Description

Test strip {TEST STRIP}

The present invention relates to a test strip.

When a patient visits the clinic, the doctor diagnoses the patient as a premise of the treatment, and diagnoses the patient by various methods of examining the symptoms. In this case, the usual methods of consultation include a patient's history and history of the invention, an examination of the patient's body, a diagnosis of touching the patient's body by hand, a visual examination of the patient's body, I have a stethoscope to listen to and diagnose. In addition to this method of examination, a blood test or a urine test is performed to more accurately determine the type of disease. Urine is a wasted product after blood is filtered from the kidney. It contains various metabolites, so urine can be used to acquire information on systemic endocrine / metabolic diseases as well as urinary tract abnormalities. In addition, urine can be collected non-invasively to the patient as compared to blood sampling, so urine screening is very useful in the medical field. This urine test examines the physical properties such as the color and turbidity of the urine, and detects various kinds of wastes discharged from the urine semi-strategically. At this time, the hue and turbidity are visually examined, and the smell is detected by the smell, and the erythrocytes, white blood cells, bacteria and various crystals are observed using a microscope. In addition, a chemical test using a urine strip for urine testing can be performed, which can be used to easily examine urine protein, urine sugar, and hematuria.

Such a urine analyzer using a urine test finger is disclosed in the following prior art documents. In the conventional urine test, the reaction part for various items is made in advance, and the urine is immersed in the urine, and the disease is read through the change of the color of the reaction part after a predetermined inspection time has elapsed. At this time, the reading of the disease is visually checked against the color chart and the color provided by the manufacturer, or a dedicated reading machine is used.

The most important point in the test using the conventional urine test finger is to observe the test time exactly. At this time, the most important thing is to observe the inspection time precisely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of related arts which may unnecessarily obscure the gist of the present invention will be omitted.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a test strip according to a first embodiment of the present invention, and FIGS. 2A and 2B are enlarged views of a circle A shown in FIG. 1. FIG.

1, a test strip according to a first embodiment of the present invention is formed in a plate shape having a predetermined length and includes a test sheet 10 in which one end 11 is immersed in a test liquid 1, A reagent pad 20 disposed on one surface of the test sheet 10 and discolored in response to the test liquid 1 is disposed on the test sheet 10 along the longitudinal direction of the test sheet 10, (30) for moving the test liquid (1) absorbed at one end when the test liquid (10) is immersed in the other end direction and the test liquid (1) corresponding to the moving distance of the test liquid And a time scale unit 40 for indicating an inspection time.

The test strip according to the present embodiment includes a test strip 10 for analyzing the components of the test liquid 1, a reagent pad 20, a flow portion 30, and a time scale portion 40 .

In the course of diagnosing the patient, the patient's disease is judged and urine test, saliva test, and blood test are performed to check the symptoms. Urine is a wastewater from the blood of the kidneys, which contains various metabolites. Therefore, the urine test can easily acquire information on systemic endocrine / metabolic diseases as well as urinary tract abnormalities. Saliva tests can measure a variety of hormones, especially for diagnosing adrenal pyrexia. Blood tests are the most common tests that can be used to determine blood cell count and normal physiological function. In order to perform this inspection method non-invasively and simply, a test strip according to this embodiment has been devised. That is, the test strip according to the present embodiment is used for reading the target disease by analyzing the urine, saliva, or blood as the test liquid (1). Since the component analysis of the test liquid 1 is based on the color change of the reagent pad 20 as long as the components of the test liquid 1 are discolored through a chemical reaction with the reagent pad 20, Various types of test liquid (1) can also be judged. Therefore, the test liquid 1 is not necessarily limited to urine, saliva, or blood, but may include any substance that reacts with the reagent pad 20 to discolor such as drinking water, alcohol, or gasoline have.

Here, the test sheet 10 is formed into a plate having a predetermined length as a support. In order to inspect the test liquid 1, one end 11 of the test sheet 10 is immersed in the test liquid 1 contained in the container or the like. At this time, one end 11 of the test sheet 10 is immersed in the test liquid The test sheet 10 is placed on a table or a test stand so that the color change of the reagent pad 20 can be prevented from being changed You can observe.

The reagent pad 20 is a reaction part that is discolored by the test liquid 1 and is disposed on one surface of the test sheet 10 as a support. Here, the reagent pad 20 can be disposed at a predetermined position on the test sheet 10 so that one end of the test sheet 10 is immersed together when the test liquid 1 is immersed in the test liquid. However, since the test liquid 1 absorbed at one end of the test sheet 10 can move along the test sheet 10, it is not necessarily limited to the position where it can be immersed together with the test sheet 10. At this time, the test liquid 1 may move along the texture of the material due to the material characteristics of the test sheet 10 or may move through the hollow channel penetrating from the one end of the test sheet 10 to the reagent pad 20 (Not shown).

