Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a supporting frame and detection equipment for a microfluidic chip. Background Art

[0002] Microfluidic chips are microanalysis systems that integrate sample pretreatment, mixing, reaction, separation and detection into one or more chips. They can replace traditional laboratory work. Microfluidic chips require less sample, are easy to operate, and can accurately complete the entire process from sample preparation to result display in a relatively short period of time, effectively overcoming the experimental errors caused by manual operations in traditional laboratory work. Therefore, microfluidic chips have been increasingly used in chemical analysis, DNA sequencing, protein analysis, single cell analysis, single molecule analysis, food safety, environmental testing and drug screening.

[0003] In the actual testing of samples in hospitals, it often happens that a patient needs to be tested for multiple different items, or that different hospitals may perform different tests for the same symptom.

[0004] Compared with traditional detection methods, the reagents of microfluidic technology are pre-sealed in microfluidic chips. Conventional disc-shaped chips usually have a fixed combination of pre-sealed reagent items for the necessity and convenience of large-scale production. This inevitably leads to the situation that the chip disc cannot be fully adapted to the actual use needs. There will be a patient who needs to test multiple chip discs, which increases the patient's waiting time; at the same time, the excess pre-sealed reagents are not used, which increases the cost and the patient does not receive an effective diagnosis.

[0005] In order to achieve the most reasonable balance point, which can meet the actual needs of patients and the efficiency of large-scale production of manufacturers, different sector chips are needed. Each chip is pre-installed with only a few different projects. According to the needs of different patients, different sector chips are spliced ​​on demand to fully adapt to the diagnosis plan of the patient's personalized needs. For the needs of a single small number of projects, sector chip splicing can also be achieved on the same chip, and multiple patients can be measured at the same time, making the average waiting time for a single person shorter.

[0006] There are two main ways of splicing chips. The first is to splice multiple chips together, and the second is to splice multiple chips together with an external frame. In the first splicing method, when multiple chips are spliced ​​together, a certain overall mechanical strength is required to ensure that they will not fall apart during normal operation. Therefore, some buckles, concave-convex grooves, mortise and tenon structures, etc. that play a role in fixing each other will be designed on the chip. However, these additional designs occupy the effective design space on the chip, resulting in fewer test items per unit area. The second splicing method, that is, the splicing method of the chip external frame, usually adopts a chip-on-lower frame structure to form a three-layer structure of motor tray, splicing frame, and chip. Although this architectural form solves the problem of effective use of space and thickening of self-splicing, at the same time, since the motor inside the instrument also supports the chip from below to generate centrifugal rotation force, on the one hand, the frame may interfere with the motor, and on the other hand, when rotating at high speed, the risk of position displacement of the chip is relatively high, which in turn affects the normal progress and detection effect of the test.

[0007] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only for understanding the background of the concept of the present application and may contain information that does not constitute the prior art. Summary of the invention

[0008] Based on this, it is necessary to provide a supporting frame and detection equipment for a microfluidic chip to address the above problems.

[0009] A microfluidic chip carrying frame, used for carrying a plurality of fan-shaped ring chips, the microfluidic chip carrying frame comprising:

[0010] A support plate, wherein the support plate has a support surface along a thickness direction;

[0011] A fixing column, the fixing column is connected to the middle part of the supporting surface of the supporting plate, a limiting convex rib is provided on the outer peripheral surface of the fixing column, the limiting convex rib is spaced apart from the supporting plate, and the limiting convex rib, the outer side of the fixing column and the supporting surface are surrounded to form a slot;

[0012] A support bar and an outer support ring, wherein the outer support ring is fixed to the support disk through the support bar, the other end of the support bar is connected to the outer support ring, the outer support ring surrounds the support disk along the circumference of the support disk, and the outer support ring is spaced apart from the outer circumference of the support disk, and a plurality of limit posts are provided on the support ring, and the plurality of limit posts are spaced apart along the circumference of the support ring;

[0013] Among them, when the supporting frame carries multiple fan-shaped chips, the card slot is used to clamp the inner ring of the fan-shaped chip, and the limiting column is used to insert into the limiting hole on the outer ring of the fan-shaped chip to limit the movement of the fan-shaped chip.

[0014] The supporting frame of the microfluidic chip mentioned above in the present application can at least achieve the following beneficial effects: multiple fan-shaped ring chips can be carried on the supporting frame, and the inner rings of the multiple fan-shaped ring chips can be inserted into the slots on the fixed columns, and the limiting holes on the outer rings of the multiple fan-shaped ring chips can be sleeved on the limiting columns on the outer support ring, so that the supporting frame limits the movement of the multiple fan-shaped ring chips. When in use, the supporting frame can be turned upside down to connect with the tray of the driving device, and the multiple fan-shaped ring chips are clamped between the tray and the supporting frame, and then the supporting frame and the multiple fan-shaped ring chips thereon can be rotated under the drive of the driving device. Compared with the traditional solution, the driving device and the supporting frame of the present application are farther apart, which can reduce the risk of mutual interference between the two, and the fan-shaped ring chip of the present application is not located above the frame, but is clamped between the tray and the supporting frame, which has a better fixing effect, can prevent the chip from being displaced, and ensure the smooth progress of subsequent detection.

