DETAILED DESCRIPTION

[0053] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0054] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0055] With the development of society and the advancement of science and technology, medical equipment has been continuously updated and iterated, which has promoted the rapid development of the medical industry. Especially in the fields of CT scanning and radiotherapy, the improvement of equipment technology has not only improved the accuracy and efficiency of treatment, but also greatly improved the patient's treatment experience. However, in the use of medical equipment, patient safety is always a vital concern. How to effectively ensure patient safety while improving the convenience and accuracy of doctors' operations is an important topic in medical equipment design.

[0056] In modern medicine, the movement control system of the bed 20 plays a very important role. Especially in the treatment process such as CT scanning and radiotherapy, doctors often need to control the forward and backward operation of the bed 20 through the foot pedal. The design of the foot pedal was originally intended to facilitate doctors to free their hands and control the movement of the bed 20 by their feet when performing other operations. However, this design also brings some potential safety hazards, especially in the process of carrying and positioning the bed 20, the foot pedal may be accidentally stepped on, causing the bed 20 to move unexpectedly at an inappropriate time, thereby causing unnecessary accidents.

[0057] Although the existing symmetrical foot pedal design allows the doctor to control the bed 20 from either side of the bed 20 during operation, it also brings about a greater safety hazard. Since the foot pedal is located between the bed 20 and the frame, the doctor or the caregiver may easily step on the button on the foot pedal by mistake when carrying the patient, causing the bed 20 to move unexpectedly. For example, when the caregiver or the family member is carrying the patient, they may not be aware of the existence of the foot pedal, or accidentally step on the button for entering or exiting the bed during operation. Such an accidental stepping may cause the bed 20 to move suddenly, increasing the risk to the patient and may even lead to a medical accident.

[0058] In order to avoid accidentally stepping on the pedal, doctors usually need to give extra reminders to caregivers or family members when they are carrying patients, reminding them to be careful with the pedal and avoid accidentally stepping on it. Although this small move can reduce the probability of misoperation to a certain extent, it also invisibly increases the workload of doctors, especially in a busy medical environment, where doctors have to be distracted to ensure the safety of other personnel's operations. Although this approach can play a certain preventive role, it cannot completely eliminate the risk of accidentally stepping on the pedal, and there are still potential safety hazards.

[0059] To solve the above technical problems, Figure 1 , 2 As shown, one embodiment of the present invention provides a medical device, including a working unit 10, a bed 20, a mobile unit and a controller 30. The medical device can be a CT scanner (computed tomography scanner), a magnetic resonance imaging device (MR), a radiotherapy machine and other devices with a bed 20.

[0060] The working unit 10 is used to perform medical-related actions. The working unit 10 completes specific diagnosis and treatment tasks during the medical process. For example, in the diagnosis and treatment processes such as CT scanning, radiotherapy, and magnetic resonance imaging, the working unit 10 refers to the relevant scanner or treatment equipment. The main task of this unit is to perform medical operations.

[0061] The bed 20 is movably arranged to enter or exit the working area of ​​the working unit 10. The bed 20 is the part where the patient is located, and it enters or exits the working area of ​​the working unit 10 by moving to ensure that the patient can be accurately positioned on the working unit 10.

[0062] The moving unit is used to drive the bed 20 to enter or exit the working area of ​​the working unit 10 along a first direction. The first direction is defined as the length direction of the bed. The moving unit is responsible for driving the bed 20 to move along the length direction of the bed, so that the bed 20 enters or exits the working area of ​​the working unit 10. This unit can be composed of an electric motor, a slide rail system, a transmission mechanism, etc., to ensure the smooth and precise movement of the bed.

[0063] The controller 30 is used to control the movement of the moving unit. Through the controller 30, the user can control the bed to move precisely along a set direction.

[0064] The controller 30 is used for the user to control the movement of the mobile unit by foot pedaling. The purpose of foot pedaling is to free the user's hands so that the user can perform other operations at the same time (such as operating other equipment, adjusting the patient's position, etc.). Through the foot pedal trigger, the doctor or other operator can move the bed conveniently.

