Abstract
A therapeutic stocking comprising, a first circumferential segment for placement on the leg below the knee, with the first segment extending from the ankle to a point slightly below the knee. The first segment exerts a compressive pressure on the wearer's leg gradually decreasing from the ankle to said point below the knee. The stocking has a second circumferential segment for placement on the leg above the knee, with the second segment extending from a point slightly above the knee to the upper thigh. The method of placement of a therapeutic stocking on a wearer's leg includes the steps of measuring the circumference of the wearer's leg at two locations, placing an elastic fabric panel having overlapping side edges about the wearer's leg, the upper and lower ends of the panel having indicia representing a number of possible selected circumferential measurements of a wearer's leg, and securing the side edges of the panel together with the side edges overlapped to match the two previously determined circumferential measurements of the wearer's leg. The second segment exerts a compressive pressure on the wearer's leg gradually decreasing from said point above the knee to the upper thigh.

Description
Background of the Invention
The present invention relates to elastic garments, and more particularly to therapeutic stockings.
In the recent past, therapeutic stockings have been prescribed on a relatively wide scale to prevent possible embolism in a patient. When a patient is confined to bed, for example, after an operation, the likelihood of thrombis is markedly increased due to a decrease in the velocity of blood flow in the patient's legs during confinement. Therapeutic or anti-embolism stockings cause application of a compressive pressure against the patient's leg which gradually decreases from the ankle toward the upper part of the leg. Such stockings increase the velocity of blood flow in the legs, and minimize the possibility of thromboembolism.
It has been found that the prior stockings have been frequently difficult to place on the patient's leg by the hospital personnel. Also, it is desirable to avoid restrictive pressures on the veins in the sensitive popliteal space in the knee region. A stocking which exerts a reduced pressure in the knee region is disclosed in U.S. Pat. No. 3,889,494, incorporated herein by reference.
Summary of the Invention
A principal feature of the present invention is the provision of an improved therapeutic stocking of simplified construction.
The stocking of the present invention comprises, a first circumferential segment for placement on the leg below the knee, with the first segment extending from the ankle to a point slightly below the knee and covering the calf. The first segment comprises a knitted fabric including an elastomeric yarn which exerts a compressive pressure on the wearer's leg gradually decreasing from the ankle to said point below the knee. The stocking has a second circumferential segment for placement on the leg above the knee, with the second segment extending from a point slightly above the knee to the upper thigh and covering the lower thigh. The second segment comprises a knitted fabric including an elastomeric yarn which exerts a compressive pressure on the wearer's leg gradually decreasing from said point above the knee to the upper thigh.
A feature of the present invention is that the stocking is more easy to apply to a patient's leg than prior stockings.
Another feature of the invention is that the stocking does not exert pressure on the veins in the sensitive popliteal space.
Still another feature of the invention is that the first and second segments may comprise panels which are releasably secured about the wearer's leg.
Yet another feature of the invention is that the panels may be adjusted to the wearer's leg depending upon the circumference of the leg.
Further features will become more fully apparent in the following description of the embodiments of this invention and from the appended claims.
Description of the Drawings
In the drawings:
FIG. 1 is a perspective view of one embodiment of the stocking of the present invention;
FIG. 2 is a perspective view of another embodiment of the stocking of the present invention; and
FIG. 3 is a perspective view illustrating the stocking of FIG. 2 as applied to a wearer's leg.
Description of the Preferred Embodiments
Referring now to FIG. 1, there is shown a therapeutic stocking generally designated 10 having a lower first circumferential generally cylindrical segment 12, and an upper second circumferential generally cylindrical segment 14. As shown, the first segment 12 is placed on the leg below the knee, and the second segment 14 is placed on the leg above the knee.
The first segment 12 extends from the ankle to a point slightly below the knee and covers the calf. The first segment 12 comprises a knitted fabric including an elastomeric yarn which exerts a compressive pressure on the wearer's leg gradually decreasing from the ankle to said point below the knee. The first segment 12 may have a pair of non-compressive welts 16 at the lower and upper ends of the first segment 12.
The second segment 14 extends from a point slightly above the knee to the upper thigh and covers the lower thigh. The second segment 14 comprises a knitted fabric including an elastomeric yarn which exerts a compressive pressure on the wearer's leg gradually decreasing from said point above the knee to the upper thigh, with the pressure at the point above the knee being less than the pressure at the point below the knee. The second segment 14 may have a pair of non-compressive welts 18 at the lower and upper ends of the second segment 14.
Thus, in accordance with the present invention, the stocking 10 exerts a compressive pressure which gradually decreases from the ankle to a point below the knee and from a point above the knee to the lower thigh. The stocking 10 of the present invention is more simple to place on a wearer's leg than prior stockings. Also, the stocking 10 of the present invention does not exert restrictive pressures on the veins in the sensitive popliteal space in the knee region.
Another embodiment of the present invention is illustrated in FIGS. 2 and 3, in which like reference numerals designate like parts. In this embodiment, the stocking 10 comprises a first lower panel 20 of elastic fabric for placement below the knee, and a second upper panel 22 of elastic fabric for placement above the knee.
The first and second panels 20 and 22 have a pair of opposed side edges 24a and 24b, and a pair of opposed end edges 26a and 26b connecting the side edges 24a and b. The panels 20 and 22 have a first loop fastening strip 28 extending along the side edge 24b on an inner surface 30 of the panels 20 and 22. Also, the panels 20 and 22 have a second hook fastening strip 32 extending along the side edge 24a on an outer surface 34 of the panels 20 and 22. The first and second fastening strips 28 and 32 may be of the type sold under the trademark Velcro. In an alternative form, the strip 28 may comprise a hook fastening strip and the strip 32 may be omitted, with the hook strip 28 being secured directly to the fabric of the stocking.
The lower first panel 20 has a sufficient width between the side edges 24a and b to encircle the leg below the knee in an overlapping relationship. The first panel 20 has a sufficient length between the end edges 26a and b to extend from the ankle to a point slightly below the knee. The second panel 22 has a sufficient width between the side edges 24a and b to encircle the leg above the knee in an overlapping relationship. The second panel 22 has a sufficient length between the end edges 26a and b to extend from a point slightly above the knee to the upper thigh.
With reference to FIG. 3, the first panel 20 is secured about the wearer's leg below the knee by use of the fastening strips 28 and 32, and the second panel 22 is secured about the wearer's leg above the knee through use of the fastening strips 28 and 32. As shown, the panels 20 and 22 may have indicia I at the lower and upper ends thereof to facilitate placement of the panels 20 and 22 about the wearer's leg. The indicia I may include vertical lines, as shown, along with numerals associated with the lines indicating the circumference of the wearer's leg in the region of the indicia I. Thus, the circumference of the wearer's leg may be measured by a suitable tape, and the panels 20 and 22 may be secured about the leg with the side edge 24b located at the appropriate indicia I associated with the numeral indicating the leg's circumference in the region of the indicia I.
When properly placed on the wearer's leg, the lower panel 20 exerts a compressive pressure which gradually decreases from the patient's ankle to the point below the knee, and the upper panel 22 exerts a compressive pressure against the wearer's leg which gradually decreases from the point above the knee to the upper thigh. As before, the stocking 10 of FIGS. 2 and 3 is more easy to place on the wearer's leg than prior stockings. Further, the stocking 10 of FIGS. 2 and 3 does not exert a restrictive pressure against the veins in the sensitive popliteal space in the knee region.
The foregoing detailed description is given for clearness of understanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to those skilled in the art.
