Description

Ultrasonic diagnostic apparatus 【0001】 The present invention relates to an ultrasonic diagnostic apparatus for displaying biological information. 【0002】 When a plurality of people view an image simultaneously on an ultrasonic diagnostic apparatus, if the display screen of the monitor is limited to one direction, it is necessary to face the monitor towards multiple people, and there may be a case where more people cannot view the image. In contrast, in Patent Document 1, a display device is used in which two liquid crystal displays are laminated back-to-back, so that it can be viewed from both the front and back sides. 【0003】 Japanese Patent No. 3794901 【0004】 As described above, some ultrasonic diagnostic apparatuses are provided with a monitor for displaying various medical information and medical devices such as ultrasonic probes that come into contact with patients for diagnosis. When using such an ultrasonic diagnostic apparatus, a doctor acquires a patient's biological information through the display area of the monitor while also using various medical devices to approach the patient and obtain the patient's biological information through direct actions on the patient such as palpation and interrogation. Therefore, the doctor may take an appropriate posture depending on the patient's position, posture, observation site, etc., such as a sitting position (sitting on a chair) or a standing position (standing posture). On the other hand, since it is mainly for a technician to acquire a patient's biological information through the display area of the monitor, there is little need to be in a sitting position, and a standing position is common. Therefore, while it is necessary for a doctor to change the height of the display area to be gazed at according to both sitting and standing postures, it has been required that the display area be located at an appropriate height when in a standing position for a technician. 【0005】 An object of the present invention is to provide an ultrasonic diagnostic apparatus capable of realizing a display area height suitable for both sitting and standing postures and only a standing posture. 【0006】The present invention relates to an ultrasound diagnostic apparatus for acquiring and processing a patient's biological information, comprising a housing having a front portion that extends vertically in part, and a back portion located on the opposite side of the front portion with respect to the normal direction of the front portion, wherein display areas are provided on at least the front portion and the back portion, and when viewed from the normal direction, the front display area, which is the display area on the front portion, and the back display area, which is the display area on the back portion, overlap at least. 【0007】 The front display area and the rear display area may be separate. The rear monitor having the rear display area may be detachably attached to the housing. Preferably, the rear monitor having the rear display area is fixed to the housing. Preferably, the surface of the rear part including the rear display area is flat. Preferably, the display panel includes a front display area and a rear display area. Preferably, the vertical length of the front display area is greater than the vertical length of the rear display area, and the lower end of the rear display area is located vertically above the lower end of the front display area. Preferably, the vertical length of the front display area is greater than the vertical length of the rear display area, and the lower end of the front display area is located vertically at the same position as the lower end of the rear display area, or vertically above the lower end of the rear display area. 【0008】 The amount of information displayed in the rear display area may be the same as the amount of information displayed in the area of the front display area corresponding to the installation area of the rear display area. Preferably, the width of the rear display area is less than or equal to the width of the front display area. 【0009】 The housing is provided with first gripping portions extending vertically, located at the right and left ends, respectively, and the width between the first gripping portions is preferably 30 cm to 57 cm. The vertical installation range of the first gripping portions preferably overlaps with at least a portion of the length of the front display area, or at least a portion of the length of the rear display area. The rear side is provided with a second gripping portion extending laterally and intersecting the vertical direction. 【0010】Preferably, the housing portion has a first region in which at least a part of the front display area and the rear display area are provided, and a third region below the first region and inclined toward the front portion in the direction normal to the first region. Preferably, the housing portion has a second region below the third region and in the direction normal to the rear portion, and the length of the first region in the direction normal to is smaller than the length of the second region in the direction normal to. 【0011】 The rear display area preferably displays content that is shown in at least a portion of the front display area. The content displayed in at least a portion of the front display area preferably is a GUI. 【0012】 Preferably, the GUI for the front display area is positioned vertically below the front display area, and the GUI for the back display area is positioned vertically above the back display area, or across the entire back display area. 【0013】 The GUI in the front display area preferably displays GUIs that are not displayed in the GUI in the rear display area. The GUI in the rear display area preferably displays GUIs that are not present in the GUI in the front display area. 【0014】 It is preferable that input to the GUI of the front display area takes precedence over input to the GUI of the rear display area. It is preferable that input to the GUI of the rear display area takes precedence over input to the GUI of the front display area. 【0015】 It is preferable that when the GUI of the front display area is operated, the operation content is reflected in the GUI of the rear display area, or when the GUI of the rear display area is operated, the operation content is reflected in the GUI of the front display area. 【0016】 When the GUI of the front display area is operated, it is preferable that the operation result displayed in the front display area is displayed in the rear display area, or when the GUI of the rear display area is operated, it is preferable that the operation result displayed in the rear display area is displayed in the front display area. 【0017】 According to the present invention, it is possible to achieve a display area height suitable for both sitting and standing postures, as well as for standing postures only. 【0018】 This is a side view of an ultrasound diagnostic device.

