Description

Technical Field

[0001] This utility model relates to the field of biomedical experimental technology, specifically to a multi-channel diversion device based on the principle of turbulence and its matching unloading plate. Background Technology

[0002] In daily life and biomedical experiments, rapid and accurate quantitative dispensing of gases and liquids is a routine operation. In daily life, the requirements for dispensing accuracy are relatively low. However, in the field of biomedical experiments, due to the complexity of the experimental process and the need to ensure the stability and repeatability of experimental results, there are extremely high requirements for the rapid and accurate addition of fluids (especially reagents). Precise addition operations directly affect the reliability of experimental data and the validity of experimental conclusions. Currently, common devices for quantitative fluid dispensing on the market include single-channel and multi-channel pipettes, and these devices generally achieve rapid and accurate sampling and dispensing of liquid reagents through a plunger mechanism. However, the plunger structure, the core component of existing pipettes, is quite complex and requires high machining precision, resulting in relatively high manufacturing costs and hindering large-scale application. Furthermore, during frequent experimental operations, the plunger structure, as a core component, is prone to wear, which directly leads to a decrease in dispensing accuracy, resulting in significant dispensing errors and affecting the accuracy of experimental results. Moreover, to avoid dispensing errors and ensure dispensing accuracy, pipettes (especially multi-channel pipettes) require regular professional calibration and maintenance, which not only increases maintenance costs but also affects the continuity of experimental work. In addition, after the experiment, the pipette tips or silicone tubes on the multi-channel pipette need to be manually disassembled one by one, which is cumbersome and affects experimental efficiency.

The device includes a multi-channel flow splitting body, a pressure regulating plunger, and an unloading plate body. The multi-channel flow splitting body is integrally formed by a fixed ring platform, a flow splitting shell, and several outflow pipes. The flow splitting shell is provided with a connecting part consisting of a large-size groove and a small-size inflow hole. The flow splitting shell is provided with a flow splitting cavity communicating with the inner side of the small-size inflow hole. The diversion cavity includes an upper cavity communicating with the inner side of the small-sized inflow hole, two middle cavities communicating with the upper cavity through a first through hole, and two lower cavities communicating with the two middle cavities one-to-one through a second through hole. The two middle cavities and the two lower cavities are symmetrically arranged with the small-sized inflow hole as the axis of symmetry. The two lower cavities are respectively connected to several outflow pipes through a third through hole. The inner walls of the two lower cavities are respectively provided with multiple pressure regulating holes for inserting pressure regulating plungers. Each pressure regulating hole is located at the connection between two adjacent outflow pipes, and the first through hole and the third through hole are respectively offset from the second through hole. The unloading plate body has several unloading through holes, each of which corresponds to a number of outflow pipes. The unloading plate body is fitted onto the outer wall of the outflow pipes of the multi-channel diversion body through the several unloading through holes.

[0005] Preferably, the unloading plate body is a column with a gantry-shaped longitudinal section, and a cavity is opened at the bottom of the column. Several unloading through holes are connected to a cavity, and two symmetrically arranged fixing buckles are provided at the bottom of the column.

[0006] Preferably, the column is an elliptical cylinder, and a plurality of the unloading through holes are equidistantly arranged along the major axis of the top surface of the column.

[0007] Preferably, the diameter of the large-size groove gradually decreases from the groove opening towards the inside of the groove, and the inner wall of the large-size groove opening is provided with a first groove and a second groove for placing the sealing ring.

[0008] Preferably, the small-sized inflow hole is located inside the large-sized groove, the large-sized groove and the small-sized inflow hole are coaxially arranged, and the diameter of the small-sized inflow hole gradually decreases from the opening of the large-sized groove towards the inside of the groove.

[0009] Preferably, the outer wall of the small-sized inflow hole is provided with a first annular protrusion group distributed from top to bottom along the axial direction of the small-sized inflow hole.

[0010] Preferably, the outer walls of several outflow pipes are provided with second annular protrusion groups distributed along the axis of the outflow pipe, and the outer walls of the outflow pipes are provided with a sleeve section located above the second annular protrusion groups.

[0011] Preferably, the outer wall of the pressure regulating plunger is provided with a first sealing ring.

