The current slide reading device automatically shoots characteristic cells in a blood slide through a microscopic imaging system.

At present, a film reading device is designed with a group of optical amplification light paths, an imaging camera, a set of sample movement control device and a processor.

As shown in fig. 1 and fig. 2, an embodiment of the present invention provides a specimen interpreting device, which includes a multiple imaging device, a specimen movement control device, and a processing device. The multiple imaging device at least comprises a low-power light path and a high-power light path, and comprises an objective lens 1, a light splitting device 2, a first ocular 3, a second ocular 6, a first imaging acquisition device 4 and a second imaging acquisition device 7; after the imaging information of the sample passes through the objective lens 1, the same initial imaging information is generated in the first direction and the second direction respectively under the action of the light splitting device 2; the objective lens 1 and the light splitting device 2 form an objective lens group; the low power optical path is composed of an objective lens group, a first ocular lens 3 and a first imaging acquisition device 4, wherein the first imaging acquisition device 4 acquires first imaging information of initial imaging information in a first direction after the initial imaging information passes through the first ocular lens 3; the high-power optical path consists of an objective lens group, a second ocular 6 and a second imaging acquisition device 7, and the second imaging acquisition device 7 acquires second imaging information of initial imaging information in a second direction after the initial imaging information passes through the second ocular 6; the multiple of the second imaging information is higher than the multiple of the first imaging information; the sample movement control device is used for adjusting the movement of the sample relative to the objective lens 1; the processing device is used for processing first image information formed after the first imaging acquisition equipment 4 acquires the first imaging information and second image information formed after the second imaging acquisition equipment 7 acquires the second imaging information.

According to the sample reading device provided by the embodiment of the invention, a low-power optical path is formed by the objective lens 1, the light splitting device 2, the first eyepiece 3 and the first imaging acquisition equipment 4 of the multiple imaging device, and a high-power optical path is formed by the objective lens 1, the light splitting device 2, the second eyepiece 6 and the second imaging acquisition equipment 7, wherein the multiple of the second imaging information acquired by the second imaging acquisition equipment 7 is higher than the multiple of the first imaging information acquired by the first imaging acquisition equipment 4, through the adjustment, the first image information and the second imaging information with different multiples can be acquired, the processing device processes the first image information formed after the first imaging information is acquired by the first imaging acquisition equipment 4, and processes the second image information formed after the second imaging information is acquired by the second imaging acquisition equipment 7, so that the reading operation is realized. Through the arrangement, the switching operation of the high-power objective lens and the low-power objective lens is effectively avoided, and the efficiency of the specimen slide reading device is ensured. And moreover, vibration caused in the process of switching the objective lens is avoided, the imaging effect is ensured, and negative influence on the whole imaging process is avoided. The efficiency of the specimen slide reading device is improved, vibration caused by switching of the objective lens is avoided, and negative influence on the whole imaging process is avoided.

In the specific operation process, a sample is adjusted to move relative to the object lens 1 by using the sample moving control device, and the imaging information of the sample passes through the object lens 1 and then generates the same initial imaging information in a first direction and a second direction respectively; acquiring first imaging information of the initial imaging information in the first direction after passing through a first ocular 3, and acquiring second imaging information of the initial imaging information in the second direction after passing through a second ocular 6; the second imaging information is higher in multiple than the first imaging information.

Preferably, the movement of the specimen by the specimen movement control means may depend on the first imaging information acquired by the first imaging acquisition apparatus 4. The operator uses the sample movement control device to adjust the sample to move relative to the objective lens 1 according to at least the first imaging information acquired by the first imaging acquisition device 4, and determines the region of interest of the sample. That is, it is determined whether the position of the specimen with respect to the objective lens 1 is the region of interest of the specimen by the first imaging information acquired by the first imaging acquisition apparatus 4; if the position of the sample relative to the objective lens 1 is determined to be the region of interest of the sample, the first imaging information acquired by the first imaging acquisition device 4 can be processed by the processing means to form first image information, and the second imaging information acquired by the second imaging acquisition device 7 at the moment can be processed by the processing means to form second image information; if the position of the sample relative to the objective lens 1 is determined not to be the region of interest of the sample, the sample movement control device is required to adjust the movement of the sample relative to the objective lens 1 until the position of the sample relative to the objective lens 1 is determined to be the region of interest of the sample through the first imaging information acquired by the first imaging acquisition device 4, in this state, the first imaging information acquired by the first imaging acquisition device 4 is processed by the processing device to form first image information, and the second imaging information acquired by the second imaging acquisition device 7 at this time is processed by the processing device to form second image information.

Therefore, the basis of the movement of the sample relative to the objective lens 1 by the sample movement control device is the first imaging information acquired by the first imaging acquisition device 4, so that the sample movement control device can be in communication connection with the first imaging acquisition device 4, and the operator can control the sample movement control device according to the first imaging information acquired by the first imaging acquisition device 4, so that the sample movement control device adjusts the movement of the sample relative to the objective lens 1.

