The first lens module 915 is mounted in the first sub-receiving cavity 9131 a. The optical axis of the light source can be the same as that of the light source 914, so that the excitation light emitted from the light source 914 can pass through the optical axis, and the beam of the excitation light can be narrowed and the focal length of the excitation light can be reduced, thereby better coupling the excitation light into the excitation fiber 917. The first lens module 915 may include a first lens 9151, a second lens 9152 having the same optical axis as the first lens 9151, and a first clamping ring 9153 for fixing the first lens 9151 and the second lens 9152.

The lenses, such as the first lens 9151 and the second lens 9152, may be specifically plano-convex lenses. The plano-convex lens is a positive lens and mainly has the functions of beam expanding, imaging, beam collimation, focusing collimation, beam collimation point light source and the like in an optical system. One of the plane-convex lens incidence surface and the plane-convex lens exit surface is a convex surface, and the other plane is a plane.

In one embodiment, the filters 9161 may be excitation filters. The Excitation Filter is also called a fluorescence Excitation Filter (Excitation Filter ), and refers to a Filter through which only light with a wavelength for Exciting fluorescence passes in a fluorescence microscope or a fluorescence imaging system, and it is a matter of course that laser (i.e., laser emitted by the light source 914) is directly used as Excitation light.

The side of the optical filter 9161 remote from the first lens module 915 abuts against the rear case 9132, for example, the rear case main body 9135. One side of the optical filter 9161 close to the first lens module 915, for example, the second lens 9152, abuts against the second fixing ring 9163, so that the optical filter 9161 is fixed to the rear housing 9132.

Test card 93

Next, a detection card will be described, which can be used in the molecular diagnostic apparatus 100 in the above embodiment to perform the detection of the sample loaded on the detection card, and further process the detection card to form the diagnostic data.

Referring to fig. 50, fig. 50 is a schematic structural diagram of a detection card according to an embodiment of the present application. Test card 93 is also referred to as a molecular diagnostic centrifugation test card or test card. The detection card 93 may include a body 94 provided with a sample addition cavity, a flow channel, a waste liquid cavity, an isolation cavity and a detection cavity, an isolation layer 95 covering one side of the body 94, and a cover 96 covering the sample addition cavity of the body 94.

Referring to fig. 50, 51 and 52 together, fig. 51 is a cross-sectional view of the detection card 93 taken along line L-L in fig. 50, and fig. 52 is a schematic perspective view of the detection card 93 in fig. 50. The body 94 is made of a hard material such as plastic or the like. The main body 94 may be made of ABS (Acrylonitrile Butadiene Styrene), PDMS (Polydimethylsiloxane), PC (Polycarbonate), PMMA (Polymethyl methacrylate), PS (General purpose polystyrene), PP (Polypropylene), COC (copolymers of cyclic Olefin), COP (cyclic Olefin Polymer), etc. and may be formed by injection molding, numerical control machine processing, or 3D printing.

The body 94 may be a plate-like structure as a whole. The shape of the fan is roughly a sector, and the fan can be in a sector ring shape, a fan blade shape or a pie shape. For example, the body 94 may be formed as a fan shape having two straight sides and one curved side connected end to end. For example, the body 94 may be formed as a fan-ring shape having a straight edge and an outer circular arc edge, a straight edge, and an inner circular arc edge connected end to end in sequence. Of course, the body 94 may have other shapes, which will not be described in detail.

In one embodiment, the included angle between the two straight lines of the fan-shaped structure of the body 94 may be 40-60 °, the diameter of the inner arc edge may be 10-100 mm, and the diameter of the outer arc edge may be 100-200 mm. By adopting the detection cards 93 with the size structure, at least 6 detection cards can be arranged in the detection plane of the molecular diagnosis device 100 to form a circular surface, so that the at least 6 detection cards 93 can be simultaneously detected, the overall detection efficiency is improved, and the detection requirements of a larger scale can be met.

