Hereinafter, a laser blood collection device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 1, the laser blood sampling device 10 includes a blood sampling unit 13 including a power supply unit 11, a control unit 12, a voltage charging unit 131, a laser generator unit 132, and a motor unit 133. , a blood sugar signal measurement unit 14, a body temperature measurement unit 15, an operation control unit 16, and a storage unit 17 may be provided.

The power supply unit 11 is a part that supplies power necessary for the operation of the laser blood collection device 10, and a disposable power source or a charging power source can be used.

The manipulation unit 12 may include a manipulation switch for manipulating the laser blood sampling device 10 .

The operation switch may include a power switch, a charge and level switch, a laser irradiation switch, a blood glucose measurement switch for measuring blood sugar, and a body temperature measurement switch for measuring body temperature.

The power switch is a switch for supplying power necessary for the operation of the laser blood collection device 10,

The charge and level switch may be a switch for starting a voltage charging operation for laser irradiation and adjusting a voltage charge level. In this example, the range of the charge level of the voltage may be 250V to 350V, and the level may increase by one step each time the corresponding switch is operated. At this time, the size of the charging voltage at each level may be already determined. For example, the first level may be set to the fifth level, the first level may be 250V, the second level may be 275V, the third level may be 300V, the fourth level may be 325V, and the fifth level may be 350V.

The laser irradiation switch may be a manipulation switch for operating the laser generator 132 .

The blood glucose measurement switch operates the laser generator 132 so that the laser can be irradiated.

The body temperature measurement switch may be operated when the body temperature is to be measured.

The blood sampling unit 13 is configured to perform a blood sampling operation by generating bleeding in a body part of a subject for blood glucose measurement, etc., and in this example, irradiation of a laser beam may be used.

Therefore, as described above, the blood collection unit 13 includes the voltage charging unit 131 for charging the voltage necessary for irradiation of the laser beam, the laser generator 132 for irradiation of the laser beam, and the laser beam to the corresponding body part. A motor unit 133 may be provided to prevent contamination of the blood sampling unit 13 due to soot generated during irradiation.

The voltage charging unit 131 may be connected to the operation control unit 16 .

Accordingly, the operation control unit 16 outputs a charging signal to the voltage charging unit 131 when the charging and level switches are operated so that the charging operation of the voltage charging unit 131 can be performed.

In this example, the voltage charging unit 131 includes a capacitor, and may perform voltage charging required for laser generation using power supplied from the power supply unit 11 . At this time, the magnitude of the voltage to be charged may be determined according to the level selected by charging and manipulating the level switch as described above.

When the voltage charging operation of the voltage charging unit 131 is performed by the operation of the voltage charging unit 131, the charging voltage of the voltage charging unit 131 is applied to the operation control unit 16 as a charging voltage feedback signal to the operation control unit 16. It can be.

Accordingly, the operation control unit 16 may determine whether charging is completed by a voltage corresponding to a level selected for charging and operation of the level switch using the charging voltage feedback signal applied from the voltage charging unit 131 .

When charging to the voltage corresponding to the selected level (eg, 300V) is completed, the operation control unit 16 blocks the charging signal applied to the voltage charging unit 131 so that voltage charging can be performed by a predetermined level.

The laser generating unit 132 may be connected to the voltage charging unit 131 and the operation control unit 16 .

Therefore, when a laser irradiation signal is applied from the operation control unit 16 according to the operation of the laser irradiation switch, a laser beam is generated using the charging voltage applied from the voltage charging unit 131 to be measured, that is, a person who wants to test blood sugar. The corresponding body part (e.g. finger) of the body can be irradiated.

At this time, the intensity of the laser beam irradiated from the laser generating unit 132 may vary according to the magnitude of the charging voltage (eg, 250V to 350V) of the voltage charging unit 131 .

The motor unit 133 may include a motor, and may be connected to the operation control unit 16 and rotated by a driving signal applied from the operation control unit 16 .

At this time, the driving time of the motor unit 133 may be from a set time before the laser beam is output from the laser generator 132 to a set time after the output of the laser beam is completed. Accordingly, the irradiation operation of the laser beam may be performed while the motor unit 133 rotates, and the driving time of the motor unit 133 may be longer than the irradiation time of the laser beam.

