[0039] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of one embodiment of the detection device of this application. Figure 2This is a schematic diagram of the structure of a detection station according to an embodiment of the present application. The detection device 1 provided in this embodiment is installed in a blood analyzer and is used to detect samples. The detection device 1 includes a detection station 11, a detection light source 12, and a collection component 13.

[0040] The detection stage 11 has a placement slot for placing the detection chip carrying the sample; the detection light source 12 is disposed on one side of the detection stage 11 for emitting a light beam to the detection chip; the acquisition component 13 is disposed on the other side of the detection stage 11, and the acquisition component 13 and the detection light source 12 are spaced apart along a first direction X, wherein the first direction X can be the height direction of the detection device 1, and the acquisition component 13 is used to receive the light beam passing through the detection chip.

[0041] Specifically, the detection light source 12 emits a light beam towards the detection chip. After passing through the sample on the detection chip, the light beam is collected by the acquisition component 13. Then, the analysis component in the detection device 1 analyzes the light beam collected by the acquisition component 13 to obtain the detection result of the sample. However, since the lens of the acquisition component 13 is set upwards, it is more prone to accumulating environmental dust, which affects the efficiency of light beam collection.

[0042] Therefore, this application embodiment further proposes that the detection platform 11 is provided with a dustproof groove 111 on the side near the acquisition component 13. Thus, when the acquisition component 13 is in a dormant state, the end of the acquisition component 13 near the detection platform 11, that is, the lens part of the acquisition component 13, can be located in the dustproof groove 111, to prevent environmental dust from accumulating on the acquisition component 13 and to maintain the cleanliness of the acquisition component 13. At the same time, since the dustproof groove 111 is provided on the detection platform 11, the detection device 1 does not need to be provided with a conventional dustproof cover. The acquisition component 13 can be protected inside the device, ensuring the automation of the operation of the detection device 1, improving the detection efficiency of the detection device 1, and enhancing the user's experience of using the detection device 1.

[0043] Optionally, the detection device 1 further includes a mounting base 14 and a guide rail assembly 15. The guide rail assembly 15 is disposed on the mounting base 14 and extends along the second direction Y, wherein the second direction Y is perpendicular to the first direction X, and the second direction Y can be the width direction of the detection device 1.

[0044] The detection platform 11 is mounted on the guide rail assembly 15. The placement slot and the dustproof slot 111 can be spaced apart on the detection platform 11 along the second direction Y. The guide rail assembly 15 drives the detection platform 11 to slide along the second direction Y, thereby enabling the dustproof slot 111 on the detection platform 11 and the acquisition component 13 to be spaced apart along the first direction X. At this time, the detection platform 11 is in the first state. Alternatively, the placement slot and the acquisition component 13 on the detection platform 11 can be spaced apart along the first direction X. At this time, the detection platform 11 is in the second state.

[0045] Specifically, the acquisition component 13 and the detection light source 12 can also be mounted on the mounting base 14, and the acquisition component 13 is mounted at one end of the guide rail assembly 15. Since the guide rail assembly 15 extends along the second direction Y, it can drive the detection stage 11 to slide along the second direction Y. During the sliding process, the dustproof groove 111 or the placement groove on the detection stage 11 will be located between the detection light source 12 and the acquisition component 13. That is, the dustproof groove 111 and the acquisition component 13 are spaced apart along the first direction X, or the placement groove and the acquisition component 13 are spaced apart along the first direction X.

[0046] Furthermore, when the acquisition component 13 is in a dormant state, that is, when the detection device 1 is in an idle state and does not detect the sample, the guide rail assembly 15 drives the detection stage 11 to slide, so that the detection stage 11 switches to the first state. The dustproof groove 111 and the acquisition component 13 are spaced apart along the first direction X, so that the acquisition component 13 can move close to the dustproof groove 111, so that one end of the acquisition component 13 is placed in the dustproof groove 111. The dustproof groove 111 isolates environmental dust from the acquisition component 13, ensuring the cleanliness of the acquisition component 13.

[0047] When the acquisition component 13 is in working state, that is, when the detection device 1 is detecting the sample, the acquisition component 13 needs to acquire the light beam. At this time, the guide rail component 15 drives the detection stage 11 to switch to the second state. The placement slot on the detection stage 11 and the acquisition component 13 are set at intervals along the first direction X. The acquisition component 13 can acquire the light beam passing through the detection chip in the placement slot, and then the detection device 1 can detect the sample carried on the detection chip and obtain the detection result.

