An ultrasonic diagnostic apparatus and a gantry according to this embodiment will be described in detail with reference to the drawings.

FIG. 1 is an external view showing an ultrasonic diagnostic apparatus 1 according to the present embodiment from the rear right side of the apparatus. As shown in FIG. 1, an ultrasonic diagnostic apparatus 1 includes a housing 2, a plurality of (four in this example) casters 3, an operation unit 5 operated by a user, various parts such as an affected area of a patient and the state of the apparatus. It comprises a display unit 6 for displaying, an operation unit 5, a lifter 4 for adjusting the vertical position of the display unit 6, and the like. In this embodiment, the housing 2 and the lifter 4 correspond to the “apparatus body” of the ultrasonic diagnostic apparatus 1 . Moreover, in this embodiment, the caster 3 corresponds to the "moving part" of the present invention.

The housing 2 is a substantially box-shaped outer body, and accommodates various components that constitute the ultrasonic diagnostic apparatus 1 . In the present embodiment, the rear panel 23 of the housing 2 is configured to be detachable from the other portion (peripheral surface) of the housing 2 (see FIG. 4). In the present embodiment, in order to facilitate attachment and detachment of the rear panel 23, for example, a claw or (the claw is fitted) is attached to the outer portion of the rear panel 23 or the corresponding portion (back side) of the housing 2. A latch structure with a groove is provided. The back panel 23 prevents dust from entering the housing 2 and serves as an exterior decorative cover that maintains the appearance. Further, as shown in FIG. 1, the back panel 23 is provided with a plurality of slits 23c (long holes) for releasing air discharged from a fan 83, which will be described later, to the outside of the apparatus.

Referring to FIG. 2, a power supply unit 8 for supplying electric power to each part of the ultrasonic diagnostic apparatus 1 is arranged in the lower part of the housing 2 of the ultrasonic diagnostic apparatus 1 . The power supply unit 8 includes a transformer (not shown) or the like, converts (converts AC/DC, voltage, etc.) a current supplied from a power outlet (outlet) through a power cable 10 described later, and converts the converted current to ultrasonic waves. It is supplied to each part of the diagnostic device 1 .

On the other hand, an electric circuit 82 for various signal processing and control is arranged in the upper part of the housing 2 . The electric circuit 82 is arranged in a space surrounded by a metal frame 81 (a plurality of metal plates), which will be described later. The electric circuit 82 is operated by electric power supplied from the power supply section 8 and has a function as a drive signal generation section that generates a drive signal for causing an ultrasonic probe (not shown) to transmit ultrasonic waves. A drive signal generated by the electric circuit 82 is transmitted to the ultrasonic probe through a signal line (not shown) connected to the electric circuit 82 . The electrical circuit 82 also performs various electrical processes such as generating an ultrasound image based on the signal received from the ultrasound probe through the signal line.

Further, a metal frame 81 is provided between the power supply unit 8 and the electric circuit 82 inside the housing 2 as a shield member for blocking electric noise. As shown in FIG. 2, the metal frame 81 is formed by assembling plate-like members (metal plates) into a frame-like or substantially box-like shape. The metal frame 81 is arranged so that its outer surface is close to or in contact with the inner wall of the housing 2 . Thus, the metal frame 81 accommodates the electric circuit 82, and also prevents the electric circuit 82 and the ultrasonic probe from being affected by malfunctions caused by noise components generated from the power supply unit 8 and the power cable 10, which will be described later. It has the function of electrically protecting (shielding) the circuit 82 and blocking it from electrical noise. The metal frame 81 also serves to physically protect other parts housed in the housing 2 from impacts caused by external forces. Various other components are accommodated in the housing 2, and will be referred to as appropriate in the description of FIG. 4, which will be described later.

Referring to FIG. 1 again, each caster 3 is, for example, a wheel having a shaft and a rubber tire attached to the outer circumference of the wheel. The shaft of the caster 3 is held by a bearing (not shown) of a caster holding portion 31 provided on the tip end side of the leg portion 21 projecting from the lower portion of the housing 2 . The caster holding part 31 is rotatable below the tip side of the corresponding leg part 21, so that the orientation (advancing direction) of the caster 3 can be freely changed. Further, the caster holding portion 31 is provided with a rotation stop 31a for fixing the orientation (advancing direction) of the caster 3 and a wheel stop (not shown in FIG. 1) for preventing the rotation of the caster 3. By the user operating these, it is possible to prevent the ultrasonic diagnostic apparatus 1 from moving with respect to the floor surface.

