Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a whole blood mixing device. Background Art
[0002] Before testing blood samples, they need to be homogenized. In existing in vitro diagnostic testing instruments, whole blood samples are usually homogenized manually by shaking a single tube. Manual homogenization is not only inefficient, but also results in poor homogenization due to various issues. Existing technologies also use multi-row whole blood tubes for homogenization, but this requires placing multiple rows of blood collection tubes before homogenization can be achieved. If a single blood collection tube is homogenized using large equipment, it will result in significant waste. Alternatively, a large clamping and shaking device can be used for homogenization, but this large equipment takes up a lot of laboratory space and is not suitable for homogenizing blood samples for small testing instruments. Utility Model Content
[0003] This invention provides a whole blood mixing device that can improve the mixing effect of blood samples and enhance the convenience of whole blood mixing.
[0004] To solve the above-mentioned technical problems, this utility model provides a whole blood mixing device, comprising:
[0005] The mounting frame is provided with a sliding guide rail extending along a preset direction, and a limiting groove is formed on the mounting frame;
[0006] A connecting tray is movably mounted on the sliding guide rail so that the connecting tray can move along a preset direction on the sliding guide rail, and a mixing shaft is provided on the connecting tray.
[0007] A drive mechanism is connected to the connecting tray, and the drive mechanism is used to drive the connecting tray to reciprocate on the sliding guide rail;
[0008] A mixing block is rotatably connected to the mixing shaft. A positioning mechanism is provided on the mixing block for installing positioning blood collection tubes. A trajectory shaft is also fixedly provided on the mixing block, extending into the limiting groove. When the connecting plate reciprocates on the sliding guide rail, the trajectory shaft reciprocates along the trajectory of the limiting groove so that the mixing block swings back and forth within a set angle range around the mixing shaft.
[0009] As a preferred embodiment of the above technical solution, the drive mechanism includes a drive motor, a synchronous belt, a first synchronous pulley, and a second synchronous pulley. The first and second synchronous pulleys are rotatably mounted on the mounting frame. The synchronous belt is tensioned on the first and second synchronous pulleys. The connecting plate is fixedly connected to the synchronous belt. The drive motor is connected to either the first or the second synchronous pulley.
[0010] As a preferred embodiment of the above technical solution, a reset optocoupler is provided at a preset position of the mounting frame.
[0011] As a preferred embodiment of the above technical solution, a sensing opening is formed on the reset optocoupler, and a protrusion is provided on the connecting plate corresponding to the sensing opening.
[0012] As a preferred embodiment of the above technical solution, the mixing block is rotatably connected to the mixing shaft via a bearing.
[0013] As a preferred embodiment of the above technical solution, a track bearing is provided at the distal end of the track axis, the track bearing is located in the limiting groove, and the outer ring of the track bearing is in contact with the inner wall of the limiting groove.
[0014] As a preferred embodiment of the above technical solution, the limiting groove includes a first straight groove, a second straight groove, and an arc-shaped groove. The first straight groove and the second straight groove are parallel to each other and have a set distance. The first straight groove and the second straight groove extend along the preset direction. The two ends of the arc-shaped groove are respectively connected to the ends of the first straight groove and the second straight groove.
[0015] As a preferred embodiment of the above technical solution, the positioning mechanism includes an anti-detachment plate and an elastic clamping plate.

The two elastic clamping plates are used to clamp the blood collection tube, and the anti-detachment plate is used to support the lower end of the blood collection tube.
[0016] As a preferred embodiment of the above technical solution, the drive motor is fixed on the mounting frame.
[0017] This utility model provides a whole blood mixing device, which includes a mounting frame, a connecting tray, a mixing block, and a driving mechanism. During operation, a positioning mechanism is used to place a blood collection tube containing the test blood sample onto the mixing block. The driving mechanism is then activated to drive the connecting tray to reciprocate on a sliding guide rail. Since the mixing shaft on the connecting tray is rotatably connected to the mixing block, while the trajectory shaft is fixedly connected, the trajectory shaft moves within a limiting groove during the reciprocating motion of the connecting tray. Due to the limiting of the trajectory in the limiting groove, the mixing block can swing back and forth within a certain set angle to mix the blood sample. It can mix single-tube blood samples, which improves the mixing effect and ease of use compared to manual mixing.

DETAILED DESCRIPTION
[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] See Figures 1 to 3 This utility model provides a whole blood mixing device, comprising:
[0025] Mounting frame 10, with a sliding guide rail 40 extending along a preset direction on the mounting frame 10, and a limiting groove 101 opened on the mounting frame 10;
[0026] A connecting tray 50 is movably mounted on a sliding guide rail 40 so that the connecting tray 50 can move along a preset direction on the sliding guide rail 40. A mixing shaft 90 is provided on the connecting tray 50.
[0027] The drive mechanism 20 is connected to the connecting tray 50 and is used to drive the connecting tray 50 to reciprocate on the sliding guide rail 40.
[0028] The mixing block 60 is rotatably connected to the mixing shaft 90. A positioning mechanism 70 is provided on the mixing block 60 for installing the positioning blood collection tube 80. A trajectory shaft 100 is also fixedly provided on the mixing block 60. The trajectory shaft 100 extends into the limiting groove 101. When the connecting plate 50 reciprocates on the sliding guide rail 40, the trajectory shaft 100 reciprocates along the trajectory of the limiting groove 101 so that the mixing block 60 swings back and forth within a set angle range with the mixing shaft 90 as the center.
[0029] This utility model provides a whole blood mixing device, which includes a mounting frame 10, a connecting tray 50, a mixing block 60, and a driving mechanism 20. During operation, a positioning mechanism 70 is used to place a blood collection tube 80 containing the blood sample onto the mixing block 60. The driving mechanism 20 is activated to drive the connecting tray 50 to reciprocate on the sliding guide rail 40. Since the mixing shaft 90 on the connecting tray 50 is rotatably connected to the mixing block 60, while the trajectory shaft 100 is fixedly connected, the trajectory shaft 100 moves in the limiting groove 101 during the reciprocating motion of the connecting tray 50. The limiting groove 101 allows the mixing block 60 to swing back and forth within a certain set angle to mix the blood sample. It can mix single tube blood samples, which improves the mixing effect and ease of use compared to manual mixing.
[0030] In a further embodiment of this invention, the drive mechanism 20 includes a drive motor 201, a synchronous belt 202, a first synchronous pulley 203, and a second synchronous pulley 204.

[0033] In a further embodiment of this invention, a sensing opening is formed on the reset optocoupler 30, and a protrusion 501 is provided on the connecting plate 50 corresponding to the sensing opening.
[0034] In this embodiment, when the connecting plate 50 moves to the preset position, the protrusion 501 extends into the sensing opening, and the drive motor 201 reverses and resets to the initial position.
[0035] In a further embodiment of this invention, the mixing block 60 is rotatably connected to the mixing shaft 90 via a bearing.

[0037] In this embodiment, the outer ring of the track bearing 110 contacts the inner wall of the limiting groove 101, which can effectively prevent friction.
[0038] In a further embodiment of this invention, the limiting groove 101 includes a first straight groove 1011, a second straight groove 1013, and an arc-shaped groove 1012. The first straight groove 1011 and the second straight groove 1013 are parallel to each other and have a set distance. The first straight groove 1011 and the second straight groove 1013 extend along a preset direction. The two ends of the arc-shaped groove 1012 are respectively connected to the ends of the first straight groove 1011 and the second straight groove 1013.
