Abstract
Description
Laser blood collection device
[0001] The present invention relates to a laser blood collection device, and more particularly, to a laser blood collection device for reducing pain during blood collection.
[0002] Due to changing eating habits, adult diseases such as diabetes are on the rise, and with the advancement of medical technology, many diseases can be predicted and prevented through blood tests alone.
[0003] When collecting blood for a blood test, a lancet or laser is used, and the pain that occurs during the blood collection process causes a lot of physical and mental pain and anxiety to the patient or subject.
[0004] In particular, users who must manage their blood sugar levels through periodic self-blood sugar measurements suffer greatly from the pain and discomfort caused by repeated blood collection movements.
[0005] The problem that the present invention seeks to solve is to reduce the pain of a person receiving blood when collecting blood.
[0006] A laser blood collection device according to one feature of the present invention includes a laser medium unit that outputs a laser beam whose beam diameter changes depending on the intensity of input light, a lamp unit that is spaced apart from the laser medium unit and outputs light to the laser medium unit, and a lens unit that is positioned in front of the laser medium unit and inputs and outputs light applied from the laser medium unit, wherein the beam diameter size is 80% to 95% of the diameter of the laser medium unit.
[0007] The diameter of the laser medium portion may be 3 mm, and the beam diameter may be 2.5 mm to 2.8 mm.
[0008] One end of the laser medium portion adjacent to the lens portion and the other end of the laser medium portion located opposite the one end may have different radii of curvature.
[0009] The radius of curvature of one end of the laser medium portion may be greater than the radius of curvature of the other end of the laser medium portion.
[0010] The radius of curvature of one end of the laser medium portion may be infinite, and the radius of curvature of the other end of the laser medium portion may be 500 mm to 1500 mm.
[0011] The laser blood collection device according to the above characteristics may further include a first laser mirror unit and a second laser mirror unit respectively positioned at both ends of the laser medium unit.
[0012] The laser blood collection device according to the above characteristics may further include a tube having the laser medium unit and the lamp unit built therein.
[0013] The surface roughness of the inner surface of the above-mentioned tube may be smaller than the surface roughness of the outer surface of the above-mentioned tube.
[0014] The laser blood collection device according to the above characteristics may further include a first reflector and a second reflector located at each end of the tube and blocking each end.
[0015] Each of the first and second reflectors in contact with the inner side of the above-mentioned tube may have a polished surface, and each of the other surfaces positioned opposite the one surface may be a non-polished surface, and the surface roughness of the polished surfaces of the first and second reflectors may be smaller than the surface roughness of the non-polished surfaces of the first and second reflectors.
[0016] The first reflector and the second reflector may each include a through hole for emitting heat.
[0017] The laser blood collection device according to the above characteristics may further include a capacitor unit located next to the lamp unit and an operation control unit connected to the capacitor unit, which controls a charging operation for charging a voltage of a corresponding size according to the control signal by applying a control signal to the capacitor unit and a discharging operation for applying the charged voltage to the lamp unit, thereby controlling a light-emitting operation of the lamp unit.
[0018] According to these features, laser blood collection can be performed by reducing the laser's output energy and irradiating it onto the subject's skin. Therefore, due to the reduced laser output energy, the patient's pain during the laser irradiation is significantly reduced, significantly improving user convenience.
[0019] This can significantly reduce the pain and anxiety associated with blood draws for users who need to draw blood frequently, such as severe diabetics who need to measure their blood sugar levels daily.
[0020] Additionally, instead of using reflective materials, the reflectivity of the inside of the tube is improved by abrading the inside of the tube, and reflectors are used at both ends of the open tube to supplement the amount of light supplied to the lamp. This can reduce the manufacturing cost and manufacturing time of the laser lancing device compared to increasing the reflectivity of the tube using reflective materials.

[0043] In this application, each step described may be performed regardless of the listed order, except in cases where a special causal relationship requires that the steps be performed in the listed order.
[0044] In this application, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.
[0045] Hereinafter, a laser blood collection and blood sugar measurement device (1) according to one embodiment of the present invention will be described with reference to the attached drawings.
[0046] As illustrated in FIGS. 1 to 6 and 21, the laser blood collection and blood glucose measurement device (1) of the present example may include a case portion (10) having a front case (e.g., a first case) (101), a rear case (e.g., a second case) (102) and a laser protection case (103), a battery module (30) located in the case portion (10) and having a switch group (20), a battery (31) and a battery charging portion (32), a laser blood collection module (40), a blood glucose measurement module (50), and an information output portion (60).
[0047] At least some of these components may also constitute a laser lancing device.
[0048] The front case (101) may be positioned at the front, for example, in FIGS. 1 to 6, and the rear case (102) may be positioned at the rear, for example, in FIGS. 1 to 6.
[0049] The front case (101) and the rear case (102) can be coupled to each other as shown in Fig. 2. At this time, the coupling state of the front case (101) and the rear case (102) can be safely maintained by coupling by a coupling member such as a screw (200).
[0050] Accordingly, the laser blood collection and blood sugar measurement device (1) of the present example may have an internal space surrounded by a front case (101) and a rear case (102), and components of the laser blood collection and blood sugar measurement device (1) may be positioned within this space.
[0051] The front case (101), with reference to FIGS. 4 to 6, has a front and side closed and a rear part that can be opened.
[0052] The front case (101) may be provided with a front case body (11) and a protective cover (12) located on the upper portion of the front case body (11).
[0053] The front case body (11) may have a roughly oval-shaped plane shape, the rear part may be open, and may have a front side (FS11) and a side side (SS11) connected to the front side (FS11).
[0054] At this time, a plurality of mounting portions (H111-H116) may be present on the front surface (FS11) of the front case body (11) on which at least a portion of the switch group (20) and components constituting the laser blood collection module (40) may be positioned. These mounting portions (H111-H116) may have a groove shape that is recessed in the corresponding portion of the front case body (11), a hole shape formed by penetrating the corresponding portion of the front case body (11), or a groove shape that has a hole inside the groove.
[0055] The protective cover (12) is connected to the upper part of the front case body (11) and can protect the connected part from foreign substances, etc.
[0056] At this time, the connection between the protective cover part (12) and the corresponding part of the front case body (11) can be performed using a groove and a protrusion, but is not limited thereto.
[0057] The protective cover (12) may have a roughly semi-elliptical flat shape, and may have a convex shape with a portion protruding toward the front.
[0058] A mounting portion where components of the switch group (20) can be positioned can also be positioned on the protective cover portion (12).
[0059] The rear case (102) combined with the front case (101) has the side (SS12) and the rear (BS12) closed and the front can be opened.
[0060] Therefore, by combining with the front case (101), the rear part of the open front case (101) and the front part of the open rear case (102) can communicate with each other, and thus, an empty space surrounded by the front case (101) and the rear case (102) can be located inside the case part (10).
[0061] The rear case (102) of this example may be provided with a mounting hole (H121, H122) where a switch group (20) and an information output unit (60) are located, a test strip insertion hole (H123) into which a blood sugar strip is inserted, and a terminal insertion hole (H124) for supplying external power.
[0062] An electrode pattern (e.g., a reference electrode pattern and a working electrode pattern) may be positioned within the test strip insertion port (H123) to detect whether a blood glucose test strip has been inserted and used. These electrode patterns positioned within the test strip insertion port (H123) may be positioned to correspond to the electrodes (e.g., a reference electrode and a working electrode) positioned on the blood glucose test strip.
[0063] Accordingly, when a blood sugar test strip is normally inserted into the test strip insertion port (H123), the electrode patterns of the test strip insertion port (H123) and the electrodes of the inserted blood sugar test strip, which are positioned correspondingly to each other, can be physically connected by contacting each other. Accordingly, an input / output operation of an electric signal can be performed by the physical connection between the corresponding electrode patterns and electrodes. Accordingly, the laser blood collection and blood sugar measurement device (1) can use these electric signals to determine whether a blood sugar test strip has been inserted into the test strip insertion port (H123) and to calculate a blood sugar index using the electric signal generated after blood administration (hereinafter, this electric signal is referred to as a 'blood sugar signal').
[0064] Since the structure of this blood sugar test strip and the blood sugar measurement operation using this blood sugar test strip are already known, a detailed description thereof will be omitted.
[0065] The switch group (20) generates a signal to control the operation of the laser blood collection and blood sugar measurement device (1) of this example, so that the operation of the laser blood collection module (40) and the blood sugar measurement module (50) can be controlled.
[0066] This switch group (20) may, as an example, include a power switch section (201), a contact detection switch section (202), a safety switch section (203), a menu selection switch section (204), a first movement switch section (205), a second movement switch section (206), and a reset switch (207), as shown in FIG. 21.
[0067] The power switch unit (201) is used to start a blood collection operation or blood sugar measurement operation using a laser blood collection and blood sugar measurement device (1), and can generate an operation start signal.
[0068] This power switch unit (201) may be equipped with a power switch button (211) whose state changes according to the user's action and a power switch (212) whose state changes according to the state of the power switch button (211). In this example, the user may be a subject or a person drawing blood.
[0069] The power switch button (211) can be mounted in the mounting hole (H121) of the rear case (102) and can be controlled by the user to change the state of the power switch (2102) to an operating state (e.g., on state) or an inoperable state (e.g., off state).
[0070] Therefore, when a user operates the power switch (212) using the power switch button (201), the power switch (212) can output an operation start signal in an operating state to the laser blood collection module (40).
[0071] In the laser blood collection and blood sugar measurement device (1) of this example, when power for operation is supplied by the operation of the power switch unit (201), the power switch (212) is operated by the power switch button (211) for a set time (e.g., 2 seconds) or no operation is performed for a set time (e.g., 2 minutes), the power supply is cut off so that the operation of the laser blood collection and blood sugar measurement device (1) is terminated.
[0072] The contact detection switch unit (202) can be located on the front case (101), and its state can change depending on whether it is in contact with the skin of the subject of blood collection, thereby detecting whether the corresponding part of the laser blood collection and blood glucose measurement device (1) is in contact with the corresponding part of the skin of the subject of blood collection for blood collection.
[0073] This contact detection switch unit (202) may change its state by contacting the skin of the subject of blood collection and pressing the skin, thereby changing the distance from the laser output module unit (403).
[0074] For example, the contact detection switch unit (202) may be provided with a push button (221) whose distance from the laser output module unit (403) changes by an externally applied physical force, a laser irradiation button (222) whose state (e.g., position) changes depending on the state of the push button (221), for example, depending on the change in the distance from the laser output module unit (403), and a laser irradiation switch (223) whose state, for example, whether it is operated, is determined depending on the change in the state of the laser irradiation button (222).
[0075] In this example, the push button (221) may be a laser button for generating a laser and irradiating it toward the skin of the subject of the blood collection.
[0076] The position of this push button (221) may change due to the force applied by the pressing action of the skin when it comes into contact with the skin of the corresponding part of the subject of the blood collection, and thus the distance from the laser output module (403) may change.
[0077] These push buttons (221) can be inserted and positioned in the push button mounting hole (H12) formed in the protective cover part (12), as shown in FIG. 2.
[0078] At this time, an elastic member (not shown) such as a spring having elasticity may be mounted within the push button mounting hole (H12).
[0079] Due to this, when a physical force is applied from the outside by the user, the push button (221) can move backward from the initial position, and when the applied force is released, the push button (221) can move forward and return to the initial position.
[0080] For example, when a user applies force after bringing the push button (221) mounted on the protective cover (12) into contact with the corresponding location on the skin where blood is to be collected, the push button (221) can move backward due to the compression action of the elastic member.
[0081] Also, conversely, when the force applied toward the skin is removed, for example, when the contact between the push button (221) and the skin is released, the push button (221) can move to the initial position by the restoring force of the elastic member, and thus, the push button (221) can move forward and be positioned at the initial position.
