Description

Neonate's nasal catheter oxygen tube

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to neonate's nasal catheter oxygen tube.

Background

Clinically, the air inlet end of the nasal catheter oxygen inhalation tube for adults is thick and not suitable for small nasal cavities of newborns, so that the nasal catheter oxygen inhalation tube of some newborn versions is improved, and particularly, a nasal connector extending into the nasal cavity is improved, for example, the nasal connector is made of softer materials and is smaller in size. However, even if the small nasal adapter is inserted into the nasal cavity, the small nasal adapter still touches the delicate nasal mucosa of the newborn, and under the condition of regulating the same oxygen flow, the thinner the pipeline of the nasal structure is, the faster the oxygen flow rate is, so that the inhaled oxygen can stimulate the delicate nasal mucosa of the newborn. In addition, the external-extension oxygen inhalation tube has small oxygen inhalation area, and once the extension-type nasal joint is released from the nasal cavity, the skin oxygen saturation of the infant is often reduced. In the case of premature infants, because high concentrations of oxygen tend to adversely affect the eye development of premature infants, premature intervention can lead to blindness; therefore, the principle followed by oxygen inhalation of premature infants is that the oxygen inhalation concentration can be at least selected to be high on the premise of ensuring the oxygen demand of infants. In clinic, when some premature infants stop low-flow nasal catheter oxygen inhalation, the decrease of the percutaneous oxygen saturation can occur, and even if the oxygen flow is only 0.5 liter/minute or even lower after the nasal catheter oxygen inhalation is given, the percutaneous oxygen saturation can be maintained to be stable. The improved oxygen inhalation tube is selected clinically, even if oxygen therapy needs to be given to the infant for inhalation of less than 0.5 liter/minute of oxygen, the properly positioned and stretched type transnasal oxygen inhalation tube does not cause the reduction of the oxygen saturation degree of the skin, the improved oxygen inhalation tube can also meet the oxygen demand of the infant, and the oxygen saturation degree of the skin is maintained to be stable.
