detailed description

Hereinafter, the preferred embodiments of the present invention will be further described with reference to the drawings.

Please refer to FIG. 1 first. FIG. 1 is a schematic block diagram of a preferred embodiment of a physiological monitoring system using a Bluetooth Low Energy MESH Network (BLE MESH NETWORK) of the present invention.

As shown in FIG. 1 , the physiological monitoring system using Bluetooth low power mesh network of the present invention includes a main control device 200 , multiple physiological detection devices 110 , 120 , a fixed-end Bluetooth low power transmission device 300 and a cloud database 400 . Wherein, the main control device 200 includes a main control end Bluetooth low power transmission module 220 , a data processor 210 , a warning device 230 and a physiological data evaluation unit 240 which are electrically connected to each other. Physiological detection devices 110, 120 respectively include peripheral Bluetooth low power transmission modules 112, 122 electrically connected to each other, detection processors 111, 121, physiological sensors 113, 123, voice input and output devices 114, 124 and input device 115 , 125. In addition, the monitoring system also includes a fixed-end Bluetooth low-power transmission device 300 .

The basic operation of the physiological monitoring system of the present invention is described below. As shown in FIG. 1 , the physiological monitoring system of the present invention can be applied, for example, to a medical care center. Different from the existing method of measuring the patient's physical values by personnel personally going to the ward, in the case of using this system, when the medical staff wants to measure the physiological value of the patient, the medical staff can use the main control device 200 installed in the nursing station, For example, the computer in the nursing station sends out the measurement instruction signal A. The measurement instruction signal A is generated by the data processor 210 , and then the measurement instruction signal A is broadcast to the outside through the Bluetooth low power transmission module 220 of the master control end. Afterwards, the broadcasted measurement instruction signal A can be received by multiple physiological detection devices 110 and 120 via the fixed-end Bluetooth low-power transmission device 300 , or multiple physiological detection devices 110 and 120 can be directly received by the main control device 200 and broadcast The measurement command signal A. Each physiological detection device corresponds to a subject. In particular, the wireless medical network applied to the medical care center must meet the standards of low power and low radio frequency interference in signal transmission, so the physiological monitoring system of the present invention uses a low-power bluetooth mesh network for the main control device and physiological detection Signal transmission between devices and when the distance between the main control device and the physiological detection device is relatively long, a fixed-end low-power Bluetooth transmission device 300 is added to expand the range of signal transmission and the stability of the transmitted signal.

In a preferred embodiment, the measurement instruction signal A includes a voice driving signal E, and the physiological detection device 110 includes a preset voice information. The measurement command signal A is received by the physiological detection device 110 and sent to the detection processor 111 . The detection processor 111 drives the voice input and output device 114 , such as a speaker, to play preset voice information according to the voice driving signal E of the measurement instruction signal A. The content of the voice may be an inquiry from the medical personnel, for example, asking the subject whether to perform blood pressure detection. After hearing the voice, the subject can input a reply command F to the physiological detection device 110 through an input device 115 , such as a touch display. The reply instruction F is sent to the detection processor 111 , and the detection processor 111 judges whether to send the measurement instruction signal A to the physiological sensor 113 according to the reply instruction F. In detail, when the reply command F is “No” or no reply command F is generated, the detection processor 111 does not perform the measurement of the physiological signal. If the reply command F is “yes”, the physiological sensor 113 performs physiological detection of the subject and returns the detected physiological value B1 to the detection processor 111 . Next, the detection processor 111 generates a physiological data signal C1 according to the physiological value B1 and the identification code of the physiological detection device 110 , and the peripheral Bluetooth low power transmission module 112 broadcasts the physiological data signal C1 to the outside.

