Syringe Devices, Components of Syringe Devices, and Methods of Forming Components and Syringe Devices

Abstract

A syringe device includes a syringe barrel and piston having a fluid passageway extending from a vial port. Another syringe device includes a syringe barrel, a piston sleeve and an insert. A channel extends along a side of the insert. A valve controls fluid communication between the channel and the syringe barrel. Another syringe device has a syringe barrel, a piston sleeve and an insert. A valve controls fluid communication between a compartment within the insert and the syringe barrel. A method of preparing a medication includes providing a component within a syringe barrel and another component within a compartment of a piston insert. A seal is over-molded onto a tip of the insert and an end of a piston sleeve. The sleeve is rotated relative to the insert to establish fluid communication between the compartment and the barrel chamber.

The invention claimed is: 
     
         1 . A syringe device comprising:
 a syringe barrel;   a piston having a first end insertable within the syringe barrel, and a second end opposing the first end; and   a container housing comprising a part disposed within the piston and configured to receive an end of the container in lengthwise orientation along a portion of the overall length of the piston.   
     
     
         2 . The syringe device of  claim 1  wherein the container housing defines an end of the piston. 
     
     
         3 . The syringe device of  claim 1  further comprising a container within the container housing. 
     
     
         4 . The syringe device of  claim 3  wherein the container is fixedly coupled within the container housing. 
     
     
         5 . The syringe device of  claim 3  wherein the container slidably engages the container housing. 
     
     
         6 . The syringe device of  claim 3  wherein the container is sealed. 
     
     
         7 . The syringe device of  claim 6  wherein the container encloses a medicant. 
     
     
         8 . The syringe device of  claim 7  wherein the medicant can be accessed while the container is within the housing. 
     
     
         9 . The syringe device of  claim 7  wherein the medicant can be released while the container is within the housing. 
     
     
         10 . The syringe device of  claim 1  wherein the container housing is substantially cylindrical.
