Apparatus for testing the pressures applied by a wound dressing plaster in vitro, comprises a scab model over a membrane covering a pressure sensor for the test plaster over it between cover plates

摘要

Apparatus to give an in vitro measurement of the pressures during the use of wound dressing plasters has a base plate (1) with a longitudinal cavity (2), covered by a flexible membrane (3) with a piezo element pressure sensor (4) at its under side. Apparatus to give an in vitro measurement of the pressures during the use of wound dressing plasters has a base plate (1) with a longitudinal cavity (2), covered by a flexible membrane (3) with a piezo element pressure sensor (4) at its under side. Cover plates (5,6) have a center opening (5a,6a) through them. A scab model (7) of suitable dimensions is placed on the membrane through the plate openings, over the cavity The plaster (8) under test is placed between the cover plates, to lie over the inserted scab model, as an adhesive or non-adhesive plaster dressing.
