Abstract

The invention discloses a manual wet air and oxygen mixing system and belongs to the technical field of medical equipment. The manual wet air and oxygen mixing system comprises an air path, an oxygenpath and a mixing output path, wherein the air path comprises an air inlet, an air filter device, a manual air flow valve and an air flow detection device which communicate sequentially; the oxygen path comprises an oxygen inlet, an oxygen filter device, a manual oxygen flow valve and an oxygen flow detection device which communicate sequentially; the end, far from the air inlet, of the air path and the end, far from the oxygen inlet, of the oxygen path respectively communicate with a gas mixing device; the air inlet communicates with the air outlet of an air supply device; and the oxygen inlet communicates with an oxygen storage device. The manual wet air and oxygen mixing device has mass flow, good stability, high repeatability, simple adjustment and low cost.

Description

technical field [0001] The invention relates to a manual humidification air-oxygen mixing system, which belongs to the technical field of medical equipment. Background technique [0002] There are two types of traditional oxygen inhalation devices, one is pure oxygen circuit output, and most of these devices are disposable oxygen inhalation devices. Oxygen inhalation is carried out through nasal cannula, and pure oxygen reaches the patient's nose through nasal cannula. In the process, pure oxygen is inhaled together with the surrounding air to achieve the effect of oxygen inhalation. The oxygen concentration inhaled by the patient with the oxygen inhalation device output by the pure oxygen circuit is not constant, and the oxygen concentration inhaled by different patients is not constant. Uncertain, at the same time, the humidification bottle is simply oxygen passing through water, and the humidification effect is extremely limited. When the patient inhales oxygen for a peri...
