Description

Portable glucose test strip for diabetics

[0001] The present invention relates to a test strip, and more specifically, to a portable glucose test strip that can be conveniently carried by a diabetic patient or the like to test for the presence or absence of glucose.

[0002] Diabetes is a disease in which glucose is excreted through urine. In normal individuals, blood sugar levels are controlled to prevent excessive sugar excretion in the urine. The hormone insulin plays a crucial role in this regulation process. However, if insulin is deficient or does not function properly, blood sugar levels rise, resulting in persistently high blood sugar levels, or diabetes symptoms.

[0003] Genetics and environment play a significant role in the development of diabetes. Diabetes is more likely to develop in individuals who inherited predisposing genes from their parents and are then exposed to a diabetes-prone environment. However, genetic abnormalities are currently known to be extremely rare. Most cases of diabetes are caused by environmental factors such as old age, obesity, stress, pregnancy, infections, medications (steroids, immunosuppressants, diuretics), and diet.

[0004] Unlike genetic factors, these environmental factors can be avoided to some extent through personal effort. However, recently, the increase in obesity due to excessive food intake and reduced exercise is being diagnosed as the cause of diabetes in many cases. While consuming a lot of sugar (carbohydrates) does not automatically cause diabetes, it is easy to gain weight, and obesity increases the risk of developing diabetes. Therefore, it is necessary to be careful about excessive sugar intake, and patients who already have diabetes require special attention as a rapid rise in blood sugar can cause lethargy or loss of consciousness, and even death.

[0005] For those who are averse to sugar intake and those who need to limit their sugar intake, such as diabetics, sugar-free drinks such as zero cola and zero sugar have been released and are gaining popularity. However, since these sugar-free drinks are visually indistinguishable from drinks with added sugar, a means of detecting whether or not sugar is included, such as a reagent reaction, is necessary. In particular, when ordering a drink in a place such as a cafe, there are times when another person's drink is brought by mistake or a drink with added sugar is served due to a clerk's mistake, which causes diabetic patients to feel anxious. To alleviate this anxiety, a portable means of detecting the presence of sugar is needed, and the device disclosed in 'Patent Document 1' is one example of such a device.

[0006] Fig. 1 is a perspective view of a portable glucose meter disclosed in Patent Document 1, and Fig. 2 is a configuration diagram thereof. Conventional portable glucose meters are composed of a container (1) for introducing urine, a blood strip insertion port (2) for inserting a blood strip, a blood current measurement processing module (3), a blood glucose value processing module (4), and a blood glucose value output module (5), and measure blood glucose contained in urine and blood. Although it is possible to determine whether a beverage contains sugar by introducing it into a device of this conventional portable glucose meter type, there is a problem that it is difficult for diabetic patients to easily use it due to the limitations of an electronic device, which makes it somewhat bulky and heavy, which reduces portability, and is expensive.

[0007] (Patent Document 1) KR 10-2019-0006763 A (January 21, 2019)

[0008] The present invention has been devised to solve the above problems, and the problem that the present invention seeks to solve is to provide a portable and inexpensive sugar detection means.

[0009] A portable glucose test strip for diabetic patients according to the present invention is characterized by comprising: a substrate portion having a vertically elongated rectangular shape; a reagent reaction portion formed on one side of the substrate portion by applying a reagent that changes color in response to sugar; and a palpable portion formed closer to the center of the substrate portion than the reagent reaction portion and absorbing or collecting a beverage.

[0010] The portable glucose test strip for diabetic patients according to the present invention is easy to carry and can be easily disposed of after use.

[0011] Also, since it does not use electronic devices, there is no need to worry about breakdowns, and the maintenance costs are significantly lower than those of conventional electronic devices.

[0016] Figure 5 is another embodiment of a portable glucose test strip for diabetic patients according to the present invention.

[0017] Figures 6 and 7 show other embodiments of the tactile part.

[0018] Hereinafter, a portable glucose test strip for diabetic patients according to the present invention will be described in detail with reference to the attached drawings.

[0019]

[0020] FIG. 3 is a perspective view of a portable glucose test strip for diabetic patients according to the present invention, and FIG. 4 is a diagram showing a state of use of a portable glucose test strip for diabetic patients according to the present invention. The portable glucose test strip for diabetic patients according to the present invention is composed of a substrate portion (10), a reagent reaction portion (20), and a palpation portion (30). After one end of the substrate portion (10) is immersed in a beverage to be measured, the beverage is allowed to pass through the reagent reaction portion (20) and the palpation portion (30), so that it is possible to determine whether the beverage contains sugar by a change in color of the reagent reaction portion (20) and a feel at the palpation portion (30).

[0021]

[0022] The substrate (10) is a long rectangular member and can be made of paper, coated paper, plastic, etc.

