Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a mixing device of a mixing and sorting machine. Background Art

[0002] The workflow in modern medical testing laboratories primarily involves labeling, blood collection, transportation, mixing, and testing. Before blood samples are analyzed, they must be sorted based on label information so they can be sent to the appropriate testing center for centralized processing. Currently, specimen sorting is mostly done manually, which is labor-intensive and inefficient. Some hospitals use automated blood collection tube sorting equipment to perform this sorting.

[0003] The blood collection tube sorting equipment in the existing technology has functions such as specimen information reading and sorting, and directional specimen transportation. After the doctor at the blood collection window puts the collected specimen into the hopper, the specimen is automatically sorted and transported to the collection module without manual intervention, reducing the workload of medical staff and shortening the time to provide test reports, thereby improving work efficiency and service quality.

[0004] However, the above-mentioned blood collection tube sorting equipment does not have a shaking function, and is unable to shake the blood collection tubes during the sorting operation. The blood collection tubes with anticoagulants should be repeatedly inverted and mixed 5 to 8 times after the blood enters, so that the blood and the anticoagulant are fully mixed to ensure that the blood will not coagulate after sampling. This step mainly relies on manual operation by nurses in actual work. When collecting multiple tubes of blood samples at the same time, it is difficult for a single person to operate according to the standard requirements, which will lead to errors in the inspection. In addition, repeated manual shaking of the blood collection tubes increases the labor intensity of medical staff, making medical staff prone to wrist muscle strain. Therefore, it is urgent to design a mixing device suitable for the blood collection tube mixing and sorting machine to solve the above problems. Utility Model Content

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail:

[0020] See Figure 1The mixing device of the present invention includes a laterally adjustable mixing and sorting frame 4, movably connected to a longitudinally movable mounting base 5. A tube grabbing assembly 7 is mounted on the longitudinally movable mounting base 5 for grabbing test tubes. This embodiment also includes a shaking drive assembly 8 mounted on the longitudinally movable mounting base 5 for rotating the tube grabbing assembly 7, and a lifting drive assembly 6 for lifting and lowering the longitudinally movable mounting base 5.

[0021] like Figure 2 As shown, the tube-grabbing assembly 7 comprises an electric gripper 7-1 movably connected to a longitudinally movable mounting base 5. Two opposing sets of tube-gripping jaws 7-2 are mounted on the movable ends of the electric gripper 7-1. Both sets of tube-gripping jaws 7-2 have arcuate grooves formed on their opposing surfaces to accommodate the caps of test tubes. The tube-grabbing assembly 7 also comprises a mounting plate 7-4 mounted on the electric gripper 7-1. Mounted on the mounting plate 7-4 is a detection sensor 7-3 located above the two sets of tube-gripping jaws 7-2 for sensing the presence of a test tube to be grasped.

[0022] like Figure 2 As shown, the above-mentioned lifting drive assembly 6 includes a guide rail pair installed on the mixed picking mounting frame 4 for slidingly mounting the longitudinal moving mounting seat 5 and arranged longitudinally, and also includes a lifting transmission pair 6-2 installed on the mixed picking mounting frame 4 and arranged parallel to the guide rail pair. The longitudinal moving mounting seat 5 is connected to the lifting transmission pair 6-2, and also includes a lifting motor 6-1 for driving the lifting transmission pair 6-2 to operate.

[0023] The lifting drive assembly 6 also includes two sets of pulley seats 6-4 installed on the mixed picking mounting frame 4 in an upper and lower distribution. The lifting transmission pair 6-2 includes a driving pulley and a driven pulley rotatably connected on the above-mentioned two sets of pulley seats 6-4. A closed belt is connected for transmission between the driving pulley and the driven pulley. A mounting seat pressure plate 6-3 is installed on the above-mentioned longitudinal movement mounting seat 5. The longitudinal movement mounting seat 5 is connected to the belt in the lifting transmission pair 6-2 through the mounting seat pressure plate 6-3.

[0024] The lifting drive assembly 6 also includes two groups of second in-place sensors 6-5 installed on the mixed picking mounting frame 4 in an upper and lower distribution. A sensing plate that cooperates with the second in-place sensor 6-5 is installed at the lower part of the longitudinal moving mounting seat 5. The sensing plate and the two groups of second in-place sensors 6-5 are used to control the up and down strokes of the longitudinal moving mounting seat 5.

[0025] When the feeding device 9 is lifted up, the lifting motor 6-1 is started, and the lifting motor 6-2 is stopped, so that the cap of the test tube on the feeding device 9 is grasped and the cap of the test tube on the feeding device 9 is grasped.

