Description

TECHNICAL FIELD

[0001] The present application relates to a continuous blood glucose measurement device. In more detail, the present application relates to a continuous blood glucose measurement device in which the start time point of the operation of a body attachment unit is formed by a user's operation before insertion into the body, so that the body attachment unit can start the operation at an appropriate time point, and even if a separate additional work for starting the operation of the body attachment unit is not performed, the body attachment unit can start the operation only by removing a protective cap to improve the convenience of use, and by forming the operation mode of a power supply switch mechanism for supplying the battery power to the body attachment unit in a plurality of modes linked to the operation of separating and removing the protective cap, the convenience of production and use can be further improved. BACKGROUND

[0002] Diabetes is a chronic disease that occurs frequently in modern people, and in Korea, more than 2 million people, i.e., 5% of the total population, have diabetes.

[0003] Diabetes is a disease that occurs due to an absolute or relative deficiency of insulin produced by the pancreas due to obesity, stress, wrong eating habits, congenital inheritance, etc., and cannot correct the balance of sugar in the blood, resulting in an absolute increase in the sugar component in the blood.

[0004] Blood usually contains a certain concentration of glucose, and tissue cells obtain energy therefrom.

[0005] However, when the glucose is increased more than necessary, it cannot be properly stored in the liver or muscle or adipocyte, etc., and is accumulated in the blood, and thus, the blood sugar of a diabetic patient is maintained much higher than that of a normal person, and as excessive blood sugar is directly discharged through the tissues as urine, the sugar absolutely required by each tissue of the body becomes insufficient, thereby causing abnormalities in each tissue of the body.

[0006] Diabetes is characterized in that there are almost no subjective symptoms in the early stage, but as the disease progresses, symptoms specific to diabetes such as polydipsia, polyphagia, polyuria, weight loss, general fatigue, skin itching, and long-lasting non-healing of wounds on the hands and feet, etc., occur, and when the disease further progresses, complications such as visual impairment, hypertension, nephropathy, stroke, periodontal disease, muscle spasm, neuralgia, gangrene, etc., develop.

[0007] In order to diagnose such diabetes and manage it so that it does not develop into a complication, blood glucose measurement and treatment should be performed in parallel.

[0008] For diabetic patients and people who have not developed diabetes but have more than normal sugar in their blood, many medical instrument manufacturers provide a variety of blood glucose meters to enable blood glucose measurement at home.

[0009] The blood glucose meter is used in a manner in which a user takes blood from a fingertip and performs blood glucose measurement in a unit of time, and in a manner in which a continuous blood glucose measurement is performed by attaching a sensor to the abdomen or arm of the user.

[0010] For diabetic patients, it is common to alternate between hyperglycemia and hypoglycemia, and emergency situations arise from hypoglycemia, and when loss of consciousness or hypoglycemia continues for a long time without sugar supply, there is also a risk of death. Therefore, it is extremely important for diabetic patients to immediately find hypoglycemia, but blood sampling blood glucose meters that intermittently measure blood glucose have limitations in accurately grasping the blood glucose state.

[0011] Recently, in order to overcome such limitations, a continuous blood glucose monitoring system (CGMS) that measures blood glucose values at intervals of several minutes by being inserted into the human body has been developed, and using the same, it is possible to easily manage diabetic patients and respond to emergency situations.

[0012] In addition, since the blood sampling blood glucose meter performs blood glucose measurement in a manner in which a diabetic patient uses a needle to pierce a fingertip sensitive to pain to collect blood in order to check his or her own blood glucose, pain and resistance are caused during blood sampling. In order to minimize such pain and resistance, research and development of a continuous blood glucose measurement system that continuously measures blood glucose after inserting a needle-shaped sensor into a site such as the abdomen or arm, which is relatively less sensitive to pain, is being conducted, and further, development of a non-invasive blood glucose measurement system (Non-Invasive Glucose Monitoring System) that measures blood glucose without collecting blood is actively being conducted.

