Abstract
The invention refers to a sensor arrangement for weight and/or movement sensing in a bed and uses thereof, to a bed and to a method of sensing weight and/or movement of a user in a bed. For the sensing of weight, activity and/or cardiopulmonary performance in a bed, force sensors (6) integrated between a bedframe (2) and a mattress frame (3) are used. The sensors are designed in a way that they can be positioned between the mattress frame and the bedframe without significantly enhancing the height of a mattress bearing surface. Thus, the integration into any bed with bedframe can be easily realized. The measurements do not require any user interaction or even direct contact between user and sensor.
Claims12
Sensor arrangement for weight and/or movement sensing in a bed, comprising a structure (1) attachable between a bedframe (2) and a mattress frame (3), the structure comprising a first sensor support (4) and a second sensor support (5), the first sensor support and the second sensor support extending in a space below the mattress frame (3), where in the space, the mattress frame is unsupported by the bedframe (2), and wherein at least one sensor (6) is arranged between the first sensor support (4) and the second sensor support (5).
Method of sensing weight and/or movement of a user in a bed, comprising the steps of
- transferring forces exerted between a bedframe (2) and a mattress frame (3) of the bed to a space below the mattress frame, where in the space, the mattress frame is unsupported by the bedframe and
- measuring the forces by at least one sensor in the space below the mattress frame.
