Description

Thermal insulation pipe with surface covered with film Technical Field The application relates to the technical field of medical instruments, in particular to a heat preservation pipe with a surface film. Background In the medical field, oxygen therapy is one of the most commonly used therapeutic means in clinic, and is a treatment for hypoxia caused by various reasons. The oxygen dissolution in the plasma is improved by sucking high-concentration oxygen, so that the oxygen supply of tissues is improved, and the metabolism is promoted. Common oxygen therapy methods include nasal obstruction and nasal oxygen inhalation, mask inhalation, transcatheter oxygen therapy, electronic pulse oxygen therapy, mechanical ventilation and oxygen administration, and high pressure oxygen therapy. The nasal oxygen cannula and the mask are used as a member of medical equipment in the oxygen therapy method, and play a great role in medical scenes such as emergency rooms, operating rooms, general ward, ICU intensive care units and the like. The nasal oxygen tube is used for relieving the hypoxia symptom of patients in some acute respiratory distress, maintaining vital sign balance, and patients with chronic respiratory diseases such as asthma can also obtain necessary oxygen supply support through the nasal oxygen tube and the mask, and nursing before and after an operation, so that the patients can be helped to quickly recover the physical health state, and various postoperative complications can be reduced. Meanwhile, when the altitude stress enters the altitude region and possibly causes altitude stress symptoms, timely oxygen supplement can be provided, so that the influence of altitude stress on people is reduced. Therefore, in order to meet the actual demands, the heat-insulating pipe with the surface coated with the film is provided.
