ODSSY — a portable fluid management system for critical care.

ODSSY is a portable infusion platform for battlefield trauma and emergency medicine. It processes an available water source, works with concentrated plasma and medication cartridges, and prepares and administers controlled volume replacement at the treatment site. We developed the embedded control system, the dose and flow control and the operator interface, and integrated them with the fluid hardware.

01 / The brief

Critical fluid delivery without the usual logistics.

ODSSY was designed around one field requirement: cut the equipment and preparation needed to give immediate fluid replacement in remote or emergency conditions.

Water is usually the one input already available at the scene. The system uses it as the base fluid and combines it with concentrated plasma and medication cartridges to make up what is needed on site.

Filtration, fluid handling, cartridge management, dose and flow control, and operator interaction all had to sit inside one portable embedded system.

02 / The problem

A clinical workflow compressed into one device.

Field treatment can mean carrying separate fluid bags, tubing and medication supplies to the casualty and assembling them by hand at the point of care.

ODSSY moves those functions into one controlled platform. The operator selects the workflow on the touchscreen while the embedded system coordinates the fluid paths, the delivery hardware and the cartridge functions underneath.

The engineering problem is holding precise, repeatable control across several fluid operations while keeping the interaction simple enough to use under field conditions, by an operator with a casualty in front of them.

03 / What we did

One embedded system was developed as the centre of the device, coordinating the operator interface, the delivery hardware, the fluid states and the sequences that carry the device from preparation through to infusion.

01Embedded control system — Custom embedded control software, developed for this device, runs it and holds its state. The touchscreen interface, the delivery hardware, the fluid paths and the operating sequences are coordinated from one place. 02Dose and flow control — The delivery hardware meters fluid through the device’s fluid paths. The control system sets flow rate and delivered volume, and holds them within the operating limits each stage of the process requires. 03Water and fluid processing — The system accepts an available water source and processes it for use in the delivery workflow, so prepared fluid volumes do not have to be carried to the treatment site. 04Cartridge based treatment — Concentrated plasma and medication cartridges give the fluid system a compact input format. Cartridge selection and placement are built into the device workflow instead of sitting outside it as a manual step. 05Operator interface — A 7 inch touchscreen is the primary operating interface: patient parameters, fluid and medication selection, process controls and device status. 06Reconstitution and infusion — The device coordinates reconstitution, line preparation and controlled infusion across separate fluid paths, so prepared contents can be introduced into the delivery stream at the selected rate.

Fluid management

Multiple fluid operations. One embedded system.

Water processing, cartridge preparation, line management and controlled infusion coordinated through the same embedded control architecture.

Operator interface

The complete workflow at the point of care.

Patient definition, fluid and medication selection and delivery are worked through on the same screen, with device status visible at each step.

04 / Where it stands

From field logistics to a controlled fluid platform.

Before

Separate fluids, medication supplies and manual preparation at the treatment site.

After

A portable platform combining water processing, cartridge based inputs, precision fluid control and embedded operator interaction.

Further development, testing and validation towards the intended emergency and field applications.
