[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0015] Please refer to Figures 1 to 5, the present invention provides a technical solution: a patient monitor that uses environmental sensors to exclude environmental interference, including a monitor body 1, a display screen 2 is installed on the surface of the monitor body 1, a main control board 5 is installed inside the monitor body 1, a vital sign sensing module 6 is installed on the main control board 5, and the vital sign sensing module 6 is used to regularly sample and transmit data from the human body to provide accurate vital sign monitoring data. An environmental sensing module 7 is installed on the main control board 5, a data processing module 8 is installed on the main control board 5, a switching power supply board 9 and an integrated parameter board 10 are installed inside the monitor body 1 through brackets. The switching power supply board 9 is one of the important components in the monitor. It is responsible for converting the input AC power into a stable DC power supply to provide the required electrical energy for each circuit inside the monitor. The integrated parameter board 10 integrates the processing and display functions of multiple monitoring parameters. It usually includes various sensor interfaces, signal processing circuits, and display driver circuits, etc. The design of the integrated parameter board 10 enables the monitor to simultaneously monitor multiple vital signs and display the monitoring results in real time. A printer compartment 12 is installed on the side of the monitor body 1, and the vital sign data of the patient, such as heart rate, blood pressure, blood oxygen saturation, etc., can be printed in real time through the printer compartment 12. The printed data can be used as the patient's medical record for subsequent analysis and diagnosis. An alarm lamp board 13 is installed on the monitor body 1 so that medical staff can quickly notice the alarm information. A battery compartment 14 is installed on the back of the monitor body 1 to provide electrical energy through the battery compartment 14. The battery compartment 14 can be opened and closed. A battery connector is equipped inside the battery compartment 14 for electrical connection with the battery. When the monitor body 1 has no power, the battery can be replaced to ensure its normal use.

[0016] It should be noted that the data processing module 8 is divided into four steps: data reception and integration, environmental impact analysis, data correction algorithm, and interference exclusion. When processing data, it first receives the data streams from the vital sign sensors and environmental sensors, analyzes the impact of environmental factors on the vital sign monitoring data according to the data of the environmental sensors, and then, according to the preset algorithms and models, corrects and adjusts the body temperature data in a high-temperature environment. Finally, through precise data processing and correction, the interference of environmental factors on the vital sign monitoring results is excluded.

[0017] Furthermore, the vital sign sensing module 6 is composed of a heart rate sensor, a blood oxygen sensor, and a body temperature sensor. It should be noted that the heart rate sensor monitors the heart rate changes of the patient in real time, and a photosensitive element is used to measure the blood flow changes on the skin, thereby deriving the heart rate data. When light penetrates the skin, a part of it is absorbed by the skin, and the other part is reflected back to the sensor. The pulsation of the heart causes changes in the blood volume in the skin, and this change affects the amount of light absorption. The photosensitive element on the sensor receives the reflected light and converts it into an electrical signal. After further processing, the heart rate data is obtained. The blood oxygen saturation of the patient is measured by the blood oxygen sensor. The absorption amount of the emitted light in the blood is measured through the transmitter and receiver built in the optical sensor, and then the value of the blood oxygen saturation is measured. The body temperature change of the patient is monitored by the body temperature sensor. The body temperature sensor converts the body temperature change into voltage, resistance, displacement, or optical signal through different mechanisms, and then presents it as a specific temperature value through circuit processing and display devices, thereby achieving the effect of monitoring the body temperature.

[0018] Furthermore, the environmental sensing module 7 is composed of a temperature sensor and a humidity sensor. Most temperature sensors use thermocouples or thermistor temperature elements to measure temperature by utilizing the electromotive force difference generated by two different metals when the temperature changes. A film made of a humidity-sensitive material is covered on the humidity sensor. When water vapor in the air adsorbs on the humidity-sensitive film, the resistivity and resistance value of the element both change. By using this characteristic, the environmental humidity can be measured. The temperature sensor and the humidity sensor work synchronously with the vital sign sensor to monitor the environmental conditions in real time and transmit the data to the data processing module 8.

[0019] Furthermore, feet 4 are installed at the bottom of the monitor body 1, and anti-slip pads are bonded to the bottom surface of the feet 4. The feet 4 can provide multiple contact points, effectively increasing the stability of the monitor placement, and improving its anti-slip effect through the anti-slip pads, so that the monitor generates friction, avoiding the phenomenon of tipping even if the monitor is accidentally touched during use, thereby improving the stability.

[0020] Furthermore, a handle 3 is rotatably connected to the top of the monitor body 1. Through the handle 3, it is convenient for the staff to hold and carry, and the handle 3 can be rotated to fit the top surface of the monitor body 1 to avoid blocking.

[0021] Further, a parameter interface 11 is provided on the side wall of the monitor body 1, and an external interface 15 is provided on the back of the monitor body 1. The parameter interface 11 and the external interface 15 are used to connect lead wires. The parameter interface 11 and the external interface 15 are connected to the lead wires. One end of the lead wire is connected to the patient, and the other end is inserted into the external interface 15 of the monitor. Once the lead wires are connected to the monitor, they will start transmitting the patient's physiological parameter signals (such as electrocardiogram signals, blood pressure signals, etc.). These signals enter the monitor through the interface and are further processed and analyzed by the data processing module 8.

[0022] Further, the display screen 2 is electrically connected to the data processing module 8. Data transmission can be achieved through the electrical connection between the display screen 2 and the data processing module 8. It should be noted that the data processing module 8 includes specially designed software or algorithms for data correction and analysis of environmental impacts. These software can be dynamically adjusted according to the actual monitoring conditions to ensure continuous and effective elimination of environmental interference, and the module values after data processing will be displayed on the display screen 2 for the monitoring personnel to view and monitor.

[0023] Usage method and advantages of the present invention: When the patient monitor that uses an environmental sensor to eliminate environmental interference is working, the working process is as follows: As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 shown, when using this monitor, first connect the monitor and the patient's body through the lead wire to receive the patient's electrocardiogram signal. Turn on the monitor through the control switch. Collect the patient's heart rate, blood oxygen saturation and body temperature data through the heart rate sensor, blood oxygen sensor and body temperature sensor inside the physical sign sensing module 6, and monitor the temperature and humidity changes around the monitored patient through the temperature sensor and humidity sensor in the environmental sensing module 7. The collected data is transmitted to the data processing module 8 via wireless Bluetooth. The data processing module 8 receives and integrates the data streams monitored by the physical sign sensing module and the environmental sensing module 7, analyzes the data of the temperature change in a high-temperature environment or the humidity fluctuation under high-humidity conditions detected by the environmental sensing module 7. According to the data of the environmental sensing module 7, the data processing module 8 uses a preset correction algorithm to adjust and correct the physical sign data, effectively eliminating the interference of these environmental factors on the monitoring results, improving the accuracy of the monitoring data, ensuring the reliability of the monitor under various environmental conditions, and thus enhancing the patient's monitoring safety and medical quality.
