Body-fluid inspection device
First Claim
1. A body-fluid inspection device which sticks a skin so as to obtain a fine amount of body fluids and measures ingredients of the body fluids, comprising:
- a casing having an opening;
sticking means having a sticking needle that is allowed to protrude from the opening of the casing;
suction means which places at least a portion of a space inside the casing in a reduced-pressure state for sucking body fluids from a wound produced by the sticking means;
reduced-pressure releasing means for releasing the space inside the casing from the reduced-pressure state, the reduced-pressure releasing means being provided with a vent hole which allows the inside and the outside of the casing to communicate with each other and an opening and closing means for opening and closing the vent hole;
a chip which is detachably attached to the opening of the casing, and provided with test paper for absorbing the body fluids that have been sucked by the suction means;
measuring means for measuring ingredients of the body fluids that have been absorbed by the test paper; and
display means for displaying results of measurements made by the measuring means, the display means being placed on one portion of a surface of the casing, wherein the sticking means, the suction means and the measuring means are installed inside the casing.

Abstract
A body-fluid inspection device, which sticks a skin so as to obtain a fine amount of body fluids and measures ingredients of the body fluids, includes a casing having an opening, a sticking device having a sticking needle that is allowed to protrude from the opening of the casing, and a suction device which places at least portion of a space inside the casing in a reduced-pressure state. Also included are a reduced-pressure releasing device for releasing the space inside the casing from the reduced-pressure state, a chip which is detachably attached to the opening of the casing and is provided with test paper for absorbing the body fluids that have been sucked by the body-fluid suction device, a measuring device for measuring ingredients of the body fluids that have been absorbed by the test paper, and a display device for displaying results of measurements made by the measuring device. The display device is placed on one portion of a surface of the casing. The sticking, the suction and the measuring devices are installed inside the casing.

a housing having an opening at the tip end thereof;
sticking means including a sticking plunger that is allowed to shift toward the tip end inside the housing with the sticking needle being attached thereto, and a first pressing means for pressing the sticking plunger toward the tip end;
suction means including a suction plunger that is provided with a seal member having an air-sealed property and that brings the housing to a reduced-pressure state upon shifting toward the base end, and a second pressing means for pressing the suction plunger toward the base end;
air-releasing means for releasing the housing which is in a reduced-pressure state to the atmospheric pressure; and
operation means for carrying out at least a sticking process by the sticking needle and a pressure-reducing process inside the housing by an operation of the suction plunger, successively in this order or at the same time.

9. The body-fluid inspection device according to claim 1, which comprises:
-
a housing having an opening at the tip end thereof;
sticking means including a sticking plunger that is allowed to shift toward the tip end inside the housing with the sticking needle being attached thereto, and a first pressing means for pressing the sticking plunger toward the tip end;
suction means including a suction plunger that is provided with a seal member having an air-sealed property and that brings the housing to a reduced-pressure state upon shifting toward the base end, and a second pressing means for pressing the suction plunger toward the base end;

10. The body-fluid inspection device according to claim 1, which comprises:
-
a housing having a tip end that is opened;
a plunger to which a lancet having a sticking needle extending toward the tip end is attached, the plunger being allowed to slide inside the housing;
a stopper connected in the rear end direction of the plunger;
an adjustment mechanism which contacts the stopper; and
a sticking-use spring for shifting the lancet, the plunger and the stopper toward the tip end of the housing, the sticking-use spring being connected to the plunger or the stopper, wherein;
an engaging section is provided in the inner face of the housing;
a stopping section is formed in at least one of the lancet, the plunger and the stopper, the stopping section being allowed to engage the engaging section so as to stop the lancet, the plunger and the stopper at a first position; and
after the lancet, the plunger and the stopper have shifted toward the tip end from the first position by the spring that is released from the engagement between the engaging section and the stopping section, the stopper comes into contact with the adjustment mechanism so that the shift of the lancet, the plunger and the stopper is stopped at a second position.
