Taking a low cost\/high volume trauma device from a 3D printed prototype to an injection molded product<\/h2>\n

Our client, ACT Medical<\/a>, is developing a novel device that aims to help first responders stem the bleeding from deep trauma wounds, such as knife or bullet wounds. When ACT Medical initially came to Sanner, they had a prototype device utilizing their innovative hemorrhage control concept made from 11 components, which included 3D printed parts and was manually assembled using small screws. The existing design would have been costly and challenging to produce at high volume while attempting to achieve ACT Medical\u2019s low COGS target. They had also carried out a usability study which had identified some key areas for improvement with the user interface.<\/p>\n

Over the 3-4 month period of our project working on the device, we developed an improved user interface design, designed replacement moldable parts and a bespoke welding\/assembly process, and produced injection molded parts ready to be assembled into functional devices usable for pre-verification and validation (pre-V&V) testing. The final devices were made from only 6 parts, and with a fraction of the assembly time required to produce devices with a much higher reliability than the initial prototypes.<\/p>\n

Deep penetrating trauma wounds\u2014particularly those that result in significant hemorrhage\u2014pose an ongoing challenge in emergency and battlefield medicine. These injuries are especially difficult to manage when they occur in anatomically complex areas such as junctional zones (e.g., the groin, armpit, or neck). In these non-compressible regions, standard hemorrhage control methods like tourniquets are often ineffective or completely unusable.<\/p>\n

Existing hemostatic products for treating these types of wounds often suffer from limitations. Many exhibit variable efficacy depending on the wound geometry, patient condition, or application technique. Others can be cumbersome to apply quickly in high-pressure situations. A significant concern shared across many of these products is the difficulty associated with removal during surgical intervention\u2014some materials can adhere strongly to tissue or fragment during extraction, increasing operative time and risk to the patient.<\/p>\n

Sanner has been supporting ACT Medical in their development of a novel solution designed to overcome these limitations. Their product utilizes direct internal pressure which aims to rapidly and effectively control hemorrhage at the point of injury, particularly at internal junctional bleeding sites, offering a potentially life-saving alternative where other options fall short.<\/p>\n

The development<\/strong><\/h2>\n

Throughout the project, there were a few key areas which were focused on:<\/p>\n

    \n
  • The User Interface<\/strong> – In emergency settings, usability is paramount. We refined the product\u2019s user interface with human factors at the forefront of our approach, through iterative ideation and in-house testing to ensure it can be deployed intuitively and consistently by first responders under stress and in challenging conditions.<\/li>\n<\/ul>\n

    • Designing for Manufacture and Assembly (DFMA) at Low Cost\/High Volume <\/strong>\u2013 As the device is single-use and has a high-volume potential market, it was key to optimize the product\u2019s design not just for clinical efficacy, but also for scalable and reliable production. Throughout the development, a focus was kept on suitability for injection molding and other scalable processes such as film welding, which was guided by the combined manufacturing experience of Sanner.<\/li>\n
    • Producing Prototypes Using Representative Methods <\/strong>\u2013 Before taking the step to high-volume manufacturing, we utilized prototype injection molding and worked with a supplier for film welding who was willing to work with us to produce initial low volumes but also capable of scaling up to high volume with the same design. We also developed a bespoke film-substrate welding process in-house, which allowed the devices to be assembled quickly and repeatedly and could also be scaled up to high volume. Overall, this approach to the device manufacture allowed the client to perform meaningful pre-V&V testing under conditions that closely mimic real-world use.<\/li>\n<\/ul>\n
