Abstract

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.

First claim

What is claimed is:

1. A method, comprising:
harvesting a blood sample from a patient;
separating an autologous blood component from the blood sample;
injecting an individual dose of the autologous blood component into each of a plurality of compartments of a tray assembly, wherein the tray assembly includes a tray body that establishes the plurality of compartments, a rack removably connected to the tray body, and a plurality of handles removably connected to the rack, wherein one handle of the plurality of handles extends into each of the plurality of compartments;
positioning the tray assembly within a freezer to freeze the individual doses of the autologous blood component;
removing a first dose of the individual doses from the tray assembly, wherein removing the first dose of the individual doses includes removing a first handle of the plurality of handles from the rack; and
applying the first dose to a skin injury in frozen form,
wherein applying the first dose to the skin injury initially provides cold therapy to the skin injury, and as the first dose melts, the autologous blood component is distributed over the skin injury to promote healing.

2. The method as recited in claim 1 , wherein the one handle of the plurality of handles includes a collar that completely covers each of the plurality of compartments that contains the first dose when the one handle is connected to the tray assembly.
