[Technical Field]
[0001] The present invention relates to a body-attachable unit. More specifically, the present invention relates to a body-attachable unit for measuring blood glucose, which is manufactured in an assembled state within an applicator, minimizing additional work and allowing the body-attachable unit to be attached to the body simply by operating the applicator. In particular, the body-attachable unit is equipped with a wireless communication chip to enable communication with an external terminal, eliminating the additional work of connecting a separate transmitter, making it simple and convenient to use and easier to maintain. The body-attachable unit can be activated by a user's operation after being attached to the body, allowing the activation time to be adjusted to an appropriate time according to the user's needs.

[0002] Diabetes is a chronic disease that occurs frequently among modern people, affecting over 2 million people in Korea, or 5% of the total population.
[0003] Diabetes occurs when there is an absolute or relative deficiency of insulin produced by the pancreas due to various causes such as obesity, stress, poor eating habits, and congenital genetics, which prevents the blood from quickly balancing out the sugar content, resulting in an absolute excess of sugar in the blood.
[0004] Blood normally contains a certain concentration of glucose, from which tissue cells obtain their energy.
[0005] However, if glucose levels increase more than necessary, they cannot be properly stored in the liver, muscles, or fat cells and instead accumulate in the blood. As a result, diabetics maintain blood sugar levels much higher than normal people, and the excess blood sugar passes through the tissues and is excreted in the urine, resulting in a shortage of sugar, which is absolutely necessary for each tissue in the body, causing abnormalities in each tissue.
[0006] Diabetes is characterized by the fact that in the early stages there are almost no noticeable symptoms, but as the disease progresses, specific symptoms of diabetes such as excessive drinking, eating, urination, weight loss, general fatigue, itchy skin, and persistent wounds on the hands and feet that do not heal appear.As the disease progresses further, complications such as vision problems, high blood pressure, kidney disease, stroke, periodontal disease, muscle spasms and neuralgia, and gangrene appear.
[0007] In order to diagnose and manage diabetes so that it does not progress to complications, systematic blood glucose monitoring and treatment must be carried out simultaneously.
[0008] For people with diabetes and those who have not progressed to diabetes but have higher than normal levels of sugar in their blood, many medical device manufacturers offer a variety of blood glucose monitors that allow people to measure their blood sugar at home.
[0009] There are two types of blood glucose monitors: one in which the user takes a blood sample from the tip of a finger and measures blood glucose one time, and one in which the device is attached to the user's abdomen or arm and measures blood glucose continuously.
[0010] Diabetic patients generally experience a state of alternating between hyperglycemia and hypoglycemia, and emergency situations often occur when the patient is in a hypoglycemic state, leading to loss of consciousness, or even death if the hypoglycemic state continues for a long period without a supply of sugar. Therefore, prompt detection of hypoglycemic states is extremely important for diabetic patients, but blood glucose meters that measure blood glucose intermittently have limitations in accurately detecting this state.
[0011] Recently, to overcome these limitations, a continuous glucose monitoring system (CGMS) has been developed that is inserted into the human body to measure blood glucose levels every few minutes, making it easier to manage diabetes patients and respond to emergency situations.
[0012] In addition, blood glucose meters measure blood glucose levels by pricking the fingertips of diabetics, which are sensitive to pain, with a needle to collect blood, which can cause pain and discomfort during the blood collection process. To minimize this pain and discomfort, research and development is underway on continuous blood glucose monitoring systems that measure blood glucose continuously after inserting a needle-shaped sensor into areas where pain is relatively less, such as the abdomen or arm. Furthermore, research and development on non-invasive glucose monitoring systems that measure blood glucose without drawing blood has also been actively underway.
[0013] For the past 40 years, research has been ongoing into various methods for non-invasive blood glucose monitoring, including optical, electrical, and breath-based methods for measuring blood glucose without drawing blood. Cygnus (Redwoo City, CA, USA) developed and marketed the Glucowatch G2 Biographer, a wristwatch that uses reverse iontophoresis. However, sales were halted in 2007 due to issues such as skin irritation, calibration issues, the device shutting down during sweating, and the inability to accurately detect hypoglycemia compared to hyperglycemia. While many blood-free blood glucose monitoring technologies have been reported to date, they are not yet practical due to their lack of accuracy.
[0014] The continuous blood glucose monitoring device comprises a sensor module that is attached to the skin to extract body fluid and measure blood glucose, a transmitter that sends the blood glucose value measured by the sensor module to a terminal, and the terminal that outputs the received blood glucose value, etc. The sensor module is equipped with a needle-shaped sensor probe that is inserted into subcutaneous fat to extract interstitial fluid, and a separate applicator is used to attach the sensor module to the body.
[0015] These continuous blood glucose monitors are manufactured in a wide variety of forms by different manufacturers, and there are also various ways of using them. However, most continuous blood glucose monitors are manufactured and distributed in a way that a single-use sensor module is attached to the body via an applicator, and the user must perform many steps to operate the applicator to attach the single-use sensor module to the body, and after attaching the sensor module to the body, they must also perform various follow-up procedures, such as directly removing the needle.
[0016] For example, the packaging of a single-use sensor module must be removed and accurately inserted into the applicator. With the sensor module inserted in the applicator, the applicator must be operated to insert the sensor module into the skin. After insertion, the needle of the sensor module must be directly removed from the skin using a separate tool. In addition, a separate transmitter must be connected to the sensor module to send the blood glucose measurement results to the user terminal.
[0017] Therefore, the process of measuring blood glucose using a continuous blood glucose meter is very cumbersome and inconvenient, and the inability to start the sensor module and transmitter by the user can lead to problems such as reduced accuracy of blood glucose measurement results and a shortened device lifespan. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]
[0018] The present invention has been invented to solve the problems of the prior art, and its object is to provide a body-attachable unit for continuous blood glucose measurement that minimizes the additional work required by the user to attach the body-attachable unit to the body by manufacturing the body-attachable unit in an assembled state within an applicator, allowing the body-attachable unit to be attached to the body simply by operating the applicator, and in particular, to provide a body-attachable unit for continuous blood glucose measurement that is simple and convenient to use and easier to maintain, as it is equipped with a wireless communication chip in the body-attachable unit to enable communication with an external terminal, eliminating the additional work of connecting a separate transmitter.
[0019] Another object of the present invention is to provide a body-attachable unit for continuous blood glucose measurement that can be activated by a user's operation after attaching the body-attachable unit to the body, allowing the activation start time to be adjusted to an appropriate time according to the user's needs, and that can be activated in a stable state, allowing for more accurate blood glucose measurement. [Means for solving the problem]
[0020] The present invention provides a body-attachable unit for continuous blood glucose measurement that is inserted and attached to the body through an applicator for continuous blood glucose measurement, comprising: a housing whose bottom is adapted to be attached to the skin; a PCB board arranged inside the housing; a sensor member arranged inside the housing with one end protruding outward from the bottom of the housing so that when the housing is attached to the skin, one end is inserted into the body and the other end can be brought into contact with an electrical contact of the PCB board; and a pressure actuation module that is operated by a user to apply pressure to the other end of the sensor member to bring it into contact with the electrical contact of the PCB board, wherein the pressure actuation module is fixed in a state different from before the actuation when it is completed by a user's operation.
[0021] At this time, the pressure actuation module may be formed so that the state before and after actuation can be distinguished by the naked eye.
[0022] The pressure actuation module may include a movable pressure body movably coupled to the housing and configured to move in response to a user's pressure to pressurize at least a portion of the other end of the sensor member to contact the electrical contact of the PCB board, and a soft button cover coupled to the housing so as to be exposed to the outside and surround an upper surface of the movable pressure body to allow a user to perform a pressure operation.
[0023] In addition, a pressure protrusion protruding upward is formed on the upper surface of the movable pressure body, and the button cover is attached to be in close contact with the pressure protrusion in a state before the pressure operating module is activated, and is elastically deformed by the pressure protrusion to be protruded upward. When the pressure operating module is activated and the movable pressure body moves downward, the close contact with the pressure protrusion is released, and the button cover can be restored to a flat state.
[0024] Also, the movable pressure body may be configured to be fixed in position in a state where it is moved in a pressure direction by a user's pressure.
[0025] In addition, the movable pressure body is formed with a protruding guide portion that protrudes in a moving direction of the movable pressure body, and a locking hook is formed on an outer peripheral surface of the protruding guide portion. The housing is formed with an interlocking protrusion that can be interlocked with the locking hook of the protruding guide portion when the movable pressure body moves in the pressing direction, and the movable pressure body can be fixed in position by interlocking the locking hook with the interlocking protrusion.
