Best Mode for Carrying Out the Invention

[0014] The advantages and features provided by one or more embodiments of the present invention will be more fully understood from the following detailed description and the accompanying drawings. However, these drawings are for illustrative purposes only. Therefore, they are not intended to define the limits of the present invention. Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the scope of the present invention is not limited to the disclosed embodiments.

[0015] <00(00104>(First Embodiment) Referring to FIGS. 1 to 9, a first embodiment of the present invention will be described. Referring to FIGS. 1 to 7, the device configuration of the ultrasonic diagnostic apparatus 1 of the present embodiment will be described. First, referring to FIG. 1, the overall device configuration of the ultrasonic diagnostic apparatus 1 will be described. FIG. 1 is a perspective view showing the appearance of the ultrasonic diagnostic apparatus 1 of the present embodiment.

[0016] The ultrasonic diagnostic apparatus 1 is installed in an examination room of a medical facility such as a hospital. The ultrasonic diagnostic apparatus 1 applies an ultrasonic probe (not shown) that transmits and receives ultrasonic waves to a subject (the living body of a patient), transmits and receives ultrasonic waves from the ultrasonic probe, and generates ultrasonic image data from the received signal corresponding to the echo from the subject. The ultrasonic diagnostic apparatus 1 is used by users such as doctors and technicians and has a movable configuration so that it can move within a medical facility.

[0017] As shown in FIG. 1, the ultrasonic diagnostic apparatus 1 includes an ultrasonic diagnostic apparatus main body 10 and a cart unit 20 that can be used as a cart that can be optionally used by a user.

[0018] The ultrasound diagnostic device main unit 10 performs functions such as transmitting drive signals to the ultrasound probe, receiving electrical signals from the ultrasound probe, and generating ultrasound image data based on the received signals. The ultrasound diagnostic device main unit 10 can be detached from the cart unit 20 for portability. The ultrasound diagnostic device main unit 10 has a configuration that allows for the attachment and detachment of the ultrasound probe. The cart unit 20 is a movable trolley that displays the ultrasound image data generated by the ultrasound diagnostic device main unit 10 and accepts operation inputs. The cart unit 20 has a configuration that allows for the attachment and detachment of the ultrasound diagnostic device main unit 10.

[0019] Next, the device configuration of the ultrasound diagnostic device body 10 will be described with reference to Figures 2 to 4. Figure 2 is a perspective view showing a surface 11 of the ultrasound diagnostic device body 10. Figure 3 is a perspective view showing a surface 12 of the ultrasound diagnostic device body 10. Figure 4 is a perspective view showing the bottom surface 13 of the ultrasound diagnostic device body 10.

[0020] As shown in Figure 2, surface 11 is the surface that contacts the inner surface 221 of the support column 22, which will be described later, when the ultrasound diagnostic device body 10 is attached to the cart 20. Surface 11 is composed of a curved convex surface in plan view. The ultrasound diagnostic device body 10 has a gripping part 101 on its upper surface, which is used when attaching and detaching it from the cart 20 or when carrying the ultrasound diagnostic device body 10. The gripping part 101 is made of metal and is grounded as described later. As shown in Figure 3, surface 12 is the surface opposite to surface 11, and has three connectors 121 for connecting an ultrasound probe arranged side by side. Surface 12 also has a connector 122 for connecting the plug P at the end of a power cable, one end of which is connected to a commercial power supply.

[0021] As shown in Figure 4, the bottom surface 13 is the surface that faces the top surface of the main unit mounting section 21 (described later) when the ultrasound diagnostic device main unit 10 is attached to the cart section 20. The bottom surface 13 has two connection terminals 131 which are electrically connected to the connected terminals 212 provided on the main unit mounting section 21. In other words, the power lines and signal lines between the cart section 20 and the ultrasound diagnostic device main unit 10 are connected by the connection of the connected terminals 212 and the connection terminals 131. Here, the connection terminals 131 are electrically connected to the connected terminals 212. This makes it possible, for example, to input power from the ultrasound diagnostic device main unit 10 connected to commercial power, and to input image signals of ultrasound images, etc. It also makes it possible to input operation signals (operation signals based on the operation of the control console 232, described later) from the cart section 20 to the ultrasound diagnostic device main unit 10. Furthermore, if the ultrasound diagnostic device main unit 10 is not connected to commercial power, it is possible to input power from an external battery 253 (described later) to the ultrasound diagnostic device main unit 10.

