Description

[Technical Field]

[0001] The present invention relates to a continuous blood glucose measuring device. More specifically, the present invention relates to a continuous blood glucose measuring device that supplies power to a body-attachable unit and starts its operation through a user's operation, such as by removing a protective cap while the body-attachable unit is inside an applicator. This allows the body-attachable unit to be started at an appropriate time by the user's operation just before the body is inserted and attached to the body, and improves usability by simply removing the protective cap without requiring any additional steps to start the body-attachable unit. The present invention also relates to a continuous blood glucose measuring device that can be manufactured and used more conveniently by implementing various methods for operating a power supply switch means that supplies battery power to the body-attachable unit in response to the protective cap removal operation. [Background technology]

[0002] Diabetes is a chronic disease that commonly affects people today, affecting over 2 million people in Japan, or 5% of the total population.

[0003] Diabetes develops 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 balance of sugar in the blood from being corrected, resulting in an absolute excess of sugar in the blood.

[0004] Blood normally contains a certain concentration of glucose, from which tissue cells obtain energy.

[0005] However, if glucose levels increase more than necessary, they are not properly stored in the liver, muscles, or fat cells, and instead accumulate in the blood. This causes diabetics to 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, and causing abnormalities in each tissue.

[0006] Diabetes is characterized by having almost no noticeable symptoms in the early stages, but as the disease progresses, symptoms specific to diabetes such as excessive drinking, eating, urination, weight loss, general fatigue, itchy skin, and persistent or prolonged wounds on the hands and feet appear.As the disease progresses further, complications appear, including vision impairment, high blood pressure, kidney disease, stroke, periodontal disease, muscle spasms and neuralgia, and gangrene.

[0007] In order to diagnose this type of diabetes and manage it so that it does not progress to complications, systematic blood glucose measurement and treatment must be carried out in parallel.

[0008] For people with diabetes and those who do not have 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 monitor their blood sugar at home.

[0009] There are two types of blood glucose monitors: one in which the user draws blood from the fingertip and measures blood glucose one time, and one in which the monitor is attached to the user's abdomen, arm, etc. and measures blood glucose continuously.

[0010] Diabetic patients generally go back and forth between hyperglycemia and hypoglycemia, and emergency situations occur during hypoglycemia, which can lead to loss of consciousness or death if the hypoglycemia persists for a long time without receiving sugar. Therefore, it is very important for diabetics to detect hypoglycemia immediately, but blood glucose meters that measure blood glucose levels intermittently have limitations in accurately detecting this.

[0011] In recent years, to overcome these limitations, continuous glucose monitoring systems (CGMS) have been developed that are inserted into the human body and measure blood glucose levels every few minutes, making it easier to manage diabetic patients and respond to emergency situations.

[0012] In addition, blood glucose meters require diabetics to test their blood sugar levels by pricking their fingertips with a needle, which is sensitive to pain, causing pain and discomfort during the blood sampling process. To minimize this pain and discomfort, research and development is underway on continuous blood glucose monitoring systems that measure blood sugar continuously by inserting a needle-shaped sensor into areas where pain is less likely, such as the abdomen or arm. Furthermore, active research and development is also underway on non-invasive glucose monitoring systems that measure blood sugar without sampling blood.

[0013] Over the past 40 years, research has been conducted into various methods for non-invasive blood glucose monitoring, including optical, electrical, and breath-based methods, to measure blood glucose without drawing blood. Cygnus (Redwood City, CA, USA) developed and released the wristwatch-type Glucowatch G2 Biographer using reverse iontophoresis, but sales were discontinued in 2007 due to issues such as skin irritation, calibration issues, the device shutting down during sweating, and an inability to accurately detect hypoglycemia compared to hyperglycemia. While many blood-free blood glucose monitoring technologies have been reported to date, they have not been put to practical use due to their lack of accuracy.

