Description

Technical Field

[0001] This utility model relates to the field of oxygen mask technology, specifically a dual-function mask that can provide positive pressure ventilation and atomization. Background Technology

[0002] Nebulized inhalation via face mask allows for the administration of local anesthetics such as lidocaine before induction of general anesthesia, reducing the dosage of general anesthetic drugs required for induction, minimizing reactions during laryngoscopy and intubation, and maintaining stable vital signs during induction. Simultaneously, during emergency endotracheal intubation, pre-oxygenation can be performed, with lidocaine and other local anesthetics administered via nebulization while inhaling oxygen, further reducing reactions during laryngoscopy and intubation, minimizing the need for medication during emergency intubation, and reducing the impact on the patient's circulation. Nebulized inhalation of corticosteroids can also alleviate high airway reactivity, reduce airway spasm and asthma attacks, thin sputum, and prevent respiratory infections. Due to its advantages such as rapid onset of action, low dosage, high local drug concentration, and few systemic adverse reactions, nebulized inhalation has become an important adjunctive treatment measure in preventing postoperative pulmonary complications.

[0003] Existing dual-channel masks are all designed for use in respiratory medicine. One channel connects to a nebulizer, and the other connects to an oxygen or artificial respiration mask. While both can simultaneously administer medication and oxygen, the oxygen concentration cannot be too high to rapidly increase the patient's partial pressure of oxygen during resuscitation, thus limiting the time available for intubation or resuscitation. Furthermore, when the second inlet is not in use, it cannot function as a positive pressure ventilation mask, requiring mask replacement, which is cumbersome and disrupts the normal treatment or resuscitation process. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a dual-function mask that can provide positive pressure ventilation and atomization, so as to solve the technical problem that when using it for a long time, the position of the cap may be forgotten, and the cap needs to be found when it is needed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-function mask capable of positive pressure ventilation and atomization, comprising a mask body, wherein the mask body includes a first ventilation port and a second ventilation port, a sealing cap is rotatably connected to the second ventilation port, and a sealing plug is provided at the bottom of the sealing cap.

[0006] By adopting the above technical solution, dual functions of positive pressure ventilation and nebulization are achieved, meeting the needs of users in different treatment scenarios. The first ventilation port on the mask body can be connected to a positive pressure ventilation device, such as a ventilator, to provide users with continuous airflow support, ensuring that users can receive timely assistance when they have difficulty breathing or need assisted breathing. The second ventilation port provides users with the function of nebulization therapy. When nebulization therapy is needed, simply open the sealing cover to expose the second ventilation port and connect it to the adapter mechanism.

[0007] Furthermore, the second vent is internally provided with a switching mechanism, which includes a switching connector body.

[0008] By adopting the above technical solution, the mask cleverly incorporates an adapter mechanism inside the second ventilation port. The core component of the adapter mechanism is the adapter body, which can be stably and effectively connected to different medical devices, such as nebulizers. It can provide nebulization treatment according to specific treatment needs without replacing the entire mask, thereby saving time and costs.

[0009] Furthermore, a first connecting shell is rotatably connected to one end of the adapter body, and a second adapter shell is rotatably connected to the other end of the adapter body.

[0010] By adopting the above technical solution, one end of the adapter body is rotatably connected to the first connecting shell, so that when the adapter mechanism is connected to the second vent of the mask body, the angle and position can be adjusted according to actual needs. The first connecting shell and the second adapter shell at both ends of the adapter body can rotate freely 360 degrees, so that it can be rotated to any position, improving the adaptability of use.

[0011] Furthermore, the adapter body has a "7" shaped structure, and a sealing cap is provided on the top of the adapter body; a gas hole for inflating the airbag is provided on one side of the mask body.

[0012] By adopting the above technical solution, the adapter body is designed with a "7" shaped structure. When the adapter is connected to the second air vent of the mask body, the "7" shaped structure can keep the other end of the connected atomizer horizontal, ensuring the reliability of the atomized gas output.

[0013] Furthermore, a hook is provided on one side of the sealing cover, and a lever is provided on one side of the hook, the lever having a "Z" shaped structure.

