Medical Technology
• The purpose of medical technology is to extend and improve life by alleviating pain, injury and handicaps.
• Billions of people rely on medical technology in their homes, at doctors offices, and in hospitals.
• More than 500,000 products are available today, such as wheelchairs, pacemakers, glasses, and bandages.
Types of Medical Technologies
• Currently Used Medical Technology• 3D Ultrasounds
• Newly Released Medical Technology• Microfluidic Chip to Diagnose Flu
• Dental Technology Advancements: Less invasive procedures and better experience for patients and dental professionals• Digital X-Rays• Intra-Oral Camera• Periodontal Laser
Currently Used Medical Technology:3D Ultrasounds
• 3D ultrasound is a medical ultrasound technique,
often used in obstetric ultrasonography (during
pregnancy), providing three dimensional images of
the fetus
• 3D ultrasounds allow one to see the width, height and depth of images in much the same way as 3D movies but no movement is shown
4D Ultrasounds
• 4D fetal ultrasounds are also offered. 4D ultrasounds are similar to 3D scans. 4D allows a 3-dimensional picture in real time, rather than delayed, 4D is similar to a movie compared to a still picture.
• The best time to have a 3D or 4D ultrasound is
when you are between 26 and 30 weeks pregnant.
Before 26 weeks your baby has very little fat under
His/her skin, so the bones of her/his face will show
through the skin
3D Ultrasounds: Pros
Pros
• Provides a detailed image of the baby, more lifelike
• 3D/4D is a keepsake ultrasound
• Can be used to educated women about abortion
3D Ultrasounds: Cons
Cons/Risks
• The clinics that offer these services are not currently regulated or approved by health regulatory bodies in Canada.
• Long-term effects of ultrasound are unknown and ultrasound that are just used for a picture and not for a medical purpose could put both mother and baby at an unnecessary risk
• According to Health Canada, there is "suggestive evidence" that ultrasounds can have a biological effect on the fetus.
3D/4D Ultrasounds
Risks of an ultrasound depends on the following factors:
• Duration of ultrasound exposure
• Intensity of ultrasound waves
• Frequency of ultrasound sessions
How to Reduce Ultrasound Risks
• Provide adequate training to ultrasound technologists
• Safety inspections of the clinic
• Regular inspections and maintenance of the ultrasound machine
• Limit ultrasound sessions to last no longer than 30 minutes
• Limit ultrasound sessions to no more than once a month
• Require proof of prenatal care prior to the 3D ultrasound session
Newly Released Medical Technology:Microfluid Chip to Diagnose Flu
• In 2009, the H1N1 flu spread across 200 countries and killed more than 18,000 people in the world
• During this time, diagnoses often took too long and false negatives were frequently seen
• For these reasons, researchers at US Universities performed a four year study to develop an alternative that would be as accurate as lab-scale diagnostics
Microfluid Chip to Diagnose Flu
• A microfluid chip was developed in early 2012
• A sample is taken and the chip extracts RNA from signature proteins from the influenza virus and converts it into DNA
• The DNA then replicates enough to be detected by the reader
• It has been found that the chip actually outperforms common flu diagnostics in accuracy
Microfluid Chip to Diagnose Flu
• The microchip is currently the size of a standard microscope slide
• It currently costs $10 a chip and results are produced within a few hours
• The research team is continuing to work on improving the chip so it costs $5 a chip and produce results in an hour
• A faster, more affordable test with fewer negatives could help minimize outbreaks and ultimately save lives
Microfluid Chips to Diagnose Flu: Pros and Cons
Pros
• Fast: Results can be seen within hours
• Disposable to reduce risk of cross contamination
• Accurate: outperforms most commonly used flu diagnostics
Cons
• Costly: $10 per chip
• Less environmentally friendly due to increased disposable slides
• Many people with the flu do not actually seek medical care
Dental Technology: Digital X-Rays
• X-Rays are essential for the diagnoses of dental caries and periodontal disease
• Digital x-rays have many more advantages over traditional x-rays, such as:• Less radiation is required for digital x-ray• More eco-friendly, traditional films use toxic chemicals to
develop the film, digital x-rays are scanned and can be reusable
• X-rays can be seen instantaneously on the computer and are easily shared for referrals or insurance purposes
Dental Technology: Intra-Oral Camera
• Intra-oral cameras are used to capture magnified images of specific areas of the teeth.
• This allows a patient to see what is going on in their mouth which can be a great motivational tool for improved self care.
• Images can be stored and used to compare the area of concern in the future.
Dental Technology: Periodontal Laser
• Periodontal laser can help reverse the symptoms of gum disease
• Laser is used to destroy bacteria and pathologic proteins in the pocket of the gums
• This procedure reduces the need of scalpel and stitches use
• Each patient is different but results from laser therapy can be seen after just 1 treatment
Dental Technology: Pros and Cons
Cons• Cost – Going digital is
very expensive
• Comfort – the sensor tends to be thicker making it less tolerable for the patient
• Many dental professionals would need additional training for use of the new products
Pros• Reduced radiation
• Faster to produce image
• No chemicals are used for film development
• Images can be manipulated to enhance the colour, aiding in diagnostics
Medical & Dental Technology Conclusion
• Risks need to be taken into consideration while using technologies, such as the 3D ultrasound. Its important to understand if the benefits outweigh the risks.
• The microfluid chip allows for easier and quicker results
• Dental technologies are useful tools for diagnoses, prevention and patient education
• Overall, health technologies are essential for the public to live a quality life, diagnose and prevent diseases and increase patient comfort
• The technological advancements made today creates an exciting outlook on what the future holds in medical sciences