[0013] For the non-invasive blood glucose measurement system, in the past 40 years, in order to measure blood glucose without collecting blood, research has been conducted on various methods such as an optical method, an electrical method, measurement in exhaled breath, etc. Cygnus (Redwood City, California, USA) developed and marketed Glucowatch G2 Biographer in the form of a wristwatch using a counter-ion electro-osmosis method, but sales were discontinued in 2007 due to problems with skin irritation and authentication, a problem in which the device stops when sweating, a problem in which hypoglycemia is not well recognized relative to hyperglycemia, etc. Although many non-blood sampling blood glucose measurement techniques have been developed and reported to date, they have not been practically used due to low accuracy.

[0014] A continuous blood glucose measurement device includes a sensor module inserted to adhere to the skin of a body to measure blood glucose by extracting body fluid, a transmitter that transmits a blood glucose value measured by the sensor module to a terminal, and a terminal that outputs the received blood glucose value, and the like. In the sensor module, a sensor probe formed in a needle shape to be inserted into subcutaneous fat and extract interstitial fluid, and the like are provided, and a separate applicator is used to insert the sensor module to adhere to the body.

[0015] Such a continuous blood glucose measurement device is manufactured in a very diverse form by each manufacturer, and the usage thereof is also diverse. However, most of the continuous blood glucose measurement devices are manufactured and circulated in a manner that a disposable sensor module is inserted to adhere to the body through an applicator, and in order for the operation of the applicator for adhering the disposable sensor module to the body, the user needs to perform a plurality of steps of work, and after the sensor module is adhered to the body, a variety of subsequent procedures such as directly pulling out a needle are required.

[0016] For example, it is necessary to peel off the package of the disposable sensor module and accurately insert it into the applicator, and it is necessary to perform work of starting the applicator to insert the sensor module into the skin in a state in which the sensor module is inserted into the applicator, and directly pulling out the needle of the sensor module from the skin using a separate instrument after insertion, and in order to transmit the blood glucose measurement result to the user terminal, it is necessary to perform work of coupling a separate transmitter to the sensor module.

[0017] Therefore, there is a problem that the work for measuring blood glucose using the continuous blood glucose measurement device is very cumbersome and inconvenient. In addition, since the work start of the sensor module and the transmitter is not performed by the user, there is a problem that the accuracy of the blood glucose measurement result is reduced and the life of the device is reduced, and the like.

[0044] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings. First, when numerals are added to the components of each drawing, the same numerals are added, as much as possible, to the same components even if they are shown in different drawings. Also, in describing the present application, when it is determined that a detailed description of a related known component or function can obscure the gist of the present application, the detailed description thereof will be omitted.

[0045] Figure 1 ​​FIG. 1 is a diagram schematically showing a basic system of a continuous blood glucose measurement device of an embodiment of the present application, Figure 2 FIG. 2 is a diagram schematically showing the shape of an applicator of a continuous blood glucose measurement device of an embodiment of the present application, Figure 3 FIG. 3 is a diagram schematically showing the structure of a body attachment unit of a continuous blood glucose measurement device of an embodiment of the present application.

[0046] The continuous blood glucose measurement device of an embodiment of the present application is configured to attach the body attachment unit 20 provided with the sensor part 520 inserted into the body for continuously measuring blood glucose to the body through the applicator 10, and is configured to operate the applicator 10 to insert the body attachment unit 20 into the body to be attached and continuously measure blood glucose from the body periodically, and the blood glucose measurement information periodically measured through the body attachment unit 20 is transmitted to the separate terminal 30 to be output.

[0047] The body attachment unit 20 can be assembled to the inside of the applicator 10 to be manufactured as one unit product, in which case, it is formed in a form to minimize the additional work of the user when using the continuous blood glucose measurement device to make the use mode very simple structure. Of course, it can be manufactured in various ways, such as being supplied to the user separately from the applicator 10, and being inserted into the inside of the applicator 10 by the user to operate it, etc.

[0048] The body attachment unit 20 is formed to be attachable to the body in a manner capable of extracting body fluid and periodically measuring blood glucose, and is formed to be capable of transmitting the blood glucose measurement result to an external device such as the external terminal 30. In such a body attachment unit 20, a sensor part 520 having one end inserted into the body and a wireless communication chip (not shown) capable of wireless communication with the external terminal 30 can be provided inside.

