US 8,506,547 B2 · Device and method for transferring fluids within a surgical environment

Abstract

A method and device for transferring fluids from a non-sterile field to a sterile field within a surgical environment includes utilizing a device that includes a main body having a first inlet port that is in communication with a first outlet port. Fluid is taken from the patient, typically with a sterile syringe and transferred to the non-sterile field where the fluid is processed. The processed fluid is then drawn into another syringe in the non-sterile field and a distal end of the first syringe is place within the inlet port of the sterile main body. A distal end of a second sterile syringe is inserted into the outlet port, where the distal ends of the sterile syringe and the non-sterile syringe do not make contact. As a plunger is forced into a chamber of the first non-sterile syringe to force the fluid out of the first syringe, the plunger of the second sterile syringe is retracted such that a chamber in the second syringe has a sufficient volume to store the processed liquid. Since the first non-sterile syringe and the second sterile syringe do not make contact during the transfer of the processed fluid, the sterile field is maintained and the fluid can be utilized in the surgical procedure.

Dependent claims

A device for maintaining the sterility of a sterile field in a surgical environment when transferring liquid from a non-sterile field to the sterile field, the device comprising:

a barrier wall comprising a first surface and a second surface separated from the first surface and a first through bore spaced apart from a second through bore, the first and second through bores extending from the first surface to the second surface;
a first inlet port attached to the first surface of the barrier wall and in fluid communication with the first through bore;
and
a first outlet port attached to a second surface of the barrier wall and in fluid communication with the first inlet port and the first through bore, the first inlet port and the first outlet port both being configured to engage a discharge end of separate first and second syringes,
wherein the discharge ends of the first and second syringes are configured to fluidly communicate respectively with the first inlet port and the first outlet port for transferring liquid from the non-sterile field of the first syringe to the sterile field of the second syringe without contaminating the sterile field.
