Claims
- 1. A stabilizer for a piston within a hollow syringe housing comprising:
a barrel defining a body with first end suitable for connecting to an adjoining surface of the piston and a second end suitable for connecting to a drive rod, first means for connecting the first end to the piston, second means for connecting the second end to the drive rod, and an extension from the body extending along and interferingly contacting the adjoining piston surface in order to maintain the piston against the inner surface of the hollow syringe housing.
- 2. The stabilizer as defined in claim 1 wherein the extension extends along the adjoining piston surface until it reaches the inner surface of the hollow syringe housing.
- 3. The stabilizer as defined in claim 1 wherein the first and second means for connecting comprise threaded connections.
- 4. The stabilizer as defined in claim 1 wherein the stabilizer is constructed from metal.
- 5. The stabilizer as defined in claim 1 wherein the stabilizer is constructed from a plastic material.
- 6. A stabilizer for a piston within a hollow syringe housing comprising:
a barrel defining a body with first end suitable for connecting to an adjoining surface of the piston and a second end suitable for connecting to a drive rod, first means for connecting the first end to the piston, second means for connecting the second end to the drive rod, an extension from the body extending along and interferingly contacting the adjoining piston surface and extending to the inner surface of the syringe, and the extension extending farther along and adjacent to the inner surface of the syringe such that the stabilizer/piston combination remains straight and aligned with the syringe body when the piston exerts pressure on a fluid being dispensed.
- 7. The stabilizer as defined in claim 6 further wherein the stabilizer is split longitudinally into two substantially equal portions, and further comprising means for joining the two portions together.
- 8. A method for stabilizer a piston within a hollow syringe housing comprising the steps of:
defining a barrel body with first end suitable for connecting to an adjoining surface of the piston and a second end suitable for connecting to a drive rod, connecting the first end to the piston, connecting the second end to the drive rod, and extending the body along and interferingly contacting the adjoining piston surface in order to maintain the piston against the inner surface of the hollow syringe housing, and further extending the body along and adjacent to the inner surface of the syringe such that the stabilizer/piston combination remains straight and aligned with the syringe body.
- 9. The method as defined in claim 8 further wherein the stabilizer is split longitudinally into two substantially equal portions, and further comprising the step of joining the two portions together.