[0065] The controller 30 is configured to be operated only from one side of the bed 20. In order to avoid accidents caused by stepping on it by mistake, the design of the controller 30 particularly emphasizes that it can only be operated from one side of the bed 20. This one-side operation mode greatly reduces the risk of misoperation, especially when the caregiver or family member moves the patient, it can avoid unnecessary movement of the bed and ensure the safety of the patient.

[0066] like Figure 1 , 3 As shown, the controller 30 may include one or more trigger parts 31 for users to step on. If multiple trigger parts 31 are designed, other trigger parts 31 can be disabled by software or physical means, and only one trigger part 31 is retained. In this way, the operation is limited to only being able to be operated from one side of the bed body 20, further avoiding the occurrence of misoperation. For example, a doctor or operator only needs to use the foot control button on one side to move the bed, and will not accidentally step on the button on the other side, resulting in unnecessary movement of the bed.

[0067] In the medical device of Example 1, the controller 30 only includes a trigger part 31 for the user to step on, and the trigger part 31 is specifically a foot pedal for the user to step on. The board surface of the foot pedal faces one side of the bed 20, and the foot pedal is arranged as a whole at an angle, and the board surface of the foot pedal faces obliquely upward for easy stepping. This means that when the operator stands next to the bed 20, he can easily touch the pedal with his feet to operate. This design detail improves the operator's operating convenience, especially when the bed 20 moves, the operator does not need to turn around or stretch out his hand, and can directly control it with his feet. The trigger part 31 is in a normally open enabled state. This means that under normal circumstances, the trigger part 31 is always in the "on" state, and the bed 20 can start to move as needed.

[0068] The prior art usually has two sets of pedals, but the present application only retains one set of pedals, and simplifies the internal design by removing the other set of pedals. The traditional two-set pedal system will increase the design complexity, especially in terms of the wiring inside the key, the control circuit, etc. This design only retains one set of pedals, making the structure simpler, reducing the production and maintenance costs, and at the same time not affecting the operation.

[0069] The trigger part 31 can be stepped on on both sides, and both sides of the trigger part 31 can be stepped on. That is, no matter whether the same foot pedal is installed on the left or right side of the bed 20, the operator can step on the corresponding side of the bed 20 to control the movement of the bed 20. In this way, there is no need to design different trigger parts 31 for the positions on both sides of the bed 20, and the trigger part 31 can be directly set on the left or right side of the bed 20 as needed.

[0070] like Figure 2 , 4 As shown, the trigger unit 31 of the medical device of the first embodiment includes two buttons, and the two buttons respectively control the moving direction of the bed 20.

[0071] Specifically, the buttons include:

[0072] The first button 33 controls the bed 20 to move toward the working unit 10 , that is, to make the bed 20 approach the working unit 10 .

[0073] The second button 34 controls the bed 20 to move away from the working unit 10 , that is, the bed 20 moves in a direction away from the working unit 10 .

[0074] An indicator light 32 is set for each button. When the button is pressed or enabled in a specific mode, the indicator light 32 lights up (such as always on or flashing), indicating that the button is working and the bed 20 is moving according to the control signal. When the button is not pressed, the indicator light 32 is off or displayed in a different color (for example, red means unavailable, or the indicator light 32 is not on). This ensures that the operator will not mistakenly think that a button is in an enabled state. The indicator light 32 can reflect the state of movement of the bed 20 in real time, so that the operator can clearly know in which direction the bed 20 is currently moving to avoid misoperation. For example, when the operator presses the first button 33, the relevant indicator light 32 lights up, and the bed 20 begins to approach the working unit 10; if the second button 34 is pressed, the indicator light 32 lights up, and the bed 20 moves away from the working unit 10.

[0075] like Figure 7-9 As shown, in the medical device of the first embodiment, each of the trigger parts 31 is correspondingly provided with a shielding part 35, and the shielding part 35 shields the top of the trigger part 31. The shielding part 35 shields the top of the trigger part 31 to prevent other objects or unexpected actions in the environment from interfering with the operation of the trigger part 31. The shielding part 35 is assembled to avoid the user's feet horizontally, so as to allow the user's feet to extend horizontally into the trigger part 31 to perform the foot-stepping action. In particular, it prevents the user from accidentally stepping on the trigger part 31 from other positions or incorrect angles. The shielding part 35 protects the trigger part 31 from unnecessary interference or improper use through a certain physical structure, while ensuring that the user can conveniently control it by foot during normal operation.

