Abstract: A method and apparatus for performing assays in a single step which does not require the user to perform a washing step, does not require the user to add any reagent or other solution other than analyte sample fluid to the apparatus, and does not require the user to come into contact with the apparatus at any point during the assay procedure after the fluid suspected of containing a particular ligand is added to the apparatus. The apparatus for performing the assay consists of a single container with at least three ports disposed through different planes in the body of the apparatus beneath which labelled antiligand (the first port), unlabelled antiligand (the second port), and unlabelled ligand (the third port) are disposed. Said labelled antiligand is complementary to both the analyte of interest and the unlabelled ligand, the latter of which serves as a control display for comparison of any color changes mediated by the label visible through the second port.

Abstract: A portable suction system is provided for use with collection chambers for pleural drainage devices and for autotransfusion systems. The portable suction system comprises a small container having an inlet port for connection with a collection chamber or autotransfusion bag and an outlet port for connection with a suction source. The container includes a one-way valve system to prevent air from passing into the collection chamber or auto-transfusion bag and further includes a suction regulator and indicator to visually indicate the suction level.

Abstract: A suction regulator is provided for a pleural drainage device which includes a spring-loaded valve which opens to atmosphere to maintain the appropriate suction levels in the pleural drainage device together with an air flow regulator which reduces the air flow to the drainage device when the suction level from the suction source exceeds a predetermined level. A tapered passageway is provided in the air flow path from the suction source to the pleural drainage device and a ball valve having an opening therethrough is slidably disposed within the tapered passageway so that when the air flow through the passageway increases, the ball valve rises to decrease the amount of air passing through the passageway.

Abstract: Sweetness inhibitors which are substantially tasteless have been found to be bitter taste inhibitors or blockers. Conversely, bitter taste inhibitors which are substantially tasteless have been found to be sweet taste inhibitors or blockers.

Abstract: Rubber and vinyl articles such as gloves with improved slip coatings and processes for their production are provided by coating the outer and/or inner surfaces with either (1) a copolymer of at least one copolymerizable vinyl halide, at least one copolymerizable ethylenically unsaturated hydrocarbon and at least one copolymerizable ethylenically unsaturated monomer containing a carboxyl or amido group, (ii) copolymer of at least one copolymerizable vinyl or vinylidene halide, acrylonitrile and at least one acryulic monomer, or mixtures of (i) and (ii).

Abstract: An electronic monitoring system for a drainage device is provided with a bubble detector which transmits a signal upon the passage of a bubble through a bubble chamber of a surgical drainage device. There is provided a timing device which may be preset for any desired period of time. The timing device is connected to an alarm or signalling device which is activated to indicate the absence of passage of a bubble through the bubble chamber during the preset time interval. Switching means is provided on the timing device to selectively activate the timer initially to a short time period of a relatively few minutes and later to a long time period of several hours. The short time period is activated initially when the drainage device is first connected to a patient so that an alarm will be sounded to indicate possible malfunction of the device indicated by the absence of a bubble during a relatively short time period.

Abstract: Urethane-protected NCAs and MTAs are prepared by reacting an NCA or NTA with a haloformate in an inert diluent, under anhydrous conditions and in the presence of a tertiary nitrogen-containing base having an atom or functional group sufficiently electron rich and positioned relative to the nitrogen of said base so as to render said atom or group capable of complexing with the H--N< group of said N-carboxyanhydride or N-thiocarboxyanhydride but able to generate N-carboxyanhydride or N-thiocarboxyanhydride anionic complexes capable of reacting with the haloformate.

Abstract: A combined surgical drainage device and autotransfusion apparatus is provided in which a drainage device having a conventional collection chamber and suction regulating system may be readily converted into use as an autotransfusion system. The drainage apparatus has a fluid retention chamber disposed immediately beneath the inlet and a fluid outlet is provided in the bottom wall of the retention chamber with a spring pressed closure therein so that a nozzle on a collapsible autotransfusion bag may be inserted into the fluid retention chamber. The autotransfusion bag is collapsible and is provided with removable spreader means to maintain the bag in an expanded condition. When suction is applied to the drainage device, the interior of the autotransfusion bag is maintained at the desired suction level.

Abstract: An autotransfusion bag is provided with semi-rigid side walls and flexible material interconnecting the side walls. The bag is provided with spreader arms which extend across the top of the bag and across the bottom of the bag engaging retainer elements mounted on the external face of the side walls. The spreader arms maintain the bag in an open position to permit the bag to be filled with blood. When the bag is filled, the spreader arms may be removed to permit the bag to collapse as the blood is being reinfused to the patient.

Abstract: The invention relates to urethane-protected amino acid-N-carboxyanhydride and N-thiocarboxyanhydride compounds which are useful in peptide, polypeptide and protein synthesis. Disclosed herein is the preparation and use of these novel compounds.

Abstract: A liquid reinfusion bag system is provided for collecting blood from a surgical site and/or reinfusing the collected blood into the patient. The system includes a flexible bag having an external frame with locking elements to retain the bag in extended position during the time the bag is being filled, the locking elements being displaceable to permit the bag to collapse during the reinfusion process.

Abstract: A drainage device is provided with a disposable collection chamber which is attachable to a nondisposable section. The nondisposable section of the drainage device includes the suction control regulator and a valve to prevent admission of atmospheric air to the collection chamber. A receptacle is provided in the nondisposable section to indicate contamination of the nondisposable section in the event liquid from the collection chamber flows into the nondisposable section. A liquid biocidal chamber is provided in the collection chamber to prevent contaminates and infectious material from passing from the collection chamber into the nondisposable section.

Abstract: Methods and apparatus for maintaining urinary continence in normally incontinent individuals. The present invention involves the non-surgical implantation of a bolus of ferromagnetic material into the bladder. The bolus of ferromagnetic material may comprise a biocompatible membrane, containing a ferromagnetic material. The bolus will normally rest at the juncture between the bladder and the urethra and will prevent the flow of urine from the bladder into the urethra. Essentially, the bolus serves as a seal between the urethra and the bladder. When it is desired to void the bladder, the ferromagnetic bolus is moved out of the intersection between the bladder and the urethra by positioning a magnet along the external surface of the person's body and manipulating the magnet until the desired movement of the bolus is accomplished. Movement of the magnet is sufficient to displace the bolus such that flow may be initiated from the bladder into the urethra.
