Description

Technical Field

[0002] In the field of medical testing, there is a need for efficient, precise, and manual methods to mix blood samples and additives in blood collection tubes, in order to improve work efficiency and reduce human error. This demand is particularly evident when processing large volumes of samples, making blood collection tube processing systems essential. Currently, manual shaking of blood collection tubes is the primary method for mixing the blood sample and additives. However, the force, duration, frequency, and method of hand shaking vary greatly, making it impossible to guarantee the mixing effect and the extent of impact on the blood sample. Equipment on the market that can perform the function of mixing blood samples and additives in blood collection tubes is of inconsistent quality, making it difficult to guarantee stable and reliable performance. These devices often have broad functions, accommodating various laboratory uses such as shaking and centrifugation, and are not specifically designed for thorough mixing of blood samples and additives in blood collection tubes. Therefore, they may not achieve the required precision and efficiency in mixing and do not conform to the operating methods specified in the blood collection tube instructions.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this embodiment, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0046] In this embodiment, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly.

[0048] The following is combined with Figures 1-6 This invention describes a continuous shaking system for blood collection tubes. The system includes: a housing 1, a first driving device 2, a second driving device (not shown in the figure), a first tube compartment 3, and a second tube compartment 4.

[0049] The housing 1 is provided with a rotating shaft 5; a first driving device 2 is located inside the housing 1; a second driving device is located inside the housing 1; a first tube 3 is connected to the first driving device 2 and is rotatably mounted on the first part of the rotating shaft 5 under the drive of the first driving device 2; a second tube 4 is connected to the second driving device and is rotatably mounted on the second part of the rotating shaft 5 under the drive of the second driving device.

[0050] Specifically, the rotating shaft 5 is rotatably mounted on the housing 1, and the housing 1 has mounting areas for the first tube compartment 3 and the second tube compartment 4 to rotate. On both sides of the mounting area, the housing 1 has mounting portions for mounting the rotating shaft 5. These mounting portions are protruding parts of the housing 1, thereby forming the aforementioned mounting area between the two mounting portions.

[0051] The first drive device 2 and the second drive device are respectively installed inside the housing 1. The first tube chamber 3 and the second tube chamber 4 are respectively mounted on the rotating shaft 5 and can rotate independently on the rotating shaft 5. The first drive device 2 provides power for the rotation of the first tube chamber 3, and the second drive device provides power for the rotation of the second tube chamber 4, thus providing rotational power to the two tube chambers respectively through the two drive devices.

[0052] Both the first chamber 3 and the second chamber 4 can clamp and rotate the blood collection tubes 11. The first chamber 3 and the second chamber 4 rotate independently, and their operation does not interfere with each other. In use, medical personnel place one or a group of blood collection tubes 11 into the first chamber 3 and activate the first drive device 2 to shake the blood collection tubes 11. For the second or second group of blood collection, the second or second group of blood collection tubes 11 are placed into the second chamber 4, and the second drive device is activated to shake the blood collection tubes 11. At this point, the blood collection tubes 11 in the first chamber 3 have been shaken and can be removed. Thus, the two chambers achieve continuous shaking of the blood collection tubes 11, improving work efficiency.

[0053] It should be understood that since the first drive device 2 and the second drive device have the same structure, only the first drive device 2 is shown schematically in the figure.

[0054] Specifically, the shell 1 is a cuboid shell 1, which can be composed of side walls, top walls and bottom walls, and can be connected by bolts to form the shell 1 structure.

[0055] Preferably, the rotation angle of the first driving device 2 and the second driving device is 0-180°, and as needed, the first driving device 2 and the second driving device drive the first tube 3 and the second tube 4 to rotate, and the blood collection tube 11 rotates several times. Generally, the number of times the blood collection tube 11 rotates should be selected according to the requirements in the instruction manual, usually 3 times, 5 times or 8 times.

[0056] In practical use, this invention is suitable for single-handed operation, which allows medical workers to stabilize the blood collection needle with one hand while placing the blood collection tube 11 on the continuous shaking system with the other hand during blood collection, saving blood collection time, improving blood collection efficiency, and avoiding damage to the collected blood sample caused by improper shaking operation.

