Definitions

  • the invention relates to a pump comprising a wall which forms a closed-off fluid volume and which can be moved by means of a first external force in the direction of a volume reduction and by means of a second force, after a preceding volume reduction, in the direction of a volume increase, and with an inlet valve which communicates with an inlet port and with an outlet valve in an outlet line in the fluid volume.
  • the invention relates, furthermore, to a use of a pump of this type.
  • Pumps of this type are known, for example, as hose pumps, in which the fluid is expressed from a fluid-filled hose by means of pressure rollers pressing the hose together and moved in a longitudinal direction of the hose. As a result of the movement of the roller, the upstream end of the hose is filled with fluid again when this end is connected to a fluid supply.
  • the propulsive force for moving the rollers is generated by a motor which may be designed, for example, as an electric or hydraulic motor. Pumps of this type are used for conveying a volume in the pressure direction.
  • Another kind of pump of the type initially mentioned is diaphragm pumps, in which the fluid volume is reduced by the diaphragm and moved back and forth by means of a connecting rod and is subsequently increased again.
  • the connecting rod thus transmits both the first force for the volume reduction and the second force for the volume increase.
  • the object on which the invention is based is, therefore, to design a pump of the type initially mentioned such that it can be implemented in a small space.
  • a pump of the type initially mentioned is characterized in that it is designed as a vacuum pump, the volume of which can be reduced by means of the external first force against an elastically deformable material, the return force of which forms, after the termination of the external force action, the second force acting counter to the generated vacuum.
  • the working stroke by which the fluid, in particular air, is sucked away from a closed-off volume is brought about by the return force of the elastically deformable material. Previous deformation for reducing the volume of the fluid material takes place by means of a first force acting externally.
  • the pump according to the invention thus makes it possible to have a very uncomplicated and small-volume design, by means of which a low to medium vacuum can be generated.
  • the wall has two rigid walls lying opposite one another, the elastically deformable material being arranged in the interspace formed by the walls.
  • the elastically deformable material may be formed by a sealing insert running around the edge and delimiting the fluid volume.
  • the wall is designed flexibly, the elastically deformable material bearing, preferably over a large area, against the flexible wall, In this case, a high return force sufficient for many applications can be generated by means of a relatively thin material layer.
  • the elastic material may be an open-pored foam which is arranged within the fluid volume and which exerts the return force after a volume reduction has been carried out.
  • the fluid which is preferably air, accordingly flows through the foam.
  • the generation of the return force does not take up any additional space at all, since the fluid volume itself is utilized for this purpose.
  • An alternative elastic material which is capable of throughflow and which can be used for the invention is a wide-mesh knitted fabric.
  • the pump according to the invention is implemented in a simple way if the elastic material is surrounded on all sides by the flexible wall. It is also possible, however, for the wall to be partially of rigid design and for a part of the wall such as is required for the volume reduction to be made flexible.
  • the pump according to the invention can preferably be produced with a preferred large-area extent and with a thickness which is small, as compared with this, and can therefore in many instances be integrated into the structure of a device without difficulty.
  • the fluid volume with a flexible wall may be arranged between two large-area pressure elements.
  • the valves may be arranged on the corresponding narrow sides of the flexible wall, but are preferably also arranged in recesses of one of the pressure elements or of both pressure elements, with the result that flexing actions of the flexible wall are reduced.
  • the pump according to the invention can advantageously be integrated in the force flux of a system in which forces arise which are utilized to exert one of the two forces.
  • the pump according to the invention is suitable particularly as a vacuum pump.
  • the pump constitutes part of a prosthesis for a lower extremity.
  • the force occurring due to body weight when a patient treads on the ground is utilized as the first force.
  • the pump may be employed, in particular, for the vacuum assistance of a suction well of the prosthesis, in particular for evacuating the interspace between a liner and the prosthesis shank.
  • a preferred place of use for the pump according to the invention is an artificial foot which makes it possible particularly effectively to have the large-area design of the pump perpendicularly to the force flux occurring during load caused by the body weight.
  • FIG. 1 shows a diagrammatic illustration of a pump in the initial state according to a first embodiment
  • FIG. 2 shows the pump according to FIG. 1 in the compressed state
  • FIG. 3 shows a pump in an initial state according to a second embodiment
  • FIG. 4 shows a pump in a third embodiment which is integrated into an artificial foot
  • FIG. 5 shows an arrangement of an elastically deformable material consisting of two layers with profilings which point toward one another and in the nonloaded state form a fluid space;
  • FIG. 6 shows the arrangement according to FIG. 5 in a loaded state in which the compressed material of the layer completely fills the fluid space
  • FIG. 7 shows an embodiment of a pump according to the invention with two rigid plates lying opposite one another and with an insert running around at the edge and consisting of an elastically deformable material, in the nonloaded state;
  • FIG. 8 shows the arrangement according to FIG. 7 in the loaded state.
  • the pump illustrated in FIG. 1 has a closed fluid volume 1 which is filled virtually completely with an elastic material in the form of an open-pored elastic foam 2 .
  • the foam 2 has a substantially large-area extent with a small width. It is surrounded on all sides by a flexible wall 3 which thus has four narrow sides and two large-area sides with large dimensioning, as compared with these.
