Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a mandibular support. Background Art

[0002] In routine anesthesia clinics, emergency rooms, and intensive care unit work, clinicians often face jaw support, such as: 1. During the induction period of general anesthesia to preserve spontaneous breathing, when the respiratory depressant drugs take full effect, the patient's spontaneous breathing weakens and upper airway obstruction occurs. During this process, the anesthesiologist needs to support the patient's jaw. The anesthesiologist can complete the jaw support process by supporting the jaw with one hand or both hands. If the patient's head and face are too enlarged, the anesthesiologist needs another anesthesia nurse to perform bag-assisted ventilation while supporting the jaw with both hands, or the anesthesiologist needs to perform mechanical ventilation while supporting the jaw with both hands to ensure adequate oxygen supply and ventilation. 2. During the recovery period of anesthesia extubation, patients are prone to respiratory depression and upper airway obstruction due to the residual effects of anesthetics and muscle relaxants. The anesthesiologist needs to support the patient's jaw to ensure a clear upper airway. 3. In the emergency department and intensive care unit, patients who are mechanically ventilated with a ventilator are prone to partial respiratory depression, upper airway obstruction, restlessness and intubation intolerance, accidental extubation, etc. in the state of consciousness or confusion due to their condition, the use of sedatives and analgesics, residual muscle relaxants, etc., and may need to be re-intubated and assisted with jaw support ventilation after evaluation.

[0003] In order to solve this problem, the prior art mainly uses a mandibular support device to assist medical staff to solve the above problem. For example, Chinese utility patent CN216725124U discloses a semi-fixed mandibular support device. It includes a support structure and a support assembly; the support structure includes a relatively arranged base, the support mechanism includes a support pad body located above the base, and a lifting mechanism fixed to the upper end of the base for adjusting the height of the support pad body is provided below the support pad body, and a mounting sleeve is provided at the upper end of the lifting mechanism, and the mounting sleeve is rotatably matched with the support pad body. The support structure in the utility model can move relatively and adjust the position and stability of the base as needed. The patient can support his mandible through the support assembly. The utility model can replace the medical staff to support the patient's mandible with their hands, freeing the hands of doctors and medical staff, which is conducive to better intraoperative anesthesia management.

[0004] Regarding the above-mentioned related technologies, when it is necessary to lift the patient's mandible, the main operation is to operate the support pad body to move up and down and use the support pad body to rotate from bottom to top to support the human mandible. However, during operation, it is necessary to adjust the lifting cylinder and the adjusting mounting screws separately, which will cause inconvenience in operation. Utility Model Content

[0080] Considering that the existing mandibular lifting equipment is inconvenient for medical staff to operate when lifting patients, the present application provides a mandibular support frame, which can improve the convenience of operation for medical staff and contribute to the application and promotion of mandibular lifting equipment.

[0081] Specifically, the present application embodiment discloses a mandibular bracket, referring to Figure 1 The mandibular support of the present application can be used to lift the patient's head to a suitable angle to assist the patient's ventilation. Figure 2 and Figure 3 The mandibular support comprises a support arm 10, a rotating member 20, a lifting member 30, a first locking mechanism 40 and a first release button 50. The support arm 10 can be extended and retracted in the height direction, and the rotating member 20 is rotatably connected to the support arm 10 around a horizontal line.

[0082] Reference Figure 3 In one embodiment, a hollow shaft 101 is disposed at the center of the end surface of the support arm 10, a hole groove matching the hollow shaft 101 is opened at the center of the rotating member 20, and the rotating member 20 is rotatably connected to the support arm 10 through the hollow shaft 101. In another embodiment, the hollow shaft 101 can also be disposed on the rotating member 20, in which case a hollow groove matching the hollow shaft 101 is opened at the center of the support arm 10.

[0083] Reference Figure 3 and Figure 4 A mounting cylinder 210 is provided on the side of the rotating member 20 deviating from its own center, and the supporting member 30 includes a connecting rod 31 and a supporting block 32. One end of the connecting rod 31 is detachably connected to the mounting cylinder 210, and the supporting block 32 is fixed to the end of the connecting rod 31 away from the mounting cylinder 210.

[0084] In one embodiment, a mounting hole 211 is provided in the mounting cylinder 210, and one end of the connecting rod 31 is inserted into the mounting hole 211. The connecting rod 31 and the mounting hole 211 may be interference fit or clearance fit. In another embodiment, a damping pin 310 may be provided on the outer wall of the connecting rod 31 or the inner wall of the mounting hole 211, and damping locking is achieved by the damping pin 310. The connecting rod 31 may also be threadedly connected to the mounting cylinder 210.

[0085] In order to prevent the connecting rod 31 from rotating in the mounting hole 211, the cross-section of the mounting hole 211 in the embodiment of the present application is semicircular. In other embodiments, the cross-section of the mounting hole 211 can be triangular, diamond or irregular, etc., as long as the connecting rod 31 is not prone to rotating when installed in the mounting hole 211.

