Description

Technical Field

[0001] This utility model relates to the field of biomedical testing instrument technology, specifically a bagging device for a reagent sample addition tank. Background Technology

[0002] A reagent dispensing dish is a specialized container or recessed structure used in laboratory or medical testing equipment for the precise dispensing and holding of reagents. Different experiments, and even the same experiment, may involve the batch pipetting of multiple reagents, frequently necessitating the replacement and reuse of dispensing dishes. Generally, a disposable plastic film bag is placed over the dispensing dish to facilitate its reuse.

[0003] In the prior art, the authorized publication number CN204768773U discloses a reagent dispensing slot, which includes a square base and a reagent slot with an open top. The square base surrounds the outer periphery of the reagent slot, and the bottom of the reagent slot is higher than the bottom of the square base. A flange extends outward along the bottom edge of the square base, and a support block extends upward from the flange at the connection between the four corners of the square base and the flange.

[0004] Disposable plastic film bags can be placed over the sample loading slots, allowing for their reuse and avoiding the inconvenience and increased costs associated with frequent slot replacements. However, during each manual removal and placement of the film bag, the operator's gloves are highly susceptible to contact with the reagent-contacting portion of the bag. This contact poses a potential risk of contamination, potentially leading to cross-contamination and affecting the accuracy and reliability of experimental results. Furthermore, the repeated removal and placement of the film bag is cumbersome, increasing the workload for researchers and potentially increasing the risk of contamination due to improper operation, thus impacting the overall efficiency and safety of the experiment. Therefore, a bagging device for reagent loading slots is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a bagging device for a reagent dispensing tank to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bagging device for a reagent dispensing tank, comprising a housing and a dispensing tank, wherein a top cover is rotatably mounted on the upper end of the housing, and a side cover is rotatably mounted on the side wall of the housing, both the top cover and the side cover are equipped with magnetic fasteners, a limiting housing is fixedly mounted on the upper edge of the housing, a bagging assembly is provided inside the housing, the bagging assembly includes a U-shaped frame fixedly mounted inside the housing, a plastic bag body is connected to the U-shaped frame, a pre-reserved opening is provided on the plastic bag body, a tear line is provided at the upper edge of the plastic bag body, and an flaring mechanism is installed inside the housing.

[0007] Preferably, a limit strip is connected to the U-shaped frame, and a locking nut is installed on the U-shaped frame.

[0008] Preferably, the plastic bag body has a small circular hole, and the plastic bag body is connected to the U-shaped frame through the small circular hole. The limiting pressure strip has a through hole, and the limiting pressure strip is connected to the U-shaped frame through the through hole.

[0009] Preferably, both ends of the U-shaped frame are threaded, the locking nut is threadedly connected to the U-shaped frame, and the plastic bag body is restricted to the U-shaped frame by the cooperation of the locking nut and the limiting strip.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a bagging device for a reagent dispensing tank, including a device housing 1 and a dispensing tank 2. A top cover 3 is rotatably installed on the upper end of the device housing 1, and a side cover 4 is rotatably installed on the side wall of the device housing 1. Magnetic buckles 5 are installed on both the top cover 3 and the side cover 4. A limiting housing 101 is fixedly installed on the upper edge of the device housing 1. A bagging assembly 6 is provided inside the device housing 1, and a flaring mechanism 7 is installed inside the device housing 1. Through the cooperation of the bagging assembly 6 and the flaring mechanism 7, the bagging of the dispensing tank 2 can be completed quickly, better meeting the needs of repeated use of the dispensing tank 2 in clinical or scientific research work, improving pipetting efficiency and reducing contamination.

