Catamenial device change indicator
View Patent ↗An absorbent device for insertion into a vaginal cavity, the absorbent device having an absorbent body and an indicator structure arranged and configured within the absorbent body, the indicator structure having a resilient member maintained in a strained configuration by a restraint; wherein the resilient member is capable of reverting to a relaxed configuration upon the weakening of the restraint and the restraint weakens upon exposure to moisture.
1. A method of absorbing aqueous vaginal fluids comprising the steps of:
a) inserting a first absorbent device into a vaginal cavity, the absorbent device comprising an absorbent body and an indicator structure arranged and configured within the absorbent body, the indicator structure comprising a resilient member maintained in a strained configuration by a restraint; wherein the resilient member is capable of reverting to a relaxed configuration upon the weakening of the restraint and the restraint weakens upon exposure to moisture
b) allowing the first absorbent device to absorb sufficient aqueous vaginal fluids to weaken the restraint and to permit the resilient member to revert to the relaxed configuration;
c) detecting changed dimensions of the first absorbent device caused by the reversion of the resilient member to the relaxed configuration, while inserted; and
d) removing the first absorbent device from the vaginal cavity.
2. The method of claim 1 further comprising the step of inserting a second absorbent device into the vaginal cavity after the step of removing the first absorbent device from the vaginal cavity.
