Title: Apparatus and Method for Analyzing Urine Components in Toilet in Real-Time by Using Miniature ATR Infrared Spectroscopy

Description:
TECHNICAL FIELD 
     The present invention relates to an apparatus and a method for analyzing urine components which can measure concentrations of components contained in the urine, and more particularly, to an apparatus and a method for analyzing urine components in real-time which can measure concentrations of components contained in the urine by using an Attenuated Total Reflectance Infrared (ATR-IR) spectroscopy. 
     The present invention relates to an apparatus and a method for measuring and analyzing the urine in the toilet in real-time, and more particularly to develop a miniature infrared spectrometer which may be used even in special environments such as the toilet and an Attenuated Total Reflectance (ATR) which can collect a urine sample effectively and measure it reproductively, as well as attach the miniature ATR infrared spectroscopy on the toilet effectively. Further, the present invention provides an effective algorithm which can measure and analyze Glucose, Creatine, Urea, Protein, Albumine, PH, Triglyceride, Cholesterol, Bilirubin, Uric acid, and Nitrite which are urine components contained in the urine using the miniature ATR-IR attached on the toilet. 
     BACKGROUND ART 
     Generally, methods of inspecting urine components using the visible ray have been used. The components contained in urine are analyzed using 3 wavelengths in a visible ray region, and at this time the inspection has been mainly performed by a urine test-paper. Since the method needs to use the urine test-paper which is disposable, users need to repeatedly purchase separate test-papers to measure urine components everyday. The user feels inconvenience when allowing the urine test-paper to be wet with the urine. Also, it is difficult to keep equipments including the urine test-paper in general home and thus supply it to general person. 
     A spectroscopy analyzing method is used as a method which does not use the urine test-paper, and at this time it is possible to analyze various components in the urine using an infrared spectroscopy. However, there is no case that the infrared spectroscopy is attached on the toilet since the infrared spectroscopy analyzing apparatus is too large to be attached on the toilet directly. Since a signal-to-noise ratio (SNR) is reduced along with miniaturizing the infrared spectroscopy, it is not possible to effectively analyze Glucose, Creatine, Urea, Protein, Albumine, PH, Triglyceride, Cholesterol, Bilirubin, Uric acid, and Nitrite which are urine components contained in a urine sample. Also, an automatic cleaner is required to be provided with the toilet since the user may not clean the sample after measuring it every time, and mixed components may not be measured effectively due to an effect of moistures in the infrared region. 
     As another spectroscopy method, a method of introducing the sample using a separate apparatus which introduces the sample from the toilet is used, and the apparatus is structured in a light-transmitting manner by causing an apparatus for analyzing the introduced sample, a light source and a detector to be arranged in parallel (180 degrees). The method needs an additional facility and particularly the light used in the method corresponds to near-infrared ray. A wavelength band used in the analyzing apparatus using the near-infrared ray is in a range of 800 nm to 2,500 nm. The light in the wavelength band is suitable for analyzing a single component among components contained in the urine, whereas measures for multiple components are overlapped in a case of analyzing multiple components contained in the urine, which results in difficulty in analyzing the multiple components. Consequently, there is a need for an apparatus and a method for easily and precisely analyzing multiple components contained in the urine. 
     Further, there is a problem in that the users or patients need to measure the urine component, a blood pressure and a body fat at different positions in different times since they do not have an apparatus for analyzing the urine components and measuring the blood pressure and the body fat by doing simple actions while sitting on the toilet.

     BEST MODE FOR CARRYING OUT THE INVENTION 
     Practical and presently preferred embodiments of the present invention are illustrative as shown in the following Examples and Comparative Examples. 
     However, it will be appreciated that those skilled in the art, on consideration of this disclosure, may make modifications and improvements within the spirit and scope of the present invention. 
       FIG. 1  is a perspective view showing a health diagnostic system including a urine component analyzing apparatus  700  according to one embodiment of the present invention. Referring to  FIG. 1 , the health diagnostic system includes a blood pressure measuring apparatus  100 , a bidet control apparatus  200 , a fingerprint recognition apparatus  300 , a monitor  400 , a main control apparatus  500 , a body fat measuring apparatus  600 , a urine component analyzing apparatus  700 , a medicine input apparatus  800  and a weight measuring apparatus  900 . 
