  • Patent number: 5570682
    Abstract: A hand-held nebulizer system is provided which nebulizes during the patient's inspiration cycle only. The system includes a universal sensor port adapter which is adapted to fluidly connect an airway device with a sensor port of the system's source of pressurized gas in such a manner as to permit the patient to inhale and exhale atmospheric air, while permitting the use of standard airway devices. A unique valve arrangement is also provided in the device for supplying the pressurized gas which permits the system to be extremely sensitive to small pressure differentials, thereby ensuring that the system detects the respiratory cycle phases of even the weakest patients.

  • Patent number: 5505686
    Abstract: An endoscope including an elongated endoscope body sized and adapted for insertion into a passage, such as a passage of the body of a patient. Optical components are carried by the endoscope body to enable viewing of the passage distally of the distal end of the endoscope body within a field of view of the endoscope. An elongated, resilient member is mounted on and carried by the endoscope body such that the endoscope body and the resilient member are a unitary assembly which can be inserted as a unit into the passage. The resilient member extends beyond the distal end of the endoscope body and is capable of contacting material within or forming the passage and relatively displacing the distal end of the endoscope body and such material within the field of view of the endoscope to enhance viewing of the passage with the endoscope.

  • Patent number: 5462052
    Abstract: A sensor cassette for use in measuring a compositional parameter of blood comprising a housing having a wall defining a passage which is adapted to receive blood. The wall is at least somewhat permeable to the compositional parameter. A support element, which is less permeable to the compositional parameter of blood than the housing, is carried by a region of the wall. A sensor is carried by the support element and provides a signal in response to the compositional parameter. The support element separates the sensor from at least a portion of such region of the wall so that the affect of the permeability of the housing to the compositional parameter on the signal from the sensor is reduced.

  • Patent number: 5423929
    Abstract: New intraocular lenses (IOLs) and methods for producing IOLs are disclosed. The present methods include a combination of steps which increase the pull strength between the fixation member of the IOL and the optic of the IOL without requiring sophisticated high frequency corona discharge activation or plasma activation of the fixation member. The fixation members are doubly coated with primer components and silicone polymeric material precursor compositions before being secured to the optics. In addition, the optic members employed in the present invention can be formed, for example, molded, without recesses to accommodate the fixation members. Thus, such recesses can be formed and provided with a quantity of the above-noted precursor composition after the optic members are produced. The doubly coated fixation members are then placed in the recesses and secured to the optic members. The present methods are straight forward, easy to practice and are cost effective in producing high quality IOLs.

  • Patent number: 5413282
    Abstract: An emitter for use in irrigation comprising a housing and a flow restrictor in the housing. The housing has an inlet which can be connected to a source of irrigation liquid and an outlet. The flow restrictor reduces the pressure of the irrigation liquid to provide drip or trickle flow at the outlet. A spike flow inhibitor is provided in the housing for substantially preventing flush flow through the housing upon initiation of the flow of irrigation liquid through the housing. The flow restrictor is responsive to at least a predetermined reduction in pressure of the irrigation liquid at the inlet for causing flush flow through the flow restrictor.

  • Patent number: 5413371
    Abstract: A binding block for elevating the binding on a snow ski in order to achieve increased turning leverage has a mid-region wherein maximum ski flexibility is permitted. In one embodiment, the binding block is comprised of two separate elements forming a gap between them in order to provide such maximum flexibility. The binding block is constructed from a lightweight, flexible yet compressible material so as to not inhibit the natural flexibility characteristics of the ski, while at the same time performing the desirable function of absorbing or dampening ski vibration. In another embodiment of the invention, the binding block is slidably mounted on the ski so as to move relative thereto in response to the flexing of the ski, thereby enhancing the flexibility of the ski and the "feel" thereof by the skier.
