Technical Field

[0001] This utility model relates to the technical field of visual detection light sources for blood stratification, and in particular to a visual detection light source device for blood stratification. Background Technology

[0002] A visual detection light source device for blood stratification, as the name suggests, involves placing a container filled with blood (usually a test tube) for a period of time, illuminating the blood container at a specific angle using a light source, and then using an observation device (usually a camera) to observe and photograph the side wall of the blood container. The photographs are then uploaded to a host computer for automated detection, thus achieving automated visual detection of blood stratification. (Visual detection of blood stratification is generally used to observe the stratification of serum / white blood cells / red blood cells in blood.)

[0003] However, existing visual inspection light source devices for blood stratification are not standardized; they are typically temporary installations built according to site requirements and lighting conditions. Generally, these devices include a robotic arm holding the blood container, a surface light source below the container for illumination, a reflector on one side of the container for reflection, and a photographic device on the other side for taking pictures. (Alternatively, a ring light source or dome light source can be installed on one side of the blood container, with the photographic device positioned next to it for taking pictures; or the setup can be customized based on site requirements, lighting conditions, and the characteristics of the light source structure.)

[0004] However, the visual detection light source device for blood stratification in the prior art has the following drawbacks:

[0005] 1. Disassembly, assembly, repair, debugging, and use are cumbersome;

[0006] 2. The structural layout has a large space, but the applicable scenarios are relatively narrow;

[0007] 3. Poor detection results. (The light source, blood container, photographic equipment, and reflector require adjustments based on the on-site lighting conditions and human experience, which often results in suboptimal detection results.) Utility Model Content

[0008] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a blood layer visual detection light source device that is simple to disassemble, repair, debug and use; has a small structural layout space, making it more convenient for users to arrange; and is applicable to a wide range of scenarios; and has stable and better detection results.

[0009] To achieve the above objectives, this utility model provides a blood stratification visual detection light source device, including a peripheral structure, an annular cavity inside the peripheral structure, a first light source component at one end of the annular cavity and a second light source component at the other end, an observation window on one side of the annular cavity, and a detection inlet for inserting a blood container into the annular cavity in the middle of the first light source component.

[0010] Preferably, the inner sidewalls of the annular cavity are coated with a diffuse reflection coating.

[0011] Preferably, the annular cavity has a first mounting hole at one end, and the first light source assembly includes a first base sleeved on the first mounting hole, a first annular PCB board mounted on one end of the first base, and a plurality of first LED beads evenly arranged on the first annular PCB board. The detection inlet is located on the first base.

[0012] Preferably, the sidewall of the first base and one end of the sidewall of the peripheral structure are fixed together by bolts.

[0013] Preferably, one end of the first base and the first annular PCB board are fixed together by screwing in bolts.

[0014] Preferably, a first through hole is formed between one side of the first base and one side of the peripheral structure, and a first power line electrically connected to the first annular PCB board is connected to one side of the peripheral structure, the first power line passing through the through hole.

[0015] Preferably, the other end of the annular cavity is provided with a second mounting hole, and the second light source assembly includes a second base sleeved on the second mounting hole, a second annular PCB board mounted on one end of the second base, and a number of second LED beads evenly arranged on the second annular PCB board.

[0016] Preferably, the second base sidewall and the other end sidewall of the peripheral structure are fixed together by bolts.

[0017] Preferably, one end of the second base and the second annular PCB board are screwed together and fixed together.

[0018] Preferably, a second through hole is provided between one side of the second base and one side of the other end of the peripheral structure, and a second power line electrically connected to the second annular PCB board is connected to one side of the other end of the peripheral structure, and the second power line passes through the second through hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This invention inserts a blood container into an annular cavity through a detection inlet. Then, the first and second light source components are activated, emitting light into the annular cavity. The light diffuses within the annular cavity, ensuring that the light is evenly distributed onto the sidewalls of the blood container. This allows the observation device positioned above the observation window to perform observations. Therefore, this invention has the following advantages:

[0021] A. Simple structure, easy to disassemble, repair, debug and use.

[0022] In addition, the modular design with independent power supply to both the first and second light source components allows for quick replacement of one of the light source components if it fails.

[0023] B. The structure has a small layout space, good versatility and adaptability, making it easy for users to deploy in smaller usage scenarios, and it can also be quickly adapted to blood containers of various sizes;

[0024] C. Better detection effect: The dual-end independent power supply of the first and second light source components allows for easy adjustment of the brightness distribution at the top and bottom of the blood container, thus facilitating the adjustment to achieve the best supplementary lighting effect. Furthermore, the use of annular wall diffuse reflection settings enables highly uniform supplementary lighting at the top and bottom of the blood container, allowing the observation equipment to clearly observe the side wall imaging of the blood container.

[0025] 2. In summary, the blood stratification visual inspection light source device of this utility model is simple to disassemble, repair, debug and use; its structural layout requires less space and is applicable to a wide range of scenarios; and its detection effect is stable and better.