[0014] The continuous blood glucose monitoring device includes a sensor module that is inserted into and attached to the skin of the body to extract body fluids and measure blood glucose, a transmitter that transmits the blood glucose value measured by the sensor module to a terminal, and a terminal that outputs the transmitted blood glucose value. 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 insert and attach the sensor module to the body.

[0015] Such continuous blood glucose monitoring devices are manufactured in a wide variety of forms by different manufacturers, and their usage methods are also varied. However, most continuous blood glucose monitoring devices are manufactured and distributed in a manner in which a disposable sensor module is inserted and attached to the body via an applicator, and users must perform several steps to operate the applicator to attach the disposable 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 the disposable sensor module must be removed and accurately inserted into the applicator, and with the sensor module inserted in the applicator, the applicator must be activated to insert the sensor module into the skin, and after insertion, the needle of the sensor module must be directly pulled out of the skin using a separate tool, and another transmitter must be connected to the sensor module to transmit the blood glucose measurement results to the user terminal.

[0017] Therefore, there is a problem that the operation of measuring blood glucose using a continuous blood glucose monitoring device is very troublesome and inconvenient, and there is also a problem that the user does not initiate the operation of the sensor module and transmitter, which reduces the accuracy of the blood glucose measurement results and shortens the life of the device. Summary of the Invention [Problem to be solved by the invention]

[0018] The present invention was invented to solve the problems of the prior art, and its object is to provide a continuous blood glucose measuring device that improves usability by supplying power to the body-attachable unit and starting its operation through a user operation, such as removing and separating a protective cap, while the body-attachable unit is inside the applicator, so that the start of operation of the body-attachable unit can be performed by the user operation just before inserting and attaching it to the body, and the body-attachable unit can be started at an appropriate time.In addition, there is no need to perform any additional steps to start the body-attachable unit, as the body-attachable unit can be started by simply removing the protective cap.

[0019] Another object of the present invention is to provide a continuous blood glucose measuring device that can be manufactured and used more conveniently by implementing various methods for operating the power supply switch means, which supplies battery power to the body-attachable unit, in conjunction with the protective cap removal operation. [Means for solving the problem]

[0020] The present invention provides a continuous blood glucose measuring device including: a body-attachable unit that is insertable and attachable to the body so as to periodically measure blood glucose levels; and an applicator to which the body-attachable unit is attached and fixed, and which operates by a user to insert and attach the body-attachable unit to the body and to eject the body-attachable unit to the outside, wherein a battery for power supply is built into the body-attachable unit, and the body-attachable unit is placed inside the applicator and starts operating when power is supplied from the battery by a user's operation.

[0021] In this case, the applicator may be provided with a protective cap detachably coupled thereto to block exposure of the body-attachable unit disposed therein to the outside, and a power supply switch means that operates to supply power from the battery to the body-attachable unit in conjunction with the detachment and removal of the protective cap.

[0022] In addition, the applicator may be configured such that the protective cap prevents the body attachment unit from being discharged to the outside when the protective cap is attached to the applicator.

[0023] The body-attachable unit further includes a housing whose bottom surface is formed to attach to the skin, a PCB board disposed inside the housing so as to be electrically connected to the battery, and a sensor member disposed inside the housing so that one end protrudes outward from the bottom surface of the housing and is electrically connected to the PCB board, and the power supply switch means operates to supply power from the battery to the PCB board when the protective cap is separated and removed.

[0024] In addition, the power supply switch means includes a board contact formed on the PCB board, a battery contact connected to the battery, and a switch terminal movably attached inside the housing so as to contact the board contact and the battery contact simultaneously, and the switch terminal can move to contact the board contact and the battery contact simultaneously in conjunction with the separating and removing operation of the protective cap, thereby electrically connecting them to each other.

[0025] The power supply switch means may further include an elastic member that applies an elastic force to the switch terminal in a direction in which the switch terminal simultaneously contacts the board contact and the battery contact, and an actuation protrusion that protrudes from one surface of the protective cap and presses the switch terminal so that the switch terminal is separated from the board contact and the battery contact when the protective cap is coupled to the applicator.

