Description

Technical Field

[0001] The invention relates to medical equipment, and in particular to a medical accelerator module control box. Background Art

[0002] The existing medical accelerator module control box has an incomplete design for the isolation of strong and weak electricity, and the cable routing does not have strong and weak electricity isolation, which is prone to signal interference and poor insulation performance. When a circuit in the control box fails, it is necessary to disassemble the outer casing and then use maintenance equipment to measure the signal to determine the fault point. The operation is cumbersome and not convenient enough. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a medical accelerator module control box, which can achieve isolation of strong electricity and weak electricity and avoid signal interference. The functional circuit board is detachable for easy maintenance.

[0004] The medical accelerator module control box of the present invention comprises a box body, an electrical base plate and a plurality of functional circuit boards. The electrical base plate supplies power to each functional circuit board, and input / output signal connection lines are respectively arranged on the electrical base plate corresponding to each functional circuit board. The input / output signals of each functional circuit board are connected through the electrical base plate, and each functional circuit board is respectively connected to the corresponding input / output signal connection line through a rotatable gold finger slot.

[0005] The present invention arranges an electrical base plate in a box body, and the electrical base plate is used to connect an external power supply and various functional circuit boards. The electrical base plate converts the external power supply into the voltage required for the operation of each functional module through a power module, and transfers the weak current signal of each functional circuit board through the input / output signal connection line of the electrical base plate. The physical isolation of the strong current and weak current signal cables is achieved through the electrical base plate to avoid signal interference. The rotatable gold finger slot connects the various functional circuit boards and the electrical base plate. During installation, each functional circuit board can be vertically inserted into the rotatable gold finger slot, and then rotated to a horizontal position to be fixed to the electrical base plate. In case of failure, each functional circuit board can be independently disassembled, and maintenance is convenient.

[0006] The composition of the functional circuit board is determined by the functional modules of the control box. For example: if the control box is a dose detection control box, the functional circuit board mainly includes the ionization chamber power board, MCU board, dose integration board 1, and dose integration board 2; if the control box is a dose output control box, the functional circuit board mainly includes the MCU board, signal adapter board 1, signal adapter board 2, AFC circuit board, and modulator interface board. The circuit structure of each functional circuit board is the same as that of the existing functional circuit board, and no improvement has been made. Only the connection method of each functional circuit board has been adjusted, and a universal plug-in electrical base plate and wiring specifications are set.

[0007] Preferably, the rotatable gold finger slot comprises a fixed base, a base rotary sleeve, a gold finger rotary sleeve and a gold finger slot, one end of the fixed base is fixed to the electrical bottom plate, the other end of the fixed base is connected to the base rotary sleeve, one end of the gold finger rotary sleeve is coaxially sleeved in the base rotary sleeve, the gold finger rotary sleeve is fixedly connected to the bottom of the gold finger slot, and a gold finger terminal is correspondingly arranged on the gold finger slot, the gold finger terminal is connected to the electrical bottom plate through a wire, and the rotatable gold finger slot is fixed to the electrical bottom plate through the fixed base. During installation, each functional circuit board is inserted into the gold finger slot, and then the gold finger rotary sleeve is rotated. After each functional circuit board is adjusted to a horizontal position, it is fixed to the box body through a rubber shock absorber and screws. Wire threading holes are arranged on the gold finger rotary sleeve and the fixed base corresponding to the wires connected to the gold finger terminal to facilitate wiring.

[0008] Preferably, voltage signal lines are led out from some input / output signal lines on the electrical bottom plate, and each voltage signal line is connected to the LED lights of the LED display board. The current working status is displayed through different display arrays of the LED. The type of signal to be observed is determined by the functional module of the control box. For example: if the control box is a dose detection control box, the signals to be observed mainly include 3V voltage signal, ±15V voltage signal, ionization chamber voltage signal, voltage interlocking signal, dose over-tolerance signal, etc.; if the control box is a dose output control box, the signals to be observed mainly include 3V voltage signal, ±12V voltage signal, 24V voltage signal, main trigger signal, AFC signal, etc. Once an abnormal monitoring signal occurs, it will be displayed visually through the LED light for easy on-site observation. In order to facilitate relevant personnel to quickly lock the fault, the corresponding text description can be noted in the appropriate position of the box to indicate the fault type corresponding to the LED light on and off on the LED display board.

[0009] Preferably, the box includes a shell, an electrical bottom plate is fixed at the bottom of the shell, the shell is provided with an upward opening, a detachable cover is provided at the opening, and an observation window is provided at one side of the shell corresponding to the LED display board. A transparent acrylic panel is embedded in the observation window to protect and isolate the LED display board.

[0011] 1. The present invention integrates the electrical base plate, functional circuit board and LED display board into one, which is convenient for product production and debugging;

[0012] 2. Isolate strong and weak electricity through the electrical bottom plate to reduce signal interference and improve product insulation performance;