     In  FIG. 1 , even though it is shown that the blood pressure measuring apparatus  100  is rectangular-shaped or open cuff-shaped and is positioned on a top surface of a leg-support member  1000 , the present invention is not limited to the shape and the position of the blood pressure measuring apparatus  100 . 
     Further, the health diagnostic system measures a weight using the weight measuring apparatus  900  and measures a body fat using the body fat measuring apparatus  600 . 
     Meanwhile,  FIGS. 2 to 4  show external perspective views showing the health diagnostic system of various models including the urine component analyzing apparatus  700  according to still another embodiment of the present invention. 
     The body fat measurement is to be initiated once a user grasps a handle  609  of the body fat measuring apparatus  600  having electrodes  601  to  608  embedded in left and right sides on a top portion of the toilet  710  after sitting on the toilet  710 . Hereinafter, the body fat measuring apparatus  600  will be specifically described referring to  FIGS. 5 and 6 . 
     A method for measuring the body fat will be described specifically. Once a button of a “body fat measurement” is pressurized, the pressure sensor of the weight measuring apparatus  900  is operated to measure the weight. Then, the user pressurizes a button of “start” and extends both legs down while sitting on the toilet  710  to grasp the handle  609  of the fat body measuring apparatus  600 . When the fat body measurement is completed, corresponding information such as a body fat percentage and an amount of muscles are displayed on a monitor  400  using an age, a sex distinction and a height of the user which are saved in advance and the weight measured by the weight measuring apparatus  900 . If the weight information is already acquired, the weight measurement procedure may be omitted. 
     The monitor  400  may be projected in such a manner that it is rotated in horizontal direction about one axis held from bottom surface of the leg-support member  1000 . 
     Further, the health diagnostic system measures sugar, protein and blood contained in the urine using the urine component analyzing apparatus  700  to display them on the monitor  400 . The specific description of the urine component analyzing apparatus  700  will be specifically described referring to  FIG. 2  to  FIG. 6 . 
     Further, the health diagnostic system includes the medicine input device  800  positioned on the backside of the urine component analyzing apparatus  700 . A medicine such as cleaning agent and aromatic may be input through the medicine input device  800 . The medicine input device  800  may be structured such that it is allowed to be correctly combined with the medicine case and tilted slightly to cause the medicine to be dropped down easily. Therefore, the medicine case may be inserted into the medicine input device  800  and then removed from the medicine input device  800  when all of the medicine is consumed. The medicine input device  800  is connected to the bidet device and the medicine input to the medicine input device  800  is sprayed via the bidet device. 
       FIG. 5  shows the body fat measuring device  600  composing the health diagnostic system according to one embodiment of the present invention. Referring to  FIG. 5 , the body fat measuring device  600  has four electrodes  601 ,  602 ,  603 ,  604  provided on a toilet seat of the toilet  710  and two electrodes  605 ,  606 ,  607 ,  608  provided on both handle  609  respectively, so that the body fat may be measured using total eight electrodes  601 ,  602 ,  603 ,  604 ,  605 ,  606 ,  607 ,  608 . 
     In other words, a voltage electrode and a current electrode are provided on each handle  609  of left side and right side of the toilet  710 , and additional four electrodes (two voltage electrodes and two current electrodes) are provided on a contact portion of hips or femoral region with the top portion of the toilet  710 , in which two electrodes (voltage electrode and current electrode) compose one contact point. 
       FIG. 6  shows the handle  609  of the body fat measuring device  600  according to one embodiment of the present invention. Referring to  FIG. 6 , the handle  609  of depression type may be provided on both sides of the toilet  710  and put on with a cover  611  to prevent water from being wet. Further, the cover  611  may be provided with a slit  610  on its lower side so that the water entering into outer surrounding grooves may leak out. 
