Abstract: A pressurized respiratory gas humidifier adapter with a pressure relief valve having an audible signal generating device incorporated into a low-flow respiratory gas supply system at a position in the system wherein the pressure relief valve and an audible signal generating device are protected from inadvertent damage during use of the humidification system, especially during connection of the adapter into the respiratory gas supply system and when the adapter is connected to a humidifier container prior to coupling into the gas supply system.

Abstract: To enable a user to readily determine the gauge of the needle of a needle assembly that has a base and a needle protective housing pivotably attached thereto, the needle assembly is injection molded from a color coded molding material which color was preassigned to correspond to the gauge of the needle. As a result, both the base and the protective housing of the needle assembly are the same specific color, and reflect or provide an indication of the given gauge of the needle. The needle sheath that covers the needle prior to use may be made of a plastics material that may be clear, or have the same or a different color than that of the needle assembly.

Abstract: The present invention safety device is a one-piece needle assembly that has a base and a housing pivotally connected to the base. The base has a distal portion to which a needle is fitted. At the base there is formed longitudinally along its distal portion a catch mechanism that may be in the form of an anchor projection. At the back wall of the housing there is extended another catch mechanism that may be configured in the form of two clasping fingers. Also providing in the housing is an integral hook. As the housing and the base are pivoted relative to each other, and as the needle makes contact with the hook, the respective catch mechanisms at the base and the housing also make contact with each other, resulting in the coupling of the catch mechanisms and the coupling of the needle to the hook. As a result, the catch mechanisms are interlocked and the needle is fixedly retained by the hook within the housing.

Abstract: A fluid transfer system has a holder that is made of a cylindrical member having a closed end and an open end. The closed end has fitted thereto a luer and a cannula that extends into the interior of the holder. The holder has a distal portion that has a first cross section and a proximal portion that has a second cross section. The cross section of the distal portion is smaller than the cross section of the proximal portion. The distal and proximal portions are joined by a shoulder. The fluid transfer system also includes an adapter that is inserted to the holder from the open end of the holder. The adapter has a base having a central opening and a cylindrical tube that extends from the central opening. The diameter of the cylindrical tube is slightly smaller than the diameter of the distal portion and is configured to accept a first type of fluid collection store such as a vacuum tube. A non-continuous wall extends from the base of the adapter to surround the cylindrical tube.

Abstract: A safety needle assembly has a collar or ring that is rotatably mounted to a needle hub, which may be connected to a medical device such as a syringe. The needle assembly may be connected to the syringe by the user grasping the needle hub in first and second embodiments, or turning of the needle sheath in other embodiments. In all of the embodiments, the collar of the needle assembly may be rotated by turning the needle sheath, which is designed to interact with the collar. In some of the embodiments, the needle hub likewise interacts with the collar in such a way that by rotating the needle sheath, the needle hub is likewise rotated for connection to a syringe. When an exposed needle is to be covered, after the needle sheath has been removed, a housing connected to the collar is pivotally moved to cover the needle.

Abstract: A safety needle assembly has a needle hub having a proximal portion and a distal portion. Integrally formed from the proximal portion is a ring that surrounds the luer base portion of the needle hub. Windows are provided at the sidewall of the ring to enable a user to see the base portion of the needle hub. At the distal portion of the needle hub there are coaxially formed circumferential flanges. The space between the flanges and the end wall of the ring surrounding the luer end of the needle hub is dimensioned to accept protrusions at the inner surface of the proximal portion of a collar. Once mated to the space at the needle hub, the collar is rotatable, although not freely, about the needle hub. A needle protection housing is connected to the collar and is pivotable to cover the needle that extends from the distal end of the needle hub.

Abstract: An attachable housing for holding, carrying, and using an elongated personal item (such as a dispenser for lip balm, lipstick, or eye shadow, or a small flashlight). The housing comprises a body having an insert opening through it. The body has an inner wall adapted for receiving the personal item. The inner wall has one or more elastic compressible protrusions that grip the personal item when it is inserted into the housing. The personal item is fully useable while in the housing. The housing can be made for use with personal items that have an operating mechanism (such as a wheel) at the bottom; the midsection, or the top; or no operating mechanism. In an embodiment intended for personal items with a bottom-located mechanism, the housing has a base connected to the body bottom by support(s), and the mechanism is accessible through a base opening defined by the base, base support(s), and body bottom, and the base has a pivot acting as a seat for the personal item.