[0076] like Figure 3 As shown, in the medical device of the first embodiment, the controller 30 is arranged between the bed 20 and the working unit 10. Since there is a certain physical distance between the bed 20 and the working unit 10, an obstacle area is usually formed, and the operator and the staff will try to avoid entering this area when using it. The position setting of the controller 30 makes the staff usually consciously enter the area and step on the controller 30 when operating. The setting of this position relatively avoids unintentional operation. The existence of this interval reduces the contact between the staff and the controller 30. Compared with placing the controller 30 at other positions of the bed 20 or the working unit 10, such a design can effectively prevent accidental touches.

[0077] The present invention also provides a medical device control method, which is applied to medical devices, such as Figure 1-9 As shown, it is applied to the medical device of the second embodiment.

[0078] The medical device of the second embodiment includes a working unit 10, a bed 20, a moving unit and a controller 30. The working unit 10 is used to perform medical-related actions, and the controller 30 is used to control the moving unit through user operation to move the bed 20. The controller 30 is designed as a foot-operated trigger part 31, and the user controls the movement of the bed 20 by foot-operating.

[0079] The controller 30 includes at least two triggering parts 31 for users to step on, and each triggering part 31 is used to control the movement of the bed body 20. The triggering part 31 is usually designed as a pedal. When the operator steps on it, the triggering part 31 will send a signal to control the moving unit, so that the bed body 20 is adjusted in a predetermined direction or position.

[0080] Specifically, two trigger parts 31 are symmetrically arranged to be consistent with the trigger parts 31 in the prior art, that is, the trigger parts 31 can be installed on the left and right sides of the bed 20, so that the operator can choose one side to operate according to his or her standing position.

[0081] The two trigger parts 31 can disable one of the trigger parts 31 through software control, so that only one trigger part 31 is effective, so that the device is only allowed to be operated from one side of the bed 20. In this way, there is no need to change the hardware structure. Since the trigger part 31 is still designed in a symmetrical manner and the hardware part remains unchanged, there is no need to physically change the device. It is only necessary to disable one trigger part 31 through software push to enable the user to operate from one side of the bed 20. Through the flexible configuration of the software, the device can adjust the operation mode in different situations (such as changes in operating requirements, special requirements of the medical environment, etc.). For example, in some cases, the operator may only be required to operate from one side of the bed 20, and disabling the trigger part 31 on the other side can meet this requirement.

[0082] like Figure 1 , 3 As shown, the controller 30 is arranged between the bed 20 and the working unit 10. Since there is a certain physical distance between the bed 20 and the working unit 10, an obstacle area is usually formed, and the operator and the staff will try to avoid entering this area when using it. The position setting of the controller 30 requires the staff to consciously enter this area and step on the controller 30 when operating. The setting of this position relatively avoids unintentional operation. The existence of this interval reduces the contact between the staff and the controller 30. Compared with placing the controller 30 at other positions of the bed 20 or the working unit 10, this design can effectively prevent accidental touches.

[0083] like Figure 2 , 4As shown, an indicator light 32 is correspondingly provided on each of the triggering parts 31. The function of the indicator light 32 is to display whether the triggering part 31 is enabled. The state of the indicator light 32 can intuitively inform the operator which triggering parts 31 are currently valid, thereby avoiding misoperation. When the triggering part 31 is enabled, the corresponding indicator light 32 lights up and indicates in some way (such as green, flashing, etc.) that the triggering part 31 is working effectively. When the triggering part 31 is disabled, the indicator light 32 can be displayed in different states (for example, red, off, etc.), clearly informing the operator that the triggering part 31 is currently unavailable.

[0084] like Figure 2 , 4 As shown, the trigger unit 31 includes two buttons, and the two buttons respectively control the moving direction of the bed body 20.

[0085] Specifically, the buttons include:

[0086] The first button 33 controls the bed 20 to move toward the working unit 10 , that is, to make the bed 20 approach the working unit 10 .

