Description

  The present invention relates to an ultrasonic diagnostic apparatus provided with a drawer-type movable operation board (for example, a keyboard), and more particularly to an ultrasonic diagnostic apparatus that is intended for use in a relatively dark place.

  An ultrasonic diagnostic apparatus that transmits ultrasonic waves to a subject via an ultrasonic probe and receives an echo signal from the subject, obtains an ultrasonic image based on the echo signal, and inspects the subject. Is widely used in the medical field. The ultrasonic diagnostic apparatus can be equipped with a plurality of types of ultrasonic probes so that appropriate ultrasonic probes can be exchanged and used according to the diagnostic purpose such as the examination site and the condition of the subject. There are many things. For example, Patent Document 1 discloses an example of an ultrasonic diagnostic apparatus to which a plurality of types of ultrasonic probes can be attached.

  Each ultrasonic probe is detachable from the main body of the ultrasonic diagnostic apparatus via a connector (hereinafter, the connector of the ultrasonic probe is referred to as a “probe connector”). An arbitrary ultrasonic probe can be selectively used by connecting the ultrasonic diagnostic apparatus main body with a probe connector and switching the switch on the ultrasonic diagnostic apparatus main body side. The ultrasonic probe connected to these probe connectors is called an active ultrasonic probe.

  On the other hand, when using more than the number of probe connectors in the inspection, there are several ultrasonic probes that are not connected to the probe connector but can be used immediately if they are connected to the probe connector. Such an ultrasonic probe is sometimes referred to as a standby ultrasonic probe. Those that are relatively infrequently used become standby ultrasonic probes that are connected to and stored in a connector called a dummy connector that is not supplied with power, and are used in exchange for an active ultrasonic probe as necessary. .

  In many cases, a device that may be used for diagnosis, such as a probe connector, an ECG monitor connector, or a USB (Universal Serial Bus) connector, or a connector of the device is disposed on the front surface of the ultrasonic diagnostic apparatus main body. This is because, when a connector is arranged on the side, when an ultrasonic diagnosis is performed by placing the apparatus main body beside the bed, the device or the cable of the device connected to the connector interferes with the patient on the bed or the bed. Because.

  In addition, when a device such as a probe connector or a connector of a device that may be used for diagnosis is arranged on the front surface of the ultrasonic diagnostic apparatus, the device or the connector of the device is fixedly placed on the upper front of the ultrasonic diagnostic device. Often located below the panel. This is to prevent the device or the cable of the device connected to the connector from interfering with the operation of the fixed operation panel by the operator.

  On the other hand, a conventional ultrasonic diagnostic apparatus is provided with a movable operation board (for example, a keyboard) for inputting patient information, in addition to a fixed operation panel for performing operations related to acquisition of ultrasonic images. There is a case. In particular, an ultrasonic diagnostic apparatus in which the entire apparatus is miniaturized may employ a pull-out type movable operation board for the purpose of shortening the depth of the apparatus main body.

  Such a movable operation board may be provided with an illumination unit such as an LED (Light Emitting Diode) that illuminates the movable operation board, or a mechanism in which a key on the movable operation board emits light. This is because the inspection by the ultrasonic diagnostic apparatus is often performed in a relatively dark place.

JP 2006-026046 A

  Device or equipment connector used for diagnosis, such as a probe connector located on the front of the device body located below the fixed operation panel, has a fixed operation panel placed on top to cover the connector of the equipment or device. Because the light is blocked, it is darker than the surroundings of the ultrasonic diagnostic apparatus. Nevertheless, since there is no mechanism for illuminating the device or the connector of the device, it is very difficult to distinguish the probe type and probe connector when replacing the probe in a relatively dark place. .

  Although it is possible to newly provide an illuminating unit for illuminating the probe connector with respect to the above problem, in this case, another problem arises that wiring is complicated by newly providing the illuminating unit.

  The present invention solves the above-described problem, and illuminates the movable operation board and the front of the apparatus main body located below the fixed operation panel with a single illumination unit, so that the wiring is relatively dark without complicating the wiring. However, it is intended to make it possible to visually recognize devices used for diagnosis such as probe connectors or connectors of devices.

  In order to achieve the above object, the invention according to claim 1 is a device main body in which a probe connector for connecting an ultrasonic probe is arranged on the front surface, and the probe connector from above the device main body on the front side of the device main body. A fixed operation panel arranged so as to cover the movable operation board, a movable operation board positioned between the fixed operation panel and the probe connector, and a storage position in which the movable operation board is stored below the fixed operation panel A guide support member that guides and supports the movable operation board so that the movable operation board can be moved from the bottom of the fixed operation panel to the front side, and when the movable operation board moves to the use position. When the movable operation board is moved to the stowed position and is directed to illuminate the upper surface of the movable operation board moved to the front use position Is an ultrasonic diagnostic apparatus characterized by comprising a said illumination unit that is directed to illuminate the probe connector positioned below the fixed operation panel.

