The following is a more detailed description of embodiments of the invention, taken in conjunction with the accompanying drawings of which:
the intelligent sudden cardiac arrest pulse detection, alarm and first-aid guidance system comprises a processing module 1, wherein the processing module 1 is connected with a storage module 2 used for storing rescue information under the condition of sudden cardiac arrest, an input module 3 used for inputting an operation instruction and an alarm control instruction, a positioning module 4 used for positioning position information, a first pulse measurement sensor module 5 used for detecting that a rescued person has pulse beating, a communication module 6 used for alarming to a 120 center and sending the positioning position information when detecting that the rescued person has no pulse beating, and a display module 7 used for displaying the stored rescue information when detecting that the rescued person has no pulse beating.
The first embodiment is as follows: as shown in fig. 1 and 4, when the system is applied to a smart phone, the control method comprises the following steps:
a. when a rescued person falling to the ground is found, the rescued person can start corresponding APP work through the input module 3, the processing module 1 starts the first pulse measurement sensor module 5 on the smart phone to work, and at the moment, the rescued person respectively detects radial arteries on two sides of the rescued person through the first pulse measurement sensor module 5;
b. the processing module 1 receives the pulse beat information detected by the first pulse measuring sensor module 5 and judges, and when the processing module 1 judges that no pulse beat exists, the processing module 1 alarms to the 120 center through the communication module 6 and sends the positioning position information of the positioning module 4, so that the automatic alarm function is realized, and the ambulance can quickly arrive at the site;
c. meanwhile, when the processing module 1 judges that the rescuer is out of pulse, the display module 7 displays rescue information in the storage module 2, wherein the rescue information is shown in fig. 5 and comprises pictures or videos indicating the pressing position, the pressing depth and the pressing frequency, so that the rescuer is guided to immediately perform free-hand cardiopulmonary resuscitation heart pressing on the rescuer, and the success rate of rescue is improved.
The control method is realized by the aid of APP or WeChat small programs. When being applied to smart mobile phone in the present case simultaneously, processing module 1 is connected with camera module 8, and first pulse measurement sensor module 5 integrates in camera module 8, makes first pulse measurement sensor module 5 hide in camera module 8, need not to change smart mobile phone's appearance and plays the effect of protection first pulse measurement sensor module 5 simultaneously.
Example two:
as shown in fig. 2 and 5, when the system is applied to a sports watch, the processing module 1 is connected to a second pulse measurement sensor module 9 which is provided on the lower side of the sports watch and is in contact with the wrist to detect the pulse of the user, and the second pulse measurement sensor module 9 is a pulse measurement sensor made by the principle of pulse measurement, electrocardiography, or photoplethysmography.
After a user wears the sports watch, when the user is in sudden cardiac death and the second pulse measurement sensor module 9 does not detect the pulse of the user, when the processing module 1 judges that no pulse beats, the processing module 1 alarms to the 120 center through the communication module 6 and sends the positioning position information of the positioning module 4, so that the automatic alarm function is realized and the ambulance can quickly arrive at the scene.
When a rescued person falling over the ground is found, the control method is the same as the first embodiment, and the steps are as follows:
d. the rescuer can start corresponding APP work through the input module 3, the processing module 1 starts the first pulse measurement sensor module 5 on the smart phone to work, and at the moment, the rescuer detects radial arteries on two sides of the rescuer through the first pulse measurement sensor module 5 respectively;
e. the processing module 1 receives the pulse beat information detected by the first pulse measuring sensor module 5 and judges, and when the processing module 1 judges that no pulse beat exists, the processing module 1 alarms to the 120 center through the communication module 6 and sends the positioning position information of the positioning module 4, so that the automatic alarm function is realized, and the ambulance can quickly arrive at the site;
f. meanwhile, when the processing module 1 judges that the rescuer is out of pulse, the display module 7 displays rescue information in the storage module 2, wherein the rescue information is shown in fig. 6 and comprises pictures or videos indicating the pressing position, the pressing depth and the pressing frequency, so that the rescuer is guided to immediately perform free-hand cardiopulmonary resuscitation heart pressing on the rescuer, and the success rate of rescue is improved.
The first pulse measurement sensor module 5 in this case is a photoelectric pulse measurement sensor module, and the photoelectric pulse measurement sensor module includes a light emitting diode that emits a specific wavelength, a photoelectric converter that is used for receiving reflected light and converting the reflected light into an electrical signal, an amplifier that is composed of a low-pass filter and an operational amplifier and is used for amplifying the electrical signal of the reflected light, and a voltage-dividing resistor that divides the voltage of the amplified electrical signal and facilitates the acquisition of the processing module 1.
As shown in fig. 4, the photoelectric pulse measurement sensor module adopts a photoelectric volume method, and the basic principle is to measure the pulse by utilizing the difference of light transmittance caused by the pulsation of blood vessels of human tissues. The sensor used by the device consists of a light source and a photoelectric converter. The light source generally adopts a light emitting diode with a certain wavelength of 500 nm-700 nm which is selective to oxygen and hemoglobin in arterial blood. When light beam penetrates through peripheral blood vessel of human body, the light transmittance of the light beam is changed due to blood congestion volume change of artery pulsation, and at the moment, the light reflected by human body tissue is received by the photoelectric transducer, converted into electric signal, amplified and output. Since the pulse is a signal that changes periodically with the pulsation of the heart and the arterial blood vessel volume also changes periodically, the period of change of the electrical signal of the photoelectric transducer is the pulse rate. According to relevant documents and experimental results, the wave with the wavelength of about 560nm can reflect the information of the arterioles in the shallow part of the skin, and is suitable for extracting pulse signals. The sensor adopts a green light LED with the peak wavelength of 515nm, the model is AM2520, the light receiver adopts APDS-9008, the sensing peak wavelength is 565nm, the peak wavelengths of the two are close, and the sensitivity is higher. In addition, because the frequency band of the pulse signal is generally between 0.05 Hz to 200Hz, the signal amplitude is very small, generally at the level of millivolt, and the pulse signal is easily interfered by various signals. A low-pass filter and an amplifier consisting of an operational amplifier MCP6001 are used behind the sensor, the signal is amplified by 330 times, and meanwhile, a voltage dividing resistor is adopted to set the direct-current bias voltage to 1/2 of the power supply voltage, so that the amplified signal can be well collected by the processing module 1.
