Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an oxygen inhalation nasal mask. Background Technology

[0002] Nasal masks, as a non-invasive ventilation method, are widely used in clinical practice due to their high comfort and ease of operation.

[0003] Currently, nasal masks on the market typically integrate a carbon dioxide collection tube to assess a patient's respiratory status in real time. The original intention of this design is to directly collect the carbon dioxide exhaled by the patient through the shared airway chamber of the nasal mask and the carbon dioxide collection tube, and then conduct continuous monitoring to assess the patient's respiratory function and status.

[0004] However, this design, where the carbon dioxide collection tube shares the airway chamber with the nasal mask, results in extremely weak or even undetectable carbon dioxide levels when used on patients with weak breathing. This makes it impossible to accurately capture the patient's faint breathing activity, thus posing a significant challenge for doctors in determining whether the patient is maintaining spontaneous breathing. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an oxygen nasal mask to solve the technical problems mentioned in the background art.

[0007] Furthermore, in the oxygen nasal mask, the central axis of the oxygen tube interface is inclined relative to the nasal mask portion.

[0008] Furthermore, in the oxygen nasal mask, the carbon dioxide collection tube is provided with a positioning ring at one end inside the nasal mask body, the outer edge of the positioning ring is attached to the inner wall of the patient's nasal cavity, and the inner edge of the positioning ring forms an air vent.

[0009] Furthermore, in the oxygen inhalation nasal mask, the outer surface of the nasal mask portion is provided with a clamp for holding and fixing the carbon dioxide collection tube.

[0010] Furthermore, in the oxygen inhalation nasal mask, the fixing clip includes a fixing plate disposed on the surface of the nasal mask portion, and a clamping plate rotatably connected to the fixing plate. The fixing plate has a magnet embedded in it, and the clamping plate has a magnetic attracting element corresponding to the magnet. The magnetic attracting element and the magnet attract each other magnetically, thereby realizing the fastening between the fixing plate and the clamping plate.

[0011] Furthermore, in the oxygen nasal mask, the side of the clamp that fits against the fixing plate is provided with a positioning groove adapted to the shape of the carbon dioxide collection tube.

[0012] Furthermore, in the oxygen nasal mask, the inner wall of the positioning groove is provided with anti-slip pads.

[0013] Furthermore, in the oxygen inhalation nasal mask, the bottom of the nasal mask portion is provided with a liquid collection tube and a sealing cap to close the liquid collection tube.

[0014] Furthermore, in the oxygen nasal mask, the side of the sealing edge that fits against the patient's skin is provided with a silicone pad.

[0015] Furthermore, in the oxygen nasal mask, the diameter of the carbon dioxide collection tube is 2-3 mm.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By inserting a carbon dioxide collection tube into the patient's nasal cavity, the carbon dioxide exhaled by the patient can be collected more directly and accurately.

[0024] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0025] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Please see Figures 1 to 4 The oxygen nasal mask of this utility model includes a nasal mask body 10, the nasal mask body 10 includes an arched nasal mask portion 11 and a sealing edge 12 provided around the nasal mask portion 11, an oxygen tube interface 20 is provided above the nasal mask portion 11, an opening is provided below the nasal mask and a carbon dioxide collection tube 30 is inserted into the opening, and one end of the carbon dioxide collection tube 30 located inside the nasal mask body 10 is connected to the patient's nasal cavity.

[0029] By inserting the carbon dioxide collection tube 30 into the patient's nasal cavity, the carbon dioxide exhaled by the patient can be collected more directly and accurately. Even if the patient's breathing is weak, trace amounts of carbon dioxide emissions can be effectively captured, improving the accuracy of monitoring the patient's respiratory status.

[0030] It should be noted that in this embodiment, the diameter of the carbon dioxide collection tube 30 is controlled between 2 and 3 mm, so that when it is inserted into the patient's nasal cavity, it will not occupy too much oxygen inhalation space, ensuring that the patient's breathing is unobstructed.

[0031] See Figure 1 The central axis of the oxygen tube interface 20 is inclined relative to the nasal mask portion 11 so that when oxygen is introduced into the nasal mask, it can flow down along the patient's nasal bridge, reducing direct impact and making it easier for the patient to inhale, thereby improving oxygen utilization efficiency.

