Pulsatile stocking and bladder therefor
First Claim
Patent Images
1. A device for use in applying pulsatile compression to a patient comprising:
- a porous air breathable circumferentially elastic tube; and
a panel secured at circumferentially spaced locations to an exterior of the tube to provide a bladder receiving cavity between the panel and the tube, said panel being substantially less elastic than the tube in a circumferential direction to restrict the circumferential stretching of only a portion of the device.

Abstract
A device for applying intermittent compression to a body member, such as a leg, of a patient is disclosed. This device has a highly elastic stocking of the antiembolism type with an inelastic external panel secured to a portion of the stocking'"'"'s circumference to provide a bladder cavity and restrict circumferential stretching of only a portion of the stocking. The inelastic panel has an openable structure, and internal bladder retaining pockets. An inflatable bladder includes an inner shaping panel causing the bladder to more readily conform to the shin area of the leg.

21. A device for applying pulsatile compression to a patient by means of an inflatable bladder within a cavity of a body support system, wherein the improvement comprises:
- a bladder having upper and lower panels secured to each other about their peripheries, and an inner shape defining panel within the bladder to control the shape of the bladder into a more anatomical shape during inflation.