[0015] In one embodiment, the support frame of the microfluidic chip further includes an inner support ring, which is fixed to the support bar and is located between the outer support ring and the support plate. Such a structural setting means that there are more hollow areas between the outer support ring and the inner support ring, and between the inner support ring and the support plate, which can reduce the weight and manufacturing cost of the support frame. Moreover, by adding an inner support ring between the outer support ring and the support plate, the structural strength of the support frame can be ensured to prevent the support bar from deforming. Moreover, the inner support ring can also have a certain supporting effect on the middle part of the chip, making the connection between the chip and the support frame more secure.

[0016] In one embodiment, the limiting convex rib extends in a ring shape along the circumference of the fixing column. If the limiting convex rib is in a ring shape, the clamping groove is also distributed around the circumference of the fixing column, which can ensure that the inner rings of multiple fan-shaped chips have a clamping effect and ensure that the chips are firmly fixed.

[0017] In one embodiment, the number of the support bars is set to be multiple, and the multiple support bars are connected to the outer peripheral surface of the support plate and are evenly spaced along the circumference of the support plate. Such a structural setting can further improve the structural strength of the load-bearing frame and prevent deformation.

[0018] In one embodiment, the outer support ring is also provided with a plurality of partition protrusions, and the plurality of partition protrusions are evenly spaced along the circumference of the outer support ring to separate a plurality of loading areas, and one loading area is used to load one fan-shaped ring chip. The plurality of partition protrusions is equivalent to evenly dividing the space on the bearing frame, so that the bearing area of ​​each fan-shaped ring chip is the same, and the partition protrusions can also play a role in positioning and guiding. When placing the plurality of fan-shaped ring chips on the bearing frame, each fan-shaped ring chip needs to be placed between two adjacent partition protrusions. At this time, the limit column on the outer support ring can just align with the limit hole on the chip and then be inserted into the limit hole.

[0019] In one embodiment, the cross-sectional profile of the separation protrusion is triangular and one corner thereof is aligned with the center of the support plate.

[0020] In one embodiment, the outer support ring is arranged concentrically with the support disk.

[0021] In one embodiment, a plurality of equally spaced limiting posts are provided between any two adjacent separation protrusions in the circumferential direction of the outer support ring. The equally spaced distribution of the plurality of limiting posts can allow the chip to be uniformly stressed.

[0022] In one of the embodiments, at least one of the separation protrusions is provided with a positioning notch, and the positioning notch is used to cooperate with a positioning protrusion on a detection device to perform origin positioning on the supporting frame and the microfluidic chip on the supporting frame.

[0023] In one embodiment, the limiting column is inclined toward the support plate. The inclined limiting column can cooperate with the slot on the support plate to clamp the chip between the limiting column and the slot to ensure that the chip does not fall.

[0024] In one of the embodiments, the limiting column is arranged at an acute angle to the supporting surface of the supporting plate.

[0025] In one of the embodiments, one side of the outer support ring is flush with the support surface of the support plate.

[0026] In one of the embodiments, a positioning notch is provided on the outer peripheral surface of the outer support ring, and the positioning notch is used to cooperate with a positioning protrusion on a detection device to perform origin positioning on the supporting frame and the microfluidic chip on the supporting frame.

[0027] In one embodiment, the fixing column is provided with a mounting hole along its axial direction, and the mounting hole is used for direct or indirect connection with a driving device.

[0028] The present application also provides a detection device, which includes a driving device and a supporting frame of the microfluidic chip as described in any of the above embodiments, wherein the driving device is used to drive the supporting frame of the microfluidic chip to rotate.

[0029] Since the above-mentioned detection device includes the supporting frame of the microfluidic chip described in any of the above-mentioned embodiments, the detection device also includes at least the following beneficial effects: a plurality of fan-shaped chips can be carried on the supporting frame, and the inner rings of the plurality of fan-shaped chips can be inserted into the slots on the fixing columns, and the limiting holes on the outer rings of the plurality of fan-shaped chips can be sleeved on the limiting columns on the outer support ring, so that the supporting frame limits the movement of the plurality of fan-shaped chips. When in use, the supporting frame can be turned upside down to connect with the tray of the driving device, and the plurality of fan-shaped chips are clamped between the tray and the supporting frame, and then the supporting frame and the plurality of fan-shaped chips thereon can be rotated under the drive of the driving device. Compared with the traditional scheme, the driving device of the present application is farther away from the supporting frame, which can reduce the risk of mutual interference between the two, and the fan-shaped chip of the present application is not located above the frame, but is clamped between the tray and the supporting frame, so the fixing effect is better, which can prevent the chip from being displaced, and ensure the smooth progress of subsequent detection.
