摘要： A CPAP system is described for improved respiratory therapy of patients. In particular a patient interface is disclosed with an outlet vent with lower noise levels and more diffused outlet flow over prior art outlet vents. The outlet vent includes a main vent which is diffused and muffled and a higher resistance vent provided in case the main vent is blocked. The outlet vent is removable for easy maintenance and provides indication to the user when maintenance is required. The outlet vent described may be used on nasal masks, mouthpieces and patient interfaces generally.

摘要： A device (8) for improving a user's breathing includes an oral appliance (10) and a connecting post (20) coupled to the oral appliance (10). The connecting post (20) has an arm (22) providing a standard interface to engage cooperatively shaped openings (40, 42) in other components (24, 26, 44, 60) each designed to improve the user's breathing in at least one respect. A CPAP interface (44) coupled to the arm (22) may deliver a gas to the user's nose to improve the user's breathing. A venting seal (24) coupled to the arm (22) may reduce venting of the gas from the user's mouth to further improve the user's breathing. The CPAP interface (44) may include a pair of nasal pillows (30) that seat within a portion of the user's nose to deliver the gas to the user. A pair of tubes (48) are coupled to the nasal pillows (30). A pair of joints (50) coupled to the tubes (48) allow the positions of the tubes (48) to be adjusted as appropriate to adjustably position the nasal pillows (30) within the user's nose.

摘要： A simple, lightweight, easily deployable mask designed for use in modern fires. The mask substantially covers a wearer's face and includes a peripheral adhesive seal for preventing contaminants from effecting the wearer's visual or respiratory systems. The peripheral seal preferably comprises an adhesive band employing the skin adhesive commonly used in surgical masks. The adhesive band provides for closed attachment of the mask to the brow, the temporal area, cheek, over the jaw and down under the chin. The mask is anchored firmly to the ears of the wearer by resilient straps. Thus attached, the mask seals the eyes, nasal passages and mouth from the toxic external environment. The mask includes an intermediate seal separating the mask into separate visual and respiratory portions. The mask further includes a particulate filter impregnated with MOLECULITE® and one, or more frangible vials filled with perfluorocarbon saturated with oxygen which combine to filter out particulates, absorb toxic chemicals and provide a source of oxygen to the wearer.
摘要翻译：一种简单，轻便，易于部署的面具，专为现代火灾而设计。面罩基本上覆盖佩戴者的脸部，并且包括用于防止污染物影响佩戴者的视觉或呼吸系统的周边粘合密封件。周边密封件优选地包括使用通常用于外科口罩的皮肤粘合剂的粘合带。粘合带提供了将面罩与眉毛，颞部区域，颊部，颌部以及下巴下方封闭连接。面罩通过弹性带牢固地固定在佩戴者的耳朵上。因此，面罩从有毒的外部环境中密封眼睛，鼻腔和口腔。掩模包括将掩模分离成单独的视觉和呼吸部分的中间密封件。掩模还包括用MOLECULITE浸渍的微粒过滤器和一个或多个易燃的小瓶，其填充有用氧饱和的全氟化碳，其结合以过滤掉颗粒，吸收有毒化学物质并向穿用者提供氧气源。

摘要： A supplemental gas assembly (10) such as used for aircraft crews is provided which includes a mask (12) adapted to fit over at least the nose and mouth of a wearer, together with a flexible, self-elongating hose assembly (14) and a stowage box (16) for receiving the mask (12) and hose assembly (14); the assembly (14) is designed so that when the mask (12) is pulled from the box (16), pressurized gas passing through the hose assembly (14) serves to inflate and axially expand the assembly (14) to a deployed length greater than the relaxed length thereof. The assembly (14) preferably includes an inflatable elastomeric inner tube (30) together with an exterior sheath (36) of woven or braided material which restricts radial expansion of the tube (30) while permitting axial expansion thereof. In preferred forms, the deployed length of the assembly (14) is up to three times greater than the relaxed length thereof.

摘要： A gas mask structure including a rear cup body, two cell seats and a front cup body. The rear cup body has an opening facing backward. A top side of front face of the rear cup body is formed with an inlet and a guide way downward extends from the inlet. An inclined outlet is formed on a bottom side of front face of the rear cup body. A check membrane is disposed on front side of the outlet. The cell seats are respectively disposed on two sides of the bottom of the rear cup body for receiving cells therein to provide power for a motor to drive a fan. The front cup body is fixedly disposed on lower side of the front end of the rear cup body. A filter body is positioned in a fixing seat of the front cup body. A cover body is screwed on the fixing seat to fix the filter body therein and tightly hold a second filter body in front of the filter body. An inner face of the fixing seat is formed with a through hole in which the motor and the fan are disposed. The fan serves to generate air flow which is filtered through the second filter body and the filter body and then conducted into the guide way of the rear cup body.

摘要： A lightweight, portable non-invasive device specifically designed to regulate and effectively equalize the pressure between the sinus cavities and middle ear, and the nasal cavity and nasopharynx. The relieving of the pressure within the sinus cavities in turn relieves pain normally associated with such a condition. The subject pressure equalizing assembly has a face mask having a seal disposed about the outer periphery thereof which is specifically dimensioned and configured to surround the nose and nostrils of the user in an outwardly spaced relation thereto. This seal effectively isolates the nasal cavity and nasopharynx when the user swallow, and defines direct fluid communication with a vacuum chamber and a pressure regulating assembly serving to create an initial negative pressure within the nasal cavity and nasopharynx. Fluid in the form of mucous, liquid and/or air is transferred from the sinus cavities which may define a zone of relative high pressure such that the pressure is effectively regulated between the sinus cavities, middle ear, nasal cavities and nasopharynx through the selective manipulation of the pressure regulating assembly thereby providing immediate relief from sinus pain while helping to relieve middle ear pressure and associated symptoms.

摘要： A pouch is provided for the blower unit of a powered air-purifying respirator system, to isolate the blower unit from hazardous material such as potentially-explosive dust or gas. The pouch has an opening at one end through which the blower unit can be inserted into the pouch, and is shaped at the other end to receive the blower unit. It also has air inlet openings positioned to register with air inlets of the blower and permit the connection of the filter cartridges thereto, and an air outlet opening positioned to register with the air outlet of the blower unit and permit the connection thereto of a breathing tube of the respirator system. When the blower unit is inside the pouch, seals at the pouch openings inhibit or prevent particulate or gaseous material from entering the pouch through the openings.

摘要： A connector includes a mask end for connecting with the interior of a respiratory mask, a supply conduit end, and a gas washout vent passage having an inlet adjacent to, or forming part of, the mask end in fluid communication with the interior of the respiratory mask and an outlet in fluid communication with atmosphere. The vent outlet of the vent passage is disposed on the side of the connector remote from the mask end. A respiratory mask includes a mask shell, a mask inlet for connecting with the outlet of a breathable gas supply conduit, and a gas washout vent passage. A vent outlet is disposed on the side of the mask remote from the mask interior and is adapted to direct the washout gas in a direction substantially parallel to the longitudinal axis of the mask inlet and away from the mask inlet.
