Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a droplet photocuring device. Background Technology

[0002] Microdroplets have important applications in drug controlled release, virus detection, particulate material synthesis, and catalysts. In the field of IVD (In Vitro Diagnostics), gene chips, protein chips, and dPCR all require the use of microdroplets. The development of microfluidics technology has enabled the controllable design and precise manipulation of the size, structure, morphology, and function of microdroplets, making it one of the most important technological platforms in the field of microdroplets.

[0003] Microfluidic methods for preparing microdroplets primarily utilize two immiscible liquids as the continuous and discrete phases, respectively. Droplet formation is controlled by manipulating the microtube structure and the flow rate ratio between the two phases. Driven by a pump with a fixed volumetric flow rate, the continuous and discrete phases enter different microchannels. When the two fluids meet at their intersection, the discrete phase continues to extend, forming a "plug-like" or "jet-like" liquid column, which is then clamped off by the shearing and compression of the continuous phase fluid, dispersing as microdroplets within the continuous phase.

[0004] Currently, the curing heating time and light exposure time of microdroplets are difficult to control, and the heating temperature is difficult to adjust, resulting in problems such as unstable curing process, microsphere fusion, or incomplete curing.

[0005] To address the above-mentioned problems, the present invention provides a droplet photocuring device. Summary of the Invention

[0006] To overcome the problems mentioned in the background art, the present invention adopts the following technical solution:

[0010] The light source structure is located on the upper part of the baffle and is rotatably connected to one of the baffles. When the light source structure and the baffle are closed, an illumination lamp is installed on the inner surface to provide light to the pipeline and solidify the droplets inside the pipeline. The placement length of the pipeline within the pipeline placement structure is adjustable, and the placement length of the pipeline path can be selected according to the different materials of the droplets and the different light curing times required, so as to ensure the effective solidification of the droplets.

[0017] Furthermore, the innermost ring of each of the panel sections is connected to a second straight line segment, which is parallel to the first straight line segment. The second straight line segment connects the innermost ring of the panel section to the first side of the pipeline placement structure.

[0018] Furthermore, at least one baffle is provided on the pipe placement structure at the upper part of the pipe channel, and the baffle is rotatably connected to the pipe placement structure; the above arrangement can prevent the pipe from coming out of the pipe placement structure and affecting the experimental results.

[0019] Furthermore, the baffle includes a first baffle and a second baffle. The first baffle is disposed on the upper part of a first side of the pipe placement structure, and the second baffle is disposed on the upper part of other surfaces of the pipe placement structure. The first baffle and the second baffle are fixedly connected.

[0020] Furthermore, the first baffle is a transparent plate, and the second baffle is a backlight plate; the backlight plate prevents light from scattering to the outside, reducing the solidification time of the droplets, and the transparent plate is provided to facilitate observation of the droplets.

[0021] Furthermore, the light source structure includes a top cover and an illumination lamp; the illumination lamp is fixedly connected to the bottom of the top cover, and at least one illumination lamp is provided on the top cover, the illumination lamp being a long strip lamp tube. Optionally, the illumination lamp is an ultraviolet illumination lamp.

[0022] Furthermore, the top cover and the pipeline placement structure are the same in shape and size, and the top cover and the second baffle opposite to the first baffle are rotatably connected; preferably, the top cover and the second baffle opposite to the first baffle are connected by a hinge.

[0023] Furthermore, a handle is provided on the top of the cover to facilitate operation by the operator.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example

[0036] Please refer to Figure 1-6This embodiment discloses a droplet photocuring device, comprising: a pipe placement structure 1, wherein a pipe channel is provided inside the pipe placement structure 1, the pipe channel has multiple outlets, and the pipe can be placed inside the pipe channel; a heating structure is provided inside the pipe placement structure 1 and is fixedly connected to the pipe placement structure 1; the heating structure heats and controls the temperature of the pipe; the placement length of the pipe inside the pipe placement structure 1 is adjustable; baffles are disposed at various edges on the upper surface of the pipe placement structure 1 and are connected to the pipe placement structure 1; a light source structure is disposed on the upper part of the baffles and is rotatably connected to one of the baffles; an illumination lamp 9 is disposed on the inner surface of the light source structure when the baffles are closed, for providing light to the pipe to cure the droplets inside the pipe. The placement length of the pipe inside the pipe placement structure 1 is adjustable, and the placement length of the pipe can be selected according to the different materials of the droplets and the different photocuring times required, so as to ensure the effect of droplet curing.

[0037] In some embodiments, the connection between the baffle and the pipeline placement structure 1 can be configured as a fixed connection, a detachable connection, or a movable connection.

[0038] The pipe placement structure 1 is a rectangular plate; the pipe placement structure 1 has an internal cavity, and an electric heating wire is installed inside the cavity. The electric heating wire can heat and control the temperature of the pipe placement structure 1; the electric heating wire can heat the upper part of the pipe placement structure 1 to a temperature of 35-70 degrees.

