Novel Mobile Medical Oxygen Generator
The main purpose of this invention is to present a device solving the common problems seen in the
oxygen generators, called oxygen concentrators, on the current market. Oxygen generators generate
medical oxygen for patients.
Some of the main problems in the oxygen generators used for medical purposes are listed as
• Noise
• Inability to work for a long time under steady conditions
• Not allowing the use of a long cannula
• Requires a constant controller, accompanying person or wafter
• Manual control requirement during the power outages
• Requires manual control for different needs
The present technology offers unique solutions to solve each problem. This mobile oxygen
generator has unique advantages compared to competitors in the market. The main competitors are
Philips Respironics EverFlo, SimplyGo Travel, Devilbiss, OxyGo Next, iGO2 and SeQual Eclipse.
Despite each of them having a few advantages, our technology is combining all of these advantages
in an improved manner. Also, the uniqueness of the system is the automatic control system. In the
automatic control system, the oxygen flow rate is controlled depending on the oxygen level of the user.
The view of the system is shown in Figure 1. The capacity of the system seen in Figure 1 is 7 L/min,
which is the higher than the competitors. The size of the system is a cabin size luggage.
The main outcome of this project is the prototype, which we have developed a fully functional oxygen generator that has a 7 L/min flow rate. Also, the device has a data acquisition unit to measure and track the patients’ SPO2 levels. Thus, it has been possible to track the patients’ current SPO2 situation. For the case of SPO2 level reduced under 90%, the alarm has been set to warn the patient and patient relatives. This feature will be provided great convenience in the follow-up of covid patients. On the other hand, the oxygen generators are used in all patients who need oxygen therapy, such as asthma, COPD, heart failure, etc. For this purpose, we have added a unique feature in the device, which is to drive the oxygen flow rate. This feature has managed the oxygen flowrate automatically according to the patient's SPO2 value. One of the significant problems in the oxygen concentrator is the power outages. We have integrated an oxygen cylinder. It provides to continue oxygen flow when if a power outage or problem happens in the device. The device should be classified according to its features, such as entry-level, mid-level and advance-level. Two or three feature levels can make more competitive the device. These levels should be determined according to the patient's needs. For example, the automatically controlled device is for patients who have limited mobility. So, they only need a reliable and silent device that have oxygen flow rate up to 5 L/min. Automatic-controller and datalogger will provide higher life quality for them and their relatives. For a patient who has mobility, a light and silent device is required up to 2.5 L/min. When the present system is converted to the 2.5 L/min of the capacity, the size of the device will reduce the half of the present form.
