[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides an anesthesia auxiliary stent for anesthesia, which has the following beneficial effects:

[0021] 1. In the present invention, the first joint bracket, the second joint bracket and the drooping bracket are rotatably connected together through a rotating connection assembly, and can be adjusted according to the patient's position, so that the anesthesia mask installed on the drooping bracket can be aligned with the patient's respiratory part, thereby achieving support for the anesthesia mask. When adjusting the position of the anesthesia mask, the drooping bracket and the second joint bracket are in a loose rotational connection state. Therefore, when the anesthesia mask is adjusted, the drooping bracket is always vertically downward, and there is no need to adjust the drooping bracket after adjusting the angles of the first joint bracket and the second joint bracket, thereby improving the efficiency of bracket adjustment.

[0022] 2. The present invention is provided with a pipe restraining mechanism on one side of the first joint bracket and the second joint bracket. The pipe restraining mechanism is in a semi-open state in the initial state, so that after the anesthesia tube is placed in the pipe restraining mechanism, the anesthesia tube cannot fall out of it under its own weight. After the rotating rod assembly is rotated, the first restraining plate and the second restraining plate are closed, and the original semi-open state is closed by matching the anti-drop buckle and the plug-in notch, so that the anesthesia tube cannot fall off under the action of artificial pulling, and the closed pipe restraining mechanism will not cause the anesthesia tube to be deformed along the axial direction of the pipe, and will only bend at the threaded part, and such bending can be repaired artificially. If the threaded pipe is pulled, squeezed and deformed along its axial direction, the thread will be deformed and it will be difficult to repair artificially.

[0023] 3. When the anesthesia mask is adjusted to a good position and the anesthesia tube is initially engaged in the half-opened pipe restraining mechanism, the loose drooping bracket is locked by rotating the threaded sleeve to prevent the anesthesia mask from shaking during surgery. At the same time, the rotation of the threaded sleeve will drive the pull rope to rotate, thereby driving the rotating rod assembly to rotate, so that the half-opened pipe restraining mechanism is completely closed, and the drive block is driven to move, so that the rotating connection parts of the rotating ear, the first joint bracket and the second joint bracket are locked, so as to avoid accidental adjustment during surgery, which may cause the anesthesia mask to be out of the position for the patient to breathe anesthesia.

[0037] For examples, see Figure 1 - Fig. 9, an anesthesia auxiliary support for anesthesia, including a multi-joint support mechanism 1, which includes a fixed component 2, and also includes a multi-joint support component 3 rotatably mounted on the fixed component 2, and a rotating connection component 4 arranged on the multi-joint support component 3, a pipeline restraining mechanism 5, which includes a restraining component 6 arranged on the multi-joint support component 3, and a rotating rod component 7 for driving the restraining component 6 to open and close, a driving mechanism 8, which includes a winding and locking component 9 arranged on the multi-joint support component 3, and also includes a pull rope 10 connecting the rotating rod component 7 and the rotating connection component 4, the multi-joint support component 3 includes a first joint support 301 rotatably mounted on the fixed component 2, and also includes a second joint support 3 rotatably connected to the first joint support 301 at one end away from the fixed component 2 02, and a drooping bracket 303 rotatably connected to the second joint bracket 302 at one end away from the first joint bracket 301, the first joint bracket 301 and the second joint bracket 302 are symmetrically provided with a first movable cavity 304 and a second movable cavity 305, the drooping bracket 303 is provided with an elastic clamp 306, the restraining assembly 6 includes a first restraining plate 601 rotatably installed in the first movable cavity 304, and also includes a second restraining plate 602 rotatably installed in the second movable cavity 305, the first restraining plate 601 and the second restraining plate 602 are both provided with a limiting slide groove 603, and the limiting slide groove 603 and the rotating rod assembly 7 are matched and connected, the limiting slide groove 603 is provided with a first spring 604, and the first spring 604 and the rotating rod assembly 7 are in conflict.

