[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In this embodiment, the present invention provides a retractable atomizing inhalation mouthpiece device, such as... Figure 1 and Figure 2 As shown, the device includes a nebulizer cup 1, which has a filling chamber for dispensing medication. A lid 11 covers the opening of the filling chamber. The filling chamber is used to dispense the medication to be nebulized. The lid 11 is closed to prevent the medication from overflowing if the nebulizer cup 1 is tilted. Additionally, an oxygen inlet (not shown in the figure) is provided on the top side wall of the nebulizer cup 1. This inlet serves as the interface for an external oxygen input pipe and can be a flange connection. It should be noted that this inlet connects to the oxygen input pipe to provide sufficient oxygen to the patient's mouth and nose during nebulization, with the mask covering the patient's face.

[0022] The atomizing cup 1 has an enlarged external end 12 on one side wall. The enlarged external end 12 is detachably connected to a telescopic adjustment component. The length of the telescopic adjustment component is adjustable, and the end of the telescopic adjustment component is connected to a mouthpiece body 22.

[0023] The telescopic adjustment component is a telescopic tube 2, which has a corrugated telescopic section 21. The telescopic tube 2 is made of polycarbonate and consists of an enlarged external end 12, the telescopic adjustment component, and the mouthpiece body 22, forming an adjustable length atomization channel. This allows the connection length between the mouthpiece body 22 and the atomizing cup 1 to be adjustable, making it convenient for patients to use in different positions and scenarios.

[0024] During nebulization, the telescopic section 21 is stretched or compressed according to the patient's position, making the connection length between the mouthpiece 22 and the nebulizer cup 1 adjustable. The telescopic tube 2 serves as a hollow connecting medium between the mouthpiece 22 and the nebulizer cup 1, allowing the nebulized drug particles to pass through. Patients can control the stretching or compression of the telescopic section 21 according to their usage needs, making it convenient for patients to use in different positions and scenarios, reducing the difficulty of patient care, and improving patient comfort and clinical efficacy.

[0025] By adjusting the length of the telescopic section 21, it can adapt to the patient's needs in different positions and scenarios. For example, when a bedridden patient uses it at the head of the bed, the telescopic section 21 can be extended so that the patient can use it easily without adjusting their position.

[0026] Furthermore, the telescopic tube 2 here is made of polycarbonate, which has good support strength and prevents the telescopic section 21 from being compressed in a normal state, thus affecting the path of the nebulized medicine. It also has good elasticity and flexibility, allowing for bending, stretching, or contraction according to different patient positions to meet the patient's needs. Of course, the telescopic adjustment component is not limited to the aforementioned telescopic tube 2; a spliced ​​tubing system can also be used. That is, according to the required nebulization length, multiple disposable sterile tubes can be sequentially connected to form a longer nebulization path to meet the nebulization requirements.

[0027] Meanwhile, the end of the mouthpiece 22 is designed with a flat, rounded opening to accommodate the differences in mouth shapes among different patients, thereby optimizing the user experience and sealing effect.

[0028] In summary, the adjustable nebulization pathway described above allows for wide application in nebulized inhalation therapy for postoperative patients, particularly those who are bedridden and have limited mobility. This provides a more convenient nebulized inhalation treatment option and improves the efficiency of medical staff. Patients can easily use nebulized inhalation therapy in different positions, enhancing treatment effectiveness and comfort. Furthermore, its simple structure and ease of manufacturing and maintenance contribute to improved quality of medical care.

[0029] In this embodiment, as Figure 3 As shown, an extension tube 13 is provided inside the enlarged outer end 12, providing an inlet passage for the atomized liquid to enter the telescopic adjustment component from the enlarged outer end 12. Specifically, sleeves are connected to both opposite side walls of the enlarged outer end 12. One end of the telescopic tube 2 is tightly fitted to the tail end of the mouthpiece body 22, and the other end of the telescopic tube 2 is tightly fitted to one of the sleeves of the enlarged outer end 12. An atomizing hole is opened at the top of the side wall of the atomizing cup 1, and the other sleeve of the enlarged outer end 12 is tightly inserted into the atomizing hole. Meanwhile, the enlarged outer end 12 has a hollow spherical structure with a diameter larger than the diameter of the atomizing hole. One end of the extension tube 13 is an enlarged opening connected to the end of a sleeve installed on the telescopic tube 2, and the other end of the extension tube 13 is a narrowed opening 131, which is one-fifth to one-third the diameter of the atomizing hole. A narrowing channel 132 is provided in the middle section of the extension pipe 13, and the inner diameter of the narrowing channel 132 is smaller than the inner diameter of the narrowing opening 131. The above describes the specific installation position of the extension pipe 13 within the enlarged external connection end 12.

[0030] from Figure 3 It can be clearly seen that after the atomized medicine enters the enlarged external end 12 through the atomization hole, it gathers in the enlarged external end 12 and continues to flow along the extension tube 13 through the narrowing opening 131. At this time, it will pass through the narrowing channel 132 and finally smoothly enter the telescopic adjustment component and mouthpiece body 22. Finally, it enters the patient's mouth and nose through the flat round arc opening of the mouthpiece body 22 to achieve the purpose of atomization.

[0031] In actual use, when the atomizing cup 1 tilts, the un-atomized medicine will overflow into the enlarged outer end 12. Since the diameter of the enlarged outer end 12 is larger than the diameter of the atomizing hole, the space inside the enlarged outer end 12 is relatively larger. Therefore, the un-atomized medicine will first fill the enlarged outer end 12, which helps to prevent the un-atomized medicine from directly entering the telescopic adjustment component. Secondly, the design position of the narrowing opening 131 of the extension pipe 13 is at the same height as the center inside the enlarged outer end 12. Therefore, only when the liquid level in the enlarged outer end 12 reaches the height of the narrowing opening 131 can the un-atomized medicine enter the telescopic adjustment component through the extension pipe 13.

[0032] Clinically, the volume of medication in a single nebulization is small, typically 2-8 ml. The applicant has set the internal volume of the enlarged external end 12 to be over 20 ml, and the volume of medication at the height of the narrowed opening 131 to be half of 20 ml. This ensures that the enlarged external end 12 has sufficient space to hold the medication, preventing it from overflowing into the telescopic adjustment mechanism. Without affecting the smooth passage of the nebulized medication, this design prevents the medication from passing unimpeded through the telescopic adjustment mechanism and mouthpiece 22 into the mouth and nose when the nebulizer cup 1 is tilted, thus improving patient comfort and clinical efficacy.

[0033] Meanwhile, the design of the narrow channel 132 prevents the liquid from splashing into the narrow opening 131 when the atomizing cup 1 is tilted. At this time, the narrow channel 132 can block a large amount of liquid from splashing into the telescopic adjustment component with a smaller internal space.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