The ultrasound diagnostic device 10 processes and displays the ultrasound image obtained by applying the transducer to the patient. In addition to being an ultrasound diagnostic device, the ultrasound diagnostic device 10 can be used as various ultrasound diagnostic devices, such as surgical devices. 【0020】The ultrasound diagnostic device 10 comprises a housing 11 and a handle 12. The housing 11 includes a front portion 21 and a back portion 23 located on the upper side of the vertical direction V, a side portion 22 located at the end of the front portion 21 with respect to a lateral direction H that intersects (specifically, perpendicularly) the normal direction N of the front portion 21 and also intersects (specifically, perpendicularly) the vertical direction V, and a base 28 provided at the lower part of the vertical direction V. The side portion 22 has a right end portion 22a and a left end portion 22b. A connector (not shown) for an ultrasound probe, which is a contact used for ultrasound diagnosis, is installed on the front side of the base 28. A processor (not shown) that controls the transmission and reception of signals from the ultrasound probe and generates ultrasound images may be provided inside the base 28. 【0021】 The handle 12 has a gripping portion 12a (first gripping portion) that is grasped by the user when moving the ultrasound diagnostic device 10. The gripping portion 12a extends in the vertical direction V and is attached to the right end 22a and the left end 22b, respectively. Four casters 13 are provided on the caster mounting plate 28a at the bottom of the base 28, below the housing portion 11 in the vertical direction V. These four casters 13 allow the entire ultrasound diagnostic device 10 to be moved. The number of casters is not limited to four, as long as it is sufficient to balance the entire ultrasound diagnostic device 10. Furthermore, it is preferable to use casters with a larger diameter (e.g., 6 inches) than the commonly used 5-inch casters. By using such large-diameter casters, the ultrasound diagnostic device 10, which has a vertically elongated shape as a whole, can be transported stably without losing balance. Furthermore, the housing 11 is the basic part of the ultrasound diagnostic device 10, and if there is a separate component that is separated (for example, the rear monitor 30 described later), the housing 11 and the separate component will differ in size and other characteristics. 【0022】As shown in Figure 11, the housing portion 11 has a first region R1 in which at least a part of the front display area 26 and the rear display area 27 are provided, a third region R3 below the first region R1 and inclined toward the front portion 21 in the normal direction N with respect to the first region R1, and a second region R2 below the third region and inclined toward the rear portion 23 in the normal direction N. The first region R1 includes a planar portion 21a provided on the front portion 21 and extending in the vertical direction V. The third region R3 includes an inclined portion 21b provided on the front portion 21 and inclined at a predetermined angle with respect to the vertical direction V. The second region R2 includes a base 28. The caster mounting plate 28a of the base 28 has a length Db in the lateral direction H (width direction) that is longer than the length Da in the normal direction N (depth direction). Furthermore, the length Da of the caster mounting plate 28a of the base 28 in the normal direction N (depth direction) is longer than the length D2 of the second region (see Figure 15). 【0023】 Because the third region R3 is inclined toward the front portion 21, the physician can bring the inclined portion 21b of the third region R3, where the GUI and other information are displayed, closer to the physician even while standing, thus improving the physician's operability. In addition, by folding the third region, the physician can perform touch operations on the operating surface of the inclined portion 21b of the third region R3 without bending the palm of the hand towards the panel surface of the inclined portion 21b, thus improving the physician's operability. Therefore, by folding the third region R3 toward the first region R1, the loss of operability is reduced and operability is improved compared to the case where the third region R3 is not folded. It is preferable that no display area such as an operating surface is provided on the back portion 23 side of the third region. 【0024】 In the ultrasound diagnostic apparatus 10 shown in Figure 11, the third region R3 is connected to the first region R1. In this case, it is preferable that the inclined portion 21b of the third region R3 is connected to the first region R1 with a connection angle θ of 10° to 50°. Alternatively, as shown in Figure 12, the first region R1 and the third region R1 may be separated in relation to the front portion 21. 【0025】The back surface 23 is located on the opposite side of the front surface 21 with respect to the normal direction N of the front surface 21. The housing 11 may also be equipped with a control unit (processor) for processing and displaying biological information. The contact probe used for ultrasound diagnosis is held in a contact probe holding section 24 located below the gripping section 12a in the vertical direction V. The front surface 21, which defines the normal direction, has both a flat surface and an inclined surface that are flat, not curved or curved. 