The present invention relates to a sensor applicator assembly for a continuous glucose meter, which enables accurate and safe use and is also convenient for maintenance.

Diabetes is a chronic disease that occurs frequently in modern people, and in Korea, more than 2 million people, or 5% of the total population.

Diabetes has a huge amount of sugar in the blood due to the lack of or relative lack of insulin produced by the pancreas due to various causes, such as obesity, stress, poor diet, and congenital heredity. Loses and develops.

Blood usually contains a certain concentration of glucose, and tissue cells are getting energy from it.

However, when glucose is increased more than necessary, it is not properly stored in the liver, muscle, or fat cells, and accumulates in the blood, which causes diabetes patients to maintain a much higher blood sugar level than a normal person, and excessive blood sugar passes through the tissues directly into the urine. As it is released, the sugars that are absolutely necessary for each tissue of the body are insufficient, causing abnormalities in each tissue of the body.

Diabetes is characterized by almost no symptoms in the early stages, and when the disease progresses, it is characteristic of diabetes mellitus, followed by polyps, polyuria, weight loss, systemic boredom, itching of the skin, and long-lasting pain in the hands and feet. When the disease progresses further, complications develop into vision disorders, hypertension, kidney disease, stroke, periodontal disease, muscle spasms and neuralgia, gangrene, and the like.

In order to diagnose this diabetes and manage it to prevent the development of complications, systematic blood glucose measurement and treatment should be combined.

For diabetics and people who have not advanced to diabetes but have detected more than normal sugar in their blood, many medical device manufacturers offer a variety of blood glucose meters to measure blood glucose at home.

The blood glucose meter includes a method in which a user collects blood from a fingertip and performs blood glucose measurement in a unit of time, and a method in which blood glucose measurement is continuously attached to a user's abdomen and arm.

In people with diabetes, they usually go between high and low blood sugar levels, and emergencies come from low blood sugar, and they may die if they are unconscious or have a low blood sugar for a long time without sugar. Therefore, the immediate detection of hypoglycemic state is very important for diabetics, but there is a limit to accurately grasp it with a blood glucose meter which measures blood glucose intermittently.

Recently, a continuous glucose monitoring system (CGMS), which is inserted into the human body and measures blood glucose levels at intervals of minutes, has been developed to overcome these limitations, thereby facilitating the management of diabetes patients and coping with emergencies. Can be done.

In addition, the blood glucose meter is a blood glucose measurement by diagnosing a blood glucose measurement by diagnosing the blood sugar of a patient with a needle to check his blood sugar, causing pain and rejection in the blood collection process. In order to minimize such pain and rejection, a research and development of a continuous blood glucose measurement system that continuously measures blood glucose after inserting a needle-like sensor into a region of the lower pain and abdomen has been conducted. The research and development of the Non-Invasive Glucose Monitoring System, which measures blood glucose without collecting blood, has also been actively conducted.

The non-invasive blood glucose measurement system has been studied for various methods such as optical method, electrical method, and exhalation measurement to measure blood glucose without collecting blood for the past 40 years. Cygnus, Redwoo City, Ca, USA, developed and released a wristwatch-type Glucowatch G2 Biographer using reverse ion osmosis, but had skin irritation and blackness, device stopped during sweating, and high blood sugar. In 2007, the company was discontinued due to problems with low blood sugar. To date, many bloodless blood glucose measurement techniques have emerged and are reported, but they are not used in practice due to their poor accuracy.

The continuous blood glucose meter includes a sensor module attached to the skin of the body and extracting body fluid to measure blood glucose, a transmitter for transmitting the blood glucose level measured by the sensor module to the terminal, a terminal for outputting the received blood glucose level, and the like. It is composed. The sensor module is provided with a sensor probe or the like inserted into the subcutaneous fat and formed in the shape of a needle to extract the cell interstitial fluid, and a separate applicator is used to attach the sensor module to the body.

Such continuous blood glucose meters are manufactured in various forms for each manufacturer, and various methods of use are also made. However, most continuous blood glucose meters are manufactured and distributed by attaching the disposable sensor module to the body through the applicator, and the user has to perform several steps to operate the applicator for the body attachment of the disposable sensor module. After attaching the sensor module to the body, a number of follow-up procedures must be performed, including the need to pull out the needle directly.

