[0068] The adjustable mandibular support is a device used to assist the human body in breathing. During anesthesia surgery, the patient needs to be assisted in breathing due to the effect of anesthesia; during the process of assisted breathing, the ventilator needs to be connected to the patient's mouth and nose, and during the connection process, the medical staff needs to adjust and fix the patient's mandible; during this process, the medical staff needs to use their hands to fix the patient's mandible.

[0069] The adjustable mandibular support frame in the related art is mainly used in the case where the patient lies flat during surgery. However, in some surgeries, the patient needs to lie on his side or in other postures. The existing mandibular support frame cannot stably adjust and fix the patient's mandible.

[0070] Based on this, in order to improve the technical problem in the related art that the patient's mandible and mask cannot be adjusted and fixed during surgery such as the patient lying on his side, the embodiments of the present application provide the following solution.

[0071] Please also read Figure 1 The embodiment of the present application provides an adjustable mandibular support frame 100, which includes a mandibular support frame body 10, a mandibular adjustment portion 20, a mask adjustment portion 30 and a mask portion 40; wherein:

[0072] The main body 10 of the chin support frame has a neck wearing space 110 .

[0073] The mandibular adjusting portion 20 is disposed on the mandibular supporting frame main body 10 , and the adjustable portion of the mandibular adjusting portion 20 is located on a side of the mandibular supporting frame main body 10 close to the mandible.

[0074] The mask adjusting portion 30 is rotatably disposed on the mandibular support frame main body 10 .

[0075] The mask portion 40 is disposed at one end of the mask adjustment portion 30 facing away from the mandibular support frame main body 10 .

[0076] Among them, the main body 10 of the mandibular support frame is used to be installed on the patient's neck through the neck wearing space 110, and the mask adjustment part 30 is adjusted so that the mask part 40 can cover the patient's mouth and nose, and the mandibular adjustment part 20 is adjusted so that the adjustable part can press against the patient's mandible.

[0077] It can be understood that the main body 10 of the mandibular support frame is a component for setting the mandibular adjustment part 20, the mask adjustment part 30 and the mask part 40 and fixing it to the patient's neck; the main body of the mandibular support part can be a circular shell or a circular ring body. The mandibular adjustment part 20 is a component for adjusting and fixing the patient's mandible; the mandibular adjustment part 20 can be an air bag that can be inflated and deflated or a rubber part that can be adjusted up and down. The mask adjustment part 30 is a component for adjusting the mask part 40; for example, the mask adjustment part 30 can be a component that cooperates with a rotating adjustment part 31 and a moving adjustment part 32, and the mask part 40 can cover the patient's mouth and nose by adjusting the rotating adjustment part 31 and the moving adjustment part 32 in sequence; for another example, the mask adjustment part 30 can also be a rotatable telescopic adjustment part 33, and the mask part 40 can cover the patient's mouth and nose by first adjusting the angle of the telescopic adjustment part 33 and then adjusting the length of the telescopic adjustment part 33. The mask portion 40 is a component used to connect the patient's mouth and nose to the breathing assistance device; the mask portion 40 can be an elliptical shell or an elliptical cover body, etc.

[0078] As can be seen from the above, the adjustable mandibular support frame 100 provided in the embodiment of the present application can, when in use, match the patient's neck with the neck wearing space 110 so that the mandibular support frame main body 10 can be fixed on the neck, thereby enabling the adjustable mandibular support frame 100 to be stably fixed on the patient's neck in different postures; since the mask adjustment portion 30 is rotatably arranged on the mandibular support frame main body 10, and the mask portion 40 is arranged at one end of the mask adjustment portion 30 facing away from the mandibular support frame main body 10, after the mandibular support frame main body 10 is sleeved on the patient's neck, the mask adjustment portion 30 can be rotated and adjusted so that the mask portion 40 0 can stably cover the patient's mouth and nose in different postures, so there is no need for medical staff to hold the mask part 40 with their hands all the time; because the mandibular adjustment part 20 is arranged on the mandibular support frame main body 10, the adjustable part of the mandibular adjustment part 20 is located on the side of the mandibular support frame main body 10 close to the mandible, after the mandibular support frame main body 10 is sleeved on the patient's neck, the mandibular adjustment part 20 is located under the patient's mandible, and by adjusting the mandibular adjustment part 20, the adjustable part can be pressed against the patient's mandible to help the patient's mandible adjust to the best position, which is beneficial to the patient's breathing, so there is no need for medical staff to hold the patient's mandible all the time with their hands. Therefore, the adjustable mandibular support frame 100 provided in the present application is not only suitable for adjusting and fixing the patient's mandible and mask at the same time in some surgeries that require the patient to maintain a side-lying posture, but also does not require medical staff to hold the mask part 40 and the patient's mandible all the time with their hands, which can free the hands of medical staff.

