[0040] Such as Figures 1 to 6As shown in the figure, some embodiments of the present application provide a urine analyzer, including a sample aspiration device 1, a sample transport pipeline 2, and a urine color, turbidity, specific gravity, and conductivity detection device 3. The sample aspiration device 1 is used to aspirate the sample, and the sample transport pipeline 2 is used to transport the sample.

[0041] The urine color, turbidity, specific gravity, and conductivity detection device 3 includes a housing 31, a prism module 32, a turbidity detection module 33, a specific gravity detection module 34, a color detection module 35, and a conductivity detection module 36. Among them, the prism module 32 is installed inside the housing 31 and is provided with a sample channel for the sample to pass through. The turbidity detection module 33, the specific gravity detection module 34, and the color detection module 35 are all installed on the prism module 32 and are arranged circumferentially around the sample channel. The conductivity detection module 36 is also installed on the prism module 32 and is located at the end of the sample channel. After the sample fills the sample channel, the turbidity detection module 33, the specific gravity detection module 34, the color detection module 35, and the conductivity detection module 36 respectively complete the detection of the turbidity, specific gravity, color, and conductivity of the sample, effectively reducing the required amount of the sample and facilitating the improvement of the detection efficiency.

[0042] Both ends of the sample transport pipeline 2 are respectively connected to the sample aspiration device 1 and the sample channel to transport the sample aspirated by the sample aspiration device 1 into the sample channel, reducing the flow path of the sample and facilitating the reduction of the sample usage.

[0043] It should be noted that the sample aspiration device 1 can be set as a sampling needle to aspirate the sample.

[0044] Exemplarily, the sample is set as urine.

[0045] In some embodiments, a circuit board 37 is installed on the housing 31, and the circuit board 37 is electrically connected to the turbidity detection module 33, the specific gravity detection module 34, the color detection module 35, and the conductivity detection module 36 respectively. After each detection module detects the sample, the obtained information is transmitted to the circuit board 37, and the detection result is obtained after analysis by the circuit board 37.

[0046] In some embodiments, the prism module 32 includes a prism 321 and prism covers 322. There are two prism covers 322, which are respectively located at both ends of the prism 321. A through first flow channel 3211 is provided inside the prism 321, and a through second flow channel 3221 is provided inside the prism cover 322. The first flow channel 3211 and the second flow channel 3221 are connected to form a sample channel.

[0047] Exemplarily, the prism 321 is set as a quadrangular prism, and the four side walls of the quadrangular prism have the same thickness.

[0048] It should be noted that the prism module 32 further includes a prism base 323. The prism 321 is installed inside the prism base 323, and the prism cover 322 is installed at both ends of the prism base 323. The prism module 32 is connected to the housing 31 through the prism base 323, and the turbidity detection module 33, the specific gravity detection module 34, and the color detection module 35 are all installed on the prism base 323, and the conductivity detection module 36 is installed on the prism cover 322.

[0049] Exemplarily, the prism base 323 can be set to be spliced by two or more separable structures to facilitate the installation of the prism 321.

[0050] In some embodiments, the conductivity detection module 36 is installed at both ends of the sample channel and includes a conductivity electrode 361 and a pressing member 362, that is, the conductivity electrodes 361 are pressed on the prism covers 322 at both ends of the prism 321 through the pressing member 362. When the sample fills the sample channel, a preset pulse voltage is applied between the two conductivity electrodes 361, and the conductance between the two conductivity electrodes 361 is measured to obtain the conductance value of the sample.

[0051] Exemplarily, the prism base 323 can be threadedly connected to the pressing member 362, and the conductivity electrode 361 is clamped between the prism cover 322 and the pressing member 362. The pressing member 362 is made of a non-insulating material such as metal.

[0052] It should be noted that the conductivity detection module 36 further includes a temperature sensor 363. A liquid path tube 38 is connected to the inlet end of the sample channel, and the sample flows into the sample channel from the sample transport pipeline through the liquid path tube 38. The temperature sensor 363 is pressed on the liquid path tube 38 to detect the temperature of the sample in the liquid path tube 38. The sample temperature detected by the temperature sensor 363 is used to correct the obtained sample conductance value to obtain the conductivity of the sample.

[0053] Specifically, the liquid path tube 38 is installed on the housing 31 through a fixing member 364, and the temperature sensor 363 is also installed on the fixing member 364 and pressed on the liquid path tube 38.

[0054] Exemplarily, the temperature sensor 363 can be set as a temperature acquisition board.

[0055] It should be noted that the liquid path tube 38 is connected to the sample channel through the pressing member 362, and the other pressing member 362 away from the liquid path tube 38 can also be connected with a pipeline for the sample in the sample channel to flow out.

[0056] In some embodiments, the specific gravity detection module 34 includes a specific gravity emission light source 341 and a light source detector 342. The light source detector 342 is located between the specific gravity emission light source 341 and the prism 321, and real-time monitors the change in the energy light intensity of the light beam emitted by the specific gravity emission light source 341 to determine whether the light beam meets the test requirements, thereby ensuring the accuracy of the sample specific gravity detection.

