Vacuum tube receiver for drawing blood through a peripheral IV catheter

A vacuum tube receiver comprising:

• a housing having a proximal end and a distal end and forming a hollow interior, the proximal end forming a proximal opening for receiving a vacuum tube into the hollow interior, the distal end forming an adapter for coupling the vacuum tube receiver to an intravenous system;
• a spike that extends proximally into the hollow interior, the spike including an opening and forming a blood flow path;
• an insertion depth control component that includes a stop member, the insertion depth control component being coupled to the housing and being configured to move the stop member between a withdrawn position outside of the hollow interior and an inserted position inside of the hollow interior, wherein, with the insertion depth control component in the inserted position, the stop member is configured to limit insertion of the vacuum tube into the hollow interior;
• and
• a flow control component having a shaft that inserts into a distal end of the spike and a head that is positioned overtop the distal end of the spike, the head forming channels through which blood flows to enter the spike.

• wherein the vacuum tube has a septum forming a vacuum seal at a distal end of the vacuum tube and one or more additional septums that are proximally spaced from the septum, each additional septum forming a vacuum seal within the vacuum tube;
• and
• wherein a length of the spike is sufficient to pass through the septum and each of the one or more additional septums when the vacuum tube is inserted into the hollow interior of the housing.

A vacuum tube receiver comprising:

• a housing having a proximal end and a distal end and forming a hollow interior, the proximal end forming a proximal opening for receiving a vacuum tube into the hollow interior, the distal end forming an adapter for coupling the vacuum tube receiver to a peripheral IV catheter or to another IV system;
• a first spike that extends proximally a first distance into the hollow interior forming a first blood flow path;
• and
• a second spike that extends proximally a second distance into the hollow interior, the first distance being greater than the second distance, the second spike alse forming a second blood flow path, wherein the first spike has an inside diameter that is smaller than an inside diameter of the second spike.

A vacuum tube receiver comprising:

• a housing having a proximal end and a distal end and forming a hollow interior, the proximal end forming a proximal opening for receiving a single vacuum tube into the hollow interior, the distal end forming an adapter for coupling the vacuum tube receiver to an intravenous system;
• and
• a first spike that extends proximally into the hollow interior, the first spike forming a first blood flow path;
• and
• a second spike that extends proximally into the hollow interior, the second spike forming a second blood flow path,
• wherein each of the first spike and the second spike is configured to pierce a septum of the single vacuum tube and wherein the first spike and the second spike are connected by a channel extending between the first spike and the second spike;
• and
• a stopper located in the channel, the stopper configured to move from an initial position in which the stopper blocks the second blood flow path to a subsequent position in which the stopper does not block the second blood flow path.
