[0032] Implementation Method 1

[0033] Reference Figures 1 to 4 This embodiment is an optional embodiment of the present application, which discloses a blood transfusion device with a shaking function, including a chassis 1 and a mixing plate 2, wherein a hinge seat is provided in the chassis 1, and a hinge shaft is also provided at the middle position of the bottom of the mixing plate 2, wherein the hinge shaft is rotatably connected to the hinge seat, thereby realizing the rotatable connection between the mixing plate 2 and the chassis 1;

[0034] A driving module and a reset module are also provided in the chassis 1, and the driving module and the reset module are arranged on both sides of the hinge shaft;

[0035] The driving module comprises a driving motor 3 and a driving screw 4, wherein the output shaft of the driving motor 3 is connected to the driving screw 4 by a coupling; at the same time, slide rails 7 are arranged on both sides of the driving screw 4, and the two slide rails 7 are parallel to each other;

[0036] The driving screw 4 is threadedly connected with a driving block 5, and two sides of the bottom of the driving block 5 are provided with slide seats 8, and the two slide seats 8 are respectively slidably connected with the two slide rails 7;

[0037] The two slide rails 7 not only limit the rotation of the drive block 5, but also effectively reduce the movement friction and movement wear of the drive block 5, thereby extending the service life of the equipment;

[0038] A driving inclined surface 6 is provided on the top surface of the driving block 5, and a wedge-shaped block 9 is also provided on the bottom surface of the mixing plate 2, and the bottom surface of the wedge-shaped block 9 is completely in contact with the driving inclined surface 6;

[0039] In the above structure, the swing speed and the swing frequency of the mixing plate 2 can be adjusted by controlling the rotation speed of the adjusting screw; at the same time, the position of the driving block 5 can be adjusted by controlling the number of rotations of the driving screw 4, and the different positions of the driving block 5 will directly lead to the change of the inclination angle of the mixing plate 2, so that the inclination angle of the mixing plate 2 can be adjusted arbitrarily according to needs; and the diversified use needs can be met as much as possible;

[0040] At the same time, the device has a simple structure and high reliability and stability.

[0041] A travel switch 10 is provided at both ends of the two slide rails 7, and a controller is also provided on the chassis 1, the controller includes a PCB control board, a display screen and a plurality of control buttons, and it should be noted that a touch screen control can also be used; each of the travel switches 10 is electrically connected to the PCB control board; the drive motor 3 is also electrically connected to the PCB control board;

[0042] The reset module comprises a telescopic rod 11 and a reset sleeve 12, wherein the reset sleeve 12 is arranged in the chassis 1, one end of the telescopic rod 11 is inserted into the reset sleeve 12, and a reset spring 13 is also arranged in the reset sleeve 12, and the top end of the reset spring 13 abuts against the end surface of the end of the telescopic rod 11 inserted into the reset sleeve 12;

[0043] At the same time, a limiting groove 17 is also provided on the reset sleeve 12, and a limiting screw 18 is slidably provided in the limiting groove 17, and the limiting screw 18 is threadedly connected to the telescopic rod 11;

[0044] An adjusting slide rail 14 is also provided on the bottom surface of the mixing plate 2, and an adjusting slider 15 is slidably provided on the adjusting slide rail 14, and the bottom of the adjusting slider 15 is hingedly connected to the telescopic rod 11 through a pin shaft;

[0045] A recycling motor 19 and a recycling roller 20 are also provided on the top surface of the mixing plate 2, wherein the recycling motor 19 and the recycling roller 20 are provided on one side of the mixing plate 2, the recycling roller 20 is rotatably provided on the mixing plate 2 through a bearing seat, and the recycling motor 19 is connected to the recycling roller 20 through a coupling;

[0046] A hook 21 is also provided on the recycling roller 20, and a mounting frame 22 is also provided on the mixing plate 2. The mounting frame 22 is provided between the recycling roller 20 and the blood transfusion bag placement area, and an upper squeezing roller 23 and a lower squeezing roller 24 are rotatably provided on the mounting frame 22. The non-output end of the blood transfusion bag passes through the gap between the upper squeezing roller 23 and the lower squeezing roller 24 and is connected to the hook 21.

[0047] The recovery motor 19 is electrically connected to the controller;

[0048] During blood transfusion, the non-output end of the blood transfusion bag passes through the gap between the upper squeezing roller 23 and the lower squeezing roller 24 and is connected to the hook 21. After part of the blood is output, the recovery motor 19 drives the recovery roller 20 to rotate, and then winds around the empty bag body on the upper part of the recovery infusion bag. At the same time, the remaining blood is driven and concentrated at the output end of the infusion bag through the squeezing of the upper squeezing roller 23 and the lower squeezing roller 24, thereby increasing the pressure in the infusion bag.

[0049] When the blood transfusion device described in the present application is used, the driving motor controls the driving screw to rotate, and the driving screw controls the driving block to move toward one side of the mixing plate. Since the top surface of the driving block is inclined with a driving inclined surface, the driving inclined surface will push the mixing plate to rotate around the hinge axis. During the rotation process, the telescopic rod located on the other side of the hinge axis will move downward, thereby compressing the reset spring.

[0050] When the mixing plate moves to the extreme position, the driving motor is controlled to reverse, driving the driving block away from the mixing plate. At this time, due to the disappearance of the thrust of the driving block, the mixing plate will rotate in the opposite direction under the action of the resetting module;

[0051] Repeating the above process continuously can achieve uninterrupted shaking of the mixing plate, thereby avoiding red blood cell sedimentation and ensuring that the red blood cells are evenly distributed throughout the blood transfusion bag;

[0052] At the same time, during the shaking process, the recovery motor can also drive the recovery roller to rotate, thereby recovering the empty infusion bag to ensure the internal pressure of the infusion bag;

[0053] Compared with the prior art, the present application can arbitrarily adjust the position and movement speed of the driving block through the driving motor, wherein the adjustment of the driving block position can arbitrarily control the rotation angle of the mixing plate, and can also arbitrarily control the starting angle and the end angle. The adjustment has high flexibility and can meet different usage requirements, avoid the precipitation of red blood cells in the blood, ensure that the red blood cells can be evenly distributed in the blood transfusion bag, and thereby ensure that the red blood cells can be stably and continuously output during the blood transfusion process.

[0054] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