[0057] This utility model provides a continuous shaking system for blood collection tubes, comprising: a housing 1, a first driving device 2, a second driving device, a first tube compartment 3, and a second tube compartment 4. The housing 1 is provided with a rotating shaft 5; the first driving device 2 is located inside the housing 1; the second driving device is located inside the housing 1; the first tube compartment 3 is connected to the first driving device 2 and is rotatably mounted on a first portion of the rotating shaft 5 under the drive of the first driving device 2; the second tube compartment 4 is connected to the second driving device and is rotatably mounted on a second portion of the rotating shaft 5 under the drive of the second driving device. This utility model provides a continuous shaking system for blood collection tubes. Two driving devices provide power for the rotation of two tube compartments, replacing manual rotation of the blood collection tubes. This frees medical workers from repetitive labor, standardizes and regulates the shaking operation of the blood collection tubes, and ensures effective shaking. It is suitable for one-handed operation, allowing medical workers to stabilize the blood collection needle with one hand while placing the blood collection tube on the shaking system with the other, saving time and improving efficiency. It also avoids damage to the collected blood sample caused by improper shaking. The independently rotating first and second tube compartments 3 and 4 enable continuous shaking of the blood collection tubes.

[0058] In one embodiment of this utility model, the continuous shaking system for blood collection tubes further includes: a first transmission device 6 and a second transmission device. The first transmission device 6 is connected to the first drive device and the first tube compartment; the second transmission device is connected to the second drive device and the second tube compartment 4. Specifically, the two transmission devices respectively transmit the power of the drive device to the corresponding tube compartment; and the movements of the two transmission devices are independent of each other and do not affect each other.

[0059] In one embodiment of this utility model, the first transmission device 6 includes: a first driving sprocket 61, a first chain 62, and a first driven sprocket 63. The first driving sprocket 61 is connected to the output shaft of the first drive device 2; one end of the first chain 62 is connected to the first driving sprocket 61; the first driven sprocket 63 is connected to the first tube cassette 3 and to the other end of the first chain 62. Similarly, the second transmission device includes: a second driving sprocket, a second chain, and a second driven sprocket. The second driving sprocket is connected to the output shaft of the second drive device; one end of the second chain is connected to the second driving sprocket; the second driven sprocket is connected to the second tube cassette 4 and to the other end of the second chain. In this embodiment, the transmission devices all employ a sprocket and chain transmission method to transmit the rotation of the drive device to the tube cassette. Of course, other methods, such as belt and pulley transmission methods, can also be used according to actual needs.

[0060] It should be understood that since the first transmission device 6 and the second transmission device have the same structure, only the first transmission device 6 is shown schematically in the figure, and the second transmission device is a symmetrical design with respect to the first transmission device 6.

[0061] In one embodiment of this utility model, the rotating shaft 5 comprises two parts: a first rotating shaft 51 and a second rotating shaft 52. The first rotating shaft 51 has a hollow structure, a first driven sprocket 63 is connected to one end of the first rotating shaft 51, and a first tube 3 is fixed to the outer surface of the first rotating shaft 51. The second rotating shaft 52 has an insertion end that is inserted into the hollow structure, and the second rotating shaft 52 is rotatably connected to the first rotating shaft 51. A second driven sprocket is connected to one end of the second rotating shaft 52, and a second tube 4 is fixed to the outer surface of the second rotating shaft 52. In this embodiment, the rotating shaft 5 is composed of two parts: the first rotating shaft 51 and the second rotating shaft 52. The first rotating shaft 51 has a hollow structure, and the insertion port of the second rotating shaft 52 has a smaller diameter, allowing it to be inserted into the first rotating shaft 51 and achieving rotational engagement between the two, ensuring that the rotation of the first tube 3 and the second tube 4 is independent of each other. The outer surface of the first rotating shaft 51 is the mounting surface of the first tube chamber 3, and the first rotating shaft 51 drives the first tube chamber 3 to rotate; the outer surface of the second rotating shaft 52 is the mounting surface of the second tube chamber 4, and the second rotating shaft 52 drives the second tube chamber 4 to rotate. Preferably, the second rotating shaft 52 consists of two parts with a smaller diameter and a larger diameter. The smaller diameter part is the insertion end, and the larger diameter part is the mounting surface of the second tube chamber 4. After the insertion end is inserted into the first rotating shaft 51, the exposed portions of the first rotating shaft 51 and the second rotating shaft 52 have the same tube diameter.