The lifter 4 is arranged to extend upward from the upper surface (top plate) of the housing 2 . The lifter 4 is vertically extendable (see double arrow Z) and horizontally rotatable. The operating section 5 and the display section 6 are attached to the upper portion of the lifter 4 . For this reason, the lifter 4 expands and contracts in the vertical direction to adjust the operating unit 5 and the like to a height position that is easy for the user to handle. It can be adjusted to a comfortable rotation position. That is, the lifter 4 has a function of changing the height of the entire device and a function of movably supporting the operation section 5 and the display section 6 . The lifter 4 also has a function of accommodating (passing through) the above-described signal lines that transmit signals between the electric circuit 82 and the ultrasonic probe.

The operation unit 5 includes a trackball 51 and various key switches 52 operated by a user (see also FIG. 3A, etc.), and an ultrasonic probe for irradiating an affected area of a patient with ultrasonic waves and receiving reflected waves. has a connector or the like to which a terminal of is connected. Such connectors are connected to the signal lines described above. The operation unit 5 also includes a probe holder 53 for holding or housing an ultrasonic probe when not in use, a gel holder 55 for housing a bottle of ultrasonic diagnostic gel (not shown) applied to a patient during diagnosis, and an ultrasonic probe. A cable hanger 56 for hanging a cable connected to various devices such as a cable hanger is provided. In this embodiment, the probe holder 53 corresponds to the "holding part" of the present invention.

The display unit 6 is, for example, a touch panel type liquid crystal display, and displays various images such as an ultrasonic image of the state of the affected area based on the received reflected waves and a setting screen for setting parameters of the apparatus. An arm portion 61 for adjusting the angle of the display surface of the display portion 6 is attached to the rear surface of the display portion 6 . (see FIG. 2, etc.).

By the way, when using the ultrasonic diagnostic apparatus 1 as described above, it may be necessary to move the ultrasonic diagnostic apparatus 1 while the power cable 10 is connected. At this time, if the power cable 10 hangs down between the two casters 3, 3 on the rear side, the power cable 10 is caught in the rotation of the casters 3, and the power cable 10 and the like are damaged. could have occurred. This problem will be described below with reference to FIG. 3A.

FIG. 3A is a top view of a hospital room in which the ultrasonic diagnostic apparatus 1 is installed. In the example shown in FIG. 3A, two beds B are arranged in a hospital room (on the floor surface F), and the ultrasonic diagnostic apparatus 1 is arranged between the beds B. In the example shown in FIG. In addition, as shown in FIG. 3A, this ultrasonic diagnostic apparatus 1 is provided with a power cable 10 on the back side of the housing 2, and the plug of the power cable 10 is an outlet as a power outlet provided on the wall surface W. Power is supplied by plugging into the OL, and it operates.

Here, let us consider a case in which patients are seated on beds B, B, respectively, and ultrasonic images of affected areas of the patients are successively captured. In this case, for the purpose of facilitating imaging and operation and showing the captured image to the patient, the ultrasonic diagnostic apparatus 1 uses the functions of the casters 3 described above to move the floor surface between the beds B while the power cable 10 is connected. It can be moved on F (see direction of movement indicated by T in FIG. 3A). However, conventionally, when moving the ultrasonic diagnostic apparatus 1 in this way, there is a problem that the power cable 10 tends to interfere with the casters 3 . In other words, if the power cable 10 is caught in the casters 3 during movement as described above, troubles such as damage to the power cable 10 and its connecting portion may occur.

As a solution to this problem, caster holders 31 and casters 3 are attached to the bottom (bottom surface) of housing 2 without providing legs 21 so that casters 3 do not protrude from housing 2 in the lateral direction. A configuration in which they are provided directly is also conceivable. However, with such a configuration, the distance between the casters 3 becomes narrower, so the ultrasonic diagnostic apparatus 1 becomes less stable during installation and movement, and the ultrasonic diagnostic apparatus 1 tends to fall over. There is

