BODY FLUID SAMPLING DEVICE AND BODY FLUID MEASURING DEVICE USING THE SAME
First Claim
1. A body fluid sampling device comprising:
- a connecting portion to which a body fluid container is connected;
a suctioning portion which suctions a gas in the body fluid container connected to said connecting portion, to introduce a body fluid into the body fluid container;
a suctioning passage which causes an inside of said suctioning portion and an inside of the body fluid container connected to said connecting portion, to be communicated with each other;
a first electrode which is disposed to extend across said suctioning passage and has gas permeability;
a second electrode which is disposed to extend across said suctioning passage and be opposed to said first electrode, and has gas permeability; and
a detector which detects an electric signal generated between said first electrode and said second electrode.

Abstract
A body fluid sampling device (100) includes: a connecting portion (105) to which a body fluid container is connected; a suctioning portion (117) which suctions a gas in the body fluid container connected to the connecting portion, to introduce a body fluid into the body fluid container; a suctioning passage (105a) which causes an inside of the suctioning portion and an inside of the body fluid container connected to the connecting portion, to be communicated with each other; a first electrode (112) which is disposed to extend across the suctioning passage and has gas permeability; a second electrode (113) which is disposed to extend across the suctioning passage and be opposed to the first electrode, and has gas permeability; and a detector which detects an electric signal generated between the first electrode and the second electrode. With this, the present invention provides the body fluid sampling device capable of detecting improper suctioning of the body fluid, and a body fluid measuring device using the body fluid sampling device.