[0026] After completing the above-mentioned pipe clamping and material picking operation, the PLC controller controls the lifting motor 6-1 to start again, driving the pipe grabbing assembly 7 to move upward until the induction plate installed on the longitudinal movement mounting seat 5 triggers the second in-position sensor 6-5 located above. After receiving the information transmitted by the above-mentioned second in-position sensor 6-5, the PLC controller controls the lifting motor 6-1 to stop running and wait for the shaking drive assembly 8 to drive the pipe grabbing assembly 7 to rotate to perform the shaking and mixing operation;

[0027] like Figure 2 As shown, the aforementioned rocking drive assembly 8 includes a rotary transmission shaft 8-3 mounted at the end of the electric gripper 7-1, and a rotary drive mechanism for driving the rotary transmission shaft 8-3 to rotate. The rotary drive mechanism includes a transversely disposed rocking motor 8-1 mounted on the longitudinal displacement mounting base 5, and a rocking transmission pair 8-2 is mounted between the output shaft of the rocking motor 8-1 and the rotary transmission shaft 8-3. The rocking transmission pair 8-2 includes a driving pulley keyed to the output shaft of the rocking motor 8-1, and a driven pulley keyed to the rotary transmission shaft 8-3, with a belt in a closed state being connected between the driving pulley and the driven pulley. Furthermore, to control the number of revolutions of the pipe grasping assembly 7, a rotary code disk 8-4 is mounted on the rotary transmission shaft 8-3, which rotates synchronously therewith, and a pipe shaking sensor 8-5 for sensing the rotary code disk 8-4. The pipe shaking sensor 8-5 is mounted on the longitudinal displacement mounting base 5. In addition, a longitudinally extending avoidance operation groove 4-1 is provided on the mixed picking mounting frame 4, and the rocking tube transmission pair 8-2 is inserted into the avoidance operation groove 4-1 and is clearance-matched therewith.

[0028] See further Figure 1This embodiment also includes a mounting base 2 with multiple sets of universal casters 1 installed at the bottom, and a transverse driving assembly 3 is installed on the mounting base 2, which is used to drive the pipe grabbing assembly 7 to move back and forth laterally between the pipe taking station and the sorting and collecting station of the mixed sorting machine.

[0029] See further Figure 3 and Figure 4 The transverse drive assembly 3 includes a transverse guide rail 3-7 fixedly attached to the mounting base 2 and extending along its length, a transverse mounting base 3-4 slidably connected to the transverse guide rail 3-7 via a slider, a mixed sorting mounting frame 4 mounted on the transverse mounting base 3-4, and a transverse driving pulley 3-5 and a transverse driven pulley 3-6 rotatably connected to the mounting base 2. The transverse driving pulley 3-5 and the transverse driven pulley 3-6 are respectively adjacent to the ends of the transverse guide rail 3-7. A transverse drive belt 3-3 is connected between the transverse driving pulley 3-5 and the transverse driven pulley 3-6, and the transverse mounting base 3-4 is connected to the transverse drive belt 3-3 via a pressure plate. The transverse drive assembly 3 also includes a transverse motor 3-1 for driving the transverse driving pulley 3-5 to rotate.

[0030] like Figure 3 As shown, the transverse drive assembly 3 also includes a first in-position sensor 3-2 mounted on the mounting base 2, adjacent to the pipe unloading station, and a sensing plate mounted on the transverse mounting base 3-4, cooperating with the first in-position sensor 3-2. During operation, when the pipe grabbing assembly 7 moves to the pipe unloading station under the drive of the transverse drive assembly 3, the sensing plate triggers the first in-position sensor 3-2, thereby stopping the transverse motor 3-1 in the transverse drive assembly 3.

[0031] Working principle:

[0032] In the actual working process, when the tube grabbing assembly 7 moves to the induction plate under the drive of the transverse driving assembly 3 to trigger the first in-position sensor 3-2, the detection sensor 7-3 detects the discharge end of the feeding device 9 and transmits the detection information to the PLC controller. If there is a test tube to be grabbed, the PLC controller controls the lifting motor 6-1 to start, drives the tube grabbing assembly 7 to move downward to the induction plate to trigger the second in-position sensor 6-5 located below, and then the PLC controller controls the lifting motor 6-1 to stop running, and controls the electric clamp 7-1 to start at the same time, grabs the tube cap of the test tube on the feeding device 9, and realizes the tube clamping and material taking operation;

[0033] After completing the above-mentioned tube clamping and material taking operation, the PLC controller controls the lifting motor 6-1 to start again, driving the tube grabbing assembly 7 to move upward until the induction plate triggers the second in-position sensor 6-5 located above, and then controls the tube shaking motor 8-1 to start, driving the tube grabbing assembly 7 to rotate, thereby driving the clamped test tube to be repeatedly inverted and mixed. During the mixing process, the mixing speed of the test tube can be controlled by controlling the rotation speed of the rotating transmission shaft 8-3, and the number of inversion and mixing times of the test tube can be controlled by the combined action of the rotating code disk 8-4 and the tube shaking sensor 8-5, thereby realizing the standardized operation of test tube mixing, so that the blood and anticoagulant are fully mixed, and there is no need for medical staff to manually mix the blood collection test tube, thereby reducing the workload and labor intensity of medical staff;

[0034] After completing the above-mentioned blood collection test tube mixing operation, the PLC controller controls the transverse movement motor 3-1 to start, driving the mixing and picking mounting frame 4 to move horizontally, and controls the moving distance of the mixing and picking mounting frame 4 according to the type of test tube detected by the identification sensor in the mixing and sorting machine, so that the test tube clamped by the tube grabbing assembly 7 is transferred to the collection position of the corresponding type, and then controls the electric clamp 7-1 in the tube grabbing assembly 7 to start, release the test tube clamped by the tube grabbing assembly 7, and make the test tube slide into the corresponding collection device; finally, start the transverse movement motor 3-1 again, drive the mixing and picking mounting frame 4 to move in the opposite direction, and then drive the tube grabbing assembly 7 to move to the tube retrieval station, and then repeat the above-mentioned tube retrieval, mixing and transfer and release operations.
