Description

Diapers capable of detecting feces and urine}

The present invention relates to a urine-sensing diaper, and more particularly, to a urine-sensing diaper capable of preventing unnecessary diaper change due to frequent urination and greatly improving convenience.

In general, infants or patients with mobility difficulties who are unable to self-dispose of feces due to defecation or urine due to urination wear diapers, and diapers used for toileting or diapers used for urination are collected and processed by guardians. At this time, if the diaper is not replaced within a short time after going to the toilet, it causes skin troubles due to excretion, so prompt replacement is required.

Therefore, the guardian of the wearer who wears a diaper frequently checks the presence or absence of excretion using the sense of smell and sight, which is inconvenient. There was a problem.

In order to solve this problem, research and development are being conducted on a urine detection diaper that detects the wearer's defecation state and alerts the guardian when urine is detected.

However, the conventional feces and urine detection diaper 100 detects moisture absorption in the diaper body 110 and generates an alarm immediately. However, when a small amount of urine is frequently urinated, the alarm is repeatedly generated at a short cycle, so that the diaper replacement time There was a problem that the inconvenience of the caregiver increased as the length of the screen was unnecessarily shortened.

In addition, the conventional feces and urine detection diaper 100 is not only aesthetically unsightly as the terminal 130 is exposed on the surface of the diaper body 110 in order to connect the detection line 120 and the control unit (not shown), but also distributes the diaper. In the process, the terminal part 130 exposed to the outside is oxidized by external moisture, etc., and there is a problem in that the urine detection function is deteriorated.

In addition, when the diaper wearer moves while wearing the diaper, the connection portion between the control unit (not shown) and the terminal unit 130 is short-circuited or the current change amount is not constant as it flows, so there is a problem in that the reliability of urine detection is greatly reduced.
