Environment-friendly composite material for sphygmomanometers

Abstract

The invention relates to an environment-friendly composite material for sphygmomanometers. The environment-friendly composite material is prepared by the following method: (1) high-strength, low-shrinkage polyester yarns as material are warped, woven, divided and rolled, so that a base fabric as framework material is produced; (2) the framework material is soaked in PU paste, coated, dried and preshaped, and a PVC (polrvinyl chloride) film is then attached on one surface of the framework material by a way of hot melting; (3) a layer of PU paste is applied on the surface of a non-woven fabric, dried and then attached on the other surface of the framework material by way of hot melting, and finally, after embossing, cooling for shaping and trimming, the environment-friendly composite material for sphygmomanometers is produced. Because both surfaces of the framework material of the environment-friendly composite material for sphygmomanometers is provided with the PU (Poly Urethane) paste layers, the peeling strength of the product is greatly enhanced, and the product can be used for not less than 20000 times. As the living standard of people is increased, people pay more attention to health, and such products have a broad market prospect.

Description

technical field [0001] The invention relates to a composite material, in particular to an environment-friendly composite material for a sphygmomanometer. Background technique [0002] The clinical indirect blood pressure measurement (cuff measurement) is a measurement method that uses a sphygmomanometer cuff to compress blood vessels. The pressure in the cuff gradually decreases to produce systolic and diastolic pressures. The pressure measured in the artery is reflected by the difference of the external atmospheric pressure. According to the principle of mechanical conduction, although the density of muscle, fat and other tissues in each body is different, it can reflect the pressure in the artery more accurately due to the inhomogeneity of mechanical conduction. In the same way, adding a thin cuff cover between the cuff of the blood pressure monitor and the skin of the body will have exactly the same effect as that of muscle, fat and other tissues.

Problems solved by technology

Therefore, the cuff is an important part of the sphygmomanometer, and it is also the part that is in direct contact with the patient. Usually, the cuff of the sphygmomanometer can be made of flexible composite materials, but currently such materials often contain heavy metals and phthalic acid. Salt pollution, a serious threat to the health of patients

In addition, it is also easy to separate the plush layer from the reinforcing material layer, which affects the service life of the cuff
