Silverline – Digital Innovation
in chest drainage monitoring

Drentech SilverLine

This device represents an innovation in post-surgical chest drainage monitoring: an intelligent device that transforms the management of pleural drains through pressure sensors, digital flowmeters, and Bluetooth connectivity for real-time data on fluid loss, air leaks, and intrapleural pressure.

SilverLine Technology

Continuously monitors with sampling every 5 seconds, IP22D certification, and an encrypted BLE 5.1 protocol. The precision of its measurements enables early identification of complications such as occlusions or persistent air leaks.

SilverLine Mobile App

The mobile app turns the smartphone into a monitoring hub: real-time visualization, trend analysis, and critical alerts. It supports multi-device management for surgical departments and CSV export for direct integration with the electronic medical record, eliminating manual transcription.

Context & Challenge

With Drentech hardware already certified and market-ready, the main challenge lay in creating a software ecosystem that could transform complex technical data into actionable clinical information. Problem analysis revealed three interconnected critical dimensions.

01 Clinical Challenge

From manual monitoring to secure digitization

The key issue was transitioning from manual measurements every 4–6 hours to continuous digital workflows while preserving operational simplicity. We implemented multi-level alerts with customizable thresholds and hysteresis to prevent false alarms.

02 Usability Challenge

Interface for high-pressure settings

We designed a dashboard capable of managing up to 10 patients. Bluetooth pairing with pre-printed PINs and automatic association storage was implemented.

03 Technical Challenge

Reliability in harsh environments

Bluetooth stack with automatic retries and offline buffering for the electromagnetically complex environments of surgical rooms. SQLite database with SQLCipher encryption for privacy and forensic tracking. Selective CSV exports compatible with major electronic medical record systems."

Goal

The app was not meant to be just a data "viewer," but a true digital clinical assistant capable of:

01.

Simplifying nursing workflow without disrupting it

02.

Ensuring safety through intelligent and reliable alerts

03.

Automatically documenting for compliance and audit

04.

Scaling from single patient to entire ward

05.

Adapting from hospital settings to home care

Technological Proposal

Given the hardware was already completed, our work focused on:

Multi-platform clinical app:

  • Interface optimized for one-handed use during procedures
  • Real-time dashboard with immediate visual indicators
  • Multi-device support for ward management
  • Automatic CSV export for clinical record integration

Robust and secure architecture:

  • BLE 5.1 connectivity with automatic retries
  • Offline buffer for continuity in case of disconnection

Achieved Results

Elimination of manual transcription errors

Improved surgeon-nurse communication with shared data

Safer discharges with continuous home monitoring

History easily viewable and exportable

Important alarms and information always at hand

The difference of a partner specialized in digital healthcare

In the healthcare sector, selecting the right technology partner can determine the success or failure of a digital innovation. Airbag Studio stands out in the Italian and European landscape for a unique mix of expertise, methodologies, and tangible results that make the company the ideal partner for successful healthcare projects.

Design Thinking applied specifically to the healthcare sector

While many agencies apply generic methodologies, Airbag Studio has developed a Design Thinking approach specific to healthcare, documented and refined over years of experience. The company understands that, in healthcare, users only invest time in new digital tools if they clearly solve real problems. Their process always starts from direct dialogue with patients, doctors, nurses, and caregivers, generating solutions that address real everyday challenges rather than perceived issues.

Proven track record with medical device industry leaders

The credibility of Airbag Studio is demonstrated by successful collaborations with industry-leading medical device companies. Empatica, a pioneer in health monitoring wearables, chose Airbag for the design of its mobile applications, praising "the expertise and experience that led to a refined design and quality user experience." Amiko, specialized in solutions for respiratory therapy management, entrusted Airbag with the development of version 2.0 of its Respiro app, highlighting the company's ability to focus on the patient experience while following the latest native mobile development guidelines.

Specific technical expertise for healthcare innovation

Airbag Studio is not just an app development agency but a center of excellence for healthcare-critical technologies. The team is proficient in Bluetooth integration with medical devices, telemedicine systems development, and integration with wearables and activity trackers. This specialized technical expertise drastically reduces project risks and accelerates the time-to-market for innovative solutions.

Structured methodology that accelerates innovation

Airbag Studio's 6-phase process (Kickoff, Definition, Implementation, Execution, Control, Closure) has been specifically optimized to make "the journey from idea to market launch linear, short, and efficient." In a sector where delays in innovation can mean lost lives or missed opportunities, Airbag's ability to accelerate development while maintaining high quality standards is a crucial competitive advantage.

Multidisciplinary team that understands healthcare complexity

The Airbag team brings together designers, developers, strategists, and problem solvers in a truly multidisciplinary approach. This diversity of expertise is essential in healthcare, where solutions must balance clinical requirements, user needs, regulatory constraints, and technological innovation. The ability to "design complex applications that work in the simplest way possible" is especially critical in healthcare, where users often operate under stress or in emergency situations.

Commitment to social innovation and well-being

Airbag Studio explicitly declares its commitment to "investing and dedicating more and more time to the development of apps for health, well-being, and social innovation." This corporate mission aligned with healthcare sector goals means that clients get more than a supplier—they get a partner genuinely interested in the long-term success of the solutions developed.
