DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments will be described with reference to the drawings. Note that the present disclosure is not limited to the embodiments described herein. In all drawings, the same elements are given the same reference numerals, and duplicate explanations will be omitted. In this specification, unless otherwise specified, the directions indicated by arrows X, Y, and Z in FIG. 1 are referred to as "front," "right," and "up," respectively, and the opposite directions are referred to as "rear," "left," and "down." The direction along arrow Z coincides with the direction in which gravity acts, i.e., the vertical direction.

[0014] (1) Overview of the embodiment An ultrasound diagnostic unit according to an embodiment includes a portable ultrasound diagnostic device, a base on which the portable ultrasound diagnostic device is placed, a handle connected to the base, a support column supporting the base, a plurality of legs supporting the support column, and casters arranged on the legs. The handles include a front handle arranged in front of the base, side handles arranged on the left and right sides of the base, and a rear handle arranged at the rear of the base. The handles are connected to each other so as to surround the periphery of the base. Each of the two side handles includes a front portion connected to the front handle and sloping rearward and downward, and a main body portion extending rearward from the rear end of the front portion.

[0015] According to the above configuration, the handles are provided around the base, allowing the user to access the handles and move the ultrasonic diagnostic unit regardless of the user's position relative to the ultrasonic diagnostic unit. For example, the user can fine-tune the position of the ultrasonic diagnostic unit or rotate it by holding the front or rear handle with one hand and the side handle with the other. Furthermore, the two side handles are provided at a relatively low position, allowing the sides of the portable ultrasonic diagnostic device to be exposed. This allows easy access to connectors (ports) on the sides of the portable ultrasonic diagnostic device.

[0016] In an embodiment, the base includes a palm rest located in front of the operation unit of the portable ultrasound diagnostic device and in the center in the left-right direction. The palm rest is located between the front handle and the operation unit of the portable ultrasound diagnostic device. The front handle, the palm rest, and the operation unit of the portable ultrasound diagnostic device form a continuous top surface. With this configuration, a user (e.g., a surgeon) can operate the portable ultrasound diagnostic device by resting their wrists on the front handle and the palm rest.

[0017] In the embodiment, the rear handle is provided at a higher position than the front handle. With this configuration, the rear handle is positioned higher when the front handle is located at a relatively low position, taking into consideration that a user (e.g., an operator) will be seated and operate the portable ultrasound diagnostic device. Therefore, when a user (e.g., a carrier) carries the ultrasound diagnostic unit by holding the rear handle, the carrier can easily carry the ultrasound diagnostic unit.

[0018] In this embodiment, the main bodies of the two side handles are inclined upward from the front to the rear. With this configuration, when a probe holder, a holder for holding a jelly container, a holder for holding a tray, or the like is attached to the main body of the side handle, the object held by the holder faces diagonally forward. This allows a user (e.g., a surgeon) to easily access the object held by the holder.

[0019] In the embodiment, the cross-sectional outline of the handle has a flattened ellipse shape. The front handle and rear handle are arranged so that their flat surfaces face up and down. The two side handles are arranged so that their flat surfaces face left and right. With this configuration, a user can move the ultrasound diagnostic unit by holding the front handle or rear handle with their hands pressed against the flat surface on top of the handle. Furthermore, because the flat surfaces of the two side handles face left and right, it is possible to prevent the side handles from protruding left and right.

[0020] In this embodiment, the rear handle is divided into left and right sections by a cutout in the center. The rear handle consists of a left rear handle element and a right rear handle element. The base has an operation unit (referred to as a restraint operation unit) for restraining the portable ultrasound diagnostic device to the base on its back surface facing at least one of the gap area between the two rear handle elements and the area below that gap. With this configuration, the gap area between the two rear handle elements allows the user to easily access the restraint operation unit through the gap area.

