Description

Sample sorting structure, sample sorting method and related equipment Technical Field

[0001] The present application relates to the technical field of sample sorting, and in particular to a sample sorting structure, a sorting device, a sample sorting fluid system, a sample culture system, and a sample sorting method. Background Art

[0002] Currently, the separation of samples, such as cells, typically requires a centrifuge. This separation of centrifugation and separation often results in low sorting efficiency, and the desired cells can be mixed with other cells, reducing the effectiveness of testing and treatment. Furthermore, the entire process requires manual intervention, making automation impossible and resulting in high labor costs.

[0003] Furthermore, although there are sorting equipment that can separate while centrifuging, the samples after centrifugation need to be pumped out to different containers through pipelines under the action of pumps. This is because the samples in the centrifugal chamber cannot be completely discharged by relying solely on centrifugal force, and the sample residue is high, which leads to a more complex structure of the centrifugal chamber. In addition, as a consumable material, the centrifugal chamber is relatively expensive.

[0004] In summary, how to improve sample sorting efficiency, increase sample utilization, and reduce costs is an urgent problem to be solved by those skilled in the art.

DETAILED DESCRIPTION

[0104] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are merely for explaining the related application and are not intended to limit the application. The described embodiments are merely a portion of the embodiments of the present application and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art based on the embodiments in the present application without creative effort are intended to fall within the scope of protection of the present application.

[0105] Please refer to Figures 1 to 15. The sample sorting structure 100 in the embodiment of the present application uses a centrifugal and extrusion method to stratify and sort the sample bags to be sorted, thereby improving sorting efficiency and reducing labor costs.

[0106] As shown in FIG. 1 to FIG. 9 , the sample sorting structure 100 includes a centrifugal chamber assembly 101 , a rotary drive assembly 102 , a core shaft 103 , an extrusion platform 104 , and a horizontal push drive assembly 105 .

[0107] Centrifugal chamber assembly 101 includes a centrifugal inner cavity 101a, which provides space for sample bags to be sorted. For example, centrifugal inner cavity 101a is an annular inner cavity to achieve uniform sample stratification. Of course, centrifugal inner cavity 101a can also be configured in other shapes. The sample bags to be sorted are made of disposable plastic film and are inexpensive, suitable for holding samples such as blood.

[0108] The rotary drive assembly 102 drives the centrifugal chamber assembly 101 to rotate, thereby driving the sample bags to be sorted to perform centrifugal motion.

[0109] The core shaft 103 is connected to the centrifugal chamber assembly 101 for synchronous rotation. One end of the core shaft 103 extends into the centrifugal cavity 101a, as shown in Figures 3, 7, and 9, and is movable relative to the centrifugal cavity 101a. Specifically, the rotation axis of the core shaft 103 coincides with the rotation axis of the centrifugal cavity 101a, that is, the core shaft 103 and the centrifugal cavity 101a can rotate synchronously, and the core shaft 103 can also move along the rotation axis of the centrifugal cavity 101a.

[0110] The extrusion platform 104 is located within the centrifugal cavity 101a and is fixed to one end of the core shaft 103 extending into the centrifugal cavity 101a. Specifically, to facilitate assembly and disassembly of the extrusion platform 104 and the core shaft 103, a connecting disc 103b is provided on the core shaft 103. The connecting disc 103b has a through hole for connection to the extrusion platform 104 via fasteners. To facilitate positioning of the extrusion platform 104 and achieve coaxial arrangement of the extrusion platform 104 and the core shaft 103, a receiving groove 104b is provided on the extrusion platform 104 to accommodate the connecting disc 103b. As shown in FIG13 , the shape of the receiving groove 104b matches the shape of the connecting disc 103b.

[0111] In order to reduce the weight of the extrusion platform 104 , at least a section of the cross section of the extrusion platform 104 gradually decreases from the end away from the core shaft 103 to the end close to the core shaft 103 , as shown in FIG13 .

[0112] Of course, as shown in FIG14 , the extrusion platform 104 may also include a first turntable 104 c supporting the sample bag to be sorted and a second turntable 104 d connected to the core shaft 103 , wherein the second turntable 104 d is connected to the bottom end of the first turntable 104 c , and a reinforcing rib 104 e is provided between the first turntable 104 c and the second turntable 104 d .

[0113] The extrusion platform 104 is used to load the sample bags to be sorted and, driven by the core shaft 103, moves toward or away from the end of the centrifugal chamber 101a used to squeeze the sample bags to be sorted. To completely squeeze out the sample from the sample bags to be sorted, the loading end surface of the extrusion platform 104, which holds the sample bags to be sorted, can be arranged parallel to the extrusion end surface of the centrifugal chamber 101a used to squeeze the sample bags to be sorted. Specifically, the loading end surface and the extrusion end surface can both be flat, conical, or have other shapes. As long as the parallel arrangement is achieved, the shape falls within the scope of protection of this application.

[0114] The push drive assembly 105 drives the core shaft 103 to move in the centrifugal cavity 101a along the direction of the rotation axis of the centrifugal cavity 101a. The push drive assembly 105 is rotatably connected to the core shaft 103 to avoid affecting the rotation of the core shaft 103 when pushing the core shaft 103.

[0115] The present application adopts a centrifugal and extrusion method. Centrifugation can separate the samples and separate the target sample from the rest of the samples. The horizontal driving component 105 pushes the core shaft 103 horizontally to achieve complete fit between the extrusion platform 104 and the end face of the centrifugal cavity 101a used to squeeze the sample bag to be sorted, completely squeeze out the sample in the sample bag, and then completely collect the target sample, reducing the possibility of the loss of the target sample causing the detection and treatment to not meet the requirements.