[0039] In some embodiments, the pipeline placement structure 1 is configured as an adjustable temperature heating plate, which can achieve temperature regulation; the adjustable temperature heating plate can be selected from existing technologies.

[0040] The upper surface of the pipe placement structure 1 is provided with a pipe channel, which includes a straight section and a coiled section 4. The straight section includes a first straight section 2 and a second straight section 3. The first straight section 2 is located near the width side and is parallel to the width direction of the pipe placement structure 1. The length of the first straight section 2 is half of the length of the pipe placement structure 1. The first straight section 2 is located on the second side of the pipe placement structure 1 and extends to the middle of the pipe placement structure 1. The first straight section 2 connects the second side of the pipe placement structure 1 and the coiled section.

[0041] In some embodiments, the lower half of the cross-section of the pipeline channel is semi-circular, and the upper half of the cross-section is rectangular. The length of the rectangle is the same as the diameter of the semi-circle, and the width of the rectangle is greater than the radius of the semi-circle. This arrangement ensures that the pipeline placed inside the pipeline channel will not leak out, preventing the pipeline from detaching and causing uncertainty in the length of the pipeline within the pipeline placement structure 1, which would affect the experiment. At least one baffle 5 is provided on the pipeline placement structure 1 at the upper part of the pipeline channel, and the baffle 5 is rotatably connected to the pipeline placement structure 1. This arrangement can prevent the pipeline from detaching within the pipeline placement structure 1 and affecting the experimental results. In some embodiments, the baffle 5 is fixedly connected to the pipeline placement structure 1 and spans across the pipeline channel to prevent the pipeline from detaching within the pipeline channel.

[0042] In some embodiments, the lower half of the cross-section of the pipeline channel is semi-circular, and the upper half of the cross-section of the pipeline channel is rectangular. The length of the rectangle is the same as the diameter of the semi-circle, and the width of the rectangle is greater than the radius of the semi-circle. A transparent plate is provided on the upper part of the pipeline channel, which completely covers the pipeline channel and can confine the pipeline within the pipeline channel, ensuring that the length of the pipeline within the pipeline channel is fixed and the light exposure time is fixed, which is conducive to the solidification of droplets.

[0043] In some embodiments, the cross-section of the pipeline channel is an arc shape, the pipeline extends into the first straight segment 2 and can move along the pipeline channel, and the upper width of the pipeline channel is smaller than the diameter of the pipeline channel, ensuring that the pipeline will not come out at the upper part of the pipeline channel.

[0044] The coiled section 4 is designed as a spiral coil, allowing the pipeline to enter the coiled section and fully receive light irradiation to achieve droplet solidification.

[0045] At least one coiled segment 4 is provided, and the coiled segment 4 is coiled into multiple turns. The inner circle of the first coiled segment is connected to the second coiled segment through a channel. Preferably, three coiled segments 4 are provided, so that the required light curing time varies depending on the material of the droplets in the pipeline. Thus, different lengths of pipeline channels composed of one or more coiled segments 4 can be selected.

[0046] like Figure 1 3-4 In some embodiments, the first coiled segment 4 is a counterclockwise spiral coiled segment. A channel connecting to the second coiled segment 4 is provided on the innermost circle of the coiled segment 4 to the upper right. The channel is tangent to the connection point of the first coiled segment 4, allowing the pipeline to smoothly enter the second coiled segment 4 within the channel. The second coiled segment 4 is a clockwise spiral coiled segment. A channel connecting to the third coiled segment 4 is provided on the innermost circle of the coiled segment 4 to the upper right. The channel is tangent to the connection point of the second coiled segment 4, allowing the pipeline to smoothly enter the third coiled segment 4 within the channel. The coiling direction of the third coiled segment 4 is the same as that of the second coiled segment 4.

[0047] In some embodiments, the first coiled segment 4 is a clockwise spiral coiled segment, and a channel connecting to the second coiled segment 4 is provided on the innermost circle of the coiled segment 4 towards the upper right. The channel is tangent to the connection point of the first coiled segment 4, allowing the pipe to smoothly enter the second coiled segment 4 within the channel. The second coiled segment 4 is a counterclockwise spiral coiled segment, and a channel connecting to the third coiled segment 4 is provided on the innermost circle of the coiled segment 4 towards the upper right. The channel is tangent to the connection point of the second coiled segment 4, allowing the pipe to smoothly enter the third coiled segment 4 within the channel. The coiling direction of the third coiled segment 4 is the same as that of the second coiled segment 4.

[0048] The innermost end of each panel section is connected to the second straight segment 3, which is parallel to the first straight segment 2. The second straight segment 3 connects the innermost circle of the panel section to the first side of the pipeline placement structure 1.

[0049] In some embodiments, the coiled segment 4 is configured as a wave groove, with a straight middle section and arc-shaped ends. The length of the wave groove is slightly less than the length between two opposing baffles, and the distance between the two midpoints of the wave groove is greater than the width of the wave groove itself.

