Description

Technical Field

[0001] The utility model relates to the technical field of nasal masks, in particular to a novel nasal mask. Background Art

[0002] A nasal mask is a medical device worn on the patient's mouth and nose to assist the patient's breathing or perform nebulization treatment. During nebulization treatment, the nasal mask can effectively improve the absorption rate and treatment effect of the drug, and is particularly suitable for patients with some chronic respiratory diseases.

[0003] The above-mentioned and existing technologies have the following defects: when using a nasal mask, a plastic hose is used to connect the nasal mask to the nebulizer or oxygen supply equipment. Since the plastic hose is usually a round tube structure with smooth inside and outside, when the plastic hose is squeezed, the plastic hose is easily deformed and affects the flow of gas along the plastic hose, thereby affecting the normal operation of the nasal mask.

[0004] Therefore, a new nasal mask is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the defect that when the plastic hose is squeezed, the plastic hose is easily deformed, which affects the flow of gas along the plastic hose, thereby affecting the normal operation of the nose mask, and proposes a new type of nose mask.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a new type of nasal mask, comprising a nasal mask body, the surface of the nasal mask body is rotatably connected to a curved tube, one end of the curved tube is detachably installed with a bellows, one end of the bellows is fixedly connected to a fixed tube, the inner wall of the fixed tube is rotatably connected to a double rotary joint, the arc surface of the double rotary joint is rotatably connected to a connecting tube, the inner wall of the connecting tube is rotatably connected to an adapter tube, the surface of the nasal mask body is detachably installed with an elastic band, and the arc surface of the bellows is fixedly connected to a fixing buckle.

[0007] The effect achieved by the above components is: by setting the bellows, when using the nasal mask body, the bellows with a corrugated structure has good pressure resistance and bendability, which can effectively avoid the situation where the air cannot flow along the bellows due to squeezing. At the same time, when the bellows is bent, it can also keep the interior unobstructed.

[0008] Preferably, a clamp is fixedly connected to the surface of the double rotary joint.

[0009] The effect achieved by the above components is that by clamping the clip on the patient's clothes, the position of the double rotary joint can be restricted, thereby preventing the connection between the fixed tube and the double rotary joint from loosening.

[0010] Preferably, a plurality of protrusions are fixedly connected to the surface of the clip.

[0011] The effect achieved by the above components is that the protrusion can improve the clamping stability of the clip.

[0012] Preferably, a silicone ring is fixedly connected to the surface of the nasal mask.

[0013] The effect achieved by the above components is that the silicone ring can improve the sealing between the nasal mask body and the patient's face.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] In the utility model, by setting a bellows, when the nasal mask body is used, the bellows with a corrugated structure has good pressure resistance and bendability, which can effectively avoid the situation where the air cannot flow along the bellows due to squeezing. At the same time, when the bellows is bent, it can also keep the interior unobstructed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, the utility model provides a new type of nasal mask, including a nasal mask body 1, the surface of the nasal mask body 1 is rotatably connected to a curved tube 2, one end of the curved tube 2 is detachably installed with a bellows 3, one end of the bellows 3 is fixedly connected to a fixed tube 4, the inner wall of the fixed tube 4 is rotatably connected to a double rotary joint 5, the arc surface of the double rotary joint 5 is rotatably connected to a connecting tube 6, the inner wall of the connecting tube 6 is rotatably connected to an adaptor tube 7, an elastic band 8 is detachably installed on the surface of the nasal mask body 1, a fixing buckle 9 is fixedly connected to the arc surface of the bellows 3, a clip 10 is fixedly connected to the surface of the double rotary joint 5, and the clip 10 is clamped on the patient's clothes to limit the position of the double rotary joint 5, thereby preventing the loose connection between the fixed tube 4 and the double rotary joint 5, a plurality of protrusions 12 are fixedly connected to the surface of the clip 10, and the protrusions 12 can improve the clamping stability of the clip 10, and a silicone ring 11 is fixedly connected to the surface of the nasal mask, which can improve the sealing between the nasal mask body 1 and the patient's face.

[0024] Its overall working principle is that when using the nasal mask body 1, putting the elastic band 8 on the patient's head can limit the position of the nasal mask body 1, and the silicone ring 11 can improve the sealing between the nasal mask body 1 and the patient's face. At the same time, clamping the clip 10 on the patient's clothes can limit the position of the double rotary joint 5, thereby preventing the fixed tube 4 and the double rotary joint 5 from loosening. The protrusion 12 can improve the clamping firmness of the clip 10, and then connect it to the nebulizer or oxygen supply equipment with the help of the adapter tube 7. After that, the nasal mask body 1 can be used to assist the patient's breathing or treatment. In this process, the bellows 3 with a corrugated structure has good pressure resistance and bending properties, which can effectively avoid the situation where air cannot flow along the bellows 3 due to extrusion. At the same time, when the bellows 3 is bent, it can also keep the inside unobstructed.