The transmission of voice information provided by this embodiment and the mechanism for the subject to input a reply command can make the subject know that a detection action will be performed on himself, and he can choose whether to accept the test. This increases the safety of the physiological monitoring system of the present system. For example, during the process of blood pressure detection, the air bag covering the subject's arm/wrist will be inflated for blood pressure detection. This procedure compresses blood vessels, which may cause discomfort. If the subject judges that his physical condition at that time is not suitable for testing, or the situation at that time is not suitable for testing, he can pass the decision of rejecting the test by inputting the reply command. Avoid the harm caused by the subject being tested in an uncomfortable situation.

Next, the operation process after the physiological data signals C1 and C2 are received by the main control device 200 will be described. The physiological data signals C1 and C2 are transmitted to the data processor 210 after being received by the Bluetooth low power transmission module 220 of the main control device 200 . The data processor 210 generates a medical record table 211 corresponding to the subject according to the physiological data signals C1 and C2. The medical record table 211 includes a device address field 211a and a physiological value field 211b. Wherein, the data processor 210 records the identification codes of the physiological detection devices 110 and 120 in the device address column 211a according to the received physiological data signals C1 and C2, and records the physiological values B1 and B2, such as blood pressure, heart rate or The body temperature is recorded in the physiological value column 211b corresponding to the identification code of the physiological detection device 110 , 120 . In detail, the device address column 211a is the subject corresponding to the physiological testing device 110, 120, and the identification code of the physiological testing device 110, 120 in the device address column 211a can be the IP address of the physiological testing device. The name of the measured subject is used to generate the medical record table 211 of the subject corresponding to each physiological detection device. Finally, the medical record table 211 can also be stored in the cloud database 400 .

As mentioned above, the physiological monitoring system of this system automatically collects the physiological data signals of each subject through the low-power bluetooth mesh network. In this way, the measurement process can be quickly completed and the medical record form can be automatically generated to reduce the human resources of medical staff, improve the efficiency of medical care, and reduce the possibility of human error.

In addition, the physiological detection devices 110, 120 of this embodiment further include detectors 116, 126 and near field communication tags (NFC Tag) 117, 127, and the detectors 116, 126 are electrically connected to the detection processor 111 , 121, used to detect whether the physiological detection device 110, 120 is out of the set position. For example, the physiological detection devices 110 and 120 are wearable devices, which are worn on the wrist of the subject to detect the physiological value of the subject. When the subject falls off the physiological detection devices 110, 120, the detectors 116, 126 send an abnormal notification and broadcast to the main control device 200 through the detection processors 111, 121, and contact the nursing staff in real time to understand the condition of the subject. Near Field Communication Tags (NFC Tags) 117 and 127 are disposed on one side of the physiological detection devices 110 and 120 to provide data corresponding to the detected subjects. In practice, the near field communication tags (NFC Tag) 117 and 127 can also be two-dimensional barcodes (Quick Response Code), which is not limited by this embodiment. When the physiological detection devices 110, 120 are separated from the subject, the near-field communication tags (NFC Tag) 117, 127 are used by the nursing staff to query the corresponding detected subjects of the physiological detection devices 110, 120, so as to avoid wearing or installing physiological devices. When the detection devices 110 and 120 confuse the subjects corresponding to the detection, resulting in errors in the detection of physiological values.

In this embodiment, the main control device 200 further includes a physiological data evaluation unit 240 and a warning device 230 . Physiological data evaluation unit 240 is used to compare physiological values C1 and C2, such as heart rate, blood pressure or body temperature, whether they fall within a reference value interval, so as to determine whether data processor 210 generates an alarm driving signal D to drive the alarm device 230. The reference value range is the range of physiological values that the human body should have under normal conditions. For example, the body temperature should be between 36 and 37.5 degrees, or the systolic blood pressure should be less than 120mmHg and the diastolic blood pressure should be less than 80mmHg. When the received physiological value exceeds the normal value range, the warning device 230 will send out a warning notification, for example, the luminous warning device will flash red light, or the buzzer will make a sound, so as to remind the medical staff to carry out necessary treatment in real time, so that the patient can be alerted and treated in real time care needs and improve the safety of medical care.

