Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

The embodiment of the utility model provides sample image scanning equipment which is used for scanning and analyzing samples on a glass slide, wherein the samples comprise at least one of blood samples, urine samples, sputum samples, gynecological samples, liquid-based samples and other biological samples. The sample image scanning apparatus photographs an image of a sample on a slide by a microscope, and obtains a detection result through observation, analysis and judgment, and the detection result can assist in diagnosing a disease.

Referring to fig. 1 and 2, a sample image scanning apparatus 100 according to an embodiment of the present utility model includes a transfer device 10, a slide scheduling device 20, and a scanning device 30. The transfer device 10 includes an advancing mechanism 11 and a slide transfer mechanism 12 for holding the slide 200, the slide transfer mechanism 12 being provided on the advancing mechanism 11. The advancement mechanism 11 is used to drive the slide relay mechanism 12 to reciprocate between the first position and the second position so that the slide relay mechanism 12 can reciprocate the slide 200 between the third position and the scanning position 31. The first position corresponds to the third position and the second position corresponds to the scan bit 31. The slide scheduler 20 is used to transport slides 200 to the slide relay mechanism 12 at the first location, and the scanner 30 is used to scan the slides 200 at the scan location 31.

The sample image scanning apparatus 100 of the above embodiment has a reasonable structural design, the slide transfer mechanism 12 is used for clamping the slide 200, and the advancing mechanism 11 is used for driving the slide transfer mechanism 12 to reciprocate between the first position and the second position so that the slide transfer mechanism 12 can reciprocate the slide 200 between the third position and the scanning position 31; the slide transfer mechanism 12 is arranged on the advancing mechanism 11, so that the structure is compact, the integration level of the sample image scanning device 100 is improved, and the volume and the occupied area of the sample image scanning device 100 are reduced. In addition, the slide transfer mechanism 12 can buffer the slide 200, and has functions of conveying and temporary transfer storage, so that actions of different devices of the sample image scanning device 100 can be performed in parallel, the scanning flow time is saved, and the scanning detection efficiency and the device operation efficiency are improved. In addition, the second position of the slide transfer mechanism 12 corresponds to the scanning position 31, and the slide transfer mechanism 12 can directly convey the slide 200 on the slide transfer mechanism 12 to the scanning position 31 under the driving of the advancing mechanism 11, so that an additional slide moving mechanism is not required to push or grab the slide 200 on the slide transfer mechanism 12 to the scanning position 31, and the number of components and the time of the scanning process are reduced.

Referring to fig. 2 and 3, in some embodiments, the transfer device 10 further includes a slide state switching mechanism 13, and the slide state switching mechanism 13 is connected to the advancing mechanism 11 and the slide transfer mechanism 12. The slide state switching mechanism 13 is for driving the slide relay mechanism 12 to rotate to switch the slide 200 on the slide relay mechanism 12 between the vertical state and the horizontal state. Thus, on the one hand, the advancing mechanism 11 of the relay device 10 is capable of driving the slide relay mechanism 12 and the slide 200 held on the slide relay mechanism 12 to move to reciprocate the slide 200 between the third position and the scanning position 31; on the other hand, the slide state switching mechanism 13 of the transfer device 10 can drive the slide transfer mechanism 12 to rotate so as to switch the slide 200 clamped by the slide transfer mechanism 12 between a vertical state and a horizontal state, thereby further improving the integration level and the structural compactness of the equipment and further reducing the volume and the occupied area of the whole machine.

Illustratively, when the slide 200 on the slide relay mechanism 12 needs to be switched between the vertical state and the horizontal state, the slide state switching mechanism 13 is configured to drive the slide relay mechanism 12 to rotate by at least 90 °, such as by an odd multiple of 90 °, for example, 90 °, 270 °, 450 °.

Illustratively, the slide 200 on the slide relay mechanism 12 is in a horizontal state in fig. 2, and the slide 200 on the slide relay mechanism 12 is in a vertical state in fig. 4. Illustratively, the slide relay mechanism 12 in fig. 4 is in the first position.

In some embodiments, after the slide scheduling device 20 conveys the slide 200 in the vertical state onto the slide relay mechanism 12, the slide state switching mechanism 13 is used to drive the slide relay mechanism 12 to rotate so that the slide 200 on the slide relay mechanism 12 is switched from the vertical state to the horizontal state.

In some embodiments, after the slide 200 is transferred from the scanning position 31 to the third position, the slide state switching mechanism 13 is configured to drive the slide relay mechanism 12 to rotate so that the slide 200 on the slide relay mechanism 12 is switched from the horizontal state to the vertical state.

