Description

Urinal retrofit device that detects hematuria

A device capable of detecting hematuria, especially a modified urinal capable of detecting hematuria.

When a human being is normal and healthy, the urine should not be bloodshot. When a person's urine is bloodshot, or when a person passes bloody urine, it means that there is a health problem in the person's body. Specifically, those who emit hematuria may suffer from serious diseases such as endometrial cancer, bladder cancer, urinary tract stones, prostate cancer, and chronic kidney disease. Therefore, when a person's urine has blood streaks, the best situation is to immediately discover the occurrence of hematuria and treat and take care of the body as soon as possible. However, the appearance of hematuria may not necessarily be detected by the naked eye. When the concentration of capillaries in the urine is not high, the urine is likely not to appear obviously blood red. Therefore, today's interpretation of hematuria requires urine collection and further analysis of urine components.

One of the current indicators of hematuria is to observe whether oxyhemoglobin (also known as oxyhemoglobin; oxyhemoglobin) appears in a person's urine. When oxyhemoglobin appears in the urine, it is determined that hematuria is present situation. At present, there are two ways to analyze the presence of oxyhemoglobin in urine. One way is to collect the urine and send it to a medical institution. The institution will centrifuge the urine and observe the appearance of red blood cells under a microscope. Although this method is accurate and reliable, it is time-consuming and labor-intensive, so it is impossible to immediately inform the subject whether hematuria occurs.

Another method is to soak the test paper in the urine after collecting the urine, and use the color change of the test paper due to chemical changes to judge whether there is hematuria. However, this method is an unstable test method, because the quality of the test paper is easily oxidized and affected by moisture, which will affect the quality of the test, which will affect the test results of hematuria. Moreover, the subject must collect urine and soak it into the test paper by himself, which is inconvenient in operation, and the situation that the subject may touch the urine with his hands may cause hygienic troubles.

The above two existing methods for detecting hematuria have their own shortcomings, so it is hoped that a new invention can be used to detect hematuria to improve the above shortcomings.

In view of the above problems, the present invention provides a urinal retrofit device capable of detecting hematuria, which not only saves the subject from working hard to collect urine by himself, but also can detect hematuria in an instant and stably.

The urine to be tested remaining in the groove 21 is retained urine 1 , and the retained urine 1 is the part of the present invention that detects whether the urine to be tested is hematuria.

The measurement module 30 is disposed in the housing 10 , and the measurement module 30 further includes a first side 31 and a second side 32 opposite to each other. Wherein, the first side 31 has a light emitting unit 50 and a photosensitive unit 60 , and the light emitting unit 50 and the photosensitive unit 60 are respectively aligned with the second side 32 of the measurement module 30 . In addition, the end of the second side 32 of the measurement module 30 is provided with the transparent lens 33 . The light-transmitting lens 33 makes the end of the second side 32 of the measurement module 30 produce a sealing effect. The second side 32 of the measurement module 30 is disposed in the groove 21 of the flow channel 20 , so the transparent mirror 33 of the second side 32 is also disposed in the groove 21 . This means that when the retained urine 1 is loaded in the groove 21, the second side 32 will be immersed in the retained urine 1, and the transparent mirror 33 will prevent the retained urine 1 from flowing into the retained urine 1. In the measurement module 30.

The reflecting mirror 34 is arranged parallel to the transparent mirror 33 . The fixing frame 35 is hollow, so the retained urine 1 can flow in the fixing frame 35 , so that the retained urine 1 flows between the transparent mirror 33 and the reflecting mirror 34 .

The display unit 80 is disposed on the housing 10 , and the processing unit 40 is disposed in the housing 10 . The processing unit 40 is electrically connected to the display unit 80 and the measurement module 30 , the light emitting unit 50 and the photosensitive unit 60 disposed in the casing 10 respectively.

The light-emitting unit 50 is responsible for generating a detection light beam directed to the light-transmitting mirror 33 , and the light-sensing unit 60 is responsible for sensing the detection light beam. In other words, the processing unit 40 generates the detection beam through the light emitting unit 50 , and the processing unit 40 senses the detection beam through the photosensitive unit 60 . The detection beam is emitted from the transparent mirror 33 on the second side 32 into the retained urine 1 between the transparent mirror 33 and the reflective mirror 34 , and the detection beam further enters the reflective mirror 34 . After being reflected by the reflector 34, the detection beam passes through the retained urine 1 again and enters the transparent mirror 33 on the second side 32, and then enters the first side 31 through the transparent mirror 33. In the photosensitive unit 60, the photosensitive unit 60 generates a sensing signal after receiving the detection light beam. The photosensitive unit 60 sends the sensing signal to the processing unit 40 , and when the processing unit 40 receives the sensing signal, the processing unit 40 generates a detection result signal according to the sensing signal. The processing unit 40 sends the test result signal to the display unit 80, so that the display unit 80 displays the test result of the urine to be tested according to the test result signal. Wherein, the light path of the detection beam generated by the light emitting unit 50 will not touch the photosensitive unit 60 before it touches the reflector 34, that is to say, the photosensitive unit 60 will not block the detection beam to detect the retained urine 1 light path.

In an embodiment of the present invention, the processing unit 40 further stores a detection spectrum data and a light signal information. After the photosensitive unit 60 generates the sensing signal, the photosensitive unit 60 sends the sensing signal to the processing unit 40, and the processing unit 40 analyzes a spectral information of the sensing signal, and the processing unit 40 Information and the detection spectrum data generate a detection result data.

Test results. Wherein, the detection spectrum data stored in the processing unit 40 is a background absorption spectrum data before the detection beam detects hematuria. That is to say, the collection spectrum information of the hematuria does not appear in the detection spectrum data.

