearing insulating gloves touches a grounded conductor, only the surface of the glove worn on the hand that touched the conductor is neutralized, while the user's body and the surface of the glove on the other hand remain charged. In this state, if the user's body surface or the hand that did not touch the conductor touches the conductor, a static discharge occurs.

[0063] In Examples 1 to 8 of the present invention, the device is designed so that the user touches the static eliminator before accessing the interior of the housing member, and therefore the hand wearing the insulating glove accessing the user access point will access the USB port, which is the user access point, in a neutralized state. Furthermore, medical gloves are typically worn tightly covering the wrist, and the housing member is positioned in front of the user access point, so the user's body surface will not come into contact with the USB port, which is the user access point. Therefore, in Examples 1 to 8 of the present invention, even if the user is wearing insulating gloves, no static electricity will be discharged to the user access point.

[0064] However, in Examples 3 to 5, it is possible that the hand that touches the static eliminator and the hand that accesses the user access point are different. Therefore, if it is assumed that the user will wear insulating gloves, it is desirable to adopt Examples 1 to 2 or Example 6. [Example]

[0065] In the first to ninth embodiments, a USB port of a computer is described in detail as an example of a user access point, but the scope of application of the present invention is not limited to a USB port of a computer, and can be applied to, for example, an optical drive unit, a power button unit, various connector units for video signals, etc. Furthermore, the present invention is not limited to computers, and can be applied to, for example, various buttons, connector units, etc. that a user may touch.

[0066] The effect in this case is the same as in Examples 1 to 9, as static electricity is removed immediately before or while the user is accessing the user access point, so damage or malfunction of the user access point or device due to static electricity can be prevented regardless of whether or not anti-static measures are taken at the user access point itself.

[0067] The present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations. Furthermore, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add another embodiment to the configuration of one embodiment. Furthermore, it is also possible to add, delete, or replace part of the configuration of each embodiment with other configurations. [Explanation of symbols]
