Mobile phones can be said to be the products that are being updated at the fastest speed at present. Basically, there will be new mobile phones on the market every day. Although Chinese people lack innovative thinking, there are various kinds of knock-off mobile phones, which make people look at them with new eyes. The product introduced today is about the same size as a Blackberry mobile phone, and even the shape is like a mobile phone. After seeing all kinds of mobile phones, do not think that this is a mobile phone because of the thinking inertia. In fact, it is a handheld ultrasound scanner. Usually, patients need to go to the hospital or doctor's office for a more detailed diagnosis. But now with this small handheld ultrasound scanner, doctors can take it to visit patients for diagnosis. Of course, this handheld ultrasound scanner is mainly for pregnant women to detect the situation inside the abdomen of pregnant women, and there are other uses that are not yet clear.
