Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a control button, control box and medical device. Background Technology

[0002] In the use of medical imaging equipment such as computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI), due to radiation and strong magnetic fields, operators need to perform operations such as bed control, exposure initiation / stop, etc., in an operating room outside the scanning / shielding room. They also need to communicate with patients to provide necessary guidance and reassurance. Therefore, a control box is usually installed in the operating room as a medium for human-computer interaction.

[0003] Based on safety requirements and the need for blind operation in some scenarios, it is still necessary to retain physical control buttons on the control box to a certain extent. However, too many control buttons make the interface cluttered and unattractive, and make it difficult to identify and operate. In addition, in today's era of significant development in multimedia technology, they appear outdated and monotonous. Therefore, more functions are integrated into the control buttons.

[0004] In related technologies, the corresponding control switch is usually triggered by pressing the pressing part of the control button. However, when the control button is large, there are cases where the control switch cannot be triggered when pressing some parts of the control button. Utility Model Content

The control switch is used for communicative connection with the actuator. Pressing any position of the button assembly can cause the button assembly to drive the support portion to move, and cause the control portion to trigger the control switch.

[0018] Thirdly, embodiments of this application provide a medical device, which includes an actuator and a control box as described in the second aspect.

[0019] The control button provided in this application has the following advantages: Since the control button includes a button assembly, a moving part, and a fixing part arranged in sequence, the moving part includes a bearing part and an elastic part, and a control part is provided on the side of the bearing part away from the button assembly, the elastic part is located between the bearing part and the fixing part, and the control part and the elastic part are spaced apart, pressing any part of the button assembly can compress the elastic part and cause the button assembly to drive the bearing part to move, thereby enabling the control part to trigger the control switch on the fixing part to achieve the purpose of controlling the actuator of the medical device.

[0044] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0045] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0047] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0048] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0049] In the use of medical imaging equipment such as computed tomography (CT), positron emission tomography (PET), and magnetic resonance imaging (MRI), due to radiation and strong magnetic fields, operators need to perform operations such as bed control, exposure initiation / stop, etc., in an operating room outside the scanning / shielding room. They also need to communicate with patients to provide necessary guidance and reassurance. Therefore, a control box is typically installed in the operating room as a medium for human-computer interaction.

[0050] Based on safety requirements and the need for blind operation in some scenarios, it is still necessary to retain physical control buttons on the control box to a certain extent. However, too many control buttons make the interface cluttered and unattractive, and make it difficult to identify and operate. In addition, in today's era of significant development in multimedia technology, they appear outdated and monotonous. Therefore, more functions are integrated into the control buttons.

[0051] In related technologies, in order to improve the interactive experience of control buttons and ensure the interactive effect, it is necessary to set up a display screen on the control buttons and set up a motor to drive the control knob to rotate.

[0052] In some types of control buttons, the corresponding control switch is usually triggered by pressing the pressing part of the control button. However, when the control button is large, there may be situations where the control switch cannot be triggered when pressing certain parts of the control button.

[0053] In view of this, this application provides a control button, a control box, and a medical device. The control button includes a button assembly, a moving part, and a fixing part arranged in sequence. The moving part includes a support part and an elastic part. A control part is provided on the side of the support part away from the button assembly. The elastic part is located between the support part and the fixing part. The control part and the elastic part are spaced apart. Therefore, pressing any part of the button assembly can compress the elastic part and cause the button assembly to drive the support part to move. This allows the control part to trigger the control switch on the fixing part, thereby achieving the purpose of controlling the actuator of the medical device.

[0054] Please refer to Figures 1 to 5 In one aspect, embodiments of this application provide a control button 100 for a medical device, the medical device including an actuator.

[0055] Medical devices can be medical imaging equipment such as CT, PET, and MRI, or other equipment. Actuating elements can include motors, cylinders, or solenoid valves. These actuating elements are used to drive the movement of devices such as hospital beds, robotic arms, or lifting platforms.