[0026] Also, the pressure actuation module may be configured to be actuated by bringing the other end of the sensor member into contact with an electrical contact of the PCB board. [Effects of the Invention]
[0027] According to the present invention, the body-attachable unit is manufactured in an assembled state within the applicator, minimizing the additional work required by the user to attach the body-attachable unit to the body, and the body-attachable unit can be attached to the body simply by operating the applicator. In particular, the body-attachable unit is equipped with a wireless communication chip to enable communication with an external terminal, eliminating the additional work of connecting a separate transmitter, making it simple and convenient to use and easier to maintain.
[0028] In addition, by allowing the user to start operation after attaching the body-attachable unit to the body, the start time of operation can be adjusted to an appropriate time according to the user's needs, and operation can be started in a stable state, which has the effect of enabling more accurate blood glucose measurement.

First, when adding reference numerals to components in each drawing, it should be noted that identical components are assigned the same reference numerals as much as possible even if they are displayed in different drawings. Furthermore, in describing the present invention, if it is determined that detailed description of related known configurations or functions may obscure the gist of the present invention, such detailed description will be omitted.

[0032] The continuous blood glucose monitoring device according to one embodiment of the present invention is manufactured as a single unit product by assembling the body-attachable unit 20 inside the applicator 10, and has a very simple structure that minimizes additional work for the user when using the continuous blood glucose monitoring device.
[0033] The body-attachable unit 20 is configured to be attached to the body so that it can extract body fluids and periodically measure blood glucose, and is configured to transmit blood glucose measurement results to an external device such as an external terminal (not shown). The body-attachable unit 20 includes a sensor member 520, one end of which is inserted into the body, and a wireless communication chip 540 (see FIG. 27) disposed therein so as to enable wireless communication with the external terminal, and therefore can be used without the need for an additional transmitter.
[0034] The applicator 10 is configured to have the body attachment unit 20 attached and fixed thereto, and is operated to discharge the body attachment unit 20 to the outside by the user's operation.
[0035] At this time, the body attachment unit 20 is assembled in a state inserted inside the applicator 10, and is configured to move in the direction of external discharge and attach to the body when the applicator 10 is operated by the user.
[0036] That is, the sensor applicator assembly 1 according to one embodiment of the present invention is assembled and supplied to a user in a manufacturing process such that the body-attachable unit 20 is attached to the skin simply by operating the applicator 10 with the body-attachable unit 20 inserted inside the applicator 10, and the user can attach the body-attachable unit 20 to the skin simply by operating the applicator 10 without any additional steps to attach the body-attachable unit 20 to the skin. In particular, the body-attachable unit 20 is provided with a separate wireless communication chip 540, eliminating the need to connect a separate transmitter and making it more convenient to use.
[0037] In conventional continuous blood glucose measuring devices, the separately packaged body-attached unit must be unwrapped and then precisely inserted into the applicator. After insertion, the applicator must be operated to attach the body-attached unit to the skin. However, the process of precisely inserting the body-attached unit into the applicator is cumbersome and difficult, and for children and the elderly, this process can contaminate the body-attached unit, reducing the accuracy of blood glucose measurement.
[0038] In one embodiment of the present invention, the body-attached unit 20 is manufactured and distributed in a state where it is inserted into the applicator 10 during the manufacturing stage, eliminating the need for the user to unwrap the body-attached unit 20 and insert it into the applicator 10. The body-attached unit 20 can be attached to the skin simply by operating the applicator 10, dramatically improving usability and, in particular, preventing contamination of the body-attached unit 20 and improving the accuracy of blood glucose measurement.
[0039] Since the body attachment unit 20 is manufactured in a state where it is inserted into the applicator 10, it is desirable that the body attachment unit 20 and the applicator 10 are used for single use and not for reuse. Due to this non-reusable structure, the applicator 10 according to one embodiment of the present invention is configured so that the body attachment unit 20 cannot be reinserted after it has been operated once so that the inserted body attachment unit 20 is discharged to the outside.
[0040] That is, the applicator 10 is formed with one side open, and the body-attachable unit 20 is configured to be discharged to the outside through the open side of the applicator 10. However, once the internal body-attachable unit 20 is discharged to the outside through the first operation of the applicator 10, it can be configured so that it is not possible to insert another body-attachable unit 20 into the applicator 10 and use it thereafter.
[0041] Meanwhile, a separate protective cap 200 may be detachably attached to the applicator 10 so that the body-attachable unit 20 is prevented from being exposed to the outside when inserted inside the applicator 10, and the user may be configured to operate the applicator 10 to attach the body-attachable unit 20 to the body only after removing the protective cap 200.
[0042] At this time, an adhesive tape 560 is attached to the body contact surface of the body attachment unit 20 so that the body attachment unit 20 can be attached to the body, and a release paper 561 is attached to the body contact surface of the adhesive tape 560 to protect the adhesive tape 560, and the release paper 561 of the adhesive tape 560 can be formed so as to be separated and removed from the adhesive tape 560 in the process of separating the protective cap 200 from the applicator 10.
[0043] For example, the release paper 561 may be configured so that one side is adhered to the protective cap 200, and therefore, when the user separates the protective cap 200 from the applicator 10, the release paper 561 can be separated and removed together with the protective cap 200 from the adhesive tape 560. As a result, when the user separates the protective cap 200, the release paper 561 of the adhesive tape 560 is separated and removed, and in this state, the applicator 10 can be operated to attach the body attachment unit 20 to the body.
[0044] In addition, the applicator 10 can be configured to fasten the body-attachable unit 20 when the body-attachable unit 20 is inserted inside, and to release the fastened state when the body-attachable unit 20 is moved and discharged to the outside. Therefore, when the body-attachable unit 20 is inserted and assembled inside the applicator 10, the body-attachable unit 20 remains fixed, and when the applicator 10 is operated to discharge the body-attachable unit 20 to the outside and attach it to the skin, the fastened state between the applicator 10 and the body-attachable unit 20 is released. Therefore, when the applicator 10 is separated in this state, it is separated from the body-attachable unit 20, and only the body-attachable unit 20 remains attached to the skin.
[0045] Meanwhile, the body-attachable unit 20 according to one embodiment of the present invention may be configured so that the sensor member 520 and the wireless communication chip 540 are activated through a separate switch operated by the user. That is, after inserting and attaching the body-attachable unit 20 to the body through the applicator 10, the user can activate the body-attachable unit 20 through a switch provided on the body-attachable unit 20. From this activation point, the sensor member 520 and the wireless communication chip 540 are activated to measure the blood glucose level and transmit the measurement results to an external terminal. The switch operated by the user may be configured in various ways, and the switch means and the body-attachable unit 20 will be described in detail below with reference to Figures 26 to 37.
[0046] In addition, the body-attachable unit 20 has a sensor member 520 disposed inside a housing 510 that is separated into an upper housing 512 and a lower housing 511, and one end of the sensor member 520 protrudes from the housing 510 so as to be inserted and attached to the body. The sensor member 520 is composed of a sensor probe part 521 that is inserted into the body and a sensor body part 522 that is disposed inside the housing 510, and the sensor probe part 521 and the sensor body part 522 are bent and form one end and the other end of the sensor member 520, respectively.
[0047] At this time, to facilitate the process of inserting the sensor member 520 into the body, a separate needle portion 550 may be detachably coupled to the housing 510. The needle portion 550 is configured to surround one end of the sensor member 520 and be inserted into the body together with the sensor member 520 so that one end of the sensor member 520 can be stably inserted into the body.
[0048] 2, the needle 550 is detachably attached in a direction that vertically penetrates the housing 510 of the body-attachable unit 20, and is formed in a form that surrounds the outside of the sensor member 520, with a needle head 551 formed at its upper end. When the body-attachable unit 20 is moved in the outward discharge direction by the applicator 10, the needle 550 is inserted into the body before the sensor member 520, thereby helping the sensor member 520 to be stably inserted into the skin. The needle 550 is coupled to the needle puller body 400 of the applicator 10 through the needle head 551, and is configured to be pulled out and removed from the body by the needle puller body 400 of the applicator 10 after the body-attachable unit 20 is inserted and attached to the body by actuation of the applicator 10.
[0049] Next, the detailed structure of the applicator 10 according to one embodiment of the present invention will be described in more detail.