[0022] Furthermore, the bottom surface 13 has two positioning holes 132 formed therein for inserting the guide pins 213 provided in the main body mounting section 21. The positioning holes 132 are cylindrical holes that guide the guide pins 213 inside and position them. In addition, the bottom surface 13 has a central rectangular mating area 13a, including the connection terminals 131, which is recessed inward from the main body 10 of the ultrasound diagnostic device. The mating area 13a has a shape that corresponds to the raised main body receiving surface 211 (Figure 5) of the main body mounting section 21. The connection configuration for grounding the ultrasound diagnostic device 1 will be described later.

[0023] Next, the configuration of the cart unit 20 will be described with reference to Figure 5. Figure 5 is a perspective view showing the external appearance of the cart unit 20.

[0024] As shown in Figure 5, the cart section 20 comprises a main body mounting section 21, a support column section 22, a work table 23, a main body guide section 24, and a caster section 25. The main body mounting section 21 is a base for mounting the ultrasound diagnostic device main body 10. When the ultrasound diagnostic device main body 10 is mounted, the main body mounting section 211 has a main body receiving surface 211 that corresponds to the fitting area 13a of the ultrasound diagnostic device main body 10. Two connection terminals 212 are provided on the main body receiving surface 211, at positions corresponding to each connection terminal 131 of the ultrasound diagnostic device main body 10. In addition, the main body mounting section 21 has two guide pins 213 on the support column section 22 side of the main body receiving surface 211, which will be described later. The guide pins 213 are guide pins that guide the ultrasound diagnostic device main body 10 so that it can be mounted in the appropriate position. The guide pins 213 are provided at positions corresponding to each positioning hole 132 of the ultrasound diagnostic device main body 10. The guide pin 213 is made of metal and is grounded as described later.

[0025] The support column 22 is erected at the end of the main body mounting section 21 and supports the workbench 23 connected to the support column 22. The support column 22 is composed of a concave curved surface in which the inner surface 221, extending from the end on the main body mounting section 21 side to a predetermined height (the height of the ultrasound diagnostic device main body 10), is recessed toward the outer surface 222 side. The inner surface 221 is the surface that faces the surface 11 of the ultrasound diagnostic device main body 10 when the ultrasound diagnostic device main body 10 is attached to the main body mounting section 21. The inner surface 221 is composed of a concave curved surface that follows (corresponds to) the convex curved surface of the surface 11 which is composed of a convex curved surface. The inner surface 221 has a metal surface and is grounded as described later. In addition, the support column 22 is provided with a fixing handle 223 at the predetermined height position mentioned above. The fixing handle 223 is made of metal and is grounded as described later. The fixing handle 223 presses down on the gripping portion 101 of the ultrasound diagnostic device body 10 from above, engaging and locking it in place when the ultrasound diagnostic device body 10 is attached to the body mounting portion 21.

[0026] The workbench 23 is a workbench for performing ultrasound diagnostics. The workbench 23 is equipped with a display 231 for displaying ultrasound image data, a control console 232, and a printer 234. The control console 232 receives user input related to the display, etc. The workbench 23 is also provided with a moving handle 233 for moving the cart unit 20 in the desired direction.

[0027] The main body guide section 24 is a guide wall that guides the convex curved surface of the aforementioned surface 11 to conform to the concave curved surface of the inner surface 221 when the ultrasound diagnostic device main body 10 is attached to the main body mounting section 21. The main body guide section 24 is formed in a slope shape, with the height of the wall gradually decreasing along the periphery of the main body mounting section 21 from both the left and right sides of the support column section 22.

[0028] The caster unit 25 comprises four legs 251, casters 252, and an external battery 253. The legs 251 extend radially from the main unit mounting section 21. The casters 252 are provided at the ends of each leg 251. The caster unit 25 allows the cart unit 20 and the ultrasound diagnostic device main unit 10 attached to the cart unit 20 to move in the forward, backward, left, and right directions by the rotation and swivel of each caster 252.

[0029] The external battery 253 is located below the support column 22 and the main unit mounting section 21, and supplies power to the ultrasound diagnostic device 1, the display 231, etc. The ultrasound diagnostic device main unit 10 is attached to the cart section 20, and power is supplied to the ultrasound diagnostic device main unit 10 from the commercial power supply via the plug P and connector 122. In this case, power is supplied to the ultrasound diagnostic device 1, the display 231, etc. from the commercial power supply, and the external battery 253 is charged by the supplied power. Alternatively, the ultrasound diagnostic device main unit 10 can be attached to the cart section 20, but power is not supplied from the commercial power supply. In this case, power is supplied to the ultrasound diagnostic device main unit 10, the display 231, etc. by the discharge of the external battery 253. At this time, the negative terminal of the external battery 253 is electrically connected to the grounded part of the cart section 20 and grounded. The grounded parts of the cart section 20 include the support column 22, the guide pin 213, the fixing handle 223, and the metal part 214, which will be described later. Furthermore, if the ground wire of the power cable is connected to the ultrasound diagnostic device body 10, the grounded parts of the ultrasound diagnostic device body 10 are grounded via the ground wire. The grounded parts of the ultrasound diagnostic device body 10 include the gripping part 101, the spring part 133 (described later), and the metal part 134. Therefore, the grounded parts of the cart part 20 and the grounded parts of the ultrasound diagnostic device body 10 are electrically connected. This improves the grounding performance of the ultrasound diagnostic device 1 and enhances its EMC performance. In addition, it can reduce noise such as image noise in ultrasound image data.

