Abstract
Abstract A garment to provide pulsating pressure to a lower human extremity for aiding blood circulation in the extremity and having an outer nonelastic plastic envelope sealed to an internal relatively soft envelope providing an air space therebetween for the application of pulsating pressure uniformly to a limb inserted within the inner envelope. The inner envelope has a common seam along part of its length with the outer envelope to prevent inflation pressure from displacing the two envelopes. A system of apertures in the inner envelope provide for a limited gaseous passage of air from the pressurized space between the two envelopes to the surface of a limb encased within to provide breathing air for the skin.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
137 words
In a garment for an animal body extremity consisting of inner and outer envelopes forming a pocket therebetween for the periodic application of fluid pressure to stimulate flow of vascular fluids, the combination in said inner envelope comprising: a. A soft compliant envelope material readily moldable to an animal body under light pressure; b. An open-ended proximal portion to said inner envelope; c. A closed distal portion to said inner envelope; d. A fluid impermeable seam connecting the open end of said proximal portion to said outer envelope; e. A longitudinal seam along the length of said proximal portion connected to said outer envelope; and, f. A complete separation between the distal portion of said inner envelope and said outer envelope whereby the distal portion of said inner envelope has freedom of movement within said outer envelope.
Claim 2
Dependent Claim
137 words
In a garment for an animal body extremity consisting of inner and outer envelopes forming a pocket therebetween for the periodic application of fluid pressure to stimulate flow of vascular fluids, the combination in said inner envelope comprising: a. A soft compliant envelope material readily moldable to an animal body under light pressure; b. An open-ended proximal portion to said inner envelope; c. A closed distal portion to said inner envelope; d. A fluid impermeable seam connecting the open end of said proximal portion to said outer envelope; e. A longitudinal seam along the length of said proximal portion connected to said outer envelope; and, f. A complete separation between the distal portion of said inner envelope and said outer envelope whereby the distal portion of said inner envelope has freedom of movement within said outer envelope.
Claim 3
Dependent Claim
39 words
In a garment according to claim 1 the combination in which said distal portion is perforated by a plurality of small apertures for allowing a gaseous flow between said inner envelope and along the surface of said animal body.
Claim 4
Dependent Claim
20 words
In a garment according to claim 1 the combination in which said distal portion is shaped to accomodate a foot.
Claim 5
Dependent Claim
52 words
In a garment according to claim 1, the combination with said inner envelope of a flexible tube extending from the exterior through said open ended proximal portion and extending into the proximity of said closed distal portion whereby to provide a flow of ventilating gas between said first envelope and said limb.
Claim 6
Dependent Claim
138 words
A garment for enhancing blood circulation in an animal body comprising: a. A first envelope of soft compliant synthetic resin open at one end and closed at the other for insertion of an animal limb; b. A second envelope of semirigid synthetic resin exterior to said first envelope and sealed to said first envelope at said open end to form a pocket therebetween; c. Port means connected to said second envelope for introducing gas between said second envelope and said first envelope so as to compress said first envelope against said limb; and, d. A plurality of pores in said first envelope in the proximity of the closed end for providing a ventilating flow of gas between said first envelope and said limb, the total area of said pores being less than the area of said port means.
Claim 7
Dependent Claim
138 words
A garment for enhancing blood circulation in an animal body comprising: a. A first envelope of soft compliant synthetic resin open at one end and closed at the other for insertion of an animal limb; b. A second envelope of semirigid synthetic resin exterior to said first envelope and sealed to said first envelope at said open end to form a pocket therebetween; c. Port means connected to said second envelope for introducing gas between said second envelope and said first envelope so as to compress said first envelope against said limb; and, d. A plurality of pores in said first envelope in the proximity of the closed end for providing a ventilating flow of gas between said first envelope and said limb, the total area of said pores being less than the area of said port means.
Claim 8
Dependent Claim
158 words
A garment having an open end and a closed end for enhancing blood circulation in an animal body comprising: a. A first envelope of soft compliant synthetic resin open at one end and closed at the other for insertion of an animal limb; b. A second envelope of semirigid synthetic resin exterior to said first envelope and sealed to said first envelope at said open end to form a pocket therebetween; c. Port means connected to said second envelope proximate to said closed end for introducing gas between said second envelope and said first envelope so as to compress said first envelope against said limb; and, d. A plurality of apertures located in said garment proximate to said open end, whereby on the application of fluid pressure at said port means, fluid flow through said apertures provides a pressure gradient entending from a relatively high pressure at said closed to a relatively low pressure at said open end.
Claim 9
Dependent Claim
158 words
A garment having an open end and a closed end for enhancing blood circulation in an animal body comprising: a. A first envelope of soft compliant synthetic resin open at one end and closed at the other for insertion of an animal limb; b. A second envelope of semirigid synthetic resin exterior to said first envelope and sealed to said first envelope at said open end to form a pocket therebetween; c. Port means connected to said second envelope proximate to said closed end for introducing gas between said second envelope and said first envelope so as to compress said first envelope against said limb; and, d. A plurality of apertures located in said garment proximate to said open end, whereby on the application of fluid pressure at said port means, fluid flow through said apertures provides a pressure gradient entending from a relatively high pressure at said closed to a relatively low pressure at said open end.