[0062] Correspondingly, the first tube compartment 3 and the second tube compartment 4 are provided with through holes that are adapted to the first rotating shaft 51 and the second rotating shaft 52. The shape and size of the through holes are adapted to the rotating shaft 5 to ensure that when the rotating shaft 5 rotates, the tube compartments rotate accordingly.

[0063] In one embodiment of this utility model, both the first tube compartment 3 and the second tube compartment 4 are provided with multiple tube clamps. Preferably, as shown below... Figure 1 As shown, both the first tube compartment 3 and the second tube compartment 4 have four tube clamps, which can simultaneously shake the four blood collection tubes 11.

[0064] In one embodiment of this utility model, the inner wall of the tube clamp has an elastic clamping portion. Preferably, the elastic clamping portion of the inner wall of the tube clamp can be made of flexible medical silicone material, which ensures the clamping of the blood collection tube 11 on the one hand, and does not damage the blood collection tube 11 on the other hand.

[0065] In one embodiment of the present invention, the blood collection tube continuous shaking system further includes a power supply 7, which is electrically connected to the first driving device 2 and the second driving device respectively, to provide power to the first driving device 2 and the second driving device.

[0066] In one embodiment of the present invention, the blood collection tube continuous shaking system further includes a charging port 8, which is disposed on the housing 1 and electrically connected to the power supply 7, and can charge the power supply 7 through the charging port 8.

[0067] In one embodiment of this utility model, both the first driving device 2 and the second driving device are stepper motors, which have advantages such as high-precision positioning, rapid start-stop capability, and ease of control. Of course, other driving components can be used instead, depending on actual needs.

[0068] In one embodiment of this utility model, the blood collection tube continuous shaking system further includes a display screen 9, which is disposed on the housing 1. The display screen 9 can display the number of rotations of the blood collection tube 11 and the battery level.

[0069] In one embodiment of this utility model, the blood collection tube continuous shaking system further includes a control knob 10 and a rotary encoder. The control knob 10 is rotatably mounted on the housing 1; the rotary encoder is located inside the housing 1 and connected to the control knob 10, and is used to control the rotation frequency of the first drive device 2 and the second drive device. Specifically, the blood collection tube shaking system is also equipped with a control circuit board, which can use a PLC or frequency converter to control the stepper motor. In this embodiment, the rotation frequency of the first tube compartment 3 and the second tube compartment 4 can be set by manually rotating the control knob 10. The rotary encoder converts this into an electrical signal, and the control circuit board controls the rotation frequency of the stepper motor. Two control knobs 10 and two rotary encoders are configured, corresponding to control the first drive device 2 and the second drive device. In this embodiment, the default rotation angle for one rotation is 180°, that is: one flip reverses the blood collection tube 11, a second flip resets the blood collection tube 11, and the above reversal and reset is counted as one rotation. For example, if the control knob 10 is rotated to the "5 times" setting, the stepper motor will drive the pipe clamp to rotate 5 times. The rotary encoder is connected to the control knob 10. The number of rotations (e.g., 3 times, 5 times, and 8 times) can be selected by using the control knob 10. After the scale line on the control knob 10 is aligned with the corresponding number of rotations, the display screen 9 will also display the number of rotations.

[0070] In practical use of the continuous shaking system for blood collection tubes of this utility model, for example:

[0071] When collecting blood samples from patients for routine blood tests, EDTA (ethylenediaminetetraacetic acid) anticoagulant tubes are usually used. The caps are generally purple. According to the instructions on the blood collection tube, the tube should be inverted 180° and shaken 5 times. After collecting the blood sample, the medical worker inserts the needle into the next blood collection tube. When collecting blood, the previously collected blood collection tube is placed in the compartment of the continuous shaking system. The control knob 10 is turned to the corresponding number of times, and the shaking operation is started when the control knob 10 is pressed. The shaking operation can be performed simultaneously after the next blood collection tube is collected without waiting for the equipment to stop.

[0072] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
