SUBSTANCE: group of inventions refers to medicine. An adapter assembly comprising a collector and a valve assembly. The valve assembly comprises a seat and a valve body having a round base and a wall. The wall projects from a back side so that to form a domed shape having an end that is slotted; the wall forms opposite sealing edges in the slot. The seat has an upper ring surface and a lower ring surface. The upper surface is coupled with a front side of the base whereas the lower surface is coupled with the back side. At least one of the upper and lower surfaces form an elevated sector. After assembled completely, the valve body is placed across a collector passage; the slot provides a selectively opened passage. A force applied by the elevated sector curves the base and displaced the sealing edges into the coupling.

EFFECT: group of inventions enables improving the optimality of the prolonged multiple valve sealing.
