Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a nasal oxygen tube with a filter. Background Art

[0002] Since the discovery of oxygen in the 1680s, a variety of oxygen therapy methods have emerged, including nasal oxygen cannulae. After more than two hundred years of development, they have been widely used. In the past decade, a new nasal oxygen therapy method called humidified high-flow nasal cannula ventilation has been discovered. It uses high-flow nasal cannulae to continuously provide patients with high-flow inhaled gas with adjustable and relatively constant oxygen concentration, temperature and humidity. It can not only protect the respiratory mucosa, but also provide longer spontaneous respiratory arrest time during anesthesia, especially for type I respiratory failure.

[0003] However, the existing devices have the following problems:

[0004] 1. Existing devices mainly fix the nasal oxygen tube directly on the outside of the patient, which makes it easy for the patient to pull the nasal oxygen tube out of the patient's nose when the patient is unconscious, affecting the patient's oxygen inhalation safety.

[0005] 2. At the same time, some devices directly transmit oxygen through the nasal oxygen tube for the patient to inhale oxygen, making it easy for the patient to inhale small particles or germs in the tube into the human body during the oxygen inhalation process, affecting the patient's health.

[0006] Therefore, in order to solve the above problems, a nasal oxygen tube with a filter is proposed. Utility Model Content

[0028] Furthermore, a fixing ring 401 is fixedly connected to the inside of the connecting shell 4, a folding tube 402 is fixedly connected above the fixing ring 401, a folding spring 403 is movably connected to the outside of the folding tube 402, and a movable ring 404 is fixedly connected above the folding tube 402, which can return the connecting tube to its original position when the patient pulls the connecting tube.

[0029] Furthermore, a surrounding pipe 502 is fixedly connected to the outside of the water tank 501, a fixed cover 503 is fixedly connected to the top of the water tank 501, a filter tube 504 is fixedly connected to the outside of the water tank 501, a fixed block 505 is fixedly connected to the inside of the filter tube 504, a filter frame 506 is fixedly connected to the inside of the fixed block 505, a filter plate 507 is fixedly connected to the inside of the filter frame 506, and a filter screen 508 is fixedly connected to the inside of the filter frame 506, which can filter impurities in oxygen.

[0030] Furthermore, a connecting strip 601 is fixedly connected to the rear of the connecting piece 6, a movable rod 602 is movably connected to the inside of the connecting strip 601, a connecting spring 603 is movably connected to the outside of the movable rod 602, and a connecting clip 604 is movably connected to the outside of the movable rod 602, which can fix the filter box.

[0031] Working principle: When using the device, first insert the connector 302 into the oxygen supply device, fix the connecting tube 2 on the patient's neck, insert the discharge tube 101 into the patient's nostrils, adjust the position of the connecting tube 2 by adjusting the clamp 201, open the fixing cover 503 by rotating it, inject water into the water storage tank 501, fix the filter box 5 on the pillar by pressing the bottom of the connecting clamp 604, and start the valve to supply oxygen to the air supply pipe 3. Oxygen is transported to the surrounding pipe 502 through the air supply pipe 3, and oxygen is discharged. The water in the water storage tank 501 raises the temperature of the oxygen, and the oxygen passes through the filter tube 504, and is filtered by the filter sheet 507 and the filter mesh 508 in the filter tube 504. The oxygen is transported to the discharge head 1 through the connecting tube 2, and then transported to the discharge pipe 101 through the discharge head 1, and then transported to the patient's nose through the discharge pipe 101. The oxygen is inhaled through the patient's breathing. When the patient pulls the connecting tube 2 unconsciously, the elastic force of the folding spring 403 pulls the movable ring 404 and the folding tube 402 to pull the connecting tube 2 into place, thereby preventing the patient from not being able to inhale oxygen.
