In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The present invention provides a sample detection apparatus 1.
As shown in fig. 1-3, in one embodiment, the sample testing device 1 includes a testing unit 20, a stage 30, a pushing assembly 40, a sample buffer assembly 50, and a re-pushing assembly 60.
The detecting unit 20 in this embodiment may be an image detecting module, and specifically may be an image collecting unit including a CCD (Charge-coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor, and in a using process, the image collecting module collects an image of a sample to be detected and compares the collected image with an image of a standard sample, so as to obtain a detection result, and further, the detecting unit may further analyze the collected image and compare the analysis result with the standard sample, so as to obtain a detection result for the current sample to be detected.
The type of the detecting unit 20 itself in this embodiment can be selected from various existing or improved detecting units 20 and their combinations, such as one or more of a physical detecting module, a chemical detecting module and a biological analyzing module, according to the specific situation and the detecting items.
The stage 30 in this embodiment is disposed corresponding to the detecting unit 20, and a detecting position is defined on the sample detecting device 1, and the detecting unit 20 is disposed corresponding to the detecting position and detects the inspection sample located on the detecting position during operation. In one embodiment, the stage 30 is provided with a detection track, and during use, the sample to be detected is accommodated in the carrier, the carrier moves to the detection position along the detection track, and the detection unit 20 is used to detect the sample to be detected.
The shape of the detection track in this embodiment matches with the carrier carrying the sample to be detected, and it should be understood that the sample to be detected may be carried by a corresponding carrier in the detection process, for example, in conventional blood detection, a blood sample needs to be collected by a blood sampling bottle, and further, a slide is used as a carrier to place the blood sample on a detector for detection, and then the shape and size of the corresponding guide rail need to match with the slide used, so that the slide can slide in the detection track.
The pushing assembly 40 in this embodiment is disposed at one side of the object stage 30, specifically, the pushing direction thereof is aligned with the direction of the detection track, and when in use, the carrier carrying the inspection sample is pushed to the detection position along the detection track for being detected by the detection unit 20. It should be understood that, in order to make the process of pushing the carrier more smooth, the pushing assembly 40 includes a pushing rod or a pushing plate, and is sized to match the detection track so as to push the carrier to a designated position of the detection position along the detection track.
The pushing component 40 can execute a pushing action, wherein the pushing action specifically includes a pushing action, and in the using process, the pushing component 40 pushes the inspection sample into the detection position by executing the pushing action, and further detects the inspection sample through the detection unit 20.
The sample buffer assembly 50 is further included in this embodiment, the sample buffer assembly 50 is located on a side of the stage 30 away from the pushing assembly 40, and is used for storing the sample to be tested pushed by the pushing assembly 40. In the using process, after the detection of one inspection sample is finished, a certain time is still needed to be consumed for obtaining the detailed information of the inspection sample according to the acquired information, and if the inspection sample is stored on the detection position, the time is wasted. The pushing component 40 in this embodiment can perform a pushing action to push the detected sample that has not yet obtained the sample information to the sample caching component 50 for temporary storage, and can further detect the next sample to be detected, thereby realizing continuous detection.
The push-back component 60 in this embodiment is located at a side of the sample buffer component 50 away from the detection track, and can perform a push-back action to push the retest sample out of the sample buffer component 50 and push the retest sample to the detection position, so that the detection unit 20 can perform the retest on the retest sample.
In one embodiment, the push-back assembly 60 is configured with reference to the pushing assembly 40 and is disposed on a side of the sample buffer assembly 50 away from the stage 30.
In another embodiment, the push-back assembly 60 may also be configured as the same as the push assembly 40, and the relative position between the push-back assembly and the object stage 30 is adjusted by an adjusting device so that the push-back assembly can perform the push-back action. For example, the adjusting device may be a turntable, when performing the pushing action, the pushing assembly is located on one side of the object stage 30, and when it is required to perform the pushing action, the turntable rotates to drive the pushing assembly 40 to rotate to the other side of the object stage 30 to serve as the pushing assembly 60 to perform the pushing action.
In this embodiment, the retest sample is a censorship sample satisfying a preset condition, and the preset condition should be set according to an actual situation. For example, in one embodiment, when a sample is retested, the predetermined condition may be set such that the mantissa of the sample number is an odd number, and when the sample is in use, the retested sample with the odd-numbered mantissa may be confirmed as the retested sample. In another embodiment, when a retest is performed on a test sample with a positive test result, the test sample with a positive test result is confirmed as a retest sample after the test result of the test sample is first obtained. In other embodiments, a review sample may be determined manually and further reviewed.
In this embodiment, the working state of the sample detection apparatus is defined as two states, i.e., a general detection state and a retest state, and when the sample detection apparatus is in the general detection state, the pushing component 40 executes a pushing action to push the detection sample to the detection position for detection by the detection unit 20; when the sample is in the retest state, the retest module 60 operates and performs a retest push operation to push the retest sample from the sample buffer module 50 to the detection position, so that the detection unit 20 can obtain the sample information of the retest sample, thereby implementing the retest of the retest sample.