[0026] In addition, an insertion guide portion may be formed on the bottom surface of the housing, protruding inward to guide the actuation protrusion of the protection cap.

[0027] A blocking film made of a ductile material may be disposed on the protruding end of the insertion guide portion, and may be deformed by the actuation protrusion to block the internal space of the housing from the outside.

[0028] In addition, the power supply switch means may include a switch element that electrically connects or disconnects the battery and the PCB board in response to an electrical signal input to an enable terminal; a switch contact having one end grounded and the other end connected to the enable terminal; and a connection terminal formed on one side of the protective cap for electrically connecting or disconnecting one end of the switch contact to the other end depending on whether the protective cap is detached or removed. When the connection terminal electrically connects one end of the switch contact to the other end, a low electrical signal is input to the enable terminal, and when the connection terminal electrically disconnects one end of the switch contact from the other end, a high electrical signal is input to the enable terminal by the power supply of the battery.

[0029] In addition, the switch contact may be formed to be located in the internal space of the housing, an actuation protrusion protruding toward the switch contact may be formed on one side of the protective cap, the connection terminal may be formed at a tip of the actuation protrusion, and an insertion guide portion protruding inward may be formed on the bottom surface of the housing to guide the actuation protrusion of the protective cap into insertion. [Effects of the Invention]

[0030] According to the present invention, power is supplied to the body-attachable unit and it is activated by a user operation such as removing and separating the protective cap while the body-attachable unit is inside the applicator. This allows the body-attachable unit to be activated at the appropriate time by the user operation just before it is inserted and attached to the body, and there is no need to perform any additional steps to activate the body-attachable unit; simply removing the protective cap activates the body-attachable unit, thereby improving convenience of use.

[0031] In addition, the operation method of the power supply switch means that supplies battery power to the body-attachable unit can be formed in various ways linked to the separation and removal operation of the protective cap, which has the effect of further improving the convenience of manufacturing and use.

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, when assigning reference numerals to components in each drawing, it should be noted that the same components are assigned the same numerals as much as possible even if they appear in different drawings. Furthermore, in the description of the present invention, if it is determined that a detailed description of related known structures or functions may obscure the gist of the present invention, the detailed description will be omitted.

[0034] FIG. 1 is a diagram showing a schematic diagram of a basic system of a continuous blood glucose measuring device according to one embodiment of the present invention, FIG. 2 is a diagram showing a schematic diagram of an applicator shape of a continuous blood glucose measuring device according to one embodiment of the present invention, and FIG. 3 is a diagram showing a schematic diagram of a configuration of a body-attachable unit of a continuous blood glucose measuring device according to one embodiment of the present invention.

[0035] A continuous blood glucose measuring device according to one embodiment of the present invention is configured to attach a body-attachable unit 20 having a sensor member 520 to be inserted into the body for continuous blood glucose measurement to the body via an applicator 10, and to insert and attach the body-attachable unit 20 to the body by activating the applicator 10 to periodically and continuously measure blood glucose from the body, and to transmit and output blood glucose measurement information periodically measured via the body-attachable unit 20 to another terminal 30.

[0036] The body-attachable unit 20 can be assembled inside the applicator 10 to be manufactured as a single unit product, in which case the user's additional work during use of the continuous blood glucose monitoring device is minimized, resulting in a very simple structure for use. Of course, the body-attachable unit 20 can be supplied to the user separately from the applicator 10, and the user can insert the body-attachable unit 20 into the applicator 10 to operate it, or in other ways.

[0037] The body-attachable unit 20 is configured to be attachable to the body so that it can extract body fluids and periodically measure blood glucose, and is also configured so that it can transmit blood glucose measurement results to an external device such as an external terminal 30. Such a body-attachable unit 20 may include a sensor member 520, one end of which is inserted into the body, and a wireless communication chip (not shown) capable of wireless communication with the external terminal 30.

[0038] The applicator 10 is formed so that the body attachment unit 20 is fixedly connected thereto, and is operated so as to discharge the body attachment unit 20 to the outside when the user applies pressure to the pressure button 110 .