  According to the present invention, the illumination of the device or the connector of the device used during diagnosis such as the probe connector positioned below the fixed operation panel and the illumination unit that illuminates the movable operation board are combined. As a result, the lighting unit and the wiring to the lighting unit are consolidated in one place, and it is possible to illuminate both the upper surface of the movable operation board and the device used during diagnosis including the probe connector or the connector of the device. Therefore, the device including the probe connector or the connector of the device can be visually recognized even in a relatively dark place.

  Furthermore, when illumination is performed by the illumination unit, the operation target corresponding to the form is illuminated according to the position of the movable operation board, so that the operator can be guided to the position of the operation target.

In addition, in FIG. 4, the member attached with the number enclosed by () is located on the back side of the member attached with the number without ().

  First, an outline of the configuration of the operation unit 2 will be described. Below the fixed operation panel 201, a movable operation board 240 is supported from both sides by a guide support member 230 and a front link member 212 (see FIG. 4). At this time, the movable operation board 240 is guided so as to be movable along the guide support member 230. The fixed operation panel 201 and the front link member 212, and the front link member 212 and the guide support member 230 are rotatably attached to each other, and the fixed operation panel 201, the front link member 212, and the guide support member 230 constitute a link mechanism. is doing. The illumination unit 220 is fixed to the front link member 212, and the illumination unit 220 is directed in different directions as the front link member 212 rotates. When the movable operation board 240 is pushed below the fixed operation panel 201, the front link member 212 rotates to the front of the guide support member 230 around the rotation shaft 214, and the illumination unit 220 is positioned below the fixed operation panel 201. The probe connector 3 is directed in the direction of illuminating (see FIG. 3A). When the movable operation board 240 is pulled out from below the fixed operation panel 201, the front link member 212 is rotated behind the guide support member 230 around the rotation shaft 214, and the movable operation board 240 from which the illumination unit 220 is pulled out is generated. The top surface is directed to illuminate (see FIG. 3C). Hereinafter, the details of each part constituting the operation unit 2 will be specifically described.

  As shown in FIG. 4, the guide support member 230 has a substantially U-shaped cross-sectional shape and is fitted to both side surfaces of the movable operation board 240 so that the movable operation board 240 is placed below the fixed operation panel 201. To support.

  The movable operation board 240 is positioned below the fixed operation panel 201 by the guide support member 230 (see FIG. 3B, hereinafter this position is referred to as “storage position”), and the movable operation board. 240 is guided so as to be movable between a position where the 240 is pulled out from the bottom of the fixed operation panel 201 (see FIG. 3C, hereinafter this position is referred to as “use position”). Specific operations of the movable operation board 240 will be described later.

  The front link member 212 is attached such that at least one end thereof is rotatable relative to each other about a support member 211 and a rotation shaft 213 fixed to the front side surface of the fixed operation panel 201. The other end of the front link member 212 is attached to the front side surface of the guide support member 230 so as to be rotatable relative to the guide support member 230 about the rotation shaft 214. Support downward. Thereby, the fixed operation panel 201, the front link member 212, and the guide support member 230 form a link mechanism.

  When a force that pushes the guide support member 230 rearward is applied, the link support mechanism causes the guide support member 230 to swing backward and rearward from the fixed operation panel 201 (see FIG. 3A). The position where the guide support member 230 is swung back and forth is referred to as a back and forth swing position.

  At this time, the front link member 212 rotates around the rotation shaft 214 to the front of the guide support member 230, and one end of the front link member 212 on the rotation shaft 214 side rotates backward about the rotation shaft 213.

  Further, when a force for pulling the guide support member 230 forward is applied, the link support mechanism causes the guide support member 230 to move forward and downward toward the lower front side of the fixed operation panel 201 (see FIG. 3B). The position where the guide support member 230 has been swung forward is referred to as a forward swing position.

  At this time, the front link member 212 rotates rearward about the rotation shaft 214 and rises, and one end of the front link member 212 on the rotation shaft 214 side rotates forward about the rotation shaft 213.

  As shown in FIG. 4, the illumination unit 220 is fixed to the outer peripheral side surface of the shaft member 219 installed and fixed to the front link member 212, and is directed in different directions in conjunction with the rotation of the front link member 212.

