Abstract: A system and method is disclosed for performing diagnostics on patient devices (720). The patient devices (720) may include respiratory therapy devices that operate in accordance with instruction sets, such as software or firmware. A server (710) may maintain a database of diagnostic data (718) indicating faults in one or more of a plurality of patient devices (720). The server (710) may transmit this diagnostic data (718) to one or more computing devices (760), including identification of faults that have occurred. The server (710) may also transmit service data to the plurality of patient devices (720) in order to address the identified faults.

Abstract: A polymeric connector block for interconnecting a plurality of elongate tubular members into a structure has five-sided front and back sides with an orthogonal pattern of three parallel through-apertures therethrough. A fourth through-aperture passes from the left side to the right side, intersecting two of the parallel through-apertures at 90°. A non-through aperture passes from the top side and intersects the other of the parallel through-apertures at 90°. A sixth aperture extends into the block at an intermediate angle such as 45°. There are no apertures in the bottom side. Tubular members are insertable into the apertures and lockable therein by lockscrews. Tubular members may comprise tubing, pipe, electrical conduit and the like, and may include non-tubular materials such as solid rods. A wide range of structures may be created.
