Abstract: The invention relates to a mask for administering oxygen or other breathable gas to the nose and mouth of a patient. The invention relates to improvements in gas delivery masks, and specifically an improved diffuser structure which is particularly suitable for use in an open mask system, in which the mask body includes substantial openings that allow the user to freely converse, drink, and perform other functions. The improvements also relate to a rebound chamber within the diffuser body spaced apart from the gas conduit outlet, the rebound surface being configured to rebound and reverse the direction of flow of at least a substantial portion of the gas stream exiting the outlet from the forward direction to a rearward direction towards the user's face.

Abstract: We disclose a mask for administering a breathable gas to a patient, which comprises a mask body and a gas flow disrupter joined to the mask body for generating a turbulent gas plume rearwardly towards the nose and mouth of the patient. The mask body is configured to position the flow disrupter so as to be spaced from and opposing the patient's nose and mouth region when the mask is worn by the patient. The mask includes a gas inlet for admitting gas from an external source into the mask interior, through the gas flow disrupter. The gas flow disrupter can be configured to generate a turbulent gas plume wherein the velocity of gas exiting the disrupter is approximately the same as the gas velocity entering the mask from the gas inlet.

Abstract: A closure for a container has a closure body having a first cylindrical portion and a second cylindrical portion opposite the first portion. The closure also has a connector disposed in at least one of the first and second portions. The connector is adapted to connect one of a sample collection device and an applicator to the closure. A containing apparatus including the closure, a container, and optionally one of a sample collection device and an applicator is also disclosed. A method of using the containing apparatus is also disclosed.

Abstract: An apparatus for protecting a syringe after use, the syringe comprising a body and a needle, the apparatus comprising a hollow member for receiving the body of the syringe, the hollow member comprising attaching means for securing the hollow member to the body of the syringe and a protective member slidably mounted on the hollow member and slidable between a syringe operating position wherein the protective member covers at least one part of the body of the syringe and a permanent final position wherein the protective member cover said needle of the syringe. The apparatus advantageously reduces the risk associated with handling a syringe after use.

Abstract: A lightweight oxygen delivery system for a patient comprising a curved resilient headband to extend from side to side over a patient's head and to be comfortably seatably engaged thereon. A clip is secured towards one end of the headband. An elongated tubular boom is secured at one end to the clip to extend and hold its position, when in operation from said one end at the clip to another end located at a space in front of, and proximal to the patient's nose and mouth. An oxygen diffuser port is located at the other end of the boom, to deliver oxygen from the boom to the space in the vicinity of the patient's nose and mouth.

Abstract: An oxygen diffuser for a lightweight oxygen delivery system for a patient, the oxygen delivery system being of the type comprising a mount for seated engagement on a patient's head or ear, an elongated tubular boom for oxygen delivery secured at one end to the mount and having the diffuser secured to the other end, the diffuser to deliver oxygen passed through the boom to a space in the vicinity of the patient's nose and mouth, the diffuser comprising a body having a wall, the interior surface of which wall is of generally concave configuration, circumscribing a centrally positioned oxygen outlet so as to direct the flow of oxygen from the outlet generally towards the patient's nose and mouth; and a baffle seated over the oxygen outlet so as to assist in mixing of oxygen with ambient air and avoid a direct flow of oxygen towards the patient's face.

An oxygen diffuser port is located at the other end of the boom, to deliver oxygen from the boom to the space in the vicinity of the patient's nose and mouth. The clip is constructed so as to hold securely an oxygen delivery tube from an oxygen source in fluid communication with said one end of the boom so as to deliver oxygen from the source to the boom for discharge through the diffuser.

Abstract: An apparatus is disclosed for converting vaporizers such as the Drager.TM. model 19 from pour-fill to safer indexed key-fill, and for providing overfill protection. A hollow screw is screwed up into an existing screw hole underneath the vaporizer that opens into the fluid storage compartment. A banjo encircling the screw provides two channels, one to dispense filling fluid up around the screw and into the vaporizer, and one to carry decompressing air back from the hollow through the screw. Each channel is connected to a separate pipe that communicates with a channel in an adaptor base screwed onto the vaporizer, and thereby to an indexed ISO key block connected to the fill bottle. Fluid thus flows from the bottle to the vaporizer and decompressing air flows back. For overfill protection, a special plug is fashioned to screw up into the existing sight glass access hole, and overfilling fluid flows from the vaporizer to the sight glass and then through the plug into the base where it exhausts.