[0014] By adopting the above technical solution, a hook is fixedly connected to one side of the sealing cover, realizing a stable connection between the sealing cover and the mask body. When the sealing cover is closed, the hook can tightly lock the corresponding structure on the mask body, ensuring that the sealing cover will not be easily opened by external force, thereby maintaining the sealing of the mask and the stability of the treatment environment.

[0015] Furthermore, the top of the first connecting shell is provided with slots around its perimeter. The slots are arranged in a triangular structure, and there are multiple slots arranged in a ring evenly.

[0016] By adopting the above technical solution, slots are opened around the top of the first connecting shell, and these slots are arranged in a triangular structure, so that the slots can reliably achieve the limiting effect.

[0017] Furthermore, both ends of the adapter body are provided with fixing plates, and one end of the fixing plate is provided with a locking block, which is compatible with the locking slot.

[0018] By adopting the above technical solution, a fixing plate is fixedly connected to one side of the adapter body, providing a fixing point for the locking block, enhancing its structural strength and stability, and ensuring that the adapter mechanism will not move easily due to external force after locking.

[0019] Furthermore, a triangular block is provided on one side of the second vent, and the triangular block and the hook form a fixing mechanism.

[0020] By adopting the above technical solution, a triangular block is fixedly connected to one side of the second vent, which, together with the hook, forms a stable fixing mechanism. When the sealing cover is closed, the hook can firmly hook the triangular block, thereby ensuring that the sealing cover will not be easily opened by external force.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model, by setting a sealing cap and an adapter mechanism, can effectively seal the second air vent when it is not needed, thereby maintaining the airtightness and cleanliness of the mask's interior. When the user needs to use the second air vent, simply open the sealing cap to easily expose the second air vent. By inserting the first connecting shell of the adapter mechanism and connecting the second adapter shell to the atomizer's input tube, a flexible connection between the atomizer and the mask is achieved. The adapter mechanism allows the user to continue adjusting after the connection is completed, thereby ensuring a tight fit and stable connection between the atomizer and the mask, improving user comfort, and allowing users to make personalized adjustments according to their needs and habits.

[0023] 2. This utility model provides users with a convenient and stable way to open the sealing cover by setting up a lever, a locking block, and a locking groove. Users only need to press the position of the sealing cover's rotating shaft with their thumb and hook the lever with their index finger and pull it up to easily disengage the locking hook from the triangular block, thereby realizing the function of opening the sealing cover with one hand. This allows users to easily open the sealing cover while holding the adapter mechanism with their other hand, improving the practicality of the mask and the user experience.

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

[0033] Example 1:

[0034] like Figures 1-5As shown, this utility model is a dual-function mask for positive pressure ventilation and nebulization, including a mask body 1. The mask body 1 includes a first ventilation port 2 and a second ventilation port 3. A sealing cover 4 is rotatably connected to the second ventilation port 3. A sealing plug 5 is provided at the bottom of the sealing cover 4. The sealing cover 4 and the sealing plug 5 enhance the sealing performance and ease of use of the mask. When the second ventilation port 3 is not needed, the user only needs to rotate the sealing cover 4 to the closed position to ensure the sealing performance of the mask and prevent external air or impurities from entering the mask and affecting the treatment effect or user experience.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the second ventilation port 3 is equipped with an adapter mechanism 6, which includes an adapter body 601. The introduction of the adapter mechanism 6 also improves the ease of use of the mask. Users can easily install and remove the adapter without the assistance of professionals, reducing the risk of equipment damage or treatment accidents caused by improper operation.

[0036] One end of the adapter body 601 is rotatably connected to the first connecting shell 602, and the other end of the adapter body 601 is rotatably connected to the second adapter shell 603. The second adapter shell 603 serves as the part that connects to medical devices such as nebulizers. Its rotatable connection allows users to easily adjust the relative position between the nebulizer and the mask to ensure smooth airflow and comfortable treatment, ensuring that each user can find the most suitable treatment posture for themselves.

[0037] The adapter body 601 has a "7" shaped structure. The top of the adapter body 601 is provided with a sealing cap 604. The mask body 1 has a gas hole 13 on one side for inflating the airbag 14, which improves the sealing and protection capabilities of the adapter mechanism 6. The sealing cap 604 can fit tightly against the top of the adapter body 601 to prevent external air or impurities from entering the interior of the adapter mechanism 6, thereby maintaining the cleanliness and hygiene of the treatment environment.

