Abstract
Description
Technical Field
[0001] The utility model relates to the field of sedimentation and bubble filtration of infusion sets, in particular to a sedimentation and bubble filtration mechanism for a shaking infusion set. Background Art
[0002] During the infusion process, because the drip rate is relatively slow, drug precipitation will occur, and bubbles may also be generated. There are similar infusion devices on the market that can filter precipitation, but they are equipped with a filter net, such as Figure 1 As shown, however, this filter is stationary, and the precipitates will gather on the surface of the filter, which will easily affect the passage of the liquid, reduce the dripping rate, and the effect of breaking and removing bubbles is not very good. Therefore, how to avoid the accumulation of precipitates on the filter when filtering drugs is an urgent problem that technicians in this field need to solve. Utility Model Content
[0003] The utility model aims to provide a sedimentation and bubble filtering mechanism for a shaking infusion set to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sedimentation and bubble filtering mechanism for a shaking infusion set, comprising a filter screen located in a vertical tube body, a floating component capable of removing sedimentation and bubbles when shaken to generate buoyancy is provided at the lower end of the filter screen, and at the same time, the power generated when the liquid drips is utilized to achieve sedimentation filtering and bubble removal through liquid surface shaking, and the floating component is hollow to facilitate liquid leakage, mainly to facilitate liquid downward flow.
[0005] Preferably, the floating assembly is annular in shape. The annular support has better stability and is not prone to tipping over.
[0006] Preferably, the floating component is a ring-shaped airbag, which has good buoyancy, is not easily worn and does not produce impurities, and ensures that the liquid is clean and hygienic.
[0007] Preferably, a horizontal shaking gap is left between the periphery of the airbag and the circumferential inner wall of the tube body to achieve horizontal shaking.
[0008] Preferably, the cross section of the airbag is triangular, and the outer end surface is a vertical anti-rollover portion, and the vertical height of the anti-rollover portion is greater than the width of the shaking gap. In this way, when tilted, the anti-rollover portion will abut against the inner wall of the tube body, thereby preventing rollover.
[0009] Preferably, the airbag is made of latex, which is more hygienic.
[0010] Preferably, the tube body is a Moffitt dropper, which utilizes the original structure of the infusion set and also ensures verticality, thereby reducing production costs.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. The filter screen filters the sediment and bubbles. The suspended airbag drives the filter screen to shake, thereby shaking the sediment and bubbles, dissolving the sediment and bursting the bubbles.
[0013] 2. The tube body adopts the Maupi dropper, so the filter part can be directly installed without changing the structure of the original infusion set, which is simple and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 2 to 4 The utility model provides a technical solution for a sedimentation and bubble filtering mechanism for a shaking infusion set: a sedimentation and bubble filtering mechanism for a shaking infusion set, comprising a filter screen 2 located in a vertical tube body 1, the tube body 1 being a Maupe dropper, utilizing the original structure of the infusion set, while also ensuring verticality, thereby reducing production costs. A floating component capable of removing sedimentation and bubbles when shaking is provided at the lower end of the filter screen 2, generating buoyancy, and at the same time utilizing the power generated when the liquid drips, through the shaking of the liquid surface, filtering of sedimentation and removal of bubbles are achieved, and the floating component is hollow to facilitate the liquid to leak downward, mainly to facilitate the liquid to flow downward.

The airbag 3 has good buoyancy and is not easy to wear and produce impurities, ensuring that the liquid is clean and hygienic. A horizontal shaking gap is left around the airbag 3 and the circumferential inner wall of the tube body 1. Horizontal shaking is achieved. The cross-section of the airbag 3 is triangular, and the outer end face is a vertical anti-rollover part 4, and the vertical height of the anti-rollover part 4 is greater than the width of the shaking gap. In this way, the anti-rollover part 4 will press against the inner wall of the tube body 1 when tilted, so that it cannot roll over. The material of the airbag 3 is latex material, which is more hygienic.
[0022] Working principle: The filter 2 filters the sediment and bubbles, and the suspended air bag 3 drives the filter 2 to shake, thereby shaking the sediment and bubbles, dissolving the sediment and bursting the bubbles. The tube body 1 adopts the Moffitt dropper, and the filter part can be directly installed without changing the structure of the original infusion set, which is simple and practical.
