Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a control device for a mobile medical imaging device and a mobile medical imaging device. Background Art

[0002] A mobile medical imaging device, such as a mobile X-ray machine, is a mobile medical imaging device that uses battery technology for auxiliary driving and can perform complete X-ray imaging. It is widely used for the examination and diagnosis of human body parts. In the existing mobile X-ray machines, when the device fails and the electric assist for pushing is limited, for example, when the device power supply cannot supply power, the wheel brake device cannot be unlocked and the device cannot be pushed and moved. To address this problem, most of the current solutions are mechanical brake release methods, that is, a professional maintenance personnel needs to use tools to remove the mechanical transmission connection between the wheel (or the wheel brake device) and the motor, push the device to the repairable area for repair, and then use tools to restore the transmission connection between the wheel (or the wheel brake device) and the motor to resume the use of the device. The current solutions require mechanical removal to restore the device when the wheel brake device is locked, resulting in too long a downtime recovery time for the device.

[0045] An embodiment of the present application provides a control device for a mobile medical imaging device. Figure 1 It is a schematic structural diagram of a control device 100 for a mobile medical imaging device according to an embodiment of the present application. As Figure 1 shown, the control device 100 includes a first switch 101, a second switch 102, and a control circuit 103; a first end of the first switch 101 is connected to a motor 400 of the mobile medical imaging device, a second end of the first switch 101 is connected to a first power supply 510 of the mobile medical imaging device, and a third end of the first switch 101 is connected to the control circuit 103; one end of the second switch 102 is connected to the first power supply 510 of the mobile medical imaging device, and the other end of the second switch 102 is connected to a braking device 310 of the mobile medical imaging device; the control circuit 103 is also respectively connected to the first power supply 510 and the braking device 310 of the mobile medical imaging device, that is, the first power supply 510, the control circuit 103, and the braking device 310 are connected in series.

[0046] Among them, the mobile medical imaging device includes a motor 400, a first power supply 510, wheels 300, and the control device 100 in this embodiment. The motor 400 is mechanically connected to the wheels 300. The motor 400 drives the wheels 300 to move, realizing the movement or locomotion of the mobile medical imaging device. The control circuit 103 is connected to the first power supply 510, and the first power supply 510 supplies power to the control circuit 103. A braking device 310 is provided on the wheels 300. The braking device 310 is used to restrict the movement of the wheels 300. The control circuit 103 is electrically connected to the braking device 310. When the mobile medical imaging device needs to brake, the control circuit 103 controls the braking device 310 to mechanically connect the braking device 310 and the motor 400, locking the braking device 310, thereby locking the wheels 300 and restricting the movement or locomotion of the mobile medical imaging device. When the mobile medical imaging device needs to continue moving, the control circuit 103 controls the braking device 310 to release the mechanical connection between the braking device 310 and the motor 400, unlocking the braking device 310, thereby unlocking the wheels 300 and restoring the movement or locomotion of the mobile medical imaging device. As a non-limiting implementation, a first electromagnetic structure is provided on the braking device 310. When the braking device 310 is not powered on, the first electromagnetic structure on the braking device 310 drives the braking device 310 to adsorb on the motor 400, thereby locking the wheels 300, achieving the effect of locking the mobile medical imaging device and restricting the movement or locomotion of the mobile medical imaging device. When it is necessary to unlock the mobile medical imaging device, the control circuit 103 controls the first electromagnetic structure on the braking device 310, such as electrically controlling the first electromagnetic structure to be powered on, so that the first electromagnetic structure disconnects the mechanical connection with the motor 400, thereby unlocking the wheels 300, unlocking the mobile medical imaging device, and restoring the movement or locomotion of the mobile medical imaging device. As another non-limiting implementation, a first electromagnetic structure is provided on the braking device 310 and a second electromagnetic structure is provided on the motor 400. When the braking device 310 and the motor 400 are not powered on, the first electromagnetic structure on the braking device 310 adsorbs on the second electromagnetic structure on the motor 400, so that the braking device 310 and the motor 400 are locked together, thereby locking the wheels 300, achieving the effect of locking the mobile medical imaging device and restricting the movement or locomotion of the mobile medical imaging device. When it is necessary to unlock the mobile medical imaging device, the control circuit 103 controls the first electromagnetic structure on the braking device 310 and the second electromagnetic structure on the motor 400, such as electrically controlling the first electromagnetic structure and the second electromagnetic structure to be powered on, so that the first electromagnetic structure disconnects the mechanical connection with the second electromagnetic structure, thereby unlocking the wheels 300, unlocking the mobile medical imaging device, and restoring the movement or locomotion of the mobile medical imaging device.The locking here can be understood as restricting the movement or mobility of the braking device 310, the wheel 300, and the mobile medical imaging device. The control circuit 103 here can be implemented by a single-chip microcomputer, a digital signal processing unit DSP, a field programmable gate array FPGA, etc., and no specific limitation is made here. The first power supply 510 here can be the power supply for the entire mobile medical imaging device inside the mobile medical imaging device. The first power supply 510 can be a rechargeable battery or a charging battery, and no specific limitation is made here.

