Abstract: A mouth-to-mouth resuscitator device for providing a physical barrier between a rescuer and a victim including a hollow tubular housing having an air input end and an air output end and counting a self closing one way valve having a disc shape secured between the housing ends and a pair of spaced apart rods secured to the disc for attaching the disc to a support plate, so that the inner end of the plate is received between the rods to support the valve disc and provide a hinge for dividing the disc into a pair of flaps to bend outward to an open position in response to forced air for transferring the air from the air input end to the air output end, and the flaps resiliently return to a closed position when the forced air has dissipated.

Abstract: A fastening arrangement for a limb support device includes a formable jacket having a top side and a bottom side. An injured limb or body part is positioned on the bottom side. The jacket is formed to the desired shape for supporting and protecting the limb. A belt holder having an opening is rigidly secured to the top side. A belt passes through the opening of the holder. A stud is pivotally attached to the belt and extends outward from the upper side of the belt. The stud abuts the holder to anchor the stud against the holder and prevent movement of the stud and belt through the opening of the holder when the belt is pulled in one direction. This maintains a fixed length of the belt from one end of the belt to the anchored stud. The ends of the belt are connected together after the stud is anchored.

Abstract: A valved bandage and method for covering an open wound in the chest cavity. The bandage includes a flexible sheet having a hole formed therein. A normally closed one way valve section extends outward from the outside of the sheet and in communication with the hole. The bandage is secured over the chest wound, so that the valve is in alignment with the chest wound opening to close the chest wound. The bandage enables fluids from inside the chest cavity to flow into the valve, to open the valve and be released to the outside. The valve automatically closes after the flow of fluids into the valve substantially ceases, to prevent back flow of air from the outside to the inside of the chest cavity. The one way valve section of the bandage may be formed into an angled configuration, so that the position of the outlet of the angled valve section may be varied to provide optimum drainage of fluids.

Abstract: A container for fluids having a valve positioned inside and adjacent to a fluid supply opening. The valve has an open condition to provide a fluid inlet passageway and a closed condition to close the fluid inlet passageway. An outer pocket is secured on the outside of the container, isolated from the fluid supply opening. Upon opening the pocket outward, the valve moves responsively from the closed condition to the open condition.

Abstract: A resuscitator device for providing a physical shield between the rescuer and a victim requiring mouth-to-mouth resuscitation. The device comprises a flexible sheet having an opening centrally formed therein and a rigid tube secured to the sheet around the periphery of the opening for inserting into the mouth of the victim. A self closing one-way valve is contained in the tube and extends downward from the sheet opening and includes a flexible sleeve normally held closed at the outer end thereof by the action of a spring formed from a strip of rigid and flexible material secured to the outer end of the sleeve. The rescuer exhales a deep breath into the input of the valve via said opening in the sheet, to overcome the resilient force of the spring for discharging forced air into the mouth of the victim. After the rescuer has fully exhaled, the spring strip resiliently closes the valve to prevent any back flow of air, mist or liquid from the victim to the rescuer.

Abstract: An improved method and apparatus for effecting mid-stream sampling of catheterized flow of liquid from a body cavity is effected through use of an improved coupling between sections of catheter tube means. The improved coupling includes a tubular cross-member that provides two pairs of oppositely extending tubular arms, a first pair of arms adapted to connect to the portions of the catheter tube means, and with a valve member constructed and arranged for selective reciprocal movement in the other pair of tubular arms and so as to permit usual drainage in one position or to provide, in said second position, means for effecting diversion of flow for effecting mid-stream sampling without separating portions of the catheter system that might permit contamination. In the second position, the constructions permit of effecting a backflow flushing of the body cavity, or application of medication, or an instrument, through the improved coupling into the body cavity.

Abstract: A combination catheter venting and urine sample collecting unit comprises a hollow open-ended body having an outlet and adapted to receive and communicate with a conduit extending to a urine collecting reservoir and an inlet adapted to receive and communicate with a catheter extending to the bladder. The body further has a urine collection needle-receiving port and a number of circumferentially spaced venting apertures spaced longitudinally of the said needle-receiving port. A strip of bacteria and liquid impermeable, and air-permeable filtering material is positioned in liquid-sealing relation beneath the venting apertures. The filtering material is carried on the outside of an open-ended support tube having circumferentially spaced apertures in alignment with said venting apertures. The support tube is enveloped by said body which is preferably molded about the tube. The body has a continuous outer annular indented wall surface upon which the needle-receiving port opens.

Abstract: A unitary wheel and tire assembly comprising an injection-molded, thermoplastic wheel and a tire which is injection-molded on the wheel. The tire is of elastic material, such as synthetic or natural rubber, and having irregular inner surface portions complementary to the irregularity in the confronting surface portions of the wheel to bring about a reliable mechanical interfit.
