[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1-12 As shown, the present invention provides a technical solution: an intelligent blood cell separation device, including a housing 1 and a cover 2 rotatably connected to the top of the housing 1. The inner cavity of the housing 1 is respectively provided with a separation bottle 12 for holding blood, a feeding mechanism 7 for adding anticoagulant to the separation bottle 12, a stirring component 9 for stirring after adding anticoagulant to the separation bottle 12, a centrifugal component 10 for driving the separation bottle 12 to perform centrifugal motion after stirring, and a drive component 8 for providing power to the stirring component 9 and the centrifugal component 10.

[0040] The inner wall of the inner cavity of the housing 1 is provided with a lower circular groove 3 and an upper circular groove 4 respectively, and the inner wall of the housing 1 is rotatably connected to a lower circular plate 6 and an upper circular plate 5 through the lower circular groove 3 and the upper circular groove 4 respectively. A placement rack 13 is fixedly connected between the top of the upper circular plate 5 and the bottom of the lower circular plate 6. A through hole is provided at the top of the upper circular plate 5, and the separation bottle 12 can be placed in the placement rack 13 after being inserted into the through hole.

[0041] The feeding mechanism 7 includes a feeding box 71 fixedly connected to the top of the lower circular plate 6 via a support plate, a pneumatic check valve 72 connected to the top of the feeding box 71, an air pipe 73 connected to the input end of the pneumatic check valve 72, and a piston pipe 74 connected to the other end of the air pipe 73. A pneumatic check valve 75 is connected to the bottom of the piston pipe 74, and a piston block 76 is slidably connected to the inner wall of the piston pipe 74. A piston rod 77 is fixedly connected to the top of the piston block 76. The other end of the piston rod 77 passes through the top of the inner cavity of the piston pipe 74, the bottom of the upper circular plate 5, and extends to the top of the upper circular plate 5. A ring rod 78 is fixedly connected to the top of each piston rod 77. A hose 79 is connected to the bottom of the feeding box 71, and a flow check valve 710 is connected to the other end of the hose 79. A rigid tube 711 is connected to the output end of valve 710, and an auxiliary component 11 is provided on the outside of the rigid tube 711 for extending the other end of the rigid tube 711 into the separation bottle 12. A separation valve 1201 is connected to the bottom of the separation bottle 12, and a feeding port 1202 is provided on the outer wall of the separation bottle 12 near the top. The feeding port 1202 facilitates the addition of anticoagulant by extending the other end of the rigid tube 711 into the separation bottle 12 under the action of the auxiliary component 11. During the addition process, the anticoagulant will not be added outside the separation bottle 12, which is convenient for use. In addition, after the blood in the separation bottle 12 is centrifuged and separated, the separation bottle 12 is taken out from the housing 1. Then, the opening and closing of the separation valve 1201 is controlled to allow the plasma and blood cells in the separation bottle 12 to flow out respectively, thereby achieving the effect of blood cell separation.

[0042] During the closing process of the cover 2, a force is exerted on the ring rod 78, causing the ring rod 78 to move downward, thereby driving the piston rod 77 to move downward. The piston rod 77 will drive the piston block 76 to move downward along the piston tube 74, compressing the space below the piston tube 74. Through the transmission of the air pipe 73 and the pneumatic one-way valve 72, the power is transmitted to the feeding box 71. The anticoagulant in the pressurized feeding box 71 is delivered to the separation bottle 12 through the hose 79, the flow one-way valve 710, and the rigid pipe 711, thereby completing the addition of the anticoagulant.

[0043] The drive assembly 8 includes a motor 81, which is a geared motor and is fixedly installed at the bottom of the inner cavity of the housing 1 via a motor frame. The output end of the motor 81 is fixedly connected to a rotating shaft 82 via a coupling. The outer wall of the rotating shaft 82 is rotatably connected to the lower circular plate 6 via a bearing.

[0044] The drive assembly 8 provides the power source for the entire device. The motor 81 is a geared motor that can rotate in both forward and reverse directions. By controlling the forward and reverse rotation of the motor 81 and with the assistance of the stirring assembly and centrifugation assembly, the stirring and separation of blood can be completed.

[0045] The stirring assembly 9 includes a lower circular plate 6 rotatably connected to a rotating rod 93 via a bearing and a magnetic rotor 95 disposed inside the separation bottle 12. A driven gear 92 is fixedly sleeved on the outer wall of the other end of the rotating rod 93. A circular magnet 94 is fixedly connected to the top of the driven gear 92. The driven gear 92 is meshed with a driving gear 91. The driving gear 91 is fixedly sleeved on the outer wall of the rotating shaft 82.

[0046] The rotation of the shaft 82 drives the drive gear 91 to rotate, which in turn drives the driven gear 92 to rotate, thereby driving the circular magnet 94 to rotate. The rotation of the circular magnet 94 causes a change in the surrounding magnetic field, which in turn causes the magnetic rotor 95 inside the separation bottle 12 to rotate. The rotation of the magnetic rotor 95 in the blood generates eddy currents, which drive the blood to rotate, thereby achieving thorough mixing of the blood and anticoagulant without damaging the components in the blood.