Further, in another embodiment, the sample buffer assembly 50 includes a sample storage member and a displacement device, the sample storage member forms a plurality of sample storage positions thereon, the sample storage member cooperates with the displacement device, so that the positions of different review samples in the sample buffer assembly 50 correspond to the detection tracks, and the review samples are further pushed into the detection positions by the review module 60 for review.
It should be understood that, the displacement device in this embodiment may specifically drive the sample storage element to move so as to make different reinspection samples correspond to the detection track, or may directly drive the reinspection samples located in the sample storage element to move so as to make the positions of the different reinspection samples correspond to the detection track.
Referring to fig. 1, in one embodiment, the sample storage is stationary, and the displacement device directly drives the retest samples in the sample storage to move, so that the positions of the different retest samples correspond to the detection tracks.
In this embodiment, the sample storage component is specifically a cache track 51A, and the number of the cache tracks 51A may be one; however, in other embodiments, multiple buffer tracks 51A may be provided to accommodate more review samples. It should be understood that the relative positions of the plurality of cache tracks 51A are not fixed, and it is preferable that the plurality of cache tracks 51A are arranged parallel to each other.
The buffer track 51A forms a sample storage location, and the displacement device may be a device for moving a sample to be reinspected, such as a drag hook (not shown) or a manipulator (not shown), and the specific structure of the displacement device may refer to the existing drag hook and manipulator for driving the sample to move in the track, and the drag hook is taken as an example in this embodiment. In the using process, the reinspection samples in the buffer track 51A move back and forth along the buffer track 51A under the driving of the draw hook, so that the positions of different reinspection samples correspond to the detection tracks.
In another embodiment, the displacement device drives the sample storage member to move so that different reinspection samples correspond to the detection track.
As shown in fig. 2 and 3, in this embodiment, the sample storage member is a sample storage case 51B, the sample storage locations are sample storage compartments 53 formed in the sample storage case 51B, the sample storage case 51B includes a frame and a partition 54, the partition 54 is fixed to the frame or detachably disposed on the frame, and the sample storage compartments 53 are formed between the frame and the partition 54.
The frame in this embodiment is a cubic frame, and the front and back sides of the frame are openings, wherein the front side in this embodiment refers to the side facing the object stage 30 in the normal use state, and the back side refers to the side facing away from the object stage 30. A plurality of transverse and vertical partition plates 54 are arranged in the frame, a plurality of sample storage cells 53 are formed between the partition plates 54 and the frame, and the detected sample to be detected is pushed into different sample storage cells 53 by the pushing assembly 40 to be temporarily stored.
As shown in fig. 3, in a specific embodiment, the sample storage box 51B only includes a column of vertically distributed sample storage cells 53, and the sample storage box is driven by the displacement device to move up and down to enable different sample storage cells 53 to correspond to the position of the detection track, so that the detection sample located in the detection track is pushed to the sample storage cell 53 corresponding to the detection track by the pushing assembly.
In another embodiment, including two sample storage bits of vertical distribution in the sample storage box, and every sample storage bit of arranging all has a plurality ofly, then displacement device can drive sample storage box horizontal and vertical removal to the realization makes different sample storage bits align with the detection track.
In some embodiments, the displacement device may be implemented by a screw rod mechanism, specifically, the screw rod is driven to rotate by the driving device, and further the slide block arranged on the screw rod is driven to move by the screw rod; in other embodiments, the sample storage member may be driven to move by an air cylinder, an oil cylinder or other transmission structure.
Further, in an embodiment, the pushing component 40 is further configured to perform a pushing action of pushing the inspection sample or the review sample out of the inspection position; the push-back component 60 is also used for executing a push-back action of pushing the reinspected sample out of the detection position.

It should be understood that the process of the pushing component 40 executing the pushing action and the process of the re-pushing component 60 executing the re-pushing action are similar to the process of executing the pushing action and the re-pushing action, and the only difference is that the stroke of the pushing process is different. The specific pushing travel route should be reasonably adjusted according to the pushing end position of the to-be-detected sample and the retest sample.
In this embodiment, the submission sample is pushed to the sample buffer module 50 for storage, so that the submission sample can be stored in the sample buffer module 50 during the period from the completion of the submission sample detection to the acquisition of the detection result, and after a certain sample is confirmed to be a retest sample, the retest sample is pushed from the sample buffer module 50 to the detection position again through the retest module 60 at any time, and the submission sample is retested by using the detection unit 20, so that the submission sample needing retest can be quickly and effectively retested.
In one embodiment, considering that the pushing assembly 40 or the re-pushing assembly 60 may not be able to accurately push the sample to be tested to the testing position, a translation assembly (not shown) is further disposed between the stage 30 and the substrate on which the stage 30 is disposed to finely adjust the position of the stage 30 so that the sample to be tested located in the testing track is located at the testing position.
