Description
Technical Field
The invention relates to the technical field of medical treatment, in particular to an electrocardio monitoring help-seeking system and method.
Background
The current sudden cardiac death rate in China is 41.84/10 ten thousand, and about 54.4 thousand sudden deaths occur each year. About 75% of these cases are sudden cardiac death, 80% of which are caused by ventricular tachycardia and ventricular fibrillation. The key to rescue such sudden cardiac death is early detection, distress and early initiation of cardiopulmonary resuscitation. The heart of the patient usually begins to generate ventricular tachycardia or ventricular fibrillation before the gold rescue time is 4 minutes, and a coma phenomenon can be generated seriously, so that more people sense danger in the period, the position of the patient is found more quickly, and the earlier rescue such as cardiopulmonary resuscitation and the like for the patient is necessary.
In hospitals, hospitals typically monitor such susceptible patients for 24 hours, which ensures that the condition can be found and treated at the first time. Outside the hospital, the state of illness can only be found by the medical consciousness and knowledge of the user, and the user with lack of medical consciousness often misses the best time for rescue.
For the population with the disease easily occurring, the current solution is to detect whether the patient falls down through falling signal acquisition equipment, if the patient falls down, the GPS inside the equipment can send the position of the patient to a base station, and then the patient contacts a hospital to rescue. Thus, it can be seen that location positioning and finding of the user with the onset of disease is very important. However, since the positioning is performed by using the GPS, the positioning accuracy of the GPS is about 10 to 200m, and therefore, the positioning cannot be performed indoors. The positioning is also performed by adopting a communication base station, but the positioning accuracy mainly depends on the density of the base station, and the positioning accuracy has great fluctuation. In addition, as can be seen from the above process, after the patient is ill, the hospital is notified, and the hospital needs to spend a lot of manpower and material resources for positioning and searching, so that the medical burden is increased, and the death rate of the patient is not reduced significantly. Therefore, it is necessary to develop an efficient and accurate-positioning system for monitoring and asking for help for cardiac electric monitoring.

In order to better understand the electrocardiographic monitoring distress system of the present invention, a few examples are set forth in detail below.
Example 1:
example 1 with the electrocardio acquisition module the signal analysis module first iBeacon signal module is set up respectively in different equipment for the example elaboration. For example, the electrocardio collection module sets up in portable electrocardio collection device, signal analysis module with first iBeacon signal module all is set up in portable handheld device, promptly signal analysis module with first iBeacon signal module is not restricted to and is set up in portable electrocardio collection device, also can set up in portable handheld device, for example cell-phone or portable computer, through portable handheld device with carry out information interaction between the electrocardio collection module to acquire the electrocardio signal by monitoring user, and then judge whether user's electrocardio state exists unusually.
Referring to fig. 2 and 3, fig. 2 is a schematic view of a communication architecture of the central electrical monitoring distress system in the embodiment; fig. 3 is a flowchart of the operation of the central electricity monitoring and help-seeking system in this embodiment. The electrocardio collection module is set up in a signal acquisition equipment (for example, the electrocardio pastes), signal analysis module with first iBeacon signal module is set up in a transfer equipment, second iBeacon signal module with distress alarm module sets up in at least one receiving equipment (including receiving equipment 1 in FIG. 2, receiving equipment 3, … receiving equipment n, n is the positive integer), because first iBeacon signal module the existence of second iBeacon signal module makes transfer equipment with receiving equipment all is the supporting iBeacon agreement, can realize the propelling movement and the receipt of low-power consumption bluetooth instruction each other. In practical application, the specific working flow is as follows: the signal acquisition equipment is worn on the body surface of a monitored user close to the heart, the signal acquisition equipment detects electrocardiosignals, the transfer equipment receives and judges the abnormal electrocardio state, when the abnormal electrocardio state exists, the transfer equipment sends an iBeacon distress command, the receiving equipment confirms that the iBeacon distress command is received, the receiving equipment feeds back the iBeacon confirmation signal, and after the transfer equipment receives the iBeacon confirmation signal, the distance between the transfer equipment and the receiving equipment is calculated, the position information of the transfer equipment is calculated according to the distance, the position information is sent to the receiving equipment, the receiving equipment receives the position information, the position of the transfer equipment is searched and positioned according to the position information, and the monitored user is rescued.
In order to reduce in the transfer equipment the work load of first iBeacon signal module, the electrocardio monitoring SOS of this example still includes a big data processing platform, is used for obtaining the distance information between each receiving equipment and the transfer equipment specially, thereby calculates the position of transfer equipment (being equivalent to the position of first iBeacon signal module), guides each receiving equipment according to the position information search location of transfer equipment the transfer equipment.
