Abstract:
Nasal cannula device molded of a soft, flexible material includes a tubular member which supports a pair of integral cannula extensions. Openings at each end of the tubular member provide alternative connection points for an oxygen supply tube. An arch-like nose bridge engageable band member integrally attached to the tubular member outwardly of the cannula extensions has a layer of adhesive on its under surface for anchoring the cannula to the patient''s nose.
Abstract:
A container for adjusting the temperature of liquids such as blood flowing therethrough, which comprises a plastic envelope, heat sealed to define a tortuous fluid flow conduit therein. The conduit has an inlet and an outlet communicating with the exterior of the container. The outlet communicates with the interior of a drip chamber, the end of the outlet being spaced from the walls of the drip chamber to permit liquid passing from the outlet to fall a short distance through space, to indicate the rate of liquid flow, and to separate and entrap in the drip chamber any gas bubbles present.
Abstract:
One part by weight of streptokinase is chemically bonded to 1 to 500 parts by weight of a carbohydrate, to form a material which has improved stability compared with free streptokinase.
Abstract:
An improved method and apparatus are provided by which a selected radiation is passed through a test body and is subsequently measured, so as to determine the amount of the radiation absorbed by the body, and which involves the redirection of the radiation by retroreflective means through the test body directly back along its original path, prior to its detection by an appropriate radiation detector. In this way refraction effects due to flaws in the test body, which normally would direct random portions of the radiation away from the detector are cancelled, and the entire radiant beam is incident on the radiation detector despite such flaws.
Abstract:
A vascular canula which is intended for insertion into a blood vessel. The canula includes a thin-walled tube made of silicone rubber. The tubing wall is reinforced with thin fibers to provide a canula which combines softness and flexibility with stability of shape.
Abstract:
A METHOD OF SEPARATING LEUKOCYTES FROM WHOLE BLOOD WITHOUT AGGLUTINATION OF THE ERYTHROCYTES CONSISTING OF MIXING DEFIBRINATED WHOLE BLOOD WITH A LIQUID EXTRACT OF THE SEEDS OF THE FENUGREEK HERB.
Abstract:
A sealed bag for containing liquids. Typically made by a blowmolding process from a tube of molten thermoplastic resin. The bag comprises a tubular body of flexible plastic, sealed at one end, and narrowing to an integral tubular neck portion at the other end. A head portion, integral with the neck portion, seals the bag. A tubular recess is formed, typically in the head portion of the bag, for receiving a needle or the like for puncturing the bag to obtain the liquid contents. Generally, the cross section of the bag is oval, and a hanger at one end of the bag is attached thereto at a single station to facilitate collapse of the bag as liquid is withdrawn.
Abstract:
An automatic proportioner for proportioning a sample and a diluent for subsequent chemical analysis including a syringe driven by an actuator and controlled by a control system, a valve for selectively connecting the syringe to either a source of diluent in a receptacle or a source of sample, with diluent receptacle and valve being formed in a unitary assembly selectively removable from the main housing supporting the syringe and the control system components so that the receptacle, valve and syringe may be removed easily and replaced by another set.
Abstract:
A cannula is disposed about a stylet with a sharp forward end for incising the wall of an organ having a lumen for receiving the cannula from which, thereafter, the stylet is removable. The cannula may be collapsible for preventing fluid flow relative to the organ upon stylet removal, and thereafter defines a path, for inserting the catheter into the lumen. A slit extending longitudinally of the cannula may be provided to enable rapid stripping of the latter from the catheter which is longer than the cannula.
Abstract:
A PROTHROMBIN COMPLEX PREPARED FROM A PLASMA FRACTION CONTAINING FACTORS II, VII, IX AND X BY ADSORPTION WITH TRIBASIC CALCIUM PHOSPHATE, ELUTION WITH TRISODIUM CITRATE, AND MULTIPLE PRECIPITATIONS WITH POLYETHYLENE GLYCOL.
