Abstract: A cuff seal for a spacesuit includes a rigid base member and a flexible seal member disposed within the base member. The seal member comprises a hinge portion and a contact portion extending therefrom. The contact portion is capable of flexing about the hinge portion and can be placed in pressure sealing contact with a blood supplied tissue, such as a wrist area, due to a gas pressure within the spacesuit.

Abstract: A mechanical counter pressure glove includes an elastic supportive material and a plurality of pre-pressurized bladders in the supportive material. At least one of the bladders is configured to match a configuration of a palm of a hand. The bladders may also be configured to match other parts of the hand, such as the dorsum and fingers. Each of the bladders is pre-pressurized to match a tissue pressure in the user's hand prior to the glove being worn. Thereby, the bladders are self contained and omit the need for a constant available supply of gas pressure from an external source.
