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: 11
Claim 1
Independent Claim 112 words
A method of making a surgical glove (10) including 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 a stretchable, air and water impermeable material (16); disposing a hand shaped layer Z(18) of a flexible armor fiber (18) on the dorsal side (30) of the shell (24) prior to complete curing the liqud (34); dipping the shell (24) into the liquid (34) a second time to embed the armor material (18) within the liquid (34); and curing the liquid (34) to the stretcable, air and water impermeable material (16).
Claim 2
Independent Claim 112 words
A method of making a surgical glove (10) including 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 a stretchable, air and water impermeable material (16); disposing a hand shaped layer Z(18) of a flexible armor fiber (18) on the dorsal side (30) of the shell (24) prior to complete curing the liqud (34); dipping the shell (24) into the liquid (34) a second time to embed the armor material (18) within the liquid (34); and curing the liquid (34) to the stretcable, air and water impermeable material (16).
