A flange for a medical collecting bag having an aperture allowing bodily fluids or exudates to enter the bag. The flange has an inner rim delimiting the aperture therein, and a central area encircling the aperture, which area has a predetermined weakening line pattern. The force needed for removing the bag flange from the skin or a body side member is smaller than the force needed for breaking the weakening lines which enables a simple gradual enlargement of the aperture of an ostomy device for adaptation of the aperture to the size of the stoma or for adaptation of the aperture to the size of a wound, as well as a complete removal of the bag flange when substituting the bag.

A current sensor 73 detects a current flowing through a first buss bar 11. When a current value detected by the current sensor 73 became equal to or greater than a threshold current value, a CPU 74 outputs a driving control signal to a driving circuit 77, and the driving circuit 77 operates an, ignitor 29 through a second substrate 65 and a terminal 50. Therefore, the ignitor 29 ignites, a second projection 41 is melted by heat of a heating agent 27, a compression spring 34 is expanded and a thermite case 26 jumps up. Thus, electrical connection between the thermite case 26 and the first and second buss bars 11, 19 is interrupted. Further, since an outer container 61 in which the current sensor 73, the CPU and the driving circuit 77 are accommodated is integrally assembled with the cap 14a and the resin case 14b in which the thermite case 26, the ignitor 29, the compression spring 34 and the second projection 41 are accommodated, non-operational state of the ignitor 29 due to disconnection of electric wire is not generated.

An anti-fuse useful in implementing redundancy in a memory utilizes a normal transistor characteristic that is generally considered undesirable in order to provide two easily detected states. The un-programmed state, which is the high impedance state, is achieved simply with a normal transistor in its non-conductive state. The programmed state, which is the low impedance state, is achieved by forcing a normal transistor to conduct current through its gate. This causes the gate dielectric to become permanently conductive. This programmed transistor then is conductive between its source and drain that is easily differentiated from the transistor that is held in its non-conductive state. The result is a fuse technology using an anti-fuse that provides for easily distinguishable programmed and un-programmed states achieved by electrical programming rather than by laser programming.
