A method and a platelet concentrate preservation device for platelet concentrate storage. A method includes at least partially saturating platelet concentrate xenon, and storing the platelet concentrate at less than 15 C in a generally horizontal position. A device can be used to store blood, blood products, or combinations thereof that may or may not be under pressure. The device includes a chamber having a cavity. The chamber includes first and second chamber parts that form the cavity when releasably connected together. The cavity is designed to receive at least one bag that contains the blood, blood products, or combinations thereof. The device also includes a high-strength casing and includes a chamber cavity. The high-strength casing includes first and second casing parts that form the chamber cavity when releasably connected together. The chamber cavity is designed to receive the chamber.

This disclosure describes a combined autologous biologic and cold therapy treatment for treating various skin injuries. The treatment may include applying autologous blood components, including but not limited to platelet rich plasma, to a skin injury in a manner that influences the healing process. A tray assembly for freezing autologous blood components includes a tray body and a plurality of compartments formed in the tray body. Each of the plurality of compartments is configured to receive an individual dose of an autologous blood component.

A hanging device (100A) used in an additive solution transfer method includes an upper hanging section (106) and a support mechanism (lower hanging section (108)). The upper hanging section (106) is used to hang a medical fluid bag (54) upside down. The support mechanism (lower hanging section (108)) supports a primary bag (50) or a transfer line (55) in a predetermined state such that, when a red blood cell preservation liquid (M) is transferred from the medical fluid bag (54) to the primary bag (50) using the height difference between the primary bag (50) and the medical fluid bag (54), air from the medical fluid bag (54) is stopped in the middle of the transfer line (55).
