The present invention relates to a motorized patient transfer device used for transferring bedridden patients. The device is primarily comprised of a base with at least one wheel, at least one tower, at least one tower covering, at least one support arm, at least one seat, at least one footrest, and at least one motor. The support arm, footrest, and seat can be positioned over or near a hospital bed such that a bedridden patient can then be transferred to the seat in a seated position. Then, the device can be rotated from over and/or away from the bed to easily transfer the patient to a chair or other location.

A stander device with improvements to facilitate and/or make more convenient the adjustment and/or repositioning of various elements of the stander device for sizing and comfort of a patient/user, as well as making the folding, storage, and transportation thereof more convenient.

Disclosed is a carrying module detachably provided on a host module. The carrying module comprises two mounting bases, two guardrails, two bearing plates, and a backrest assembly. The two guardrails are respectively connected and locked to the mounting bases by means of a first coupling device. The two bearing plates are respectively rotatably mounted at the bottoms of the two guardrails by a second coupling device. When being lifted upwards, the bearing plates are close to the guardrails, and when being horizontally placed, the bearing plates can be used for bearing weight. The backrest assembly is detachably connected and locked to the two guardrails by means of a third coupling device. The host module comprises a host body and a displacement module, which can be combined with a plurality of nursing modules to forma nursing machine, and can also be added with a push module to form a displacement machine.

A medical lift-assistance device including a bracket, a variable assist mechanism, a lifting arm, and a pad sub-assembly. The variable assist mechanism has a strut attached to the bracket, a height-adjustment feature, a first gear, a first axle, a first rotational axis extending along the first axle, a first rotational direction, a second gear, a second axle, a second rotational axis extending along the second axle, and a second rotational direction. The first gear is rotatably attached to the first axle and the second gear is rotatably attached to the second axle and engages the first gear. The strut applies a force to the height-adjustment feature capable of causing the first gear to rotate in the first rotational direction and the second gear and the lifting arm to rotate in the second rotational direction.
