Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood pressure cuff with replaceable inner liner. Background Technique

[0002] A sphygmomanometer is an instrument for measuring blood pressure, also called a blood pressure meter. According to the design principle of measuring blood pressure, it is mainly divided into a sphygmomanometer using auscultation method and a sphygmomanometer using oscillometric method. The electronic blood pressure meters commonly seen in daily life refer to the blood pressure meters designed by using oscillating waves. It uses electronic pressure and oscillating waves to judge blood pressure. At present, a sphygmomanometer consists of multiple components, including a blood pressure cuff.

[0003] The existing blood pressure cuffs still have the following problems in use: that is, the inflatable inner liner of the blood pressure cuff and the outer surface are often designed with an integrated sewing connection structure. The outer surface is usually made of wear-resistant materials and has good durability. However, due to the need for frequent expansion and contraction of the inner liner, its service life is shorter than that of the outer surface. After the inflatable inner liner is damaged, it is relatively inconvenient to replace. Content of the Utility Model
