Description

A DEVICE FOR STIMULATING BLOOD CIRCULATION

The present invention relates to a device for stimulating blood circulation in a users leg and in particular to a device for use by people travelling in a confined space, such as in an aeroplane cabin, to help prevent deep vein thrombosis.

Deep vein thrombosis (DVT) is a blood clot (a thrombus) that develops in a deep vein, usually in a calf or thigh muscle. This usually occurs when a vein is damaged or when the flow of blood slows down or stops. Deep vein thrombosis can cause pain in the leg and can lead to complications if it breaks off and travels in the bloodstream to the lungs (called a pulmonary embolism).

It is well known that prolonged immobility, such as during long distance travel, can increase the likelihood of DVT. This is as a direct result of a reduction in blood flow around the lower limbs. In recent years particular concern has risen in relation to long distance airplane travel, in which passengers are typically immobile for relatively long periods of time in sometimes very cramped conditions. In the light of this a number of devices have been proposed for use by passengers travelling in an airplane to exercise the passengers legs thereby stimulating blood flow and reducing the likelihood of DVT.

Devices such as that described above have a disadvantage in that they require modification of an otherwise conventional seat assembly, are relatively bulky and heavy (particular disadvantage in relation to airplanes, and can require maintenance). a

For example GB 2377651 discloses an exercise device for feet and legs that comprises a frame that may replace the foot rest under a seat in a vehicle such as an airplane. The frame pivots at a point under the seat to allow the foot rest to be pressed down, resistance being provided by springs or hydraulic devices, which return the foot: ..

rest to a rest position. The foot rest may also pivot on the frame, allowing the user to rotate the ankle. The exercise is intended to stimulate blood flow in the lower limbs S..

while seated.

It is an object of the present invention to provide a device for stimulating blood circulation in a user's legs, which obviates or mitigates the above disadvantages.

According to the present invention there is provided a device for stimulating blood circulation in a users leg, the device comprising a base, a single foot pedal hinged to the base, and biasing means acting between the foot pedal and the base to provide resistance to pivoting movement of the pedal about the hinge.

The inventor has recognised that sufficient stimulation of blood flow can be achieved from a relatively simple and lightweight device. In particular, the inventor has recognised that there is no requirement for a device which can be used to exercise both legs at once. Rather, a user can simply exercise one leg for a period of time and then the other. Indeed this is likely to be more acceptable to a passenger travelling for instance in a plane for example allowing one leg to be exercised' whilst the other leg can be relaxed in a comfortable position (bearing in mind, that the object is simply to stimulate blood flow in the leg and not to over exert the passenger). This latter fact may be particularly important in relation to elderly or otherwise infirm passengers.

Provision of a device with only a single foot pedal also reduces the size and weight of the device. This again is a particular advantage when the device is used by a passenger. For instance, storage capacity and weight allowance for articles carried on a airplane is very limited. Devices according to the present invention could be stored in conventional locker space provided on airplanes for passenger use. For example, a plane could carry a small number of such devices which could be distributed amongst passengers and then redistributed as necessary. Indeed, the device according to the present invention can be made small enough and light enough to be carried onboard * a by a user as part of the users hand luggage. With this in mind, devices according to the present invention are preferably made of lightweight plastics materials.

The small size of the device according to present invention also minimizes the..

likelihood of a device being used by one passenger encroaching on the personal space of a neighbouring passenger or otherwise inconveniencing another neighbouring a a... a * *

passenger. ** In preferred embodiments of the invention the biasing means is pre-loaded when the foot pedal is in a rest position. For instance, where the biasing means is a compression spring, the travel of the foot pedal may be limited so that in a rest position (i.e. without force supplied by a users foot) the spring is slightly compressed.

The pedal and base may be substantially planar and have substantially the same outer profile so that the size of the device is minimized.

In preferred embodiments the hinges located adjacent an end edge of the pedal and base but in alterative embodiments the hinge could be located in the region of a midpoint of the pedal and base.

Although in preferred embodiments of the invention the base is a plate like structure, the base may alternatively comprise a frame.

In preferred embodiments of the invention the biasing means comprises one or more coil springs. For instance, the biasing means may comprise two compression springs located adjacent one another.

Although preferred and advantageous features of the present invention would be

apparent from the following description.

A specific embodiment of the present invention will now be described, by way of example only, with reference to the accompanying drawings, in which: Figure 1 is an exploded perspective view of an embodiment of the present invention; and Figures 2a and 2b are side views of the embodiment shown in figure 1 in a closed and open state. S...

S S S. *

As shown by figures 1, 2a and 2b, the illustrated device according to the present invention comprises a substantially planar and rectangularly shaped base plate 2, a substantially planar and rectangularly shaped foot pedal 4 and two coil springs 6.

