Title: Ascertaining compression pressure of orthopaedic stocking - measuring pressure needled to bring stocking e.g. through air pressure to same expansion
Inventor: FISCHBACH JOERN-UWE DR RER NAT
IPC: A61F13/00
Filed: 1989-10-25
Abstract: The procedure allows the compression pressure and its process that the orthopaedic compression stocking locally exercises on the extremity to be measured. The pressure is measured that is needed to bring the stocking to the same expansion which is mechanically caused by the extremity, e.g, patient's leg. For this purpose, a sack impervious to air (7) is inserted in the stocking. Extension in length by inflation is prevented by similar stockings (6') symmetrically placed at the proximal and distal parts. A calibration chart is derived through stepwise inflation. The associated pressure is derived from the local expansion of the extremity. ADVANTAGE - No touch technique for routine practice.

Title: Chain driven transport trolley with drive disengaging mechanism - in which wheels have one way clutch and are mounted on castors
Inventor: HICK ROLAND
IPC: B60T7/22
Filed: 1989-12-22
Abstract: A transport trolley driven by an underfloor drag chain has an impact device (14) which disengages the drive when the trolley meets an obstacle by withdrawing the drive member from the chain through the action of cam (20) on roller (19).
