Technical Field

[0001] The present invention relates to a respiratory motion simulation experimental device, in particular to an experimental device which simulates human respiratory frequency, tidal volume, and chest and abdominal cavity motions, and is mainly used in the fields of medical research, respiratory disease research, and medical equipment testing. Background Art

[0002] The human body's breathing process not only involves gas exchange in the lungs, but also causes movement of the chest and abdomen. Most existing breathing simulation devices can only simulate a single physiological parameter, such as tidal volume or respiratory rate, and cannot fully and accurately reproduce the complex breathing pattern of the human body. In particular, there are still technical limitations in simulating the movement of the chest and abdomen and their linkage with respiratory signals. Therefore, it is of great practical significance to develop a simulation device that can fully and accurately simulate the human respiratory rate, tidal volume and their effects on the movement of the chest and abdomen. Summary of the invention

[0003] The purpose of the present invention is to provide a respiratory movement simulation experimental device, which can simulate the breathing process of a real human body on an experimental platform by accurately controlling the human body's respiratory frequency, tidal volume, and the movement of the chest and abdominal cavities, thereby providing a controllable and accurate experimental platform for medical research, respiratory disease diagnosis, equipment testing, etc.

[0004] The technical solution of the present invention includes the following aspects:

[0005] Water bladder / hot water bag: used to simulate the movement of the human chest cavity, provide a bionic environment, and respond to simulated breathing movements.

[0006] In-vitro marker points: pasted on the surface of bionic skin, used to capture the movement changes of the chest surface in real time and reflect the dynamic situation of human breathing.

[0007] Bionic tissue model: It is made of gelatin particles and water in a ratio of 10:1, simulating the tissue structure in the human chest cavity, and a certain number of black glass balls are implanted inside it to simulate the target area in the body in the puncture experiment.

[0008] Stepper motor: used to drive the movement of the push rod. By adjusting the rotation frequency of the stepper motor, breathing movements of different frequencies can be simulated.

[0009] Push rod: connected to the stepper motor, the module slider is driven to move by the rotation of the screw. The slider is connected to the large-capacity syringe. The piston of the syringe is controlled by the reciprocating motion of the slider to simulate the breathing pattern of different tidal volumes.

[0010] Large-capacity syringe: connected to the push rod slider, controls the inflation volume of the hot water bag through piston movement to simulate the tidal volume of the human body.

[0011] Bionic skin: attached to the surface of the hot water bag, it simulates the surface movement of human skin and is used together with external markers to reflect the dynamic movement of the chest surface.

[0012] Binocular camera system: used to capture and record the movement of external markers in real time, reflect the dynamic changes of the chest surface, and provide real-time data support for the simulation process of respiratory movement.

[0013] The working principle of the present invention is as follows:

[0014] Respiratory rate simulation:

[0015] The rotation of the stepper motor drives the screw of the push rod to rotate, and the movement frequency of the slider of the module is adjusted to simulate the human breathing frequency (12-20 times / minute). The rotation frequency of the stepper motor matches the normal breathing frequency range of the human body.

[0016] Tidal volume simulation:

[0017] The movement of the push rod slider drives the piston of the large-capacity syringe to move. The piston of the syringe is connected to the hot water bag through the airway to control the inflation volume of the hot water bag.

[0018] Chest movement simulation:

[0019] The inflation or deflation of the hot water bag will cause its surface to deform, and the bionic skin and external markers attached to the surface of the hot water bag will move accordingly, simulating the movement of the human chest. The binocular camera system captures the movement trajectory of the markers in real time and accurately records the movement of the chest. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Furthermore, the water bag / hot water bottle 10 is used to simulate the movement of the human chest cavity, provide a bionic environment, and respond to the simulated breathing action.

[0026] Furthermore, the external marking points 6 are attached to the surface of the bionic skin 7 to capture the movement changes of the human chest surface in real time and reflect the dynamic situation of human breathing.

[0027] Furthermore, the bionic tissue model 8 is made of gelatin particles and water mixed in a ratio of 10:1 to simulate the tissue structure in the human chest cavity, and a certain number of black glass balls are implanted inside it to simulate the target area corresponding to the in vivo target 9 in the puncture experiment.

[0028] Furthermore, the push rod 3 is driven and controlled by a stepper motor, and the breathing movements of different frequencies are simulated by adjusting the rotation frequency of the stepper motor. The push rod 3 is connected to the stepper motor, and the slider is driven to move by the rotation of the screw, and the slider is connected to the large-capacity syringe 4.

[0032] The working principle of the present invention is as follows:

[0033] Respiratory rate simulation:

[0034] The rotation of the stepper motor drives the screw of the push rod to rotate, and the movement frequency of the slider of the module is adjusted to simulate the human breathing frequency (12-20 times / minute). The rotation frequency of the stepper motor matches the normal breathing frequency range of the human body.

[0035] Tidal volume simulation:

[0036] The movement of the push rod slider drives the piston of the large-capacity syringe to move. The piston of the syringe is connected to the hot water bag through the airway to control the inflation volume of the hot water bag. According to the tidal volume range of the human body (500-800 ml), the movement of the piston of the syringe accurately adjusts the inflation volume of the hot water bag to simulate the gas exchange process of the human body.

[0037] Chest movement simulation:

[0038] The inflation or deflation of the water bag / hot water bag 10 will cause its surface to deform, and the bionic skin 7 and the external markers 8 attached to the surface of the water bag / hot water bag 10 will move accordingly, simulating the movement of the human chest. The binocular camera system 1 captures the movement trajectory of the markers in real time and accurately records the movement process of the chest.

[0039] The device is set to simulate the normal human respiratory rate (15 times / minute) and tidal volume (600 ml). By adjusting the rotation frequency of the stepper motor and the movement amplitude of the push rod 3, a stable breathing rhythm is achieved. At the same time, the inflation volume of the hot water bag 10 is controlled by the large-capacity syringe 4, successfully simulating the gas exchange process of the human body. The movement of the marker point 6 is monitored in real time by the binocular camera 1 system to ensure that the simulation effect is consistent with the real human body.

[0040] By simulating breathing patterns under different physiological states, researchers can observe the effects of different tidal volumes and respiratory rates on chest and abdominal movements, providing a strong experimental basis for the diagnosis and treatment of respiratory diseases.
