[0002] A nasal oxygen cannula is an oxygen supply tube used in hospitals for patients who have difficulty breathing and need oxygen therapy. Its working principle is to connect one end to an oxygen tank and insert a plug into the patient's nostrils at the other end, so that oxygen can be inhaled into the lungs from the patient's nostrils. Currently, the nasal oxygen cannula commonly used in hospitals mainly adopts an ear-hook type. The plug is inserted into the patient's nostrils, and then the tubes connecting the two ends of the plug are hung on the patient's two ears to fix the plug and prevent the plug from easily falling out of the patient's nostrils. Among them, conventional nasal oxygen cannulas are all equipped with a plug-in tube, which is inserted into the nose to supply oxygen to the nose. However, when the plug-in tube is inserted into the nose, it is easy to damage the mucous membrane of the inner wall of the nose. Therefore, a high-flow nasal oxygen cannula is provided to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0020] See also Figures 1 to 4 A high-flow nasal oxygen cannula comprises an oxygen supply tube 1, an oxygen guide tube 4 is arranged at one end of the oxygen supply tube 1, connecting tubes 403 are fixedly connected to both sides of the oxygen guide tube 4, the oxygen supply tube 1 and the detection tube 5 are spirally connected to both ends of the connecting tube 403, an external tube 2 is fixedly connected and penetrated to one side of the oxygen supply tube 1, a heating tube 3 is fixedly connected and penetrated to one side of the external tube 2, two groups of oxygen supply beads 401 are installed on the oxygen supply tube 4, oxygen supply ports are opened on the oxygen supply beads 401, and a groove 402 is arranged between the two groups of oxygen supply beads 401.

[0021] Among them, oxygen is transported to the inside of the nose by providing an oxygen delivery bead 401 on the oxygen guide tube 4 to replace the traditional insertion tube. The groove 402 arranged therein can be engaged with the position of the nasal septum to fix the position of the oxygen delivery bead 401 inside the nasal cavity. Because the surface of the oxygen delivery bead 401 is hemispherical, it is not easy to collide with the mucous membrane inside the nasal cavity, which can prevent the insertion tube from causing damage to the mucous membrane inside the nose.

[0022] Furthermore, when the oxygen conducting tube 4 is not connected to the oxygen supply tube 1, the connecting tubes 403 at both ends of the oxygen conducting tube 4 are sleeved with ultra-thin hydrocolloid dressings to seal and protect the oxygen conducting tube 4. The ultra-thin hydrocolloid dressings can be uncovered when in use.

[0023] Preferably, both groups of connecting tubes 403 are sleeved with elastic ropes 6 , adjacent ends of the elastic ropes 6 are fixedly connected with restraining belts 602 , adjacent sides of the restraining belts 602 are fixedly connected with adjusting belts 603 , and adjusting buckles 601 are provided between the adjusting belts 603 .

[0024] By wrapping the restraining belt 602 behind the patient's head and fixing the position of the oxygen conducting tube 4 at the nose, the length of the adjusting belt 603 can be adjusted through the adjusting buckle 601 according to the size of the patient's head circumference, so that the patient can wear it more comfortably. The adjustment method between the adjusting buckle 601 and the adjusting belt 603 is the existing technology and will not be described in detail here.

[0025] Furthermore, the adjustment buckle 601 is arranged behind the patient's head, so that the patient can adjust the length of the restraint belt 602 and the adjustment belt 603 conveniently.

[0026] Preferably, the interior of the detection tube 5 is slidably connected to a sliding plate 501 and fixedly connected to a fixed tube 502, one end of the sliding plate 501 is inserted into the interior of the fixed tube 502, a push switch 503 is installed inside the fixed tube 502, a display light 505 is installed on the outside of the detection tube 5, the display light 505 is electrically connected to the push switch 503, and a spring 504 is sleeved on the fixed tube 502.

[0027] Among them, when the air pressure inside the oxygen delivery tube 4 is too high, it will press the sliding plate 501 to move towards the fixed tube 502 until one end of the sliding plate 501 touches the push switch 503. When the push switch 503 is touched, the display lamp 505 will light up, which can remind the medical staff to adjust the flow rate inside the oxygen tube 1.

[0028] Preferably, an input port 301 and an output port 302 are respectively provided inside the heating tube 3. A flow cavity 303 is provided between the input port 301 and the output port 302, and an electric heating wire 304 is provided outside the flow cavity 303.

[0029] Among them, a power input port is installed outside the heating tube 3. During use, the electric heating wire 304 is powered by an external power cord. After the electric heating wire 304 is powered on, it starts to heat. When oxygen and the mixed gas flow into the flow cavity 303 through the input port 301, the electric heating wire 304 can heat the oxygen and the mixed gas inside the flow cavity 303, preventing cold oxygen and the mixed gas from entering the human body and causing discomfort to the patient.

[0030] Preferably, the flow cavity 303 is arranged in a "J" shape.

[0031] Among them, the flow cavity 303 in the shape of a "J" can extend the residence time of oxygen and the mixed gas inside the flow cavity 303, facilitating the electric heating wire 304 to fully heat the oxygen and the mixed gas.

[0032] Preferably, the width of the elastic cord 6 is 4 - 6 cm, and the width of the elastic cord 6 is two-thirds of the width of the restraint band 602.

[0033] Among them, through the elastic cord 6 and the restraint band 602, the diameter is widened. The diameter of the traditional elastic cord 6 is between 3 - 5 cm. The widened elastic cord 6 and restraint band 602 can prevent the elastic cord 6 and the restraint band 602 from leaving marks on the head when worn on the head.

[0034] Working principle: oxygen is transported to the nose by providing oxygen beads 401 on the oxygen conduit 4 to replace the traditional plug-in tube. Since the oxygen beads 401 are hemispherical, the hemispherical oxygen beads 401 are inserted into the nostrils to avoid damage to the mucous membrane inside the nose caused by the plug-in tube and to prevent oxygen leakage. The diameter of the elastic rope 6 and the restraint belt 602 are widened. The diameter of the traditional elastic rope 6 is between 2 and 3 cm. The widened elastic rope 6 and the restraint belt 602 can avoid the elastic rope 6 and the restraint belt 602 from causing marks on the head when worn on the head. When oxygen and the mixed gas flow into the circulation cavity 303 through the input port 301, the oxygen and the mixed gas inside the circulation cavity 303 can be heated by the electric heating wire 304 to avoid the cold oxygen and the mixed gas from entering the human body and causing discomfort to the patient.