[0049] The applicator 10 is formed to incorporate and fix the body attachment unit 20 inside, and is operated in a manner to discharge the body attachment unit 20 to the outside by the pressing operation of the pressing button 110 by the user.

[0050] At this time, the body attachment unit 20 is assembled and manufactured in a state of being inserted into the inside of the applicator 10, and is configured to move in the direction of external discharge to be attached to the body as the operation of the applicator 10 by the user's operation.

[0051] That is, the sensor applicator assembly of one embodiment of the present application is assembled and manufactured in a state in which the body attachment unit 20 is inserted into the inside of the applicator 10, and only by the operation of the applicator 10, the body attachment unit 20 is attached to the skin, and can be supplied to the user in this state, so that the user can attach the body attachment unit 20 to the skin by performing only the operation of operating the applicator 10 without performing a separate additional operation for attaching the body attachment unit 20 to the skin. In particular, since a separate wireless communication chip is provided in the body attachment unit 20, so that a separate transmitter is not required, use can be more conveniently performed.

[0052] In the applicator 10, a separate protective cap 200 can be detachably combined in a manner in which the body attachment unit 20 is shielded from being exposed to the outside in a state in which the body attachment unit 20 is inserted into the inside of the applicator 10, and can be configured such that the user operates the applicator 10 to discharge the body attachment unit 20 to the outside toward a side from which the protective cap 200 is removed to be attached to the body after the protective cap 200 is separated.

[0053] At this time, an adhesive tape 560 is attached to the body contact surface of the body attachment unit 20 in a manner in which the body attachment unit 20 can be attached 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, and the release paper of the adhesive tape 560 can be formed to be separated and removed from the adhesive tape 560 in the process of separating the protective cap 200 from the applicator 10.

[0054] The applicator 10 can be formed to combine and fix the body attachment unit 20 in a state in which the body attachment unit 20 is inserted into the inside, and to release the combined and fixed state with the body attachment unit 20 in a state in which the body attachment unit 20 is discharged and moved to the outside. Therefore, in a state in which the body attachment unit 20 is inserted and assembled into the inside of the applicator 10, the body attachment unit 20 is maintained in a fixed state, and in the case in which the applicator 10 is operated to discharge the body attachment unit 20 to the outside and attach it to the skin, the combined and fixed state of the applicator 10 and the body attachment unit 20 is released, and thus if 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 in a state of being attached to the skin.

[0055] The body attachment unit 20 is formed to provide a sensor part 520 in the inside of a separate housing 510, and one end of the sensor part 520 can protrude to the outside from the bottom surface of the housing 510 to be inserted and attached to the body. The sensor part 520 is formed of a sensor probe part 521 (refer to Figure 5 ) inserted into the body and a sensor main part 522 (refer to Figure 5The sensor component 520 is composed of a sensor probe and a sensor body, which are curved and form one end and the other end of the sensor component 520, respectively.

[0056] At this time, the individual guide pin 550 can be detachably attached to the housing 510 to facilitate the insertion of the sensor component 520 into the body. The guide pin 550 is configured to surround one end of the sensor component 520 and is inserted into the body together with the sensor component 520 to ensure that one end of the sensor component 520 is stably inserted into the body.

[0057] like Figure 2 As shown, the guide needle 550 is detachably mounted on the housing 510 along the direction of vertical penetration through the housing 510 of the body application unit 20, and is formed to surround the outside of the sensor component 520, with a needle tip 551 formed at its upper end. This guide needle 550 is inserted into the body before the sensor component 520 when the body application unit 20 moves in the external discharge direction via the applicator 10, and guides the sensor component 520 to be stably inserted into the skin. The guide needle 550 is configured to engage with the needle removal mechanism (not shown) of the applicator 10 via the needle tip 551, and is withdrawn and removed from the body by the needle removal mechanism of the applicator 10 after the body application unit 20 is inserted and applied to the body by the operation of the applicator 10.

[0058] Figure 4 This is a diagram illustrating the body insertion process of the body attachment unit of the applicator according to an embodiment of the present invention. Figure 5 and Figure 6 This is a diagram illustrating the connection structure between the body attachment unit and the protective cap according to an embodiment of the present invention.

