[0001] The utility model relates to the technical field of medical devices, in particular to a breathing mask with an oxygen nasal fork. Background Art

[0002] In the field of medical devices, a breathing mask belongs to a patient interface, which is an interface device worn on the patient's face during ventilation treatment and is used for non-invasive ventilator assisted ventilation to improve the patient's ventilation; a nasal oxygen tube is an interface device used to connect with an oxygen supply system for human oxygen inhalation, and the catheter is inserted into the nasal cavity for oxygen inhalation. Its main function is to correct the patient's hypoxia symptoms, maintain normal blood oxygen partial pressure and blood oxygen saturation, and promote the body's metabolism. In the prior art, the breathing mask and the nasal oxygen tube are two independent devices. Generally, when using a breathing mask, the mask covers the nose and mouth, forming an integrated space, which is only used for positive pressure ventilation. At this time, the nasal oxygen tube cannot be used. Even if the nasal oxygen tube is inserted, it will cause air leakage between the breathing mask and the face. Therefore, the utility model develops a breathing mask with an oxygen nasal fork to solve the problems existing in the prior art. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a breathing mask with an oxygen nasal fork to solve the problem that in the prior art, the breathing mask and the nasal oxygen tube can only be used separately and their functions are single.

[0004] The technical solution of the utility model is: a breathing mask with an oxygen nasal fork, comprising a nasal oxygen tube component and a mask component that cooperate with each other;

[0005] The mask component includes a mouth breathing air port close to the face and a ventilation interface far from the face; a positive pressure ventilation chamber is formed inside the mask component;

[0007] Preferably, the mask component includes a cover body on the side closer to the face and a housing on the side far from the face;

The face contact part and the nose pad part are respectively configured as concave structures; the mouth breathing air port is formed on the face contact part; the oxygen nasal fork is inserted and protrudes from the nose pad part, and the oxygen supply interface is inserted on the outer contour part;

[0034] The following combines specific embodiments to further elaborate in detail on the content of the present utility model:

[0035] As Figure 1 、 Figure 2 shown, a breathing mask with an oxygen nasal fork includes a mutually cooperating nasal oxygen tube member 2 and a mask member 1, and the mask member 1 and the nasal oxygen tube member 2 are configured as an integral structure.

[0036] As Figure 1 shown, the mask member 1 includes a cover body 101 that faces the facial side during use and a housing 102 that is away from the facial side, and a positive pressure ventilation chamber is formed inside the mask member 1.

[0037] The cover body 101 is made of soft silicone and includes a face contact part 11, a pad nose part 12, and an outer contour part 13. A mouth breathing air port 14 for the patient's mouth to be accommodated is provided on the face contact part 11; an arc surface transition is adopted between the face contact part 11, the pad nose part 12, and the outer contour part 13. The face contact part 11 and the pad nose part 12 are respectively configured as concave structures. Since the cover body 101 itself is made of a soft silicone material that is easy to deform, it can be fitted to the patient's face through the deformation ability of the cover body 101 itself due to the differences in the facial shapes of different users, ensuring the sealing of the contact.

[0038] Combined with Figure 3As shown, an air vent interface 15 is provided on the housing 102. The housing 102 is snap-fitted with the cover 101. The outer contour portion 13 has a notch 18 for the outer edge of the housing 102 to be inserted and snap-fitted. The shape enclosed by the notch 18 is the same as the outer edge contour shape of the housing 102.

[0039] To achieve the assembly of the face mask component 1 and the nasal oxygen tube component 2, the nasal pad portion 12 has a first interface 16, and the outer contour portion 13 has a second interface 17. The second interface 17 is opened above the air vent interface 15.

[0040] As Figure 1 、 Figure 2 shown, the nasal oxygen tube component 2 penetrates through the face mask component 1 and includes a pair of oxygen nasal forks 21 inserted into the nasal cavity and an oxygen supply interface 22 away from the nose. Among them, the oxygen nasal forks 21 are inserted at the first interface 16, and the oxygen supply interface 22 is inserted at the second interface 17. Since the second interface 17 is opened above the air vent interface 15, the oxygen supply interface 22 is then above the air vent interface 15. In the application scenario, the pipelines connected between the two will not be disordered.

[0041] An oxygen chamber is formed inside the nasal oxygen tube component 2, and the oxygen chamber and the positive pressure ventilation chamber form relatively independent spaces. 100% concentration of oxygen is introduced into the oxygen chamber so that oxygen enters the patient's nasal cavity without dilution. The positive pressure ventilation chamber is used to provide positive pressure ventilation and does not provide additional oxygen. The two spaces are isolated to achieve the synchronous execution of positive pressure ventilation treatment and oxygen supply.

[0042] In this embodiment, the nasal oxygen tube component 2 is also made of soft silicone material. The oxygen nasal forks 21 protruding from the nasal pad portion 12 are bent and inclined toward the patient's nose direction to ensure the comfort of insertion into the nasal cavity and can also deform due to individual differences. During the assembly process of the nasal oxygen tube component 2 and the face mask component 1, the oxygen nasal forks 21 and the first interface 16 can be fixed by bonding or directly inserted. At this time, the outer diameter of the oxygen nasal forks 21 needs to be slightly larger than the inner diameter of the first interface 16, and the oxygen nasal forks 21 are pressed tightly against the first interface 16 due to their own deformation ability. Similarly, the oxygen supply interface 22 and the second interface 17 can also be fixed by bonding or directly inserted and connected.

[0043] As Figure 1 shown, air grooves 3 are also distributed on the periphery of the first interface 16 and are opened on the nasal pad portion 12 for realizing positive pressure ventilation.

[0044] In summary, in this embodiment, by integrating the face mask component 1 and the nasal oxygen tube component 2 and forming relatively independent positive pressure ventilation chamber and oxygen chamber, the former is used to achieve positive pressure ventilation, and the latter is used to supply oxygen to prevent oxygen from being diluted and directly entering the nasal cavity.

[0045] The present utility model also discloses a face mask system, as Figure 4 shown, which includes a breathing face mask with an oxygen nasal fork and a frame member 4 installed at the ventilation interface 15.

[0046] The frame member 4 includes a frame body 41 and an exhaust elbow 42 communicated with the ventilation interface 15. Connection buckles 43 are arranged at both ends of the frame body 41. In the application scenario, an elastic band can be arranged between a pair of connection buckles 43 for convenient head-mounted fixation. The exhaust elbow 42 is used to connect a ventilation hose, and a plurality of exhaust holes 44 are distributed on the exhaust elbow 42 for discharging the gas exhaled by the human body.

[0047] The above embodiments are only for illustrating the technical concept and features of the present utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it cannot be used to limit the protection scope of the present utility model. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
