FLUID SYSTEM COMPRISING A SAFETY DEVICE
First Claim
Patent Images
1. A fluid system for a fluid, comprising:
- a first support plate and a second support plate, at least one of the first support plate and the second support plate having an inner face including a flow system formed as depressions in the inner face, the flow system comprising an inlet, an outlet and at least one fluid line extending from the inlet to the outlet;
an electrical current supply device; and
a meltable component comprising a film positioned between the first and second support plates such that it extends over at least a portion of the inner face and beyond the fluid line, and an electrical conductor integral with the film, whereinthe electrical conductor is electrically coupled to the electrical current supply device, andthe meltable component is positioned with respect to the at least one fluid line such that electrical current passing through the electrical conductor melts the meltable component thereby causing a flow of the fluid through the flow system to be interrupted, stopped or diverted.

Abstract
A fluid system that includes a flow system for a liquid having an inlet, an outlet, at least one fluid line extending from the inlet to the outlet and an electrically activatable melting device, wherein activation of the melting device causes melting, which interrupts, stops or diverts a flow of the fluid through the flow system. In one embodiment, the fluid system may be used in a device for measuring blood sugar.

25. A fluid system for a fluid, comprising:
-
a first support plate and a second support plate. at least one of the first support plate and the second support plate having an inner face including a flow system for transporting the fluid, the flow system being formed as depressions in the inner surface, the flow system comprising; an inlet; an outlet; and at least one fluid line extending from the inlet to the outlet;
an electrical current supply device; anda meltable component comprising a film and an electrical conductor, the film positioned between the first and second support plates such that it extends over at least a portion of the inner face and beyond the fluid line, wherein the electrical conductor is electrically coupled to the electrical current supply, and is modifiable from an initial state, in which measurement fluid flows through the fluid line flows, and an activated state, in which the electrical conductor melts a portion of the film thereby diverting the fluid away from the outlet. - View Dependent Claims (26)
