Abstract

A transfer device has a carriage supported on a base, movable between a home position and an extended position. A table assembly includes a lower table fixed to the carriage and an upper table coupled to the lower table, movable between a downward position in forcible contact with the lower table and an upward position having no contact with the lower table. The table assembly moves toward the extended position with the tables in forcible contact to place the table assembly underneath the object to be transferred while keeping the base stationary. The plates are separated to lift the object on the upper table while the lower table remains resting upon the support surface. The table assembly returns to the home position while supporting the object on the upper table and keeping the upper and lower tables separated. The device may operate in a bidirectional manner.

Abstract

A table assembly for a patient transfer device has an upper table with side plates that are differentially extended at the ends, and valve control for pneumatic tubing integrated with retraction of the side plates. During patient delivery only the delivery side plate is raised, to avoid catching linens in the nip formed between upper and lower belts. A slide assembly supporting the table assembly includes a fixed plate, an intermediate plate, and a full-motion plate which extend by means of rack-and-pinion drives. Each plate is symmetrical, and pinions are symmetrically located on opposite sides of the fixed or intermediate plate to allow hyperextension to either the left or right. Improved steerage for the device is provided by two centerline wheels which counter-rotate from a straight position to a turning position and further to a lateral position wherein the wheels are orthogonal to the longitudinal centerline of the device.

Abstract

A patient transfer device includes a table assembly having upper and lower tables with counter-rotating upper and lower belts. Means are provided to move the table assembly toward an extended position with the upper belt moving at a rotational speed which is greater than a translational speed of the table assembly. Faster movement of the upper belt may be in response to a determination that the patient has a characteristic whose value is within a predetermined range. The patient characteristic may be patient weight, e.g., with the predetermined range being less than 250 pounds. In the illustrative implementation a patient transfer device of the present invention includes a control system having a keyboard for receiving user input indicating that the upper belt should be moved faster, and control logic responsive to the user input which controls speeds of motors that independently drive the upper belt and the table assembly.

Abstract

A disposable comfort sheet has a waterproof layer and an absorbent layer, with adhesive strips applied to the waterproof layer along side edges. The sheet is adapted for use with a patient transfer device having upper and lower counter-rotating belts, and protects the upper belt against contamination. The patient transfer device may have registration marks for installation of the sheet, and indicator marks can be printed at predetermined locations on the waterproof layer for alignment with the registration marks. The sheet may include various means for indicating prior use by a patient, such as an ink pattern made of a heat-sensitive or moisture-sensitive ink. The sheet may further include a peel-away layer releasably bonded to the absorbent layer, with additional longitudinal adhesive strips applied to the side edges of the peel-away layer. The peel-away layer protects the lower belt against contamination from the sheet after a patient is delivered.

Abstract

A table assembly for a patient transfer device has upper and lower tables surrounded by belts which counter-rotate as the table assembly moves between a patient and a supporting surface such as a bed. The table assembly includes integrated means for laterally retracting side plates of the upper table while adjusting incident angles of the side plates and vertically separating the upper table from the lower table. Guide slots in end plates fixed to a slide assembly retain positioning posts attached to ends of the side plates. The slots are inclined upwardly toward a centerline of the table assembly at different angles. A crank moves the side plates using a rotating disk attached to a central frame of the upper table and linkage arms with one end pivotally attached to a peripheral region of the disk and another end pivotally attached to one of the positioning posts.

Abstract

A patient transfer device has four casters and two counter-rotating steering wheels. The steering wheels provide a turning path whose center of curvature lies along a transverse centerline of the device. A foot pedal selectively lifts the steering wheels off the floor or brakes them. Another foot pedal at a back end of the device can lock the casters at the front end in a straight direction. The transfer table of the device may be inclined either longitudinally or transversely, and has an upper table whose edge rollers retract to introduce slack in the upper belt so that an air mattress can be inflated. The upper belt selectively disengages from the lower belt using movable, pneumatically-actuated pinch rollers. The outer surface of the upper belt is rough while the outer surface of the lower belt is smooth. The belts are constructed of a material which includes an antimicrobial agent.
