A vascular field simulator

Abstract

The application discloses a vascular field simulation device, including a controller, a driving mechanism, a blood simulation device, a simulated organ, and an oxygen ventilation device; the blood simulation device is used to simulate the blood environment at a preset temperature; the simulated organ is used to characterize the specific The organ has a predetermined number of simulation channels inside; the controller is used to control the switch of the oxygenation device, to control the amount of oxygen that the oxygenation device passes into the blood simulation device, and to control the movement of the driving mechanism; the driving mechanism is used for exercising Drive the blood combined with oxygen in the blood simulation device to input into the simulation channel, so as to measure the oxygen saturation of the blood through the measuring instrument set in the simulated organ, wherein, the driving force that changes periodically when the driving mechanism moves, the driving force The change is consistent with the human arterial blood curve. The application provides a more reliable and real simulation environment, which facilitates the testing and calibration of the measuring instrument.

Description

Technical field [0001] The present application relates to the field of biomedical technology, and more particularly to a blood vessel field simulation device. Background technique [0002] Real-time monitoring of arterial blood oxygen saturation is very important in clinical ambulance. The traditional blood oxygen saturation measurement method is to prepare a human body, and then use a blood gas analyzer to conduct electrochemical analysis, calculate the oxygen saturation. This method is more troublesome, causing secondary injury to patients and cannot be continuously monitored. Therefore, a wide range of research and attention can be obtained in real time, continuous and non-invasive blood oxygen saturation. [0003] Before the measuring instrument is put into application, it is necessary to test and calibrate, and the test is more troublesome by the human or animal, and the cost is high, and the simulation device is generally employed to provide the desired simulation environme...

AI Technical Summary

Problems solved by technology

The simulation environment provided by the current simulation device only simply considers the blood temperature, and the simulated vascular blood pressure is a constant value, while the blood pressure of the human blood vessels is continuously changing in a periodic fluctuation state, such as figure 1 As shown, it can be seen that the simulation environment provided by the existing simulation device deviates greatly from the real environment of human blood vessels, which has a negative impact on the testing and calibration of the measuring instrument