[0039] In this case, the body attachment unit 20 is assembled and manufactured in a state where it is inserted inside the applicator 10, and is configured to move in the direction of external discharge and attach to the body in response to the operation of the applicator 10 by the user's operation.

[0040] That is, the sensor applicator assembly according to one embodiment of the present invention is assembled and manufactured in a manner 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 during the manufacturing process, and can be supplied to the user in this state, allowing the user to 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, eliminating the need to connect a separate transmitter and making it more convenient to use.

[0041] A separate protective cap 200 may be detachably coupled to the applicator 10 so that the body-attachable unit 20 is blocked from exposure to the outside when inserted inside the applicator 10, and the user may be configured to separate the protective cap 200 and then activate the applicator 10 to eject the body-attachable unit 20 externally onto the side from which the protective cap 200 was removed, thereby attaching it to the body.

[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 adheres to the body, and a release paper (not shown) is attached to the body contact surface of the adhesive tape 560 to protect the adhesive tape 560, but the release paper of the adhesive tape 560 may 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] The applicator 10 may be configured to fasten the body attachment unit 20 when the body attachment unit 20 is inserted inside, and to release the fastened state of the body attachment unit 20 when the body attachment unit 20 is discharged and moved to the outside. Therefore, when the body attachment unit 20 is inserted and assembled inside the applicator 10, the body attachment unit 20 remains fixed, and when the applicator 10 is actuated to discharge the body attachment unit 20 to the outside and attach it to the skin, the fastened state of the applicator 10 and the body attachment unit 20 is released. Therefore, when the applicator 10 is separated in this state, it is separated from the body attachment unit 20, and only the body attachment unit 20 remains attached to the skin.

[0044] The body-attachable unit 20 is formed such that a sensor member 520 is disposed inside a separate housing 510, and one end of the sensor member 520 protrudes from the bottom surface of the housing 510 to be inserted into and attached to the body. The sensor member 520 is composed of a sensor probe portion 521 (see FIG. 5) that is inserted into the body, and a sensor body portion 522 (see FIG. 5) that is disposed inside the housing 510, and the sensor probe portion and the sensor body portion are bent to form one end and the other end of the sensor member 520, respectively.

[0045] At this time, to facilitate the process of inserting the sensor member 520 into the body, a separate guide needle 550 may be detachably coupled to the housing 510. The guide needle 550 is configured to enclose one end of the sensor member 520 so that one end of the sensor member 520 is stably inserted into the body, and to be inserted into the body together with the sensor member 520.

[0046] 2, the guide needle 550 is detachably attached to the housing 510 of the body-attachable unit 20 in a direction that penetrates the housing 510 vertically, is formed in a shape that surrounds the outside of the sensor member 520, and has 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 guide needle 550 is inserted into the body before the sensor member 520, and guides the sensor member 520 so that it is stably inserted into the skin. The guide needle 550 is coupled to a needle withdrawal means (not shown) of the applicator 10 via the needle head 551, and is formed so that after the body-attachable unit 20 is inserted into and attached to the body by operation of the applicator 10, it can be withdrawn and removed from the body by the needle withdrawal means of the applicator 10.

[0047] FIG. 4 is a diagram illustrating the process of inserting the body attachment unit into the body via an applicator according to one embodiment of the present invention, and FIGS. 5 and 6 are diagrams illustrating the connection structure between the body attachment unit and the protective cap according to one embodiment of the present invention.

[0048] As described above, the applicator 10 according to one embodiment of the present invention is a device that operates by inserting and attaching the body-attachable unit 10 to the body through user operation, and may include a main case 100 with one open side, a plunger body 300 that moves from the inside of the main case 100 toward the open side in a direction of discharging outward, and a plunger elastic spring S1 that applies an elastic force to the plunger body 300 so that the plunger body 300 moves in a direction of discharging outward, and the body-attachable unit 10 may be connected to the plunger body 300 and configured to move together with the plunger body 300 in a direction of discharging outward.

