Description

Technical Field

[0001] This utility model relates to the field of medical monitoring equipment technology, specifically a medical monitoring system based on Bluetooth and power line carrier communication. Background Technology

[0002] In the field of medical monitoring, existing monitors rely on wired connections to various sensors, such as electrode pads, which must be attached to the patient's body surface. However, this presents numerous problems in practical applications. Most patients using monitors are unconscious, delirious, or in a state of agitation. When a patient unconsciously turns over, the cables can easily pull on the electrode pads, causing them to detach from the patient. This not only affects the accuracy of the monitoring data but also causes discomfort to the patient. Patients in a state of agitation or delirium may pull on the electrode wires, potentially causing injury to themselves or medical staff. Excessive pulling can also damage the monitor, thus hindering the normal operation of medical monitoring, increasing the workload of medical staff, and posing potential risks to the patient.

[0019] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, this utility model proposes a medical monitoring system based on Bluetooth and power line communication, including N wireless monitors 1, a switch 2, a monitoring center server 4, a computer terminal 5, and a family member mobile terminal 6. The wireless monitors 1 are communicatively connected to the switch 2, the switch 2 is communicatively connected to the monitoring center server 4 via a local area network 3, and the monitoring center server 4 is communicatively connected to the computer terminal 5 and the family member mobile terminal 6. Patient monitoring data collected by the multiple wireless monitors 1 is transmitted to the monitoring center server via the switch and the local area network. The electrocardiogram (ECG) monitoring data of each patient is displayed on the computer terminal, and simultaneously, the monitoring center server transmits monitoring signals to the mobile terminal via a wireless network (e.g., 4G / 5G) for wireless monitoring.

[0021] like Figure 2 As shown, the wireless monitor 1 includes a communication processor 11, a Bluetooth communication chip 12, a power module 13, a monitor processor 14, a carrier communication module 15, a LoRa communication chip 16, a power cord interface 17, and a network communication interface 18. The communication processor 11 is communicatively connected to the Bluetooth communication chip 12, the power module 13, the monitor processor 14, the carrier communication module 15, the LoRa communication chip 16, and the power cord interface 17. The carrier communication module 15 is communicatively connected to the network communication interface 18. The power cord interface 17 is electrically connected to the power module 13 and the carrier communication module 15. The Bluetooth communication chip 12 is wirelessly connected to multiple patient-worn terminals 7. The power cord interface 17 is electrically connected in parallel to the remaining N-1 wireless monitors 1 in the same power line network; where N is a positive integer greater than 2.

[0022] like Figure 3 As shown, the patient-worn terminal 7 includes a microprocessor 71 and a battery module 72, a Bluetooth communication module 73, a temperature sensor 74, a pulse sensor 75, a blood pressure sensor 76, and a blood oxygen saturation sensor 77, all electrically connected to the microprocessor 71. The patient-worn terminal 7 is fixed to the patient's body, and the monitored vital signs data, such as temperature, pulse, blood pressure, and blood saturation, are wirelessly transmitted to the Bluetooth communication chip 12 of the wireless monitor 1 via the Bluetooth communication module 73.

[0023] The communication processor 11 of the wireless monitor 1 communicates with the monitor processor to receive sensor detection data, performing on-site monitoring and display functions in the existing monitor operating mode (because the monitor is existing technology). Figure 2The existing monitoring modules (such as display and buttons) are not shown; only the processor module is described. On the other hand, the collected monitoring data is transmitted to the switch via the network communication interface 18 in the form of power line carrier modulation through the carrier communication module 15. Other wireless monitors are also connected to the same power line network and send their monitoring data to the switch. Additionally, the monitoring data is wirelessly transmitted to other monitoring terminals via the LoRa communication chip 16.

[0024] The communication processor 11 and the monitor processor 14 are either ARM processors or DSP processors, and their models are not specifically limited.

[0025] Power module 13 is a low-voltage DC switching power supply used to convert AC mains voltage into voltage for the operation of the wireless monitor.

[0026] The carrier communication module 15 is model C7710. At the transmitting end, the data signal is first modulated onto a high-frequency carrier signal by a modulator, and then coupled to the power line for transmission via a coupler. At the receiving end, the carrier signal is extracted from the power line via a coupler, and then demodulated by a demodulator to restore the original data signal. It features an embedded automatic frequency identification circuit and intelligent multi-frequency automatic switching. When the main frequency is interfered with by noise, it can select an interference-free frequency that meets practical application standards and has a high transmission rate from 255 frequency points as the carrier frequency for data transmission, completing intelligent switching and effectively avoiding interference. Simultaneously, the chip also incorporates proprietary bpsk modulation technology with automatic modulation ratio adjustment, which can automatically adjust the data carrier modulation ratio according to the network environment, improving data transmission speed without reducing communication reliability.

[0027] Network communication interface 18 is an Ethernet port or a 485 communication interface, used to send power line carrier modulated signals to the switch.

[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
