Apparatus and methods for disinfection of a specimen container
First Claim
1. An apparatus, comprising:
- a transfer adapter including a proximal end portion and a distal end portion and defining an inner volume therebetween, the distal end portion including a port configured to be fluidically coupled to a diversion device in fluid communication with a bodily-fluid of a patient and configured to divert a first volume of bodily-fluid containing contaminants, the transfer adapter configured to receive a second volume of bodily-fluid from the diversion device, the diversion device configured to prevent the second volume of bodily-fluid from flowing to the transfer adapter prior to diverting the first volume of bodily-fluid such that the second volume of bodily-fluid is substantially free of contaminants;
a fluid reservoir including a contact surface and configured to be inserted though the proximal end portion of the transfer adapter such that at least a portion of the fluid reservoir is movably disposed within the inner volume from a first position to a second position;
a disinfection member configured to couple to the transfer adapter and to establish contact with the contact surface of the fluid reservoir to disinfect the contact surface when the fluid reservoir is in the first position; and
a puncture member disposed within the inner volume of the transfer adapter and fluidically coupled to the port, the puncture member configured to couple with the contact surface of the fluid reservoir to establish fluid communication with the fluid reservoir after the disinfection member disinfects the contact surface and after the fluid reservoir is moved from the first position toward the second position,whereby diverting the first volume of bodily-fluid and disinfecting the contact surface collectively reduce contamination that can result in false results in culture tests of the second volume of bodily-fluid.

Abstract
An apparatus includes a transfer adapter, a puncture member, a disinfection member, and a fluid reservoir. The transfer adapter has a proximal end portion and a distal end portion, and defines an inner volume configured to receive the puncture member. The transfer adapter is coupled to the disinfection member. The distal end portion of the transfer adapter includes a port fluidically coupled to the puncture member and configured to be placed in fluid communication with a bodily-fluid of a patient. The proximal end portion is configured to receive a portion of the fluid reservoir to allow the fluid reservoir to be moved within the inner volume between a first position, in which a surface of the fluid reservoir is placed in contact with the disinfection member, and a second position, in which the puncture member punctures the surface to place the puncture member in fluid communication with the fluid reservoir.

13. A method, comprising:
-
establishing fluid communication between a patient and a transfer adapter via a diversion device, the transfer adapter defining an inner volume that houses a puncture member and a disinfection member, the puncture member configured to receive a sample volume of bodily-fluid from the diversion device, the diversion device configured to prevent a transfer of the sample volume of bodily-fluid prior to withdrawing and sequestering a pre-sample volume of bodily-fluid, the pre-sample volume of bodily-fluid containing contaminants and the sample volume of bodily-fluid being substantially free of contaminants; inserting a portion of a fluid reservoir into the inner volume of the transfer adapter; moving the fluid reservoir to a first position in the inner volume to place a contact surface of the fluid reservoir in contact with the disinfection member to at least partially disinfect the contact surface; and moving the fluid reservoir to a second position, after the disinfection member disinfects the contact surface, such that the puncture member punctures the contact surface of the fluid reservoir to allow the sample volume of bodily-fluid to flow into the fluid reservoir, whereby diverting the pre-sample volume of bodily-fluid and disinfecting the contact surface collectively reduce contamination that can result in false results in culture tests of the sample volume of bodily-fluid. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