For example, the package of the disposable sensor module should be peeled off and inserted into the applicator correctly. The sensor module is inserted into the skin by operating the applicator while the sensor module is inserted into the applicator. Tasks such as pulling the sensor module needle directly out of the skin should be performed.

Therefore, there is a problem that the task for measuring blood glucose using a continuous blood glucose meter is very cumbersome and inconvenient. In addition, the transmitter for transmitting the information of the sensor module to the terminal, even though it is quite expensive, is used for one-time use with the sensor module, there is a problem that is very inefficient in terms of economic and environmental aspects.

The sensor applicator assembly 1 for a continuous glucose meter according to an embodiment of the present invention is an assembly in which the sensor module 20 and the applicator 10 are assembled into a unit product, and a user is added when the continuous glucose meter is used. It is a very simple structure with minimal work.

The sensor module 20 is formed to be attached to the body to extract the body fluid and periodically measure the blood sugar, and a separate transmitter 30 to transmit the blood sugar measurement result to an external device such as a terminal (not shown) It is formed so that it can be connected.

The applicator 10 is formed such that the sensor module 20 is fixedly coupled therein, and operates to externally discharge the sensor module 20 by a user's manipulation.

In this case, the sensor module 20 is assembled and manufactured in a state of being inserted into the applicator 10, and is configured to be attached to a body by moving in an external discharge direction according to the operation of the applicator 10 by a user's operation.

That is, the sensor applicator assembly 1 according to an embodiment of the present invention is a skin of the sensor module 20 only by the operation of the applicator 10 with the sensor module 20 inserted into the applicator 10 in the manufacturing step. Since it is assembled and manufactured to be attached to the user and is supplied to the user in this state, the user does not need any additional work for attaching the sensor module 20 to the skin, and the user simply skins the sensor module 20 by simply operating the applicator 10. Can be attached to After attaching the sensor module 20 to the skin as described above, by combining a separate transmitter 30 to the sensor module 20, the blood glucose measurement results can be periodically output to the terminal of the continuous blood glucose meter.

When the sensor module 20 is attached to the body and used for about one week, the end of life is used, and then a new sensor module 20 must be attached to the body again. At this time, the sensor module 20 and the applicator 10 Is manufactured and used for one time, the transmitter 30 is still used as a separate product. That is, since the sensor module 20 is supplied to the applicator 10 in an attachable state to the body, the user does not need to insert the sensor module 20 into the applicator 10 or perform additional work. The user simply attaches the sensor module 20 to the body by simply operating the applicator 10, and the sensor module 20 and the applicator 10 used in this way cannot be reused after use is completed, and again The sensor applicator assembly 1 is used to newly attach the sensor module 20 to the body. In this case, the transmitter 30 may be configured to be continuously reused as a separate product instead of a disposable product.

The conventional continuous blood glucose meter removes a separately packaged sensor module and accurately inserts the package into the applicator. After inserting, the sensor module is attached to the skin by operating the applicator. The operation of inserting the sensor module accurately into the applicator is performed. In addition to the cumbersome and difficult, there was a problem of deteriorating the blood sugar measurement accuracy, such as the contamination of the sensor module during the operation of young children or elderly people.

In an embodiment of the present invention, by manufacturing and distributing the sensor module 20 in the state of being inserted into the applicator 10 in the manufacturing step, the process of the user peeling off the sensor module 20 and inserted into the applicator 10 is omitted. In addition, since the sensor module 20 can be attached to the skin by simply operating the applicator 10, usability is remarkably improved, and in particular, contamination of the sensor module 20 can be prevented, and thus blood glucose measurement accuracy is achieved. Can improve.

Since the sensor module 20 is manufactured in such a state that the sensor module 20 is inserted into the applicator 10, the sensor module 20 and the applicator 10 may be preferably used for one-time reuse. For this non-reusable structure, the applicator 10 according to an embodiment of the present invention is formed so that reinsertion of the sensor module 20 is impossible after the sensor module 20 inserted therein is operated once to be discharged outside. do.