[0082] In this way, the push button (221) of the present example can move in a direction (e.g., forward and backward direction) (X) determined by a force applied from the outside. At this time, laser irradiation can be performed along the direction (X). In the present example, the direction (X) may be the optical axis direction.
[0083] This push button (221) may include a push button body (221a) having a laser output port (H221) through which a central laser is output, a plurality of coupling protrusions (221b) located on the rear side of the push button body (221a), and a contact protrusion (221c) located on the rear side of the push button body (221a).
[0084] Accordingly, by means of the plurality of coupling protrusions (221b), the push button (221) can be stably coupled and positioned within the push button mounting hole (H12) of the protective cover part (12).
[0085] These coupling protrusions (221b) may be positioned on the rear portions of the push button body (221a) facing each other, for example, on the upper and lower portions, and may have the same structure.
[0086] The coupling protrusion (221b) of this example is coupled with a corresponding part located within the push button mounting hole (H12) of the protective cover part (12), thereby preventing the push button (202) from moving in a direction other than a predetermined direction (e.g., forward / backward direction) (X).
[0087] The contact protrusion (221c) can contact the laser operation button (222) depending on the position of the push button (221) and apply physical force to the laser operation button (222).
[0088] When the contact protrusion (221c) comes into contact with the laser operation button (222) and applies physical force to the laser operation button (222), the laser operation button (222) can be pushed in a predetermined direction (e.g., backward). Accordingly, the contact protrusion (221c) can perform the function of pushing the laser operation button (222) in a predetermined direction (e.g., backward).
[0089] These contact protrusions (221c) may be positioned on the rear portions of the push button body (221a) facing each other, for example, on the left and right sides, and may have the same structure. At this time, one of the plurality of contact protrusions (221c) may come into contact with the laser operation button (222) to push the laser operation button (222) in a predetermined direction.
[0090] This contact protrusion (221c) may be positioned on a protrusion that protrudes backward from the rear surface of the push button body (221a). Accordingly, the portion of the push button body (221a) where the contact protrusion (221c) is positioned may have a two-layer structure with a step. The movement distance of the contact protrusion (221c) may be further reduced by the protrusion length due to this protrusion.
[0091] The laser irradiation button (222) facing the contact protrusion (221c) can be located within the laser irradiation button mounting portion (D111) located in the front case body (11), as illustrated in FIG. 9.
[0092] As shown in Fig. 5, the laser irradiation button mounting portion (D111) may be provided with a protrusion (H111) into which a part of the laser irradiation button (222) can be inserted and protrude toward the rear.
[0093] The laser irradiation button (222) may be provided with a laser irradiation button body (2221), as shown in FIGS. 9 to 11, and a pair of coupling protrusions (222c) protruding outward from approximately the center portion of the laser irradiation button body (2221).
[0094] The laser irradiation button body (2221) may have an upper protrusion (222a) and a lower protrusion (222b) located at the upper and lower portions, respectively, facing each other on opposite sides.
[0095] At this time, the upper protrusion (222a) may be positioned slightly forward of the lower protrusion (222b) with the center portion where the coupling protrusion (222c) of the laser irradiation button (222) is located.
[0096] As shown in Fig. 11, the upper protrusion (222a) of the laser irradiation button (222) is positioned on the same line along the front-back direction (X) as the contact protrusion (221c) of the push button (221) located at the front, and can overlap with the contact protrusion (221c) while being spatially separated from it.
[0097] The upper protrusion (222a) can change its position by coming into contact with the contact protrusion (221c) according to the change in the position of the contact protrusion (221c) due to the change in the distance of the push button (221).
[0098] The lower protrusion (222b) can be positioned opposite the upper protrusion (222a), and can control the state of the laser irradiation switch (223) by moving its position in the opposite direction to the upper protrusion (222a) according to the movement of the position of the upper protrusion (222a).
[0099] In addition, the laser irradiation button (222) may further include a switch protrusion (222b1) protruding toward the rear case (102) on the rear side of the lower protrusion (222b) of the laser irradiation button (222), i.e., toward the laser irradiation switch (223) (see FIG. 10).
[0100] In this example, the switch protrusion (222b1) can be inserted into a protrusion (H111) (see FIG. 5) in the laser irradiation button mounting portion (D111) and protrude in a rearward direction, for example, toward the rear case (102).
[0101] The switch protrusion (222b1) of the laser irradiation button (222) can be brought into contact with the laser irradiation switch (223) or released from contact depending on the position of the push button (221) (see Fig. 10).
[0102] When the state of the laser irradiation button (222) is an operating state in which the contact is released, the switch protrusion (222b1) can be positioned apart from the laser irradiation switch (223).
[0103] Accordingly, a pair of coupling protrusions (222c) of the laser irradiation button (222) can be inserted into a pair of coupling holes (H112) located in the laser irradiation button mounting portion (D111), as illustrated in FIG. 9, respectively, and in this case, the laser irradiation button (222) can be positioned rotatably in the laser irradiation button mounting portion (D111). At this time, the laser irradiation button (222) can rotate in the forward and backward direction (X) with the coupling protrusions (222c) inserted into the coupling holes (H112) as the center.
[0104] When the push button (221) is moved backward by a physical force applied from the outside, the contact protrusion (221c) of the push button (221) can come into contact with the upper protrusion (222a) of the laser irradiation button (222) and then apply a physical force to the upper protrusion (222a).
[0105] By a physical force, the laser irradiation button (222) can be rotated in a rearward direction in which the force is applied around the coupling protrusion (222c), and by this rotational motion, the lower protrusion (222b) of the laser irradiation button (222) can be rotated in the opposite direction to the upper protrusion (222a) and moved in the forward direction.
[0106] In this way, the switch protrusion (222b1) of the lower protrusion (222b) of the laser irradiation button (222) can change its contact state with the laser irradiation switch (223) according to the positional movement of the lower protrusion (222b).
[0107] For example, when the switch protrusion (222b1) is in the initial state, i.e., when no physical force is applied to the push button (221), it can pass through the protrusion (H111) and contact the laser irradiation switch (223) located at the rear, thereby maintaining a state in which the laser irradiation switch (223) is turned on (see Fig. 10). Accordingly, the laser irradiation switch (223) can maintain the on state when in the initial state and output a signal corresponding to the on state.
[0108] However, when the lower protrusion (222b) rotates forward in the opposite direction to the upper protrusion (222a) by the operation of the push button (221), the switch protrusion (222b1) located on the lower protrusion (222b) can also move forward together with the lower protrusion (222b).
[0109] Accordingly, the switch protrusion (222b1) may be separated from the laser irradiation switch (223) that was maintaining the contact state, and thus the contact state with the laser irradiation switch (223) may be released. As a result, the switch protrusion (222b1) may not be able to turn on the laser irradiation switch (223), and the state of the laser irradiation switch (223) may change from an on state to an off state.
[0110] Accordingly, when a physical force is applied to the push button (221) and the push button (221) is operated in a set state, the laser irradiation switch (223) is turned off and can output a signal corresponding to the off state.
[0111] On the other hand, when the position of the push button (221) returns to the initial state, the force applied to the laser irradiation button (222) is released, so the laser irradiation button (222) also returns to the initial position, and the switch protrusion (222b1) can return to the initial state of turning on the laser irradiation switch (223).
[0112] In this way, the laser irradiation button (222) can rotate the upper protrusion (222a) and the lower protrusion (222b) in opposite directions around the coupling protrusion (222c) depending on whether the push button (221) is operated, and as a result, the contact state between the switch protrusion (222b1) of the lower protrusion (222b) and the laser irradiation switch (223) can change.
[0113] In this way, the laser irradiation switch (223), whose state is changed by the push button (221), is a switch for laser irradiation and can output a signal corresponding to the current state to the laser blood collection module (40).
[0114] Therefore, the laser blood collection module (40) can control the operation for laser generation and irradiation when the state of the signal applied from the laser irradiation switch (223) changes from a non-operating state (e.g., on state) to an operating state (e.g., off state).
[0115] The safety switch unit (203) may be for laser generation and irradiation together with the contact detection switch unit (202).
[0116] This safety switch unit (203) can change its state by a physical force applied from the outside by the user's action.
[0117] For example, the safety switch unit (203) may also be equipped with a safety switch button (231) whose state changes depending on the user's action, for example, the distance from the laser output module unit (403), and a safety switch (232) whose state changes depending on the state of the safety switch button (231).
[0118] The safety switch button (231) can be located in the safety button mounting hole (H113) located in the case body (11) of the front case (101).
[0119] Accordingly, when a user presses the safety switch button (231), the safety switch (232) can be operated by the physical force applied through the safety switch button (231) and maintained in an operating state (e.g., on state), and when the force applied to the safety switch button (231) is removed, the safety switch (232) can be maintained in an initial non-operating state (e.g., off state).
[0120] Accordingly, the safety switch (232) can output a signal corresponding to its status to the laser blood collection module (40).
[0121] The laser blood collection and blood sugar measurement device (1) of this example can perform laser generation and irradiation operations only when both the safety switch unit (203) and the contact detection switch unit (202) remain in an operating state for the safety of the user.
[0122] Accordingly, when the user operates the safety switch button (231) to keep the safety switch (232) in an operating state (e.g., on state), and then presses the push button (221) against the skin of the subject from whom blood is to be drawn, and then applies a force greater than a set value to the push button (221) so that the laser irradiation switch (223) is in an operating state (e.g., off state), the laser blood collection module (40) starts operating so that a laser generation operation for blood collection can be performed.
[0123] The menu selection switch (204) may be used to select the operation mode of the laser blood collection and blood sugar measurement device (1).
[0124] This menu selection switch unit (204) may be equipped with a menu selection switch button (241) whose state changes according to the user's action and a menu selection switch (242) whose state changes according to the state of the menu selection switch button (241).
[0125] The menu selection switch button (241) can be mounted in the mounting hole (H121) of the rear case (102) and can be controlled by the user to change the state of the menu selection switch (242) to an operating state (e.g., on state) or an inoperative state (e.g., off state).
[0126] Accordingly, the user can operate the menu selection switch (242) using the menu selection switch button (241), and the menu selection switch (242) can output a signal of the operating status to the laser blood collection module (40).
[0127] For example, the operation mode of the laser blood collection and blood sugar measurement device (1) selectable by the menu selection switch unit (204) may include at least one of a laser blood collection mode, a blood sugar measurement mode, a memory mode, and a setting mode.
[0128] The laser blood collection mode is a mode that generates a laser for blood collection and irradiates the generated laser to the corresponding skin of the subject, and bleeding may occur due to perforation of the skin irradiated with the laser.
[0129] The blood sugar measurement mode may be a mode for performing a blood sugar measurement operation by applying blood to a blood sugar test strip inserted into a laser blood collection and blood sugar measurement device (1).
[0130] The memory mode may be a mode for reading desired blood sugar measurement data from among blood sugar measurement data generated through a blood sugar measurement operation and stored in a storage unit (406) and outputting the data to the information output unit (60).
[0131] The setting mode may be a mode for changing setting values determined by the user's selection actions, etc.
[0132] At this time, the blood collection mode, blood sugar measurement mode, and memory mode can be sequentially changed in a set order (e.g., blood collection mode->blood sugar measurement mode->memory mode) whenever the menu selection switch (204) is operated by the user.
[0133] On the other hand, when the operation mode of the laser blood collection and blood glucose measurement device (1) is the blood collection mode, blood glucose measurement mode, or memory mode, and the menu selection switch unit (204) is operated by the user for a set time (e.g., 3 seconds), the operation mode of the laser blood collection and blood glucose measurement device (1) can be moved to the setting mode.