In this example, the driving time of the motor unit 133 may be 3 seconds to 5 seconds.

Referring to FIGS. 3 and 4 , the structure of the blood sampling unit 13 in which blood is collected by a laser beam will be described in more detail.

As shown in FIG. 3, the blood sampling unit 13 of this example includes a first part 141 having a laser location space S11 and a second part having a laser guide space S12 for guiding the irradiated laser beam. (142) may be provided.

The first part 141 may have a substantially cylindrical shape.

The first part 141 has a flat lower surface, a cylindrical side surface, and an upper surface, and a space surrounded by the lower surface, side surface, and upper surface is formed inside, and this space is the laser position space S11 ) can be formed.

As described above, the voltage charging unit 131, the laser generating unit 132, and the motor unit 133 may be located in the laser position space S11 of the first part 141, and the power supply unit 11 may additionally be located. can do.

The upper surface of the first portion 141 may include a lens location groove P141 having a circular planar shape in a central portion and an air outlet H141 positioned to face the rotational axis of the motor unit 133 .

As described above, the laser generator 132 may radiate a laser beam toward an upper portion of the blood sampling unit 13 under the control of the operation controller 16 .

The operation control unit 16 transmits a motor driving signal to the motor unit 133 from before a set time before outputting a laser irradiation signal to the laser generator 132 for irradiation of the laser beam and until a set time after the irradiation of the laser beam is completed. can be printed out.

Air rotation of the rotating shaft of the motor unit 133 may occur due to the rotational operation of the motor unit 133, and air pressure of approximately 50 KPa to 70 KPa may be generated.

Air discharged through the air outlet H141 by the air pressure may be discharged into the laser guide space S12 of the second part 142 due to a vortex phenomenon. At this time, the flow of air flows upward along the corresponding surface of the second part 142 in contact with the laser guide space S12.

The second part 142 located above the first part 141 and in contact with the outside has a substantially dome shape, and as described above, may have a laser guide space S12 therein.

A contact portion 1421 having a groove shape where the blood collection site 30 of the body is located may be located in the center of the upper surface of the second portion 142 .

Due to the upper surface of the first part 141 serving as the lower surface of the second part 142, the blood collecting unit 13 is located in the lens location groove P141 and has a lens unit 145 having at least one lens. can be provided. This lens unit 145 may also constitute a part of the blood sampling unit 13 .

As shown in FIG. 3, the laser guide space S12 may have various cone shapes such as a cone or a quadrangular pyramid whose diameter decreases toward the upper side, and has a lens positioning groove P141 and an air outlet ( H141) may be provided. In addition, the upper end of the laser guide space S12 is open to form a laser discharge hole H142.

The laser discharge hole H142 of the laser guide space S12 faces the central portion of the contact portion 1421 and may have a diameter smaller than that of the contact portion 1421 . Accordingly, the entire top of the laser guide space S12 may completely overlap the contact portion 1421 .

At this time, a substantially central portion of the contact portion 1421 facing the laser discharge hole H142 of the laser guide space S12 may also be opened to form a laser irradiation hole H143. Due to this, the laser beam can pass through the open holes H142 and H143 in sequence and be directly irradiated to the corresponding part of the finger 30 located thereon.

Due to the irradiation of the laser beam, the corresponding portion of the finger 30 to which the laser beam is irradiated causes bleeding due to an instantaneous burn due to the high-temperature laser. Accordingly, the person to be measured may apply the blood generated at the corresponding part of the finger 30 (eg, the fingerprint part) to the corresponding part of the blood glucose strip 20 .

In this way, when bleeding occurs in the corresponding body part 30 by the irradiation of the laser beam, soot is generated in the corresponding body part 30 due to the burn, and this soot is disposed on the lower portion of the lens unit 145. may contaminate the lens of

However, in this example, the motor unit 133 operates from before the laser generator 132 operates until after the laser beam is irradiated by the laser generator 132, and the operation of the motor unit 133 This causes a high-pressure air vortex phenomenon.

However, due to the vortex shape of the air, the soot generated during bleeding rises along the flow of air instead of descending toward the lens unit 145 and is located on the finger 30 located at the contact unit 1421 or through the laser irradiation hole ( H143) to fly into the atmosphere.

