Detailed Implementation

[0018] The embodiments of the present invention will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0019] This invention provides, for example Figs. 1-2A compact sample analyzer is shown, including a main frame, and a sample rack conveying module 10, an empty cup conveying module 20, a reaction cup incubation disc 30, a reagent refrigeration bin 40, a detection module 50, a first transfer needle module 61, a second transfer needle module 62, a third transfer needle module 63, a cup grabbing module arranged on the main frame. The reaction cup incubation disc 30 surrounds the reagent refrigeration bin 40 and is rotationally connected with the main frame. The sample rack conveying module 10 conveys a sample rack to a sampling position. The first transfer needle module 61 samples blood samples and sends them into reaction cups arranged on the reaction cup incubation disc 30 for incubation. The reagent refrigeration bin 40 is used for refrigerating liquid reagents, diluents, cleaning liquids and the like required for detection. The first transfer needle module 61, the second transfer needle module 62 and the third transfer needle module 63 transfer various reagents required for detection from the reagent refrigeration bin 40 to the reaction cups. After incubation, the cups are sent to the detection module 50 by the cup grabbing module for detection. The empty cup conveying module 20 conveys empty reaction cups to the inside of the sample analyzer. The cup grabbing module is used to grab the reaction cups and move them between the above-mentioned modules. The structures of the above-mentioned modules can be referred to the relevant modules disclosed in the patent documents with publication numbers CN215910503U or CN108535503A, and the above-mentioned modules should be installed as compact as possible on the basis of layout and function implementation.

[0020] In the present application, without reducing the processing capacity of the sample rack conveying module 10, the reaction cup incubation disc 30, the reagent refrigeration bin 40, the magnetic bead detection module 52, the optical detection module 53 and the like, the layout of most modules is redesigned, especially the layout of the empty cup input track 21, the first transfer needle module 61, the second transfer needle module 62, the third transfer needle module 63 and the cup grabbing module which are high-frequency moving modules inside the sample analyzer. This not only guarantees the detection capacity of the sample analyzer, but also reduces the overall size of the machine. Compared with the same processing capacity sample analyzer in the prior art, the overall size of the machine can be reduced by 10-15%.

[0021] Specifically, the sample rack conveying module 10 is arranged on one side of the main frame. The first transfer needle module 61 and the second transfer needle module 62 are arranged between the sample rack conveying module 10 and the reaction cup incubation disc 30, and the first transfer needle module 61 and the second transfer needle module 62 are arranged on both sides of the reaction cup incubation disc 30, respectively. The first transfer needle module 61 is close to the sample rack conveying module 10, which is convenient for sampling. The second transfer needle module 62 avoids the activity range of the first transfer needle module 61, so that they do not affect each other.

[0022] Further, the first transfer needle module 61 and the second transfer needle module 62 each include a needle tube 611, a rotating driving device for driving the needle tube 611 and making the projection of the moving trajectory of the needle tube on the horizontal plane circular, and an up-down driving device for driving the needle tube 611 to move up and down. The structures of the needle tube 611, the rotating driving device, and the up-down driving device can refer to the blood sample analyzer disclosed in CN215910503U. The moving trajectory of the needle tube 611 of the first transfer needle module 61 covers the sample rack conveying module 10, the reaction cup incubation disc 30, and the reagent refrigeration bin 40, so as to complete the transfer of the sample from the sample tube in the sample rack conveying module 10 to the reaction cup in the reaction cup incubation disc 30, and at the same time, the reagent in the reagent bottle in the reagent refrigeration bin 40 can be sucked into the reaction cup in the reaction cup incubation disc 30, or other liquid can be sucked from the reagent refrigeration bin 40. The moving trajectory of the needle tube 611 of the second transfer needle module 62 covers the reaction cup incubation disc 30 and the reagent refrigeration bin 40, so as to suck the reagent in the reagent refrigeration bin 40 into the reaction cup in the reaction cup incubation disc 30 or suck other liquid from the reagent refrigeration bin 40.

