Description

Technical Field

[0001] The utility model relates to the field of medical rescue instruments, in particular to a cardiopulmonary resuscitation simulator. Background Art

[0002] Cardiopulmonary resuscitation is a series of life-saving measures to improve the survival chance after cardiac arrest. At present, the popularization rate of cardiopulmonary resuscitation first aid knowledge in China is very low. Many people are at a loss when faced with a cardiac arrest patient except calling 120. Once cardiac arrest occurs, if not rescued and resuscitated immediately and in time, irreversible damage to the patient's brain and other important human organ tissues will occur after 4 - 6 minutes. Therefore, it is quite important to popularize cardiopulmonary resuscitation first aid knowledge.

[0003] Currently, there is cardiopulmonary resuscitation training organized by the Chinese Red Cross Society for sports enthusiasts or volunteers. It is mainly guided by medical practitioners, carrying a human model, and conducting a simple 2 - 3 - day training and learning through on - site demonstration. The main purpose is to familiarize with the first aid process and essentials. Limited by the training time, in the cardiopulmonary resuscitation training and assessment, only the basic process and movement essentials can be initially evaluated, and the rhythm, strength, etc. of cardiopulmonary resuscitation cannot be effectively assessed.

[0004] Therefore, a cardiopulmonary resuscitation training device and evaluation system are needed, which can not only meet the cardiopulmonary resuscitation training of the learning population, but also guide the cardiopulmonary resuscitation operation process and the operation standards of each process, timely remind and correct the errors that occur during the training process. In addition, the evaluation system is based on the cardiopulmonary resuscitation operation specification standards to meet the needs of automatic assessment of cardiopulmonary resuscitation assessment, and better helps the scorers evaluate whether the operator's operation actions meet the standards. Summary of the Invention

[0005] The purpose of the utility model is to solve the above problems and provide a standard, reasonable and intelligent cardiopulmonary resuscitation simulator.

[0006] The technical solution of the utility model is as follows:

[0007] A cardiopulmonary resuscitation simulator, including a simulation human body and a real - time display device. The simulation human body includes an air flow channel connected to the oral cavity, and an air flow bag is provided at the position extending downward to the chest cavity, which is used to simulate the chest swelling during blowing. A blowing sensor is arranged in the air flow channel to measure the air flow velocity, and the blowing sensor is connected to a micro - processor;

[0008] A pressing distance - measuring sensor is arranged at the chest cavity position of the simulation human body. The two ends of the sensor are respectively connected to the front end and the rear end of the chest cavity position. The pressing distance - measuring sensor is sequentially connected to a data converter and a micro - processor, and the measured pressing data is displayed as the real pressing value through the real - time display device; the detected value is the real pressing value, not an analog quantity, which solves the possible errors and distortions in the analog quantity;

[0009] The single-chip microcomputer is connected to the host computer through a custom communication protocol, and the real-time display device is connected to the host computer through the network.

[0010] The real-time display device mentioned above adopts a tablet device. This tablet device is equipped with a built-in camera and is connected to the host computer through the network. The built-in camera shoots and records the video of the operator performing cardiopulmonary resuscitation on the mannequin. It recognizes the human body posture through the built-in camera and receives and records the sensor data, gives and exports statistical reference data. The assessors can also synchronously record the on-site data through other tablets or video recording devices.

[0011] The tablet device can recognize the human body posture of the assessors and trainees. The recognized data is transmitted to the host computer and matched and displayed with the data of the simulated blowing and pressing sensors, which can intuitively display the operation status of the cardiopulmonary resuscitation simulator and can also be played back for convenient scoring and correction.

[0012] In terms of data, the single-chip microcomputer and the host computer acquire and process the data from the sensors, and use multiple algorithms such as the pressing depth extraction algorithm, the pressing frequency extraction algorithm, the pressing time extraction algorithm, the pressing number extraction algorithm, the rebound number extraction algorithm, and the blowing volume extraction algorithm to process the eigenvalue data.

[0013] Advantages of the utility model

[0014] This solution can improve the accuracy of cardiopulmonary resuscitation simulation training, can display and record in real time, which is convenient for on-site assessment reminders and remote guidance, and is conducive to the popularization of cardiopulmonary resuscitation first aid knowledge; the mannequin body and the real-time display device can adopt built-in power supplies, reducing cable layout, with a simple structure and being easy to move.
