[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 , Figure 3 and Figure 4 , an embodiment provided by the utility model: a disposable humidified nasal oxygen tube assembly, comprising a connecting tube 1, both ends of the connecting tube 1 are fixedly connected with a heat-conducting tube 3 through a heat-insulating pad 2, the heat-insulating pad 2 is used to isolate heat transfer or reduce heat conduction, to prevent the connecting tube 1 from being deformed by heat and affecting normal use, and the connecting tube 1 and the heat-conducting tube 3 are in communication, so that oxygen can be heated to a certain degree through the heat-conducting tube 3, to prevent oxygen from entering the patient's nose and causing discomfort, the outer wall of the connecting tube 1 is provided with a ring 4, the inner wall of the ring 4 is provided with a positioning mechanism, the top of the ring 4 is provided with a heater 7, the heater 7 has electronic components, and the electric heating wire in the bracket 8 can be heated to a certain temperature by electricity, and the heating temperature is between fifteen degrees and twenty-five degrees, to prevent the patient from feeling uncomfortable due to the unheated oxygen in cold weather, the heater 7 A bracket 8 is provided at the top, and the top of the bracket 8 is an arc surface, which can allow the bracket 8 to contact the outer wall of the heat-conducting tube 3 to transfer heat. A heating wire is provided in the bracket 8. The heating wire is a prior art and will not be described in detail here. The heating wire is a conductive wire, usually made of alloy or metal, has a high resistivity, and generates heat by energizing. A wiring harness 9 is provided on the outer wall of the heater 7, and the heater 7 is operated by plugging the wiring harness 9 with an external device. The left end of the connecting tube 1 is fixedly connected with a socket 10, and the socket 10 can be connected to the port of the humidification bottle. The right end of the connecting tube 1 is fixedly connected with a mobile sleeve 11, and the mobile sleeve 11 has a cavity inside, which can allow oxygen to pass through the mobile sleeve 11 from the nasal tube 12 to the patient's nose. The outer wall of the mobile sleeve 11 is fixedly connected with the nasal tube 12, and the nasal tube 12 is plugged into the patient's nose to allow oxygen to enter the patient's nose from the nasal tube 12.

[0031] Reference Figure 1 and Figure 2The outer wall of the mobile sleeve 11 is detachably mounted with a sleeve 13. The sleeve 13 can be separated from the mobile sleeve 11 and can be subsequently disinfected and used continuously. After the sleeve 13 and the mobile sleeve 11 are installed, the mobile sleeve 11 can be slid along the inner wall of the sleeve 13. The outer wall of the mobile sleeve 11 is slidably connected with a card block 14. The outer wall of the sleeve 13 is provided with a card slot 15. The card slot 15 is divided into a horizontal opening and a vertical opening. The vertical opening can position the card block 14 so that the card block 14 cannot move with the mobile sleeve 11. The card block 14 coincides with the horizontal opening, so that the card block 14 can move with the mobile sleeve 11. Figure 2 As shown, the vertical opening has an opening, which allows the clamping block 14 to be moved out from the opening, and the clamping block 14 is clamped with the inner wall of the clamping slot 15.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The positioning mechanism includes a movable plate 6, and an arc plate is provided at the left end of the movable plate 6. The entire circular ring 4 is positioned by contacting the arc plate with the heat-conducting tube 3. There is a gap between the upper ends of the movable plate 6. The medical staff touches the movable plate 6 with their hands to move the movable plate 6. The movable plate 6 is elastically connected to the outer wall of the circular ring 4 through a return spring 5. The movable plate 6 penetrates and is slidably connected to the inner wall of the circular ring 4. The inner side wall of the movable plate 6 is fixedly connected to one end of the return spring 5. At this time, the return spring 5 is in a stretched state. When the left end of the movable plate 6 is not in contact with the heat-conducting tube 3, the elastic force of the return spring 5 is used to return the movable plate 6. The other end of the return spring 5 is fixedly connected to the outer wall of the circular ring 4. The left end of the movable plate 6 contacts the outer wall of the heat-conducting tube 3, and the top of the bracket 8 contacts the outer wall of the heat-conducting tube 3.

[0033] Working principle: First, when the nasal tube 12 needs to be adjusted according to the size of the patient's nose, it is only necessary to move the card block 14 upwards to make the horizontal openings of the card block 14 and the card slot 15 overlap, so that the card block 14 can bring the movable sleeve 11 and the nasal tube 12 closer to each other, and adjust according to the patient's nose distance. When positioning is required, it is only necessary to move the card block 14 downwards to make the vertical openings of the card block 14 and the card slot 15 overlap and engage, so as to complete the positioning of the movable sleeve 11 and the nasal tube 12.

[0034] When supplying oxygen to the patient, it is only necessary to connect the socket 10 with the port of the humidification bottle, and then connect the wiring harness 9 with the external device to operate the heater 7. Electricity is provided to the heating wire in the bracket 8, and the heat of the heating wire is transferred to the bracket 8, so that the oxygen passing through the bracket 8 can be heated to prevent the oxygen from entering the patient's nose in cold weather and causing discomfort. The heater 7 can be turned off at any time when not in use.

[0035] After the use of the connecting tube 1 is finished, the block 14 and the slot 15 can be completely separated by pulling the block 14 out of the vertical opening of the slot 15, so that the movable sleeve 11 is separated from the sleeve 13, and then the movable plate 6 is moved by hand so that the arc plate at the left end of the movable plate 6 is no longer in contact with the heat-conducting tube 3, and then the ring 4 and the connecting tube 1 are separated from the heat-conducting tube 3. The entire ring 4 and the sleeve 13 can be divided into individuals and can be used again after subsequent disinfection. After the single use, the connecting tube 1 can be discarded to the processing center at any time.

[0036] After the entire sleeve 13 and the ring 4 have been disinfected, they can be put into use again. Simply follow the steps in the third paragraph to install the sleeve 13 and the movable sleeve 11, and adjust the position of the block 14 as shown in the figure. Figure 2 As shown, when installing the ring 4, it is only necessary to move the movable plate 6 in advance to compress the reset spring 5, insert the ring 4 from the connecting pipe 1, let the heat pipe 3 contact with the bracket 8, loosen the movable plate 6, use the reverse elastic force of the reset spring 5 to reset the movable plate 6, and let the movable plate 6 contact with the heat pipe 3 to position the entire ring 4.

[0037] 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.