【0026】 The display area 25 is provided on at least the front portion 21 and the back portion 23, and displays biological information. Specifically, when viewed from the normal direction N, it is preferable that the front display area 26, which is the display area 25 on the front portion 21 side, and the back display area 27, which is the display area 25 on the back portion 23 side, at least overlap. The length L1 in the vertical direction V of the front display area 26 is greater than the length L2 in the vertical direction V of the back display area 27. Also, the lower end 27a of the back display area 27 is located above the lower end 26a of the front display area 26 in the vertical direction V. 【0027】 As a result, on the front side 21, the user can assume both sitting and standing positions, like a doctor. This allows for the acquisition of not only the patient's biological information, such as medical record information, through the front display area 26, but also the acquisition of the patient's biological information by directly interacting with the patient, such as through palpation and questioning. On the other hand, on the back side 23, the user can assume only a standing position, like a technician. This allows for the acquisition of the patient's biological information through the back display area 27 while standing. 【0028】 Furthermore, in the ultrasound diagnostic device 10, a display area 25 is integrally provided on the front 21 and back 23 of the housing 11, which is used for acquiring and processing biological information. Therefore, even when a user observes the display area 25, the housing 11 does not get in the way, and the housing 11 does not restrict the observer's standing position. On the other hand, as in Patent Document 1, when the monitor observed by a doctor such as an anesthesiologist and the management device managed by the monitor observer are separate, the management device becomes an obstacle when observing the monitor, restricting the monitor observer's standing position. 【0029】Furthermore, the width W3 between the gripping parts 12a (see Figures 2 and 3) is preferably 30 cm to 57 cm as an effective inner width. This effective inner width is preferably set to encompass, for example, the shoulder width of an adult Japanese person (for example, greater than the shoulder width of a petite woman but less than or equal to the maximum shoulder width of a man), which is 380 mm to 460 mm. By setting the width W3 between the gripping parts 12a as described above, when transporting the ultrasound diagnostic device 10, the width W3 between the gripping parts 12a is within the range of the transporter's shoulder width, thereby reducing the load on the transporter's shoulder muscles and allowing the ultrasound diagnostic device 10 to be transported safely. 【0030】 Alternatively, instead of positioning the lower end 27a of the rear display area 27 higher in the vertical direction V than the lower end 26a of the front display area 26, the lower end 26a of the front display area 26 may be positioned higher in the vertical direction V than the lower end 27a of the rear display area 27, as shown in Figure 13. In this case, even when the ultrasound diagnostic device 10 is used in a narrow operating room and is moved close to the floor, the display of the rear display area 27 will be visible to the operator or clinical engineer. The lower end 26a of the front display area 26 may be in the same position in the vertical direction V as the lower end 27a of the rear display area 27. 【0031】 In addition to the installation range L3 of the gripping portion 12a in the vertical direction V being within the range of the length L1 of the front display area 26 and the range of the length L2 of the back display area 27, a portion of the installation range L3 of the gripping portion 12a may overlap with the range of the length L1 of the front display area 26 or the range of the length L2 of the back display area 27. For example, as shown in Figure 13, the installation range L3 of the gripping portion 12a is set within the range of the length L2 of the back display area 27, while a portion of the installation range L3 of the gripping portion 12a overlaps with a portion of the range of the length L1 of the front display area 26, and the rest is located below the front display area 26 outside the range of length L1. 【0032】As shown in Figure 14, the back surface 23 may be provided with a horizontal gripping portion 12b (second gripping portion) extending in the lateral direction H below the vertical direction V of the back surface display area 27. When moving the ultrasound diagnostic device 10, the transporter can grasp both the vertical gripping portion 12a and the horizontal gripping portion 12b with their hands, allowing the ultrasound diagnostic device 10 to be moved stably without using anything other than the transporter's hands, such as the transporter's chest. Furthermore, when the ultrasound diagnostic device 10 is moved with various devices such as a printer and a computing device placed on the base 28, if the back surface 23 is about to collide with a wall or the like, the horizontal gripping portion 12b will first collide with the wall or the like, and the gripping portion 12b will function like a car bumper, thus preventing the various devices placed on the base 28 from directly colliding with the wall or the like. 【0033】 As shown in Figure 15, it is preferable that the length D1 (depth) of the first region R1 in the normal direction N is smaller than the length D2 (depth) of the second region R2 in the normal direction N. Also, it is preferable that the length LR1 of the first region R1 in the vertical direction V is larger than the length LR2 of the second region R2 in the vertical direction V. In this case, the first region R1 includes the front portion 21, and the second region R2 includes the portion of the ultrasound diagnostic device 10 excluding the front portion 21, and corresponding to the portion below the front portion 21. 