Medical device development
TPU has a long history within medical device development, and has a deep understanding of the complete process from conceptualizing to test and verification, documentation and manufacturing. This case focuses on injection moulded components manufactured in volume measured in billions.
Plunger insertion
For a pharmaceutical company, TPU have developed a semi-automatic system for plunger insertion. The system can insert a plunger in a container (either a syringe or cartridge). The equipment is used for small series during development, trials etc.
Vivostat
Vivostat is a machine that produces so-called fibrin glue from a small amount of the patient’s own blood. The glue is produced in just half an hour and is extremely effective for stopping bleedings very fast - even bleedings from large blood vessels. TPU has developed, tested and produced the initial 20 machines of the production. The development includes a complete design and documentation of mechatronics including transducers (IR temperatures gauges, pressure sensors, laser, strain gauges, etc.) and actuator systems together with specification of software and control systems.
Autoinjector test equipment
TPU A/S has developed a test system including software that enables Autoinjector optical injection measurements. Injection time and needle lenght are measured using a dedicated high speed vision system.
Combined with the customer's own tensile test bench, the test fixture can also be used to measure the force to remove the safety cap, the activation force, as well as the needle protection force.
Garia Utility
The Garia Utility is an electric vehicle suitable for various practical applications. It is designed in Denmark.
TPU has assisted Garia during various critical design aspects.
Vision system for tensile testing
High speed vision system developed using FPGA timing.
Vision is often a usefull tool during testing and TPU has experience in architecture, design and programming of complete systems both for R&D, medical test environments and for industrial production equipment.
Through the years TPU has completed a series of more than 700 product development projects. Many projects have been classified as confidential due to the competitive situation of the client. Several of the confidential projects, which TPU has been involved in, have covered the entire development process from concept creation to design, verification and approval for 0-batch production. Furthermore, an associated production engineering function has also been part of the development process in many of these projects.
Patents
During various development projects TPU has often contributed with inventions suitable for patenting. The patents have given each client the competitive advantage, which the protection of a patent provides. These patents are either used directly to protect the specific product or to ensure freedom of operation for the future. TPU has participated in filing more than 50 patents.
The rights to the patents always belong to the clients, as is the case for all other rights connected to the output of the development projects.