[0050] The applicator 10 according to one embodiment of the present invention comprises a main case 100 having a pressure button 110 attached to one side thereof so that the pressure button 110 can be pressed by the user; a plunger body 300 which is coupled and fixed to a first position inside the main case 100 and which is released from the first position by operation of the pressure button 110 and moves linearly to a second position in the direction of external discharge; and a plunger elastic spring (S1) which applies an elastic force to the plunger body 300 so that the plunger body 300 moves linearly from the first position to the second position. The body-attachable unit 20 is coupled to one end of the plunger body 300 and moves integrally with the plunger body 300 from the first position to the second position.
[0051] As described above, a separate protective cap 200 is detachably coupled to the lower end of the main case 100 to protect the internal body attachment unit 20 .
[0052] 6 to 8, the protective cap 200 may include an outer cover part 201 formed to surround the outer circumferential surface of the applicator 10 in contact with the outer circumferential surface and be coupled to one end of the applicator 10, an extension part 202 extending from one end of the outer cover part 201 toward the center of the inside of the applicator 10, and an inner support part 203 extending upward from the extension part 202 to support the body contact surface of the body attachment unit 20 inserted inside the applicator 10. In this case, a sensor protection part 204 may be formed at the center of the inner support part 203 to locally protrude downward so as to surround the sensor probe 521 and the needle part 550 protruding downward from the body contact surface of the body attachment unit 20.
[0053] Therefore, the protective cap 200 not only blocks the external exposure of the body-attachable unit 20 inserted inside the applicator 10 but also performs a support function for the body-attachable unit 20, thereby improving the overall structural safety of the applicator.
[0054] Meanwhile, as shown in Figures 7 and 8, adhesive tape 560 and release paper 561 are attached to the body contact surface of the body attachment unit 20, and the release paper 561 of the adhesive tape 560 is formed so as to be separated and removed from the adhesive tape 560 together with the protective cap 200 in the process of separating the protective cap 200 from the applicator 10.
[0055] 7, a separate adhesive member 562 is attached to one side of the release paper 561, and the separate adhesive member 562 is positioned between the top surface of the inner support portion 203 of the protective cap 200 and the release paper 561, with the bottom surface of the adhesive member 562 being attached to the top surface of the inner support portion 203 of the protective cap 200. The adhesive strength of the adhesive member 562 is greater than the adhesive strength between the release paper 561 and the adhesive tape 560. Therefore, when the protective cap 200 is separated from the applicator 10, the release paper 561 attached to the inner support portion 203 of the protective cap 200 through the adhesive member 562 is separated and removed from the adhesive tape 560.
[0056] At this time, two incision lines (not shown) having a distance equal to the width of the adhesive member 562 may be formed parallel to each other in a certain section of the release paper 561, and therefore, as shown in Fig. 8, in the process of separating the protective cap 200, the release paper 561 together with the adhesive member 562 is first separated and released from the adhesive tape 560 along the incision lines, and thereafter, as the separation process of the protective cap 200 continues, i.e., as the protective cap 200 continues to move downward in the direction shown in Fig. 8, the release paper 561 in the portion other than the incision lines is pulled and separated and removed from the adhesive tape 560. Through this release paper separation and removal process, the separation and removal of the release paper 561 can be performed more smoothly and stably.
[0057] A pressure button 110 is attached to the main case 100 so that the user can press the button 110, and a shooting plate 150 is movably coupled inside the main case 100 so that the shooting plate 150 moves when the pressure button 110 is pressed.
[0058] The plunger body 300 is engaged with the shooting plate 150 at the first position and fixedly coupled thereto, and is disengaged as the shooting plate 150 moves, and is moved to the second position by the elastic force of the plunger elastic spring (S1).
[0059] The main case 100 may be formed separately from an outer case 101 on one side of which a pressure button 110 is attached, and an inner case 102 which is coupled to the inside of the outer case 101 and is formed to guide the linear movement path of the plunger body 300, and the shooting plate 150 is seated and supported on the inner case 102 so that it can move.
[0060] 9, the outer case 101 has a button guide groove 1011 formed therein so that the pressure button 110 can be pressed. The pressure button 110 is configured to be pressurized so that it can rotate around a hinge shaft 112 formed on the upper end, and has a pressure rod 111 formed on the lower end so that it can pressurize the shooting plate 150. A separate fastening hook 113 is formed on one side of the pressure button 110 to prevent it from separating.
[0061] Such a pressure button 110 is mounted so as to be mode-switchable between a safety mode in which pressure movement by pressure operation is blocked and a pressure standby mode in which pressure movement by pressure operation is possible.
[0062] The pressure button 110 may be configured to slide a certain distance along the outer surface of the main case 100 in the safety mode state to be converted into a pressure standby mode state. A locking protrusion 1012 may be formed on the main case 100 at a location where the pressure button 110 is attached, and in the safety mode state, the pressure button 110 engages with the locking protrusion 1012 to prevent pressure movement, and by sliding from the safety mode state to the pressure standby mode state, the pressure button 110 disengages from the locking protrusion 1012, allowing pressure movement.
[0063] That is, as shown in FIG. 10, when the pressure button 110 is in the safety mode, it engages with the locking protrusion 1012 of the outer case 101, making it impossible to apply pressure, and as shown in FIG. 11, when the pressure button 110 moves upward in the pressure standby mode, it is released from the engagement with the locking protrusion 1012 of the outer case 101, making it possible to apply pressure.
[0064] The pressure button 110 may be configured to be fixed in position so that it will not return to the safety mode state if it is slid from the safety mode state to the pressure standby mode state.
[0065] To this end, a fixing protrusion 114 is formed on one side of the pressure button 110, and an elastically deformable cut-out deformation portion 1013 is formed in the bottom surface of the button guide groove 1011 of the outer case 101 by cutting out a portion thereof, and the cut-out deformation portion 1013 has an accommodating groove 1014 into which the fixing protrusion 114 can be inserted and accommodated when the pressure button 110 is in the safety mode, and is formed so that when the pressure button 110 has completed moving to the pressure standby mode, its end surface engages with the fixing protrusion 114 to restrict the return movement of the pressure button 110.
[0066] With this structure, the pressure button 110 can be operated by the user only when it is slid to the pressure standby mode, preventing accidental pressure operation by the user and ensuring safe use. In particular, if the safety mode is switched to the pressure standby mode, it is not possible to return to the safety mode again, thereby encouraging careful operation by the user and maintaining a stable operating state.
[0067] When the pressure button 110 is switched to the pressure standby mode and is pressed as shown in FIG. 12, the pressure rod 111 of the pressure button 110 pressurizes and moves the shooting plate 150.
[0068] The shooting plate 150 is seated and supported on the inner case 102 and is coupled to be slidable by the pressure operation of the pressure button 110, and the plunger body 300 engages with the shooting plate 150 at the first position, disengages from the shooting plate 150 as the shooting plate 150 moves, and moves to the second position by the elastic force of the plunger elastic spring (S1).
[0069] As shown in Figures 12 and 13, the plunger body 300 is formed with a mating hook 310 to be mated with the shooting plate 150, and one side of the shooting plate 150 is formed with a locking protrusion 153 that can be mated with the mating hook 310 of the plunger body 300, and the locking protrusion 153 is formed so that the mating state with the mating hook 310 is released as the shooting plate 150 slides.
[0070] A guide rail 162 is formed to protrude from the inner case 102 to guide the sliding movement path of the shooting plate 150, and a guide slot 151 is formed in the shooting plate 150 to guide the insertion of the guide rail 162. In addition, an elastic member 163 is attached to the inner case 102 to elastically support the shooting plate 150 in the direction opposite to the sliding direction caused by operation of the pressure button 110. Therefore, the shooting plate 150 is elastically supported toward the pressure button 110 by the elastic force of the elastic member 163, and so as long as the pressure button 110 is not operated to apply pressure, the engagement state between the plunger body 300 and the engagement hook 310 is stably maintained.
[0071] With this structure, when the user presses the pressure button 110, the shooting plate 150 slides, thereby releasing the engagement between the plunger body 300 and the shooting plate 150, and the plunger body 300 moves from the first position to the second position for external discharge as shown in Figures 15 and 16 due to the elastic force of the plunger elastic spring (S1).
[0072] A stopper protrusion 320 may be formed on the plunger body 300 to limit the range of movement to the second position, and the stopper protrusion 320 may be engaged with one side of the inner case 102 when the plunger body 300 moves to the second position, thereby limiting the movement of the plunger body 300. That is, the plunger body 300 is prevented from moving to the second position by the stopper protrusion 320 and is not ejected beyond that range from the main case 100. At this time, the inner case 102 may be formed with a stopper fixing portion 1021 that is engaged with the stopper protrusion 320 when the plunger body 300 moves to the second position, thereby restricting the movement of the stopper protrusion 320.
