[0035] In this specification, some of the actions or functions described as being performed by a terminal or device may also be performed by a server connected to the terminal or device. Similarly, some of the actions or functions described as being performed by a server may also be performed by a terminal or device connected to the server.

[0036] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0037] Figure 1a A perspective view of a blood sampling and blood sugar measuring device 10 is shown. Figure 1b A front view of the blood sampling and blood sugar measuring device 10 is shown. Figure 1c A side view of the blood sampling and blood sugar measuring device 10 is shown.

[0038] refer to Figure 1a to Figure 1c The blood sampling and blood glucose measuring device 10 may include a housing 100 , a plurality of buttons 101 , a display portion 102 , a test strip ejection button 103 , a blood glucose test strip connector 115 and a contact unit 400 .

[0039] The housing 100 forms the appearance of the blood sampling and blood sugar measuring device 10, and a structure for irradiating the irradiated portion with laser light may be located inside the housing 100. The housing 100 may be formed into a shape that is easy for the user to hold directly.

[0040] The plurality of buttons 101 may include buttons related to a power switch and an intensity adjustment unit. The power switch can turn on and off a power source as an energy source of the laser. The intensity adjustment unit can adjust the intensity of the laser oscillated from the laser oscillation unit 200.

[0041] The display unit 102 can display the blood sugar level measured from the collected blood. In addition, the display unit 102 can display the intensity adjusted by the intensity adjustment unit.

[0042] The plurality of buttons 101 may be physical buttons or touch panels related to the power switch and the intensity adjustment unit, and the display unit 102 may be a liquid crystal display. However, the present invention is not limited thereto, and the power switch, the intensity adjustment unit, and the display unit may be displayed on a touch display, and the power or the intensity of the laser may be adjusted as the user touches the touch display.

[0043] When the blood glucose test strip 110 is inserted into the blood glucose test strip connector 115, the test strip ejection button 103 can cause the blood glucose test strip 110 to be ejected from the blood glucose test strip connector 115. Such a test strip ejection button 103 can be configured as a physical button or a touch panel. For example, when a user applies a prescribed pressure to the test strip ejection button 103, the blood glucose test strip 110 inserted into the blood glucose test strip connector 115 can be automatically ejected by the test strip ejection button 103. That is, the blood glucose test strip 110 is ejected from the blood glucose test strip connector 115 by the test strip ejection button 103, so that the user does not need to directly remove the blood glucose test strip 110 stained with blood by hand, thereby preventing infection caused by the blood glucose test strip 110.

[0044] The blood glucose test strip 110 formed with a blood glucose measurement sensor may be inserted into the blood glucose test strip connector 115. After the blood glucose measurement is completed, the blood glucose test strip 110 may be ejected from the blood sampling and blood glucose measurement device 10 by the user.

[0045] A blood sugar measuring sensor may be formed inside the blood sugar test strip 110. As a unit for analyzing blood sugar in blood, the blood sugar test strip 110 may output a current corresponding to the amount of blood sugar in the supplied blood. The blood sugar test strip 110 may be a consumable that is replaced each time blood sugar is measured. The blood sugar test strip 110 includes an electrode portion for measuring blood sugar, and a reagent may be coated on the electrode portion. The electrode portion may include a working electrode and a reference electrode.

[0046] The contact unit 400 may be formed at a portion of one side of the housing 100. For example, the contact unit 400 may include a disposable cap 120 for contacting the irradiated portion and a disposable cap connector 130 formed to combine the disposable cap 120 and the housing 100.

[0047] For blood collection, the disposable cap 120 can be combined with a disposable cap connector 130 formed on the body of the housing 100. For example, the disposable cap 120 can be connected to a disposable cap connector 130 located on a beam barrel 410 (see FIG. Figure 2 ) is combined with the disposable cap connector 130 in front of the disposable cap 120. This is to facilitate the combination or separation between the disposable cap 120 and the disposable cap connector 130 in order to replace the disposable cap 120, thereby, after the existing disposable cap is separated from the disposable cap connector 130, a new disposable cap is combined with the disposable cap connector 130, thereby preventing infection between patients caused by blood sampling. The disposable cap 120 is in contact with the skin and can minimize the odor, smoke and noise generated during the puncture of the skin. In particular, the shaft cylinder 410 can be cut off from direct contact with the skin, thereby preventing the shaft cylinder from being contaminated. In addition, each user replaces and uses the disposable cap 120, thereby preventing infection between patients who use the blood sampling and blood sugar measuring device 10 together.