[0079] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 4 The main body 10 of the mandibular support frame is provided with an internal airway through hole 111, and the mandibular adjustment part 20 includes an adjustment airbag 21 and an inflation and deflation device 22; wherein:

[0080] The adjustable part is the adjusting airbag 21 , which is adjustably arranged at one end of the mandibular support frame main body 10 facing the mandible, and the internal space of the adjusting airbag 21 is connected to one end of the internal airway through hole 111 .

[0081] The inflation and deflation device 22 is disposed on the main body 10 of the mandibular support frame, and the inflation and deflation device 22 is communicated with the other end of the internal airway through hole 111 .

[0082] Among them, the inflation and deflation device 22 is used to inflate the internal airway through hole 111 so that the regulating airbag 21 is inflated and expanded, so that the regulating airbag 21 can press against the patient's lower jaw to adjust and fix the angle of the lower jaw; the inflation and deflation device 22 is also used to perform an inhalation operation on the internal airway through hole 111 so that the regulating airbag 21 is deflated and contracted, so that the regulating airbag 21 can adjust and release the fixation operation on the lower jaw.

[0083] It can be understood that the regulating airbag 21 is an airbag used to adjust and fix the patient's mandibular angle. The inflation and deflation device 22 is a device used to inflate or deflate the internal airway through hole 111; the inflation and deflation device 22 can be an electric inflation pump or a manual inflation pump.

[0084] In this configuration, the inflation and deflation device 22 is used to inflate or deflate the adjusting airbag 21 through the internal airway hole 111, so that the adjusting airbag 21 expands or contracts toward the patient's lower jaw, thereby controlling the position of the patient's lower jaw; compared with the mechanical adjustment device, the adjusting airbag 21 of the above scheme can be more closely fitted to the patient's face, so as to increase the contact area between the adjusting airbag 21 and the patient's lower jaw, thereby reducing the damage to the patient during the adjustment and fixation of the lower jaw.

[0085] Optionally, in some embodiments, see Figure 1 and Figure 2 The mask adjustment part 30 includes a rotating adjustment member 31 and a moving adjustment member 32; wherein:

[0086] One end of the rotating adjustment member 31 is hinged to the side of the mandibular support frame main body 10 ; the other end of the rotating adjustment member 31 is provided with a moving guide groove 310 , and the guiding direction of the moving guide groove 310 is parallel to the length direction of the rotating adjustment member 31 .

[0087] One end of the movable adjustment member 32 is movably disposed in the movable guide groove 310 , and the other end of the movable adjustment member 32 is connected to the mask portion 40 .

[0088] It can be understood that the rotation adjustment member 31 is a member for adjusting the angle of the mask portion 40; for example, the rotation adjustment member 31 can be a rotation rod or a rotation housing, etc. The movement adjustment member 32 is a member for adjusting the position of the mask portion 40; for example, the movement adjustment member 32 can be a movement rod or a movement housing, etc.

[0089] In this arrangement, the mask part 40 is moved close to the patient's face by adjusting the movable adjustment member 32, and then the rotating adjustment member 31 is adjusted so that the mask part 40 can cover the patient's mouth and nose. Compared with the solution of sticking the mask part 40 to the patient's face with medical tape, the above solution can facilitate the adjustment of the mask part 40 at any time.

[0090] Optionally, see Figure 3 A plurality of fixed spaces 311 are provided on the side wall of the movable guide groove 310, and each fixed space 311 is arranged in sequence along the guide direction of the movable guide groove 310; the movable adjustment member 32 can be selectively moved into the fixed space 311 so that the mask part 40 can be fixed at the position corresponding to the fixed space 311.

