Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart of an embodiment of a method for detecting an in vitro diagnostic apparatus provided in the present application, the method including:
step 11: and acquiring a detection image acquired by the image acquisition unit.
The in vitro diagnostic device can be an immunoassay analyzer, a blood globe apparatus and the like, and is used for detecting blood, body fluid, tissues and the like. Alternatively, taking an immunoassay analyzer as an example, the in-vitro diagnostic apparatus may include a sample injection mechanism, a reaction mechanism, an incubation mechanism, a detection mechanism, and the like, and a pipeline (a liquid path or a gas path) connecting the above various mechanisms.
It will be appreciated that the extracorporeal diagnostic apparatus comprises a housing within which at least part of the mechanism described above is disposed.
In this embodiment, the image capturing unit is disposed inside the housing and is used for capturing a detection image inside the in-vitro diagnostic apparatus.
Step 12: and comparing the detection image with a preset standard image to determine the use condition of the in-vitro diagnosis equipment.
The preset standard image is obtained by acquiring an image inside the in-vitro diagnostic equipment when the in-vitro diagnostic equipment leaves a factory. It is noted that the preset standard image and the detection image are acquired by the same image acquisition unit.
Optionally, in an embodiment, the external diagnostic apparatus stores the preset standard image therein, and the diagnostic apparatus compares the detection image with the preset standard image to determine the usage of the external diagnostic apparatus. It is understood that the area of the storage medium in which the preset standard image is stored is an unmodified area.
Optionally, in another embodiment, the in-vitro diagnostic apparatus sends the detection image to the server, so that the server compares the detection image with a preset standard image to determine the use condition of the in-vitro diagnostic apparatus; and then receiving the use condition sent by the server.
Specifically, a communication unit, such as a cellular communication module, a WIFI module, a wired network (e.g., an optical fiber), etc., may be disposed in the in-vitro diagnostic apparatus, and the detected image is sent to the server through the network.
It is understood that the server processes the detected image in a manner similar to that of the in-vitro diagnostic apparatus in the above-described embodiment. In one embodiment, the server stores the preset standard image therein, and the server compares the detection image with the preset standard image to determine the use condition of the in-vitro diagnostic apparatus. It is understood that the area of the server where the preset standard image is stored is an unmodified area.
Specifically, for a specific manner of image comparison, the following embodiments may be referred to. Referring to fig. 2, fig. 2 is a schematic flow chart of step 12 in fig. 1, where step 12 may specifically include:
step 121: and performing edge extraction on the detection image to determine a pipeline area and/or a background area.
It can be understood that, since the extracorporeal diagnosis apparatus includes a large number of pipelines, it is an effective way to detect whether the extracorporeal diagnosis apparatus is disassembled by detecting whether the pipelines are changed. It should be noted that the line detection is only an optional embodiment, and in other embodiments, other structures inside the in-vitro diagnostic apparatus may be detected.
Alternatively, in an embodiment, the edge extraction may include binarization processing. Since the pipeline is generally made of transparent material and the reagent flowing inside the pipeline is also transparent, the detection image can be subjected to binarization processing, wherein a background area is formed by a low pixel value and a foreground area (pipeline area) is formed by a high pixel value.
In addition, in other embodiments, a deep learning model, such as an image segmentation model, may also be used for edge extraction.
Optionally, since the pipeline may have a small deviation in position during transportation of the in-vitro diagnostic apparatus, after the edge extraction, the image expansion processing may be performed on the pipeline region to avoid a misjudgment in the subsequent image comparison process.
Step 122: and respectively comparing the pipeline area and/or the background area with a preset standard image.
For the preset standard image, edge extraction can be performed in the same manner as described above to form a standard pipeline region and a standard background region. Then the target pipeline area is compared with the standard pipeline area, and the target background area is compared with the standard background area.
Step 123: and determining the use condition of the in-vitro diagnosis equipment according to the comparison result of the pipeline region and the preset standard image and/or the comparison result of the background region and the preset standard image.
Wherein for the pipe section a comparison of the position changes can be made.
The following is presented in two specific ways:
the first method comprises the following steps:
carrying out binarization processing on the detection image to determine a target pipeline area; and carrying out binarization processing on the preset standard image to determine a standard pipeline area.
Carrying out pixel value difference processing on the target pipeline area and the standard pipeline area to obtain a difference value area; and determining that the in-vitro diagnostic device is illegally used in response to the area of the difference region being larger than the set area threshold.
It is to be understood that, after the binarization processing is performed on the image, the pipeline region is determined to be the minimum value "0", the background region is determined to be the maximum value "1", and then the pixel value difference processing is performed on the target pipeline region and the standard pipeline region, wherein the difference value is 0 in the case of "0-0" and "1-1" and indicates the same region, and the difference value is 1 or-1 in the case of "0-1" and "1-0" and indicates different regions, and then the extracorporeal diagnosis device can be determined to be illegally used according to the fact that the area of the region whose difference value is not 0 is larger than the set area threshold.
And the second method comprises the following steps:
carrying out binarization processing on the detection image to determine a target pipeline area; and carrying out binarization processing on the preset standard image to determine a standard pipeline area.
