DETAILED DESCRIPTION

[0034] The following describes the embodiments based on the accompanying drawings. In addition, the present invention is not limited to the embodiments described herein. In all the drawings, the same symbols are marked on the same elements, and repeated descriptions are omitted. In this specification, unless otherwise specified, Figure 1 The directions indicated by the arrows X, Y, and Z are respectively designated as "front," "right," and "up," and the opposite directions are designated as "back," "left," and "down." The direction along the arrow Z coincides with the direction of gravity, i.e., the vertical direction.

[0035] (1) Overview of Implementation

[0036] The ultrasonic diagnostic device cart according to the embodiment includes: a base capable of carrying a portable ultrasonic diagnostic device; a handle connected to the base; a support column supporting the base so that it can be raised or lowered; a lifting operation unit for operating the base; a plurality of legs supporting the support column; and casters disposed on the legs. The handle includes a front handle disposed in front of the base and a rear handle disposed in rear of the base. The lifting operation unit includes a front operation unit disposed below the front handle and a rear operation unit disposed below the rear handle.

[0037] According to the above configuration, since the front operating portion is provided below the front handle, a user (e.g., an operator) can easily adjust the base height by operating the front operating portion with their fingers while placing their hands on the front handle. Furthermore, since the rear operating portion is provided below the rear handle, a user (e.g., a person transporting a cart for an ultrasonic diagnostic apparatus) can easily adjust the base height by operating the rear operating portion with their fingers while placing their hands on the rear handle.

[0038] In the embodiment, the front operating portion is a button located below the center of the front handle in the left-right direction. Pressing the button releases the lift lock of the base. The lift lock refers to a locked state in which the base is restricted from moving upwards or downwards. "Releasing the lift lock" allows the base to be raised or lowered.

[0039] According to the above structure, the user (e.g., operator) can release the lift lock of the base by pressing the button with his thumb while placing his hand on the left or right part of the front handle. Alternatively, the user can release the lift lock of the base by pressing the button with his thumbs while placing his hands on the left and right parts of the front handle.

[0040] In this embodiment, the rear operating unit is a lever located below the rear handle. Lifting the lever unlocks the base lift lock. With this configuration, a user (e.g., a cart carrier) can, for example, place their wrist on the rear handle and lift the lever with four fingers, excluding their thumb, to unlock the base lift lock.

[0041] In an embodiment, the rod serving as the rear operating portion may include two rod elements. The two rod elements are spaced apart in the left-right direction. The lifting lock of the base is released by lifting at least one of the two rod elements. According to this structure, a user (e.g., a person carrying a cart) can release the lifting lock of the base by lifting one rod element with four fingers other than the thumb while placing their wrists on the left or right part of the rear handle. In addition, the user can also release the lifting lock of the base by lifting each of the two rod elements with both hands while placing their wrists on the left and right parts of the rear handle.

[0042] In an embodiment, the pillar includes an upper pillar connected to a base, a lower pillar arranged below the upper pillar, and a gas spring arranged inside them. The pillar is a structure that is extended and retracted by inserting one of the upper pillar and the lower pillar into the other. One end of the gas spring is fixed to the base, and the other end of the gas spring is fixed to the lower pillar or a support body located below it. The gas spring includes a lock release pin. In the non-working state of the lock release pin, the gas spring fixes the base relative to the lower pillar. That is, the base is locked for lifting. In the working state of the lock release pin, the gas spring releases (releases the lifting lock) the fixation of the base relative to the lower pillar and applies a force to the base upward relative to the lower pillar. The front operating part or the rear operating part is operated to change the lock release pin from the non-working state to the working state.

[0043] According to the above configuration, when the lock release pin is activated by operating the front operating portion or the rear operating portion, the base can be suppressed from descending and can be raised by a slight force applied by the user.

