Description

Physiological information monitoring system

The present invention relates to a monitoring system, particularly a physiological information monitoring system that can be installed on the human body to detect physiological information and effectively utilizes relay hardware to transmit the detected physiological information.

Physiological information refers to information about the state of the human body, including heart rhythm, blood pressure, body temperature, respiratory rate, blood oxygen concentration and other data. Monitoring physiological information can help people understand their physical status and detect potential health problems in time so that early measures can be taken. Modern technology provides a variety of ways to monitor physiological information, such as smart bracelets, health mobile apps, smart wearable devices, etc., which collect and analyze physiological information through sensors and algorithms. These tools can help people monitor their physical status and detect abnormal physiological indicators in time so that corresponding adjustments and treatments can be made.

In terms of heart rhythm detection, from the past, short-term heart rhythm detection had to be carried out on large machines in hospitals, to now, long-term heart rhythm detection can be done remotely at home. The advancement of technology is reflected in the innovation of heart rhythm monitoring equipment and the technology of transmitting information without leakage. of completeness. These heart rhythm monitoring devices, like traditional heart rhythm detection machines, need to install detection electrodes on the body as widely as possible. The difference is that these innovative heart rhythm monitoring devices can directly or indirectly transmit the detected signals to the remote analysis platform through wireless transmission through relay devices, thereby achieving continuous tracking and real-time detection of health problems. The highly effective yet low-cost design benefits many people suffering from long-term cardiovascular disease. In addition, since the data is transmitted in real time, the remote analysis platform can also issue monitoring reports on time or deduce potential heart-related diseases based on the monitoring content, allowing people to prevent them in advance.

However, where the technology lies, there is also the difficulty. During the data transmission of the aforementioned heart rhythm monitoring equipment, a large number of detection values are often accumulated many times in one batch. Transmission via packets can easily be lost in high-noise environments, requiring supplementary transmission or even retransmission of previous data, which is very time-consuming and time-consuming. Therefore, many technologies are working hard to improve the existing problems in the technology of wireless transmission of data from heart rhythm monitoring equipment. For example, U.S. Patent No. 9,597,004 proposes a wearable device for monitoring data that uses a transmitter configured to send a heartbeat time series to a computing device when the user triggers the device based on a perceived cardiac event. , a computing device configured to infer from a time series of heartbeats the likelihood of a past arrhythmia occurring. This invention focuses on detecting and transmitting heart rhythm data when a cardiac event occurs. Although the amount of data transmitted is small, this invention cannot provide health monitoring services for patients and uses extreme values (data when a cardiac event occurs) to make inferences. The effectiveness of past conditions also needs to be verified. In addition, U.S. Invention Patent No. 8301236 proposes a system for patients with access to cellular networks. The system consists of a body sensor device, a handheld device, a data center and a monitoring center. The handheld device receives and stores body electrocardiogram data from the body sensor device and will send packetized signals via the cellular network that include the fully disclosed electrocardiogram data stored in the handheld memory. The data center stores the packetized signals of the fully disclosed ECG data included in the received data and analyzes the stored fully disclosed ECG data to identify any anomalies therein. Finally, doctors can use the monitoring center to view technician reports provided by the data center and view fully public ECG data stored in the data center, so that the system can telemetry fully public ECG data and related reports from a remote location. However, this invention does not mention reducing the amount of transmitted data of human electrocardiogram data.

Since there is no system architecture in the prior art that can continuously detect, transmit, and analyze human physiological information with a small amount of detection data, the present invention is proposed.

According to the present invention, if the recording transmitter detects that the transmission channel noise is greater than a certain value and affects data transmission, the data transmission is suspended until the transmission channel noise is less than the fixed value.

According to the present invention, an analysis system is installed in the data analysis equipment and a user interface is provided. The user can access, interpret and modify the analysis data, and classify and mark physiological abnormality information through the user interface. .

According to the present invention, the data analysis device utilizes the analysis system to arrange the batches of integrated data in time-stamped order to form the restored physiological information that is close to the physiological information.

