Description

Technical Field

[0001] This utility model relates to the field of blood collection tube shaking technology, specifically a device based on the principle of figure-eight shaking of blood collection tubes. Background Technology

[0002] Due to different testing requirements, blood collection tubes contain different reagents, including anticoagulants, procoagulants, and those without added reagents. Depending on the test, after collecting the sample, the blood collection tube needs to be shaken to promote the full mixing of the reagent and the blood sample. Strictly speaking, the number of times to shake the tube also varies depending on the testing requirements.

[0003] Most blood collection tube mixing devices currently on the market are roller mixing devices, which achieve horizontal rolling mixing of the blood collection tube samples, or turntable-type rotating mixing devices, which cause the blood collection tube samples to sway up and down as the turntable rotates. Both of these mixing methods can mix multiple sample tubes simultaneously. However, neither of these devices can achieve mixing for different durations and angles according to the needs of the samples. To solve this problem, and to address the mixing requirements of different types of blood collection tubes, a blood collection tube mixing device is needed to solve the aforementioned issues. Summary of the Invention

[0004] The purpose of this invention is to provide a blood collection tube shaking device that enables different types of blood collection tube samples to be shaken in different ways.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A blood collection tube shaking device comprises an outer support plate, a feeding detection mechanism, a shaking and fixing mechanism, a shaking power mechanism, a control power mechanism, a control plate, and a discharge port. Furthermore, the external support plate consists of two parts: an upright plate and a base plate. The base plate is located at the bottom of the device and serves as ground support. Most other mechanisms are installed and fixed on the base plate. The upright plate is installed on one side of the base plate and serves as vertical support.

[0006] Furthermore, an infeed detection mechanism is installed at the top of the device to check whether a blood collection tube has entered the shaking device and to determine the color of the blood collection tube. Specifically, it includes the following structural components: The color recognition sensor mounting plate is installed on the upper part of the upright plate; The color recognition sensor is installed on the color recognition sensor mounting plate near the device inlet. It is used to determine the color of the blood collection tube cap that needs to be shaken and feeds it back to the control board, thereby determining the angle and number of shakes for the blood collection tube. The first sensor mounting plate is installed on the upper part of the upright plate; The first sensor is mounted on the first sensor mounting plate, near the device inlet and opposite the color recognition sensor, to determine whether a blood collection tube has entered the shaking device, and to eliminate interference from other items. Furthermore, the shaking and fixing mechanism is used to fix the blood collection tube during the shaking process, and specifically includes the following structural components: The sliding connector is located at one end of the mechanism, on the side away from the vertical plate, to achieve connection with the control power mechanism; One end of the dragging component is connected to the sliding connector, and the other end is connected to the sleeve, which is used to drag the sleeve to change its angle; The tube limiting component is installed on the drag component to prevent the vacuum blood collection tube from falling off during rotation; The tube sleeve is used to hold the blood collection tubes; one end is connected to the dragging component, and the other end is connected to the rotating component.

Furthermore, the shaking power mechanism provides power for the rotation of the shaking fixing mechanism, and specifically includes the following structural components: The bearing housing is fixed to the vertical plate and is equipped with a No. 1 flange bearing inside. One end of the No. 1 rotating shaft is connected to the No. 1 flange bearing and can rotate freely, while the other end is connected to the rotating component.

The synchronous pulley is connected to the synchronous belt pulley via a synchronous belt. When the first motor rotates, it drives the synchronous pulley to rotate, which in turn drives the synchronous belt to rotate, which in turn drives the synchronous belt pulley to rotate, and thus drives the No. 1 rotating shaft to rotate. Furthermore, the control power mechanism provides power for the angle change of the shaking and fixing mechanism, stretching the shaking and fixing mechanism to different angles. Specifically, it includes the following structural components: The second motor mounting plate is fixed to the base plate, and the second motor and the third sensor are mounted on the second motor mounting plate.

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are merely for explaining this utility model and are not intended to limit it.

[0012] The specific implementation of this utility model will be described in detail below with reference to specific examples.

