  • the invention is intended to create a functionally reliable and easy-to-clean bed operating device for the care sector.
  • a bed operating device for the care area is provided with a housing and with operating devices which are provided for the actuation of functional units and which are at least partially arranged on a wall of the housing, in which the wall of the housing is continuous at least in sections on its outside Has film, the housing is made watertight and the wall of the housing has at least one through opening which is closed with a water-impermeable but water vapor permeable membrane.
  • a bed control device is also provided according to the preamble of claim 7, in which a moisture sensor is arranged in the housing.
  • the waterproof housing enables the bed control unit to be easily disinfected by wiping it with a damp cloth or even immersing it, since moisture is prevented from penetrating into the housing.
  • a leak test can be carried out in a simple manner during manufacture by immersing the device.
  • the provision of a continuous film facilitates the watertight design of the housing in that additional seals can be saved, and thus increases its functional reliability, especially when the device is used for a long time. When using a transparent film, viewing windows for warning lights or displays can be produced in a simple manner and without the use of additional seals.
  • the bed control device can be designed as a handheld device connected to a wall station, which has several buttons for operating different functional units, such as call systems, telecommunication devices, radio and television sets.
  • the wall of the housing has at least one through opening, which is closed with a water-impermeable but water-vapor-permeable membrane, pressure equalization from the housing to the surroundings is possible despite the waterproof design of the housing. Water vapor can also escape from the housing, so that the housing can dry out. Sound transducers such as microphones and sound generators such as loudspeakers or hearing capsules can be arranged behind the membrane. In this way, the watertightness of the housing is ensured while the sound transducers and sound generators are fully functional.
  • a membrane made of a material that is on the market under the "Goretex" brand can be used as the membrane.
  • a moisture sensor is arranged in the housing. This enables permanent monitoring of the moisture in the housing, which further increases functional reliability.
  • the moisture sensor can be coupled to warning devices that a moisture signal, the exceeding of which could lead to the failure of the electronics in the housing, give a warning signal. An expected malfunction can thus be indicated and the device can be checked by the service personnel before an actual malfunction has occurred.
  • a leak test can be monitored using the moisture sensor at the end of the manufacturing process. If the device is faulty, the moisture sensor triggers a warning signal.
  • the film is at least partially provided with a plastic layer towards the interior of the housing.
  • This measure permits a mechanically stable design of the housing, so that no leaks at mechanically highly stressed points on the housing are to be feared.
  • Viewing windows for displays or warning lights or recesses for sound converters or sound generators and buttons can be provided in a simple manner by cutting out the plastic layer during manufacture.
  • the film can be printed on the inside before applying the plastic layer, so that decorations and symbols can be attached to be resistant to abrasion, cleaning agents and disinfectants.
  • the housing can be produced by deep-drawing the film and then injecting it with plastic.
  • the film advantageously has flexible sections, and the operating devices have buttons formed by the flexible sections of the film.
  • the keys are watertight due to their design, since there are no openings or sealing gaps between the housing and the keys.
  • Such buttons can be produced by simply omitting the back-injected plastic layer, wherein button symbols can be printed on the inside of the film before the back-injection.
  • the operating devices have a touch-sensitive keyboard.
  • a touch-sensitive keyboard has no moving parts and is therefore particularly suitable for the waterproof design of the bed control unit.
  • Such a keyboard can be arranged behind a film window and in front of a display device and can be part of an LCD display touch panel module, for example.
  • the keyboard is arranged behind a recessed section of the wall of the housing. Such an arrangement of the keyboard increases the functional reliability of the bed operating device by effectively protecting the keyboard from bumps or unintentional actuation.
  • the moisture sensor is formed from two comb-like, interconnected and spaced-apart conductor tracks on a circuit board.
  • Such a design allows the moisture sensor to be designed in a simple manner without significant additional costs, since the conductor tracks can be provided on a printed circuit board which is present anyway for accommodating the electronic components of the operating devices.
  • An analog input of a microcontroller or a simple comparator circuit can be used to evaluate the signal from the moisture sensor.
  • a further increase in functional reliability can be achieved by arranging a circuit for monitoring the supply voltage and a temperature sensor in the housing. In this way, a possible failure of the bed control unit due to overvoltage or undervoltage or due to overheating, for example due to excessive solar radiation, can be detected at an early stage. It is also advantageous if a receiving device for a transponder card is provided on the outside of the wall of the housing and can be coupled to transmitting and / or receiving devices in the housing. In this way, an identification card or payment card can be used on the hand-held device without the need to provide openings in the housing for such a card which impair the tightness.

  • a further advantageous embodiment provides that the outer wall of the housing has a through opening for receiving a socket and the rubber seal has a section surrounding the opening on the inside of the housing.
