Description

Technical Field

[0001] The utility model relates to the technical field of ventilators, in particular to a ventilator tube anti-condensation water heating device. Background Art

[0002] The ventilator tube is the gas passage between the ventilator and the connecting device such as the artificial airway or mask. It ensures that the ventilator delivers air into the lungs and the air is discharged from the lungs to the body. It is generally a threaded tube made of low-compliance materials. There are two basic types: single-circuit and double-circuit. When the patient uses the ventilator, the oxygen in the inlet pipe is humidified by the humidifier and heated by the electric heating wire before being inhaled by the patient. The air exhaled by the patient is discharged from the outlet pipe. Because the temperature of the air exhaled by the patient is close to the body temperature and contains moisture, during the discharge process along the outlet pipe, the indoor temperature is usually controlled at around 25 degrees. At this time, a large amount of condensed water will easily appear in the outlet pipe. Since the ventilator tube is generally made of low-compliance materials, it is easy to bend during use. The gas exhaled by the patient is blocked by the bent ventilator tube, which makes it easier to produce condensed water.

[0003] In view of this, we propose a ventilator tube anti-condensation water heating device. Utility Model Content
