In the detection heating process, the reagent and the separator are both in liquid state, and the separator is replaced by the detection cavity 9461 under the action of the centrifugal field due to the fact that the specific gravity of the separator is smaller than that of the reagent, so that the reaction and detection are not affected.
In some embodiments, the spacer is loaded into the detection chamber 9461 in a molten state and formed by natural solidification or reduced temperature solidification. When the test is not performed, the separator can be controlled to be in an unmelted state, and the sealed and isolated storage of the reagent can be realized through the separator. When the test is required, the separator is controlled to be in a melted state, for example, by heating the test card 93, so that the separator is melted by heating, at this time, the separator can move out of the test cavity 9461 and flow into the separation cavity 9451 under the action of centrifugal force, and the sample can enter the test cavity 9461, and then the separator is solidified again to seal the mouth of the test cavity 9461, so that a mutual separation seal is formed for the plurality of test cavities 9461, so that the reaction or the test can be performed independently between the test cavities 9461.

For example, the abutting portion 8336 can be placed in the abutting groove 948 to heat the portion of the flow channel 947, so as to avoid condensation of water vapor in the flow channel 947, further reduce influence on subsequent detection process, and improve detection accuracy. In some embodiments, the abutment slot 948 may be omitted.
The isolation layer 95 may be a film-like structure, but other structures are also possible. The isolation layer 95 may be made of a material such as a compacting adhesive, an ultraviolet curing adhesive or an optical grade double sided adhesive, or may be made of a material similar to the main body 94. The isolation layer 95 may be attached to the body 94, and may be specifically sealed and fixed by, for example, ultrasonic welding, laser welding, adhesive sealing, etc., 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 is provided to cover the mouth of the sample chamber 9411. To seal off the loading chamber 9411. When sample addition is desired, the cover 96 can be opened, sample can be added to the sample addition chamber 9411, and the cover 96 can be closed. The cover 96 can block water and ventilate, so that water vapor generated in the heating process can be discharged, and the air pressure in the test card 93 is reduced, so that a good ventilation effect can be ensured, and escape of pollutants such as aerosol and biomolecules generated in the amplification reaction can be blocked, so that pollution to personnel and environment caused by detection is avoided.
When the detection card 93 centrifugally rotates, the sample liquid passes through the sample application chamber 9411 and the flow channel 947. The separator is in a solid state at this time, so that 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 be communicated, and the sample liquid can flow into the detection chamber 9461. Because the specific gravity of the isolator is smaller than that of the reagent, the isolator can be replaced on the reagent under the action of the centrifugal field, the reaction and detection are not affected, and the detection cavity 9461 can be sealed.
Some embodiments of the present application further provide a method for detecting based on the detection card 93. The method can be used in the molecular diagnostic apparatus 100 in the above embodiment. Referring to fig. 53, fig. 53 is a schematic diagram illustrating a usage process of the test card in fig. 50. The specific steps are as follows:
step S5301: the sample application chamber receives a sample.
After the sample is added to the sample-adding chamber 9411, the sample needs to be subjected to a heating pretreatment, and the heating mode may be a metal heating block, a heating air flow, electromagnetic waves (infrared radiation, laser, microwave) or the like. The heating area of the detection card can be the area near the sample loading cavity. The heating process is to raise 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 reduced to a specified temperature, such as 60 ℃.
Step S5302: the test card is rotated by centrifugal force to cause the sample to flow through the flow channel to the test chamber.
And (5) performing centrifugal treatment on the rotation control of the detection card. For example, the rotation direction can be controlled to be clockwise, the rotation speed is more than 1000rpm, and the rotation time is about 10-15s. Through the rotation, the sample liquid can flow from the sample adding cavity to the detection cavity through the flow channel, so that the filling of the sample in the detection cavity can be realized conveniently. And excess sample liquid will enter the waste chamber.
Step S5303: the melting spacer is heated so that the sample flows into the detection chamber and mixes with the reagents in the detection chamber.
Here, it is necessary to heat treat the region near the detection chamber so that the temperature is 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 rotates to displace the spacer with the sample in the detection chamber and seal the inlet end of the detection chamber.
