[0003] In the prior art, the steps for testing and processing blood samples are generally as follows: blood sample collection → anticoagulant addition → oscillation mixing → centrifugation → sample distribution → specific processing → result analysis, wherein the purpose of oscillation mixing is to evenly mix the blood sample with the reagent, effectively avoiding the sedimentation of the blood sample, thereby improving the accuracy of the blood test; however, in the actual operation process, before oscillating and mixing multiple groups of blood samples, it is necessary to quantitatively and accurately add the anticoagulant into the blood sample tube through a disposable syringe, pipette or dropper, and then the single blood sample The test tubes are positioned and installed one by one in the oscillating mixing device, or multiple groups of blood sample test tubes are temporarily stored in a test tube rack and then centrally positioned and installed in the oscillating mixing device. The above-mentioned positioning and installation of multiple groups of blood sample test tubes with anticoagulants one by one or in a centralized manner both have certain inconveniences. In addition, after the blood samples are oscillated and mixed, it is also inconvenient to take out the multiple groups of blood sample test tubes.

[0044] Example 1

[0045] See also Figure 1-9 The present invention provides a blood oscillation and mixing device for blood testing, comprising a processing box 1, and a rotating column 2, the rotating column 2 is rotatably mounted at the center of the inner wall of the processing box 1, two rotating plates 3 distributed up and down are fastened and sleeved on the top outer surface of the rotating column 2, and a stepping motor 4 coaxially connected to the rotating column 2 is installed at the bottom of the processing box 1;

[0046] Sliding rods 5, multiple sliding rods 5 are provided and evenly distributed around the circumference, the sliding rods 5 slide through the surface of the bottom rotating plate 3, the bottom outer surface of each sliding rod 5 is tightly sleeved with an elastic clamping ring 6, and a propulsion mechanism 7 for synchronous movement of multiple sliding rods 5 is provided between the two rotating plates 3;

[0047] Both outer ends of the elastic clamping ring 6 are provided with arc-shaped strips facing outwards, and the distance from the bottom of the sliding rod 5 to the center of the rotating plate 3 is greater than the distance from the top of the sliding rod 5 to the center of the rotating plate 3;

[0048] A placement slide rail 8, wherein a plurality of placement slide rails 8 are provided and correspond one-to-one with the plurality of sliding rods 5, and the plurality of placement slide rails 8 are integrally formed on the top outer surface of the processing box 1, and a support plate 9 corresponding one-to-one with the placement slide rails 8 is provided inside the processing box 1, and a resistance closing mechanism 10 cooperating with the propulsion mechanism 7 is commonly provided on the periphery of the plurality of support plates 9;

[0049] It should be noted that, according to the figure, there are eight sliding rods 5, that is, the blood sample oscillation mixing device referred to in this case is used to handle a maximum of eight groups of blood sample tubes. Through the setting of the pushing mechanism 7, the eight sliding rods 5 can be pushed inward or outward synchronously on the rotating plate 3 below;

[0050] The processing box 1 is placed in the laboratory, and its operation must ensure sterility and safety. In addition, the top inner wall of the processing box 1 is provided with a rotating slideway adapted to the blood sample tube;

[0051] It should be noted that, through the setting of the pushing mechanism 7, when the eight sliding rods 5 are located at the outermost periphery of the rotating plate 3, the eight elastic clamping rings 6 are located above the placement slide rail 8. At this time, eight groups of blood sample tubes to be shaken and mixed can be placed in turn on the top surface of the slide rail and slid into the rotating slide groove. At this time, the elastic clamping rings 6 are squeezed and the inner surface of the elastic clamping rings 6 clamps the outer surface of the blood sample tube, forming a clamping and supporting treatment for the blood sample tube. At this time, the height of the top surface of the blood sample tube is equal to the height of the bottom surface of the rotating plate 3 below.

