The key is a commonly used element for controlling electric appliances, and is a switch which can achieve the purpose of controlling the operation of a motor or other electric equipment by using certain functions of a control machine or a program or connecting and disconnecting a control circuit. After the push switch is pressed for a long time or for a plurality of times, the phenomenon of jamming or adhesion can occur, or the push switch is pressed by a heavy object and can mistakenly touch the movement of a machine, so that the risk of injuring a user and damaging the machine exists. The inductive switch is sensitive and can penetrate through an insulating material housing (glass, plastic, etc.), and it is possible to trigger the control module as long as a finger is close to the switch even if the finger is not intended to be pressed. The press switch and the inductive switch have the risk of being opened by mistake when being used independently.
The present application provides a medical device comprising a diagnostic instrument and a key arrangement 1. The key device 1 is used for starting the diagnosis instrument to start diagnosis operation.

When the pressing module 11 is pressed, the pressing module 11 can send out a first signal; when the sensing module 12 is touched, the sensing module 12 can send out a second signal, wherein the first signal and the second signal are effective signals sent out when the pressing module 11 and the sensing module 12 are in working states; the detecting module 13 is used for detecting a first signal sent by the pressing module 11 and a second signal sent by the sensing module 12. Wherein, when the detection module 13 detects the first signal and the second signal, the control module 14 can control the medical apparatus to start. The risk that only the pressing module 11 or the sensing module 12 is set to be turned on by mistake to start the operation of the medical instrument is reduced.
In the embodiment of the application, when the pressing module 11 is pressed by a heavy object, the pressing module 11 sends out a first signal, the detection module 13 only detects the first signal, and the control module 14 cannot control the starting of the medical instrument; when the human hand touches the sensing module 12 but does not press the pressing module 11, the sensing module 12 sends a second signal, and the control module 14 cannot control the starting of the medical instrument when the detection module 13 only detects the second signal; when the human hand touches the sensing module 12 and presses the pressing module 11, the pressing module 11 sends a first signal, the sensing module 12 also sends a second signal, the detecting module 13 detects the first signal and the second signal, and the control module 14 controls the medical device to start. The sensing module 12 is added to the conventional pressing module 11, that is, the sensing module 12 senses the contact of the human body while the pressing module 11 is pressed, and the pressing module 11 and the sensing module 12 are triggered at the same time and send a signal to control the start of the medical device.
As shown in fig. 1, in one possible design, the detection module 13 includes a press detection unit 131 and an induction detection unit 132; the pressing detection unit 131 is configured to detect a first signal; the sensing detection unit 132 is used for detecting a second signal; when the pressing detection unit 131 detects the first signal and the sensing detection unit 132 detects the second signal, the control module 14 can control the medical device to start according to the detection result of the detection module 13. In this embodiment, when the pressing module 11 and the sensing module 12 are in the working state, the pressing detection unit 131 can detect the first signal, the sensing detection unit 132 can detect the second signal, and the first signal meets the second signal to form a start signal, which is transmitted to the control unit, so that the control unit controls the start of the medical device.
As shown in fig. 1, in one possible design, the key device 1 comprises a first conductor 15 and a second conductor 16; the sensing module 12 is connected with the sensing detection unit 132 through a first wire 15; the pressing module 11 and the pressing detection unit 131 are connected by the second wire 16. In this embodiment, the second signal sent by the sensing module 12 after being touched by the sensing human hand is transmitted to the sensing detection unit 132 through the first wire 15, and the first signal sent by the pressing module 11 after being pressed by the human hand is transmitted to the pressing detection unit 131 through the second wire 16. The sensing module 12 and the sensing detection unit 132 may be electrically connected or signal connected; the pressing module 11 and the pressing detection unit 131 may be electrically connected or may be connected by signals.
As shown in fig. 2, in one possible design, the sensing unit 132 includes a sensing chip 132 a; the sensing module 12 includes a touch sensing pad 121; when a human body contacts the touch sensing pad 121, the sensing chip 132a outputs a high level signal, so that the sensing module 12 sends a second signal. In the embodiment of the present application, the touch sensing pad 121 serves as a touch detection end, and when a human body contacts the touch sensing pad 121, an inductive capacitance formed by a hand of the human body and the ground is connected in parallel with an inductive capacitance formed by the touch sensing pad 121 and the ground, so that the inductive capacitance is increased. That is, when a human body contacts the touch sensing pad 121, the detection end of the sensing chip 132a senses the increase of the capacitance of the touch sensing pad 121 and outputs a high level signal through the output end of the sensing chip 132a, and the high level signal forms a second signal and transmits the second signal to the control unit.
In one possible design, the touch-sensitive pad 121 is made of metal. The touch sensing pad 121 may be made of copper. The copper material has wide application and is convenient to purchase.

In the embodiment of the application, the sensing module 12 is added above the traditional pressing module 11, and the sensing module 12 is touched while the pressing switch is pressed, so that signals sent by the pressing module 11 and the sensing module 12 form an effective signal to start the medical device to work. A spring is arranged between the pressing module 11 and the housing, so that the pressing module 11 and the sensing module 12 can return to the initial position in the housing after the hand of the human body leaves the pressing module 11 and the sensing module 12.
As shown in fig. 3, in one possible design, the key device 1 further comprises a protective layer 17 and an insulating isolation layer 18; the protective layer 17 is located above the sensing module 12, and the insulating isolation layer 18 is located between the sensing module 12 and the pressing module 11. In the embodiment of the present application, the protective layer 17 is used to isolate the sensing module 12 from the hand of the human body, and the insulating isolation layer 18 is used to isolate the sensing module 12 from the pressing module 11, so as to reduce the risk of the leakage of the medical device transmitted to the human body through the key device 1.
