Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary oxygen supply, and in particular to an integrated oxygen bag device with flow control and oxygen display functions. Background Art

[0002] Portable oxygen supply devices are widely used in clinical emergency care, transport and rescue, and outdoor oxygen supply in high-altitude environments. Existing oxygen supply devices often use oxygen bags with one-way valves or simple mechanical flow valves. A common form is an air storage bag with a simple air output interface, which is inflated with a high-pressure oxygen cylinder. While this structure meets basic oxygen supply needs to a certain extent, it has many limitations.

[0003] First, most existing oxygen bag devices can only perform rough flow adjustments via mechanical knobs, and cannot achieve precise digital flow control. Improper adjustment can easily lead to insufficient or excessive oxygen supply, posing a risk of use. Secondly, key parameters such as the remaining oxygen in the oxygen bag, oxygen concentration, and pressure inside the bag cannot be displayed in real time, making it impossible to effectively monitor the patient's oxygen supply status and prone to blind operation. In addition, existing portable oxygen supply equipment generally lacks data recording and remote monitoring functions, and cannot synchronize oxygen supply process data to nursing terminals or remote devices in real time, affecting medical information management and the complete archiving of nursing data.

[0004] In addition, the structural design of existing devices tends to be oriented towards a single scenario and lacks the ability to adapt to multiple scenarios. For example, the differences in oxygen supply demand in scenarios such as plateau environments, ambulance transportation, and home chronic disease management have not been fully considered. The device is inconvenient to carry and the operation is complicated, which affects the actual application effect.

[0005] Therefore, there is an urgent need for an integrated oxygen bag device with intelligent flow control, real-time oxygen status display, data storage and remote management functions, and portability and multi-scenario adaptability to solve the above problems in the existing technology.

Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0028] Figure 1This is a schematic diagram of an integrated oxygen bag device with flow control and oxygen display functions according to Example 1 of the present invention. DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, the present invention provides an integrated oxygen bag device with flow control and oxygen display functions. The overall structure is compact and suitable for oxygen supply needs in multiple scenarios such as medical first aid, home care, field emergency, and plateau hypoxia.

[0031] The device includes:

[0032] The oxygen bag body 1, used to store oxygen, is made of medical-grade flexible material and has a capacity range of 50L to 60L. A transparent observation window measuring 15cm x 10cm is located on the outside of the bag, below the inflation port 2. A pressure-sensitive color-changing film is integrated into the transparent window, changing color according to changes in internal bag pressure. This provides a passive indicator of remaining oxygen, allowing the user to intuitively determine oxygen capacity and bag inflation status.

[0033] The inflation interface 2 is located on the side of the oxygen bag body 1 and adopts a multi-stage composite structure, which is compatible with high-pressure oxygen cylinders and automatic air pumps. The inflation interface 2 has a built-in check valve and dust cover to prevent reverse leakage. An inflation status indicator is provided at the interface to display the current inflation mode and progress. An intelligent recognition module is integrated inside, which can automatically identify the gas source type based on the input gas source pressure, distinguish between high-pressure oxygen cylinders and low-pressure air pumps, and automatically stop inflation when overpressure is detected, ensuring the safety of the inflation process.

[0034] The control and display panel 3 is located on the outer panel of the housing 5 and serves as the core control and display module of the device. The panel integrates:

[0035] The flow control assembly includes a multi-position physical button and an electronically controlled valve. The electronically controlled valve is a solenoid-operated valve that supports flow adjustment from 1 to 10 L / min and features soft start and stop functions to prevent sudden changes in the output airflow. The flow control assembly is equipped with a gear memory function, which automatically restores the last setting upon next use. The system also integrates environmental adaptive control logic that dynamically adjusts the output flow rate based on the remaining capacity of the oxygen bag or the external air pressure to ensure continuous and safe oxygen supply.

[0036] Oxygen Display: Utilizing an OLED display, it provides real-time displays of oxygen concentration, bag pressure, remaining capacity, and current output flow rate, supporting historical trend curves and dynamic color prompts. The oxygen concentration sensor has a detection range of 21% to 95% and a sampling period of 0.5 to 1 second. The pressure sensor has a detection accuracy of ±2.5 Pa and a sampling period of 5 to 20 milliseconds.

[0037] Main control circuit board: Integrates electronic control logic, power management, data processing and communication units to realize the flow control, data acquisition, alarm management and wireless communication functions of the whole machine.

[0038] Sensor signal acquisition unit: receives signals from oxygen concentration sensor and pressure sensor to realize real-time data acquisition and processing.

[0039] Bluetooth communication module: used to synchronize monitoring data to mobile devices or remote monitoring systems in real time.

[0040] Alarm module: When the oxygen concentration, pressure or flow rate is abnormal, it will issue an audible and visual alarm and vibration prompt, push the alarm to the mobile terminal via Bluetooth, and record historical alarm data.

[0041] The oxygen inhalation port 4, located at the outlet of the oxygen bag body 1, delivers a steady flow of oxygen to the patient through the flow control assembly. It utilizes a tangle-resistant rotary joint and a multi-angle swing mechanism, supporting both 6mm and 8mm standard ports and adapting to both adult and pediatric settings. A plug-and-lock mechanism prevents disengagement and ensures a secure connection to the nasal cannula or mask.

