Abstract

The present invention relates to an intermittent compression stocking comprising at least one inflatable cell and having a portion which adheres to a further portion of the stocking to secure the stocking in position.

Description

INTERMITTENT COMPRESSION STOCKING
This invention relates to intermittent compression stockings and, in particular, to an intermittent compression stocking which is wrapped around a portion of a limb of a bedridden patient.
Such stockings may be used for a variety of therapeutic purposes. For instance, the intermittent compression action of such stockings stimulates the large sinusoidal veins of a patient's legs, duplicating the effect of normal walking. Consequently, normal veinal circulation may be assisted. Fibrinolysis is also aided by the intermittent compression action so that the likelihood of blood clotting may be reduced. In addition, diverticulitis (DVT) may be prevented or managed by the use of such intermittent compression stockings.
Hitherto, intermittent compression stockings have comprised a single inflatable cell or a pad comprised of a number of cells which are sequentially inflated in use. Generally, such stockings are formed as a pad which can be rolled around the leg of the patient, being secured in position by a buckle, strap or a Velcro (TM) strap. There are, however, disadvantages associated with the use of buckles and straps since precise fitting of the stocking is rarely possible with such arrangements, resulting in discomfort to the patient, difficulties for the nurse in fitting the stocking and, possibly most seriously, reduced efficiency of the device.
Although the use of Velcro (TM) straps overcomes many of these disadvantages, patients are often disturbed by the noisy creaking of such straps during the intermittent inflation and deflation of such stockings. This may be a major drawback especially since such stockings may have to be worn at night.
The term "stocking" generally refers to a garment which encompasses the lower part of the leg not necessarily including the foot.
In accordance with the present invention, an intermittent compression stocking comprises at least one inflatable cell and has a portion which adheres to a further portion of the stocking to secure the stocking in position.
Preferably, the adhering portion is arranged on one surface of a flap extending from one side of an inflatable cell.
It will be appreciated that the use of an adhesive portion to secure the stocking in position around the patient's leg overcomes the problems hitherto experienced with prior art arrangements. In particular, intermittent compression stockings in accordance with the present invention may be easily adjusted to fit comfortably around the patient's leg.
An embodiment of the invention will now be described with reference to the accompanying drawings in which Fig. 1 is a plan view of an intermittent compression stocking in accordance with the present invention and Fig. 2 is a cross-sectional schematic view of such an intermittent compression stocking.
Referring now to Figs 1 and 2, an intermittent compression stocking, indicated generally at 1, is shown which is suitable for wrapping around the calf of a patient. The stocking comprises a first PVC sheet 17 and a somewhat larger second PVC sheet lδ. First PVC sheet 17 is welded around its periphery to the second PVC sheet 18. A further weld 20 between the two sheets is provided whereby an inflatable cell 2 having the first and second PVC sheets as upper and lower surfaces and edges defined by the further weld 20 is obtained. By providing the further weld 20, the size of the inflatable cell 2 may be minimised to that providing a sufficient intermittent compression action and consequent thereapeutic effect. This is particularly advantageous since it reduces the size and the cost of the compressor system (not shown) required for the stocking.
First and second flaps, 12 and 14 respectively, are formed by the portions of the second P VC sheet 18 which do not form a surface of the inflatable cell 2. A random fibre sheet 19 covers a portion of the surface of the second PVC sheet 18 which is inward facing when the stocking is in position on a patient's calf. The random fibre sheet contacts the patient's skin in use and is made of a moisture absorbing material for greater patient comfort. In the present embodiment, the random fibre sheet 19 is disposed under second flap 14 and inflatable cell 2. A water based pressure sensitive latex adhesive is applied to a portion 15 of first flap 12 of the second PVC sheet 18. The adhesvie portion is covered with a silicone backed paper 16.
A grommet 5 is welded onto the outer surface of first PVC sheet 17 and lines the hole (not shown) in first PVC sheet 17 through which air passes to and from the inflatable cell 2. A male/female connector 5 is connected to the grommet, there being a small length of tubing attached to the connector, terminating in a connector 7. Connector 7 is adapted to mate with second connector 8, itself having a male/male connector 9 to a further length of tubing 10 terminating in third connector 11. Third connector 11 is adapted to be connected to a compressor system (not shown) . Providing the short length of tubing 6 terminating in connector 7 allows the patient to readily disconnect the stocking from the compressor system and walk unincumbered by lengths of tubing. First and second connectors 7 and 8, are therefore designed to be particularly easily disconnected and reconnected.
In use, the stocking is wrapped around the patient's calf so that the random fibre sheet 19 is placed in contact with the patient's skin. The silicone backed paper 16 is then removed and the adhesive portion 15 of first flap 12 pressed to a portion of second flap 14. Tubing 10 is then connected to the stocking and a compressor (not shown) .
The stocking could be made wholly or partially from PVC sheets which have the property of "clinging" to a.surface which is substantially smooth or to a further PVC sheet having identical properties. In this way, it would be possible to dispense with the use of an adhesive and silicone backing paper. A PVC sheet having such a property would be extremely useful in that during normal handling the stocking would not be adhesive to the touch but would display the required adhesive property when wrapped around a patient's calf so that the PVC sheet makes contact with itself or with a further such sheet. Naturally, a PVC sheet displaying this property should not contain any substance which would be detrimental to the health of the patient as a result of the relatively long periods for which it is in contact with the patient's skin.

Claims

1. An intermittent compression stocking comprising at least one inflatable cell and having a portion which adheres to a further portion of the stocking to secure the stocking in position.
2. An intermittent compression stocking as claimed in claim 1 wherein the adhering portion is arranged on one surface of a flap extending from one side of an inflatable cell.
3. An intermittent compression stocking as claimed in claim 2 wherein the adhering portion is adapted to be secured to a further flap extending from the other side of the said inflatable cell.
4. An intermittent compression stocking as claimed in any preceding claim further comprising a moisture absorbing sheet arranged, in use, to contact the patient's skin.
5. An intermittent compression stocking as claimed in any preceding claim wherein the inflatable cell is formed of a pair of PVC sheets welded together and further welded together at a first set of welds to define a cell of predertermined size.
6. An intermittent compression stocking as claimed in claim 5 wherein the PVC sheets are arranged to further form a flap which acts as the adhering portion of the stocking.
7. An intermittent compression stocking as claimed in claim 6 wherein the PVC sheet is formulated such that it adheres to itself.
8. An intermittent compression stocking as claimed in any of claims 5, 6 or 7 wherein the cell size is determined to be the minimum needed for the required therapeutic purpose.
9. An intermittent compression stocking substantially as hereinbefore described with reference to the accompanying drawings.
