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. Before use, the needle extending from the needle hub is covered by a needle sheath that has a groove formed circumferentially at its proximal end that snap-fits to a circumferential rib formed at the distal end of the collar. The safety needle assembly is connectable to a medical device such as a syringe by the user grasping the ring of the needle hub and coupling the luer of the needle hub to a corresponding luer at the syringe.

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. Mechanisms are provided at both the collar and the housing so that once the contaminated needle is covered, the needle assembly may be removed from the syringe for disposal by rotating the needle housing. In all of the embodiments disclosed, the needle sheath does not come into contact with the needle hub and the collar is rotatable about the needle hub.

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.

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. The cross section of the wall is slightly smaller than the diameter of the proximal portion. At each section of the non-continuous wall there is formed a protuberance. A groove is formed about the inner surface of the proximal portion. When the adapter is fully inserted to the holder, the protuberances would snap fit to the groove so that the adapter is prevented from being inadvertently removed from the holder. With the adapter removed, the holder can accept a differently dimensioned fluid collection store such as for example a blood culture collection bottle.

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. The catch mechanisms may also be configured as a hook and a latch in the form of a rib with an opening whereto the hook is fixedly coupled. The gauge of the needle may be determined by the color of both the base and the housing, which are molded as a unitary single unit.

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. The pressure relief valve and audible signal generator are incorporated into a humidifier adapter for creating a hermetic seal with a standard medical humidifier container, and the pressure relief valve relieves and regulates the pressure in the humidified gas supply system when an obstruction in the gas flow path to the patient occurs, while generating an audible sound emitted at a predetermined pressure threshold level throughout a desired respiratory gas flow-rate range.