[0134] The menu movement switch section having the first movement switch section (205) and the second movement switch section (206) enables movement to the location of the desired menu or information among the menus or information displayed on the information output section (60).
[0135] The movement directions by the operation of the first movement switch unit (205) and the second movement switch unit (206) may be opposite to each other. For example, the first movement switch unit (205) may be for moving forward, to the left, or upward based on the current position, and the second movement switch unit (206) may be for moving backward, to the right, or downward based on the current display position.
[0136] These first movement switch unit (205) and second movement switch unit (206) may each be provided with a first movement switch button (251) and a second movement switch button (261) whose states change according to the user's operation, and a first movement switch (252) and a second movement switch (262) whose states change according to the states of the movement switch buttons (251, 261).
[0137] The first and second movement switch buttons (251, 261) can be mounted in the mounting holes (H121) of the rear case (102) and can be controlled by the user to change the state of the first movement switch (252) and the second movement switch (262) to an operating state (e.g., an on state) or an inoperative state (e.g., an off state), respectively.
[0138] By means of these first and second moving switch units (205, 206), the user can select a desired menu or data from among the menus or data of the laser blood collection and blood glucose measurement device (1).
[0139] For example, the first and second moving switch units (205, 206) can select a fasting state when measuring blood sugar.
[0140] Additionally, the first and second moving switch units (205, 206) select the intensity level of the laser corresponding to each blood sampler and store it in the storage unit (406).
[0141] The reset switch (207) may be used to reset the status of the laser blood collection and blood glucose measurement device (1) to an initial state.
[0142] On the lower side of the front case body (11), a reset switch operating port (H114) may be positioned facing the reset switch (207) to operate the reset switch (207).
[0143] Accordingly, the user can operate the reset switch (207) by inserting a pin or the like suitable for the size of the reset switch operating portion (H114) into the reset switch operating portion (H114).
[0144] Due to this, the reset switch (207) can apply a signal of an operating state (e.g., an on state) to the laser blood collection module (40). Accordingly, the laser blood collection module (40) can change the variables of the laser blood collection and blood glucose measurement device (1) to initial values according to the signal applied from the reset switch (207).
[0145] The battery module (30) may be a module for supplying power required for the operation of the laser blood collection and blood glucose measurement device (1).
[0146] Such a battery module (30) may be equipped with a battery (31) and a battery charging unit (32) as already described.
[0147] The battery (31) may be a power supply unit for supplying power required for the operation of the laser blood collection and blood glucose measurement device (1), and the battery charging unit (32) may receive external power applied from the outside and perform a charging operation of the battery (31).
[0148] In this example, the battery charging unit (32) can control the charging operation of the battery (31) by receiving external power input through an input / output terminal such as a USB (universal serial bus) terminal.
[0149] Accordingly, when a power supply terminal is inserted into the terminal insertion port (H124) of the rear case (102) and external power is supplied to the battery charging unit (32), the battery charging unit (32) can perform a charging operation of the battery (31) using the supplied external power.
[0150] The laser blood collection module (40) is for generating a laser for blood collection from a subject and irradiating it externally, i.e., toward the subject.
[0151] As illustrated in FIGS. 4 to 6, such a laser blood collection module (40) may include, for example, a circuit board (401), a capacitor module (402) located on the circuit board (401), a laser output module (403) located on the circuit board (401) and connected to the capacitor module (402), a lens protection unit (404) located in front of the laser output module (403), an operation control unit (405) connected to the capacitor module (402) and the information output unit (60), a storage unit (406) connected to the operation control unit (405), and a communication unit (407) connected to the operation control unit (405).
[0152] The circuit board (401) may be a printed circuit board such as a hard printed circuit board (HPCB), and components, electrical components, electronic components, wiring, etc. for the operation of the laser blood collection module (40) may be mounted or printed on it.
[0153] Accordingly, various switches (212, 223, 232, 242, 252, 262, 207) are also located on the circuit board (401) and can be electrically connected to the corresponding components (e.g., 405) using wiring, etc.
[0154] The capacitor module unit (402) applies a voltage of a set size to the laser output module unit (403) under the control of the operation control unit (405) so that a laser of the corresponding intensity can be excited and output.
[0155] This capacitor module unit (402) may include a capacitor charging unit (402a) (see FIG. 21) connected to an operation control unit (405) and a capacitor unit (402b) connected to the capacitor charging unit (402a).
[0156] As illustrated in Fig. 21, the capacitor charging unit (402a) controls the operation of the capacitor unit (402b) according to a driving signal applied from the operation control unit (405) so that the capacitor unit (402b) can be charged with a voltage of a predetermined size.
[0157] Accordingly, the capacitor charging unit (402a) can control the charging and discharging operations of the capacitor unit (402b) by applying a control signal of a predetermined size to the capacitor unit (402b) according to the control signal applied from the operation control unit (405).
[0158] The capacitor unit (402b) operates under the control of the capacitor charging unit (402a) to perform voltage charging and discharging operations, and then applies a charging voltage to the laser output module unit (403) under the control of the capacitor charging unit (402a) to cause the laser to be output from the laser output module unit (403).
[0159] This capacitor section (402b) may be provided with at least one capacitor (421) located at a corresponding position of the circuit board (401), as illustrated in FIGS. 4 to 6.
[0160] When there are multiple capacitors (421), the multiple capacitors (421) can be arranged in series at corresponding locations on the circuit board (401).
[0161] A battery (31) may be positioned above at least one capacitor (421). In this way, in the present example, since the battery (31) is positioned above the capacitor portion (402b) instead of directly on the circuit board (401), the mounting space for the battery (31) on the circuit board (401) is reduced, and thus the size of the circuit board (401) can be reduced.
[0162] In this example, the charging voltage of the capacitor section (402b) may be approximately 300 V to 360 V.
[0163] When laser irradiation is performed for blood collection, the charging voltage of the capacitor unit (402b) can be determined according to the laser intensity level selected by the user (one of the first to eighth levels). This selection operation for the laser intensity level can be performed using the movement switch unit (205, 206).
[0164] For example, if the intensity level of the laser selected by the user is the first level, the charging voltage of the capacitor unit (402b) may be 306 V, and if the intensity level of the laser selected by the user is the eighth level, the charging voltage of the capacitor unit (402b) may be 360 V.
[0165] In this way, the magnitude of the charging voltage of the capacitor unit (402b) may be determined depending on the magnitude of the intensity level of the selected laser. Accordingly, the operation control unit (405) may determine the intensity level of the selected laser and control the operation of the capacitor charging unit (402a) so that the capacitor unit (402b) is charged with a voltage corresponding to the selected intensity level.
[0166] In this way, the size of the charging voltage of the capacitor unit (402b) applied to the laser output module unit (403) may vary depending on the size of the intensity level of the laser.
[0167] The laser output module unit (403) can generate and output a laser of a corresponding intensity using the charging voltage applied from the capacitor unit (402b), and may be a laser output device.
[0168] Accordingly, the size of the laser intensity output from the laser output module unit (403) can be determined according to the size of the applied charging voltage, and for example, as the size of the applied charging voltage increases, the size of the generated laser intensity can increase.
[0169] This laser output module part (403), as shown in FIGS. 12 to 15, includes a laser medium part (431), a first laser mirror part (431a) and a second laser mirror part (431b) positioned respectively at both ends of the laser medium part (431), a lamp part (432) positioned parallel to the laser medium part (431) and spaced apart from the laser medium part (431), a barrel (433) containing the laser medium part (431) and the lamp part (432), a first reflector (4341) and a second reflector (4342) positioned respectively at both ends of the barrel (433), a first holder part (4351) and a second holder part (4352) positioned respectively at both ends of the barrel (433) containing the laser medium part (431) and the lamp part (432) to stably fix the position of the barrel (433), and 1 and A lens unit (436) may be provided located in one of the second holder units (4351, 4352), for example, the first holder unit (4351).
[0170] In this example, the laser medium unit (431) can generate and output an Er-YAG (Yttrium Aluminum Garnet) laser according to the intensity of light output from the lamp unit (432).
[0171] For example, the laser output from the laser output module (403) may be a solid-state laser that oscillates at a wavelength of approximately 2,940 nm.
[0172] Accordingly, the laser medium (431) can generate and output an ultra-small erbium:YAG (Yttrium Aluminum Garnet) laser.
[0173] For example, the laser output from the laser output module (403) according to the present example may have a wavelength of approximately 2,940 nm.
[0174] Therefore, the laser medium (431) is a solid laser medium that oscillates at a wavelength of 2,940 nm, and can use erbium YAG.
[0175] The shapes of the two ends of the laser medium (431) may be different from each other.
[0176] For example, one end of the laser medium (431) adjacent to the skin of the subject of the blood collection may be a flat surface or a curved surface, and the other end of the laser medium (431) located opposite the one end may be a curved surface. When at least one of the one end and the other end of the laser medium (431) is a curved surface, the corresponding end may have a concave shape, and thus, the corresponding curved surface of the laser medium (431) may have a convex shape that protrudes outward.
[0177] Due to this, the radius of curvature of one end of the laser medium portion (431) may be greater than the radius of curvature of the other end of the laser medium portion (431).
[0178] For example, the radius of curvature of the other end of the laser medium (431) may be 500 mm to 1500 mm, and preferably 1000 mm.
[0179] In addition, when one end of the laser medium (431) is a curved surface, the radius of curvature of one end may be greater than the radius of curvature of the other end, and when one end of the laser medium (431) is a flat surface, the radius of curvature may be infinite.
[0180] A first laser mirror part (431a) and a second laser mirror part (431b) formed by applying a reflective material may be positioned at both ends of the laser medium part (431).
[0181] In this example, the laser medium (431) may have a length (L431) of approximately 3 cm to 4 cm and a diameter (D431) of approximately 2.8 mm to 3.3 mm. In addition, the erbium YAG may use a material doped with 50% Er (a specific ratio between 49% and 51%) in the base crystal of the YAG.
[0182] In this example, the laser medium part (431) can output energy of a size proportional to the intensity of light output from the lamp part (432).
[0183] Accordingly, the size of the diameter activated in the diameter of the laser medium portion (431) may vary depending on the intensity of the light output from the lamp portion (431), and thus, the size of the diameter (i.e., beam diameter) of the laser beam (LB431) output from the laser medium portion (431) may vary within the size of the diameter of the laser medium portion (431).
[0184] For example, the size of the beam diameter (D431a) of the laser beam (LB431) output from the laser medium portion (431) may be 80% to 95% of the diameter (D431) of the laser medium portion (431), and more specifically, 87% to 89%.
[0185] For example, the diameter of the laser medium (431) may be 3 mm, and the beam diameter (D431a) of the laser beam (LB431) may be 2.5 mm to 2.9 mm.
[0186] Additionally, the laser medium (431) can output a laser with low output energy, for example, can output a laser with energy of 40 mJ to 180 mJ.
[0187] As already described, the first laser mirror section (431a) and the second laser mirror section (431b) may be reflective sections formed by applying a reflective material, such as a mirror manufacturing material used when manufacturing a mirror, such as silver nitrate, to each end of the laser medium section (431).
[0188] As already described, the curvature radii of the two ends of the laser medium portion (431) where the first laser mirror portion (431a) and the second laser mirror portion (431b) are respectively positioned may be different from each other, and thus, the curvature radius of the first laser mirror portion (341a) positioned at one end of the laser medium portion (431) may also be larger than the curvature radius of the second laser mirror portion (431b).
[0189] Therefore, the first laser mirror unit (431a) and the second laser mirror unit (431b) can reflect the laser output from the laser medium unit (431) back toward the laser medium unit (431).