That is, the applicator 10 is formed in an open form on one side and the sensor module 20 is configured to be discharged through the open one side of the applicator 10, through the first one operation of the applicator 10 When the sensor module 20 is externally discharged, the sensor module 20 may not be inserted by the user so that another sensor module 20 may not be inserted into the applicator 10 and used.

Meanwhile, a separate protective cap 200 may be detachably coupled to the applicator 10 so that the external exposure is blocked while the sensor module 20 is inserted into the applicator 10, and the user may have a protective cap 200. It may be configured to attach the sensor module 20 to the body by operating the applicator 10 only after removing the).

In this case, the adhesive tape 560 is attached to the body contact surface of the sensor module 20 so that the sensor module 20 may be attached to the body, and the release paper for protecting the adhesive tape 560 on the body contact surface of the adhesive tape 560. 561 is attached, the release paper 561 of the adhesive tape 560 may 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.

For example, the release paper 561 may be configured such that one side is bonded to the protective cap 200, and thus, when the user separates the protective cap 200 from the applicator 10, together with the protective cap 200. It may be separated from the adhesive tape 560. Accordingly, when the user detaches the protective cap 200, the release paper 561 of the adhesive tape 560 is separated and removed, so that the sensor module 20 can be attached to the body by operating the applicator 10 in this state. have.

In addition, the applicator 10 is coupled and fixed to the sensor module 20 in a state in which the sensor module 20 is inserted therein and fixedly coupled to the sensor module 20, and the sensor module 20 is discharged outside. It can be formed to release. Therefore, in the state in which the sensor module 20 is inserted into the applicator 10 and assembled, the sensor module 20 is maintained in a fixed state, and the applicator 10 is operated to externally discharge the sensor module 20 to the skin. In the case of attaching to the applicator 10 and the sensor module 20, the fixed state of the applicator 10 is released, and thus, when the applicator 10 is removed in this state, the applicator 10 is separated from the sensor module 20. It remains attached.

Next, let's take a closer look at each detailed configuration.

First, the protective cap 200 is detachably coupled to an open surface of the applicator 10 to block external exposure of the sensor module 20 inserted into the applicator 10. As shown in FIG. 7, the locking member 210 is formed to prevent the protection cap 200 from being separated from the state in which the protective cap 200 is coupled to the applicator 10, and the locking member 210 is locked and locked by a user's operation. It is formed to be released.

The locking member 210 is configured to include a locking lever 211 rotatably coupled to one side of the protective cap 200, and a locking locking protrusion 213 formed at one end of the locking lever 211. The lever 211 may have an elastic hinge shaft 212 formed at an intermediate point, and both ends thereof may be elastically rotated about the elastic hinge shaft 212. In addition, a locking locking groove 1011 may be formed on the outer circumferential surface of the applicator 10 so that the locking locking protrusion 213 may be inserted into and engaged with the configuration of the locking member 210.

In this case, the locking lever 211 may be configured to be elastically supported by the elastic hinge shaft 212 in a direction in which the locking locking protrusion 213 is inserted into and engaged with the locking locking groove 1011.

According to this configuration, the protective cap 200 remains coupled to the applicator 10 unless the user presses the lower end of the locking lever 211 as shown in FIG. 8A, and presses the locking lever 211. Thus, as shown in FIG. 8B, the locking cap protrusion 213 is disengaged from the locking locking groove 1011, so that the protective cap 200 may be separated and removed from the applicator 10.

The protective cap 200 wraps around the outer circumferential surface of the applicator 10 and forms an outer cover part 201 formed to be coupled to one end of the applicator 10 and an applicator from one end of the outer cover part 201. An extension portion 202 extending in the inner center direction of the 10, and an inner support portion 203 extending upward from the extension portion 202 and supporting a body contact surface of the sensor module 20 inserted into the applicator 10.

In the process of separating from the protective cap 200 together with the adhesive tape 560 is formed to be removed.