       FIG. 7  shows a Fourier Transform infrared spectroscopy used in general laboratory. Referring to  FIG. 7 , the infrared spectroscopy is divided into a light source unit  741 , a beam splitter  742 , a first reflecting mirror  743 , a monochromator (not shown), a sample measuring unit  744 , a second reflecting mirror  745  and a detector  746 . 
     In a case of using prior infrared spectroscopy shown in  FIG. 7 , since its size reaches 20 to 50 cm and its weight reaches 10 kg, it is difficult to apply it to small space such as the toilet  710  according to an embodiment of the present invention. 
     Generally, as the light generated from the infrared light source unit is far away from the light source, it is dramatically decreased proportionally to an inverse of the square of the distance. In prior large Fourier Transform Infrared (FT-IR) spectroscopy, it needs to perform complex procedures such as using the light source of high output and adjusting the frequency via a chopper to prevent diffusion of the light and background noise or using a monochromator or an interperometer additionally, in order to achieve high signal-to-noise ratio. However, in the toilet  710 , it is not possible to use the chopper, the monochoromter or the interperometer since the analyzing unit  750  needs to be provided in the small space. Therefore, when the heat-generating area of a single-structured radiating plate of the light source unit is attempted to be increased for the purpose of obtaining adequate light from the small light source, the response time is increased and therefore it is impossible to be detected at the detector. Further, there is a problem that it is difficult to transmit adequate light to the ATR when reducing the output of the light source to reduce the size of the radiating plate. Even though there is an attempt to use the infrared spectroscopy to analyze the urine components, suitable and reliable results may not be obtained in a range of mid-infrared ray. 
     In order to address such problems, the present inventors contemplate a scheme which can increase the signal-to-noise ratio while miniaturizing the analyzing apparatus, i.e., synchronize pulse frequency of the light source to one of the detector  755  while decreasing a loss of the light amount and increasing an intensity of the light, upon mounting the analyzing apparatus on small space such as the toilet  710 . Such adequate design scheme includes a technology which takes a line sensor in a light-receiving unit  762  of the detector  755  capable of receiving a desired spectrum. Herein, the frequency synchronization technology includes a technology which controls the frequency synchronization of signals from the light source and the detector  755  sensor by a Central Processing Unit (CPU). 
       FIG. 8  is a conceptual view which explains internal spectroscopy analyzing principle of the analyzing apparatus according to an embodiment of the present invention. According to the present invention, surface shapes of the light source unit  751 , the ATR, the filter  761  and the light-receiving unit  762  (line sensor) of the detector  755  are made to correspond similarly to one another, for the purpose of miniaturizing the analyzing apparatus and minimizing a loss of the light. In other words, if the corresponding surface of the light source unit  751  is of rectangular shape having large aspect ratio, ATR prism  753 , mirror or tapered rod, a linear variable filter  761  (LVF), and the light-receiving unit  762  (line sensor) of the detector  755  through which the generated light is transmitted are also of rectangular shape. 
     The analyzing apparatus according to the present invention maximizes the signal-to-noise ratio and increases the intensity of the light generated from the light source unit  751  while preventing nonconformity of the pulse wavelength without delay of response time at the detector  755 . For the purpose of it, the analyzing apparatus has materials, polishing feature, arrangement degree and distance between the components which are determined to cause each component to exhibit optimum performance. 
       FIG. 9  shows one embodiment of the analyzing apparatus according to the present invention. The light source unit  751  of the analyzing apparatus has a length of 13 to 14 mm and a width of 3 to 4 mm, the ATR prism  753  has a length of 13 to 14 mm and a width of 3 to 4 mm, and the light-receiving unit  762  (line sensor) of the detector  755  has a length and a with of 12 mm and 2 mm, respectively. 
     The concept of such embodiment is such that a shape of sensor in the detector  755  corresponds similarly to shapes of the light source unit  751  and the prism  753  in order to minimize a loss of the light in hardware. 