[0073] In addition, a sensor receiving portion 301 is formed at one end of the plunger body 300 so that the body-attachable unit 20 can be inserted and accommodated therein, and the body-attachable unit 20 is inserted and accommodated in the sensor receiving portion 301 and moves linearly from the first position to the second position together with the plunger body 300. As the plunger body 300 and the body-attachable unit 20 move linearly to the second position, the sensor probe 521 and the needle portion 550 of the body-attachable unit 20 are inserted into the body.
[0074] At this time, a sensor fixing hook 330 is attached to the edge of the sensor receiving part 301, which can be engaged with and fixed to the body attachment unit 20 inserted into the sensor receiving part 301. On both ends of the body attachment unit 20, there are formed fitting grooves 5112 so that the fitting grooves 5112 can be engaged with the sensor fixing hook 330 when the body attachment unit 20 is inserted into the sensor receiving part 301.
[0075] The sensor-securing hook 330 is coupled to be elastically rotatable about the rotation axis 331, and when the plunger body 300 is positioned at the first position, the sensor-securing hook 330 is elastically supported to be pressed inward so as to engage with the engaging groove 5112 of the body-attached unit 20 as shown in Fig. 15. When the plunger body 300 is positioned at the second position, the sensor-securing hook 330 can be configured to disengage from the engaging groove 5112 of the body-attached unit 20 during the process of separating the applicator 10 from the body-attached unit 20 as shown in Fig. 16. The process of disengaging the sensor-securing hook 330 from the body-attached unit 20 can be achieved by the rotation axis 331 being twisted and elastically rotated.
[0076] Although not shown, a hook guide portion (not shown) having a cross-sectional shape that presses the sensor fixing hook 330 inward to engage with the body-attachable unit 20 and releases the pressure on the sensor fixing hook 330 when the plunger body 300 moves to the second position may be formed on the inner wall surface of the inner case 102. That is, the hook guide portion may have a protruding surface and a concave surface on the inner wall surface of the inner case 102, and the protruding surface is formed to press the sensor fixing hook 330 and the concave surface is formed to release the pressure on the sensor fixing hook 330 when the sensor fixing hook 330 moves to the second position together with the plunger body 300.
[0077] On the other hand, in the present invention, the body attachment unit 20 is manufactured in a state where it is inserted into the applicator 10, and as mentioned above, it is configured to prevent another body attachment unit 20 from being inserted into the applicator 10 and reused.
[0078] For this purpose, the main case 100 is provided with a return prevention means for preventing the plunger body 300 from returning to the first position after the plunger body 300 has moved to the second position.
[0079] As shown in Figures 17 to 19, the return prevention means may include an engagement body 340 formed on one side of the plunger body 300, and a return prevention hook 161 formed on the inner case 102 to engage with the engagement body 340 of the plunger body 300 and prevent the plunger body 300 from returning when the plunger body 300 has completed its downward movement from the first position to the second position.
[0080] The return prevention hook 161 is configured to be engaged by an elastic restoring force in the process of engaging with the engaging body 340. More specifically, the return prevention hook 161 may include a rotating body 1611 coupled to one side of the inner case 102 so as to be elastically rotatable about a rotating shaft 1613, and a hook body 1612 protruding inward and downward from the inner surface of the rotating body 1611. In this case, the rotating shaft 1613 is formed to elastically support the rotating body 1611 in a direction in which the hook body 1612 protrudes inward due to the elastic force acting on it due to the material properties of the elastic material.
[0081] This return prevention hook 161 prevents the plunger body 300 from moving back toward the first position after completing its movement from the first position to the second position, thereby preventing the user from arbitrarily inserting and using another body attachment unit 20.
[0082] Looking closely at the operation of the return prevention hook 161, when the plunger body 300 is moved to the second position by operating the pressure button 110 while it is in the first position as shown in Fig. 17, as the plunger body 300 moves to the second position as shown in Fig. 18, the hook body 1612 is pressed by the interlocking body 340 of the plunger body 300, causing the return prevention hook 161 to elastically rotate in the clockwise direction (outward direction) around the rotation axis 1613. Thereafter, when the plunger body 300 completes its movement to the second position as shown in Fig. 19, the interlocking body 340 releases the pressure on the hook body 1612, causing the return prevention hook 161 to elastically rotate in the counterclockwise direction (inward direction) around the rotation axis 1613. As the return prevention hook 161 elastically rotates in this manner, the lower end of the return prevention hook 161 engages with the upper end of the engagement body 340 of the plunger body 300, and thus the plunger body 300 is prevented from returning to the first position due to the engagement state between the return prevention hook 161 and the engagement body 340.
[0083] Meanwhile, the applicator 10 is configured to withdraw and remove the needle portion 550 of the body attachment unit 20 from the body as the body attachment unit 20 completes its external discharge movement from the first position to the second position, and for this purpose, the applicator 10 may be provided with a needle withdrawal means (N) that moves the needle portion 550 upward and withdraws and removes it from the body as the plunger body 300 completes its movement from the first position to the second position.
[0084] The needle withdrawing means (N) may include a needle withdrawing body 400 that is coupled to the needle head 551 of the needle portion 550, engages with the plunger body 300, and moves linearly from a first position to a second position along the inner case 102 together with the plunger body 300, and a needle withdrawing elastic spring (S2) that applies an elastic force to the needle withdrawing body 400 in the direction in which the needle withdrawing body 400 moves upward toward the first position.
[0085] The needle puller body 400 is engaged with the plunger body 300, and for this purpose, a separate elastic hook 410 that can be elastically deformed is formed on the needle puller body 400, and the elastic hook 410 is elastically deflected in a direction that engages with the hook engaging portion 350 of the plunger body 300. Therefore, when the plunger body 300 moves linearly from the first position to the second position by operating the pressure button 110, the needle puller body 400 also moves linearly with the plunger body 300 to the second position.
[0086] At this time, the inner case 102 is formed with a needle pull-out pressure part 130 that presses the elastic hook 410 inward so that the elastic hook 410 disengages from the hook engagement part 350 of the plunger body 300 as the needle pull-out body 400 moves to the second position.
[0087] With this structure, when the pressure button 110 is pressed, the needle puller body 400 moves linearly from the first position to the second position together with the plunger body 300 as shown in FIG. 19. At the same time, the elastic hook 410 of the needle puller body 400 is pressed by the needle puller pressure part 130 of the inner case 102, and the engagement with the hook engagement part 350 is released. As a result, the needle puller body 400 moves upward and returns to the first position due to the elastic force of the needle puller elastic spring (S2) as shown in FIG. 20.
[0088] At this time, the needle puller body 400 is connected to the needle head 551 of the needle portion 550 through the needle head connecting portion 420 at one end, so that as the needle puller body 400 returns upward, the needle portion 550 moves along with it and is pulled out and removed from the body. The needle head connecting portion 420 is formed at the lower end of the needle puller body 400 in a form that engages with and connects to the connecting groove 552 formed in the needle head 551.
[0089] Meanwhile, the sensor probe 521 and the needle 550 of the body-attachable unit 20 are inserted into the body as the plunger body 300 moves to the second position due to the elastic force of the plunger elastic spring (S1). However, during the insertion of the needle 550 into the body, insertion resistance may occur, and the needle 550 may be slightly retracted in the opposite direction to the body insertion direction due to the reaction force. In this case, the sensor probe 521 may not be inserted into the body to the correct depth, so it is desirable to prevent the needle 550 from retracting. For this reason, the needle drawer body 400 may be coupled with a needle support block that supports the upper end of the needle 550 downward so that the needle 550 does not move upward relative to the needle drawer body 400.
[0090] Next, the state of use of the sensor applicator assembly described above will be examined in detail with reference to Figs. 21 to 25.
[0091] 21 to 25 are diagrams showing the operation steps of a continuous blood glucose measuring device according to an embodiment of the present invention.
[0092] First, as shown in Fig. 21, the protective cap 200 of the applicator 10 is separated. In the process of separating the protective cap 200, the release paper 561 of the adhesive tape 560 of the body-attachable unit 20 is separated together with the protective cap 200 and removed from the adhesive tape 560. Thereafter, the sensor applicator assembly is positioned at the body position where the body-attachable unit 20 is to be attached, and in this state, the pressure button 110 is switched from the safety mode to the pressure standby mode, and then the pressure button 110 is pressed.
