Abstract

An electric actuator system for hospital and care beds (1, 20) for adjusting e.g. the lying surface of the bed (1, 20). The actuator system is connected to one or more light sources (19, 23, 24), which may be switched on if a change in the patient'"'"'s movement pattern and/or position in the bed (1, 20) is registered. The electric actuator system may thus help the patient navigate around the room.

Claims

1. An electric actuator system for hospital and care beds (1,20) comprising at least one linear actuator (9,10,13,14,21,22) for adjusting the bed (1,20), a control box (15) and at least one control unit (17,18), where the linear actuator (9,10,13,14,21,22) and the control unit are connected to the control box (15) and where the linear actuator (9,10,13,14,21,22) comprises means for registering a force on the linear actuator (9,10,13,14,21,22) and relative changes therein, and one or more light sources (19,23,24) which may be activated if one or more changes in the force on the linear actuator (9,10,13,14,21,22) is registered.

2. The electric actuator system according to claim 1, including means for wireless connection between said control box and said one or more light sources (19,23,24).

3. The electric actuator system according to claim 1, comprising a light source (19,23,24) which can be located on a bed (1,20).

4. The electric actuator system according to claim 1, wherein the control box (15) comprises at least a part of the control for the actuator system.

5. The electric actuator system according to claim 1, wherein the control box (15) comprises a mains based power supply.

6. The electric actuator system according to claim 1, wherein the control box (15) comprises a rechargeable battery pack.

7. The electric actuator system according to claim 1, wherein said means for registering the force on the linear actuator (9,10,13,14,21,22) comprises a load cell.

8. The electric actuator system according to claim 1, including a junction box 16.

9. The electric actuator system according to claim 8, wherein the junction box comprises a light source (19).

10. A hospital or care bed comprising an electric actuator system according to claim 1.