[0013] Preferably, the bottom of the fixed ring platform is provided with a first fixed arm and a second fixed arm, and the fixed ring platform is integrally formed with the diversion shell through the first fixed arm and the second fixed arm.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: In this invention, by setting an upper cavity, a middle cavity, and a lower cavity in the multi-channel diversion body, the fluid can be diverted layer by layer in the upper cavity, the middle cavity, and the lower cavity. Furthermore, due to the staggered design of the first through hole, the second through hole, and the third through hole, multi-stage turbulence is generated, which greatly balances and compensates the pressure and fluid velocity of each outlet pipe, thereby achieving relatively uniform pressure and fluid velocity in the eight outlet pipes.

[0015] In this invention, when the pressure and fluid velocity of each outlet pipe are uneven, the operator can adjust the depth of the pressure regulating plunger to regulate the pressure and fluid velocity of different outlet pipes, thereby achieving uniform pressure and fluid velocity in each outlet pipe. Furthermore, the pressure regulating plunger has a simple structure. Compared to existing plunger components with complex overall structures, the pressure regulating plunger in this solution can be mass-produced through injection molding or machining, significantly reducing manufacturing costs and facilitating large-scale application. Simultaneously, compared to existing diversion devices that rely on complex plunger structures, this solution eliminates plunger structures that are prone to wear due to frequent use, avoiding errors caused by wear and improving the accuracy of experimental results. Routine maintenance only requires periodic inspection and replacement of the first sealing ring on the pressure regulating plunger, reducing maintenance frequency and costs, and extending the service life of the device.

[0016] In this invention, when installing the suction head or silicone tube, the unloading plate body is first fitted onto the outflow tube. After the experiment, multiple suction heads or silicone tubes can be unloaded at the same time simply by pushing the matching unloading plate body. The operation is simple, convenient, time-saving, and labor-saving. Attached Figure Description

[0024] It should be noted that when a component is referred to as being "assembled on," "mounted on," "fixed to," or "set on" another component, it can be directly on the other component or there may be an intermediate component.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] like Figures 1-4As shown, this utility model provides a multi-channel diversion device and a matching unloading plate based on the principle of turbulence. It includes a multi-channel diversion body 100, a pressure regulating plunger 200 and an unloading plate body 300. The multi-channel diversion body 100 is integrally formed by a fixed ring platform 101, a diversion shell 102 and several outflow pipes 103. The diversion shell 102 is provided with a connecting part composed of a large-size groove 1021 and a small-size inflow hole 1022. Among them, the most common multi-channel split devices on the market are single-channel, 8-channel, 12-channel, 96-channel and 384-channel split devices, such as multi-channel pipettes and multi-channel pipetting workstations. This solution mainly uses the most common 8-channel multi-channel split device as an example. Therefore, the multi-channel split body 100 in this solution has 8 outflow tubes 103. Before using the multi-channel split device, the multi-channel split body 100 needs to be connected to existing negative pressure equipment (such as vacuum pumps, syringes, single-channel pipettes) through the connection part to realize the multi-channel suction and injection functions. Therefore, the connection part on the split housing 102 is designed with a large-size groove 1021 and a small-size inflow hole 1022 to facilitate connection.

[0027] Furthermore, the diameter of the large-size groove 1021 gradually decreases from the opening towards the inside of the groove, and the inner wall of the opening of the large-size groove 1021 is provided with a first groove 110 and a second groove 120 for placing the sealing ring. Through the design of the first groove 110 and the second groove 120, both can be adapted to commercially available O-rings of various sizes, and during adaptation, it can be ensured that the O-ring completely fits the groove wall without twisting or deformation; thus, the sealing performance can be increased when the connection is connected to the negative pressure equipment.

[0028] Furthermore, the small-diameter inflow hole 1022 is located inside the large-diameter groove 1021. The large-diameter groove 1021 and the small-diameter inflow hole 1022 are coaxially arranged, and the diameter of the small-diameter inflow hole 1022 gradually decreases from the opening of the large-diameter groove 1021 towards the inside of the groove. The outer wall of the small-diameter inflow hole 1022 is provided with a first annular protrusion group 130 distributed from top to bottom along the axial direction of the small-diameter inflow hole 1022. Through the design of the first annular protrusion group 130, it is easy for the multi-channel diversion body 100 to avoid slippage due to pressure when connected to commercially available syringes or silicone tubes, thus ensuring the stability and sealing of the connection with the negative pressure device.

