The classification of sphygmomanometer and their respective characteristics:
1, mercury column (mercury column) type sphygmomanometer. There are two types of desktop, vertical, vertical sphygmomanometer can be adjusted at any height. Because the results are reliable and most commonly used, but the volume is slightly large, inconvenient to carry, and carry the process is easy to make the mercury leakage and affect the accuracy, so each measurement must be checked before the scale tube mercury convex surface is exactly in the zero position of the scale, pressure measurement is completed after the sphygmomanometer tilted to the right side of the 45-degree switch will be turned off, so as to avoid mercury leakage.
2, electronic sphygmomanometer. Electronic sphygmomanometer is the use of electronic pressure, beat sensor (instead of stethoscope) to identify the pressure and beat signals, and expressed in digital form, the upper part of the screen for the systolic blood pressure, the lower part of the diastolic blood pressure and pulse rate. Its advantages are easy to operate, intuitive readings, just press a button will automatically carry out the measurement, suitable for home use. However, electronic sphygmomanometers also have the disadvantage of a high error rate and need to be calibrated frequently against a standard mercury column sphygmomanometer.
3, barometer (spring) type sphygmomanometer. The use of pneumatic pump operation pressure, small size, easy to carry, and no mercury leakage shortcomings, but with the increase in the number of applications, will be due to the spring traits change and affect the accuracy of the results, so you need to calibrate regularly with the standard mercury column sphygmomanometer.
Blood pressure monitor what brand is good:
top1:Omron sphygmomanometer, produced in Japan, belongs to the most cost-effective one, more common in the family. The price ranges from more than 200 to more than 1,000 yuan, the measurement is fast and accurate, and the operation is convenient and easy to understand, more suitable for the elderly at home.
top2:Yuyue sphygmomanometer, Jiangsu Yuyue Medical Equipment Co., Ltd, its "Yuyue brand sphygmomanometer" and "Yuyue brand wheelchair carts" were rated by the General Administration of Quality Supervision, Inspection and Quarantine, respectively, is the "Chinese famous brand. Ltd, whose "Yuyue brand blood pressure monitor" and "Yuyue brand wheelchair trolley" were respectively honored as "China Famous Brand" by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, is the first enterprise in the medical equipment industry to obtain the "China Famous Brand", and is also the only medical equipment manufacturer in China with two "China Famous Brands".
top3:JiuAn sphygmomanometer, made in China, the measurement is also very accurate, the price is between 159-500 yuan, in the measurement of blood pressure based on the addition of six advantages:
(1) arrhythmia reminder function; (2) blood pressure zoning display; (3) individualized pressurization, the measurement of a more user-friendly; (4) cuff measurement instructions; (5) time memory display; (6) Large screen display, more beautiful appearance. Some models also add the function of voice announcement.
Buying tips for sphygmomanometers:
Tip 1: choose mercury sphygmomanometer or electronic sphygmomanometer?
①Professional doctors, of course, can choose mercury sphygmomanometer, because mercury column sphygmomanometer measurement accuracy and stability is higher, the user's technical requirements are higher. If the technology is not in place, improper operation, it is easy to make the measured blood pressure error.
②The general public, choose electronic blood pressure monitor. Electronic sphygmomanometers are simple to use and easy to measure.
Tip 2: electronic sphygmomanometer choose arm type or wrist type?
The purchase of blood pressure monitors should consider the situation of the user.
①Ordinary people, arm type or wrist type both can, wrist type measurement is convenient.
②Most middle-aged and elderly people (diabetes, hyperlipidemia, hypertension and other patients) use the arm type, for those patients with high blood viscosity, poor microcirculation, and mercury column sphygmomanometer results compared to the wrist, finger blood pressure measurements will be very large error. National hypertension guidelines consistently recommend an upper-arm electronic sphygmomanometer certified to international standards.
Tip 3: Should I choose automatic or semi-automatic pressurization for the measurement?
①Full-automatic machines press a button to automatically pressurize. Fully automatic is automatic control of the amount of incoming air.
②Semi-automatic is manually pressurized (pressurized by hand pinch rubber ball), manual is more troublesome, mainly into the volume of air is not very good control, less gas to test the pulse rate is not accurate.
Tip 4: Do you need to buy a memory function?
When you buy a sphygmomanometer, ask if it has a memory function. Sphygmomanometer memory function refers to the measured blood pressure records (high pressure, low pressure, pulse and other data) saved in the machine, can make long-term use of its measured on their own for a period of time the value of the blood pressure of the situation as clear as day, is a very good function. The memory function is generally divided into: single group memory and multi-group memory function; with date and time function and without date and time function.
How to use the blood pressure monitor correctly:
1, before measuring blood pressure, keep 5-10 minutes of quiet state, do not talk during the measurement, do not move the arm or body;
2, the correct measurement posture should be seated, the cuff and the heart should be at the same level, the upper arm naturally sagging, the elbow and the forearm naturally resting on a table, the palm of the hand upward (wrist type measurement requirements see Instructions);
3, continuous measurement of the same person, you should loosen the cuff, so that the arm rest for 3 minutes;
4, every day at a fixed time, usually choose to measure blood pressure before or after breakfast is more appropriate. Because this time the person has not much activity, measured blood pressure can be more real and reliable to reflect the physiological situation. To be the same, and then take an average.
5, the sphygmomanometer should be measured several times to take the average value, the use of electronic sphygmomanometer blood pressure measurement should be measured at least three times.
