Description

Technical Field

[0001] This invention relates to the field of urine detection and analysis technology, and in particular to a urine staining and cleaning device. Background Technology

[0002] Urine formed element examination refers to the detection of casts and various pathologically significant particles in urine, such as red blood cells, white blood cells, renal epithelial cells, and bacteria. It is an indispensable and important component of complete urine analysis, and is significant for the diagnosis, localization, differential diagnosis, prognosis, drug treatment monitoring, and health screening of urinary system diseases. Staining urine formed elements can prevent missed and false detections during the testing process, and allows for clear observation of the fine structure of formed elements within a short period after staining.

[0003] In conventional urine staining analysis devices, the probe first drips the sample into the staining chamber, then cleans it in a moving washing tank to prepare for the next step. Since the staining chamber and washing tank are independent devices, the probe may drip during movement, potentially contaminating the instrument and increasing uncontrollable risks. Furthermore, the staining chamber is typically a single unit, which cannot meet the requirements of high-speed measurement.

[0004] Based on the above-mentioned technical problems, those skilled in the art urgently need to develop a urine staining and cleaning device with a compact structure that can effectively solve the problems of instrument contamination and speed measurement. Summary of the Invention

[0009] Furthermore, the heating mechanism includes a heating belt to heat the staining chamber; A temperature sensor detects the temperature of the staining chamber; And an overheat protection device, which controls the heating belt to stop heating when the temperature exceeds the threshold range.

[0010] Furthermore, the staining chamber has an overflow trough and a reaction trough, with the overflow trough located above the reaction trough.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0019] See Figures 1-3 As shown; The present invention provides a urine staining cleaning device, the cleaning device comprising: The staining pool 1 has a staining chamber 101 inside, and a staining hole 102 is opened at the top for the probe 5 to be inserted into the staining chamber 101. The bottom of the staining chamber 101 drains liquid. The side wall of the staining chamber 101 is provided with a staining solution inlet 103 and a reaction solution suction port 104. The staining solution inlet 103 is located above the reaction solution suction port 104. The cleaning tank 2 is installed integrally with or adjacent to the staining tank 1, and a cleaning cavity 201 is formed inside the cleaning tank 2. A cleaning hole 202 is opened at the top for the probe 5 to be inserted into the cleaning cavity 201. The bottom of the cleaning cavity 201 drains liquid, and a cleaning liquid filling port 203 is provided on the side wall of the cleaning cavity 201. The cleaning device also includes: A heating mechanism 3 is provided on the side wall of the staining chamber 101 for heating the staining chamber 101; And a float detection device 4 is installed in the cleaning chamber 201 to detect the volume of liquid inside the cleaning chamber. When the float rises, the instrument alarms "cleaning tank is full".

[0020] As a further description of this embodiment, the bottom of the staining chamber 101 is provided with a first waste liquid outlet 105, and a first waste liquid valve is provided below the first waste liquid outlet 105 to control the opening and closing of the first waste liquid outlet 105. The bottom of the cleaning chamber 201 is provided with a second waste liquid outlet 204, and a second waste liquid valve is provided below the second waste liquid outlet 204 to control the opening and closing of the second waste liquid outlet 204.

[0021] As a further description of this embodiment, the cleaning chamber 201 includes a first chamber 2011 and a second chamber 2012 that are interconnected. The probe 5 performs cleaning in the first chamber 2011, and the float detection device 4 is disposed in the second chamber 2012. The first cavity 2011 and the second cavity 2012 are respectively provided with a first cavity waste liquid outlet and a second cavity waste liquid outlet. The first cavity waste liquid outlet and the second cavity waste liquid outlet are connected in the liquid path and are simultaneously controlled by the second waste liquid valve (if they are in one cavity, the float may rise directly when cleaning fluid is added, causing a false alarm).

[0022] As a further description of this embodiment, the heating mechanism 3 includes a heating band 301 for heating the staining chamber 101; Temperature sensor 302 detects the temperature of the staining chamber 101; And an overheat protection device 303, which controls the heating belt 301 to stop heating when the temperature exceeds the threshold range.

[0023] As a further description of this embodiment, the staining chamber 101 has an overflow groove 1011 and a reaction groove 1012. The overflow groove 1011 is disposed above the reaction groove 1012. The heating mechanism 3, the staining solution filling port 103 and the reaction solution sampling port 104 are all installed on the side wall corresponding to the part of the reaction groove 1012.

[0024] As a further description of this embodiment, the overflow tank is equipped with a liquid level electrode 6 for detecting the liquid level height in the overflow tank 1011.

[0025] As a preferred technical solution in this embodiment, the staining pool 1 can be one or more with the same structure.

[0026] As a preferred technical solution in this embodiment, the size of the reaction tank 1012 gradually decreases from the part near the overflow tank 1011 to the bottom wall (to reduce the amount of back dead space when the reaction liquid is sucked out).

[0027] During operation, probe 5 draws a urine sample and injects it into the staining chamber 101. The staining solution is then injected into the staining chamber 101 through the staining solution injection port 103. The heating mechanism 3 heats the sample for a period of time to incubate it with the staining solution, forming a reaction solution. The reaction solution is then drawn out through the reaction solution suction port 104 into the reaction apparatus for detection.

[0028] Sample staining function: Due to the high testing speed, actual testing requires alternating switching between two staining tanks. The dual-station staining tanks also have a liquid level detection function. When the waste liquid generated during staining tank cleaning exceeds the discharged waste liquid, the liquid level in the staining chamber will gradually rise. When the liquid level touches the liquid level electrode 6, the instrument alarms "Staining tank full." Manual troubleshooting is required. Simultaneously, staining tank 1 also has a heating belt 301 to heat the staining chamber 101. An internal temperature sensor 302 and overheat protector 303 implement closed-loop heating control to achieve a constant temperature staining environment of 37°C ± 1°C.

[0029] After the sample is dispensed, probe 5 is moved to cleaning tank 2 for probe cleaning.

[0030] Cleaning needle outer wall function: Cleaning fluid is injected from the cleaning fluid inlet 203 at a certain speed. After passing through the internal diversion module, the cleaning fluid is used to rinse the needle outer wall from four directions. A cleaning water film is formed at the outlet end, accompanied by the lifting action of probe 5, thus completing the outer wall cleaning process. If the waste liquid generated during the waste discharge process is greater than the waste liquid discharged, the liquid level in the cleaning chamber 201 will gradually rise, lifting the internal float, and the instrument will alarm "Cleaning tank full".

[0031] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
