[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides a urine analyzer with the following advantages: 1. This urine analyzer, through the design of an optical detection unit, a rotating shaft, and test strip inserts capable of holding multiple urine test strips, allows multiple urine test strips to be placed near the optical detection unit in turn by rotating the shaft. This enables batch testing of multiple urine test strips, reducing the time spent placing and removing test strips and effectively improving testing efficiency. Furthermore, because the test strip inserts are detachable from the rotating shaft, they can be removed before inserting the urine test strips. This allows for direct confirmation of proper placement of the urine test strips. After use, the test strip inserts can be easily disassembled and cleaned, effectively preventing residual contaminants from affecting subsequent use and further ensuring the accuracy of the test results.
[0018] 2. This urine analyzer, by setting perforations, fin grooves, positioning fins, embedded grooves, limiting grooves, nuts, and screws, can easily achieve quick assembly and disassembly of the rotating shaft and test strip insert. Simply insert the rotating shaft into the perforation of the test strip insert, insert the positioning fins into the corresponding fin grooves, and then tighten the nuts and screws to securely fix the test strip insert.
[0019] 3. This urine analyzer, by setting up a positioning block, a reflector, and an infrared sensor, utilizes the working principle that the light emitted by the infrared sensor is reflected back onto the infrared sensor by the reflector. This allows it to accurately determine whether the urine test strip on the test strip insert is aligned with the optical detection unit, thereby achieving precise positioning of the test strip insert. When the rotating shaft drives the test strip insert to the detection position, the optical detection unit can accurately capture the urine test strip in the facing direction, effectively avoiding deviations in test results caused by viewing angle bias.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please see Figure 1 - Figure 6 This utility model provides a urine analyzer, including a body 1 and an optical detection unit 2. The optical detection unit 2 is fixedly installed inside the body 1. A rotating shaft 3 is rotatably arranged inside the body 1. A test strip insert 4 is detachably arranged on the rotating shaft 3. A through hole 41 is opened in the center of the shaft of the test strip insert 4, and a fin groove 42 is opened at one end of the test strip insert 4. The fin groove 42 communicates with the through hole 41. Positioning fins 31 are arranged on both sides of the rotating shaft 3, and the rotating shaft 3 is inserted into the through hole 41, and the positioning fins 31 are inserted into the fin groove 42. Multiple urine test strips can be placed in a ring array on the outer side of the test strip insert 4. When the rotating shaft 3 rotates, the urine test strips placed at different positions on the outer side of the test strip insert 4 can be moved in turn to the detection area of the optical detection unit 2 for detection. The machine body 1 is equipped with a display 11 and an inspection form outlet 12.
[0025] As can be seen from the above, by setting up the optical detection unit 2, the rotating shaft 3, and the test strip insert 4 that can accommodate multiple urine test strips, the rotation of the rotating shaft 3 allows multiple urine test strips to be brought close to the optical detection unit 2 in turn, thereby enabling batch testing of multiple urine test strips, reducing the time spent placing and removing urine test strips, and effectively improving testing efficiency. Simultaneously, since the test strip insert 4 is detachable from the rotating shaft 3, the test strip insert 4 can be removed from the rotating shaft 3 before inserting the urine test strip. Therefore, it is possible to visually confirm whether the urine test strip is properly placed. After use, the test strip insert 4 can also be easily disassembled and cleaned, effectively preventing residual contaminants from the urine test strip from affecting the subsequent use of the test strip insert 4, further ensuring... To ensure the accuracy of test results, in this application, since the test strip insert 4 is quick-release, it is more convenient to remove the test strip insert 4 from the rotating shaft 3 and then insert the urine test strip than to insert the urine test strip into the test strip insert 4 fixed on the rotating shaft 3. This avoids the situation where the urine test strip is not inserted properly or is squeezed and deformed. At the same time, when a large number of urine test strips can be inserted into the test strip insert 4 (for example, more than 8 urine test strips), the time spent removing the test strip insert 4 from the rotating shaft 3 and then inserting the urine test strip and testing all the urine test strips on the test strip insert 4 is shorter than the time spent inserting the same number of urine test strips into the same test strip holder and testing them sequentially.
[0026] When using this device, first place the urine test strips in a circular array on the outer side of the test strip insert 4, then fit the test strip insert 4 onto the rotating shaft 3 through the perforation 41, ensuring that the positioning fin 31 is accurately inserted into the fin groove 42. After starting the device, the rotating shaft 3 drives the test strip insert 4 to rotate, so that multiple urine test strips enter the detection area of the optical detection unit 2 in turn. After the detection is completed, the real-time results can be viewed on the display 11, or a paper test report can be obtained through the test report outlet 12. Furthermore, when testing the urine test strips, other urine test strips to be tested can be placed on another empty test strip insert 4 in advance. When the urine test strip on the test strip insert 4 being tested has completed the test and the test strip insert 4 has been removed, the other test strip insert 4 with the urine test strips already placed on it can be installed on the rotating shaft 3 for testing. Only two test strip inserts 4 are needed to greatly improve the detection speed.