In view of this problem, the inventors of the present invention have made intensive research and found that in the ultrasonic diagnostic apparatus 1 of the type equipped with the casters 3, the power cable 10 is located above the apparatus (upper portion) as shown in FIG. 3B, for example. The inventors have found that it is desirable to have a configuration in which the side is pulled outward. By adopting such a structure, it is possible to prevent the intermediate portion (electric wire) of the power cable 10 from reaching the floor surface F, thereby solving problems such as entanglement with the casters 3 . On the other hand, in the ultrasonic diagnostic apparatus 1, if the power supply unit 8 connected to the power cable 10 is also arranged above the apparatus, various electrical noises generated from the power supply unit 8 may interfere with the imaging or generation of ultrasonic images. may affect the performance, etc. of the For this reason, conventionally, in the integrated ultrasonic diagnostic apparatus as described above with reference to FIGS. It is common technical knowledge that the cable 10 is arranged at the bottom of the device.

In addition, in many portable ultrasonic diagnostic apparatuses that are lightweight and small and designed for portability, the ultrasonic diagnostic apparatus and a power supply section that supplies power to the apparatus are separated. In many cases, such a portable ultrasonic diagnostic apparatus is detachably mounted on the upper side of a pedestal provided with casters, and the power supply unit and power cable are arranged on the lower side of the pedestal. By arranging in this way, it is possible to ensure the performance of capturing or generating an ultrasound image. However, even with such a configuration, the power cable tends to interfere with the casters when the gantry is moved, so if the power cable is caught in the casters, the above-described troubles may occur.

Therefore, in the ultrasonic diagnostic apparatus 1 of the present embodiment, the power supply cable 10 connected to the power supply unit 8 is connected to the power supply unit 8 while maintaining the configuration in which the power supply unit 8 is arranged on the lower side of the apparatus as in the conventional art. A configuration is adopted in which a drawer portion is provided to be pulled out from the upper side of the diagnostic device 1 . Hereinafter, the configuration of the drawer portion will be described in detail with reference to FIG. 4 and subsequent drawings.

FIG. 4 is a diagram showing a state in which the rear panel 23 shown in FIG. 1 is removed. A connector 24 into which a female terminal of the power cable 10 is inserted (detachable) is provided at the bottom of the housing 2 . The connector 24 is electrically coupled with the power supply section 8 described above. Therefore, the power cable 10 is connected to the connector 24 at the bottom of the housing 2 to supply the power supply section 8 with power (for example, current of AC 100 V) supplied from the outlet OL (see FIG. 3B).

Further, as shown in FIG. 4 , a plurality of (three in this example) fans 83 are provided on the rear side of the housing 2 for cooling the electronic components in the ultrasonic diagnostic apparatus 1 . Furthermore, a metal frame 81 (metal plate) as a shield member is arranged in a frame shape on the rear side of the housing 2 so as to surround the fans 83 . A flange-shaped take-out portion 20 for putting the power cable 10 thereon and taking it out of the housing 2 (pulling it out of the device) is provided on the upper part of the metal frame 81 (the back panel 23 is attached). (see also Figure 5, which was published). In this embodiment, the take-out portion 20 and the opening 23a of the rear panel 23 correspond to the "drawer portion" of the present invention. Also, the opening 23a corresponds to the "first opening" of the present invention.
In the present embodiment, the drawer part is arranged in the upper part of the housing 2 (above the middle height between the bottom and the upper part of the housing 2).

Furthermore, a plurality of claw-like clamps 25 for holding (supporting) or fixing the power cable 10 and guiding it to the take-out portion 20 are provided on the left side of the metal frame 81 in FIG. In the present embodiment, the clamp 25 is arranged along the wall surface of the housing 2 (the rear panel 23 in this example), holds the power cable 10 on the metal frame 81, and functions as a guide portion that guides the power cable 10 to the extraction portion 20. responsible for The take-out portion 20 and the clamp 25 can be formed by processing the metal frame 81, or may be attached to the metal frame 81 with a member made of other material such as resin.

In the present embodiment, the power cable 10 is held by each clamp 25 so as to be fastened upward along the left side surface of the metal frame 81 in FIG. It is bent to the right and pulled out to the outside of the device through the opening 23a (see FIGS. 1 and 5) on the upper side of the take-out portion 20 and the rear panel 23. As shown in FIG.

As described above, in the present embodiment, a routing configuration for routing the power cable 10 inside the housing 2 is provided, and a configuration is provided to pull out the power cable 10 from the upper portion of the housing 2 . With such a configuration, the length of the power cable 10 pulled out to the outside of the device can be appropriately adjusted to effectively prevent the extra power cable 10 from reaching the floor surface F, and the power cable 10 can be pulled out of the caster. 3 can be solved.