[0047] The centrifugal assembly 10 includes a pawl 1003 and a limiting block 1001 fixedly connected to the outer wall of the rotating shaft 82 to limit the counterclockwise rotation of the pawl 1003, and a spring 1004 for assisting the pawl 1003 to deflect at a certain angle. A ratchet 1005 is fixedly connected to the bottom of the lower circular plate 6. A round rod 1002 is fixedly connected to the limiting block 1001. The pawl 1003 is rotatably sleeved on the outer wall of the round rod 1002, and the other end of the spring 1004 is fixedly connected to the outer wall of the pawl 1003.

[0048] The centrifuge assembly 10 is used to separate blood cells from the blood in the separation bottles in the casing. The combination of the limiting block 1001, the round rod 1002, the pawl 1003, the spring 1004, and the ratchet 1005 allows the rotating shaft 82 to rotate when it rotates forward, thereby rotating the lower circular plate 6. This centrifuges the blood in the multiple separation bottles 12 in the casing 1, causing the blood to separate into layers. Conversely, when the rotating shaft 82 rotates in reverse, the lower circular plate 6 does not rotate.

[0049] The auxiliary component 11 includes a square block 1103 fixedly sleeved on the outer wall of the rigid tube 711, and a strip block 1101 and a fixing rod 1106 respectively fixedly connected to the placement frame 13. A rotating component 1105 is rotatably connected to the outer wall of the fixing rod 1106. A spring 1102 is fixedly connected between the square block 1103 and the strip block 1101. A swing rod 1104 is fixedly connected to both sides of the square block 1103. The other end of the swing rod 1104 passes through the strip hole on the rotating component 1105.

[0050] During the process of placing the separating bottle 12 into the inner cavity of the housing 1, the downward movement of the separating bottle 12 will drive the rotating part 1105 to rotate around the fixed rod 1106. Through the lever principle, the other end of the rotating part 1105 will drive the block 1103 to move towards the strip block 1101 with the cooperation of the swing rod 1104, so that the block 1103 can extend the other end of the hard tube 711 into the separating bottle 12. Conversely, when the separating bottle 12 is taken out of the housing 1, the effect of the separating bottle 12 on the rotating part 1105 gradually decreases. Under the action of the second spring 1102, the block 1103 drives the other end of the hard tube 711 to move out of the separating bottle 12, so that the insertion and removal of the hard tube 711 can be automatically completed when the separating bottle 12 is picked up and put out.

[0051] Working principle: During use, as the operator places the separation bottle 12 into the inner cavity of the machine housing 1, the downward movement of the separation bottle 12 will cause the rotating component 1105 to rotate around the fixed rod 1106. Through the lever principle, the other end of the rotating component 1105, with the cooperation of the swing rod 1104, will drive the block 1103 to move towards the strip block 1101, thereby allowing the block 1103 to extend the other end of the rigid tube 711 into the separation bottle 12. During the closing process of the machine cover 2, a force will be exerted on the ring rod 78. This causes the ring rod 78 to move downwards, thereby moving the piston rod 77 downwards. The piston rod 77 then moves the piston block 76 downwards along the piston tube 74, compressing the space below the piston tube 74. Power is transmitted through the air pipe 73 and the pneumatic check valve 72 to the feeding tank 71. The anticoagulant in the pressurized feeding tank 71 is then delivered to the separation bottle 12 via the hose 79, the flow check valve 710, and the rigid pipe 711, thus completing the anticoagulant injection. Then, the pneumatic motor 81 controls the motor 8... 1. In forward rotation, motor 81 drives the rotating shaft 82, which in turn drives the drive gear 91, which in turn drives the driven gear 92, thus rotating the circular magnet 94. The rotation of the circular magnet 94 causes a change in the surrounding magnetic field, causing the magnetic rotor 95 inside the separation bottle 12 to rotate. The rotation of the magnetic rotor 95 in the blood generates eddy currents, causing the blood to rotate, thus achieving thorough mixing of the blood and anticoagulant without damaging the blood components. 2. Reverse rotation, controlling motor 81 to drive the rotating shaft 82 in reverse, which in turn drives the drive gear 91, which in turn drives the driven gear 92, thus rotating the circular magnet 94. The rotation of the circular magnet 94 causes a change in the surrounding magnetic field, causing the magnetic rotor 95 inside the separation bottle 12 to rotate. The rotation of the magnetic rotor 95 in the blood generates eddy currents, causing the blood to rotate, thus achieving thorough mixing of the blood and anticoagulant without damaging the blood components.

[0052] With the cooperation of the limiting fixing block 1001, the round rod 1002, the pawl 1003, the spring 1004, and the ratchet 1005, when the rotating shaft 82 rotates forward, it can drive the ratchet 1005 to rotate, thereby driving the lower round plate 6 to rotate. This allows the blood in the multiple separation bottles 12 inside the machine housing 1 to be centrifuged and separated, causing the blood to separate into layers. Then, the machine cover 2 is opened, the separation bottle 12 is taken out, and the opening and closing of the separation valve 1201 is controlled to allow the plasma and blood cells in the separation bottle 12 to flow out respectively, thereby achieving the effect of blood cell separation.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
