Title
(EN) SYSTEMS AND METHODS FOR REAL TIME NONINVASIVE URINE OUTPUT ASSESSMENT
(FR) SYSTÈMES ET PROCÉDÉS D'ÉVALUATION NON INVASIVE EN TEMPS RÉEL DE SORTIE D'URINE
Abstract
(EN) The present disclosure discloses systems and methods for measuring the bladder volume of a patient. An ultrasound transducer array may be used to transmit electrical pulses and receive the backscattered pulses that can be analyzed to develop a representation of the patient's bladder. The backscattered ultrasound signals may be amplified, converted, and processed by circuitry and computer software to develop an axial position of the anterior and posterior bladder walls. Bladder volume measurements derived from the patient's bladder may then be wirelessly transmitted to a display device for assessment by a healthcare provider. The ultrasound transducer array portion of the device may be held in place between the patient's peritoneum and pubis by an elastic strap or a belt to ensure proper positioning.
(FR) La présente divulgation divulgue des systèmes et des procédés pour mesurer le volume de la vessie d'un patient. Un réseau de transducteurs à ultrasons peut être utilisé pour transmettre des impulsions électriques et recevoir les impulsions rétrodiffusées qui peuvent être analysées pour développer une représentation de la vessie du patient. Les signaux à ultrasons rétrodiffusés peuvent être amplifiés, convertis et traités par des circuits et un logiciel informatique pour développer une position axiale des parois de la vessie antérieure et postérieure. Des mesures de volume de vessie dérivées de la vessie du patient peuvent ensuite être transmises sans fil à un dispositif d'affichage en vue d'une évaluation par un fournisseur de soins de santé. La partie réseau de transducteurs à ultrasons du dispositif peut être maintenue en place entre le péritoine et le pubis du patient par une sangle élastique ou une ceinture pour assurer un positionnement correct.