  • Two large-area pressure elements 4 , 5 bear against the large-area sides.
  • the flexible wall 3 has on opposite narrow sides a tubular or hose-shaped feed 6 and a tubular or hose-shaped outlet 7 . Both the feed 6 and the outlet 7 are provided in each case with a nonreturn valve 8 , 9 .
  • the pressure elements 4 , 5 are moved relatively toward one another, as illustrated in FIG. 2 .
  • the fluid volume 1 together with the foam 2 contained in it is thereby pressed together, with the result that fluid, preferably air, escapes via the nonreturn valve 9 and the outlet 7 .
  • the elastic return force of the foam 2 ensures that the fluid volume 1 returns to the initial state of FIG. 1 , fluid being sucked into the fluid volume 1 via the inlet 6 and the nonreturn valve 8 .
  • the pressure plate 5 ′ is provided with recesses 10 in which the nonreturn valves 8 , 9 are arranged, The flexing actions of the flexible wall 3 in the region of the nonreturn valves 8 , 9 are thereby markedly reduced.
  • FIG. 4 shows an example of the use of a pump of the type described in FIGS. 1 to 3 .
  • the pump is in this case integrated into an artificial foot 11 , the functional set-up of which is connected to a lower-leg tube 12 of a lower-leg prosthesis.
  • the functional part of the artificial foot consists of an S-shaped spring insert 13 , the free ends of which form an upper junction limb 14 and a lower sole limb 15 . Between these is located an essentially horizontal intermediate piece 16 which is connected to the junction limb 14 and to the sole limb 15 in each case by means of a curved transition piece 17 , 18 such that the essentially horizontal intermediate piece 16 can spring in relation to the sole limb 15 of the insert 13 under the action of a weight.
  • the distance between the intermediate piece 16 and the sole limb 15 is reduced.
  • This distance reduction is utilized for the pump employed according to the invention, in that the intermediate piece 16 is connected to a pressure element 5 ′′.
  • the pressure element 5 ′′ of large area per se, is adapted in its form to the form of the intermediate piece 16 and of the curved transition 17 , in order to make it easier to position the pressure element 5 ′′.
  • the fluid volume 1 filled by the foam 2 is located, within the flexible wall 3 surrounding the foam 2 on all sides, between the pressure element 5 ′′ and the sole limb 15 functioning here as a counterpressure element 4 .
  • connection 6 , 7 is indicated merely diagrammatically, said connection extending through a recess 10 of the pressure element 5 ′′ and being connectable, for example as an inlet 6 , via a hose line to the interspace between an amputation stump and a liner surrounding the amputation stump, in order to evacuate this interspace.
  • the functioning of the pump inserted into the foot 11 corresponds fully to the functioning explained with reference to FIGS. 1 to 3 .
  • the load on the artificial foot 11 due to the body weight acts as a pressure force for the pressure element 5 ′′, with the result that the intermediate piece 16 is pressed downward in the direction of the sole limb 15 and thus presses together the fluid volume 1 and the foam 2 . Air thereby escapes from the fluid volume 1 .
  • the foam 2 causes the pump to return to the initial position illustrated in FIG. 4 .
  • an artificial foot 11 is suitable for integrating the pump according to FIG. 4 , because it is easily possible to have a large-area design of the fluid volume 1 and of the foam 2 perpendicularly to the (vertical) force flux because the anatomy of the foot 11 likewise tends to extend over a large area. It is nevertheless also possible, of course, to arrange a corresponding pump in other prosthesis parts which execute a relative movement with respect to one another, for example in a knee joint.
  • FIGS. 5 and 6 show an exemplary embodiment in which the elastically deformable material is formed by two layers 21 , 22 which point toward one another in each case with a profiled surface 23 , 24 .
  • the profiled surfaces are in this case formed by projections 25 , the width of which is smaller than a recess 26 between the projections 25 .
  • the tips 25 of the layer 21 accordingly project into the recesses 26 of the layer 22 , and vice versa, thus giving rise to the spaces which form the fluid space 1 and which are not filled by the elastically deformable material.
  • the layers 21 , 22 may be formed from a plastic having stability such that the layers 21 , 22 at the same time form the wall 3 .
  • the layers 21 , 22 may also cooperate with pressure plates 4 , 5 , such as are illustrated in the embodiments according to FIGS. 1 to 3 .
  • the fluid space is delimited by two rigid walls 31 , 32 parallel to one another and by an insert 33 which runs around and connects the edges of the rigid walls 31 , 32 sealingly to one another and which consists of an elastically deformable material.
  • the insert 33 is in this case a channel-like profile consisting of a stable fluidtight material which is connected, fluidtight, to the walls 31 , 32 by adhesive bonding or the like.
  • FIGS. 5 to 8 can be employed in the same way as the exemplary embodiments according to FIGS. 1 to 3 , that is to say, in particular, also in an artificial foot or the like,
  • the pumps according to the invention may be used, in particular, in prosthesis parts also for other purposes, for example as a hydraulic pump for the control of dynamic functions, for example for the control of hydraulic damping cylinders or for the movement of structural elements of the prosthesis, for example from an uncoupled to a coupled state, in order to carry out dynamic adaption to the situation of use.
