Challenges faced by designers of medical devices are among the most stringent in the world....
The high-density Fischer MiniMax Series combines signal and power in accordance with USB 3.0, HDMI and Ethernet protocols for high-speed data transfer.
As healthcare becomes more democratic and diversified, patients and healthcare professionals are demanding miniature, portable and wearable medical devices for use in varied settings. Versatility is key.
Fischer Connectors’ innovative interconnect solutions offer medical device designers more flexibility, enabling them to pack more functionality into mobile and patient-worn devices, without compromising regulatory compliance, safety and usability.
The ultra-miniature Fischer
MiniMax Series is an example of a high-density, low-weight solution to wearable and mobile equipment challenges. It comes in several configurations, with two sizes that provide between 4 and 24 connections, including power and signal in a choice of push-pull, quick-release and screw-locking systems. Rugged and with IP68 sealing for durability, MiniMax also features special contact blocks that meet the need for high-speed data transfer up to USB 3.0 or 10GB Ethernet.
An eagerly awaited product line extension to the Fischer MiniMax Series now provides rugged Ethernet. Following the success of the recent dedicated USB 3.0 contact block in the 08 size connector, the new configuration of eight American wire gauge (AWG) 24 contacts in the 08 size enables even faster data transmission via USB 3.0/Ethernet/HDMI protocols. Thanks to its redesign and production process improvements that enhance ruggedisation for extreme environments, the new standard IP68 sealing level enables all MiniMax connectors and cable assembly solutions to go even deeper, for example, 20m for 24 hours.
A second product extension improves data storage. The popular Fischer Rugged Flash Drive is an extremely tough memory stick that’s specially designed for the safe storage and transportating of sensitive data in harsh environments. It has been further adapted to the new MiniMax USB 3.0 connector interface, with nine poles being in optimised positions.
Cost-effective glass components
IMT produces customised high-precision, low-cost glass components.
Glass remains the material of choice for many biophotonic and microfluidic applications. It is inert to most chemicals, has unsurpassed well-defined optical properties, and has good temperature and pressure stability. However, glass components also have a reputation for being prohibitively expensive to manufacture, which means that using them as a consumable or semi-consumable in high-quantity applications is not cost-effective. In several cases, it appears to be the cost of the consumable glass components that prevents a new analytic method or technology from entering the mainstream.
Realising the market potential of high-precision but low-cost glass components, IMT of Switzerland is applying the foundry concept to the production of glass components for life sciences, such as microchannels, through-holes, electrodes and waveguides.
By bundling the development and production of glass components for many companies at one site and applying manufacturing technologies from the semiconductor industry, and thereby reaching attractive economies of scale, IMT can offer customised glass components at competitive prices.
IMT has more than 50 years’ experience as a supplier of custom-made glass components for a wide range of optical and sensor applications including delineated optics, reticles, gratings, mirrors and filters. The company’s core expertise is the coating and structuring of thin films using microlithography.
Its production environment, which includes 1,300m² of cleanrooms and a fully automated process line for 200mm glass wafers, is well suited to the mass production of lab-on-a-chip glass components, flow cells containing microchannels, and metallic and dielectric microstructures, in combination with waveguides and gratings.

The Leister Basic S is essential for effectively welding plastic components.
The new Basic S from Leister is the perfect integrable plastic laser-welding system for the medical industry. Incorporating a unique, state-of-the-art cooling system that was developed in-house, the Basic S is set to redefine the market. The permanent cooling of the laser ensures the precise and repeatable welding of plastic components.
To ensure products can be welded in accordance with stringent medical industry requirements, the Basic S is coupled with powerful software that can record and output all welding-process data and parameters in a single file. Newly developed management profiles divide users into operator, expert and service categories. This critical feature secures parameters from alteration and accidental loss. All parameter changes are recorded and saved in a log. This feature makes it possible to track who accessed information, and where and when data for process modifications were initiated.
A newly developed web-based human-machine interface (HMI) makes integrating the Basic S quick and intuitive. Digital, as well as analogue signals, are clearly displayed graphically and in real time. This new functionality makes it possible to detect which signals are on and off in the Basic S system at all times. Process parameters can be set using the web HMI or directly with the LCD display on the front of the system.
The Basic S can be operated with the innovative, modular Leister laser optics. In contrast to the BT line, premium AT optics offer fibre connection monitoring, laser power measurement and pyrometer functionality.
In April, the new Leister Basic S was presented for the first time at MedTec Europe 2018 in Germany.