[0032] See Figure 2 and Figure 3 The carbon dioxide collection tube 30, located within the nasal mask body 10, has a positioning ring 31 at one end. The outer edge of the positioning ring 31 fits against the inner wall of the patient's nasal cavity, and the inner edge of the positioning ring 31 forms an air vent 32. Understandably, the carbon dioxide collection tube 30, inserted into the patient's nasal cavity, is fixed by the positioning ring 31, effectively preventing the carbon dioxide collection tube 30 from dislodging from the patient's nasal cavity during breathing. The air vent 32 formed on the positioning ring 31 is used for normal oxygen inhalation. Specifically, in this embodiment, the positioning ring 31 is annular, and a fixing member connected to the carbon dioxide collection tube 30 is provided on the inner side of the positioning ring 31. The air vent 32 formed between the fixing member and the positioning ring 31 is crescent-shaped.

[0033] For further details, please refer to [link / reference]. Figure 1 and Figure 4 The outer surface of the nasal mask portion 11 is provided with a clamp for holding and fixing the carbon dioxide collection tube 30. When the patient wears the nasal mask body 10 and the carbon dioxide collection tube 30, the carbon dioxide collection tube 30 located outside the nasal mask body 10 can be fixed to the surface of the nasal mask portion 11 by the clamp, so as to prevent the carbon dioxide collection tube 30 from being pulled out of the nasal mask body 10 due to excessive movement of the patient.

[0034] Specifically, the fixing clip includes a fixing plate 41 disposed on the surface of the nose mask portion 11, and a clamping plate 42 rotatably connected to the fixing plate 41. The fixing plate 41 is embedded with a magnet, and the clamping plate 42 is provided with a magnetic attracting element corresponding to the magnet. The magnetic attracting element and the magnet attract each other magnetically, thereby realizing the fastening between the fixing plate 41 and the clamping plate 42.

[0035] Furthermore, the side of the clamping plate 42 that fits against the fixing plate 41 is provided with a positioning groove 43 adapted to the shape of the carbon dioxide collecting tube 30. The positioning groove 43 is designed to prevent the clamping plate 42 from applying excessive clamping force to the carbon dioxide collecting tube 30, which would cause the carbon dioxide collecting tube 30 to be crushed, thus ensuring the stability of the carbon dioxide collecting tube 30 in gas delivery.

[0036] Furthermore, the inner wall of the positioning groove 43 is provided with anti-slip stickers, which are used to increase the friction between the clamping plate 42 and the carbon dioxide collecting tube 30, so as to further improve the fixing effect of the carbon dioxide collecting tube 30 and prevent the carbon dioxide collecting tube 30 from loosening.

[0037] See Figure 1 The bottom of the nasal mask portion 11 is provided with a collection tube 51 and a sealing cap 52 to seal the collection tube 51. The collection tube 51, in conjunction with the sealing cap 52, is used to collect nasal mucus or nasal crusts flowing from the patient's nasal cavity, facilitating cleaning. Specifically, in this embodiment, the collection tube 51 is rectangular in shape, and its central axis is aligned with the central axis of the oxygen tube interface 20, thus aligning with the patient's nasal cavity and enabling effective collection of nasal mucus.

[0038] See Figure 2 The sealing edge 12 has a silicone pad 60 on the side that fits against the patient's skin, which can improve the comfort and airtightness of the patient when wearing the nasal mask body 10.

[0039] See Figure 1 The nasal mask body 10 is provided with hooks 70 on both sides. The hooks 70 are used to connect and fix the straps, and the nasal mask body 10 is worn on the patient's nose through the fixing straps.

[0040] In summary, the oxygen nasal mask in the above embodiments of this utility model can collect carbon dioxide exhaled by the patient more directly and accurately by inserting the carbon dioxide collection tube 30 into the patient's nasal cavity. Even if the patient's breathing is weak, it can effectively capture trace amounts of carbon dioxide emissions, thereby improving the accuracy of monitoring the patient's respiratory status.