[0056] Please refer to this as well. Figures 6 to 9 The control button 100 includes a button assembly 10, a moving part 20, and a fixing part 30 arranged sequentially. For example, the button assembly 10, the moving part 20, and the fixing part 30 are arranged sequentially along a first direction, which may be the direction indicated by arrow M in the figure.

[0057] The movable part 20 includes a support part 21 and an elastic part 22. The support part 21 is provided with a control part 23 on the side opposite to the button assembly 10. The elastic part 22 is located between the support part 21 and the fixing part 30, and the control part 23 and the elastic part 22 are spaced apart.

[0058] The elastic part 22 can be a spring, an elastic pin, elastic rubber, or elastic silicone, etc. One or more elastic parts 22 can be provided. The control part 23 can be a portion of the support part 21, or the control part 23 can be a protrusion, etc.

[0059] A control switch 31 is provided on the fixing member 30. The control switch 31 is used to communicate with the actuator (such as through a cable connection or a wireless network connection). Pressing any position of the button assembly 10 (such as pressing any position of the button assembly 10 in the first direction) can cause the button assembly 10 to drive the carrier 21 to move (such as moving in the first direction), and cause the control unit 23 to trigger the control switch 31.

[0060] The control switch 31 can be a micro switch or other switches. For example, the fixing member 30 is a main board, the control switch 31 is a micro switch mounted on the main board, the micro switch is communicatively connected to the control switch 31, and the main board is communicatively connected to the actuator.

[0061] Since the elastic part 22 is located between the support part 21 and the fixing member 30, when the button assembly 10 is not pressed in the first direction, the elastic part can abut against the fixing member 30 to prevent the support part 21 of the control part 23 from moving in the first direction, thus preventing the control part 23 from triggering the control switch 31. When any part of the button assembly 10 is pressed in the first direction, the elastic part 22 is compressed, causing the button assembly 10 to drive the support part 21 to move in the first direction, and the control part 23 triggers the control switch 31.

[0062] As can be seen from the above, the control button 100 provided in this application embodiment includes a button assembly 10, a moving part 20, and a fixing part 30 arranged sequentially. The moving part 20 includes a supporting part 21 and an elastic part 22. A control part 23 is provided on the side of the supporting part 21 away from the button assembly 10. The elastic part 22 is located between the supporting part 21 and the fixing part 30. The control part 23 and the elastic part 22 are spaced apart. Therefore, pressing any part of the button assembly 10 can compress the elastic part 22 and drive the supporting part 21 to move, thereby enabling the control part 23 to trigger the control switch 31 on the fixing part 30 to achieve the purpose of controlling the actuator of the medical device.

[0063] Please refer to Figures 6 to 9 In some embodiments, the button assembly 10 includes a display screen 11 located on the side of the movable member 20 away from the fixed member 30, and the display screen 11 is disposed facing away from the movable member 20.

[0064] By adopting the above solution, a display function can be integrated into the control button 100, thereby enriching the functions of the control button 100.

[0065] Understandably, the control knob with display screen 11 can be widely used in various human-computer interaction scenarios. On the one hand, it retains the touch operation feel of a physical knob, and on the other hand, it realizes a wide variety of functions and advanced interactive fun through the UI (User Interface) on the display screen 11.

[0066] It should be noted that the display screen 11 is oriented towards the second direction, which is opposite to the first direction. The second direction can be the direction indicated by arrow N in the figure. When the button assembly 10 is pressed along the first direction, the display screen 11 or other parts of the button assembly 10 can be pressed.

[0067] It should also be noted that since the button assembly 10 includes a display screen 11, in order to ensure the interactive effect, the display screen 11 needs to have a certain area and is set to be relatively large. Therefore, the area of ​​the corresponding part of the button assembly 10 is relatively large. In this application, pressing any part of the button assembly 10 along the first direction can compress the elastic part 22 and cause the button assembly 10 to drive the bearing part 21 to move along the first direction, thereby enabling the control part 23 to trigger the control switch 31 on the fixing member 30 to achieve the purpose of controlling the actuator of the medical device.

[0068] For example, the display screen 11 includes an adapter plate and a circular LCD (Liquid Crystal Display) screen, which are bonded together with double-sided adhesive.

