Abstract

The utility model relates to the technical field of medical instruments, and discloses a disposable bottle-free self-humidifying nasal oxygen tube which comprises a humidifying material, a pressing plate, a sliding rod and a sliding rod, wherein the humidifying material is arranged in a humidifying cavity, the pressing plate is connected to the inner side wall of the humidifying cavity in a sliding mode, the pressing plate is arranged on the right side of the humidifying material, one end of the sliding rod is fixedly connected to the right side wall of the pressing plate, and the other end of the sliding rod penetrates through and extends to the outside of the humidifying cavity. The sliding rod is pushed to the inside of the humidifying cavity, the clamping protrusion is pressed and deformed and slides into the clamping groove, at the moment, the sliding rod compresses the humidifying material, the pore volume of the humidifying material is reduced, free water is extruded back into the inside of the humidifying material, the surface moisture is reduced, the evaporation capacity is reduced, the oxygen humidifying degree is reduced, when the sliding rod is pulled out outwards, a fiber layer in the humidifying material stretches into a fluffy state from a compressed state, the pore volume is increased, free water stored in the inside migrates to the surface due to the action of gravity and fiber tension, the moisture attached to the fiber surface and the surface of the humidifying material is increased, the evaporation capacity is increased when the free water contacts with oxygen, and the oxygen humidifying degree is increased.

Description

Disposable bottle-free self-humidifying nasal oxygen tube Technical Field The utility model relates to the technical field of medical appliances, in particular to a disposable bottle-free self-humidifying nasal oxygen tube. Background The nasal oxygen tube is a common medical instrument, and comprises a tube body, wherein the tube body is provided with a nasal catheter communicated with the nasal oxygen tube, the nasal oxygen tube is connected with a machine end and an air source during use, oxygen is input to a patient losing self-breathing capacity through the nasal cavity by conveying the tube body, and because the humidity of the inhaled gas is strictly required by the respiratory tract of a human body, direct inhalation of dry oxygen can cause a series of physiological discomfort and even damage, so that the nasal oxygen tube is provided with a humidifying bottle, the traditional humidifying bottle needs to change water and sterilize every day, and bacteria breeding is easily caused by improper operation, so that the disposable bottle-free self-humidifying nasal oxygen tube is cleaner and sanitary. The humidification structure of the existing nasal oxygen cannula is inconvenient to adjust the humidification degree, but the demand difference of the humidification degree is larger for children, old people, patients in dry areas or people suffering from respiratory diseases. The fixed humidification degree cannot meet the personalized requirement, and may cause insufficient humidification of part of patients and excessive humidification of the other part. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides a disposable bottle-free self-humidifying nasal oxygen tube which has the advantage of being convenient for adjusting the humidifying degree, and solves the problems that the humidifying structure of the existing nasal oxygen tube is inconvenient for adjusting the humidifying degree, but different patients have different specific requirements on the humidity of oxygen, so that the humidifying structure is inconvenient for meeting different humidifying requirements.
