The Compact Disposable Unit can be easily moved from one Warrior configuration to the next so as to facilitate a complete continuum of care implementation and by that simplify patient’s handoff between settings and reduce the overall cost of ownership (fewer consumables).
Superior Performance is Delivered at Utmost Safety and an Affordable Price!
The Compact Disposable Unit (CDU) is where the warming ‘magic’ takes place. After connecting CDU to the Blood/IV bag and to the Base Unit (either directly or with an extension cable) and flushing the air out, near freezing blood/IV fluids will get warmed to body temperature in a few seconds, even at very high resuscitation rates.
The fluid path is aluminum-free. It is composed of a 220 cm / 7.2 ft medical grade stainless steel coil and PVC tubing (together, 19 ml priming volume). Temperature sensors are attached along the fluid path. All these components are packaged in an EPP casing, which is not only robust, affordable and light-weight, but it also acts as a great isolation material.
The sensors communicate the blood/IV fluids temperature to the Base Units a few hundred times per second. Based on these readings, the Base Unit continuously assesses whether to increase, decrease, or keep the warming level intact so as to secure 38°C output (±2°C). The CDU can sustain immense pressure; based on a third party testing, the CDU was able to sustain 175 PSI; that is, 25 fold the requirements of the standard! This pressure handling capability along with the comfortable amount of priming volume, real-time sensing, utmost heat transfer efficiency, and sufficient battery capacity, allow the QinFlow Blood Warmer to outperform other solutions when intense and intermittent bolus flows are applied (e.g. through methods such as hand pump, syringe, or LifeFlow like devices).
There are a few additional benefits related to the CDU’s design, for example:
- Undisrupted Fluid Path: The CDU’s fluid path is undisrupted in the sense that it has the same diameter as your line, and it has very smooth curves. This design ensures minimal structural impact on the flow (such as abrupt turns, connection points, flow changes, etc.) which is then translated into low sheer force, minimal turbulences, no cavitation, and no air bubble formation, to name just a few benefits.
- Incremental Heat Transfer: With 4150 mm^2 warming surface, the CDU has one of the most relaxed heat transfer processes in the industry.
- Designed to Not Exceed 38°C: Unlike most warming technologies, and due to its extremely high efficiency, the CDU’s heating element is designed to not exceed 38°C.
- No Heating Inertia: Once the heating stops, the heating element cools down immediately.
- Aluminum Free: By using common warming elements (i.e. medical grade stainless steel coil), we were able to eliminate toxicity concerns that may be traced for example in aluminum warmers.
- Designed for Manufacturability: Due to the simple implementation of the underlying technology, the CDU availability is unlikely to be impacted by surge in demand or sudden supply constraints.
- Designed for Cost: The CDU design facilitates the lowest consumable cost among all modern battery operated warmers.
- Finally, the CDU technology has been perfected over many thousands of field utilizations.