[0044] In one embodiment, the handle includes side handles located on the left and right sides of the base. The handles are connected so as to surround the base. With this structure, for example, a user can hold the front or rear handle with one hand while holding a side handle with the other hand to fine-tune the position of the stroller or to swivel the stroller.

[0045] An ultrasonic diagnostic unit according to an embodiment includes the above-described ultrasonic diagnostic apparatus cart and a portable ultrasonic diagnostic apparatus mounted on a base of the cart.

[0046] Another embodiment of a cart for ultrasonic diagnostic equipment includes a base capable of carrying a portable ultrasonic diagnostic equipment; a handle connected to the base; a support column that supports the base in a liftable manner; a button for operating the base's lift; multiple legs that support the support column; and casters disposed on the legs. The handle includes a front handle disposed in front of the base. The button is located below the center of the handle in the left-right direction. Pressing the button unlocks the base's lift lock.

[0047] According to the above structure, a user (e.g., an operator) can release the base lift lock by pressing a button with his thumb while placing his hand on the left or right part of the front handle. Alternatively, a user (e.g., a cart carrier) can release the base lift lock by reaching to the front of the cart and pressing a button while standing at the rear of the cart.

[0048] In the ultrasonic diagnostic apparatus cart according to another embodiment, the handle may include side handles disposed on the left and right sides of the base, and a rear handle disposed on the rear side of the base.

[0049] An ultrasonic diagnostic unit according to another embodiment includes the ultrasonic diagnostic apparatus cart according to the above-mentioned other embodiment and a portable ultrasonic diagnostic apparatus mounted on a base of the cart.

[0050] (2) Detailed description of implementation methods

[0051] exist Figure 1 2 shows an ultrasonic diagnostic unit 10 according to the embodiment. This ultrasonic diagnostic unit is installed in a medical institution such as a hospital and is used for ultrasonic examination of a subject. Figure 1 It is a perspective view of the front and right side of the ultrasonic diagnostic unit 10 . Figure 2 It is a perspective view of the back and left side of the ultrasonic diagnostic unit 10 . Figure 3 It is a right side view of the ultrasonic diagnostic unit 10 . Figure 4 It is a top view of the ultrasonic diagnostic unit 10 .

[0052] The ultrasonic diagnostic unit 10 includes an ultrasonic diagnostic apparatus cart 12 and a portable ultrasonic diagnostic apparatus 100 (hereinafter referred to as the ultrasonic diagnostic apparatus 100) mounted on a base 20 of the cart 12. The ultrasonic diagnostic apparatus 100 is detachably mounted on the base 20 of the cart 12. Figure 5 、 Figure 6 ] shows the upper portion of the cart 12 in a state where the ultrasonic diagnostic apparatus 100 is removed.

[0053] like Figure 1 As shown, the ultrasonic diagnostic apparatus 100 is a notebook computer type. The ultrasonic diagnostic apparatus 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 with the hinge as an axis. Figures 1 to 4 1 and 2 show a state in which the display unit 106 is opened. The display unit 106 includes a display main body 106a having a display unit facing forward in the opened state.

[0054] The operation unit 102 includes a touch panel 102a and a button unit 102b. The button unit 102b includes an upper surface 102ba, a plurality of buttons, and a trackball 102bb. Figure 1 The trackball 102bb is located in the center in the left-right direction, so that the user can operate the trackball 102bb while resting his wrist on the palm rest 30. The right side of the operation unit 102 is provided with a connector 108a (port) for connecting a probe connector and an exhaust unit 110a for exhausting the air inside the ultrasonic diagnostic apparatus 100. Figure 2As shown, a connector portion 108 b (port) for connecting connectors of various devices and another exhaust portion 110 b are provided on the left side of the operation portion 102 .

[0055] like Figure 1 As shown, the cart 12 includes a base 20 , a handle 32 , a support column 22 , a lifting operation unit 50 , a support body 23 , two legs 24 , and four casters 26 .