[0030] Next, the device configuration related to the grounding of the ultrasound diagnostic device 1 will be described with reference to Figures 6 to 8. Figure 6 is a schematic perspective view showing the connection of the guide pin 213 and the spring part 133. Figure 7 is a schematic side view showing the connection of the ultrasound diagnostic device body 10 and the cart part 20 via the fixed handle 223. Figure 8 is a schematic bottom view showing the connection of the ultrasound diagnostic device body 10 and the cart part 20 via the fixed handle 223.

[0031] As shown in Figure 6, the cart section 20 has a guide pin 213 and a metal section 214. The ultrasound diagnostic device body 10 has a positioning hole 132, a spring section 133, and a metal section 134. The metal section 214 schematically represents the metal part of the cart section 20 that is grounded, and is electrically connected to the guide pin 213. The guide pin 213 has a tapered section 2131 at its tip that becomes thinner (the diameter of the cross-section decreases) towards the tip. The guide pin 213 is fixedly and electrically connected to the metal section 214 with a low resistance value. The spring section 133 is a metal plate-shaped spring located deep inside the positioning hole 132. The spring section 133 is arranged, for example, to have a plate surface perpendicular to the axial direction (up and down direction = direction of gravity) of the positioning hole 132, and is fixedly and electrically connected to the metal section 134 with a low resistance value. The metal part 134 schematically represents the metal part of the ultrasound diagnostic device body 10 that is to be grounded, and is electrically connected to the spring part 133.

[0032] When the ultrasound diagnostic device body 10 is attached to the cart section 20, the guide pin 213 is inserted into the positioning hole 132, and its tip abuts against the spring section 133. At this time, a portion of the weight of the ultrasound diagnostic device body 10 is applied to the spring-shaped metal section 114, so the restoring force of the spring-shaped metal section 114 acts in the axial direction (downward) of the guide pin 213. As a result, the degree of pressure contact between the spring-shaped metal section 114 and the guide pin 213 increases, creating a good electrical connection that is low in resistance and does not come loose. The metal section 214 and the metal section 134 are grounded to each other.

[0033] As shown in Figures 7 and 8, the cart section 20 has a fixed handle 223, a pivot point 224, a spring section 225, and a fixing section 226. The fixed handle 223 is rotatable by the user manually, as shown by the arc-shaped arrow in Figure 7, with the pivot point 224 as its axis. By rotating, the fixed handle 223 fits (joins) and locks onto the gripping section 101 on the ultrasound diagnostic device body 10. As a result, the cart section 20 and the ultrasound diagnostic device body 10 are electrically connected. The gripping section 101 is electrically connected to the metal section 134.

[0034] The fixed handle 223 is rotatable, but has a spring portion 225 and a fixed portion 226 to reduce electrical resistance between the support column 22 and the fixed handle 223. The spring portion 225 is made of metal and is positioned at a location corresponding to the point of action when the fixed handle 223 rotates. One end of the spring portion 225 is fixedly and electrically connected to the fixed portion 226, and the other end is electrically in contact with the inner surface 221, which is the surface of the support column 22, so as to slide. The inner surface 221 is electrically connected to the metal portion 214. The fixed portion 226 is made of metal and is grounded, and one end of the spring portion 225 is fixedly and electrically connected to it. The inner surface 221 of the support column 22, which the spring portion 225 touches, has a metal surface or is plated with metal so that it can conduct electricity. Due to its restoring force, the spring portion 225 remains electrically connected to the inner surface 221 even when the fixed handle 223 moves. Therefore, the inner surface 221 and the fixed handle 223 (gripping portion 101) are always in electrical contact and grounded via the spring portion 225.

[0035] Next, the procedure for attaching the ultrasound diagnostic device body 10 to the cart section 20 will be explained with reference to Figure 9. Figure 9 shows the first stage of attachment of the ultrasound diagnostic device body 10.

