Abstract: An improved flow based incentive spirometer operable through a range of user set flow rates and being adapted to receive a supplemental flow of Oxygen without requiring any change in the calibration of the device or effecting the patient's monitoring of usage. In this manner the spirometer may be utilized by a range of patients having quite distinct therapy needs. The device also features an integral information display receptacle in the base for storage of operational instructions. A portion of the base is transparent to that the information contained in the storage receptacle can be viewed by a patient while the device is in use, thereby permitting a patient to observe such things as the instructions for proper use of the incentive spirometer while using the device.

Abstract: An improved maximum expiratory pressure device and cough simulator including a flow tube having an integral mouthpiece at a patient input end, and a hinged door at an opposite or discharge end for sealing off the flow tube. The hinged door is held closed by a releasable trigger operable by the patient to release the door after pressure build up to simulate a cough. A foldable pressure monitoring port is provided to connect the maximum expiratory pressure device to a pressure gauge, if desired, for monitoring the expiratory pressure developed within the flow tube.

Abstract: A trocar system includes a cannula having a cannula head and a cannula tube, and an obturator having a cap and either a rounded tip or a cutting blade. The head and cap form an ergonomically shaped bulbous handle. At least a portion of an outer surface of the cannula head may include a resilient non-slip material. The cannula head may also include a monolithic housing having a port with a Luer Lock fitting and an integrally formed passageway for receiving a stopcock valve.

Abstract: A surgical trocar device having an obturator and cannula that requires less force to insert and remove from tissue. The cannula includes a head assembly and the obturator includes a cap assembly that have cooperating surfaces that bear against each other so that when the obturator is rotated about its axis the obturator is axially deflected within the cannula and thus more easily removed from the tissue into which the obturator is inserted. The tip of the obturator and the end of the cannula are designed to minimize tissue damage and insertion effort by providing a smooth, unencumbered surface transition. In one aspect of the invention, the tip of the cannula is smooth, continuous, and flexible and can radially deflect when the larger-diameter obturator is inserted or withdrawn though the cannula.

Abstract: This door and frame for electronic component cabinets features a peripheral vent with a baffle that substantially encompasses the entire 360-degree periphery of the door. This vent and baffle combination provides ventilation for the purposes. of the electrical equipment when the door and frame are mounted to an electronic component cabinet. It also helps to avoid dust invasion and helps to eliminate dangers that can arise due to the insertion of objects into the cabinet by small children. In addition, it is invisible from the front of the component cabinet and is sleekly attractive from the front and side.

Abstract: An eyewear loupe which is adaptable to various types of eyewear frame and provides a sub-area of magnification. The loupe is easily removed from an eyewear frame and reattached. The loupe can be worn on either side of an eyewear frame.

Abstract: An electrical receptacle for electrical connection to insulated electrical conductors comprises a dielectric housing (12) including a first housing section (22) and a second housing section (24); first and second electrical contact members (38, 40) disposed in the dielectric housing (12) and having first contacts (38b, 40b) in alignment with slots (26, 28) of the dielectric housing and second contacts (38a, 40a) in alignment with openings (58) of the dielectric housing including insulation-displacement contacts; and conductor-moving members (16, 18) associated with the insulation-displacement contacts-for moving the insulated electrical conductors into the insulation-displacement contacts thereby effecting electrical connections between the insulation-displacement contacts and the insulated electrical conductors.

Abstract: An electrical component (10, 110, 210, 310) for electrically connecting insulated electrical conductors (56) thereto comprises a dielectric housing (12, 112, 212, 312) including a first housing section (20, 118, 218, 318) and a second housing section (22, 120, 220, 320), first and second electrical contact members (42, 44, 158, 160, 240, 242, 334, 336) disposed in the dielectric housing and having first contacts (42a, 44a, 158a, 160a, 240a, 242a, 334a, 336a) extending into the second housing section and second contacts (42b, 44b, 158b, 160b, 240b, 242b, 334b, 336b) positioned within the first housing section, insulation-displacement contacts (42a, 44a, 158a, 160a, 248, 348) as part of the first contacts along which the insulated electrical conductors are positioned, and conductor-moving members (16, 18, 154, 156, 250, 346) for engaging the insulated electrical conductors and moving them into the insulation-displacement contacts thereby forming electrical connections between the insulation-displacement contact

Abstract: An electrical safety receptacle (10) including a dielectric housing (12), first electrical contacts (14) in the housing for electrical connection to one side of an electrical power line, second electrical contacts (16) in the housing for electrical connection to the other side of the electrical power line, and power-interruption members (48) provided as part of the second electrical contacts to interrupt the electrical power when an operating and/or environmental temperature exceeds the thermal rating thereof.