[0056] The handle 32 is connected to the base 20. Figure 4 As shown, 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 at the rear of the base 20. The handles 32 are connected so as to surround the base 20. With this structure, for example, a user can finely adjust the position of the cart 12 or rotate the cart 12 by holding the front handle 32F or the rear handle 32R with one hand while holding the side handle 32S with the other hand.

[0057] The rear handle 32R is divided into two parts in the left-right direction by cutting away its central portion. The rear handle 32R is composed of a left rear handle element 32R and a right rear handle element 32R. The left rear handle element 32R extends rightward from the end of the left side handle 32S. The right rear handle element 32R extends leftward from the end of the right side handle 32S.

[0058] like Figure 4 As shown, the handle 32 is connected to the base 20 through the palm rest 30 and two connecting parts 33 and 34.

[0059] like Figure 1 As shown, the front handle 32F extends in the left-right direction. The two ends of the front handle 32F are bent in the oblique direction of the rear and the bottom and connected to the side handle 32S. Figure 5 、 Figure 6 As shown, the left and right side handles 32S respectively include a front portion 32S1 connected to the front handle 32F and inclined rearward 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 rises and slopes from the front toward the rear. The rear portion 32S3 of the side handle 32S rises and slopes sharply compared to its main body portion 32S2. Figure 4 As shown, the end portion of the rear portion 32S3 of the side handle 32S is bent toward the inner side in the left-right direction of the cart 12 and connected to the rear handle element 32R. Figure 3 As shown, the rear handle element 32R is disposed at a higher position than the front handle 32F.

[0060] The cross-sectional shape of the handle 32 is a flat oval. The front handle 32F and the rear handle 32R are arranged with their flat surfaces facing the vertical direction. The two side handles 32S are arranged with their flat surfaces facing the horizontal direction.

[0061] like Figure 3 As shown, the support 22 supports the base 20 in a liftable manner. The support 22 includes an upper support 22a connected to the base 20, a lower support 22b arranged below the upper support 22a, and a gas spring 64 arranged inside them (see FIG. Figure 7 ).like Figure 1 As shown, the width and thickness in the front-back direction of the upper support 22a are smaller than those of the lower support 22b. The support 22 is configured to be retractable by inserting the upper support 22a into the lower support 22b.

[0062] like Figure 5 As shown, the lifting operation unit 50 includes a front operation unit 50F and a rear operation unit 50R. The front operation unit 50F is a button located below the front handle 32F. The button 50F is located below the center of the front handle 32F in the left-right direction. The rear operation unit 50R is a rod located below the rear handle 32R. In particular, in this embodiment, the rear operation unit 50R is composed of two rod elements. By pressing the button 50F or lifting at least one of the two rod elements 50R, the telescopic lock (lift lock) of the support column 22 is released, allowing the base 20 to be raised or lowered.

[0063] With this configuration, the operator can, for example, adjust the height of the base 20 by pressing the button 50F with their thumb while placing their hand on the left or right side of the front handle 32F. Even when the operator is sitting on the right or left side of the front of the cart 12, they can still adjust the height of the base 20 by pressing the button 50F. Furthermore, the operator of the cart 12 can, for example, adjust the height of the base 20 by placing their wrists on the two rear handle elements 32R and lifting each of the two lever elements with their hands. The operator of the cart 12 can adjust the height of the base 20 by operating the two lever elements 50R according to their height, for example, and can carry the cart 12 by gripping the rear handle 32R.

[0064] like Figure 1 As shown, the support body 23 is disposed below the lower support column 22b. Two legs 24 are spaced apart in the left-right direction and connected to the support body 23. The two legs 24 extend in the front-to-back direction and support the support column 22 via the support body 23. Casters 26 are disposed on the bottom surfaces of each of the two legs 24 at both ends in the front-to-back direction.