[0052] When anticoagulants are added to eight groups of blood samples, the stepper motor 4 drives the two rotating plates 3 to rotate forty-five degrees one by one, that is, the next blood sample tube rotates in the rotating slide of the processing box 1 to the first injection area, and a new disposable syringe is used to inject the anticoagulant each time, without the need to transfer multiple disposable syringes to the top of the blood sample tube for injection and addition processing, which improves the convenience of injecting anticoagulants into the eight blood sample tubes to a certain extent;

[0053] The setting of the contact closing mechanism 10, through the pushing mechanism 7, multiple blood sample test tubes are synchronously pushed from the placement slide rail 8 to the inside of the processing box 1. At this time, the outer surface of the contact ring block 106 in the contact closing mechanism 10 first contacts the top surface of the blood sample test tube, and drives the blood sample test tube to move downward in the elastic clamping ring 6 and contact the supporting plate 9, so that the bottom of the blood sample test tube forms a conflict with the top surface of the supporting plate 9. When the blood sample test tube moves to the inside of the processing box 1 with the pushing mechanism 7, the blood sample test tube moves toward the center of the supporting plate 9 and drives the supporting plate 9 to press downward for processing. Finally, the contact closing mechanism 10 forms a closing and clamping processing on the outer surface of the blood sample test tube, and cooperates with the elastic clamping effect of the elastic clamping ring 6 on the blood sample test tube, so as to further improve the stability of the simultaneous transfer of multiple blood sample test tubes to their respective supporting plates 9 for contact clamping installation, and the operation has a high degree of automation, saving time and effort.

[0054] Further as Figure 4 , Figure 5 and Figure 6 As shown, it is worth to explain in detail that the propulsion mechanism 7 includes a turntable 71, a plurality of turntables 71 are provided and correspond to the plurality of sliding rods 5 one by one, the turntable 71 is rotatably mounted on the inner wall of the rotating plate 3 at the top, and an adjusting member 72 for synchronous movement of the plurality of turntables 71 is provided on the periphery of the rotating plate 3 at the top, a column 73 is embedded in the inner wall of the bottom of the turntable 71, and a T-shaped limiting ring 74 is sleeved on the outer surface of the column 73, and the top end of the sliding rod 5 is embedded and fixed to the inner wall of the adjacent T-shaped limiting ring 74;

[0055] U-shaped blocks 75, which are provided in plurality and correspond to the plurality of T-shaped limiting rings 74 one by one, the U-shaped blocks 75 are fixed to the top surface of the rotating plate 3 at the bottom, and the ends of the T-shaped limiting rings 74 are slidably inserted into the interior of the adjacent T-shaped limiting rings 74;

[0056] It should be noted that when multiple blood sample tubes are pushed forward synchronously, the multiple sample tubes are slid in turn from the top surface of the slide rail 8 to form an elastic clamping treatment with the elastic clamping ring 6, and then anticoagulants are injected into the interior of each tube by driving the stepper motor 4. The multiple turntables 71 are driven by the adjusting member 72 to rotate synchronously, that is, the turntable 71 drives the column 73 to rotate from the periphery of the rotating plate 3 toward the inside, and the U-shaped block 75 limits the T-shaped limit ring 74 and the T-shaped limit ring 74 is always sleeved on the outer surface of the column 73, so that the multiple T-shaped limit rings 74 drive the sliding rod 5 to move toward the center of the rotating plate 3, that is, the multiple blood sample tubes are moved to the top of the processing box 1 with the sliding rod 5 and the elastic clamping ring 6, completing the synchronous and automatic advancement and delivery of the multiple blood sample tubes.

