Abstract
A fluid sampling apparatus is provided that in accordance with the present invention. The apparatus includes a housing defining a chamber, a lancet positioned in the chamber and including an end formed to create a fluid collection incision, and a light source positioned in the chamber. The light source is formed to emit a light beam of a pre-determined wavelength and for a time sufficient to seal the incision.
Claims21
A fluid sampling apparatus comprising:
- a housing defining a chamber having an opening,
- a lancet positioned in the chamber and including an end formed to create a fluid collection incision, and
- a light source positioned in the chamber, the light source fanned to emit a light beam through the opening of the housing into the fluid collection incision, the light beam being of a pre-determined wavelength and for a time sufficient to seal the incision.
A fluid sampling apparatus, the apparatus comprising:
- a housing defining a chamber having an opening,
- a lancet positioned in the chamber and including an end formed to create a fluid collection incision.
- means for collecting blood from the open incision, and
- a light source coupled to the housing, the light source emitting light through the opening of the housing into the incision, the light being of a pre-determined wavelength and for a time sufficient to seal the incision following withdrawal of the blood.