The rotation control is performed again on the detection card. Wherein, the motor can rotate clockwise, the rotation speed is more than 1000rpm, and the rotation time is 10-15s. At this time, due to the rotation of the detection card, the sample enters the detection cavity, the isolator and the aqueous solution in the detection cavity are replaced, and the isolator is transferred to the inlet end of the detection cavity, so that the sealing of each detection cavity is completed. And then changing the motor control parameters to enable the detection card to alternately rotate clockwise and anticlockwise. For example, the test card may be controlled to rotate clockwise at a speed of 3000rpm for 1s, then counter-clockwise at a speed of 3000rpm for 1s, and alternately 10-15 times. The sample in the detection cavity and the reagent can be completely dissolved and mixed by the mode of clockwise and anticlockwise alternating rotation.
Meanwhile, the separator flows to the inlet end of the detection cavity under the action of centrifugal force after being heated and melted, so that the inlet end of the detection cavity is sealed.
Step S5305: the mixed mixture was tested.
In this step, amplification reactions and detection are required. If real-time detection is used, the detection and amplification reaction are performed simultaneously, and if end-point detection is used, the detection is performed after the amplification is completed. Wherein the amplification reaction can be achieved by: heating the vicinity of the detection cavity, and controlling the temperature within the range of 60-75 ℃. After reaching the specified temperature, the amplification reaction is completed by preserving the heat for 30-60min according to the specified requirement.
Next, a procedure for performing a sample test using the molecular diagnostic device 100 and the test card 93 will be described, with the following specific procedures:
the control circuit board 40 performs basic information setting such as the number of samples, the type, the heating temperature, the number of rotations, the operation parameters, etc. by the detection card 93 through the input device. After the basic information is set, the detection of the detection card 93 may be further turned on by the input device.
A test card 93 loaded with a sample.
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 synchronization assembly 1213, so that the pressing plate 50 drives the delivery 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 driver 1212 stops operating after the control circuit board 40 receives the signal from the second limit switch 163.
Under the control of the control circuit board 40, the second driving member 6141 slides the carrying member 62 along the second guide rail 613 to a side away from the first connecting plate 6111 via the lead screw 6142. When the first limit switch 15 is triggered by the shipper 62, e.g., the second limit, the shipper 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 sample is placed at a recess 653 of the shipper 62, such as the receptacle 65. The detection card 93, for example, the mounting portion 941 is placed in the receiving hole 655. The test card 93 is fastened to the second fastening portion 654 of the card holder 65, for example, by the fourth fastening portion 942, thereby completing placement of one test card 93.
The control circuit board 40 scans the image of the information mark on the card holder 65 through the code scanning device 14, judges whether the information mark is the detection card 93 predetermined by the user, and if not, carries out 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, and drives the card holder 65 to rotate, so that the recess 653 of the next detection card 93 reaches a predetermined position, and then the placement of the next detection card 93 is operated.
After the detecting card 93 is placed in the concave portion 653 on the card holder 65, the detecting card 93 is circumferentially and uniformly distributed on the card holder 65. If the number of test cards 93 is insufficient to be circumferentially distributed on the card holder 65, trim cards may be placed in the recess 653 of the card holder 65 so that the trim cards are circumferentially distributed on the card holder 65 along with the test cards 93. The test card 93 is thus placed.
Under the control of the control circuit board 40, the second driving member 6141 slides the carrying member 62 along the second guide rail 613 to the side close to the first connecting plate 6111 via the lead screw 6142. When the shipping member 62, such as the first stop 634, triggers the light sensor 616, the shipping member 62 reaches a predetermined position. The second driving part 6141 stops operation after the control circuit board 40 receives the signal that the light sensor 616 is triggered.
The carriage 61, such as the positioning light generator 615, emits light that is transmitted through the positioning holes 576, 517 to the card holder 65 under the control of the control circuit board 40.
If the light passes through the positioning hole 6522 on the card support 65 again, the light passes through the supporting seat 80, such as the positioning hole 814, and is transmitted to the positioning light receiver 716. The control circuit board 40 will confirm that the test card is in the predetermined position.