     The distance between the light source unit  751  and the prism  753  is in a range of 300 μm to 5 mm and the distance between the prism  753  and the detector  755  is in a range of 300 μm to 5 mm. A total trace until the light generated from the light source unit  751  reaches the detector  755  through the prism  753  is in a range of about 10 to 30 mm. However, when a mirror tunnel  759  or taper rod is provided between the prism  753  and the detector  755 , the total trace is preferably in a range of about 10 to 50 mm. Generally, since the intensity of the light is decreased proportionally to an inverse of the square of the distance of the light source and the light is spread over surrounding region, the analyzing apparatus according to the present invention preferably is such that a light path should be kept as short as possible. 
     The design concept of keeping the distance between each component within a prescribed range is to prevent the intensity of the light from being attenuated proportionally to the square of the propagating distance and ultimately to optimize the SN ratio for the purpose of minimizing a loss of the light. 
     The present invention makes it possible to miniaturize the analyzing apparatus and to attach it on small space such as the toilet  710 , by making the distance between the components or total traces of the light source very short without a need for providing a separate driving equipment which is necessary for the existing large FT-IR equipment. 
       FIG. 10  shows main components of the analyzing unit  750  according to an embodiment of the present invention. The analyzing unit  750  according to the present invention is structured such that cross-sectional shapes vertical to the light path at the light source unit  751 , the prism  753  the light-receiving unit  762  (line sensor) of the detector  755  may correspond similarly to one another in order to keep the loss of light low and the SN rate high. 
     In  FIG. 10  shows that the light source unit  751  is of rectangular shape and also the light source generated from the light source unit  751  is incident into the prism  753  with the cross-sectional surface of rectangular shape in advance direction, and the prism  753  is of rectangular shape similar to the cross-section surface of the light source unit  751  not to cause a loss of the incident light source. After the light source is incident into the prism  753  and refracted, the reflected light source is of rectangular shape having cross-section surface vertical to the advance direction and finally entered into the detector  755 . The light-receiving unit  762  of the detector  755  is also of rectangular shape not to cause a loss of the light source. Due to such structure, since the light source generated from the light source unit  751  can reach the light-receiving unit  762  via the prism  753  without a loss, it may be used in the miniature analyzing apparatus efficiently. 
     In  FIG. 11  is a conceptional view according to another embodiment showing that a combination of the light source unit  751 , the prism  753 , and the light-receiving unit  762  of the detector  755  makes a round shape. In  FIG. 12  is a conceptual view according to still another embodiment showing a combination of the light source unit  751 , the prism  753  and the light-receiving unit  762  of the detector  755  makes a triangle shape. At this time, the prism  753  may be of any shape if it has an incidence plane and an emittance plane opposite to each other with a prescribed degree. For example, it may be a triangular prism  753  shape. Further, whatever the light source unit  751 , the prism  753  and the light-receiving unit  762  of the detector  755  correspond similarly to one another belong to a scope of the present invention. 
       FIG. 13  and  FIG. 14  are perspective views showing the analyzing unit  750  of the urine component analyzing apparatus  700  according to an embodiment of the present invention. Referring to drawings including  FIG. 13  and  FIG. 14 , the analyzing unit  750  includes a light source unit  751 , a reflecting mirror  752 , a prism  753 , a light inductor  754 , a detector  755 , and a controller  756 . In the analyzing unit  750  according to the embodiment, the ATR is composed of the prism  753  and the light inductor  754 . The analyzing unit  750  according to the embodiment is miniaturized to allow it to be used as a sensor for measuring urine, and simultaneously is structured to increase the signal-to-noise ratio. 
       FIG. 13  and  FIG. 14  show one embodiment of the present invention, in which the light source unit  751  may be of multi-array structure by arranging a plurality of small light sources of low power in one array or multiple arrays to increase a life-time of the light source unit  751  while increasing the signal-to-noise ratio. Though spectroscopy analysis may use a method for increasing the intensity of the light source by using a halogen lamp or increasing a size of the radiating plate, there is a problem that a response time at the detector  755  is delayed so that it may not perform correct sensing since the single radiating plate is big-sized. In order to address the problem, the light source unit  751  according to the present invention forms a linear light source unit  751  of array shape by arranging a plurality of radiating units having small heat-generating area in one array. In other words, it is possible to overcome the problem with the response time being delayed at the detector  755  by arranging 10 or more small radiating units of 1 mm×1 mm or 5 or more small radiating units of 1.5 mm×1.5 mm in one array. 