[0069] Optionally, the button assembly 10 also includes a transparent cover 12, with the display screen 11 located between the transparent cover 12 and the movable element 20.

[0070] This design allows the transparent cover 12 to protect the display screen 11 and prevent damage to it.

[0071] It is understood that when the button assembly 10 is pressed in the first direction, the transparent cover 12 or other parts of the button assembly 10 can be pressed.

[0072] For example, the transparent cover 12 can be made of transparent glass or transparent plastic, etc.

[0073] Please refer to Figures 6 to 9 In some embodiments, the button assembly 10 further includes a movable housing 13, the display screen 11 is disposed inside the movable housing 13, and the movable housing 13 is rotatable relative to the support portion 21; a detection sensor 32 is provided on the fixing member 30, and the detection sensor 32 is used to obtain the angle of rotation of the movable housing 13 relative to the support portion 21.

[0074] By adopting the above solution, the control switch 31 can be triggered by pressing the button assembly 10 in the first direction, and the moving housing 13 can be rotated relative to the support part 21. The angle of rotation of the moving housing 13 relative to the support part 21 can be obtained by the detection sensor 32, thereby enriching the functions of the button assembly 10.

[0075] It is understood that pressing the button assembly 10 in the first direction can press the movable housing 13 or other parts of the button assembly 10. The detection sensor 32 may include a grating or a ring contact sensor, etc.

[0076] For example, when the detection sensor 32 includes a grating, the "angular displacement" of the moving housing 13 is converted into a "countable electrical pulse signal" by combining the grating with photoelectric elements, and then the actual rotation angle is obtained by counting the pulses and converting them into angles.

[0077] When the detection sensor 32 includes a ring contact sensor, the ring contact sensor is in continuous contact with the conductive component on the moving housing 13 through its ring contact. When the moving housing 13 rotates, the contact position between the contact and the conductive component changes, thereby changing the resistance or voltage signal inside the ring contact sensor. The rotation angle of the moving housing 13 is reflected by detecting the change in this signal.

[0078] For example, the transparent cover 12 is connected to the movable housing 13. When the button assembly 10 is pressed in the first direction, the transparent cover 12 and the movable housing 13 can be pressed, and the display screen 11, the transparent cover 12, the movable housing 13, and the moving member 20 can move together in the first direction. Alternatively, the transparent cover 12, the movable housing 13, and the moving member 20 can move together in the first direction, while the display screen 11 remains stationary.

[0079] The button assembly 10 also includes a drive motor 14, which includes a stator 141 and a rotor 142. The rotor 142 is used to connect with the moving housing 13, and the stator 141 is used to connect with the support part 21.

[0080] By adopting the above scheme, when the moving housing 13 rotates relative to the bearing part 21, the stator 141 and the rotor 142 cooperate to apply damping to the moving housing 13, thereby providing different feedback in different control function scenarios.

[0081] To provide different tactile feedback for different operations and thus enhance the interactive experience, the drive motor 14 can optionally be a programmable motor. For example, three different feedback modes can be programmed: the first is a damping mode, providing a small, constant torque opposite to the rotation direction of the moving housing 13 (based on the initial state); the second is a torsion spring mode, providing a varying torque opposite to the rotation direction of the moving housing 13, with the magnitude proportional to the amount of torsion; the third is an escapement mode, where the circumference is divided into 12 divisions, and when the moving housing 13 is torn, the brushless motor provides a torque pointing to the nearest division position, the magnitude of which is proportional to the distance relative to this division, and the torque reaches its maximum in the middle of two divisions and undergoes a change in direction.

[0082] This setup allows for different control operations to be matched with different modes of the programmed motor, providing different tactile feedback for different operations and thus enhancing the interactive experience.