[0091] In this way, by opening a plurality of fixed spaces 311 on the side wall of the movable guide groove 310, the movable adjusting member 32 is matched with one of the fixed spaces 311 to fix the movable adjusting member 32; compared with the externally arranged limiting member, this solution can simplify the fixing structure. And the rotating adjusting member 31 can be integrated to prevent the loss of the limiting member.

[0092] For example, see Figure 3 and Figure 4 The interior of the mandibular support frame main body 10 is provided with an internal airway branch hole 112 and a hinge hole 113, and the inner wall of the hinge hole 113 is circumferentially provided with a plurality of fixed matching holes 114, and the internal airway branch hole 112 is connected with the internal airway through hole 111; a conversion space 312 is opened inside the rotation adjustment member 31, and the conversion space 312 is connected with the internal airway branch hole 112; an installation through hole 313 is opened on the inner wall of the conversion space 312 near the hinge between the rotation adjustment member 31 and the mandibular support frame main body 10, and the position of the installation through hole 313 corresponds to the position of the fixed matching hole 114; the mask adjustment part 30 also includes a control airbag 35 and a fixing member 36; wherein:

[0093] The control airbag 35 is arranged in the internal airway branch hole 112, and the air inlet of the control airbag 35 is fixedly connected to the inner wall of the internal airway branch hole 112. The control airbag 35 extends into the conversion space 312, and the control airbag 35 is fixedly connected to the inner wall near the connection between the conversion space 312 and the internal airway branch hole 112.

[0094] The fixing member 36 is movably disposed in the mounting through hole 313 , and the fixing member 36 is located between the side wall of the control airbag 35 and the fixing matching hole 114 .

[0095] The control airbag 35 is used to expand and push the fixing member 36 to move toward one of the fixing matching holes 114 , so that the fixing member 36 partially extends into the fixing matching hole 114 , thereby limiting the rotation of the rotating adjustment member 31 .

[0096] It can be understood that the control airbag 35 is a component used to control the fixing member 36. The fixing member 36 is a component used to fix the rotation adjustment member 31; the fixing member 36 can be a cylindrical rod or a cylindrical shell.

[0097] In this way, the air inlet of the control airbag 35 is connected to the inner wall of the internal airway branch hole 112, and the inner side wall of the control airbag 35 near the connection between the conversion space 312 and the internal airway branch hole 112 is fixedly connected; so that the internal airway branch hole 112 and the control airbag 35 can maintain good sealing, and then the inflation and deflation device 22 can inflate and deflate the control airbag 35 through the internal airway branch hole 112, thereby pushing the fixing member 36 to partially extend into the fixing matching hole 114. Compared with the solution of separately setting a fixing device to fix the rotating adjustment member 31, this solution can simplify the device and reduce the manufacturing cost of the device.

[0098] In some embodiments, see Figure 3 , Figure 4 and Figure 7 One end of the fixing member 36 is connected to the side wall of the control airbag 35 , and the control airbag 35 is used to drive the fixing member 36 to move toward or away from the fixing matching hole 114 .

[0099] In this arrangement, by connecting one end of the fixing member 36 to the control airbag 35, the control airbag 35 can drive the fixing member 36 to move toward the fixing matching hole 114 or move away from the fixing matching hole 114. Compared with directly arranging the fixing member 36 between the control airbag 35 and the fixing matching hole 114, this solution can facilitate the fixing member 36 to move away from the fixing matching hole 114, thereby releasing the fixing of the rotating adjustment member 31.

[0128] The mandibular adjustment part 20 is adjusted so that the adjustable portion of the mandibular adjustment part 20 abuts against the mandibular portion of the patient.

[0129] As can be seen from the above, by placing the patient's neck in the neck wearing space 110, the chin support frame body 10 is fixed to the patient's neck by reducing the neck wearing space 110; so that the chin support frame body 10 can always be stably fixed to the patient's neck when the patient is in different postures. By adjusting the mask adjustment part 30, the mask part 40 can completely cover the patient's mouth and nose, and then the mask part 40 seals the gap between the mask part 40 and the patient's face. The chin adjustment part 20 is adjusted so that the adjustable part of the chin adjustment part 20 abuts against the patient's chin, and then the patient's chin is adjusted and fixed, thereby helping to assist breathing.