The fixed monitoring module of the present invention obtains a recorded value of the potential of the human body surface representing a physiological information. The recording transmitter decrements the recording values and transmits them to the data analysis equipment through the transceiver acting as a relay. Data analysis equipment restores all recorded values. In this way, the present invention can continuously detect, transmit and analyze human physiological information with a smaller amount of detection data.

In order to make the description of the disclosure more detailed and complete, an illustrative description is provided below for implementation modes and specific examples of the present invention.

Please refer to Figure 1, which is a schematic diagram of components and application scenarios of a physiological information monitoring system 1 according to an embodiment of the present invention. The physiological information monitoring system 1 includes a fixed monitoring module 10, a recording transmitter 20, a transceiver 30 and a data analysis device 40. The types, functions and interactions of these technical components will be explained in detail below.

Please see Figures 2 to 4. Figure 2 is a three-dimensional view of the fixed monitoring module 10 and the recording transmitter 20 when combined. Figure 3 is a three-dimensional view of the fixed monitoring module 10 and the recording transmitter 20 when they are separated. Figure 4 is a fixed monitoring Exploded view of Module 10. The fixed monitoring module 10 includes a combination base 11 , a flexible planar substrate 12 , a detection circuit 13 and two pieces of release paper 14 . The coupling base 11 is an object made of hard material, such as skin-friendly plastic, and is used to detachably couple with the recording transmitter 20 and guide the coupling of the conductive lines between the coupling base 11 and the recording transmitter 20 . The central part of the coupling base 11 is a plate-like structure, and a plurality of curved extensions 111 are formed at its edges, extending outward and upward from the plate-like structure to clamp the recording transmitter 20 . The flexible planar substrate 12 is the main body for connecting the components of the fixed monitoring module 10 and is also used for detachable bonding with the human body. The flexible planar substrate 12 is made of a synthetic fiber material, which may be polypropylene, polyethylene, polystyrene, polyurethane, polyvinyl chloride, etc. A first side (the back side in FIG. 4 ) of the flexible planar substrate 12 has a first skin-friendly adhesive layer to adhere to the user's body surface. The first skin-friendly adhesive layer is formed by coating and curing acrylic adhesive. The flexible planar substrate 12 has several openings 121 , in this embodiment there are two, and the openings 121 are designed for the detection circuit 13 to come into contact with human skin. The detection circuit 13 is installed on a second side (the back side of the first side) of the flexible planar substrate 12, and consists of several waterproof wires 131 (disposed in the fixed film 134, indicated by dotted lines), respectively connected to each waterproof wire. Several sensing electrodes 132 connected to one end of 131 (one side of the reverse page is covered by a fixed film 134, represented by a dotted line), a signal assembly 133 that collects the other end of each waterproof wire 131, and partial covering It is composed of a fixed film 134 of the aforementioned components. The waterproof wire 131 electrically connects the sensing electrode 132 and the signal assembly 133, so that the contact point in the signal assembly 133 connected to the waterproof wire 131 maintains the same potential as the sensing electrode 132 (skin). The signal assembly 133 collects one end of all the waterproof wires 131 and connects them to the conductive terminals 1331 respectively, and then is detachably connected to the input and output contacts of the recording transmitter 20, so that the input and output contacts are also connected to the waterproof wires. 132 maintains a consistent potential. Each sensing electrode 132 faces the corresponding opening 121 and contacts the user's body surface through a second skin-friendly adhesive layer. In addition to being able to effectively bond with the user's surface skin, the second skin-friendly adhesive layer also needs to be conductive. According to the present invention, the second skin-friendly adhesive layer is a layered structure formed of hydrogel. The release paper 14 is attached to the first skin-friendly adhesive layer to protect the first skin-friendly adhesive layer, and is removed when the fixed monitoring module 10 is to be fixed on the skin.

