  • Patent number: 4747166
    Abstract: A urine aspiration system for the management of urinary incontinence comprising an absorptive pad adapted to temporarily receive and retain urine until it is drawn from the pad by an associated vacuum source. The pad comprises an absorptive core encased within a covering of hydrophobic material such as polyethylene sheet material. The upper cover sheet of the casing has a myriad of perforations to render it permeable to liquid, while the lower backing cover sheet is impermeable. Tubing from the vacuum source is coupled to a central opening of the pad so that urine may be readily drawn out of the pad when the vacuum source is activated, leaving the outer covering of the pad feeling dry and comfortable to the patient. A collection vessel is mounted between the vacuum source and the pad to collect the urine drawn from the pad.

  • Patent number: 4424815
    Abstract: A system for recording heart sounds from a stethoscope-type device and reproducing selected heartbeats stretched out in time but with the same pitch as recorded. In one embodiment the heart sounds are sampled and converted to a digital representations which are recorded on a tape recorder at a first speed. The tape recorder is of the endless loop recording and playback type. At a signal from the user, the tape recorder plays back at a reduced speed the last few heartbeats which are recorded. These are converted to analog signals and fed back to the transducer in the stethoscope for reproduction as natural heartbeat sounds merely stretched in time.Another system records the heartbeat sounds on a rotating recorder such as a magnetic drum. The magnetic transducer may be driven at variable speeds so that, when activated by the user, the speed of the playback transducer is reduced relative to the speed of the transducer during recording, without reducing the rotational speed of the drum.

  • Patent number: 4394037
    Abstract: An improved roller skate assembly in either shoe skate or skate board form is provided which includes a plurality of roller wheels, a frame securing the wheels in spaced relation for rotation and one or more spark generators, each comprising an abrasive surfaced disc or the like connected to a non-load bearing surface of one of the wheels and a sparking element such as a flint or material capable of generating colored sparks releasably held by a resilient flexible holder adjacent the abrasive surface of the disc. The holder vibrates during skating, due to ground shocks transmitted to it through the frame, bringing the sparking element into intermittent contact with the abrasive to intermittently generate sparks for a spectacular unusual effect. The holder preferably includes a metal or plastic coil spring and a fitting which releasably holds the flint and can be adjusted to reposition the flint as it wears.

  • Patent number: 4331162
    Abstract: A device for collecting a urine specimen, which is particularly adapted for females, is configured and adapted for use while the user is sitting on a toilet in the normal position for voiding. The device comprises a collector and a specimen container and selectively collects the clean, contaminant-free mid-stream portion of urine in the container. The urine specimen container is releasably secured to the collector at a bleed-off conduit extending from a collection exit in a uring receiving chamber of the collector. This exit is positioned in the chamber above a urine bleed-off exit in the conduit adapted for receiving and discarding the first-voided portion of urine at a controlled rate. The collection exit is remote from the bleed-off conduit exit, is shielded from urine splashing into the chamber, and is below a urine overflow exit in the chamber which leads to an overflow conduit. The chamber is preferably open topped and is adapted to be supported on the specimen container.