     That is, by making a size of each radiating unit in the plurality of small radiating units (light source unit  751 ) smaller as compared with prior art, it is possible to improve a modulation depth without a problem in light-radiating function even though on/off are performed several tens times per a second and to controllably synchronize light signals (pulse) of the light source unit  751  and the detector  755  by a CPU controller  756  in a software. The structural durability may be improved by using platinum as a material of the light source unit  751  even though on/off are performed several tens times per a second, which results in overcoming the problem with the light-radiating capability being decreased. 
     Further, the array structure of the light source unit  751  may be consisted of two arrays so that the pulse from the light source unit  751  may synchronize to one from the detector  755 . This is for the purpose of keeping intensity of the light source high and synchronizing the signal wavelength of the light source reaching the light-receiving unit  762  of the detector  755 . 
     The analyzing unit  750  of the present invention may not use the chopper due to a structural characteristic that it is attached on small space such as the toilet  710 . Instead, the light source unit  751  uses multiple light sources of low output and linear multi-array light lay. For the purpose of miniaturizing the analyzing apparatus, a linear variable filter  761  (LVF) is provided at a front end of the detector  755 . The linear variable filter  761  is produced via Micro-Electro-Mechanical Systems (MEMS) technology. 
     The ATR is one method for obtaining the infrared spectrum of the sample  758  which is difficult to be treated in general absorption spectroscopy, which is an analysis method or an analysis apparatus used to measure solid, film, fiber, paste and adhesive and/or powder sample  758  of low solubility. 
     When the light passes from dense medium to coarse medium, the reflection occurs typically. At this time, the reflection rate of the incident light is increased when the incidence degree is increased, and total reflection takes place when it excesses any threshold degree. 
     When such reflection takes place, it is known experimentally and theoretically that the light acts like penetrating into the coarse medium by a small distance. At this time, penetrating depth of the light is varied in a range of several tenths wavelengths to several wavelengths. Specifically, when causing the urine sample  758  to wet a surface of the ATR exposed to the toilet  710 , the light is passed to the sample  758  via the ATR. 
     As mentioned earlier, the ATR machine may be properly used to measure the solid, film, fiber, paste and adhesive and/or powder sample  758  of low solvability and to analyze the solution due to advance of materials resistant to water solution such as diamond or ZnSe. Typically the reflection takes places when the light passes from the dense medium to the coarse medium, and at this time, the reflection rate of the incident light is increased if the incidence angle is increased and total reflection takes place if it exceeds any threshold degree. When such reflection takes places, it is known experimentally and theoretically that the light acts like penetrating into the coarse medium by a small distance. At this time, penetrating depth of the light is varied in a range of several tenths wavelengths to several wavelengths. 
     The final penetration depth depends on a wavelength of the incident light, refractive index of two materials and the incidence degree to interface surface. The penetrating radiant light is referred to an evanescent wave. The light of absorption band wavelength is attenuated when the coarse medium absorbs the evanescent wave. The light passing the prism  753  is introduced into the detector  755  through the LVF (not shown) via an optimum optical system by the light inductor  754  such as a tapered rod. The light detected by the detector  755  is converted into the digital signal by the controller  756  to be measured. The controller  756  measures the data detected and controls each portion electronically. 
       FIG. 14  is a perspective view showing that a spectroscopy module  760  is attached to the toilet  710 . 
       FIG. 15  is a cross-section view showing that the light passes the analyzing unit  750  of the urine component analyzing apparatus  700 . Referring to  FIG. 15 , the light generated at the light source unit  751  is reflected at the reflecting mirror  752  surrounding the light source unit  751  and incident into the ATR prism  753 . An interior of the reflecting mirror  752  is formed in a parabola shape, and the light source unit  751  is located in a focus portion of the parabola so that the light generated by the light source unit  751  is reflected on the reflecting mirror  752  and incident into the ATR prism  753  as a parallel light. Even though the reflecting mirror  752  of parabolic shape is shown in  FIG. 15 , the present invention is not limited to it. 
