As shown in FIG. 1 , an embodiment of the present invention provides a detection device 100 for detecting possible faulty components in medical equipment, especially electrical and electronic components.

As shown in FIG. 1 , the detection device 100 includes an interface 110 , an analog device 120 , and a feedback device 130 .

Wherein, the interface 110 is used to connect the interface of the port in the medical device to be detected (not shown in the figure), and may be one or more of the following interfaces: Analogue Input&Output, Digital Input&Output ), CAN bus interface, Ethernet interface, universal serial bus (USB) interface, RS232 interface, RS485 interface, integrated circuit bus (I2C, Inter-integrated Circuit) interface, serial peripheral interface (SPI, Serial Peripheral Interface) Interface, Synchronous Serial Interface (SSI, Synchronous Serial Interface) interface.

The interface 110 can be connected to a port of the medical device to be tested that is connected to electrical and electronic components such as sensors, brakes, clutches, relays, buttons, switches, and control boards.

After the interface 110 is connected to the port of the medical device to be detected, it can receive signals from the port of the medical device to be detected and transmit it to the analog device 120, or send the signal from the analog device 120 to the port with the medical device to be detected.

The simulation device 120 is configured to generate a component output signal, the simulation device 120 receives a signal from the medical device to be tested through the interface 110, converts the signal and sends it to the feedback device 130, so that the feedback device 130 provides feedback to the user. Alternatively, the simulation device 120 sends the signal generated by the simulation device to the medical device to be detected through the interface 110 . Of course, the simulation device 120 may simultaneously have the above two structures and functions.

The feedback device 130 provides feedback to the user based on the signal from the analog device. For example, the feedback device 130 may be a signal light. When the analog device 120 signal indicates normal, the feedback device 130 lights up a green light, and when the analog device 120 signal indicates a fault, the feedback device 130 lights up a red light.

The detection device 100 may also include a battery to power the detection device itself. In addition, as shown in FIG. 2 , the detection device may also include a power interface 140 , the power interface is used for an external power supply, and the detection device is provided with power through the power supply. If the detection device includes both a battery and a power interface 140, preferably the battery is a rechargeable battery, and the power interface 140 can also use an external power source to charge the internal battery.

FIG. 2 shows a detection apparatus 100 according to another embodiment of the present invention.

The interface 110 of the detection device 100 includes: an analog input and output end 112, a digital input and output end 114, a CAN bus interface, an Ethernet interface 116, a USB interface, an RS232 interface, an RS485 interface, an I2C interface, an SPI interface, an SSI interface, and the like. This design can basically connect all electrical and electronic ports on the medical device to be inspected, thus providing comprehensive inspection technology. These interfaces are all connected to the analog device 120 . In FIG. 2 , the connection lines between the interface 110 and the analog device 120 are omitted for the purpose of avoiding too many connecting lines to make the drawing unclear.

As shown in FIG. 2 , the feedback device 130 includes an LED display screen.

In the detection apparatus 100 shown in FIG. 2 , the simulation device 120 includes a computing device 122 and a memory 124 . A simulation program is stored in the memory 124 . The computing device 122 converts the received signal into an analog program identifiable signal, and converts the analog program output signal into an analog device corresponding interface output signal.

The simulation device 120 can download the simulation program to the memory from a connected USB memory card. In this way, the simulation program in the testing device 100 can be updated to adapt to different medical devices to be tested, especially new medical devices.

According to another embodiment, the memory 124 can be accessed by a computer and modify the simulation program in the memory 124 . In other words, with this structure and technology, the user can access and modify and update the simulation program in the memory 124 through the computer, and can also adapt to different medical equipment to be tested, especially new medical equipment.

In one embodiment, the detection device 100 of the embodiment of the present invention is further described by taking the detection of a position encoder in an X-ray machine of a medical device as an example. Position encoders are often used to measure the position of a moving part, such as the position of an X-ray tube. In the case of wrong position information, the most common failure situations are: the position encoder fails, and the cable connecting the position encoder fails.

First check the position encoder. Unplug the position encoder from the X-ray machine (specifically, the cable connecting the position encoder), and connect the port of the position encoder to the corresponding interface 110 of the detection device 100, such as an RS485 interface or an SSI interface. After the position encoder is in operation, the generated position signal is sent to the interface 110 of the detection device 100 . After receiving the position signal from the position encoder through the interface 110, the simulation device 120 of the detection device 100 converts the position signal into position information and sends it to the feedback device 130, such as an LED display screen, to display the position information on the LED display screen. The service engineer can judge whether the position encoder is faulty according to whether the position information on the LED display is correct.

If the position encoder is normal, the cable can be further detected. Reconnect the position encoder to the cable, unplug the other end of the cable (the end connected to the X-ray machine), and connect it to the corresponding interface 110 of the detection device 100 . After the position encoder runs, the generated position signal is sent to the interface 110 of the detection device 100 through the cable to be detected. After the position signal passes through the cable to be detected, the analog device 120 of the detection device 100 receives the position signal from the position encoder through the interface 110, converts the position signal into position information, and sends it to the feedback device 130, such as an LED display, to convert the position signal into position information. Information is displayed on the LED display. The service engineer can judge whether the position encoder is faulty according to whether the position information on the LED display is correct. For example, if the LED display shows the correct position information, it can be inferred that the position encoder and the cable are normal; if the LED display does not display the correct position information, since it has been previously determined that the position encoder is normal, it can be inferred from this The outgoing cable is faulty.

In another embodiment, the position encoder is unplugged from the X-ray machine (specifically, the position encoder can be unplugged from the cable, or the cable connected with the position encoder can be unplugged from the X-ray machine. On the machine), connect the port vacated after the position encoder is removed from the X-ray machine to the corresponding interface 110 of the detection device. After the detection device 100 runs, the simulation device 120 simulates the position encoder, generates the position signal output by the position encoder, and sends it to the X-ray machine to be detected through the interface 110, specifically the control board in the X-ray machine, or Sampling circuit in the control board. If the software in the X-ray machine can correctly display the position information, it can be inferred that the sampling circuit is normal; if the software in the X-ray machine cannot correctly display the position information, it can be inferred that the sampling circuit is faulty.
