Systems and methods for delivering a fluid to a patient with reduced contamination
First Claim
1. A method of delivering a fluid to a patient using a fluid transfer device, the method comprising:
- establishing fluid communication between the patient and the fluid transfer device;
disposing a flow control mechanism in a first configuration to establish fluid communication between the patient and a fluid reservoir;
withdrawing a predetermined volume of a bodily fluid from the patient;
transferring the predetermined volume of the bodily fluid to the fluid reservoir;
fluidically isolating the fluid transfer device from the fluid reservoir to sequester the predetermined volume of the bodily fluid in the fluid reservoir; and
automatically moving the flow control mechanism to a second configuration after the redetermined volume of the bodily fluid has been transferred to the fluid reservoir to establish fluid communication between the patient and a fluid source.

Abstract
An apparatus includes a cannula assembly, a housing, a fluid reservoir, a flow control mechanism, and an actuator. The housing includes an inlet port removably coupled to the cannula assembly and defines an inner volume. The fluid reservoir is fluidically coupled to the housing and configured to receive and isolate a volume of bodily fluid from a patient. The flow control mechanism is at least partially disposed in the inner volume. The actuator is operably coupled to the flow control mechanism and is configured to move the flow control mechanism between a first configuration, in which bodily fluid can flow, via a fluid flow path defined by the flow control mechanism, from the cannula assembly, through the inlet port and into the fluid reservoir, to a second configuration, in which the fluid reservoir is fluidically isolated from the cannula assembly.

6. A method of delivering a fluid to a patient using a fluid transfer device, the method comprising:
-
establishing fluid communication between the patient and a fluid reservoir defined by the fluid transfer device; disposing a flow control mechanism in a first configuration to establish fluid communication between the patient and the fluid reservoir; transferring a predetermined volume of a bodily fluid from the patient to the fluid reservoir; sequestering the predetermined volume of the bodily fluid in the fluid reservoir, whereby the sequestering the predetermined volume of the bodily fluid sequesters microbes present in the predetermined volume of the bodily fluid; automatically moving the flow control mechanism to a second configuration after the predetermined volume of the bodily fluid has been transferred to the fluid reservoir to establish fluid communication between the patient and a fluid source; and transferring fluid from the fluid source to the patient via the fluid transfer device. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method of delivering a fluid to a patient using a fluid transfer device, the fluid transfer device including a flow control mechanism, the method comprising:
-
establishing fluid communication between the patient and the fluid transfer device; disposing the flow control mechanism in a first configuration to define a first fluid flow path, the first fluid flow path placing a fluid reservoir defined by the fluid transfer device in fluid communication with the patient; transferring a predetermined volume of a bodily fluid from the patient to the fluid reservoir; automatically moving the flow control mechanism to a second configuration after the transferring the predetermined volume of the bodily fluid to (1) fluidically isolate the predetermined volume of the bodily fluid in the fluid reservoir and (2) define a second fluid flow path, the second fluid flow path placing a fluid source fluidically coupled to the fluid transfer device in fluid communication with the patient; and transferring fluid from the fluid source to the patient via the second fluid flow path. - View Dependent Claims (13, 14, 15, 16, 17)