As a result, since the lens unit 145 is prevented from being contaminated with soot, the characteristics of the laser beam radiated toward the body 30 through the lens unit 145 do not change or greatly decrease even after a period of use.

As described above, since the contact portion 1421 has a recessed groove shape toward the second portion 142, the fingerprint portion of the finger 30, which is a blood sampling site, can be more stably positioned on the contact portion 1421. .

As shown in FIGS. 4A and 4B, the contact portion 1421 is a pain relief ring (R41) positioned on the outside and completely surrounded by the blood collection help ring (R41) located inside the blood collection help ring (R41). R42) may be provided.

At this time, the laser irradiation hole H143 is surrounded by a pain relief ring R42.

The blood collection aid ring R41 may be a single ring that is seamlessly connected and has various planar shapes such as a circular ring, a triangular ring, or a square ring, and as shown in FIG. 4B, has a substantially triangular cross-sectional shape. can Accordingly, the width of the blood collection helper ring R41 may decrease toward the upper side, that is, toward the blood collection body part 30 .

The pain relief ring R42 may be arranged such that a plurality of protrusions 421 are spaced apart in a conical shape, as shown in FIG. 4A. Accordingly, the two adjacent protrusions 421 may be in a disconnected state. Each protrusion 421 has the same shape, and may also have a triangular cross-sectional shape, as shown in FIG. 4B.

However, in an alternative example, each protrusion 421 may have a shape that may cause pain, such as tenderness, to a body part with which it is in contact, such as a cone shape of various shapes such as a triangular pyramid or a quadrangular pyramid instead of a cone.

At this time, the protrusion 421 constituting the pain relief ring R42 has a cross-sectional shape of approximately an isosceles triangle, while the blood collection aid ring R41 has a larger curvature of the inner side than the outer side, so that the length of the inner side is greater than the length of the outer side. can be long

In addition, the height H41 of the blood collection aid ring R41 may be higher than the height H42 of each protrusion 4521 of the pain relief ring R42.

In this example, the blood collection aid ring R41 and the pain relief ring R42 may contain the same material or different materials, for example, an elastic material such as natural rubber or silicon. there is.

At this time, the degree of hardness of the blood collection aid ring R41 and the pain relief ring R42 may be the same as or different from each other. When the hardness of the blood collection aid ring (R41) and the pain relief ring (R42) are different from each other, the hardness of the pain relief ring (R42) is greater than that of the blood collection aid ring (R41) and is harder than the blood collection aid ring (R41). can do.

Therefore, when the finger 30, which is the blood collection site, is located on the contact part 1421, it primarily contacts the blood collection helper ring R41 and the corresponding part of the finger 30, and a downward force is applied from the finger 30. As it is applied, the contact portion of the finger 30 in contact with the blood collection help ring R41 is compressed by the blood collection help ring R41, so that the portion surrounded by the blood collection help ring R41 is pressed downward.

Due to this pressing phenomenon, the skin of the portion surrounded by the blood collection aid ring R41 is stretched, and the skin of the portion surrounded by the blood collection aid ring R41 temporarily becomes thin.

Accordingly, the laser beam can more easily pass through the thinned skin, and the blood collection operation can be performed quickly and easily.

At this time, the blood collection help ring R14 has a horn shape, and the inner surface of the blood collection help ring R14 has a curved shape according to the curved surface of the finger 30, so that the finger pressed by the blood collection help ring R14 ( 30) can be stretched more efficiently.

In this way, when the skin of the corresponding area becomes thin primarily by the blood collection help ring R41 due to the pressure of the finger 30, the corresponding portion of the finger 30 in contact with the pain relief ring R42 secondarily It can be pressed and compressed by the pain relief ring (R42).

At this time, since the pain relief ring R42 is provided with a plurality of conical projections 421 spaced apart from each other, the portion of the finger 30 contacting each projection 421 is the projection 421 in contact with each other. This can cause tenderness, and this tenderness can alleviate pain that occurs when a laser beam is irradiated to a corresponding part of the finger 30 .

Therefore, when blood is collected by the laser beam, the magnitude of pain felt by the subject is greatly reduced compared to when the horn-shaped protrusion 421 does not exist.

Returning to FIG. 1 again, the blood glucose signal measurer 14 may be connected to the operation control unit 16 and may have a strip insertion hole into which the blood glucose strip 20 is inserted.

