Indications for Use

The BladderScan® Prime system is an ultrasound device intended to be used for measuring the urine volume in the bladder non-invasively.

Device Story

BladderScan Prime is a portable, battery-powered ultrasound device for non-invasive bladder volume measurement. It utilizes a mechanical sector probe (13 mm diameter, 2.95 MHz resonant frequency) to capture 3D ultrasound data. The system employs patented NeuralHarmonics technology to process 12 scan planes, transforming ultrasound signals into a 3D bladder image and volume calculation. Operated by physicians or medical professionals, the device provides real-time feedback, directional aiming, and volume results on an integrated LCD touchscreen. It features selectable patient orientation and live scan imaging. The output assists clinicians in assessing bladder volume, aiding in clinical decision-making regarding urinary management. The device is intended for use in clinical settings.

Clinical Evidence

Bench testing only. No clinical data provided. Evaluation included electrical, thermal, mechanical, and EMC safety testing, cleaning/disinfection validation, and biocompatibility testing per ISO 10993 standards. Acoustic output was measured per AIUM/NEMA standards. Performance was verified through design reviews, risk assessments, and hardware/software verification.

Technological Characteristics

Mechanical sector probe; 2.95 MHz resonant frequency; 2.49/1.72 MHz nominal acoustic output frequencies; 120-degree sector angle; 12 scan planes. Patient contact material: Lexan Polycarbonate Plastic HP1-1H112. Power: Lithium-ion battery. Connectivity: USB, SD card. Standards: IEC 60601-1, IEC 60601-2-37, IEC 60601-1-2, ISO 10993, ISO 13485.

Indications for Use

Indicated for non-invasive measurement of urine volume in the bladder for male, female, and pediatric patients. Contraindicated for fetal use, pregnant patients, patients with ascites, or patients with open skin or wounds in the suprapubic region.

Regulatory Classification

Identification

The BladderScan" Prime system instrument provides noninvasive measurement of urinary bladder volume. The instrument calculates the bladder volume using patented NeuralHarmonics technology, which is easy to use and comfortable for the patient. Volume measurements made with NeuralHarmonics are accurate than those from conventional two-dimensional ultrasound as they are based on a more complex, three-dimensional image of the bladder.

Bladder volume, mode (male, female and small child), directional aiming with real-time feedback, battery status and usage rate indicators are displayed on the LCD display. The system also includes a battery charger for custom, user-replaceable lithium-ion batteries included with the system,

#### 5. Intended Use:

The BladderScan "Prime system is an ultrasound device intended to be used for measuring the urine volume in the bladder non-invasively.

Clinical Application: Abdominal B-Mode (Bladder)

#### 6. Technological Characteristics:

The BladderScan" Prime system and BladderScan" BVI 9400 system are both Track 1 devices that employ the same fundamental technology. The comparison table is provided below.