[0087] The second button 34 controls the bed 20 to move away from the working unit 10 , that is, the bed 20 moves in a direction away from the working unit 10 .

[0088] An indicator light 32 is set for each button. When the button is pressed or enabled in a specific mode, the indicator light 32 lights up (such as always on or flashing), indicating that the button is working and the bed 20 is moving according to the control signal. When the button is not pressed, the indicator light 32 is off or displayed in a different color (for example, red means unavailable, or the indicator light 32 is not on). This ensures that the operator will not mistakenly think that a button is in an enabled state. The indicator light 32 can reflect the state of movement of the bed 20 in real time, so that the operator can clearly know in which direction the bed 20 is currently moving to avoid misoperation. For example, when the operator presses the first button 33, the relevant indicator light 32 lights up, and the bed 20 begins to approach the working unit 10; if the second button 34 is pressed, the indicator light 32 lights up, and the bed 20 moves away from the working unit 10.

[0089] like Figure 5 As shown, the first button 33 is installed on one side of the trigger part 31, and a wiring harness connection position 36 can be set at a position of the trigger part 31 away from the first button 33, and the wiring harness connection position can specifically be a wiring harness via.

[0090] like Figure 6 As shown, the first button 33 and the second button 34 are installed side by side on one side of the trigger part 31 , and are connected to the connecting part 37 away from the first button 33 and the second button 34 , and a wiring harness connection can be performed in the connecting part 37 .

[0091] like Figure 7-9 As shown, each of the trigger parts 31 is provided with a shielding part 35, and the shielding part 35 shields the top of the trigger part 31. The shielding part 35 shields the top of the trigger part 31 to prevent other objects or unexpected actions in the environment from interfering with the operation of the trigger part 31. The shielding part 35 is assembled to avoid the user's feet horizontally, so as to allow the user's feet to horizontally extend into the trigger part 31 for stepping. In particular, it prevents the user from accidentally stepping on the trigger part 31 from other positions or incorrect angles. The shielding part 35 protects the trigger part 31 from unnecessary interference or improper use through a certain physical structure, while ensuring that the user can conveniently control it by pedaling during normal operation.

[0092] like Figure 7 As shown, the shielding portion 35 can be a frame structure, which includes two columns, which are located on both sides of the shielding portion 35 and connected to the trigger portion 31 at the lower ends. The columns support the shielding portion 35 to ensure that the shielding portion 35 can stably protect the trigger portion 31. A crossbeam is connected to the upper end of the column. The crossbeam fixes the two columns together to form a closed frame structure, thereby forming a shielding area above the trigger portion 31 to prevent the user from contacting the trigger portion 31 from above or other improper positions.

[0093] like Figure 8 , 9 As shown, the lower end of the shielding portion 35 is rotatably connected to the controller 30, and the shielding portion 35 can rotate around a certain axis, allowing the shielding portion 35 to rotate between different positions. The shielding portion 35 is provided with a retracting device, which can specifically be a lifting mechanism, a rotating mechanism, etc., which are all common types of retracting devices. The lifting mechanism refers to a system that realizes up and down movement by electric or mechanical means, while the rotating mechanism makes the shielding portion 35 rotate around a certain axis to realize the flexible switching of the shielding portion 35 between the two positions.

[0094] Specifically, the shielding portion 35 is rotatably connected to the controller 30 , and the retracting device is a motor transmission-connected to the shielding portion 35 .

[0095] The retractable device is used to drive the shielding portion 35 to switch between the following first position and second position:

[0096] like Figure 8 The first position is shown, and the shielding portion 35 shields the trigger portion 31. In this position, the shielding portion 35 mainly prevents the user from accidentally operating the trigger portion 31. It protects the trigger portion 31 from being accidentally stepped on, especially when the user may accidentally touch or step on it from other positions, the shielding portion 35 will block these improper operations.

