Abstract: A latching mechanism for a pressure chamber for hypobaric use is disclosed. The mechanism includes one or more pin modules positioned on a periphery of a door of the pressure chamber, the door being adapted to open into the chamber and abut a frame of the pressure chamber when the door is in a closed position. The mechanism further includes an actuator for selectively engaging or disengaging the pin with the frame. The pin module may include a pin adapted to be selectively positioned in an engaged or a disengaged position. The pin in the engaged position extends from the door to the frame of the pressure chamber, thereby preventing the door from opening into the chamber. The pin module includes a cylinder for actuating the pin. The cylinder may be a pneumatic cylinder operated with pneumatic pressure. The pneumatic cylinder of each of the pin modules may be centrally actuated.

Abstract: A laryngeal airway device, having an airway tube which has an internal passage in the airway tube wall for receiving a cuff inflation line, and a dome having an inlet and an outlet, where the dome is connected at its inlet with the distal end of the airway tube. The device also includes an annular spoon-shaped inflatable cuff connected with the periphery of the outlet of the dome; a cuff inflation line configured to be in fluid communication with the internal space of the cuff; and a multi-lobed aperture formed in the dome. The aperture is configured to be in fluid communication with the proximal end of the airway tube. The dome has protrusions forming the multi-lobed aperture, such that a flap is configured to prevent the obstruction of the aperture by a patient's epiglottis when the device is inserted into the patient.

Abstract: A laryngeal mask includes an inflatable ring which has an outer periphery, an inner periphery with a welded edge projecting inwardly therefrom, and two opposite first and second wall parts extending respectively from the welded edge to the outer periphery. A gas supply tube has an open end which is connected to the inflatable ring along the welded edge, and a peripheral connection part hermetically sealed to the welded edge. A forward guide tab projects forwardly from the peripheral connection part and extends over a portion of the first wall part. Preferably, the forward guide tab is formed integrally with the peripheral connection part and is welded to the portion of the first wall part.

Abstract: Face masks for use in pressurized drug delivery applications, such as aerosol drug delivery systems, and a method of reducing aerosol deposition in the region of the eyes are presented. The face masks according to the various embodiments disclosed herein contain features that reduce the inertia of the aerosolized drug in perinasal areas. This results in a reduction in the amount of aerosolized drug that is deposited in the region of the eyes by inertial impaction, while at the same time, the features are constructed to maintain the flow of the aerosolized drug into the face mask so that the aerosolized drug is effectively delivered to the respiratory system of the patient.

Abstract: The present invention is generally directed to a respiratory delivery system (e.g. an inhaler) used to discharge an appropriate substance therefrom for inhalation by a user. The respiratory delivery system generally has at least one airflow inlet, at least one outlet (e.g., mouthpiece, nasal mask), at least one airflow passage extending therebetween, and at least one ejection actuator for discharging an appropriate substance into the airflow. The respiratory delivery system also generally includes an airflow regulation assembly that can adjust the size of a passage through which substantially all of the airflow is directed to achieve/maintain a certain flow rate through the inhaler.

Abstract: A connection device for connecting a headgear and a mask and a system for supplying a flow of gas to a patient that incorporates such a connection device. The connection device allows independent rotation of each of two independently disconnecting headgear connectors. The gas delivery mask includes a shell, a first connector associated with the shell, a second connector connected to a headgear and realeasably and rotateably connected to the first connector.

Abstract: The invention refers to a filtering system composed by a face mask and a filter against biological agents, joined together by a new connector. The connector joins the filter to the mask in an easy, fast and affective way. The filtering system provides a very high barrier against biological agents, a high seal and is very easy to use.

Abstract: An endotracheal tube pressure monitoring system for an endotracheal tube having at least pressure sensor in communication with a major lumen of the endotracheal tube, and a pressure monitoring subsystem in operative communication with the pressure sensor. The system may also have at least one fluid pressure line in fluid communication with the major lumen and in operative communication with the pressure monitoring subsystem to monitor the pressure of fluid within each respective fluid pressure line, and a purging subsystem in fluid communication with the fluid pressure line. Each fluid pressure line that is in fluid communication with the purging subsystem being selectively purged by the purging subsystem when pressure monitoring subsystem determines the respective pressure line has become obstructed. Purging the fluid pressure line maintains the patency of the pressure line so that accurate pressure measurements within the endotracheal tube can be obtained for calculation of parameters in lung mechanics.

Abstract: The present invention provides a device for generating a continuous positive airway pressure (CPAP device), in particular a nasal CPAP device (nCPAP device), with a hollow body (10) in which an overpressure can be built up; with a first opening (20) provided in a first side wall of the hollow body (10) and used for introduction of a respiratory gas flow (A) directed into the hollow body (10) and for removal of the exhaled respiratory gas flow (B); and with an attachment piece (30) which can be fitted on the hollow body (10) in order to connect the hollow body (10) to a nosepiece and/or mouthpiece (100). A second opening (71) is provided in a second side wall of the hollow body (10) and is used for introduction of a medicament flow (M) directed into the hollow body (10).

Abstract: The invention provides a filter mask for filtering air inhaled and exhaled from the mouth and nostrils while providing a positive facial lock at all edges of the mask. The filter mask has upper and lower edges which are provided with malleable stiffeners for conforming to the shape of the wearer's nose and cheek area and the lower jaw and chin area, respectively. The material of the filter mask is folded to have an omega pleat for forming a breathing chamber and a secondary pleat for assisting in securing the mask to the lower jaw and chin area. A pair of headbands are used to hold the mask on the head. The peripheral edges of the mask are bound. The mask provides excellent filtration since the positive facial lock around all edges of the mask substantially prevents air from leaking between the mask and the face.

Abstract: Apparatus, methods, and kits for treating symptoms associated with common ailments, such as headaches, rhinitis, asthma, epilepsy, nervous disorders and the like, are provided. The apparatus comprises dispensers for carbon dioxide and other therapeutic gases. The methods comprise delivering small volumes of these gases to patients in a manner where the gas infuses a body region in order to bathe the mucous membranes therein. It has been found that even very short exposure of patients to small volumes and high concentrations of such gases can provide significant relief from symptoms.