【0034】Furthermore, the length D1 is preferably the distance between the end of the caster mounting plate 28a of the base 28 and the flat portion 21a, and is preferably 120 mm or less. Furthermore, the length D2 is preferably the length in the normal direction N of the caster mounting plate 28a, and is preferably 180 mm or less. Furthermore, the shape of the caster mounting plate 28a is preferably close to a square, and therefore, the aspect ratio of the caster mounting plate 28a is preferably close to a square, ranging from 1.4:1 to 1:1. By defining the first region R1 or the second region R2 as described above, even when various devices such as printers and computing devices are placed on the base 28, the center of gravity of the ultrasound diagnostic device 10 is less likely to shift, and the ultrasound diagnostic device 10 can be stably installed or moved. Furthermore, by considering the weight ratio between the first and second regions, setting the length D1 to be less than or equal to the thickness of two liquid crystal monitors included in the front 21 and back 23 of the first region, and setting the length D2 to be about 1.5 times the thickness of the liquid crystal monitor, the center of gravity of the entire ultrasound diagnostic device 10 is stabilized. 【0035】 In this embodiment, the surface of the housing portion 11 and the surface of the back portion 23, including the back display area 27, are flat. For example, as shown in the cross-section of the back portion 23 in Figure 16, the surface of the back portion 23, including the back display area 27, is flat. Also, as shown in Figure 17, the side end portion 22 has a structure that is curved in a convex shape between the front portion 21 and the back portion 23, making it difficult for dirt and other debris to enter. As a result, the entire housing portion 11, including the back display area 27, is resistant to dirt and other debris, and even if blood or other substances generated during surgery adhere to it, it can be easily removed by wiping. Therefore, the burden of post-operative cleaning can be reduced, and as a result, cleanliness can be maintained with simple cleaning. It is preferable that the surface of the housing portion 11 and the back display area 27 be a flush structure with gaps and irregularities of 0.5 mm or less, and be made of a wipe-resistant material compliant with IEC 60601-1. 【0036】The front display area 26 and the back display area 27 may be separate. For example, as shown in Figure 4, the back monitor 30 having the back display area 27 may be detachably attached to the housing 11. On the other hand, as shown in Figure 5, it is preferable that the ultrasound diagnostic apparatus 10 includes a display panel 31 that includes a front display area 26 and a back display area 27. The display panel 31 is continuously provided from the front portion 21 through the upper end portion 32 of the housing 11 to the back portion 23. This allows the display panel 31 to display as much biological information as possible in both the front display area 26 and the back display area 27. The back monitor 30 may be fixed to the housing 11. In this case, it is preferable that no gaps or irregularities occur between the housing 11 and the monitor in order to improve cleanability and hygiene. 【0037】 As shown in Figures 6(A) and (B), the amount of information displayed in the rear display area 27 may be the same as the amount of information displayed in area 26b of the front display area 26 that corresponds to the installation area of the rear display area 27. By displaying the minimum necessary amount of biological information in area 26b, the minimum necessary amount of biological information can also be confirmed or manipulated in the rear display area 27. Furthermore, it is preferable that the width W2 of the rear display area 27 be less than or equal to the width W1 of the front display area 26. Note that "the amount of information is the same" includes not only cases where the amount of information is exactly the same, but also cases where there is a difference in the amount of information, but it can be considered to be approximately the same. 【0038】The rear display area 27 preferably displays content shown in at least a portion of the front display area 26. Specifically, the content displayed in at least a portion of it preferably is a GUI (Graphical User Interface). By arranging an operating system such as a GUI on the front display area 26 or rear display area 27 extending in the vertical direction V, and arranging the operating system and the display system on the same plane, observation of the display area 25 and various operations on the ultrasound diagnostic device 10 can be performed without burdening the user. On the other hand, in conventional ultrasound diagnostic devices, the device's control console was placed on a horizontal surface such as a cart, and the monitor was placed in the vertical direction. Therefore, in order to arrange both the control console and the monitor, it was necessary to offset them in the vertical direction V, or to place the control console on the main unit and the monitor at a distance from the main unit, thus separating their positions. As a result, it was difficult to place the monitor and the control console on the same plane, and the two actions of observation and operation were separated, which was burdensome for the user performing both. 