Claims
- 1. The process for forming a radiation-absorbing glove having a wall thickness between about 6 and 20 thousands of an inch which comprises the steps of:
- forming a mixture comprising high specific gravity metal or metal compound particles and a latex composition, said latex composition including rubber particles suspended in a liquid carrier, said metal or metal compound particles comprising between about 5 and 10 volume percent of said mixture, and said mixture having a consistency such that said metal or metal compound particles will readily settle out of said mixture and entrapped air will readily bubble out of said mixture;
- agitating said mixture so as to disperse said metal or metal compound particles substantially uniformly throughout said latex composition without the entrapment of air in said mixture;
- depositing said agitated mixture onto a glove form;
- coagulating said deposited mixture on said glove form; and
- curing said coagulated mixture on said glove form to form a glove;
- said glove being formed so as to comprise at least one layer comprising a mixture of cured rubber latex and high specific gravity metal or metal compound particles, said at least one layer being pin-hole free and being capable of absorbing between about 50 and 80 percent of incident radiation of between about 60 to 100 KVP, and said glove being sufficiently flexible to permit it to be used with dexterity during a medical procedure.
- 2. The process of claim 1 wherein said mixture is formed in a container and has a top surface, and wherein substantially the entire top surface of said mixture is sealed from the atmosphere during said agitating step.
- 3. The process of claim 1 wherein said mixture is formed in a container and has a top surface, said container having a bottom defining an opening, and wherein said agitating step comprises utilizing low shear pumping means to circulate said mixture from said opening to a point near to, but below, said top surface of said mixture, the rate of circulation being sufficient to maintain said high specific gravity metal or metal compound particles in substantially uniform suspension within said latex composition and being lower than the rate at which air is entrained by said top surface.
- 4. The process according to claim 1 wherein said high specific gravity metal or metal compound particles comprise tungsten particles.
- 5. The process according to claim 2 wherein said high specific gravity metal or metal compound particles comprise tungsten particles.
- 6. The process according to claim 3 wherein said high specific gravity metal or metal compound particles comprises tungsten particles.
- 7. The process for forming a radiation-absorbing glove having a wall thickness between about 6 and 20 thousands of an inch which comprises the steps of:
- forming a mixture comprising high specific gravity metal or metal compound particles and a latex composition, said latex composition including rubber particles suspended in a liquid carrier, said rubber particles comprising between about 55 and 60 volume percent of said latex composition, and said metal or metal compound particles comprising between about 5 and 10 volume percent of said mixture;
- agitating said mixture so as to disperse said metal or metal compound particles substantially uniformly throughout said latex composition without the entrapment of air in said mixture;
- depositing said agitated mixture onto a glove form;
- coagulating said deposited mixture on said glove form; and
- curing said coagulated mixture on said glove form to form a glove;
- said glove being formed so as to comprise at least one layer comprising a mixture of cured rubber latex and high specific gravity metal or metal compound particles, said at least one layer being pin-hole free and being capable of absorbing between about 50 and 80 percent of incident radiation of between about 60 to 100 KVP, and said glove being sufficiently flexible to permit it to be used with dexterity during a medical procedure.
- 8. The process of claim 7 wherein said mixture is formed in a container and has a top surface, and wherein substantially the entire top surface of said mixture is sealed from the atmosphere during said agitating step.
- 9. The process of claim 7 wherein said mixture is formed in a container and has a top surface, said container having a bottom defining an opening, and wherein said agitating step comprises utilizing low shear pumping means to circulate said mixture from said opening to a point near to, but below, said top surface of said mixture, the rate of circulation being sufficient to maintain said high specific gravity metal or metal compound particles in substantially uniform suspension within said latex composition and being lower than the rate at which air is entrained by said top surface.
- 10. The process according to claim 7 wherein said high specific gravity metal or metal compound particles comprise tungsten particles.
- 11. The process according to claim 8 wherein said high specific gravity metal or metal compound particles comprise tungsten particles.
- 12. The process according to claim 9 wherein said high specific gravity metal or metal compound particles comprise tungsten particles.