     The light  757  incident into the ATR prism  753  is totally reflected after a portion of the wavelength is absorbed by the sample  758  at an inclined plane of the ATR prism  753  and introduced into the detector  755  through the light inductor  754  (tapered rod). The detector  755  senses the intensity of the light introduced. The analyzing unit  750  according to the present invention can increase the total intensity of the light greater than when using one light source of high output by using several light sources of low output and overcome a problem of the intensity of the light being dramatically reduced by using the parallel light. 
     Though not shown specifically, the analyzing unit  750  is depressed downwardly on a basis of an internal side of the toilet  710  when the analyzing apparatus  750  is attached on the toilet  710 , because the urine may be analyzed only when a prescribed amount of it is on the prism  753 . 
     The analyzing unit  750  may be primarily cleaned using cleaning solution of the toilet  710  after excretion and secondly cleaned using an air injection device  720  which is separately provided at the toilet  710 . The air injection device  720  is preferably mounted within the toilet  710  and provided at a degree suitable to cause the air to be injected to the analyzing unit  750  correctly. 
       FIG. 16  is an external perspective view showing the spectroscopy module  760  which is applied to the analyzing apparatus  750  according to still another embodiment of the present invention, and  FIG. 15  is a side cross-sectional vies of the spectroscopy module  760  of  FIG. 16 . 
       FIG. 20  is a drawing showing a principle of the reflecting mirror  752  shown in  FIG. 18  and  FIG. 19 , and  FIG. 13  is a perspective view of the reflecting mirror  752  according to an embodiment of the present invention. Referring to  FIG. 20  and  FIG. 21 , the light generated by the light source unit  751  is reflected on the reflecting mirror  752  of parabolic shape and incident into the ATR prism  753 . The reflecting mirror  752  of parabolic shape is calculated using an equation 1 below.

     wherein c is a curvature (=1/r (radius of curvature)), k is conic constant, and y is a height in an optical axis. 
     The reflecting mirror  752  is of cylinder-shape having r value of 2 mm, k value of −1, and maximum external diameter of 4 mm. That is, it has a parabolic shape in direction of y axis and an elongate shape (14 mm) in a direction of x axis. The light reflected by the reflecting mirror  752  is introduced into the prism  753 . Since the cross-sectional shapes of the light source unit  751 , the prism  753  and the receiving of the detector  755  are structured similarly to one another, it is possible to prevent a loss of the light source and thus increase efficiency. 
       FIG. 22  and  FIG. 23  are drawings showing conditions which cause the light to be reflected totally at the prism  753 . As mentioned earlier, the light  757  incident into the prism  753  has wavelength of one portion absorbed into the sample  758  at a slanted plane of the prism  753  and remaining reflected totally. In  FIG. 22 , the light incident into the slanted plane with a degree of i conforms to Snell&#39;s law according to an equation 2 below. 
       n sin i=n′ sin i′  [Equation 2]
 
     wherein, n is a refractive index (3.43) of the medium and n is a refractive index (1) of the air. In order to cause the light to be reflected totally within the prism  753 , i′ needs to be lower than 90 degree (in this case, sin i′=1) which is vertical to the normal line of the slanted plane of the prism  753 , and at this time i is calculated according to an equation 3 below. 
         i =sin −1 ( n′/n )  [Equation 3]
 
     Even though the value of i calculated via an experiment is about 17 degree, the present invention is not limited to it. Therefore, if i is greater than 17 degree, the light is totally reflected on the slanted plane of the prism  753 . According to the present invention, since the light is incident with i of about 45 degree, most light is totally reflected on the slanted plane of the prism  753 . The shape of the prism  753  is of a triangular shape having a length in x-axis direction of 14 mm and a cut-away surface of equilateral triangle. The light reflected totally on the prism  753  is introduced into the detector  755  via the light inductor  754 . 