Illustratively, when a scan analysis is required for a sample on a slide 200, the slide scheduler 20 conveys the slide 200 in a vertical state to the slide relay mechanism 12 located at the first position, and the slide state switching mechanism 13 drives the slide relay mechanism 12 located at the first position to rotate to switch the slide 200 on the slide relay mechanism 12 from the vertical state to the horizontal state, and at this time, the slide 200 on the slide relay mechanism 12 is located at the third position; the advancement mechanism 11 then drives the slide relay mechanism 12 from the first position to the second position to move the slide 200 on the slide relay mechanism 12 from the third position to the scanning position 31. After the scanning analysis is completed on the sample on the slide 200, the slide relay mechanism 12 holds the slide 200 located at the scanning position 31 (the slide on the scanning position 31 is in a horizontal state), and the advancing mechanism 11 drives the slide relay mechanism 12 to be transported from the second position to the first position so that the slide 200 on the slide relay mechanism 12 is moved from the scanning position 31 to the third position; then, the slide state switching mechanism 13 drives the slide relay mechanism 12 located at the first position to rotate to switch the slide 200 on the slide relay mechanism 12 from the horizontal state to the vertical state, and then the slide scheduling device 20 takes out the slide 200 in the vertical state from the slide relay mechanism 12 located at the first position to other positions (such as a slide recovery bin or a recovery slide basket). It will be appreciated that the slide state switching mechanism 13 illustratively includes a state switching motor for driving the slide relay mechanism 12 to rotate, thereby switching the slide 200 on the slide relay mechanism 12 between the horizontal state and the vertical state.

Illustratively, when the slide relay mechanism 12 is in the first position and the slide 200 on the slide relay mechanism 12 is in a horizontal state, the slide 200 on the slide relay mechanism 12 is in the third position. When the slide relay mechanism 12 is located at the second position, the slide 200 held by the slide relay mechanism 12 is located at the scanning position 31.

The first position and the third position may be the same position or different positions, and the second position and the scanning position 31 may be the same position or different positions. For example, the first position and the third position are different, and the second position and the scanning position 31 are different, so that the transfer device 10 can perform the functions of transporting and transferring the buffer slide 200, and the action interference between the components can be reduced. For example, the second position is different from the scanning position 31, so that the transfer device 10 can be guaranteed to convey the slide 200 to the scanning position 31 or move out of the scanning position 31, the probability that the slide transfer mechanism 12 and the scanning device 30 are easy to interfere in the process of conveying the slide 200 by the transfer device 10 or in the process of scanning the slide 200 of the scanning position 31 by the scanning device 30 can be reduced, and the guarantee is provided for the normal operation of the transfer device 10 and the scanning device 30.

In some embodiments, after the slide 200 on the slide relay mechanism 12 is switched from the vertical state to the horizontal state, the advancing mechanism 11 is configured to drive the slide state switching mechanism 13 to advance to drive the slide relay mechanism 12 to transport the slide 200 from the third position to the scanning position 31 so that the scanning device 30 can perform scanning analysis on the slide 200.

In some embodiments, after the scanning device 30 completes the scanning analysis of the slide 200, the advancing mechanism 11 is configured to drive the slide state switching mechanism 13 to retract to drive the slide transfer mechanism 12 carrying the tested slide 200 to transfer the slide 200 from the scanning position 31 to the third position to move the slide 200 having completed the scanning detection out of the scanning position 31, so that the scanning device 30 can perform the scanning analysis on the next slide 200.

Illustratively, the movement locus of the slide state switching mechanism 13 may be a straight line or a curved line under the drive of the advancing mechanism 11.

It will be appreciated that the slide state switching mechanism 13 may be moved to any suitable position on the movement track of the slide state switching mechanism 13 according to actual requirements, for example, any position between the first position and the second position, and is not limited to the first position and the second position.

In some embodiments, after the advancing mechanism 11 drives the slide state switching mechanism 13 to move to transport the slide 200 to the scanning position 31 and before transporting the slide 200 from the scanning position 31 to the third position, the driving mechanism is further configured to drive the slide state switching mechanism 13 back to drive the slide relay mechanism 12 to idle and exit the scanning position 31. In this way, the scanner 30 can be prevented from interfering with or colliding with the slide relay mechanism 12 when the scanner 30 scans and detects the slide 200 at the scanning position 31.

