Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a detection device and a urine analyzer. Background Technology

[0002] Urine analyzers are core equipment in medical laboratories for automated urine testing, playing a crucial role in the auxiliary diagnosis of urinary system diseases, metabolic diseases, and infections. They accurately detect the chemical composition of urine, providing clinicians with key diagnostic information and aiding in early disease detection and treatment.

[0003] When testing samples, the counting chamber and microscope are key components. The counting chamber consists of a base plate and a cover plate, with the gap between them forming the observation area for the sample and reagent mixture to flow. The testing procedure is as follows: first, the sample is thoroughly mixed with a specific reagent, and then added dropwise to the observation area of ​​the counting chamber; subsequently, the counting chamber is placed at the corresponding testing position on the urine analyzer, and the high-magnification function of the microscope is used to observe and analyze the formed elements such as cells, casts, and crystals in the mixture to obtain key urine indicator information.

[0004] However, the flow time and direction of different sample and reagent mixtures vary in the observation area, which can easily make it difficult for the microscope to obtain complete and clear images of the mixture, thus seriously affecting the accuracy of the test results. To overcome this problem, the usual approach is to improve the structure of the counting chamber, hoping to make the flow of the mixture in the observation area more uniform and stable, and minimize image distortion caused by abnormal flow. However, improving the counting chamber structure faces the practical bottleneck of manufacturing precision. Achieving high-precision structural improvements often requires advanced processing equipment and sophisticated techniques, which undoubtedly increases the manufacturing cost of the counting chamber significantly, placing a certain economic burden on practical applications.

[0033] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0034] Please see Figure 1-4 This utility model provides a detection device, including: a fixed bracket 1 and a detection platform 2, a microscope 3, a supplementary light element 4, a counting plate limiting mechanism 5, a first moving mechanism 6, and a second moving mechanism 7, all mounted on the fixed bracket 1. The microscope 3 is located above the detection platform 2, and the supplementary light element 4, which can be an LED light or similar structure, is located below the detection platform 2. The detection platform 2 is provided with a first through hole 21 for the light from the supplementary light element 4 to pass through. The center lines of the microscope 3 and the supplementary light element 4 coincide with the central axis of the first through hole 21. Here, the coincidence of the center lines of the microscope 3 and the supplementary light element 4 with the central axis of the through hole means that the center line of the image acquired by the microscope 3 and the center line of the light beam emitted by the supplementary light element 4 coincide with the center line of the first through hole 21, ensuring that the microscope 3 can acquire a clear image.

[0035] The first moving mechanism 6 is mounted on the second moving mechanism 7, which drives the first moving mechanism 6 to move along the first direction a and its opposite direction. The counting plate limiting mechanism 5 is mounted on the first moving mechanism 6 and connects to the counting plate 9 to restrict its movement along the third direction b. The first moving mechanism 6 drives the counting plate 9, fixed to the counting plate limiting mechanism 5, to move on the detection platform 2 along the second direction b and its opposite direction. The first direction a, the second direction b, and the third direction b are arranged perpendicularly to each other. Figure 1 As shown, the first direction a is Figure 1 The direction from front to back in the middle, the second direction b is Figure 1 In the left-to-right direction, the third direction c is Figure 1 The direction from bottom to top in the middle.

[0036] In use, the lower side of the counting plate 9 abuts against the upper side of the detection platform 2 to restrict the counting plate 9 from moving in the opposite direction of the third direction. Then, a counting plate limiting mechanism 5 is connected to the counting plate 9 to restrict the counting plate 9 from moving in the third direction c. Then, under the action of the second moving mechanism 7, the counting plate 9 is driven to move in the first direction a and its opposite direction, and under the action of the first moving mechanism 6, the counting plate 9 is driven to move in the second direction b and its opposite direction, that is, the counting plate 9 slides on the upper surface of the detection platform 2, so that different positions of the observation area of ​​the counting plate 9 correspond to the central axis of the first through hole 21, thereby ensuring that the microscope 3 can obtain a complete and clear image of the mixture and ensuring the accuracy of the detection results.

