Problems solved by technology

[0003] In order to overcome the shortcoming that nurses need to manually close the protective curtain every time someone comes in, it is very troublesome, and the main material of the protective curtain is lead. The shortcoming that nurses touch lead with hands for a long time is not good for the body. Technical problem: provide a Angiography machine protective curtain device control circuit that is easy to use and does not affect the nurse's body

Embodiment 1

[0020] Shields one kind angiography apparatus control circuit, such as figure 1 Shown, comprises a power supply unit 1, 2, or gate circuit, a third comparator circuit 3, a first position sensor 4, the second relay control circuit 5, a second potentiometer 6, a third potentiometer 7, motor 8 , the first amplifier circuit 9, a second amplifier circuit 10, a first potentiometer 11, the first relay control circuit 12, a fourth comparator circuit 13, a first indicator light 14, a photodiode 15 and a second position sensor 16, the an input terminal of said oR circuit output terminal 2 and the third comparator circuit 3 is connected to an output terminal of said third comparator circuit 3 and the first relay control circuit 12 is connected to the input terminal, the first relay control circuit an output terminal 12 of the DC motor 8 is connected to the control input of the first relay circuit 12 and the first position sensor 4 is connected to an input terminal or an output terminal of sa...

Embodiment 2

[0023] On the basis of Example 1, such as figure 1 FIG, 17 further comprises, a first output terminal circuit of the first illumination lamp lighting circuit 17 and the input terminal of the second amplifier circuit 10 is connected to the power supply unit 17 to supply a first lighting circuit.

[0024] In the case where light is not bright enough, the nurse may open the first lighting circuit 17, a first lighting circuit 17 lights up, improve the brightness at this time, the detection voltage is greater than the second amplifier circuit 10 in the reference voltage, the second amplifier circuit 10 output low, high, or the output of the gate circuit 2, a first relay control circuit 12 controls the DC motor 8 is transferred, the protective curtain closed, after the first position sensor 4 detects protective curtain closed, the DC motor 8 is closed.

Embodiment 3

[0026] Shields one kind angiography apparatus control circuit, such as figure 2 Shown, the OR circuit 2 comprises a dual operational amplifier LM358-U1, RGl photodiodes, resistors R3 and R5, the dual op amp LM358-U1 pin 3, pin 6 is connected thereto, said dual operational amplifier LM358 -U1 8 feet to + 12V, the dual operational amplifier LM358-U1 pin 4 of the series resistor R3, a resistor R5 and the anode of RG1 photodiode, the photodiode connected to the cathode of RG1 + 12V.

[0027] Said second potentiometer to potentiometer VR3 6, one end of said dual op amp LM358-U1 pin 4 and potentiometer VR3 is connected to the end of an adjustable potentiometer VR3 and a dual op amp LM358-U1 pin 5 connect.

Abstract

The invention relates to the field of medical instruments and particularly relates to a control circuit for a protective curtain device of an angiography machine. A technical problem is to provide the control circuit for the protective curtain device of the angiography machine, which is convenient to use and does not affect the body of a nurse. The control circuit for the protective curtain device of the angiography machine comprises a power supply unit, an OR gate circuit, a third comparator circuit and the like; wherein an output end of the OR gate circuit is connected with an input end of the third comparator circuit. Through the action of the photosensitive diode, the direct current motor can be automatically controlled to work, the protective curtain is opened or closed, manual operation of a nurse is not needed, the control circuit is convenient to use, and the body of a nurse cannot be affected.

Description

Technical field [0001] The present invention relates to the field of medical devices, particularly to a protective curtain angiography device control circuit. Background technique [0002] Angiography is a new X-ray imaging system is a conventional angiography and computer image processing technology combined with the product, mainly for general inspection and X-ray angiography, angiography is in operation at, need to use protective curtain cover, every time someone came in, we need nurses to manually shut down the protective curtain, very troublesome, and the main material protective curtain of lead, lead nurse hands away from long-term poor health, so the design of a kind of easy to use, angiography machine protective curtain device will not affect the nurse's body control circuit. Inventive content [0003] In order to overcome each time someone came in, we need nurses to manually shut down the protective curtain, very troublesome, and the main material protective curtain of ...
