Method and apparatus for storing bone cement components
View Patent ↗A container for storing a liquid component of bone cement. The container includes a flexible film sealed about its periphery to define a cavity. The cavity has a first layer, a second layer, and a vinyl barrier layer between the first layer and the second layer. The cavity is operable to store the liquid component of bone cement.
1. A container for storing a liquid component of bone cement comprising:
a flexible film sealed about its periphery to define a cavity, said flexible film includes an inner layer, an outer layer, a vinyl barrier layer between said inner layer and said outer layer, a first nylon layer between said inner layer and said vinyl barrier layer, and a second nylon layer between said outer layer and said vinyl barrier layer, said cavity includes:
a neck portion having a sealed end;
a main body portion having a width that is larger than said neck portion;
a stent extending from a first terminal end to a second terminal end and seated in said neck portion to facilitate withdrawal of the liquid component of bone cement from said cavity, said stent extending from said first terminal end to said second terminal end only within less than an entirety of said neck portion and is proximate to said sealed end, said stent permits passage of the liquid component of bone cement there through; and
the liquid component of bone cement.
2. The container of claim 1 , wherein said flexible film includes a front flexible film panel and a rear flexible film panel, said front flexible film panel is sealed to said rear flexible film panel;
wherein said stent is seated between said front flexible film panel and said rear flexible film panel to separate said front flexible film panel from said rear flexible film panel.
3. The container of claim 1 , wherein said flexible film is selected from Cryovac® T60XXB series film.
4. The container of claim 1 , wherein said cavity includes a tapered portion between said neck portion and said main body portion.
5. The container of claim 1 , wherein said stent includes a hollow, cylindrical tube.
6. A container for storing a liquid component of bone cement comprising:
a flexible film sealed about its periphery to define a cavity, said flexible film including:
an inner layer;
an outer layer;
a vinyl barrier layer between said inner layer and said outer layer;
a first nylon layer between said inner layer and said vinyl barrier layer;
a second nylon layer between said outer layer and said vinyl barrier layer: and
the liquid component of bone cement stored within said cavity.
7. The container of claim 6 , wherein said inner layer includes linear low density polyethylene.
8. The container of claim 6 , wherein said flexible film is selected from Cryovac® T60XXB series material.
9. The container of claim 6 , wherein said flexible film-includes Cryovac® T6050B material.
10. The container of claim 6 , wherein said flexible film includes a single sheet of flexible material that is folded at least at one point to define said cavity.
11. The container of claim 6 , wherein said container has a tapered portion at least proximate to a neck portion.
12. The container of claim 11 , wherein said flexible film includes a pre-cut portion at said neck portion.
13. The container of claim 11 further comprising a stent in said neck portion.
14. The container of claim 11 , wherein said stent includes a hollow, cylindrical tube.
15. The container of claim 6 , wherein said cavity has a neck portion, a main body portion, and a tapered portion between said neck portion and said main body portion, said container further comprising:
a stent that extends only within said neck portion;
a port that is seated in said neck portion to facilitate insertion of the liquid component into said cavity, said port extends from within said cavity, said stent is confined to an area between said port and said main body portion;
wherein said cavity is operable to store the liquid component of bone cement.
16. The container of claim 6 , further comprising:
a neck portion of said cavity;
a main body portion of said cavity having a width that is larger than said neck portion; and
a stent seated in said neck portion to facilitate withdrawal of the liquid component of bone cement from said cavity, said stent extends only within said neck portion and is proximate to said sealed end, said stent permits passage of the liquid component of bone cement there through.
17. The container of claim 16 , further comprising a port that cooperates with a delivery device to facilitate insertion of the liquid component of bone cement into said cavity, said port is separate from said stent.
18. The container of claim 6 , wherein said outer layer includes polypropylene.
19. The container of claim 6 , further comprising positioning a first adhesive between said inner layer and said first nylon layer; and
a second adhesive between said outer layer and said second nylon layer.
20. The container of claim 6 , wherein said vinyl barrier layer includes ethylene vinyl alcohol.
21. A method of filling a container with a liquid component of bone cement comprising:
mounting a stent and a port in a neck portion of the container, the neck portion having a width that is smaller than a main body portion of the container, the stent is between the main body portion and the port, the port extends from the container;
loading the liquid component of bone cement into the main body portion through the port and the stent;
sealing the neck portion between the port and the stent; and
separating the port from the container.
22. The method of claim 21 , further comprising sealing a front flexible film panel to a rear flexible film panel to form the container.
23. The method of claim 21 , further comprising forming the container with a flexible film.
24. The method of claim 23 , wherein the flexible film includes Cryovac® T60XXB series film.
25. The method of claim 23 , wherein the flexible film includes an ethylene vinyl alcohol barrier layer and a nylon layer on each side of the ethylene vinyl alcohol barrier layer.
26. The method of claim 21 , wherein loading the liquid component of bone cement includes loading methyl methactylate monomer into the main body portion.
27. The method of claim 21 , wherein the stent includes a hollow, cylindrical tube.
28. The method of claim 21 , wherein the port includes a hollow, cylindrical tube.