Based on this embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1 to 5 The present invention provides a blood stratification visual detection light source device, including a peripheral structure 1, an annular cavity 2 inside the peripheral structure 1, a first light source component 3 at one end of the annular cavity 2 and a second light source component 4 at the other end, an observation window 5 on one side of the annular cavity 2, and a detection inlet 6 in the middle of the first light source component 3 for inserting a blood container into the annular cavity 2.

[0036] The inner sidewall of the annular cavity 2 is coated with a diffuse reflection coating. The diffuse reflection coating is a PTFE-based material with a reflectivity >95%. Through the diffuse reflection coating of the annular cavity 2, the light emitted by the first light source assembly 3 and the second light source assembly 4 can be scattered in multiple stages, eliminating the direct light path and forming highly uniform diffuse reflection, thereby preventing the observation equipment from observing the sidewall of the blood container from the observation window 5;

[0037] The annular cavity 2 has a first mounting hole 11 at one end. The first light source assembly 3 includes a first base 31 sleeved on the first mounting hole 11, a first annular PCB board 32 mounted on one end of the first base 31, and a number of first LED beads 33 evenly arranged on the first annular PCB board 32. The detection entrance 6 is opened on the first base 31.

[0038] The sidewall of the first base 31 and one end of the sidewall of the peripheral structure 1 are fixed together by bolts, and one end of the first base 31 and the first annular PCB board 32 are fixed together by bolts. This structural design ensures that one end of the peripheral structure 1, the first base 31, and the first annular PCB board 32 are securely installed.

[0039] A first through hole 34 is provided between one side of the first base 31 and one side of the peripheral structure 1. A first power line 35, which is electrically connected to the first annular PCB board 32, is connected to one side of the peripheral structure 1 and passes through the through hole. The first power line 35 is used to individually control the first LED bead 33 on the first annular PCB board 32 to emit light.

[0040] The other end of the annular cavity 2 is provided with a second mounting hole 12. The second light source assembly 4 includes a second base 41 sleeved on the second mounting hole 12, a second annular PCB board 42 mounted on one end of the second base 41, and a number of second LED beads 43 evenly arranged on the second annular PCB board 42.

[0041] The side wall of the second base 41 and the other side wall of the peripheral structure 1 are fixed together by bolts. One end of the second base 41 and the second annular PCB board 42 are fixed together by bolts. This structure ensures that one end of the peripheral structure 1, the first base 31 and the first annular PCB board 32 are securely installed.

[0042] A second through hole 44 is provided between one side of the second base 41 and one side of the other end of the peripheral structure 1. A second power line 45, which is electrically connected to the second annular PCB board 42, is connected to one side of the other end of the peripheral structure 1. The second power line 45 passes through the second through hole 44. The second power line 45 is used to individually control the second LED bead 43 on the second annular PCB board 42 to emit light.

[0043] The perimeter structure 1 is cylindrical or rectangular, and the observation window 5 and the detection entrance 6 are both circular or rectangular.

[0044] An embodiment of the present invention provides a blood stratification visual detection light source device, which is used as follows:

[0045] S1: Installation and fixing (e.g.) Figure 5(As shown): The blood layer visual detection light source device is erected and fixed, that is, the first light source component 3, the annular cavity 2 and the second light source component 4 are arranged vertically from top to bottom. Then, the first bracket or the first robotic arm of the prior art is used to grab the observation device, the lens of the observation device is aligned with the observation window 5, and then the lifting device + the second bracket combination or the second robotic arm of the prior art is used to grab the blood container, the blood container is located directly above the detection inlet 6.

[0046] S2: Usage: The first light source component 3 is controlled to emit light through the first power line 35, and the second light source component 4 is controlled to emit light through the second power line 45. By controlling the lifting device or the second robotic arm to lift and lower, the blood container enters the annular cavity 2 through the detection inlet 6, so that the lens of the observation device is aimed at the side wall of the blood container to take pictures, thereby enabling the observation device to observe the blood stratification on the side wall of the blood container.

[0047] The technical advantages of the blood stratification visual detection light source device according to an embodiment of this utility model are as follows:

[0048] 1. Simple structure, easy to disassemble, repair, debug and use.

[0049] In addition, the modular design with independent power supply at both ends for the first light source component 3 and the second light source component 4 allows for quick replacement of one of the light source components when it is damaged, greatly reducing the time required for troubleshooting.

[0050] 2. The structure has a small layout space, good versatility and adaptability, avoids the use of additional existing technology brackets to fix the light source, avoids waste of layout space, makes it easy for users to set up in smaller usage scenarios, and can also be quickly applied to blood containers of various sizes.

[0051] 3. Improved detection performance: The dual-end independent power supply of the first light source component 3 and the second light source component 4 allows for easy adjustment of the brightness distribution at both ends of the blood container, facilitating optimal supplementary lighting. Furthermore, the annular wall diffuse reflection design significantly reduces glare from the blood container, enabling highly uniform supplementary lighting at both ends and minimizing brightness differences. This effectively eliminates blind spots in the vertical direction of the blood container's sidewall, allowing the observation equipment to clearly observe the sidewall image. Additionally, the observation equipment is not aligned with the first light source component 3 and the second light source component 4, effectively preventing the observation equipment's lens from capturing shadows on the first LED bead 33 and the second LED bead 43.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
