a needle formed through the housing and into the blood collection port; and a baffle formed within the baffle chamber to counteract a vacuum within a blood collection tube when pierced by the needle. ## Claims ### Claim 1 A blood sample collection system, comprising: a housing, the housing comprising: a blood collection port; and a baffle chamber; a collection needle formed through the housing and into the blood collection port; a baffle formed within the baffle chamber to counteract a vacuum within a blood collection tube when pierced by the needle; and a spring disposed within the baffle and biased such that the baffle is in an expanded state. ### Claim 2 (depends on 1) The blood sample collection system of claim 1, further comprising a baffle needle formed through the housing and fluidically coupling the baffle with an interior of the blood collection tube. ### Claim 3 (depends on 2) The blood sample collection system of claim 2, further comprising a baffle conduit formed in the housing to fluidically couple the baffle to the baffle needle. ### Claim 4 (depends on 3) The blood sample collection system of claim 3, further comprising a filter formed in the baffle conduit to prevent blood from entering the baffle. ### Claim 5 (depends on 1) The blood sample collection system of claim 1, wherein the blood collection port comprises a thread to receive a complimentary thread formed on a blood collection tube. ### Claim 6 (depends on 1) The blood sample collection system of claim 1, further comprising a hub connector fluidically coupled to the needle to fluidically couple the blood sample collection system to an intravenous device. ### Claim 7 (depends on 1) The blood sample collection system of claim 1, wherein the baffle has an internal volume of 5 ml. ### Claim 8 (depends on 1) The blood sample collection system of claim 1, further comprising the blood collection tube, wherein the blood collection tube includes a thread to engage a surface within the blood collection port. ### Claim 9 (depends on 1) The blood sample collection system of claim 1, further comprising a compressed saline flush tube to be received at the blood collection port and replace the blood collection tube subsequent to a blood collection process. ### Claim 10 (depends on 9) The blood sample collection system of claim 9, wherein the compressed saline flush tube comprises a locking thread that, once introduced into the blood collection port, locks the compressed saline flush tube into the blood collection port to prevent removal of the compressed saline flush tube. ### Claim 11 A peripheral intravenous catheter (PIVC) device, comprising: a housing, the housing comprising: a blood collection port, the blood collection port comprising a thread to receive a complementary thread from a blood collection tube placed in the blood collection port; and a baffle chamber fluidically coupled to the blood collection port via a baffle conduit formed into the housing; a needle formed through the housing and into the blood collection port; a baffle formed within the baffle chamber to counteract a vacuum within a blood collection tube when pierced by the needle; and a spring disposed within the baffle and biased such that the baffle is in an expanded state. ### Claim 12 (depends on 11) The PIVC device of claim 11, further comprising a baffle needle formed through the housing and fluidically coupling the baffle with the interior of the blood collection tube via the baffle conduit.