The body 94 is near the center of the outer arc or near the inner arc and has a mounting portion 941 protruding to a side far from the isolation layer 95. The body 94 is provided with a sample adding cavity 9411 at a position opposite to the mounting portion 941 and close to one side of the isolation layer 95, so as to add a sample at the sample adding cavity 9411. The sample application cavity 9411 is mainly used for pretreatment of a sample (liquid sample), and the pretreatment may include one or more of chemical treatment, thermal treatment, enzymatic treatment, physical separation, and the like. In some embodiments, the volume of sample addition chamber 9411 is substantially 200-. The sample addition cavity 9411 can be preloaded with a dried reagent, and can be air-dried/dried in situ, or can be added as a lyophilized reagent into the sample addition cavity 9411.

The body 94 is provided with a fourth engaging portion 942 at a position away from the isolation layer 95 and close to the outer circular arc edge, so as to cooperate with the carrying component 60, such as the second engaging portion 654. In an embodiment, the fourth fastener 942 may be a protrusion. It can be understood that the positions of the second fastening portion 654 and the fourth fastening portion 942 can be interchanged, and the second fastening portion 654 and the fourth fastening portion 942 can also be fastened and engaged in other manners.

It is to be understood that the names of the "first clamping portion", "second clamping portion", "third clamping portion", "fourth clamping portion", and "clamping portion" may be mutually converted in some embodiments. For example, in one embodiment, "the first trim portion" in the other embodiments is referred to as "the second trim portion", and accordingly, "the second trim portion" in the other embodiments is referred to as "the first trim portion".

The body 94 is provided with a first limiting portion 943 at the edge of one straight line edge close to the outer arc edge and bent towards the side far away from the isolation layer 95, and a second limiting portion 944 at the other straight line edge close to the outer arc edge and protruded towards the side far away from the isolation layer 95. The first position-limiting portion 943 of the body 94 cooperates with the second position-limiting portion 944 to fix the detection card 93, so that the centrifugal processing of the detection card 93 can be smoothly performed, and the body 94 is provided with a waste liquid cavity 9441 at a position close to one side of the isolation layer 95 and opposite to the second position-limiting portion 944. The body 94 is provided with a plurality of plug-in portions along the extending direction of the outer circular arc edge at one side far away from the isolation layer 95 and between the first limiting portion 943 and the second limiting portion 944. Each plug section set may include a first plug section 945 and a second plug section 946. The line between the first inserting part 945 and the second inserting part 946 can pass through the circle center of the outer arc edge. The first mating portion 945 is disposed between the mounting portion 941 and the second mating portion 946. First mating portion 945 and second mating portion 946 are configured to mate with test card test socket 30, such as isolation slot 8224 and test slot 8223.

The body 94 is recessed with an isolation cavity 9451 on a side near the isolation layer 95 and opposite the first plug 945. The isolation cavity 9451 is provided with a fusible isolator. The separator is switchable between a molten state and an unmelted state (typically solid). The separator can be controlled to be in an unmelted state when not being tested by the test card 93, and can prevent the sample from entering the test cavity 9461 (shown in FIG. 52) through the flow channel. In some embodiments, the separator may be a paraffin wax, a microcrystalline wax, a synthetic wax, or a natural wax.

The main body 94 is recessed with a detection cavity 9461 at a side close to the isolation layer 95 and opposite to the second mating member 946. Reagents are disposed in the detection chamber 9461. The isolation chamber 9451 communicates with the detection chamber 9461 on a side adjacent to the isolation layer 95. The insulation within the isolation chamber 9451 may also serve to seal off the reagent to prevent reverse entry of the reagent into the isolation chamber 9451. The reagents are maintained within the detection chamber 9461. When performing a test, the separator can be controlled to be in a molten state, and the sample can enter the detection chamber 9461 through the sample adding chamber 9411 to react with the reagent in the detection chamber 9461, thereby completing the test.

