Abstract
A patient handling apparatus comprising a base with a frame and a patient support device. The patient handling apparatus further comprises a weighing arrangement for weighing a patient supported by the patient support device, said weighing arrangement comprising a sub frame and a plurality of load sensors. The sub frame is arranged on the load sensors, said load sensors defining a weighing area, whereby the patient support device is mounted to the frame such that a central point of a seat support portion of the patient support device is positioned outside the weighing area in at least one position of the patient support device.
Claims13
A patient handling apparatus, comprising:
- a base with a frame;
- a patient support device mounted to the frame;
- a weighing arrangement for weighing a patient supported by the patient support device,
- wherein the weighing arrangement includes a sub frame and a plurality of load sensors, the sub frame being connected to the base by the load sensors,
- wherein at least one of the load sensors is mounted to the base by means of a load sensor fastening arrangement,
- wherein the load sensor fastening arrangement includes:
- a fastening element adjustable along a tensioning axis for setting a tension between the load sensor and the base, and
- supporting means, the supporting means comprising a support element and a support member, wherein the support element or the support member has a bowl-shaped surface and the other of the support element, and the support member has a dome shaped surface,
- wherein a curvature of the bowl-shaped surface is arranged to engage a curvature of the dome shaped surface when the fastening element is adjusted for increasing the tension between the load sensor and the base.
A method for balancing a weighing arrangement of a patient handling apparatus comprising a base with a frame and a patient support device, the weighing arrangement comprising a sub frame and a plurality of load sensors, the method comprising:
- obtaining sensor signals from said load sensors and adjusting adjustable fixating means to adjust the fixation of the load sensors based on said sensor signals.