[0023] like Figure 2 and Figure 3As shown, the bagging assembly 6 includes a U-shaped frame 601 fixedly installed inside the equipment housing 1. A plastic bag body 604 is connected to the U-shaped frame 601. The plastic bag body 604 has a reserved opening 605. A tear line 606 is provided at the upper edge of the plastic bag body 604. A limiting strip 602 is connected to the U-shaped frame 601. A locking nut 603 is installed on the U-shaped frame 601. A small circular hole is provided on the plastic bag body 604. The plastic bag body 604 is connected to the U-shaped frame 601 through the small circular hole. A through hole is provided on the limiting strip 602. The limiting strip 602 is connected to the U-shaped frame 601 through the through hole.

[0024] Specifically, the plastic bag body 604 is connected to the U-shaped frame 601, and then, with the cooperation of the limiting strip 602 and the locking nut 603, the plastic bag body 604 can be fixed inside the equipment housing 1. The plastic bag body 604 can be torn along the tear line 606 to remove the sample dispensing slot 2 containing the plastic bag. This facilitates the fitting of a disposable film bag into the sample dispensing slot 2, better meeting the needs of repeated use in clinical or research work, improving pipetting efficiency and reducing contamination.

[0025] like Figure 2 and Figure 4 As shown, the flaring mechanism 7 includes a positioning seat 701 fixedly installed on the inner wall of the equipment housing 1. A limit block 702 is fixedly installed on the top of the positioning seat 701. A movable shaft 707 is rotatably installed on the positioning seat 701. A crossbar 703 is fixedly installed on the movable shaft 707. A connecting groove 704 is fixedly installed at the end of the crossbar 703. A spring plate 705 is fixedly installed in the connecting groove 704. When the crossbar 703 is in a horizontal state, the spring plate 705 is in a bent state. Torsion springs 706 are connected to both ends of the movable shaft 707. A movable hole is opened on the positioning seat 701. The movable shaft 707 is rotatably installed on the positioning seat 701 through the movable hole.

[0026] Specifically, during the entire process of pressing the sample inlet 2 into the equipment housing 1, the crossbar 703 will inevitably be forced to rotate around the movable shaft 707. During this rotation, the spring plate 705 will gradually and slowly unfold as the crossbar 703 rotates, and gradually extend into the interior of the reserved opening 605. As the crossbar 703 continues to rotate, the reserved opening 605 will be gradually expanded under the action of the spring plate 705. This expansion process provides the necessary space for the sample inlet 2 to pass smoothly, allowing the sample inlet 2 to pass through the expanded reserved opening 605 and smoothly enter the interior of the plastic bag body 604. In this way, the bagging work of the sample inlet 2 can be completed quickly and efficiently. After the sample inlet 2 is completely inside the plastic bag body 604, the torsion spring 706 will take effect, twisting the movable shaft 707 to return it to its initial position. Once the movable shaft 707 returns to its original position, it will immediately drive the crossbar 703 and the spring plate 705 to return to their initial state.

[0027] Working principle: Before use, first connect the plastic bag body 604 to the U-shaped frame 601. Then, the plastic bag body 604 can be fixed inside the equipment housing 1 by the cooperation of the limiting pressure strip 602 and the locking nut 603. When in use, first open the top cover 3, and then press the sample filling slot 2 into the equipment housing 1. During the process of pressing the sample filling slot 2 into the equipment housing 1, the crossbar 703 will be forced to rotate around the movable shaft 707. During the rotation of the crossbar 703, the spring plate 705 will slowly unfold and extend into the reserved opening 605. As the crossbar 703 continues to rotate, the reserved opening 605 will be expanded by the spring plate 705, so that the sample filling slot 2 can enter the plastic bag body 604 through the expanded reserved opening 605, quickly completing the bagging work of the sample filling slot 2. After the sample filling slot 2 is completely inside the plastic bag body 604, the torsion spring 706 will twist the movable shaft 707 to reset. After the movable shaft 707 resets, it will drive the crossbar 703 and the spring plate 705 to reset. Then, the plastic bag body 604 can be torn along the tear line 606, thereby removing the sample tray 2 containing the plastic bag from the side cover 4.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
