Defecation/urination detection system and method

Abstract

The present invention relates to detection of defecation / urination of human bodies. In particular, the present invention provides a defecation / urination detection system and method using an RFID passive tag and a reader to measure a change in the sensitivity (or receiving count) of the tag and then inform a user of the incidence in real time mode. The defecation / urination detection system comprises: a first step of registering a defecation / urination detection tag in one-to-one correspondence upon receiving a request for registration of the defecation / urination detection tag, following the initiation; a second step of detecting an energy level of a received signal that is generated from the registered defecation / urination detection tag, thereby detecting sensitivity based on the energy level; and a third step of analyzing the detected sensitivity and then making an alarm sound and a display if there is a change in the sensitivity of the defecation / urination detection tag due to defecation / urination, regarding the change as a criterion for determination of the incidence of defecation / urination.

Description

technical field [0001] The present invention relates to defecation / urination detection, more specifically, to a defecation / urination detection system and method. When detecting human defecation / urination, the RFID method is used to detect the state of defecation / urination, and then the user is notified of the detection result. Background technique [0002] Usually, people who cannot recognize defecation / urination or cannot manage defecation / urination independently, such as infants, elderly people with dementia, and critically ill patients who cannot move freely, will be faced with the situation of dealing with excretion with the help of guardians or caregivers. Therefore, guardians or caregivers deal with excrement by putting on diapers or underwear for infants, demented elderly or critically ill patients, etc., frequently checking for defecation / urination, and replacing diapers or underwear. [0003] In this case, in order to determine whether defecation and urination have ...

AI Technical Summary

Problems solved by technology

[0005] However, in a ward where there are many patients, the conventional technology suffers from the inconvenience of assigning an ID unique number to each tag in order to identify each patient or newly assigning an ID when each tag is replaced, and because it contains a low-power battery, the In the case where the patient does not defecate / urinate for a long time, there is a disadvantage of detection error due to battery consumption

[0006] In addition, when an active tag containing a battery is frequently used in a disposable manner, the active tag containing a battery has a disadvantage of being costly due to an increase in product cost

[0007] In addition, although, as another conventional technology, a diaper equipped with a sensor for detecting defecation / urination and capable of issuing an alarm when defecation / urination is detected is developed so that the disposable diaper is provided with an alarm generating device, so that it has the disadvantages of enduring the inconvenience of adhering the device to the human body, increased manufacturing cost and complicated processing
