Description

Technical Field

[0001] The present application relates to the fields of medical teaching and popular science education, and specifically, to a double-sided alveolar simulation device. Background Art

[0002] At present, pictures, videos or simple models are often used to demonstrate the structure and function of alveoli in medical teaching and patient education. However, these methods cannot intuitively and dynamically display the morphological changes and pathological processes of alveoli, making it difficult for students and patients to understand them in depth. Therefore, a teaching model that can truly simulate the working state and pathological changes of alveoli is needed. Utility Model Content

[0003] The present application provides a double-sided alveolar simulation device, which can be used for teaching to realistically simulate the working state and pathological changes of alveoli.

[0004] To achieve the above objectives, this application provides the following technical solutions:

[0005] The present application provides a double-sided alveolar simulation device, comprising a shell, an alveolar simulation component and a dynamic simulation unit.

[0006] A bracket is provided inside the shell. Along the thickness direction of the shell, the bracket divides the inner cavity of the shell into a first chamber and a second chamber. Along the thickness direction of the shell, a first observation window and a second observation window are provided on opposite sides of the shell, respectively. The first observation window is used to observe the condition in the first chamber, and the second observation window is used to observe the condition in the second chamber. The alveolar simulation component is used to simulate alveoli. There are two alveolar simulation components. The two alveolar simulation components are respectively provided in the first chamber and the second chamber. The alveolar simulation group located in the first chamber is the first component, and the alveolar simulation group located in the second chamber is the second component. There are two dynamic simulation units, including a first dynamic simulation unit and a second dynamic simulation unit. The first dynamic module is connected to the first component and is configured to cooperate with the first component to display the first condition of the alveolar simulation component. The second dynamic simulation unit is connected to the second component and is configured to cooperate with the second component to display the second condition of the alveolar simulation component.

[0007] In the above scheme, the double-sided alveolar simulation device can be used for teaching of realistic simulation of alveolar working state and pathological changes. For example, the alveolar simulation group located in the first chamber displays the first condition of normal alveolar working state under the cooperation of the dynamic simulation unit, such as expansion or contraction of normal frequency or size, and the alveolar simulation group located in the second chamber displays the second condition of abnormal alveolar working state under the cooperation of the dynamic simulation unit, such as atelectasis pathological state, that is, small expansion degree, etc. Learners can visually observe two different conditions from the front and back sides of the shell through the first observation window or the second observation window, which is conducive to comparison and understanding.

[0008] According to some embodiments of the present application, the dynamic simulation unit includes an electric pump and a solenoid valve. The alveolar simulation component includes a main line and a balloon, the electric pump is connected to the main line, the main line is connected to the balloon, the electric pump is used to supply gas to the balloon through the main line, and the solenoid valve is connected to the main line and is used to release the gas in the balloon.

[0009] In the above scheme, the dynamic simulation unit supplies air to the balloon through the electric valve to simulate the expansion of the alveoli, and releases the gas in the balloon through the electromagnetic valve to simulate the contraction of the alveoli. On the one hand, the breathing frequency of the alveoli can be simulated by the switching frequency of the electric valve and the electromagnetic valve; on the other hand, by controlling the air supply of the electric valve, the expansion size of the balloon can be controlled, thereby simulating the expansion degree of the alveoli, thereby simulating the changes in different alveolar shapes; on the other hand, by controlling the different working states of the first dynamic simulation unit and the second dynamic simulation unit through different programs, learners can intuitively understand the morphological changes of different alveolar states from different windows, which is conducive to learning and understanding.

[0010] According to some embodiments of the present application, the alveolar simulation component includes three balloons of different sizes, and each balloon is connected to a main line through a branch line.

[0011] In the above scheme, by setting three balloons of different sizes, alveoli of different sizes in the lungs can be effectively simulated, which is beneficial to learners' learning and understanding.

[0012] According to some embodiments of the present application, a support plate is further provided in the shell, the lower surface of the support plate is connected to the bracket, the support plate and the top wall of the shell together form a third chamber, the support plate is formed with a perforation for the main line to pass through, and the solenoid valve and the electric pump are arranged in the third chamber.

[0013] In the above scheme, by setting the support plate, support can be provided for the main line, for example, the periphery of the main line is bonded to the perforated hole wall, and support can be provided for the dynamic simulation unit. At the same time, the observation window can be set under the support plate, which can hide the electric pump and the solenoid valve, so that the learner can only observe the alveolar simulation component, reducing the interference of other substances on learning. In some embodiments, a power supply can be set in the third chamber, and the power supply can power the dynamic simulation unit.

[0014] According to some embodiments of the present application, the balloon is bonded to the stent, and the main line and the branch line are respectively fixed to the stent by iron wires.

[0015] According to some embodiments of the present application, the dynamic simulation unit also includes a light source, which includes a blue LED lamp and a red LED lamp, and the light source is arranged in the balloon.

[0016] In the above scheme, by setting the light source, pulmonary blood circulation can be simulated. In some embodiments, by controlling the brightness, color and flashing frequency of the light source, pulmonary blood circulation is simulated. Exemplarily, during the inhalation process: the red LED light gradually becomes brighter, simulating the increase of oxygen content in the blood. During the exhalation process: the red LED light gradually becomes darker, and the blue LED light gradually becomes brighter, simulating the increase of carbon dioxide content in the blood.

[0017] According to some embodiments of the present application, the light source is connected to a wire, and one end of the wire passes through a branch pipeline.

[0018] In the above scheme, the wire supplies power to the light source and transmits signals. The wire can be led out through the air supply opening of the balloon and passed through the branch pipe to connect with the controller or other components to realize power supply and signal transmission to the light source. In some embodiments, the junction between the wire and the branch pipe is sealed.

[0019] According to some embodiments of the present application, the double-sided alveolar simulation device includes a controller, which is electrically connected to the dynamic simulation unit and is used to control the operation of components in the dynamic simulation unit.

[0020] In the above scheme, by setting a controller, the working state of the electric valve, the solenoid valve and the light source can be automatically controlled according to the program set by the controller. For example, the controller controls the operation of the electric pump and the solenoid valve according to the preset breathing mode and pressure threshold to simulate the inhalation and exhalation process. The controller can control the brightness, color and flashing frequency of the blue LED light and the red LED light based on the preset breathing mode and pressure threshold to simulate the blood circulation in the lungs.

[0021] According to some embodiments of the present application, the double-sided alveolar simulation device also includes a data acquisition module and a wireless transmission module. The data acquisition module is connected to the controller. The double-sided alveolar simulation device also includes a pressure sensor arranged in the balloon. The pressure sensor is connected to the controller and is used to detect the internal pressure information of the balloon. The wireless transmission module is connected to the controller and is used to transmit the information of the controller to the cloud or a local server.

[0022] In the above scheme, the pressure sensor monitors the pressure inside the balloon in real time and transmits the data to the controller. The controller can adjust the operation of the electric pump and the solenoid valve according to the pressure data and the preset threshold value to ensure that the balloon expands and contracts within a safe range. Through the wireless transmission module, the working data of the controller, such as breathing parameters and alveolar morphology change data, can be uploaded to the cloud or local server to facilitate learners to learn and understand from the data level. In other embodiments, the controller can also be controlled by the wireless transmission module through the host computer software or mobile application to set the breathing mode, monitor data and control the working status of the device.
