Patent CA-2060223-A1 (CA)
Title: Injectable medical lubricating fluid composition and method of use
Inventor: LEE CLARENCE C
IPC: A61K38/08
Filed: 1992-01-29
Abstract: The present invention is an injectable medical device useful for replacing natural lubricating fluids in the body of humans or animals. The method and composition can be used for the treatment of joints and other parts of the body wherein natural lubrication between surfaces is deficient or where additional lubrication is required. The composition comprises a hydrophilic polymer suspended in a hydrophobic carrier so that the suspension is easily injectable into the desired body part. After injection, the carrier diffuses away from the polymer and is replaced by aqueous body fluids thereby causing the polymer to absorb or adsorb water forming a viscous, lubricating fluid.

Title: Process and device for producing mouldings, in particular for structural elements, insulations and/or packaging, and mouldings so obtained
Inventor: RETTENBACHER MARKUS
IPC: B27N3/28
Filed: 1990-06-05
Abstract: In a process for producing mouldings, in particular particle boards, at least one binding agent is mixed with a least one fine-particle basic material extruded at high temperature and pressure. The basic material has, or is brought to, a total content of 6 to 25 wt.%. It is extruded, together with at least one biopolymer, preferably a binding agent containing starch which can be con-vented to molten and/or gel form at least at the extrusion temperature and pressure, and the fine-particle material. Immediately after extrusion, the pressure is relieved by spontaneous expansion. The device for implementing the process comprises extrusion machines (2,20) for starting components in lump form. These machines have an extrusion nozzle (26,260) and an upstream pro-cessing region (204) where the basic material to be processed is partially pressure relieved by internal partial expansion. The ex-truded mouldings have a compact surface and a basic material in which particles of a fine-particle fibrous material are distribut-ed throughout a matrix containing numerous minute voids. The fraction of starch-containing matrix is equal to 5 to 85 wt.%.

Title: Soft-goods type, formable orthopeadic cast
Inventor: GRIM TRACY E
IPC: A61F13/04
Filed: 1990-09-20
Abstract: A soft-goods type foldable, wrappable sleeve orthopaedic cast (10) immobilizes and conforms to the shape and configuration of a limb (6), or other part of the anatomy. The soft-goods type cast assembly (10) is initiallly specially formed or configured to specifically fit a selected portion of the anatomy of a patient. The cast conforms to the anatomy through the use of airtight and moisture-proof pouches (12, 42) which encapsulate either (1) open cell or fiberglass matrices (24) impregnated with a water-activated urethane polymer, or (2) the entire assembly. After the tightening of the cast (10) around the limb (6), the application of water activates the urethane polymer which conforms to the configuration of the limb encased. Supplemental bendable ribs (32, 48) may be employed to splint the limb prior to activation of the hardenable material. The soft goods type cast (10) is held in place by straps (84, 86, 88), and may be removed or adjusted by releasing or tightening the straps. The splinting elements may be removed and replaced. An inlet duct (534 in Fig. 12) may have a capsule (536) in it with some of the chemical material which aids in polymerization of the urethane. A venting duct (532) may also be provided to permit the escape of air or gases.

Inventor: TELANG ANIL M
IPC: A61G7/05
Filed: 1992-02-24
Abstract: A stand-alone control module for use in closed-wound drainage systems is described. The control module transforms a variable high-vacuum source into a constant low-vacuum source. The control module also provides a one-way check valve to prevent return of air to a patient when draining such air from the pleural cavity of the patient. The control module is a water-based control module. It includes a first-suction control chamber (54) for transforming a variable high-vacuum into a constant low-vacuum. The first chamber (54) contains a first column of fluid (56) at a first pre-determined level. The module also includes a second water seal chamber (80) that contains a second column of fluid at a second pre-determined level. The height of the second column of fluid is less than the height of the first column of fluid. Tubes (58, 84) are placed in each chamber (54, 80) that have one end of each tube (58, 84) located below the columns of fluid. The column of fluid (56) within the first chamber (54) acts to regulate the vacuum within the chambers (54, 80) and the column of fluid in the second chamber (80) provides a one-way check valve to prevent air from returning to the patient.
