In-Depth Review: CARESONO-M2 Portable Bladder Scanner
Bladder dysfunction is a common yet often overlooked clinical challenge, particularly among elderly, post-operative, or neurologically impaired patients. In this context, bladder scanners serve as indispensable tools for measuring bladder volume non-invasively, guiding catheterization decisions, and monitoring urinary retention. One standout device in this category is the CARESONO-M2, a portable ultrasound-based bladder scanner known for its compact form factor and accuracy.
🧠 Technical Specifications & Design
Device Name: CARESONO PadScan M2
Manufacturer: Caresono Technology Co., Ltd.
Imaging Mode: B-mode ultrasound
Screen: 2.5″ color TFT LCD touchscreen
Weight: ~600g (handheld unit only)
Probe: 3D mechanical sector probe, 2.5–3.5 MHz
Battery: Rechargeable lithium-ion, ~3 hours continuous use
Measurement Range: 0 – 999 mL
Memory: TF card support for image/data storage
The M2 is built to be both rugged and lightweight. Its 3D mechanical sector probe captures a volumetric scan of the bladder in a matter of seconds, producing cross-sectional images processed through proprietary algorithms for bladder volume estimation.
🏥 Clinical Applications
The CARESONO-M2 is suitable for a wide range of clinical environments:
1. Urology Clinics
Used for routine assessments of post-void residual (PVR) volume.
Supports early detection of urinary retention, benign prostatic hyperplasia (BPH), or detrusor underactivity.
2. Post-Operative Monitoring
Prevents unnecessary catheterization.
Helps in timely detection of urinary retention post-surgery, especially in orthopedic and gynecological cases.
3. Geriatric & Home Care
Enables nurses or caregivers to assess patients without invasive procedures.
Particularly valuable in monitoring long-term catheter users.
4. Emergency & Critical Care
Provides quick bladder assessments in triage or ICU environments.
Battery-operated design is ideal for use during transport or power outages.
🛠 How It Works: Step-by-Step
Power On: The device boots quickly via the touchscreen interface.
Apply Gel: Ultrasound gel is applied to the lower abdomen (suprapubic region).
Positioning: The probe is held perpendicular to the abdomen.
Scanning: The device emits ultrasound pulses; reflections are used to form a 3D image of the bladder.
Auto Measurement: The built-in algorithm auto-calculates volume based on bladder shape and cross-sectional area.
Save or Print: Scan data is stored on a TF card; it can be printed via optional peripherals.
📊 Accuracy & Limitations
Accuracy: Within ±15% compared to catheterized volume measurements — considered reliable for clinical decision-making.
Limitations:
Accuracy can be affected in patients with abdominal scarring or obesity.
Not intended for high bladder capacities (>999 mL).
Operator training is still essential despite its intuitive UI.
🔋 Battery & Portability
One of the M2’s biggest strengths is portability:
Rechargeable battery supports multiple scans on a single charge (~100 scans).
Charges via standard wall outlet or docking station.
Entire system fits into a small carry case for mobile diagnostics.
🧾 Cost & Value
Price Range (2024): ~$4,000 to $6,000 USD, depending on supplier and region.
What’s included:
Scanner unit
Charging dock
Ultrasound gel
User manual and quick start guide
Warranty (usually 1–2 years)
The M2 offers an excellent return on investment, especially for outpatient clinics and home health providers, by reducing catheterization, minimizing UTI risk, and streamlining patient workflows.