[0038] The fixing assembly 2 includes a rotating ear 201 rotatably connected to one end of the first joint bracket 301 , a U-shaped seat 202 integrally formed with the rotating ear 201 , and a fixing bolt 203 disposed on the U-shaped seat 202 .

[0039] In this embodiment, the U-shaped seat 202 is clamped on the bed frame on the operating bed and then locked and fixed by the fixing bolt 203. The first joint bracket 301 and the rotating ear 201 are connected by the rotating connection component 4. The second joint bracket 302 and the end of the first joint bracket 301 away from the rotating ear 201 are connected by the rotating connection component 4. The drooping bracket 303 and the end of the second joint bracket 302 away from the first joint bracket 301 are rotatably connected.

[0040] In the initial state, the retracting locking assembly 9 is not locked, so that the drooping bracket 303 and the second joint bracket 302 are arranged to rotate smoothly, that is, no matter how the rotating ear 201, the first joint bracket 301 and the second joint bracket 302 are adjusted, the drooping bracket 303 is vertically downward, and the axial direction of the length direction of the drooping bracket 303 will not change due to the adjustment of the second joint bracket 302. Therefore, after the rotating ear 201, the first joint bracket 301 and the second joint bracket 302 are adjusted, the vertical position of the drooping bracket 303 is the position where the anesthesia mask is placed, and the anesthesia mask is fixed by the elastic clamp 306.

[0041] Furthermore, when the retracting locking assembly 9 is not locked, under the push of the first spring 604, the rotating rod assembly 7 is rotated and tilted, and the angle between the first restraint plate 601 and the second restraint plate 602 is an acute angle. In this state, the rotating rod assembly 7 pulls one end of the first restraint plate 601 and the second restraint plate 602, so that the other end of the first restraint plate 601 and the second restraint plate 602 is half-open, and the end of the inclined rotating rod assembly 7 is located in the middle position of the limiting slide groove 603, so that the half-opened first restraint plate 601 and the second restraint plate 602 can be further expanded under human operation, thereby facilitating the placement of the anesthesia tube in the middle of the first restraint plate 601 and the second restraint plate 602 for preliminary limiting fixation.

[0042] It should be noted that in order to allow the half-opened first binding plate 601 and the second binding plate 602 to be expanded manually, the pull rope 10 connected between the rotating rod assembly 7 near the retracting and locking assembly 9 on the second joint bracket 302 needs to be in a relaxed state, so as to provide a displacement amount for the rotating rod assembly 7 to drive the pull rope 10 when the first binding plate 601 and the second binding plate 602 are expanded manually. The first movable cavity 304 has first rotating shaft holes 307 at both ends for rotatably mounting the first binding plate 601, and a second spring 308 is provided in the first rotating shaft hole 307 at one end of the first movable cavity 304;

[0043] The second movable cavity 305 has second rotation shaft holes 309 at both ends for rotatably mounting the second binding plate 602 , and a third spring 310 is disposed in the second rotation shaft hole 309 at one end of the second movable cavity 305 away from the second spring 308 .

[0044] The first restraint plate 601 and one end of the second restraint plate 602 are matched by rotating and fitting, and the first restraint plate 601 and the second restraint plate 602 are provided with anti-drop buckles 605 on the opposite ends, and the first restraint plate 601 and the second restraint plate 602 are provided with plug-in notches 606 on the ends away from the anti-drop buckles 605, and the plug-in notches 606 and the anti-drop buckles 605 match.

[0045] The rotary rod assembly 7 includes a rotary shaft 701 rotatably mounted on the first joint bracket 301 and the second joint bracket 302 , a rotary rod 702 symmetrically arranged on the rotary shaft 701 , and a ball head 703 arranged on the rotary rod 702 .

