The present invention relates to a painless blood collection device using a laser and a blood glucose measurement device using the same, and relates to a new technology in the field of blood glucose measurement in which blood glucose measurement is performed together with blood collection. More specifically, it is a device for collecting blood without pain from the skin by using the Er: VA laser technology in the medical field. The individual uses a laser having a wavelength of 2.94 μm that has a strong absorption ability against water and has little harm to the human body. The present invention relates to a portable painless blood collection device and a blood glucose measurement device using the same.

Generally used for painless blood collection, the Er: laser laser generator (laser head) is a reflector made by depositing or plating silver / nickel / copper or these alloys several times on the surface of a metal body and then processing the surface. The parts are formed in an outer shape, and the reflector has a flash pump for laser pumping and an Er: VA crystal, respectively. The laser intensity emitted from the Er: VA laser generator varies depending on the amount of light emitted from the flash lamp and the volume, size, and density of the Er: VA crystal.

However, the conventional painless blood collection device using a laser has poor adhesion between the Er: BAA laser generating device and the skin, and when a hole is punched through the skin, a "puck" sound is heard and white spots on the skin where the blood is collected There is a disadvantage that the smoke coming out and burning the skin anxious the psychology of blood patients. In addition, since the flash of the flash lamp and the laser irradiated to the skin are visible, the retina may be damaged by strong stimulation.

Insulin-dependent patients who need to measure blood glucose in real time 2 to 3 times a day usually have a needle-like lancet in the form of a blood sample, which is painful because blood is cut by cutting the skin tissue with a lancet. Not only is this large, it also results in the blood being drawn more than necessary. In addition, the bleeding area must be bleeding, and even after such bleeding, the wound may not heal quickly and may be infected by a virus or bacteria.

In addition, an infrared scanning blood glucose measurement apparatus that measures blood glucose indirectly has been recently introduced, but the reliability of the measurement value is lower than that of the direct blood collection method, which is not used well.

Meanwhile, in the related art, blood collection devices and blood glucose measurement devices are manufactured and supplied separately, so that blood sugar can be measured only when all of these equipments are provided, resulting in inconvenience in purchasing and storing the equipment.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of a very small amount painless blood collection device using the Er: VA laser according to an embodiment of the present invention and a blood glucose measurement device using the same.

One. Er: very small amount of bloodless device using BAA laser

Figures 1 to 4 is a model showing a laser-painless blood collection device and one of the main components of the adapter and the disposable skin adhesion cap according to a preferred embodiment of the present invention.

As shown in Fig. 1, the Er: VA laser generating unit of this embodiment is inserted into a reflector 2 having an accommodating space therein and an accommodating space of the reflector 2, with both ends exposed to the outside of the accommodating space. Flash lamps interpolated in the receiving space of the reflector at a distance from the Er: BAx crystal 9, the mirrors 7 and 11 fixed to both ends of the Er: BAx crystal 9, and the Er: BAx crystal 9; (flash Lamp) (3). Both ends of the Er: BAA crystal and the flash lamp are supported by the front fixing cover 1 and the rear fixing cover 4 provided on both the front and rear ends of the reflector so as not to move, and the front and rear fixing covers and the reflector are integrated. The front and rear fixing holders 8 and 10 are respectively inserted to the outside of both the front and rear ends of the reflector for the purpose of fixed fixing.

Here, among the mirrors, the semi-transmissive mirror 7 is attached to the front surface of the Er: VA crystal, and the total reflection mirror 11 is attached to the rear surface.

The Er: VA crystal (9) induces and condenses the flash emitted from the flash lamp (3) and has a wavelength of 2.94 µm of a wavelength of 0.1 to 0.6 mJ due to the Lasing transition 4I11 / 2 → 4I13 / 2 of the crystal. As a component that is generated by a laser having strong hydrophilicity, the intensity of the laser is determined by the crystal structure and density of the crystal, the volume, and the amount of light emitted by the flash lamp.

In this embodiment, the fine Yttrium Aluminum Garnet (Y ₃ A _{l 5} O ₁₂ ⁺³ ) powder is formed by melting at 1870 ° C Melting Point and OH-free Special Coating so that the laser is evenly irradiated in a constant direction and its intensity is kept high. After surface treatment, the surface roughness was precisely processed to 1 μm or less.

Here, since the crystals of the Er: VA crystals 9 must be kept in a clear and transparent state without any impurities in the crystal structure, the dopant takes a very long time, and must be precisely cut and polished to 1 μm or less. Since the linearity of the beam is maintained and interference scattering is eliminated, a know-how by skilled technical personnel is required.

