How an oximeter works!
The working principle of the nail oximeter: by sequentially driving a red LED (660nm) and an infrared LED (910nm), the blue line indicates the induction curve of the receiving tube to the reduced hemoglobin when the hemoglobin does not carry oxygen molecules. It can be seen that the absorption o...Read more -

Differences between the three most common ultrasound probes
The three most common types of probes (also called ultrasonic transducers) are linear, convex, and phased array. The linear near-field resolution is good and can be used for blood vessel inspection. The convex surface is conducive to in-depth examination, which can be used for abdominal examinati...Read more -
What does a blood oxygen sensor do?
People breathe air every day, because the air contains oxygen, which is the basis for maintaining people’s lives. The reduced hemoglobin contained in people’s bodies combines with the oxygen ingested in the lungs to form oxygen and hemoglobin. Oxygen is dissolved in plasma to maintain...Read more -
The role of EEG
We know that when the precordial area is unwell, an electrocardiogram should be checked; when a part of the heart is unwell, a gastroscopy should be performed; When your head is uncomfortable, sometimes your doctor will do an EEG. So, why should an EEG be performed? What diseases can an EEG detec...Read more -

What is the principle of the probe
Test probes are small single-stranded DNA or RNA fragments (approximately 20 to 500 bp) used to detect complementary nucleic acid sequences. Double-stranded DNA is denatured by heating to become single-stranded, and then labeled with radioisotopes (usually phosphorus-32), fluorescent dyes, or enz...Read more -