[0048] The disposable cap 120 may include a cap body 121, an opening 122, and a support surface 123 supported at a contact point along the periphery of the opening 122. For example, the cap body 121 may be formed in a circular plate shape, and the opening 122 may be formed in the central portion thereof along the axial direction. In addition, the cap body 121 may include at least one handle portion 124 formed to extend from the support surface 123.

[0049] The user can easily attach and detach the disposable cap 120 to the blood sampling and blood sugar measuring device 10 through the handle 124. The opening 122 may have an area sufficient to ensure the path of the laser so that the laser output from the blood sampling and blood sugar measuring device 10 is not interfered by the through hole 125 of the disposable cap 120.

[0050] In addition, the disposable cap 120 is designed to be smaller than the average area of ​​the fingertips that mainly contact the disposable cap 120, so that appropriate pressure can be provided to the irradiated part. Similarly, the support surface 123 can ensure an appropriate area so that the disposable cap 120 can be closely attached to the contact point with the disposable cap 120.

[0051] In addition, the disposable cap 120 may include a fastening portion 126 coupled to the cap body 121. The fastening portion 126 may couple the cap body 121 to the shaft cylinder 410 via the disposable cap connector 130. For example, the fastening portion 126 is located at the peripheral portion of the back side of the disposable cap 120, and is formed to protrude rearward, and includes a protrusion formed on the inner surface. In addition, the protrusion is engaged with the fastening groove 131 formed in the disposable cap connector 130, thereby preventing the disposable cap 120 from being accidentally separated.

[0052] In order to perform blood sampling, the disposable cap connector 130 can be combined with the disposable cap 120. For example, when the disposable cap connector 130 is combined with the disposable cap 120, the disposable cap connector 130 can allow the laser generated by the laser oscillation unit 200 to pass through the shaft cylinder 410, and the laser passing through the shaft cylinder 410 is irradiated to the irradiated part through the disposable cap 120 combined with the disposable cap connector 130.

[0053] Such a disposable cap connector 130 may include a fastening groove 131 and a laser irradiation portion 132. For example, the disposable cap connector 130 may be combined with the disposable cap 120 through the fastening groove 131. Wherein, when the disposable cap 120 is combined with the disposable cap connector 131 through the fastening groove 131, the disposable cap connector 130 may allow the laser generated by the laser oscillation unit 200 to be irradiated through the laser irradiation portion 132.

[0054] The contact unit 400 can irradiate the laser to the irradiated part. For example, the contact unit 400 includes an internal structure located inside the housing 100, such as at least one measuring sensor for detecting contact of the irradiated part, a contact detection circuit connected to the measuring sensor, a barrel 410 for passing the laser, etc., and through the internal structure included in the contact unit 400, the laser generated by the laser oscillation unit 200 can be irradiated to the irradiated part. Figure 2 To be described later.

[0055] Figure 2 1 is a schematic diagram showing the internal structure of a blood sampling and blood sugar measuring device according to an embodiment of the present invention. Figure 2 The blood sampling and blood glucose measuring device 10 may include a housing 100 , a laser oscillation unit 200 , a blood glucose measuring unit 300 , a contact unit 400 , a blood glucose test strip insertion unit 500 , a controller 600 and a communication module 650 .

[0056] The laser oscillation unit 200 is housed inside the housing 100 and can generate laser light for blood collection. For example, the laser oscillation unit 200 can generate light energy such as a laser selected from one of a gas laser, a liquid laser, a solid laser, and a semiconductor laser by receiving electrical energy and amplifying light, and emit it to the outside front.

[0057] The blood sugar measuring unit 300 is accommodated inside the housing 100 and can measure blood sugar.

[0058] For example, the blood glucose measurement unit 300 may include a circuit module that detects an electrical signal through the blood glucose test strip 110 and converts the value of the detected electrical signal into a blood glucose value.

