Abstract

The invention belongs to the technical field of medical instruments and provides a pulse wave blood pressure simulator which comprises a blood pressure simulating device, a pressure sensor, a pulse wave simulating device and a controller. The blood pressure simulating device is used for simulating human pressure signals and comprises a flexible rubber hose filled with gas and capable of elastically extending and contracting and a squeezing component used for squeezing the flexible rubber hose, the flexible rubber hose is arranged in the squeezing device, the pressure sensor is used for detecting pressure in the flexible rubber hose and connected with the flexible rubber hose, the pulse wave simulating device is used for simulating human pulse wave signals and comprises an inflation pump used for providing pulse airflow, the controller is used for controlling working state of the blood pressure simulating device and the pulse wave simulating device and collecting information fed back by the pressure sensor, and the blood pressure simulating device, the pulse wave simulating device and the pressure sensor are all electrically connected with the controller. The pulse wave blood pressure simulator can truly and accurately simulate human blood pressure and pulse signals and can be used for accurately detecting blood pressure. The invention further provides a simulating method matched with the pulse wave blood pressure simulator.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a pulse wave blood pressure simulator and a simulation method thereof. Background technique [0002] In the process of producing sphygmomanometers and when testing the quality of finished sphygmomanometers, it is usually necessary to use a blood pressure simulator to test the accuracy of the sphygmomanometer and check whether the quality of the sphygmomanometer is qualified. However, the existing blood pressure simulators can only be used to test sphygmomanometers using the oscillometric principle. The blood pressure simulator designed for the oscillometric principle can only be used to test a single cuff sphygmomanometer, and cannot be used to test the pulse wave principle. Measuring sphygmomanometer. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a pulse wave blood pressure simulator tha...
