The UV machine that cleans every corner of hospitals from coronavirus

The fight against Covid-19 is also being fought these days to the millimeter in every corner of hospital centers for cleaning teams. The coronavirus has shown to have a high transmission capacity and easy attachment to all kinds of materials in an invisible way. Its resistance complicates the disinfection work of the rooms in the midst of a health crisis.

One of the most innovative techniques in this particular battle against the virus is the germicidal ultraviolet irradiation lamps (UVGI) . With this technology, both hospital rooms and operating rooms are free of the bug after its passage in a short period of time.

“They are very effective because they destroy both DNA and RNA, where the genetic programming of viruses and bacteria is located. A total destruction in a short time that allows almost immediate access to the rooms”, highlights the doctor from the Clínica Universidad de Navarra, Francisco Guillén Grima, whose centers in Madrid and Pamplona apply this pioneering work technique.

It is a relatively new technology in Spain. With traditional space sterilization techniques, such as hydrogen peroxide and gas or steam bottles, patients must wait between one and three hours to gain access to the room . While ASEPT-2x UV equipment allows entry in just over 10 minutes after the last patient leaves.

“We received them just two years ago. The first time we used them was because an infectious patient had undergone surgery, but the operating room was urgently needed for a heart transplant. In these cases, they notify you when there is a possible donation and must act immediately. We put the two towers in and in 20 minutes the operating room was operational, “adds Guillén Grima, who was also one of the 70 scientists who signed the manifesto sent to Pedro Sánchez in March requesting the confinement of the population.

Manufactured by the Canadian firm Sanuvox , the equipment has a height of just over one and a half meters. Weighing just 45 kilos, its transport is carried out easily with its guide wheels throughout the hospital premises.

The only drawback that these devices can have are the shadow areas that the UV lamp generates when it operates. To counteract this handicap, the technical staff places the machine at various points in the rooms, thus avoiding any nooks and crannies with viruses.

“One of the teams consists of two towers that work simultaneously and each lamp is activated for five minutes. Now with the coronavirus issue we have risen to six minutes to ensure disinfection as a total safety margin. With the coronavirus crisis we have also we rented four more towers because we were not enough, “adds the specialist.