[0048] The guide rail assembly 15 drives the movement of the detection stage 11, allowing the detection stage 11 to switch between the first and second states. This enables the detection chip to be moved to the working area of ​​the acquisition component 13, or the dustproof groove 111 to be moved to one end of the acquisition component 13, thus isolating the acquisition component 13 from environmental dust, ensuring the cleanliness of the acquisition component 13, improving the detection efficiency of the detection device 1, and enhancing the user's experience with the detection device 1.

[0049] Optionally, the detection device 1 also includes a lifting assembly (not shown).

[0050] The acquisition component 13 is mounted on the mounting base 14 via a lifting component, which in turn enables the acquisition component 13 to move in the first direction X.

[0051] Specifically, when the detection station 11 is in the first state, that is, when the acquisition component 13 and the dustproof tank 111 are spaced apart along the first direction X, the lifting component drives the acquisition component 13 to rise along the first direction X, so that one end of the acquisition component 13 is placed in the dustproof tank 111. The dustproof tank 111 isolates the acquisition component 13 from environmental dust, ensuring the cleanliness of the acquisition component 13.

[0052] When the testing device 1 needs to test a sample, the lifting assembly can drive the acquisition assembly 13 to descend along the first direction X, causing the acquisition assembly 13 to detach from the dustproof groove 111. The rear guide rail assembly 15 can then move the testing table 11, switching it to the second state. By first removing the acquisition assembly 13 from the rear guide rail assembly 15 and then moving the testing table 11, damage to the acquisition assembly 13 located in the dustproof groove 111 is avoided during the movement of the testing table 11. This improves the safety of the internal components of the testing device 1 and enhances its practicality.

[0053] Optionally, the detection stage 11 is also provided with a light transmission hole 112, which is located at the bottom of the placement slot to allow the light beam illuminating the detection chip to enter the acquisition component 13 through the light transmission hole 112.

[0054] Specifically, the detection chip carrying the sample is placed in the placement slot, and the detection light source 12 emits a light beam to illuminate the detection chip. Due to the presence of the light transmission hole 112, the light beam passes through the detection chip and enters the acquisition component 13 through the light transmission hole 112. The acquisition component 13 collects the light beam carrying the information of the sample on the detection chip, and thus the detection device 1 can obtain the detection result of the sample.

[0055] Optionally, the detection device 1 may further include a detection sensor 16, which is connected to the acquisition component 13 and is used to receive the light beam acquired by the acquisition component 13 and obtain the detection result of the sample on the detection chip based on the light beam.

[0056] Optionally, the guide rail assembly 15 includes a sliding guide rail 151, a slider 152, at least two synchronous pulleys 153, a conveyor belt 154, and a drive motor 155.

[0057] The sliding guide rail 151 is mounted on the mounting base 14 and extends along the second direction Y. The slider 152 is mounted on the sliding guide rail 151 and slides relative to it. At least two synchronous pulleys 153 are spaced apart along the second direction Y. A conveyor belt 154 surrounds the synchronous pulleys 153, and the extension direction of the conveyor belt 154 is parallel to the extension direction of the sliding guide rail 151. One end of the slider 152 is mounted on the conveyor belt 154, allowing the conveyor belt 154 to drive the slider 152. A drive motor 155 is connected to any one of the synchronous pulleys 153 to drive the synchronous pulley 153 to rotate, thereby driving the conveyor belt 154 to move the slider 152 along the second direction Y on the sliding guide rail 151. A detection table 11 is mounted on the slider 152.

[0058] Specifically, when the testing station 11 needs to switch states, such as from the second state to the first state, or from the first state to the second state, the drive motor 155 first drives the synchronous pulley 153 connected to it to rotate, which in turn drives the conveyor belt 154 surrounding the synchronous pulley 153. The transmission of the conveyor belt 154 will drive other synchronous pulleys 153 not connected to the drive motor 155 to rotate, thereby achieving the stability of the transmission of the conveyor belt 154. Furthermore, since one end of the slider 152 is set on the conveyor belt 154, the transmission of the conveyor belt 154 will drive the slider 152 to move; and since the extension direction of the conveyor belt 154 is parallel to the extension direction of the sliding guide rail 151, the conveyor belt 154 can drive the slider 152 to move along the second direction Y on the sliding guide rail 151. The testing station 11 is set on the slider 152, and the movement of the slider 152 on the sliding guide rail 151 will drive the testing station 11 to move along the second direction Y, so that the testing station 11 switches to the first state or the second state to meet the needs of the testing device 1.

[0059] Optionally, the acquisition component 13 and the detection stage 11 are jointly mounted on a motion mechanism (not shown). By integrating the acquisition component 13 and the detection stage 11 into the same motion mechanism, when the detection device 1 is performing detection, the acquisition component 13 and the detection stage 11 are moved as a whole by synchronously driving them, thereby reducing the difference in vibration frequency between the acquisition component 13 and the detection stage 11, avoiding lens defocusing caused by excessive vibration frequency difference between the acquisition component 13 and the detection stage 11, and improving the stability of the detection device 1.

