Wearable Ultrasound
Ultrasound worn on the body. The B1 packs three phased-array probes into a housing the size of a matchbox; attach it to the lower abdomen and it scans the bladder continuously and calculates urine volume automatically — patients no longer wait for a nurse to come and measure, and nursing staff no longer make repeated rounds.

Where it is used
- Nursing and ICU: real-time urine output monitoring for patients with an indwelling catheter.
- Elderly, post-operative and post-anaesthesia care: alerts for incontinence and urinary retention risk.
- Rehabilitation and long-term care: observation and nursing support for voiding function.
How it works
Three multi-element phased-array probes on the underside scan the bladder from different angles; the images are fused into a three-dimensional view from which volume is calculated. Attach it to the lower abdomen, pair it with a phone over Bluetooth and set a volume threshold — when the bladder passes that threshold the unit beeps and pushes an alert to the phone. A workstation can receive alerts from several patients at once.
- Small and light: matchbox sized, approx. 45 g.
- All-day monitoring: approx. 26 hours of scanning, approx. 4 hours to charge.
- No repeated handling: once attached it scans continuously and calculates volume automatically.

Who it suits
- Hospital departments: ICU, anaesthesia and post-anaesthesia recovery, geriatrics, rehabilitation — anywhere urine output has to be watched continuously.
- Long-term care and nursing homes: observation of voiding function and nursing support for immobile or incontinent patients.
- Primary care and community settings: follow-up observation where retention is a risk.
How it differs from our other ultrasound ranges
The wearable range is the "attached to the body, monitored continuously" form factor, and it does not replace the other ranges: Handheld Ultrasound is held in the hand and scans on demand; Portable and Trolley Ultrasound have their own displays and suit routine examinations in consulting rooms and wards; Bladder Ultrasound (the BProbe range) also measures urine volume, but a clinician holds the probe and takes a reading, whereas the device in this section is attached and monitors continuously. Selection starts with one question: measure once, or watch continuously?
Common purchasing questions
Q: How is it used?
A: Attach it to the lower abdomen, pair it with a phone over Bluetooth and set a volume threshold; the device scans the bladder continuously and calculates volume automatically.
Q: Do staff have to walk round to each patient?
A: No. The phone connects to a workstation, and alerts from several patients arrive together.
Q: Is it accurate in different positions?
A: Volume is calculated from a three-dimensional reconstruction, and the documentation states that it can be measured in different positions. The applicable scope is that stated in the product registration certificate.
The information on this page is a technical reference based on product specifications; the applicable scope is that stated in the product registration certificate. Contraindications and precautions are set out in the product manual, and the device must be operated by a licensed physician holding the relevant qualifications. Nothing on this page constitutes a claim of clinical efficacy.