[0190] In particular, the other end of the laser medium portion (431) on which the laser is irradiated may have a convex shape in which the radius of curvature is smaller than the radius of curvature of the other end, rather than the other end of the laser medium portion (431). In this case, the laser output to the other end of the laser medium portion (431) may be reflected back toward the laser medium portion (431) by the second laser mirror portion (431b).
[0191] In addition, the reflectivity of the first laser mirror unit (431a) and the reflectivity of the second laser mirror unit (431b) are different from each other, so that the reflectivity of the first laser mirror unit (431a) located on the side where the laser is output to the outside may be lower than the reflectivity of the second laser mirror unit (431b).
[0192] For example, the reflectivity of the first laser mirror unit (431a) may be 80% to 90%, and the reflectivity of the second laser mirror unit (431b) may be 100%.
[0193] Accordingly, the laser irradiated toward the rear side of the laser medium (431), that is, the laser output in the opposite direction to the laser irradiation direction, can be reflected by the second laser mirror (431b) and incident toward the laser medium (431), and the laser irradiated toward the front side of the laser medium (431), that is, the laser output in the same direction as the laser irradiation direction, can be reflected by the first laser mirror (431a) except for some and incident toward the laser medium (431).
[0194] At this time, some of the laser that is not reflected by the first laser mirror (431a) may pass through the lens unit (436) and be irradiated toward the skin of the subject of blood collection, thereby allowing a blood collection operation to be performed according to the laser irradiation.
[0195] The lamp unit (432) is for supplying energy to the laser medium unit (431) and may be a flash lamp that generates a flash of a predetermined size (e.g., 100 W).
[0196] Accordingly, the lamp unit (432) can receive a voltage of the corresponding size from the capacitor unit (402b) and generate a flash of a size corresponding to the size of the applied voltage.
[0197] This lamp unit (432) may be a glass tube having a cylindrical shape that maintains a vacuum state, and the glass tube may be filled with a rare gas of 400 mmHg to 700 mmHg.
[0198] In this state, when a trigger current is applied to the electrode of the lamp unit at a set time interval (e.g., 40 mm to 45 mm), a flash of approximately 80 to 100 WS can be induced by discharge.
[0199] Terminals (T432) for receiving signals may be positioned at each end of the lamp unit (432). At this time, the shape of each terminal (T432) may have an approximate 'ㄱ' shape. The terminals (T432) positioned on both sides of the lamp unit (432) may be positioned in a left-right reversed manner.
[0200] The tube (433) has an empty space inside which a laser medium portion (431) and a lamp portion (432) are positioned and can extend in a predetermined direction (e.g., forward and backward direction) (X). The tube (433) may have a cylindrical shape with a circular cross-section, but is not limited thereto and may have a columnar shape with a polygonal cross-section.
[0201] These tubes (433) may include a metal material such as aluminum, and may be made of aluminum, for example.
[0202] In this example, instead of coating the inner surface of the barrel (433) with a reflective material, a polishing process may be performed. As a result, the inner surface of the barrel (433) may have a plurality of uneven surfaces in which the grooves and the protrusions are located.
[0203] Accordingly, the inner surface of the barrel (433) may be a polished surface, and the outer surface of the barrel, i.e., the outer surface located opposite the inner surface and exposed to the outside, may be a non-polished surface that is not subjected to polishing. Accordingly, the surface roughness of the inner surface of the barrel (433) may be different from the surface roughness of the outer surface of the barrel (433), and for example, the surface roughness of the inner surface of the barrel (433) may be smaller than the surface roughness of the outer surface of the barrel (433).
[0204] By the polishing treatment performed on the barrel (433), the reflectivity of the inner surface of the barrel (433) may be greater than the reflectivity of the outer surface of the barrel (433).
[0205] In this way, even if the reflectivity of the inner surface of the barrel (433) is increased by polishing the inner surface, the reflectivity within the barrel (433) of this example may decrease compared to the comparative example in which the reflective layer is located within the barrel (433).
[0206] For example, in the present example, due to the polishing process on the inner wall of the barrel (433), the energy of light output from the lamp unit (432) of the present example may be reduced by approximately 20% compared to the comparative example in which a reflective material is applied to the inner wall of the barrel (433).
[0207] In this way, the present example can decrease, rather than increase, the intensity of the laser beam irradiated toward the skin of the subject of the blood collection. To this end, as previously described, the present example polishes the inner surface of the tube (433) so that the reflectivity of the light output from the lamp unit (432) can be reduced compared to when a reflective material is applied, thereby reducing the intensity of the laser beam output from the laser medium unit (431) of the present example.
[0208] Additionally, in the present example, the inner surface of the barrel (433) is simply polished, so there is no separate reflective layer on the barrel (433). Therefore, the barrel (433) of the present example can be formed of a single layer.
[0209] On the other hand, in the case of a comparative example in which a reflective layer is provided inside the barrel (433), a mirror portion having the same shape (e.g., cylindrical) as the internal shape of the barrel (433) and having a mirror manufacturing material applied thereto is inserted into the inside of the barrel (433) so that the internal surface of the barrel (433) and the external surface of the mirror portion can be positioned to be in contact with each other.
[0210] In this comparative example, the optical tube (433) does not perform any laser reflection function at all, and can only serve as a case that has a lamp unit and a laser medium unit inside. In addition, in this case, since a mirror unit must be additionally manufactured and installed, the manufacturing cost and manufacturing time of the laser output module unit (403) increase, and the problem of increased weight and size may also arise.
[0211] However, in the present example, since the case-functioning optical tube (433) also performs a reflection function, there is no need for a separate reflection layer such as a mirror. Accordingly, the manufacturing cost and manufacturing time of the laser output module (403) are reduced, and the size and weight of the laser output module (403) can also be reduced.
[0212] The length of the optical tube (433) of this example may be shorter than the lengths of the laser medium portion (431) and the lamp portion (432) inserted therein, and thus, both ends of the laser medium portion (431) and both ends of the lamp portion (432) may be exposed to the outside of the optical tube (433) through the open ends of the optical tube (433).
[0213] Inside the optical tube (433) of this example, the laser medium section (431) and the lamp section (432) that outputs light to the laser medium section (431) can be arranged in a close coupling configuration in which they are positioned adjacent to each other and in parallel.
[0214] The diameter (D433) of this tube (433) may be 8 mm to 9 mm, and the thickness (T433) may be 1.8 mm (t) to 2.2 mm (t).
[0215] If the diameter (D433) of the barrel (433) is less than 8 mm, the laser medium portion (431) and the lamp portion (432) of a predetermined size cannot be stably positioned inside it, and if the diameter (D433) of the barrel (433) exceeds 9 mm, the light reflection efficiency by the barrel (433) decreases and the volume of the laser output module portion (403) may increase unnecessarily.
[0216] In addition, if the thickness (T433) of the barrel (433) is less than 1.8 mm, it may have a negative effect on the polishing operation of the barrel (433), and if the thickness (T433) of the barrel (433) exceeds 2.2 mm, the heat dissipation effect generated from the barrel (433) may be reduced, which may cause the barrel (433) to overheat. The first reflector (4341) and the second reflector (4342) may be respectively positioned at the open ends of the barrel (433) having an empty space therein.
[0217] Accordingly, both ends of the open tube (433) can be blocked by the first reflector (4341) and the second reflector (4342), respectively.
[0218] At this time, the diameters of the first reflector (4341) and the second reflector (4342) may be the same, and the diameters of the first reflector (4341) and the second reflector (4342) may be the same as the diameter of the barrel (433).
[0219] In each of the first reflector (4341) and the second reflector (4342), the inner surface, i.e., the surface adjacent to the laser medium portion (431) and the lamp portion (432), may be a polished surface that has been polished, whereas the outer surface, i.e., the surface located opposite the inner surface, may be a non-polished surface that has not been polished.
[0220] Accordingly, the surface roughness of the inner surface of each reflector (4341, 4342) may be different from the surface roughness of the outer surface of each reflector (4341, 4342), and for example, the surface roughness of the inner surface of each reflector (4341, 4342) may be smaller than the surface roughness of the outer surface of each reflector (4341, 4342). Accordingly, due to the polishing treatment performed on each reflector (4341, 4342), the reflectivity of the inner surface of each reflector (4341, 4342) may be greater than the reflectivity of the outer surface of each reflector (4341, 4342).
[0221] The polishing degree of the inner surface of each reflector (4341, 4342) may be less than the polishing degree of the inner surface of the barrel (433), and accordingly, the reflectivity of the inner surface of each reflector (4341, 4342) may be less than the reflectivity of the inner surface of the barrel (433).
[0222] For example, the reflectivity of each reflector (4341, 4342) for light having a wavelength of 625 nm may be 85% to 95%.
[0223] By these first and second reflectors (4341, 4342), the light of the lamp unit (432) that is output toward the laser medium unit (431) and is to be output to the outside through both ends of the open tube (433) is reflected back into the tube (433) by the first reflector (4341) and the second reflector (4342) and can be incident toward the laser medium unit (431).
[0224] Accordingly, the light within the optical tube (433) output from the lamp unit (432) can be reflected by the first reflector (4341) and the second reflector (4342) and incident toward the laser medium unit (431), and the amount of light incident toward the laser medium unit (431) can be increased by the repeated reflection operation by the first reflector (4341) and the second reflector (4342).
[0225] In this way, the laser blood collection and blood sugar measurement device (1) of the present example can increase the amount of light incident toward the laser medium portion (431) by utilizing the reflection function using the first reflector (4341) and the second reflector (4342). Therefore, the laser blood collection and blood sugar measurement device (1) of the present example can prevent the phenomenon of insufficient light incident toward the laser medium portion (431) even without applying a reflective material to the inner wall of the tube (433), and can instead increase the amount of light incident toward the laser medium portion (431).
[0226] Therefore, even compared to a case where a reflective material is applied inside the tube (433), in the case of the laser blood collection and blood sugar measurement device (1) of the present example, the amount of light incident on the laser medium portion (431) is not significantly reduced, so that the operation of the laser medium portion (431) can be performed stably.
[0227] In addition, instead of applying a reflective material to the inside of the tube (433), the laser blood collection and blood glucose measurement device (1) of the present example polishes the inner wall of the tube (433) and mounts a first reflector (4341) and a second reflector (4342) on both ends of the open tube (433), so that the cost and time for increasing the reflectivity of the tube (433) can be greatly reduced compared to when applying a reflective material to the inner wall of the tube (433).
[0228] In addition, when applying a reflective material, the thickness of the applied material varies depending on the location, so the reflectivity of the barrel (433) may vary depending on the location.
[0229] However, since the laser blood collection and blood glucose measurement device (1) of this example only needs to perform the polishing process of the inner wall of the tube (433) and the installation process of the first reflector (4341) and the second reflector (4342) in which there is little difference in the uniformity of the process depending on the location, there may be little difference in the reflectivity of the tube (433) depending on the location. As a result, the reflection efficiency of the laser blood collection and blood glucose measurement device (1) of this example is improved, and uniform light can be incident on the lamp unit (432).
[0230] These first reflector (4341) and second reflector (4342) may have different structures.
[0231] For example, the first reflector (4341) and the second reflector (4342) may have a circular planar shape identical to the cross-sectional shape of the barrel (433) obtained by cutting along the short axis direction.
[0232] Accordingly, the diameters of the first reflector (4341) and the second reflector (4342) can be determined according to the inner diameter, which is the size of the short axis direction of the barrel (433), and, for example, can be equal to or smaller than the inner diameter of the barrel (433).
[0233] In this example, the entire laser medium (431) may be positioned within an internal space formed by the first reflector (4341) and the second reflector (4342), which are respectively positioned on the open sides of the tube (433). As a result, at least one of the two sides of the laser medium (431) may be positioned within the internal space and not be exposed to the outside, i.e., may not be positioned so as to penetrate both the first reflector (4341) and the second reflector (4342).