[0021] In an embodiment, the support supports the base so that it can be raised and lowered. The ultrasound diagnostic unit is provided with a push button for operating the raising and lowering of the base. The push button is located below the center in the left-right direction of the front handle. Pressing the push button releases the lift lock of the base. Note that the lift lock refers to a locked state in which the base is restricted from being raised or lowered and cannot be raised or lowered. "The lift lock is released" means that the base can be raised or lowered.

[0022] According to the above configuration, a user (e.g., a surgeon) can release the lift lock of the base by pressing the push button with their thumb while placing their hands on the left or right side of the front handle. Also, a user can release the lift lock of the base by pressing the push button with the thumbs of both hands while placing both hands on the left and right sides of the front handle.

[0023] An ultrasound diagnostic device cart according to an embodiment includes a base on which a portable ultrasound diagnostic device is placed, a handle connected to the base, a support column supporting the base, a plurality of legs supporting the support column, and casters disposed on the legs. The handles include a front handle disposed in front of the base, side handles disposed on the left and right sides of the base, and a rear handle disposed at the rear of the base. The handles are connected to each other so as to surround the periphery of the base. Each of the two side handles includes a front portion connected to the front handle and sloping rearward and downward, and a main body portion extending rearward from the rear end of the front portion.

[0024] According to the above configuration, the handles are provided around the base, so that the user can access the handles and move the cart regardless of the user's position relative to the cart. Furthermore, the two side handles are provided at a relatively low position, so that the sides of the portable ultrasound diagnostic device can be opened when the portable ultrasound diagnostic device is placed on the base of the cart. This allows easy access to connectors (ports) on the sides of the portable ultrasound diagnostic device.

[0025] In the cart for an ultrasound diagnostic apparatus according to the embodiment, the rear handle is located at a higher position than the front handle. With this configuration, the rear handle is located at a higher position when the front handle is located at a relatively low position, taking into consideration that a user (e.g., a surgeon) will be seated and operate the portable ultrasound diagnostic apparatus. Therefore, when a user (e.g., a carrier) carries the cart by holding the rear handle, the carrying operation can be easily performed.

[0026] (2) Details of the embodiment FIG. 1 shows an ultrasonic diagnostic unit 10 according to an embodiment. This ultrasonic diagnostic unit 10 is installed in a medical institution such as a hospital and is used for ultrasonic examinations of subjects. FIG. 1 is a perspective view of the front and right side of the ultrasonic diagnostic unit 10. FIG. 2 is a perspective view of the back and left side of the ultrasonic diagnostic unit 10.

[0027] As shown in Fig. 1, the ultrasonic diagnostic unit 10 includes an ultrasonic diagnostic device cart 12 and a portable ultrasonic diagnostic device 100 (hereinafter referred to as ultrasonic diagnostic device 100) placed on a base 20 of the cart 12. The ultrasonic diagnostic device 100 is detachably mounted on the base 20 of the cart 12. Fig. 13 shows a right side view of the cart 12 with the ultrasonic diagnostic device 100 removed. Fig. 14 shows a plan view of the cart 12 with the ultrasonic diagnostic device 100 removed.

[0028] As shown in FIG. 1, the ultrasound diagnostic device 100 is a notebook computer type. The ultrasound diagnostic device 100 includes an operation unit 102 and a display unit 106. The operation unit 102 and the display unit 106 are connected to each other by a hinge. The display unit 106 can be closed toward the operation unit 102 around the hinge. All of FIGS. 1 to 6 show the display unit 106 in an open state. The display unit 106 includes a display main body 106a having a display portion that faces forward when the display unit 106 is open. Note that FIGS. 9 to 12 show the ultrasound diagnostic unit 10 with the display unit 106 closed.

