A kind of baby bed-wetting alarm device

Abstract

The invention relates to a baby bedwetting alarm device, comprising a bedwetting detection pad arranged on a bed board, a signal processor connected with the bedwetting detection pad, and an alarm indicator connected with the signal processor, wherein the bedwetting detection pad monitors bedwetting in real time and transmits detection information to the signal processor, and the signal processor processes a signal, judges the bedwetting condition and transmits the judgment result to the alarm indicator for indicating; the bedwetting detection pad comprises an air and water permeable layer at the top, a first protective layer below the air and water permeable layer and a flexible sensor below the first protective layer, and a second protective layer and a waterproof and air permeable layer are sequentially arranged below the flexible sensor. By adopting the flexible sensor made of a special material, the device has good adaptability to baby body and high comfortableness, and can accurately judge the bedwetting position when the posture of a baby is changed.

Description

technical field [0001] The invention belongs to the field of automatic detection and provides an automatic device for detecting bedwetting of babies and issuing an alarm. Background technique [0002] With the development of social modernization, parents take care of their babies more and more meticulously. Before the baby learns to speak, the guardian can only judge the baby's state through the baby's facial expression and crying, but the baby's crying is often caused by many reasons, and the guardian cannot directly and effectively judge the baby's crying situation accurately. Determine if bedwetting occurs. [0003] The traditional way of inspection is manual inspection, for example, using hands to inspect or directly observing with eyes, but the above two methods have certain defects. First, the method of manual inspection requires great patience and care from the guardian. To achieve The effect of not wetting the bed requires a high inspection frequency, which increas...

Problems solved by technology

[0006] However, in the actual application environment, it is impossible for the baby to remain still for a long time, and its posture often changes, so the position where the urine wets generally cannot be the same. In addition, the direction and degree of urine flow after the urine is also unpredictable. Therefore, the above two detection and alarm devices using humidity sensitive elements are limited by conditions, and cannot accurately and quickly detect whether the baby wets the bed during actual use, and the installation method and position of the sensitive elements are also likely to cause discomfort to the baby. , in addition, the long-term stability of humidity sensitive components is not enough, and it is easily affected by polluting substances in this working environment, aging problems will occur after long-term use, the accuracy will decrease, and the service life will also be shortened