The recording transmitter 20 is a portable electronic device that is detachably combined with the fixed monitoring module 10 and adhered to the user's body surface through the fixed monitoring module 10 to further process the data transmitted from the fixed monitoring module 10 Signal (potential change at each conductive terminal 1331). In terms of hardware, the recording transmitter 20 includes a protective case 21 and a signal processing circuit 22 inside the protective case 21 . Please see Figure 3 again. In this embodiment, the protective housing 21 has the appearance of a rectangular housing with eight rounded corners. The rounded corners can be clamped on the curved extension 111 of the coupling base 11 , so that the protective housing 21 is detachably connected to the fixed monitoring module 10 . In addition, several input and output contacts 224 of the signal processing circuit 22 can be electrically connected to corresponding conductive terminals 1331 on the signal assembly 133 to transmit signals from the fixed monitoring module 10 to the signal processing circuit 22 . Therefore, the recording transmitter 20 is electrically connected to the signal assembly 133 and the user's body surface.

Please refer to FIG. 5 , which is a component block diagram of the signal processing circuit 22 . The signal processing circuit 22 includes a processor 221, a storage module 222, a wireless transmission module 223, the aforementioned input and output contacts 224 and a power module 225. The processor 221 is the core component of the signal processing circuit 22. The processor 221 can continuously obtain several recorded values of the body surface potentials sensed by the sensing electrodes 132 as a heart rhythm information and store it in the storage module 222. In this embodiment, the body surface potential is represented as an electrocardiogram signal, and the several recorded values are each value that describes the change of the electrocardiogram signal on the time axis to form corresponding heart rhythm information, and two adjacent values among the several recorded values The time intervals between values are the same. Please see Figure 6. This figure illustrates the method of obtaining integrated data from heart rhythm information. The upper half of the figure represents the composition of the heart rhythm information. In the upper half of the figure, as time increases on the time axis, the time points go from T1, T2,... to T15, and the intervals between two adjacent time points are the same. The body surface potential value at each time point, such as mV, is expressed in column length. The collection of data at all time points is the heart rhythm information. In Figure 6, an envelope line is used to represent the heart rhythm information, which may actually be a person's heart rhythm beating curve. The recording transmitter 20 should transmit the values of this line to the outside with minimal distortion. It can also be seen from FIG. 6 that the integrated data arranged in time stamp order and the heart rhythm information have consistent pulse frequency changes, which will not cause waveform mismatch when the data analysis device 40 performs the restoration operation. For example, In other words, the signal pulsation frequency of the heart rhythm information between times T1 and T15 changed from 5Hz to 10Hz and then to 1Hz, and the signal pulsation frequency of the integrated data between T1 and T15 also changed from 5Hz to 10Hz and then to 1Hz. , both have consistent changes in pulsation frequency. It can also be said that the restored physiological information and the heart rhythm information or the integrated data formed by the data analysis device 40 have consistent changes in pulsation frequency. In practice, it is not impossible for the recording transmitter 20 to completely transmit all the heart rhythm information at one time, but the large amount of data (high sampling frequency) will cause possible delays or even loss in transmission, so reduced data transmission is adopted. What the processor 221 does is to take out the recorded values in the heart rhythm information every N times to form several integrated data and send out the integrated data and a related time stamp, where N is a positive integer other than 1. Preferably, N is a positive integer other than 1 and less than or equal to 10, in order to gain focus and retain appropriately interpretable integrated data. On the other hand, the method of sending the integrated data and time stamps can be scheduled, for example, every 10 minutes. In this embodiment, N is taken as 2, that is, starting from the first body surface potential value, odd time points are taken, such as the body surface potential values at T3 and T5 as the integrated data, that is, the selected body surface potential value is a Integrate data. When several pieces of integrated data are sent out, compared to the complete output of heart rhythm information, the amount of data in the former is only half of the latter. In the same way, if N is set to 3, the total amount of data transmitted is about one-third of the complete heart rhythm information. Since the receiver is required to confirm the order of each transmission, in order to prevent the receiver from being able to confirm which one is first and last when a supplementary transmission is required due to loss, the integrated data of each transmission must be time stamped. According to the present invention, the time stamp includes the earliest and latest times of the integrated data records, such as the times T1 and T15 in Figure 6. In addition, the time stamp can also be a sequence number representing the integrated data records, as shown in Figure 6. T1 to T15 in order. According to the present invention, the storage module 222 includes a temporary memory 2222 (such as a random access memory, RAM) and a permanent storage memory 2221 (such as a flash memory, Flash Memory). The heart rhythm information is stored in the permanent storage memory 2221, and the integrated data is stored in the temporary memory 2222. After the current integrated data is sent, the temporary memory 2222 is cleared so that new integrated data can be formed and stored. Preferably, information related to user identification can be added for transmission, such as a user serial number pre-stored in the permanent storage memory 2221.

