Description

Technical Field

[0001] The utility model belongs to the field of phantom experiment platforms, in particular to a cardiopulmonary resuscitation (ROSC) phantom experiment platform. Background Art

[0002] Cardiopulmonary resuscitation (CPR) is a first aid technique used to treat sudden cardiac and respiratory arrest using external means. Its primary goal is to restore the patient's spontaneous breathing and circulation. Return of spontaneous circulation (ROSC) is the onset of sustained heartbeat and respiratory activity after cardiac arrest. Signs of ROSC include breathing, coughing, limb movement, a palpable pulse, and measurable blood pressure. A phantom is an artificial system or device designed and manufactured with inspiration from the structure, function, or physiological mechanism of an organism. It typically simulates specific characteristics of an organism to achieve similar functions or behaviors.

[0003] During cardiopulmonary resuscitation, the patient's pulse wave can be analyzed to identify the patient's recovery of spontaneous circulation. Since obtaining the patient's pulse wave signal data involves many restrictions such as ethical privacy, the patient's condition, and environmental conditions, an in vitro simulation method can be used to perform mechanical simulation on a phantom model to obtain the pulse wave signal data. When simulating chest compressions for cardiopulmonary resuscitation, the phantom model can be pressed manually or with an electromagnetic actuator. The frequency and force of manual compression are unstable, and the active iron core of the electromagnetic actuator will repeatedly impact the phantom model. Since the phantom model is mostly made of bionic materials, the repeated impact of the iron core can easily cause damage to the phantom model, shortening its service life. Utility Model Content

[0004] In view of this, the utility model aims to provide a cardiopulmonary resuscitation (ROSC) phantom experimental platform to avoid damage to the phantom model when simulating chest compressions in cardiopulmonary resuscitation.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] Example 1

[0036] Figure 1 This is a schematic diagram of the structure of a cardiopulmonary resuscitation (ROSC) phantom experimental platform according to the first embodiment of the present invention. Figure 1 As shown, it includes: a phantom model component and a simulation pressing component;

[0037] The phantom assembly includes a simulated heart, simulated blood vessels, and simulated blood. The simulated heart and simulated blood vessels are connected, and the simulated blood flows within the simulated heart and simulated blood vessels. The simulated heart simulates the pumping function of the human heart and, through a corresponding control system, delivers simulated blood to the simulated blood vessels according to corresponding parameters such as frequency, pressure, and flow rate. The simulated blood vessels are made of biomimetic materials, with dimensions such as length and diameter similar to those of the simulated blood vessels, and have similar softness and ductility to human blood vessels, allowing the simulated blood to flow within them. The simulated blood is a liquid made of artificial materials, with similar viscosity, density, and fluidity to human blood, used to simulate the flow of blood within human blood vessels.

[0038] The simulated pressing assembly includes: a pressing motor 12, an eccentric connecting rod 14, a reciprocating pressing rod 17, a pressing head 19 and a pressing controller. The output shaft of the pressing motor is an eccentric shaft 13, one end of the eccentric connecting rod is connected to the eccentric shaft, one end of the reciprocating pressing rod is connected to the other end of the eccentric connecting rod, and the pressing head is arranged at the other end of the reciprocating pressing rod. The pressing surface 20 of the pressing head is a smooth circular surface, the pressing surface contacts the simulated blood vessel, and the diameter of the pressing surface is larger than the diameter of the simulated blood vessel. The pressing motor is used to drive the pressing head to press the simulated blood vessel at a preset frequency, and the pressing controller is electrically connected to the control end of the pressing motor. The simulated pressing assembly is used to simulate chest compression during cardiopulmonary resuscitation. The pressing motor is arranged on the support plate 15. The top end of the eccentric connecting rod is rotatably connected to the eccentric shaft of the pressing motor. The bottom end of the eccentric connecting rod is rotatably connected to the top end of the reciprocating pressing rod via the connecting shaft 16. The reciprocating pressing rod is sheathed with a limiting cylinder 18. The limiting cylinder is used to keep the reciprocating pressing rod in a fixed posture when the reciprocating pressing rod moves, and to perform lifting and lowering movements along its own axis. The pressing head is arranged at the bottom end of the reciprocating pressing rod. The bottom of the pressing head is cylindrical, and the bottom surface of the cylinder is the pressing surface. The simulated blood vessel is arranged under the pressing surface and in contact with the pressing surface. The pressing controller is used to control the start and stop of the pressing motor and the speed of the pressing motor so that the pressing head driven by the pressing motor can press the simulated blood vessel at a frequency that complies with the relevant regulations on chest compression during cardiopulmonary resuscitation.

