Description

Neonate does not have breathing machine pipeline heat preservation device of wound

Technical Field

The utility model relates to a breathing machine pipeline heat preservation device technical field, concretely relates to neonate does not have breathing machine pipeline heat preservation device of wound.

Background

In modern clinical medicine, a ventilator has been widely used in treatments such as respiratory failure due to various causes, anesthesia and breathing management during major surgery, respiratory support treatment, and emergency resuscitation as a device capable of manually replacing the function of spontaneous ventilation. The respiratory machine can prevent and treat respiratory failure and reduce complications, and is vital to saving and prolonging the life of a patient.

The respirator is provided with a humidifier for humidifying inhaled air instead of nasal cavities and oral cavities, and the heated and humidified air is conveyed to a patient through a respirator pipeline. The temperature and the humidity of the heated and humidified gas are higher, the pipeline of the breathing machine is usually longer, and the heated and humidified gas can generate condensed water when passing through the pipeline of the breathing machine with the lower temperature. Condensed water may be collected at the joint of the pipeline to affect the ventilation effect and may flow back to the mouth of a patient, so that the patient is uncomfortable to use the machine; and after the condensed water is separated out from the gas, the gas humidity is reduced, and the comfort of the patient is poorer after the patient is used for a long time.
