Systems, devices, and methods for bodily fluid sample collection

Abstract

Bodily fluid sample collection systems, devices, and method are provided. The device may comprise a first portion comprising at least a sample collection channel configured to draw the fluid sample into the sample collection channel via a first type of motive force. The sample collection device may include a second portion comprising a sample container for receiving the bodily fluid sample collected in the sample collection channel, the sample container operably engagable to be in fluid communication with the collection channel, whereupon when fluid communication is established, the container provides a second motive force different from the first motive force to move a majority of the bodily fluid sample from the channel into the container.

         70 . A method comprising:
 collecting a sample into at least one sample collection channel of a sample collection device via a first type of motive force;   after a desired amount of sample fluid has been confirmed to be in the sample collection channel, establishing fluid communication between the sample collection channel and a sample container of the sample collection device, whereupon the container uses a second motive force different from the first motive force used to collect the sample to move bodily fluid sample from the sample collection channel into the sample container;   wherein the sample container has gas permeable and penetration re-sealable enclosure.   
     
     
         71 . The method of  claim 70 , wherein an interior of one of the sample collection channel is coated with an anticoagulant. 
     
     
         72 . The method of  claim 71 , wherein the anticoagulant is citrate. 
     
     
         73 . The method of  claim 71 , wherein the anticoagulant is heparin. 
     
     
         74 . The method of  claim 71 , wherein the anticoagulant is ethylenediaminetetraacetic acid (EDTA). 
     
     
         75 . The method of  claim 70  wherein the second motive force comprises a suction force. 
     
     
         76 . The method of  claim 70  further comprising mixing the bodily fluid sample with the anticoagulant coating prior to the sample entering the sample container and doing so without having to repeatedly tilt or agitate the sample collection device. 
     
     
         77 . The method of  claim 70  wherein the first type of motive force comprises capillary force. 
     
     
         78 . The method of  claim 70 , wherein the sample collection channel can hold a volume of no greater than 500 μL. 
     
     
         79 . The method of  claim 70 , wherein the collection channel can hold a volume of no greater than 200 μL. 
     
     
         80 . The method of  claim 70 , wherein the sample container has an interior volume no greater than twenty times larger than the interior volume of the collection channel with which it is engagable. 
     
     
         81 . The method of  claim 70 , wherein the sample container has an interior volume no greater than ten times larger than the interior volume of the collection channel with which it is engagable. 
     
     
         82 . The method of  claim 70 , wherein the sample container has an interior volume no greater than five times larger than the interior volume of the collection channel with which it is engagable. 
     
     
         83 . The method of  claim 70 , wherein the sample container has an interior volume no greater than two times larger than the interior volume of the collection channel with which it is engagable. 
     
     
         84 . The method of  claim 70 , wherein establishing fluidic communication between the collection channel and the sample container results in transfer of at least 90% of the bodily fluid sample in the collection channel into the sample container. 
     
     
         85 . The device of any one of  claim 84 , wherein establishing fluidic communication between the collection channel and the sample container results in transfer of the bodily fluid sample into the sample container and in no more than five μL of bodily fluid sample remaining in the collection channel.