[0083] Optionally, the button assembly 10 further includes a first connector 15, which includes a main body 151 and a connecting shaft 152 connected to each other. The main body 151 is located between the drive motor 14 and the support part 21. The stator 141 is connected to the main body 151. At least a portion of the main body 151 abuts against the support part 21 (e.g., abuts against the support part 21 in a first direction). The connecting shaft 152 passes through the stator 141 and the rotor 142 in sequence (e.g., passes through the stator 141 and the rotor 142 in a second direction in sequence), and one end of the connecting shaft 152 away from the connecting shaft 152 is connected to the display screen 11.

[0084] With this configuration, the display screen 11 and the support unit 21 can be connected via the first connector 15, and the stator 141 of the motor can be easily fixed.

[0085] It should be noted that the connecting shaft 152 can be hollow. The stator 141 and rotor 142 are hollow at the corresponding parts of the connecting shaft 152.

[0086] Optionally, the button assembly 10 further includes an annular magnet 16 and a gasket 161. The annular magnet 16 is sleeved on the connecting shaft 152, and the gasket 161 is located between the stator 141 and the main body 151. The annular magnet 16 is located between the main body 151 and the gasket 161. The detection sensor 32 is a magnetic encoding sensor, which is coaxially arranged with the annular magnet 16.

[0087] With this configuration, the metal motor shaft of the drive motor 14 can be prevented from interfering with the magnetic field of the annular magnet 16 by the shim 161, thereby affecting the detection of the magnetic coding sensor.

[0088] It should be noted that the material of the gasket 161 can be plastic or a non-magnetic metal. The annular magnet 16 is radially magnetized. The magnetic encoder sensor determines the rotation angle by detecting the deflection of the magnetic field direction.

[0089] The button assembly 10 also includes a second connector 17 and a third connector 18. The end of the connecting shaft 152 away from the connecting shaft 152 is connected to the display screen 11 through the second connector 17, and the moving housing 13 is connected to the rotor 142 through the third connector 18.

[0090] For example, the moving housing 13 is fixed to the third connector 18 by a snap-fit ​​and insert structure, and the third connector 18 is fixed to the screw hole of the rotor 142 by screws. The first connector 15 is fixed to the end of the connecting shaft 152 away from the connecting shaft 152 by a snap-fit ​​and insert structure, and the display screen 11 is fixed to the snap-fit ​​structure by the limiting post on the first connector 15.

[0091] Please refer to Figures 6 to 9In some embodiments, the control button 100 further includes a fixed housing 40, which is provided with a clearance hole. The main body 151 is provided with a boss 1511 and a retaining part 1512. The boss 1511 passes through the clearance hole and abuts against the bearing part 21 (e.g., passes through the clearance hole and abuts against the bearing part 21 in a first direction), and the retaining part 1512 is retained in the fixed housing 40 (e.g., retained in the fixed housing 40 in a second direction).

[0092] By adopting the above solution, the relative position of the first connector 15 and the fixed housing 40 can be fixed (in a direction parallel to the first direction), and the rotation of the first connector 15 relative to the fixed housing 40 can be avoided.

[0093] It is understandable that one or more of the boss 1511 and the retaining part 1512 may be provided.

[0094] Optionally, the fixed housing 40 is provided with a mating part 41, and the moving part 20 is provided with a stop part 211. The mating part 41 and the stop part 211 cooperate to restrict the rotation of the bearing part 21 relative to the fixed housing 40.

[0095] With this configuration, the mounting portion 41 can cooperate with the stop portion 211 to restrict the rotation of the bearing portion 21 relative to the fixed housing 40.

[0096] For example, one of the mating part 41 and the stop part 211 may be configured as a protrusion, and the other of the mating part 41 and the stop part 211 may be configured as a recess. One or more mating parts 41 and stop parts 211 may be provided.

[0097] Optionally, there may be multiple elastic parts 22, and the control part 23 and any two elastic parts 22 may be arranged non-collinearly.

[0098] With this configuration, pressing any part of the button assembly 10 will compress the elastic part 22 and cause the button assembly 10 to drive the bearing part 21 to move, thereby enabling the control part 23 to trigger the control switch 31 on the fixing member 30 to control the actuator of the medical device.

