Description

  The present invention relates to a support device in the form of a sheet or mattress, which relates to a support device for establishing control of blood flow of a body part on the support device, and more particularly comprises a vertically movable support portion. The support portion has the shape of a pressure plate attached to a piston rod having a piston in the cylinder, and the hydraulic fluid is supplied to and discharged from the cylinder chamber so that the pressure plate is raised and lowered, respectively. It is configured.

  Attempts have been made to alleviate the associated pain in persons who are forced to sit or lie down because of disability, in order to prevent and treat floor rubs that are particularly likely to develop.

  The most common treatment method is to use a pad or support that can disperse body pressure against the support. For this, more or less viscous fillers are used.

  However, the effect is “passive” rather than actively acting on the body to promote blood circulation.

  Patent Document 1 discloses the operation of a support portion configured in the form of a support member that alternately rises and falls. According to this document, it is described that bedsores are alleviated by promoting blood flow while appropriately supporting the body.

  However, in the above-mentioned support device, since the support part is actually merely raised or lowered, the blood is compressed at the same time, and the blood flows to the immediate area where the support part is lowered, so that the blood flow is sufficiently controlled. I couldn't do it and it didn't work at a satisfactory level. Since blood flow becomes irregular and irregular, it is uncomfortable for individuals, particularly those who have already developed floor rubs, and cannot be said to contribute to alleviation of bed slip.

British Patent No. 1540336

  An object of the present invention is to provide a support device in which the above problems and drawbacks are improved.

  The support device of the present invention that achieves the above object is a support device for establishing control of blood flow in a body part located on the support device in the form of a sheet or a mattress, the support device being vertically movable support And a support device that includes a pressure plate attached to a piston rod having a piston in a cylinder, and the pressure plate is raised and lowered by supplying and discharging hydraulic fluid to and from the cylinder chamber, respectively. The support device (1) has a plurality of cylinders (4) interconnected (5) by hydraulic pressure, one of the pressure plates (3) descends (6), and the adjacent pressure As the plate (3) is raised (7), a predetermined amount of blood (9) in the body part (8) is lowered (6) from the region on the raised pressure plate (3) (6) Move to the area on the adjacent pressure plate (3) It is characterized in that.

  According to the support device of the present invention, a plurality of cylinders interconnected by hydraulic pressure are provided, and when one of the pressure plates descends and the adjacent pressure plate rises, a certain amount of blood rises on the pressure plate. From this area to the area on the adjacent lowered pressure plate, the object can be achieved.

  Control of blood flow from the support point where the support part rises to the adjacent support point where the support part descends at the same time without the blood flow of the body irregularly permeating or staying in a very simple manner. Can be done completely. This provides a “closed” blood circulation from the raised cylinder to the adjacent lowered cylinder.

  With the above configuration, a sufficiently natural blood flow is promoted, and a natural flow of blood in the body with respect to the heart is promoted. Such a blood flow makes the movement on the support device very comfortable for a person who effectively treats floor rubbing and has difficulty in ensuring the blood flow of the body.

  According to the invention according to claim 2, since the cooperating support portions are arranged close to each other, the blood does not receive any pressure, and therefore does not cause any pain, and blood flow between points. Is easily obtained.

  According to the third aspect of the present invention, the support device is constituted by an area having a large number of support portions, so that a completely uniform and rhythmic movement of the support portions can be obtained. Thus, a completely uniform blood flow in the body part on the support device is ensured.

  According to the fourth aspect of the invention, the control is executed by the valve capable of transporting the hydraulic fluid between the cylinders operated at a predetermined cycle, so that the operation with reliability and the appropriate control are performed. The

  According to the invention which concerns on Claim 5, each pressure plate can be easily attached to a piston rod with a snap-type grip.

  According to the invention which concerns on Claim 6, a movement of a pressure plate is attained by forming a recessed part in the lower part of the pressure plate fixed on the ball-shaped edge part of a piston rod, and the shape of a body is obtained. A fit is obtained.

  According to the seventh aspect of the present invention, by limiting the range of the concave portion so as to surround the ball-shaped portion on the piston rod, the pressure plate can be inclined to easily adapt to various body shapes.

  Finally, according to the eighth aspect of the present invention, when there is a place where a load such as a painful part or a wound part should not be applied to the body part, one or a plurality of pressure plates can be removed.

In the support apparatus which consists of embodiment of this invention, it is the schematic which shows a mode that two adjacent support parts move. In the support apparatus which consists of embodiment of this invention, it is the schematic which shows a mode that two adjacent support parts move. In the support apparatus which consists of embodiment of this invention, it is the schematic which shows a mode that two adjacent support parts move. It is a partial cross section figure which shows the pressure plate attached to the edge part of a piston rod. It is a top view which shows the support apparatus provided with the valve (it shows with an outline) which controls the flow of the hydraulic pressure to each cylinder.

  Embodiments and functions of example methods and supporting devices according to the invention are described as follows with reference to the drawings.

  As described above, an object of the present invention is to promote blood flow, and the object is achieved by the support device described by FIGS.

