EP0780111B1 - Control device for bed, especially for patient or nursing beds - Google Patents

Abstract

The operating apparatus (8) for an adjustable bed is supported by a carrier arm (9) attached to the backrest (5) so that it can be used by the patient for controlling the operating drives used to adjust the inclination of the mattress frame at either end and/or for operation of a communication device or a television receiver etc. The operating device may be secured to the end of the carrier arm via a ball- and-socket linkage allowing its position to be adjusted to suit the user, the carrier arm formed by a rigid tube with a number of flexible sections (10,12), providing further position adjustment.

US-A-3 757 363 relates to a clamping arrangement in cooperation with Hospital beds or other patient beds, which a holding device for Recording a communication device is used.

The invention has for its object a bed control device of the prerequisites To improve the genus so that even weak, old ones and disabled people use the control unit in any position of the bed frame can easily achieve that on the other hand, but also it is possible for any nursing staff to use this operating device trigger corresponding switching functions.

The object is achieved by the features set out in claim 1 .

In the invention, the bed control device is firmly connected to the backrest, so that there are all movements of the backrest and thus the bed frame, so angle and / or height adjustments, so that the person in bed does not turn around or is even more awkward Way to reach for controls on the control unit, which is even dangerous can be. Rather, the holding arm of the bed control device attached to the backrest so that the actual control panel of the control unit well brought into the field of vision of the person resting in bed can be so that they can be raised without raising their arms Trigger switching functions, for example moving the bed up or down and / or adjust the inclination, for example when driving in the sitting position Call system, can switch a TV set on and off or in the Is able to trigger an emergency signal.

But the caregiver, for example a nurse, can also do this Position the bed control unit on the holding arm in such a position that it is convenient the functions can be triggered.

However, it is also possible to trigger those triggered by the nurse or the like To put functions in a special footswitch, which in suitably electrically or electronically with that located on the holding arm HMI device is coupled.

According to claim 2 , the bed control device can be connected to the holding arm via a ball or via a ball joint.

In the drawing, the invention is applied to a bed 1 trained couch furniture illustrated. The bed 1 shows in the usual way Way bed heads 2 and 3 and a bed frame 4. The lying surface frame 4 can be raised and lowered via a linkage, not shown and to the headboard headboard 2 or to the headboard headboard 3 in each desired height also adjustable and in the desired Tilt and / or height position can be arranged lockable. Corresponding motor drives have also not been illustrated. These can be used as hydraulic motors or electrohydraulic adjustment motors, for example in the form of linear motors and / or alternately on both sides Piston-cylinder units to be acted upon by pressure medium be what is also not shown.

Also the individual power supply cables for supplying energy to the Drive motors have not been illustrated for simplicity since such motor drives for the height and / or inclination adjustment of Lying surface frame 4 belong to the prior art.

In the present case, the bed 1 shown was a so-called sectional frame bed formed with a foot, a heart part and a backrest 5.

On the bed frame 4 is a mattress pad and in the usual way Bedding available on which patient 6 rests.

Footrests 7 were shown as rigid supports with wooden cladding. Of course the reclining furniture is not limited to such constructions. Rather, suitable beds, for example sick beds, can be attached to this Also use the braked brakes that are usually available on sick beds Rollers are provided to move the bed from one to the other Transport other room more easily, especially to a disinfection center to bring.

With the backrest 5 is an overall designated by the reference numeral 8 Bed control device referred to, either on one or the other Side of the backrest 5, if necessary also arranged at the head end can be. In Fig. 1, the bed control device 8 was on the right side attached while using thin lines on the same bed control device 8 the left side was illustrated. In contrast, in the embodiment 2, the bed control device 8 only on the left side of the bed arranged on the backrest 5.

The bed control device 8 essentially has a holding arm 9 which in the illustrated embodiment essentially of two lengths consists of the various rigid longitudinal sections 10, 11 and 12, on which the tubular holding arm 9 is arranged to be kinked. In this way, the actual input panel or the control screen can be 13 in a functional position with respect to the patient 6 swivel and adjust. Otherwise, the actual control screen 13 to be pivotable about the longitudinal axis 14. For this purpose the relevant length section of the holding arm 9 and the associated end face the control screen 13 with a spur toothing, grid, ball joint or the like to be provided to the set pivot position fix.

At one end the holding arm 9 is provided with a tab 15 which has two holes 16 and 17 to insert through the screws, not shown are through which the tab 15 with the bottom of the Backrest 5 can be releasably attached. There are also clamps, knurled nuts, Plates or the like of the tab 15 can be assigned if this is advantageous appears. In this way, the bed control unit 8 can each in arrange in a convenient way on the backrest 5. As can be seen, pivots the bed control unit 8 in the height and / or inclination adjustment Backrest 5 accordingly with, so that its location in relation to the Patient 6 does not change and this always trigger the desired functions well can.

The input panel or the control screen 13 is in the form of symbols provided by pictograms 18. The length and width dimensions L and B are so large that even people with visual impairments have the symbolism 18 can read well. For example, the length L is 140 mm. The symbolism is Expediently kept in black and white, so that color impaired People who can easily read the pictograms 18.

With the reference numeral 19 is an electrical or electronic arrangement referred to, by which the bed control device 8 electrically via a cable 20 connected is. In addition, foot switches 21 and 22 are through a rod 23 coupled with each other. Another electrical cable is shown at 24, which is also coupled to the arrangement 19. This way too the nursing staff from one or the other long side of the bed 1 the trigger corresponding functions. The nursing staff can also do that Swing the bed control unit 8 towards you in order to use the symbols 18 trigger the functions of the patient bed 1, for example opening and closing the bed to lower and / or tilt it with respect to the horizontal to bring, for example, in a Trendelenburg position.

The in the summary, in the claims and in the description described features and can be seen from the drawing both individually and in any combination for the realization of the Invention to be essential.
