Mother-son type urine collection bag acousto-optic alarm apparatus

The invention relates to a mother-son type urine collection bag acousto-optic alarm apparatus. A circuit board and a power supply module are installed at the upper surface of a housing, and an infrared light emitting diode and a photosensitive diode are oppositely linearly placed at the two sides of a mother-son type urine collection bag for detecting whether the mother-son type urine collection bag fully collects urine; and the infrared light emitting diode and the photosensitive diode are connected with a single-chip microcomputer system in the circuit board, the single-chip microcomputer system is connected with a buzzer for giving an alarm after the mother-son type urine collection bag fully collects the urine. According to the invention, the phenomena that a conventional mother-son type urine collection bag cannot be individually used and cannot automatically report full urine collection are changed, and the mother-son type urine collection bag acousto-optic alarm apparatus can be used simply by switching on a switch on the housing according to the operation method of the conventional urine collection bag during application. A non-contact detection unit automatically detects whether the urine is fully collected and gives the alarm about a prompt of changing the urine bag in case of the full collection. For improving the application comfort, the apparatus also has a false alarm removal function and a function of automatically stopping the alarm after the alarm is given for 30 seconds so as to realize intelligent alarm.