According to the present invention, the record transmitter 20 can compress the integrated data and the related time stamps each time before sending them. The receiving end, such as the data analysis device 40, after receiving the compressed integrated data and the related time stamps, will or decompress. Compressing integrated data and time stamps can further reduce the amount of data transmitted and save transmission power consumption. As for which compression technology is used, the present invention is not limited. The function of the recording transmitter 20 is not only to perform data reduction transmission, but also to preliminary analyze the heart rhythm information to determine whether there is a possibility of potential disease. The processor 221 of the recording transmitter 20 can further determine the pulsation condition of the heart rhythm information. If the heart rhythm information continues to pulsate abnormally within a sustained period of time, such as one pulse cycle (for example, the pulse condition deviates significantly from that of a normal person), the processor 221 That is, a significant message is sent, and the integrated data and the corresponding time stamp are sent. Distinctive information includes an out-of-phase description of the pulsation condition (e.g., represented by a code or written directly). In addition, the processor 221 also interprets the significant message, integrates the data and the corresponding time stamp to identify abnormal heart rhythms, and can also perform real-time tracking of physical problems manifested by the integrated data sent during a certain period. If the data is transmitted several times in a row, There is obvious information, which means that the subject tested may really have a certain disease and the symptoms are obvious. Since the processor 221 is programmable and editable, significant messages may not be sent every time when an abnormality is detected, but may be sent every fixed time (for example, every 5 minutes). Sometimes, only one abnormal situation occurs within the duration, or the abnormal situation may occur intermittently, or even the abnormal situation disappears after a short period of time. The processor 221 can also choose to issue a significant signal when an abnormal situation occurs according to the settings. message, or a significant message must be issued when a certain degree of abnormality occurs within the duration (for example, the occurrence of abnormality accounts for more than 50% of the delay period). In addition, the extension time can generally be no more than 1 minute to avoid delaying the warning of abnormal situations.

The wireless transmission module 223 is a processing device that records data transmission and reception between the transmitter 20 and the transceiver 30. Its specifications must match the wireless transmission and reception module of the transceiver 30, such as using Bluetooth or Wi-Fi specifications for data transmission and reception. When the wireless transmission module 223 of the recording transmitter 20 detects that the transmission channel noise is greater than a certain value and affects data transmission, the data transmission can be suspended until the transmission channel noise is less than the fixed value. The aforementioned setting values can be adjusted according to the environment or application. The main function of setting the channel noise limit is to prevent data transmission loss and the trouble of repeated transmission. The input/output contacts 224 are metal contacts used for electrical signal connection with the corresponding conductive terminals 1331 . The power module 225 includes a battery (which can be a secondary battery or a primary battery) and a power distribution circuit, which can supply power to electrically connected components according to demand for normal operation. In FIG. 5 , the electrical connections between the power module 225 and other components are represented by dotted lines. The recording transmitter 20 is a reusable device. After the monitoring is completed, the fixed monitoring module 10 is replaced and attached to the body surface of another user for new monitoring.

Since the transmission power of the recording transmitter 20 is not high and its main function is to process the signals from the fixed monitoring module 10, the transceiver 30 is used as a relay to further transmit the signals to the data analysis device 40. The transceiver 30 is signally connected to the recording transmitter 20 to receive and wirelessly transmit the integrated data, time stamps and/or significant messages from the recording transmitter 20. On the other hand, the transceiver 30 receives and wirelessly transmits the integrated data. The method can be continuous. The transceiver 30 can contact the recording transmitter 20 and trigger the recording transmitter 20 to send the integrated data and time stamp. Alternatively, the transceiver 30 can also adjust or limit the sending conditions of the recording transmitter 20, such as the sending frequency or the amount of data sent, which is a setting method according to specific requirements.