[0093] When the pressure button 110 is pressed, the shooting plate 150 moves and disengages from the plunger body 300. As a result, the plunger body 300 moves downward in the direction of external discharge due to the plunger elastic spring (S1) as shown in Figures 22 and 23. During this process, the needle 550 and sensor probe 521 of the body-attachable unit 20 are inserted into the body (E). Of course, at this time, the body-attachable unit 20 is attached to the surface of the body (E) by the adhesive tape 560 on its bottom surface. When the plunger body 300 moves in the direction of external discharge, the plunger body 300 engages with the return prevention hook 161 of the inner case 102 as shown in Figure 23, preventing it from moving upward again. Therefore, a used applicator 10 cannot be reused.
[0094] Meanwhile, when the plunger body 300 according to one embodiment of the present invention is moved to the second position in the outward discharging direction, the lower end surfaces of the plunger body 300 and the body-attachable unit 20 coupled to the plunger body 300 are formed to be flush with the lower end surface of the main case 100, as shown in Fig. 22. However, as shown in the enlarged view of Fig. 22, the lower end surface of the plunger body 300 may be formed to protrude downward by a distance X from the lower end surface of the main case 100, and therefore the lower end surface of the body-attachable unit 20 coupled to the plunger body 300 also protrudes downward by a distance X from the lower end surface of the main case 100.
[0095] In this way, the plunger body 300 is configured to protrude further from the opening of the main case 100 when it elastically moves, allowing the body-attachable unit 20 connected to the plunger body 300 to adhere more firmly to the body surface. In particular, even if the user secretly lifts or moves the main case 100 from the body surface due to fear or other reasons while operating the applicator, the plunger body 300 operates to protrude further from the opening of the main case 100, allowing the body-attachable unit 20 to be in stable pressure contact with the body surface.
[0096] 23, the sensor fixing hook 330 of the sensor receiving part 301 may be disengaged from the body-attachable unit 20. Also, the elastic hook 410 of the needle puller body 400 is pressed inward by the needle puller pressure part 130 of the inner case 102, disengaging from the plunger body 300.
[0097] Therefore, when the plunger body 300 moves downward, the needle puller body 400 simultaneously moves upward due to the needle puller elastic spring S2 as shown in Figure 24. At this time, the needle 550 moves upward together with the needle puller body 400, so that the needle 550 is pulled out and removed from the body E.
[0098] In this state, as described above, the engagement between the sensor fixing hook 330 and the body-attachable unit 20 can be released, so the applicator 10 can be separated and removed upward as shown in Figure 25. Once the applicator 10 is separated and removed in this manner, only the body-attachable unit 20 remains attached to the body (E).
[0099] Thereafter, the pressure actuation module 570 of the body-attachable unit 20 can be operated to start the operation of the sensor member 520 and wireless communication chip 540 of the body-attachable unit 20, and the blood glucose measurement result by the body-attachable unit 20 is transmitted to a separate external terminal. In the present invention, since the sensor member 520 and the wireless communication chip 540 are both provided in the body-attachable unit 20, additional work such as connecting and coupling a separate transmitter is not required.
[0100] Next, we will look in more detail at the body-attachable unit 20 according to one embodiment of the present invention.
[0101] Figure 26 is a perspective view showing the outline of a body attachment unit attached to the body according to one embodiment of the present invention, Figure 27 is an exploded perspective view showing the configuration of a body attachment unit according to one embodiment of the present invention, Figure 28 is a cross-sectional view taken along line "CC" in Figure 26, Figure 29 is a cross-sectional view taken along line "DD" in Figure 26, and Figure 30 is a drawing showing the operating state of a pressurized operating module according to one embodiment of the present invention.
[0102] The body-attachable unit 20 according to one embodiment of the present invention comprises a housing 510 having an adhesive tape 560 attached to the bottom surface so that the bottom surface can be attached to the skin, a sensor member 520 arranged inside the housing 510 so that one end protrudes from the bottom surface of the housing 510 and is inserted into the body when the housing 510 is attached to the skin, and a PCB board 530 arranged inside the housing 510.
[0103] The sensor member 520 has one end formed to be inserted into the body and the other end formed to be in contact with the PCB board 530. The other end is formed with a sensor body part 522 to be in contact with an electrical contact of the PCB board 530, and one end is formed with a sensor probe part 521 that is bent and extended from one side of the sensor body part 522 to protrude out of the housing 510 and be inserted into the body. The sensor body part 522 is formed to have a relatively wide area, and the sensor probe part 521 is formed to be relatively narrow and long.
[0104] The housing 510 may be separated into an upper housing 512 and a lower housing 511 to form an internal storage space, and a sensor support 5121 is formed inside the housing 510 to support the sensor body 522 at a predetermined distance from the electrical contact 531 of the PCB board 530, and a sensor guide (not shown) is formed to support and guide a portion of the sensor probe 521. Also, a board support 5113 may be formed inside the housing 510 to fix and support the PCB board 530 in a predetermined position.
[0105] Electrical contacts 531 are formed on the PCB board 530 to electrically connect with the sensor member 520, and a wireless communication chip 540 is mounted on the PCB board 530 to transmit the blood glucose measurement results measured through the sensor member 520 to an external terminal. In one embodiment of the present invention, the wireless communication chip 540 is provided inside the body-attachable unit 20, thereby enabling easy communication with an external terminal without the need for a separate transmitter connection.
[0106] Furthermore, a battery 535 is mounted inside the housing 510 to supply power to the PCB board 530, but the battery 535 is not mounted on one side of the PCB board 530 but is arranged in an area independent of the PCB board 530. That is, the PCB board 530 and the battery 535 are arranged independently without overlapping each other in their areas reflected on the bottom surface of the housing 510. As such, the PCB board 530 and the battery 535 are arranged in independent areas, which allows the thickness of the body-attachable unit 20 to be reduced and the size to be further reduced. At this time, a separate contact terminal 532 may be formed on the PCB board 530 extending toward the battery 535 so as to be electrically connected to the battery 535.
[0107] The body-attachable unit 20 according to an embodiment of the present invention is configured such that the other end of the sensor member 520, i.e., the sensor body part 522, is configured to contact the electrical contact 531 of the PCB board 530 by user operation, and such electrical contact initiates operation of the body-attachable unit 20. That is, the body-attachable unit 20 may be configured such that power is supplied and the sensor member 520 and the wireless communication chip 540 are activated by the electrical connection between the sensor member 520 and the PCB board 530 by user operation.
[0108] In order to bring the other end of the sensor member 520 into contact with the electrical contact 531 of the PCB board 530 by a user's operation, the housing 510 may be provided with a separate pressure actuation module 570 that is actuated by a user's operation.
[0109] The pressure actuation module 570 may include a movable pressure body 571 that is movably connected to the housing 510 and moves in a pressure direction in response to a pressure applied by a user, and may be configured such that as the movable pressure body 571 moves, at least a portion of the other end of the sensor member 520 is compressed and deformed by the movable pressure body 571 to come into contact with the electrical contact 531 of the PCB board 530.
[0110] In addition, the pressure actuation module 570 may further include a button cover 572 made of a soft material that is connected to the housing 510 so as to be exposed to the outside in a form that surrounds the external space of the movable pressure body 571 and allows the user to perform a pressure operation, and the connecting portion of the button cover 572 and the housing 510 may be configured to be sealed.
[0111] In this case, the sealing of the joining portion of the button cover 572 and the housing 510 may be performed using a double-sided tape 580. For example, the double-sided tape 580 may be attached along the edge of the other end of the sensor member 520, i.e., one surface of the sensor body part 522, and the inner surface of the button cover 572 may be attached along the edge to the striking surface of the double-sided tape 580, so that the edge of the button cover 572 may be sealed by the double-sided tape 580. In this case, the double-sided tape 580 may also be attached along the edge of the striking surface of the sensor body part 522, and thus the edge of the sensor body part 522 may be adhered and fixed to the sensor support part 5121 using the double-sided tape 580.
[0112] 30, with the edge of the sensor body part 522 adhered and fixed to the sensor support part 5121 with the double-sided tape 580, the central region of the sensor body part 522 is deformed by pressure from the movable pressure body 571 and can come into contact with the electrical contact 531 of the PCB board 530. The movable pressure body 571 moves in the pressure direction, but since the button cover 572 is made of a soft material and its edge is adhered to the housing 510 with the double-sided tape 580, only the central region is deformed in the pressure direction, and the edge is adhered and fixed, maintaining a sealed state.