[0057] Further as Figure 1 , Figure 2 and Figure 5 As shown, it is worth to explain in detail that the adjusting member 72 includes a rotating gear 721, and the rotating gear 721 is provided with a plurality of rotating gears 721 and is respectively fixedly arranged coaxially with the plurality of rotating disks 71 in a one-to-one manner, and a central toothed ring 722 is meshed between the plurality of rotating gears 721, and a fixing ring 723 is fixed to the bottom surface of the rotating plate 3 located above, and the inner wall of the central toothed ring 722 is fitted to the outer surface of the fixing ring 723;

[0058] The rotating wheel 724 is arranged on the top surface of the rotating plate 3 located above and is coaxially fixed with one of the rotating gears 721. The top surface of the rotating plate 3 located above is provided with a sleeve 725 on the outer surface of the rotating shaft of the rotating wheel 724. The outer surface of the sleeve 725 is threadedly connected with a limiting bolt 726;

[0059] It should be noted that, by releasing the locking effect of the limit bolt 726 on the shaft sleeve 725, the rotating wheel 724 drives one of the rotating disks 71 and the rotating gear 721 to rotate 180 degrees, and the meshing transmission of multiple rotating gears 721 and the central toothed ring 722 causes the other rotating disks 71 to rotate 180 degrees, so that the multiple sliding rods 5 and the elastic clamping ring 6 drive their respective blood test samples to be synchronously pushed into the interior of the processing box 1;

[0060] When multiple blood sample tubes move synchronously into the processing box 1, the limiting bolt 726 is threadedly rotated in the sleeve 725, so that the end of the limiting bolt 726 limits the rotating shaft of the rotating wheel 724, so that the sliding rod 5 and the elastic clamping ring 6 are stably located below the two rotating plates 3.

[0061] Further as Figure 2 , Figure 8 and Fig. 9As shown, it is worth specifically explaining that the abutting closing mechanism 10 includes a supporting sleeve 101, and the supporting sleeve 101 is provided with a plurality of supporting sleeves 101, and the plurality of supporting sleeves 101 are fixed one by one to the bottom surfaces of the plurality of supporting plates 9, and a rotating sleeve 102 is slidably sleeved on the outer surface of the bottom of each supporting sleeve 101, and the outer surfaces of the plurality of rotating sleeves 102 are jointly provided with a track ring 103 fixed to the inner wall of the bottom of the processing box 1, and the inner wall of the bottom of the processing box 1 is provided with a limiting plate 104 embedded in the rotating sleeve 102, and a tightening spring 105 is fixed to the opposite surface of the limiting plate 104 and the adjacent supporting sleeves 101;

[0062] A resisting ring block 106, which is sleeved on the outer surface of the plurality of sliding rods 5, and is fixed to the bottom surface of the rotating plate 3 located below. A closing member 107 matching with the supporting sleeve 101 is provided below the resisting ring block 106;

[0063] It should be noted that when the blood sample test tubes are not sent into the processing box 1, the supporting plate 9 is at the same height as the inner wall of the rotating groove of the placement slide rail 8 of the processing box 1 due to the elastic force of the pressing spring 105, so that multiple blood sample test tubes can be moved to the top surface of the supporting plate 9 at the rotating groove of the placement slide rail 8, until the top surface of the blood sample test tube moves to the abutment ring block 106 to move downward and abut against the top surface of the supporting plate 9;

[0064] It should be noted that when the blood sample tube contacts the top surface of the support plate 9, the contact ring block 106 squeezes the top surface of the blood sample tube at an angle. At this time, the blood sample tube moves toward the center at the edge of the top surface of the support plate 9, and at the same time drives the support plate 9 to move downward in the rotating sleeve 102 through the support sleeve 101, and compresses the clamping spring 105. At this time, the support sleeve 101 moves downward in the rotating sleeve 102, driving the closing member 107 to rotate toward the center of the support plate 9 synchronously, that is, driving the closing member 107 to close the surface of the blood sample tube moving on the top surface of the support plate 9.

[0065] Further as Figure 1 , Figure 6 and Figure 8 As shown, it is worth to explain in detail that the closing member 107 includes a fixing seat 1071, and the fixing seat 1071 is provided with three and the three fixing seats 1071 are fixedly distributed at equal angles on the top outer surface of the rotating sleeve 102, and the inner wall of each fixing seat 1071 is rotatably connected with a closing gear 1072, and the outer surface of the supporting sleeve 101 is provided with a toothed groove meshing with the closing gear 1072;

[0066] The arc rods 1073 are provided in plurality and are coaxially fixed one by one to the outer surfaces of the plurality of fixing seats 1071 , and the top end of each arc rod 1073 is rotatably connected to a closing rod 1074 ;

[0067] The abutment ring block 106 includes a circular ring segment and an abutment segment. The outer surface of the abutment ring block 106 away from the center of the rotating plate 3 is arranged in an inclined slope. The central segments of the three closing rods 1074 are distributed in parallel. The bottom end of the closing rod 1074 is located at the periphery of the arc rod 1073.

