Abstract: Securement arrangements for use in securing a patient interface to the skin of a patient include a substrate material having a first surface and an adhesive material disposed on the first surface. The locations of the adhesive material are varied so as to minimize repetitious adherence of the adhesive material to the patient during repeated applications.

Abstract: A patient interface for use in delivering a flow of breathing gas to an airway of a patient. The patient interface includes a front portion and a rear portion coupled to the front portion. The front portion and the rear portion together define a cavity therebetween which is structured to receive the flow of breathing gas. The rear portion includes a support layer disposed directly adjacent the cavity, the support layer having a region having a plurality of first thru-holes structured to receive the flow of breathing gas from the cavity. The rear portion further includes a patient engaging layer structured to engage the patient at or about the airway of the patient, the patient engaging layer including at least a second thru-hole structured to receive the flow of breathing gas from the plurality of first thru-holes.

Abstract: An improved scraping edge for use on a plow blade employing at least one resilient scraping edge section for contact with a surface to be plowed and mounting holes to attach the scraping edge section to the plow blade.

Abstract: An improved material pusher or containment plow employing a floating vehicle-coupling system, a wear shoe, as well as a plurality of removable scraping edge sections.

Abstract: A snow or material pushing device for plowing a surface including a moldboard with a scraper blade, and having side plates attached at either end. The side plates further include skid or wear shoes pivotally or rotationally affixed to the side plates to remain in full contact with the surface, thereby reducing the need to adjust and replace the scraper blade and wear shoes.

Abstract: A material pushing apparatus is disclosed that has a central blade, at least one removable side plate attached to the central blade and a segmented scraping edge flexibly attached to the central blade along the bottom longitudinal edge of the blade. A position sensor is attached between the blade and the scraping edge and produces a position signal that is displayed to indicate the relative position between the blade and edge in order to characterize the amount of downward pressure applied to the scraping edge. Other aspects and features of the disclosed apparatus include a tilt sensor and display, and an improved coupler having shock-absorbing features and a cam-type clamping arrangement.
