Granted: 1988-01-07
Abstract: Part of the access monitor protrudes through openings (6,16) in the panel (2) of the hemodialysis machine, with gasket (3) providing an environmental seal. A releasable clamp (9) holds a pressure pillow (8) in contact with the rubber boot (7) covering the miniature push button switch (4). The clamp is held by a U shaped bail (10) pivoted about the point (12) to provide a quick clamp-and-release mechanism for the pressure pillow (8) connected in the blood tubing line.Under low pressure conditions, the tubing pressure is insufficient to hold the first pushbutton switch (4) closed and the switch signals a low pressure condition. Under high pressure conditions, the blood tubing pressure causes the lever arm (15) to pivot, so that its far end (19) actuates the second push button switch (20) to signal the high pressure condition

Title: A method for determining the mixing ratio of two or more compositions employed to prepare a polymer
Inventor: HILLSHAFER DOUGLAS K
IPC: G01N33/28
Filed: 1984-09-28
Granted: 1988-12-01
Abstract: Mixing ratio of two or more compsns. which are mixed and then cured to form a polymer is determined by adding a separate tracer cpd. in known quantity to each compsn. before mixing and curing. A representative sample of the cured polymer is reduced to small particles. The particles are subjected to solvent extraction to extract analysable amounts of the tracer cpds. The solvent is sepd. from the particles and analysed to determine the ratio of the tracer cpds.; the ratio of the compsns. used is thereby calculated. The tracer cpds. are non-reactive with each other the polymer and its ingredients and the solvent and have a boiling point above the max. temp. reached in prepn. or post-curing of the polymer.

Abstract: The invention encompasses methods of maintaining desired recombinant genes in a genetic population of cells expressing the recombinant gene. The methods utilize mutant cells which are characterized by a lack of a functioning native gene encoding an enzyme which is essential for cell survival, wherein this enzyme catalyzes a step in the biosynthesis of an essential cell wall structural component and the presence of a first recombinant gene encoding an enzyme which is a functional replacement for the native enzyme, wherein the first recombinant gene cannot replace the defective chromosomal gene. The first recombinant gene is structurally linked to a second recombinant gene encoding a desired product. Loss of the first recombinant gene causes the cells to lyse when the cells are in an environment where a product due to the expression of the first recombinant gene is absent. The invention also encompasses methods of creating and isolating mutant cells with the above characteristics. The cells of the invention are useful for commercial production of desired products, for components of vaccines for immunizing individuals, and for release into the environment.

Abstract: A cannula insertion needle (50) projects from the "forward" end of a hollow handle (10). After use to start a cannula, the needle is released from the end of the handle and its sharp end (52) retracted into the handle, beyond reach. Preferably the handle has an aperture (23) big enough for the needle but too small for fingertips. In one preferred form of the invention, the needle rides in a carrier block (30) that slides inside the handle. Initially the block is secured in the handle against the forward end, with the sharp end of the needle protruding outward through the aperture. A manually releasable latch (40) holds the block in this position. The latch mechanism includes mutually interfering stop elements on the exterior of the block and interior of the handle. After the cannula is in place, the person using the device withdraws the needle from the patient and manually triggers the carrier-block latch (42) by squeezing or rotating one of the stop elements out of engagement with the other. Then a coiled spring (61) drives the block rearward to retract the needle into the handle. At the rear end of the handle a stop (13) halts the carrier block and needle so that they are safely confined within the handle. A standard size tube fitting on the rear of the handle and a hollow needle permit liquid flow to or from the patient through the handle temporarily. <IMAGE>
