In a first aspect, embodiments of the present application provide a cardiopulmonary resuscitation simulator.

Referring to fig. 1, the cardiopulmonary resuscitation dummy includes a dummy body 1, an airflow sensing module 2, a compression sensing module 3, and a data transmission module 4.

The dummy body 1 is a human body model made of plastic, silica gel, rubber and the like according to requirements.

The oral cavity position of anthropomorphic dummy body 1 is provided with an airflow channel 11, and this airflow channel 11 one end intercommunication anthropomorphic dummy oral cavity position, the other end can extend to another arbitrary position of intercommunication anthropomorphic dummy body 1 external atmosphere environment in anthropomorphic dummy body 1, only need the airflow in the airflow channel 11 can be unblocked. When the learner blows air to the port of the air flow passage 11 located at the oral position, an air flow is generated in the air flow passage 11 and is discharged from the other port of the air flow passage 11.

The airflow sensing module 2 is disposed in the airflow channel 11 and is configured to sense airflow data in the airflow channel 11. The airflow sensing module 2 can select any sensing element or sensing device with airflow data sensing function, and in this embodiment, it is specifically selected to be a hall airflow sensor. The hall airflow sensor is arranged at one end of the airflow channel 11 close to the oral cavity, and can sense airflow data in the airflow channel 11, wherein the airflow data specifically comprises the speed and the temperature of airflow.

A containing cavity is arranged in the chest position of the dummy body 1, and the pressing sensing module 3 is arranged in the containing cavity. The pressing sensing module 3 specifically includes an elastic member 31 and an elastic sensing member 32, wherein two ends of the elastic member 31 respectively abut against the front end (i.e. the end facing the direction of the human simulator body 1) and the rear end (i.e. the end facing the direction of the human simulator body 1) of the chest position, and the elastic sensing member 32 is disposed between the end portion of the elastic member 31 close to the rear end and the rear end. When the dummy is used for practicing cardiopulmonary resuscitation, the dummy body 1 is laid on a plane such as the ground, a bed surface or a table surface, a learner presses the chest position of the dummy body 1 downwards, the elastic piece 31 is compressed, the elastic force sensing piece 32 can sense the elastic force data of the elastic piece 31, and under the condition that the stiffness coefficient of the elastic piece 31 is determined, the elastic force data can reflect the compression amount of the elastic piece 31, namely the depth of the chest of the dummy body 1 pressed down by the learner.

It should be understood that the chest position of the dummy body 1 should be made of flexible material to ensure that the chest position of the dummy body 1 can be pressed down, and other positions of the dummy body 1 may be rigid, flexible or any other property.

The elastic member 31 only functions to provide elastic force, and the stiffness coefficient thereof is set to be similar to that of the chest cavity of the human body, so as to provide a more real pressing experience for learners. The elastic member 31 may be specifically selected as a spring, but may be selected from other elastic members such as a rubber column.

The elastic force sensing member 32 is used to sense the elastic force and the compression amount of the elastic member 31, so the elastic force sensing member 32 can be any element, structure or device having a force sensing function, specifically, a pressure sensor in this embodiment.

The two ends of the elastic member 31 are respectively provided with a pressing plate 33, and the pressing plates 33 are fixedly connected with the ends of the elastic member 31. The pressing plate 33 near the front end can receive the pressing force applied by the learner to the chest position of the dummy 31 and effectively transmit the pressing force to the elastic member 31. The pressing plate 33 near the rear end can bear the elastic force of the elastic member 31 and effectively transmit the elastic force to the elastic force sensing member 32, so as to ensure that the elastic force sensing member can more accurately acquire elastic force data.

The data transmission module 4 is connected to the airflow sensing module 2 and the elastic force sensing member 32, respectively, and functions to generate operation data in response to the airflow data and the elastic force data and output the operation data. The operation data can be directly integrated data containing the air flow data and the elasticity data, and can also be data which is generated after the air flow data and the elasticity data are processed and reflects the operation action of the learner on practicing the cardiopulmonary resuscitation.

The data transmission module 4 can transmit the operation data to an external device, such as a mobile phone, a tablet computer, or other user terminal, or a server of a subordinate hospital or a cardiopulmonary resuscitation teaching institution, so that a teacher can check the result of the learner on practicing cardiopulmonary resuscitation and make corresponding guidance, or the learner can check the result of the learner on practicing cardiopulmonary resuscitation and make corresponding adjustment.

The data transmission module 4 may be any functional module having a data output function, may be a wired data interface of a standard protocol, and transmits the operation data to an external device such as a PC for storage and display through a data line, or transmits the operation data to an external device such as a television for display. The data transmission module 4 may also be a wireless communication module, may be a short-range wireless communication module, such as a bluetooth module, a WiFi module, etc., and may also be a long-range wireless communication module, such as a mobile communication module, etc., and the content of the data transmission module 4 may be set according to the data transmission requirement. In this embodiment, the data transmission module 4 specifically selects a bluetooth module.

In addition, the simulator in the embodiment further includes a data processing module 5, and the data processing module 5 executes a process of receiving the airflow data and the elasticity data and generating operation data according to the airflow data and the elasticity data. Specifically, the data processing module 5 is connected to the airflow sensing module 2, the elastic force sensing element 32 and the data transmission module 4 respectively, so as to connect the data transmission module 4 with the airflow sensing module 2 and the elastic force sensing element 32. The operation data generated by the data processing module 5 includes the pressing depth, the pressing frequency and the blowing frequency. Wherein, the pressing depth is calculated by the elastic force of the elastic member 31 and the stiffness coefficient of the elastic member 31 preset in the data processing module 5, which is embodied by the maximum compression amount of the elastic member caused by a single pressing action; the pressing frequency is determined by the number of times the elastic member 31 is pressed, specifically, the number of maximum values of the curve of the sensed elastic force; the blowing frequency reflects the frequency of blowing the analog human by the learner, the learner generates air flow lasting for a period of time in the blowing air flow channel 11 every time, and the frequency and the number of times of blowing the learner can be obtained by processing the air flow data.

Of course, the operation data may also contain other data reflecting the learner's practicing of the cardiopulmonary resuscitation action, which can be learned from the processing of the air flow data and the elasticity data, such as the duration of a single blow, the blowing speed of a single blow, the duration of a single pressing action, etc., i.e., the content of the operation data may be set by itself as desired.

The data processing module 5 may be specifically selected as an MCU chip, and the MCU chip has a built-in processing logic, which executes the above-mentioned process of generating operation data according to the airflow data and the elastic data, and the logic is conventional, i.e. the present application does not relate to the improvement of the program and the method.
