Description
Technical Field
The invention belongs to medical teaching instruments, and particularly relates to a human body pulse condition simulation device which can simulate the elastic deformation of different pulse conditions according to different requirements to realize the tactile representation of the pulse conditions.
Background
One beating cycle of the heart originates in the sinoatrial node, the activation of which is conducted first to the right atrium and through the atrial bundle to the left atrium, forming the P-wave on the electrocardiogram. The P-wave represents the activation of the atrium, the right atrium activation in the front half and the left atrium activation in the back half. Activation is completed by the atrial to ventricular start depolarization. And then left and right ventricular muscle depolarizes, etc. The pulse within the body's blood vessel is thus a pressure fluctuation created by the combination of ventricular pressurization and atrial decompression.
Western medicine has various biological slices, pictures, image data and the like to provide visual auditory sensation, tactile sensation and visual sensation, and is favorable for learning, communication and diagnosis. The pulse feeling of traditional Chinese medicine is an important means, and if the pulse feeling can be effectively and intuitively felt, the pulse feeling can be better used for learning, communication and diagnosis.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The human body pulse condition simulator shown in figure 1 comprises a systolic pressure generating device 1, a bionic elastic tube 2, a bionic biological skin and flesh structure 3, a diastolic pressure generating device 4, a servo drive power amplifier 5 and a drive signal generator 6. The bionic elastic tube 2 is respectively connected with the systolic pressure generating device 1 and the diastolic pressure generating device 4, and a one-way valve is arranged in the bionic elastic tube 2 between the systolic pressure generating device 1 and the diastolic pressure generating device 4 to ensure the one-way fluidity of the internal liquid. A bionic body surface skin and meat structure 3 is sleeved outside the bionic elastic tube 2; the systolic pressure generating device 1 and the diastolic pressure generating device 4 are in signal connection with a servo drive power amplifier 5, and the servo drive power amplifier 5 is in signal connection with a drive signal generator 6.
The systolic pressure generating device 1 and the diastolic pressure generating device 4 are respectively used for simulating ventricles and atria of the heart, and the bionic elastic tube 2 simulates arterial blood vessels; more specifically, the systolic pressure generating device 1 is used to simulate the process of pressure rise inside an artery when the heart contracts. The diastolic pressure generating device 4 is used for simulating the backflow of blood during diastole, so that the pressure fluctuation in the bionic elastic tube 2 is similar to the pressure change condition generated in a blood vessel in one period of actual heart pulsation; the density of the liquid in the bionic elastic tube 2 can be adjusted to simulate the blood conditions of different human bodies.
As shown in fig. 2, since the electrical signal for driving the heart to operate determines the activation and the depolarization of the atrium and the ventricle, in this embodiment, the driving signal generator 6 provides the driving voltage for the systolic pressure generating device 1 and the diastolic pressure generating device 4, and the driving voltage generated by the driving signal generator 6 is amplified by the servo driving amplifier 5 to drive the systolic pressure generating device 1 and the diastolic pressure generating device 4, respectively. The driving signal generator 6 and the servo driving power amplifier 5 can generate similar driving voltage signals by taking any actual electrocardiogram as a reference, and respectively drive the systolic pressure generating device 1 and the diastolic pressure generating device 4 to generate corresponding pulsating pressure waves.
In the present embodiment, since the driving voltage has significant fluctuation in a short time and is a complex high-frequency composite signal, the systolic pressure generating device 1 and the diastolic pressure generating device 4 need to realize different types of loading and unloading in a short time, and therefore, in the present invention, the systolic pressure generating device 1 and the diastolic pressure generating device 4 both use a broadband servo pump as a power source, and the broadband servo pump provides power for the liquid in the bionic elastic tube 2.
The pulse condition sensed by the human body when actually feeling the pulse is not the pressure pulsation deformation of the blood vessel, but the pulsation deformation of the blood vessel is the pulsation deformation after the filtering and the correction of the skin and meat structure of the body surface. The biological body surface skin and flesh structure filtering structure comprises a bionic elastic tube 2 and a bionic biological body surface skin and flesh structure 3. The bionic organism skin and flesh structure 3 and the bionic elastic tube 2 are both made of high molecular organic materials. The bionic organism skin and flesh structure 3 is a sac-shaped structure, and the semi-fluid high polymer material is filled in the bionic organism skin and flesh structure 3.
When the invention is used for pulse condition training, the pulse condition pressure fluctuation which is consistent with the description characteristics of the twenty-six pulses in the traditional Chinese medicine can be generated by controlling the systolic pressure generating device 1 and the diastolic pressure generating device 4. When the device is used for simulating the actual pulse condition, the soft tissue filtering effect can be corrected by adjusting the filling thickness and pressure of the bionic body surface skin and flesh structure 3, so that the simulation of skin and flesh soft tissues of different crowds is realized, and a better pulse condition reappearing effect is achieved.
Fig. 2 is a control flow chart of the present invention, wherein a driving signal generator 6 generates two specific driving voltage signals, which are amplified by a servo driving power amplifier 5 and then respectively used for driving a systolic pressure generating device 1 and a diastolic pressure generating device 4 to generate specific pressure pulsation in a bionic elastic tube, and the pressure pulsation is transmitted through the bionic elastic tube 2 and a bionic body surface skin and flesh structure 3 to finally generate a tactile sensible pulse condition on the outer surface of the bionic body surface skin and flesh structure of the device.
The above embodiments are only used for illustrating the design idea and features of the present invention, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present invention and implement the present invention accordingly, and the protection scope of the present invention is not limited to the above embodiments. Therefore, all equivalent changes and modifications made in accordance with the principles and concepts disclosed herein are intended to be included within the scope of the present invention.