In this case, the release paper 561 may be attached to the upper surface of the inner support part 203 of the protective cap 200, and may be attached to the inner support part 203 of the protective cap 200 through a separate adhesive member 562. . That is, as shown in FIG. 9A, a separate adhesive member 562 is attached to one side of the lower surface of the release paper 561, and the adhesive member 562 may have an upper surface of the inner support part 203 of the protective cap 200 and a release paper ( The lower surface is attached to the upper surface of the inner support portion 203 positioned between the 561. The adhesive force of the adhesive member 562 is greater than the adhesive force between the release paper 561 and the adhesive tape 560. Accordingly, when the protective cap 200 is separated from the applicator 10, the release paper 561 bonded to the inner support 203 of the protective cap 200 through the adhesive member 562 is separated together and the adhesive tape 560 is separated. Is separated and removed from.

At this time, two release lines (not shown) having a separation distance of the same size as the width of the adhesive member 562 may be formed in some sections in the release paper 561 in parallel to each other, as shown in FIG. 9B. In the process of separating the protective cap 200 as described above, the release paper 561 together with the adhesive member 562 is first separated and separated from the adhesive tape 560 along the incision line, and then the separation process of the protective cap 200 continues. As it proceeds, that is, as the protective cap 200 continues to move downward relative to the direction shown in FIG. 9B, the release paper 561 in portions other than the incision line is pulled out and separated from the adhesive tape 560. Through the separation and removal process of the release paper, the separation removal work of the release paper 561 may be more smoothly and stably performed.

On the other hand, the locking lever 211 of the above-described protective cap 200 may be formed on one side of the central portion of the outer cover portion 201 of the protective cap 200. For example, the locking lever 211 is formed in a form in which a portion of the outer cover portion 201 is cut off, and an elastic hinge shaft 212 is formed on one side of the incision line so as to be connected to the outer cover portion 201.

It may be configured to include a return preventing hook 104 is elastically supported in the pressing direction.

As shown in FIG. 20, the anti-return hook 104 protrudes from an elastic body 1041 made of an elastic material and extends from the inner upper surface of the main case 100 to the lower side thereof, and a lower end of one side of the elastic body 1041. It may be configured to include a hook portion 1042 to be formed. The elastic body 1041 may be integrally formed on the bottom surface of the cover case 103 coupled to the upper end of the outer case 101 of the main case 100. In addition, the elastic body 1041 may be formed to be elastically deflected in a form inclined toward the center toward the lower end so that the hook portion 1042 to elastically press the outer surface of the plunger body 300.

The hook portion 1042 elastically pressurizes the outer surface of the plunger body 300 by the elastic force of the elastic body 1041 in a state where the plunger body 300 is located in the first position, and the plunger body 300 is in the second position. In the state located in the elastic body 1041 is elastically moved to the center side by the elastic force is formed to be engaged with the upper end of the plunger body (300).

That is, the stopper portion 1043 is formed, thereby limiting excessive elastic movement of the elastic body 1041 to accurately induce the engagement state of the hook portion 1042 and the plunger body 300. In addition, even when the elastic movement force of the elastic body 1041 is largely formed, since the movement is constrained in place by the stopper portion 1043, the elastic movement speed of the elastic body 1041 can be increased, thereby enabling a faster movement. Therefore, the return prevention function can be performed more stably.

On the other hand, the applicator 10 is configured to withdraw the removal of the needle portion 550 of the sensor module 20 from the body at the same time the sensor module 20 completes the external discharge movement from the first position to the second position. The applicator 10 may be provided with a needle extracting means (N) for the plunger body 300 is completed from the first position to the second position and at the same time move the needle portion 550 up and out of the body.

The needle dispensing means N is engaged with the needle head 551 of the needle portion 550 and engaged with the plunger body 300 so as to be engaged in the first position along the inner case 102 with the plunger body 300. The needle extracting body 400 which moves linearly to the second position and the needle extracting elastic spring S2 which applies the elastic force to the needle extracting body 400 in the direction in which the needle extracting body 400 moves upward toward the first position are further added. It may include.