[0065] like Figure 6As shown, the base 20 includes a restraint operating portion 90 for restraining the ultrasonic diagnostic apparatus 100 to the base 20 on its back surface, which is located below the gap between the two rear handle elements 32R. The restraint operating portion 90 is a rectangular parallelepiped member having a rotation axis 90a at its lower portion. The restraint operating portion 90 rotates about the rotation axis 90a and can assume an unrestrained state, in which its upper portion is away from the back surface of the base 20, and a restrained state, in which its upper portion is close to the back surface of the base 20.

[0066] When mounting the ultrasonic diagnostic apparatus 100 on the base 20, the restraint operating unit 90 is first placed in an unrestrained state. Then, the front of the ultrasonic diagnostic apparatus 100 is tilted downward, and with its front aligned with a predetermined position on the front of the base 20, the rear portion of the ultrasonic diagnostic apparatus 100 is placed on the base 20. The restraint operating unit 90 is then placed in a restrained state. Thus, the ultrasonic diagnostic apparatus 100 is restrained by the base 20. The front portion of the ultrasonic diagnostic apparatus 100 is restrained by the base 20 by a structure (e.g., a hook or groove) in which a portion of the front portion of the ultrasonic diagnostic apparatus 100 engages with the base 20. When the restraint operating unit 90 is placed in a restrained state from the unrestrained state, the rear portion of the ultrasonic diagnostic apparatus 100 is restrained by the base 20 by a pin protruding from the base 20 and inserted into a hole on the back of the ultrasonic diagnostic apparatus 100.

[0067] like Figure 5 As shown, the base 20 has a palm rest 30 connected to the front handle 32F. Figure 4 As shown in FIG. 1 , the palm rest 30 is arranged in front of the operation unit 102 of the ultrasonic diagnostic apparatus 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 ultrasonic diagnostic apparatus 100. Figure 3 As shown, the front handle 32F, the palm rest 30 and the upper surface 102ba of the operation portion of the ultrasonic diagnostic apparatus form a continuous upper surface.

[0068] like Figure 5 As shown, the base 20 includes a housing 82 and a top plate 80 mounted thereon. The housing 82 is formed in a dish shape and has an internal space. Figure 7 、 Figure 8 、 Figures 11 to 13 8 and 9 show a portion of the base 20 (the inner space of the housing 82) in a state where the top plate 80 is removed. A mechanism for raising and lowering the base 20 is arranged in the inner space of the housing 82.

[0069] As mentioned above, the gas spring 64 is arranged inside the support column 22. Figure 7As shown, one end of the gas spring 64 is fixed to the base 20. The other end of the gas spring 64 (not shown) is fixed to the lower support 22b (refer to Figure 1 ) or on the support 23 located therebelow. Figure 9 As shown, the gas spring 64 is provided with a lock release pin 64b. In the non-operating state of the lock release pin 64b (refer to Figure 9 ) , the gas spring 64 fixes the base 20 relative to the lower support 22b. The gas spring 64 is in the working state of the lock release pin 64b (refer to Figure 10 、 Figure 14 ) is released from the fixing of the base 20 to the lower support 22b, and the base 20 is forced upward relative to the lower support 22b. The button 50F (front operation unit) or the two lever elements 50R (rear operation units) are operated to change the lock release pin 64b from the non-operating state to the operating state.

[0070] According to this structure, when the button 50F or the two lever elements 50R are operated, the base 20 is biased upward relative to the lower support column 22b, thereby preventing unintended lowering of the base 20 and allowing the base 20 to be raised with a slight force from the user. By operating the button 50F or the two lever elements 50R, the user pushes the base 20 downward against the upward force applied to the base 20 by the gas spring 64, thereby lowering the base 20. Furthermore, the user can raise the base 20 by simply operating the button 50F or the two lever elements 50R, or by lightly lifting the base 20 in addition to operating the button 50F or the two lever elements 50R.

