Device, system and method for urinary bladder fullness indicator

A bladder volume detection device (100), the device comprising:

• a) a housing (101) configured for placement along an abdominal surface respective of the urinary bladder so as to allow for measuring the volume of the urinary bladder;
• said housing comprising an electronics module (110) including a processor (112), an acoustic transmitter (102) and at least one receiver (104), said housing characterized in that said acoustic transmitter (102) and said at least one receiver (104) are disposed therein in a manner wherein said transmitter (102) is disposed adjacent to an external surface of said housing and configured to be disposed proximal to or along the abdominal surface and wherein said at least one receiver (104) is disposed distally to said transmitter (102), and is forming an open space (106) between said transmitter (102) and said at least one receiver (104);
• wherein said receiver (104) is configured not to be directly coupled to the abdominal surface is configured to be at a distance at least equal to a vertical dimension of said open space;
• said device is further characterized in that said open space (106) has a vertical dimension of at least 0.1 mm and up to 20 mm;
• b) said transmitter (102) comprising a piezoelectric element configured to receive a pulse from said electronics module so as to generate a resonant frequency of up to 20 kHz utilized to ping the urinary bladder and wherein said at least one receiver (104) is configured to receive a return signal (104s) from the urinary bladder;
• c) said processor (112) configured to undertake processing of said return (104s) to determine the urinary bladder volume.
