Description

Blood Glucose Measurement System

The present invention relates to a blood glucose measurement system, and in particular, does not need to separately store, manage and carry a blood needle, a test strip, and a blood glucose meter separately, and allows blood to penetrate the skin with a single operation to collect blood and measure blood glucose. It relates to a measuring system.

As is well known, the World Diabetes Federation warns that more than 260 million people with diabetes worldwide will be over the next 20 years, and the number of diabetics is increasing by 8.6% every year. This is urgent.

It is very important to manage the blood sugar to check whether there is diabetes, and to manage and measure such blood sugar, conventionally, acupuncture needles, blood collectors, blood glucose meters, strips, alcohol balls, etc. can be carried, equipped, and managed at any place. It is inevitable to take the hassle to do so.

After preparing these various instruments, in the case of self-use repeated use, wipe the blood sampling needle with alcohol swab, turn on the blood glucose meter, insert the strip, and then attach the metal needle-like lancet to the lancing device. This blood collection system cuts or penetrates the surface of the skin to allow more blood to flow out than necessary for blood glucose measurement, accompanied by wounds and pain. It is absorbed by the capillary phenomenon and converted into a predetermined signal to display blood sugar in the blood glucose meter.

If any one of these series of tasks is delayed or if the blood penetrates shallowly and the blood volume is insufficient, the skin surface must be incision with the blood needle again, which is a very painful routine for diabetics. Even when going out, there was a problem that it was very inconvenient to carry out the complicated process as described above by carrying out the above-mentioned blood needle, blood collector, blood glucose meter, and strips, alcoholic cotton 2 or 4 times a day.

In addition, the above-described process using a needle-shaped needle needle in the present age where children are also causing diabetes due to excessive TV watching and unbalanced eating habits is causing greater fear and pain in children.

In an effort to alleviate this pain, U.S. Patent Application Publication No. 2005/0240119 (name of the invention; a blood glucose meter having a focused blood needle device and a test strip container for one-handed handling and a method of using the blood glucose meter having integral lancet) device and test strip storage vial for single handed use and methods for using same)) disclosed a blood glucose measurement device in which a blood collection device and a test strip storage container are integrated to be used with one hand.

However, it has a cylindrical structure as shown in FIG. 1 to provide a test strip storage space therein, and an insertion part 45 to which a test strip can be inserted, and a blood needle device 30 for elevating and bleeding separately. ), The cylinder depth adjusting device 32, the removable cover 47, the trigger button 50 and the internal drive structure and the blood glucose meter 80 should be provided so that its diameter or length is unfit for pocket use. Not only is it too large to be inconvenient to carry,

In order to prevent blood from being pierced by blood needles, the test strips must be buried in the prepared strips, and in many cases, blood pressure must be squeezed.

In addition, the test strip is removed from the storage container 75 and inserted into the test strip port 20 through the insertion part 45, and then operated by operating the operation button 84 of the blood glucose meter 80, and then the finger To the bottom of the cylindrical depth adjusting device 32, press the trigger button 50 so that the blood needle penetrates the fingertips so that the blood flows out, and then touches one end of the test strip. It is still inconvenient because it has to perform a cumbersome process to remove the strip and blood immersion.

A lifting tube accommodation space 261 having a lifting tube 268 for coupling and removing the composite molding 100 is positioned at the center of the receptor 260 extending from one side thereof.

In addition, the present invention can be applied to select any one of the known lifting means for the lifting of the blood needle 110, the known lifting means has a trigger button 262 installed on one side of the receptor 260, When the trigger button 262 is pushed down, the blood needle 110 descends momentarily as shown in FIG. 4B and then lifts back to its original position as shown in FIG. 4A.

In addition, in the present invention, as shown in Figure 5 allows the detachable cap 270 to be detached to the tip of the receptor 260, as well as the position of the separation cap 270 by rotating the blood immersion 110 The height of the inlet to the haunting hole 271 in the center of the separation cap 270 was adjusted to allow the depth of penetration of the blood needle 271 to penetrate the finger.