       FIG. 23  is a drawing illustrating a principle that the light is delivered via the light inductor  754 . The light inductor  754  is a glass block having 6 polished surfaces which are slightly slanted and narrowed downwardly. As shown in  FIG. 23 , the light incident into the light inductor  754  is totally reflected in the inside of it and delivered, and at this time, it also conforms to the Snell&#39;s law. Therefore, when the inclination of the slanted surface of the light inductor  754  is steep, the total reflection condition is broken so that the light ray may be emitted out of the light inductor  754 , and therefore the inclination of the slanted surface needs to be adjusted properly. 
     It is possible to use a mirror tunnel  759  instead of the light inductor  754 . Even in a case of using the minor tunnel  759 , if a degree of inclination is large, the light may be reflected on the inside of the mirror tunnel  759  and turned back, and therefore the inclination of the slanted surface needs to be adjusted properly. The light is totally reflected on the light inductor  754 , whereas the light is reflected 90% on the mirror tunnel  759 , which results in reducing the amount of the light by about 10% whenever reflection occurs. 
       FIG. 24  is a graph showing the intensity of the light generated by the light source and  FIG. 25  is a graph showing the intensity of the light measured by the detector  755  if the distance between the light source unit  751  and the detector  755  is 1 mm. Referring to  FIG. 24 , the light generated by the light source unit  751  and passing through the reflecting mirror  752  is equally measured. However, since the intensity of the light is dramatically reduced if the distance is greater than 5 mm, the distance between the light source unit  751  and the ATR is made lower than 5 mm to allow maximum light to be introduced into the ATR. More preferably, the distance may be selected in a range of 0.5 to 3 mm considering the organic characteristic. Consequently, it is possible to miniaturize the mid-infrared spectroscopy apparatus which is capable of being mounted on small space such as the toilet  710 . 
       FIG. 25  shows the intensity of the light measured by the detector  755  when using the mirror tunnel  759  of diamond shape (13×3×27 mm) to deliver the light emitted from the ATR into the detector  755  efficiently. 
       FIG. 26  is a flow diagram showing a method for analyzing the urine components using the urine component analyzing apparatus  700 . Referring  FIG. 26 , it operates the analyzing system including the analyzing unit  750  of the urine component measuring apparatus  700  according to the present invention S 1010 . Then, the reference material is introduced into the analyzing unit  750  and the analyzing unit  750  measures a reference spectrum S 1020 . The reference material contains water. 
     Then, the sample is directly introduced into the ATR via a urine collector within the toilet stool  710 . Then, the analyzing unit  750  including the ATR and the complex filter  761  measures the absorption spectrum using the sample introduced S 1030 . The absorption spectrum represents a certain wavenumber absorbed than the reference material as compared with the reference spectrum and the computation equation is calculated by log (reference spectrum/sample spectrum). 
     Then, it acquires a measuring line representing a correlation between the absorption spectrum and a standard value obtained by measuring each component of the sample S 1040 . It is possible to estimate the value of each component contained in the sample by substituting the absorption spectrum of the sample for the measuring line S 1050 . Generally, the measuring line has been already saved in the computer by confirming the correlation using the standard urine component and virtual value and then confirming R̂2 and SEC which are statistical criterion for the correlation. 
     Such total procedures are referred to a routine analysis. An important thing in the routine analysis is a standard error of prediction (SEP), as a statistical index on what is the difference between the measuring value and the virtual value, which may be obtained simultaneously with measuring. 
     In other words, the measuring line represents the correlation between the general absorption spectrum and the standard value obtained by measuring each component, e.g., Glucose, Albumin Nitrite and Bilirubin, of the sample, e.g., urine. One of the indexes representing an evaluation of the correlation is R̂2 and the other is a standard error of calibration (SEC) and Standard error of prediction (SEP). When the standard value and the spectrum value are represented by any straight line, R̂2, SEC and SEP represent the correlation between the standard value and the absorption spectrum according to how the data of two data is close to the certain straight line. 
     When it is most ideal, i.e., when the correlation between the standard value and the absorption spectrum is most good, R̂2 is 1 and SEC and SEP are close to 0 statistically. The relation between the standard value and the absorption spectrum may be represented using Multiple linear regression (MLR) and Regression of Partial Least Square (PLSR). 
