Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a nasal oxygen supply component. Background Technology

[0002] Nasal oxygen delivery, as a method of oxygen supply, typically uses a nasal oxygen delivery device with a nasal tube and internal channels. The air source is connected to both ends of the nasal oxygen delivery device via a supply hose to provide oxygen. To avoid the supplied oxygen being too dry and damaging the patient's orifices, in the prior art, a humidifier is usually placed at the distal end of the hose. However, because the hose connecting the nasal oxygen delivery device is thinner and more flexible than the hose connecting the oxygen delivery mask, water condensed in the hose often forms water segments and is injected into the patient's orifices by fluid pressure (especially when oxygen supply is resumed after a period of inactivity), thus affecting the effectiveness of use.

[0030] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0031] like Figures 1 to 4 As shown, an embodiment of this utility model discloses a nasal oxygen supply component, which includes: a component body 10, a nasal tube 20, a humidifying component, and a water box 40.

[0032] The main body 10 of the component has a larger dimension in the lateral direction than in the front-to-back direction. A fluid channel 11 is configured inside the main body 10. The fluid channel 11 extends laterally and penetrates to the end of the main body 10, thereby forming an air inlet 12. Two oxygen supply hoses are respectively connected to the two air inlets 12. The middle region of the fluid channel 11 extends rearward to form two air outlets 13. Two nasal tubes 20 are respectively attached to the two air outlets 13. The two nasal tubes 20 are used to insert into the patient's two nostrils. In this way, the oxygen provided by the oxygen supply hoses is supplied to the patient's nose through the air outlets 13, the fluid channel 11, and the nasal tubes 20.

[0033] A roughly rectangular (or circular) accommodating cavity is configured in the middle of the main body 10, extending forward to the front side of the main body 10. The humidifying component is configured to absorb and release water. An absorbent sponge 30 is selected as the humidifying component. The absorbent sponge 30 is cut to a shape that matches the accommodating cavity and has an inner hole that can adapt to the fluid channel 11. The absorbent sponge 30 is inserted into the accommodating cavity from the front side of the main body 10. At this time, the inner hole of the absorbent sponge 30 serves as the fluid channel 11, which is connected to the fluid channel 11 of the main body 10. When the absorbent sponge 30 absorbs water, oxygen can be humidified as it passes through the fluid channel 11 within the absorbent sponge 30, thereby providing humidified oxygen to the nostrils. After placing the absorbent sponge 30 in the accommodating cavity of the main body 10, a valve 14 is fastened to the rear side of the main body 10 to encapsulate the absorbent sponge 30.

[0034] The water box 40 is detachably attached to the main body 10 of the component to continuously supply water to the humidifying component. The water box 40 includes an integrally formed crown 41 and wings 42, both of which have inner cavities. The wings 42 extend downward from the front side of the crown 41, and the inner cavity of the crown 41 communicates with the inner cavity of the wings 42. The bottom of the crown 41 has a water inlet 411, through which distilled water can be injected into the water box 40. The water box 40 is arranged on the main body 10 of the component in such a way that the crown 41 is located at the top of the main body 10, and the wings 42 are located at the front side of the main body 10. Thus, when oxygen is supplied by the oxygen supply component, the wings 42 are basically located below the crown 41, and the water in the crown 41 flows to the wings 42, supplying water to the absorbent sponge 30 through the water in the inner cavity of the wings 42. The distance between the two opposing cavity walls of the inner cavity of the wing 42 is limited to between 1 mm and 1.5 mm, and the distance between the two opposing cavity walls of the inner cavity of the crown 41 is limited to between 2 mm and 4 mm. Thus, the volume of the inner cavity of the wing 42 is significantly smaller than the volume of the inner cavity of the crown 41, so that even if there is only a small amount of water in the water tank 40, the inner cavity of the wing 42 will be filled. Preferably, two opposing slides are provided on the front side of the component body 10, and the sides of the wing 42 slide into the two slides, thereby allowing the water tank 40 to be attached to the component body 10. Furthermore, the water tank 40 can be detached by pushing the wing 42 upwards to separate it from the component body 10.

[0035] like Figure 3 and Figure 4 As shown, a slit 15 is provided on the lower inner side of the wing 42. The slit 15 extends laterally and is less than 1 mm wide. A membrane 16, which can be a biofilm 16 or a fibrous membrane 16, covers the slit 15. This membrane 16 is used to throttle the water inside the wing 42, thereby preventing water from flowing out of the slit 15 by gravity alone. A window is provided on the front side of the main body 10 opposite to the slit 15. A tongue 31 is provided on the front side of the absorbent sponge 30. The tongue 31 extends out of the window and abuts against the membrane 16 at the slit 15 of the wing 42. In this way, the absorbent sponge 30 can absorb water in the inner cavity of the wing 42 by means of its absorbent capacity, thereby maintaining a certain water storage capacity. Preferably, a sealing gasket 17 is arranged around the slit 15 to prevent water in the slit 15 area from migrating to other areas.

[0036] It should be noted that the above-mentioned nasal oxygen supply device can be used when the oxygen supply hose is not equipped with a humidifier. In this case, the water box 40 provides water to the absorbent sponge 30. In addition, the above-mentioned nasal oxygen supply device can also be used when a humidifier is installed at the far end of the oxygen supply hose. In this case, the absorbent sponge 30 absorbs the water condensed in the oxygen supply hose, thereby avoiding direct spraying onto the nostrils.