The blood glucose measurement system according to the present invention will be able to measure blood glucose at any time and any place simply by carrying only the blood glucose meter 200 and the composite molding 100 for blood glucose measurement.

To this end, the present invention, as shown in Figure 2 by opening the separation cap 270 is pushed to couple the terminal 130 of the new composite molding 100 to the connector 210, but the anti-slip piece 112 of the composite molding 100 ) Is coupled in the direction to be inserted into the misalignment prevention groove 267 of the elevating pipe 268, the terminal 130 of the compound molding 100 is coupled to the connector 210 in the correct direction, by doing so, Molding 100 is in close contact with the composite molding insertion hole 265, as shown in Figure 4 a), b) is elevated with the lifting pipe 268 and at the same time the test strip 120 is electrically connected to the connector ( 210 will be connected to the state.

Subsequently, the separation cap 270 is rotated to be coupled to the receptor 260, and as shown in FIG. 5, the separation cap 270 is rotated to adjust the skin penetration depth of the blood needle 110 formed integrally with the complex molding 100. Since the number of bites of the thread formed in the threaded portion 272 of the separation cap 270 and the receptor 260 is changed according to the degree to be made, when the trigger button 262 is operated, it emerges as a hole 271 of the separation cap 270. The length of the blood needle 110 is to be adjusted.

In this way, by operating the control button 240 to turn on the power,

When the end of the finger, which is the blood collection site, is applied to the hole 271 in the center of the separation cap 270, and then the trigger button 262 is pressed and released, as shown in FIG. 4 b), by the driving force of the trigger button 262. After the blood needle 110 protrudes into the hole 271, it is immersed again as shown in FIG. 4A, and thus the blood needle 110 penetrates the fingertips and damages a part of the capillaries that are aggregated. Since the blood is absorbed by the capillary 111 in the center of the blood needle 110, it is raised to the upper end of the capillary 111, and thus reaches one end of the test strip 120. Accordingly, an electro-chemical reaction occurs in the test strip 120, and since the signal is supplied to the circuit board 220 through the connector 210 connected to the terminal 130, the circuit board 220 responds to the signal. By calculating the corresponding blood sugar level is to display the blood sugar on the display 230 as shown in FIG. After checking blood glucose in this manner, the separation cap 270 is turned off, and the composite molding 100 is removed from the composite molding insertion hole 265 of the elevating pipe 268 and then discarded as shown in FIG. 2. Then, the separation cap 270 is turned to close for hygienic use for the next use, and then it is possible to repeat blood glucose measurement by the above-described process if necessary.

In this way, the blood glucose measurement system according to the present invention can simply measure the blood glucose at any time and any place simply by carrying only the blood glucose meter 200 and the composite molding 100 for blood glucose measurement.

In addition, a number of known lifting means that is one element constituting the present invention is widely used in the blood collection needle, in the present invention, the blood needle 110 and the test strip 120 is a composite of the integral body by the molding 121 Any known structure capable of elevating the molding 100 can be applied, and examples thereof are shown in FIGS. 6A), 6B), and 6C).

The structure as seen therein is elastically installed by the return spring 276, the trigger button 262 is fixed to the bottom projection 269 integrally, and the lower projection 269 of the trigger button 262 is coupled A guide plate 273 having a guide groove 274 for guiding the guide plate 274, a connecting shaft 275 connected to the elevating pipe 268 at the bottom thereof, and a top of the guide plate 273 connected to the composite molding. It is composed of a lifting pipe 268 provided with a compound molding insertion hole 265 into which (100) can be inserted. The elevating means is the elevating pipe 268 inside the container is upward by the return spring 276 inside the container 260 and the bullet spring 277 installed inside the separation cap 270 before operating the trigger button 262. As the blood pressure is pushed up, the blood needle 110 is positioned inside the receptor, and the trigger button 262 is moved upward to be in a state shown in FIG. 6A, which is the protrusion 269 of the guide plate 273. The guide groove 274 is positioned at the top. When the trigger button 262 is pushed downward in this state, the trigger button 262 is lowered by defeating the resistance of the return spring 276. In this state, the lowering of the blood needle 110 is not started. The downward projection 269 of the trigger button 262 is to be able to push down the guide plate 273 and the lifting pipe 268 connected thereto integrally, this state is shown in Figure 6b).

