Description

Technical Field

[0001] The utility model relates to the technical field of in vitro diagnostic microsphere dispensing devices, and particularly relates to an in vitro diagnostic microsphere dispensing device. Background Technique

[0002] With the rapid development of various polymer microsphere synthesis technologies, microspheres with different shapes and particle sizes are widely used in the fields of pharmaceutical medicine, interventional medicine, materials science, chromatography separation, etc. At present, there are mainly various methods for microspheres such as emulsion polymerization, precipitation polymerization, and suspension polymerization.

[0003] Currently, when dispensing microspheres, due to the relatively wide range of particle sizes prepared for microspheres, when using traditional dispensing devices to dispense microspheres with different particle sizes, different filter plates need to be used to intercept other particle size microspheres with particle sizes different from the required ones, resulting in the need to install different filter plates multiple times, which is time-consuming and laborious. To solve this problem, in the prior art, for example, the Chinese patent with the publication number of CN220536154U discloses a microsphere dispensing device. When dispensing microspheres, the microspheres are sent into the dispensing cylinder inside the shell and filtered through the corresponding filtering surface. The microspheres that meet the particle size are collected and dispensed through the corresponding filtering surface, while the microspheres that do not meet the corresponding filtering surface are intercepted and need to be manually taken out. Moreover, multiple filtering surfaces are integrated on the dispensing cylinder. When dispensing microspheres with different particle sizes, the dispensing cylinder can be rotated according to the actual use situation, so that one of the filtering surfaces on the dispensing cylinder rotates to the bottom to complete the filtering and dispensing of the corresponding particle size microspheres. However, when using this device, it is necessary to manually take out the defective products with particle sizes that do not meet the requirements. In order to reduce human errors, improve production efficiency, reduce labor costs, speed up the work process, and make the work process more efficient and accurate, in view of this, an in vitro diagnostic microsphere dispensing device is proposed.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Please refer to Figures 1 - 4, the present utility model provides an in vitro diagnostic microsphere dispensing device, which includes a housing 2 fixedly installed on the upper side of a bracket 1. A feed hopper 21 is arranged on the upper side of the housing 2, and filter holes 23 are formed on the surface of the housing 2. When the microspheres are conveyed inside the housing 2, the microspheres smaller than the size of the filter holes 23 will be screened out through these holes to achieve screening. A discharge hopper 22 is fixedly installed on the lower side of the housing 2. The microspheres with qualified sizes are conveyed to the discharge hopper 22 and discharged under the action of a conveying component 4, and finally fall into a storage box 6. A motor 3 is arranged on one side of the housing 2 to convey and screen the materials inside the housing 2. A blanking plate 24 is fixedly installed on the other side of the housing 2 to guide the microspheres that have not been screened out through the filter holes 23 into a recovery box 7. In this way, the unqualified microspheres are effectively separated and collected. A storage box 6 is arranged on the lower side of the discharge hopper 22, and the storage box 6 collects the qualified microspheres that have been screened out through the filter holes 23. The blanking plate 24 is provided with a recovery box 7 on the side far from the housing 2, and a precision microsphere pump 71 is arranged on the outer wall of the recovery box 7, and the precision microsphere pump 71 is communicated with the recovery box 7. The precision microsphere pump 71 is communicated with a microsphere conveying pipeline 72, and the microsphere conveying pipeline 72 is communicated with the feed hopper 21. Through re-screening, the possibility of errors or omissions can be further reduced to ensure the accuracy of the screening results. Especially when dealing with a large number of microspheres, re-screening further ensures the accuracy of the screening results. A conveying component 4 is arranged inside the housing 2. The conveying component 4 includes a rotating shaft 41, and one end of the rotating shaft 41 is fixedly connected to the output end of the motor 3. The other end of the rotating shaft 41 penetrates the housing 2. A spiral blade 42 is arranged on the outer wall of the rotating shaft 41, and a cam 43 is fixedly installed on the outer wall of the rotating shaft 41, and the rotating shaft 41 penetrates the cam 43.

[0026] Furthermore, a knocking mechanism 5 is arranged on the outer wall of the housing 2. The knocking mechanism 5 includes a support block 51 fixedly installed on the outer wall of the housing 2. A knocking rod 52 is hinged on the inner wall of the support block 51. A hammer head 54 is fixedly connected to one side of the knocking rod 52. The design of the hammer head 54 should have a certain mass and hardness to ensure that it can generate sufficient knocking force on the housing 2 without damaging the housing 2. One end of a tension spring 53 is fixedly installed on the outer wall of the support block 51, and the other end of the tension spring 53 is fixedly installed on the knocking rod 52. The number of the knocking mechanisms 5 is two groups, and the two knocking mechanisms 5 are symmetrically arranged on both sides of the housing 2 with the midline of the housing 2 as the axis of symmetry. When the motor 3 drives the rotating shaft 41 to rotate, the cam 43 will also rotate accordingly. At a specific position of the cam 43, it will come into contact with the knocking rod 52, push the knocking rod 52 to rotate around the hinge point, so that the hammer head 54 knocks on the housing 2. As the cam 43 continues to rotate, the knocking rod 52 resets under the action of the tension spring 53 and waits for the next knock. By means of physical vibration, it helps the microspheres to maintain smoothness during the conveying and screening processes, prevents blockage, and may improve the screening efficiency.

[0027] It should be noted that the above electrical components are all existing technology products. Those skilled in the art select, install and complete the circuit debugging operations according to the needs of use to ensure that all electrical appliances can work properly. The components are all general standard parts or parts known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods. The applicant does not make specific restrictions here.

[0028] In the present utility model, when in use, after the motor 3 starts, its output end drives the rotating shaft 41 to rotate. Driven by the motor 3 to rotate, the rotating shaft 41 passing through the housing 2 drives the spiral blade 42 to rotate. When the spiral blade 42 rotates, it pushes the microspheres forward. Under the push of the conveying assembly 4, the microspheres move forward inside the housing 2 and pass through the filtering holes 23. The microspheres meeting the size requirements pass through the filtering holes 23 and then enter the storage box 6 through the discharge funnel 22, while the microspheres not meeting the requirements continue to move forward to the blanking plate 24 and slide down along the inclined surface of the blanking plate 24 into the recycling box 7. The microspheres entering the recycling box 7 are pumped out by the precision microsphere pump 71. The pumped-out microspheres enter the microsphere conveying pipeline 72 through the precision microsphere pump 71. The microspheres continue to flow along the microsphere conveying pipeline 72 and finally return to the inlet of the feeding funnel 21. When the motor 3 drives the rotating shaft 41 to rotate, the cam 43 will also rotate accordingly. At a specific position of the cam 43, it will come into contact with the knocking rod 52 and push the knocking rod 52 to rotate around the hinge point, so that the hammer head 54 knocks on the housing 2. As the cam 43 continues to rotate, the knocking rod 52 is reset under the action of the tension spring 53 and waits for the next knock. The vibration generated by the knock helps to prevent the microspheres from being blocked at the filtering holes 23 and improves the screening efficiency.

[0029] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
