Abstract
A patient transfer device for moving a patient from a first surface to a receiving surface includes a retractable pulling wire, a motorized pulling arrangement, and a holder arrangement for holding a sheet or mattress. The holder arrangement has a holder element attached to a first end of the pulling wire. The pulling arrangement retracts the wire, moving the holder arrangement and holder element holding a sheet or mattress towards the pulling arrangement, thereby transferring the patient. A proximity sensor detects if the holder element reaches an end position near the pulling arrangement.
Claims23
A patient transfer device for transferring a patient placed on a sheet or a mattress from a first surface to a receiving surface, wherein the patient transfer device comprises:
- at least one retractable pulling wire;
- a pulling arrangement comprising a motor operatively connected to a pulling wire so as to allow retraction of the pulling wire by means of the motor;
- a holder arrangement for holding the sheet or the mattress when moving the sheet or the mattress and thereby transferring the patient placed on the sheet or the mattress;
- wherein the holder arrangement comprises a holder element to which a first end of the pulling wire is attached,
- wherein the pulling arrangement is configured to retract the pulling wire and thus move the holder arrangement and the holder element towards the pulling arrangement so as to, when the holder arrangement is arranged to hold the sheet or the mattress, move the sheet or the mattress towards the pulling arrangement and thereby transfer the patient placed on the sheet or the mattress from the first surface to the receiving surface,
- wherein the pulling arrangement is provided with a proximity sensor configured to detect whether the holder element has reached an end position at or close to the pulling arrangement
- characterized in
- that the proximity sensor is configured to sense presence or changes in an electromagnetic field or a beam of electromagnetic radiation,
- that the holder arrangement comprises a stop arrangement configured to hold the first end of the pulling wire in place with respect to the holder element, and wherein the holder element encapsulates the stop arrangement,
- that the holder element is provided with first, second and third apertures, and wherein the stop arrangement is arranged inside the holder element at the first aperture,
- that the pulling wire extends out from the holder element via the first aperture and back into the holder element via the second aperture so as to form a loop outside of the holder element between the first and second apertures,
- that the pulling wire extends out from the holder element via the third aperture and further towards the pulling arrangement,
- that the pulling wire is free to move in relation to the holder element between the second and third apertures so that the loop of the wire is tightened or decreased when pulling the pulling wire out from the third aperture and so that the loop of the pulling wire is loosened or increased when pulling the pulling wire out from the second aperture, and
- in that the holder element comprises a magnet wherein the magnet is provided with a through hole through which the pulling wire runs.

- that the pulling wire extends out from the holder element via the first aperture and back into the holder element via the second aperture so as to form a loop outside of the holder element between the first and second apertures,
- that the pulling wire extends out from the holder element via the third aperture and further towards the pulling arrangement,
- that the pulling wire is free to move in relation to the holder element between the second and third apertures so that the loop of the wire is tightened or decreased when pulling the pulling wire out from the third aperture and so that the loop of the pulling wire is loosened or increased when pulling the pulling wire out from the second aperture, and
- in that the holder element comprises a magnet or a piece of iron.