[0099] It should be noted that the control unit 23 and any two elastic units 22 are arranged non-collinearly, that is, the line connecting the control unit 23 and one of the elastic units 22 is not collinear with the line connecting the control unit 23 and any other elastic unit 22.

[0100] For example, two elastic parts 22 are provided, and the line connecting the control part 23 and one of the elastic parts 22 is set at an angle to the line connecting the control part 23 and the other elastic part 22. That is, the line connecting the control part 23 and one of the elastic parts 22 is not collinear with the line connecting the control part 23 and the other elastic part 22. The control part 23 and the two elastic parts 22 can be distributed in a "triangle".

[0101] By adopting the above solution, it is possible to avoid having more than two elastic parts 22. When the button assembly 10 is pressed in the first direction, the control part 23 will be suspended due to multiple elastic parts 22 abutting against the fixing member 30, thus preventing the control switch 31 from being triggered.

[0102] Secondly, embodiments of this application provide a control box 1000, which includes control buttons 100 as described in the first aspect.

[0103] The control box 1000 provided in this application embodiment includes a control button 100 comprising a button assembly 10, a moving part 20, and a fixing part 30 arranged sequentially. The moving part 20 includes a support part 21 and an elastic part 22. A control part 23 is provided on the side of the support part 21 away from the button assembly 10. The elastic part 22 is located between the support part 21 and the fixing part 30. The control part 23 and the elastic part 22 are spaced apart. Therefore, pressing any part of the button assembly 10 can compress the elastic part 22 and cause the button assembly 10 to drive the support part 21 to move. This allows the control part 23 to trigger the control switch 31 on the fixing part 30, thereby achieving the purpose of controlling the actuator of the medical device.

[0104] The control box 1000 provided in this application embodiment can combine the control button 100 with the display screen 11 with the operation room control box 1000 of the medical imaging equipment. On the one hand, it reduces the number of physical buttons, and combined with the multimedia content prompts on the display screen 11, it makes human-computer interaction simpler, smoother and more intuitive. On the other hand, it retains the tactile feel of physical buttons and provides a variety of interactive feedback modes through the programmable drive motor 14, providing a certain interactive fun.

[0105] The device includes multiple actuators. The control switch 31 is used to communicate with some of the actuators. The control box 1000 is also equipped with a control button 200, which is used to communicate with another part of the actuators.

[0106] By adopting the above solution, control buttons 200 can be integrated into the control box 1000 to achieve more functions.

[0107] Optionally, the control box 1000 is also equipped with indicator lights 300.

[0108] For example, multiple control buttons 200 can be configured. For instance, when the medical equipment includes a hospital bed with multiple actuators, the control buttons 200 include five standard buttons (physical buttons) on the left and one emergency stop button and an exposure indicator light 300 on the right. The five standard buttons correspond to bed entry / exit, bed lifting, bed rotation, one-button bed retraction, and intercom function, respectively. A sound / radio hole is developed on the housing of the control box 1000.

[0109] The aforementioned control box 1000 has functions such as bed control, exposure control, and intercom. Bed control includes functions such as bed entry, bed exit, bed raising, bed lowering, clockwise bed rotation, counterclockwise bed rotation, bed movement (moving the bed according to a preset range during scanning after triggering), and one-button bed exit (the bed obtains a default position after triggering). Exposure control-related functions include exposure and pause. Intercom functions include intercom and receive / send functions, as well as volume adjustment.

[0110] By combining the control buttons 100 on the display screen 11 with the control box 1000 in the medical imaging equipment operating room, different interaction modes and operation methods are designed based on different control functions (entering / exiting the bed, intercom, volume adjustment, exposure control, etc.). The control buttons 100 are equipped with a non-touch display screen 11, and interaction and selection functions are achieved through physical rotation and pressing. The rotation counting function is achieved by a programmable drive motor 14 and a magnetic encoder sensor, while the pressing function is achieved by a micro switch.

[0111] The control box 1000 described above has the following interaction modes:

[0112] 1. Functional interaction modes for bed entry, bed exit, bed raising, bed lowering, clockwise bed rotation, and counterclockwise bed rotation.

