Abstract
Abstract Apparatus including a member for attachment to a part of the body which member is capable of activating the part of the body cyclically. The member may comprise one or more double flexible sleeves alternatively or additionally it may comprise a mechanical linkage connected to a part of the body which includes linkage deforming means to cyclically deform the linkage and move the part of the body.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
Apparatus comprising at least one flexible member adapted to fit on part of the body, said flexible member comprising at least one cell, the apparatus further comprising a mechanical linkage adapted to be attached to a part of the body and linkage deforming means which are capable of deforming the linkage to oscillate said part of the body about a body joint, the linkage deforming means comprising at least one further inflatable cell with said one cell of the flexible member and said further cell of the deforming means being connected to means for cyclically inflating and deflating both said one cell and said further cell.
Claim 2
Dependent Claim
106 words
Apparatus comprising at least one flexible member adapted to fit on part of the body, said flexible member comprising at least one cell, the apparatus further comprising a mechanical linkage adapted to be attached to a part of the body and linkage deforming means which are capable of deforming the linkage to oscillate said part of the body about a body joint, the linkage deforming means comprising at least one further inflatable cell with said one cell of the flexible member and said further cell of the deforming means being connected to means for cyclically inflating and deflating both said one cell and said further cell.
Claim 3
Dependent Claim
71 words
Apparatus according to claim 1, wherein there are provided a plurality of flexible members, each comprising a single cell which cells are adapted to fit on or around a part of the body adjacent one another and which are connected together in series each connection providing a restricted passage such that the cells may be inflated and deflated in succession to impart a cyclic force to said part of the body.
Claim 4
Dependent Claim
13 words
Apparatus according to claim 1, wherein said flexible member comprises an annular tube.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 1, wherein said flexible member is formed from a flexible plastics material.
Claim 6
Dependent Claim
28 words
Apparatus according to claim 1, wherein said means for cyclically inflating and deflating the cells comprise a pump adapted to provide alternately gas under pressure and an exhaust.
Claim 7
Dependent Claim
10 words
Apparatus according to claim 5, wherein said gas is air.
Claim 8
Dependent Claim
34 words
Apparatus according to claim 5, wherein said means for cyclically inflating and deflating the cells also comprise pressure control means by which the pressure of the gas in a pressure stroke may be controlled.