[0234] At this time, the lamp part (432) may also be positioned so that at least one side of the two sides is located within the internal space, similar to the laser medium part (431), and is not exposed to the outside.
[0235] An example of the structure of the first reflector (4341) and the second reflector (4342) for this purpose is as follows. The first reflector (4341) may be provided with a first through hole (H4341), a second through hole (H4342), and a third through hole (H4343) for dissipating heat, through which the corresponding portions (e.g., one side portion) of the laser medium portion (431) and the lamp portion (432) can pass, as shown in FIGS. 14 and 15, respectively.
[0236] At this time, the arrangement of the first through hole (H4341) and the second through hole (H4342) can be determined according to the arrangement of the laser medium part (431) and the lamp part (432) within the tube (433).
[0237] For example, the laser medium portion (431) and the lamp portion (432) can be arranged side by side and spaced apart from each other along a direction (e.g., left-right direction) (Y) intersecting the forward-backward direction (X), and thus, the first through hole (H4341) and the second through hole (H4342) can also be arranged side by side and spaced apart from each other along the corresponding direction (Y direction).
[0238] By means of the first reflector (4341) and the second reflector (4342), as shown in FIGS. 16 and 17, one side of the laser medium portion (431) and one side of the lamp portion (432) protruding outward from the first side of the barrel (433) can be inserted into the first through hole (H4341) and the second through hole (H4342) of the first reflector (4341) located adjacent to each of the two ends of the barrel (433) and maintained in a penetrating state.
[0239] The third through hole (H4343) can be positioned apart from the first and second through holes (H4341, H4342) in a location where the first and second through holes (H4341, H4342) are not positioned.
[0240] The diameter of the third through hole (H4343) may be much smaller than the diameters of the first and second through holes (H4341, H4342). Therefore, the heat generated in the corresponding reflector (4341, 4342) can be dissipated to the outside more easily by the third through hole (H4343).
[0241] On the other hand, as illustrated in FIGS. 16 and 17, the other side of the lamp portion (432) excluding the laser medium portion (431) and the terminal (T432) may not protrude outward from the second side of the barrel (433) (i.e., the side of the barrel (433) facing the first side on the opposite side of the first side).
[0242] Accordingly, for this purpose, unlike the first reflector (4341), the second reflector (4342) may not have first and second penetration holes (H4341, H4342) for the laser medium section (431) and the lamp section (432) to completely penetrate the second reflector (4342).
[0243] Instead, as an example, the second reflector (4342) may have a fixing groove (P4341, P4342) or a fixing protrusion on the inner surface facing the laser medium portion (431) and the lamp portion (432) to fix the positions of the laser medium portion (431) and the lamp portion (432), respectively.
[0244] At this time, a terminal hole (H432) for discharging the terminal (T432) may be located within the fixed groove (P4341) where the lamp part (432) is located.
[0245] Due to this, the outer surface of the second reflector (4342) located on the opposite side of the inner surface may be completely blocked except for the part where the terminal hole (H432) is located, as shown in FIG. 15.
[0246] The first reflector (4341) and the second reflector (4342) of this example may contain a metal material with high reflectivity and may be made of aluminum.
[0247] The first holder part (4351) and the second holder part (4352) can be positioned on each side of the barrel (433) containing the laser medium part (431) and the lamp part (432).
[0248] In this example, the first holder part (4351) may be a holder part located on the first side of the barrel (433), and the second holder part (4352) may be a holder part located on the second side of the barrel (433) located on the opposite side of the first side.
[0249] Accordingly, a space surrounded by the barrel (433), the first holder part (4351), and the second holder part (4352) may exist, and this space may be a receiving space in which the laser medium part (431) and the lamp part (432) located inside the barrel (433) are located and received.
[0250] These first holder portion (4351) and second holder portion (4352) are intended to stably fix the position of the barrel (433) containing the laser medium portion (431) and the lamp portion (432).
[0251] In this example, the first holder portion (4351) and the second holder portion (4352) may have different structures.
[0252] For example, the first holder part (4351) and the second holder part (4352) may each be provided with a holder part body (4511), a barrel insertion groove (D4511) located in the holder part body (4511) and into which a corresponding end of a barrel (433) is inserted, a terminal through-hole (H4512) located in the barrel insertion groove (D4511) of the holder part body (4511) and through which a corresponding terminal (T432) of the lamp part (432) passes, and a terminal groove (D4513) located in the holder part body (4511) and into which a terminal (T432) passing through the terminal through-hole (H4512) is inserted.
[0253] In this example, the first holder part (4351) may additionally include a first insertion part (H4511) positioned within the barrel insertion groove (D4511) and into which the corresponding side of the laser medium part (431) exposed externally from the barrel (433) is inserted, and a second insertion part (D4512) positioned within the barrel insertion groove (D4511) and into which the corresponding side of the lamp part (432) exposed externally from the barrel (433) is inserted.
[0254] The holder body (4511) has a set thickness and may have a roughly semi-elliptical flat shape.
[0255] The first insertion portion (H4511) of the first holder portion (4351) into which the laser medium portion (431) is inserted may have a hole shape that completely penetrates the corresponding portion of the barrel insertion groove (D4511).
[0256] Due to this, one side of the laser medium portion (431) protruding outward from the tube (433) can be partially inserted and positioned into the first insertion portion (H4511) of the first holder portion (4351).
[0257] In the first holder portion (4351), a portion of the second insertion portion (D4512) excluding the terminal through hole (H4512) may have a structure in which a predetermined thickness is dug into the bottom surface of the barrel insertion groove (D4511). Accordingly, the bottom surface of the second insertion portion (D4512) and the bottom surface of the barrel insertion groove (D4511) may be positioned at different heights, thereby having a stepped structure.
[0258] Accordingly, the first insertion portion (H4511) of the first holder portion (4351) where the laser medium portion (431) is positioned can be positioned at a position facing the first through-hole (H4341) of the first reflector (4341) on the opposite side of the first through-hole (H4341), and the second insertion portion (D4512) of the first holder portion (4351) where the lamp portion (432) is positioned can be positioned at a position facing the second through-hole (H4342) of the first reflector (4341) on the opposite side of the second through-hole (H4342). Accordingly, one side of the laser medium portion (431) protruding outward from the barrel (433) can be positioned by penetrating the first through hole (H4341) of the first reflector (4341) and then being inserted into the first insertion portion (H4511) located in the first holder portion (4351), and the other side can be positioned within the corresponding fixing groove (P4341) of the second reflector (4342).
[0259] In the case of the lamp part (432), one side of the lamp part (432) protruding outward from the barrel (433) can be positioned by passing through the second through hole (H4342) of the first reflector (4341) and then being inserted into the second insertion part (D4512) located in the first holder part (4351), and the other side can be positioned within the corresponding fixing groove (P4342) of the second reflector (4342).
[0260] The terminal groove (D4513) may be located on the outer side of the holder body (4511), that is, on the opposite side of the inner side adjacent to the side of the barrel (433). This terminal groove (D4513) may extend along one direction of the holder body (4511).
[0261] Accordingly, each terminal (T432) located on both sides of the lamp unit (432) can pass through the terminal through hole (H4512) and be positioned within the corresponding terminal groove (D4513). In this way, since the terminal (T432) is inserted and positioned within the terminal groove (D4513), the signal required for the operation of the lamp unit (432) can be stably supplied without the risk of disconnection.
[0262] Accordingly, as illustrated in FIG. 13, the laser medium unit (431) and the lamp unit (432) can be positioned in a receiving space surrounded by the barrel (433) and the first and second holder units (4351, 4352), and, except for the terminal (T431) of the lamp unit (432), the laser medium unit (431) and the lamp unit (432) can not be exposed to the outside of the receiving space. Therefore, the laser medium unit (431) and the lamp unit (432) received inside the laser output module unit (403) can be more safely protected from the external environment.
[0263] In this example, unlike the second holder part (4352), the first holder part (4351) may further include a lens part insertion port (H4513) into which the lens part (436) is inserted and positioned.
[0264] As shown in FIGS. 14 and 15, the lens insertion port (H4513) can be located in a portion of the first holder portion (4351) where the insertion portion (H4511) is located.
[0265] Accordingly, the lens insertion port (H4513) may be positioned in front of the first insertion portion (H4511) and connected to the first insertion portion (H4511), and the inner diameter (D45a) of the first insertion portion (H4511), which is a hole, may be smaller than the inner diameter (D45b) of the lens insertion port (H4513).
[0266] Accordingly, as illustrated in Fig. 16, the lens unit (436) located in front of the laser medium unit (431), i.e., at one end of the laser medium unit (431), can be positioned by being seated in the lens unit insertion unit (H4513) located in the first holder unit (4351), which is the corresponding holder unit. At this time, due to the difference in size between the inner diameters (D45a, D45b) of the first insertion unit (H4511) and the lens unit insertion port (H4513), the lens unit (436) and the laser medium unit (431) can be positioned to be spaced apart by a predetermined distance.
[0267] The lens unit (436) may be provided with, for example, a lens (4361) positioned at a predetermined distance from the laser medium unit (431) and facing the laser medium unit (431), as shown in FIGS. 14 and 15, and a lens holder (4362) in which the lens (4361) is mounted and fixed.
[0268] As already described, the lens part (436) is positioned in the lens part insertion part (H4513) of the first holder part (4351) and can be positioned in front of the laser medium part (431) and spaced apart from the laser medium part (431) by a set distance.
[0269] Accordingly, the lens insertion portion (H4513) into which the lens portion (436) is inserted and mounted can be located on the outer side of the first holder portion (4351) adjacent to the skin of the subject of blood collection and can be connected to the first insertion portion (H4511) of the first holder portion (4351).
[0270] The center of the lens (4361) of the lens unit (436) may be positioned on the same virtual line as the center of the laser medium unit (431), for example, on the optical axis, and spaced apart by a set distance, as shown in FIG. 16.
[0271] At this time, the focal length of the lens (436) can be determined according to the distance (D436) between the lens (4361) and the laser medium (431). For example, the distance (D10) between the lens (4361) and the laser medium (431) can be 10 mm to 15 mm. The distance (D10) can be the distance between the lens (4361) and the first laser mirror (431a) coated on the adjacent laser medium (431).
[0272] In this example, the focal length (L20) of the lens (4361) may be 11 mm to 16 mm.
[0273] This lens section (436) is for focusing the laser generated and output from the laser medium section (431) and outputting it in a desired direction.
[0274] The lens (4361) may be a convex lens, as illustrated in FIG. 19, so that the first surface (e.g., front surface) of the lens (4361) adjacent to the skin of the subject of blood collection and positioned in the direction of laser emission and the second surface (e.g., rear surface) of the lens (4361) opposite the first surface and facing the laser medium (431) may both be convex surfaces.
[0275] At this time, the radius of curvature (e.g., first radius of curvature) (R1) of the first surface (e.g., front surface) of the lens (4361) and the radius of curvature (e.g., second radius of curvature) (R2) of the second surface (e.g., rear surface) of the lens (4361) may be different from each other. For example, the first radius of curvature (R1) may be smaller than the second radius of curvature (R2).
[0276] However, in an alternative example, the lens (4361) may be a flat lens, with a first surface of the lens (4361) being convex and a second surface being flat (see FIG. 20).
[0277] The first radius of curvature (R1) of the lens (4361) may be 5.45 cm to 6.7 cm, and the second radius of curvature (R2) of the lens (4361) may be 25 cm to infinity.
[0278] In this example, the lens (4361) may be made of a transparent material such as plastic or glass.
