Ordered that the order is reversed insofar as appealed from, on the law, with costs, and the motion for summary judgment dismissing the complaint is granted.
"To prove a prima facie case of negligence, a plaintiff must demonstrate the existence of a duty, a breach of that duty, and that the breach of such duty was a proximate cause of his or her injuries" ( Coral v State of New York, 29 AD3d 851, 851; see Alvino v Lin, 300 AD2d 421). The defendant established its entitlement to judgment as a matter of law by demonstrating that its alleged delay in providing a wheelchair to the plaintiffs' decedent was not a proximate cause of her injuries ( see generally Bank v Lincoln Shore Owners, 229 AD2d 370). In opposition, the plaintiffs failed to raise a triable issue of fact. The plaintiffs' contention that the decedent fell because she was weakened from the alleged long wait for a wheelchair is speculative ( see Hardman v Long Is. Urological Assoc., 253 AD2d 849, 850).