In practice, the transceiver 30 may be, but is not limited to, a special electronic device, a cloud system device, a mobile phone with auxiliary applications installed, a tablet computer or a personal digital assistant device. As mentioned above, the data transmission between the recording transmitter 20 and the transceiver 30 can comply with Bluetooth, LTE, WiFi or data serial port connection transmission protocol, so the transceiver 30 can read an identity tag of the recording transmitter 20 . The identification tag may be the production serial number or MAC Address of the record sender 20 . In this way, in a space where several recording transmitters 20 are used simultaneously, the transceiver 30 can continuously track the data sent by the same recording transmitter 20 without confusing different sources.

The data analysis device 40 is a device ultimately used to analyze the integrated data from the recording transmitter 20 and provide analysis results. In practice, the data analysis device 40 may be a server. The data analysis device 40 and the transceiver 30 are information-connected to the transceiver 30 through the network 2, relaying access to the integrated data, performing a restoration operation on the integrated data to obtain a restored physiological information, and processing the integrated data An automatic operation is performed to obtain analysis data including physiological abnormality information. Please see Figure 7, which illustrates the method of generating restored physiological information from integrated data reduction. The chart at the top of Figure 7 is the same as the chart at the bottom of Figure 6, showing the integrated data sent by the recording transmitter 20 in one batch. According to the present invention, the reduction operation can be any method of estimating possible values at any time between two integrated data values. For example, the restoration operation is to use interpolation to fill in some of the recorded values of the heart rhythm information that are missing from the integrated data to form restored physiological information. As shown in the bottom of Figure 7, after using the interpolation method, the values of even time points T2, T4...T14 can be obtained, which are displayed in dotted columns. By connecting the tops of all columns with dotted lines, another restoration envelope can be obtained. Although the restored envelope is slightly different from the original envelope (shown as a solid line), the heart rhythm pulses expressed by the two are consistent. Automatic calculation is a program that interprets the integrated data and classifies and marks normal or abnormal heart rhythm information. It can be classified and marked by comparing with several normal or abnormal patterns preset in the data analysis device 40 . Preferably, the automatic calculation interprets the integrated data through a machine learning model and classifies and marks normal or abnormal heart rhythm information.

Preferably, an analysis system can be installed in the data analysis device 40 and provide a remote user interface with the data analysis device 40 through the network 2 and the client 50 . Users can access, interpret and modify the analysis data, as well as classify and mark physiological abnormality information through the user interface. This approach can facilitate the doctor to use the user terminal 50 to conduct remote symptom analysis on the patient's analysis data, so that the patient can be notified immediately of the occurrence of heart rhythm disease or prevent the heart rhythm disease in advance. In addition, the data analysis device 40 utilizes the analysis system to arrange the integrated data of each batch in time-stamped order to form restored physiological information that is close to real physiological information.

If a mobile phone with an auxiliary application installed is used as the transceiver 30, since the mobile phone can also provide additional data processing and storage functions, the transceiver 30 can also be set to confirm whether any batch of integrated data is missing and seek compensation. Qi. According to the present invention, each integrated data and the corresponding time stamp can be stored in the transceiver 30 . If the data analysis device 40 finds that there is a missing part of the integrated data, it will take out the time stamps of the integrated data before and after the missing part and then transmit it to the transceiver 30 . The transceiver 30 compares all time stamps according to the two time stamps, finds out the heart rhythm information part corresponding to the missing integrated data, regenerates a supplementary data, and wirelessly transmits the supplementary data together with the corresponding time stamps, for example, to Data analysis equipment 40. The data analysis device 40 fills in the missing part with the supplementary data.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some modifications and modifications without departing from the spirit and scope of the present invention.