In this state, when the trigger button 262 is pushed further downward, the downward protrusion 269 of the trigger button 262 pushes the guide plate 273 and the elevating pipe 268 connected thereto integrally, and as a result, the blood needle 110 ) Is lowered to the state shown in FIG. 6C), and in this state, invasion of the fingertip and blood absorption by the capillary are performed as described above. 6C) is a condition that the elevating pipe 268 may raise the guide plate 273 regardless of the trigger button 262 by the ball spring 277, so that the trigger button 262 may be satisfied. The projection 269 is the guide plate 273 and the elevating pipe 268 at the same time as the elasticity of the bullet spring (277) in the stopped state, thereby increasing the composite molding insertion hole 265 of the elevating pipe (268) The composite molding 100 is inserted into the bar to be raised together, and the trigger button 262 is to overcome the elasticity of the return spring 276 and the elasticity of the descending length and the bullet spring 277 and ascends the descending length Will be done,

Since the guide plate 273 and the elevating pipe 268 are to rise only as much as the length of the falling down and overcome the elasticity of the ball spring 277, will eventually return to the state shown in Figure 6a before operation.

In addition, in the present invention, as shown in Figure 7 as another lifting means is provided with a trigger button 262 elastically installed by the return spring 276, and the elevating pipe 268 directly connected to the lower end of the trigger button 262 To ensure that

This also includes a composite molding insertion hole 265 that can insert the composite molding 100 in the elevating pipe 268 to operate the trigger button 262 and the composite molding 100 coupled to the elevating pipe 268 Blood needle 110 is to be linked.

As the lifting means of the simplified structure presses the trigger button 262, the blood needle 110 of the compound molding 100 invades through the skin and invades the capillaries at the fingertips so that blood is absorbed into the capillary 111. This means that it is possible to reach the test strip 120 and display the blood sugar in the above-described process. In particular, the lifting means of this structure is performed by the user by releasing the trigger button 262 to the force of the return spring 276. The invasive state of the blood needle 110 is maintained inside the finger until the lifting tube 268 and the blood needle 110 are separated from each other so that a sufficient amount of blood can be absorbed into the capillary tube 111 for a sufficient time. This is an advantage that allows more reliable blood glucose measurement.

Lifting means that can be used in this invention is shown as an example, whereby the technical features of the present invention is not limited.

In addition, in the present invention, as shown in FIG. 8, when the blood needle 110 invades the skin, blood absorption by the capillary 110 may be rapidly performed, as shown in FIG. 8. By forming an additional side hole 113 penetrating through the capillary tube 111 at the end, the area where the capillary tube 111 is exposed can be increased, so that blood can be absorbed more quickly by the capillary tube 111.

In addition, in the present invention, the measurement start and end of the blood glucose meter 200 is performed by operating the control button 240, but if necessary, the terminal 130 of the compound molding 100 is connected to the connector 210. At the moment, the microcontroller (not shown in the drawing) of the circuit board 220 recognizes this and presses the control button 240 so as to be in the same state as the power is "on". After removing the composite molding 100 from the connector 210 so as to be separated from the terminal 130 after use, the microcontroller (not shown in the drawing) of the circuit board 220 recognizes this. By pressing the control button 240 to be in the same state as the power "off" to stop the operation so that it is not necessary to operate the control button 240 separately, it is possible to improve the convenience of use.

In this way, the present invention can easily measure blood sugar anytime, anywhere by carrying only the compound molding 100 and the blood glucose meter 200 according to the present invention, and it is very useful because it does not have to carry, store and manage many accessories. It is convenient and its volume is small, which can further enhance the convenience of use.

In addition, according to the present invention, a series of handling procedures are very simple, and thus a quick blood sugar measurement is possible, and the measurement can be performed without squeezing blood out of the skin, thereby minimizing user stress associated with blood collection.

In the above, the present invention has been described with reference to a representative embodiment, but by combining various known elements according to the needs of the user, it can be carried out in various forms while maintaining the technical features of the present invention.
