[0020] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0021] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a nasopharyngeal necrosis flushing syringe, including a syringe 1, which includes a sleeve 11 and a push rod 12 sealingly and slidably connected to the inside of the sleeve 11, a piston is arranged at the end of the push rod 12 placed in the sleeve 11, and a liquid outlet 111 is arranged at the front end of the sleeve 11.

[0024] The outlet 111 is connected with a flushing pipe 2, which includes a straight pipe section 21 and a curved pipe section 22 integrally formed of hard plastic, and the angle between the straight pipe section 21 and the curved pipe section 22 is an obtuse angle. Specifically, one end of the straight pipe section 21 away from the curved pipe section 22 is threadedly connected to the outlet 111.

[0025] When the nasopharyngeal necrosis flushing syringe of this embodiment is in use, the curved tube section 22 can be directly extended into the nasal cavity to reach the nasopharynx, and the liquid medicine in the syringe 1 can be sprayed into the nasopharynx through the flushing tube 2, so that the liquid medicine directly acts on the necrotic position of the nasopharynx, thereby improving the flushing effect. The syringe 1 is threadedly connected to the flushing tube 2, and during use, the syringe 1 can be separated from the flushing tube 2 to facilitate the replenishment of liquid medicine into the syringe 1, and the nasopharynx can be flushed continuously for multiple times.

[0026] It should be noted that the syringe 1 of this embodiment is an existing screw-type syringe. When the drug solution is absorbed, the needle is connected to the liquid outlet 111. After the drug solution is absorbed, the needle can be removed and the flushing tube 2 can be threadedly connected to the syringe 1 for flushing.

[0027] Furthermore, a limiting member 23 is provided on the outer periphery of the straight tube section 21, and the limiting member 23 includes a baffle portion 231 abutting against the outer side of the nose and a nasal plug portion 232 cooperating with the inner periphery of the nostril, and the baffle portion 231 and the nasal plug portion 232 are integrally formed with a silicone material. The inner periphery of the nasal plug portion 232 is adapted to the outer periphery of the straight tube section 21, and a clamping ring 233 is protrudingly provided on the inner periphery of the baffle portion 231, and the clamping ring 233 protrudes from the inner periphery of the nasal plug portion 232. An annular groove is provided on the outer periphery of the straight tube section 21, and the clamping ring 233 is embedded in the annular groove. In this embodiment, the annular groove is used to limit the position of the limiting member 23 in the length direction of the flushing tube 2.

[0028] Specifically, the baffle portion 231 is rectangular and is used to abut against the outside of the nose to limit the maximum depth of the irrigation tube 2 extending into the nasal cavity, and the limiter 23 is engaged with the straight tube section 21 in the axial direction and in the circumferential direction. During use, the angle of the limiter 23 can be adjusted so that it can abut against the outside of the nose normally and prevent it from affecting the insertion of the irrigation tube 2 into the nasal cavity.

[0029] Furthermore, the above-mentioned nasal plug portion 232 includes an arc segment 2321 and a tapered segment 2322 in sequence along the direction away from the baffle portion 231. The tapered segment 2322 is gradually tapered along the direction away from the baffle portion 231. The outer diameter of the arc segment 2321 first increases and then decreases along the direction away from the tapered segment 2322, so that the nasal plug portion 232 can smoothly extend into the nasal cavity and cooperate with the inner wall of the nostril to prevent the irrigation tube 2 from slipping out of the nasal cavity.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
