Abstract

Abstract A surgical glove (10) includes a ventral side (12) and a dorsal side (14) integrally connected thereto. The sides (12,14) include a thin layer (16) of stretchable air and water impermeable material and the dorsal side (14) includes a layer (18) of flexible armor (18) embedded in the stretchable air and water impermeable material (16). A method of making the surgical glove (10) includes the steps of dipping a mold shell (24) having the configuration of a human hand with a ventral side and a dorsal side (30) into a liquid (34) which is curable to the stretchable air and water impermeable material (16). A hand shaped layer (18) of the flexible armor is disposed on the dorsal side (30) of the shell (24) prior to curing the liquid (34). The shell (24) is dipped into the liquid (34) a second time to embed the fiber (18) within the liquid (34). Finally, the liquid ( 34) is cured to the stretchable air and water impermeable material (16).

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 104 words
A surgical glove (10) comprising: a ventral side (12) and a dorsal side (14) integrally connected to said ventral side (12), said sides (12,14) including a thin layer (16) of stretchable air and water impermeable material, and characterized by said dorsal side (14) including a layer (18) of flexible armor material embedded in said stretchable, air and water impermeable material (16) for preventing cutting through said material (16) to retain the impermeability of said dorsal side (14) in a sharp tool environment and said ventral side comprising a thin tactilly sensitive layer providing the combination of cut protection with tactile sensitivity for surgical maneuvers.
Claim 2
Dependent Claim 104 words
A surgical glove (10) comprising: a ventral side (12) and a dorsal side (14) integrally connected to said ventral side (12), said sides (12,14) including a thin layer (16) of stretchable air and water impermeable material, and characterized by said dorsal side (14) including a layer (18) of flexible armor material embedded in said stretchable, air and water impermeable material (16) for preventing cutting through said material (16) to retain the impermeability of said dorsal side (14) in a sharp tool environment and said ventral side comprising a thin tactilly sensitive layer providing the combination of cut protection with tactile sensitivity for surgical maneuvers.
Claim 3
Dependent Claim 18 words
A glove as set forth in claim 1 further characterized by said armor material comprising interwoven fibers (18).
Claim 4
Dependent Claim 33 words
A glove as set forth in claim 2 further characterized by said interwoven fibers defining intensities therebetween, said thin layer of said impermeable material being disposed throughout the interstices of said fibers (18).
Claim 5
Dependent Claim 18 words
A glove as set forth in claim 3 further characterized by said fibers interwoven into a stretchable cloth.
Claim 6
Dependent Claim 18 words
A glove as set forth in claim 4 further characterized by said fibers (18) being a synthetic fiber.
Claim 7
Dependent Claim 16 words
A glove as set forth in claim 5 further characterized by said fibers (18) being nylon.
Claim 8
Dependent Claim 18 words
A glove as set forth in claim 5 further characterized by said fibers (18) being an aramid fiber.
Claim 9
Dependent Claim 17 words
A glove as set forth in claim 1 further characterized by said impermeable material (16) being latex.
Claim 10
Dependent Claim 47 words
A glove as set forth in claim 1 further characterized by said dorsal side (14) of said glove (10) including finger portions (20) and a backhand portion (22), said armor material including fibers (18) extending over said finger portions (20) and partially over said backhand portion (16).