[0097] like Fig. 9The second position is shown, and the shielding portion 35 avoids the top of the triggering portion 31. When the shielding portion 35 moves to the second position, it avoids the triggering portion 31, usually by moving the shielding portion 35 to the lower side or around the triggering portion 31. In this position, the shielding portion 35 will be embedded in the lower side of the controller 30 to avoid interfering with or hindering other operations of the user. This can effectively prevent the shielding portion 35 from becoming a stumbling block. Specifically, the shielding portion 35 no longer occupies too much space, avoiding obstacles caused by the shielding portion 35 not being enabled, and the design of being embedded in the lower side of the controller 30 allows the shielding portion 35 to be completely retracted and no longer protrudes, reducing any potential tripping risks.

[0098] It also includes an input unit, which is an interactive interface between the system and the user. It is responsible for receiving the user's input information (such as selection, operation instructions, etc.) and passing this information to the system so that the system can respond accordingly or perform certain operations. The user can send instructions to the system or select different options through the input unit to control the operation of the device or system. The input unit is used to obtain the user selection information, and the input unit includes a remote communication device or a touch screen arranged on the working unit 10. The remote communication device is specifically a tablet computer. The tablet computer is connected to the system through wireless communication (such as Wi-Fi or Bluetooth, etc.), allowing the user to send instructions or select operations through the tablet computer at any distance.

[0099] like Fig.10 As shown, the medical device control method includes the following steps:

[0100] S1. Obtain user selection information. The user selection information refers to information about which specific trigger unit 31 the user chooses to disable or enable on an input device such as a tablet.

[0101] The user makes a selection through a touch screen or tablet interface. For example, a set of switches or buttons may be displayed on the interface, with an option next to each trigger unit 31, and the user clicks the corresponding switch to enable or disable the trigger unit 31. These selections are captured by the input unit (such as a touch screen, tablet, etc.) and transmitted to the device control system.

[0102] S2. Enable or disable the trigger unit 31 according to the user selection information. When one trigger unit 31 is enabled, the other trigger units 31 are disabled. This means that there is a mutually exclusive relationship between the multiple trigger units 31 of the device, that is, only one component can be enabled at a time, avoiding conflicts or errors that may be caused by multiple components working at the same time.

[0103] The system checks the current state (enabled or disabled) of each trigger unit 31 according to the information selected by the user. If the user chooses to enable a component, the system will set the state of the component to enabled (for example, changing the electrical signal state of a switch) and simultaneously set the state of other trigger units 31 to disabled. This can be achieved by setting the control signal of the trigger unit 31, which can be a current, voltage, pulse signal, etc.

[0104] S3. Obtain the state information of the trigger unit 31, which includes an enabled state and a disabled state. The enabled state means that the trigger unit 31 is in an activated state and is ready to work; the disabled state means that the component is not activated and cannot perform an operation.

[0105] Each trigger unit 31 may have a sensor or switch device to detect its status. For example, an electrical signal may be used to determine whether the trigger unit 31 is in an enabled state (signal activated) or a disabled state (signal cut off or inactive). The status information is monitored in real time by the system and transmitted to the control system through a software algorithm to ensure that the status of the device is consistent with the user input.

[0106] S4. Control the indicator light 32 according to the state information of the trigger unit 31. The function of the indicator light 32 is to show the current state of the device to the user through visual signals. The state of the trigger unit 31 (enabled or disabled) will directly affect the display state of the corresponding indicator light 32. When the trigger unit 31 is enabled, the corresponding indicator light 32 is on; when the trigger unit 31 is disabled, the corresponding indicator light 32 is off.

[0107] Each trigger unit 31 is connected to an indicator light 32 (usually an LED light). The system controls the state of the light by controlling the circuit of the indicator light 32. The control signal is determined according to the state information of the trigger unit 31. This function can be achieved through a switch control circuit or digital signal control (for example, controlling a relay switch or controlling a PWM signal).

[0108] The indicator light 32 can also be changed according to the pedal state of the button, and the specific steps are:

[0109] The working state of the button is obtained, and the working state of the button includes a triggered state and an untriggered state. The system detects the state of the button in real time. The state of the button will affect the color or brightness of the indicator light 32. For example, when the button is triggered, the color of the indicator light 32 changes or the brightness increases, prompting the user that the device is in a certain working mode or state.

