A system and method for pressurizing bags of physiological fluids include a control valve for providing deflation of a bladder that compresses the bags. The toggle portion of the control valve is movable between a first and second position respectively for inflation and deflation of the bladder. When the toggle portion is in the first position, the control valve connects a source of pressurized air to the bladder, and when the toggle portion is in the second position, the control valve allows the bladder to exhaust directly to the atmosphere through an outlet port in the valve. The size of the outlet port is so large that it creates only very little resistance to the discharged air.

A rolling element chain according to claim 1, wherein the at least one flexible element comprises two flexible strip elements extending in the longitudinal direction L and located at the lateral edge sections R of the supporting band. 3. A rolling element chain according to claim 2, wherein the at least one flexible element comprises: two spar elements forming the strip elements and running in the longitudinal direction L; and a plurality of sprocket elements extending laterally and interconnecting the two spar elements. 4. A rolling element chain according to claim 1, wherein: the at least one flexible element defines a longitudinally extending plane; and the retaining elements project above and/or below the plane defined by the flexible element. 5. A rolling element chain according to claim 1, wherein the retaining elements assigned to two longitudinally-adjacent rolling elements are arranged either all before or all after said two rolling elements. 6. A rolling element chain according to claim 5, wherein the retaining elements assigned to all of the rolling elements are arranged either all before or all after the respective rolling elements. 7. A rolling element chain according to claim 1, wherein, for two longitudinally-adjacent rolling elements, the at least one retaining element assigned to one of said two adjacent rolling elements is arranged longitudinally before said one rolling element and the at least one retaining element assigned to the other of said two adjacent rolling element is arranged longitudinally after said other rolling element. 8. A rolling element chain according to claim 7, wherein, for two longitudinally-adjacent rolling elements, either all retaining elements assigned to said two adjacent rolling elements are arranged longitudinally between said two adjacent rolling elements, or no retaining element assigned to either of said two adjacent rolling elements is arranged between said two adjacent rolling elements. 9. A rolling element chain according to claim 7, wherein the at least one retaining element assigned to said one rolling element and the at least one retaining element assigned to said other rolling element are longitudinally separated from one another by means of a laterally-extending sprocket element. 10. A rolling element chain according to claim 9, wherein, for two longitudinally-adjacent rolling elements, either all retaining elements assigned to said two adjacent rolling elements are arranged longitudinally between said two adjacent rolling elements, or no retaining element assigned to either of said two adjacent rolling elements is arranged between said two adjacent rolling elements. 11. A rolling element chain according to claim 9, wherein the sprocket element comprises two partial sprocket elements, the at least one retaining element assigned to said one rolling element is assigned to one partial sprocket element, and the at least one retaining element assigned to said other rolling element is assigned to the other partial sprocket element. 12. A rolling element chain according to claim 11, wherein: the at least one flexible element comprises two flexible strip elements extending in the longitudinal direction L and located at the lateral edges of the supporting band; the recesses are bounded on each lo
