AI Technical Summary

Benefits of technology

The system effectively reduces swelling by applying controlled pressure that promotes lymphatic fluid flow without blocking veins, allowing for patient mobility and reducing treatment costs.

Problems solved by technology

This is due to the fact that should only one elastically deformable therapeutic pressure sleeve instead be used, this sleeve would have to be dimensioned to be initially tightly received over the limb, thus being difficult for the patient to comfortably slip on and off.

Embodiment Construction

[0053]FIG. 1 shows the therapeutic pressure sleeve apparatus 18 of the present invention fitted onto a patient's arm for treating lymphedema. (It is to be understood, however, that the present invention can also be fitted to the patient's leg, hand, foot or torso). As will be explained, sleeve 18 is preferably received within a secondary sleeve which exerts a pressure on sleeve 18 such that an increased therapeutic pressure is applied to the patient's body surface. Various embodiments exist for the secondary sleeve. For example, FIG. 2A shows a thin fabric compression sleeve 40 received over sleeve 18 and FIG. 2B shows an inflatable compression sleeve 50 received over sleeve 18.

[0054]As shown in FIG. 3, sleeve 18 is preferably made from a quadrangle of convoluted foam material 20 such as is widely used as an under-sheet lining on mattresses. Specifically, tapered quadrangle 20 of convoluted foam is cut as shown, with the sides 21 being angle-cut so that the edges meet flush when the...

Abstract

An apparatus for applying pressure to a body part comprising: a first sleeve comprising a multiplicity of pressure-applying resilient protrusions configured to apply a therapeutic pressure to a surface of the body part of a patient; and a second sleeve slidably received over the first sleeve, the second sleeve configured to apply a pressure to the first sleeve, thereby increasing the therapeutic pressure applied by the first sleeve on the limb.