[0042] Shell 5 is the entire portable control housing, serving as the structural support and load-bearing body of the device. Shell 5 houses a battery compartment. The power system uses a 2000mAh lithium battery, supporting 80 hours of battery life and 1.5-hour fast charging. It features a charge-while-use function, and supports battery replacement and external backup power. Shell 5 is made of medical-grade non-slip and waterproof material, weighing less than 2.5kg. It is equipped with a carrying handle and a detachable shoulder strap, allowing it to be carried by hand, on the shoulder, or on the wall, meeting the needs of portable oxygen supply in multiple scenarios.

[0043] Furthermore, the device achieves intelligent steady-state control of oxygen flow output through a main control circuit. The control display panel 3 monitors output flow changes in real time via a sensor. Combined with feedback from the oxygen inhalation interface 4, it dynamically adjusts the opening of the electronically controlled valve to achieve steady-state flow output, maintaining output flow fluctuations within ±0.3 L / min.

[0044] The device features an automatic power-on self-test routine, with the control display panel 3 performing sensor calibration, valve function testing, and battery charge assessment at each startup. The system supports switching between manual and automatic modes, with the latter intelligently adjusting oxygen flow based on the patient's respiratory characteristics and environmental factors.

[0045] The display interface of the control display panel 3 has a multi-level status prompt function, including real-time oxygen supply status, power warning, fault code prompt and remote query function. The mobile terminal can realize remote data viewing and management via Bluetooth.

[0046] The device has a built-in data storage unit that can record the usage data of the last 30 days and supports data export function, which is convenient for hospital management and personal health record analysis.

[0047] The overall structural design is suitable for various scenarios such as ambulance transportation, air transfer, mountaineering emergency and home chronic disease oxygen supply, and has good ergonomic operability and environmental adaptability.

[0048] Application Examples

[0049] Hospitals are equipped with the integrated oxygen bag device provided by this invention to meet the on-site emergency oxygen supply needs of various patients with sudden respiratory distress. The following are two typical clinical application scenarios:

[0050] Scenario 1: Medium-flow oxygen supply for patients with altitude sickness

[0051] The emergency department received a passenger returning from the plateau who had acute altitude sickness, accompanied by shortness of breath and a drop in blood oxygen saturation to 85%. The nurse placed the device at the patient's side and performed the following operations:

[0052] 1. Turn on the power switch of the control display panel 3. The system will automatically perform a power-on self-test and complete valve detection and sensor calibration.

[0053] 2. Connect the portable high-pressure oxygen cylinder through the charging port 2. The device automatically identifies the gas source type and starts charging, and stops automatically when it is full.

[0054] 3. Set the flow control component to 5 L / min oxygen supply position, connect the Φ8 mm oxygen mask, and supply oxygen to the patient through oxygen inhalation port 4;

[0055] 4. The control display panel 3 displays the oxygen concentration, output flow rate and remaining capacity in the bag in real time, and synchronizes the data to the mobile nursing terminal, allowing nursing staff to remotely monitor the patient's oxygen inhalation status;

[0056] 5. During the oxygen supply process, if the patient's position changes, the device will automatically adjust the electronically controlled valve according to the flow rate feedback signal to maintain stable output and control the flow fluctuation within ±0.3L / min;

[0057] 6. The entire oxygen supply process is automatically recorded, and the nursing staff exports 30 minutes of usage data via Bluetooth and files it in the pre-hospital emergency record for subsequent diagnosis and treatment.

[0058] Through application in this scenario, the device achieves rapid and accurate oxygen supply to patients with sudden dyspnea in plateau environments, effectively improving emergency response efficiency and oxygen supply safety.

[0059] Scenario 2: Low-flow, precise oxygen supply control for COPD patients

[0060] During an intra-hospital transfer of an elderly patient with chronic obstructive pulmonary disease (COPD), the patient needed to receive continuous low-flow oxygen, and the oxygen concentration had to be strictly controlled. The nurse used the device of the present invention, and the operation process was as follows:

[0061] 1. Start the control display panel 3 and complete system initialization;

[0062] 2. Set the oxygen flow rate to 1.5 L / min, connect a Φ6 mm nasal cannula for oxygen inhalation, select "Concentration Target Control Mode," and set the target oxygen concentration range to 28%;

[0063] 3. The device realizes closed-loop control through the built-in oxygen concentration sensor and the electronically controlled valve, maintaining the output concentration stable within the error range of ±1%;

[0064] 4. During the oxygen supply process, the oxygen concentration, bag pressure and flow rate are displayed in real time, and the Bluetooth module synchronizes the data to the nursing station terminal;

[0065] 5. Record oxygen therapy data during the entire transfer period and export data files as a basis for nursing quality traceability.

[0066] This scenario demonstrates the technical advantages of this device in terms of fine flow control and low-concentration oxygen supply. It is particularly suitable for the transport of patients with chronic diseases such as COPD and heart failure who require strictly controlled oxygen therapy dosage.

[0067] In summary, the integrated oxygen bag device of the present invention fully realizes the precise control and real-time monitoring of the oxygen supply flow rate through structural innovation and functional integration, and solves the problems of the existing oxygen bags that are unable to dynamically adjust the flow rate, the residual volume is not visible, and the use is inconvenient. The device adopts an integrated control display panel, which integrates the flow control, parameter display, main control logic, data management and communication functions, and improves the operational convenience and intelligence level. Through the portable design, it meets the application needs of multiple scenarios and has wide applicability for plateau oxygen supply, mobile rescue, emergency rescue and home chronic disease oxygen supply. The present invention has a reasonable structure, simple operation, comprehensive functions, and has good promotion value and industrialization prospects.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