If the light cannot pass through the positioning holes 6522 on the card support 65. The positioning light receiver 716 cannot receive the light emitted from 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, and the positioning hole 6522 on the card holder 65 is opposite to the positioning hole 576, and the light passes through the positioning holes 576, 517, 6522 and is received by the positioning light receiver 716. And then proceeds 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 synchronization assembly 1213, so that the pressing plate 50 drives the delivery assembly 60 to slide on the first guide rail 1126 toward the side far from the top plate 111. When the shipper 62, such as the card holder 65, is in quick contact with the support 80, such as the support body 81. The first positioning member 656 of the card support 65 facing the side of the supporting seat main body 81 will extend 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 placed in the second positioning member 813, so as to position the detection card 93.
When the clip 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, for example, the mounting portion 941, is to be placed in the loading chamber setting groove 8332 of the loading chamber mounting seat 833. The detection card 93, e.g. the first mating portion 945, will be placed in the light detecting member 821, e.g. the isolation groove 8224. The detection card 93, for example, the second socket 946, will be placed in the light detecting member 821, for example, the detection groove 8223. The detection card 93, for example, the first limiting portion 943, is disposed in the supporting base body 81, for example, the extending groove 815, and abuts against the mounting table 816. The detection card 93, for example, the second stopper 944 is placed in the support base body 81, for example, the extension groove 815, and abuts against the mounting table 816. To this end, the placement of the detection card 93 on the support base 80 is completed.
When the limit plate 5813 triggers the second limit switch 16, e.g., the first sub-limit switch 162, the pressing plate 50 reaches a predetermined position. The first driver 1212 ceases operation after the control circuit board 40 receives the signal from the first sub-limit switch 162. At this time, the pressing plate 50, for example, the heating element 54, is placed in contact with the detecting card 93 at a position where the isolation chamber 9451 and the detecting chamber 9461 are provided, and the pressing member 53, for example, the abdication portion 5312 and the sub abdication portion 5313 abdies the cover 96 of the detecting card 93 to clamp the cover 96. At the same time, the securing of the pressing piece 53 is released because the locking piece 56 is pressed.
Under the control of the control circuit board 40, the heating devices in the loading chamber assembly 83, for example, the loading chamber mounting seat 833, and the heating devices in the second heating member 542 are heated to complete the heating of the detection card 93, for example, the loading chamber 9411. The heating pretreatment of the sample is realized.
In the presence of the electromagnetic member 52, the electromagnetic force needs to be canceled under the control of the control circuit board 40 so that the pressing member 53 is placed above the card holder 65. Specifically, the pressing member 53, for example, the first clamping portion 5314 is sleeved on the third clamping portion 6521 of the clamping support 65, so that the pressing member 53 and the clamping support 65 are fixed, and in addition, the clamping support 65 is tightly abutted to the pressing member 53 by matching with the acting force generated by the electromagnet, the permanent magnet and the like in the clamping support 65. Without the hold-down member 53, the holding-down member 53 is fixed only by the electromagnetic member 52.
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 synchronization assembly 1213, so that the pressing plate 50 drives the delivery assembly 60 to slide on the first guide rail 1126 towards the side close to 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 driver 1212 stops operating after the control circuit board 40 receives the signal from the second limit switch 163.
Under the control of the control circuit board 40, the third driving member 64 starts to rotate to drive the card holder 65 to rotate, so as to realize the first centrifugal treatment of the detection card. After completion, the repositioning of the test card is achieved by the cooperation of the positioning light generator 615 and the positioning light receiver 716.
The detection card 93 is again fed onto the holder 80, for example, the holder body 81, under the control of the control circuit board 40.
The heating device in the first heating element 541 is controlled to be heated under the control of the control circuit board 40, and the heating device in the photodetection element 821 is controlled to be heated. The secondary heating of the detection card 93 is realized.
The test card 93 is then centrifuged again.
Finally, the test card 93 is transferred to the support 80, for example, the support body 81.
Under the control of the control circuit board 40, the light generator 91 emits excitation light, and the mixture in the detection chamber 9461 of the detection card 93 is excited in the detection groove 8223. The light sensor 9213 in the light receiving member 92 receives fluorescence. The detection signal is received by the control circuit board 40 and processed to form diagnostic data.
