Sampling module device and method
View Patent ↗A tissue penetration device and method of using same that may include a lancet module or sampling module. The sampling module may optionally be in a cartridge configuration and include sampling and analyzing functions, which may be integrated.
1. A sampling module, comprising:
a module body portion that includes a lancet channel;
a lancet with a sharpened distal tip and shaft portion which is slidably disposed within the lancet channel to provide for a lancet to travel in a linear axial movement;
a sterility barrier that is pierceable by the lancet; and
a sample chamber in fluid communication with a sample input port of the module body portion wherein the sample chamber has a volume no greater than 1 microliter.
2. The module of claim 1 , wherein the sample chamber includes a vent.
3. The module of claim 1 , further comprising:
a mechanical stop positioned to provide a soft stop for the lancet.
4. The module of claim 1 , wherein the module body is configured to be coupled to a lancet driver that provides controlled velocity of the lancet as the lancet travels.
5. A sampling module, comprising:
a module body portion configured to be mechanically registered and secured adjacent to a lancet driver;
a lancet with a sharpened distal tip and shaft portion which is slidably disposed within the module body portion;
a sterility barrier that is pierceable by the lancet; and
a sample chamber in fluid communication with a sample input port of the module body portion wherein the sample chamber has a volume no greater than 1 microliter.
6. The module of claim 5 , wherein the sample chamber has a vent.
7. The module of claim 5 , further comprising:
a mechanical stop positioned to provide a soft stop for the lancet.
8. A sampling module, comprising:
a module body portion configured to be mechanically registered and secured adjacent to a lancet driver;
a lancet with a sharpened distal tip and shaft portion which is slidably disposed within the module body portion;
a sterility barrier that is pierceable by the lancet; and
a sample chamber in fluid communication with a sample input port of the module body portion wherein the sample chamber has a volume no greater than 1 microliter; and
wherein a velocity of a lancet is controlled as the lancet travels from the sampling module.
