SYSTEM FOR DETECTING AND MONITORING BODY EXCRETIONS USING GAS RELEASING SUBSTANCE INTENDED FOR INTERACTIVE INUREMENT TO TOILET Russian patent published in 2017 - IPC A61F13/42 A61F13/49 A61F13/15 G08B21/20 

FIELD: medical equipment.

SUBSTANCE: system for detection and monitoring of body excretions is disclosed. It comprises absorbent product and first gas releasing substance able to release first gas at first contact of absorbent product with liquid impurities. Wherein system additionally comprises second gas releasing substance able to release second gas, when absorbent product is close to state of maximum saturation. Wherein system comprises at least one device associated with absorbent article comprising at least two gas sensitive compositions and capable of changing its appearance in first way, when contacting with first gas, and in second way, when contacting with second gas. Signalling device is also disclosed. It comprises at least one gas sensitive composition. Signalling device can be changed by contact with gas, released by substance located in absorbent product releasing gas as a result of contact of absorbent product with liquid impurities. Besides, it comprises contact-free gas sensor configured to monitor concentration levels of at least one gas, and controller configured to detect changes in area above limit concentration of at least one gas as a result of contact of absorbent product with liquid impurities and with possibility of continuous monitoring of location of absorbent product in dry condition. Wherein signalling device is able to notify user of absorbent article and/or caregiver on presence of liquid impurities in absorbent product, on degree of saturation of absorbent product and on duration of period, during which absorbent product was continuously in dry state.

EFFECT: method of transmitting information to user of absorbent article and/or caregiver based on operation of signalling device is also disclosed.
