A wheel with high strength flexible spokes of the present invention, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

Cable protector devices, assemblies, and systems. The cable protection system may include a moveable system with wheels for moving the moveable system across a floor and a cable pusher attached to each of the wheels. Each cable pusher may include a frame with a pair of deflector legs configured to be positioned in front of and behind each wheel in close proximity to the floor. The cable pusher may be magnetically secured to the wheel, and the deflector legs may magnetically connect to the frame. As the wheels spin or rotate, the frame and deflector legs remain stationary, thereby pushing obstacles out of the way.

A medical apparatus according to an embodiment of the present invention includes: a medical device; and a plurality of caster units, disposed below the medical device, for supporting the medical device to be movable, wherein each of the plurality of caster units includes: a wheel part; and a shock absorbing member which is configured to support the wheel part and to absorb the shock applied to the wheel part, wherein the shock absorbing member includes: a wheel fixing member for fixing the wheel part; a body fixing member which surrounds the wheel fixing member and is fixed to the medical device; and a cushioning member which is disposed between the wheel fixing member and the body fixing member and is capable of elastic deformation, wherein the shock absorbing member includes: a first deforming part extending in the vertical direction; and a second deformation part extending, from an end of the first deformation part, in a direction different from the extending direction of the first deformation part.

The present invention provides a medical device comprising: a main body; and two or more fixed casters and at least one floating caster, which are connected to a bottom portion of said main body and support said main body, wherein said floating caster is capable of floating in the vertical direction relative to said main body.

A wheel with high strength flexible spokes of the present invention, including a rim and hub, and spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The spokes are also flexible and resilient such that they can bend while retaining their integrity and strength. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

Disclosed is an omni-directional electric medical care bed chair, including Mecanum wheels, rollover prevention wheels, a bottom support, motors, a controller, a push rod device, a bed chair device, a cervical traction device, a shoulder joint rehabilitation device and ankle joint rehabilitation devices, wherein the push rod device drives the bed chair device to move, and therefore mutual switching among states of sitting, lying and turning over of the bed chair device can be realized. In conjunction with a bed chair technology enabling lying and turning over, a Mecanum wheel technology and medical care rehabilitation equipment, the medical care bed chair has functions of sitting, lying and turning over, also has an omni-directional movement ability, and can assist a patient in body rehabilitation training.

A two-layer photo-responsive membrane including a polymer layer and a support layer, the polymer layer being disposed on a surface of the support layer. The polymer layer is formed of a graft copolymer that contains a hydrophobic backbone and multiple side chains, the side chains each consisting of repeat units that switch between a hydrophobic form and a hydrophilic form upon exposure to a light of a specific wavelength. The polymer layer has a molecular weight cut-off of 3,000 to 250,000 Daltons and a thickness of 50 nm to 10 ?m; and the support layer has a molecular weight cut-off of 50 to 250,000 Daltons. Also disclosed is a method of preparing this two-layer photo-responsive membrane.

The present invention relates to a multidirectional wheel, wherein the wheel has a wheel body rotatable about a wheel axle and having two half-shells and has a plurality of rotating bodies which are located at the outer periphery of the wheel body and via which the wheel can roll off, wherein at least one half-shell, and preferably both half-shells, has/have mounts in which end regions of the axles of the rotating bodies are received or which project into end regions of the axles of the rotating bodies, wherein the mounts of the half-shells are configured as continuously converging.

The present invention relates to a method of cleaning a multidirectional wheel, wherein the wheel has a wheel body which is rotatable about an axis and has a plurality of rotating bodies which are located at the outer periphery of the wheel body and which form the running surface of the wheel, wherein the wheel body has at least one hollow space which has at least one inlet opening and at least one outlet opening for a flushing fluid and wherein the method comprises the introduction of a flushing fluid through the inlet opening into the at least one hollow space of the wheel body and the washing around of the rotating body by the flushing fluid after the discharge of the flushing fluid from the outlet opening.

The invention provides a medical intravenous support apparatus that facilitates patient mobility while reducing the likelihood of an accidental fall. The design incorporates improved features for bag support, tube management, cord management, patient steadiness, user-friendly braking, and electric power supply.
