摘要:
A respiratory mask (10) that comprises a mask body (12) and a harness (21) that includes a carriage (22) and a strap (24). The mask body (12) lacks a rigid insert, is non-elastomeric, and is adapted for fitting over a person's nose and mouth. The mask body (12) has a nose portion (14), a chin portion (16), first and second cheek portions (18 and 20), and an axis (32) that extends from the nose portion (14) to the chin portion (16). The mask body (12) is constructed to deform such that the first and second cheek portions (18 and 20) move towards each other about the axis (32). The carriage (22) is joined to the mask body (12), and the strap (24) is joined to the carriage (22) for supporting the mask body (12) over a person's nose and mouth. When tension is applied to the strap (24) and an opposing force acts at the nose and chin portions of the mask body, the first and second cheek portions (18, 20) exhibit movement about the axis (32) towards each other. The respirator mask is beneficial in that it is lightweight, easy to manufacture, and maintains a good fit to a person's face.

An anatomically fitted belt is used for carrying one or more waist-mounted respiratory protection components. The belt includes a main belt portion and a belt buckle portion. The main belt portion includes a back section, a left side section, a right side section, a left connective section between the back section and the left side section, and a right connective section between the back section and the right side section. The back section is wider than the other sections of the main belt portion. The main belt portion has a generally conical shape to be secured around a user's pelvic girdle and to align the respiratory component over the lumbar region of the user's spine to distribute a weight of the respiratory component. The belt buckle portion includes a right piece connected to the right side section of the main belt portion and a left piece connected to the left side section of the main belt portion.

An adaptor for delivering an aerosolized active agent to a patient with concomitant positive pressure ventilation includes an aerosol flow channel having an aerosol inlet port and a patient interface port, and defining an aerosol flow path from the aerosol inlet port to and through the patient interface port; and a ventilation gas flow channel in fluid communication with the aerosol flow channel and having a gas inlet port and a gas outlet port, and defining a ventilation gas flow path from the gas inlet port to and through the gas outlet port, wherein the ventilation gas flow path is at least partially offset from the aerosol flow path and at least partially encircles the aerosol flow path. Systems and methods for delivering an aerosolized active agent to a patient with concomitant positive pressure ventilation incorporate the adaptor.

A hands free pattern creating apparatus having a hands free securement component which can be utilized to secure a handheld pattern creating device relative a medium upon which the pattern is to be formed. The securement component can include a magnetic component configured to be secured to the hands free securement device such as magnetic tabs, a elongate member or a removable collar having magnetic or metallic components secured thereto. A pattern or design surface or mat having metallic or magnetic properties such that the magnetic component provides a desired amount of magnetic attraction when positioned on media positioned on the pattern mat to minimize movement of components pattern creating device during creation of the pattern on the media, but allowing the user to remove and/or reposition the pattern cutting device relative to the pattern mat once the pattern has been completed.

Method for making a filter cartridge that is suitable for attachment to a respiratory mask. The method comprises the steps of (a) providing a mass of filter material; (b) providing a filter cartridge housing that has an inlet and outlet and a sidewall that includes sheet material; and (c) thermoforming the sheet material of the housing sidewall around at least part of the mass of filter material to place the housing sidewall in direct contact with the mass of filter material to encapsulate the filter material so that fluid is prevented from passing through the filter cartridge from the inlet to the outlet without being filtered by the mass of filter material.