[0059] As described above, an embodiment of the present invention, the applicator 10, is a device that operates by inserting and attaching the body attachment unit 20 to the body through user operation. It may include a main shell 100 with one side open, a plunger body 300 that moves inside the main shell 100 in a direction toward the open side and outward discharge, and a plunger elastic spring S1 that applies an elastic force to the plunger body 300 in a way that moves the plunger body 300 in the outward discharge direction. It may be configured such that the body attachment unit 20 is attached to the plunger body 300 and moves together with the plunger body 300 in the outward discharge direction.

[0060] An operation part such as a push button (not shown) operable by a user is provided outside the main case 100, the plunger body 300 is fixedly coupled to the first position inside the main case 100, and is released from the fixed coupling to the first position by the operation of the operation part, and is linearly moved to the second position which is the external discharge direction by the elastic force of the plunger elastic spring S1. The body attachment unit 20 is coupled to one end of the plunger body 300 to be linearly moved together with the plunger body 300 in the external discharge direction, and is inserted into the skin E of the body to be attached thereto.

[0061] As described above, the body attachment unit 20 includes a housing 510, a sensor part 520 including a sensor body part 522 and a sensor probe part 521, and a guide needle 550 provided to be able to surround the sensor probe part 521 from the outside and to be detachably coupled to the housing 510. A battery 535 is installed inside the housing 510 to supply power to the PCB substrate 530 and the PCB substrate 530. A wireless communication chip (not shown) for communication with an external terminal is installed on the PCB substrate 530, and the sensor part 520 is electrically connected to the PCB substrate 530 through an electrical contact 531.

[0062] The sensor probe part 521 is protrusively provided from the bottom surface of the housing 510 to the outside in such a manner that the sensor probe part 521 of the sensor part 520 is inserted into the skin E of the body when the body attachment unit 20 is discharged to the outside, and the guide needle 550 surrounds the sensor probe part 521 from the outside and is inserted into the skin E of the body together with the sensor probe part 521.

[0063] The guide needle 550 is withdrawn from the skin E and removed after being inserted into the skin E of the body, and a needle withdrawal mechanism N is provided in the applicator 10 to withdraw and remove the guide needle 550 from the skin E of the body in a state in which the guide needle 550 is inserted into the skin E of the body.

[0064] The needle withdrawal mechanism N can include a needle withdrawal body 400 engaged to be coupled to the plunger body 300 to be linearly moved together with the plunger body 300 in the external discharge direction, and to be coupled to a needle 551 formed at an upper end of the guide needle 550, and a needle withdrawal elastic spring S2 applying an elastic force to the needle withdrawal body 400 in the opposite direction of the external discharge direction. A hook engagement part 350 capable of restricting the elastic movement of the needle withdrawal body 400 is formed in the plunger body 300, and an elastic hook 410 engaged to be coupled to the hook engagement part 350 is formed at an upper portion of the needle withdrawal body 400. The elastic hook 410 is engaged with the hook engagement part 350 so that the needle withdrawal body 400 is integrally moved together with the plunger body 300 in the external discharge direction, and when a predetermined distance is moved, the engaged state of the elastic hook 410 and the hook engagement part 350 is released by a separate locking release mechanism not shown, in which state the needle withdrawal body 400 is upwardly moved in the opposite direction of the external discharge direction by the needle withdrawal elastic spring S2.

[0065] That is, such as Figure 4 As shown in (a), when the applicator 10 is placed on the skin with the protective cap 200 removed from the applicator 10, and the pressure button 110 is pressed, as... Figure 4 As shown in (b), the body attachment unit 20 is ejected to the outside along with the plunger body 300, allowing the end portion of the sensor component 520 to be inserted into the skin. Meanwhile, as... Figure 4 As shown in (c), the guide needle 50 is withdrawn from the skin and removed by the needle withdrawal mechanism N. Subsequently, when the patch 10 is detached from the skin, only the body attachment unit 20 remains attached to the skin, and blood glucose is periodically measured in this state.

