Abstract

Graded Compression Anti-thrombosis Stockings which allows easy identification of the pressure they generate on the patient's legs. Based on the concept that stretching of the fabric is related to the tension, and tension is in turn related to the pressure generated by the stocking, it is possible to incorporate a form of marker in the stocking to assess the amount of stretch. The pressure profile of the stocking can then be assessed on individual patient to maximise the efficacy of the garment. Alternatively, the Stockings may incorporate electronic or pneumatic pressure sensitive material.

Description

Self Monitorine Graded Comoression Anti-thrombosis Stockings This invention relates to the use of medical graded compression stockings in the prevention of deep vein thrombosis (DVT).
Graded compression stockings are extensively used to prevent the formation of potentially dangerous blood clots in the legs (deep vein thrombosis or DVT) of medical patients. When correctly applied, they should generate a graded pressure gradient along the leg, being tighter at the ankle and becoming gradually less tight towards the upper thigh. The ideal pressure profile should be 18mmHg at the ankle, 1 4mmHg at the calf, 8mmHg at the knee, 1 OmmHg at the lower thigh and 8mmHg at the upper thigh. Human anatomy varies and patients' legs do not conform to one uniform size and shape. The existing designs of graded compression stockings do provide a wide range in lengths and sizes to account for the natural variations.
However, it is still not possible to determine whether the appropriate pressure profile has indeed been achieved on the actual individual patient (in vivo pressure profile). There is sufficient evidence to show that some Graded Compression Stockings generated inappropriate and even reverse pressure gradient ( tighter at the top of the leg and less tight towards the foot) on some patients. In such cases the stocking can have a deleterious effect, promoting thrombus formation instead of preventing it.
Our new design is based on the concept that tension in the fabric of the stocking is directly related to the pressure it generates. Tension itself is also related to the amount of stretching of the fabric. Therefore by placing markers along the length of the stocking, it is possible to identify the amount of stretching and estimate the pressure profile.
Several types of markers can be used: (1) A continuous or several separate coloured stripes of a pre-determined width marking the stocking along its length. Stretching of the fabric will increase the width of the stripes. The more the fabric is stretched, the wider the stripes will appear. An estimation of the pressure profile can then be made by inspecting the width of the stripes. (Figs 1 and 2) (2) A coloured pattern (e.g. coloured spots with a regular distance apart) can be incorporated into the fabric along the length of the stocking. The amount of stretch can be identified as the distance between spots increases. (Fig. 3) (3) Electronic or pneumatic pressure sensitive material can be incorporated into the stocking and the pressure profile identified by electronic means. (Fig. 4) Our design is applicable to knee-length, thigh-length and full-length stockings.

Claims
1. The design of a self monitoring anti-thrombosis graded compression stocking that incorporates a mechanism by which the in vivo pressure profile can be estimated.
2. A self monitoring anti-thrombosis graded compression stocking as claimed in claim 1 in which the pressure sensitive mechanism is maufactured in the form of a continuous coloured stripe marking the length of the stocking.
3. A self monitoring anti-thrombosis graded compression stocking as claimed in claim 1 in which the pressure sensitive mechanism is manufactured in the form of several coloured stripes marking the length of the stocking.
4. A self monitoring anti-thrombosis graded compression stocking as claimed in claim 1 in which the pressure sensitive mechanism is manufactured in the form of coloured pattern and the pressure profile estimated as a fiction of the deformation of the pattern.
5. A self monitoring anti-thrombosis graded compression stocking as claimed in claim 1 in which the pressure sensitive mechanism is manufactured in the form of electronic pressure sensitive device.
6. A self monitoring anti-thrombosis graded compression stocking as claimed in claim 1 in which the pressure sensitive mechanism is manufactured in the form of pneumatic pressure sensitive device.
7. A self monitoring anti-thrombosis graded compression stocking as claimed in claim 1 in which the pressure sensitive mechanism is manufactured in the form as illustrated in Figs. 1-4.
