Oxygen humidifying and conveying device

Abstract

The invention discloses an oxygen humidifying and conveying device. The device comprises a closed container, a humidifying unit of the closed container, an oxygen input port and an oxygen output port, wherein the closed container is formed by connecting an upper shell and a lower shell; the middle of the closed container is provided with a central pipe from the top to the bottom; a partition board is arranged in the closed container between the oxygen input port and the oxygen output port; a plurality of radial oxygen baffle plates are arranged in the closed container at equal angles by using the central pipe as a center; each oxygen baffle plate is provided with a vent port and the vent ports on adjacent two oxygen baffle plates are formed in an internal and external partition mode; the humidifying unit is a humidifying unit of a synthetic macromolecular water absorption material after absorbing water or a mixture of a synthetic macromolecular material and liquid water; and the humidifying unit contains antibacterial agent and preservative. The oxygen conveying device has the advantages of no noise, bacteria resistance, no iatrogenic infection, good oxygen humidifying effect and simple structure.

Description

Problems solved by technology

[0002] In order to solve the problem that medical oxygen does not contain water, so that patients generally feel that the respiratory tract is dry after inhaling oxygen, a variety of oxygen humidification oxygen delivery devices have appeared in recent years, and oxygen humidification bottles are often used to humidify oxygen. Through the tube into the liquid surface of the humidification bottle, a large number of oxygen bubbles will emerge from the water surface and enter the terminal delivery pipe. The disadvantage of an oxygen humidification oxygen delivery device with this structure is the generation of bubbles and noise; with the development of medical and related science With the continuous development of the continuous development, oxygen inhalation of humidified oxygen cylinders is widely used in clinical medicine. Due to the different types of diseases of patients who inhale oxygen, the etiology and the types of pathogenic microorganisms infected are also different. If oxygen humidification cylinders are used in rotation among patients, it is easy to Cross-infection; in addition, the cavity of the oxygen humidification bottle is prone to breed bacteria, which further increases the problem of cross-infection

In summary, the existing oxygen humidification bottle has the following disadvantages: 1. The traditional oxygen "water humidification" method further promotes the occurrence of nosocomial infection

2. Studies have shown that: on the premise that the existing oxygen humidification and oxygen delivery device is not disposable, distilled water or saline is used as the humidification fluid, and the humidification fluid should not be replaced once every 8 hours at the longest. Reduce the probability of contamination of humidification fluid, but also significantly increase the burden of nursing work

3. Oxygen passes through the ventilation tube to produce water bubbles that make loud noises, which often affect the patient's sleep, and the greater the oxygen flow rate, the more obvious the noise