[0047] The first switch 101 is a three-terminal switch. The control terminal, i.e., the third terminal, of the first switch 101 is connected to the control circuit 103. The control circuit 103 controls the conduction degree of the first switch 101 through the third terminal, so as to control whether the first power supply 510 supplies power to the motor 400, and control the supply voltage and supply current of the motor 400, thereby adjusting the rotation speed and torque of the motor 400, realizing the control of the movement or mobility of the mobile medical imaging device, and realizing the speed and direction of the movement or mobility of the mobile medical imaging device. As a non-limiting implementation manner, the first switch 101 here can adopt a field effect transistor, such as an NMOS transistor or a PMOS transistor. For example, the gate of the field effect transistor is connected to the control circuit 103, the drain of the field effect transistor is connected to the first power supply 510, and the source of the field effect transistor is connected to the motor 400. Another example is that the gate of the field effect transistor is connected to the control circuit 103, the source of the field effect transistor is connected to the first power supply 510, and the drain of the field effect transistor is connected to the motor 400. No specific limitation is made here.

[0048] The second switch 102 is a two-terminal switch, one end of the second switch 102 is connected to the first power source 510, and the other end of the second switch 102 is connected to the brake device 310. The second switch 102 here can be a manual switch. When the brake device 310 and the motor 400 are locked and the mobile medical imaging device cannot be moved, the second switch 102 is manually closed. After closing, the first power source 510 can supply power to the brake device 310. As another non-limiting embodiment, a first electromagnetic structure is provided on the brake device 310. When the brake device 310 is not powered, the first electromagnetic structure on the brake device 310 drives the brake device 310 to be adsorbed on the motor 400, thereby locking the wheel 300, thereby achieving the effect of locking the mobile medical imaging device and limiting the movement or motion of the mobile medical imaging device. When the mobile medical imaging device needs to be unlocked, the control circuit 103 controls the first electromagnetic structure on the brake device 310, such as electrically controlling the first electromagnetic structure to be energized, thereby disconnecting the mechanical transmission connection between the first electromagnetic structure and the motor 400, thereby unlocking the wheel 300, unlocking the mobile medical imaging device, and restoring the movement or motion of the mobile medical imaging device. When the control device 100 or the control circuit 103 of the mobile medical imaging device fails, the control circuit 103 cannot electrically control the first electromagnetic structure on the brake device 310, and the first electromagnetic structure on the brake device 310 drives the brake device 310 to be adsorbed on the motor 400, and the mobile medical imaging device is locked and cannot move or exercise. When the user cannot push the mobile medical imaging device, the second switch 102 is manually closed. At this time, the first power supply 510 supplies power to the brake device 310. After the first electromagnetic structure on the brake device 310 is energized, the first electromagnetic structure disconnects the mechanical transmission connection with the motor 400, thereby releasing the lock of the wheel 300, releasing the lock of the mobile medical imaging device, and restoring the movement or motion of the mobile medical imaging device. After the brake is released, the mobile medical imaging device can be manually moved to the target location for fault repair.

[0049] The control device 100 of this embodiment includes a first switch 101, a second switch 102, and a control circuit 103; the first end of the first switch 101 is connected to the motor 400 of the mobile medical imaging device, the second end of the first switch 101 is connected to the first power supply 510 of the mobile medical imaging device, and the third end of the first switch 101 is connected to the control circuit 103; one end of the second switch 102 is connected to the first power supply 510 of the mobile medical imaging device, and the other end of the second switch 102 is connected to the braking device 310 of the mobile medical imaging device; the control circuit 103 is also connected to the braking device 310 of the mobile medical imaging device. Through the setting of the second switch 102, when a fault occurs in the mobile medical imaging device, the braking device 310 is powered by the second switch 102 to release the locking of the braking device 310. The control device 100 of the embodiment of the present application does not need to adopt a mechanical removal method to restore the device, thereby solving the problem that the existing solution requires a mechanical removal method to restore the device when the braking device 310 of the wheel 300 is locked, resulting in too long a downtime recovery time of the device.