The detection chamber 9461 may be lined with reagents and meltable separators. In some embodiments, the separator may be a paraffin wax, a microcrystalline wax, a synthetic wax, or a natural wax. The insulator is characterized in that the insulator is solid at normal temperature and low temperature, changes into liquid after being heated to specific temperature, and has no inhibition effect on nucleic acid amplification reaction. In some embodiments, the reagents may be dry reagents comprising one or more of primers and DNA (deoxyribonucleic acid) binding dyes, enzymes, magnesium sulfate, potassium chloride, dNTPs (nucleotide triphosphates) used for the amplification reaction. The dry reagent is loaded into the detection chamber 9461 in a liquid state and formed by a drying process, which includes air drying, oven drying, and freeze drying, at a temperature less than the melting temperature of the separator. In the process of detection and heating, the reagent and the separator are both in a liquid state, and because the specific gravity of the separator is smaller than that of the reagent, the separator can be replaced out of the detection cavity 9461 under the action of a centrifugal field, so that the reaction and the detection are not affected.

In some embodiments, the insulator is loaded into the detection chamber 9461 in a molten state and formed by natural solidification or freeze-down. When the reagent is not tested, the separator can be controlled to be in an unmelted state, and the reagent can be stored in a sealed and separated mode through the separator. When the test needs to be performed, the separator can be controlled to be in a melting state, for example, the detection card 93 is heated, so that the separator is heated and melted, at this time, the separator can be moved out of the detection cavity 9461 and flow to the separation cavity 9451 under the action of centrifugal force, the sample can enter the detection cavity 9461, and then the separator is solidified again, so as to plug the mouth of the detection cavity 9461, and further form mutual isolation seal for the detection cavities 9461, so that the reaction or the test can be performed between the detection cavities 9461 independently.

The main body 94 is provided with a flow channel 947 on a side close to the isolation layer 95 to communicate the sample-adding chamber 9411 with the isolation chamber 9451.

The body 94 is provided with an abutting groove 948 at a position opposite to the flow passage 947 on a side away from the isolation layer 95 so as to be engaged with the abutting portion 8336. For example, the abutting portion 8336 may be disposed in the abutting groove 948 to heat the portion of the flow channel 947, so as to prevent water vapor from condensing in the flow channel 947, thereby reducing the influence on the subsequent detection process and improving the detection accuracy. In some embodiments, the abutment groove 948 may be omitted.

The isolation layer 95 may have a film-like structure, but may have other structures. The isolation layer 95 may be made of a material such as a compression adhesive, an ultraviolet light curable adhesive, or an optical double-sided adhesive, or may be made of a material similar to the body 94. The isolation layer 95 can be attached to the body 94, and can be specifically fixed in a sealing manner by, for example, ultrasonic welding, laser welding, adhesive sealing, or the like, so as to isolate the flow channel 947, the waste liquid chamber 9441, the isolation chamber 9451, and the detection chamber 9461.

The lid 96 covers the opening of the sample addition chamber 9411. To seal off the sample application chamber 9411. When a sample needs to be added, the cover 96 can be opened, the sample can be added to the sample addition cavity 9411, and then the cover 96 can be closed. The cover 96 is water-resistant and air-permeable, i.e., can discharge the water vapor generated in the heating process, reduce the air pressure in the test card 93, thereby ensuring good air-permeable effect, and can prevent the escape of pollutants such as aerosol, biomolecules and the like generated in the amplification reaction, thereby avoiding the pollution of detection to personnel and environment.

When the detection card 93 is rotated centrifugally, the sample liquid passes through the sample addition chamber 9411 and the flow channel 947. At this time, the separator is in a solid state, whereby the detection chamber 9461 can be sealed, and the sample liquid cannot flow to the detection chamber 9461. After the sample liquid is heated, the separator is melted by heat and flows to the detection chamber 9461, so that the flow channel 947 and the detection chamber 9461 can communicate with each other, and the sample liquid can flow into the detection chamber 9461. Because the specific gravity of the separator is less than that of the reagent, the separator can be displaced onto the reagent under the action of the centrifugal field, so that the reaction and detection are not affected, and the detection cavity 9461 can be sealed at the same time.

Some embodiments of the present application further provide a method for detecting based on the above-mentioned detection card 93. This method can be used in the molecular diagnostic apparatus 100 in the above-described embodiment. Referring to fig. 53, fig. 53 is a schematic diagram illustrating a using process of the detection card in fig. 50. The specific steps can be as follows:

step S5301: the sample application chamber receives a sample.