[0113] There are two interaction modes when performing operations such as entering the bed, exiting the bed, raising the bed, lowering the bed, rotating the bed clockwise, and rotating the bed counterclockwise. Taking the entry and exit operation as an example.

[0114] Interaction Method 1 involves first clicking the bed entry / exit button, then rotating the moving housing 13. Rotating counter-clockwise retracts the bed, while rotating clockwise advances it. At this time, the drive motor 14 operates in torsion spring mode; the greater the rotation, the greater the feedback force, with a limit of 90° counter-clockwise / clockwise rotation. The amount of torsion corresponds to the bed's movement speed; the greater the torsion, the faster the bed moves. Releasing the knob resets the knob, and pressing and holding for 2 seconds returns the display screen 11 to the default interface. During bed entry / exit, the display screen 11 shows key information and animations related to the bed's movement. Interaction Method 2 involves pressing and holding the bed entry / exit button while simultaneously rotating the moving housing 13. The drive motor 14 operates in the same way as in Interaction Method 1.

[0115] 2. One-click bed exit function interaction mode.

[0116] The one-click bed-out function can be activated by simply clicking the bed-out button.

[0117] 3. Interactive modes for intercom and volume adjustment.

[0118] Press and hold the intercom button to communicate in real time with the scanning room. Quickly double-click the intercom button to enter the volume adjustment mode. The default is to enter the transmit volume adjustment mode. Clicking the moving housing 13 switches to the receive volume adjustment mode. The amount of twisting corresponds to the volume level; turning left decreases the volume, and turning right increases the volume. Adjustments beyond the volume range are ineffective. The drive motor 14 operates in damping mode. The display screen 11 shows the adjustment mode (transmit or receive) and the volume value. After releasing the button, the moving housing 13 stays in place (a slight shift is possible). Press and hold for 2 seconds to return the display screen 11 to the default interface.

[0119] Click the intercom button to enter the preset voice broadcast mode. The display screen 11 shows the voice to be broadcast and an animation prompt. Rotate left / right to switch to the previous / next voice. When switching voices, the drive motor 14 operates in escapement mode. Click the display screen 11 to send the corresponding preset voice. Press and hold the display screen 11 for 2 seconds to return to the default interface.

[0120] 4. Display screen 11 default interface.

[0121] The default interface of display screen 11 has the following sub-interfaces: exposure, bed movement, and the aforementioned functions: bed entry / exit, bed lifting, bed rotation, intercom, volume adjustment, etc. In the initial state and after returning from any interface, the default interface displays the exposure sub-interface. The rotating housing 13 can switch between different sub-interfaces. The drive motor 14 operates in escapement mode, which can be selected by clicking.

[0122] 5. Exposure control.

[0123] Exposure control can be accessed from the default interface. Clicking on the moving housing 13 will bring up a confirmation screen. Clicking on the moving housing 13 again will start the exposure. After exposure starts, clicking on the moving housing 13 will pause the exposure. All other buttons except the emergency stop button will be ineffective. After pausing, press and hold for 2 seconds to return to the default interface.

[0124] Thirdly, embodiments of this application provide a medical device, which includes an actuator and a control box 1000 as described in the second aspect.

[0125] The medical device provided in this application embodiment has a control box 1000 whose control button 100 includes a button assembly 10, a moving part 20, and a fixing part 30 arranged sequentially. The moving part 20 includes a supporting part 21 and an elastic part 22. The supporting part 21 is provided with a control part 23 on the side away from the button assembly 10. The elastic part 22 is located between the supporting part 21 and the fixing part 30. The control part 23 and the elastic part 22 are spaced apart. Therefore, pressing any part of the button assembly 10 can compress the elastic part 22 and cause the button assembly 10 to drive the supporting part 21 to move. This allows the control part 23 to trigger the control switch 31 on the fixing part 30, thereby achieving the purpose of controlling the actuator of the medical device.

[0126] It is understood that the medical equipment provided in the embodiments of this application may also include a hospital bed, a robotic arm or other functional components, which will not be described in detail here.