[0068] It should be noted that the center of gravity of the closing rod 1074 is offset toward the outer surface of the arc-shaped rod 1073, so that the diameter of the circular ring formed by the three closing rods 1074 gradually decreases from top to bottom. When the blood sample test tube moves into the three arc-shaped rings and contacts the closing rods 1074, the outer surface of the bottom of the blood sample test tube gradually squeezes the bottom end of the closing rod 1074, so that the blood sample test tube moves to the center on the supporting plate 9;

[0069] When the blood sample test tube moves to the center of the support plate 9, the three arc-shaped rods 1073 rotate synchronously toward the center through the meshing transmission of the closing gear 1072 and the toothed groove on the outer surface of the support sleeve 101, that is, the blood sample test tube is moved and clamped in the interval formed by the three arc-shaped rods 1073 until the blood sample test tube is located at the center of the support plate 9 and the three closing rods 1074 close and contact the outer surface of the blood sample test tube. In addition, it should be noted that the closing rod 1074 can be made of silicone rubber or fluororubber with certain elastic characteristics, so as to avoid movement interference between the blood sample test tube and the three closing rods 1074;

[0070] It should be noted that when the blood sample tube moves toward the inside of the processing box 1 with the propulsion mechanism 7, the blood sample tube is moved on the surface of the support plate 9 toward the center of the support plate 9 through the resistance of the resistance ring block 106. At the same time, the support plate 9 is pressed downward on the inner wall of the rotating sleeve 102 by the support sleeve 101. Through the meshing transmission action of the toothed groove in the support sleeve 101 and the closing gear 1072, the support plate 9 drives the arc rod 1073 to rotate toward the center during the downward resistance and pressing process, that is, drives the closing rod 1074 on the arc rod 1073 to synchronously close the outer surface of the blood sample tube, forming three closing rods 1074 to close, clamp and limit the blood sample tube.

[0071] This embodiment has the following working process: when a plurality of groups of blood sample test tubes are mixed and treated uniformly, each sample test tube is first pushed from the placement slide rail 8 to form an elastic docking treatment with the elastic clamping ring 6, and then driven by the stepping motor 4, the two rotating plates 3 drive the plurality of groups of blood sample test tubes to rotate at the rotating slide groove of the placement slide rail 8, and each time a new disposable syringe is used to gradually inject anticoagulant into each blood sample test tube, and then the plurality of groups of blood sample test tubes injected with anticoagulant are driven by the propulsion mechanism 7 to synchronously move into the processing box 1, and the sliding rod 5 and the elastic clamping ring 6 are limited by the limiting bolts of the adjusting member 72;

[0072] When the blood sample test tube is sent into the processing box 1 through the pushing mechanism 7, the blood sample test tube is subjected to a conflicting treatment with the supporting plate 9 through the conflicting closing mechanism 10. During the continuous pushing of the blood sample test tube, the supporting plate 9 is pressed downward, and at the same time, the three closing rods 1074 in the closing member 107 form a critical state for closing the outer surface of the blood sample test tube, thereby achieving synchronous closing of multiple blood sample test tubes, completing the automatic position-limiting installation of multiple groups of blood sample test tubes, and ensuring the installation stability of multiple blood sample test tubes on the rotating plate 3 and the supporting plate 9;

[0073] The stepper motor 4 drives the rotating column 2 and the rotating plate 3 to move synchronously, and the pushing mechanism 7 and the contact closing mechanism 10 cooperate to make the contact ring block 106, the blood sample test tube and the supporting plate 9 form a tight contact state and rotate on the inner wall of the processing box 1, so that multiple groups of blood sample test tubes are mixed and processed uniformly;

