Description

Cuff for measuring blood pressure

Technical Field

The utility model relates to a medical equipment technical field, concretely relates to survey sleeve area for blood pressure is measured to human blood pressure.

Background

The sphygmomanometer cuff is used for measuring the blood pressure of a human body, the cuff is wound on a measured part of the human body and can acquire a pressure pulse wave signal in time to serve as blood pressure detection information, so that the blood pressure value of the measured human body can be accurately obtained, the fetal heart instrument is called a fetal heart rate instrument, fetal heart motion information can be acquired from the abdomen of a pregnant woman according to the Doppler principle, fetal heart sounds are played, and the fetal heart rate can be obtained through a counting algorithm.

Currently, the commonly used sphygmomanometer cuffs are mainly classified into the following two types:

the first sphygmomanometer cuff is provided with an independent built-in air bag, the air bag is arranged in a cloth sleeve with the periphery sewn, the tail end of the air bag is folded back through iron loops, and finally the air bag is tightly adhered through materials such as adhesive fabric and the like, so that the cuff has good comfort and high measurement accuracy, but is relatively complex to wear;

another sphygmomanometer cuff is convenient to wear, a bent flexible support is placed in a closed air bag, in order to ensure the tightness and stability of the air bag, a coating or a film is often applied to cloth, the whole material after the coating or the film is the main material integrating the air bag and the cloth, and because of the coating or the film, the main material has a certain thickness, and the difference of the circumferences of the inner circumference and the outer circumference after curling easily generates obvious hard wrinkles on the inner side of the cuff, so that the comfort is poor, and the hard wrinkles make the cuff not well close to the body, influence the pulse signal acquisition and further influence the accuracy; in addition, in the using process of the sphygmomanometer cuff, the flexible support can displace relative to the air bag, and the air bag can be worn by the flexible support after being used for many times, so that the air bag leaks air after being worn, and the service life of the cuff is shortened.

In view of the above, the present invention is to solve the above problems of the two cuff types and to develop a cuff for measuring blood pressure that can retain the common advantages of the two cuff types.
