Description

Nasal oxygen supply part Technical Field The utility model relates to the technical field of medical equipment, in particular to a nasal oxygen supply part. Background Nasal ventilation is commonly used as a ventilation means by using a nasal ventilation member having a nasal tube and an internal passage, and a gas source is connected to both ends of the nasal ventilation member through a gas supply hose for supplying oxygen, in order to prevent the supplied oxygen from being excessively dry to damage a wall hole of a patient, a humidifier is usually disposed at a distal end of the hose in the prior art, however, since the hose connecting the nasal ventilation member is relatively thin with respect to the softness of the ventilation mask, water condensed in the hose often forms a water segment to be supplied into the wall hole of the patient in a jet manner by fluid pressure (especially when ventilation is again performed after ventilation is stopped for a certain period of time), thereby affecting the use effect. Disclosure of utility model In view of the above-mentioned technical problems in the prior art, embodiments of the present utility model provide a nasal oxygen supplying device. In order to solve the technical problems, the technical scheme adopted by the embodiment of the utility model is as follows: a nasal oxygen delivery device, comprising: A component main body, wherein a fluid channel is arranged in the component main body, the fluid channel transversely extends to two ends of the component main body to form an air inlet interface for connecting with oxygen supply cartilage, and the middle part of the fluid channel extends towards the rear side to form two air outlet interfaces; a nasal tube comprising two, two nasal tubes attached to the outlet port, the nasal tubes for insertion into nostrils; A humidifying member disposed inside the member body, through which the fluid passage penetrates so that oxygen can pass through the humidifying member, the humidifying member being capable of adsorbing water, and humidifying oxygen as the oxygen passes through the humidifying member; A water cartridge attached to the component body for providing water to the humidifying component. Preferably, the humidifying member is made of a water absorbing sponge. Preferably, the front side of the component body is provided with a detachable shutter through which the humidifying component is implanted in the component body. Preferably, the water box comprises a crown and wings which are integrally formed and each have an inner cavity, the wings extending downward from the front side of the crown, the inner cavities of the crown communicating with the inner cavities of the wings, wherein: The crown is disposed at the top of the component body so that the wing is located at the front side of the component body, and the component body supplies water to the humidifying component through the wing. Preferably, a gap penetrating through the inner cavity is formed in the inner side of the wing part, a window is formed in the front side of the part main body, a tongue is arranged in a region corresponding to the window of the humidifying part, and the tongue penetrates through the window and abuts against the gap. Preferably, the slit is covered with a membrane, and the tongue abuts against the membrane.