The chemical agent is contained in the reagent pad 20, and its color changes when reacted with a specific component of the test liquid (1). For example, when the test liquid (1) is urine, the metabolite contained in the urine of the patient having a specific disease differs from that of a normal person in the concentration or kind thereof. Therefore, the reagent pad ) Exhibit a color different from that of the reagent pad 20 that responds to urine of a normal person. Therefore, it is possible to judge the components of the test liquid 1 or the like through the color change of the reagent pad 20 or to judge the target disease. At this time, in determining the color of the reagent pad 20, the inspection time required for the determination must be strictly observed. This is because, depending on the type of the liquid 1 to be tested and the purpose of the test, the test time may be several seconds to several minutes. For example, in the case of a urine test, the target disease is determined based on the color determined within 60 to 120 seconds. That is, the color of the reagent pad 20 depends on the type of the liquid 1 to be inspected and the inspection time. Therefore, it is strictly required to observe the inspection time in order to perform an accurate inspection. The inspection strip according to the present embodiment can measure the inspection time without using a separate timer through the flow unit 30 and the time scale unit 40 .

The flow portion 30 is a channel through which the liquid 1 to be inspected flows. Here, the fluid 30 is disposed on the test sheet 10 along the longitudinal direction of the test sheet 10 so that the test liquid 1 flows in one direction and is moved in the other end direction. At this time, the liquid 1 to be inspected is moved by the capillary force generated in the fluid 30. Specifically, the flow portion 30 may be formed as a rectangular plate having a predetermined width and length as a porous material. At this time, since paper can be used as a representative porous material, the paper can be cut in a rectangular shape to form the moving part 30. [ Since the paper is made of cellulosic fiber, it generates capillary force through numerous pores without any additional equipment to transport the test liquid (1). However, the porous material is not necessarily limited to the species, but may include any material as long as the liquid can permeate along the inside thereof by the capillary force, such as fabric, cotton, fiber, May also be formed of various materials without necessarily being formed of paper. The test liquid 1 moving along the flow portion 30 moves at a predetermined speed and the inspection time can be measured by disposing the off-time graduation portion 40 in accordance with the movement distance.

Here, the time scale unit 40 includes a time scale 41 indicating the time converted from the movement distance of the test liquid 1. When the time scale 41 is displayed in accordance with the moving distance, the liquid 1 to be inspected moves within the moving part 30 at a predetermined moving speed for a predetermined time, The moving time can be immediately confirmed. At this time, the liquid 1 to be inspected flows into one end of the flow section 30, and the inspection is started from that time. Therefore, when one end of the liquid 1 is taken as a reference point of time, the time recognized from the time scale 41 becomes the inspection time .

In view of this fact, one end of the fluid 30 and the reagent pad 20 can be arranged side by side so that the inspection time is measured simultaneously with the reaction of the reagent pad 20. That is, one end of the flow portion 30 and the reagent pad 20 are disposed on the same parallel line (l) parallel to the one end 11 of the test sheet 10, so that the test liquid 1 is simultaneously supplied to the reagent pad 20 And the one end of the moving part 30 so that the time scale part 40 measures the reaction time of the reagent pad 20. As described above, since the test liquid 1 is absorbed by the reagent pad 20 through the structure of the test sheet 10 or the hollow channel, or the other configuration can be added, And the reagent pads 20 need not be arranged side by side.

On the other hand, the time scale 41 may be displayed on one side of the inspection sheet 10 or on the outer surface of the fluidization section 30. The interval of the time divisions 41 may be linear depending on the shape of the fluidization section 30 , Or non-linearly. This will be described in detail below.

Depending on the type of the liquid 1 to be tested, the velocity of the liquid 1 to be moved along the fluid 30 may be variable. In other words, the liquid 1 to be tested moves at a constant speed from one end to the other end of the moving part 30 during the inspection time, while the liquid 1 to be tested, whose speed is greatly decreased as moving away from one end of the moving part 30 have. In the case of the velocity variable test liquid 1, the moving distance varies greatly at the same time intervals, and the time error through the time scale 41 is excessively generated. As a compensation method, the test strip according to the present embodiment displays the interval of the time scale 41 nonlinearly or adjusts the width of the moving part 30, and each case will be described in detail.

