VALVES ENABLING A LIQUID TO BE DIRECTED IN A DIAGNOSTIC CHART, DIAGNOSTIC CHARTS AND DIAGNOSTIC DEVICE COMPRISING SEVERAL CHARTS

摘要

The invention relates to a valve (2) through which at least one channel (3) flows, enabling at least one liquid (F5) to be directed and moved by transfer means within a diagnostic chart (1). Said chart (1) comprises at least two surfaces (4, 5) which are joined (4) to each other (5) by means of an edge (6). The invention also relates to a chart fitted with said device,enabling several charts fitted with said valves to be used together. The inventive valve is made of a film (7) which is flexible and/or can be deformed, and partially fixed on at least one of the surfaces (4 and/or 5) of said card, in addition to a means for compressing said film (7) which can be de-activated. Fixing occurs on at least one of the surfaces (4 and/or 5) planar for example by means of a fixing device which is located on the peripheral indent (9) of said valve (2) - a groove (9) for instance. Preferably, the invention can be used in the field of diagnostics.
