[0034] The following will detail the embodiments of the present utility model with reference to the drawings.

[0035] Embodiment:

[0036] See Figure 1 and Figure 2 , a fixing device for the pipeline of a ventilator, including a bracket 1, a support rod 2, a connecting pipe 3, a hinge rod 4, and a positioning bolt 5. Specifically, the bracket 1 is an L-shaped structure. One end of the bracket 1 is a support end 6, and the other end of the bracket 1 is a connecting end 7. The connecting end 7 of the bracket 1 is used to connect the cabinet for placing the non-invasive ventilator, and the connecting end 7 of the bracket 1 is in the vertical direction, so that the support end 6 of the bracket 1 is in the horizontal direction.

[0037] One end of the support rod 2 is rotatably connected to the support end 6 of the bracket 1. Under the action of natural gravity, the support rod 2 is in a vertically downward state. Two support rods 2 are provided on the support end 6 of the bracket 1, and the two support rods 2 are symmetrically distributed.

[0038] Two articulated rods 4 are respectively arranged on the two support rods 2. One end of the articulated rod 4 is rotatably connected to the middle of the support rod 2. The ends of the two articulated rods 4 away from the support rod 2 are hinged to each other, so that the two articulated rods 4 and the two support rods 2 form a movable quadrilateral structure.

[0039] A positioning bolt 5 is arranged at the hinge of the two articulated rods 4. Through the positioning bolt 5, the included angle between the two articulated rods 4 can be locked, and the included angle between the two support rods 2 can be fixed.

[0040] Two connecting pipes 3 are respectively rotatably arranged at the ends of the two support rods 2 away from the support end 6 of the bracket 1. The side wall of the connecting pipe 3 is connected to the support rod 2. The middle of the connecting pipe 3 is a hollow circular structure, and the center lines of the two connecting pipes 3 are collinear.

[0041] The working principle of this embodiment is to set the bracket 1 and connect and install the bracket 1 on the cabinet for placing the non-invasive ventilator through the connecting end 7 of the bracket 1. Two support rods 2 are arranged on the support end 6 of the L-shaped bracket 1, and connecting pipes 3 are arranged at the ends of the support rods 2. During use, the pipeline of the non-invasive ventilator is passed through the two connecting pipes 3, and then the two support rods 2 are driven to rotate by the two articulated rods 4 to adjust the included angle between the two support rods 2, so as to realize the support of multiple points of the pipeline. In this embodiment, by arranging multiple connecting pipes 3 to support the pipeline, the phenomenon that the pipeline is bent due to its high flexibility is avoided.

[0042] In one specific embodiment:

[0043] The fixing device further includes a movable rod 8 and a locking bolt 9. The movable rod 8 is slidably arranged on the support end 6 of the bracket 1 and can slide along the length direction of the support end 6. The locking bolt 9 is arranged on the movable rod 8, and the end of the locking bolt 9 can abut against the support end 6 of the bracket 1.

[0044] Preferably, the movable rod 8 is a tubular structure, and the movable rod 8 is sleeved on the support end 6 of the bracket 1. A limiting strip is arranged on the inner wall of the movable rod 8 along its length direction, and a limiting groove 10 corresponding to the limiting strip is arranged on the support end 6 of the bracket 1. The end of the above-mentioned support rod 2 is rotatably connected to the end of the movable rod 8 away from the support end 6 of the bracket 1.

[0045] In this embodiment, by providing the movable rod 8, the support rod 2 can move along the length direction of the support end 6, so as to adapt to the use of the non-invasive ventilator at different positions.

[0046] In another specific embodiment:

[0047] The fixing device further includes a support plate 11, a connecting rod 12 and a sleeve 13. Among them, the top of the support plate 11 is fixedly arranged at one end of the movable rod 8 away from the support end 6. The support plate 11 is located below the movable rod 8, and two round chamfers are respectively arranged at both ends of the bottom of the support plate 11. The end parts of the two support rods 2 are respectively rotatably connected to the two round chamfers of the support plate 11.

[0048] A connecting rod 12 is arranged in the middle of the support plate 11. The connecting rod 12 is arranged vertically downward, and a sleeve 13 is sleeved on the connecting rod 12. A connecting pipe 3 is also arranged at one end of the sleeve 13 away from the connecting rod 12.

[0049] In addition, the two ends of the top of the sleeve 13 are respectively rotatably connected to the end parts of the two hinge rods 4, and the end part of the locking bolt 9 passes through a hinge rod 4 and the sleeve 13 and can abut against the connecting rod 12.

[0050] When the included angle between the two hinge rods 4 is equal to 180°, the included angle between the two support rods 2 is less than or equal to 120°, and at this time, the connecting rod 12 is completely located inside the sleeve 13.

[0051] In this embodiment, by providing the connecting rod 12, a point for supporting the pipeline can be added in the fixing device. In addition, by providing the sleeve 13, while driving the two support rods 2 to move, the sleeve 13 can be driven to move on the connecting rod 12, so that the three connecting pipes 3 can move up or down simultaneously, thereby reducing the probability of pipeline bending.

[0052] The above embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
