- 1. Efficacy and safety: check...by using the right sensor solution Bram Stelt – Large Account Manager Booth: 551 Cell: +31(0) 6 2117 7287 [email protected] www.exergenglobal.com
- 2. Requests from the market: - Increased speed - Increased quality - Guaranteed safety Downside: - Same or less budget - More challenging conditions TRENDS
- 3. SOME EXAMPLES Welding Flash Cure
- 4. The right sensor - simply not enough - Innovative sensor technology - Smart mechanical engineering teams and - In depth know how of thermal processes APPROACH
- 6. SENSOR BY DESIGN………………THE PROCESS
- 7. Velashape II CASE STUDY – COSMETIC INDUSTRY
- 8. Potential Market for Fat Destruction Procedures In a survey of 1,045 women in NA 56% indicated interest in non-invasive fat destruction procedures Total Addressable Market in the US: 19.5M Patients World Market: $2 billion by 2017 ($700 million in the US - Globaldata) MARKET SIZE
- 9. Survey Takeaway: • “Pain-free with no downtime, it’s effective and totally believable.” • “Over 75% of patients come in to my office and immediately ask “How much is it going to hurt?" PAIN FREE TREATMENT - SAFETY
- 11. OBJECTIVE
- 12. Next generation, Velashape III: - Pain free treatments - More efficient treatment - No downtime. Request - Non contact temperature sensor integrated in applicator for skin temperature monitoring - Closed loop RF mechanism to ensure reaching the set-point skin temperature for optimal treatment efficacy, and NOT exceed the set-point temperature for patient safety and comfort. OBJECTIVE SYNERON
- 13. Our challenges: - Size – very limited space available - Direct IR lamp interference - Field of view – lens - Ambient temperature fluctuations - Gel applied on skin: thermal gradient. CHALLENGES
- 14. Solution: Sensor selection: - Small size - Thermocouple compatible - Unpowered - No drift - High accuracy - High repeatability - High interchangeability. OUR CHALLENGE: SIZE – VERY LIMITED SPACE AVAILABLE
- 15. Direct influence from IR lamps: immediate sensor response when IR lamps were switched on – measurement error of approx 3C. OUR CHALLENGE: DIRECT IR LAMP INTERFERENCE
- 16. Inner copper shroud blocking IR lamp radiation. Inner surface of shroud must be very low emissivity, otherwise the temperature of the shroud itself is measured. SOLUTION: DIRECT IR LAMP INTERFERENCE
- 17. OUR CHALLENGE: FIELD OF VIEW - LENS
- 18. SOLUTION: FIELD OF VIEW
- 19. SOLUTION: FIELD OF VIEW
- 20. No Power Required T/C Compatible Compensates for the Ambient Temperature AMBIENT TEMPERATURE COMPENSATION
- 21. ZnSe lens and window are not 100% transparent for IR radiation – some signal is absorbed: Sensor spectral response: 5.5 – 20 µm OUR CHALLENGE: BIG AMBIENT TEMPERATURE FLUCTUATIONS
- 22. The thermopile detector is responsive to the net power that it absorbs: P = σ * A * (Tt4 - Ta4) The Stefan-Boltzmann equation where: - P = net radiation power - A = surface area - Tt = target temperature - Ta = detector temperature. Since the detector absorbs power at σ * A * (Tt4) and re-radiates power at its own temperature, the σ * A * (- Ta4) term is needed. Tt is attenuated by the additional lens and window attenuate Ta is unchanged: ambient compensation error OUR CHALLENGE: BIG AMBIENT TEMPERATURE FLUCTUATIONS
- 23. 1) Sensor thermally isolated: slower heat up and more uniform heating 2) Additional thermocouple to measure sensor housing temperature to allow accurate ambient temperature compensation1. 1: solution that is provided to Syneron is under NDA and can not be disclosed here. The example given here is more general in nature but covers the concept SOLUTION: BIG AMBIENT TEMPERATURE FLUCTUATIONS
- 24. mVo mVTC SOLUTION: BIG AMBIENT TEMPERATURE FLUCTUATIONS
- 25. OUR CHALLENGE: GEL ON SKIN – THERMAL GRADIENT. SOLUTION: HEAT BALANCE
- 26. The results for Tt=24C and Tt=59C. - IRt/c = Initial temp. in degC, - t/c = additonal t/c temp in degC, - Corrected: with ambient temperature compensation - Scaled: with heat balance. RESULTS
- 27. VelaShape III Advantages Increased RF Power: - End point temperature is achieved much faster - Reduction in treatment time - Consistent, reproducible resultst Sophisticated Feedback Mechanisms: - New closed loop RF mechanism and built in temperature sensor - Better monitoring for elevated temperature in the tissue - Increased patient comfort and safety Movie
- 28. Two important items I would like you to walk away with: 1. Market is very demanding and keeps on challenging the industry 2. There is always a solution if the thermal process is thoroughly understood – sensor by design. TO TAKE HOME
- 29. THANK YOU – TIME FOR ? Bram Stelt – Large accountmanager Booth: 551 Cell: +31(0) 6 2117 7287 [email protected] www.exergenglobal.com www.sensoranics.com
Editor's Notes
- #2: Sensor = non contact infrared temperature sensors
- #3: - peil audience: wie in print, wie in medisch etc?
- #4: Wat willen jullie zien/horen
- #5: Uitdagingen worden te groot – off the shelve niet meer genoeg: steeds complexere machines Voorbeeld: HP: dubbele druk – concurrentie en druk van binnenuit. Hogere snelheid en nauwkeurigheid steeds belangrijker, en liefst zo klein mogelijk. Dit heeft grote gevolgen voor thermische processen. Getallen van de markt – groeimarkt. Non contact IR heel belangrijk voor snelheid en safety
- #8: Goed voorbeeld: cosmetisch industry is growing – vrouwen blijven vrouwen en het wordt bijna zomer
- #10: Syneron was marktleiden, maar dreigde die positie kwijt te raken. Moest een nieuwe flagship komen om weer nr1 in de markt te worden. Luisteren naar de klant.
- #11: Apoptosis of fat tissue: heating up fat tissue to set point temperature for certain time: fat tissue destroyed
- #12: Apoptosis of fat tissue: heating up fat tissue to set point temperature for certain time: fat tissue destroyed
- #13: Patients: pain free No lawsuits!!!! . Specialists: faster and no downtime – dus meer treatments in een dag – bigger revenue. Bredere doelgroep: van artsen naar beauty clinics – easy to use and safety guaranteed.
- #14: ONZE challenges
- #15: Praat over ‘we found a sensor’ niet Exergen specifiek benoemen
- #24: Unique solution for Syneron is under NDA: the solutions given here are more general in nature but grasp the concept
- #26: Non-contact IR sensing: only surface temperature is measured, which in this case is the gel and not the skin.
- #28: Flagship product met enorme voordelen – USP met als belangrijkste: safety.