After the sample is added to the sample adding cavity 9411, the sample needs to be heated and pretreated, and the heating mode can be a metal heating block, a heating airflow, an electromagnetic wave (infrared radiation, laser, microwave) or the like. The heating region of the test card can be the region near the sample application chamber. The heating process is carried out by raising the temperature to a specified temperature, such as 90 ℃. And after reaching the specified temperature, preserving heat for 3-10min according to the specified requirement to realize pretreatment. After the pretreatment is completed, the temperature of the sample liquid is lowered to a prescribed temperature, for example, 60 ℃.

Step S5302: the detection card is rotated by centrifugal force to cause the sample to flow through the flow channel to the detection chamber.

And carrying out centrifugal processing on the rotation control of the detection card. For example, the direction of rotation may be controlled to be clockwise, the rotation speed greater than 1000rpm, and the rotation time about 10-15 s. Through rotation, the sample liquid can flow to the detection cavity from the sample adding cavity through the flow channel, so that the filling of the sample in the detection cavity can be realized conveniently. And excess sample fluid will enter the waste chamber.

Step S5303: the heating melts the separator to cause the sample to flow into the detection chamber and mix with the reagent in the detection chamber.

It is necessary to heat the region near the detection chamber to a temperature higher than the melting point of the separator, thereby melting the separator and mixing the sample with the reagent in the detection chamber.

Step S5304: the centrifuge is rotated to displace the separator with the sample in the detection chamber and seal the inlet end of the detection chamber.

The rotation of the detection card is controlled again. Wherein, the motor can rotate along the clockwise direction, the rotating speed is more than 1000rpm, and the rotating time is 10-15 s. At this moment, because the rotation of detection card for the sample gets into and detects the intracavity, and the insulator takes place the replacement with the aqueous solution that detects the intracavity, and the insulator shifts to the entry end that detects the chamber, thereby accomplishes the sealed of each detection chamber. And then changing the control parameters of the motor to enable the detection card to rotate clockwise and anticlockwise alternately. For example, the card may be controlled to rotate clockwise at 3000rpm for 1s and then rotate counterclockwise at 3000rpm for 1s, with 10-15 rotations alternated. The sample and the reagent in the detection cavity can be completely mixed, dissolved and mixed by the clockwise and anticlockwise alternate rotation mode.

Meanwhile, the isolating body flows to the inlet end of the detection cavity under the action of centrifugal force after being heated and melted so as to seal the inlet end of the detection cavity.

Step S5305: and detecting the mixed mixture.

In this step, an amplification reaction and detection are required. If real-time detection is used, detection and amplification reactions are performed simultaneously, and if endpoint detection is used, detection is performed after amplification is complete. Wherein, the amplification reaction can be realized by the following modes: heating the vicinity of the detection cavity, and controlling the temperature to be within the range of 60-75 ℃. After reaching the specified temperature, the amplification reaction is finished by heat preservation for 30-60min according to the specified requirements.

The following describes a process of performing a sample test using the molecular diagnostic apparatus 100 and the test card 93, and the specific process is as follows:

the control circuit board 40 performs basic information setting such as the number, type, heating temperature, number of rotation revolutions, operation parameters, etc. of the samples detected by the detection card 93 through an input device. After the basic information is set, the detection of the detection card 93 may be further started through an input device.

A test card 93 loaded with a sample.

Under the control of the control circuit board 40, the first driving unit 1212 respectively controls the first lead screw 1221 and the second lead screw 1222 to rotate through the synchronization assembly 1213, so that the pressing disc 50 drives the carrying assembly 60 to slide on the first guide rail 1126 toward the top plate 111. When the limit plate 5813 triggers the second limit switch 16, for example, the second sub-limit switch 163, the pressing plate 50 reaches a predetermined position. The first driving unit 1212 stops operating when the control circuit board 40 receives a signal that the second sub-limit switch 163 is triggered.

