Abstract

A one touch laser lancing type blood glucose measurement device, a strip, and the method using it. In particular, the invention relates to a one touch laser lancing type blood glucose measurement device, a strip, and the method using it, which performs blood gathering and blood glucose measurement at the same time, using laser beams generated in a laser module. The laser beams are irradiated into a finger passing a hole of a strip with a focusing lens converging the laser beams, a protect window, and the hole to gather blood, then the blood is absorbed into the strip for measuring blood glucose.

Claims

1. A one touch laser lancing type blood glucose measurement device comprising:

a laser module generating laser beams and irradiating the laser beams in one direction;

a focusing lens converging the laser beams generated from the laser module and disposed in a laser irradiation direction;

a protect window disposed in a laser direction progressing through the focusing lens and protecting the focusing lens from foreign bodies;

a controlling unit disposed on a position close to a lateral side of the laser module and controlling a blood measure and the laser beams;

a strip connector connected to the controlling unit and formed in a position on which a strip hole and the protect window are coincided with each other, and inserting a strip;

a body unit containing the laser module, the focusing lens, the protect window, the controlling unit, and the strip connector;

a interlock disposed on the outside of the body unit, positioned on the upper or lower side of the strip inserted into the strip connector, forming a hole, and changing the laser module by pressing with a finger into a ready state; and

a button unit formed on a lateral side different from or an opposite side to the interlock holder and operating the laser module.

2. The device of claim 1, further comprising a finger interlock formed on the outside of the body unit, preventing the laser beams irradiated from the laser module from being exposed to the exterior, and having a shape, which a finger is inserted into and a first sensor making a user sense the finger interlock'"'"'s existence.

3. The device of claim 1, further comprising a second sensing unit pressing the interlock holder to sense the ready state of the laser module.

4. A strip used in a blood glucose measurement device, the strip comprising:

a reagent unit;

an electrode unit inserted into strip connector to transfer blood information to the blood glucose measurement device;

a strip hole passing laser beams irradiated from the laser module to irradiate the laser beams; and

a polypropylene film included on the upper of the strip hole to prevent the blood glucose measurement device from becoming polluted.

5. The strip of claim 4, in which the reagent unit measures a glucose from among the group consisting of a ferment, anti-insulin, and HbAIc.

6. A blood glucose measurement method comprising:

a first process of inserting a strip into a strip connector;

a second process of inserting a finger into an upper of an interlock holder and into the inner of the finger lock holder;

a third process of changing into a ready state by pressing the interlock holder;

a fourth process of operating a laser module using a button module to generate laser beams, after the change into the ready state;

a fifth process of converging the generated laser beams into a focusing lens, passing a protect window, a strip hole, and an interlock holder, and then irradiating the laser beams into the inserted finger;

a sixth process of causing blood oozed from the finger due to the irradiating laser beams to be absorbed into the strip;

a seventh process of transmitting data regarding the absorbed blood to a controlling unit; and

an eighth process of outputting analyzed data regarding the absorbed blood from the controlling unit to a displaying unit.
