Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an adjustable anesthesia mask. Background Technology

[0002] Anesthesia masks are widely used during surgery to administer anesthesia and provide oxygen to patients. Most of the structural components of anesthesia masks are made of transparent plastic, allowing medical staff to easily monitor the patient's condition, such as cyanosis, vomiting, and bleeding.

[0003] Existing anesthesia masks are often inconvenient to adjust according to the patient's head circumference or facial contours during use, which can easily lead to the mask falling off or leaking air, affecting the effectiveness of the device and reducing its applicability. At the same time, existing anesthesia masks do not allow for easy inflation and adjustment of the elastic pad, and patients may develop varying degrees of pressure marks on their faces after wearing the mask for a long time, reducing the comfort of the device and causing a poor experience for the patient. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0028] Preferably, a fog-absorbing plate 6 is installed inside the mask 2, and the fog-absorbing plate 6 is fixedly connected to the upper part of the inside of the mask 2;

[0029] By setting up the fog-absorbing plate 6, the fog inside the inhaled mask 2 can be absorbed, increasing the practicality and convenience of the device.

[0030] Preferably, a limiting plate 17 is installed at one end of the winding rod 10, and the limiting plate 17 is fixedly connected to the winding rod 10.

[0031] By setting the limiting plate 17, the winding rod 10 can be limited and fixed, ensuring the safety of the cable tie 11 on the winding rod 10 and preventing it from falling off.

[0032] Preferably, the outer wall of the knob 15 is provided with anti-slip grooves 16, and multiple sets of anti-slip grooves 16 are provided.

[0033] By setting the anti-slip groove 16, it is convenient for users to rotate and adjust the knob 15, and to prevent the user's hand from slipping while rotating the knob 15.

[0034] Preferably, a support frame 13 is fitted onto the worm gear 12, and one end of the support frame 13 is fixedly connected to the mask 2.

[0035] By setting up the support frame 13, the stability of the worm gear 12 is increased, ensuring the safety of the worm gear 12 during use.

[0036] Preferably, one end of the cover plate 21 is connected to an elastic band 23, and a limit ring 24 is connected below the elastic band 23. The limit ring 24 is fixedly sleeved on the inflatable core 19.

[0037] By setting the elastic band 23 and the limiting ring 24, the cover plate 21 can be fixed and limited, preventing the cover plate 21 from falling off the inflatable core 19.

[0038] Preferably, a handle 22 is connected to one end of the cover plate 21, and the handle 22 is fixedly connected to the cover plate 21.

[0039] By providing a handle 22, users can easily open and close the cover 21, increasing the practicality and convenience of the device.

[0040] The working principle and usage process of this utility model are as follows: In use, the patient first places the harness 11 over their head, then puts the mask 2 on their face. The patient then turns the knob 15, which rotates the worm gear 12. The worm gear 12 rotates, which in turn rotates the meshing worm wheel 9. The worm wheel 9 rotates, which in turn rotates the winding rod 10. The winding rod 10 rotates, which in turn rotates the harness 11, which is fixed to it. The harness 11 is wound up during this rotation until it fits the patient's head circumference. Conversely, the tightness of the harness 11 can be adjusted according to the individual's head circumference and face shape, making the mask 2 fit the facial contours better, enhancing comfort and protective effect, and ensuring the safety and stability of the device during use. To avoid fatigue and discomfort during prolonged wear, when the inflatable elastic pad 18 needs to be inflated during use, the user can open the cover 21 upwards using the handle 22. During this process, the user can pull the sealing plug 20 out of the inflation core 19. After pulling it out, the user can inflate the inflatable elastic pad 18 through the inflation core 19. After inflation, the cover 21 and sealing plug 20 can be reset. This allows the user to adjust the inflation of the elastic pad 18 according to their needs, which helps the mask 2 fit the patient's facial contours tightly, reduces gas leakage, ensures effective delivery of anesthetic gas, improves the anesthetic effect, enhances the comfort of the device, reduces the pressure of the mask 2 on the patient's face, and meets the needs of different patients.