[0059] The blood sugar measuring unit 300 can measure the concentration of blood sugar using amperometry technology.Among them, amperometry refers to a method of performing oxidation-reduction of a substance through an electrode and converting it into an electric current. The electrode active substances of enzymes such as those participating in oxygen reaction or microbial reaction can react with a power source and output as a current value. By measuring the current, the substrate concentration of glucose, ascorbic acid, etc. can be measured, so that amperometry is mainly used for various biosensors. The measurement method using amperometry can include a balance method (normal method) for measuring a normal current proportional to the concentration and a rate method using the relationship between the rate change of the current and the concentration. For example, the blood sugar measuring unit 300 can measure the blood sugar concentration using the current generated when a specified voltage is applied to the blood sugar test strip 110 within a specified time. When a specified voltage is applied to the blood sugar test strip 110 within a specified time, a current proportional to the blood sugar concentration is generated, and the blood sugar concentration can be measured by applying the current value to the relationship between the blood sugar concentration and the current.

[0060] For another example, the blood sugar measuring unit 300 further includes an optical measuring sensor, and may further include a circuit module that detects an optical signal through the optical measuring sensor and converts the detected optical signal into an electrical signal.

[0061] The blood sugar measurement unit 300 can use an optical measurement sensor to measure blood sugar in a non-invasive manner or by blood sampling. For example, the optical measurement sensor outputs light with a wavelength between 300nm and 3000nm, and after the absorbed light or reflected light is converted into a current value by a photodiode (PD), the measured value can be expressed as a blood sugar value. For example, the blood sugar measurement unit 300 uses an optical measurement sensor to generate light and irradiates the light to the blood. For the reflected light, the light reflection measurement method is used to analyze the change in the intensity of the reflected light over time, so that the blood sugar level can be measured based on the analysis result.

[0062] For another example, the blood sugar measurement unit 300 uses an optical measurement sensor to irradiate light of at least one wavelength to the blood, calculates the absorbance (the absorbance of light according to a specific line segment) from the reflected light or the transmitted light, and can measure the components of the blood based on the absorption spectrum.

[0063] The contact unit 400 includes a disposable cap 120 and a disposable cap connector 130 formed on the outside of the housing 100, and may include at least one measuring sensor formed on the inside of the housing 100 for detecting contact of the irradiated portion and a contact detection circuit connected to the at least one measuring sensor. Figure 1a to Figure 1c Description has been made, so detailed description will be omitted.

[0064] The contact unit 400 may include a barrel 410 for irradiating laser light accommodated inside the housing 100 .

[0065] The shaft cylinder 410 is housed inside the housing 100 and provides a path for the laser irradiated by the laser oscillation unit 200 to pass through and irradiate the skin. To this end, the blood sampling and blood sugar measuring device 10 may also include a forward and backward moving unit (not shown), which is used to move the shaft cylinder 410 in the forward and backward direction. In other words, the forward and backward moving unit moves the shaft cylinder 410 forward and backward to adjust the distance between the user's skin and the focusing lens, so that the size of the laser spot irradiated to the irradiated part of the user can be adjusted. For example, when the user adjusts the size of the laser spot through multiple buttons 101, the position of the shaft cylinder 410 can be adjusted by driving the motor, but it is not limited to this, and the position of the shaft cylinder 410 can also be moved in the forward and backward direction manually.

[0066] The contact unit 400 may include a pressure sensor for detecting the pressure generated when the irradiated portion contacts the disposable cap 120. When the pressure value detected by the pressure sensor is greater than a preset value, the controller 600 may operate the laser oscillation unit 200.

[0067] The contact unit 400 may come into contact with at least one measuring sensor disposed inside the housing 100 .

[0068] Among them, in order to detect whether the blood sampling and blood glucose measuring device 10 is working safely, at least one measuring sensor may include, for example, a disposable cap 120 detection sensor, a blood glucose test strip 110 detection sensor, a contact sensor for detecting contact with the irradiated part, a pressure sensor for measuring the pressure applied to the irradiated part, etc.