[0036] First, as shown in Figure 5, the cart section 20 is erected. At this time, the fixing handle 223 provided on the support column section 22 is in a flipped-up position. Then, the user brings the surface 11 of the ultrasound diagnostic device body 10 and the inner surface 221 of the support column section 22 into contact with each other. Specifically, the surface 11 and the inner surface 221 come into contact with each other such that the convex curved surface of the surface 11 conforms to (corresponds to) the concave curved surface of the inner surface 221.

[0037] Next, as shown in Figure 9, the user places the ultrasound diagnostic device body 10 on the main body mounting section 21 of the cart section 20, while maintaining a state in which the surface 11 and the inner surface 221 are in contact with each other. At this time, each guide pin 213 is inserted into each positioning hole 132 of the bottom surface 13. The guide pins 213 are pressed against and compressed against the spring section 133 by the weight of the ultrasound diagnostic device body 10. Due to the restoring force of the spring section 133, the guide pins 213 (metal section 214) and the spring section 133 (metal section 134) are electrically connected and grounded. At the same time, each connection terminal 131 is electrically connected to each connected terminal 212.

[0038] Next, as shown in Figure 1, the user tilts the fixed handle 223, which is in the flipped-up position. This causes the fixed handle 223 to fit into and lock onto the ultrasound diagnostic device body 10. In this way, the attachment of the ultrasound diagnostic device body 10 to the cart section 20 is completed. With the fixed handle 223 fitted, the spring section 225 electrically connects and grounds the support column section 22 and the gripping section 101.

[0039] As described above, according to this embodiment, the ultrasound diagnostic device 1 comprises an ultrasound diagnostic device body 10 and a cart unit 20. The cart unit 20 is detachable from the ultrasound diagnostic device body 10. The cart unit 20 has a metal guide pin 213. The guide pin 213 is positioned on the body receiving surface 211 of the ultrasound diagnostic device body 10 and is electrically connected to a metal part 214, which is the first metal part to be grounded in the cart unit 20. The ultrasound diagnostic device body 10 has a positioning hole 132 as a hole and a spring part 133, which is a first metal spring part. The guide pin 213 is inserted into the positioning hole 132. The spring part 133 is positioned inside the positioning hole 132 and is electrically connected to a metal part 134, which is the second metal part to be grounded in the ultrasound diagnostic device body 10, and receives the guide pin 213. Therefore, since screws are not used to attach or detach the ultrasound diagnostic device body 10 to the cart section 20, ease of attachment and detachment between the ultrasound diagnostic device body 10 and the cart section 20 can be maintained. At the same time, a good electrical connection state can be formed between the guide pin 213 and the spring section 133 with low resistance and without disconnection. Thus, the grounding between the ultrasound diagnostic device body 10 (metal section 134) and the cart section 20 (metal section 214) can be improved, and the EMC performance of the ultrasound diagnostic device 1 can be improved. Furthermore, image noise in ultrasound image data can be reduced.

[0040] The positioning hole 132 is located in the fitting region 13a of the bottom surface 13 of the ultrasound diagnostic device body 10. The spring portion 133 is pressed against the guide pin 213 from the bottom surface 13 side, and a restoring force acts in the axial direction of the guide pin 213. Therefore, the weight of the ultrasound diagnostic device body 10 can be used to more easily electrically connect the spring portion 133 and the guide pin 213. In addition, the degree of pressure contact between the guide pin 213 and the spring portion 133 can be increased, creating a good electrical connection state with lower resistance and preventing disconnection, and improving grounding.

[0041] The ultrasound diagnostic device body 10 has a metal gripping portion 101 that is grounded. The cart portion 20 has a movable metal fixed handle 223 and a spring portion 225 as a second spring portion. The fixed handle 223 is fitted into the gripping portion 101. The spring portion 225 is electrically connected to the fixed handle 223 and the inner surface 221 of the cart portion 20, which is the metal housing surface to be grounded. The spring portion 225 slides against the inner surface 221 in accordance with the movement of the fixed handle 223. As a result, a good electrical connection state with low resistance and no disconnection can be formed between the fixed handle 223 and the inner surface 221 at all times. Thus, the grounding performance between the ultrasound diagnostic device body 10 (grip portion 101) and the cart portion 20 (support portion 22) can be improved, and the EMC performance of the ultrasound diagnostic device 1 can be improved.

[0042] The fixed handle 223 is rotatable around the pivot point 224. The spring portion 225 is positioned at a location corresponding to the point of action of the fixed handle 223 and slides against the inner surface 221 in accordance with the movement of the fixed handle 223. As a result, a good electrical connection state can be formed between the fixed handle 223 and the inner surface 221, which is always low resistance and does not come loose. Thus, the ground contact between the ultrasound diagnostic device body 10 (gripping portion 101) and the cart portion 20 (support column portion 22) can be improved.