     It measures a value of component contained in the sample, e.g., a value of Glucose using the measuring line. The value of component is expressed by a root mean of standard error prediction (RMSEP) value of reliability significance. The value of each component contained in the sample may be measured by measuring the component value within the reliability significance. 
       FIG. 27  is a graph showing spectrum results obtained by measuring Glucose in the urine using the urine component analyzing apparatus  700 .  FIG. 27  shows the measuring spectrum for Glucose having a concentration of 20%, 10%, 5% and 0.2%. After measuring water of a reference material at first, the absorption spectrum of Glucose for the reference material is expressed. The intensity of the spectrum is expressed as Absorbance unit (AU) of an absorptivity in a Y axis. The absorption spectrum measured by ATR-IR is expressed at about 0.01AU, and Glucose absorption spectrum may be confirmed between 900 and 1400 wavenumber of 4000 to 900 wavenumber which is measurement wavenumber region. As the concentration of Glucose is reduced by 0.2% for each stage starting from 20%, the absorption spectrum is reduced. 
       FIG. 28  is a graph showing spectrum results obtained by measuring Creatine in the urine using the urine component analyzing apparatus  700 .  FIG. 28  shows the measuring spectrum for Creatine having a concentration of 5%, 2% and 1%. The measuring spectrum is also an absorption spectrum which measures Creatine by using water as a reference material. The absorption spectrum measured by ATR-IR is expressed at about 0.008AU, and Creatine absorption spectrum may be confirmed between 1400 and 1900 wavenumber of 4000 to 900 wavenumber which is measurement wavenumber region. As the concentration of Glucose is reduced by 1% for each stage starting from 5%, the absorption spectrum is reduced. 
       FIG. 29  is a graph showing spectrum results obtained by measuring Urea in the urine using the urine component analyzing apparatus  700 .  FIG. 29  shows the measuring spectrum for Urea having a concentration of 10%, 5%, and 2%. The measuring spectrum is also an absorption spectrum which measures Urea by using water as a reference material. The absorption spectrum measured by ATR-IR is expressed at about 0.012AU, and Urea absorption spectrum may be confirmed between 1400 and 1900 wavenumber of 4000 to 900 wavenumber which is measurement wavenumber region. As the concentration of Glucose is reduced by 2% for each stage starting from 10%, the absorption spectrum is reduced. 
       FIG. 30  is a graph showing spectrum results obtained by measuring Cholesterol in the urine using the urine component analyzing apparatus  700 .

       FIG. 41  is a spectrum for standard Glucose sample measured using prior FT-IR and  FIG. 42  is a spectrum for standard Glucose sample measured using the urine analyzing apparatus  700 . The Glucose standard sample is melted into the third distilled water to prepare 100 mg/dL, 300 mg/dL, 500 mg/dL, 1000 mg/dL, before finding the spectrum. As shown in  FIG. 41  and  FIG. 42 , it will be appreciated that the spectrums of the standard Glucose sample using the prior FT-IR and the urine component analyzing apparatus  700  according to the present invention have a Glucose peak appeared at 950˜1150 cm−1 without a large difference between them. 
     Generally, since the prior IR equipment has the light source of low sensitivity, the measurement is performed using prior FT method. The prior FT method needs to deal with the data using Fourier transformation after dividing the ray of light source into two rays and making interference fringes by changing a length of a light path in one light ray periodically. At this time, since He—Ne laser needs to be used for making uniform the velocity of the moving mirror and making certain the position of the moving mirror to obtain reliable interference, it is very complex and big-sized so that it may not be attached on the toilet  710 . Meanwhile, the urine component analyzing apparatus  700  according to the present invention can exhibit the same effect as the prior art as shown in  FIG. 41  and  FIG. 42 , even though it is manufactured with low cost and small size.

As shown in  FIG. 43  and  FIG. 44 , a peak of protein is expressed at near 1600 cm−1 but a peak of Glucose is not overlapped, in the urine sample taken form the glycosuria patient. However, a basis line is slightly raised due to other different materials existing in the urine.
