Abstract

In a patient bed system, comprising a patient bed, a support column for supporting the bed and a trolley for transporting the bed, the bed having arranged on it first coupling elements (22) which are intended for selective connection to second or third coupling elements (24, 26) on the support column and on the trolley respectively, at least one of the coupling elements (24) located on the support-column side has provided on it at least one sensor (102) for sensing the position of a first coupling element (22) connected to the bed (18) in relation to the column-side coupling element (24), the sensor (102) taking effect when the bed is located on the trolley and the latter assumes in relation to the support column a specific position for transferring the bed onto the latter.

Claims

1. A patient bed system comprising a patient bed, a support column for supporting the bed and a trolley for transporting the bed, the bed having first coupling elements for selective connection to second or third coupling elements on the support column and on the trolley respectively, wherein at least one second coupling element located on the support column has at least one sensor for sensing misalignment of a first coupling element connected to the bed in relation to the column coupling element, the sensor taking effect when the bed is located on the trolley and the trolley assumes in relation to the support column a specific position for transferring the bed onto the support column.

2. The patient bed system according to claim 1, wherein the column coupling element is arranged on a column head adjustable via at least one actuating drive, and the sensor is connected to a control controlling the actuating drive of the column head.

3. A patient bed system comprising:

a patient bed having a first coupling element;

a support column for supporting the patient bed, the support column having a second coupling element;

a trolley for transporting the patient bed, the trolley having a third coupling element; and

a sensor attached to the second coupling element for sensing misalignment between the second coupling element and one of the first coupling element and the third coupling element.

4. The patient bed system of claim 3, wherein the sensor senses misalignment between the second coupling element and both the first coupling element and the third coupling element.

5. The patient bed system of claim 3, wherein the first coupling element is operable to selectively connect to the second coupling element and the third coupling element.

6. The patient bed system of claim 3, wherein the patient bed is located on the trolley, the trolley assumes a specific position in relation to the support column, and the sensor senses misalignment when transferring the patient bed from the trolley onto the support column.
