Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an arc-shaped sample holder compatible with sample tubes of different diameters. Background Technology

[0002] In medical devices, the main function of the sample management unit is to manage the samples to be tested. This utility model relates to a sample rack, which is part of the sample management unit. Its main function is to place the samples to be tested and work with other parts to complete the corresponding testing process.

[0003] In actual use, when the sample holder is not equipped with a sample tube adapter, there is a gap between the sample tube and the opening of the sample holder. This will first cause the sample tube to shake and rotate in the sample holder, especially when the sample holder rotates at high speed. Secondly, the sample tube will also tilt slightly between the sample holders, which is not conducive to the accurate positioning of the sample tube in the instrument.

[0004] To address the aforementioned issues, an arc-shaped sample holder compatible with sample tubes of different diameters is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an arc-shaped sample holder that can adapt to various sample tubes and is compatible with sample tubes of different diameters.

[0006] This utility model is achieved through the following technical solution: an arc-shaped sample holder compatible with sample tubes of different diameters, including a sample holder and a sample tube adapter. The upper surface of the sample holder is provided with multiple mounting recesses. The sample tube adapter is used to install and limit the sample tubes. The sample tube adapter is provided with multiple grippers for limiting and guiding the sample tubes. The sample tube adapter is provided with mounting buckles. The sample tube adapter is connected to the sample holder through the mounting buckles.

[0007] Preferably, the gripper includes an upper guide gripper and a lower guide gripper. The upper guide gripper is located inside the sample tube adapter near the top, and the lower guide gripper is located inside the sample tube adapter near the bottom. Both the upper and lower guide grippers are elastically connected to the sample adapter.

[0008] Preferably, the upper guide gripper and the lower guide gripper are arranged in a circumferential shape inside the sample tube adapter, and the number of grippers is two or more, preferably three.

[0009] Preferably, the mounting buckle and the sample tube adapter are integrally formed and elastically positioned together. The bottom of the mounting recess is provided with a slot, which, through the interlocking of the slot and the mounting buckle, fixes the sample tube adapter and the sample holder relatively.

[0010] Preferably, a sample tube scanning notch is provided between the mounting recess and the outer wall of the sample holder. The notch is located at the corresponding position of the sample tube adapter and the sample tube scanning notch. The markings on the placed sample tubes should correspond to the sample tube scanning notch.

[0011] Preferably, the top of the sample tube adapter is provided with an anti-rotation component, and the two ends of the anti-rotation component extend downwards along the notch on the sample tube adapter by a short distance, with the downward distance between the two ends of the anti-rotation component corresponding to the scanning notch of the sample tube.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Currently, sample racks directly adapt to sample tubes or are matched with sample tube adapters. Due to the limitations of the sample rack itself or a single sample tube adapter, the types of sample tubes they can be compatible with are limited. This invention enables the sample rack to be compatible with multiple sample tube adapters, thereby achieving compatibility with a wider variety of sample tubes of different diameters.

[0014] 2. In response to defects such as gaps between the sample tube adapter and the sample tube, insecure clamping, and easy tilting, the sample tube adapter in this case has two or more sets of clamps, which are evenly arranged in the circumferential direction. While having a good centering function, different sets of clamps can achieve functional division. That is, each set of clamps can both guide the sample tube and hold the sample tube. Through the cooperation of such multiple sets of clamps, it can achieve compatibility with various sample tubes, while ensuring that there are no gaps between the sample tube and the adapter and that the sample tube is not tilted.

[0021] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1

[0023] like Figure 1-5 As shown, an arc-shaped sample holder compatible with sample tubes of different diameters includes a sample holder 1 and a sample tube adapter 2. The sample tube adapter 2 is used to limit the installation of the sample tubes. The sample holder 1 is circular in shape, and its upper surface has multiple mounting recesses 8, which are adapted to fit the sample tube adapter 2. Furthermore, multiple numerical labels 9 are arranged sequentially on the top of the sample holder 1, and these numerical labels correspond to the multiple mounting recesses 8.

[0024] The sample tube adapter 2 has multiple upper guide claws 4 located near the top and multiple lower guide claws 5 located near the bottom. Both the upper and lower guide claws 4 and 5 are elastically connected to the sample tube adapter 2. The multiple upper and lower guide claws 4 and 5 are evenly arranged circumferentially. While providing good centering, different groups of claws can perform functional divisions; each group can both guide and hold the sample tube. This multi-group claw arrangement ensures compatibility with various sample tubes while maintaining a gap-free connection between the sample tube and the sample tube adapter 2, and prevents the sample tube from tilting.

[0025] The sample tube adapter 2 is installed in the mounting recess 8 by insertion, and the sample tube adapter 2 has a mounting buckle 6 on the side wall near the bottom. The mounting buckle 6 is elastically connected to the sample tube adapter 2. The bottom of the mounting recess 8 has a slot (not shown in the figure). The mounting buckle 6 and the slot correspond to each other. The sample tube adapter 2 and the sample holder 1 can be relatively fixed by the cooperation of the mounting buckle 6 and the slot.

[0026] When it is necessary to remove sample tube adapter 2, refer to the attached document. Figure 4 By pressing the two mounting buckles 6, the mounting buckles 6 are disengaged from the slots, and then the sample tube adapter 2 and the sample holder 1 can be disengaged by lifting it upwards.

[0027] When installing the sample tube adapter 2, simply align the sample tube adapter 2 with the mounting recess 8 and insert it into the mounting recess 8. Installation is complete when the mounting buckle 6 aligns with the slot. This design ensures compatibility between the sample holder 1 and various sample tube adapters 2, while also allowing for quick disassembly and installation, facilitating easy replacement of the sample tube adapter 2 by users or maintenance personnel.

[0028] A sample tube scanning notch 3 is provided between the mounting recess 8 and the outer wall of the sample holder 1. The sample tube scanning notch 3 is used to facilitate the operator's identification of the markings affixed to the sample tubes. The sample tube adapter 2 has a corresponding notch at the same position as the sample tube scanning notch 3. When placing the sample tube in the sample tube adapter 2, the markings affixed to it should be aligned with the notch on the sample tube adapter 2 to facilitate subsequent identification of the sample tube by the operator.

[0029] The top of the sample tube adapter 2 is provided with an anti-rotation member 7. Both ends of the anti-rotation member 7 extend downward a short distance along the notch on the sample tube adapter 2. During the process of installing the sample tube adapter 2 in the mounting recess 8, the short distance that the anti-rotation member 7 extends downward abuts against the side walls on both sides of the sample tube scanning notch 3. Thus, the anti-rotation member 7 can prevent the sample tube adapter 2 from rotating in the mounting recess 8.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