[0069] For example, the blood sampling and blood sugar measuring device 10 can simultaneously perform contact sensing and pressure sensing of the blood sampling and blood sugar measuring device 10 through the micro array lens (MLA) and pogo pin (Pogo Pin) of the contact unit 400 or a conductor capable of detecting current.

[0070] For example, contact sensors on both sides of the aperture of the blood sampling and blood sugar measuring device 10 and a pressure sensor for measuring a specific pressure (for example, sensing when the voltage or current is above 0.1v or above 0.1uAh) can be used to simultaneously perform contact detection and pressure detection measurements.

[0071] For example, when a prescribed pressure is applied, the spring pins of the blood sampling and blood sugar measuring device 10 can detect the pressure and connect the contact detection circuit by means of the applied pressure through the spring pins.

[0072] The disposable cap 120 detection sensor can detect whether the disposable cap 120 is reused or replaced. Among them, the disposable cap 120 detection sensor can be a light sensor.

[0073] For example, when the disposable cap 120 is reused, the surface through which the laser passes becomes opaque, so that blood sampling cannot be performed when it is reused. To prevent this, when the surface reflectivity of the transparent window through which the laser passes is lower than a specific value, the disposable cap 120 detection sensor can detect whether it is reused or not. That is, when the disposable cap 120 detection sensor determines that the surface reflectivity of the transparent window is lower than a specific value, an alarm about the reuse of the disposable cap 120 can be output through the display unit 102 or sound.

[0074] Alternatively, the disposable cap 120 detection sensor can use a pressure or push-pull switch to detect whether the disposable cap 120 is a new cap or has been replaced. For example, a pressure switch is present at the cap insertion portion at the front end of the aperture, and when the disposable cap 120 is first inserted into the blood sampling and blood glucose measuring device 10, the pressure switch is pressurized, so that the disposable cap 120 detection sensor identifies a new disposable cap, and when the disposable cap 120 is removed after laser oscillation, if the pressure switch is released for more than a few micro-time periods, it can be detected that the disposable cap has been replaced with a new one. When such a signal does not exist, the blood sampling and blood glucose measuring device 10 can output an alarm to allow the user to replace the disposable cap 120.

[0075] For the blood glucose test strip, there are multiple circuit lines inside the test paper, so the blood glucose test strip 110 detection sensor can measure the resistance value of a specified circuit line. For example, after the blood glucose test strip 110 is inserted into the blood glucose test strip connector 115 for inserting the blood glucose test strip, if the blood glucose test strip 110 detection sensor detects the resistance value of a specific circuit pattern, the insertion of the blood glucose test strip 110 can be detected.

[0076] The blood sugar test strip insertion unit 500 is formed at another portion of one side of the housing 100 and enables the blood sugar test strip 110 to be inserted, wherein the blood sugar test strip 110 is formed with a blood sugar measuring sensor 510 (refer to Figure 3 ), the blood glucose measurement sensor 510 sends and receives signals with the blood glucose measurement unit 200 to achieve blood glucose measurement. For example, the blood glucose test strip 110 can be inserted into the blood glucose test strip connector 115 of the blood glucose test strip insertion unit 500, and the blood glucose test strip 110 pops out after completing the blood glucose measurement.

[0077] The blood glucose test strip insertion unit 500 can function as an interface between the blood glucose test strip 110 and the blood sampling and blood glucose measuring device 10 while performing the functions of inserting and ejecting the blood glucose test strip 110. In order to function as an interface, the blood glucose test strip insertion unit 500 may include a terminal for applying a voltage to the electrode portion of the blood glucose test strip 110 and a terminal for detecting a current received from the electrode portion. Such a terminal can not only function as an interface, but also function as a unit providing an elastic force for ejecting the blood glucose test strip 110.

[0078] For example, the blood glucose test strip insertion unit 500 can confirm whether the blood glucose test strip 110 is inserted into the blood glucose test strip connector 115. When the blood glucose test strip 110 is inserted into the blood glucose test strip connector 115, a predetermined current flows between the blood sampling and blood glucose measuring device 10 and the blood glucose test strip 110, thereby the controller 600 can detect whether the blood glucose test strip 110 is inserted.