[0049] An operating unit such as a pressure button (not shown) that can be operated by the user is provided on the outside of the main case 100, and the plunger body 300 is coupled and fixed to a first position inside the main case 100. In response to operation of the operating unit, the coupled and fixed state is released from the first position and moves linearly to a second position in the direction of external discharge by the elastic force of the plunger elastic spring S1. The body-attachable unit 10 is coupled to one end of the plunger body 300 and moves linearly together with the plunger body 300 in the direction of external discharge, and is inserted and attached to the body skin E.

[0050] As described above, the body-attachable unit 10 includes the housing 510, the sensor member 520 including the sensor body portion 522 and the sensor probe portion 521, and the guide needle 550 that is disposed so as to externally enclose the sensor probe portion 521 and is detachably coupled to the housing 510. A PCB board 530 and a battery 535 are attached inside the housing 510 to supply power to the PCB board 530. A wireless communication chip (not shown) for communicating with an external terminal is attached to the PCB board 530, and the sensor member 520 is electrically connected to the PCB board 530 via electrical contacts 531.

[0051] When the body-attachable unit 10 is discharged to the outside, the sensor probe portion 521 of the sensor member 520 is positioned to protrude outward from the bottom surface of the housing 510 so that the sensor probe portion 521 is inserted into the body skin E, and the guide needle 550 wraps around the sensor probe portion 521 from the outside and is inserted into the body skin E together with the sensor probe portion 521.

[0052] After being inserted into the body skin E, the guide needle 550 is withdrawn and removed from the skin E, and the applicator 10 is provided with a needle withdrawal means N that withdraws and removes the guide needle 550 from the body skin E while the guide needle 550 is inserted into the body skin E.

[0053] The needle puller means N may include a needle puller body 400 that is engaged with the plunger body 300, moves linearly together with the plunger body 300 in the external discharge direction, and is engaged with a needle head 551 formed at the upper end of the guide needle 550, and a needle puller elastic spring S2 that applies elastic force to the needle puller body 400 in the direction opposite to the external discharge direction. The plunger body 300 is formed with a hook engaging portion 350 that can restrict the elastic movement of the needle puller body 400, and an elastic hook 410 that is engaged with the hook engaging portion 350 is formed on the upper part of the needle puller body 400. The elastic hook 410 engages with the hook engaging portion 350, and the needle withdrawal body 400 moves together with the plunger body 300 in the external discharge direction. When the needle withdrawal body 400 moves a predetermined distance, the engagement between the elastic hook 410 and the hook engaging portion 350 is released by another release means (not shown), and in this state the needle withdrawal body 400 moves upward in the opposite direction to the external discharge direction by the needle withdrawal elastic spring S2.

[0054] That is, as shown in Fig. 4(a), after the protective cap 200 is removed from the applicator 10 and the applicator 10 is attached to the skin, when the pressure button 110 is pressed, the body-attached unit 20 is ejected to the outside together with the plunger body 300, and the end of the sensor member 520 is inserted into the skin, as shown in Fig. 4(b). At the same time, as shown in Fig. 4(c), the guide needle 550 is pulled out and removed from the skin by the needle pulling means N. Thereafter, when the applicator 10 is removed from the skin, only the body-attached unit 20 remains attached to the skin, and blood glucose is measured periodically in this state.

[0055] As described above, in the continuous blood glucose measuring device according to one embodiment of the present invention, the protective cap 200 is attached to the applicator 10 while the body-attachable unit 20 is placed inside the applicator 10. After removing the protective cap 200, the body-attachable unit 20 can be ejected to the outside by pressing the pressure button of the applicator 10, and then inserted and attached to the body.

[0056] In this case, the applicator 10 may be formed so that an operation to discharge the body attachment unit 20 to the outside, specifically, an operation to pressurize the pressure button, is prevented by the protective cap 200 when the protective cap 200 is coupled to the applicator 10. For example, the protective cap 200 may be formed with a separate locking protrusion to restrict the pressure movement of the pressure button when coupled to the applicator 10.