In this example, the blood glucose measurement switch may change its state when the blood glucose strip 20 is normally inserted into the strip insertion hole and output a signal of the corresponding state to the operation controller 16 . Due to this, the blood glucose measurement switch may function as a blood glucose strip 20 insertion detection unit.

However, in an alternative example, the blood glucose measurement switch may be a separate switch whose operating state changes according to a user's manipulation regardless of whether or not the blood glucose strip 20 is inserted into the strip insertion port.

Accordingly, the subject may radiate laser to a desired body part 30 to cause bleeding, and then apply blood (ie, a specimen) to the corresponding position of the blood glucose strip 20 to prepare for blood glucose measurement.

Then, the test subject may measure blood glucose by inserting the blood glucose strip 20 coated with blood into the strip insertion hole.

In this way, when the blood glucose strip 20 is inserted into the strip insertion port and applied from the blood glucose measurement switch to the operation controller 16 of a signal in a corresponding state, the operation controller 16 applies a voltage to the blood glucose signal measurement unit 14, The blood glucose signal measuring unit 14 may be operated.

Accordingly, the blood sugar strip 20 outputs a current corresponding to the blood sugar level of the applied blood by the voltage applied through the blood sugar signal measuring unit 14 and applies the current to the blood sugar signal measuring unit 14, thereby generating a blood sugar signal. The measurement unit 14 may convert a signal applied from the blood glucose strip 20 into a digital state and apply the converted signal to the operation control unit 16 .

The body temperature measuring unit 15 may include a body temperature measuring device that measures the body temperature of the subject, and may include, for example, an infrared body temperature device using infrared rays.

The operation controller 16 is a control module that controls overall operations of the laser blood collection device 10 and may be a processor.

Therefore, as described above, the operation control unit 16 controls the charging operation for the capacitor of the voltage charging unit 131 according to the operating state of the charging and level switches, and when it is determined that the laser irradiation switch is operated, the motor unit After operating 133, a laser irradiation signal may be applied to the laser generator 133 to control the irradiation operation of the laser.

In addition, when it is determined that the blood glucose measurement switch is operated, the operation control unit 16 operates the blood sugar signal measurement unit 14 to measure the blood glucose strip 20 using the measurement current applied from the blood glucose signal measurement unit 14. The blood sugar level of the applied specimen can be determined.

Also, when the body temperature measurement switch is operated, the operation controller 16 may determine the body temperature of the subject by using the body temperature measurement signal applied from the body temperature measurement unit 15 .

The storage unit 17 is connected to the operation control unit 16 and stores data necessary for the operation of the laser blood sampling device 10 or data generated during operation, and may be a memory.

The output unit 18 is connected to the operation control unit 16 and can visually output information under the control of the operation control unit 16 .

Therefore, the output unit 18 can display an image corresponding to the image data output from the operation controller 16 on the screen, and can be used in a liquid crystal display or an organic light emitting diode display. , at least one of a flexible display and a 3D display.

Next, with reference to FIG. 2 , the operation of the laser blood collection device 10 having this structure will be described.

First, the operation control unit 16 may determine whether the power switch is in an on state by reading a signal applied from the power switch (S11).

When it is determined that the power switch is in an on state, the operation control unit 16 outputs a driving signal to the power supply unit 11 to operate the power supply unit 11 (S12). Accordingly, the power supply unit 11 may generate and output power necessary for the operation of the laser blood sampling device 10 .

Next, the operation control unit 16 may determine whether the charge and level switch is operated by reading the signal applied from the charge and level switch (S13).

Accordingly, when it is determined that the charge and level switch is operated, the operation controller 16 may determine the selected charge level using a signal applied from the charge and level switch (S14).

Next, the operation control unit 16 determines the size of the charging voltage according to the determined charging level using the data stored in the storage unit 17 and applies a charging signal having a corresponding magnitude to the voltage charging unit 131. It can (S15).

Accordingly, the voltage charging unit 131 may perform a charging operation up to a predetermined level of voltage and output a charging voltage feedback signal, which is a signal related to the charging voltage, to the operation control unit 16 .