[0039] In this embodiment, the eccentric connecting rod is driven to move by the eccentric shaft of the pressing motor, and the reciprocating connecting rod is driven to move up and down, so that the pressing head can move up and down along the axial direction of the reciprocating connecting rod. By converting the eccentric motion into linear reciprocating motion, the converted linear motion and the motion trajectory of the eccentric shaft are on the same plane, and the direction of the linear motion is the same as the diameter direction of the circle, thereby achieving the effect of pressing the simulated blood vessel with the pressing surface.

[0040] The motion process of this embodiment is: four points A, B, C, and D are evenly arranged in a clockwise direction on the circular motion trajectory of the eccentric shaft, point A is the highest point of the circular motion trajectory, point C is the lowest point of the circular motion trajectory, and the line connecting points B and D is perpendicular to the line connecting points A and C and intersects with the center of the circular motion trajectory; when the eccentric shaft moves from point A to point B, the reciprocating connecting rod performs a gradually accelerated descending motion, when the eccentric shaft moves from point B to point C, the reciprocating connecting rod performs a gradually decelerated descending motion, when the eccentric shaft moves from point C to point D, the reciprocating connecting rod performs a gradually accelerated ascending motion, and when the eccentric shaft moves from point D to point A, the reciprocating connecting rod performs a gradually decelerated ascending motion.

[0041] It can be seen that under the drive of the eccentric shaft, the process of the reciprocating connecting rod descending changes from gradual acceleration to gradual deceleration, and the motion state before descending to the lowest point is gradual deceleration. Before the pressing head driven by the reciprocating connecting rod is pressed down to the lowest point, the downward pressing speed also gradually slows down. Combined with the fact that the diameter of the pressing surface is larger than the diameter of the simulated blood vessel, the pressing surface increases the contact area with the simulated blood vessel as much as possible, and the pressing force is evenly dispersed, which can effectively reduce the impact and destructiveness of the pressing head on the simulated blood vessel and extend the service life of the phantom model component.

[0042] An optional implementation of this embodiment is to obtain data as close to the real human body as possible, such as Figure 2 As shown, the simulated blood vessels are fabricated based on the human cardiovascular system and include: the brachiocephalic artery 11, the ascending aorta 10, the common carotid artery 1, the axillary artery 2, the thoracic aorta 3, the abdominal aorta 4, the brachial artery 9, the common iliac artery 7, the external iliac artery 5, the femoral artery 6, and the radial artery 8. The simulated blood vessels include the major arteries in the human body that connect to the heart, from which blood is pumped. To closely resemble human blood vessels and produce experimental data that approximates real human data, the simulated blood vessels are constructed using biomimetic materials. For example, the simulated blood vessels can be made of silicone. This silicone is a medical-grade silicone made from high-purity two-component room-temperature silicone, catalyzed by platinum or peroxide. This silicone is non-toxic, odorless, physiologically inert, heat-resistant, and has excellent biocompatibility. When creating the simulated blood vessel model, the length and inner diameter of adult blood vessels can be replicated based on the actual human cardiovascular system. A three-dimensional point cloud and volume model of the blood vessels can then be created. 3D printing can then be used to create a precise in vitro cardiovascular model to serve as the simulated blood vessel.

[0043] In this embodiment, the pressing surface contacts the abdominal aorta, and the diameter of the pressing surface is larger than the diameter of the abdominal aorta. During chest compressions for cardiopulmonary resuscitation, according to relevant operating guidelines, the compression pressure primarily acts on the abdominal aorta. Therefore, when simulating chest compressions, the compression force should also be applied to the abdominal aorta. To maximize the contact area between the compression head and the simulated blood vessel, the diameter of the pressing surface should also be larger than the diameter of the abdominal aorta being pressed to protect the simulated blood vessel, which is made of a relatively soft material.

[0044] Optional, such as Figure 3As shown, the simulated heart includes a DC liquid pump and a simulated heart controller, the simulated heart controller is electrically connected to the control end of the DC liquid pump, and the output end of the DC liquid pump is connected to the common carotid artery. In order to simulate the blood pumping function of the human heart as much as possible, the DC liquid pump is used as a driving component for simulating blood. Accordingly, the simulated heart controller includes a motor speed regulator, a motor control board and a power supply, the motor speed regulator is electrically connected to the DC liquid pump, and is used to control the speed of the drive motor in the DC liquid pump and the pumping frequency of the DC liquid pump, the motor control board is electrically connected to the motor speed regulator, and is used to send control instructions to the motor speed regulator to change the pumping frequency of the DC liquid pump controlled by the motor speed regulator, and the power supply is electrically connected to the motor control board, and is used to supply power to the DC liquid pump through the motor control board and the motor speed regulator.