[0029] In summary, the inner walls of both the large-size groove 1021 and the small-size inflow hole 1022 are designed with bevels. Together with the sealing O-rings in the first annular protrusion group 130, the first groove 110, and the second groove 120, they ensure a tight fit between the connection of the multi-channel diversion body 100 and the negative pressure equipment, enhance connection stability, ensure no loosening and no risk of air or liquid leakage, and also avoid errors caused by fluid leakage.

[0030] Furthermore, the bottom of the fixed ring platform 101 is provided with a first fixed arm 170 and a second fixed arm 180, and the fixed ring platform 101 is integrally formed with the diversion housing 102 through the first fixed arm 170 and the second fixed arm 180. The design of the first fixed arm 170 and the second fixed arm 180 can assist in stabilizing the multi-channel diversion body 100 and the negative pressure equipment, and prevent the multi-channel diversion device from shifting during operation.

[0031] Combination Figure 2 and Figure 3 As shown, further, the diversion housing 102 is provided with a diversion cavity communicating with the inner side of the small-sized inflow hole 1022. The diversion cavity includes an upper cavity 1023 communicating with the inner side of the small-sized inflow hole 1022, two middle cavities 1024 communicating with the upper cavity 1023 through a first through hole 104, and two lower cavities 1025 communicating with the two middle cavities 1024 one-to-one through a second through hole 105. The two middle cavities 1024 and the two lower cavities 1025 are symmetrically arranged with the small-sized inflow hole 1022 as the axis of symmetry. The two lower cavities 1025 are respectively connected to a plurality of outflow pipes 103 through a third through hole 106. The first through hole 104 and the third through hole 106 are respectively offset from the second through hole 105.

[0032] Specifically, the upper cavity 1023, the middle cavity 1024, and the lower cavity 1025 are used to form a connected inner cavity to achieve layer-by-layer flow distribution. The upper cavity 1023 has six first through holes 104 at its inner bottom. The six first through holes 104 are arranged in groups of three. The two groups of first through holes 104 are symmetrically arranged with the small-sized inflow hole 1022 as the axis of symmetry. Each group of first through holes 104 corresponds to the outer side of the eight outflow pipes 103 arranged in a straight line. The inner bottom of each middle cavity 1024 has three second through holes 105, and the three second through holes 105 are staggered with the three first through holes 104 on the same side. The inner bottom of each lower cavity 1025 has four third through holes 106. The two lower cavities 1025 are connected to the eight outflow pipes 103 through the eight third through holes 106. Therefore, during the flow of fluid from the upper cavity 1023, the middle cavity 1024, and the lower cavity 1025, the staggered design of the first through-hole 104, the second through-hole 105, and the third through-hole 106 generates multi-stage turbulence. This turbulence generates additional pressure locally. Furthermore, since the three cavities are interconnected, the turbulence can greatly balance and compensate for the pressure and fluid velocity in each outlet pipe 103, thus achieving relatively uniform pressure and fluid velocity in all eight outlet pipes 103. In this way, through the flow distribution of fluids (such as reagents and gas streams) based on the principle of turbulent structure in a multi-channel interconnected cavity, precise and stable distribution of fluids is possible.

[0033] As a further step, the outer walls of several outflow pipes 103 are respectively provided with second annular protrusion groups 140 distributed along the axial direction of the outflow pipe 103, and the outer walls of the outflow pipes 103 are provided with a sleeve section located above the second annular protrusion groups 140. The outer walls of the outflow pipes 103 are provided with third annular grooves 160 for placing sealing rings.

[0034] Specifically, in order to ensure that the multi-channel diversion body 100 is not contaminated or damaged, disposable commercial pipette tips or silicone tubes will be fitted onto different outflow tubes 103 in some experimental scenarios. Then, by setting a second annular protrusion group 140 and a third groove 160 on the outer wall of the outflow tube 103, it is easy to install a commercial sealing ring in the third groove 160. Thus, when the outflow tube 103 is connected to the commercial pipette tip or silicone tube, the second annular protrusion group 140 prevents the pipette tip or silicone tube from slipping due to pressure, ensuring the stability and sealing of the connection between the pipette tip or silicone tube and the outflow tube 103.

