Whether the smartphone iPhone-type ultrasound system can become a medical-grade "detector" like a stethoscope (as shown below) can be said to be a new multi-function iPhone, or a medical-grade iPhone-type ultrasound "detector".
It has entered the clinical universal application, it is not a technical problem (although it still needs to be improved and improved), it is only a matter of time.
iPhone portable ultrasound system.
At the Cleveland Medical Innovation Summit in October, the top 10 best innovative products and application technologies will be selected. Although this innovative product is not among the best, it still attracts the attention and comments of professionals in the industry.
This is an iPhone type ultrasonic detector. Recently, a doctor found himself suffering from cancer during clinical testing.
This is a Connecticut cardiovascular specialist who feels a little uncomfortable in his throat and tries to check himself with a smart iPhone-based ultrasound system developed by the startup.
When he inspected his neck with an iPhone-type ultrasonic tester according to the instructions, a high-density area of ​​3 cm in size was clearly displayed on the iPhone screen (below). He is not a oncologist, but his instincts make him feel that it is a lump. Further pathological biopsy confirmed that the mass was a squamous cell carcinoma!
Dr. Martin used the iPhone ultrasound system to determine that he might have cancer.
The development and production of this type of iPhone-type ultrasound system not only makes things cheap, but also makes the iPhone more useful. Therefore, the iPhone's price-to-price ratio exceeds that of conventional iPhone or medical ultrasound instruments. It is said that the equipment will be priced at $1999!
Where are the potential markets and applications?
Doctors who have tried this product have concluded that such an iPhone-type ultrasound system is suitable as a small medical device for home use and is an auxiliary monitoring or inspection device for future home health care.
The iPhone-based ultrasound system, Butterfly IQ, is the first of its kind to be admitted to the US medical services market.
Generally speaking, the ultrasound system equipped in the hospital is operated and applied by professional technicians (ie, B-room inspection, etc.). In the emergency room, you can assist the doctor to quickly determine the patient's heart, lungs, stomach and other basic conditions, without the need to use X-ray film.
However, hospitals or clinics are often not keen on ultrasound, but are more inclined to X-ray, or even CT or MRI. One of the reasons for this is that the application of large-scale equipment inspection can obtain considerable "profits or benefits" for the hospital.
At present, the startup has already invested 100 million US dollars to prepare to officially push the micro and portable ultrasound equipment to the medical service market. Earlier, there were similar products, such as Philips's Lumify, which sold for around $6,000. In addition to the price advantage, this iPhone-type ultrasonic detector also has advantages in imaging technology, and the image is more clear and stable.
In the clinical test application process, doctors' feedback evaluation is: compared with high-end ultrasonic testing equipment, image quality and diagnostic details are still lacking. If an ultrasonic testing device can be placed in the jacket pocket, the doctor can always Application, with a stethoscope to quickly determine the patient's condition changes, especially in the emergency room, doctors and nurses believe that this iPhone-type ultrasound system is still very practical.
The company hopes to further apply AI and other technologies to reduce its noise, enhance the image display function, and even quickly calculate the volume of the liquid, the amount of blood pumped by the heart, etc. through automatic image recognition software.
Improving the image processing technology and improving the diagnostic value of ultrasound examination is the broad application prospect and development direction of this type of portable mobile phone ultrasound system.
A companion device for the iPhone ultrasound system.

1. urine analysis strip is dry chemical reaction principle, the human body in the urine of white blood cells, proteins, ph, urine specific gravity, ketone body, bilirubin, occult blood, nitrite, uric bravery, glucose, creatinine, vitamin C, calcium within ten three indexes such as qualitative and semi-quantitative detection.
2. For the use of this product, we must pay attention to several points. For example, at the beginning, we should immerse all the reagent part on the urine analysis strip into the sample, and then take it out immediately.
3. Additionally, the edge of the urine analysis strip should be gently brushed along the mouth wall of the sample container to remove excess urine. Then place the reagent block on the urinalysis strip horizontally up and compare with the color map to record the results.
Rational use of urine analysis strip has played a very good role in our timely detection of disease and timely treatment
[Test Principle]
Urobilinogen:Urobilinogen with diazonium salt produce red violet dyes in strong acid medium.
Bilirubin:The direct bilirubin with dichlorobenzene diazonium produce azo dyes in acid medium.
Ketone:The acetoacetic acid and sodium nitroprusside cause reaction in alkaline medium,which produces red violet compound.
Blood:Hemoglobin acts as peroxidase. It can cause peroxidase release neo-ecotypes oxide (O).(O) oxidizes the indicator and make the color change subsequently.
Protein:It is based on a specific pH indicator attracted by cation on protein molecule,the indicator further ionized and make the color change.This phenomenon is called protein-error-of -indicator principle.
Nitrite:Nitrite and aromatic amine are diazotized to form a diazonium compound.The diazonium compound reacts with tetrahydrobenzo(h)quinolin 3-phenol produce the red azo dye.
Leukocyte:Pyrrole amino acid ester produce free phenol under the hydrolysis of esterase in neutrophile granulocyte,the free phenol couple with phenyl diazonium salt produce purple azo dyes.
Glucose:The glucose oxidized by glucose oxidase catalyzes the formation of glucuronic acid and peroxide hydrogen.Peroxide hydrogen releases neo-ecotypes oxide(O)under the function of peroxidase.(O)oxidizes tetramethyl benzidine, which make the color change.
Specific Gravity:Methyl vinyl ether and maleic acid copolymer is weak acid (-COOH) exchanger,the M+ cation (the major is Na+) in urine reacts with the exchanger and release hydrogen ion,hydrogen ion reacts with indicator produce color change.
pH:The method of pH indicator is applied.
Ascorbic Acid:Ascorbic acid deoxidizes the 2.6-dichlorphenolindophenol dye into colorless in alkaline medium.
Microalbumin:Sulfone phthalein dye has high sensitivity to microalbumin by the method of protein error.
Creatinine:Creatinine with 3,5-Dinitrobenoic acid produce violet compound in alkaline medium.
Calcium:Calcium ion reacts with methyl bromothymol blue produce color change in alkaline medium.