[0066] In a continuous blood glucose measurement device according to an embodiment of the present invention, as described above, with the body attachment unit 20 disposed inside the patch 10 and the protective cap 200 attached, after removing the protective cap 200, the body attachment unit 20 can be ejected to the outside and inserted and attached to the body by pressing the button of the patch 10.

[0067] At this time, the applicator 10 can be configured to prevent the body attachment unit 20 from being discharged to the outside when the protective cap 200 is attached, specifically, by pressing the button. For example, the protective cap 200 may have a separate locking protrusion that restricts the pressing movement of the button when attached to the applicator 10.

[0068] On the other hand, a continuous glucose measurement device according to an embodiment of the present invention can be configured to start operation by supplying power to the battery 535 through user operation when the body attachment unit 20 is disposed inside the patch 10. That is, it can be configured to supply power to the body attachment unit 20 through user operation before the body attachment unit 20 is discharged from the patch 10 to the outside.

[0069] For this purpose, a power supply switch mechanism PS may be provided that operates in conjunction with the separation and removal action of the protective cap 200 to supply power to the body attachment unit 20 to the battery 535.

[0070] As previously described, the body attachment unit 20 includes a housing 510, a PCB substrate 530, and a sensor component 520. A battery 535 capable of being electrically connected to the PCB substrate 530 is installed inside the housing 510. At this time, the power supply switch mechanism PS operates in such a way that it supplies power from the battery 535 to the PCB substrate 530 as the protective cap 200 is separated and removed.

[0071] like Figure 5 and Figure 6As shown, a working protrusion 205 can be formed on one side of the protective cap 200, and an insertion guide 513 can be formed on the housing 510 of the body attachment unit 20 in a manner to guide insertion of the working protrusion 205, and can be configured such that, when the electrical appliance element or the like that works by such a mechanism is inserted into the body attachment unit 20, the working protrusion 205 is pressed against the insertion guide 513, and the working protrusion 205 and the insertion guide 513 are brought into contact with each other, and the working protrusion 205 and the insertion guide 513 are brought into contact with each other. Figure 6 As shown, when the protective cap 200 is separated and removed, the power supply switch mechanism PS works to supply power to the PCB substrate 530.

[0072] Thus, in a state in which the body attachment unit 20 is present inside the applicator 10, power is supplied to the body attachment unit 20 by the user's operation such as separation and removal of the protective cap 200 to start working, thereby making the start time point of the working of the body attachment unit 20 be formed by the user's operation before being attached to the body, and thus enabling the body attachment unit 20 to start working at an appropriate time point. In particular, even without performing a separate additional work for starting the working of the body attachment unit 20, the body attachment unit 20 can be started to work only by removing the protective cap 200 to further improve the convenience of use.

[0073] The power supply switch mechanism PS of the first embodiment of the present application will be described in more detail below.

[0074] Figure 7 is a conceptual view conceptually outputting the structure of the power supply switch mechanism of the first embodiment of the present application, Figure 8 is a view schematically showing the structure of the power supply switch mechanism shown in Figure 7

[0075] The power supply switch mechanism PS1 of the first embodiment of the present application includes a substrate contact point 501 formed on the PCB substrate 530, a battery contact point 502 connected to the battery 535, and a switch terminal 503 movably installed inside the housing 510 in a manner to be in contact with the substrate contact point 501 and the battery contact point 502 at the same time, and the switch terminal 503 is configured to move in a manner to be in contact with the substrate contact point 501 and the battery contact point 502 at the same time in conjunction with the separation and removal operation of the protective cap 200 to be electrically connected to each other.

[0076] At this time, an elastic member 5031 that applies an elastic force to the switch terminal 503 in a direction to be in contact with the substrate contact point 501 and the battery contact point 502 at the same time can be provided inside the housing 510, and in addition, the working protrusion 205 that presses the switch terminal 503 in a manner to be spaced apart from the substrate contact point 501 and the battery contact point 502 in a state in which the protective cap 200 is coupled to the applicator 10 can be protrusively formed on one side of the protective cap 200.