[0057] Meanwhile, the continuous blood glucose measuring device according to an embodiment of the present invention may be configured to start operation by supplying power from the battery 535 through a user's operation while the body-attachable unit 20 is placed inside the applicator 10. That is, the device may be configured so that power from the battery 535 is supplied to the body-attachable unit 20 through a user's operation before the body-attachable unit 20 is discharged to the outside from the applicator 10.

[0058] For this purpose, a power supply switch means PS may be provided which operates to supply power from the battery 535 to the body attachment unit 20 in conjunction with the separating and removing operation of the protective cap 200.

[0059] As described above, the body-attachable unit 20 includes a housing 510, a PCB board 530, and a sensor member 520. A battery 535 that can be electrically connected to the PCB board 530 is attached inside the housing 510. At this time, the power supply switch means PS operates so that power is supplied from the battery 535 to the PCB board 530 when the protective cap 200 is separated and removed.

[0060] As shown in FIGS. 5 and 6, an actuation protrusion 205 is formed on one side of the protective cap 200, and an insertion guide portion 513 may be formed on the housing 510 of the body attachment unit 20 to guide the actuation protrusion 205 for insertion. Using electrical elements etc. that operate through this mechanical configuration, as shown in FIG. 6, when the protective cap 200 is separated and removed, the power supply switch means PS is operated to supply power to the PCB board 530.

[0061] In this way, power is supplied to the body-attachable unit 20 and it starts operating by a user operation such as removing and separating the protective cap 200 while the body-attachable unit 20 is inside the applicator 10. As a result, the start of operation of the body-attachable unit 20 is determined by the user operation just before it is inserted and attached to the body, so that the body-attachable unit 20 can be started at the appropriate time. In particular, there is no need to perform any additional steps to start the operation of the body-attachable unit 20; simply removing the protective cap 200 starts the operation of the body-attachable unit 20, further improving convenience of use.

[0062] Next, the power supply switch means PS according to one embodiment of the present invention will be described in more detail.

[0063] FIG. 7 is a conceptual diagram conceptually showing the configuration of a power supply switch means according to a first embodiment of the present invention, and FIG. 8 is a diagram schematically showing the configuration for realizing the power supply switch means shown in FIG.

[0064] The power supply switch means PS1 according to the first embodiment of the present invention includes a board contact 501 formed on a PCB board 530, a battery contact 502 connected to a battery 535, and a switch terminal 503 movably mounted inside a housing 510 so as to be able to contact the board contact 501 and the battery contact 502 simultaneously, and the switch terminal 503 is configured to move to be able to contact the board contact 501 and the battery contact 502 simultaneously in conjunction with the separating and removing operation of the protective cap 200, thereby electrically connecting them to each other.

[0065] In this case, an elastic member 5031 that applies an elastic force to the switch terminal 503 in a direction in which the switch terminal 503 simultaneously contacts the board contact 501 and the battery contact 502 may be disposed inside the housing 510, and an actuation protrusion 205 that presses the switch terminal 503 so that the switch terminal 503 moves away from the board contact 501 and the battery contact 502 when the protective cap 200 is coupled to the applicator 10 may be formed protruding from one side of the protective cap 200.

[0066] As shown in Figures 7(a) and 8(a), when the protective cap 200 is coupled to the applicator 10, the actuation protrusion 205 presses the switch terminal 503, causing the switch terminal 503 to be positioned away from the board contact 501 and the battery contact 502, so that the board contact 501 and the battery contact 502 are not connected to each other and therefore battery power is not supplied to the PCB board 530.