[0023] Specifically, the detection module 50 includes a bottom plate 51 arranged on the side of the reaction cup incubation disc 30 away from the sample rack conveying module 10. The side of the bottom plate 51 facing the reaction cup incubation disc 30 is provided with a magnetic bead detection module 52 and a first mixing device 54, and the other side is provided with an optical detection module 53. The empty cup conveying module 20 includes an empty cup input track 21, one end of which extends to between the reaction cup incubation disc 30 and the first mixing device 54. The cup grabbing module and the third transfer needle module 63 each include a transverse track 71 and a longitudinal track 72. The transverse track 71 of the cup grabbing module extends from above the reaction cup incubation disc 30 to above the optical detection module 53, and the transverse track 71 of the third transfer needle module 63 extends from above the reagent refrigeration bin 40 to above the bottom plate 51.

[0024] The magnetic bead detection module 52, optical detection module 53, and first mixer 54 for uniformly mixing multiple liquids in the reaction cup before detection are integrated on the base plate 51 to form the main structure of the detection module 50, which is convenient for installation. The cup gripping module and empty cup input track 21 are also integrated near the detection module 50. The horizontal track 71 of the cup gripping module extends from above the reaction cup incubation plate 30 to above the optical detection module 53, and is equipped with a sufficiently long vertical track so that the movement range of the cup gripping module covers the magnetic bead detection module 52, optical detection module 53, first mixer 54, empty cup input track 21, and reaction cup incubation plate 30. The process of transferring the empty reaction cup from the empty cup input track 21 to the reaction cup incubation plate 30 and the process of transferring the incubated reaction cup from the reaction cup incubation plate 30 to the detection module 50 are both completed by the cup gripping module. Compared with the prior art, which uses two independent and far apart cup gripping devices to complete the above two transfer processes, the integration of the cup gripping module is improved and the space occupied by the cup gripping module is reduced. Simultaneously, the transverse track 71 of the third transfer needle module 63 extends from above the reagent cooling chamber 40 to above the base plate 51, causing the movement range of the third transfer needle module 63 to intersect with the movement range of the gripping cup module, thus completing the addition of reagents. The movement range of the third transfer needle module 63 is as follows: Fig. 2 As shown in frame A.

[0025] Furthermore, the cup-grabbing module includes a first cup-grabbing module 81 and a second cup-grabbing module 82. Both the first and second cup-grabbing modules 81 and 82 include a three-axis manipulator and a gripper 811 mounted on the manipulator. The three-axis manipulator includes a horizontal track 71, a vertical track 72, and a longitudinal track, respectively enabling the gripper 811 to move in the X, Y, and Z directions in three-dimensional space. The horizontal track 71 of the first cup-grabbing module 81 extends from above the reaction cup incubation tray 30 to above the first mixer 54, so that the movement range of the first cup-grabbing module 81 covers the reaction cup incubation tray 30, the magnetic bead detection module 52, the first mixer 54, and the empty cup input track 21, as shown below. Fig. 2 As shown in frame B, the system facilitates the transfer of an empty reaction vessel from the empty vessel input track 21 to the reaction vessel incubation tray 30, the transfer of the incubated reaction vessel from the reaction vessel incubation tray 30 to the first mixer 54, and the transfer from the first mixer 54 to the magnetic bead detection module 52. The transverse track 71 of the second cup-grabbing module 82 extends from above the first mixer 54 to above the optical detection module 53, ensuring that the movement range of the second cup-grabbing module 82 covers both the first mixer 54 and the optical detection module 53. Fig. 2The middle C frame realizes the transfer of the reaction cup from the first mixer 54 to the optical detection module 53. The cup grabbing module is divided into a first cup grabbing module 81 and a second cup grabbing module 82 according to the moving range to improve the detection efficiency. The magnetic bead detection module 52 and the optical detection module 53 are also provided with a cup discarding port, which is connected to a waste barrel through a pipeline, and the reaction cup after detection is grabbed by the first and second cup grabbing modules to the respective cup discarding ports for discarding.

The lateral track 71 of the third transfer needle module 63 is arranged on the same side as the lateral track 71 of the second cup grabbing module 82, opposite to the lateral track of the first cup grabbing module 81, and the needle tube 611 of the third transfer needle module 63 and the gripper 811 of the first cup grabbing module 81 face each other, so that the moving range of the third transfer needle module 63 intersects with the moving range of the first cup grabbing module 81 to complete the addition of certain reagents.

[0028] Further, the first, second and third transfer needle modules 61, 62, 63 are provided with a cleaner in the moving track coverage range of the needle tube 611 for cleaning the inner and outer walls of the needle tube 611.
