Definitions

  • the invention relates to a device for manual, contactless actuation of an electrical device, which should not be touched to actuate it, in particular for reasons of sterility or cleanliness.
  • DE 19623 104 A1 describes a sanitary fitting designed as a single-lever mixer and the integration of a proximity sensor for contactless actuation of the fitting.
  • an electrically controllable valve is provided, by means of which a signal generated by the proximity sensor actuates an electromagnetic closing mechanism.
  • the proximity sensor can only generate a one-time signal, namely when, for example, a hand is in close proximity to the sensor. As a result, only an opening signal is generated, possibly a closing signal for the water tap.
  • DE 41 26 168 A1 describes a protection against accidental contact for medical diagnostic or therapeutic devices.
  • a spatially positionable device part is equipped with a non-contact sensor, so that movement of the device part towards an object is prevented as soon as a certain minimum distance between the object and the device part is undershot.
  • the sensor device described in this document which contains two sensors which respond to electromagnetic fields, is intended, for example, to prevent collisions from occurring when an X-ray image intensifier is spatially positioned in the direction of a recording object, in particular a patient.
  • the highest sterility requirements are known to exist in operating rooms. This means in particular that the personnel directly involved in the operation must not come into contact with non-sterile objects before and during the operation.
  • the surgeon uses technical aids, in particular electronic devices, that are not themselves autoclavable, that is to say completely sterilizable, complicated remote control mechanisms have hitherto been required to ensure the sterility requirements described above, that is, the surgeon's absolute freedom from contact with non-sterile objects .

  • the device according to the invention it should in particular be possible to operate electrical devices safely even under clean room or sterility conditions. The technical as well as the cost to be undertaken for this should be as low as possible.
  • the device according to the invention for manual, contactless actuation of an electrical device has at least one transmitter unit and one receiver unit, which are arranged next to one another in such a way that from the Transmitting pulses emerging from the transmitting unit can be reflected on an object spaced from the transmitting and receiving unit and that these transmitted pulses reflected on the object can be at least partially detected by the receiving unit.

  • the control processes relate to all those device functions that an operator actively operates in handling the device in order to operate it.

In such a case, care must be taken to ensure that the individual transmission units emit transmission pulses with different modulations.
  • a further measure to avoid such undesired triggering of functions relates to the possibility of providing a reception characteristic that is as sluggish as possible within the receiving unit, which ensures that brief object movements within the reception area do not trigger any function activations.

Abstract

L'invention concerne un dispositif pour l'actionnement manuel sans contact d'un appareil électrique sur lequel au moins une unité émettrice et une unité réceptrice sont placées à côté l'une de l'autre de sorte que des impulsions d'émission sortant de l'unité émettrice peuvent être réfléchies sur un objet situé à distance de l'unité émettrice et de l'unité réceptrice et que les impulsions d'émission réfléchies sur l'objet peuvent être au moins partiellement détectées par l'unité réceptrice, l'unité réceptrice étant raccordée à un circuit électrique activable par la détection des impulsions d'émission réfléchies dans le but de provoquer une manoeuvre au niveau de l'appareil. Un tel dispositif est utilisable de préférence dans des conditions ambiantes stériles, et sert donc notamment à l'actionnement manuel sans contact d'appareils électriques non stériles se trouvant à l'intérieur d'une salle d'opération.