[0038] The implementation principle of this utility model is as follows: First, when the second air vent 3 is needed, the sealing cover 4 is opened to expose the second air vent 3. Then, the first connecting shell 602 of the adapter mechanism 6 is inserted, and then the second adapter shell 603 is connected to the input tube of the atomizer. With the help of the adapter mechanism 6, the first connecting shell 602 and the second adapter shell 603 in the adapter mechanism 6 can rotate freely 360 degrees on the adapter body 601. This allows for continued adjustment after the adapter mechanism 6 is connected, and the atomizer can be connected to the mask more flexibly, improving the applicability and comfort of the mask.

[0039] Example 2:

[0040] It is basically the same as Example 1, except that... Figure 4 and Figure 5 As shown, a hook 7 is provided on one side of the sealing cover 4, and a lever 8 is provided on the other side of the hook 7. The lever 8 has a "Z" shaped structure. The hook 7 is also fixedly connected to the lever 8 with a "Z" shaped structure, which allows the user to easily open or close the sealing cover 4 by moving the lever 8. The "Z" shaped structure gives the lever 8 better mechanical performance and operating feel, so that the user can feel obvious feedback and resistance changes when moving it, thereby more accurately controlling the opening and closing state of the sealing cover 4.

[0041] The top of the first connecting shell 602 has slots 9 around its perimeter. The slots 9 are triangular in structure and there are multiple slots 9 arranged in a ring. This arrangement of multiple slots 9 in a ring allows the adapter 6 to have more options when connecting. Users can adjust the relative position and angle between the adapter 6 and the mask body 1 according to their actual needs.

[0042] Both ends of the adapter body 601 are provided with fixing plates 10. One end of the fixing plate 10 is provided with a locking block 11, which is adapted to the locking groove 9. One end of the fixing plate 10 is also fixedly connected to the locking block 11, and the locking block 11 is adapted to the locking groove 9, thus realizing a stable connection between the adapter mechanism 6 and the first connecting shell 602. When the adapter mechanism 6 is connected to the first connecting shell 602, the locking block 11 can be locked into the locking groove 9 to play a fixing role.

[0043] A triangular block 12 is provided on one side of the second vent 3. The triangular block 12 and the hook 7 form a fixing mechanism. The fixing mechanism formed by the triangular block 12 and the hook 7 also makes the operation of the sealing cover 4 more convenient. Users can easily open or close the sealing cover 4 by simply hooking or releasing the hook 7 onto or from the triangular block 12.

[0044] The implementation principle of this utility model is as follows: First, when it is necessary to open the sealing cover 4, press the position of the rotating shaft of the sealing cover 4 with your thumb, and then hook the lever 8 with your index finger and pull up the lever 8 so that the hook 7 can disengage from the triangular block 12. This allows the sealing cover 4 to be opened with one hand while holding the adapter mechanism 6 with the other hand. At the same time, the engagement of the hook 7 and the triangular block 12 also provides sufficient clamping force to ensure that the sealing cover 4 can maintain a stable seal when closed.

[0045] After connecting the adapter mechanism 6, rotate it to one side. At this time, the locking block 11 locks the locking slot 9, so that the adapter body 601 can be fixed at a suitable angle. At this time, due to its own 7-shaped structure, one end of the adapter body 601 can keep the other end horizontal. Then the second adapter shell 603 at the other end rotates freely, so that it can automatically droop under the action of gravity, ensuring that it can maintain a vertical state, thereby facilitating the normal movement of gas.

[0046] Example 3:

[0047] It is basically the same as Example 2, except that... Figure 6 As shown, a hook-and-loop ring 15 is fitted on the mask body 1. The hook-and-loop ring 15 includes a collar 151 and four rope hooks 152 are arranged around the collar 151. By adding a hook-and-loop ring 15 that can be fitted on the mask body 1, a temporary fixing strap can be added when needed to reliably fix the mask body 1.

[0048] The implementation principle of this utility model is as follows: First, when the hook and loop 15 is fitted onto the first ventilation port 2, the strap is hooked onto the four rope hooks 152 and then wrapped around the back of the patient's head, so as to improve the fixation effect of the mask body 1.

[0049] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