[0113] Meanwhile, after the sensor body part 522 contacts the electrical contact 531 of the PCB board 530 by user operation, it is desirable that the contact state be stably maintained for stable blood glucose measurement. To this end, the movable pressure body 571 may be formed to be fixed in position while moving in the pressure direction due to the pressure applied by the user.
[0114] 31, the movable pressure body 571 may be formed with a protruding guide portion 5711 that protrudes in the moving direction of the movable pressure body 571, and a locking hook 5712 may be formed on the outer circumferential surface of the protruding guide portion 5711. Also, the housing 510 may be formed with an interlocking protrusion 5124 that may be interlocked with the locking hook 5712 of the protruding guide portion 5711 when the movable pressure body 571 moves in the pressing direction. The movable pressure body 571 may be configured to be fixed in position by interlocking the locking hook 5712 with the interlocking protrusion 5124, as shown in FIG.
[0115] At this time, the interlocking protrusions 5124 may be formed on the sensor support portion 5121 of the housing 510, and at least two guide fixing portions 5123 may be formed on the sensor support portion 5121 of the housing 510, spaced apart in the circumferential direction, so as to surround the protruding guide portion 5711 of the movable pressure body 571, as shown in Fig. 31, and the interlocking protrusions 5124 may be formed on each guide fixing portion 5123. Also, each guide fixing portion 5123 may be disposed in a form in which it is elastically supported by an elastic support portion 5125 that is elastically deformable.
[0116] Therefore, as the movable pressure body 571 moves in the pressure direction, the guide fixing part 5123 elastically deforms to facilitate the movement of the movable pressure body 571, and when the movement of the movable pressure body 571 is completed, the guide fixing part 5123 elastically returns to its original shape, causing the locking hook 5712 to engage with the engaging protrusion 5124, and the guide fixing part 5123 is elastically supported by the elastic support part 5125, so that the engaged state of the locking hook 5712 and the engaging protrusion 5124 is stably maintained.
[0117] Meanwhile, the sensor member 520 is composed of the sensor body part 522 and the sensor probe part 521 as described above, and the sensor body part 522 has a pressure deformation part 523 which is deformed by the pressure movement of the movable pressure body 571 and contacts the electrical contact 531 of the PCB board 530.
[0118] As shown in FIG. 32, the pressure deformation portion 523 includes a first cutout region 5231 formed along a first cutout line 5232 formed in the central region of the sensor body portion 522, and the first cutout region 5231 can be formed to be pressure deformed by the movable pressure body 571.
[0119] In addition, the pressure deformation part 523 further includes a second cutout area 5233 formed in the central region of the sensor body part 522 along a second cutout line 5234 formed in the outer region of the first cutout line 5232, and the first cutout area 5231 and the second cutout area 5233 can be formed to be pressure deformed by the movable pressure body 571.
[0120] In this case, the first incision line 5232 is formed in a closed loop with a portion of the incision line open, and the second incision line 5234 is formed in a closed loop shape that surrounds the open portion of the first incision line 5232 from the outside and has an open portion at a position opposite the open portion of the first incision line 5232.
[0121] When the movable pressure body 571 is pressed using this structure, as shown in (a) and (b) of Figures 33A and 33B, the first cutout area 5231 of the pressure deformation part 523 is elastically deformed downward, and the second cutout areas 5233 formed in the outer area of the first cutout area 5231 are elastically deformed downward in succession. As a result, the first cutout area 5231, which is in direct contact with the electrical contact 531 of the PCB board 530, comes into contact with the electrical contact 531 of the PCB board 530 in a relatively horizontal state, thereby more stably maintaining the contact state of the sensor body part 522 with the electrical contact 531.
[0122] Meanwhile, a plurality of electrical contacts 531 that electrically contact the sensor body part 522 are formed on the PCB substrate 530 in a form that protrudes toward the sensor body part 522, and at least one of the plurality of electrical contacts 531 may be formed to have a higher protruding height than the rest.
[0123] For example, as shown in FIG. 34, when two electrical contacts 531 are formed on the PCB substrate 530, the protruding height of one electrical contact 531 is formed higher than the protruding height of the other electrical contact 531, and thus the distances d1 and d2 from the sensor body part 522 are formed to be different from each other.
[0124] This arrangement structure can prevent the sensor body part 522 from coming into contact with the electrical contact 531 even without a pressure operation by the user due to manufacturing and assembly tolerances.
[0125] More specifically, according to one embodiment of the present invention, sensor body part 522 of sensor member 520 and electrical contact 531 of PCB board 530 are positioned to be spaced apart from each other within housing 510 and are configured to come into contact with each other when a user applies pressure. However, because housing 510 is formed in a very thin shape, it is very difficult to stably maintain the spaced apart state between sensor body part 522 and electrical contact 531 within it. In particular, due to tolerances that occur during manufacturing and assembly, sensor body part 522 and electrical contact 531 may be manufactured and distributed in a state of contact with each other before a user applies pressure.
[0126] As described above, if the protruding height of at least one of the plurality of electrical contacts 531 is made higher than the remaining electrical contacts 531, even if the sensor body part 522 and the electrical contacts 531 come into contact with each other due to manufacturing and assembly tolerances, only the highest protruding electrical contact 531 comes into contact with the sensor body part 522, and the remaining electrical contacts 531 are maintained spaced apart from the sensor body part 522. This is because the highest protruding electrical contact 531 functions to support the sensor body part 522 upward. In this case, the plurality of electrical contacts 531 may be formed in an elastically deformable form so as to elastically protrude from the PCB substrate 530, and this elastic force allows them to smoothly perform their functions of supporting and contacting the sensor body part 522.
[0127] Even if the sensor body part 522 and the electrical contacts 531 are in contact with each other, if only one of the electrical contacts 531 is in contact, the operation of the body-attachable unit 20 will not be initiated. In other words, the operation of the sensor member 520 and the wireless communication chip 540 will not be initiated, and the supply of power through the battery 535 will not be initiated.
[0128] This function of preventing activation can be achieved by a simple method such as configuring the pattern circuit of the PCB substrate 530 so that activation occurs only when all of the electrical contacts 531 are in contact with the sensor body portion 522.
[0129] In this way, when the plurality of electrical contacts 531 are formed to have different protruding heights, the moving distance of the movable pressure body 571 of the pressure actuation module 570 must be greater than the distance between the electrical contact 531 with the lowest protruding height among the plurality of electrical contacts 531 and the sensor body part 522.
[0130] The above describes the configuration of the pressure actuation module 570, which operates by applying pressure to the contact structure between the sensor body part 522 and the electrical contact 531 through user operation. However, it can be configured in various ways other than the pressure actuation method, and some exemplary configurations will be described in detail below.
[0131] 35 to 37 are diagrams conceptually illustrating various configurations of a contact connection module according to an embodiment of the present invention.
[0132] 35 to 37 show a contact connection module 590 that is operated by user operation to bring the sensor body part 522 and the electrical contacts 531 of the PCB board 530 into contact with each other. This contact connection module 590 can be configured to be positioned to cut off mutual contact between the sensor body part 522 and the electrical contacts 531 of the PCB board 530, and then moved by user operation to release the cut off mutual contact.
[0133] More specifically, the electrical contacts 531 of the PCB substrate 530 are formed to elastically protrude in a direction to contact the sensor body portion 522, and the contact connection module 590 operates to release the mutual contact between the electrical contacts 531 of the sensor body portion 522 and the PCB substrate 530, so that the electrical contacts 531 of the PCB substrate 530 can be configured to elastically move due to elastic force and contact the other end of the sensor member 520.
[0134] In this case, the contact connection module 590 may be configured to include a movable plate 591 that is disposed between the sensor body part 522 and the electrical contact 531 of the PCB board 530 inside the housing, as shown in FIG. 35, and is movably mounted by user operation.
[0135] As shown in Figure 35(a), when movable plate 591 is inserted into housing 510 in an assembled state, it is located between sensor body part 522 and electrical contact 531, cutting off mutual contact between sensor body part 522 and electrical contact 531. When movable plate 591 is pulled out of housing 510 by the user and moved in the direction of removal, as shown in Figure 35(b), electrical contact 531 moves upward due to elastic force and comes into contact with sensor body part 522.
[0136] Meanwhile, as shown in FIG. 36, the movable plate 591 is mounted so as to be movable from a first position to a second position by the user's operation, and a through hole 593 may be formed on one side of the movable plate 591 so that the electrical contact 531 is pressed against the PCB board 530 at the first position and the electrical contact 531 is released from the pressed state at the second position.
