Abstract: A nutritional infusion tubing assembly includes a peristaltic tube, an input tube connector, an output tube connector, infusion tubes, and a support plate. The support plate is provided with a guide channel that guides the movement of the support plate. The input tube connector is connected to the peristaltic tube and an infusion tube, and the output tube connector connects the peristaltic tube to another infusion tube. A section of the peristaltic tube close to the input end and a section of the peristaltic tube close to the output end are subjected to an outward expansion force from the support plate, the input tube connector, or the independent expansion member. The internal structures of the nutritional infusion tubing assembly can provide expansion force sufficient to enable one-handed nutritional tubing installation. Additionally, due to the guiding effect of the guide channel, the installation process is highly reliable.

Abstract: A nutritional infusion system includes an infusion device and a nutritional infusion tubing assembly. The nutritional infusion tubing assembly includes infusion tubing, which in turn includes a peristaltic tube. The nutritional infusion device includes a housing, a power supply, a control assembly, a driving component, a roller, and a first fixing member. The housing has a mounting panel, and the mounting panel has a guide rail. The guide rail guides movement and placement of the nutritional infusion tubing assembly, which is provided with a guide channel. The cooperation between the guide channel and the guide rail reduces interference from elastic resistance generated by stretching the peristaltic tube during installation. This allows the nutritional infusion tubing to be smoothly installed, even with only one hand, on the nutritional infusion device by applying only a force along the extension direction of the guide rail.

Abstract: An enhanced coagulation method for removing microplastics in water is provided. First, a certain amount of inorganic suspended particles are added to microplastic wastewater to increase the number of particles and thereby improve a collision probability among the particles; and then a natural polymer flocculant and a polysilicic acid are added.

The enhanced coagulation method can combine respective characteristics and advantages of the three materials, so that the three materials can mutually complement each other and give full play to the role of charge neutralization and bridging and net capturing, strengthen the sedimentation performance and enhance the actual microplastic removal effect. Therefore, it is a green and environmentally-friendly enhanced coagulation technology.

The scale inhibitor is prepared by grafting reaction with hydroxyethyl cellulose as a raw material, ammonium persulfate as an initiator and N-(3-dimethylaminopropyl) methyl acrylamide as a graft monomer. The grafting reaction can introduce grafting chains containing amide group and tertiary amine group into a cellulose molecular chain, so that it can effectively disperse scale forming substances and obtain the efficient environment-friendly scale inhibitor. The scale inhibitor can effectively inhibit the generation of silica scale and prevent the increase of scale particle size, the scale inhibitor is used in a reverse osmosis system, which can effectively alleviate the decline of the membrane flux. The scale inhibitor has a good application prospect in controlling the silica scale on the surface of the reverse osmosis membrane.
