OxyJet

The OxyJet is a medical device designed to provide patients with high-flow oxygen while in their beds. With the capacity to supply up to 60 liters of oxygen, this device has been approved by the Directorate General of Drug Administration for limited use under the supervision of the Department of Biomedical Engineering's teachers and students at Bangladesh University of Engineering and Technology.

Working principle

The device works by supplying natural oxygen from the surrounding air and combining it with standard cylinder oxygen, resulting in a total oxygen supply of around 60 liters. This process does not require any electricity. In comparison, a standard hospital bed typically includes a 15-liter oxygen flow-meter that delivers oxygen to the patient via a mask. The Oxyjet device utilizes a unique design, employing two flow-meters instead of the standard single unit. This configuration is capable of supplying an impressive 50-60 liters of oxygen, although the typical flow rate is around 15 liters. The Oxyjet operates by creating a vacuum, enabling surrounding air to enter the device. To administer oxygen, the Oxyjet utilizes a non-vented CPAP mask, which forms a tight seal over the patient's mouth and cannot be readily vented. Additionally, the device features a peep valve, which effectively regulates the oxygen pressure for optimal patient comfort and safety. Doctors believe that individuals experiencing respiratory issues can effectively combat oxygen deficiencies through the utilization of OxyJet technology. Furthermore, this innovative device enables healthcare professionals to provide critical oxygen support in remote areas and during transportation. While a standard hospital bed can typically provide a maximum of 15 liters of oxygen per patient, cases of severe respiratory distress often require higher levels of oxygen administration. In such instances, a high-flow nasal cannula (HFNO) or intensive care unit (ICU) may be necessary. However, in special situations like epidemics, there is a shortage of ICU or necessary equipment. The Oxyjet device has the potential to play a significant role in addressing the aforementioned challenges. With a projected price point of 20-25 thousand taka per unit, this device offers a cost-effective and user-friendly solution that can be readily utilized in emergency scenarios such as ambulances. Furthermore, the Oxyjet has been shown to significantly enhance patient blood oxygen levels (i.e., oxygen saturation), increasing levels by an average of 11.2% within just one hour of treatment. Patients with Covid-19 require supplemental oxygen, which is usually administered through HFNO or Continuous Positive Airway Pressure (CPAP) procedures. In this, Oxygenate gives oxygen through CPAP system.

Authorization and use

Deputy Director of the Directorate General of Drug Administration of the Government of Bangladesh, Salahuddin said initially 200 devices would be produced. Moreover, post-marketing surveillance of OxyJet would be warranted, where every patient's data would be kept to see if it was benefiting the patient, or if it had any side effects or risks.
