Catheter usually refers to a medical device used in the medical field as a conduit that connects medical instruments to human organs. Catheters are generally made of polymer materials that are flexible and elastic to better fit the shape of human organs. Catheters play a very important role in the medical process, such as for the infusion of drugs, drainage, monitoring and so on.
In addition to the medical field, catheters are also widely used in industry, construction and other fields. For example, in factories and mines, catheters are used to transport various liquids and gases. In construction, conduits are used in the construction of indoor piping systems, playing the role of connection and diversion. Conduit not only improves the productivity in industry and construction, but also contributes to environmental protection and energy saving.
However, there are some problems with the application of conduits in some fields. For example, because catheters are prone to harboring bacteria, improper use and cleaning may lead to infections and other complications. In addition, the quality of catheters in some areas cannot be guaranteed, and there are major quality risks that may pose uncertain risks to human health. Therefore, when selecting and using catheters, attention needs to be paid to their quality and use to ensure they are safe and effective.
