A wheel cover assembly includes a wheel housing configured to house a wheel mechanism; a neck portion upwardly extending from the wheel housing, wherein the neck portion includes a hollow channel that extends into the wheel housing; a pair of clips configured on the neck portion; and a lip portion extending from a lower portion of the wheel housing. The wheel housing includes a first half wheel cover; a second half wheel cover; and a plurality of tabs connected to each of the first half wheel cover and the second half wheel cover, wherein the plurality of tabs selectively align together upon connection of the first half wheel cover with the second half wheel cover.

A walking aid device includes a support body inclusive of a plurality of support elements extending toward the ground. Each support element is coupled to a caster and a brake unit. Each brake unit has a clutching surface. The clutching surface controllably clutches a wheel of the caster or the ground to thereby generate friction for stopping the walking aid device.

A mobile X-ray imaging system includes an X-ray radiation source. The mobile X-ray imaging system also includes an X-ray detector. The mobile X-ray imaging system further includes a C-arm having the X-ray radiation source disposed on a first end and the X-ray detector disposed on a second end opposite the first end. The mobile X-ray imaging system further includes a C-arm rotation device coupled to the C-arm and configured to rotate the C-arm in an orbital direction relative to the C-arm rotation device. The mobile X-ray imaging system further includes a mobile base coupled to the C-arm rotation device, wherein the mobile base is configured to move the mobile X-ray imaging system, and wherein the mobile base includes a damping system configured to dampen vibrations that occur when the C-arm deaccelerates to a stop during rotational movement of the C-arm in a single or combined direction.

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.

The present disclosure relates to a wheelchair comprising a wheel axle (1) having a wheel axle end portion (9) and hub (3) having a central through-opening (11) arranged to receive the wheel axle end portion (9). The wheel axle end portion (9) has an external surface having three chamfered faces (3a, 3b), each chamfered face (3a, 3b) defining a planar surface, and the hub (3) has inner walls (13a, 13b, 13c) defining the central through-opening (11). The inner walls (13a, 13b, 13c) are arranged to engage with the chamfered faces (3a, 3b) of the wheel axle end portion (9) to prevent relative rotation between the hub (3) and the wheel axle (1).

Devices, assemblies, systems, and methods are disclosed for stabilizing a cart. An example cart is a surgical cart having a robotic arm thereon. A stabilizer system may be part of or used with the cart to stabilize the cart at a location. The stabilizer system may include a stabilizer and an actuator. The stabilizer may have a foot and a biaser configured to bias the foot to a retracted position and contribute to an amount of force applied to a floor supporting the cart when the foot is in a deployed position. The actuator acts on the stabilizer to overcome a bias force biasing the stabilizer to the retracted position and cause feet of the stabilizer to contact the floor. Once the feet of the stabilizer contact the floor, a spring of the biaser causes the foot to apply a predetermined force amount to the floor.

A mobile X-ray imaging system includes an X-ray radiation source. The mobile X-ray imaging system also includes an X-ray detector. The mobile X-ray imaging system further includes a C-arm having the X-ray radiation source disposed on a first end and the X-ray detector disposed on a second end opposite the first end. The mobile X-ray imaging system further includes a C-arm rotation device coupled to the C-arm and configured to rotate the C-arm in an orbital direction relative to the C-arm rotation device. The mobile X-ray imaging system further includes a mobile base coupled to the C-arm rotation device, wherein the mobile base is configured to move the mobile X-ray imaging system, and wherein the mobile base includes a damping system configured to dampen vibrations that occur when the C-arm deaccelerates to a stop during rotational movement of the C-arm in a single or combined direction.