[0029] As shown in FIG. 1, the operation unit 102 includes a touch panel 102a and a button unit 102b. The button unit 102b includes an upper surface 102ba, multiple buttons, and a trackball 102bb. The multiple buttons are represented in FIG. 1 by multiple small squares, circles, or the like. The trackball 102bb is located in the center in the left-right direction, allowing the user to operate the trackball 102bb with their wrists resting on the palm rest 30. The right side of the operation unit 102 is provided with a connector unit 108a (port) to which a probe connector is connected, and an exhaust unit 110a through which air that has cooled the inside of the ultrasound diagnostic device 100 is exhausted. As shown in FIG. 2, the left side of the operation unit 102 is provided with a connector unit 108b (port) to which connectors of various devices are connected, and another exhaust unit 110b.

[0030] As shown in FIG. 1, the cart 12 includes a base 20, a handle 32, a support 22, a lifting operation unit 50, a support body 23, two legs 24, and four casters 26.

[0031] The handle 32 is connected to the base 20. As shown in Fig. 14, the handle 32 includes a front handle 32F disposed in front of the base 20, side handles 32S disposed on the left and right sides of the base 20, and a rear handle 32R disposed behind the base 20. The handles 32 are connected so as to surround the periphery of the base 20.

[0032] As shown in Figure 14, the rear handle 32R is divided in the left-right direction by a cutout in the center. The rear handle 32R consists of a left rear handle element 32R and a right rear handle element 32R. The left rear handle element 32R extends to the right from the end (transition portion 32TR) of the left side handle 32S. The right rear handle element 32R extends to the left from the end (transition portion 32TR) of the right side handle 32S.

[0033] As shown in FIG. 14, the handle 32 is connected to the palm rest 30 and the base 20 by two connecting portions 33 and 34.

[0034] As shown in FIG. 3, the support columns 22 support the base 20 so that it can be raised and lowered. The support columns 22 include an upper support column 22a (see FIG. 3) to which the base 20 is connected, a lower support column 22b arranged below the upper support column 22a, and a gas spring (not shown) arranged inside the upper and lower support columns 22a and 22b. The upper support column 22a has a smaller width and a smaller thickness in the front-to-rear direction than the lower support column 22b. The support columns 22 are configured to expand and contract when the upper support column 22a is inserted into the lower support column 22b. FIGS. 1 to 6 show the cart 12 with the support columns 22 contracted, i.e., with the base 20 at or near its lowest position. When the support columns 22 are extended, the upper support column 22a (see FIG. 3) protrudes significantly from the lower support column 22b.

[0035] As shown in Fig. 1, the support 23 is disposed below the lower support 22b. The two legs 24 are disposed at a distance in the left-right direction and are connected to the support 23. Each of the two legs 24 extends in the front-rear direction and supports the support 22 via the support 23. Casters 26 are disposed on the bottom surface of both ends of the leg 24 in the front-rear direction.

[0036] As described above, a gas spring is disposed inside the support column 22. One end of the gas spring is fixed to the base 20, and the other end of the gas spring is fixed to the lower support column 22b or the support 23 located below it. The gas spring is equipped with an unlocking pin. When the unlocking pin is in a non-operating state, the gas spring fixes the base 20 to the lower support column 22b. When the unlocking pin is in an operating state, the gas spring releases the fixation of the base 20 to the lower support column 22b and urges the base 20 upward relative to the lower support column 22b.

[0037] As shown in FIG. 1, the cart 12 includes a lifting / lowering operation unit 50 located below the center of the front handle 32F in the left-right direction. The lifting / lowering operation unit 50 is a push button. When the push button 50 is pressed, it changes the unlocking pin of the gas spring from an inactive state to an active state. That is, while the push button 50 is pressed, the unlocking pin is in an active state, and the lock on the extension / retraction of the support 22 (the fixation of the base 20 to the lower support 22b) is released, allowing the base 20 to be raised or lowered.

[0038] The user can lower the pedestal 20 by pressing the push button 50 downward against the upward bias of the gas spring against the pedestal 20. The user can also raise the pedestal 20 by simply pressing the push button 50 or by additionally lightly lifting the pedestal 20. According to this embodiment, the surgeon can adjust the height of the pedestal 20 by pressing the push button 50 with their thumb while placing their hand on the left or right part of the front handle 32F, for example.

