PUNE: The civic body has launched an “oxygen concentrator library”, under which Covid-19 patients would get the gadget free of cost at their homes or in hospitals. “The citizens in need of this facility can approach the Pune Municipal Corporation (PMC) and get the units at their homes,” said Vikram Kumar, the Pune municipal commissioner. Those in need of this service can contact the PMC on 9881190696. According to a statement issued by the PMC office, the prescription and the advice of using oxygen concentrator should be given to the patient by a doctor. After that, the patient can reach out to the PMC and seek the unit. The residents in home isolation or taking rest post-Covid treatment in home would benefit from this initiative. The units would be given to patients for different time spans like seven, 15 or 30 days, depending on the advice of the doctor and the requirement of the person concerned. Patients would have to provide documents like prescription of registered doctors, Aadhaar card and address proof like electricity bill, details about how many days the concentrator would be used, affidavit about the possession of the unit and a copy of Covid positive report.
