The present invention relates generally to the fields of treating psychiatric disorders, in particular, anxiety disorders including post-traumatic stress disorder (PTSD) in subjects, e.g., human subjects, by administering a xenon and/or argon containing composition. Treatments can also employ psychotherapy in combination with administration of xenon and/or argon, alone or in combination with additional psychotherapeutic medications to treat the anxiety disorder and reduce a symptom of the anxiety disorder in the subject.

A needle guard for protecting a human or animal from accidental contact with a needle connected to said needle guard is disclosed. The needle guard comprises a mounting base for the needle, a hinge structure connecting the mounting base to a needle shield, and a needle shield hinge adjacent to the hinge structure and needle shield. The hinge structure is adapted to pivot the needle shield relative to the mounting base from an open position in which the needle shield is separated from the needle, to a closed position in which the needle shield encloses the needle. The needle shield hinge is adapted to pivot the needle shield relative to the hinge structure. A method of manufacturing the needle guard is also disclosed.

Embodiments herein relate to an implantable device comprising a casing, a semi-permeable membrane plug at or near a first end of the casing, a piston, beads, and an opening for release of the beads from the implantable device within a body of a human or an animal; wherein the implantable device is configured to be implanted within the body of the human or the animal during delivery of the beads into the body of the human or the animal; wherein the beads comprise a core and a shell with the core being enclosed by the shell and the beads contain a drug; and wherein the implantable device is configured to produce a desired flow rate of elution of the drug from the implantable device when the implantable device is implanted within the body of the human or the animal.

A device for administering a fluid can include a cylinder, a piston connected to a piston rod, and a tensioning device connected to the piston rod. In a dispensing procedure a ramp track is rotated until the roller runs over a transfer region and is accelerated toward the first plateau and, as a result, the piston is moved toward an open dispensing end. A motor is connected to the ramp via a coupling. To rotate the ramp, the coupling transmits torque provided by the motor in the first rotation direction and, in the process, provides a freewheel counter to the first rotation direction. The freewheel is configured such that it covers at least a rotation angle range which corresponds to the transfer region.

The invention relates to a medical ventilation apparatus (1) having a micro-blower (2) connected fluidically to a gas circuit (3) in order to supply said gas circuit (3) with respiratory gas, a controller (4) controlling the micro-blower (2), an electronic memory (8) configured to store at least several ventilation modes (Modes 1-6), and one or more patient category selectors (6) making it possible to select at least one given patient category from several selectable patient categories (6), and one or more ventilation mode selectors (7) making it possible to select at least one ventilation mode from among several selectable ventilation modes (Modes 1-6) based on the given patient category selected by means of said at least one patient category selector (6).

A portable gas delivery system 10 may generally comprise a gas container 20, a regulator 30, an adapter 40 to couple the regulator 30 to the container 20, and a tube or cannula 50 and/or a mask 60 fluidly connected to the container 20. Methods of making and using the portable gas delivery system are also described.

A partial enclosure for inhibiting sound passing into and out of the partial enclosure includes an absorber-barrier or an absorber-barrier-absorber, each made from sound absorbing material and sound barrier material and arranged to form the partial enclosure. The enclosure also includes an adaptive frequency matched sound-masking system. The absorber-barrier or absorbed-barrier-absorber is positioned to block or inhibit unwanted sound from various positions of a source of the unwanted sound, or motion of the source of the unwanted sound. The adaptive frequency matched sound-masking system includes a sound generating device arranged on or in the partial enclosure to emit anti-noise signal to cancel or inhibit the unwanted sound.

The sealing cuff (10) on a tracheal tube has a collar (31) at its patient end inverted within the inflatable part (32) of the cuff and attached with the shaft 1 immediately adjacent its patient end (6). The cuff (10) has a patient end region (33) of frusto-conical shape inclined to the axis of the shaft at about 30° and extending by about half the length of the inflatable portion.

An injection apparatus for sequentially injecting a patient with at least two medicaments may include a hand-held unit comprising a grip for being held by an operator, a single needle, a base unit coupled to the hand-held unit via at least one connecting tube, at least two containers for holding medicaments removably coupled to the base unit, and at least one pump. The at least one connecting tube can be flexible enough to enable easy maneuvering of the hand-held unit and rigid enough to prevent widening of the tube due to inner pressure when medicaments pass from the containers to the hand-held unit. The injection apparatus can be used to administer the at least two medicaments sequentially at different injection points.

A vent valve apparatus (10) for use with a system for supplying breathable gas pressurised above atmospheric pressure to a human or animal. The apparatus (10) includes a gas washout vent (15), a vent valve (18) adapted to progressively restrict the flow area of the washout vent (15), and a pressure sensitive vent valve control means (20,22,23). The control means is adapted to progressively cause the vent valve (18) to restrict the flow area of the gas washout vent (15) in response to increases in the pressure of the gas supply, thereby substantially regulating the volumetric flow of gas and/or CO.sub.2 gas through the washout vent (15) over a range of gas supply pressures.