[0039] As shown in FIG. 14, the base 20 includes a palm rest 30 connected to the front handle 32F. As shown in FIG. 7, the palm rest 30 is disposed in front of the operation unit 102 of the ultrasound diagnostic device 100 and in the center in the left-right direction. The palm rest 30 is located between the front handle 32F and the operation unit 102 of the ultrasound diagnostic device 100. As shown in FIG. 5, the front handle 32F, the palm rest 30, and the top surface 102ba of the operation unit of the ultrasound diagnostic device form a continuous top surface. This allows the surgeon to operate the ultrasound diagnostic device 100 by resting their wrists on the front handle 32F and the palm rest 30.

[0040] As shown in FIG. 2 (or FIGS. 11 and 12), the base 20 is provided with a restraint operation unit 90 for restraining the ultrasound diagnostic apparatus 100 to the base 20 on its rear surface facing the area below the gap area between the two rear handle elements 32R. The restraint operation unit 90 is a rectangular parallelepiped member with a rotation shaft 90a at its bottom. The restraint operation unit 90 rotates around the rotation shaft 90a to assume an unrestrained state in which its upper portion is separated from the rear surface of the base 20 and a restrained state in which its upper portion is close to the rear surface of the base 20.

[0041] When mounting the ultrasonic diagnostic apparatus 100 on the base 20, first, the restraining operation unit 90 is set to the non-restraining state. Then, the front of the ultrasonic diagnostic apparatus 100 is tilted downward, and the rear of the ultrasonic diagnostic apparatus 100 is placed on the base 20 with the front of the ultrasonic diagnostic apparatus 100 aligned with a predetermined position at the front of the base 20. Thereafter, the restraining operation unit 90 is changed to the restraining state. This restrains the ultrasonic diagnostic apparatus 100 to the base 20. The front of the ultrasonic diagnostic apparatus 100 is restrained to the base 20 by a structure (e.g., a hook and a groove) that allows a part of the front of the ultrasonic diagnostic apparatus 100 to be hooked onto the base 20. When the restraining operation unit 90 is changed from the non-restraining state to the restraining state, a pin protrudes from the base 20 and is inserted into a hole in the back of the ultrasonic diagnostic apparatus 100, thereby restraining the rear of the ultrasonic diagnostic apparatus 100 to the base 20.

[0042] In this embodiment, a gap area is provided between the two rear handle elements 32R, allowing the user to access the restraint operating unit 90 through the gap area, making it easy to attach and detach the ultrasound diagnostic device 100.

[0043] As shown in FIG. 1, the front handle 32F extends in the left-right direction. Both ends of the front handle 32F are bent diagonally backward and downward and connected to the side handles 32S. As shown in FIGS. 5 and 6, each of the left and right side handles 32S includes a front portion 32S1 connected to the front handle 32F and inclined backward and downward, a main body portion 32S2 extending rearward from the rear end of the front portion 32S1, and a rear portion 32S3 extending rearward from the rear end of the main body portion 32S2. The main body portion 32S2 of the side handle 32S is inclined upward from the front to the rear. The rear portion 32S3 of the side handle 32S is inclined upward more steeply than the main body portion 32S2. As shown in FIG. 7, the end of the rear portion 32S3 of the side handle 32S is bent inward in the left-right direction of the cart 12 and connected to the rear handle element 32R. As shown in FIGS. 5 and 6, the rear handle element 32R is provided at a higher position than the front handle 32F.

[0044] As shown in Figure 7 (or Figure 14), in plan view, the handle 32 has a rounded transition portion 32TF between the front handle 32F and the side handle 32S, and similarly, a rounded transition portion 32TR between the side handle 32S and the rear handle element 32R.

[0045] The handle 32 has a cross-sectional outer shape of a flattened ellipse around its entire circumference. Figure 7 shows cross section AA of the front handle 32F, cross section BB of the side handle 32S, and cross section CC of the rear handle 32R. The front handle 32F and the rear handle 32R are arranged so that their flat surfaces face up and down. The two side handles 32S are arranged so that their flat surfaces face left and right.