Of course, the sample movement control means may also be moved in accordance with the second imaging information acquired by the second imaging acquisition apparatus 7. However, since the second imaging information acquired by the second imaging acquisition device 7 should fall into the region of interest of the sample, and since the multiple of the second imaging information is higher than the multiple of the first imaging information, the difficulty of determining the region of interest of the sample by the second imaging information acquired by the second imaging acquisition device 7 is greater than the difficulty of determining the region of interest of the sample by the first imaging information acquired by the first imaging acquisition device 4.

The region of interest of the sample is a suitable region for the sample in the operation process of the sample reading device, and the suitable region of the sample is determined according to the type of the sample and the requirement of the sample reading operation, which are not described in detail one by one and are all within the protection range.

In a first embodiment, as shown in fig. 1, the objective lens group in the low power optical path is a low power objective lens group, and the objective lens group in the high power optical path is a high power objective lens group. The high power objective lens group further comprises a magnifying lens group 5, and initial imaging information generated in the second direction under the action of the light splitting device 2 passes through the magnifying lens group 5 and then passes through a second ocular lens 6 to form second imaging information. By adding the magnifying lens group 5, the imaging magnification of the second imaging information is increased. In the present embodiment, the magnifications of the first eyepiece 3 and the second eyepiece 6 may be the same or different. It is necessary to ensure that the multiple of the second imaging information obtained by the second imaging obtaining device 7 after the initial imaging information in the second direction passes through the magnifying lens group 5 and the second ocular lens 6 is greater than the multiple of the first imaging information obtained by the first imaging obtaining device 4 after the initial imaging information in the first direction passes through the first ocular lens 3.

In a second embodiment, as shown in fig. 2, the magnification of the first eyepiece 3 is lower than that of the second eyepiece 6. With the arrangement, the magnification of the second imaging information can be higher than that of the first imaging information only through the difference between the first eyepiece 3 and the second eyepiece 6, without adding a magnifying component (such as a magnifying lens group 5) and the structure of the sample reading device is effectively simplified.

In order to improve the general degree of the specimen slide reading device, at least one of the first ocular 3 and the second ocular 6 is a replaceable ocular. Preferably, only the second eyepiece 6 is a replaceable eyepiece and the first eyepiece 3 is a non-replaceable eyepiece. And according to the type of the sample, the film reading requirement and other conditions, the multiple between the first ocular 3 and the second ocular 6 meets the requirement.

Preferably, the first imaging acquisition device 4 and the second imaging acquisition device 7 are cameras; the first image information and the second image information are pictures formed after the camera shoots. The first imaging acquisition apparatus 4 and the second imaging acquisition apparatus 7 may be other apparatuses, such as a drawing apparatus or an imaging apparatus, and the like, without being limited thereto.

In order to improve the compactness and ensure the light splitting effect, the light splitting device 2 is a light splitter. The spectroscopic device 2 may be a component such as a one-to-many optical fiber bundle.

The beam splitter is preferably an achromatic beam splitter. The achromatic spectroscope corrects the chromatic aberration of light of a plurality of wavelengths (such as blue light, green light, red light, and the like), so that the chromatic aberration can be reduced or eliminated, and the imaging effect of the first imaging acquisition device 4 and the second imaging acquisition device 7 can be improved.

In addition, the first eyepiece 3 and the second eyepiece 6 may also adopt an achromatic lens, and the achromatic lens corrects chromatic aberration of light with multiple wavelengths (such as blue light, green light, red light, and the like), so as to further reduce or eliminate chromatic aberration, thereby further improving the imaging effect of the first imaging acquisition device 4 and the second imaging acquisition device 7.

In the specimen interpreting apparatus provided in this embodiment, the objective lens 1 is an objective lens with a magnification, which further improves the imaging magnification. It is also possible to make the objective lens 1 an objective lens without magnification.

To simplify the structure, the first eyepiece 3 and the first image capturing apparatus 4 are located on the imaging path in the first direction. With the arrangement, initial imaging information generated in the first direction after the imaging information of the sample passes through the objective lens 1 can directly pass through the first eyepiece 3 and be acquired by the first imaging acquisition device 4, and a component (such as a reflector and the like) for adjusting the direction is avoided.

As above, the second eyepiece 6 and the second image capturing apparatus 7 are located on the imaging path in the second direction. With the above arrangement, initial imaging information generated in the second direction after the imaging information of the sample passes through the objective lens 1 can directly pass through the second eyepiece 6 (and the magnifying lens group 5) and be acquired by the second imaging acquisition device 7, and components (such as a reflector and the like) for adjusting the direction are avoided.

In this example, the sample is a smear of biological sample.

