Can I suggest that you apply to be the Essential Care Giver, it will allow you to continue visiting even if there is a Covid outbreak in the care home. You will have to follow the same testing regime as the staff, I go to the home once a week for a PCR test as well as have an LFT test before each visit. I am allowed to go any time I want and go in mums room, her other three named visitors see her in a visiting room for just half an hour at a time. In reality, ECGs are treated as if they are staff.
However, should your husband test positive for Covid, you will not be allowed to visit until after a period of isolation, my mum tested positive last week so I’m not visiting at the moment.