[0110] The color or brightness of the corresponding indicator light 32 is switched according to the working state of the button. If the button is in a triggered state, the color or brightness of the indicator light 32 can be changed by adjusting the control signal. The brightness of the indicator light 32 can be adjusted by controlling the RGB LED light or using PWM dimming. If the button is in an untriggered state, the indicator light 32 can be restored to a default state, usually off or showing another color.

[0111] S5. Control the action of the retracting and releasing device according to the status information of the trigger part 31, wherein when the trigger part 31 is in the enabled state, the corresponding shielding part 35 is driven to reach the first position, and when the trigger part 31 is in the disabled state, the corresponding shielding part 35 is driven to reach the second position.

[0112] The system controls the actions of these retractable and deployable devices according to the status information of the trigger unit 31 .

[0113] When in the enabled state, the system moves the shielding part 35 to the first position by controlling the action of the motor or cylinder of the retracting and unfolding device. This can be achieved by sending an electrical signal to a driving device (eg, a servo controller 30 or a stepper motor controller 30).

[0114] In the disabled state, the system controls the shielding portion 35 to move to the second position, which is usually accomplished by reversing the operation of the driving device.

[0115] The control of the retracting and extending device can use a closed-loop control system, such as a PID control algorithm, to ensure that the shielding part 35 accurately reaches the desired position.

[0116] like Figure 1 , 3 As shown, the above-mentioned medical equipment is placed in a treatment room, which includes a room 40, a first entrance 41 and a second entrance 42.

[0117] The medical equipment is placed in the room 40 .

[0118] The first entrance 41 is connected to the room 40. The first entrance 41 is used for operators of the medical equipment (specifically, doctors and nurses) to enter and exit, which means that they are the main users of the equipment.

[0119] The second entrance and exit 42 is connected to the room 40. The second entrance and exit 42 is used for non-operating personnel (specifically, patients and caregivers) to enter and exit. These personnel do not need to directly operate the equipment and are mainly used to provide services such as patient care.

[0120] The two sides of the bed 20 are respectively the first operating area and the second operating area, the first entrance 41 is arranged close to the first operating area, the second entrance 42 is arranged close to the second operating area, and the trigger part 31 in the enabled state can only be operated from the first operating area.

[0121] Operators (such as doctors or nurses) usually work in the first operating area, which is close to the first entrance 41, so that operators can directly operate the device after entering. Since the trigger part 31 in the enabled state can only be operated from the first operating area, and the first operating area is located in the area close to the first entrance 41, after entering the room 40, the operators basically work in the first operating area to ensure that their operation path and the position of the trigger part 31 are synchronized. The position of the trigger part 31 in the enabled state is designed in the first operating area to ensure that the operator can quickly and intuitively reach the trigger part 31 when operating the device without crossing unnecessary areas.

[0122] On the other hand, the second operation area is close to the second entrance 42, which means that non-operating personnel (patients or caregivers) mainly move in this area. Since the trigger unit 31 is not in the second operation area, non-operating personnel such as patients and caregivers will not touch the control part of the device after entering the second entrance 42, further reducing the possibility of misoperation.

[0123] In summary, the present invention proposes a medical device and a medical device control method. In the control system of the bed 20, a controller 30 that can only be operated on one side is set to prevent the bed 20 from accidentally moving due to the caregiver or doctor accidentally stepping on the controller 30 when the patient is being transported or positioned. While ensuring the convenience of operation, the safety of the bed 20 during movement is improved, the additional workload of doctors and nursing staff is reduced, and the risk of misoperation is reduced. Through the flexible configuration of the software, the device can adjust the operation mode in different situations (such as changes in operation requirements, special requirements of the medical environment, etc.). For example, in some cases, the operator may need to operate only from one side of the bed 20, and disabling the trigger part 31 on the other side can meet this requirement. The position setting of the controller 30 makes the staff usually consciously enter the area and step on the controller 30 when operating. The setting of this position relatively avoids unintentional operation. The existence of this interval reduces the contact between the staff and the controller 30. Compared with the controller 30 placed at other positions of the bed 20 or the working unit 10, such a design can effectively prevent mistouch.
