[0002] Oxygen tubing, a tubular device used to deliver oxygen to patients, plays a crucial role in medical practice. It typically consists of an oxygen inlet port, oxygen hose, adjustment ring, and nasal prongs or a face mask. These components work together to ensure safe and effective delivery of oxygen to the patient's respiratory tract.

[0003] At present, the existing technology adopts the method of nasal plugging in actual application. The diameters of users' nostrils vary. Forcibly plugging the nose will cause discomfort to the patient's nose. Although the mask type can solve the above-mentioned defects, the mask type oxygen inhalation device discharges oxygen into the mask to provide oxygen to the user when in use. Due to the mask type design and the small exhaust holes, most of the turbid air exhaled by the user is retained in the mask. When inhaling, the oxygen mixed with the turbid air is inhaled again, which greatly affects the oxygen concentration. In addition, the continuous oxygen supply in the mask is in a positive pressure state. The oxygen that is not inhaled during exhalation will be discharged through the exhaust holes, causing unnecessary waste. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 The present invention provides an oxygen-saving oxygen absorption device, such as Figure 1 As shown, it includes a soft fixator 1 wrapped around the nose for overall fixation, an oxygen inhalation tube 2 and an oxygen-saving structure.

[0028] The inlet of the oxygen tube 2 is located at the nostril of the flexible holder 1 and the inlet is against the nostril. The air inlet end of the oxygen tube 2 is connected to an external air source. The diameter of the inlet end of the oxygen tube 2 is larger than the nostril, which solves the problem of discomfort caused by inserting the inlet end of the oxygen tube 2 into the nostril and the problem of not being suitable for nostrils of different sizes in the prior art.

[0029] The oxygen-saving structure is installed on the oxygen inhalation tube 2. When inhaling, oxygen enters the air inlet of the oxygen inhalation tube 2 in one direction through the oxygen-saving structure. When exhaling, turbid air is discharged out of the flexible fixator 1 in one direction through the exhaust port of the oxygen-saving structure.

[0030] In specific implementation, Figure 2 As shown, the soft fixator 1 includes a soft nasal mask 101 and a fixing belt 102 connected to the soft nasal mask 101; Figure 5 As shown, the soft nose mask 101 is shaped like a human nose, and the back of the soft nose mask 101 is concave and wrapped around the nose, with the bottom extending to the nostrils and the top extending upward to near the bridge of the nose; the soft nose mask 101 is limited by putting the fixing belt 102 on the head.

[0031] As a further improvement, the fixing strap 102 is installed on the soft nose mask 101 through the adjustment buckle 103. The length of the fixing strap 102 is adjusted by adjusting the buckle 103, so that the device can be used in different head circumference sizes, and the tightness can be adjusted to make the user more comfortable when wearing it.

[0032] As a further improvement, a traction belt 104 is connected to the fixing belt 102, and the other end of the traction belt 104 is connected to the soft nose mask 101 near the upper end to form a triangular relationship with the fixing belt 102 and the soft nose mask 101. Through the triangular relationship, the inhalation port of the oxygen tube 2 can fit closely with the user's nostrils to prevent air leakage and thus achieve the oxygen-saving function.

[0033] The traction belt 104 and the soft nose mask 101 are also connected via an adjustment buckle 103, thereby achieving an adjustment function.

[0034] As a further improvement, a plurality of groups of ventilation holes 105 are provided on the soft nose mask 101 to ensure ventilation and air permeability of the nose covering area.

[0035] It should be noted that the soft nose mask 101 can be made of skin-friendly silicone material, and the fixing strap 102 and the traction strap 104 can be made of elastic or non-elastic strip materials, but are not limited to the above. Those skilled in the art can make appropriate choices and replacements according to actual needs.

[0036] The structure of the adjustment buckle 103 is widely available on the market and is a common method for adjusting belts. Therefore, the adjustment buckle 103 will not be described in detail here. As for the installation method of the fixing belt 102 and the pulling belt 104 on the adjustment buckle 103, it is set accordingly according to the structure of the adjustment buckle 103 selected and will not be described in detail here.

[0037] like Figure 3 As shown, the oxygen-saving structure includes an intake one-way valve 3 installed at the intake end of the oxygen intake tube 2 and an exhaust one-way valve 4 near the intake port of the oxygen intake tube 2, wherein the exhaust one-way valve 4 passes through the soft fixer 1 to discharge the foul air to the outside, thereby realizing one-way intake and one-way exhaust, and the foul air does not flow back and the oxygen does not leak to achieve the effect of oxygen saving.

[0038] like Figure 4 As shown, the exhaust end of the exhaust one-way valve 4 is located on the side of the soft fixator 1, so that the exhaled foul air is discharged to both sides of the nose.

[0039] The oxygen inhalation tube 2 has one or two inhalation ends, which can adapt to different working conditions.

[0040] In one embodiment, the flexible holder 1 and the oxygen inhalation tube 2 are an integrated structure.

[0041] When using the oxygen-saving oxygen inhalation device, the soft fixator 1 is placed on the user's nose, and it is checked whether the inhalation end of the oxygen inhalation tube 2 corresponds to the nostril. Then, the length of the fixing belt 102 is adjusted by adjusting the buckle 103 and put on the user's head until it is adjusted to a suitable and comfortable state. Then, the length of the pulling belt 104 can be adjusted so that the inhalation end of the oxygen inhalation tube 2 is stably fitted to the user's nostril to prevent oxygen leakage.

[0042] When the user inhales normally, external oxygen enters the oxygen inhalation tube 2 through the air inlet one-way valve 3. When exhaling, the air inlet one-way valve 3 stops the entry of oxygen, and the turbid air is discharged through the exhaust one-way valve 4. Similarly, the exhaust one-way valve 4 remains closed during inhalation, which solves the problem of continuous oxygen supply from the oxygen inhalation tube in the prior art and waste caused during exhalation, thereby achieving the function of saving oxygen. In addition, the exhaust one-way valve 4 also acts as a pressure relief valve. When the air intake of the air inlet one-way valve 3 is too large, the excess oxygen is discharged through the exhaust one-way valve 4 to ensure the comfort of the user.

[0043] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0044] 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 scope of protection of the present invention.