[0043] (Second Embodiment) A second embodiment of the present invention will be described with reference to Figure 10. Figure 10 is a schematic perspective view showing the connection of the guide pin 213 and the spring portion 135 of this embodiment.

[0044] The apparatus configuration of this embodiment uses the same ultrasound diagnostic apparatus 1 as in the first embodiment, but with the ultrasound diagnostic apparatus body 10 replaced by the ultrasound diagnostic apparatus body 10a. Therefore, the same reference numerals are used for parts that are the same as in the ultrasound diagnostic apparatus 1 of the above embodiment, and their descriptions are omitted. The main differences will be described.

[0045] As shown in Figure 10, the ultrasound diagnostic device body 10a has a spring section 135 and a screw 136 instead of a spring section 133. The spring section 135 is a metal, bell-shaped spring, and is fixedly and electrically connected to the metal section 134 by screwing in a metal screw 136. The spring section 135 has two opposing leaf springs 1351 and a connecting section 1352. The connecting section 1352 is a plate-shaped connecting section for fixing the screw 136, and the leaf spring 1351 is connected to its lower part. A gap 1353 for inserting a guide pin 213 is formed between the leaf spring 1351 and the connecting section 1352.

[0046] When the ultrasound diagnostic device body 10 is placed on the cart section 20, each guide pin 213 is inserted (guided) into the gap 1353 of the spring section 135 within each positioning hole 132. At this time, a portion of the weight of the ultrasound diagnostic device body 10 is applied to the spring section 135. Since the guide pin 213 has a tapered section 2131 at its tip, as it is inserted, the restoring force from the leaf spring 1351 increases, and the degree of pressure contact with the spring section 135 increases. This restoring force acts from a direction perpendicular to the axial direction of the guide pin 213 (horizontal direction). As a result, a good electrical connection is formed between the spring section 135 (metal section 134) and the guide pin 213 (metal section 214). Therefore, the ultrasound diagnostic device body 10 (metal section 134) and the cart section 20 (metal section 214) are grounded.

[0047] As described above, according to this embodiment, the spring portion 135 is bell-shaped. Therefore, a good electrical connection state can be formed between the guide pin 213 and the spring portion 135 that is lower in resistance and does not come loose.

[0048] Furthermore, the positioning hole 132 is located on the bottom surface 13 of the ultrasound diagnostic device body 10. The guide pin 213 has a tapered portion 2131 that becomes thinner towards the tip. The spring portion 135 is pressed against the guide pin 213 from the bottom surface 13 side, and a restoring force acts in the direction perpendicular to the axial direction of the guide pin 213. As a result, a good electrical connection can be formed between the spring portion 135 (metal portion 134) and the guide pin 213 (metal portion 214). Thus, the grounding between the ultrasound diagnostic device body 10 (metal portion 134) and the cart portion 20 (metal portion 214) can be improved.

[0049] The above description of the embodiment is merely an example of an ultrasound diagnostic apparatus according to the present invention, and is not limited thereto.

[0050] For example, in the above embodiment, the cart section 20 may be configured to include a positioning spacer on the main body mounting section 21. The positioning spacer guides the ultrasound diagnostic device body 10 so that the surface 11 of the ultrasound diagnostic device body 10 corresponds to the inner surface 221 of the support column section 22 of the cart section 20. In plan view, the positioning spacer is, for example, crescent-shaped, and the curved portion is formed to correspond to the surface 12 of the ultrasound diagnostic device body 10. This makes the electrical connection between the ultrasound diagnostic device body 10 and the cart section 20 easier.

[0051] Furthermore, in the above embodiment, the cart section 20 may be configured to have an anti-slip sheet on the inner surface 221 of the support column section 22. This makes it less likely for the ultrasound diagnostic device body 10 to shift when it is attached to the cart section 20, due to the anti-slip sheet. Therefore, rattling of the ultrasound diagnostic device body 10 when the cart section 20 is moved can be further suppressed.

[0052] Furthermore, in the above embodiment, for example, the surface 11 of the ultrasound diagnostic device body 10 may be configured to have a concave curved surface. In this case, the inner surface 221 of the support column 22 of the cart portion 20 has a convex curved surface corresponding to the concave curved surface.

[0053] While embodiments of the present invention have been described and illustrated in detail, the disclosed embodiments are for illustrative and illustrative purposes only and are not limiting. The scope of the present invention should be interpreted by the terms of the appended claims. [Explanation of symbols]
