Biocompatible component with structural reinforcement

An analytical instrument system comprising a pump, wherein said pump further comprises a pump head having a reinforcement body comprising a reinforcing material, a pump chamber, and first and second apertures coupled with respective first and second fluid pathways therethrough, each fluid pathway extending between the first and second apertures and the pump chamber in the reinforcement body, wherein each fluid pathway has a diameter that is smaller than a diameter of the pump chamber and the reinforcement body further comprises a biocompatible layer lining each of the pump chamber and the first and second fluid pathways, and wherein said reinforcing material comprises metal, metal alloy, ceramic, polymer having carbon-fibers or other fibers therein, or polymeric material, or a combination thereof, and said biocompatible layer comprises polyetheretherketone (PEEK), polyphenylene sulfide (PPS), or polyetherketoneketone (PEKK).

A biocompatible pump head for a pump comprising:

• a reinforcement body for a pump head comprising metal, metal alloy, ceramic, polymer having fibers therein, a polymeric material, or a combination thereof and having first and second apertures therein, each aperture coupled with a fluid pathway therethrough, the fluid pathways extending between the apertures and a chamber in the reinforcement body configured to receive a portion of a pump, wherein each fluid pathway has a diameter that is smaller than a diameter of the chamber and is configured to accommodate flow of a biocompatible material;
• and
• a biocompatible layer lining each of the fluid pathways and the chamber of said reinforcement body.
