Bed system for attachment to a hospital bed for turning a patient
There is provided a bed system for turning a patient, which system is simple to install on existing beds and which does not require any modification of the existing bed. The bed system has a base frame with attachment means for attachment of the bed system to an existing frame of a hospital bed. First and second sections with bed elements ensure proper support for the patient, and these sections are pivotally movable around an axis parallel with the length of the patient.
1. A bed system for turning a patient comprising:
a base frame;
a first section and a second section having bed elements for supporting the patient, said first section and said second section being pivotally movable around an axis parallel with a length of the bed system;
a first actuator and a second actuator connected to said first section and said second section thereby enabling movement of the sections, each of said first actuator and said second actuator being attached to the base frame;
control means for moving the first section and the second section independently, whereby an angle formed between said first section and said second section is controlled, said first section and said second section being rotatable through activation of the first actuator and the second actuator;
wherein the first section is attached to the base frame in a first pivot point, and the second section is attached to the base frame in a second pivot point enabling the sections to be rotatably moved, and wherein the first section is attached to the first actuator in a third pivot point, and the second section is attached to the second actuator in a fourth pivot point, wherein the third pivot point is located closer than the first pivot point to an edge of the first section facing the second section, and the fourth pivot point is located closer than the second pivot point to an edge of the second section facing the first section.
2. A bed system according to claim 1 , wherein the first actuator and the second actuator are linear actuators.
3. A bed system according to claim 1 , wherein the first pivot point and the third pivot point of the first section are located in an end of the first section.
4. A bed system according to claim 1 , wherein the second pivot point and the fourth pivot point of the second section are located in an end of the second section.
5. A bed system according to claim 1 , wherein the bed elements for supporting the patient are flat and quadratic to ensure even support.
6. A bed system according to claim 1 , wherein the bed elements for supporting the patient are provided with joints to allow bending of the bed elements.
7. A bed system according to claim 1 , wherein the first actuator is pivotally attached to the main frame in a fifth pivot point, and the second actuator is pivotally attached to the main frame in a sixth pivot point.
8. A bed system according to claim 1 , wherein the bed comprises a hospital bed.
9. A bed system according to claim 3 , wherein the first pivot point and the third pivot point of the first section are separated by 2-8 cm.
10. A bed system according to claim 4 , wherein the second pivot point and the fourth pivot point of the second section are separated by 2-8 cm.
