    • A method of pressure regulation and a ventilator are provided. The ventilator includes a positive relative pressure gas supply, a negative relative pressure gas supply, and a diverter valve. The diverter valve includes a positive pressure port connected to the positive relative pressure gas supply, a negative pressure port connected to the negative relative pressure gas supply, and a gas supply port communicating with a gas delivery device. The ventilator preferably further includes a feedback sensor that detects a gas supply difference between a gas supply and a predetermined gas supply and generates a feedback signal that is substantially related to the gas supply difference. The ventilator preferably further includes a diverter valve actuator communicating with the diverter valve and operating the diverter valve to communicate the positive relative pressure gas supply and the negative relative pressure gas supply to the gas supply port of the diverter valve based upon the feedback signal.

    • A forced air warming unit has a casing that encloses a scroll housing with a curved inside surface. A blower is disposed in the scroll housing inside the curved surface. Inlet and outlet openings are provided in the casing. A circuit board is mounted in the casing, against the scroll housing so that the blower is enclosed in space between the scroll housing and the circuit board. At least one opening is provided through the circuit board into the space in which the blower is disposed. A tapered, elongate, arcuate heater plate is disposed in the scroll housing between the circuit board and the blower, with a relatively wide end near the outlet opening and a second, relatively narrower end near the curved inside surface. Air is conducted in response to operation of the blower through the inlet opening, along a first side of the circuit board through the one or more openings in the circuit board into the scroll housing. Air is also conducted in response to operation of the blower along a second side of the circuit board which faces the scroll housing, through air passages in the circuit board to and along the first side through the one or more openings, into the scroll housing. Air entering the scroll housing in response to operation of the blower is accelerated by the blower along the curved inside surface while being heated in response to operation of the heater plate. Heated, pressurized air exits the forced air warming unit through the outlet opening. Provision is made for connecting an air hose to the outlet opening for conducting the pressurized, heated air to a pneumatic, convective device.

    • A respirator mask includes an inner plenum with a gas inlet and a manifold adapted to fit under the nose of a wearer, a pair of nasal inserts projecting from the manifold to define primary seals with the nasal passages of the wearer, an outer plenum adapted to surround at least the nose of the wearer, a secondary seal mounted on an outer edge of the outer plenum and adapted to contact the face of the wearer around the nose in air tight relation, and at least one opening formed in the inner plenum to permit gas to flow into the outer plenum. By pressurizing the outer plenum, the mask decreases the pressure differential between the interior of the mask and the outside atmosphere to reduce the gas flow rate out of the mask in the event of a leak. Diversion of gas into the outer plenum also allows use of an inflatable secondary seal to maintain air-tight contact with the face of the user.
    • 呼吸面罩包括具有气体入口的内部增压室和适于装配在穿着者的鼻子下面的歧管;一对鼻插入件,其从所述歧管突出以限定所述穿用者的鼻通道的主要密封;外部增压室, 至少包围穿戴者的鼻子,二次密封件,其安装在外部增压室的外边缘上并适于以气密关系的方式接触穿过鼻子的穿着者的面部,以及形成在内部通风室中的至少一个开口以允许 气体流入外部通风室。 通过对外部增压室进行加压,掩模减小了掩模内部和外部气氛之间的压力差,以在泄漏的情况下将气体流速降低到掩模外。 将气体引入外部通风室还允许使用可充气的二次密封件来保持与使用者的面部的气密接触。
