Abstract: A liquid collection system for collecting and discharging urine from a catheterized patient. A collection bag receives urine through the catheter, and has a drain system therein, which comprises a valve having a bactericide element over which the urine must flow as it is being drained from the bag. The bactericide element is held in an openable cage, so as to permit replacement of the bactericide element as an "as needed" basis. The bactericide disposed within the valve helps prevent retrograde contamination of the liquid collection system.

Abstract: A tamper-evident band for a liquid drainage system comprising an elastic catheter having an elongated shaft, a connector adjacent the proximal end of the catheter, and a drainage lumen extending through a major portion of the catheter and the connector. The tamper-evident band comprises elastomeric annular band of stepped diameter which is fit over the juncture between the connector and the proximal end of the catheter. The band has a slot longitudinally arranged on one outer peripheral portion of the band. It also has a semi-circumferential tear tab disposed on one end thereof. To separate the connector from the proximal end of the catheter, the band must be broken. The tab may be pulled and the band separated along its longitudinal slot. A small ring comprising the remaining stepped portion of the band remains on the adapter after the tab has been pulled, the slot fractured and the top band portion removed.

Abstract: A fluid sampling chamber assembly for noninvasive sensing of a fluid having a chamber with a sensor wall for acoustic coupling therewith, an apparatus for coupling a transducer of a transducer assembly with the sensor wall, a preapplied acoustic coupling agent and a relatively rigid connector member mounted to the chamber around the sensor wall with a portion around a probe access opening in retentive overlying relationship with the acoustic coupling agent to prevent run off of the coupling agent before use. A cover is releasibly attached to the connector for protectively covering the access opening and sensor location. The cover permits gaseous sterilization of the sensor wall because ribs carried by the releasible attaching means block the releasible attaching means from making a gaseous tight seal with the connector.

Abstract: An automatic urinary output monitor including a means for noninvasively determining the specific gravity of urine in a urine collection system including an oscillator with a feedback loop including ultrasonic transducers at opposite sides of a sampling chamber for producing an output signal with a frequency determined by the period of time it takes for a transmitted ultrasonic pulse to travel through the urine sample and to be received and means responsive to the frequency of the output signal for providing an indication of specific gravity of the urine sample.

Abstract: Apparatus for correctly aligning a pair of sensor probes relative to a sample chamber location in a biological fluid sensor apparatus for sensing fluid in a sample chamber.

Abstract: Device for tensioning a shoe upper on a last and for laying its lasting margin over in the ball and shank region, wherein the shoe upper is first pressed against the last by means of a presser member, whereafter a band secured to the presser member is tensioned about the shoe upper in a direction towards the last bottom. The bands which embrace the last from both sides are brought together in tension in the middle of the insole.

Abstract: A lockstitch sewing machine has, in addition to stitch forming instrumentalities (22, 24), a needle thread control arrangement (32) by which the tension in the needle thread (T2) is controlled during stitch formation. In addition, said arrangement (32) ensures that each formed stitch is drawn into the body of the workpiece, by pulling on the thread while it remains clamped by thread clamping means (200, 202). This pulling takes place in the early stages of the formation of the next stitch so that, at the end of the machine stitching cycle, the final stitch is not set by this arrangement (32). Instead, electrically actuated stitch setting means (220 to 226) is provided operable in response to an "end of cycle" signal supplied by control means by which further "end of cycle" functions (e.g. release of a presser foot (36) and of the thread clamping means (200, 202) are also controlled.
