Painless blood sampling device using Er:YAG laser generating device and blood sugar measuring instrument using the same

Abstract

The present invention relates to a personal portable painless lancing device and a blood glucose meter using the same, which can lance at the minimum without any pain and use it to measure the blood glucose. The minimum painless lancing device using an Er:AG laser suggested by the present invention, comprises an Er:YAG laser beam-generating section in which the laser beam is generated to punch skin and radiated in a single direction; an adapter installed at the front end of the Er:YAG laser beam- generating section so that the laser beam can be locally concentrated on a skin punch portion; a skin adhesion cap installed at the front end of the adapter so that it can be easily detached, and can reduce the contamination of the Er:YAG laser beam-generating section, which is produced at the time of the lancing, and the danger due to the reuse of it among the patients of lancing; and a case for accommodating the Er:YAG laser beam-generating section and the adapter therein. In this regard, the blood glucose meter suggested by the present invention comprises a minimum painless lancing device with the structure as described above, a connector for inserting a blood glucose sensor strip, a blood glucose measuring circuit, and means for displaying the measure blood glucose value.

Description

technical field [0001] The present invention relates to a painless blood collection device using laser and a blood sugar measuring instrument using the same, and relates to a new technology in the field of blood sugar measurement that performs blood sugar measurement together with blood collection in a single device. More specifically, it relates to a personal portable painless blood collection device for collecting blood without causing pain from the skin by utilizing Er:YAG laser technology in the medical field and a blood glucose measuring instrument using it. It is a laser with a wavelength of 2.94 μm that has strong absorption and is almost harmless to the human body. Background technique [0002] Generally, the Er:YAG laser generating device (laser head) used for painless blood collection is manufactured by processing the surface of the metal body after repeated evaporation or electroplating of silver / nickel / copper or their alloys, so-called reflective plates. The par...

Problems solved by technology

[0003] But, utilize the existing painless blood collection device of laser to have following shortcoming: because the tightness between Er:YAG laser generating device and skin is bad, so can hear the sound of " whooping " when perforating on skin with laser, and Disturbance of the phlebotomy patient by producing white spots and burning smoke on the skin where the blood collection is completed

[0006] In the case of insulin-dependent patients who need to measure blood sugar in real time 2 to 3 times a day, most of them use a needle-shaped lancet to puncture the fingertip part of the finger to collect blood. The skin tissue takes blood, so it is very painful, and it results in the collection of a large amount of blood that requires more

In addition, the bleeding site must be stopped, but after this bleeding, the wound site cannot heal quickly, so there is a possibility of infection due to viruses or bacteria

[0007] In addition, recently, a blood glucose meter with an infrared scanning method that indirectly measures blood sugar has appeared, but compared with the method of direct blood collection, the reliability of the measured value is lower, so it is not often used.

[0008] On the other hand, in the past, a blood collection device and a blood glucose meter were manufactured and provided separately, so all these devices were required to measure blood sugar, and it was inconvenient to purchase and store the devices