The biological sample smear can be a blood smear, a spinal fluid smear or a stool smear, etc.

the imaging information of the sample passes through the objective lens 1 and then generates the same initial imaging information in the first direction and the second direction respectively; acquiring first imaging information of the initial imaging information in the first direction after passing through a first ocular 3, and acquiring second imaging information of the initial imaging information in the second direction after passing through a second ocular 6; the multiple of the second imaging information is higher than the multiple of the first imaging information;

adjusting the sample to move relative to the objective lens 1;

and processing first image information formed after the first imaging information is acquired and second image information formed after the second imaging information is acquired.

The invention also provides a sample reading method, wherein the imaging information of the sample passes through the objective lens 1 and then respectively generates the same initial imaging information in the first direction and the second direction, and the multiple of the second imaging information formed after respectively passing through the first ocular lens 3 and the second ocular lens 6 is higher than the multiple of the first imaging information. By adjusting the movement of the specimen relative to the objective lens 1, the region of interest of the specimen can be determined. After the region of interest of the sample can be observed through the first imaging information and/or the second imaging information, and the region of interest of the sample is determined, the first image information formed after the first imaging information is acquired and the second image information formed after the second imaging information is acquired are processed, so that the film reading operation is realized. Through the arrangement, the switching operation of the high-power objective lens and the low-power objective lens is effectively avoided, and the efficiency of the specimen reading device is ensured. And moreover, vibration caused in the process of switching the objective lens is avoided, the imaging effect is ensured, and negative influence on the whole imaging process is avoided.

Further, the movement of the sample relative to the objective lens 1 is adjusted at least according to the first imaging information acquired by the first imaging acquisition device 4, and the region of interest of the sample is determined.

Preferably, the movement of the sample may be dependent on the first imaging information acquired by the first imaging acquisition device 4. The operator determines the region of interest of the specimen by adjusting the movement of the specimen relative to the objective lens 1 at least in accordance with the first imaging information acquired by the first imaging acquisition device 4. That is, it is determined whether the position of the specimen with respect to the objective lens 1 is the region of interest of the specimen by the first imaging information acquired by the first imaging acquisition apparatus 4; if the position of the sample relative to the objective lens 1 is determined to be the region of interest of the sample, the first imaging information acquired by the first imaging acquisition device 4 can be processed by the processing means to form first image information, and the second imaging information acquired by the second imaging acquisition device 7 at the moment can be processed by the processing means to form second image information; if the position of the sample relative to the objective lens 1 is determined not to be the region of interest of the sample, the movement of the sample relative to the objective lens 1 needs to be adjusted until the position of the sample relative to the objective lens 1 is determined to be the region of interest of the sample through the first imaging information acquired by the first imaging acquisition device 4 and then is stopped, in this state, the first imaging information acquired by the first imaging acquisition device 4 is processed by the processing device to form first image information, and the second imaging information acquired by the second imaging acquisition device 7 at this time is processed by the processing device to form second image information.

In the present embodiment, the basis for adjusting the movement of the sample relative to the objective lens 1 is the first imaging information acquired by the first imaging acquisition device 4.

Of course, the movement may also be performed in accordance with the second imaging information pair acquired by the second imaging acquisition apparatus 7. However, since the second imaging information acquired by the second imaging acquisition device 7 should fall into the region of interest of the sample, and since the multiple of the second imaging information is higher than the multiple of the first imaging information, the difficulty of determining the region of interest of the sample by the second imaging information acquired by the second imaging acquisition device 7 is greater than the difficulty of determining the region of interest of the sample by the first imaging information acquired by the first imaging acquisition device 4.

Further, after the region of interest of the sample is determined, second imaging information acquired by the second imaging acquisition device 7 captures the target tissue, and the second imaging acquisition device 7 forms second image information; when the region of interest of the sample is determined, the imaging information acquired by the second imaging acquisition device 7 does not capture the target tissue, and the sample is adjusted to move relative to the objective lens 1 according to the second imaging information acquired by the second imaging acquisition device 7 until the second imaging information acquired by the second imaging acquisition device 7 captures the target tissue, and the second imaging acquisition device 7 forms second image information. By the above adjustment operation, formation of the second image information is further facilitated.

Further, the first image acquisition device 4 forms the first image information when the region of interest of the sample is determined. That is, in this process, the first image acquisition device 4 can be caused to form the first image information regardless of whether the imaging information acquired by the second image acquisition device 7 captures the target tissue. The target tissue may be cells, cell numbers, or the like in a region of interest of the sample.

It is also possible to let the first image information be formed by the first image capturing device 4 after the second image information acquired by the second image capturing device 7 is captured to the target tissue. At this time, the second image information is formed after the second imaging information is acquired by the second imaging acquisition apparatus 7, and at the same time, the first image information is formed after the first imaging information is acquired by the first imaging acquisition apparatus 4.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