[0045] For example, the motor control board can receive a heart rate setting instruction and convert it into a control instruction to control the pumping frequency of the DC pump according to the set heart rate. For example, if the heart rate setting instruction is 72 beats / minute, the motor control board will send a control instruction to the motor speed controller to set the pumping frequency of the DC pump to 72 beats / minute, consistent with the set heart rate, thereby more directly simulating the pumping function of the human heart. To more realistically simulate the circulation of human blood flow, the DC pump delivers simulated blood through the common carotid artery to the interior of the simulated blood vessel. The simulated blood flows from the common carotid artery into the ascending aorta of the simulated blood vessel and then to other arteries. The DC pump is controlled by a square wave with a 50% duty cycle. When the duty cycle is high, the DC pump delivers simulated blood to the simulated blood vessel, and when the duty cycle is low, the DC pump stops, thereby simulating the contraction and relaxation states of the human heart. The duty cycle of the square wave signal can be adjusted by the motor speed controller. A higher duty cycle increases the instantaneous operation time of the DC pump and increases the pumping intensity of the simulated heart, thereby simulating different heart pumping intensities.

[0046] To collect pulse wave data that is closer to reality, a pulse wave collector is also installed on the brachial artery. When actually collecting pulse waves, the pulse wave sensor needs to be placed on the human arm. The collected signal is the pulse signal of the brachial artery in the arm. Therefore, placing the pulse wave collector on the brachial artery can collect a pulse wave signal that is closer to reality.

[0047] Example 2

[0048] Figure 4 This is a schematic diagram of the structure of a cardiopulmonary resuscitation (ROSC) phantom experimental platform according to the second embodiment of the present invention. This embodiment is optimized based on the above embodiment. In order to make the phantom model more realistically simulate the blood circulation of the human body, such as Figure 4As shown, the phantom assembly also includes a fluid reservoir containing simulated blood. The reservoir's output is connected to the simulated heart, and its input is connected to the simulated blood vessels. The reservoir serves as a circulation loop for the simulated blood vessels, with its input connected to the femoral artery of the simulated blood vessels. The fluid reservoir, through the femoral artery, recovers simulated blood pumped out by the simulated blood vessels due to their inherent elasticity when the DC pump stops simulating the human heart's diastolic state. The recovered simulated blood is then transported to the DC pump, ensuring a sufficient supply of simulated blood to the simulated heart. The simulated blood circulation route is: reservoir - DC pump - simulated blood vessels - reservoir. The reservoir can store sufficient simulated blood to meet the needs of the simulated heart and blood vessels, preventing inaccurate experimental data due to simulated blood loss during the experiment. It also serves as a circulation loop with the simulated heart and blood vessels to more realistically simulate human blood circulation.

[0049] Example 3

[0050] Figure 5 This is a schematic diagram of the structure of the adjustment bracket described in Example 3 of the present utility model. This embodiment is optimized based on the above embodiment. In order to meet various experimental conditions, the simulated pressing component also includes an adjustment bracket. The pressing motor is arranged on the adjustment bracket. By changing the height of the pressing motor on the adjustment bracket, the height of the pressing head can be adjusted, thereby adapting to experimental conditions with different pressing requirements.

[0051] An optional implementation of this embodiment is as follows: Figure 5 As shown, the adjustment bracket includes a base 25, a pillar 21 and an adjustment seat, the pillar is set on the base, the adjustment seat is movably set on the pillar, and the pressing motor is set on the adjustment seat. The base is used to carry the simulated blood vessels and other equipment required for the experiment. The bottom end of the pillar is fixedly connected to the top surface of the base. The adjustment seat includes an adjustment plate 23 and a support plate 15. The adjustment plate is fixedly connected to the support plate. The adjustment plate and the pillar are detachably connected by bolts 24. The pressing motor 12 is set on the support plate. The eccentric connecting rod 14 is rotatably connected to the eccentric shaft 13 through the eccentric shaft sleeve 22 at the top. The limit cylinder 18 is set on the support plate. By changing the height of the adjustment plate on the pillar, the height of the pressing motor can be changed, and then the height of the pressing surface from the top surface of the base can be adjusted to be suitable for pressing simulated blood vessels of different diameters.

[0052] The present invention simulates the blood circulation of a real human body by simulating a heart, simulated blood vessels, and a fluid storage tank. The simulated blood vessels are manufactured based on the distribution of the real human cardiovascular system. The simulated pressing assembly presses the abdominal aorta of the simulated blood vessels, more realistically recreating the state of chest compression during cardiopulmonary resuscitation. A pulse wave collector is provided on the brachial artery of the simulated blood vessels to collect the required data. The simulated pressing assembly converts the eccentric motion of the eccentric shaft of the pressing motor into linear reciprocating motion driven by a reciprocating pressing rod. The pressing speed gradually decreases before the pressing head reaches its lowest point. The pressing head and the simulated blood vessels have a large contact area, which can effectively prevent the simulated blood vessels from being damaged by linear impact and extend the service life of the phantom model.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
