Patent CA-1042298-A (CA)
Inventor: KRUCK RALPH E
IPC: A61M5/32

Abstract: ABSTRACT     A sealed hypodermic syringe comprising a cylindrical syringe body having a discharge opening at one end with a sealing mem-brane extending across the opening. A ferrule is disposed on the syringe body adjacent the discharge opening, the ferrule carrying a double-pointed needle and hub assembly arranged for longitudinal movement between an advanced position wherein the inner end of the needle is spaced from the sealing membrane, and a retracted position wherein the inner end pierces the membrane and communicates with fluid contained within the syringebody. A spring biases the needle to its retracted position, and a cover having a hollow bore houses the protruding portion of the needle. Press-fitted into the bore of the cover is an in-sert ring having locking shoulders which cooperate with ears the needle hub assembly to retain the needle in its advanced position against the action of the spring prior to the first use of the syringe.  To ready the syringe for use the cover is turned slightly.  This releases the advanced needle whereupon the action of the spring instantly snaps it to the retracted position.  The inner end of the needle thereby pierces the sealing membrane and communicates with the syringe chamber, enabling discharge therefrom to be effected.  Once the cover has been removed and the needle has snapped to its retracted, operative position, the cover can no longer be replaced and retained to house the needle.  Thus, prior use of the syringe will be indicated.  The advantage of the present invention over prior device of this type is that there is minimized any tendency toward binding between the ears of the needle hub and the locking shoulders on the cover.  In Addition, rotation of the cover through one-quarter turn completely releases the needle hub and readies the syringe for use.

Abstract: ABSTRACT OF THE DISCLOSURE     A suprapubic catheterization system features a suprapubic catheter having an advantageously large drainage lumen that con-sists of a stylet with a thin wall catheter external to it.  The stylet is a combination of a trocar or puncturing device that pre-vents tissue coring and a hollow cannula having side openings thereon that coincide with openings on the external catheter.          The openings on the cannula and catheter permit urine to flow through the proximal end thereof, thereby indicating that both tro-car and catheter are positioned correctly well inside the bladder.          The inner stylet can then be removed and a routine hook-up to the catheter can be accomplished.  The catheter tip may be coiled so as to assist in the retention of the catheter intracystically.          Irrigation of the bladder can be simply accomplished by inserting a luer fitting syringe into the system for irrigating a blocked catheter or the like.  The catheter may also be provided with a slidable locking mechanism for stabilizing the longer internal stylet type of catheter.  A preferred collet type device can be slid down the external catheter to a desired and convenient length prior to insertion and is locked in place, and can be made to have an adhesive coating on a side thereof so that the catheter may be affixed on the skin of the abdomen to prevent pull-out after its installation and during drainage.  The entire catheterization system can be pre-connected for ease of use and storage, and yet the individual portions thereof can be easily disconnected and separated from each other when used on a patient, for application of irrigation, sampling and medicine installation.

Abstract: ABSTRACT OF THE DISCLOSURE.      In order to recover platinum, rhodium and other precious metals from catalysts employed in internal combustion engine exhaust systems, the used or unused catalysts, preferably in crushed, powdered or broken form, are reacted with an acidic medium having oxidising properties to leach out the precious metals.   The acidic medium may be an acid containing or oxidising agent or an oxidising acid and when a used catalyst is treated the leaching step is preferably preceded by a reduction step in order to convert to the metal any precious metal oxides present in the catalyst.

Abstract: ABSTRACT OF THE DISCLOSURE         A vertical deflection circuit comprises a first tran-sistor, the base of which is impressed with a vertical synchro-nizing signal so that it is turned on during a vertical blanking period, while it is turned off during a vertical scan period, the collector of which is connected to a constant voltage supply and the emitter of which is connected to a capacitor so that the capacitor is charged to a predetermined voltage during the vertical blanking period.  A second transistor has its collector connected to the junction point of the emitter of the first transistor and the capacitor, and the base thereof is connected to another constant voltage supply.  Two resistors having a low resistance are inserted in series with a vertical deflection coil and the junction point of the resistors is coupled to the emitter of the second transistor through a feedback resistor.          The charge stored in the capacitor during the vertical blanking period is discharged through the second transistor during the vertical scan period.  Because of the feedback, the discharge current somewhat decreases at an earlier stage of the scan period as compared with at an intermediate stage and somewhat increases at a later stage, whereby a nonlinearity of the circuit between the capacitor and the reflection coils is compensated for and a vertical deflection current of a saw-tooth wave of high linearity is produced.

Abstract: IMPROVED NEEDLE COVER     Inventors:  David A. Bates Angelo T, Capritta ABSTRACT OF THE DISCLOSURE     A needle cover for blood collection needle or the like comprises a first sleeve positioned about a pointed hypodermic needle.  The first sleeve is removably carried by a hub, which also carries the needle.  In accordance with this invention an inner sleeve is provided, positioned within the first sleeve and about the point of the needle.  The in-ner sleeve is free of mechanical attachment to the first sleeve so that, upon rotation of the outer sleeve for its removal from the hub, the inner sleeve does not rotate with the first sleeve.  Accordingly, the danger of the pointed needle scourint out and retaining bits of plastic from the sleeve is eliminated.

A thermo-statically-controlled water distribution control device is associated with the conduits and is arranged for actuation of each inlet valve in inverse directions to maintain a predetermined water temperature in the mixing chamber.  A water flow blocking device is associated with each valve conduits upstream of the thermostatically-controlled device and is actuatable independently of the control device for blocking the flow of water through the conduits of both valves to prevent escape of water from the counterpressure chamber whereby the pressure in the counterpressure chambers increases until it presses the membranes into the closed position without actuation by the water distribution control device.

Abstract: ABSTRACT The invention relates to quantitative or qualitative assay of an antigen in a sample, in which one brings into contact in a liquid medium, an antigen which is selected from immunogens and haptens, and is insolubilized by being carried on an insoluble support or in the form of an insoluble aggregate, a first antibody which belongs to an immunoglobulin class and which is anti- to the insolubilized antigen, and an enzyme-labelled second antibody which is anti- to the immunoglobulin class of the first antibody and which is enzyme-labelled by a covalent linkage between the enzyme and the second antibody; separates the insoluble and soluble material; and determines the enzyme activity of the soluble or insoluble separated materials, thereby determining the presence or amount of antigen in the sample.  The improvement conferred by the invention lies in purifying said first antibody to remove antibodies non-specific to the insolubilized antigen, purifying the second antibody to remove antibodies non-specific to antibodies of the immuno-globulin class to which the first antibody belongs, preparing a pre-formed complex of the purified first antibody and purified first antibody and purified enzyme-labelled second antibody, and reacting the insolubilized antigen and the sample with said pre-formed complex, whereby the second antibody becomes attached to the insoluble material in inverse relationship to the amount of the antigen in the sample.
