Abstract: A device for collecting contaminants from water samples is provided. The device includes a solid sorbent that collects and stores the contaminants from water samples. The solid sorbent is configured to allow for the preservation of the stored contaminants. The concentrations of the contaminants in the water samples are determined via analysis of the solid sorbent or via elution of the stored contaminants from the sorbent and analysis of the eluate solution.

Abstract: An aerosol inhalation device assembly for diagnostic and therapeutic use for deep lung alveolar aerosol targeted drug delivery includes a nebulizer for generating an aerosol containing droplets of a liquid. The nebulizer has a pressurized gas inlet and a nebulizer outlet. An inhalation chamber is in fluid communication with the nebulizer outlet. The inhalation chamber is defined by at least one sidewall. An inhalation mouthpiece assembly is in fluid communication with the inhalation chamber and extends outwardly from the at least one sidewall of the inhalation chamber. A filter assembly is in fluid communication with the inhalation chamber. The filter assembly includes a filter medium. An exit port is in direct fluid communication with the filter assembly. A method of using the nebulizer is also provided.

Abstract: An exercise apparatus comprising an elongate support member, an exercise attachment, a frame member, and lateral arm supports is provided. The elongate support member is removably attached to a support frame of the exercise apparatus. The exercise attachment, for example, a rod member, a strapping element, etc., is connected to a lower end of the elongate support member via a pulley system for supporting the user's arms and/or legs. The pulley system comprises a first pulley connected to the lower end of the elongate support member, and a cable rollably attached to the first pulley. The frame member is rigidly attached to the elongate support member. The lateral arm supports are rigidly attached on opposing sides of the frame member. The lateral arm supports extend outwardly from the frame member for supporting the user's arms. The user utilizes the exercise attachment and/or the lateral arm supports for performing an exercise.

Abstract: An exercise apparatus comprising a clamping assembly, one or more adjustment plates, one or more pivot plates, and a weight bearing assembly is provided. The clamping assembly comprises claw members, each comprising a vertical web and horizontal flanges extending from the vertical web. The horizontal flanges detachably clamp to a support structure. The adjustment plates are rigidly attached to the vertical web of one of the claw members and comprise apertures for enabling positional adjustment of the weight bearing assembly. The pivot plates are rigidly attached to the vertical web of another one of the claw members. The weight bearing assembly comprises a leg member rigidly attached to a support frame, and gripping handles. The leg member is pivotally connected to the pivot plates and detachably connected to the adjustment plates. The gripping handles that are rigidly supported by the support frame are held by a user for performing exercises.

Abstract: Improved aerosol inhalation devices are provided. The devices include an aerosol source for generating an aerosol; a first conduit, having a proximal end, the first conduit providing passage of the aerosol to the patient; a first chamber at the proximal end of the first conduit, adjacent to the aerosol source; a second conduit providing passage of gaseous medium from the patient; a second chamber; and a first valve disposed between the first chamber and the second chamber. The first valve remains closed during exhalation by the patient and opens at least partially during inhalation. The device also includes a second valve disposed between the second conduit and the second chamber, which remains closed during inhalation by the patient and opens at least partially during exhalation by said patient. The gaseous medium exhaled by the patient can optionally contain material of which the aerosol is formed, such as liquid droplets.

Abstract: Improved nebulizers and aerosol inhalation devices including these nebulizers are provided by this invention. The disclosed nebulizers are suitable for supplying an aerosol mist to a patient and include a liquid inlet for receiving a liquid, a gas inlet for receiving a pressurized gas and an aerosol outlet for providing an aerosol mist. An important aspect of this invention is the addition of gas swirling means or flow controlling means for creating a swirling action or a tangential velocity to the gas forming the aerosol. The nebulizer and other devices of this invention can produce an aerosol mist having an obscuration of at least 10% and a median droplet size of less than 1 .mu.m.

Abstract: Improved aerosol inhalation devices including a nebulizer and a rain-off chamber for returning droplets of liquid medication or diagnostics exhaled by the patient back to the nebulizer for reatomization.

Abstract: An improved filtration device suitable for reducing exhaled particles in an aerosol inhalation device. The filtration device includes a body portion having an interior chamber which communicates with an inlet and outlet opening through the chamber wall. Within the chamber is a substance recovery media designed to capture a portion of the exhaled particles from the patient and for assisting in returning a portion of the captured particles back to the patient, such as by a nebulizer. The filtration device further includes a filter layer located within the interior chamber for filtering out contaminants, such as viruses and bacteria, in the gaseous medium prior to releasing the remaining portion of the gaseous medium into the environment. Aerosol inhalation devices containing such filters are also provided by this invention.
