Description

Technical Field

[0001] The utility model relates to the technical field of oxygen absorption tubes, in particular to an anti-falling structure for high-flow oxygen absorption tubes. Background Art

[0002] Oxygen tubes are commonly used to deliver oxygen to people who need additional oxygen support. They are widely used in the medical field, especially in emergency, hospital and nursing environments, to deliver oxygen from oxygen cylinders or oxygen generators to the patient's nose to provide additional oxygen and ensure that the patient can breathe in enough oxygen.

[0003] The oxygen tube device usually consists of a soft tube connected to an oxygen source, and then delivers oxygen to the patient's nose or mouth through a nasal cannula. The flow of oxygen increases the oxygen content in the patient's respiratory tract and helps the patient take in more oxygen.

[0004] Due to the differences in nostril size and distance between patients of different ages, long-term use may easily cause the oxygen tube to fall off, which may lead to interruption of oxygen delivery and affect the patient's oxygen supply. Especially for patients who require continuous oxygen support, the falling off of the oxygen tube may lead to reduced treatment effectiveness and even cause health risks. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-4 The utility model provides an embodiment: an oxygen inhalation component, including an oxygen supply tube 1 for supplying oxygen, a diverter 2 for adjusting the oxygen supply amount, a diverter hose 5 for conveying oxygen, and a nasal tube 14 inserted into the nostrils, an anti-falling component, including an adjusting tube 12, an ear hanging tube 6 is arranged on the outer wall of the diverter hose 5, a fixing belt 7 is fixedly connected to the outer wall of the ear hanging tube 6, a Velcro 8 is arranged on the end of the fixing belt 7 away from the ear hanging tube 6, the end of the diverter hose 5 away from the diverter 2 is fixedly connected to the limiting tube 4, the limiting tube 4 is slidably connected to the adjusting tube 12, and the inner wall of the limiting tube 4 away from the end of the diverter hose 5 is fixedly connected with a connecting tube 15, the nasal tube 14 is arranged on the outer wall of the adjusting tube 12 on the side away from the limiting tube 4, the outer wall of the nasal tube 14 is detachably connected with a nasal plug 3, the outer wall of the adjusting tube 12 is provided with a limiting component, and the limiting component includes a spring 9.

[0031] By setting an ear hook tube 6 on the outer wall of the diverter hose 5, the outer part of the ear hook tube 6 is made of soft and comfortable material, and the inner part is made of harder material to prevent the diverter hose 5 from collapsing during wearing. The ear hook tube 6 can be easily hung behind the ear, providing better comfort and stability.

[0032] The top of the adjusting tube 12 is fixedly connected to the spring piece 9, and the outer wall of the spring piece 9 is symmetrically fixedly connected with a pressing rod 11, and the outer wall of the pressing rod 11 is fixedly connected with a connecting rod 13, and the connecting rod 10 is fixedly connected with an arc-shaped limiting rod 10 at one end away from the pressing rod 13. The shape of the outer wall of the arc-shaped limiting rod 10 is consistent with the shape of the outer wall of the limiting tube 4, and an anti-sliding block 16 is provided on the outer wall of the arc-shaped limiting rod 10 close to the limiting tube 4. The outer wall shape of the nasal plug 3 is a double-layer cone, and the outer wall shape of the spring piece 9 is U-shaped. The limiting tube 4, the adjusting tube 12 and the connecting tube 15 are interconnected and the outer walls are tightly fitted, and the inner wall of the adjusting tube 12 away from the limiting tube 4 is slidably connected to the connecting tube 15.

[0033] The fixing belt 7 is made of a soft material with a certain tensile force, which can be fixed on the head to help fix the oxygen tube in the correct position, and the Velcro 8 can be used to adjust the length of the fixing belt 7 to ensure that the tightness and comfort of the oxygen tube can be optimally balanced.

[0034] The spring piece 9 is in a U-shape. When the spring piece 9 is separated to both sides, the two ends of the U-shape will naturally come together to form a tighter clamp. The anti-sliding block 16 can increase the friction between the arc-shaped limiting rod 10 and the limiting tube 4, thereby improving the stability of the device.

[0035] Working principle: In order to make the oxygen inhalation tube conform to the nostril size and spacing of different people, the U-shaped spring piece 9 can be deformed by pressing the pressing rod 11, and then the arc-shaped limit rod 10 is driven away from the limit tube 4 through the connecting rod 13, thereby releasing the limit on the adjustment tube 12, so that the adjustment tube 12 can slide on the limit rod 4 to adjust the distance between the nasal tubes 14. Subsequently, the pressing rod 11 is released to restore the U-shaped spring piece 9 to its initial position, and the arc-shaped limit rod 10 is driven by the connecting rod 13 to squeeze the limit tube so that it can better adapt to the spacing of the nostrils. The limit tube 4 is made of a harder material to prevent the limit tube 4 from being deformed when the arc-shaped limit rod 10 is squeezed.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