[0279] Additionally, the length of the multi-focal and depth of focus can be adjusted by the spherical aberration (objective curvature) of the lens (4361).
[0280] The lens (4361) of the present example may have multiple focal points (f1, ..., fn) positioned at different positions along the same optical axis from the skin surface (0.0 mm) of the subject in contact with the push button (221) to a predetermined distance (L30) into the skin, as illustrated in FIG. 20.
[0281] For example, multiple focal points (f1, ..., fn) can be formed at a distance of up to 1.5 mm (L30) from the skin surface. In this way, the positions of each focal point (f1, ..., fn) formed on the skin of the subject are distributed along the optical axis, so that the pain of the subject during blood collection can be significantly reduced.
[0282] The lens portion (436) of the present example may additionally include an anti-reflection film. In this case, the anti-reflection film may be formed by applying an anti-reflection material that prevents light reflection to the second surface of the lens (4361), i.e., the surface adjacent to the laser medium portion (431). However, in an alternative example, this anti-reflection film may be omitted.
[0283] A low-power energy laser beam output from the laser medium (431) is output toward the lens (4361) located in front of it, and then passes through the lens (4361) to be irradiated toward the corresponding skin of the subject of blood collection.
[0284] The lens holder (4362) may have a ring shape having a circular flat shape with a lens insertion port (H436) in the center portion into which a lens (4361) is inserted, and may have a pair of engaging protrusions (P436) facing each other.
[0285] At this time, the lens holder (4362) may contain an elastic material, for example, plastic, and may be made of plastic, for example.
[0286] The diameter of the lens insertion port (H436) may be equal to or smaller than the diameter (φ1) of the lens (4361), and by the elasticity of the lens holder (4362), the lens (4361) can be inserted into the lens insertion port (H436) and maintained in a stable inserted state.
[0287] This lens holder (4362) and the coupling protrusion (P436) can be mounted in the lens mounting groove (D101) located on the rear side of the front case (101), as shown in Fig. 18, and the lens unit (436) can be stably positioned without shaking by the coupling protrusion (P436).
[0288] The lens protection part (404) is spaced apart from the lens part (436) in the front case body (11) of the front case (101) and can be positioned opposite the lens part (436) to face the lens part (436).
[0289] In this example, the front case body (11) may be positioned in front of the laser output module unit (403). Accordingly, the front case body (11) may be positioned in front of the laser medium unit (431) to face the laser medium unit (431).
[0290] This front case body (11) may be equipped with a protection part mounting hole (H115) on which a lens protection part (404) is mounted. At this time, the protection part mounting hole (H115) may be located on a part of the front case body (11) that faces the lens part (436) on the opposite side of the lens part (436).
[0291] Accordingly, the lens protection part (404) can be rotated in the corresponding direction (e.g., upward direction) according to the user's movement in front of the lens part (436), and by this rotational movement, the lens protection part (404) opens the protection part mounting hole (H115) located in the front case body (11) so that the lens part (436) can be exposed to the outside through the protection part mounting hole (H115).
[0292] Additionally, the lens protection unit (404) can be positioned in the initial position by rotating in the opposite direction (e.g., downward direction) to the exposure of the lens unit (436) according to the user's action.
[0293] When the lens protector (404) is positioned in the initial position, the lens protector (404) covers the protector mounting hole (H115) to prevent the lens part (436) from being exposed to the outside through the protector mounting hole (H115). As a result, the lens part (436) can be prevented from being contaminated by soot that may be generated when the laser is fired from the laser medium part (431) toward the skin of the subject to perform a blood collection operation, or from being contaminated by dust or the like that enters from the outside.
[0294] Accordingly, the lens protection part (404) can be positioned in front of the lens part (43), more specifically, the lens holder (4362) to be rotatable in the up-and-down direction, to protect the lens part (436), and can contain an elastic material such as silicone.
[0295] Due to this lens protection part (404), the lens part (436) can be exposed to the outside or covered by the lens protection part (404) depending on the rotational state of the lens protection part (404).
[0296] The lens protection unit (404) may have a front side having a laser output port (H404) in the center and a side connected to the front side, and may have a protection unit body (4041) with an open rear side.
[0297] This protective body (4041) can be inserted and positioned in the protective body mounting hole (H115) located in the front case (101).
[0298] At this time, the protection body (4041) can be positioned so as to be openable in the protection body mounting hole (H115), so that the protection body (4041) can be positioned in the protection body mounting hole (H115) or removed from the protection body mounting hole (H115) by a physical force applied from the outside.
[0299] Additionally, the lens unit (436) can be inserted into the protective body (4041) through the open rear portion and positioned in an internal space surrounded by the front and sides.
[0300] Accordingly, the lens unit (436) located within the protective body (4041) allows the focused laser to pass through the laser output port (H221) located at the front so that it can be output toward the subject of blood collection.
[0301] The lens protector (404) may also have a handle (4041a) located on the upper side of the side of the protector body (4041) and a connecting leg (4041b) having a rotating protrusion (R404) located on the lower side.
[0302] At this time, the handle part (4041a) may be a part for rotating the lens protection part (404) in a direction desired by the user (see FIG. 11).
[0303] The rotation protrusion (R404) of the connecting leg (4041b) can be rotatably inserted into the rotation hole (H116) located in the corresponding part of the front case body (11).
[0304] Accordingly, the lens protection part (404) can be rotated forward and backward at a corresponding angle around the rotation protrusion (R404).
[0305] Accordingly, the user can rotate the lens protector (404) using the handle (4041a) to expose the lens (4361) covered by the lens protector (404) mounted on the front case (101) to the outside.
[0306] That is, when a user holds the handle (4041a) and pulls the lens protector (404) downward, the lens protector (404) can rotate in the downward direction to which force is applied based on the rotation protrusion (R404) inserted into the rotation hole (H116). Accordingly, the protection body (4041) inserted into the protection mounting hole (H115) of the front case (101) can be removed and peeled off, so that the lens part (436) can be exposed to the outside.
[0307] In this way, by rotating the lens protection part (404) in a desired direction to expose the lens part (436) covered by the protection part body (4041), the user can clean foreign substances such as dust from the lens part (436). Accordingly, the performance degradation of the lens part (436) due to foreign substances is reduced, and the lifespan of the lens part (436) can be extended.
[0308] When cleaning of the lens part (436) is completed by opening the lens protection part (404), the user can hold the handle part (4041a) and apply physical force in the opposite direction to that when opening to rotate the lens protection part (404) in the corresponding direction (e.g., upward), thereby pushing the protection part body (4041) of the lens protection part (404) into the lens insertion port (H436) of the lens part (436).
[0309] In this way, since the lens part (436) can be easily managed by the lens protection part (404) that rotates in the up and down direction, the user's convenience can be improved.
[0310] The motion control unit (405) can control the motion for generating a laser for blood collection.
[0311] Accordingly, the motion control unit (405) is connected to the laser blood collection module (40) to control the overall operation of the laser blood collection module (40), and is also connected to the blood sugar measurement module (50) and the information output unit (60) to control the operation of the blood sugar measurement module (50) and the information output unit (60).
[0312] In addition, the motion control unit (405) is also connected to the switch group (20) and the battery module (30), and can control the overall operation of the laser blood collection and blood sugar measurement device (1) using signals received from these (20, 30).
[0313] A schematic connection relationship between the motion control unit (405) of this example and the components electrically connected thereto is illustrated in FIG. 21.
[0314] This motion control unit (405) may be a processor.
[0315] The operation of this motion control unit (405) is described in detail below.
[0316] The storage unit (406) may be a memory, which is a storage medium that stores data required for the operation of the laser blood collection and blood sugar measurement device (1) of this example or data generated during the operation.
[0317] Such storage unit (406) can store, for example, the intensity level of the laser selected by the user's action.
[0318] The communication unit (407) is a part for communication with external devices and can control wireless or wired communication.
[0319] In this example, the communication unit (407) can control short-range communication such as Bluetooth, but is not limited thereto.
[0320] Next, the blood glucose measurement module (50) of the laser blood collection and blood glucose measurement device (1) of this example will be described.
[0321] The blood sugar measurement module (50) can perform an operation of measuring blood sugar using collected blood.
[0322] This blood glucose measurement module (50) may be electrically and physically connected to a plurality of electrode patterns (e.g., a reference electrode pattern and an operating electrode pattern) printed on a portion of the rear case (102) that is in contact with the test strip insertion port (H123), and may be equipped with a plurality of signal lines that apply a signal (e.g., a voltage) to the corresponding electrode patterns or receive a signal (e.g., a current) applied from the corresponding electrode patterns, a reference voltage generation unit that is connected to a corresponding signal line among these signal lines and applies a reference voltage to the reference electrode pattern, an operating signal detection unit that is connected to the corresponding signal line and detects a signal applied from the operating electrode pattern, and a measurement control unit that is connected to the reference voltage generation unit, the operating signal detection unit, and the operation control unit (405).
[0323] At this time, the measurement control unit can control the overall operation of the blood sugar measurement module (50) as a processor.
[0324] Accordingly, when the operation mode of the laser blood collection and blood sugar measurement device (1) of this example is determined to be the blood sugar measurement mode, the operation control unit (405) outputs a control signal to the measurement control unit of the blood sugar measurement module (50), so that the operation of the blood sugar measurement module (50) can begin.
[0325] Accordingly, the measurement control unit starts operation according to the control signal applied from the operation control unit (405), and determines the status of the signal line connected to each electrode pattern in the test strip insertion port (H123), thereby determining whether a blood sugar test strip has been inserted into the test strip insertion port (H123), and can also determine whether the inserted blood sugar test strip is an unusable test strip that has already been used and has blood on it, or a usable test strip that does not have blood on it.
[0326] Accordingly, the measurement control unit can transmit a signal indicating whether a blood sugar test strip coated with an enzyme for blood sugar measurement has been inserted into the test strip insertion port (H123) and whether the inserted blood sugar test strip is unusable to the operation control unit (405).
[0327] In addition, when blood is injected into a corresponding location of a blood glucose test strip on which an enzyme for blood glucose measurement is applied, the measurement control unit can calculate the blood glucose index of the corresponding blood using the state of the electric signal applied through the signal line, and then transmit the calculated blood glucose index to the operation control unit (405).
[0328] The information output unit (60) can operate under the control of the operation control unit (405) and output data received from the operation control unit (405).
[0329] For example, the information output unit (60) may be equipped with an information display unit (61) that displays visual information and an audio output unit (62) that outputs auditory information.
[0330] The information display unit (61) can use a liquid crystal display (LCD) or an organic light emitting display (OLED) using an organic light emitting diode.
[0331] Accordingly, the information display unit (61) can output an image corresponding to an image signal applied from the motion control unit (405), and, for example, can output the measured blood sugar measurement result.
[0332] The voice output unit (62) can output a voice corresponding to a voice signal received from the operation control unit (405).
[0333] For example, the voice output unit (62) may be equipped with a speaker and may output an operating sound when the laser blood collection and blood sugar measurement device (1) is in operation.
[0334] Below, the operation of the laser blood collection and blood sugar measurement device (1) of this example is described.
[0335] First, the blood collection operation on the corresponding skin of the subject of blood collection, which generates a laser for blood collection and irradiates it to the corresponding skin of the subject of blood collection, is described.
[0336] When the power required for operation is supplied through the battery (31), the operation of the laser blood collection and blood glucose measurement device (1) can begin.
[0337] First, in order to perform a blood collection operation using the laser blood collection and blood glucose measurement device (1) of this example, the user can first remove the laser protection case (103).
[0338] Then, the user (e.g., the subject or the blood drawer) can press the power switch button (211) exposed on the rear case (102) for a set time (e.g., 2 seconds) or longer to operate the power switch (212) or insert a blood glucose test strip into the test strip insertion port (H123) to supply power to the laser blood collection and blood glucose measurement device (1).