[0071] exist Figure 7 FIG shows the interior of the housing 82 when the button 50F is not pressed. Figure 8 FIG2 shows the interior of the housing 82 with the button 50F pressed. The base 20 includes a connecting rod 54, a pin swinging member 60, and a retaining portion 61 for the pin swinging member 60. The connecting rod 54 includes a connecting rod body 54a and a front end 54b. The connecting rod body 54a is a member extending in the front-to-back direction. The button 50F is connected to one end of the connecting rod body 54a. The front end 54b is connected to the other end of the connecting rod body 54a.

[0072] The housing 82 has a plurality of ribs on its bottom wall, and support portions 85 a , 85 b , and 85 c for the link body 54 a are formed by cutting away a portion of each rib.

[0073] The base 20 is provided with a tension spring 56. One end of the tension spring 56 is connected to a connecting portion 59 fixed to the link body 54a. The other end of the tension spring 56 is connected to a fixing portion 58 fixed to the bottom wall of the housing 82. Figure 7 、 Figure 8In the figure, for the convenience of illustration, the other end of the tension spring 56 is connected to the fixed portion 58 via a single dotted line (indicated by symbol 57), but in fact, the other end of the tension spring 56 is directly connected to the fixed portion 58. Figure 7 、 Figure 8 Although not shown, the tension spring 56 is in a slightly extended state regardless of whether the button 50F is pressed. Figure 8 ) and the state where the button 50F is not pressed ( Figure 7 ) compared to the tension spring 56, the tension spring 56 becomes more stretched.

[0074] The button 50F is disposed in a hole 82a provided in the base 20. The button 50F is biased forward by a tension spring 56 connected to the link body 54a. The button 50F and the base 20 include a restricting structure (e.g., a locking structure using a protrusion and a groove) that restricts excessive forward movement of the button 50F.

[0075] like Figure 8 As shown in FIG. 5 , when the button 50F is pressed, the connecting rod 54 moves forward, and the front end portion 54b of the connecting rod 54 pushes the pin swinging body 60. Figure 7 As shown, when the button 50F is released from being pressed, the button 50F returns to its initial position due to the biasing force of the tension spring 56 , so that the front end portion 54 b of the link 54 does not press the pin swinging member 60 .

[0076] The pin swinging member 60 is arranged inside the holding portion 61. Figure 9 As shown, the pin swinging member 60 has a substantially L-shape when viewed from the side. The pin swinging member 60 includes a front wall 60a, a bottom wall 60b, and two left and right side walls 60c ( Figure 9 Only one is shown in the figure). Holes are provided on the two side walls 60c for the passage of a shaft 62 extending in the left-right direction. The shaft 62 (for example, Figure 7 、 Figure 12 ) are fixed to the two side walls of the holding portion 61. The pin-use rocking member 60 is rockable about the shaft 62.

[0077] like Figure 9 As shown in FIG. 1 , the gas spring 64 includes a lock release pin 64b and a cylindrical portion 64a into which the lock release pin 64b enters. The lock release pin 64b is urged upward. Figure 9 As shown in FIG, the state in which the lock release pin 64b protrudes upward is the non-operating state of the lock release pin 64b. Figure 10 As shown, the state in which the lock releasing pin 64b is retracted into the cylindrical portion 64a is the operating state of the lock releasing pin 64b.

[0078] like Figure 9As shown, the pin swinging member 60 is lifted up by the lock release pin 64b in the initial position and becomes a forward-inclined posture. Figure 8 As shown, when the button 50F is pressed, the front end portion 54b of the link 54 pushes the front wall 60a of the pin swinging body 60 (refer to FIG. Figure 10 ). Thus, Figure 10 As shown, the pin swing member 60 swings, and the bottom wall 60b of the pin swing member 60 pushes the lock release pin 64b to change it to the working state. That is, by pressing the button 50F, the lock release pin 64b can be changed from the non-working state to the working state.

