DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] The embodiments of the present application are further described below with reference to the drawings.

[0038] Reference Figures 1-10 The embodiment provides a tracheal cannula fixing device with gear self-locking, comprising:

[0039] A fixing support 1 is provided with a plurality of first clamping positions 11 and a plurality of first clamping teeth 13 in the left-right direction;

[0040] A fixing knob 2 is provided with a second clamping position 21 for forming a clamping relationship with one of the first clamping positions 11;

[0041] A moving gear 3 is partially arranged in the fixing support 1, and the moving gear 3 is provided with a second clamping tooth 31 for forming a clamping relationship with one of the first clamping teeth 13;

[0042] A moving support 4 is arranged on the lower side of the fixing support 1, and the moving support 4 is formed with a fixing groove 41 for passing and fixing the tracheal cannula;

[0043] One end of the fixing knob 2 is fixedly connected with the moving support 4 after passing through the fixing support 1 and the moving gear 3.

[0044] As Figure 6 The fixing support 1 is provided with two guide rails 12 arranged in the left-right direction, and the moving gear 3 is arranged between the two guide rails 12.

[0045] When the fixing position of the tracheal cannula needs to be adjusted, the nursing staff pushes the moving gear 3 to the left or the right, the second clamping tooth 31 of the moving gear 3 is disengaged from the first clamping tooth 13 currently in the clamping relationship, and the moving gear 3 pushes the moving support 4 and the fixing knob 2 to move left and right during rotation. The fixing knob 2 can rotate relative to the moving gear 3, such as Figure 5 And Figure 10 After moving the moving support 4 to the specified position according to actual needs, the fixing knob 2 is pushed to rotate the second clamping position 21 of the fixing knob 2, and when the second clamping position 21 is rotated to be buckled with the first clamping position 11 of the fixing support 1, since the position of the fixing knob 2 is fixed, this prevents the moving support 4 from continuing to slide, so that the fixing of the moving support 4 is realized. The tracheal cannula fixing device solves the problem that the left-right position of the tracheal cannula cannot be adjusted after the tracheal cannula is fixed in the prior art; meanwhile, since the tracheal cannula inserted in the fixing groove of the moving support 4 can be moved left and right as required, when the oral cavity of the patient is cleaned, the sputum can be cleaned, hygienically maintained and the cleanable range can be expanded from multiple positions.

[0046] As Figure 6 The fixing support 1 is provided with two guide rails 12 arranged in the left-right direction, and the moving gear 3 is arranged between the two guide rails 12.

[0047] The guide rail 12 is 2, 2 guide rail 12 parallel arrangement, 2 guide rail 12 between the gap for a part of the moving gear 3 inserted.

[0048] As Figure 8 , the fixed groove 41 is provided with the upper extrusion rib 42 and the lower extrusion rib 43 for extruding and fixing the tracheal tube.

[0049] In the tracheal tube fixing, the tracheal tube is directly inserted from the left side opening of the fixed groove 41 of the moving bracket 4, and is placed between the upper extrusion rib 42 and the lower extrusion rib 43 of the moving bracket 4. The tracheal tube is limited by the lower extrusion rib 43 of the moving bracket 4, and the tracheal tube is fixed and moved by the upper extrusion rib 42 and the lower extrusion rib 43. The overall structure is simple and reliable, low in cost, and can greatly reduce the time of fixing the tracheal tube.

[0050] Referring to Figure 1 and Figure 2 , the tracheal tube fixator further comprises:

[0051] Sponge pad 5, the sponge pad 5 is fixed on the fixed bracket 1, and is arranged towards the patient's face. The sponge pad 5 is used to contact the upper part of the patient's nose, and provides comfort for the patient; prevent the use of mouthpiece for a long time, causing pressure ulcer.

[0052] Referring to Figure 1 and Figure 2 , the tracheal tube fixator further comprises:

[0053] Silicone paste 6, the silicone paste 6 is fixed on both ends of the fixed bracket 1, and is arranged towards the patient's face;

[0054] The sponge pad 5 is arranged between the two pieces of silicone paste 6 and is arranged towards the patient's nose.

[0055] In use, the silicone paste 6 is pasted on both sides of the patient's face, which assists in fixing the tracheal tube fixator and provides comfort.

[0056] Referring to Figure 1 and Figure 2 , the tracheal tube fixator further comprises:

[0057] Headband 7, the headband 7 is fixed on both ends of the fixed bracket 1. The headband 7 is threaded through the headband 7 fixing ring on the left and right sides of the fixed bracket 1 and is fixed by sewing. The headband 7 on both sides is wrapped around the patient's head and is fixed by adhesion, thereby assisting in fixing the tracheal tube fixator.

[0058] Referring to Figures 8-10The mobile support 4 is provided with a buckle hole 44, and the fixed knob 2 is provided with a connecting buckle 22 which is buckled into the buckle hole 44.

[0059] With reference to Figure 6 The fixed support 1 is further provided with displacement-preventing lower edges 14 on the left and right sides for limiting the position of the mobile support 4. The two displacement-preventing lower edges 14 are arranged on the left and right sides of the mobile support 4 to limit the left and right moving positions of the mobile support 4.
