In view of “Covid-19” , Naval Dockyard, Mumbai has designed and developed its own handheld infrared (IR) based temperature sensor, through in-house resources, for undertaking screening of large number of personnel at the entry gates of the yard, to reduce the load on the security sentries at the gate.
The instrument has been manufactured under Rs. 1000/ -, which is fraction of the cost of the temperature guns in the market. The dockyard has the capability to scale up production of these if required towards which sourcing of the components is in progress.
Since the outbreak of coronavirus, the non-contact thermometers or temperature guns have become scarce in the market and are being sold at a very high cost. To overcome the scarcity the Naval Dockyard, has developed, this sensor with accuracy of 0.02 deg celsius. The non-contact thermometer has a, IR sensor and an LED display integrated with a microcontroller which runs on a 9 volts battery. This initiative has provided a tool for undertaking screening of large number of personnel at the entry gates, Commander Mehul Karnik said and added the temperature can be checked without touching a person.
Naval ships continue to remain mission deployed during COVID-19 crisis and the deployments are being planned without any port visit to the extent possible or with at least a gap of 14 days at sea from the last port visit prior return.
The 285 year old Naval Dockyard of Western Naval Command (WNC) has an average influx of around 20,000 personnel entering its premises every day. In view of Covid-19, initial screening of the personnel entering the dockyard was essential to prevent the spread of the virus within the yard and the Western Fleet. The most preliminary method to screen a probable patient is to check for body temperature by a non-contact means. Although there is a lock down across the country, the work of shipping building and research is going on and there is constant in and outflow of officers, sailors and civilians at Naval Dockyard.
In another development, the Naval Dockyard, Visakhapatnam has designed an innovative ‘Portable Multi-feed Oxygen Manifold (MOM)’ using a 6-way radial header fitted to a single cylinder. This would enable one oxygen bottle to supply six patients concurrently thus enabling critical care management to a larger number of Covid 19 patients with the existing limited resources. The entire set up was made operational by manufacturing a fine adjustment reducer and specific adapters of requisite dimensions for connecting the Oxygen cylinder and the portable MOM.
 A typical oxygen providing facility at hospitals comprises a cylinder feeding only one patient through a Venti-mask arrangement. During the ongoing pandemic, ventilator support is  required for about 5-8% of patients with symptoms and a large number of patients require oxygen support.
