A patient safety shield, and its method of use, features a deflector shield that closes gaps between the bottom profile of safety eyewear worn by the patient and the patient's cheek area. The deflector shield, when positioned, oriented, and profiled across the bridge of the patients nose and under the patient's eyewear , deflects fine infectious and or injurious debris, which originates in the patient's oral cavity, from being ejected off moving parts of dental tools during a dental procedure. The deflection by the deflector shield prevents potentially infectious or injurious debris from reaching and harming the eyes of the patient that may enter through the bottom gaps.

A method includes positioning a patient on a surgical support structure having a fixture. The method includes attaching, to a portion of a body of the patient, a first adhesive layer on a widened pad end of a surgical restraint device. The method includes extending an elongate strap member of the surgical restraint device in a direction in which the portion of the body of the patient is to be moved relative to a remaining portion of the body using tension in the elongate strap member. The method includes attaching an attachment end of the elongate strap member to the fixture of the surgical patient support structure to maintain the moved portion of the body in tension, exposing a surgical site on the body.

A warming device including a heat generating element that contains a powder of an oxidizable metal, a powder of a carbon material, water, and a powder of a porous material other than the oxidizable metal and the carbon material. The heat generating element is a sheet material, and in the heat generating element, a ratio of the mass content of the water to the mass content of the powder of the oxidizable metal multiplied by one hundred [100 × (water / powder of oxidizable metal)] is from 30 to 270.

An ear-and-eye mask (10) is provided comprising a noise-attenuation-and-generation assembly (46) having a digital domain, the noise-attenuation-and-generation assembly comprising, in the digital domain, a noise cancelling-circuit (48) and a noise masking circuit (64), wherein the noise-cancelling circuit (48) receives an input from an audio capture device (56) thereof which communicates with the noise masking circuit (64). An adaptive spectral noise analyser and generator is provided which determines an unwanted remnant signal comprising the leftover unwanted frequency and/or volume after noise cancellation, and wherein the noise attenuation-and-generation assembly (46) then determines and generates a compensation frequency and/or volume for countering this unwanted remnant signal following noise attenuation for output by a speaker (36) through a stem (40) direct to the user's ears.

A personal entertainment respiratory apparatus provides air to a user to provide a fully immersive entertainment experience. The personal entertainment system may comprise a flow generator for providing the flow of air. A personal spatial respiratory interface may be coupled to the flow generator. The personal spatial respiratory interface may comprise an outlet for the flow generator. The personal spatial respiratory interface may further be configured to direct the flow of air within an ambient breathing proximity of a user. The personal entertainment respiratory apparatus may further comprise a controller and a sensory particle dispenser. The controller and sensory particle dispenser may be configured to selectively activate release of a sensory particle from the dispenser into the directed flow of air in response to an entertainment triggering signal.