Referring to fig. 3 and 5, in some embodiments, the advancement mechanism 11 comprises a first mount 111, a first drive 112, and a first transfer assembly 113. The first driving member 112 is disposed on the first mounting base 111. The first conveying component 113 is in transmission connection with the first driving piece 112, and the first conveying component 113 is in transmission connection with the slide state switching mechanism 13 to drive the slide state switching mechanism 13 to slide relative to the first mounting seat 111. In this way, the slide state switching mechanism 13 and the slide transfer mechanism 12 have simple movement strokes, and the advancing mechanism 11 has a simple and compact structure. Illustratively, the first driver 112 includes a forward motor. The first transfer assembly 113 includes at least one of a timing belt transfer assembly, a gear transfer assembly, and the like.

Illustratively, the slide state switching mechanism 13 is capable of moving horizontally under the drive of the first drive member 112 and the first transfer assembly 113 to reciprocate the slide relay mechanism 12 horizontally between the first position and the second position, thereby causing the slide relay mechanism 12 to reciprocate the slide 200 between the third position and the scanning position 31.

It will be appreciated that the scanning device 30 will normally perform analytical testing of the sample on the slide 200 when the side of the slide 200 at the scanning location 31 coated with the sample is facing upward (i.e., the front side of the slide 200).

Referring to fig. 3 and 5, in some embodiments, the transfer device 10 further includes a slide correction mechanism 14. The slide correcting mechanism 14 is connected to the advancing mechanism 11 and the slide transferring mechanism 12, and the slide correcting mechanism 14 is configured to drive the slide transferring mechanism 12 to rotate to set the slide 200 right after the sample image scanning apparatus 100 recognizes that the slide 200 is set upside down. In this way, the transfer device 10 not only can reciprocate the slide 200 between the third position and the scanning position 31, but also can reciprocate the slide 200 between the vertical state and the horizontal state, and also can rotate and place the slide 200 right after the slide 200 is placed reversely, so that the integration level and the structural compactness of the equipment are further improved, and the volume and the occupied area of the whole machine are effectively reduced.

As can be appreciated, the sample image scanning device 100 can perform front-back identification on the slide 200, and if it is identified that the slide 200 is placed (i.e., the front surface of the slide 200 is oriented in a desired direction), then follow-up actions are normally performed; if the slide 200 is identified as being inverted, the inverted slide 200 is placed by the slide correction mechanism 14 such that the front of the slide 200 is oriented in the desired direction.

In some embodiments, after the scanning device 30 recognizes that the slide 200 is reversely placed, the advancing mechanism 11 is configured to drive the slide state switching mechanism 13 to retreat to drive the slide correcting mechanism 14 and the slide transferring mechanism 12 to retreat so that the slide transferring mechanism 12 transfers the slide 200 from the scanning position 31 to the third position; after the slide 200 on the slide relay mechanism 12 is retracted to the third position, the slide correction mechanism 14 is used to drive the slide relay mechanism 12 to rotate to place the slide 200 on the slide relay mechanism 12. The front and back sides of the slide 200 are identified at the scanning device 30, and the front and back sides of the slide 200 are identified without arranging a slide identification mechanism 41 (such as a camera and the like), so that the number of components is reduced, the cost is reduced, and the volume and the occupied area of the whole machine are reduced.

Referring to fig. 3 and 5, in some embodiments, the slide state switching mechanism 13 includes a second mount 131, a second driving member 132, and a second conveying assembly 133, where the second mount 131 is slidably connected to the first mount 111 of the advancing mechanism 11, the second driving member 132 is disposed on the second mount 131, and the second conveying assembly 133 is in driving connection with the second driving member 132. The slide correcting mechanism 14 comprises a third mounting seat 141 and a third driving piece 142 arranged on the third mounting seat 141, the third driving piece 142 is in transmission connection with the slide transferring mechanism 12, and the third mounting seat 141 is in transmission connection with the second conveying assembly 133. In this way, the slide state switching mechanism 13 and the slide correcting mechanism 14 are simple and compact in structure, and the movement strokes of the slide transferring mechanism 12 and the slide correcting mechanism 14 are simple. Illustratively, the second driver 132 includes a state switching motor. The second conveying assembly 133 includes at least one of a timing belt conveying assembly, a gear conveying assembly, and the like. Illustratively, the third drive 142 includes a slide correction motor.

The second mounting base 131 and the first mounting base 111 are slidably connected by a sliding groove and a sliding rail, for example.

In other embodiments, the slide correcting mechanism 14 may be slidably connected to the advancing mechanism 11, the slide correcting mechanism 14 being connected to the slide state switching mechanism 13, and the slide state switching mechanism 13 being connected to the slide transferring mechanism 12.