As another example of the guide portion, a concave groove (not shown) may be provided in the metal frame 81 to guide the power cable 10 . 4 is also provided on the right side of the metal frame 81 in FIG. The power cable 10 may be pulled out from the opening 23a) of the portion 20 and the rear panel 23. FIG. With such a configuration, for example, even if the power cable 10 is considerably long, the length of the power cable 10 that is pulled out of the device can be appropriately adjusted.

Further, in the present embodiment, the power cable 10 is arranged so as to pass between the metal frame 81 (metal plate) and the rear panel 23 . According to this configuration, while suppressing the interference between the power cable 10 and the caster 3 described above, electrical noise generated from the power cable 10 is blocked by the metal plate 81, and the housing 2 such as the electrical circuit 82 Influence on internal electronic components is prevented. Moreover, since a part of the power cable 10 (that is, the cord part until it is pulled out to the outside of the housing 2) is covered with the back panel 23, the appearance is not spoiled.

In the above example, the guide portion for guiding the power cable 10 to the lead-out portion (extraction portion 20, etc.) is arranged along the back panel 23 (that is, the outer peripheral surface on the back side) of the housing 2, and the power cable 10 is fixed or A configuration was adopted in which a holding clamp 25 was provided. As another example, the connector 24 (see FIG. 4) for connecting the power cable 10 to the power supply unit 8 may be provided near the drawer (for example, at a position facing the opening 23a of the rear panel 23).

The arrangement and configuration of the drawer portions described above is an example, and various other arrangements and configurations are possible. That is, in the above configuration example, the drawer portion is provided on the rear side (rear surface) of the housing 2. The user-friendly drawer position can be selected. For example, the drawer portions may be provided on the left and right side surfaces of the housing 2 and on the upper surface (top plate portion), or may be provided on the lifter 4 . It should be noted that when the pull-out portion is provided in the lifter 4 , it is preferable to dispose the shield member described above inside the lifter 4 as well.

Further, the height position of the drawer portion is not particularly limited as long as it is on the upper side of the apparatus main body (the height position at which the power cable 10 does not contact the floor surface F). However, if the position of the drawer portion is too high, there is a problem that the ultrasonic diagnostic apparatus 1 tends to overturn when the power cable 10 is pulled by some external force or the like. For this reason, the upper limit of the height position of the drawer portion is set to the position of the probe holder 53 described above. That is, from the viewpoint of preventing the ultrasonic diagnostic apparatus 1 from overturning, etc., it is desirable that the height position of the drawer portion is provided at a position lower than the probe holder 53 .

On the other hand, the lower limit of the height position of the drawer portion is set to a position that ensures a minimum height at which the power cable 10 is less likely to get entangled with the casters 3 or to be stepped on. From this point of view, it is desirable that the height position of the drawer is above the midpoint of the distance from the contact point between the floor surface F and the caster 3 to the lower surface of the operation unit 5 .

As described above, when the drawer portion is provided on the upper side of the main body of the apparatus, for example, when a person trips over the power cable 10 or touches a surrounding object and the power cable 10 is pulled strongly, the power cable 10 may be pulled. There is a problem that the ultrasonic diagnostic apparatus 1 falls more easily than before. As a countermeasure, a part of the power cable 10 (for example, a connecting part with the outlet OL, or an intermediate part, etc.) may be configured with a magnet plug. By configuring the power cable 10 in such a manner, it is possible to prevent the ultrasound diagnostic apparatus 1 from falling over in the case described above by physically disconnecting the power cable 10 .

Depending on the environment in which the ultrasonic diagnostic apparatus 1 is placed (the position of the bed B, the distance from the outlet OL, etc.), it may be better to pull out the power cable 10 from the lower side of the housing 2 as in the conventional case. can be obtained. For this reason, as an additional or optional function, an opening 23b (see dotted line in FIG. 1) as a second opening is also provided on the lower side of the rear panel 23 so that the power cable 10 can be passed through the lower opening. (The user can select). In the present embodiment, as described above, the back panel 23 can be easily attached and detached due to the latch structure. Therefore, by providing a plurality of openings in the back panel 23 through which the power cable 10 can be pulled out, the user's convenience can be further enhanced. can be done.