When the counting plate 9 is fixed, the second fixing member 52 is subjected to force, causing the second fixing member 52 to slide on the guide post 531, thereby compressing the elastic member, so as to open the opening of the counting plate limiting groove 511 by the second fixing member 52. After the counting plate 9 is placed into the counting plate limiting groove 511, the second fixing member 52, under the reset action of the elastic member, closes the opening of the counting plate limiting groove 511, thereby fixing the counting plate 9 within the counting plate limiting groove 511. In this embodiment, the elastic member is a spring.

The first driving member 62 and the first guide member 64 are disposed on the first fixed base 61, and the first fixed member 51 is slidably connected to the first guide member 64. The first driving member 62 drives the first fixed member 51 to move along the second direction b and the opposite direction on the first guide member 64 through the first transmission assembly 63. Specifically, the first driving member 62 can be a motor, and the first guide member 64 can be a guide rod. The first transmission assembly 63 includes a first lead screw 631 and a first lead screw nut 632. The first lead screw 631 is coaxially disposed on the output shaft of the first driving member 62, and its end away from the first driving member 62 is rotatably connected to the first fixed base 61. The first lead screw nut 632 is disposed on the first lead screw 631 and is slidably connected to the first guide member 64. The first fixed member 51 is connected to the first lead screw nut 632.

[0041] The second moving mechanism 7 includes a second driving member 71, a second transmission assembly 72, and a second guide member 73. The second driving member 71 and the second guide member 73 are mounted on the fixed bracket 1. The first fixed seat 61 is slidably mounted on the second guide member 73. The second driving member 71 drives the first fixed seat 61 to move in the first direction a and the opposite direction through the second transmission assembly 72. The second driving member 71 can be a motor, and the second guide member 73 can be a guide rail. The second transmission assembly 72 includes a first pulley 721, a second pulley 722, and a first belt 723. The first pulley 721 is connected to the second driving member 71, the second pulley 722 is mounted on the fixed bracket 1, the first belt 723 is sleeved on the first pulley 721 and the second pulley 722, and the first fixed seat 61 is connected to the first belt 723.

[0042] In this embodiment, the detection device further includes a third moving mechanism 8, which is mounted on a fixed support and is used to move the microscope 3 along the third direction b and the opposite direction to adjust the gap between the microscope 3 and the detection platform 2, thereby playing a focusing role and ensuring that the microscope 3 can acquire a clear image.

[0043] The third moving mechanism 8 includes a third driving member 81, a third transmission assembly 82, and a third guide member 83. The third driving member 81 and the third guide member 83 are mounted on the fixed bracket 1. The microscope 3 is slidably connected to the third guide member 83. The third driving member 81 drives the microscope 3 to move along the third direction b and the opposite direction through the third transmission assembly 82. The third driving member 81 can be a motor, and the third guide member 83 can be a guide rod. The third transmission assembly 82 includes a second lead screw 821 and a second lead screw nut 822.

The second lead screw nut 822 is mounted on the second lead screw 821 and is slidably connected to the third guide member 83. The microscope 3 is mounted on the lead screw nut.

[0044] On the other hand, a urine analyzer is also provided, including a detection device as described above, and further including a base, a sample storage device, a reagent storage device, a counting plate 9 pushing device, and a sample transfer device. The sample storage device, reagent storage device, counting plate 9 pushing device, sample transfer device, and detection device are all mounted on the base.

[0045] The counting plate 9 pushing device is used to push the counting plate 9 onto the detection device. When pushing the counting plate 9 onto the detection device, the first guide surface 521 of the counting plate 9 abuts against the first guide surface 521 of the second fixing member 52, thereby causing the second fixing member 52 to slide along the guide post 531, thus compressing the elastic member. After the counting plate 9 is fully pushed into the counting plate limiting groove 511, the second fixing member 52, under the action of the restoring force of the elastic member, closes the opening of the counting plate limiting groove 511, thereby fixing the counting plate 9 within the counting plate limiting groove 511. The sample transfer device is used to transfer the sample stored in the sample storage device and the reagent stored in the reagent storage device to the counting plate 9, specifically to the observation area of ​​the counting plate 9, so that the detection device can perform detection. It can be understood that before pushing the counting plate 9 into the counting plate limiting groove 511, the sample transfer device has already added the sample and reagent to the observation area to avoid interference between the sample transfer device and the detection device.

[0046] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0047] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model.