[0066] In this embodiment, by enabling the backup power supply to energize the braking device 310 to release the lock of the wheel 300, it is not necessary to use the mechanical removal method to restore the device, thus solving the problem that the existing solution requires the mechanical removal method to restore the device when the wheel 300 braking device 310 is locked, resulting in too long downtime recovery time of the device.

[0067] In the embodiment of the present application, a control device for a mobile medical imaging device is also provided. Figure 8 It is a schematic structural diagram of another control device for a mobile medical imaging device according to the embodiment of the present application. As Figure 8 shown in the figure, the control device 100 includes a first switch 101, a second switch 102, a second transformer 105, a second diode D2, and a control circuit 103. The first end of the first switch 101 is connected to the motor 400 of the mobile medical imaging device. The second end of the first switch 101 is connected to the first power supply 510 of the mobile medical imaging device. The third end of the first switch 101 is connected to the control circuit 103. One end of the second switch 102 is connected to the first power supply 510 of the mobile medical imaging device. The other end of the second switch 102 is connected to the braking device 310 of the mobile medical imaging device. The input end of the second transformer 105 is connected to the second power supply 520 of the mobile medical imaging device. The output end of the second transformer 105 is connected to the positive electrode of the second diode D2. The negative electrode of the second diode D2 is connected to one end of the second switch 102. The control circuit 103 is also connected to the first power supply 510 and the braking device 310 of the mobile medical imaging device respectively.

[0068] In this embodiment, a diode is provided between the transformer and the second switch 102 to prevent voltage backflow.

[0069] An embodiment of the present application also provides a control device for a mobile medical imaging device. Figure 9 As shown in Figure 9 Figure 5, the control device 100 includes a first switch 101, a second switch 102, a power interface 109, and a control circuit 103; a first end of the first switch 101 is connected to a motor 400 of the mobile medical imaging device, a second end of the first switch 101 is connected to a first power supply 510 of the mobile medical imaging device, and a third end of the first switch 101 is connected to the control circuit 103; one end of the second switch 102 is connected to the first power supply 510 of the mobile medical imaging device, and the other end of the second switch 102 is connected to a braking device 310 of the mobile medical imaging device; the power interface 109 is connected to one end of the second switch 102; the control circuit 103 is also connected to the first power supply 510 and the braking device 310 of the mobile medical imaging device respectively.

[0070] The power interface 109 is used to connect to a third power supply 530 of the mobile medical imaging device, and the third power supply 530 here may be an external power supply of the mobile medical imaging device, such as a portable power supply, etc.

[0071] In this embodiment, by connecting the external power supply of the mobile medical imaging device through the power interface 109 and energizing the braking device 310, the wheel 300 is unlocked, and there is no need to use a mechanical removal method to restore the device, thus solving the problem that in the existing solution, when the braking device 310 of the wheel 300 is locked, a mechanical removal method needs to be used to restore the device, resulting in too long a downtime recovery time of the device.

[0072] In some of these embodiments, continuing to refer to Figure 9 Figure 5, the control device 100 further includes a third transformer 106; an input end of the third transformer 106 is connected to the power interface 109, and an output end of a second transformer 105 is connected to one end of the second switch 102. Among them, the model of the second transformer 105 can be determined according to the voltage range of the external power supply and the voltage range of the second switch 102.

[0073] In this embodiment, a third transformer 106 is provided between the second switch 102 and the external power supply to perform voltage transformation on the external power supply. By selecting the model of the third transformer 106, the voltage of the external power supply is adapted to the second switch 102, thereby improving the selectivity of the model of the second switch 102.

[0074] In some of these embodiments, continuing to refer to Figure 9, the control device 100 further includes a third diode D3; the positive electrode of the third diode D3 is connected to the output terminal of the third transformer 106, and the negative electrode of the third diode D3 is connected to one end of the second switch 102.

[0075] In this embodiment, by setting a diode between the transformer and the second switch 102, voltage backflow is prevented.

