A wheelchair includes a chair frame mechanism and two pedal mechanisms. The chair frame mechanism includes a frame body and two pedal-mounting rods. The pedal mechanisms are respectively mounted to the pedal-mounting rods. Each of the pedal mechanisms includes a pivot unit sleeved on the corresponding pedal-mounting rod and having has a guide groove, a positioning unit mounted to the corresponding pedal-mounting rod and engaging the guide groove, and a pedal unit mounted to the pivot unit.

Embodiments of the present disclosure include a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters that can selectively engage the arm assembly dependent on the position of the arm assembly and surface conditions of ground and can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A supporting structure includes two pairs of legs and four wheels each arranged at a lower end of a respective one of the legs. Each leg includes an upper segment and a lower segment, and optionally a retractable leg extension segment for contacting ground instead of the corresponding wheel. Such supporting structure is adapted for producing a lowering motion while keeping the legs crossed on both lateral sides. Such supporting structure may be adapted for assisting a disabled person in travelling on the ground, and also possibly in climbing stairs.

A standing wheelchair device includes a wheeled base for enabling the device to move on a supporting surface. A harness assembly includes a plurality of braces for attaching to parts of a body of a user of the device, at least some adjacent braces of being connected by joints. A lifting unit mounted on the base, supports a hip joint of the harness assembly, and is configured to raise or lower the hip joint. When the user is attached to the harness assembly and is in a sitting position, raising a height of the hip joint causes the user to assume a standing position. When the when the user is attached to the harness assembly and is in a standing position, lowering the hip joint causes the user to assume a sitting or reclining position.

The present disclosure relates to medical pads and methods of manufacturing medical pads.

The present disclosure includes a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

In accordance with one embodiment, an In situ Bed Chair (IBC) rotates back and forth and has elevating and lowering bed sections. In a second embodiment, the IBC converts from a flat bed into a chair or vice a versa such that a patient can remain in place during the conversion. The chair has wheels that enable easy transport of the patient to other locations.

This is directed to a smart ergonomic chair and mobility system. The system can be used as a working station, a working chair, a mobility device, a personal care device, or a combination thereof. The system is designed to provide ergonomic seating posture for a person who is seated on the chair. The system is also designed to reduce body stress by providing automatic movements of parts of the chair at predefined time points.

A soft-walled inflatable cradle (10) has a seat section (14), a back-support section (16), and a pair of opposed side panel sections (18, 20) extending between respective sides of the back-support and the seat. The cradle is positioned about a patient in an un-inflated condition and inflated to define a self-supporting seat structure. The cradle may be formed in at least two separable parts which can be positioned about a patient and connected together prior to inflation. The cradle may be used in co-operation with apparatus which include rollers over which the inflated cradle is moved. Methods of handling a patient using the cradle are also disclosed.

An operator chair comprises: a connection portion; a first parallel arm linkage to which an adjustable seat module is connected, the first parallel arm linkage being rotatably connected to the connection portion and to an armrest; a first actuator for driving the first parallel arm linkage between a first position and a second position, and thereby regulating a seat portion of the seat module between a first, substantially horizontal position corresponding to a sitting position of a user, and a second, at least partially vertical position corresponding to an at least partially standing position of the user, respectively; a second parallel arm linkage rotatably connected to the static fundament and to the connection portion; and a second actuator for driving the second parallel arm linkage so as to regulate at least the vertical position of the connection portion relative to the fundament.