Carrying out image corrosion treatment on the target pipeline area to obtain a first pipeline track; performing image corrosion treatment on the standard pipeline area to obtain a second pipeline track; determining a distance between the first and second pipeline trajectories; and determining that the in-vitro diagnostic device is illegally used in response to the distance between the first pipeline track and the second pipeline track being greater than a set distance threshold.
The etching treatment may specifically include: firstly, carrying out image expansion processing on the pipeline area to reduce the influence caused by slight shaking of the equipment, and then carrying out image corrosion processing (such as skeleton extraction) on the pipeline area to obtain a pipeline track.
When the distance calculation is performed, one or more reference points can be selected on the target pipeline track and the standard pipeline track respectively, and the distance between the reference points on the two tracks can be calculated. Specifically, at least one first reference point on a first pipeline track is determined; and determining at least one second reference point on the second pipeline trajectory; the first reference points correspond to the second reference points one by one, and the lengths of the corresponding first reference points and the second reference points along the pipeline track are the same; determining the distance between the first reference point and the second reference point which correspond to each other one by one.
For example, determining reference point O1 at the end point of the target pipeline track, determining reference points A1, B1, C1 … … along the pipeline track starting from O1, determining reference point O2 (corresponding to O1) at the end point of the standard pipeline track, determining reference points A2, B2, C2 … … along the pipeline track starting from O2 it is noted that upon selection of the reference points, the distance between O1-A1 is equal to the distance between O2-A2, the distance between A1-B1 is equal to the distance between A2-B2, and so on.
Then, by selecting the reference points, the distance between a1 and a2, the distance between B1 and B2, and the distance … … between C1 and C2 can be calculated respectively, in one embodiment, when any one of the distances is greater than a set distance threshold, the external diagnostic device can be determined to be illegally used, in another embodiment, the distances can be weighted and summed, and when the weighted and summed value is greater than the set distance threshold, the external diagnostic device can be determined to be illegally used.
It will be appreciated that the selection of the reference point may be performed by selecting only one point, and selecting the reference point as far as possible from the two end points.
It will be appreciated that the color of the tubing may not be detected because the liquid or gas introduced into the tubing may be different or bubbles may be present in the liquid in the tubing, and therefore, the pixel values in the tubing regions may not be compared when performing the above comparison.
Wherein for the background area a comparison of the color change can be made.
Optionally, in response to that the distribution similarity or the color similarity between the target background region and the standard background region in the preset standard image is smaller than a set threshold, determining that the in-vitro diagnostic apparatus is illegally used.
Specifically, since the acquired detection image and the preset standard image are acquired by the same image acquisition unit at the same position, the position range of the target background region in the detection image and the position range of the standard background region in the preset standard image can be determined respectively, and then the position distributions of the two are compared. For example, the detection image and the preset standard image may be overlapped, then the ratio of the overlapping range of the target background region and the standard background region to the whole background region is compared, and then it is determined whether the ratio is greater than a set ratio (for example, 90%), if so, the distribution similarity between the target background region and the standard background region in the preset standard image is considered to be greater than a second set threshold, otherwise, the distribution similarity between the target background region and the standard background region in the preset standard image is considered to be less than the second set threshold.
Specifically, the pixel value of each pixel point in the detection image of the target background region and the pixel value of each pixel point in the standard background region may be respectively determined, and then whether the pixel values of the same pixel point in the detection image and the preset standard image are the same (or close) is determined, and then whether all the pixel points are in the same proportion is determined. For example, the pixel value of x pixels in the target background region is the same as or close to the pixel value of the same pixel in the standard background region (the difference between the pixel values is smaller than the set threshold), the pixel value of y pixels is different from the pixel value of the same pixel in the standard background region (the difference between the pixel values is larger than the set threshold), and then it is determined whether x/(x + y) is larger than the set proportion (e.g., 90%), if so, the color similarity between the target background region and the standard background region in the preset standard image is considered to be larger than the second set threshold, otherwise, the color similarity between the target background region and the standard background region in the preset standard image is considered to be smaller than the second set threshold.
Step 13: and correspondingly processing the in-vitro diagnosis equipment according to the use condition.
Optionally, the processing method herein may include stopping, not stopping but not outputting the result, not stopping but prompting the machine to be in a quality control runaway state, warning, remote warning, and the like, and combinations thereof.
The "shutdown" means that the in-vitro diagnostic apparatus is directly powered off from a power-on state, or cannot be powered on again in the power-off state.
The term "does not stop but does not output the result" means that the detection can be continued but the detection result is not output; or the detection result is uploaded to the server and not displayed locally, and the user can obtain the response detection result only by contacting with the staff at the server end.
The "not stopping but prompting that the machine is in a quality control out-of-control state" means that the detection can be continued, but the re-doing of the quality control and calibration process is prompted, and the quality control and calibration process needs a higher-level authorization.
The "warning" refers to continuing the alarm reminding directly by sound, light, or the like, for example, flashing the screen and sounding an alarm.