Referring to fig. 4, in some embodiments, the specimen image scanning apparatus 100 further includes a slide front and back recognition device 40. After the slide scheduling device 20 conveys the slide 200 in the vertical state to the slide transferring mechanism 12, the slide front and back identifying device 40 is used for identifying the front and back of the slide 200 in the vertical state on the slide transferring mechanism 12; after the slide front and back recognition device 40 recognizes that the slide 200 is reversed, the slide correction mechanism 14 is used to drive the slide transfer mechanism 12 to rotate to place the slide 200 on the slide transfer mechanism 12. In this way, a guarantee is provided that the scanning device 30 can perform normal scanning analysis on the slide 200 of the scanning position 31. The slide front and back recognition device 40 can perform front and back recognition on the slide 200 positioned at the front and back recognition position, and when the slide 200 is positioned at the front and back recognition position, the slide transfer mechanism 12 can be positioned at the first position or at other positions, which is not limited herein. Illustratively, when the slide relay mechanism 12 is in the first position, the slide 200 in the vertical state on the slide relay mechanism 12 is in the obverse and reverse recognition position, so that when the slide relay mechanism 12 is in the first position, the slide relay mechanism 12 can receive the slide 200 carried from the slide scheduler 20; the slide front and back recognition device 40 can recognize the front and back of the slide 200 on the slide transfer mechanism 12 at the first position, after recognizing that the slide 200 is reversely placed, the slide correction mechanism 14 can drive the slide transfer mechanism 12 to rotate so as to place the slide 200 on the slide transfer mechanism 12, and when recognizing the front and back of the slide 200 and placing the slide 200, the slide transfer mechanism 12 is not required to be driven to move to other positions except the first position by the advancing mechanism 11, so that the scanning flow of the slide 200 is saved, and the scanning detection efficiency of the slide 200 is improved.

Illustratively, the front and back identification may be determined by identifying information codes attached to the slide 200, or by identifying differences in the coating on the slide 200 when the slide 200 is placed in front of and in back of. In other embodiments, the slide front and back identification device 40 may also be used to identify the identity information of the slide 200. Identification information can be determined by identifying the information code affixed to the slide 200.

Referring to fig. 4, in some embodiments, the slide front and back recognition device 40 includes a recognition mechanism 41 and a background plate 42, where the recognition mechanism 41 is opposite to and spaced apart from the background plate 42. In the case of performing the front-back recognition of the slide 200, the slide 200 is positioned between the recognition mechanism 41 and the background plate 42. Illustratively, the recognition mechanism 41 includes an information code scanner or camera, or the like.

In some embodiments, at least one of the slide correction mechanism 14 and the slide state switching mechanism 13 may be omitted.

Referring to fig. 3 and 5, in some embodiments, the slide relay mechanism 12 includes a slide clamping mechanism 121 and an opening and closing drive mechanism 122, the opening and closing drive mechanism 122 being configured to drive the slide clamping mechanism 121 to open and close to clamp or unclamp the slide 200. The open-close driving mechanism 122 drives the slide holding mechanism 121 located at the first position to close to hold the slide 200 in the vertical state carried by the slide scheduling device 20, the slide 200 on the slide holding mechanism 121 is switched from the vertical state to the horizontal state by the slide state switching mechanism 13, the slide holding mechanism 121 is directly or indirectly driven to advance by the advancing mechanism 11 so that the slide holding mechanism 121 carries the slide 200 on the slide holding mechanism 121 to the scanning position 31, and when the slide 200 is carried to the scanning position 31, the open-close driving mechanism 122 drives the slide holding mechanism 121 to open to release the slide 200. When the slide 200 needs to be removed from the scanning position 31, the slide clamping mechanism 121 located at the second position can be driven by the open-close driving mechanism 122 to close so as to clamp the slide 200 of the scanning position 31, and the slide clamping mechanism 121 is directly or indirectly driven by the advancing mechanism 11 to retreat so that the slide clamping mechanism 121 moves the slide 200 on the slide clamping mechanism 121 out of the scanning position 31. When the slide 200 on the transfer device 10 needs to be transported to the slide dispatcher device 20, the slide clamping mechanism 121 located at the first position can be opened under the drive of the opening and closing driving mechanism 122 to release the slide 200, so that the slide dispatcher device 20 can normally receive the slide 200 on the slide clamping mechanism 121 and transport the slide 200 to other positions.

Illustratively, the slide clamping mechanism 121 may clamp one end of the slide 200 during the shuttle of the slide relay mechanism 12 between the third position and the scan position 31 to reduce the probability of interference or collision between the slide relay mechanism 12 and the scan position 31.