The flash lamp 3 for laser pumping is a device for generating a flash of about 80 to 100 WS to supply energy to the Er: VA crystal 9. In the present embodiment, the flash lamp 3 is used in a vacuum cylindrical bar glass tube. After charging the xenon gas of 700mmHg (xenon gas), a high voltage was applied to both electrodes installed at intervals of about 40 ~ 45mm, and a flash voltage of 80-100WS level was induced using a trigger voltage.

The reflector in which the Er: BAA crystal 9 and the flash lamp 3 are provided at regular intervals is an element that forms the appearance of the Er: BAA laser generating unit. The flash emitted from the flash lamp 3 is reflected from the inner surface of the reflector. By reflecting at least%, it serves to guide and focus the Er: BAX crystal 9.

In the present embodiment, when the reflector is manufactured, silver is first deposited on the surface of quartz glass to maintain a reflectivity of 98% or more, and the surface is coated with nickel and copper alloys to prevent oxidation of silver (Ag). Was milled.

Reference numerals 7 and 11 are marked with the mirror Er: as a component of the focused laser by a YAG crystal (9) is irradiated while keeping the linearity in a predetermined direction, of 10 ^-9 m, depending on the laser irradiation angle and direction The surface was precisely polished to maintain flatness, and the surface was polished and smoothed.

In addition, the transflective mirror 7 mounted in the direction in which the laser is irradiated (front end) is processed so that the transmittance can be maintained at 50% or more, and the total reflection mirror 11 mounted on the opposite side (rear) is an Er: VA crystal. More than 90% of the laser focused on the laser beam was processed so that it could be reflected in the direction to be irradiated.

This is a further development of the conventional Er: VA laser technology. The total reflection / transflective mirrors 7 and 11 are directly connected to both ends of the Er: VA crystal, and then coated to reduce the laser loss caused by interference and scattering. This resulted in minimal transmission and improved laser linearity.

1 and 2, the adapter of the present embodiment is mounted in front of the total reflection mirror 7 of the Er: VA laser generation unit described above.

Further, a focusing lens holder 6, a focusing lens 5 inserted into an inner passage of the focusing lens holder, a connector 14 fitted to an outer surface of the focusing lens holder, and a buffer spring 15 interposed therebetween. Consists of.

The focusing lens 5 is a component that focuses a laser beam irradiated in a predetermined direction on the blood-collected skin with an accurate focus, and can drill a 0.1-0.5 mm diameter hole in the skin to a depth of 0.2-4 mm. However, the skin penetration depth was 0.5 mm or less and 0.3 mm in diameter so as not to cause pain by stimulating nerve cells in the dermal tissue. In order to maintain such skin penetration depth and perforation diameter, the distance from the total reflection mirror 7 in the direction of laser irradiation to the focusing lens was maintained at 13 mm to 15 mm, and the distance from the focusing lens to the skin surface was 17.5 mm in use. It adjusted so that it might become about -18.0 mm.

In this way, the blood flow of capillaries existing between epidermal and dermal tissues can be stimulated up to 400 μsec to 500 μsec to easily collect 0.5 μl or more of blood required for blood glucose measurement and minimize wound size and pain. have.

The amount of blood collected can be adjusted according to the energy intensity of the laser from 1 μl to 500 μl, and it has the effect of preventing the occurrence of burning smell and dull sound of the skin during the first blood collection. In addition, the surface of the focusing lens 5 was precisely processed and then polished to 10 ^-9 m to minimize energy loss due to interference and scattering and to increase efficiency.

The above-described embodiment of the adapter serves to block / absorb the noise generated when the flash and the blood generated from the flash lamp, which is a fundamental problem of the prior art.

That is, the adapter according to the present invention can be regarded as a kind of "sealed explosion proof" adapter.

In addition, the connector 14 inserted into the front end of the focusing lens holder with the focusing lens is made of a compression polyester material to increase the noise blocking effect through airtightness.

In addition, the surroundings are sealed by a heat shrink tube made of foam compression type engineering plastic to block the final noise and the flash from the flash lamp 3.

The skin close cap (see FIGS. 3 and 4) indicated by reference numeral 13 is configured to be easily inserted into the connector 14 of the front end of the adapter when pressed with a finger.

The skin adhesion cap is made of an elastic soft material (for example, Silicon Rubber) to maintain airtightness while keeping contact with the skin slightly compressed in contact with the skin in order to eliminate the pain caused by the collection and ease of blood collection. It is preferable.