【0039】 For example, as shown in Figures 7(A) and 7(B), the GUI 35 of the front display area 26 is positioned below the vertical direction V of the front display area 26 (preferably below the vertical direction V of area 26b (see Figure 6(A))). On the other hand, the GUI 36 of the back display area 27 is positioned above the vertical direction V of the back display area 27, or across the entire surface of the back display area 27. It is preferable that the GUI 35 of the front display area 26 displays GUIs that are not displayed in the GUI 36 of the back display area 27. Conversely, it is preferable that the GUI 36 of the back display area 27 displays GUIs that are not displayed in the GUI 35 of the front display area 26. 【0040】Furthermore, it is preferable that input to the GUI 35 of the front display area 26 takes precedence over input to the GUI 36 of the rear display area 27. In this case, as shown in Figures 8(A) and (B), if a touch operation T1 for the GUI 35 and a touch operation T2 for the GUI 36 are performed simultaneously within a certain period, touch operation T1 takes precedence over touch operation T2, enabling the input to the GUI 35 while disabling the input to the GUI 36. Conversely, input to the GUI 36 of the rear display area 27 may take precedence over input to the GUI 35 of the front display area 26. 【0041】 Furthermore, when the GUI 35 of the front display area 26 is operated, it is preferable to reflect the operation content in the GUI 36 of the rear display area 27. In this case, as shown in Figures 9(A) and (B), when a touch operation T1 is performed on the GUI 35, the GUI 36a of the rear display area 27 that corresponds to the GUI 35a on which the touch operation T1 was performed (and has the same function) is automatically operated in conjunction with the touch operation T1. Conversely, when the GUI 36 of the rear display area 27 is operated, the operation content may be reflected in the GUI 35 of the front display area 26. 【0042】 Furthermore, when the GUI 35 in the front display area 26 is operated, it is preferable that the operation result displayed in the front display area 26 is also displayed in the back display area 27. In this case, as shown in Figures 10(A) and (B), when a touch operation T1 is performed on the GUI 35, the operation result 38 obtained by the touch operation T1 is displayed on the front display area 26 and also on the back display area 27. At that time, it is preferable to also display an auxiliary indicator 39 indicating that the operation result 38 was obtained by a touch operation T1 on the GUI 35. Conversely, when the GUI 36 in the back display area 27 is operated, the operation result displayed in the back display area 27 may be displayed on the front display area 26. 【0043】In this embodiment, each process is executed by an arbitrary computer. Also, an arbitrary computer may execute these processes by a processor, a program, or a combination thereof. An arbitrary computer may be a general-purpose computer, a computer dedicated to a specific use, a system such as a workstation, or other hardware elements capable of executing a program. 【0044】 The processor may be constituted by one or more hardware, and the type of hardware is not limited. For example, the processor may be constituted by hardware such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a programmable logic device such as an FPGA (Field Programmable Gate Array), an application specific circuit for executing specific processes such as an ASIC (Application Specific Integrated Circuit), a GPU (Graphic Processing Unit), or an NPU (Neural Processing Unit). Also, the processor has each part (Unit) or each means for executing various processes in this embodiment. Also, the type of hardware may be a combination of different types of hardware. When a plurality of hardware are configured to execute one or more processes of a certain processor, the plurality of hardware may exist in physically separated devices from each other, or may exist in the same device. Also, in any embodiment, the order of each process by the processor is not limited to the order described above, and may be changed as appropriate. Note that the hardware is constituted by an electric circuit (circuitry) combining circuit elements such as semiconductor elements. 【0045】Furthermore, this embodiment may be implemented by hardware, software, firmware, microcode, or a combination thereof. The software, firmware, and microcode are composed of a program. The program may also be, for example, a group of program modules, each of which may be implemented by a processor configured to perform its respective function. The program may be program code or multiple code segments stored on one or more non-temporary computer-readable media (e.g., recording media or other storage). The program may be divided and stored on multiple non-temporary computer-readable media located on devices that are physically separated from each other. The program code or code segment may represent any combination of procedures, functions, subprograms, routines, subroutines, modules, software packages, classes, or instructions, data structures, or program statements. The program code or code segment may be connected to other code segments or hardware circuits by sending and receiving information, data, arguments, parameters, or memory contents. 【0046】 10 Ultrasound diagnostic device 11 Housing 12 Handle 12a Gripping part 12b Gripping part 13 Caster 21 Front view 23 Rear view 24 Contact element holding part 25 Display area 26 Front display area 26a Lower end 26b Area 27 Rear display area 27a Lower end 28 Base 28a Caster mounting plate 30 Rear monitor 31 Display panel 32 Upper end 35, 36 GUI 38 Operation result 39 Auxiliary display V Vertical direction N Normal direction L1, L2 Length L3 Installation range W1, W2, W3 Width T1, T2 Touch operation R1 First area R2 Second area R3 Third area
