Abstract: An improved multi-lumen catheter having lumens which do not extend in a straight line down the length of the catheter is disclosed. The twisting of the catheter provides that side holes which extend into the lumens of the catheter are not aligned in a straight line. Accordingly, when the catheter is inserted into a patient's vessel, the side holes cannot be aligned in a manner which causes all of the side holes of a particular lumen to be occluded by the wall of the patient's vessel.A catheter of the type disclosed can be manufactured by an extrusion process in which the catheter is twisted during the extrusion, or by heating a non-twisted catheter and then twisting it in order to impart an appropriate twist therein.

The body side of the apertured flange has a flexible skirt encircling the stoma aperture and located adjacent the radially inner boundary of the adhesive pad. The skirt is constructed and located to impede leakage of urine towards the adhesive pad.

Abstract: An improved ostomy appliance has two interengageable coupling elements, one of which (herein called the body side coupling element) is secured to a medical grade adhesive pad and the other side of which is secured to an ostomy bag. A flexible chute ring is interposed between the body side coupling element and the adhesive pad. The flexible chute ring is attached to a polymeric film surface of the pad at a first annular region and to the body side coupling element at a second annular region. The first annular region is located radially inwardly of the coupling element.

Abstract: A portable recorder has a pinch roller moved to engage a capstan, a recording head brought into a recording position and a motor to power the recorder switched on through the sliding movement of a slide assembly in engagement with the case of the recorder near a hinge between bottom and top portions of the case. The capstan is rotated about an axis substantially perpendicular to the plane of the case by a pulley arrangement driven by the motor with an axis substantially within a plane parallel to the case. The recording head is mounted to the slide assembly which includes a roller attached to the back thereof for rotating engagement with the case when it is opened and closed. Rotating movement of the roller causes the slide assembly to move back and forth within the case as the top of the case is opened and closed causing the recording head to move near or away from the tape. A spring mounted to the case and the slide assembly biases the slide assembly to a remote position when the case is opened.

Abstract: An apparatus and method for smoothing the reproduction of digitized waveforms on a raster scan line display by providing control signals which increase and decrease the electron beam pattern along the scan line in a trapezoidal pattern which is representative of the amplitude of the sampled waveform along that scan line. A microprocessor provides a plurality of digital signals which define the slopes of the increasing and decreasing ramps of the trapazoids and their starting points along the scan line. The digital signals for an entire frame of scan lines are stored during the frame blanking interval of the display and are accessed for each scan line during the scan line blanking interval. The digital signals are stored in a random access memory (RAM) at raster scan line addresses provided by the processor through a scroll counter and at digital signal addresses provided through a display controller.

Abstract: A crossed light beam coordinate detection and encoding system having a plurality of emitter/detector pairs along each axis of the display space is disclosed. The emitters are modulated in amplitude and the detectors are biased with a low load resistance to provide a wide dynamic range. The wide dynamic range and amplitude modulation detection provides immunity to unwanted interference. After band pass filtering, the carrier is amplified by high gain amplifier with auto bias control. The output of the amplifier generates a true/false output corresponding to the presence/absence of a beam. A single chip microprocessor controller checks the screen for interrupted beams and when not clear generates coordinates of the interrupted beams. The coordinates can be calculated as a weighted average of the interrupted beams for each axis or as the min and max coordinates along each axis. Reporting is done repeatedly at preselected time intervals.