The needle extracting body 400 is engaged with the plunger body 300. For this, the needle extracting body 400 is provided with a separate elastic hook 410 that is elastically deformable, and the elastic hook 410 has the plunger body 300. It is elastically biased in the direction that is engaged with the hook engaging portion 340 of the). Therefore, when the plunger body 300 moves linearly from the first position to the second position according to the operation of the pressing button 110, the needle extracting body 400 also moves linearly to the second position together with the plunger body 300. .

In this case, the inner hook 102 has an elastic hook 410 such that the elastic hook 410 is disengaged from the hook engaging portion 340 of the plunger body 300 as the needle extracting body 400 moves to the second position. Needle withdrawal pressing portion 130 for pressing in the inward direction is formed.

According to this structure, when the pressing button 110 is pressed, the needle extracting body 400 moves linearly from the first position to the second position together with the plunger body 300, and at the same time, the elasticity of the needle extracting body 400 is increased. Since the hook 410 is pressed by the needle extracting pressure unit 130 of the inner case 102 to release the engagement with the hook engaging portion 340, the needle extracting body 400 of the needle extracting elastic spring S2 is removed. The elastic force causes the upward movement toward the first position.

At this time, since the needle withdrawal body 400 is coupled with the needle head 551 of the needle portion 550 through one end of the needle head coupling portion 420, the needle withdrawal body 400 moves in an upward return direction. The portion 550 moves together and is removed from the body. The needle head coupling part 420 is formed at the lower end of the needle extracting body 400 in a form of being engaged with the coupling groove 552 formed in the needle head 551.

The needle extracting body 400 may move upward to the upper end of the inner surface of the main case 100 by the elastic force of the needle extracting elastic spring S2 instead of moving upward only to the first position. In this case, the needle withdrawal body 400 is moved by the elastic force and hit the upper end of the inner surface of the main case 100, the impact may occur, so that the shock absorbing on the upper inner surface of the main case 100 to mitigate such impact Member 1031 may be coupled. The shock member 1031 can minimize the impact noise to prevent the user from causing anxiety of the operation of the device. The shock absorbing member 1031 may be coupled to the cover case 103 constituting the upper end of the main case 100.

On the other hand, as the plunger body 300 moves to the second position by the elastic force of the plunger elastic spring S1, the sensor probe 521 and the needle part 550 of the sensor module 20 are inserted into the body. An insertion resistance may be generated during the body insertion process of 550, and the needle part 550 may be finely retracted in a direction opposite to the body insertion direction by reaction force. In this case, since the sensor probe 521 may not be inserted into the body at a normal depth, the retraction of the needle part 550 is preferably prevented. To this end, the needle support block 430 supporting the upper end of the needle part 550 may be coupled to the needle extracting body 400 such that the needle part 550 does not relatively move upward with respect to the needle extracting body 400. have.

Of course, at this time, the sensor module 20 is adhered to the surface of the body (E) by the adhesive tape 560. As such, when the plunger body 300 moves in the external discharge direction, as shown in FIG. 22B, the plunger body 300 is engaged by the return preventing hook 104 of the outer case 101 and cannot move upward again. . Therefore, once used applicator 10 is not reused again.

When the plunger body 300 moves downward, the sensor fixing hook 330 of the sensor accommodating part 301 is released by the concave surface 142 of the hook guide part 140, as shown in FIG. 22A. The engagement state with the module 20 is released. In addition, the elastic hook 410 of the needle extracting body 400 is pressed inward by the needle extracting pressing unit 130 of the inner case 102 to release the engagement with the plunger body 300.

Therefore, when the plunger body 300 moves downward, at the same time as shown in FIG. 23, the needle extracting body 400 is moved upward and upward by the needle extracting elastic spring S2. At this time, since the needle part 550 moves upward together with the needle extracting body 400, the needle part 550 is removed from the body E.

In this state, since the engagement state between the sensor fixing hook 330 and the sensor module 20 is released as described above, as shown in FIG. 24, the applicator 10 may be upwardly separated and removed. When the applicator 10 is removed and removed as described above, only the sensor module 20 is attached to the body E. Thereafter, when the separate transmitter 30 is coupled to the sensor module 20 to be connected to the connection terminal 513, the blood glucose measurement result by the sensor module 20 is transmitted to the user terminal by the transmitter 30.