[0046] In this embodiment, the second spring 308 and the third spring 310 are respectively set at the opposite ends of the first binding plate 601 and the second binding plate 602 to each other. Under the push of the second spring 308 and the third spring 310, the first binding plate 601 and the second binding plate 602 in the initial state are staggered along their length direction. When the pull rope 10 pulls the rotating rod assembly 7 to rotate, the angle between the rotating rod assembly 7 and the first binding plate 601 and the second binding plate 602 changes from an acute angle to a vertical angle as the rotating rod 702 rotates. When it moves to be perpendicular to the first restraint plate 601 and the second restraint plate 602, the half-open ends of the first restraint plate 601 and the second restraint plate 602 are fitted together and closed, and the ball head 703 on the rotary rod 702 contacts one end of the limiting slide groove 603. At this time, the pull rope 10 continues to pull to drive the rotary rod 702 to continue to rotate, pushing the misaligned first restraint plate 601 and the second restraint plate 602 to move toward the correct position, so that the anti-drop buckle 605 on the first restraint plate 601 and the plug-in notch 606 on the second restraint plate 602 are matched and plugged in.

[0047] It should be noted that when the first restraint plate 601 and the second restraint plate 602 move toward the normal position, the rotating rod 702 is no longer perpendicular to the first restraint plate 601 and the second restraint plate 602, so that the first restraint plate 601 and the second restraint plate 602 will move away from each other at the fitting ends, but the gap is smaller than the height of the anti-drop buckle 605.

[0048] The rotating connection component 4 includes a connecting shaft 401 arranged at both ends of the first joint bracket 301, a gear 402 arranged on the connecting shaft 401, and also includes an anti-slip block 403 welded to the gear 402, and a driving block 404 fixedly connected to the pull rope 10. The rotating ear 201 and the second joint bracket 302 are both provided with a through hole at one end corresponding to the rotating connection component 4, and the through hole and the connecting shaft 401 are matched and plugged.

[0049] The driving block 404 is provided with a moving cavity 405 , and a spring groove 406 is provided on one side of the moving cavity 405 . A fourth spring 407 and a latching tooth 408 are disposed inside the spring groove 406 , and the latching tooth 408 is engaged with the tooth groove of the gear 402 .

[0050] The rotating ear 201 and the second joint bracket 302 are both provided with limit bars 409 , and the limit bars 409 are matched and provided on both sides of the driving block 404 .

[0051] In this embodiment, in the initial state, under the action of the fourth spring 407, the latch 408 and the tooth groove of the gear 402 are engaged, and the driving block 404 slides along the direction of the limit strip 409. Therefore, when the rotating ear 201, the first joint bracket 301 and the second joint bracket 302 are rotated and adjusted, preliminary angle locking can be performed by engaging the latch 408 and the tooth groove of the gear 402.

[0052] The winding and locking assembly 9 includes a screw rod 901 arranged at one end of the second joint bracket 302 away from the first joint bracket 301, a threaded sleeve 902 threadedly locked with the screw rod 901, and a retaining ring 903 arranged at one end of the threaded sleeve 902. A through hole is opened on the drooping bracket 303, and the through hole and the screw rod 901 are plugged and matched.

[0053] The threaded sleeve 902 is fixedly connected to one end of the pull rope 10 , and two pull ropes 10 are provided. The two pull ropes 10 are connected in series in sequence to the rotary rod 702 and the driving block 404 on the first joint bracket 301 and the second joint bracket 302 .

[0054] In this embodiment, after the angle position adjustment of the multi-joint support assembly 3 is determined and the anesthesia mask is located at the patient's breathing position, the threaded sleeve 902 is rotated, and the threaded sleeve 902 and the screw 901 are threadedly locked, so that the silky rotating drooping support 303 and the second joint support 302 are fixed and locked. At the same time, the locking rotation of the threaded sleeve 902 reels the hand pull rope 10, thereby pulling the pull rope 10, so that the rotating rod assembly 7 connected to the pull rope 10 rotates, driving the half-opened first binding plate 601 and the second binding plate 602 to fit and close, and driving the drive block 404 to move along the limit strip 409, so that the fourth spring 407 is compressed, so that the locking tooth 408 and the gear 402 are completely stuck and cannot rotate, thereby locking the rotating part of the multi-joint support assembly 3.

[0055] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, welding is preferred for all fixed connections. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