  When the front link member 212 rotates backward about the rotation shaft 214, the shaft member 219 rotates in conjunction with the front link member 212, and the illumination unit 220 moves to the front use position of the movable operation board 240. Directed in the direction of lighting.

  Further, when the front link member 212 rotates in front of the guide support member 230 around the rotation shaft 214, the shaft member 219 rotates in conjunction with the front link member 212, and the illumination unit 220 is positioned below the fixed operation panel 201. The probe connector 3 positioned is directed to illuminate.

  At this time, since the illumination unit 220 moves forward from the front end portion of the movable operation board 240 moved to the storage position, the probe connector 3 or the like that is located below the fixed operation panel 201 is used during diagnosis. The connector can be illuminated.

  The rear link member 216 is attached such that at least one end thereof is fixed to the rear side surface of the fixed operation panel 201 so as to be rotatable relative to each other about a rotation shaft 217. The other end of the rear link member 216 is attached to the rear side surface of the guide support member 230 so as to be rotatable relative to the guide support member 230 about the rotation shaft 218. 230 is supported below the fixed operation panel 201.

  The rear link member 216 guides and supports the guide support member 230 together with the front link member 212 so as to be swingable between the forward swing position and the reverse swing position. At this time, the rear link member 216 is located behind the front link member 212 and operates in the same manner as the front link member 212.

  As shown in FIGS. 3A to 3C, the lock support member 250 is fixed to the rear side surface of the fixed operation panel 201. The lock support member 250 is provided with a lock member installation groove 251, and the lock member installation groove 251 is fitted with the shaft convex portion of the rotation shaft 218. The range in which the rear link member 216 rotates about the rotation shaft 217 is limited to the range of the lock member installation groove 251, so that the range in which the guide support member 230 swings is the forward swing position and the reverse swing position. Limited to range.

  At the front edge of the lock member installation groove 251, when the guide support member 230 moves to the forward swing position, the forward swing position lock member 252 is positioned so as to support the shaft convex portion of the rotating shaft 218 forward. It is attached (see FIG. 3 (b)). The forward swing position locking member 252 may be constituted by a leaf spring, for example.

  When the guide support member 230 is moved to the forward swing position, when the guide support member 230 is pulled forward, the forward convex position of the rotary shaft 218 is supported rearward by the forward swing position lock member 252. The guide support member 230 is pulled out so as to apply a further load forward. As a result, the shaft convex portion of the rotating shaft 218 rides on the forward swing position locking member 252 and passes forward. Similarly, when the guide support member 230 is moved from the forward swing position, the guide support member 230 is pushed so as to apply a further load to the rear.

  At the edge on the rear side of the lock member installation groove 251, when the guide support member 230 moves to the backward swing position, the reverse swing position lock member 253 is positioned so as to support the shaft convex portion of the rotating shaft 218 rearward. It is attached (see FIG. 3 (a)). The backward swing position lock member 253 is preferably constituted by a leaf spring, for example.

  When the guide support member 230 is moved to the backward swing position, when the guide support member 230 is pushed backward, the shaft convex portion of the rotating shaft 218 is supported forward by the backward swing position lock member 253. The guide support member 230 is pushed in so as to apply a further load to the rear. Thereby, the axial convex part of the rotating shaft 218 gets over the backward swing position lock member 253 and passes rearward. Similarly, when the guide support member 230 is moved from the backward swing position, the guide support member 230 is pulled out so as to apply a further load forward.

  A specific operation of the movable operation board 240 will be described with reference to FIGS. 3B and 3C. The space between the guide support member 230 and the movable operation board 240 is not fixed, and the movable operation board 240 can be moved along the guide support member 230 between the guide position and the use position. That is, the movable operation board 240 is guided by the guide support member 230 so as to be movable between the storage position and the use position.

  A stopper pin 231 is provided in front of the guide support member 230 on the side that fits with the side surface of the movable operation board 240. In addition, position restricting grooves 241 are provided on both side surfaces of the movable operation board 240. The position restricting groove 241 is fitted with the stopper pin 231, whereby the movement of the movable operation board 240 along the guide support member 230 is restricted between the storage position and the use position.

  A storage position restriction portion 242 is provided on the front side of the position restriction groove 241. The movable operation board 240 is restricted from moving further backward than the storage position by the storage position limiter 242 and the stopper pin 231 (see FIG. 3B).

  Further, a use position restricting portion 243 is provided on the rear side of the position restricting groove 241. The movable operation board 240 is restricted from moving further forward than the use position by the use position restricting portion 243 and the stopper pin 231 (see FIG. 3C).

(See (b)). The storage position detent member 244 may be constituted by a leaf spring, for example.