  The support device denoted by reference numeral 1 includes a plurality of cylinders 4 connected to a hydraulic circuit including a pipe 5 shown in FIG. Hydraulic pressure is applied to each cylinder 4 at the bottom of the piston, and all pistons are at the highest position as shown in FIG. 1 (however, only cylinder B is lowered in FIG. 1).

  As shown in FIG. 4, each piston is provided with a piston rod having a pressure plate 3 attached to the tip. The joint between the pressure plate 3 and the piston rod 11 is preferably composed of a snap-type connecting portion including a ball portion 12 attached to the uppermost end of the piston rod 11.

  Since the ball-shaped recess is formed on the lower side of the pressure plate 3 and the pressure plate 3 is formed of an elastic material, the wall portion of the recess is bent around the ball 12. As such, the pressure plate 3 can be tilted as shown at an angle 13 and can be removed as shown by the dotted line 14 in FIG. 5 if it is necessary to avoid the effects of pressure. This is done when the user has or is likely to have an ulcer.

  In this example, the pad or cover 2 extends over the pressure plate 3 in order to flatten the gap between the pressure plates 3.

  The cross section of the body part 8 shown in the drawing is the part of the body that is supported by the support device.

  In FIG. 1, the pressure plate of the cylinder B is lowered, while the other pressure plate 3 is at the highest position. Therefore, as shown by hatching, blood 9 sinks toward a point on the pressure plate that has been lowered.

  After an appropriate time has elapsed, the valve device shown in FIG. 5 is switched to raise the descending pressure plate 3 as indicated by arrow 7, and at the same time, adjacent cylinder A is indicated by arrow 6. Is lowered. By such a change, the blood 9 is moved from the region on the cylinder B to the adjacent region on the lowered cylinder A. In FIG. 3 showing this result, the blood 9 moves to the pressure plate 3 of the cylinder A and sinks, so that the position changes from the cylinder B to the cylinder A.

  FIG. 5 shows an example of the valve device with the cover 2 removed in order to show the circular pressure plate 3. For the purpose of illustrating the structure, the cylinders are arranged in a row, and the cylinder indicated by A is arranged in a row adjacent to the cylinder B on one side and the cylinder F on the other side. Thus, in the example shown in the figure, six cylinders are arranged in one area. Each of these zones has, for example, 42 cylinders and constitutes a support device with 252 movable pressure plates.

  The distribution valve 10 having an inlet and an outlet for each cylinder 4 carries in the hydraulic fluid under pressure into all the cylinders (for example, A) and also carries out the hydraulic fluid from all the adjacent cylinders (for example, B). This causes the adjacent pistons to act so that blood flows in a “closed” circuit and blood effectively flows between adjacent support points.

  For example, it is possible to use a dispersion valve 10 in which the valve member is rotated stepwise by a stepping motor equipped with a driving device, and the pump causes liquid to flow in and out through the outlet holes of the valve.

  From the above, the functions of the support device can be summarized as follows.

  The pressure plates 3 connected to the cylinder 4 are divided into the same number of sets, and one set of them is always lowered.

  For example, as shown in the B set of FIG. 1, when the lowering set is filled, the hydraulic fluid of the adjacent A set is moved to the B set. During this function, sets A and B are not connected to the other sets C, D, E, F via hydraulic pressure.

  When all the inflow / outflow functions are completed, the B set is connected to the C, D, E, and F sets and interconnected as shown in FIG. 3 to equalize the overall pressure and completely into the user's skeleton. The user sits or lies on the B, C, D, E, and F sets that have the appropriate shape.

  The overall process is controlled by a valve and a pump unit connected thereto.

  By using such a device, the frequency of movement of the cylinder and the frequency of blood flow associated therewith can be achieved at a desired level with a simple and reliable operating instrument.

  The most common treatment method is to use a pad or support that can disperse body pressure against the support. For this, more or less viscous fillers are used.

  However, the effect is “passive” rather than actively acting on the body to promote blood circulation.

Patent Documents 1 and 2 disclose a supporting device that adapts to the contour of a body that rests on a mattress and equalizes the pressure of the body part. The mattresses described therein include support elements interconnected by hydraulic pressure, and the pressure on one or more descending support elements (generated from the body on the mattress) is hydraulic fluid. Is moved to another support element which is raised by.

Patent Document 3 discloses a support device that alleviates the progression of pressure ulcers or pressure ulcers. This support device consists of a vertical support element array having a pressure plate attached to a piston rod in a cylinder. Each cylinder is preferably pneumatically controlled and receives drive means, in particular air, from a common source via an actuator or servo valve on each cylinder. Each cylinder is connected to electronic control means including a control system with a microprocessor, whereby the lowering / raising of the support element is determined individually.

Another support and massage device is disclosed in US Pat.

Patent Document 5 discloses the operation of a support portion configured in the form of a support member that alternately rises and falls. According to this document, it is described that bedsores are alleviated by promoting blood flow while appropriately supporting the body.

  However, in the above-mentioned support device, since the support part is actually merely raised or lowered, the blood is compressed at the same time, and the blood flows to the immediate area where the support part is lowered, so that the blood flow is sufficiently controlled. I couldn't do it and it didn't work at a satisfactory level. Since blood flow becomes irregular and irregular, it is uncomfortable for individuals, particularly those who have already developed floor rubs, and cannot be said to contribute to alleviation of bed slip.
