Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a cuff for a sphygmomanometer using the upper-air measurement method. Background Art

[0002] The oscillometric method, also known as the oscillation method, is a common method for measuring blood pressure by using a cuff to pressurize the arterial blood vessels and judging the systolic pressure, mean pressure and diastolic pressure by using the pulse wave superimposed by the static pressure in the cuff and the arterial pressure; based on the oscillometric method, sphygmomanometers are divided into two categories: inflation-phase measurement and deflation-phase measurement, which use the upper-air measurement technology and the lower-air measurement technology respectively. Measuring blood pressure in the deflation phase has long been the mainstream technical solution of the oscillometric method. The main reason is that when measuring blood pressure in the inflation phase, the pulse wave is extremely vulnerable to being covered by the noise and vibration generated by the air pump operation, resulting in the pulse wave being unrecognizable. However, because the time required for the upper-air measurement technology is shorter than that required for the lower-air measurement technology, and the maximum value of the pressure applied by the upper-air measurement technology is also lower than that of the upper-air measurement technology, the sphygmomanometer using the upper-air measurement technology is more economical and applicable, can greatly save the time for measuring blood pressure, and has better clinical application prospects.

[0003] In order to overcome the interference of the vibration and noise of the air pump on the pulse wave signal, there are two traditional solutions: 1. Adding a high-order low-pass filter to filter out the air pump interference, such as an inflatable blood pressure measurement device disclosed in Patent No. CN202020507312.2; including a pressure cuff, a pressurizing air pump, a pressure sensor, and a filtering element connected between the conveying pipeline unit and the air pipe; this inflatable blood pressure measurement device eliminates the interference caused to the pulse wave by the filtering element, so that the pressure sensor can convert a better pulse signal quality; 2. Designing a complex air pump and adding a control unit for the air path, such as an air pump theme, an air pump and a sphygmomanometer disclosed in Patent No. CN202221957888.4; the air pump body includes an upper cover body, a control airbag, and an air flow channel on the upper cover body through which the gas drawn into the control airbag passes through a buffer air chamber and then is sent out through an inflation port, and a valve for opening or closing the air flow channel is also assembled on the upper cover body; this air pump ensures small air flow fluctuations and stable air flow inside the air pump without increasing the volume, and reduces the interference of the air pump on the pulse signal during blood pressure measurement; in order to reduce the interference of the air pump on the pulse wave, the above technical solutions have a very complex structure design of the air pump or sphygmomanometer, which is not conducive to the cost control of enterprises and has low practicability.
