Risico's, veiligheid en aansprakelijkheid bij medisch-technische innovaties

Reiniging, sterilisatie en opslag

Arts en patiënt moeten er zeker van kunnen zijn dat endoscopen en andere medische instrumenten schoon en veilig zijn aan het begin van elke operatie. Prionen, virussen, bacteriën maar ook restanten van reinigingsmiddelen en desinfectantia kunnen nare ontstekingen en zelfs levensgevaarlijke infecties opleveren. De vaststelling van contaminatie...

Bioclimatic in medische omgeving. TNO Onderzoek met innovatievoucher SenterNovem

De viertraps-luchtbehandelingstechniek van Bioclimatic is speciaal ontworpen om de lucht te zuiveren van allerlei zwevende deeltjes en micro-organismen. Met een innovatievoucher van SenterNovem heeft het bedrijf een oriënterend onderzoek laten uitvoeren door TNO naar eventuele medische toepassingen. Hierbij werden onder andere ook...

Optical fiber sensors for medical applications: Practical engineering considerations

The advantages of optical fibers as medical sensors are recognized world wide nowadays. Insensitivity to electromagnetic disturbances and relative small dimensions are the most well known properties. The advantages of fiber optic sensors are especially valuable within environments with high temperatures, aggressive or explosive chemicals, strong...

Systems in foil: Opening new perspectives in medical technology

Organic electronic devices produced on foil open promising new perspectives for incorporation in disposable medical devices or sterile packaging materials because they are thin, lightweight and flexible. However, for economical viable applications reliable and cheap large scale production methods are required. Such production technologies (e.g....

Optical sensor platforms by modular assembly of organic electronic devices

Organic electronic devices are ideal for incorporation in sensor devices due to their reduced thickness, weight, and flexibility. Here, we show that organic light emitting diodes (OLED) and organic photodiodes (OPD) can be used in a wide range of optical sensors. Printing technologies allow for cheap production of devices. Using a modular build...

In plane optical sensor based on organic electronic devices

Sensors based on organic electronic devices are emerging in a wide range of application areas. Here we present a sensor platform using organic light emitting diodes (OLED) and organic photodiodes (OPD) as active components. By means of lamination and interconnection technology the functional foils with OLED and OPD arrays form an in-plane...

Avoiding pitfalls in the road from idea to certified product (and the harsh clinical environment thereafter) when innovating medical devices

Innovation in medical technology is a critical chain of events, ideally leading to an improved situation for patient and staff as well as a nice profit for the supplier of the innovation. Unfortunately many innovative ideas are not successful in practice. This is often due to lack of: • Medical relevance, • Validity of the underlying technical...

In Vitro demonstration of an SpO2-Camera

Feasibility of pulse oxigraphy is examined using an in- vitro phantom, perfused with human blood by a heart- lung machine. 29 different oxygen saturation levels, measured with our experimental camera and a clinical pulse oximeter, were matched against laboratory blood gas analysis. Discrete transfer functions between measurements & laboratory...

Contrast enhancement of coronary arteries in cardiac surgery: A new multispectral stereoscopic camera technique

Remote non-invasive stereoscopic imaging of blood vessels: First in-vivo results of a new multispectral contrast enhancement technology

We describe a contactless optical technique selectively enhancing superficial blood vessels below variously pigmented intact human skin by combining images in different spectral bands. Two CMOS-cameras, with apochromatic lenses and dual-band LED-arrays, simultaneously streamed Left (L) and Right (R) image data to a dual-processor PC. Both...

Optische straling in arbeidssituaties: praktische aspecten bij implementatie in Nederland van de EU-richtlijn betreffende de blootstelling aan bronnen van kunstmatige optische straling

Dit rapport beschrijft de praktische aspecten van de implementatie van de Europese richtlijn voor beroepsmatige blootstelling aan bronnen van kunstmatige optische straling (Richtlijn 2006/25/EG). Het rapport is opgesteld om een beeld te krijgen waar kunstmatige bronnen van optische straling in Nederland voorkomen en met welke beheersmaatregelen...

Contactless multiple wavelength photoplethysmographic imaging: A first step toward "spO2 camera" technology

We describe a route toward contactless imaging of arterial oxygen saturation (SpO2) distribution within tissue, based upon detection of a two-dimensional matrix of spatially resolved optical plethysmographic signals at different wavelengths. As a first step toward SpO 2-imaging we built a monochrome CMOS-camera with apochromatic lens and 3λ-LED...