[0079] The controller 600 can control the laser oscillation unit 200. For example, when the user applies a signal, the pressure generated when the irradiated part contacts the disposable cap is detected by the pressure sensor included in the contact unit 400, and the pressure value of the pressure sensor is greater than a preset value, the controller 600 can make the laser oscillation unit 200 work.

[0080] The controller 600 can adjust the power supply or the intensity of the laser based on the signals input from the plurality of buttons 101. For example, when a control signal of turning on / off is input from the power switch, the controller 600 can turn on / off the power supply as the energy source of the laser. For another example, when a control signal related to the adjustment of the laser intensity is input from the button of the intensity adjustment section, the controller 600 can adjust the forward and backward movement of the barrel 410 based on the adjusted intensity of the laser.

[0081] When the contact unit 400 coupled to the disposable cap 120 contacts at least one measuring sensor, the controller 600 can derive a change value of the current amount of the irradiated portion through the at least one measuring sensor in contact with the contact unit 400 coupled to the disposable cap 120, and can control the operation of the laser oscillation unit 200 based on the derived change value of the current amount. Part of the blood glucose test strip or the disposable cap 120 and the contact unit 400 are formed of metal and contact the sensor of the blood sampling and blood glucose measuring device 10, so that the time point of laser oscillation is confirmed according to the change of the current amount generated by contact with the skin.

[0082] For example, when skin contact is detected within a prescribed time by the skin contact sensor in contact with the contact unit 400, the controller 600 may control the operation of the laser oscillation unit 200 to implement laser oscillation.

[0083] The communication module 650 is formed in the housing 100, and can transmit the blood glucose value data measured by the blood glucose measuring unit 300 to the user terminal connected to the blood sampling and blood glucose measuring device 10. Among them, the blood glucose value data can be displayed through a blood glucose information application installed in the user terminal, and various information according to the user's blood glucose level can also be recommended through the blood glucose information application.

[0084] Figure 3 Schematic diagram for describing the process of blood sampling and blood sugar measurement using a blood sampling and blood sugar measurement device according to an embodiment of the present invention. Figure 3 After the blood sampling and blood sugar measuring device 10 irradiates the user's skin with laser to collect blood, the blood sugar value of the blood collected from the user can be measured through the blood sugar test strip 110.

[0085] For example, when the disposable cap 120 combined with the contact unit 400 contacts the user's skin 800, the laser oscillation unit 200 can generate laser light for blood collection. The contact unit 400 can irradiate the laser light generated by the laser oscillation unit 200 to the user's skin 800 through the shaft cylinder 410. Through this process, blood can be exposed while forming a perforation on a partial area 810 of the user's skin 800.

[0086] Afterwards, when collecting blood from the user's skin 800, the user can move his or her finger toward the blood glucose test strip 110, so that the user's blood 820 exposed by the blood collection can come into contact with the blood glucose test strip 110 including the blood glucose measurement sensor 510 coupled to the blood glucose test strip insertion unit 500. The user's blood glucose can be measured by the blood glucose measurement unit 300.

[0087] According to an embodiment of the present invention, in the blood sampling and blood sugar measuring device 10 , the contact unit 400 and the blood sugar test strip insertion unit 500 may be formed on the same connection structure 700 .

[0088] Therefore, after collecting blood, the user can smoothly move the irradiated portion with blood to the blood glucose test strip 110, thereby providing an advantage of being able to easily measure the blood glucose level of the blood.

[0089] Figure 4a Is used to describe Figure 3 Schematic diagram of a blood glucose test strip. Figure 4b This is a diagram showing the performance of a blood absorbent member made of a superabsorbent resin.

[0090] refer to Figure 4aThe blood glucose test strip 110 may include a blood absorbing component 520, which is made of a super absorbent polymer and is used to absorb residual blood exposed to the peripheral portion of the blood glucose measurement sensor 510. The super absorbent polymer may be configured to be separated from the blood glucose measurement sensor 510 by a predetermined spacing distance (e.g., 0.5 mm or more).

[0091] Conventionally, when a blood glucose test strip is used in a blood measuring device to measure blood glucose, the blood test strip stained with blood is removed after the blood glucose is measured, but in this case, residual blood may splash, thereby contaminating the blood measuring device.