[0137] Therefore, when the movable plate 591 is positioned at a first position inside the housing 510 as shown in FIG. 36(a), the movable plate 591 blocks the mutual contact between the sensor body part 522 and the electrical contact 531. When the movable plate 591 moves to a second position inside the housing 510 as shown in FIG. 36(b), the through-hole 593 of the movable plate 591 is positioned between the electrical contact 531 and the sensor body part 522, so that the electrical contact 531 elastically moves and passes through the through-hole 593 to come into contact with the sensor body part 522.
[0138] At this time, the moving plate 591 may be formed with a stopper portion 592 to limit the moving range of the moving plate 591 from the first position to the second position.
[0139] Meanwhile, the moving plate 591 may be fixed in the second position so that it cannot return to the first position.
[0140] For example, a locking hook 594 is formed on one end of the movable plate 591, and an interlocking protrusion 595 is formed inside the housing 510, which can interlock with the locking hook 594 when the movable plate 591 is moved to the second position, and the movable plate 591 can be fixed in position at the second position by the locking hook 594 interlocking with the interlocking protrusion 595.
[0141] 37, a contact connecting member 596 made of a conductive material may be separately attached to the moving plate 591. This may be configured in such a way that the contact connecting member 596 is attached to the portion of the moving plate 591 where the through hole 593 is formed, and the electrical contact 531 and the sensor body part 522 may be electrically connected by the contact connecting member 596 when the moving plate 591 moves.
[0142] 38 and 39 are diagrams schematically illustrating the structure of a mode change lock member of a pressure button according to an embodiment of the present invention.
[0143] The pressure button 110 according to the embodiment of the present invention is mounted so as to be switchable between a safety mode in which pressure movement due to a pressure operation is blocked and a pressure standby mode in which pressure movement due to a pressure operation is possible, as described above.
[0144] At this time, the pressure button 110 is provided with a lock member 115 for blocking and unlocking the mode conversion state of the pressure button 110 .
[0145] The locking member 115 is configured to maintain the blocking state so that the pressure button 110 is prevented from being converted from the safety mode state to the pressure standby mode state, and to release the blocking state by the user's operation.
[0146] The pressure button 110 is slidably mounted in the button guide groove 1011 of the main case 100, and is switched between a safety mode and a pressure standby mode by sliding. That is, the pressure button 110 is maintained in the safety mode within the button guide groove 1011, and is slid by the user's operation to switch to the pressure standby mode.
[0147] At this time, the locking member 115 blocks the mode conversion of the pressure button 110 by restricting the sliding movement of the pressure button 110. For example, the locking member 115 may be configured such that one end is coupled to the pressure button 110 and the other end is engaged with the button guide groove 1011 to restrict the sliding movement of the pressure button 110.
[0148] More specifically, the locking member 115 may include a locking body 1151, one end of which is coupled to the pressure button 110 so as to be operable by a user, as shown in FIG. 38, and a locking hook 1152 formed to protrude from one side of the locking body 1151 and engage with the inner peripheral surface of the button guide groove 1011.
[0149] In this case, the lock body 1151 is rotatably coupled to the pressure button 110, and when a user rotates the lock body 1151, the lock hook 1152 is released from its engagement with the button guide groove 1011. The rotatable structure of the lock body 1151 may be configured using a hinge or the like, but as shown in Figures 38 and 39, it may also be configured so that a user can easily rotate it using a coupling part made of a flexible material.
[0150] In addition, the lock body 1151 may be formed to be elastically deformable, and configured so that the engagement of the lock hook 1152 with the button guide groove 1011 is released when the user rotates the lock body 1151 to elastically deform it; and the lock body 1151 may be coupled to the pressure button 110 so that it can be separated and removed, and configured so that the engagement of the lock hook 1152 with the button guide groove 1011 is released when the user separates and removes the lock body 1151.
[0151] In this way, the mode change is performed through a separate locking member 115 in the process of changing the pressure button 110 from the safety mode to the pressure standby mode, which encourages the user to pay more attention when changing the mode and prevents the applicator from being operated by mistake or tampering.
[0152] In addition, the locking member 115 may be formed so that the operating state of the pressure button 110, whether it is blocking or unlocking the mode change, can be distinguished by the naked eye by the user. As described above, if the locking body 1151 of the locking member 115 is formed to extend so as to protrude from one side of the pressure button 110 and is configured to be operated by rotating it, the user can easily distinguish the locking member 115 and can easily grasp the operating state of the locking member 115, i.e., whether it is blocking or unlocking the mode change, which can lead to even safer use.
[0153] 40 and 41 are diagrams schematically illustrating the structure and operation of a pressurizing operation module according to still another embodiment of the present invention.
[0154] The pressure actuation module 570 includes a movable pressure body 571 that moves in response to the pressure of the user to pressurize the other end of the sensor member 520, and a soft button cover 572 that surrounds the upper surface of the movable pressure body 571, as described above.
[0155] Since button cover 572 is made of a flexible material and is connected to housing 510 in a form surrounding the upper surface of movable pressure body 571, after movable pressure body 571 has completed its downward movement due to the user's pressure operation, button cover 572 is maintained in a form that can be freely deformed due to the characteristics of the flexible material without a separate support member. In this case, not only is it unsightly, but it is also difficult for the user to clearly distinguish whether pressure operating module 570 has been pressurized or not.
[0156] The pressure actuation module 570 according to another embodiment of the present invention is configured to be fixed in a state different from that before actuation by completing actuation through user operation, and in particular, is configured so that the state before and after actuation can be distinguished by the naked eye of the user.
[0157] 40, a pressing protrusion 5713 that protrudes upward is formed on the upper surface of the movable pressing body 571, and the button cover 572 is attached so as to be elastically deformed so as to protrude upward by the pressing protrusion 5713 before the operation of the pressing actuation module 570. Therefore, an elastic protrusion 5721 that is elastically deformed so as to protrude upward by the pressing protrusion 5713 of the movable pressing body 571 is formed in the center of the button cover 572.
[0158] 41, when the pressure actuating module 570 is actuated and the movable pressure body 571 moves downward, the button cover 572 is released from the tight contact state with the pressure protrusion 5713 and is restored to a flat state. That is, the elastic protrusion 5721 is restored to a flat state.
[0159] With this structure, the button cover 572 is elastically supported and fixed by its own elastic force with its upper surface flat when the movable pressure body 571 moves downward due to the operation of the pressure operating module 570. Also, before the pressure operating module 570 is operated, an elastic protrusion 5721 is protruded from the center of the button cover 572, but after the pressure operating module 570 is operated, the elastic protrusion 5721 of the button cover 572 is restored to a flat state, so that the protruding and released states of the elastic protrusion 5721 appear before and after the operation of the pressure operating module 570, making it easy to distinguish the state before and after operation with the naked eye.
[0160] FIG. 42 is a diagram schematically illustrating the structure of a pressurizing operation module according to still another embodiment of the present invention.
[0161] As shown in FIG. 42, the moving pressure body 571 and the button cover 572 of the pressure actuation module 570 can be integrally formed.
[0162] Since the movable pressure body 571 made of a rigid material and the button cover 572 made of a flexible material are formed independently, when the pressure operating module 570 is operated and the movable pressure body 571 moves downward as described above, the button cover 572 may deform freely, which causes problems such as difficulty in manufacturing and increased costs due to the need to manufacture them separately.
[0163] To solve this problem, the movable pressure body 571 and the button cover 572 can be integrally formed. In this case, the movable pressure body 571 can be made of a flexible material, like the button cover 572, to improve the workability of the pressure actuation module 570, and the movable pressure body 571 can be made thicker to have a relatively high rigidity.
[0164] In this case, the movable pressure body 571 and the button cover 572 can be manufactured integrally in one process, and the soft material has excellent workability, preventing damage to the sensor member 520 due to interference or wear.
[0165] FIG. 43 is a perspective view schematically showing a detailed configuration of a sensor member according to still another embodiment of the present invention.
[0166] As described above, the sensor member 520 may include a sensor body part 522 having a pressure deformation part 523 formed in a central region to contact the electrical contact of the PCB board, and a sensor probe part 521 formed in a bent shape extending from one side of the sensor body part 522 and inserted into the body.
[0167] At this time, the pressure-deforming portion 523 is formed in a form in which a portion thereof is cut out, but in another embodiment of the present invention, a bridge portion 524 is formed on the cut line of the pressure-deforming portion 523 in a form in which a portion thereof is not cut out.
