Bladder Volume Instrument (M1 & M1-W)

Description

The Bladder Volume Instrument (M1 & M1-W) is a non-invasive ultrasound device engineered to deliver quick and accurate bladder volume measurements. Designed for use in a variety of clinical environments such as hospitals, outpatient clinics, and care homes, it supports clinicians in detecting urinary retention and making informed catheterisation decisions. This device enhances patient care, reduces infection risks, and supports a more efficient workflow.

 

Medical Process Explanation

Clinical Use Case

When a patient shows signs of urinary retention or needs post-void residual assessment, a healthcare professional can use the Bladder Volume Instrument to scan the bladder region. The device provides real-time 3D ultrasound imaging and automatically calculates bladder volume in millilitres (mL), enabling timely and accurate clinical decisions.

Steps Performed by the Healthcare Professional

1. Positioning the Patient: Lay the patient flat on their back (supine position).
2. Preparation: Apply ultrasound gel to the lower abdomen.
3. Scanning: Position the probe above the pubic bone and start the scan.
4. Volume Calculation: The device automatically captures images and displays bladder volume.
5. Post-Scan Action: Based on the volume, clinicians decide on further steps like catheterisation or monitoring.
