Pipette tip and pipette system for capillary blood collection

Abstract

The capillary blood pipette tip system of the present invention includes a pipette tip for collecting capillary blood including a sampling unit having a capillary tube having a first diameter so as to sample a capillary blood; a sample storage unit having a first extension end formed from a distal end of the capillary tube of the sampling unit so as to have a larger area than the sampling unit; a sealing unit closely adhered to a distal opening of the sample storage unit and broken by a quantitative syringe introduced from the outside; a shielding wall surrounding the sealing unit to prevent the sample from splashing from the sample storage unit to the outside when the sealing unit is broken by the quantitative syringe; and a handle unit which is held by a user to sample using the sampling unit; an immunoassay cartridge having at least one pipette tip mounting well having a plunger that presses a sample of a sampling unit of the pipette tip from the bottom to the top when the pipette tip is coupled to the top; and a quantitative syringe for quantitatively sampling the capillary blood collected in the upper part thereof by approaching through the upper part of the pipette tip, when the capillary blood from the sampling unit is collected in the upper part by the pressurization of the plunger during the coupling of the pipette tip to the immunoassay cartridge.