[0339] Accordingly, when the power switch (212) is operated by the operation of the power switch button (211), and for example, the power switch (212) is turned on for a set period of time, or when a blood sugar test strip is determined to be inserted by a signal applied from the blood sugar measurement module (50), the operation control unit (405) supplied with power from the battery module (30) can detect the inserted state of the blood sugar test strip and output a separate driving signal to the battery module (30).
[0340] Accordingly, the battery module (30) supplies the power required for the operation of the laser blood collection and blood glucose measurement device (1) to the corresponding components and the operation control unit (405), thereby enabling the operation of the laser blood collection and blood glucose measurement device (1) to begin.
[0341] Accordingly, when the power required for operation is supplied by the operation of the power switch unit (201) or the insertion operation of a blood sugar test strip, the operation control unit (405) can output the initial screen to the information display unit (61) of the information output unit (60) using the data stored in the storage unit (406).
[0342] In this example, the initial screen output to the information display unit (61) may, as an example, output the company name and product name, i.e., the product name for the laser blood collection and blood sugar measurement device (1).
[0343] In this way, when power supply to the laser blood collection and blood sugar measurement device (1) is completed, the operation control unit (405) can perform a blood collection operation using a laser.
[0344] In this example, when power is supplied by the power switch unit (201) or the blood sugar test strip insertion operation, the operation mode of the laser blood collection and blood sugar measurement device (1) can enter the blood collection mode.
[0345] Accordingly, when the operation control unit (405) determines that the power switch (212) is operated for a set time (e.g., 3 seconds) by a signal applied from the power switch unit (201) or the blood sugar measurement module (50) or that the blood sugar test strip is inserted into the test strip insertion port (H123), the operation control unit (405) determines that the operation mode of the laser blood collection and blood sugar measurement device (1) is a blood collection mode and controls the blood collection operation using the laser.
[0346] Accordingly, the motion control unit (405) can output a screen for blood collection mode to the information display unit (61) using the image data stored in the storage unit (406).
[0347] The screen for blood collection mode may display at least one of a status notification message (e.g., "Preparing") and an image (e.g., "Locked") indicating the current laser intensity level and the current operating state.
[0348] The initial intensity level of the laser displayed on the screen for the blood collection mode may be the intensity level of the laser used in the previous blood collection mode, depending on the data stored in the storage unit (406).
[0349] Accordingly, the operation control unit (405) outputs a control signal corresponding to the determined initial intensity level of the laser to the capacitor module unit (402), so that the charging operation of the capacitor unit (402b) can be performed according to the control of the capacitor charging unit (402a).
[0350] In this way, while the charging operation of the capacitor section (402b) is taking place, the user can re-adjust the intensity level of the laser using the first and second moving switch sections (205, 206).
[0351] Accordingly, the motion control unit (405) reads the signals applied from the first and second movement switch units (205, 206), and if it is determined that the first or second movement switch unit (205, 206) has been operated by the user, it determines which movement switch unit (205, 206) has been operated, increases or decreases the intensity level of the laser based on the current level, and stores it in the storage unit (406), and can also adjust the display status of the screen. In this way, the user can adjust the intensity level of the laser at any time according to the condition of his or her skin.
[0352] Among the first to eight levels of laser intensity selectable by the user, levels 1 to 2 may be for minors or users with sensitive skin, levels 3 to 6 may be for average adult male or female users, and levels 7 to 8 may be for users with thick skin or calluses.
[0353] When the charging operation of the capacitor unit (402b) is performed by the operation of the capacitor module unit (402) under the control of the operation control unit (405), the operation control unit (405) can determine the charging state of the capacitor unit (402b) using the charging state signal applied from the capacitor unit (402b).
[0354] Accordingly, when it is determined that the charging status of the capacitor unit (402b) is fully charged to a voltage corresponding to the intensity level of the laser, the operation control unit (405) can change the status notification message on the screen for the blood collection mode to 'ready'. Accordingly, the user can recognize that the laser blood collection and blood glucose measurement device (1) for the blood collection operation is ready by using the 'ready' message displayed on the information display unit (61).
[0355] However, if the charging of the capacitor unit (402b) is not completed in a predetermined state, the operation control unit (405) can change the status notification message on the screen for blood collection mode to 'in preparation' and output it.
[0356] Therefore, when the status of the laser blood collection and blood glucose measurement device (1) is ready, the user can operate the corresponding switch for blood collection [e.g., safety switch section (203)] to perform the operation for blood collection from the subject.
[0357] In this example, when the charging status of the capacitor section (402b) is completed with a voltage corresponding to the intensity level of the laser, the user can change the intensity level of the laser again as needed.
[0358] For example, when the status of the capacitor unit (402b) is in a charging or charging complete state, when the safety switch unit (203) is not operated, and the first or second movement switch (205, 206) is operated, the operation control unit (405) can change the current intensity level of the laser according to the operating state of the first or second movement switch (205, 206) and store it in the storage unit (406).
[0359] Due to this, the motion control unit (405) can adjust the signal applied to the capacitor charging unit (402a) to increase or decrease the size of the charging voltage of the capacitor unit (402b) according to the changed laser intensity level.
[0360] In this way, the user can change the intensity level of the laser at any time by using the movement switch (205, 206) until the safety switch (203) for the laser irradiation operation is activated.
[0361] In this way, when the intensity level of the laser is changed again depending on the operating status of the first or second moving switch (205, 206) after the charging operation of the capacitor unit (402b) is completed, the operation control unit (405) enables the information display unit (61) to indicate that charging is in progress. Accordingly, the operation control unit (405) can change the message of 'ready complete' to 'in preparation'.
[0362] Of course, if the charging operation of the capacitor unit (402b) is determined to be completed in response to the changed laser intensity level of the capacitor unit (402b), the operation control unit (405) can change the message output to the information display unit (61) back to 'ready complete'. Accordingly, the laser irradiation operation for blood collection can be performed by the user using the safety switch unit (203).
[0363] In this way, when the capacitor unit (402b) is fully charged to match the intensity level of the selected laser, the operation control unit (405) can read the signal applied from the safety switch unit (203) to determine whether the safety switch (232) of the safety switch unit (203) is in an operating state (e.g., on state).
[0364] When the safety switch (232) is judged to be in an operating state by the user's action, the operation control unit (405) can output the operating sound of the safety switch (232) to the voice output unit (62), and display the locked state of the status notification image (e.g., lock) displayed on the information display unit (61) as an unlocked state (e.g., lock is open), thereby outputting the blood collection preparation state to the information output unit (60).
[0365] When the blood collection preparation state is reached, the user can perform a blood collection operation using a laser by operating a switch for laser firing operation (e.g., a contact detection switch unit (202)). To do this, the user pushes the push button (221) on the corresponding skin area (e.g., a fingertip) of the subject from whom blood is to be collected, so that the push button (221) is pressed more than the set amount.
[0366] According to the movement of the position of the push button (221) according to the operation of the push button (221), the laser irradiation button (222) can also rotate in a predetermined direction (e.g., backward), and the laser irradiation switch (223) can be released from contact with the laser irradiation button (222) by the rotational operation of the laser irradiation button (222). As a result, the laser irradiation switch (223) can output a signal corresponding to the operating state from the initial state to the operation control unit (405).
[0367] Accordingly, when an operating state signal is applied from the laser irradiation switch (223) by the operation of the contact detection switch (202), the operation control unit (405) outputs a control signal to the capacitor module unit (402) so that the charging voltage of the capacitor unit (402b) can be applied to the lamp unit (432) to perform a discharge operation of the capacitor unit (402b).
[0368] Due to this, the lamp unit (432) can emit light with an intensity corresponding to the magnitude of the voltage applied from the capacitor unit (402b), and the laser medium unit (431) in which the excitation operation occurs due to the emission operation of the lamp unit (432) can output laser with an intensity corresponding to the magnitude of the applied voltage.
[0369] Accordingly, the laser output from the laser medium unit (431) can pass through the lens unit (436) and be irradiated onto the corresponding skin of the subject of blood collection, and the laser irradiation may cause a perforation in the corresponding skin of the subject of blood collection, causing bleeding from the corresponding skin.
[0370] In this way, the operation control unit (405) of the present example can determine whether the discharge operation of the capacitor unit (402b) is completed by using the charge status signal applied from the capacitor unit (402b) when the safety switch (232) is in an operating state and the laser irradiation switch (223) is in an operating state.
[0371] Accordingly, when it is determined that the discharge operation of the capacitor unit (402b) is completed, the operation control unit (405) can output a laser output completion sound to the voice output unit (62), and also output a laser irradiation completion message (SHOT) and an image (e.g., a lightning bolt) to the blood collection mode screen of the information display unit (61), thereby outputting a state in which the laser irradiation is completed to the information output unit (60). In an alternative example, the operation of one of the information display unit (61) and the voice output unit (62) may be omitted.
[0372] While the laser output operation is being performed under the control of the operation control unit (405), if at least one of the safety switch (232) and the laser irradiation switch (223) returns from the operating state to the non-operating state, i.e., the initial state, the operation control unit (405) can stop the laser output operation currently in progress.
[0373] Accordingly, the laser blood collection and blood glucose measurement device (1) of this example performs a laser irradiation operation for blood collection only when both switches, i.e., the safety switch (232) and the laser irradiation switch (223), remain in an operating state, so that the safety of the user can be improved.
[0374] Due to this, the user can keep the safety switch and laser irradiation switch (223) in an operating state until the laser output completion sound is output through the voice output unit (62).
[0375] As already described, the image data and audio signals for output to the information display unit (61) and audio output unit (62) may already be stored in the storage unit (406), and therefore, the operation control unit (405) may read the image data and audio signals corresponding to each state from the storage unit (406) and output them to the information display unit (61) and audio output unit (62) of the information output unit (60).
[0376] In this way, when the laser is irradiated and the blood collection operation of the corresponding skin is completed due to the operation of the lamp unit (432) caused by the discharge of the capacitor unit (402b), the operation mode of the laser blood collection and blood sugar measurement device (1) of the present example can be switched from the blood collection mode to the blood sugar measurement mode.
[0377] Accordingly, the operation control unit (405) can change the current operation mode of the laser blood collection and blood sugar measurement device (1) to the blood sugar measurement mode by outputting the laser irradiation completion status to the information output unit (60) due to the discharge completion status of the capacitor unit (402b), and can store the current operation mode of the storage unit (406) to the blood sugar measurement mode.
[0378] In this way, when the current operation mode becomes the blood sugar measurement mode, the operation control unit (405) outputs a driving signal to the blood sugar measurement module (50) so that a blood sugar measurement operation using the injected blood can be performed.
[0379] If necessary, the user can change the operation mode of the laser blood collection and blood sugar measurement device (1) to the blood sugar measurement mode using the menu selection switch unit (204). In this case, the operation control unit (405) can use the signal applied from the menu selection switch unit (204) to determine whether the operation mode of the laser blood collection and blood sugar measurement device (1) is the blood sugar measurement mode. Accordingly, the laser blood collection and blood sugar measurement device (1) can enter the blood sugar measurement mode directly without going through the laser blood collection mode, thereby improving user convenience.
[0380] In this way, when the operation mode of the laser blood collection and blood sugar measurement device (1) is set to the blood sugar measurement mode, the operation control unit (405) can control the operation for blood sugar measurement.
[0381] Below, the operation of the operation control unit (405) that controls the blood sugar measurement operation when the operation mode of the laser blood collection and blood sugar measurement device (1) is the blood sugar mode is described.
