## Abstract

A patient transfer device for transferring a patient placed on a movable sheet from a first surface to a receiving surface, said patient transfer device including first and second laterally spaced apart retractable pulling members, at least one motor operatively connected to the pulling members so as to allow retraction of the pulling members by means of the motor, where the pulling members comprise a bobbin and a wire, where the patient transfer device comprises an absorbent member removably arranged around the wire. Accordingly, the wire may be cleaned in a reliable manner.

## Claims

### Claim 1

A patient transfer device for transferring a patient placed on a movable sheet from a first surface to a receiving surface, said patient transfer device comprising: a first and second laterally spaced apart pulling members, where a pulling member comprises a bobbin and a retractable wire, at least one motor operatively and mechanically connected to the bobbin of the pulling members so as to allow retraction of the wire means of the motor and a sheet holding arrangement that is connected or connectable to the wire of the pulling members and that is configured to attach and hold the sheet in place in relation to the sheet holding arrangement so as to allow transfer of the patient by arranging the patient transfer device and the first surface on opposite sides of the receiving surface and simultaneously retracting the wires that the sheet, and thereby also the patient, is pulled from the first surface to the receiving surface, wherein the patient transfer device comprises an absorbent member removably arranged around the wire; wherein the bobbin with the wire is removable from the patient transfer device; wherein the patient transfer device comprises a pad arranged on the patient transfer device where the pad is adapted to bear on a frame of the receiving surface, where the pad comprises a hole adapted to hold the absorbent member and/or insert.

### Claim 2 (depends on 1)

The patient transfer device according to claim 1, wherein the absorbent member is cylindrical and longitudinal and is provided with a slit extending from an outer surface to the center of the absorbent member, such that the absorbent member may be replaced without removing the wire.

### Claim 3 (depends on 1)

The patient transfer device according to claim 1, wherein the patient transfer device comprises an insert adapted to hold the absorbent member.

### Claim 4 (depends on 3)

The patient transfer device according to claim 3, wherein the insert comprises attachment means adapted to attach the insert to the patient transfer device.

### Claim 5 (depends on 3)

The patient transfer device according to claim 3, wherein the insert is provided with a slit, such that the insert may be replaced without removing the wire.

### Claim 6 (depends on 1)

The patient transfer device according to claim 1, wherein the pad is provided with a slit such that the pad may be replaced without removing the wire.

### Claim 7 (depends on 1)

The patient transfer device according to claim 1, wherein the bobbin is symmetrical such that the bobbin can be mounted on either side of the motor.

### Claim 8 (depends on 1)

The patient transfer device according to claim 1, wherein the patient transfer device comprises an outer casing arranged to cover the bobbin and the motor.

### Claim 9 (depends on 8)

The patient transfer device according to claim 8, wherein the patient transfer device comprises an inner casing arranged to cover the motor.
