Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a portable cardio-pulmonary resuscitation audio-visual feedback device and method.
Background
Sudden cardiac arrest refers to the sudden termination of the ejection function of the heart, the disappearance of the aortic beating and heart sound, and the termination of life caused by severe ischemia and anoxia of vital organs (such as the brain). Cardiopulmonary resuscitation is a life-saving technique taken on the heart and breath of a sudden arrest, with the aim of restoring spontaneous breathing and spontaneous circulation of the patient by performing sustained and effective chest compressions.
In 2015, AHA in the United states updated the "guidance on cardiopulmonary resuscitation", and more precise requirements were made on the implementation of chest compressions in cardiopulmonary resuscitation. However, when the requirements of the cardio-pulmonary resuscitation guide are met in clinical work, certain gaps exist, in the cardio-pulmonary resuscitation guide, the infant compression requirement is 4 cm, the child compression requirement is 5 cm, the adult compression requirement and the teenager compression requirement are 5-6 cm, the cardio-pulmonary resuscitation guide emphasizes continuous and effective extrathoracic compression, and the cardio-pulmonary resuscitation guide is rapid, powerful and uninterrupted as much as possible, and can interrupt coronary artery and cerebral blood flow due to excessive compression interruption, so that the resuscitation success rate is obviously reduced. And because the depth of pressing can't be measured in the actual rescue, can appear pressing too deeply or too shallowly, lead to cardiopulmonary resuscitation effect not good, simultaneously in the process of pressing, press the position and can not accurately grasp or press frequency and can not reach standard and cause cardiopulmonary resuscitation effect not good equally.
Currently, devices have been developed that can be used during cardiopulmonary resuscitation to provide a rescuer with corresponding instructions and feedback. These devices are typically placed at the midpoint of the line between the two nipples or in the lower mid-sternum, and when downward force is applied to compress the patient's chest, the device moves as the chest is compressed, by measuring the motion characteristics of the force or acceleration, etc., to determine sufficient compression depth. After measurement, the information is fed back to the rescue personnel through vision or hearing.
However, if the female patient is rescued in public places, the privacy of the patient is easily exposed; when the automatic external defibrillator is used for rescuing, rescuers are required to avoid contacting with patients during electric shock defibrillation, on one hand, the success rate of defibrillation is guaranteed, and on the other hand, the safety of rescuers is protected, but the cardio-pulmonary resuscitation can not be continuous due to the action, and the rescue efficiency is reduced.
The existing cardio-pulmonary resuscitation feedback device does not have an insulation function, can not isolate the defibrillation current generated by an external defibrillator in normal work, protect life safety of rescue workers, and need the rescue workers to timely leave before electric shock, so that the patients are prevented from being touched, and the continuous high-efficiency cardio-pulmonary resuscitation is interrupted. The conventional cardio-pulmonary resuscitation feedback device does not have the function of protecting the privacy of patients, cannot protect the privacy of female patients in public places, and cannot effectively provide corresponding warm-keeping measures for the patients in low-temperature weather.

As shown in figure 1, the portable cardio-pulmonary resuscitation audiovisual feedback device comprises two insulating covering blankets, a presser and an audiovisual feedback device. The insulating covering blanket is used for isolating the current generated by the automatic external defibrillator during electric shock.
The compression device is internally provided with a displacement sensor, measures the compression depth when carrying out chest compression and outputs data. Because the displacement sensor can output different voltage values under different resistors along with the movement of the contact of the displacement sensor, the displacement sensor is in one-to-one correspondence with the displacement, and the accurate relation between the voltage and the displacement is directly defined when the sensor is designed.
The presser transmits the data to the audiovisual feedback device by wired transmission. The audio-visual feedback device comprises a control circuit, a storage module and an output module. The control circuit compares the calculated displacement with a standard displacement range or a threshold value in the storage module, and if the calculated displacement exceeds the set displacement range or is not equal to the threshold value, a corresponding adjusting instruction is given; if the set range has not been exceeded and the thresholds are equal, then there are no adjust instructions.
The output module comprises an indicator light, a loudspeaker and a display screen, and prompts rescue workers to operate more efficiently and normatively through audio-visual modes.
As shown in figure 2, waterproof rectangular insulating covering blankets 1 and 2 are used for isolating AED defibrillation current, protecting privacy of patients and keeping patients warm in low-temperature weather. The built-in displacement sensor of waterproof material presser 3 can be with the chest that records press depth data and pass to audio-visual feedback device 4 through wired transmission, and its lower floor can paste on patient's skin, is convenient for fix the position of pressing.
The audiovisual feedback device 4 comprises an OLED display screen, a loudspeaker, an indicator light and a key. When the startup key is turned on, the audio-visual feedback device guides rescue workers to select the patient type through voice broadcasting, wherein the infant mode pressing requirement is 4 cm, the child mode pressing requirement is 5 cm, and the adult mode pressing requirement and the teenager mode pressing requirement are 5-6 cm.
When the chest compression does not meet the standard, the audio-visual feedback system broadcasts voice prompts of reducing the compression depth, increasing the compression frequency, reducing the compression frequency, continuously compressing and the like, and the voice prompts are usually lighted in red to remind. When the pressing depth and the pressing frequency reach the standard, the audio-visual feedback system stops broadcasting the related voice prompt and turns on the green light constantly.
As shown in fig. 3, the method for audio-visual feedback of cardiopulmonary resuscitation according to the present invention includes the steps of:
(1) pressing a power key, turning on a audition feedback device, and selecting a corresponding patient mode;

(3) the pressing device 3 is positioned at the middle point of the connecting line of the two nipples or the middle-lower part of the sternum, is stuck and fixed, and the two hands are stacked on the pressing device 3 of the feedback device to perform the external chest pressing on the patient;
(4) the displacement sensor measures and calculates the depth of chest compression of the rescue worker, and transmits data to the audio-visual feedback device 4;
(5) the audio-visual feedback device gives corresponding feedback to the rescue workers according to the standard pressing depth and the pressing frequency corresponding to the selected mode;
if the actual pressing depth is lower than the standard pressing depth, the red light is turned on normally, the pressing depth is increased through voice improvement in broadcasting, and relevant standard measures are displayed on the display screen.
If the actual pressing depth is higher than the standard pressing depth, the red light is turned on normally, the pressing depth is reduced through broadcasting improved voice, and relevant standard measures are displayed on the display screen.
If the actual pressing frequency is lower than the standard pressing frequency, the red light is turned on normally, the pressing frequency is reduced through broadcasting the improved voice, and relevant standard measures are displayed on the display screen.
