[0047] Clinical application examples

[0048]

[0049] Intelligently adjust the oxygen output flow rate to reduce ineffective oxygen consumption. During oxygen therapy, when the patient's blood oxygen saturation exceeds the set target value by 2%, the oxygen concentrator can automatically reduce the output flow rate to reduce waste; when the patient's blood oxygen saturation is lower than the set target value by 2%, the system automatically increases the flow rate. This not only ensures the safety of oxygen inhalation, but also greatly reduces oxygen waste.

[0050] Clinical application examples

[0051] The doctor ordered a flow rate of 3L / min, with a target blood oxygen saturation of 96%. When the blood oxygen value reached 98% during oxygen therapy, the system automatically reduced the flow rate, maintaining a minimum of 1L / min, saving 66.67% of oxygen consumption during the period.

[0052] Precise flow control ensures the safety of oxygen therapy for special patients.

[0053] The oxygen concentrator has a metering accuracy of 0.2L / min, which is far higher than the national industry standard of 1L / min. The flow error is small, and oxygen therapy is safer.

[0054] The minimum setting value is 0.5L / min, which effectively meets the clinical needs of 0.5L / min low-flow oxygen inhalation for newborns, and fills the technical defect that the float-type oxygen inhaler cannot accurately measure the low flow of 0.5L / min.

[0055] Full safety monitoring makes care easier.

[0056] During the entire oxygen therapy process, the patient's blood oxygen level and pulse rate changes are dynamically monitored, and alarms are issued for safety hazards such as abnormal blood oxygen values, abnormal pulse rate, and broken oxygen tubes, ensuring the safety of oxygen therapy throughout the entire process.

[0057] At the same time, the oxygen concentrator is automatically shut down when oxygen therapy is finished, and the oxygen absorption data is automatically saved and remotely transmitted to the monitoring terminal, and can be output and printed as needed, easily realizing information management and greatly reducing the workload of nurses.

[0058] The beneficial effects of the present invention are:

[0059] It can provide patients with dynamic blood oxygen saturation values ​​and pulse rates in real time, making it easier for medical staff to accurately judge the patient's hypoxia level and reduce the probability of giving incorrect medical advice.

[0060] Based on the set target blood oxygen saturation, the oxygen output flow is automatically controlled to improve the safety and effectiveness of oxygen therapy.

[0061] According to the dynamic changes of the patient's blood oxygen value, the oxygen concentrator can automatically adjust the oxygen output flow rate within the doctor's prescribed flow range, so that the patient's blood oxygen saturation is stably controlled within the target range.

[0062] During the treatment, the oxygen concentrator can set the target value of blood oxygen saturation and the upper and lower limits of oxygen flow. The oxygen concentrator will automatically adjust the oxygen output flow according to the patient's blood oxygen concentration, so that the patient's blood oxygen concentration saturation reaches a close to the target setting value, so as to monitor the patient's status and keep track of the patient's status at any time. During oxygen therapy, the patient should achieve and stably maintain the treatment goal.

[0063] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention.
