[0035] like Figure 1-8 As shown, an embodiment of the present invention provides: a device for preventing breath holding during bronchoscopic general anesthesia examination, comprising a shoulder limiter 1 and a head limiter 2, specifically,

[0036] The shoulder limiter includes a bottom plate 3, a support plate 4 and a lifting assembly, and the head limiter includes a head plate 5. A clamping clamp 6 is arranged on each of the left and right sides of the head plate. One end of the head plate is rotatably connected to the support plate, and the other end is in a free state. Therefore, when the height of one end of the head plate changes, the adjustment of the head angle is achieved. A lower jaw lifting mechanism 7 is respectively arranged on the two clamping clamps, that is, a lower jaw lifting mechanism is arranged on one clamping clamp, so as to realize the lifting of the lower jaws on both sides of the patient to achieve balance. The clamping clamp includes a support arm 8 and a flexible clamping palm 9. Sponge or silicone is arranged on the flexible clamping palm, so that it has better compliance, is more fit and comfortable to contact with the human head, and achieves a better limiting effect.

[0037] The mandibular lifting mechanism of this embodiment includes a fixed plate 10, an adjusting screw 11, a movable plate 12 and a lifting finger 13. The fixed plate is fixed on the support arm, and a threaded hole matching the adjusting screw thread is provided in the middle area of ​​the fixed plate. One end of the adjusting screw passes through the threaded hole to act on the movable plate, so that the movable plate moves relative to the fixed plate. A lifting knob 34 is provided at the other end of the adjusting screw. A reset spring (not shown) is provided between the movable plate and the fixed plate. The lifting finger includes a flexible rod 14 and a flexible finger 15. One end of the flexible rod is fixed to the movable plate, and the other end is fixed to the flexible finger. When the adjusting screw rotates forward, the screw extends out and abuts against the movable plate, and the movable plate moves forward, thereby driving the lifting finger to move forward. When it is close to the human jaw, the flexible finger first contacts the human body. Since the flexible finger is soft and has good fit, it will not cause discomfort to the human body. With further rotation, the lifting finger continues to move, thereby further increasing the contact force. When a certain force is reached, the operation is stopped, so that the lifting finger is continuously and stably on the human jaw, thereby replacing manual operation.

[0038] The lifting assembly of this embodiment includes two lifting mechanisms 16 arranged at intervals in front and back. Due to the interval arrangement in front and back, different heights can be adjusted by the two lifting mechanisms to achieve different slopes relative to the head or bed surface, to achieve an angle matching the patient, and to be fully applicable to all different patients.

[0039] In this embodiment, a rotating shaft 17 is provided at the free end of the head plate, and a rotating sleeve 18 is rotatably provided on the rotating shaft. The rotating sleeve is connected to a parallel support plate 19, and the contact with the bed surface is achieved through the parallel support plate, so as to avoid direct contact between the head plate and the bed surface to cause extrusion or damage, and also facilitate the horizontal movement of the head plate.

[0040] In this embodiment, the two lifting mechanisms have the same structure and both include two connecting rod groups arranged in a V shape and a lifting operating rod 20 connected between the two connecting rod groups. The V-shaped large ends of the two connecting rod groups are arranged opposite to each other. The connecting rod group includes two upper connecting rods 21 hinged to the support plate and two lower connecting rods 22 hinged to the bottom plate. The two upper connecting rods are arranged one-to-one with the two lower connecting rods, that is, one upper connecting rod corresponds to a lower connecting rod, and the upper and lower are hinged to each other and connected by a rotating shaft. Two groups are formed between the two upper and lower parts. A connecting plate 23 is arranged in the area between the two groups of hinges. A threaded hole is arranged on the connecting plate, and the threaded holes on the two connecting plates rotate in opposite directions. An external thread matching the two threaded holes is arranged on the lifting operating rod, and the lifting operating rod is inserted into the threaded hole. A height adjustment button 24 is arranged at the front end of the lifting operating rod, and a locking nut 25 is arranged at the rear end. When the lifting operating rod is rotated, the two connecting plates approach or move away from each other, so that the upper and lower connecting rod groups rotate at the rotating shaft to achieve height adjustment.

[0041] Furthermore, a connecting seat 26 is provided on both the support plate and the bottom plate, a connecting shaft 27 is provided on the connecting seat, and the other end of the upper connecting rod or the lower connecting rod is connected to the connecting shaft, thereby realizing a hinged connection.

[0042] Further, one of the two clamps is fixedly and detachably connected to the head plate, such as threaded fixing, and the other clamp is movably connected to the head plate. The movable connection is not limited. The movable connection of this embodiment includes a movable seat 28 and a fixed seat 29. A slide bar is provided on the movable seat, and a slide groove matching the slide bar is provided on the head plate. A push rod 30 is threadedly connected to the fixed seat, one end of the push rod is in contact with the movable seat, and the other end is provided with a push knob 31. When it is found that the two clamps cannot clamp the human head normally, the push knob is rotated to extend the push rod, thereby pushing the movable seat to move, so that the clamp is close to the patient's head and further extended. After the clamping force is reliable and stable, the operation is stopped.

[0043] In this embodiment, a flexible sealing cover 32 is provided between the bottom plate and the support plate, thereby protecting the moving parts from contamination and improving the aesthetics.

[0044] In this embodiment, the support plate is provided with an arc groove 33. The arc groove has an arc shape adapted to the human body, thereby improving the comfort of lying down.

[0045] In this embodiment, a connecting shaft is provided between the head plate and the support plate to achieve a rotational connection.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
