Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus includes a support structure and a drive wheel assembly having at least one drive wheel, a powered drive system coupled to the at least one drive wheel, and at least two user input devices. The apparatus also includes a controller coupled to the powered drive system and user input devices configured to determine which one of the user input devices is active and operable to cause the powered drive system to rotate the drive wheel and to maintain the other user input device as inactive, or passive.

Abstract: A patient transport apparatus transports a patient over a floor surface. The patient transport apparatus comprises a support structure and support wheels coupled to the support structure. An auxiliary wheel is coupled to the support structure to influence motion of the patient transport apparatus over the floor surface to assist users. An actuator is operatively coupled to the auxiliary wheel and operable to move the auxiliary wheel relative to the support structure from a retracted position to a deployed position. A user interface sensor is operatively connected to the actuator and configured to generate signals responsive to the user touching the user interface. A controller is operatively coupled to the user interface sensor and the actuator to operate the actuator in response to detection of signals.

Abstract: An applicator having a body configured to house a fluid, an application member in selective fluid communication with the body, and a time-indicating device, wherein the time-indicating device includes a capillary component having a fluid path, wherein the time-indicating device is configured such that fluid advancement along the fluid path directly or indirectly provides at least a first observable signal, and wherein the first observable signal signifies a first certain application period.

Abstract: Medical devices configured to provide a controllable release of a drug, particularly for use in pleural effusion therapy. The medical devices comprise a component including a carrier-drug complex, wherein the carrier-drug complex comprises one or more molecules of a drug reversibly bound to a porous carrier. The present disclosure also relates to methods of making the carrier-drug complexes and medical devices described herein.

Abstract: An optical polymeric material that can substantially block the transmission of ultraviolet light as well as selected portion of violet light. The polymeric material will include monomeric units of one or more lens monomers, and monomeric units of a monomer of formula (I).