The following takes the application of the system of the present invention in a medical care center as an example to further illustrate the broadcasting of the measurement command signal A generated by the main control device 200 and the physiological data signals C1-C7 generated by the physiological detection devices 110-170 in the Bluetooth low power mesh network. path of. Please refer to FIG. 2 , which is a schematic diagram of the application of the system of the present invention to a medical care center. FIG. 2 is an application of the embodiment of FIG. 1 , to illustrate the flow of physiological data signal transmission of the physiological monitoring system of the present invention.

The medical care center shown in FIG. 2 includes a plurality of physiological detection devices 110-150. In actual situations, the physiological detection devices 110-150 can be fixedly installed on the hospital beds 1-5 due to the different conditions of each patient, or installed on a mobile wheelchair and worn on the patient through a wearable device, such as physiological detection Apparatus 160,170. Then, as mentioned above, in order to comply with the regulations on network transmission power in medical places, the effective transmission distance of the low-power Bluetooth mesh network used in this system is also limited. Therefore, if the main control device and the physiological detection device are too far apart, for example The main control device set in the nursing station and the multiple physiological detection devices set on the hospital bed or worn by the patient are scattered on different floors, so necessary broadcast signals may be missed. Therefore, the system further includes a plurality of fixed-end Bluetooth low-power transmission devices 310-330, which are arranged between the main control device and the plurality of physiological detection devices for relaying the received broadcast signals.

When the medical personnel want to measure the physiological value of the patient, the medical personnel use the main control device 200 at the nursing station to generate and broadcast the measurement command signal A to the outside. The measurement signal A is sent out in a broadcast manner, rather than being transmitted to a specific object. Therefore, all physiological detection devices and fixed-end Bluetooth low-power transmission devices within the effective network transmission range can receive the measurement command signal A broadcast by the main control device 200 . For example, the physiological detection device 160 in FIG. 2 is located within the effective network transmission range of the main control device 200 , so the measurement command signal A can be directly received from the main control device 200 . In addition, devices within the effective network transmission range of the main control device 200 also include a fixed-end Bluetooth low-power transmission device 330, so the fixed-end Bluetooth low-power transmission device 330 also directly receives the measurement command signal A from the main control device 200 and transmits it to the outside world. broadcast. Similarly, devices within the effective network transmission range of the fixed-end Bluetooth low-power transmission device 330, such as the fixed-end low-power Bluetooth transmission devices 310 and 320 and the physiological detection device 170, similarly receive data from the fixed-end Bluetooth low-power transmission device. After the broadcast at 330 , the measurement command signal A is broadcast to the outside. Then, the physiological detection devices 110, 120, 130, 140, and 150 located within the effective network transmission range of the fixed-end Bluetooth low-power transmission devices 310 and 320 respectively receive the measurement commands through the fixed-end Bluetooth low-power transmission devices 310 and 320 Signal A.

Similarly, the physiological data signals C1-C7 generated by the physiological detection devices 110-170 are respectively broadcast to the outside by the physiological detection devices 110-170. These broadcasts will be respectively received by the fixed-end Bluetooth low power transmission devices 310 - 330 located within the effective network transmission distance of each physiological detection device, and then broadcast to the outside world before being received by the main control device 200 .

It can be seen from the above description that this system mainly uses low-power Bluetooth combined with mesh network distribution to transmit signals in the form of broadcast. Bluetooth low power has the characteristics of low power consumption, low cost and high speed, while the mesh network completes the signal transmission and Receive purpose. Signal transmission in this way will not be limited to a specific distance and range, while taking into account the needs of low-power transmission in medical places.

In addition, the physiological monitoring system of the present invention provides the mechanism of sending voice information and responding to the testee's command input, so that the testee can decide whether to accept the test after assessing his own physiological condition, and the process of automatic measurement of the system takes into account Detection security.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the scope of the claims of the present invention. Therefore, all other equivalent changes or modifications that do not deviate from the spirit disclosed in the present invention should be included in this disclosure. inventions within the scope of patent protection.