[0067] 7(b) and 8(b), when the user wishes to insert and attach the body-attachable unit 20 to their body, the protective cap 200 must be separated and removed from the applicator 10. When the protective cap 200 is separated and removed, the actuation protrusion 205 releases pressure on the switch terminal 503, causing the switch terminal 503 to move due to the elastic force of the elastic member 5031 and simultaneously come into contact with the board contact 501 and the battery contact 502. As a result, the board contact 501 and the battery contact 502 are electrically connected to each other by the switch terminal 503, battery power is supplied to the PCB board 530, and the body-attachable unit 20 begins to operate.

[0068] At this time, an insertion guide portion 513 protruding inward may be formed on the bottom surface of the housing 510 so as to guide the insertion of the actuating protrusion 205 of the protective cap 200. In addition, a barrier film 514 made of a ductile material may be attached to the protruding end of the insertion guide portion 513 so as to isolate the internal space of the housing 510 from the outside. The barrier film 514 serves to provide a waterproof function for the internal space of the housing 510 and may be made of a ductile material that can be deformed by pressure caused by the actuating protrusion 205.

[0069] FIG. 9 is a conceptual diagram conceptually showing the configuration of a power supply switch means according to a second embodiment of the present invention, and FIG. 10 is a diagram schematically showing the configuration for realizing the power supply switch means shown in FIG.

[0070] The power supply switch means PS2 according to the second embodiment of the present invention may include a switch element 504 that electrically connects or disconnects a battery 535 and a PCB board 530 in response to an electrical signal input to an enable terminal 5041, a switch contact 505 having one end grounded and the other end connected to the enable terminal 5041, and a connection terminal 506 formed on one side of the protective cap 200 and electrically connecting or disconnecting one end of the switch contact 505 depending on whether the protective cap 200 is detachable or removable. When the connection terminal 506 electrically connects one end of the switch contact 505 to the other end, a low electrical signal is input to the enable terminal 5041, and when the connection terminal 506 electrically disconnects one end of the switch contact 505 from the other end, a high electrical signal is input to the enable terminal 5041 by power from the battery 535. The switch contact 505 may be formed to be located in the internal space of the housing 510, and the connection terminal 506 may be formed at the tip of an actuation protrusion 205 of the protective cap 200.

[0071] As shown in Figures 9(a) and 10(a), when the protective cap 200 is coupled to the applicator 10, the connection terminal 506 of the actuating protrusion 205 is connected to and contacts the switch contact 505, electrically connecting one end and the other end of the switch contact 505, and as shown in Figures 9(b) and 10(b), when the protective cap 200 is separated and removed from the applicator 10, the connection terminal 506 of the actuating protrusion 205 is separated from the switch contact 505, electrically disconnecting one end and the other end of the switch contact 505.

[0072] When one end of the switch contact 505 is electrically connected to the other end by the connection terminal 506, a low electrical signal is input to the enable terminal 5041 of the switch element 504, and in this case, the switch element 504 operates to electrically disconnect the battery 535 from the PCB board 530. Therefore, power from the battery 535 is not supplied to the PCB board 530.

[0073] When the connection terminal 506 is separated from one end and the other end of the switch contact 505, the one end and the other end of the switch contact 505 are electrically disconnected, and a high electrical signal is input to the enable terminal 5041 of the switch element 504. In this case, the switch element 504 operates to electrically connect the battery 535 and the PCB board 530, and power from the battery 535 is supplied to the PCB board 530, causing the body-attachable unit 20 to start operating.

[0074] The operating methods of these switch contacts 505 and switch element 504 are merely exemplary, and various other methods are applicable. As the switch element 504, a TR (transistor), a FET (field effect transistor), an analog switch IC, etc. can be applied.

[0075] The above description merely exemplifies the technical concept of the present invention, and various modifications and variations are possible within the scope of the essential characteristics of the present invention, provided that such modifications and variations are made by a person skilled in the art to which the present invention pertains. Therefore, the embodiments disclosed in the present invention are intended to illustrate, rather than limit, the technical concept of the present invention, and the scope of the technical concept of the present invention is not limited by such embodiments. The scope of protection of the present invention should be interpreted by the following claims, and all technical concepts within the same scope should be interpreted as being within the scope of the rights of the present invention.