[0046] One or both of the two side handles 32S may be fitted with, for example, a probe holder, a holder for holding a jelly container, or a holder for holding a tray. An example of the attachment position of the probe holder 200 is shown in phantom lines in FIGS. 1, 6, and 7. An example of the probe holder 200 is shown in FIG. 8. The probe holder 200 includes one or more holder elements 202 and a hook 204. The probe head 300 is inserted into and supported by the holder element 202. The probe holder 200 is attached to the side handle 32S by hooking the hook 204 of the probe holder 200 onto the side handle 32S.

[0047] According to the embodiment described above, the handle 32 is provided around the base 20, so that the user can access the handle 32 and move the ultrasonic diagnostic unit 10 regardless of the user's position relative to the ultrasonic diagnostic unit 10. For example, the user can fine-tune the position of the ultrasonic diagnostic unit 10 or rotate the ultrasonic diagnostic unit 10 by holding the front handle 32F or the rear handle 32R with one hand and the side handle 32S with the other hand. For example, the user can carry the ultrasonic diagnostic unit 10 by holding the rear handle 32R.

[0048] Furthermore, according to the embodiment described above, the handles 32 are connected and the corners of the handles 32 (transition portions 32TF, 32TR) have a rounded shape, which prevents white coats and the like from getting caught on the handles 32.

[0049] Furthermore, according to the embodiment described above, as shown in FIGS. 5 and 6 , the main bodies 32S2 of the two side handles 32S are provided at a relatively low position, thereby enabling the side of the ultrasonic diagnostic apparatus 100 to be opened. Note that "provided at a relatively low position" means that the main bodies 32S2 of the two side handles 32S are provided at a position lower than the top surface of the operation unit 102 of the ultrasonic diagnostic apparatus 100. That is, the main bodies 32S2 of the two side handles 32S extend parallel or approximately parallel to the top surface of the operation unit 102 of the ultrasonic diagnostic apparatus 100. Furthermore, in a direction (approximately the vertical direction) perpendicular to the direction in which the main bodies 32S2 of the two side handles 32S extend, the main bodies 32S2 of the two side handles 32S are provided at a lower position than the top surface of the operation unit 102 of the ultrasonic diagnostic apparatus 100. Therefore, the side of the operation unit 102 of the ultrasonic diagnostic apparatus 100 can be opened. This allows easy access to the connectors 108a and 108b of the ultrasonic diagnostic device 100, and prevents the exhaust sections 110a and 110b from being blocked.

[0050] Furthermore, according to the embodiment described above, the rear handle 32R is provided at a higher position than the front handle 32F. Therefore, in consideration of the operator operating the ultrasound diagnostic device 100 while sitting, when the front handle 32F is located at a relatively low position, the rear handle 32R is positioned higher. This makes it easier for the user to transport the ultrasound diagnostic unit 10 by holding the rear handle 32R, for example.

[0051] 5 and 6, the main bodies 32S2 of the two side handles 32S are inclined upward from the front to the rear. Therefore, when a holder such as the probe holder 200 is attached to the main body 32S2 of the side handle 32S, an object held by the holder (e.g., the probe head 300) faces diagonally forward. This allows the surgeon to easily access the object held by the holder.

[0052] According to the embodiment described above, the handle 32 has a cross-sectional outer shape that is a flattened ellipse over its entire circumference. This increases the rigidity of the handle 32. The front handle 32F and the rear handle 32R are arranged so that their flat surfaces face up and down, allowing the user to move the ultrasound diagnostic unit 10 by holding the handle with their hands in close contact with the upper flat surface of the front handle 32F or the rear handle 32R. The two side handles 32S are arranged so that their flat surfaces face up and down, reducing the amount of protrusion of the side handles 32S in the left and right directions compared to when the side handles 32S are arranged so that their flat surfaces face up and down.