[0035] As a further step, the inner walls of the two lower cavities 1025 are respectively provided with a plurality of pressure regulating holes 107 for inserting the pressure regulating plunger 200. Each pressure regulating hole 107 is located at the connection between two adjacent outflow pipes 103. There are six pressure regulating holes 107 and six pressure regulating plungers 200 respectively. The six pressure regulating holes 107 are not only located at the connection between two adjacent outflow pipes 103, but also located below each second through hole 105. This allows the depth adjustment of the pressure regulating plunger 200 to adjust the pressure and fluid flow rate of the outflow pipe 103 at the corresponding position, thereby achieving uniform pressure and fluid flow rate in each outflow pipe 103.

[0036] Furthermore, the outer wall of the pressure regulating plunger 200 is provided with a first sealing ring 150. The design of the first sealing ring 150 prevents the pressure regulating plunger 200 from easily slipping out due to pressure after being inserted into the pressure regulating hole 107. Moreover, the pressure regulating plunger 200 proposed in this solution has a simple structure. Compared to existing plunger components with complex overall structures, the pressure regulating plunger 200 of this solution can be mass-produced through injection molding or machining processes, significantly reducing manufacturing costs and facilitating large-scale application. Simultaneously, compared to existing diversion equipment that relies on complex plunger structures, this solution eliminates plunger structures that are prone to wear due to frequent use. Routine maintenance only requires periodic inspection and replacement of the first sealing ring 150, reducing maintenance frequency and costs, and extending the service life of the device.

[0037] like Figure 1 and Figure 2As shown, the unloading plate body 300 has several unloading through holes 301, each of which corresponds to a number of outflow pipes 103. The unloading plate body 300 is fitted onto the outer wall of the outflow pipes 103 of the multi-channel diversion body 100 through the several unloading through holes 301. The unloading plate body 300 is a column 302 with a gantry-shaped longitudinal section. A cavity 303 is opened at the bottom of the column 302. Each of the several unloading through holes 301 communicates with a cavity 303. The bottom of the column 302 is provided with two symmetrically arranged fixing buckles 304. The column 302 is an elliptical cylinder, and the several unloading through holes 301 are equidistantly arranged along the long axis of the top surface of the column 302.

[0038] When the unloading plate body 300 is fitted onto the outflow tube 103, the second annular protrusion group 140 on the outflow tube 103 can be located within the cavity 303, while the unloading through hole 301 is fixedly positioned on the smooth wall of the outflow tube 103 (i.e., above the first through hole 104) due to the fitted arrangement. This allows the operator to install commercially available suction tips or silicone tubes onto the corresponding outflow tubes 103. After the experiment, the operator only needs to push the matching unloading plate body 300 to unload multiple suction tips or silicone tubes at once, making the operation simple and convenient. It is worth noting that this solution mainly uses the most common 8-channel multi-channel diversion device as an example. If other multi-channel diversion devices are used, the unloading through holes 301 on the matching unloading plate will correspond to multiple outflow tubes 103.

[0039] Working principle and usage process of this utility model: First, connect the multi-channel diverter body 100 to an existing external negative pressure device via the connecting part. Then, insert the pressure regulating plunger 200 into the corresponding pressure regulating hole 107 and adjust it to a consistent depth. Next, attach the matching unloading plate body 300 onto the outflow pipe 103 of the multi-channel diverter body 100. Finally, connect the commercially available suction tip or silicone tube to the corresponding outflow pipe 103. During this process, all locations requiring sealing O-rings are placed during assembly to ensure the device's airtightness after assembly.

[0040] When the multi-channel diversion body 100 is in use, after the fluid enters from the connection part, it can be diverted layer by layer in the upper cavity 1023, the middle cavity 1024 and the lower cavity 1025. During the diversion process, the staggered design of the first through hole 104, the second through hole 105 and the third through hole 106 will generate multi-level turbulence, which greatly balances and compensates the pressure and fluid velocity of each outlet pipe 103, thereby achieving relatively uniform pressure and fluid velocity of the eight outlet pipes 103. During this period, when the pressure and fluid velocity of each outlet pipe 103 are not uniform, the operator can adjust the depth of the pressure regulating plunger 200 to adjust the pressure and fluid velocity of different outlet pipes 103, so as to make the pressure and fluid velocity of each outlet pipe 103 uniform.

[0041] After the experiment is completed, the operator only needs to push the matching unloading plate body 300 to unload multiple suction heads or silicone tubes at the same time, which is simple and convenient.

[0042] In summary, this utility model, through the diversion of multiple interconnected cavities based on the principle of turbulent structure, can accurately and stably distribute the fluid, thereby achieving uniform pressure and fluid velocity in each outlet pipe 103.
