Integrated bone cement mixing and dispensing system method

Claim 2

A process for preparing and delivering mixed bone cement to any desired site using a single, multi-purpose vessel comprising the steps of: A. mixing bone cement components in a mixing zone of said multi-purpose vessel until the cement components are fully intermixed; B. exposing the mixed bone cement to movement control means contained in a delivery section of the multi-purpose vessel; C. activating the movement control means to remove the bone cement from the mixing zone while drawing the mixed cement through the delivery section; and D. forcing the bone cement through an outlet portal of the delivery section under pressure by continuously activating the movement control means; whereby cement is mixed and delivered in a single integrated assembly without the exposure of cement to the user during the process.

Claim 3

The process defined in claim 1, wherein said mixing step is performed by rotating blade means formed on an elongated shaft by attaching said shaft to one selected from the group consisting of electrically powered drivers and hand cranks.

Claim 4

The process defined in claim 2, comprising the additional step of: E. measuring the number of rotations of said support shaft to determine when sufficient rotation of the blades has occurred to provide fully intermixed bone cement; and F. providing an indication to the operator that the bone cement is prepared.

Claim 5

The process defined in claim 1, comprising the additional step of: E. adding the bone cement components to the mixing zone of the multi-purpose vessel prior to initiating the mixing step.

Claim 6

The process defined in claim 4, comprising the additional step of F. employing a removable cover to gain access to the interior of the mixing zone and to seal the mixing zone from external contamination.

Claim 7

The process defined in claim 1, comprising the additional steps of: E. positioning the outlet portal of the delivery section in direct association with the desired site; and F. delivering the mixed bone cement directly to the desired receiving member.

Claim 8

The process defined in claim 6, comprising the additional steps of: E. connecting an extension tube to the outlet portal of the delivery section; F. positioning the distal end of the extension tube at the desired site; and G. forcing the mixed bone cement through the extension tube for delivery to the desired site.

Claim 9

A process for preparing and delivering mixed bone cement directly to any desired site using a single, multi-purpose vessel comprising the steps of: A. forming a multi-purpose vessel having a mixing zone and a delivery section interconnected with each other for movement between a first position wherein said mixing zone and delivery section are sealed from each other and a second position wherein said mixing zone and delivery section are in communication with each other; B. moving said multi-purpose vessel into its first position; C. mixing bone cement components in the mixing zone of said multi-purpose vessel until fully intermixed; D. moving said multi-purpose vessel into said second position for bringing the mixing zone into communication with said delivery section and exposing the mixed bone cement to movement control means contained in the delivery section; E. activating the movement control means to remove the bone cement from the mixing zone while drawing the mixed cement through the delivery section; and F. forcing the bone cement through an outlet portal of the delivery section under pressure by continuously activating the movement control means; whereby cement is mixed and delivered in a single integrated assembly without the exposure of cement to the user during the process.

Claim 10

A process for preparing and delivering mixed bone cement directly to any desired site using a single, multi-purpose vessel comprising the steps of: A. forming a multi-purpose vessel having a mixing zone and a delivery section interconnected with each other for movement between a first position wherein said mixing zone and delivery section are sealed from each other and a second position wherein said mixing zone and delivery section are in communication with each other; B. moving said multi-purpose vessel into its first position; C. mixing bone cement components in the mixing zone of said multi-purpose vessel until fully intermixed; D. moving said multi-purpose vessel into said second position for bringing the mixing zone into communication with said delivery section and exposing the mixed bone cement to movement control means contained in the delivery section; E. activating the movement control means to remove the bone cement from the mixing zone while drawing the mixed cement through the delivery section; and F. forcing the bone cement through an outlet portal of the delivery section under pressure by continuously activating the movement control means; whereby cement is mixed and delivered in a single integrated assembly without the exposure of cement to the user during the process.
