water tank for ventilator

Abstract

A ventilator water box, which is formed by sealing and cooperating an upper cover (1) and a bottom box (3), the bottom box is provided with a lower cover flange to separate the bottom box into a small chamber (3‑2) and a large chamber chamber (3-3), the upper cover (1) is provided with a cover flange, when the upper cover and the bottom box are sealed and matched, the upper cover flange and the lower cover flange are correspondingly sealed and matched, and the lower cover flange is sealed. A through hole is provided on the flange of the cover, and a silicone funnel cover (4) is fixed in the through hole through a rubber seal (5). Air inlet, the upper cover has an air outlet, the large diameter end of the silicone funnel sleeve is inserted into the interference fit between the inner annular flange and the outer annular flange, and the central hole at the small mouth end of the silicone funnel sleeve The minimum height from the lower end surface of the bottom box is greater than the height of the max line from the lower end surface of the bottom box by 10-20mm, and the above-mentioned water box structure can realize the function of 360° anti-backflow.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a ventilator water box. Background technique [0002] During the treatment process of the ventilator, the pressurized gas will continue to be blown from the fan. The patient will wear a mask for a long time to breathe, which will easily cause excessive drying and cause discomfort to the patient. If the weather turns cold, the gas delivered by the ventilator will be cold air, and it is difficult for the patient to accept the pressurized cold air, and prolonged use will easily cause the patient to catch a cold or catch a cold. Therefore, the gas delivered by the ventilator needs to be heated and humidified. In most cases, a water storage box (hereinafter referred to as the water box) is installed at the outlet of the ventilator to store a certain amount of water. The water is heated to achieve the effect of humidification and heating. [0003] The ventilator applicable in...