Under the control of the control circuit board 40, the second driving member 6141 slides the carrying member 62 along the second guiding rail 613 to the side away from the first connecting plate 6111 through the lead screw 6142. When the carrying member 62, for example, the second limit member, triggers the first limit switch 15, the carrying member 62 reaches a predetermined position. The second driving member 6141 stops operating after the control circuit board 40 receives the signal that the first limit switch 15 is triggered.

The test card 93 loaded with the sample is placed at the recess 653 of the carrier 62, e.g., the card holder 65. The detection card 93, for example, the mounting portion 941 is disposed in the accommodation hole 655. The detection card 93, for example, the fourth fastening portion 942 is fastened to the second fastening portion 654 of the card holder 65, and the placement of one detection card 93 is completed.

The control circuit board 40 scans the information identifier on the card holder 65 through the code scanning device 14, and determines whether the information identifier is a detection card 93 predetermined by the user, and if not, performs an early warning prompt. If yes, the next step is carried out.

Under the control of the control circuit board 40, the third driving member 64 starts to rotate, which drives the card holder 65 to rotate, so that the recess 653 where the next test card 93 can be placed reaches a predetermined position, and then the placement of the next test card 93 is operated.

After the detection cards 93 are placed in the recesses 653 on the card holder 65, the detection cards 93 are circumferentially and uniformly distributed on the card holder 65. If the number of test cards 93 is not sufficient to be circumferentially disposed on the card support 65, the leveling cards can be placed in the recesses 653 of the card support 65 such that the leveling cards are circumferentially disposed on the card support 65 along with the test cards 93. This completes the placement of the test card 93.

Under the control of the control circuit board 40, the second driving member 6141 slides the carrying member 62 along the second guiding rail 613 to the side close to the first connecting plate 6111 through the lead screw 6142. When a shipping article 62, such as first stop 634, triggers light sensor 616, shipping article 62 reaches a predetermined position. The second driving member 6141 stops operating after the control circuit board 40 receives the signal triggered by the optical sensor 616.

The carriage 61, for example, the positioning light generator 615 emits light under the control of the control circuit board 40, and the light is transmitted to the card holder 65 through the positioning holes 576 and 517.

If the light passes through the positioning hole 6522 of the card holder 65 again, the light is directly transmitted to the positioning light receiver 716 through the supporting base 80, such as the positioning hole 814. The control circuit board 40 will confirm that the detection card is at the predetermined position.

If the light cannot pass through the positioning hole 6522 of the card holder 65. The positioning light receiver 716 cannot receive light generated by the positioning light generator 615. The control circuit board 40 controls the third driving member 64, so that the third driving member 64 drives the card holder 65 to rotate, the positioning holes 6522 and the positioning holes 576 on the card holder 65 are disposed opposite to each other, and the light passes through the positioning holes 576, 517 and 6522, and is received by the positioning light receiver 716. And then proceed to the next step.

Under the control of the control circuit board 40, the first driving element 1212 respectively controls the first lead screw 1221 and the second lead screw 1222 to rotate through the synchronizing assembly 1213, so that the pressing plate 50 drives the carrying assembly 60 to slide on the first guide rail 1126 to the side away from the top plate 111. When the carrier 62, such as the retainer 65, comes into contact with the support 80, such as the support body 81. The first positioning member 656 on the side of the card holder 65 facing the support seat main body 81 extends into the second positioning member 813, and due to the special structure of the first positioning member 656, the first positioning member 656 is easily arranged in the second positioning member 813, so that the detection card 93 is positioned.

When the retainer 65 abuts against the support base 80, for example, the support base main body 81. The test card 93 will be positioned on the support base 80. The detection card 93 is placed in the sample chamber placement groove 8332 of the sample chamber holder 833, for example, in the mounting portion 941. The test card 93, e.g., first socket 945, will be placed in the light detector 821, e.g., isolation slot 8224. The test card 93, such as the second mating member 946, will be placed in the light detector 821, such as the test slot 8223. The detection card 93, for example, the first stopper 943 is placed in the support base body 81, for example, the extension groove 815, and abuts against the mounting base 816. The detection card 93, for example, the second stopper portion 944, is placed in the support base body 81, for example, the extension groove 815, and abuts against the mounting stand 816.