[0074] After multiple groups of blood sample tubes are rotated and shaken to be evenly mixed, the adjusting member 72 is adjusted so that the sliding rod 5 and the elastic clamping ring 6 drive the blood sample tubes to be pushed outward synchronously for processing. At this time, the three closing rods 1074 in the closing mechanism 10 first release the closing effect on the blood sample tubes, and then the top surface of the supporting plate 9 is reset to the rotating slide groove of the slide rail 8, and then the evenly mixed blood sample tubes are taken out one by one from the elastic clamping rod, and then the blood sample tubes are sent to the centrifuge for centrifugal separation, and then the samples are distributed, specifically processed and the results are analyzed to complete the detection and processing of the blood samples.

[0075] Example 2

[0076] Based on the first embodiment, Figure 1 , Figure 3 , Figure 6 , Figure 7 and Fig. 9As shown, it is worth to explain in detail that a planetary transmission mechanism 11 is arranged between the plurality of rotating sleeves 102, and the planetary transmission mechanism 11 includes a planetary gear 111, and the planetary gear 111 is provided with a plurality of and one by one is coaxially fixed to the outer surface of the plurality of rotating sleeves 102, and a sun gear 112 is fastened and sleeved on the outer surface of the rotating column 2, and the sun gear 112 and the plurality of planetary gears 111 are arranged in meshing connection;

[0077] A fixed gear ring 113, the fixed gear ring 113 is fixed to the inner wall of the processing box 1, and a plurality of planetary gears 111 are meshed and installed inside the fixed gear ring 113;

[0078] It should be noted that the sun gear 112 rotates synchronously with the rotating column 2, and the fixed ring gear 113 is fixed to the inner wall of the processing box 1. Through the meshing transmission among the sun gear 112, the planetary gears 111 and the fixed ring gear 113, the planetary gear 111 drives the rotating sleeve 102 to rotate, and the planetary gear 111 also revolves with the rotating plate 3, so that the supporting plate 9 and the blood sample tube form a rolling process on the fixed ring gear 113 in the processing box 1, making the movement trajectory of the blood sample tube more diverse, making the blood sample oscillation and mixing more uniform, providing sufficient guarantee for the accuracy of subsequent blood test results.

[0079] In summary, in combination with the two embodiments, it can be known that: by placing the slide rail 8 and the elastic clamping ring 6 to form a clamping support for the blood sample tube, and by driving the stepping motor 4, multiple blood sample tubes are rotated at equal angles, so that it is convenient to inject anticoagulants into different blood sample tubes at the same position with a disposable syringe, which improves the convenience of injecting anticoagulants into different blood sample tubes to a certain extent;

[0080] Through the setting of the pushing mechanism 7, multiple blood sample tubes that have been injected with anticoagulants are synchronously moved to the inside of the processing box 1, and through the cooperation of the resistance closing mechanism 10 and the pushing mechanism 7, multiple blood sample tubes are subjected to resistance processing with the supporting plate 9. At the same time, each blood sample tube is closed by three closing rods 1074, which has a high degree of automation, saves time and labor, and cooperates with the elastic clamping ring 6 to elastically clamp the blood sample tube, further improving the stability of the installation and processing of multiple blood sample tubes.

[0081] The synchronous propulsion and the resisting and closing clamping installation of the multiple blood sample tubes by the propulsion mechanism 7 and the resisting and closing mechanism 10 effectively ensure the installation convenience and stability of the multiple blood sample tubes. The support plate 9 and the blood sample tubes are rolled on the fixed gear ring 113 in the processing box 1 by the setting of the planetary transmission mechanism 11 and the driving of the stepping motor 4, so that the movement trajectory of the blood sample tubes is more diverse, and the blood samples are oscillated and mixed more evenly, providing sufficient guarantee for the accuracy of the subsequent blood test results.

[0082] The stepper motor 4 can be purchased from the market and equipped with a separate power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.

Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