[0023]

[0024] The reagent reaction section (20) is a component that is formed on one side (the upper side in FIG. 3) of the substrate section (10) to which a reagent that changes color in response to sugar is applied, enabling visual recognition when sugar comes into contact. Potassium iodide can be used as the reagent, and by generating iodine molecules through the reactions of [chemical formula 1] and [chemical formula 2] below, a color appears when glucose is present.

[0025]

[0026]

[0027]

[0028] The tactile part (30) is a component that allows the user to determine whether or not sugar is contained by the touch of the tactile part (30) by absorbing or collecting the beverage, and is formed under the reagent reaction part (20) of the substrate part (10). The reason why the tactile part (30) is further included in addition to the reagent reaction part (20) in the present invention is to enable the user to determine whether or not sugar is contained by touch in addition to sight, as vision is often impaired due to diabetic retinopathy, a common complication of diabetes.

[0029] The reason why the palpable portion (30) is formed below the reagent reaction portion (20), i.e., near the center of the substrate portion (10), is that users are reluctant to directly immerse the reagent reaction portion (20) in a beverage, so that only one end of the substrate portion (10) is immersed in the beverage and then the substrate portion (10) is raised so that the beverage flows in the order of the reagent reaction portion (20) and the palpable portion (30). If the flowing beverage touches the palpable portion (30) first, the beverage will not reach the reagent reaction portion (20) because it will be absorbed or collected in the palpable portion (30).

[0030] The simplest form of the tactile part (30) may be a polygonal perforation (31) such as a circle, triangle, or square formed on a part of the base part (10), as shown in the partially enlarged view of FIG. 3. If the perforation (31) is smaller than a predetermined size (here, the size may be defined as the length or width of the longest side, etc.), the beverage is collected in the perforation (31) by a capillary phenomenon, and the user can detect a change in viscosity by repeatedly touching both sides of the tactile part (30) with the tip of the finger. That is, if the beverage contains sugar, a significant increase in viscosity can be felt even with only a few repeated contacts, so that the presence or absence of sugar can be determined by the sense of touch.

[0031]

[0032]

[0033] FIG. 5 is another embodiment of a portable glucose test strip for diabetic patients according to the present invention, in which a vertically punched or pressed fold line (11) is formed on the substrate portion (10), so that the user can fold the substrate portion (10) around the fold line (11) and overlap it. In this embodiment, the reagent reaction portion (20) and the palpation portion (30) are formed to be divided on both sides based on the fold line (11), and when the substrate portion (10) is folded so that the reagent reaction portion (20) and the palpation portion (30) are hidden inside the substrate portion (10), one end of the substrate portion (10) can be immersed in a beverage to be measured so that the beverage passes over the reagent reaction portion (20) and the palpation portion (30). In this case, since the beverage can reach the reagent reaction section (20) and the touch section (30) even without setting up the substrate section (10) due to the capillary phenomenon, the inconvenience of having to be careful to ensure that the beverage passes through the reagent reaction section (20) and the touch section (30) when setting up the substrate section (10) in the embodiment of FIG. 3 can be eliminated.

[0034]

[0035] FIGS. 6 to 8 illustrate other embodiments of the tactile part. As illustrated in FIG. 6, the tactile part (30) can be implemented by scratching a portion of the substrate part (10) with a sharp metal or the like to form scratch irregularities (33) of random shape. At this time, fine irregularities are generated by the scratch irregularities (33), and the beverage can be absorbed or collected in the irregularities. For example, if the substrate part (10) is paper or coated paper, the beverage is absorbed, and if it is plastic, the beverage is collected. In this case as well, the change in viscosity can be felt by touching the tactile part (30) with the tip of the finger several times.

[0036] Alternatively, as shown in Fig. 7, by forming a scratch-like depression (33) on a part of the substrate (10) and forming a circular or polygonal perforation (31) in the area where the scratch-like depression (33) is formed, the absorption or collection effect of the beverage can be further increased, and in this case, even a lower sugar concentration can be sensed by touch.

[0037] Fig. 8 is an embodiment in which hexagonal perforations are formed to maximize the ratio of perforations formed, and the touch portion (30) is formed in a honeycomb shape. When the substrate portion (10) is plastic, it is difficult to collect liquid in a part where the perforations (31) are not formed, but when the perforations (31) are hexagonal, the area of ​​the perforations (31) can be maximized within the touch portion (30), so that liquid collection can also be maximized {Even when the perforations (31) are triangular or square, repeated unintended creation is possible, but the portion occupied by the side compared to the area of ​​the perforations (31) is large, which is disadvantageous for liquid collection compared to the case in which the perforations (31) are hexagonal}.