The base plate 2 and pedal 4 are similarly sized and shaped and dimensioned to accommodate a users foot. The pedal is pivotably attached at a first end to the base plate by a hinge 8. The pedal and base plate are also coupled at a second end (opposite to the first end) via the two springs 8 which act to bias the pedal 4 and base 2 apart.

The pedal 4 can be pressed downwards by a foot 8 against the biasing force of the coil springs (as shown in figure 2a), the second end of the pedal 4 and the base plate 2 being moved towards one another, compressing the springs 6, while the first end of the base plate 2 and the pedal 4 remain a fixed distance apart.

When no force is applied to the pedal 4, the two springs 6 push the second end of the pedal 4 away from the base plate 2 (as shown in Figure 2b), the first end of the pedal 4 and the base plate 2 again pivoting about the hinge 8 to return to the rest position.

A user by repeatedly pushing the pedal 4 against the resistance of the springs 6 will increase their blood circulation and therefore reduce the likelihood of DVT.

The pedal 4 is sized and shaped so as to be suitable to provide a platform for a foot 8.

Adjacent to the proximal short side of the pedal 4a and on the upper surface of the pedal, there is provided a heel stop 22. The heel stop 22 juts out creating a surface 22a against which a heel of a foot can press and so help maintain the position of the foot *. a

during use.

On the upper surface 28 of the pedal 4 there are two non-slip surfaces 24a, 24b that reduce the risk of a user's foot 8 slipping, causing injury to the user or someone in the..

immediately vicinity. The first non-slip surface 24a is disposed adjacent to the heel stop 22. The second non-slip surface is separated from the first non-slip surface and is positioned so that it is located where the ball of a range of feet 8 of different sizes are located when using the device.

On the underside of base plate 2, there is also a third non-slip surface 25. The third non-slip surface 25 is provided to increase the friction between the device and the floor and thereby helps stop the base plate 2 from moving when in use.

The hinge is formed by three lugs 12a, 12b, 12c, two integrally formed with the pedal and one integrally formed with the base plate 2, and a hinge pin 16 that passes through a hole in each of the lugs. The two pedal lugs 12b, 12c extend downwards, each with centrally positioned holes lOb, lOc and are separated by a distance X. The base plate lug 1 2a projects upwardly from the base plate 2 with a centrally positioned hole lOa. Caps 18 and 20 are fitted over respective ends of the hinge pin to hold it in position.

The two springs 8 are mounted to the base plate on two substantially cylindrical bosses 26. The lowermost coil of each spring is hooked over a boss 26 and is thereby prevented from moving horizontally. Similarly, opposite ends of each spring are mounted on bosses provided on the underside of the pedal 4. The bosses also define spring steps limiting the travel of the pedal.

Various materials could be used to fabricate the pedal 4 and base 6. Preferably, the components are fabricated from a lightweight plastics material, for example by compression moulding. * e * .* S.. * **

it will be appreciated that other embodiments of the invention a single compression spring could be used in place of the two compression springs illustrated. Similarly, other forms of biasing means could be used, including but not limited to resilient mass (such as a sponge block) or a bellevill washer or other spring mechanism such as a leaf spring or the like. S S. *SSS

S S S S. *

The currently preferred biasing means is however two stainless-steel compression springs with internal spring stops provided by bosses 26, each spring having a length of 25mm when subject to a load of 57N, a length of 40mm when subject to a load of 38N, a length of 50mm when subject to a load of 26N, a length of 60mm when subject to a load of I 7N and a length of 80mm when subject to no force. Further, the springs have a diameter of 35.5 mm and are made from wire having a diameter of 2.03mm. These springs are currently preferred as they enable users of a range of muscular strengths and body weights to the use the device to increase their blood circulation.

It is also preferable that the springs are slightly pre-loaded both to hold them in position and also to provide a desirable force characteristic when the device is in use.

For instance, with the springs mentioned in the paragraph above, it is preferable to provide stops limiting the pivoting movement of the foot pedal to ensure that the springs cannot extend to greater than about 60mm, such that the springs always have a minimum of 20mm compression. This is conveniently achieved by the appropriate configuration of one or more of the lugs 12a, 12b and 12c. For instance in relation to Fig 2b it can be seen that the travel of the foot pedal under the force of the spring 6 is limited by contact of the bottom rearmost corner of lug 12b (and similarly 12c) with the base plate. It is a simple matter to configure and dimension one or more of the lugs 12a-12c to provide an appropriate limiting stop to give any desired spring preload.

It will also be appreciated that different forms of hinge could be used to couple the pedal to the base for instance, with a moulded plastic component the hinge could be a plastic web type hinge. Other possible modifications to the embodiment of the invention illustrated and described above will be readily apparent to the appropriately skilled person. 0* * * * * a. S... * a a... a... S. *