Specifically, fig. 4 is a schematic structural diagram of the signal acquisition device in this example. As shown in fig. 3 and 4, the signal acquisition apparatus includes: the electrocardiogram signal acquisition module acquires an electrocardiogram signal, the gesture detection module acquires a three-dimensional acceleration signal, and the wireless transmission module receives and transmits the electrocardiogram signal and the three-dimensional acceleration signal. The transfer device includes: the Bluetooth module (namely the first iBeacon signal module) and the application software module (comprising a signal analysis module) support the iBeacon protocol; the application software module includes but is not limited to IOS or Android based software programs; the Bluetooth module sends the received electrocardiosignals and the three-dimensional acceleration signals to the application software module, an electrocardio algorithm is embedded in the application software module, the electrocardiosignals and the three-dimensional acceleration signals transmitted by the signal acquisition equipment in real time are calculated through the electrocardio algorithm, the calculation result is analyzed to judge whether the electrocardio state of the monitored user is abnormal, and when the electrocardio state is abnormal, help seeking information is pushed to the at least one receiving equipment. For example: when the heart of the monitored user has ventricular fibrillation or falls down, the application software module pushes help information outwards. Each receiving device comprises a Bluetooth receiving module (namely a second iBeacon signal module) supporting the iBeacon protocol and an application software module (comprising an alarm help-seeking module); the Bluetooth receiving module receives help seeking information pushed by the transfer equipment, the application software module analyzes the help seeking information, and the distance between the receiving equipment and the transfer equipment is calculated when the mark of the transfer equipment is matched with the mark of the receiving equipment.
In this example, the help-seeking information is a BLE instruction (bluetooth low energy instruction), a format of the BLE instruction is unified by iBeacon, and data constituting the BLE instruction mainly includes the following four parts: UUID, Major, Minor, Measured Power. UUID is specified as ISO/IEC 11578: the 1996 standard 128-bit identifier to point to each specific device, each device would be assigned a unique UUID for tagging; major and Minor are 16-bit fields, which can be configured by the developer. For example, Major is set for identifying a specific mark, and Minor is set for identifying the age or gender or other characteristics of the monitored user, so that the audience can quickly know the basic information of the monitored user, and the audience searching is facilitated. Measured Power is the reference received Signal Strength at a distance of 1 meter between the relay device and the receiving device, and is called rssi (received Signal Strength indicator).
In this embodiment, the bluetooth module supporting the iBeacon protocol is used to acquire the RSSI information, so that the distance between the relay device and the receiving device is calculated based on the acquired RSSI. The correlation calculation formula is as follows:
d, transferring the distance between the equipment and the receiving equipment; pr is the received power; pt is the emission power; gt and Gr are the gain of the transmitting antenna and the gain of the receiving antenna respectively; λ is the wavelength of the electric wave; the units of Pt and Pr are watts; gt and Gr are dimensionless. From this equation, the Pr received power is inversely proportional to the distance d2 in free space.
The RSSI is in dBm, and d0 is generally 1.
In general indoor positioning, considering factors such as environment, cost and positioning accuracy requirements, the used RSSI ranging signal attenuation model is further simplified as follows:
RSSI＝A-10nlog10d
wherein d is the distance between the transfer equipment and the receiving equipment, and the unit of d is m; a represents the signal strength at 1m from the sender; RSSI is the measured signal strength of the receiving device at its current location in dBm.
Please refer to fig. 5, which is a schematic diagram illustrating that when the number of the receiving devices is 1, the receiving devices search and locate the monitored user. Since iBeacon can support signal reception in a range of 30 meters, an area of 2800 square meters can be covered at the most. Therefore, after the receiving device supporting the iBeacon protocol finds help seeking information pushed by the transfer device supporting the iBeacon protocol, the user holding the receiving device can rapidly get close to the monitored user (i.e., a patient suffering from a disease), if the direction is wrong, the receiving device can display a state of getting farther and farther away from the monitored user, and prompt the user, such as position 1-position 2 in fig. 4, and the user holding the receiving device can adjust the direction in time and get close to the monitored user, such as position 3-position 4 in fig. 4. On the premise that the number of the receiving devices is one, the accuracy range of the positioning of the monitored user is 3m-5m, and the user can be found within the range of vision.
Please refer to fig. 6, which is a schematic diagram illustrating the searching and positioning of the monitored user by the receiving device when the number of the receiving devices is 3 in the present embodiment.