[0027] Example 2
[0028] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the difference between this embodiment and the above embodiment is that the test strip insert 4 is provided with a test strip slot 5, and the outer side of the test strip insert 4 is provided with a shooting port 51 that penetrates into the test strip slot 5. The end of the test strip slot 5 is provided with an expansion port 52.
[0029] As can be seen from the above, by setting the expansion port 52, it is easy to insert the urine test strip into the test strip slot 5, and the test strip is avoided from shifting or being damaged during the insertion process. By setting the imaging port 51, the optical detection unit 2 can directly detect the urine test strip in the test strip slot 5, and it is also easy for the human eye to observe whether the urine test strip is inserted in place.
[0030] The other end of the test strip insert 4 has an embedded groove 43, and a limiting groove 44 is provided on the embedded groove 43. A nut 45 is movably fitted inside the limiting groove 44. A screw 32 is fixedly installed at the end of the rotating shaft 3, and the screw 32 is threadedly matched with the nut 45.
[0031] As can be seen from the above, by setting the nut 45 and screw 32, and with the help of the positioning wing 31, when the nut 45 and screw 32 are tightened, the test paper insert 4 can be fixed on the rotating shaft 3. By setting the inner groove 43 and the limiting groove 44, when the nut 45 and screw 32 are tightened, the nut 45 can be completely inside the inner groove 43, and the setting of the inner groove 43 can provide space for the finger to rotate the nut 45.
[0032] A stop block 46 is symmetrically fixedly installed at the end of the limiting groove 44, and a retaining ring 47 is fixedly installed at the open end of the nut 45. The retaining ring 47 fits against the inner wall of the limiting groove 44.
[0033] As can be seen from the above, by setting the stop block 46 and the retaining ring 47, the nut 45 cannot be dislodged from the limiting groove 44, thus preventing the nut 45 from falling off. At the same time, since the retaining ring 47 is in contact with the inner wall of the limiting groove 44, when the test paper insert 4 is inserted into the rotating shaft 3, the nut 45 and the screw 32 are directly aligned.
[0034] Example 3
[0035] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the difference between this embodiment and the above embodiment is that a dirt cover 6 is also fixedly installed inside the body 1. An observation port 61 is opened at the upper end of the dirt cover 6. The observation port 61 is arranged opposite to the optical detection unit 2. Ball bearings 62 are installed on the inner walls at both ends of the dirt cover 6. The ball bearings 62 are arranged in a ring array and are in contact with the outer wall of the test strip insertion post 4. The rotating shaft 3 is rotatably installed inside the dirt cover 6.
[0036] As can be seen from the above, the anti-fouling cover 6 can prevent the urine sample on the urine test strip from passing through the anti-fouling cover 6 and falling into the body 1. The observation port 61 is used to ensure that the detection light path of the optical detection unit 2 is not blocked. The ball bearing 62 can support the test strip insert 4 without affecting the rotation of the test strip insert 4, and reduce the shaking during the rotation process.
[0037] A positioning block 7 is fixedly installed at the end of the rotating shaft 3 away from the test strip insertion post 4. A reflector 71 is provided on the positioning block 7. An infrared sensor 72 is fixedly installed inside the body 1. The infrared sensor 72 is adapted to the reflector 71.
[0038] As can be seen from the above, the reflector 71 on the positioning block 7 works in conjunction with the infrared sensor 72 inside the body 1. By emitting light through the infrared sensor 72 and reflecting light through the reflector 71, the rotation position of the rotating shaft 3 and the test strip insertion post 4 can be accurately identified, ensuring that the urine test strip on the test strip insertion post 4 can be accurately aligned with the optical detection unit 2 after each rotation, thus avoiding detection deviation due to positional shift.
[0039] A drive motor 8 is fixedly installed inside the body 1, and the drive end of the drive motor 8 is connected to the rotating shaft 3 through gear transmission.
[0040] As can be seen from the above, the drive motor 8 provides stable power to the rotating shaft 3 through gear transmission. In this embodiment, both the drive motor 8 and the infrared sensor 72 are electrically connected to the PLC controller of the machine body 1, so that the drive end of the drive motor 8 can adjust the rotation angle according to the signal of the infrared sensor 72.
[0041] A placement rack 9 is provided on one side of the machine body 1, and the placement rack 9 has an insertion port for placing the test paper insertion post 4.
[0042] As can be seen from the above, the slots on the rack 9 can be used specifically to store spare test strip inserts 4, or to temporarily place test strip inserts 4 that need to be cleaned after use, so as to avoid the test strip inserts 4 being placed randomly and thus causing contamination or damage, while also making it convenient for operators to quickly take them out.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
