Definitions
- the present invention relates to a support device in the form of a seat or a mattress for the establishment of a controlled flow of blood in a body part resting on the support device, in which vertically movable supports are disposed, said supports being in the form of pressure plates mounted on a piston rod with a piston in a cylinder, to which hydraulic liquid may be sup- plied and be discharged from the cylinder chamber to raise and lower the pressure plate, respectively.
- the most common treatment consists of the use of pads or supports which are capable of distributing the pressure of the body against the support. This may be done by means of more or less viscous fillers.
- GB 1 540 336 discloses activation in the support in the form of support members which are alternately raised and lowered. This is said to promote the flow of blood and thereby counteract decubitus, while providing a con- venient support of the body.
- it has not operated satisfactorily, as the flow of blood is not controlled to a sufficient degree, but solely takes place in that a support is moved up or down, whereby blood is pressed together and flows to the nearest area where a support is lowered. This will mean that the flow of blood becomes arbitrary and irregular and thereby uncomfortable for the individual, in particular those who have already developed decubitus, just as it does not contribute to remedying this.
- a support device comprising a plurality of cylinders which are interconnected hydraulically such that when one of the pressure plates is lowered, an adjacent pressure plate is raised, whereby a given amount of blood in the body part is moved from the area above the pressure plate which is raised, and to the area above the adjacent pressure plate which is lowered.
- the flow of blood in the body is not an arbitrary seepage or accumulation of blood, but a completely controlled flow from a support point where the support is raised, and to an adjacent support point whose support is simultaneously lowered, so as to create a "closed" circulation of blood from the cylinder which is raised, to an adjacent cylinder which is lowered.
- the support device is configured in the form of zones with many supports, a completely even rhythmic movement of the supports is achieved, thereby ensuring a completely even flow of blood in the parts of the body which rest on the support device.
- control is provided by means of a valve which is capable of conveying hydraulic liquid to and from the activated cylinders with a given cycle, an operationally reliable and expedient control is achieved.
- the individual pressure plates are mounted on the piston rod by means of a snap-like grip, it is ensured that the pressure plate may be mounted easily.
- a depression is provided on the lower side of the pressure plate, on which a ball-shaped end part on the piston rod may be secured, it is ensured that the pressure plate may be moved and thereby conform to the shape of the body.
- the extent of the depression is limited and thereby the encirclement of the ball-shaped part on the piston rod, it is ensured that the pressure plate may tilt and thereby easily conform to the various body shapes.
- one or more pressure plates may be removed, e.g. below sores or other injuries on the body which may not be loaded.
- fig. 4 shows how a pressure plate, shown in section, is mounted on the end of a piston rod
- fig. 5 shows a support device seen from above with a valve, shown in outline, for the control of the hydraulic flows to the individual cylinders.
- the support device which is designated 1 , comprises a plurality of cylinders 4, which are connected with a hydraulic circuit comprising pipes 5, as indicated in fig. 5. Hydraulic pressure is applied to each cylinder 4 below the piston, so that all the pistons are in the highest position, such as e.g. in fig. 1 , in which, however, one cylinder B is lowered.
- Each piston is provided with a piston rod which carries a pressure plate 3 at the top, as shown in fig. 4.
- the joint between the pressure plate 3 and the piston rod 11 preferably comprises a snap-like coupling comprising a ball part 12, which is disposed on the uppermost end of the piston rod 11.
- a ball recess is provided on the lower side of the pressure plate 3, and since the pressure plate 3 is made of a resilient material, the wall in the recess will be able to snap around the ball 12. In this manner, the pressure plate 3 will be able to tilt, as indicated by the angle 13, just as it may be removed, e.g. as shown in dashed line 14 in fig. 5, in those cases where it might be necessary to avoid pressure impacts. This might be in the event that the user has or is likely to incur ulceration and the like.
- a pad or a cover 2 extends above the pressure plates 3 in order to even out gaps between the pressure plates 3.
- the drawing shows a section through a body part 8, which is the part of the body which is supported by the support device.
- a valve device as shown in fig. 5, will be switched to raise the lowered plate 3, as indicated by the arrow 7, and at the same time the adjacent cylinder A is lowered, as shown by the arrow 6.
- This change will cause the blood 9 to be driven from the area above cylinder B to the adjacent area above the lowered cylinder A.
- Fig. 5 shows an example of a valve device without a cover 2 in order to show the pressure plates 3 in the form of circles.
- the cylinders are arranged in a row, and such that cylinders marked A are arranged in a straight line at the side of cylinders B at the one side and cylinders F at the other side, thus six cylinders in a zone in the example shown.
- Each of these zones has e.g. 42 cylinders, which together form a support device having 252 movable pressure plates.
- a distributor valve 10 having an inlet into and an outlet from the individual cylinders 4 ensures that hydraulic liquid under pressure is conveyed to all the cylinders, e.g. marked A, at the same time as hydraulic liquid is conveyed away from all the adjacent cylinders, e.g. marked B. This provides the desired effective flow of blood between adjacent support points, as the blood flows in a "closed" circuit, while adjacent pistons operate.
- a distributor valve 10 in which the valve member is rotated stepwise by a stepping motor having a drive device, and where a pump distributes liquid out and in via outlet openings on the valve.
- the pressure plates 3 with associated cylinders 4 are divided into sets with an equal number in each set, where one of the sets is always lowered.
- set B will be connected with sets C, D, E and F, so that, as shown in fig. 3, the user now sits or lies on sets B, C, D, E and F, which are interconnected and thereby give a total pressure equalization and simultaneously assume a shape which is completely adapted to the user's anatomy.
- This entire process is controlled by a valve and an associated pump unit.
- any desired frequency of the movements of the cylinders and thereby of the flow of blood may be achieved by means of a simple and very operationally reliable appliance.