The interval between the time scales 41a, 41b and 41c of the time graduation unit 40 may become gradually narrower toward the other end direction of the fluid 30 as shown in FIG. When the width w of the moving part 30 is constant, the moving distance of the speed varyable test liquid 1 moving for the same time becomes shorter toward the other end of the moving part 30. The interval L ₂ between the two time scales 41b and 41c adjacent to the other end of the fluid 30 is smaller than the interval between the two time scales 41a and 41b close to one end of the fluid 30 to relatively shorter than that (L _1), by placing the time scale (41a, 41b, 41c), to compensate for the time offset according to the variable speed. Alternatively, the time scales 41a, 41b, and 41c may be maintained at equal intervals while canceling the time error, which will be described below.

As shown in FIG. 2B, the width w of the flow portion 30 is gradually narrowed toward the other end direction, so that the time error can be canceled. Since the cross-sectional area of the fluid portion 30 is larger than that of the narrow portion, the area of the pores through which the liquid 1 to be inspected passes is wider. At this time, the moving speed of the test liquid 1 is faster at a portion having a relatively small pore area, that is, at a portion having a narrow width w, so that the width w of the moving portion 30 in the other end direction is narrowed, The liquid 1 to be tested moves at a constant speed. The distance L ₂ between the two time scales 41b and 41c close to the other end of the moving part 30 and the time L ₂ between the two time scales 41b and 41c close to the other end of the moving part 30, Accurate time measurement becomes possible even if the intervals L ₁ between the scales 41a and 41b are the same.

As a result, according to the inspection strip according to the present embodiment, since the moving part 30 and the time scale 41 are disposed on the inspection sheet 10, the inspected strip 10 flows into the moving part 30, It is possible to easily check the inspection time with the naked eye without using a separate timer by converting the moving distance of the apparatus 1 into the time through the time scale 41. [ In addition, the intervals of the time scales 41 are arranged in a nonlinear manner, or the width of the flow portion 30 is gradually narrowed, thereby canceling the time error due to the moving speed varying with the passage of the inspection time, The accuracy of the test can be improved.

3 is a perspective view of a test strip according to a second embodiment of the present invention.

As shown in FIG. 3, the test strip according to the second embodiment of the present invention may further include a coating layer 50. The coating layer 50 is a thin film layer made of a hydrophobic material and covers one surface of the flow portion 30. Here, one surface of the fluid 30 is opposite to the surface contacting the test sheet 10, that is, the surface exposed to the outside. A hydrophobic substance is applied or printed on one surface of a fluid portion 30 made of a porous material such as paper to form a coating layer 50 so as to control the permeability of the fluid portion 30, Can be controlled. The coating layer 50 is formed in such a manner that the liquid 1 to be inspected does not intrude into the center of the fluid portion 30 due to a user's mistake or the like even though the liquid 1 to be inspected should flow from one end of the fluid portion 30, Thereby preventing the foreign matter that influences the inspection from contacting the fluid 30. Here, since the hydrophobic substance may be, for example, a wax or a polymer series, the coating layer 50 may be formed by printing wax by wax printing or by casting and drying the polymer ink. Here, the polymer may be, for example, polystyrene, but is not limited thereto. In addition, the hydrophobic substance is not limited to the wax or polymer series, and may include various substances having hydrophobicity, such as SU-8 or alkenyl ketene dimer.

In addition, the inspection strip according to the present embodiment may further include a color- Here, the colorimetric table 60 is a table in which the various display colors 61a and 61b of the reagent pad 20 in response to the test liquid 1 are aligned. At this time, since the display colors 61a and 61b constituting the colorimetric table 60 are predetermined colors according to the components of the disease or the test liquid 1, the color of the reagent pad 20 is compared with the colorimetric table 60 , The disease or the liquid sample (1) can be judged immediately. Here, the display colors 61a and 61b are arranged adjacent to each other along the edge of the reagent pad 20, and the reagent pad 20 and the colorless table 60 are paired one on top of the other, Or more. In the case of being arranged in a plurality of pairs, it is possible to determine various diseases or components to be tested (1) by one inspection, thereby shortening inspection time and improving inspection efficiency.

In addition, the test strip according to the present embodiment may further include a reservoir 70. Here, the reservoir 70 temporarily stores the test liquid 1 when the test sheet 10 is immersed in the test liquid 1. Specifically, the reservoir 70 may be formed in various forms and materials, such as a form of a container, or a pad form capable of absorbing the test liquid 1 as a porous material, as long as the test liquid 1 can be stored. Since the reservoir 70 is connected to one end of the fluid 30, the liquid 1 temporarily stored in the reservoir 70 is absorbed through one end of the fluid 30.

In the above-described embodiment, the moving part 30 is formed of a porous material, but it may be formed in the shape of a hollow tube. Hereinafter, related parts will be described.
