[0030] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0031] With reference to Figures 2 to 4 , the utility model provides an embodiment: a clinical oxygen nasal clip for breathing, including oxygen tube 1, oxygen tube 1 is used to pass into oxygen, provides the gas support necessary for the maintenance of life for patient. The middle part of oxygen tube 1 is fixedly connected with two nasal tubes 2, and the position and angle of the nasal tube 2 are consistent with the human body state. The nasal tube 2 is used to transport oxygen into the patient's nasal cavity, so as to ensure that oxygen can be smoothly delivered to the starting part of the respiratory system. A plurality of air outlets 3 are formed in the outer portion of the nasal tube 2, and the air outlet 3 is used for the gas exhaust of the patient. The top of the nasal tube 2 is fixedly connected with the fixing ring 4, and the fixing ring 4 is used to fix the whole nasal clip in the patient's nasal cavity, so as to prevent the nasal clip from falling due to the patient's tremor and other factors. The inner wall of the fixing ring 4 is fixedly connected with a connecting assembly for connecting subsequent mechanisms.

[0032] The connecting assembly comprises a connecting ring 5 for supporting the whole connecting mechanism, the inner wall of the connecting ring 5 is fixedly connected with a plurality of connecting columns 6, the connecting columns 6 are designed to have a certain area of cavity between the plurality of connecting columns 6, so that the gas can pass through smoothly. The proximal end of the plurality of connecting columns 6 is fixedly connected with a top disc 7, which provides a stable fixed mounting point for the subsequent mechanism. The bottom of the top disc 7 is fixedly connected with a fixed column 8, which is used to connect the subsequent mechanism. The other end of the connecting assembly is fixedly connected with a piston 9, the bottom of the fixed column 8 is fixedly connected to the top of the piston 9, the piston 9 is used to block the oxygen channel when the patient exhales, so as to prevent the mixing of oxygen and patient exhaled gas, so as to reduce the oxygen concentration of the gas inhaled by the patient again, and then affect the oxygen supply effect.

[0033] The inner wall of the nasal tube 2 is slidingly connected with a foam light ring 10, which is a key component for separating patient oxygen inhalation and exhalation. The movement of the foam light ring 10 allows the exhaled gas to be discharged from the air outlet hole 3, while the oxygen can enter the patient's nasal cavity completely during inhalation. At the same time, the foam light ring 10 is made of foam material, so that the patient's breathing can easily drive the foam light ring 10 to move, thereby avoiding increasing the respiratory burden of the patient. The diameter of the piston 9 is the same as the inner diameter of the foam light ring 10, so that the piston 9 forms a sealing mechanism during the movement of the foam light ring 10, thereby preventing the mixing of oxygen during patient exhalation, resulting in a decrease in oxygen supply effect. The inner wall of the nasal tube 2 is provided with a movable groove 12, which provides a sliding path for the sliding of the foam light ring 10. The outer wall of the foam light ring 10 is slidingly connected inside the movable groove 12, so that the foam light ring 10 moves axially along the movable groove 12, preventing gas leakage caused by the deviation of the foam light ring 10. The upper and lower ends of the foam light ring 10 are respectively fixedly connected with two sealing rings 11, which are made of air-tight rubber material and are used to prevent oxygen from directly passing through the air outlet hole 3 through the gap between the foam light ring 10 and the movable groove 12. The outer walls of the two sealing rings 11 are slidingly connected inside the movable groove 12, so that the sealing rings 11 can seal the movable groove 12. The outer wall of the fixed ring 4 is fixedly connected with a fixing assembly for fixing the nose clip to the patient's nasal cavity.

[0034] Referring to Figures 1 to 3The fixing assembly comprises a plurality of springs 14, which have good elasticity and fatigue resistance, and the whole fixing assembly can completely fit the inner wall of the patient's nasal cavity through the elastic deformation of the springs 14, so as to prevent the nasal clip from falling off due to shaking and other factors. The proximal ends of the plurality of springs 14 are fixedly connected to the outer wall of the fixing ring 4, so that the springs 14 can be mounted on the fixing ring 4. The other ends of the plurality of springs 14 are fixedly connected with a stop plate 15, the shape of the stop plate 15 conforms to the shape of the inside of the human nasal cavity, and the stop plate 15 can move through the deformation of the springs 14, so that the stop plate 15 can fit the inner wall of the patient's nasal cavity. A plurality of mounting grooves 13 are formed in the outer part of the fixing ring 4, and the proximal ends of the plurality of springs 14 are fixedly connected to the inner part of the mounting grooves 13, so that the mounting grooves 13 provide mounting support points and deformation support points for the springs 14.

[0035] Working principle: in use, the springs 14 are compressed by pressing the stop plate 15, and then the top of the nasal tube 2 is inserted into the patient's nasal cavity, and then the stop plate 15 is released, so that the springs 14 restore the deformation and drive the stop plate 15 to move outward and fit the inner wall of the patient's nasal cavity, so as to fix the whole nasal clip in the patient's nasal cavity and prevent loosening.

[0036] When the patient inhales, oxygen enters the nasal tube 2 through the oxygen pipe 1 and moves upward through the action of air pressure, until the foam light ring 10 moves to the top of the piston 9, so that oxygen can flow through the fixing ring 4 into the patient's nasal cavity through the foam light ring 10; when the patient exhales, the foam light ring 10 moves downward due to the action of gravity and the air pressure of the exhaled gas, so that the air outlet 3 is exposed, and at the same time the piston 9 enters the inner wall of the foam light ring 10 to form a blocking structure, so that the oxygen transportation stops, and the exhaled gas is discharged from the air outlet 3, so as to prevent the mixture of oxygen and residual exhaled gas during secondary breathing and reduce the oxygen supply effect.

[0037] Finally, it should be pointed out that the above-mentioned is only the preferred embodiment of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