[0086] In a preferred embodiment, the connecting rod 31 extends along the horizontal direction and extends in the direction close to the human face, and the support block 32 is fixed to the end of the connecting rod 31 away from the rotating member 20. At this time, the support block 32 is equivalent to the support arm 10 being closer to the human face, so that when the mandibular support is performed, the support arm 10 can reduce the obstruction to the movement of the human head, and it is more conducive to medical staff to observe the position of the mandibular angle of the human body, thereby improving the convenience of operation for medical staff.

[0087] Reference Figure 4 In one embodiment, the support surface of the support block 32 is detachably mounted with a support pad 33, and the support block 32 and the support pad 33 can be connected by bonding or snap connection. The support block 32 can be a structure with a central groove or a structure without a groove, and the support pad 33 is made of a flexible material to make it more comfortable when fitting the mandibular angle of the human body.

[0088] Reference Figure 3 , the first locking mechanism 40 is used to lock the support arm 10 and the rotating member 20 at a preset position; and

[0089] When the first release button 50 is triggered, the locking of the support arm 10 and the rotating member 20 by the first locking mechanism 40 can be released simultaneously.

[0090] Reference Figure 3 and Figure 5 In one embodiment, the first locking mechanism 40 includes a rotation locking assembly 41 and a height locking assembly 42. The rotation locking assembly 41 can lock the clockwise or counterclockwise rotation of the rotating member 20, and the height locking assembly 42 can lock the extension and retraction of the support arm 10 from top to bottom.

[0091] In one embodiment, the rotating member 20 is a circular hollow shell, which is detachably connected to a shell end cover 220. The first release button 50 is slidably connected to the rotating member 20 along the radial direction of the rotating member 20, and the pressing end of the first release button 50 is placed on the outside of the rotating member 20 for easy pressing by personnel.

[0092] In one embodiment, the rotation angle of the rotating member 20 is between 20° and 100°. The purpose of this design is that, on the one hand, a large rotation angle is not required during actual use, and on the other hand, it is conducive to the rapid reset of the rotating member 20. At this time, a corresponding limit portion will be designed between the rotating member 20 and the support arm 10 to limit the angle. The specific structure can be designed according to the means of those skilled in the art.

[0093] Refer to 3 and Figure 5The rotation locking assembly 41 includes an end face ratchet 410, a rotation pawl 411 and a rotation transmission assembly.

The two ends of the rotation pawl 411 are respectively placed on the outside of the guide square groove 230. One end of the rotation pawl 411 extends out of the rotating member 20 and is engaged with the end face ratchet 410. The end face ratchet 410 can stop the rotation of the rotation pawl 411 clockwise or counterclockwise around the central axis.

[0094] Among them, the rotary transmission assembly includes a first wedge-shaped boss 412, a second wedge-shaped boss 413 and a rotary pawl resetting member. The first wedge-shaped boss 412 is arranged on the side wall of the first release button 50, and the second wedge-shaped boss 413 is arranged at one end of the rotary pawl 411 located in the rotary member 20. The first wedge-shaped boss 412 can slide and abut against the wedge surface of the second wedge-shaped boss 413.

[0095] When the first release button 50 is pressed and moves into the rotating member 20, the first wedge-shaped boss 412 pushes the second wedge-shaped boss 413 to move, so that the rotating pawl 411 moves away from the end face ratchet 410, thereby achieving unlocking. When the first release button 50 is released, the rotating pawl 411 moves close to the end face ratchet 410 under the action of the rotating pawl reset member, thereby achieving locking.

[0096] Reference Figure 5 and Figure 6 In one embodiment, the rotary pawl reset member is a rubber band (not shown in the figure), the side wall of the rotary pawl 411 is provided with a rubber band stopper 414, and the inner side of the rotary member 20 is provided with a rubber band hook 415, the two ends of the rubber band are connected by the rubber band hook 415, and the rubber band is used to press the rubber band stopper 414, so as to achieve reset.

The third wedge-shaped boss 422 can push the height pawl push rod 423 to move axially so that the height pawl push rod 423 pushes the height pawl 421 away from the height ratchet 420, so as to separate the height pawl 421 from the height ratchet 420 to achieve unlocking.

[0103] At this time, the height pawl resetting member (not shown in the figure) can be a spring, a torsion spring, a rubber band, etc., which can drive the height pawl 421 to approach the height ratchet 420.

[0104] In one embodiment, the first wedge-shaped boss 412 and the third wedge-shaped boss 422 are at different height positions. When the first release button 50 is pressed, the unlocking in the rotational direction may be triggered first, and then the unlocking in the height direction and the rotational direction may be triggered simultaneously; or the unlocking in the height direction may be triggered first, and then the unlocking in the rotational direction and the height direction may be triggered simultaneously.