[0057] It should be noted that a trapezoidal boss 3212 is provided on the first outer side wall of the prism 321. The specific gravity detection module 34 further includes a specific gravity detection sensor 343. The specific gravity emission light source 341 and the specific gravity detection sensor 343 are respectively located on both sides of the waist of the trapezoidal boss 3212. Moreover, the waist side surface of the trapezoidal boss 3212 corresponding to the specific gravity emission light source 341 is coated with optical black paint, and an incident port 3213 through which the light beam emitted by the specific gravity emission light source 341 passes is provided. The incident port 3213 is the area on the waist side surface of the trapezoidal boss 3212 where no optical black paint is coated.

[0058] The light beam emitted by the specific gravity emission light source 341 enters the prism 321 of the trapezoidal boss 3212 through the incident port 3213 and is transmitted to the inner side wall corresponding to the first outer side wall of the prism 321 to form a collimated light beam for irradiation on the inner side wall. When the sample channel is stably filled with the sample, part of the light beam undergoes total internal reflection on the inner side wall, enters the prism 321 of the trapezoidal boss 3212 again, and exits from the waist side surface of the trapezoidal boss 3212 and is received by the specific gravity detection sensor 343, thereby completing the sample specific gravity detection. Since the specific gravity refractive indices of different samples are different, the critical angles of total internal reflection are different. Therefore, the light beam does not need to pass through the sample, which reduces the absorption or attenuation of the light beam by the sample, thereby improving the accuracy of detecting special samples such as severely turbid or dark-colored samples.

[0059] Exemplarily, the specific gravity detection sensor 343 can be set as a photodiode.

[0060] Specifically, the specific gravity detection module 34 further includes a diaphragm 344, and the diaphragm 344 is located between the prism 321 and the specific gravity detection sensor 343. After part of the light beam emitted by the specific gravity emission light source 341 undergoes total internal reflection, it is first blocked by the diaphragm 344 to block stray light and then received by the specific gravity detection sensor 343.

[0061] Exemplarily, the specific gravity detection module 34 further includes a specific gravity cover 345, and the specific gravity cover 345 is installed on the prism seat 323. Moreover, the specific gravity emission light source 341, the light source detector 342, the specific gravity detection sensor 343, and the diaphragm 344 are all installed on the specific gravity cover 345.

[0062] In some embodiments, the turbidity detection module 33 includes a turbidity emission light source 331 and a turbidity detection sensor 332. The turbidity emission light source 331 and the turbidity detection sensor 332 are vertically arranged and are respectively arranged opposite to the sample channel. The light beam emitted by the turbidity emission light source 31 is transmitted to the sample through the prism 321. Since the sample itself suspends particles, the light beam scattered by the sample is received by the turbidity detection sensor 332, thereby completing the turbidity detection of the sample.

[0063] Specifically, the turbidity detection sensor 332 can be arranged opposite to the second outer side wall of the prism 321, and the turbidity emission light source 331 can be arranged opposite to the third outer side wall of the prism 321. The second outer side wall and the third outer side wall of the prism 321 are adjacent and perpendicular to each other, and the third outer side wall is arranged opposite to the first outer side wall.

[0064] Exemplarily, the turbidity detection sensor 332 can be set as a photodiode.

[0065] Exemplarily, both the turbidity emission light source 331 and the turbidity detection sensor 332 are mounted on the prism base 323.

[0066] In some embodiments, the color detection module 35 includes a color emission light source 351 and a color detection sensor 352. The color emission light source 351 and the color detection sensor 352 are located on the same side of the sample channel. A reflective film is arranged on the side wall of the sample channel. The color emission light source 351 and the color detection sensor 352 are arranged corresponding to the reflective film. The light beam emitted by the color emission light source 351 is transmitted to the sample through the prism 321, and then reflected by the reflective film and received by the color detection sensor 352, completing the color detection of the sample.

[0067] Specifically, the reflective film is arranged on the fourth outer side wall of the prism 321, and the fourth outer side wall of the prism 321 is arranged opposite to the second outer side wall. The color emission light source 351 and the color detection sensor 352 are on the same side as the turbidity detection sensor 332 and are also arranged opposite to the second outer side wall of the prism 321. Moreover, both the color emission light source 351 and the color detection sensor 352 are welded to the color acquisition board 353, and the color acquisition board 353 is mounted on the prism base 323.

[0068] In some embodiments, the sample flowing out of the sample channel flows into the flow cell 4 for discharging the sample.

[0069] In summary, a urine analyzer provided by the present utility model has a sample channel provided on a prism module. After the sample fills the sample channel, a turbidity detection module, a specific gravity detection module, and a color detection module located circumferentially of the sample channel, as well as a conductivity detection module located at the end of the sample channel, can simultaneously complete the detection of the color, turbidity, specific gravity, and conductivity of the sample, effectively reducing the required amount of the sample, and there is no need to inject the sample multiple times, which is also conducive to improving the detection efficiency; moreover, the sample sucked by the sample suction device directly flows into the sample channel through the sample transport pipeline, which is conducive to reducing the amount of the sample.

[0070] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
