Description

Technical Field

[0001] The utility model relates to the technical field of analytical detection devices, and particularly relates to a pipette tip protection device for analyzer detection. Background Technique

[0002] Existing analyzers include a sample needle, a pipette tip storage device, reagents, a driving mechanism, a control unit, etc. During the detection process of the instrument, the movement trajectory has been set during the process of the sample needle picking up the pipette tip, sampling, and adding the sample.

Therefore, during sampling, it is easy for the sample to drip onto the unused pipette tips, which may lead to cross-contamination between the pipette tips, and is not conducive to subsequent analysis and detection. At the same time, there is easy shaking between the analyzer and the reagent tube, which is not conducive to the device for sampling operation.

[0026] Embodiment, please refer to Figures 1-3 The present invention provides a technical solution:

[0027] A pipette tip protection device for analyzer detection, comprising an analyzer main body 1 and a sample needle 2 arranged above the analyzer main body 1. A placement hole 3 is opened on the top surface of the analyzer main body 1. An installation ring seat 4 is fixedly installed inside the placement hole 3. A reagent tube 5 is arranged inside the installation ring seat 4. An installation cavity 401 is opened inside the installation ring seat 4. A support compression spring 402, a limit plate 403 and a clamping ball 404 are respectively arranged inside the installation cavity 401. A pipette tip seat 6 is fixedly installed on the left side of the analyzer main body 1. A pipette tip 601 is embedded on the top of the pipette tip seat 6. A protection mechanism 7 is arranged above the pipette tip 601;

[0028] It should be noted that the sample needle 2 is connected to the analyzer main body 1 through an automatic pipetting device;

[0029] Specifically, the placement holes 3 are equidistantly distributed left and right on the top surface of the analyzer main body 1. The installation cavities 401 are annularly and equidistantly arranged on the outer surface of the installation ring seat 4. One end of the support compression spring 402 is fixed to the inner wall of the installation cavity 401, and the other end thereof is fixed to one side of the limit plate 403. The other side of the limit plate 403 is fixed to the outer surface of the clamping ball 404, and its outer surface is slidably attached to the inner wall of the installation cavity 401. The end of the clamping ball 404 away from the limit plate 403 penetrates through the inner wall of the installation cavity 401 and contacts the outer surface of the reagent tube 5;

[0030] In this implementation scheme, the clamping ball 404 is made of rubber material. Through the setting of the support compression spring 402, it elastically supports the limit plate 403, enabling the limit plate 403 to slide along the inner wall of the installation cavity 401, ensuring a firm contact between the clamping ball 404 and the reagent tube 5, thereby achieving the function of fixing the reagent tube 5 and meeting the needs of the user.

[0031] Specifically, there are multiple pipette tips 601, and the inner walls of the multiple pipette tips 601 are all matched with the sample needle 2;

[0032] In this implementation scheme, the pipette tip 601 is mainly used to be sleeved outside the sample needle 2 to facilitate the sample needle 2 to sample the sample in the reagent tube 5.

[0033] In this embodiment, please refer to Figure 1 and Figure 3 , the protection mechanism 7 includes a protective cover 701 and a lower fixing block 702. The protective cover 701 is arranged on the top surface of the pipette tip seat 6, and an upper fixing block 703 is fixedly installed on the left side thereof. The lower fixing block 702 is fixedly arranged on the left side surface of the pipette tip seat 6, and a low-speed motor 704 is fixedly installed at the bottom thereof. A shaft body 705 is arranged on the top of the lower fixing block 702;

[0034] Specifically, the bottom surface of the protective cover 701 is flush with the top surface of the suction head seat 6. The bottom end of the shaft body 705 is rotatably connected to the top surface of the lower fixing block 702 through a bearing, and its top end fixedly penetrates through the bottom surface of the upper fixing block 703. The output end of the low-speed motor 704 penetrates through the bottom surface of the lower fixing block 702 and is fixedly connected to the bottom end of the shaft body 705;

[0035] In this embodiment, the low-speed motor 704 is mainly used to rotate the shaft body 705, so that the protective cover 701 can contact or disengage from the suction head seat 6, thereby playing a role in shielding and protecting the suction head 601.

[0036] The working process of the present utility model: When using a suction head protection device for an analyzer detection, place the reagent tube 5 inside the mounting ring seat 4. At this time, the reagent tube 5 contacts the clamping ball 404 and causes it to move towards the inside of the mounting cavity 401. Then, the limiting plate 403 squeezes the supporting compression spring 402 along the inner wall of the mounting cavity 401. During the squeezing process, the supporting compression spring 402 gradually contracts and generates elastic potential energy. This elastic potential energy acts on the clamping ball 404 through the limiting plate 403, so that the clamping ball 404 forms a fitting contact with the reagent tube 5, thereby ensuring the stability of the reagent tube 5. Further, driven by the low-speed motor 704, the shaft body 705 rotates between the bearing and the lower fixing block 702, and the upper fixing block 703 rotates with the rotation of the shaft body 705. Thus, the contact or separation between the protective cover 701 and the suction head seat 6 is realized, the protection of the suction head 601 is realized, and the use requirements of the detection personnel are met.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
