Description

TECHNICAL FIELD

Figure 4The circuit principle diagram of the wireless receiving circuit; further, the wireless transmitting circuit comprises a wireless remote control transmitting head IC1, a wireless remote control encoder and a switch control circuit, the wireless remote control encoder comprises an 8-bit four-state address encoding integrated circuit IC2, a resistor R5 and a capacitor C, the switch control circuit comprises control buttons S1, S2 and S3, resistors R1, R2, R3 and R4, diodes VD1, VD2, VD3 and VD4, a voltage stabilizing diode VS and a light emitting diode VL; the control button S1 is connected to the first pin of the 8-bit four-state address encoding integrated circuit IC2 through the diode VD1 and grounded through the resistor R1; the control button S2 is connected to the second pin of the 8-bit four-state address encoding integrated circuit IC2 through the diode VD2 and grounded through the resistor R2; the control button S3 is connected to the third pin of the 8-bit four-state address encoding integrated circuit IC2 through the diode VD3 and grounded through the resistor R3; the output end of the 8-bit four-state address encoding integrated circuit IC2 is connected to the wireless remote control transmitting head IC1 through the resistor R6;

[0043] The wireless receiving circuit comprises a wireless remote control receiving head IC3, a wireless remote control decoder and a control execution circuit, the wireless remote control decoder comprises a resistor R7 and a decoder integrated circuit IC4; the control execution circuit comprises transistors V1, V2 and V3, relays K1, K2 and K3, diodes VD4, VD5 and VD6, resistors R8, R9 and R10; the input end of the wireless remote control receiving head IC3 is connected to the decoder integrated circuit IC4, the first pin of the decoder integrated circuit IC4 is connected to the light emitting diode VD4 through the resistor R8, the transistor V1 and the relay K1, the second pin of the decoder integrated circuit IC4 is connected to the light emitting diode VD5 through the resistor R9, the transistor V2 and the relay K2, and the third pin of the decoder integrated circuit IC4 is connected to the light emitting diode VD6 through the resistor R9, the transistor V3 and the relay K3.

[0044] Specifically, the wireless remote control device 6 is provided with control buttons S1, S2 and S3, and medical staff can control the wireless remote control device 6. When the control button S1, S2 or S3 is selected, the 8-bit four-state address coding integrated circuit IC2 decodes the operation and transmits it through the built-in antenna of the wireless remote control transmitter IC1. After the wireless remote control receiver IC3 receives the coded instruction signal transmitted by the wireless remote control transmitter IC1 through the built-in antenna, it first performs internal demodulation, amplification and shaping, and then sends it to the decoder integrated circuit IC4 for decoding processing. When the coded instruction information is consistent with the data set by the decoder integrated circuit IC4, the corresponding data output end of the decoder integrated circuit IC4 outputs a high level, making the transistor saturated and conducting, the relay attracted, and the controlled electric appliance powered on. For example, when the control button S1 is pressed, the D0 end of the decoder integrated circuit IC4 outputs a high level at pin 10, making the transistor V1 saturated and conducting, the relay K1 attracted, and the normally open contact of the relay K1 connecting the power supply of the controlled electric appliance, and the light-emitting diode VD4 lighting up. The diode VD4 corresponds to the first signal lamp, and the first signal lamp is lit or flashed, reminding the examinee to inhale according to the inhale indication 111 of the first display area 11. Similarly, the control button S2 controls the diode VD5 (second signal lamp) to light up or flash, reminding the examinee to hold breath according to the hold breath indication 121 of the second display area 12, and the control button S3 controls the diode VD5 (third signal lamp) to light up or flash, reminding the examinee to exhale according to the exhale indication 131 of the third display area 13.

[0045] In some embodiments of the present application, the display part 1 can be a display screen, which can play moving pictures. The inhale indication 111 is an inhale moving picture, the hold breath indication 121 is a hold breath moving picture, and the exhale indication 131 is an exhale moving picture. The first signal lamp works simultaneously with the inhale moving picture, the second signal lamp works simultaneously with the hold breath moving picture, and the third signal lamp works simultaneously with the exhale moving picture.

[0046] Specifically, in order to facilitate understanding, the inhale indication 111 is set as an inhale moving picture, the hold breath indication 121 is set as a hold breath moving picture, and the exhale indication 131 is set as an exhale moving picture. When the first signal lamp is lit or flashed, the inhale moving picture starts to play, reminding the examinee to inhale at this time. When the second signal lamp is lit or flashed, the hold breath moving picture starts to play, reminding the examinee to hold breath at this time. When the third signal lamp is lit or flashed, the exhale moving picture starts to play, reminding the examinee to exhale at this time.

[0047] Please refer to Figure 5 , Figure 5Another structural schematic view of the indication device for standing MRI examination. In some embodiments of the present application, a support part 3 for supporting the display part 1 is further included, and the display part 1 comprises three arc-shaped display panels, any one of which is provided with a first display area 11, a second display area 12 and a third display area 13, and the three arc-shaped display panels are connected to the support part 3 through a connecting part 4 respectively, and the three arc-shaped display panels are arranged around the support part 3.

[0048] Specifically, the three arc-shaped display panels are not independent, but are connected to the support part 3 through the connecting part 4. The design of the connecting part 4 ensures that the arc-shaped display panels can be stably fixed on the support part 3 and can be adjusted when needed. More importantly, the three arc-shaped display panels are arranged around the support part 3, forming a display interface similar to a ring. Through such a setting, the three arc-shaped display panels can provide guidance information for MRI examination for three examinees at the same time. During an MRI examination process, three examinees can be accommodated and examined at the same time, greatly improving the examination efficiency.

[0050] Specifically, the positioning member 5 is a component for fixing or locking the position of the arc-shaped display panel on the support part 3. When it is necessary to adjust the position or angle of the arc-shaped display panel, the positioning member 5 can be loosened; and after the appropriate position is determined, the positioning member 5 is used again to fix it. By inserting the sliding block on the arc-shaped display panel into the sliding groove 31 of the support part 3, the sliding connection of the arc-shaped display panel with the support part 3 is realized. This connection allows the arc-shaped display panel to move freely on the support part 3 until the desired position is reached. Once the arc-shaped display panel is moved to the desired position, the positioning member 5 is used to fix the arc-shaped display panel to prevent it from moving. The positioning member 5 can be a locking device such as a screw, a buckle or a spring lock, etc., which can tightly fit between the sliding block and the sliding groove 31 to ensure the stability of the arc-shaped display panel.