[0076] An embodiment of the present application also provides a control device for a mobile medical imaging device. Figure 10 It is a schematic structural diagram of another control device for a mobile medical imaging device according to an embodiment of the present application. As Figure 10 shown, the control device 100 includes a first switch 101, a second switch 102, a second transformer 105, a third transformer 106, a fourth transformer 107, a fifth transformer 108, a second diode D2, a third diode D3, a fourth diode D4, a fifth diode D5, a power interface 109, and a control circuit 103; the first end of the first switch 101 is connected to the motor 400 of the mobile medical imaging device, the second end of the first switch 101 is connected to the first power supply 510 of the mobile medical imaging device, and the third end of the first switch 101 is connected to the control circuit 103; the input terminal of the fifth transformer 108 is connected to the first power supply 510, the output terminal of the fifth transformer 108 is connected to the control circuit 103, and the control circuit 103 is connected to the braking device 310; the output terminal of the fifth transformer 108 is further connected to the positive electrode of the fifth diode D5, the negative electrode of the fifth diode D5 is connected to one end of the second switch 102, and the other end of the second switch 102 is connected to the braking device 310; the input terminal of the fourth transformer 107 is connected to the first power supply 510, the output terminal of the fourth transformer 107 is connected to the positive electrode of the fourth diode D4, and the negative electrode of the fourth diode D4 is connected to one end of the second switch 102; the input terminal of the second transformer 105 is connected to the second power supply 520, the output terminal of the second transformer 105 is connected to the positive electrode of the second diode D2, and the negative electrode of the second diode D2 is connected to one end of the second switch 102; the input terminal of the third transformer 106 is connected to the third power supply 530 through the power interface 109, the output terminal of the third transformer 106 is connected to the positive electrode of the third diode D3, and the negative electrode of the third diode D3 is connected to one end of the second switch 102.

[0077] Among them, the brakes of the wheels 300 cannot be electrically unlocked, and the device cannot be pushed. Press the second switch 102 to switch to manual unlocking, and start the first power supply 510, the transformer (the fifth transformer 108 or the fourth transformer 107), or the backup power supply circuit to release the brakes. When the first power supply 510 and the backup power supply cannot release the brakes, an external portable mobile power supply (i.e., the third power supply 530) is used to release the brakes. For movable medical devices with brake units, the brakes can be electrically released by switching the power supply. The control device 100 in this embodiment can use the method of electrically unlocking the brakes to unlock the brakes of the wheels 300. When the electric assist pushing of the wheels 300 of the mobile medical imaging device is limited, there is no need to disassemble the transmission mechanism of the wheels 300. By switching the power supply of the brakes through a button or a switch, the brakes of the wheels 300 can be electrically unlocked, and the device can be pushed again. The switched power supply can be the output of the voltage conversion of the power battery of the mobile medical imaging device itself, or it can be an internal backup battery. At the same time, an interface for a portable mobile power supply is added, and an external power input interface is reserved, which is convenient for using other external power supplies to quickly electrically unlock the brakes of the wheels 300, greatly reducing the recovery time of the device under such fault conditions, and there is no need for professional maintenance personnel to perform disassembly and assembly operations, greatly improving the serviceability of the device.

[0078] In this embodiment, by setting the second switch 102, the second power supply 520, and the third power supply 530, when a fault occurs in the mobile medical imaging device, the brake device 310 is powered by the second switch 102 to release the lock of the brake device 310. The solution of the embodiment of the present application does not require mechanical disassembly to restore the device, thereby solving the problem that the existing solution requires mechanical disassembly to restore the device when the brake device 310 of the wheels 300 is locked, resulting in too long a downtime recovery time of the device.

[0079] An embodiment of the present application also provides a mobile medical imaging device. Figure 11 It is a schematic structural diagram of a mobile medical imaging device according to an embodiment of the present application, as Figure 11 shown. The mobile medical imaging device includes a vehicle body 200 and wheels 300. Inside the vehicle body 200, there are a motor 400, a first power supply 510, a second power supply 520, and the control device 100 in the foregoing embodiment. The mobile medical imaging device further includes an X-ray detector 610, a collimator 620, a tube 630, a column 700, and a telescopic arm 800.

[0080] In the mobile medical imaging device of this embodiment, by setting the second switch 102, the second power supply 520, and the third power supply 530, when a failure occurs in the mobile medical imaging device, the braking device 310 is powered by the second switch 102 to release the locking of the braking device 310. The solution of the embodiment of the present application does not require mechanical disassembly to restore the device, thus solving the problem that the existing solution requires mechanical disassembly to restore the device when the braking device 310 of the wheel 300 is locked, resulting in too long a downtime recovery time of the device.

[0081] The working flow chart of the mobile medical imaging device in the embodiment of the present application is as Figure 12 shown. The electric unlocking of the wheel brake cannot be performed, and the device cannot be pushed; press the button to switch to manual unlocking; start the vehicle body power circuit or the backup battery circuit to release the brake; or, connect an external portable mobile power supply to release the brake; after the brake is released, the device can be pushed. Among them, the button is the second switch 102, the vehicle body power circuit refers to the circuit that accesses the first power supply 510 using the second switch 102, the backup battery circuit refers to the circuit that accesses the second power supply 520 using the second switch 102, and the external portable mobile power supply is the third power supply 530.