[0060] Optionally, the testing device 1 further includes an insertion component (not shown), which is spaced apart from the testing stage 11 and is used to receive the testing chip and transfer the testing chip to the placement slot of the testing stage 11.

[0061] Specifically, the insertion component can be moved relative to the blood analyzer to be located outside or inside the blood analyzer. When the insertion component is located outside the blood analyzer, the user can place the test chip carrying the sample into the insertion component. Then, the insertion component moves the test chip into the blood analyzer, spaced apart from the test station 11. The insertion component then moves the test chip it carries into the placement slot of the test station 11 so that the sample on the test chip can be tested.

[0062] The following is a brief description of the operation process of detection device 1:

[0063] Starting from the dormant state of the acquisition component 13, the lifting component first lowers the acquisition component 13 along the first direction X to disengage from the dustproof groove 111. At the same time, the insertion component places the detection chip carrying the sample onto the detection stage 11. Then, the drive motor 155 starts, the synchronous wheel 153 rotates clockwise to drive the conveyor belt 154, and the slider 152 slides on the sliding guide rail 151 to move the detection stage 11 along the second direction Y. The detection stage 11 then switches to the second state, and the light beam emitted by the detection light source 12 shines on the detection chip and is received by the acquisition component 13 through the light hole 112. Then, the detection sensor 16 receives the light beam collected by the acquisition component 13 and obtains the detection result of the sample on the detection chip based on the light beam.

[0064] After the sample on the detection chip is tested, the acquisition component 13 is in a dormant state. The moving component in the blood analyzer can remove the completed detection chip from the detection platform 11, and the drive motor 155 restarts. The synchronous wheel 153 rotates counterclockwise, driving the conveyor belt 154 to move, and the slider 152 moves the detection platform 11 along the second direction Y, switching the detection platform 11 to the first state. The lifting component drives the acquisition component 13 to rise along the first direction X, so that one end of the acquisition component 13 is located in the dustproof groove 111. The dustproof groove 111 isolates the acquisition component 13 from environmental dust, ensuring the cleanliness of the acquisition component 13 and improving the detection efficiency of the detection device 1.

[0065] In summary, in the detection device 1 of this application, the dustproof groove 111 on the detection table 11 shields the acquisition component 13, preventing environmental dust from falling on the acquisition component 13 and affecting the acquisition efficiency of the acquisition component 13 for collecting the light beam. There is no need to set up a conventional dustproof cover. The acquisition component 13 can be protected inside the device, ensuring the automation of the operation of the detection device 1, improving the detection efficiency of the detection device 1, and enhancing the user's experience of the detection device 1.

[0066] This application also provides a blood analyzer, such as Figure 3 As shown, Figure 3This is a schematic diagram of the structure of a blood analyzer according to an embodiment of this application. The blood analyzer A provided in this embodiment includes a detection device 1 as described above. The detection device 1 is used to receive a detection chip carrying a sample and to detect the sample on the detection chip to obtain the detection result of the sample.

[0067] Optionally, the blood analyzer A includes a housing 2 with a receiving space, a detection device 1 located within the receiving space, and the detection device 1 is disposed near the first side wall of the housing 2.

[0068] The first side wall is provided with a maintenance port 21 and a door (not shown in the figure). The door is rotatably positioned at the maintenance port 21 to open or close the maintenance port 21. When the door rotates relative to the maintenance port 21 to open the maintenance port 21, the acquisition component 13 of the detection device 1 is exposed through the maintenance port 21. This allows the user to clean the acquisition component 13 through the maintenance port 21 without disassembling the entire device, reducing the difficulty of cleaning the acquisition component 13 and improving cleaning efficiency.

[0069] When the maintenance port 21 is closed, the storage space is sealed to prevent environmental dust from entering the storage space through the maintenance port 21 and affecting the detection device 1 or other operating components in the storage space, thereby improving the stability of the blood analyzer A's operation.

[0070] In one embodiment, the door can be magnetically connected to the maintenance port 21 to close the maintenance port 21. In other embodiments, other connection structures may be used, and this application does not limit them.

[0071] In summary, in the blood analyzer A provided by this application, the user can clean the acquisition component 13 through the maintenance port 21, and the detection device 1 is provided with a dustproof groove 111 that isolates the acquisition component 13 from environmental dust, which further ensures the cleanliness of the acquisition component 13, ensures the acquisition efficiency of the acquisition component 13 for the light beam, improves the detection efficiency of the detection device 1, and improves the operating efficiency of the blood analyzer A.

[0072] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
