A person lift system includes a motor and a sling bar coupled to the motor. The sling bar includes a first attachment hook at a first end region of the sling bar and a second attachment hook at a second end region of the sling bar. A patient-lift sling includes a sling body and a plurality of attachment straps coupled to the sling body. Each of the plurality of attachment straps is configured to attach to one of the plurality of attachment hooks.

A person lifting apparatus includes a strap movement system. The person lifting device includes a housing and a lifting strap feeding device located in the housing. The lifting strap feeding device includes a motor connected to a drum and a lifting strap wound on the drum. A sensor provides a signal indicative of force on the lifting strap. A controller receives the signal from the sensor. The controller controls operation of the motor based on the signal. A user input is used to place the strap movement system in a fast mode during which the controller speeds up operation of the motor from a normal operating speed.

Support harnesses and systems and kits including the same are disclosed. A support harness includes a plurality of straps arranged such that a first strap, a second strap, and a third strap are spaced apart from one another, and the third strap extends between the first strap and the second strap. The support harness further includes a first connection piece extending between a proximal end of the first strap and a proximal end of the third strap and a second connection piece extending between a proximal end of the second strap and the proximal end of the third strap. The first strap, the second strap, and the third strap are each positionable around a horizontally positioned subject by wrapping the respective distal ends around a body part of the horizontally positioned subject and coupling the distal ends to the respective portions.

A multi-link device includes a load tension pin including a sensor configured to measure tension applied to the load tension pin, network interface hardware, one or more processors, and one or more memory modules storing computer readable and executable instructions which, when executed by the one or more processors, cause the multi-link device to: determine whether the tension measured by the load tension pin exceeds a threshold value; and transmit, by the network interface hardware, load event data to a receiver in response to determination that the tension exceeds the threshold value.

Support straps having features to aid in positioning and rotating a horizontally laying subject on a support surface, systems including the support straps, and kits of parts including the support straps are described herein. A support strap includes a body having first and second ends spaced a distance apart, at least one first loop extending from the first end, at least one second loop extending from the second end, and indicia on the body, the first loop, and/or the second loop. The indicia indicates an arrangement of the support strap with respect to the subject such that a centerline of the subject is not aligned with a true line of symmetry of the support strap when the first loop is coupled to a first end of a sling bar and the second loop is coupled to a second end of the sling bar.

Sling bars, lift systems, and methods of attaching a subject sling to a sling bar are disclosed. A sling bar includes a bar extending in a longitudinal direction, a protrusion extending from an upper part of the bar, a sling attachment portion extending to define a receiving aperture, a terminus of the sling attachment portion facing the protrusion, defining an opening into the receiving aperture, the protrusion defining an undercut portion of the receiving aperture, a retention latch pivotally coupled to the protrusion and defining an engagement face that selectively interfaces with a stop surface at the terminus in a closed position to cover the opening, the retention latch being constrained to pivot to an open position whereby the retention latch ceases to interface with the stop surface at the terminus, and a biasing mechanism coupled to the retention latch to force the retention latch toward the closed position.

A transfer assembly for a hoist unit for a patient includes a motor base, a first frame secured to the motor base for rotation about a pitch axis. The first frame includes one or more first suspension wheels rotatably affixed thereto for rotation about a laterally extending axis. The transfer assembly also includes a second frame secured to the first frame for rotation about a yaw axis. The second frame includes one or more second suspension wheels each of which is rotatably affixed thereto for rotation about a laterally extending axis. The transfer assembly also includes a drive wheel assembly rotatably mounted on the motor base for rotation about a laterally extending drive wheel axis. The transfer assembly also includes a motor assembly secured to the motor base and operatively connected to the drive wheel assembly such that operation of the motor rotates the drive wheel assembly.

A multi-link device includes a load tension pin including a sensor configured to measure tension applied to the load tension pin, network interface hardware, one or more processors, and one or more memory modules storing computer readable and executable instructions which, when executed by the one or more processors, cause the multi-link device to: determine whether the tension measured by the load tension pin exceeds a threshold value; and transmit, by the network interface hardware, load event data to a receiver in response to determination that the tension exceeds the threshold value.

A method of rotating a subject includes arranging a lifting aid underneath the subject such that a midline of the subject is off center from a centerline of the lifting aid in a direction opposite of the rotation direction. The lifting aid includes a first loop extending in the rotation direction and a second loop extending in the opposite direction. The method further includes connecting the loops to a sling bar coupled to an overhead lift and directing the overhead lift to raise, where the subject rotates towards the direction of rotation due to the off center location of the subject. The method further includes repositioning the subject when the subject has rotated to a lateral recumbent position and directing the overhead lift to lower, thereby causing the subject to continue rotating.

An overhead lift system may include a motor and a lift strap connected to the motor. The motor raises and lowers the lift strap. A hand controller may be communicatively connected to the motor. The hand controller includes a force sensor associated with the body of the hand controller such that force applied to the body is detected with the force sensor. An orientation sensor may also be arranged within the body and determines an orientation of the hand controller. A control unit may be communicatively connected with the motor, the force sensor, and the orientation sensor. The control unit detects a force applied to the hand controller with the force sensor, determines a direction of motion of the hand controller with the orientation sensor, and provides a signal to the motor to raise or lower the lift strap based on the force and orientation of the hand controller.
