Scope of Plastics Welding in Medical Device Manufacturing (Branson Ultrasonics)

The demand for medical devices is growing exponentially. The trend is towards using disposable devices. Therefore the demand for disposable devices is huge and growing all over the world. It is pre-requisite to make the device at minimum cost without compromising on the quality front. Use of plastics is increasing and to keep the manufacturing costs down for complex components, manufacturers are resorting to welding techniques.

Branson has always been on the forefront of developments in plastics joining with pioneering research. We have range of technologies to weld plastics that include ultrasonic, vibration, hot-plate, spin and laser. We would like to present how our technology helps OEMs with examples of component and the right process.

Pressure Sensitive Adhesives in Medical, In-Vitro, and Molecular Diagnostic Devices (Adhesives Research Incorporation)

Pressure Sensitive Adhesives (PSA) and functional coatings are increasing being used in the assembly of devices and components. Additionally, the adhesives are becoming sophisticated where these also play an active role in the actual functioning of the device. Adhesives Research Inc. is a leading developer and manufacturer of high-performance pressure-sensitive adhesive tapes, specialty coatings, films and laminates. These products find uses in a variety of medical device applications including membrane based IVD and molecular diagnostic testing, advanced wound care, lab-on-a-chip, microplate sealing, molecular technology, and transdermal drug delivery. Special requirements of some of these markets have forced us develop designer adhesives where not only the strength and quality of the bond is important but also where it adds value to the performance of the final device.

Ease of handling, allowing for a roll-to-roll continuous process in manufacturing, formation of well defined bond line, achieving an instant bond, wide choice of available chemistries and constructions are some of the advantages PSAs provide. This presentation will discuss the basic attributes of PSAs. Then the presentation will transition to the applications. Examples include electrically conductive adhesives as an active electrode in electrochemical biosensors. Hydrophilic coatings assist in the flow and filling of channels in microfluidic devices. Porous adhesives for high end woundcare applications, lateral flow, vertical flow and flow-through assays. Hydrogel systems to meet the needs of advanced woundcare and active transdermal drug delivery systems. Dissolvable films are being explored as a means of delivering reagents to in-vitro diagnostic devices. Special adhesives are targeted for sealing of microplates used in molecular diagnostics such as high throughput screening, RT-PCR, protein crystallization, drug discovery, cell culture and compound storage. These exhibit superior optical clarity, low autofluorescence, low birefringence, excellent solvent and temperature resistance.
