Description

Technical Field

[0001] This application belongs to the field of smart medical technology, and more specifically, relates to an intelligent oxygen inhalation system that supports central monitoring and regulation. Background Technology

[0002] Oxygen is essential for human life. Oxygen deficiency can lead to respiratory dysfunction, and in severe cases, damage to vital organs and tissues such as the heart and brain, even endangering life. Blood oxygen saturation (SpO2) is the percentage of oxyhemoglobin in the blood that can bind oxygen, representing the oxygen content in the blood and is an important parameter for assessing the function of the human respiratory and circulatory systems. Clinically, patients with respiratory failure, chronic obstructive pulmonary disease, or other cardiopulmonary dysfunction, as well as critically ill patients and surgical patients, require continuous oxygen therapy to increase the partial pressure of oxygen in the blood, thereby improving their condition. Monitoring blood oxygen saturation values ​​is crucial for indicating the oxygen content in the blood. Therefore, controlling and monitoring the oxygen flow rate, as well as ensuring the comfort of the inhaled oxygen temperature and humidity, is extremely important.

[0003] Currently, hospitals generally use liquid oxygen for patient oxygen therapy. This liquid oxygen undergoes depressurization and vaporization, and the flow rate is regulated using a float-type flow meter at the patient's bedside. If the oxygen flow rate needs adjustment, medical staff must manually adjust the float-type flow meter at the patient's bedside. Similarly, if monitoring the patient's vital signs during oxygen therapy is required, medical staff must go to the patient's bedside to measure and record these signs. This results in low work efficiency for medical staff. Utility Model Content

[0030] Figure 1 This application provides an intelligent oxygen inhalation system that supports central monitoring and adjustment. Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] like Figure 1 The image shows an intelligent oxygen therapy system supporting central monitoring provided in an embodiment of this application. It includes a central monitoring module located at the monitoring end and a local oxygen therapy control module located at the user end. The local oxygen therapy control module includes: a microprocessor unit, a wireless communication unit, a flow control unit, a heating and humidification unit, a humidification bottle, a vital signs measurement unit, a display screen, a flow adjustment button, and a temperature adjustment button.

[0033] In the local oxygen control module, the microprocessor unit acts as the central processing unit, controlling its operation. It connects to the wireless communication unit, flow control unit, heating and humidification unit, vital sign measurement unit, display screen, flow adjustment button, and temperature adjustment button via multiple signal ports. It performs functions such as data storage, calculation, transmission, and protocol conversion.

[0034] In the local oxygen control module, the wireless communication unit is a peripheral unit of the microprocessor unit, enabling connection and communication between the local oxygen control module and the central monitoring module. Wireless communication can be achieved using technologies such as Bluetooth, Wi-Fi, and mobile communication networks.

[0035] In the local oxygen control module, the flow control unit includes a flow sensor, a stepper motor, and an oxygen valve.

[0036] The microprocessor unit digitizes the flow rate setpoint and converts it into the rotation amount of the stepper motor. This rotation amount is then sent to the stepper motor, which rotates accordingly. The rotation of the stepper motor causes the oxygen valve to open and close. The oxygen valve is located in the oxygen pipe, thus achieving digital regulation of the oxygen flow rate. A flow sensor located downstream of the oxygen valve collects the oxygen flow rate and returns it to the microprocessor unit.

[0037] In this embodiment, the flow control unit has a range of 0SLM to 30SLM and supports a working pressure range of 10MPa.

[0038] The oxygen then flows through the oxygen output pipe into the humidification bottle, where it is humidified and heated by the humidifying liquid. The heated and humidified oxygen then flows out of the humidification bottle and is inhaled by the patient.

[0039] In this embodiment, the heating and humidifying unit controls the temperature of the humidification bottle, thereby increasing the temperature and humidity of the flowing oxygen by increasing the temperature of the humidification bottle.

[0040] In this embodiment, the heating and humidifying unit includes a water bath unit and a temperature sensor; the humidification bottle is immersed in the water bath unit.

[0041] The temperature sensor is a digital temperature sensor located in the water bath unit. It collects the water bath temperature of the water bath unit. The microprocessor unit obtains the water bath temperature in real time through the temperature sensor. If the temperature is lower than the set lower limit, the heating component in the water bath unit is activated to heat the water. If the temperature is higher than the set upper limit, the heating is stopped, thereby realizing the temperature regulation of the humidification liquid in the humidification bottle.

[0042] In this embodiment, the vital signs measurement module is a non-invasive pulse oximeter. It collects oxygen saturation and pulse data from the patient's finger using a non-invasive pulse oximeter method, and returns these measurements to the microprocessor module for subsequent display. This provides medical personnel with an accurate and real-time understanding of the patient's oxygen saturation, enabling precise adjustment of oxygen flow and preventing them from blindly adjusting the oxygen flow based on experience.

[0043] The vital signs measurement module can also include other measuring instruments, such as electrocardiogram (ECG) meters and blood glucose meters.

[0044] In this embodiment, the display screen can display various parameters, including real-time flow rate, flow rate setpoint, water bath temperature, temperature setpoint, vital signs information, and oxygen inhalation time.

[0045] In this embodiment, the flow rate adjustment button can adjust the flow rate setting of the flow controller. The temperature adjustment button can adjust the temperature setting of the water bath unit.

[0046] The flow rate and temperature adjustment buttons can be adjusted using a rotary knob, button, or touchscreen.

[0047] In this embodiment, the central monitoring module is installed at the nurse station and communicates with the aforementioned microprocessor module via a wireless communication unit.

[0048] This central monitoring module can connect to multiple local oxygen control modules, enabling the monitoring and adjustment of multiple patients receiving oxygen simultaneously. Once connected to the central monitoring module, local oxygen control modules can be remotely controlled via the central monitoring module. This includes adjusting flow and temperature setpoints, displaying basic patient information such as bed number and name, as well as real-time parameters such as flow rate, oxygen administration time, water bath temperature, blood oxygen saturation, and pulse rate. This achieves unified remote monitoring and control of the oxygen control device.
