Description

Technical Field [0001] The present invention relates to a portable blood pressure waveform reproducing apparatus and a portable blood pressure waveform reproducing apparatus,

The present invention relates to a method and apparatus for reproducing a blood pressure waveform in a portable device by rotating a pulse pressure waveform inflexible plate.

FIG. 1A shows graphs depicting the aortic root pressure, left ventricular pressure, left atrial pressure, and left ventricular volume for cardiac activity. Fig. 1B is a schematic view showing each part of the human heart. 1C is a table summarizing the time duration of each of left atrial contraction, left ventricular static contraction, release, static relaxation, rapid inflow, and cardiac arrest.

1D is a graph showing the pressure and volume graphs in the left ventricle (left graph) and the left ventricular end-diastolic volume (left graph) as the cardiac arrest, the closing of the endocardium, the left ventricular diastolic contraction, the opening and closing of the aortic valve, And a graph of the pressure and the volume in the chamber. FIG. 1E is a schematic view showing a human heart, an ascending aorta, a subclavian artery, a descending thoracic aorta, and a pulmonary artery. FIG. 1F shows a graph of a central blood pressure in the aorta.

As shown in FIGS. 1A, 1B, 1C, and 1D, the left atrioventricular valve closures, left ventricular diastolic contraction, aortic valve opens, release, release valve closes, left ventricular diastolic relaxation, The heart stopper is circulated by one cycle.

Therefore, it is possible to reproduce the ultrasensitive artificial blood pressure waveform that is the same as the blood pressure waveform of an actual person, by reproducing the same procedure as the actual heart operation method.

Conventional blood pressure waveform simulator has tried to make blood pressure waveform through open-loop control by using circular motion of piston, cylinder, and piston. However, there is a problem that the circulation of the fluid is performed in a different manner from the human body because there is no device for acting as a left atrium, and a pressure pattern expressing various cardiovascular diseases can not be generated by controlling the open circuit.

Conventionally, there are hydraulic apparatuses which attempt to reproduce the shape similar to the blood flow of an actual heart. Conventional hydraulic blood drive system has been developed as a cardiac pump using a rotary motor and a slider-crank structure. However, it is difficult to control the precision displacement because of noise and excessive vibration, coupled with force and speed. There is a problem that it can not express various cardiovascular diseases, and there is a problem that turbulence is generated by using a ball check valve.

In addition, the conventional arterial training wrist device has been developed for the training of a nurse who uses a DC geared motor and a slider crank structure to insert a syringe by looking for an arterial blood vessel. However, there is a problem of noise and residual vibration, And thus it is difficult to control the precision displacement and thus it is difficult to express diverse cardiovascular diseases.

Conventional hydraulic blood flow drive system is developed for precise discharge and control of fluid by applying step motor, timing belt and lead screw. It enables precision displacement and force control and minimizes noise, vibration and heat transfer effect. However, It has a disadvantage that it is not suitable for simulating the blood flow of the heart.

Non-Invasive Blood Pressure (BP), which can store and reproduce pressure waveforms generated in the body by pneumatic pressure, can be used to evaluate the uncertainty of the pressure indicator (blood pressure sensor) Monitor Analyzer was developed by FLUKE.

In addition, the conventional pneumatic blood pressure drive system is used to make a comparison value that can calibrate a pressure gauge by simulating the pressure vibration generated in a person's arm by generating a pressure vibration of the air by reciprocating the piston.

However, such a pneumatic blood pressure drive system has been developed to simulate pressure oscillations occurring in arterial blood vessels. Since the air is compressible, there is a problem that it is not suitable to be applied to a blood pressure waveform reproducing apparatus for promoting the cuff because it is unsuitable for expressing the feeling of reflected waves and blood flow generated by the incompressible blood.

Conventional devices have attempted to create a pulsatile flow or blood pressure waveform by implementing the function of the left ventricle by utilizing a piston, a cylinder, and a motor that linearly moves the piston. However, the pulse wave or blood pressure waveform of a person is important for the function of the left ventricle as well as the function of the left atrium. The left atrium is generated by alternating positive pressure and negative pressure, so that arterial blood is sent to the left ventricle and arterial blood is supplied from the pulmonary vein again, so that closed circulation is performed in the human body. In the conventional patent documents, the functions of the left atrium are excluded, and it is difficult to make various blood flow similar to the human body.

In addition, the pressure in the left ventricle which directly makes the flow of the pulse is an important factor. In the conventional patent document, by adopting the open-loop control method without using the feedback of the pressure value, various cardiovascular diseases The pressure pattern of the pulse wave or the blood pressure waveform which can express the pressure wave pattern of the blood pressure.

Also, in order to reproduce the blood pressure waveform, the left ventricle and the left atrium may be simulated to generate the pulsating flow in the fluid occlusion circulation system. However, this system is not compatible with the apparatus, It is difficult to implement, difficult to supply, and difficult to maintain.

Therefore, it is required to develop a blood pressure waveform reproducing device which can be easily implemented with a pulse pressure waveform inflexible plate, can be carried in a small size, is economical, has a fast response speed, and can accurately implement a blood pressure waveform.
