Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
A kind of instrument human body of the utility model embodiment is apart from self-checking device as shown in Figure 1, described device centre
Manage unit 1 and the distance-measurement module 2 being connected with central processing unit 1, apart from adjustment module 3 and alarm module 4.Central processing
Unit 1 is used at a distance from 2 conjunction measuring instrument of distance-measurement module and human body, and is changed by command range adjustment module 3
The position of instrument, or triggering alarm module 4 prompt patient be moved forward and backward, make instrument fallen at a distance from human body setting away from
From in range.In the distance range of setting, instrument is harmless to human body and can human body effectively be treated or be detected.
In the present embodiment, described device is mainly by central processing unit 1, distance-measurement module 2, apart from adjustment module 3
It is formed with alarm module 4.Distance-measurement module 2 is used for the distance between 1 conjunction measuring instrument of central processing unit and human body.
There are many distance measuring method, and most common method is to carry out range measurement based on radio-positioning principle, such as laser ranging, ultrasound
Away from and infrared distance measuring.It is used to change under the control of central processing unit 1 position of instrument apart from adjustment module 3, to change
The distance between instrument and human body, until in the distance range that the distance falls in setting；Alarm module 4 is used in central processing
The lower prompt patient of the control of unit 1 is moved forward and backward, to change the distance between instrument and human body, until the distance is fallen in
In the distance range of setting.The distance range of setting be it is not only harmless but also human body effectively can be treated or be detected away from
From.It is generally realized by the way that the instrument carrying platform that one can be moved forward and backward is arranged apart from adjustment module 3.It can be based on electrical former
Reason is controlled, such as motor driven；It can also be controlled using pneumatic principle, such as Telescopic-cylinder.Alarm module 4 is general
Using sound circuit, prompt patient is recorded in advance and moves and move forward or behind how many audio signals.Change
The principle of distance is between instrument and human body: when the distance measured is fallen in the distance range of setting, not changing distance；Work as survey
Distance be less than setting distance range minimum value when, illustrate distance it is too close, instrument or people move backward, zoom out instrument and
Distance between human body, until meeting the requirements；When the distance measured is greater than the maximum value of the distance range of setting, illustrate distance too
Far, instrument or people move forward, and further distance between instrument and human body, until meeting the requirements.Alarm module 4 and apart from adjust mould
Block 3 can be used alone, and can also be used cooperatively.With the use of when with based on the adjustment module 3, even if when apart from adjusting mould
Block 3 makes instrument reach capacity position when can not make to fall at a distance from instrument and human body in the distance range of setting, restarts report
Alert module 4.
Preferably, the instrument measured when distance-measurement module 2 is L at a distance from human body, and the distance range set is most
When small value is L1, maximum value is L2, the position of following method conditioning instrumentation is pressed apart from adjustment module 3:
If L1 < L < L2, instrument do not move；
If L < L1, control instrument moves backward (L1+L2)/2-L；
If L > L2, control instrument moves forward L- (L1+L2)/2.
This gives quantitatively change the one of instrumented site under the control of central processing unit 1 apart from adjustment module 3
Kind technical solution.In the present embodiment, if the instrument measured is in the distance range that human body distance L falls in setting, it is not necessary to
Change instrumented site；If L is less than the minimum value L1 of the distance range of setting, instrument is made to move backward (L1+L2)/2-L, it is mobile
Distance afterwards becomes: L+ (L1+L2)/2-L=(L1+L2)/2, and distance at this time is located at the distance range center of setting, and approximation is most
Good distance.Similarly, if L be greater than setting distance range maximum value L2, make instrument move forward L- (L1+L2)/2 after away from
From the distance range center for also being located at setting, near optimal distance.
