Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a bracket for collecting Raman spectrum data of blood samples. Background Art

[0002] Raman spectroscopy can be used to detect biomarkers in blood, such as globulin, cholesterol, albumin, lactic acid, and lactate, which are important in clinical diagnosis. Furthermore, Raman spectroscopy has been used to detect specific disease markers in the blood, such as the CA-125 marker in ovarian cancer patients. Currently, Raman spectroscopy technology has been widely used in the testing of blood samples and has demonstrated significant advantages. The technology is capable of testing multiple blood sample types, including whole blood, plasma, and serum.

[0003] During testing, a sampling tube containing a blood sample is placed on the sample stage of a Raman spectrometer. Because Raman spectroscopy can penetrate the sampling tube and non-invasively, periodically, or continuously detect the blood sample within it, a fixture is required to secure the tube. Common fixtures include clamps or tube slots, but these have two major drawbacks: First, the sampling tube must be manually secured and its position and placement adjusted, which is time-consuming and labor-intensive. This manual operation significantly reduces efficiency, especially when long-term or high-frequency operation is required. Second, the laser source's irradiation location (i.e., the data collection point) must be manually adjusted, such as by manually moving or rotating the sampling tube to change the laser's irradiation location on the tube. However, precise adjustment of the sampling tube's position makes it difficult to quantitatively or regularly adjust the data collection point, resulting in inconsistent sample conditions for each measurement, which in turn affects the repeatability and reliability of the data.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] The purpose of the utility model is to provide a bracket for collecting Raman spectroscopy data of blood samples to solve the problems existing in the related technologies.

[0040] Furthermore, the second moving mechanism includes a second moving block 10, a second lead screw 11 and a second motor 12. The second moving block 10 is fixed to the side of the second moving platform 2. The second lead screw 11 is arranged on the side of the third moving platform 3, and the second lead screw 11 extends along the Y direction. One end of the second lead screw 11 is threadedly connected to the second moving block 10, and the other end is connected to the output end of the second motor 12. The second motor 12 can drive the second lead screw 11 to rotate to drive the second moving platform 2 to move along the Y direction, thereby adjusting the position of the sampling tube 19 in the Y direction; specifically, the third moving platform 3 in this embodiment is a square block, and a Y-direction scale identification layer is provided on the side of the third moving platform 3 close to the second moving block 10, which is convenient for reading and recording the position of the sampling tube 19 in the Y direction.

[0041] In this embodiment, if Figure 1 and Figure 3 As shown, the third moving mechanism includes a mounting block 13, a rack 14, a gear 15 and a third motor 16.

The gear 15 and the rack 14 are both installed in the accommodating cavity.

[0042] Furthermore, an opening is provided at the top of the accommodating chamber, and a third slide groove 1301 is provided on the inner wall of the accommodating chamber. The third slide groove 1301 extends along the Z direction. A third slider 1401 is fixed to the side of the rack 14. The third slider 1401 is slidably connected in the third slide groove 1301, so that the rack 14 can move along the Z direction and pass through the top opening of the accommodating chamber, and the top of the rack 14 is fixedly connected to the bottom of the third movable platform 3; the gear 15 is connected to the output end of the third motor 16 and meshes with the rack 14.

[0043] In this embodiment, the rotating mechanism includes a fourth motor, which is fixed in the base 5, and the output end of the fourth motor is arranged upward along the Z direction and connected to the rotating platform 4. The fourth motor can drive the rotating platform 4 to rotate, thereby adjusting the opening direction of the tube wall of the hollow tube 6; specifically, the rotating platform 4 and the base 5 in this embodiment are both cylindrical blocks, and the side of the base 5 is provided with an angle identification layer along the circumferential direction, and a pointer is provided at the position corresponding to the angle identification layer on the side of the rotating platform 4, which is convenient for reading and recording the opening direction of the tube wall of the hollow tube 6; the bottom of the base 5 in this embodiment is also provided with multiple layers of rubber pads 501, which are used for buffering and vibration isolation, making the overall bracket more stable, reducing the influence of vibration on the experimental results, and further ensuring the accuracy of data acquisition.

[0044] It should be noted that the fourth motor in this embodiment can drive the rotating platform 4 to rotate 120° each time. Accordingly, three strip openings 601 are provided on the hollow tube 6 in this embodiment. After the position of the sampling tube 19 in the X direction, the Y direction and the Z direction are adjusted appropriately, the three strip openings 601 of the hollow tube 6 are aligned with the laser 20 in sequence through the rotation of the rotating platform 4, thereby realizing the collection of three data collection points.

[0045] As a possible example, the first motor 9, the second motor 12, the third motor 16 and the fourth motor in this embodiment can all be connected to the controller, and the first mobile platform 1, the second mobile platform 2, the third mobile platform 3 and the rotating platform 4 are controlled by the controller to facilitate the quantitative and constant movement and rotation of the sampling tube 19.

[0046] In this embodiment, the bracket for collecting Raman spectrum data of blood samples also includes a light shield 17, which includes a light shielding cloth coated with a light shielding layer, and a circle of frame is fixed around the edge of the light shielding cloth, and the frame can be bent and deformed to adjust the shape of the light shielding cloth; specifically, the light shield 17 in this embodiment is installed on the first movable platform 1 through a hook 18, and the light shielding cloth of the light shield 17 is coated with a light shielding layer of fluorocarbon material, which has a good light shielding effect. The frame of the light shield 17 is made of aluminum, so that the light shield 17 as a whole has durability and shape plasticity.

[0047] It should be noted that in the Raman spectroscopy experiment, only the spectral data of the area irradiated by the laser 20 is valid, while the non-collection area of the sample may be affected by the surrounding environment or unnecessary background signals. Especially in the case of multi-point collection, the non-collection area of the sample may introduce noise or background noise, affecting the accuracy and reliability of the data. Therefore, the hollow tube 6 is used in this embodiment, which can not only cover the non-collection area of the sample to a certain extent, but also does not affect the acquisition of the spectral signal. For the case where multiple strip-shaped openings 601 are provided on the hollow tube 6, a light shield 17 is also designed in this embodiment. By pinching the light shield 17 to a suitable shape by hand, the non-collection area of the sample can be effectively covered to avoid the generation of interference signals. At the same time, the light shield 17 can also effectively prevent the user from being irradiated by the laser 20, and is safe to use.

[0048] The use process of the support for collecting Raman spectroscopy data of blood samples provided in this embodiment is as follows:

[0049] The bracket is placed below the laser light source 20, and the sampling tube 19 containing the blood sample is inserted into the hollow tube 6. The sampling tube 19 is clamped by the spring piece 602 in the hollow tube 6 to effectively fix the sampling tube 19. Then, the first moving mechanism drives the first moving platform 1 to move in the X direction to adjust the position of the sampling tube 19 in the X direction. The second moving mechanism drives the second moving platform 2 to move in the Y direction to adjust the position of the sampling tube 19 in the Y direction. The third moving mechanism drives the third moving platform 3 to move in the Z direction to adjust the position of the sampling tube 19 in the Z direction. The rotating mechanism drives the rotating platform 4 to rotate to adjust the direction of the tube wall opening of the hollow tube 6, thereby achieving precise adjustment of the position of the sampling tube 19, so that the laser 20 can penetrate the tube wall opening of the hollow tube 6 and enter the sampling tube 19, ensuring that the laser 20 detects the sample in the sampling tube 19. Then, the non-collection area of the sampling tube 19 is covered by the light shield 17, and Raman spectrum data can be collected.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
