Description

Technical Field

[0001] This application relates to the field of dispensing device technology, and more specifically, to a multi-channel reagent dispensing device. Background Technology

[0002] Reagent dispensing is a crucial step in daily research and production across many fields, including chemistry, biology, and medicine. Traditional reagent dispensing methods largely rely on manual operation, such as using pipettes or pipettes to draw a certain amount of reagent from a reagent bottle and then injecting it into the target container. While this method meets basic dispensing needs to some extent, its inherent drawbacks have become increasingly apparent. First, manual dispensing is extremely inefficient, especially when large quantities of reagents need to be dispensed. Researchers are required to perform repetitive operations for extended periods, consuming significant time and energy. The monotonous repetitive nature of these operations can also lead to fatigue, increasing dispensing errors. Second, during manual dispensing, repeated contact with both the reagent bottle and the target container makes it difficult to completely avoid the risk of cross-contamination.

[0003] With the advancement of technology, some automated reagent dispensing equipment has emerged on the market. Through preset programs and precise mechanical structures, these equipment can greatly improve the efficiency and accuracy of dispensing. However, these devices often have problems such as complex structure and high cost. For laboratories with limited budgets or small experimental scales, purchasing and maintaining these devices is a considerable expense.

[0004] Therefore, we propose a multi-channel reagent dispensing device to address the existing problems. Utility Model Content

A dispensing hole 31 is provided on the bottom wall of the liquid storage chamber 35. A first adapter 32 corresponding to the dispensing hole 31 is provided on the bottom of the housing 3. A detachable adapter plate 5 and a fixing plate 6 are sequentially connected to the bottom of the housing 3. A second adapter 52 is fixedly installed on the adapter plate 5. A reagent tube 7 is fixed on the fixing plate 6. The top end of the second adapter 52 is connected to the first adapter 32, and the bottom end of the second adapter 52 is connected to the reagent tube 7 to form a dispensing channel 33. One end of the dispensing channel 33 is connected to the housing 3 through the dispensing hole 31, and the other end is connected to the reagent tube 7.

[0028] Furthermore, there are several dispensing holes 31, which are arranged in a matrix on the bottom wall of the storage chamber 35 and are connected to several first adapters 32 one by one. The outer wall of the first adapter 32 connected to the second adapter 52 is provided with a first sealing ring 34. In use, multiple dispensing holes 31 are distributed in a matrix on the bottom wall of the storage chamber 35, and each dispensing hole 31 corresponds to a first adapter 32. Reagents can be dispensed from multiple channels at the same time, which improves work efficiency. The first sealing ring 34 on the first adapter 32 ensures the sealing between the first adapter 32 and the second adapter 52 and prevents reagent leakage.

[0029] Furthermore, the adapter plate 5 is provided with a number of stepped holes 51, and a second adapter 52 is snapped into the stepped holes 51. One bottom end of the second adapter 52 passes through the stepped holes 51 and is connected to the reagent tube 7. A third sealing ring 53 is provided on the outer wall of the bottom end of the second adapter 52 to ensure the sealing between the second adapter 52 and the reagent tube 7 during use.

[0030] Furthermore, the fixing plate 6 is provided with several fixing grooves 61 for installing reagent tubes 7. The positions of the fixing grooves 61 correspond one-to-one with the positions of the dispensing holes 31 and the dispensing stepped holes 51 and are coaxial. In use, each reagent tube 7 can be accurately connected to the corresponding dispensing channel 33 to ensure that the reagent can be accurately dispensed into each reagent tube 7.

[0031] Furthermore, the bottom of the housing 3 is also provided with a guide assembly 4. The guide assembly 4 has multiple sets, and the multiple sets of guide assemblies 4 are respectively arranged around the outer ends of several first adapters 32. The guide assembly 4 includes a guide rod 42 fixedly connected to the bottom of the housing 3. A spring 41 is fitted on the guide rod 42. In use, it ensures that the adapter plate 5 and the fixing plate 6 can accurately align with the bottom of the housing 3 during installation and maintain a stable connection. The connection depth between the first adapter 32 and the second adapter 52 can be finely adjusted by compressing the spring 41 to ensure the stability and sealing of the connection.

[0032] Furthermore, the adapter plate 5 and the fixing plate 6 are respectively provided with a first guide hole 54 and a second guide hole 62 at corresponding positions, which allow the guide rod 42 to move through. During use, it is ensured that the adapter plate 5 and the fixing plate 6 can move and adjust along the direction of the guide rod 42 during installation, so as to achieve an accurate docking position.

[0033] Furthermore, a top cover 2 is provided at the top of the box body 3, and a second sealing ring 36 is provided between the connection end of the box body 3 and the top cover 2 to seal the box body 3 and prevent the reagent from being contaminated during the dispensing process.

[0034] Furthermore, a connecting flange 22 and a vent pipe 21 are provided above the top cover 2. The connecting flange 22 has a channel along the axis that connects to the liquid storage chamber 35. One end of the vent pipe 21 passes through the top cover 2 and connects to the liquid storage chamber 35, while the other end away from the top cover 2 is connected to a pressurizing device 1. In use, the connecting flange 22 and the vent pipe 21 are provided above the top cover 2. The connecting flange 22 has a channel that connects to the liquid storage chamber 35, which is used to deliver reagent liquid to the liquid storage chamber 35 of the box 3. The other end of the vent pipe 21 is connected to the pressurizing device 1. When it is necessary to dispense reagents, the pressurizing device 1 can pressurize the liquid storage chamber 35, forcing the reagent to enter the reagent tube 7 through the dispensing hole 31 and the dispensing channel 33. Pressurized dispensing can gradually increase the pressure in the liquid storage chamber 35, making it easier to control the reagent to be dispensed into the reagent tube 7 in equal amounts and simultaneously through the matrix-distributed dispensing holes 31.

[0035] In use, the box body 3 has a hollow liquid storage chamber 35 inside for storing reagents to be dispensed. The bottom wall of the liquid storage chamber 35 has multiple dispensing holes 31 for distributing the reagents from the liquid storage chamber 35 into various dispensing channels. The bottom of the box body 3 has a first adapter 32 corresponding to each dispensing hole 31. Below the bottom of the box body 3, a detachable adapter plate 5 and a fixing plate 6 are connected in sequence. A second adapter 52 is fixedly installed on the adapter plate 5, and multiple reagent tubes 7 are fixed on the fixing plate 6. The top of the second adapter 52 is connected to the first adapter 52. The head 32 is connected to the bottom and the reagent tube 7 is connected to the first adapter 32 and the dispensing hole 31 in sequence through the corresponding second adapter 52, forming an independent dispensing channel. When dispensing begins, the liquid storage chamber 35 is pressurized by the pressurizing device 1, and the reagent in the liquid storage chamber 35 will flow into each dispensing channel through the dispensing hole 31, and then flow into the corresponding reagent tube 7 along the dispensing channel. Since each dispensing channel is independent, multiple reagent tubes 7 can be dispensed at the same time, which greatly improves the work efficiency.

[0036] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