[0077] As shown in Figure 7 ​(a) of FIG. 1, and Figure 8 As shown in (a) of FIG. 2, in a state where the protective cap 200 is combined to the applicator 10, the working protrusion 205 presses the switch terminal 503 so that the switch terminal 503 is located at a position spaced apart from the substrate contact 501 and the battery contact 502, and thus the substrate contact 501 and the battery contact 502 are not connected to each other, and thus the battery power is not supplied to the PCB substrate 530.

[0078] After that, when the user wants to insert the body attachment unit 20 into attachment to the body, it is necessary to separate and remove the protective cap 200 from the applicator 10, and when the protective cap 200 is separated and removed as shown in (b) of FIG. 2, the working protrusion 205 releases the pressure on the switch terminal 503, and thus the switch terminal 503 is moved by the elastic force of the elastic member 5031 and simultaneously contacts the substrate contact 501 and the battery contact 502. Thus, the substrate contact 501 and the battery contact 502 are electrically connected to each other through the switch terminal 503 and supply the battery power to the PCB substrate 530, and the body attachment unit 20 starts to operate. Figure 7 Figure 8

[0079] At this time, an insertion guide 513 which protrudes to the inside direction in a manner to insert and guide the working protrusion 205 of the protective cap 200 can be formed on the bottom surface of the housing 510. In addition, a shielding film 514 of a flexible material can be installed on the protruding end portion of the insertion guide 513 in a manner to shield the inside space of the housing 510 from the outside. The shielding film 514 is used to perform a waterproof function for the inside space of the housing 510, and can be formed of a flexible material which can be deformed by the pressure of the working protrusion 205.

[0080] Figure 9 is a conceptual view conceptually showing a structure of a power supply switch mechanism of a second embodiment of the present application, Figure 10 is a view schematically showing a structure of a power supply switch mechanism for implementing Figure 9 as shown in FIG. 1.

[0081] ​​The power supply switch mechanism PS2 of the second embodiment of the present invention may include: a switch element 504 that electrically connects or disconnects the battery 535 and the PCB substrate 530 according to an electrical signal input to the enable terminal 5041; a switch contact 505, one end of which is grounded and the other end of which is connected to the enable terminal 5041; and a connection terminal 506 formed on one side of the protective cap 200 to electrically connect or disconnect one end of the switch contact 505 from the other end depending on whether the protective cap 200 is removed. In this configuration, when the connection terminal 506 electrically connects one end of the switch contact 505 from 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 via the power of the battery 535. Furthermore, the switch contact 505 is formed within the internal space of the housing 510, and the connection terminal 506 may be formed at the end of the working protrusion 205 of the protective cap 200.

[0082] like Figure 9 (a) and Figure 10 As shown in (a), with the protective cap 200 attached to the applicator 10, the connecting terminal 506 of the working protrusion 205 connects and contacts the switch contact 505, so that one end of the switch contact 505 is electrically connected to the other end; as Figure 9 (b) and Figure 10 As shown in (b), when the protective cap 200 is removed from the applicator 10, the connection terminal 506 of the working protrusion 205 is spaced apart from the switch contact 505, so that one end of the switch contact 505 is electrically disconnected from the other end.

[0083] When one end of switch contact 505 and the other end are electrically connected via connection terminal 506, a low electrical signal is input to enable terminal 5041 of switch element 504. In this case, switch element 504 operates in a manner that electrically disconnects battery 535 and PCB substrate 530. Therefore, power is not supplied to PCB substrate 530 from battery 535.

[0084] When the connection terminal 506 is spaced apart from one end and the other end of the switch contact 505, the electrical connection between one end and the other end of the switch contact 505 is blocked, 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 in a manner that electrically connects the battery 535 and the PCB substrate 530, and the power of the battery 535 is supplied to the PCB substrate 530, causing the body attachment unit 20 to start working.

[0085] The operation of the switch contact 505 and the switch element 504 is exemplary, and various modes other than this can be employed. As the switch element 504, a TR (transistor), a FET (field effect transistor), an analog switch IC, or the like can be employed.

Therefore, the disclosed embodiments of the present application are not intended to limit the technical idea of the present application, but to explain the technical idea of the present application, and the scope of the technical idea of the present application is not limited by such embodiments.