Please refer to Fig. 2 to Fig. 11 comprehensively, in this embodiment, the display unit 80 further includes a result display light 81, a low battery light 82 and a sensory wake-up light 83, and the result display light 81, the low Each of the battery light 82 and the sensor wake-up light 83 is a light-emitting diode (LED). The result display lamp 81 displays light signals of at least two colors according to the test result signal to display the test result of the urine to be tested 1 . In addition, the present invention further includes a power unit 70 . The power unit 70 is electrically connected to the processing unit 40 to provide power.

The processing unit 40 further stores a built-in data, and the built-in data includes a thermistor threshold and a low battery threshold. When the processing unit 40 detects that a remaining power of the power unit 70 is less than the low battery threshold, the processing unit 40 generates a low battery signal, and the processing unit 40 sends the low battery signal to the display unit 80, so that the The low battery light 82 of the display unit 80 lights up a red light. The red light signal can generate a warning effect to attract the attention of the user of the urinal retrofit device capable of detecting hematuria, prompting the user to replenish the power of the power unit 70 .

The processing unit 40 is further electrically connected to a thermal unit 90 . The thermal unit 90 includes a thermistor, and the thermal unit 90 is disposed in the flow channel 20 . Wherein, the thermistor is a negative temperature coefficient thermistor (Negative Temperature Coefficient thermistor; NTC thermistor), and the thermistor generates a thermal signal to the processing unit 40 . The characteristic of the negative temperature coefficient thermistor is that when the temperature is lower, the resistance value of the negative temperature coefficient thermistor is larger, and when the temperature is greater, the resistance value of the negative temperature coefficient thermistor will become Small, at a fixed voltage to facilitate more current flow.

When the urine to be tested flows into the flow channel 20 from the inlet opening 14 , the thermistor reduces the resistance value of the NTC thermistor due to the heat of the urine to be tested. On the contrary, when the urine to be tested has not yet appeared, the temperature of the thermistor is low, and the resistance value of the negative temperature coefficient thermistor is relatively large, and in this case, the processing unit 40 is in a standby mode to reduce power consumption. In the standby mode, the processing unit 40 has not activated the light emitting unit 50 to generate the detection beam, and has not activated the photosensitive unit 60 to sense the detection beam.

In the middle of the second plane and the first plane, the aforementioned emitting light channel 301 and the at least one reflecting light channel 302 are disposed. The normal direction of the first plane is a first direction, and the first direction is the travel direction of the detection light beam. The emitting light channel 301 is disposed at the center of the measurement module 30 , and the center refers to the center of the section of the first plane and the center of the section of the second plane. The outgoing light channel 301 is disposed between the center of the cross-section of the first plane and the center of the cross-section of the second plane, and guides the detection beam to travel along the first direction. The at least one reflective light channel 302 is arranged on an outer side of the outgoing light channel 301, and a first distance between the at least one reflective light channel 302 and the outgoing light channel 301 on the first side is greater than the at least one reflected light channel A second distance between the channel 302 and the outgoing light channel 301 on the second side.

Please refer to FIG. 16 , which is a schematic diagram of blood absorption spectrum. The schematic diagram of blood absorption spectrum presents the molar extinction coefficient (molar extinction coefficient) of oxyhemoglobin (also known as oxyhemoglobin; oxyhemoglobin) in the spectrum of different wavelengths (wavelength). When the present invention detects whether the urine to be tested is hematuria, the present invention analyzes whether the oxyhemoglobin appears in the urine to be tested, because human blood contains a large amount of oxyhemoglobin. When the Mole extinction coefficient is larger, it means that the light of this wavelength will be easily absorbed, and on the contrary, when the Mole extinction coefficient is smaller, it means that the light of this wavelength will be easily prevented from being absorbed. Taking Figure 14 as an example, the visible wavelength is between about 400 nanometers (nanometer; nm) and 500 nm, and at about 410 nm, the molar extinction coefficient of the oxyhemoglobin is the largest, while the wavelength is between about 600 nm and 800 nm, At about 690 nm, the molar extinction coefficient of the oxyhemoglobin is the smallest. In fact, the place of 690 nm is equivalent to the wavelength of red light in visible light, and the place of 410 nm is equivalent to the wavelength of violet light in visible light. From the above, it can be explained that the oxyhemoglobin is most likely to absorb purple light, and the oxyhemoglobin is least likely to absorb red light, so when the oxyhemoglobin does not absorb but reflects red light, the color of human blood is red . The above is the spectral absorption characteristic of the blood absorption spectrum.

The processing unit 40 of the present invention compares the spectral information with the detection spectral data, if the spectral information is similar to the absorption spectrum of the detection spectral data, and the spectral information does not show that purple light is absorbed in a large amount at 410 nm and red does not appear If light at 690 nm is largely reflected but not absorbed, the processing unit 40 determines that the urine to be tested is not hematuria. On the contrary, if the absorption spectra of the spectral information and the detection spectral data are different, and the spectral information shows that purple light is largely absorbed at 410 nm and that red light is largely reflected and not absorbed at 690 nm, then the processing unit 40 determines that the The urine to be tested was hematuria.

In this another embodiment, although the absorption spectrum of water does not appear in the visible light band, so the water looks transparent, but the water will affect the concentration of the urine to be tested, so it will affect the spectrum obtained by the processing unit 40 The information corresponds to the magnitude of the Mole extinction coefficient. That is to say, the greater the concentration of the urine to be tested, the greater the corresponding molar extinction coefficient in the spectral information, and vice versa. Therefore, the processing unit 40 still has a way to know whether the water in the urine to be tested is sufficient, so as to infer whether the subject is not drinking enough water.