[0013] In one example of this utility model, see Figure 1-6The device includes an outer support plate 1, on which are mounted a feeding detection mechanism 2, a shaking and fixing mechanism 3, a shaking power mechanism 4, a control power mechanism 5, a control plate 6, and a discharge port 7. The feeding detection mechanism 2 is fixed at the upper end of the device, near the blood collection tube inlet, to check for the presence of blood collection tubes and to shield against interference. The shaking and fixing mechanism 3 is installed at the lower end of the feeding detection mechanism 2, receiving the blood collection tubes fed by the feeding detection mechanism 2, and is responsible for fixing the blood collection tubes during figure-eight shaking. The shaking power mechanism 4 is for shaking and fixing... Mechanism 3 provides power for the figure-eight shaking of the blood collection tubes; the control power mechanism 5 provides control power for changing the position of the shaking fixing mechanism 3, realizing the switching between the receiving position, shaking position and tube outlet position of the blood collection tubes, and the shaking position is determined according to the type of blood collection tubes; the control board 6 is the core control unit of the entire mechanism, controlling the sequential operation of each mechanism; the discharge port 7 is located below the shaking fixing mechanism 3, receiving the blood collection tubes after figure-eight shaking and outputting the shaking device, thereby completing the different figure-eight shaking functions of blood collection tubes with different caps.

[0014] Furthermore, the feeding detection mechanism 2 includes a color recognition sensor 201 and a first sensor 203, both of which are fixed at the feeding port of the shaking device and are symmetrically distributed. The first sensor 203 is responsible for checking whether there is a blood collection tube being fed in and for making a preliminary judgment and eliminating interference. The color recognition sensor 201 identifies the color of the cap of the blood collection tube being fed in and feeds it back to the control board 6, thereby determining the number of shaking cycles and the shaking angle of the blood collection tube.

[0015] The shaking and fixing mechanism 3 is equipped with a tube limiting member 303, a tube sleeve 304, a rotation detection plate 306, and a second sensor 307. The diameter of the tube sleeve 304 is slightly larger than the diameter of the blood collection tube body but smaller than the diameter of the blood collection tube cap, thereby allowing the blood collection tube to enter and exit freely without missing any tubes. The tube limiting member 303 is inclined. When the shaking and fixing mechanism 3 moves the blood collection tube, the blood collection tube cap may fall downwards at times. The tube limiting member 303 blocks the blood collection tube cap to prevent the blood collection tube from falling off. When the shaking and fixing mechanism 3 moves, it drives the rotation detection plate 306 to rotate. The number of rotations of the shaking and fixing mechanism 3 is determined by the number of rotations of the rotation detection plate 306 detected by the second sensor 307.

[0016] The control power mechanism 5 includes a second motor 501, a third sensor 503, a swing arm 504, a swing arm detection component 505, a sliding component 508, and a No. 2 flange bearing 509. The control power mechanism 5 is connected to the shaking and fixing mechanism 3 via the sliding component 508 and the No. 2 flange bearing 509. The second motor 501 drives the sliding component 508 to move left and right through various connecting mechanisms, thereby driving the shaking and fixing mechanism 3 to move left and right, achieving three position changes: the receiving position, the shaking position, and the tube exit position. The shaking position is determined according to the type of vacuum blood collection tube. The swing arm 504 is mounted on the shaft of the second motor 501. The swing arm detection component 505 is mounted on the swing arm 504. The third sensor 503 determines the position of the shaking and fixing mechanism 3 by detecting the swing arm detection component 505. The position detected by the third sensor 503 is the zero point of the shaking position; other positions are determined by the number of motor pulses.

[0017] Furthermore, the shaking device, through the control panel 6, collects the color of the blood collection tube cap from the feeding detection mechanism 2 to determine the type of blood collection tube. This, in turn, determines the shaking angle and number of rotations of the blood collection tube, thereby controlling the cooperation of other components to complete the shaking function of the blood collection tube. This device is simple in structure, practical, and widely applicable, and can achieve thorough mixing of the blood collection tube.

[0018] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