  When the stopper pin 231 is moved to the storage position, when the movable operation board 240 is pushed backward, a load is further applied to the rear from the state where the stopper pin 231 is supported forward by the storage position detent member 244. The movable operation board 240 is pushed in. As a result, the stopper pin 231 rides over the storage position detent member 244 and passes rearward. Similarly, when moving the movable operation board 240 from the storage position, the movable operation board 240 is pulled out so as to apply a further load forward.

  Similarly, a use position detent member 245 is attached to the rear edge of the position restriction groove 241 at a position where the stopper pin 231 is supported rearward when the movable operation board 240 moves to the use position ( (Refer FIG.3 (c)). The use position detent member 245 may be constituted by a leaf spring, for example.

  When the stopper pin 231 is moved to the use position, when the movable operation board 240 is pulled forward, the load is further applied forward from the state where the stopper pin 231 is supported rearward by the use position detent member 245. Pull out the movable operation board 240. As a result, the stopper pin 231 rides over the use position detent member 245 and passes forward. Similarly, when the movable operation board 240 is moved from the use position, the movable operation board 240 is pushed so as to apply a further load to the rear.

  As described above, when the movable operation board 240 is stored, the illumination unit 220 that illuminates the movable operation board 240 is used to connect the device or the connector of the device used during diagnosis, such as the probe connector 3 positioned below the fixed operation panel 201. By illuminating, the probe connector 3 can be visually recognized even in a dark place.

  Also, since the illumination unit 220 that illuminates the movable operation board 240 is also used for illumination of the device used during diagnosis of the probe connector 3 or the like or the connector of the device, the wiring to the illumination unit and the illumination unit is consolidated in one place. It becomes possible to do.

  Furthermore, when the illumination unit 220 performs illumination, the operation target corresponding to the form is illuminated according to the position of the movable operation board 240, so that the operator can guide the position of the operation target to be operated. Is possible.

  The direction of the illumination unit 220 only needs to be changed in accordance with the swing of the front link member 212. The link mechanism between the rear side of the fixed operation panel 201 and the rear side of the guide support member 230 includes the rear link member 216 and The configuration is not limited to the lock support member 250.

  For example, a guide member having a guide groove having a substantially horizontal direction as a longitudinal direction is fixed to the rear side surface of the fixed operation panel 201, a pin is provided on the rear side surface of the guide support member 230, and the guide groove and the pin are fitted. The guide support member 230 may be supported below the fixed operation panel 201. In this case, when the guide support member 230 moves to the forward swing position, the pin moves to the front end of the guide groove, and when the guide support member 230 moves to the reverse swing position, the pin moves to the guide position. Move to the rear end of the groove.

  Further, the illumination switch arranged on the fixed operation panel 201 may be linked with an exchange switch for instructing an exchange of an ultrasonic probe or an operation unit for instructing an freeze of an ultrasonic image. In the case of interlocking with the exchange switch, when the exchange switch is pushed, when the movable operation board 240 is accommodated (the guide support member 230 is moved to the backward swing position), the illumination unit 220 is also combined. It is good to make it illuminate. In the case of interlocking with the operation means for instructing the freeze, it is preferable to cause the illumination unit 220 to illuminate together when the movable operation board 240 is stored during the freeze.

(See (a)). The storage position detent member 644 may be constituted by a leaf spring, for example.

  When the stopper pin 631 is moved to the storage position, when the movable operation board 640 is pushed backward, a load is further applied to the rear from the state where the stopper pin 631 is supported forward by the storage position detent member 644. The movable operation board 640 is pushed in. Accordingly, the stopper pin 631 rides over the storage position detent member 644 and passes rearward. Similarly, when moving the movable operation board 640 from the storage position, the movable operation board 640 is pulled out so as to apply a further load forward.

  Similarly, a use position detent member 645 is attached to the rear edge of the position limiting groove 641 at a position where the stopper pin 631 is supported rearward when the movable operation board 640 moves to the use position ( (See FIG. 6 (c)). The use position detent member 645 may be constituted by a leaf spring, for example.

  When the stopper pin 631 is moved to the use position, when the movable operation board 640 is pulled forward, a load is applied further forward from the state where the stopper pin 631 is supported rearward by the use position detent member 645. Pull out the movable operation board 640. As a result, the stopper pin 631 rides over the use position detent member 645 and passes forward. Similarly, when moving the movable operation board 640 from the use position, the movable operation board 640 is pushed so as to apply a further load to the rear.

  As described above, the ultrasonic diagnostic apparatus according to the present embodiment can obtain the same effects as those of the ultrasonic diagnostic apparatus according to the first embodiment, and further, the structure thereof is simplified, thereby reducing the cost for production. It becomes possible.