[0116] In some embodiments, the centrifugal chamber assembly 101 includes a centrifugal chamber 101b, wherein the inner cavity of the centrifugal chamber 101b is the centrifugal inner cavity 101a. Specifically, as shown in FIG10 , the centrifugal chamber 101b includes a centrifugal chamber housing 101b-1 and a centrifugal chamber cover 101b-2. One end of the centrifugal chamber housing 101b-1 is open. For ease of description, the orientation shown in FIG2 is used, with the top end of the centrifugal chamber housing 101b-1 open, and the centrifugal chamber cover 101b-2 is disposed over the opening of the centrifugal chamber housing 101b-1. The end of the centrifugal chamber cover 101b-2 facing the centrifugal chamber housing 101b-1 is the extrusion end surface of the centrifugal inner cavity 101a for extruding the sample bag to be sorted.

[0117] In order to facilitate observation of the sorting status in the sample bag to be sorted in the centrifugal chamber 101b, at least a portion of the centrifugal chamber cover 101b-2 is made of transparent material, and the other portion can be made of aluminum, etc., which reduces the weight of the centrifugal chamber cover 101b-2 while ensuring strength.

[0118] To facilitate the removal and placement of sample bags to be sorted, the centrifuge chamber cover 101b-2 can be detachably connected to the centrifuge chamber housing 101b-1. Specifically, the centrifuge chamber cover 101b-2 can be detachably fixed to the centrifuge chamber housing 101b-1 using fasteners such as screws, or the centrifuge chamber cover 101b-2 can be hinged on one side to the centrifuge chamber housing 101b-1 and snap-fitted to the centrifuge chamber housing 101b-1 on the other side.

[0119] As shown in Figure 10, a rotation-limiting protrusion 101b-2a is provided on the edge of the centrifugal chamber cover 101b-2, and a rotation-limiting notch 101b-1a is provided at the top of the centrifugal chamber housing 101b-1 to limit the position of the rotation-limiting protrusion 101b-2a, so as to achieve a stable connection between the centrifugal chamber cover 101b-2 and the centrifugal chamber housing 101b-1. Specifically, there are multiple rotation-limiting protrusions 101b-2a, which are evenly distributed in an annular manner around the circumference of the centrifugal chamber cover 101b-2. Correspondingly, the top of the centrifugal chamber housing 101b-1 is evenly distributed in an annular manner with multiple rotation-limiting notches 101b-1a, and the rotation-limiting notches 101b-1a are arranged in a one-to-one correspondence with the rotation-limiting protrusions 101b-2a.

[0120] To facilitate the connection between the centrifuge chamber cover and the centrifuge chamber housing, a connecting post 101b-2b is provided on either the centrifuge chamber cover 101b-2 or the centrifuge chamber housing 101b-1, with a fastening hole provided on the end surface of the connecting post 101b-2b facing the other, and the other is detachably connected to the connecting post 101b-2b via a fastener. A through hole 104a is provided on the extrusion platform 104 to allow the connecting post 101b-2b to pass through, as shown in Figure 12. For example, the connecting post 101b-2b is installed on the centrifuge chamber cover 101b-2, as shown in Figure 11.

[0121] In order to facilitate the sample bag to be sorted to rotate together with the centrifugal chamber 101b, a limiting through hole is opened on the sample bag to be sorted to allow the connecting column 101b-2b to pass through. The connecting column 101b-2b passes through the limiting through hole on the sample bag to be sorted, so that the sample bag to be sorted can rotate together with the centrifugal chamber 101b.

[0122] It should be noted that the connecting column 101b-2b may not be provided. Specifically, the centrifugal chamber cover 101b-2 and the centrifugal chamber shell 101b-1 are respectively provided with connecting holes, and the two are detachably connected by fasteners such as bolts. The extrusion platform 104 is provided with a through hole 104a for allowing the fastener to pass through, and the fastener can also pass through the limiting through hole on the sample bag to be sorted.

[0123] In some embodiments, in order to facilitate the output of samples in the sample bag to be sorted, the centrifugal chamber 101b also includes a rotary joint 101d, as shown in Figures 7 and 9. The rotary joint 101d is installed on the centrifugal chamber cover 101b-2, one end of which is connected to the outlet of the sample bag to be sorted, and the other end is used for an external output pipeline.

[0124] As shown in Figures 7 and 9, the centrifugal chamber assembly 101 also includes a joint fixing piece 101e and a centrifugal rubber block 101f. The centrifugal rubber block 101f is inserted into the rubber block fixing through hole provided on the centrifugal chamber cover 101b-2, and the centrifugal rubber block 101f is provided with a mounting hole for installing one end of the rotary joint 101d. The centrifugal rubber block 101f is convenient for achieving a sealed connection with the centrifugal chamber cover 101b-2. Specifically, the centrifugal rubber block 101f is coaxially arranged with the centrifugal chamber 101b.

[0125] The sample bag to be sorted in the centrifugal chamber 101b is connected to the rotary joint 101d to output the sample in the sample bag to be sorted.

[0126] The joint fixing part 101e is fixed, and the other end of the rotary joint 101d is installed on the joint fixing part 101e and extends out of the joint fixing part 101e to be connected to the external output pipeline.

[0127] As shown in Figures 6-9, centrifugal chamber assembly 101 also includes a protective cover 101g.
