Accelerated ergonomic collection of capillary blood

An apparatus comprising:

• a plasma separator module comprising:
• a blood input port that at least partially defines an upstream separator flow path and is configured to couple to a transfer port of a blood collector module;
• a plasma output port that at least partially defines a downstream separator flow path and is configured to transfer plasma to a sample tube with a predetermined outside diameter when the sample tube is coupled to the plasma output port;
• a separator body portion that links the blood input port and the plasma output port, the separator body portion channels blood from the upstream separator flow path to an upstream entry surface of one or more multilayer plasma separation units, wherein the separator body portion further comprises the downstream separator flow path that fluidically couples a downstream exit surface of the one or more multilayer plasma separation units to the plasma output port,
• wherein when the blood input port of the plasma separator module is coupled to the blood collector module and the sample tube is coupled to the plasma output port:
• an actuation of the blood collector module begins a collection of plasma by causing blood to flow from a collection site on skin of a subject through the upstream separator flow path to the upstream entry surface of a plasma separation membrane of each of the one or more multilayer plasma separation units;
• and
• the collection of the plasma is completed by the plasma separation module using the one or more multilayer plasma separation units to perform plasma separation on the blood collected by the blood collector module and outputting separated plasma to the sample tube when the blood collector module is decoupled from the collection site.

An apparatus for a blood collection device to comprising:

• a lancet strip assembly comprising a plurality of linearly-arranged lancet strips, each linearly-arranged lancet strip including from 3 to 10 evenly distributed flat lancets aligned to configured to produce multiple rows of blood extraction slits in a collection site in skin of a subject;
• and
• one or more channels between the plurality of linearly-arranged lancet strips,
• wherein in response to actuation, a lancet carrier propels the plurality of linearly-arranged lancet strips towards the collection site to produce the multiple rows of blood extraction slits in the skin of the subject.

A method comprising:

• firing one or more lancets to produce one or more blood extraction slits in response to a lengthwise sliding motion of a slide latch on a blood collector module sealingly coupled to a collection site on a body part of a subject;
• distributing a first negative pressure to facilitate a flow of blood from the collection site to an upstream entry surface of one or more multilayer plasma separation units of a plasma separator module;
• and
• in response to a collection opening of the blood collector module being exposed to a current local atmospheric pressure (P0) after a decoupling of the blood collector module from the collection site, regulating a downstream separator flow path of the plasma separator module to a second negative pressure that is closer to P0 than the first negative pressure to limit force exerted on blood as it is separated by passing through the one or more multilayer plasma separation units.
