donation agreement(If the donation is monetary in nature (as the first part of your context suggests) it would be called a DONATION AGREEMENT. If such agreement pertains to donating equipment (as the second part of your context suggests) then it could be a USED EQUIPMENT DONATION AGREEMENT. "Whenever a donation is made, a written agreement[2] should be entered into between the donor and the medical institution specifying the type, quantity, quality, value and designated purpose for the use of the donation as well as the rights and obligations of the two parties." More specifically these are called "designated donation agreements." proz.com Alexander Demidov)