[0050] The baffle includes a first baffle 6 and a second baffle 7. The first baffle 6 is disposed on the upper part of the first side of the pipe placement structure 1, and the second baffle 7 is disposed on the upper part of the other side of the pipe placement structure 1. The first baffle 6 and the second baffle 7 are fixedly connected.

[0051] The first baffle 6 is a transparent plate, and the second baffle 7 is a backlight plate; the backlight plate prevents light from scattering to the outside and reduces the solidification time of the droplets, while the transparent plate is set up to facilitate the observation of the droplets.

[0052] like Figure 1-2 5-6, The light source structure includes a top cover 8 and an irradiation lamp 9; the irradiation lamp 9 is fixedly connected to the bottom of the top cover 8, and at least one irradiation lamp 9 is provided on the top cover 8. The irradiation lamp 9 is configured as a long strip lamp tube. Optionally, the irradiation lamp 9 is an ultraviolet irradiation lamp 9; the light from the irradiation lamp 9 can be light particles or light beams. The basic principle of ultraviolet curing is to use ultraviolet light to irradiate the material, causing it to undergo a photochemical reaction, thereby achieving a rapid curing process. Under ultraviolet irradiation, the double or triple bonds in the material will break down, forming free radicals or ions. These free radicals or ions will react with surrounding molecules to form a cross-linked structure, thereby achieving the curing process.

[0053] In some embodiments, the illumination lamps 9 are set to be circular or square, and the illumination lamps 9 are evenly distributed inside the top cover 8 to ensure that the light intensity is the same at any position on the upper surface of the pipeline placement structure 1, which is beneficial to the experiment.

[0054] The top cover 8 and the pipeline placement structure 1 are the same in shape and size. The top cover 8 and the second baffle 7 opposite to the first baffle 6 are rotatably connected. Preferably, the top cover 8 and the second baffle 7 opposite to the first baffle 6 are connected by a hinge.

[0055] The top cover 8 is equipped with a handle 10, which makes it convenient for operators to open and operate the interior.

[0056] The top cover 8 is equipped with a light control switch 11, a heat control switch 12, and a heat adjustment button 13.

[0057] A temperature sensor is installed on the upper surface of the pipeline placement structure 1;

[0058] A controller 14 is installed on any side of the pipeline placement structure 1. The sensor is connected to the controller 14, and the controller 14 is connected to the illumination lamp 9. It can control the light intensity of the illumination lamp 9. The controller 14 can adjust the temperature of the heating wire and obtain the temperature information from the temperature sensor to achieve feedback regulation.

[0059] In some embodiments, the controller 14 may be replaced by a rheostat, which is used to change the temperature of the heating wire.

[0060] In some embodiments, multiple switches for the illumination lamps 9 are provided, the number of which is the same as the number of coiled sections 4. Each switch controls a portion of the illumination lamps 9 on the upper part of a coiled section 4. Depending on the material of the droplet, the required photocuring time is different. The path of the pipeline is selected through pipeline channels of different lengths composed of one or more coiled sections 4. At the same time, the corresponding switches are turned on to illuminate the corresponding coiled sections 4. The used coiled sections 4 are illuminated, while the unused coiled sections 4 are not illuminated.

[0061] The controller 14 includes a central controller 14, a data analysis module, a data storage module, and a communication module. The data analysis module, data storage module, and communication module are respectively connected to the central controller 14. The operation information is transmitted to the data analysis module for analysis, and then the analysis results are transmitted to the illumination lamp 9 and the heating wire for control through the central controller 14. The data storage module is used to effectively archive the usage records for easy retrieval and use next time.

[0062] Alternatively, in some embodiments, the interior of the pipe placement structure 1 is solid, and heating wires are arranged around the pipe placement structure 1 for heating. The interior of the pipe placement structure 1 is provided with a three-dimensional spiral channel, through which the pipe can pass. A dot-shaped irradiation lamp 9 is arranged inside the spiral channel for light irradiation to achieve the conditions for photocuring. Multiple outlets are provided at the upper part of the spiral channel, and the length of the pipe passing through the interior is marked at each outlet. The path of the pipe can be selected according to the different materials of the droplets and the different photocuring times required.

[0063] In use, depending on the material of the droplet, the required curing time varies. The path of the pipeline is selected through a pipeline channel of different lengths composed of one or more coiled sections 4. The pipeline is then inserted into the pipeline channel, passing through the first straight section 2, the coiled section 4, and the second straight section 3 in sequence, and finally extending out in the second telescopic section. The internal heating wire is turned on and adjusted to a suitable temperature. The corresponding irradiation lamp 9 is turned on, and finally the liquid is flowed into the pipeline for curing.

[0064] The above description of the embodiments is only for understanding the present invention. It should be noted that those skilled in the art can make several modifications to the present invention without departing from the principles of the invention, and these modifications will also fall within the protection scope of the claims of the present invention.
