Abstract
A patient handling apparatus (10) comprising a base (30) with a frame (31) and a patient support device (20). The patient handling apparatus (10) further comprises a weighing arrangement (90) for weighing a patient supported by the patient support device (20), said weighing arrangement (90) comprising a sub frame (91) and a plurality of load sensors (95, 96, 97). The sub frame (91) is arranged on the load sensors (95, 96, 97), said load sensors (95, 96, 97) defining a weighing area (S), whereby the patient support device (20) is mounted to the frame (31) such that a central point (C) of a seat support portion (21) of the patient support device (20) is positioned outside the weighting area (S) in at least one position of the patient support device (20).
Claims37
A patient handling apparatus comprising a base with a frame and a patient support device,
- wherein 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, said sub frame being arranged on the plurality of load sensors, the plurality of 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,
- wherein the sub frame is connected to the base by means of the plurality of load sensors,
- wherein the plurality of load sensors include a first load sensor, a second load sensor, and a third load sensor,
- wherein the sub frame is arranged on the first load sensor, the second load sensor and the third load sensor, and
- wherein the first load sensor is arranged proximal to the frame and each of the second load sensor and the third load sensor is arranged distally to said frame at a distance from the first load sensor extending across the weighing area.
A patient handling apparatus comprising a base with a frame and a patient support device,
- wherein 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, said sub frame being arranged on the plurality of load sensors, the plurality of 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,
- wherein the sub frame is connected to the base by means of the plurality of load sensors, and
- wherein at least one load sensor of the plurality of load sensors is mounted to the base by means of a load sensor fastening arrangement, the load sensor fastening arrangement comprising a fastening element adjustable along a tensioning axis for setting a tension between the at least one load sensor and the base, the load sensor fastening arrangement further comprising 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 at least one load sensor and the base.
