Novel medical oxygen humidifying device and humidifying method

Abstract

The invention relates to a novel medical oxygen humidifying device and a humidifying method, and belongs to the technical field of medical oxygen humidifying of medical institutions and families. According to the technical scheme, a spiral propelling device (7) is composed of blades (11) fixed to the periphery of a center shaft sleeve (19), the center shaft sleeve is provided with internal threads (12), external threads (20) of a screw (10) are matched with the internal threads of the spiral propelling device (7), the spiral propelling device is located in an upper space air chamber (9), and the center shaft sleeve of the spiral propelling device is tightly attached to the outer surface of an upper pressing plate (5). Air flow entering the upper space air chamber from an upper hollow air inlet pipe (3) pushes the spiral propelling device (7) to rotate, and the spiral propelling device pushes the upper pressing plate to move. According to the novel medical oxygen humidifying device and the humidifying method, a liquid-water-free gas humidifying structure is adopted, the requirement for the position and the inclination angle of a barrel is avoided, the humidifying degree in the barrel is not changed when the barrel is located at different positions, and the use requirements of various environments, positions and angles are met.

Description

technical field [0001] The invention relates to a novel medical oxygen humidification device and a humidification method, belonging to the technical field of medical oxygen humidification for medical institutions and households. Background technique [0002] Oxygen inhalation is a commonly used clinical treatment method. The most commonly used method for oxygen inhalation therapy is nasal cannula oxygen inhalation. Medical oxygen must be humidified before it can be used on patients. The traditional humidifier needs to replace the humidification water every day, which is easy to be polluted during use. When improperly operated or in a mobile environment, it is easy to produce humidification fluid splashing, causing harm to patients. At the same time, during the humidification process , will generate loud noise, which is not conducive to the treatment of patients.

Problems solved by technology

The traditional humidifier needs to replace the humidification water every day, which is easy to be polluted during use. When improperly operated or in a mobile environment, it is easy to produce humidification fluid splashing, causing harm to patients. At the same time, during the humidification process , will generate loud noise, which is not conducive to patient treatment

Chinese utility model patent CN206414582U uses a solid-state humidification ball to replace the traditional humidification liquid, which solves some problems, but there are still the following problems: as the humidification time increases, the humidification ball gradually shrinks, and the humidification The gap between the ball and the humidification bottle increases, the number of humidification balls participating in the humidification decreases, the degree of humidification decreases rapidly with the increase of the humidification time, and the effective humidification time is shortened

The applicant’s utility model patent 2020224591038 solves a certain problem. The spring is used to control the number of solid humidification balls involved in humidification, which ensures the degree of humidification to a certain extent, but it will cause the following adverse consequences: 1. The selection of springs is difficult, The spring has the maximum elasticity in the initial state, and it has been in the state of maximum elasticity during storage and transportation. If the elasticity is too large, the solid humidification ball will be broken; even if the spring is suitable, the solid humidification ball will also be caused by external pressure. Risk of humidification fluid penetrating the surface causing liquid water inside the humidification bottle

2. During the humidification process, the volume of the solid-state humidification ball shrinks continuously, the downward stroke of the spring continues to increase, the elastic force of the spring gradually decreases, and the effect of the upper platen on restricting the solid-state humidification ball decreases synchronously, which will affect the humidity of the humidifier. degree

2. The upper pressing plate does not slide in one direction; the spring has two actions of contraction and expansion. In the case of vibration, the upper pressing plate will slide up and down in the cylinder. In extreme cases, such as when the acceleration changes greatly, the upper pressing plate will It will also slide up and down; the pressure of the upper platen on the solid humidification ball will also change during the sliding process, which will affect the degree of humidity and safety
