Abstract
The present disclosure relates to improved collapsible blood containers comprising reinforced silicone for use in Oxygen Reduction Disposable kits (ORDKit), devices and methods. The improved collapsible blood containers and methods for the collection of blood and blood components provide for improved burst, tear, and puncture resistance.
Claims14
An oxygen depletion device 10 for depleting oxygen from blood prior to anaerobic storage comprising:
- an outer receptacle 101 substantially impermeable to oxygen;
- an inner collapsible blood container 102 comprising one or more chambers that are permeable to oxygen;
- and
- an oxygen sorbent 103 situated within said outer receptacle 101.
A silicone membrane 700 comprising:
- a silicone membrane 113 having an area 702 and an average thickness 703 of less than 100×10−6 M (μm), and a feature 701 on at least one side of said silicone membrane 113 comprising silicone having an average length 713 of between 100 μm and 10000 μm perpendicular to an average length 714 of between 20 μm and 5000 μm.