[0092] However, in the present invention, in the peripheral portion of the blood sugar measuring sensor 510 of the blood sugar test strip 110, the superabsorbent resin is configured to be separated from the blood sugar measuring sensor 510 by a prescribed spacing distance, thereby providing the advantage of preventing external contamination by absorbing residual blood 521 on the surface of the blood sugar measuring sensor 510 after blood sugar measurement.

[0093] Figure 4b This is a diagram showing the performance of a blood absorbent member made of a superabsorbent resin.

[0094] Normally, blood 521 is composed of blood cells (about 45%) and plasma (about 55%), and about 91% of the plasma is composed of water.

[0095] When the blood 521 is absorbed by the super absorbent resin material, the super absorbent resin material exhibits a high absorption capacity, such as absorbing the blood 521 and generating a gel form 522 .

[0096] Therefore, when the blood absorption component 520 made of a highly absorbent resin material is arranged at the peripheral part of the blood glucose measurement sensor 510, it can fully absorb the residual blood 521 after the blood glucose measurement is completed, thereby providing the advantage of preventing the blood 521 from contaminating the blood collection and blood glucose measurement device 10 during the process of replacing the blood glucose test strip 110.

[0097] Figure 5 Schematic diagram for describing a heating component of a blood sampling and blood sugar measuring device according to an embodiment of the present invention.

[0098] refer to Figure 5 The blood sampling and blood sugar measuring device 10 may further include a heating component 900, which is formed at another part of one side of the housing 100 and applies heat to the surrounding of the irradiated portion.

[0099] For example, when the user brings the skin 800 of the finger into contact with the disposable cap 120, heat can be applied to the periphery of the irradiated portion by the heating component 900, thereby increasing the blood flow of the blood in the user's skin. Through this process, heat is applied to the user's skin, thereby increasing the blood flow of the blood in the user's skin, and the blood collection effect can be improved.

[0100] This heating component 900 can be formed to be located at the lower end of the blood glucose test strip 110. When the user puts his hand or skin in contact with the disposable cap 120 for blood collection, it can be heated to a temperature that does not cause discomfort due to the heat, thereby increasing the blood flow in the user's skin.

[0101] In the past, when measuring blood sugar in blood collected from a user, negative pressure was used to increase blood flow. However, when using negative pressure, there is a problem that a negative pressure pump is required to move blood to a blood sampling sensor provided in a blood sugar measuring device, or the blood sugar measuring device needs to be processed in a complicated manner.

[0102] However, the present invention can provide an advantage of being able to easily measure blood sugar without using negative pressure.

[0103] Figure 6 1 is a schematic diagram for describing a blood sugar measuring unit including an optical measurement sensor of a blood sampling and blood sugar measuring device according to an embodiment of the present invention.

[0104] refer to Figure 6 The blood glucose measuring unit 300 may further include an optical measuring sensor 1000, which is used to measure at least one of blood glucose level, blood pressure, and oxygen saturation. The optical measuring sensor 1000 may be formed on another part of one side of the housing 100 of the blood sampling and blood glucose measuring device 10.

[0105] For example, when the user brings the skin 800 of the finger into contact with the disposable cap 120, the optical measurement sensor 1000 can use optical measurement and non-invasively or blood sampling to measure the blood sugar level, blood pressure, oxygen saturation, etc. in the skin 800 tissue or in the collected blood. Among them, by comparing the blood sugar level measured by the optical measurement sensor 1000 with the blood sugar level measured by actual blood sampling, the accuracy of blood sugar measurement of the blood sampling and blood sugar measuring device 10 can be improved.

[0106] The above description of the present invention is exemplary, and those skilled in the art to which the present invention belongs can understand that it can be easily transformed into other specific forms without changing the technical ideas or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all aspects and not restrictive. For example, each constituent element described as a single type can also be implemented in a decentralized manner. Similarly, constituent elements described as decentralized forms can be implemented in a combined form.

[0107] The claims described in the text are more able to reflect the scope of the present invention than the above detailed description, and all changes or modifications derived from the meaning, scope and equivalent concepts of the claims should be included in the scope of the present invention.
