Twenty-four members of the hospital team and six from Frank Wood Funeralcare took turns on an exercise bike in the hospital corridor to raise funds.
They need £3,000 to buy the therapy and have already raised more than £1250. They have also received an offer of sponsorship for the dog from Digby's Pets & Aquatics of Skegness.
These pictures show just some of the staff who took part.