The term "remote warning" refers to sending alarm information to the server to inform the server of the illegal use condition of the diagnostic equipment locally.
Different from the prior art, the in-vitro diagnostic apparatus provided in this embodiment includes a housing and an image capturing unit disposed in the housing, and the detection method of the in-vitro diagnostic apparatus includes: acquiring a detection image acquired by an image acquisition unit; comparing the detection image with a preset standard image to determine the use condition of the in-vitro diagnostic equipment; and correspondingly processing the in-vitro diagnosis equipment according to the use condition. By the mode, the structural change condition in the in-vitro diagnostic equipment can be detected by adopting an image recognition mode, so that the condition that the in-vitro diagnostic equipment is disassembled, modified and deformed in an illegal mode is avoided, and for the in-vitro diagnostic equipment closely related to human health, the precision and the detection accuracy of an instrument can be ensured by adopting the mode on one hand, and on the other hand, the instrument can be prevented from being counterfeited.
Referring to fig. 3, fig. 3 is a schematic flow chart of another embodiment of the detection method of the in-vitro diagnostic apparatus provided by the present application, the method includes:
step 31: the state of the housing is detected.
It is to be understood that the purpose of detecting the state of the housing in this step is to detect whether the extracorporeal diagnostic apparatus, which is generally a closed apparatus, is disassembled, and to see the internal structure thereof, the housing thereof needs to be disassembled.
Optionally, in an embodiment, a maintenance window is disposed on the housing of the extracorporeal diagnosis apparatus, and a lock, which may be a physical lock or other coded lock, such as a fingerprint lock, is disposed on the maintenance window and needs to be opened by a professional.
In this case, a detection means, such as an infrared sensor, may be provided at the window opening position, and when the serial port is opened in an illegal manner, the infrared sensor detects that the window is opened.
Alternatively, in another embodiment, since the in-vitro diagnostic apparatus is a sealed structure, the light inside the in-vitro diagnostic apparatus is dark, so that the in-vitro diagnostic apparatus can detect the light by using the light sensor, when the housing is opened, the light enters, and the brightness inside the in-vitro diagnostic apparatus suddenly changes, and the light sensor detects the brightness change, so that the housing is determined to be opened.
It is understood that the above two methods are only examples, and other hardware (e.g. mechanical, optical, electrical) or software methods can be used for detection.
Step 32: and triggering the image acquisition unit to acquire the detection image in response to the state transmission change of the shell.
Step 33: and comparing the detection image with a preset standard image to determine the use condition of the in-vitro diagnosis equipment.
Step 34: and correspondingly processing the in-vitro diagnosis equipment according to the use condition.
The above steps 32-34 are similar to the above embodiments and will not be described again.
In addition, on the basis of the two embodiments, the following detection modes can be added:
in one embodiment, position information of an extracorporeal diagnosis apparatus is acquired; and responding to the situation that the position information does not meet the preset position range, and carrying out corresponding processing on the in-vitro diagnosis equipment.
Specifically, a positioning unit, such as a GPS positioning module, a positioning antenna, or the like, may be provided in the in-vitro diagnostic apparatus. In general, in vitro diagnostic apparatuses are permitted to be used only in professional places such as hospitals, health centers, and research institutes, as professional apparatuses. If the detected position and the detected position meet the preset range or route, corresponding processing can be carried out, such as means and combination of stopping, stopping but not outputting the result, stopping but prompting that the machine is in a quality control out-of-control state, warning, remote warning and the like.
In another embodiment, input identity information is obtained; verifying the identity information; and responding to the failure of the identity information verification, and performing corresponding processing on the in-vitro diagnosis equipment.
Specifically, the identity recognition mode may include a soft key (account password), a hard key (ukey, a mobile phone terminal, and the like), and a biometric recognition (face, fingerprint, pupil, and the like). Wherein the soft password comprises: the password with corresponding authority is required to be input before the startup, shutdown, quality control process and calibration process; the hard password includes: the ukey authorization is used before each use, and the ukey can also be integrated on a quality control device or a calibration device (such as card swiping calibration), and the authorization operation is completed at the same time when the quality control or calibration process or the calibration process is completed. In addition, the mobile phone of the user can be used as auxiliary authorization (including passwords and wireless positioning of the mobile phone), such as the GPS address of the authorized mobile phone and the GPS address of the diagnostic equipment, and the distance between the two is within a certain range, so that the use is allowed.
It can be understood that, when the authentication is combined with the embodiment of comparing the detection images, if the user identification information corresponds to a higher use authority, such as a maintenance person, the corresponding processing may not be performed even if the external diagnostic apparatus is determined to be used illegally by using the comparison of the detection images.
Optionally, at least a portion of the positioning unit, the identity recognition unit, the image acquisition unit, the communication unit, and the like in the above embodiments are integrated on a main board of the in-vitro diagnostic apparatus, and cannot be detached. The units can communicate in a heartbeat mode, and detection is kept for a long time; after each detection process (each detection measures one sample, all samples on one test tube rack or a batch of test tube racks), the identity recognition unit and the positioning unit or the communication unit are communicated once, so that normal authorization is ensured.