In addition, the skin-contacting cap of this embodiment has a thin polyethylene verification film 12 attached to a cylindrical rear end inserted into the connector 14 of the adapter to face the focusing lens. Blood can be prevented from falling into the focusing lens when the hole is punctured, thereby decreasing the linearity and transmittance of the laser, and preventing the blood collected from being contaminated. In addition, since the polyethylene film is punctured by a laser at the time of laser irradiation (that is, at least once), it can be easily checked whether it is reused. In addition, a support jaw 16 protruding from the body outer surface of the skin close cap to prevent shaking during blood collection.

In addition, the ultra-low amount painless blood collection device using the Er: VA laser of this embodiment includes two safety devices.

One of them is an interlock sensor (not shown) which is kept in a locked state if the skin cap 13 is not completely fixed to the connector 14 of the adapter, and is provided at the connector. According to this, the interlock sensor is operated to irradiate the laser only when the finger is pressed in the state of being in close contact with the skin-adhesive cap and completely fixed to the connection port.

5, the interlock sensor (not shown) is fixed to the interlock switch fixing holder 33 located inside the case 32, and the stopper type interlock switch operating knob 31 located outside the case. ) So that the laser is irradiated. In other words, these safety devices serve to prevent the laser from irradiating to human parts other than the finger.

8 is a model diagram showing a blood glucose measurement apparatus according to an embodiment of the present invention.

As shown in the drawing, in this embodiment, the total reflection / transflective mirrors 7 and 11 are respectively mounted on both ends of the Er: VA crystal 9 so that they can be used at any time regardless of the location and are easy to carry. The laser control circuit 28, which is composed of 21) and ultra-compact charging / trigger transformers 22 and 27, was implemented and manufactured as a PCB to reduce the size and weight of the device.

In addition, by adopting a power supply device 29 using a lithium-ion battery, blood collection and blood glucose measurement can be performed more than 50 times without supplying AC power. The peripheral circuit 30 including the microprocessor unit (MPU) has a small PCB. Was implemented.

The laser control circuit 28 implemented as a PCB charges a voltage applied from a transformer to a capacitor and controls the amount of electricity supplied through the control circuit, thereby minimizing the intensity of the Er: VA laser by controlling the amount of emitted light of the flash lamp to 80 to 100 WS. Adjust from 0.1J up to 0.6J.

In addition, the safety device for preventing the laser irradiation to other than the blood collection site can be used only for blood collection and blood glucose measurement of the finger in conjunction with the [READY] display of the laser control circuit 28 and the input and output device 26 including the LCD. It was made.

The connector 25 is a component for inserting the blood sugar sensor strip 24 in which the blood sugar information is embedded, and the blood sugar information of the blood sugar sensor strip is transmitted to the blood sugar measuring circuit 23 implemented as a PCB, and is displayed through the LCD. And the measured blood glucose level is stored.

Here, the blood glucose sensor strip is a strip that collects about 0.5 μl of blood collected by an Er: VA laser method and provides blood glucose information according to an electrical chemical reaction. The blood insert absorbs the collected blood. And an insert sensor for determining whether blood glucose information can be collected by the absorbed blood, and a contact connector for reacting the collected blood glucose information with a reagent dispensed on a strip and transmitting the blood glucose information to the blood glucose measurement circuit 23 by an electrical chemical analysis method. The apparatus was configured at 25.

Thus, a small amount of blood can accurately measure blood glucose.

For this control / measurement, the present embodiment configures 32-bit MPU and peripheral circuits on the PCB and embeds the operating software to simplify / miniaturize the configuration circuits and to eliminate various faults and malfunctions that may occur due to complicated circuit configurations. Factors of occurrence and occurrence of measurement errors were prevented in advance.

[Modification example]

On the other hand, the blood glucose measurement apparatus of the present invention, in addition to the component, the amount of electricity supplied to the flash lamp according to the characteristics of the person collecting blood from the minimum (400 V) voltage applied to the anode (Anode) and the cathode (Cathode) to a maximum 700V voltage By adjusting, there is a control button to change the intensity of laser from 8 steps to 16 steps.

In addition, a predetermined program for displaying a blood sugar value, a residual electric charge of a rechargeable battery, and a date and time for measuring laser blood collection and blood sugar, etc., is displayed on the LCD screen in numerical values or symbols.

As described above, the present invention is about 0.5 μl of blood without blood collection and then used for blood glucose measurement, it can see a great effect when spread to insulin-dependent patients (diabetic patients).

In addition, the laser is irradiated to sterilize by heating the skin to about 1000 ℃ or more instantaneously, it is possible to prevent infection due to viruses or bacteria without separately disinfecting the blood collection site.

In addition, by placing the adapter and the skin-adhesive cap excellent in adhesion to the skin at the tip of the Er: VA laser generating unit, there is an effect of primarily removing the burning odor, smoke and dull noise of the skin.
