Abstract

A fluid delivery system for dispensing a liquid from a sealed container directly into a closed chamber comprises a container containing a liquid component of bone cement and plugged with a plug, and a closed chamber comprising a receiving port for receiving the sealed container, wherein the receiving port is configured to receive the liquid component in direct response to manual insertion of the sealed container through the receiving port using an open loop system.

Claims

1. A sealed container comprising:

a housing comprising an open end and configured for containing a liquid monomer, the housing also being configured for being telescopically mounted onto a receiving port of a mixing chamber whereby at least a portion of the receiving port is received within the housing; and

a sealing member located in the open end and configured to plug the open end, wherein the sealing member includes a self-rupturing mechanism having a closed state and an open state, the sealing member being slidable along a length of the housing while maintaining a seal along a perimeter of the sealing member;

wherein when the self-rupturing mechanism is in the open state, the liquid monomer flows out of the housing, and wherein the self-rupturing mechanism includes a burst valve or a collapsible orifice; and

wherein the housing includes screw threads on a central portion along a length of the housing configured to advance the housing through the receiving port of the mixing chamber by threaded rotation.

2. The sealed container according to claim 1, wherein the self-rupturing mechanism includes a burst valve.

3. The sealed container according to claim 1, wherein the self-rupturing mechanism includes a collapsible orifice.

4. The sealed container according to claim 3, wherein the collapsible orifice opens in response to a pressure of the liquid in the housing increasing to a predetermined threshold pressure exerted on the sealing member.

5. The sealed container according to claim 1, wherein the housing contains liquid monomer.

6. The sealed container according to claim 1, wherein the housing is configured to contain approximately 5 ml to 50 ml of a liquid monomer.

7. The sealed container according to claim 1, wherein the housing has a tubular shape.

8. The sealed container according to claim 1, wherein the housing is fabricated from a rigid material.

9. The sealed container according to claim 7, wherein the housing is fabricated from at least one of glass or plastic.

10. The sealed container according to claim 1, wherein the sealing member is configured to slide along a length of the housing while maintain a seal along a perimeter of the sealing member.

11. The sealed container according to claim 1, wherein the housing is fabricated from a material that is transparent relative to the liquid monomer and further comprises scale marks on the housing configured for manually to allow a user to monitor the volume of the liquid in the housing.

12. The sealed container according to claim 1, further comprising a liquid monomer suitable for mixing with a polymer to form a PMMA cement located within the housing.

13. The sealed container according to claim 12, whereby advancement of the housing through a receiving port of a mixing chamber by threaded rotation causes the sealing member to slide away from the open end and move from a closed state to an open state and cause liquid monomer to flow out of the housing.

14. A sealed container comprising:

a housing comprising an open end and configured for containing a liquid monomer;

a liquid monomer suitable for mixing with a polymer to form a PMMA cement located within the housing; and

a sealing member configured to plug the open end, wherein the sealing member includes a self-rupturing mechanism having a closed state and an open state and wherein the sealing member is configured to slide along a length of the housing while maintaining a seal along a perimeter of the sealing member;

wherein when the self-rupturing mechanism is in the open state, the liquid monomer flows out of the housing, and wherein the self-rupturing mechanism includes a burst valve or a collapsible orifice; and

wherein the housing configured for advancing through a receiving port of a mixing chamber whereby the receiving port causes the sealing member to slide away from the open end and move from a closed state to an open state and cause liquid monomer flow out of the housing.

15. The sealed container according to claim 14, wherein the housing is configured for being telescopically mounted onto a receiving port of a mixing chamber.

16. The sealed container according to claim 14, wherein the housing includes screw threads configured for advancing the container through a receiving port of a mixing chamber by threaded rotation.

17. The sealed container according to claim 14, wherein the housing is fabricated from a material that is transparent relative to the liquid monomer.

18. The sealed container according to claim 17, further comprising scale marks on the housing configured for manually to allow a user to monitor the volume of the liquid in the housing.
