Description

Technical Field

[0001] This application belongs to the technical field of anesthetic devices, and particularly relates to an anesthetic mask. Background Art

[0002] An anesthetic mask is an essential tool for general anesthesia. The anesthetic mask can cover the patient's mouth and nose, be connected to an anesthesia machine through an anesthesia pipeline, and provide an effective non-invasive breathing circuit for the patient. When anesthetizing a patient, in order to prevent the patient's tongue from falling back, it is necessary to use an oropharyngeal airway in cooperation. After the patient is given general anesthesia, a common anesthetic mask is used to pressurize and supply oxygen to maintain oxygen supply. Some patients (commonly obese patients) will have severe tongue falling back.

[0003] For example, a patent CN219896698U provides an anesthetic mask. Through the first connecting pipe provided on the mask body, it can be connected to the third connecting pipe at the flange of the oropharyngeal airway, so that when anesthetizing a patient, the oropharyngeal airway can be connected and fixed to the mask body of the anesthetic mask. When a doctor presses the mask by hand or fixes the mask on the patient's face with tape, the oropharyngeal airway can be fixed.

[0004] However, in special cases, it is necessary to insert a fiberoptic bronchoscope into the nasal cavity of an anesthetized patient. The mask in the above patent is oval as a whole, and when worn on the patient, it will cover the patient's mouth and nose, making it impossible to operate on the nasal cavity during normal use. Summary of the Utility Model

[0005] This application provides an anesthetic mask to solve the technical problem that a traditional mask covers the mouth and nose, resulting in the inability to operate on the nasal cavity.

[0006] To solve the above technical problem, a technical solution adopted by this application is: an anesthetic mask, including a mask and an oropharyngeal component; the mask is crescent-shaped and has a threaded port in the middle. The threaded port is provided with a fixed pipe, the middle of the fixed pipe is threaded, and the side of the fixed pipe close to the face is movably connected to the oropharyngeal component.

[0007] Further, the oropharyngeal component includes a tooth block and an oropharyngeal trachea. A through hole is provided in the tooth block. One side of the through hole is movably connected to the oropharyngeal trachea, and the other side of the through hole is snap-connected to the fixed pipe.

[0008] Further, an elastic layer is provided on the outer wall of the tooth block.

[0009] Further, a snap ring is provided at the end of the fixed pipe close to the tooth block.

[0010] Further, a card slot corresponding to the snap ring is provided on the inner wall of the through hole.

[0011] Further, fixing straps are provided on both sides of the face mask. Hook surfaces of Velcro are respectively provided at the ends of the fixing straps on one side, and loop surfaces of Velcro are respectively provided at the ends of the fixing straps on the other side.

[0012] The beneficial effects of the present application are as follows: By changing the traditional oval face mask to a crescent-shaped face mask, the nasal cavity of the patient can be exposed through the crescent notch part, but it can fit the mouth, ensuring the wearing effect of the face mask. At the same time, both the fixing tube and the oropharyngeal airway can be freely disassembled, which is convenient for fixing the patient through the face mask after oropharyngeal intubation and preventing the oropharyngeal airway from slipping out of the patient's larynx.

[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application.

[0018] As Figures 1-4 shown, an anesthesia face mask 1 includes a face mask 1 and an oropharyngeal assembly 2; the face mask 1 is crescent-shaped and a threaded port 11 is provided in the middle. The threaded port 11 is provided with a fixing tube 3, the middle of the fixing tube 3 is threaded, and the side of the fixing tube 3 close to the face is movably connected to the oropharyngeal assembly 2. The crescent-shaped face mask 1 in the above design can fit the mouth while exposing the nasal cavity outside. The fixing tube 3 is connected to the threaded port 11 through threads, and an external oxygen pipeline can be connected to the outside of the fixing tube 3, so that oxygen is delivered to the patient's mouth through the fixing tube 3. In other embodiments, a groove can also be provided on one side of the oval face mask 1 to expose the patient's nasal cavity.

[0019] The oropharyngeal assembly 2 includes a tooth block 21 and an oropharyngeal trachea 22. A through hole 23 is provided in the tooth block 21. One side of the through hole 23 is movably connected to the oropharyngeal trachea 22, and the other side of the through hole 23 is connected to the fixed tube 3. In the above design, the tooth block 21 is movably connected to the oropharyngeal trachea 22 and the fixed tube 3, so as to facilitate the fixation of the oropharyngeal trachea 22. In this embodiment, the end of the oropharyngeal trachea 22 is inserted into the through hole 23 through an interference structure, that is, the outer diameter of the oropharyngeal trachea 22 is slightly larger than the inner diameter of the through hole 23, so that the oropharyngeal trachea 22 can be firmly inserted into the through hole 23.

[0020] An elastic layer is provided on the outer side wall of the tooth block 21. In the above design, the tooth block 21 spreads open the patient's tooth gaps, and the elastic layer prevents damage to the patient's teeth and mouth during the intubation process.

[0021] A clamping ring 31 is provided at the end of the fixed tube 3 close to the tooth block 21. In the above design, the clamping ring 31 facilitates the clamping of the tooth block 21, so that the fixed tube 3 can be connected to and separated from the tooth block 21.

[0022] A clamping groove 24 corresponding to the clamping ring 31 is provided on the inner wall of the through hole 23. In the above design, the clamping groove 24 is used to clamp the clamping ring 31, so as to complete the connection of the fixed tube 3. In other embodiments, the connection between the fixed tube 3 and the through hole 23 can use an interference structure for insertion.

[0023] Fixing straps 4 are provided on both sides of the mask 1. Hook surfaces of Velcro 41 are respectively provided at the ends of the fixing straps 4 on one side, and loop surfaces of Velcro 41 are respectively provided at the ends of the fixing straps 4 on the other side. In the above design, the fixing straps 4 are used to fix the entire mask 1 around the patient's mouth. In other embodiments, the ends of the fixing straps 4 can be connected by buckles or tying methods, and are selected according to the actual situation.

[0024] For the specific usage method, when anesthetizing a patient, first insert the oropharyngeal trachea 22 into the patient's larynx, then insert the tooth block 21 at the end of the oropharyngeal trachea 22 and place the tooth block 21 between the patient's teeth. Then screw the fixed tube 3 into the threaded port 11 of the mask 1, and snap the inner end of the fixed tube 3 onto the tooth block 21. The notch part of the mask 1 is aligned with the nasal cavity, so that the nasal cavity is exposed and the mouth is completely wrapped. Finally, fix the mask 1 on the patient's face through the fixing straps 4.

[0025] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied to other related technical fields, are equally included in the patent protection scope of the present application.