The operation control unit 16 may read the charging voltage feedback signal applied from the voltage charging unit 131 to determine the charging level of the voltage charging unit 131 (S16, S17), and output a signal according to the charging level to the output unit ( 18) so that the subject can visually check the current charging state for laser irradiation.

Therefore, when it is determined that the charging state of the voltage charging unit 131 is completely charged up to a voltage of a predetermined level by the charging voltage feedback signal (S17), the operation control unit 16 transmits a charging signal applied to the voltage charging unit 131. It can be stopped (S18).

Next, the operation control unit 16 may read a signal applied from the laser irradiation switch to determine whether the laser irradiation switch is in an operated state, that is, an on state (S19).

When it is determined that the laser irradiation switch is turned on (S19), the operation control unit 16 outputs a driving signal to the motor unit 133 to rotate the motor of the motor unit 133, and then to the laser generator 132 to generate a laser beam. An irradiation signal may be output (S110). Then, the operation control unit 16 may stop the rotation of the motor unit 133 by stopping the driving signal applied to the motor unit 133 after a set period of time after outputting the laser irradiation signal.

Therefore, the laser generator 132 may output a laser beam after rotation of the motor unit 133 starts. The intensity of the laser irradiated from the laser generator 132 may be determined according to the magnitude of the charging voltage of the voltage charging unit 131, that is, the magnitude of the selected charging level.

Bleeding occurs in a part of the subject's body located at the contact part 1421 by such laser irradiation, and the subject applies blood as a specimen to the corresponding position of the blood glucose strip 20, and then measures the blood glucose level of the specimen. To do this, the blood glucose strip 20 coated with the sample may be inserted into the strip insertion port of the blood glucose signal measuring unit 14 .

When a signal of the corresponding state is input from the blood glucose measurement switch by the insertion operation of the blood glucose strip 20, the operation controller 16 goes to steps S13 and S111 to turn on the blood glucose measurement switch by using the state of the input signal. state may be determined (S111).

Accordingly, when it is determined that the blood glucose measurement switch is in an on state, the operation control unit 16 applies a voltage of a corresponding magnitude to the blood glucose signal measurement unit 14 to operate the blood glucose signal measurement unit 14 (S112), and then operates the blood glucose signal measurement unit 14. A signal applied from the measuring unit 14 can be read to read the measured current for the specimen (S113).

Next, the operation control unit 16 determines the blood glucose level corresponding to the measured current using the magnitude of the measured current applied and the data stored in the storage unit 17, and outputs the determined blood glucose aberration to the output unit 18. It can be output as (S114, S115).

Therefore, the person to be measured can check the current blood sugar level by checking the blood sugar level output through the output unit 18 .

However, when it is determined that the charging/level switch and the blood glucose measurement switch are not operated, the operation control unit 16 may read a signal applied from the body temperature measurement switch to determine whether the body temperature measurement switch is operated ( S116).

Accordingly, when it is determined that the body temperature measurement switch is in an on state, the operation controller 16 may apply a driving voltage to the body temperature measurement unit 15 to operate the body temperature measurement unit 15 (S117).

Accordingly, after the body temperature measurement unit 15 detects the temperature of the corresponding body part of the subject, a body temperature measurement signal corresponding to the sensed temperature may be output to the operation controller 16 .

The operation control unit 16 may determine the body temperature of the subject by reading the body temperature measurement signal applied from the body temperature measurement unit 15, and then output the determined body temperature to the output unit 18 (S118-S120). At this time, the operation control unit 16 may determine the body temperature of the subject by determining a temperature corresponding to the magnitude of the body temperature measurement signal using the data stored in the storage unit 17 .

In this way, the laser blood sampling device 10 of the present example can realize not only the blood sampling operation but also the operation of determining the blood glucose level at the same time, so there is no need to separately purchase a blood glucose meter.

In addition, since the laser blood collection device 10 of the present example can measure body temperature as well as blood sugar measurement, there is no need to provide a separate body temperature device. However, in an alternative example, at least one of the blood glucose measurement function and the body temperature measurement function may be omitted, and in this case, a structure related to the omitted function may also be omitted.

In this way, since blood collection, blood glucose level determination, and body temperature measurement can all be performed only with the laser blood collection device 10 of the present example, the economic burden and inconvenience of purchasing and storing multiple medical devices with different functions are greatly reduced. can
