Oxygen humidifier provided with novel gas diffusion device

Abstract

The invention discloses an oxygen humidifier provided with a novel gas diffusion device, which comprises a humidification bottle, wherein the humidification bottle comprises a humidification inner chamber, a gas inlet and a gas outlet; the gas inlet is connected with a gas inlet pipe; the gas inlet pipe is contained in the humidification inner chamber; the gas diffusion device is arranged at the bottom end of the gas inlet pipe, and positioned at the bottom of the humidification inner chamber; the gas diffusion device comprises a diffusion piece, a flow guide piece and a bottom cover; the flow guide piece is mounted in the diffusion piece; a cushion chamber is arranged between the diffusion piece and the flow guide piece; the bottom cover is covered at the bottoms of the diffusion piece and the flow guide piece; the flow guide piece is provided with a plurality of gas guide holes; the gas guide holes are arranged at intervals in an equidistant manner; the hole diameter of each gas guide hole is 1-5mm; and the diffusion piece is a porous sintered body. The oxygen humidifier can decompose oxygen flowing across the gas inlet into a large number of uniform minute bubbles in water, so that oxygen can be humidified sufficiently, and the humidified oxygen flow is free of water drops.

Description

technical field [0001] The invention relates to the technology in the field of oxygen humidifiers, in particular to an oxygen humidifier with a novel gas diffusion device which can fully humidify oxygen and has low noise. Background technique [0002] Patients with dyspnea such as hypoxemia require oxygen therapy. In order to avoid airway drying, the oxygen inhaled into the lungs must be fully humidified during oxygen therapy. Therefore, an oxygen humidifier is connected between the medical oxygen supply system and the oxygen supply device. The oxygen humidifier includes a humidification bottle, and the humidification bottle is provided with an air inlet and an air outlet. The trachea enters under the water surface in the humidification bottle, and then enters the oxygen supply device through the air outlet port connected with the humidification bottle for inhalation by the patient. [0003] In the prior art, oxygen enters the water directly through the intake pipe or ente...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, oxygen enters the water directly through the intake pipe or enters the water through a simple gas diffusion device, resulting in a large number of uneven bubbles, and the sound of oxygen bubbling is louder, and increases with the increase of the oxygen flow rate. Therefore, a certain amount of noise pollution is generated, especially at night, which affects sleep; at the same time, when the oxygen flow rate is high, when the oxygen inhalation flow rate is high, the oxygen flow will carry the humidification liquid water droplets into the human body, and the water droplets in the oxygen flow make the patient uncomfortable , even unwilling to accept continued oxygen therapy
