The night’s balance is already there.
The incoming nurse sees a continuous record of input and output through the night, without having to reconstruct it from a paper chart or wait for someone else’s summary.
UK medtech · Class IIa device in development
Continuous fluid balance,
without the paperwork.
FlowMaster 1.0 turns fluid intake and output into a real-time, automatically captured signal — surfaced at the patient and in the EPR, so clinicians can see what is actually happening and act sooner.

01 · The problem
Fluid mismanagement is one of the largest, quietest sources
of preventable harm in modern hospitals.
Almost every hospital inpatient receives intravenous fluids at some point during their stay. Getting the balance right is fundamental to safe care — and yet, in routine UK practice, fluid status is still tracked on paper or in fragmented charts that nobody can rely on in real time.
When fluid management goes wrong, the consequences are quiet but serious: acute kidney injury, pulmonary oedema, prolonged stays, and avoidable deterioration. The evidence has been consistent for more than two decades.

02 · Current practice
A monitoring task that has outgrown the paper chart.
Today’s fluid balance is reconstructed by hand: nurses move between several inputs and outputs, totting up volumes from memory or from notes that nobody else can see for hours. The information clinicians need to act on is almost always lagging the patient.
-
01 · Input
Multiple inputs
IV infusions, oral intake, drug diluents, flushes, blood products and enteral feeds — each typically recorded in a different place, on a different cadence.
-
02 · Output
Multiple outputs
Urine, drains, stoma, vomit, blood loss and insensible losses — measured by hand where possible, estimated where not, and prone to being missed entirely.
-
03 · Recording
Manual recording
Numbers are written onto a paper chart, usually hours after the event, re-entered into the patient record later, and almost never reconciled between the two in real time.
-
04 · Visibility
Delayed visibility
By the time a clinician reviews fluid balance, the picture is already several hours old. Clinical deterioration that the trend would have shown is seen too late, or seen by someone else.
None of this is a failure of clinical staff. It is a tooling problem: the fluid balance chart was designed for a different era of care, and it has not changed in any meaningful way in decades.
03 · FlowMaster 1.0
One signal, continuously, wherever care happens.
FlowMaster captures fluid intake and output directly at the patient, derives a single, continuously updated balance, and surfaces it both at the patient and in the EPR — so anyone caring for that patient can see and trust the same number.
-
Sensors at the source
Disposable per-patient sensors sit on the IV line and on the output route. Volumes are measured directly, not estimated, and not retrospectively typed in.
-
One number everyone agrees on
Intake and output are reconciled in software, so the live display, the chart and the EPR show the same continuous figure.
-
Built around clinical workflow
FlowMaster is being designed to fit existing nursing and ward-round routines — not to replace them, and not to require a separate logon during a busy shift.
-
Designed to integrate with EPR systems
Designed for integration into existing electronic patient record (EPR) systems such as Epic and Oracle Cerner, so the live balance flows into the same record the rest of the team is already working from.
FlowMaster 1.0 is a device in development. Functionality described here reflects design intent and is being evaluated through formal verification, validation and clinical investigation. It is not yet UKCA or CE marked.
04 · In practice
A shift, with FlowMaster in the loop.
FlowMaster is designed around how a real ward actually runs — the handover, the ward round, the night shift, the deteriorating patient. The product points below describe the intended day-to-day experience.
10:00 · Ward round
One number, agreed across the team.
The team reviews the live balance together, on the same display, instead of three people looking at three slightly different versions of the chart.
14:20 · Subtle deterioration
The trend is visible before the alarm.
Output drifts down over a few hours. The trend appears live on the patient’s FlowMaster display and in the EPR, so review and escalation can happen earlier in the deterioration curve, not later.
22:00 · Night cover
No reconstructions at midnight.
On-call staff can see fluid status for any monitored patient without paging a colleague or unpicking a paper chart that may not have been updated since lunchtime.
05 · Development roadmap
From a working bench model to clinical deployment.
FlowMaster is being developed against a Class IIa pathway, scoped to UK regulatory expectations. Stage labels are illustrative; durations are not commitments and remain subject to funding, evidence, regulatory feedback and clinical partnership.
-
Stage 1
Bench model & alpha funding
Core measurement principles demonstrated on a working bench model. Seeking funding to build the first alpha prototype.
We are here -
Stage 2
Verification & regulatory preparation
Alpha build, engineering verification, ISO 13485 quality system and technical file under development.
-
Stage 3
Clinical investigation
Observational and pilot clinical work to support the technical file.
-
Stage 4
Manufacturing & supply readiness
Design transfer, supplier qualification and pilot-scale production.
-
Stage 5
UKCA / CE marking and launch
Regulatory submission, conformity assessment, and first commercial deployments.
06 · The company
A clinician-engineer founding team, supported by senior advisors.
FlowSync Solutions Ltd is a UK medtech company building FlowMaster. The founders bring direct critical-care and chartered-engineering experience, and work with a small group of senior clinical and commercial advisors. The company has filed IP covering FlowMaster’s core measurement approach, including two novel embodiments, and has carried out preliminary freedom-to-operate work — led by Dehns — to establish a clear technical position. A full FTO search has not yet been commissioned; further detail is shared under confidentiality.

08 · Investors & contact
SEIS & EIS Advance Assurance secured — raising for the alpha build.
FlowSync Solutions Ltd has HMRC SEIS and EIS Advance Assurance in place. We are raising to deliver the first alpha prototype, complete engineering verification and progress the regulatory file. Detailed materials are shared with qualified investors under NDA.
- Funding stage
- SEIS / EIS Advance Assurance secured. Round terms, financial model and work-package detail are shared under NDA on request.
- Market context
- Around 17 million hospital admissions per year in the UK, the majority receiving IV fluids at some point. NICE estimates approximately 1 in 5 patients on IV fluids experience complications from inappropriate administration — a large, durable problem with no incumbent digital standard.
- Commercial model
- A durable patient-side unit with EPR integration, disposable per-patient sensors and an associated software layer — designed to fit hospital procurement structures rather than direct-to-consumer growth dynamics.
- Regulatory profile
- FlowMaster is being developed against a UKCA / CE Class IIa pathway, with specialist regulatory guidance from SOTAS and an ISO 13485 quality management system in build.
