Description

Technical Field

[0001] This utility model relates to the field of biological sample testing technology, and in particular to a biological sample testing consumable loading device. Background Technology

[0002] In the field of biosample testing, testing equipment is crucial for accurate sample analysis. With continuous technological advancements, biosample testing technology has developed rapidly, enabling more precise and efficient results, which is of paramount importance for disease diagnosis and scientific research. Advanced testing technologies allow for earlier detection of potential disease risks, providing patients with timely treatment options and promoting further development in bioscience. The biosample testing process involves numerous steps, among which sample pipetting, extraction, and mixing with diluents are key. These operations rely heavily on various consumables, such as tippers, diluent bottles, and mixing cups. Therefore, the rational layout and management of these consumables has become a key focus in this field.

[0003] In traditional biological sample testing, to meet the requirements of pipetting samples and diluents for extraction and mixing in a mixing cup, most methods employed a method of distributing and fixing consumables. In this method, each consumable is fixed in a different position, requiring the pipetting device to move significantly in all directions to extract the sample and diluent. Furthermore, because the consumables are distributed, each one occupies a considerable amount of space, resulting in a large overall footprint. Moreover, retrieving these dispersed consumables requires operators to search and retrieve them from different locations, making the process inconvenient and often time-consuming.

[0030] This utility model discloses a biological sample testing consumable loading device, such as... Figure 1 and Figure 2 As shown, the device includes a storage platform 1, a guide rail 2, a slider 3, a storage base 4, a bracket 5, a tray 8, a storage box 10, and a drive assembly 12. The guide rail 2 is positioned above the storage platform 1, and the slider 3 on the guide rail 2 is connected to the storage base 4. The bracket 5, tray 8, and storage box 10 are mounted on the storage base 4. The drive assembly 12 drives the storage base 4 to move along the guide rail 2, achieving the effects of facilitating the movement and management of consumables, improving extraction efficiency, reducing equipment size, and lowering the error rate. This effect is achieved because the drive assembly 12 allows the storage base 4 to move the consumables, facilitating retrieval, and the centralized arrangement of consumables helps shorten the pipetting path.

[0031] Specifically, slider 3 is generally a block structure with an internal groove that fits the guide rail 2. The groove edge has a lubricating layer to reduce friction with the guide rail 2. The connection structure between slider 3 and guide rail 2 is the cooperation between the groove and the track body. The groove is tightly locked onto the track body, ensuring that slider 3 can slide smoothly on guide rail 2.

[0032] The bin bottom plate 4 is a flat structure, typically made of aluminum alloy, which is lightweight and high-strength. The bin bottom plate 4 is bolted to the top of the slider 3, ensuring synchronized movement. The bin bottom plate 4 has pre-drilled holes and mounting positions for the bracket 5, tray 8, and bin 10, facilitating the installation of each component. Alternatively, the bin bottom plate 4 can be made of stainless steel for better corrosion resistance.

[0033] The bracket 5 is frame-shaped and used to secure the tip box 6. The bracket 5 is made of plastic, possessing a certain degree of elasticity and toughness to cushion external impacts. The bracket 5 is connected to the bottom plate 4 by welding or bolts to ensure a stable connection. The tip box 6 is a square box with multiple compartments inside for storing tip heads 7. The tip head 7 is a slender tubular structure made of plastic, with a sharp tip for easy liquid absorption.

[0034] The tray 8 is a shallow dish, also made of plastic. The tray 8 is connected to the bracket 5 by bolts or clips for easy disassembly and installation. The mixing cup 9 is a cup-shaped container with multiple mixing holes 13 inside. Each tip 7 corresponds one-to-one with a mixing hole 13, ensuring accurate transfer of liquid into the mixing hole 13 during pipetting.

[0035] The container 10 is made of plastic or metal. The container 10 is fixedly connected to the bracket 5 by bolts. The diluent bottle 11 is a bottle-shaped container, available in different sizes and capacities, used to store diluents.

[0036] The drive assembly 12 includes a drive motor 121, a motor plate 122, a drive gear 123, a belt 124, and a driven gear 125. The drive motor 121 is a stepper motor, capable of precisely controlling the rotation angle and speed. The motor plate 122 is a metal plate used to fix the drive motor 121 and is connected to the bin platform 1 by bolts. The drive gear 123 is connected to the output shaft of the drive motor 121 by a key, transmitting the motor's power to the belt 124. The belt 124 is typically a synchronous belt, offering good transmission performance and stability. The driven gear 125 is connected to the drive gear 123 via the belt 124, forming a transmission system. The belt 124 pressure plate is a metal plate, connected to the bin bottom plate 4 by bolts, and also interconnected with the belt 124. When the belt 124 is in operation, the belt 124 pressure plate can drive the bin bottom plate 4 to move along the guide rail 2.

[0037] A roller seat 16 is also provided at the bottom of the bin bottom plate 4, away from the slider 3, and movable pulleys 17 are provided on both sides of the roller seat 16. The roller seat 16 is a block structure and is made of plastic or metal. The roller seat 16 is connected to the bin bottom plate 4 by bolts, and movable pulleys 17 are provided on both sides. The movable pulleys 17 have good wear resistance and shock absorption, which can make the movement of the bin bottom plate 4 more stable.

[0038] A slotted photoelectric sensor 18 is installed on the storage platform 1. A photoelectric plate 19 is installed on the side of the storage base plate 4 near the slotted photoelectric sensor 18. The slotted photoelectric sensor 18 is mounted on the storage platform 1 and fixed with bolts. The photoelectric plate 19 is a metal plate and is connected to the side of the storage base plate 4 near the slotted photoelectric sensor 18 with bolts. When the storage base plate 4 moves, the photoelectric plate 19 moves accordingly into the slotted photoelectric sensor 18, which can then identify the components on the storage base plate 4, realizing automated management of consumable information.

[0039] A handle 20 is also provided at one end of the silo bottom plate 4. The handle 20 is connected to one end of the silo bottom plate 4 by welding or bolts. When the power is off, the operator can move the silo bottom plate 4 by pulling the handle 20.

[0040] Working Principle: In this embodiment, various consumables are centrally placed on the bottom plate 4 and made movable by the drive component 12. Compared with the traditional method of dispersing and fixing consumables, this significantly shortens the pipetting path and improves extraction efficiency. Simultaneously, centralized placement reduces the space occupied by consumables, thus reducing the size of the equipment. Furthermore, the cooperation of the slot-shaped photoelectric sensor 18 and the photoelectric plate 19 enables automated management of consumable information, reducing the error rate. When consumables need to be replaced, the drive component 12 moves the bottom plate 4 to the outside of the equipment for easy replacement by the operator. After replacement, the bottom plate 4 is moved back to its original position for identification, reducing operation time and improving overall practicality and innovation.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