[0382] If the operation mode of the laser blood collection and blood sugar measurement device (1) stored in the storage unit (406) is the blood sugar measurement mode, the operation control unit (405) can output a screen for the blood sugar measurement mode to the information display unit (61).
[0383] Accordingly, the user can recognize that the laser blood collection and blood sugar measurement device (1) of the present example is currently in blood sugar measurement mode for measuring blood sugar using the information displayed on the information display unit (61).
[0384] For example, under the control of the motion control unit (405), the information display unit (61) can output a guidance message saying ‘Please insert a test strip’ through the screen for blood sugar measurement mode.
[0385] Therefore, the user can insert a blood sugar test strip for blood sugar testing into the test strip insertion port (H123).
[0386] Under the control of the motion control unit (405), in an alternative example, the user changes the operation mode of the laser blood collection and blood sugar measurement device (1) to the blood sugar measurement mode using the menu selection switch unit (204) so that the blood sugar measurement operation can be performed.
[0387] To this end, the user can switch the status of the laser blood collection and blood sugar measurement device (1) to the operation start state by removing the laser protection case (103) similar to the laser blood collection operation and using the power switch (201) or blood sugar test strip.
[0388] Then, the user selects the blood sugar measurement mode using the menu selection switch unit (204) so that the operation mode of the laser blood collection and blood sugar measurement device (1) can be the blood sugar measurement mode. Accordingly, the operation control unit (405) can read the signal applied from the menu selection switch unit (204) to determine the operating status of the menu selection switch unit (204), and can switch the operation mode of the laser blood collection and blood sugar measurement device (1) to the blood sugar measurement mode and store it in the storage unit (406). Then, the operation control unit (405) can output a screen for the blood sugar measurement mode to the information display unit (61).
[0389] In this way, after outputting the guidance message ‘Please insert a test strip’, the motion control unit (405) can determine whether a blood sugar test strip has been inserted into the test strip insertion port (H123) using a signal received from the blood sugar measurement module (50).
[0390] If it is determined that a blood sugar test strip is inserted into the test strip insertion port (H123), the operation control unit (405) can output a guidance message saying ‘Please inject blood’ on the screen for blood sugar measurement mode.
[0391] In an alternative example, when power is supplied using a blood sugar test strip instead of the power switch unit (201), the operation control unit (405) can determine that a blood sugar test strip is inserted into the test strip insertion port (H123) by a signal applied from the blood sugar measurement module (50).
[0392] Accordingly, if it is determined that a blood sugar test strip is inserted into the test strip insertion port (H123), the operation control unit (405) can output a guidance message saying 'Please inject blood' instead of a guidance message saying 'Please insert a test strip' on the screen for blood sugar measurement mode.
[0393] Accordingly, the user can use the laser to apply the collected blood to a designated location on the blood glucose test strip.
[0394] In this way, when blood is applied to the corresponding location of the blood sugar test strip, the blood sugar test strip can generate an electric current of the corresponding size according to the content of sugar contained in the blood by the action of an enzyme at the corresponding location, and the generated current can be input to the blood sugar measurement module (50) through the electrode in contact with it.
[0395] Accordingly, the blood sugar measurement module (90) can use the size of the input current to determine the blood sugar level of the blood applied to the blood sugar test strip, and then output the determination result, i.e., the measured blood sugar index, to the operation control unit (405).
[0396] In this way, while blood is injected into a blood glucose test strip and a blood glucose measurement operation is performed by the blood glucose measurement module (50), the operation control unit (405) may output, for example, a guidance message saying 'Please inject blood' and then output an image indicating the blood glucose measurement status on the screen for the blood glucose measurement mode.
[0397] Next, when blood sugar measurement by the blood sugar measurement module (50) is completed, the blood sugar measurement module (50) can output the measured blood sugar index to the operation control unit (405).
[0398] Accordingly, the motion control unit (405) can generate blood sugar measurement data using the blood sugar index transmitted from the blood sugar measurement module (50), and then output the generated blood sugar measurement data to an information output unit (60), for example, an information display unit (61).
[0399] At this time, blood sugar measurement data may include one of the measured blood sugar index, measurement date and time, and fasting time (e.g., 8 hours fasting, 1 hour postprandial, 2 hours postprandial, and other (postprandial)). At this time, other may be a state excluding 8 hours fasting, 1 hour postprandial, and 2 hours postprandial.
[0400] The measurement date and time can be obtained using a clock (not shown) located in the laser blood collection and blood sugar measurement device (1), and the fasting time can be the fasting time of the subject when the blood sugar measurement is performed.
[0401] In this example, the fasting time may be set to 8 hours by default. This fasting time can be changed based on the user's (e.g., the person drawing the blood).
[0402] In this way, when blood sugar measurement data is generated, the motion control unit (405) can read the signals applied from the first and second movement switch units (205, 206) of the generated blood sugar measurement data to determine whether the blood sugar measurement data is stored and the exact fasting time.
[0403] The menus selectable by at least one of the first and second moving switch units (205, 206) may be ‘Do not save’, ‘Fast (8 hours)’, ‘1 hour after meal’, ‘2 hours after meal’, or ‘Other (after meal)’.
[0404] Accordingly, after outputting blood sugar measurement data to the information display unit (61), the operation control unit (405) can read the signals applied from the first and second movement switch units (205, 206), the signals applied from the blood sugar measurement module (50), and the signals applied from the menu selection switch unit (204).
[0405] After the blood sugar measurement data is output to the information display unit (61), if it is determined that the blood sugar test strip is removed from the test strip insertion port (H123) without the operation of the first and second moving switch units (205, 206) or the menu selection switch unit (204) is determined to be operated for less than the set time, the operation control unit (405) may store the generated blood sugar measurement data in the storage unit (406) and then terminate the blood sugar measurement operation. In this case, the state of the fasting time may be 'fasting (8 hours)' indicating a state in which the fasting time is 8 hours.
[0406] However, if it is determined that at least one of the first and second movement switch units (205, 206) is operated before the blood sugar measurement data is output to the information display unit (61) and the blood sugar test strip is removed from the test strip insertion port (H123) or the menu selection switch unit (204) is operated for less than a set time (e.g., 2 seconds), the operation control unit (405) can determine the operating status of the first and second movement switch units (205, 206).
[0407] Accordingly, if it is determined that 'do not save' is selected by the operation of at least one of the first and second moving switch units (205, 206), the operation control unit (405) can end the blood sugar measurement operation without saving the currently generated blood sugar measurement data.
[0408] On the other hand, after the blood sugar measurement data is output to the information display unit (61), if it is determined that one of the menus related to the fasting time ['fasting (8 hours),' '1 hour after meal,' '2 hours after meal,' or 'other (after meal)'] (e.g., 1 hour after meal) is selected by the operation of at least one of the first and second moving switch units (205, 206) before the blood sugar test strip is removed from the test strip insertion port (H123) or before the menu selection switch unit (204) is operated for less than a set time (e.g., 3 seconds), the operation control unit (405) can change the information related to the fasting time state in the currently generated blood sugar measurement data to the determined fasting state (e.g., 1 hour after meal) to modify new blood sugar measurement data to generate final blood sugar measurement data, and then output the new blood sugar measurement data to the information display unit (61).
[0409] Then, if it is determined that the blood sugar test strip is removed from the test strip insertion port (H123) or the menu selection switch (204) has been operated for less than a set time (e.g., 3 seconds), the operation control unit (405) can store the modified blood sugar measurement data in the storage unit (406) and terminate the blood sugar measurement operation.
[0410] While the laser blood collection operation or blood sugar measurement operation is being performed under the control of this operation control unit (405), the user can change the operation mode of the laser blood collection and blood sugar measurement device (1) to the setting mode using the menu selection switch (204).
[0411] For example, the operation control unit (405) may read a signal applied from the menu selection switch unit (204) while the laser blood collection operation or blood sugar measurement operation is being performed, and if it is determined that the menu selection switch (242) has been operated for a set time (e.g., 3 seconds) or longer, the operation mode of the laser blood collection and blood sugar measurement device (1) may be determined to be the setting mode. At this time, the operation control unit (405) may change the operation mode stored in the storage unit (406) to the setting mode.
[0412] Therefore, when the operation mode of the laser blood collection and blood sugar measurement device (1) is determined to be the setting mode, the operation control unit (405) can control the operation selected by the user by determining the operation status of at least one of the menu selection switch unit (204) and the movement switch unit (205, 206).
[0413] In this example, the settings mode can perform at least one of the following settings: whether to delete data, setting the clock, setting the unit of blood sugar level, whether to output sound, and setting the language.
[0414] Whether to delete data can be selected to delete or cancel the deletion of the selected blood glucose measurement results. Accordingly, if cancel deletion is selected by the movement switch unit (205, 206), the operation control unit (405) can output a message asking whether deletion is really desired through the information display unit (61). Then, if the signal applied from the menu selection switch unit (204) is read and it is determined that the menu selection switch unit (204) is in an operating state (e.g., in an operating state for less than a set time), the operation control unit (204) can delete all blood glucose measurement data stored in the storage unit (406).
[0415] Clock settings allow you to change the current time (at least one of year, month, day, hour, minute, and second).
[0416] Setting the blood sugar level unit allows you to set the blood sugar level unit to your preference. User-selectable units for blood sugar levels include mg / dL or mmol / L.
[0417] The purpose of determining whether or not to output sound is to determine whether or not the set sound will be output to the voice output unit (62) whenever each switch unit (201-207) is operated. Accordingly, when the state of whether or not to output sound is selected as the 'sound output' state, the sound set in the storage unit (406) can be output to the voice output unit (62) depending on the operation of the switch unit (201-207).
[0418] Additionally, the language setting is for selecting the type of language used in the laser output and blood glucose measurement device (1) of this example. In this example, the selectable language may be Korean or English. Accordingly, the operation control unit (405) can determine the type of language selected and select the type of language output to the information display unit (61).
[0419] For these clock settings, unit settings for blood sugar index, sound output, and language settings, the motion control unit (405) reads the signal applied from the movement switch unit (205, 206) to determine what has been selected by the user and can change the corresponding data to the selected one.
[0420] In addition, after power is supplied, if the operation mode of the laser blood collection and blood sugar measurement device (1) selected by the user is determined to be the memory mode by the operation of the menu selection switch unit (204), the operation control unit (405) can read the blood sugar measurement results stored in the storage unit (406) and output them to the information display unit (61) of the information output unit (60).
[0421] Accordingly, the user can check the blood sugar measurement data generated at the desired measurement time by using the first and second movement switch units (205, 206) and the menu selection switch unit (204). At this time, the information display unit (61) of the information output unit (60) can display the blood sugar measurement data in the order of the measurement time.
[0422] The power-off operation of the laser blood collection and blood sugar measurement device (1) can be performed using the power switch unit (201) or the blood sugar test strip removal operation.
[0423] To this end, when the power switch (212) of the power switch unit (201) is operated for a set time (e.g., 2 seconds) or longer while the power is supplied to the operation control unit (405), the operation control unit (405) can determine whether a blood sugar test strip is currently inserted into the test strip insertion port (H123) using a signal applied from the blood sugar measurement module (50).
[0424] Accordingly, if a blood sugar test strip is currently inserted into the test strip insertion port (H123), the operation control unit (405) can output a message, such as ‘Please remove the test strip’, to the information display unit (61), requesting the removal of the blood sugar test strip from the test strip insertion port (H123).
[0425] Therefore, if the blood sugar test strip is removed by the user, the operation control unit (405) can control the operation of the battery module (30) to cut off the supplied power.
[0426] However, if a blood sugar test strip is currently inserted into the test strip insertion port (H123), the operation control unit (405) can control the operation of the battery module (30) according to the operation of the power switch unit (201) to cut off the supplied power.