[0079] In addition, when the user stops pressing the button 50F (for example, releases the hand from the button 50F), the button 50F returns to the initial position by the tension spring 56. As a result, the front end portion 54b of the link 54 returns to the front (refer to Figure 9 ), so the pin swing body 60 returns to the initial position (reference Figure 9 ), the lock release pin 64b becomes non-operating state.

[0080] exist Figure 11 、 Figure 12 , the interior of the housing 82 is shown in a state where the two lever elements 50R are not operated. Figure 13 ] shows the interior of the housing 82 with the two lever elements 50R raised. Each of the two lever elements 50R includes an operating portion 50Ra and a connecting portion 50Rb for user operation. The base 20 includes a connecting rod 67, a retaining portion 69 for retaining the connecting rod 67, and a rear swinging member 68 coupled to the connecting rod 67.

[0081] The connecting rod 67 includes a rotational axis 67a extending in the left-right direction and two connecting portions 67b coupled to both ends of the rotational axis 67a. The rear ends of the two connecting portions 67b are rotatably connected to the ends of the connecting portions 50Rb of the two rod elements 50R. The rotational axis 67a of the connecting rod 67 passes through holes provided in the two side walls of the retaining portion 69 and is rotatably retained by the retaining portion 69.

[0082] The rear swing member 68 is arranged inside the holding portion 69. The rear swing member 68 includes a base portion 68a (see FIG. 1 ) coupled to the rotation shaft 67a of the link 67. Figure 9 ) and a stepped portion 68b connected to the base 68a. The front end of the stepped portion 68b is located above the bottom wall 60b of the pin swinging body 60. When the two lever elements 50R are not operated, as shown in FIG. Figure 9 As shown, the rear swing body 68 is in an upright position.

[0083] When the two rod elements 50R are lifted, as shown in FIG. Figure 13As shown in FIG. 1 , the connecting portion 50Rb of the two rod elements 50R rotates the two connecting portions 67b, thereby rotating the rotation shaft 67a. As a result, the rear swing body 68 becomes a tilted posture. Figure 14 As shown, the front end portion of the step portion 68b of the rear swing body 18 pushes the bottom wall 60b of the pin swing body 60 downward. Figure 14 As shown, the pin swing member 60 swings, and the bottom wall 60b of the pin swing member 60 pushes the lock release pin 64b to turn it into an operative state. That is, by lifting the two lever elements 50R, the lock release pin 64b can be turned from the inoperative state to the operative state.

[0084] In addition, when the user releases his hands from the two rod elements 50R, the two rod elements 50R return to their initial positions due to their own weight. As a result, the rear swing body 68 returns to the upright position (see FIG. Figure 9 ), so the pin swing body 60 returns to the initial position (reference Figure 9 ), the lock release pin 64b becomes non-operating state.

[0085] Next, an ultrasonic diagnostic unit according to another embodiment will be described. Figure 15 、 Figure 16 10A is a perspective view of another ultrasonic diagnostic unit 10A. In these figures, the display unit 106 of the ultrasonic diagnostic apparatus 100 is shown closed. The ultrasonic diagnostic unit 10A is different from the ultrasonic diagnostic unit 10 of the embodiment described above in that the structure of the cart 12A is different. Specifically, Figure 15 、 Figure 16 The cart 12A has a single button 50F at the front for raising and lowering the base 20, and the two rods at the rear are omitted. The cart 12A can be realized by omitting the two rods 50R and the mechanism connecting them of the cart 12 of the embodiment described above.

[0086] The ultrasonic diagnostic unit 10A of this alternative embodiment also achieves the same operational advantages as the ultrasonic diagnostic unit 10 described above. For example, the operator can adjust the height of the base 20 by pressing the button 50F with their thumb while placing their hand on the left or right side of the front handle 32F. Furthermore, the operator of the cart 12, for example, while positioned behind the cart 12, can reach forward and press the button 50F to adjust the height of the base 20.
