Precautions for the use of ECG monitor
1. Use 75% alcohol to clean the surface of the measurement site to remove the stratum corneum and sweat stains on the human skin and prevent poor contact of the electrode pads. Fasten the electrode tip of the ECG lead wire with the electrodes on the 5 electrode pads. After the ethanol evaporates,...Read more -
How to calibrate an electronic sphygmomanometer
Many hypertensive patients have some questions about the accuracy of electronic sphygmomanometers, and are not sure whether their measurements are accurate when measuring blood pressure. At this time, people can use the blood pressure standard to quickly calibrate the accuracy of the electronic s...Read more -

Distinguish between true and false blood pressure cuff
1. Materials 1. The cheapest inner capsule is made of EVA material, which is characterized by a hard, non-soft feel, and no elasticity when squeezed after inflation; it affects the accuracy and accuracy of blood pressure testing; 2. Secondly, some inner capsules are made of latex, which are softe...Read more -
Principles and significant advantages of medical disposable temperature probes
If you observe carefully, you will find that there are shadows of temperature sensors everywhere in life. As small as an infrared thermometer, then to the air conditioner at home, to the car when you go out. Whether it is industry or agriculture, the role of temperature sensors is becoming more a...Read more -
The method of measuring neonatal blood pressure
Core Tip: Newborns need to measure blood pressure after birth. The main measurement methods are the same as adults, but the width of the cuff used to measure blood pressure can be determined according to the age of different children, generally 2/3 of the length of the upper arm. When measuring n...Read more -
Patient monitor test parameters
Standard 6 parameters: ECG, respiration, non-invasive blood pressure, blood oxygen saturation, pulse, body temperature. Others: invasive blood pressure, end-respiratory carbon dioxide, respiratory mechanics, anesthetic gas, cardiac output (invasive and non-invasive), EEG bispectral index, etc. 1....Read more -
Classification of medical ultrasound probes
Ultrasonic probe (ultrasonic probe) is an indispensable key part of an ultrasonic diagnostic instrument. It can not only transform electric signals into ultrasound signals, but also transform ultrasound signals into electric signals, that is, it has the dual functions of ultrasound transmission a...Read more -
Ultrasonic probe (transducer)-inductance matching
Ultrasonic probe is a kind of transducer that converts the electric energy of super audio frequency into mechanical vibration. It is widely used in the fields of ultrasonic processing, diagnosis, cleaning and industrial non-destructive testing. It needs impedance matching with the generator to wo...Read more -

Why choose the right cuff size?
The position of the blood vessels in the human arm is fixed. By directly covering the cuff balloon on the blood vessel, the blood pressure signal can be captured correctly, so the cuff coverage rate has little effect on human blood pressure measurement. Full coverage of cuff airbag (100%): Correc...Read more -
The effect of loose or tight cuff on blood pressure
When the cuff is too loose, the blood pressure measured is usually higher than the accurate blood pressure value. When the cuff is too tight, the blood pressure measured is lower than the patient’s normal blood pressure. The cuff is essential when measuring blood pressure. In the process of tying...Read more