[0168] More specifically, the pressure deformation portion 523 may be configured to include a first cutout region 5231 cut along a first cutout line 5232 as described above, and a second cutout region 5233 cut along a second cutout line 5234, and the bridge portion 524 may be formed in a partial section of multiple fulcrums of the first cutout line 5232 and the second cutout line 5234.
[0169] In this way, the bridge portion 524 is formed in a shape that is not cut in a portion of the cut line of the pressure deformation portion 523, thereby preventing problems such as deformation of the cut area due to its own weight or due to careless handling during the assembly or manufacturing process.
[0170] That is, if the pressure-deforming portion 523 is formed in the incision area, the pressure-deforming portion 523 can be easily deformed due to mistakes such as careless handling by the operator, but if the pressure-deforming portion 523 is deformed in this manner regardless of the user's operation, problems occur such as the pressure-deforming portion 523 coming into contact with an electrical contact without the user's operation. In another embodiment of the present invention, by forming a bridge portion 524 at the incision line, the bridge portion 524 supports the pressure-deforming portion 523 and prevents it from being easily deformed, thereby maintaining more accurate and stable operating performance.
[0171] FIG. 44 is a perspective view illustrating an example of a shape of a pressure-deformable portion of a sensor member according to an embodiment of the present invention.
[0172] The sensor body part 522 of the sensor member 520 has a pressure-deformable part 523 formed in a cut shape along the cut line as described above.
[0173] In this case, the pressure deformation portion 523 may include a first cutout area 5231 cut along a first cutout line 5232 and a second cutout area 5233 cut along a second cutout line 5234 formed in the outer region of the first cutout line 5232.
[0174] This shape is merely an example, and the incision lines may be modified in various ways. For example, as shown in Fig. 44(a), the first incision line 5232 and the second incision line 5234 may be formed in a curved shape.
[0175] Also, as shown in (b) of FIG. 44, the first incision line 5232 may be formed in a spiral shape. In this case, the movable pressure body 571 of the pressure actuation module 570 may be formed to pressurize the central region along the spiral-shaped first incision line 5232. When pressed by the movable pressure body 571, the first incision region 5231 is deformed sequentially from the central region to the outer region along the spiral-shaped first incision line 5232, so that it can stably contact the electrical contacts of the PCB board even without a separate second incision line and second incision region.
[0176] Figure 45 is a diagram illustrating various modified examples of a sensor member according to one embodiment of the present invention, Figure 46 is a cross-sectional view taken along the "EE" line of Figure 45 to explain the electrode stack structure of a sensor member according to one embodiment of the present invention, and Figures 47 and 48 are cross-sectional views taken along the "EE" line of Figure 45 to explain the electrode stack structure of a sensor member according to another embodiment of the present invention.
[0177] The sensor member 520 is formed long in one direction so that one end can be inserted into the body, and the other end is formed to contact the electrical contact of the PCB board.
[0178] The sensor member 520 has a sensor body part 522 at the other end thereof so as to contact an electrical contact, and a sensor probe part 521 at one end thereof extending from one side of the sensor body part 521 so as to be inserted into the body.
[0179] The shape of the sensor member 520 can be varied in a variety of ways, but as shown in Figure 45(a), the sensor body part 522 can be formed in a flat plate shape with a relatively wide area, or as shown in (b) and (c), it can be formed in a thin and long shape with a bent or unbent middle region. These are merely examples, and various other shapes are possible.
[0180] The sensor probe 521 of the sensor member 520 has a plurality of electrode layers formed thereon so as to be inserted into the body and measure information on various substances in the body fluid.
[0181] More specifically, as shown in Figure 46, it comprises a substrate 5201 having one end formed long in one direction so as to be inserted into the body, a first electrode layer 5202 formed on the upper surface of at least one end of substrate 5201, a first insulating layer 5203 formed so as to surround the upper surface of first electrode layer 5202, a second electrode layer 5204 formed on the upper surface of first insulating layer 5203, and a second insulating layer 5205 formed so as to surround the upper surface of second electrode layer 5204.
[0182] Looking at the electrode layer stacking process in detail, as shown in Figure 46(a), a first electrode layer 5202, a first insulating layer 5203, a second electrode layer 5204, and a second insulating layer 5205 are sequentially stacked on the upper surface of a substrate 5201. These electrode layers and insulating layers are formed over the entire length of the sensor probe portion 521 or over a portion of the length, and over the entire width in the direction perpendicular to the length. With the electrode layers and insulating layers stacked in this manner, both side surfaces in the width direction are finished by cutting along the cutting lines shown by dotted lines in Figure 46(a). Through this cutting process, both side surfaces in the width direction of the sensor probe portion 521 become smooth, as shown in Figure 46(b).
[0183] However, in the actual manufacturing process, when cutting both sides in the width direction, the first electrode layer 5202 and the second electrode layer 5204 come into contact with each other due to being pushed out by the cutting blade, resulting in an electrical connection problem. This problem occurs frequently, especially since the electrode layers and insulating layers are formed with extremely fine thicknesses in the micron range. The first electrode layer 5202 and the second electrode layer 5204 can function as a normal sensor only if they are completely separated by the first insulating layer 5203 between them. However, if the first electrode layer 5202 and the second electrode layer 5204 come into contact with each other during the side cutting process, the sensor will not function properly and the product will be rejected.
[0184] In order to prevent such a problem, one embodiment of the present invention has a laminated structure as shown in Fig. 47. That is, the first electrode layer 5202 and the second electrode layer 5204 are arranged alternately so that one of the first electrode layer 5202 and the second electrode layer 5204 is exposed on one side of both sides in the width direction of the sensor probe part 521 and the other is exposed on the other side.
[0185] 47(a), the first electrode layer 5202 is stacked on the substrate 5201 so as to be offset to the left in the width direction of the upper surface of the substrate 5201, and the first insulating layer 5203 is stacked on the substrate 5201 and the first electrode layer 5202 so as to surround the upper and side surfaces of the first electrode layer 5202. The second electrode layer 5204 is stacked on the upper surface of the first insulating layer 5203 so as to be offset to the right in the width direction of the substrate 5201. The second insulating layer 5205 is stacked on the first insulating layer 5203 and the second electrode layer 5204 so as to surround the upper and side surfaces of the second electrode layer 5204.
[0186] With the electrode layers and insulating layers stacked in this manner, both widthwise side surfaces are cut along the cutting lines shown by dotted lines in Fig. 47(a) to finish forming the sensor probe part 521. Through this cutting process, the first electrode layer 5202 is exposed on one side surface and the second electrode layer 5204 is exposed on the other side surface of the sensor probe part 521 in the widthwise direction, as shown in Fig. 47(b).
[0187] In this case, unlike the stacked structure shown in FIG. 46, the stacked structure shown in FIG. 47 has the first electrode layer 5202 and the second electrode layer 5204 stacked so that they cross each other. Therefore, even if the first electrode layer 5202 and the second electrode layer 5204 are pushed out by the cutting blade during the process of cutting both sides in the width direction, the first electrode layer 5202 and the second electrode layer 5204 do not come into contact with each other, thereby significantly reducing the rate of product defects.
[0188] 48, a separate third electrode layer 5206 may be formed on the lower surface of one end of the substrate 5201, and a third insulating layer 5207 may be laminated on the substrate 5201 and the third electrode layer 5206 to surround the lower surface of the third electrode layer 5206. Since the third electrode layer 5206 is laminated on the lower surface of the substrate 5201 differently from the first and second electrode layers 5202 and 5204, the third electrode layer 5206 does not come into contact with the first and second electrode layers 5202 and 5204 during the cutting process of both sides, and therefore, the third electrode layer 5206 may be formed over the entire widthwise region of the lower surface of the substrate 5201 or only in the central region as shown in FIG.
[0189] Of course, if two electrode layers are sequentially stacked on the lower surface of the substrate 5201, it is desirable to stack them so that they are arranged to cross each other, just like the first electrode layer 5202 and the second electrode layer 5204.
[0190] When two electrode layers are formed on the sensor element, each electrode layer can function as a working electrode and a counter electrode, and when three electrode layers are formed, each electrode layer can function as a working electrode, a counter electrode, and a reference electrode. In addition, more electrode layers can be formed, and each can be used to measure different substances.
[0191] In addition, the first electrode layer 5202 and the second electrode layer 5204 may be formed over the entire length of the sensor probe portion 521 of the sensor member 520 and may be extended to the sensor body portion 522 so as to contact the electrical contacts of the PCB substrate.
[0192] The above description is merely illustrative of the technical concept of the present invention, and various modifications and variations may be made by those skilled in the art without departing from the essential characteristics of the present invention.
