Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the adjustable tracheal intubation of particularly a kind of curvature.
Background technology
Tracheal intubation of the prior art is widely used in clinically, and like esophagectasia, the respirator spoke helps breathing, and the domestic patent of this respect can be referring to following utility model: 86201035; 86209325,87201619,2031682,2046017; 2050763,2052280,2059590,2060355; 2066734,2066744,2084379.All above disclosed tracheal intubatioies of patent all can not be regulated the curvature of its intubate voluntarily.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of this invention is to provide the adjustable tracheal intubation of a kind of curvature, have easy to use, simple in structure and can regulate the advantage of its intubate curvature voluntarily.
For reaching above-mentioned purpose, technical scheme of the present invention is following:
The adjustable tracheal intubation of a kind of curvature comprises the air bag on tracheal intubation, the tracheal intubation, also further comprises tracheal intubation joint and tracheal intubation curvature adjusting device; Tracheal intubation curvature adjusting device includes regulating shaft, regulating handle, adjusting steel wire, regulates silk thread; The tracheal intubation joint is fixedly connected tracheal intubation down, and top connects tracheal intubation curvature adjusting device; Regulate an end of silk thread and fix with the end of regulating steel wire, one is fixed on the terminal inwall of tracheal intubation, and the other end links to each other with regulating shaft.
That the present invention has is simple in structure, tightly play, rationally, characteristics such as easy to use, and in medical procedure, can reduce medical time of healthcare givers widely, the present invention can replace existing tracheal intubation at large, is widely used clinically.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is an another kind of structural representation of the present invention.
Fig. 3 is the structural representation of regulating shaft of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
Shown in Fig. 1-3, the adjustable tracheal intubation of a kind of curvature is made up of the air bag on tracheal intubation 1, the tracheal intubation 2, tracheal intubation joint 3 and tracheal intubation curvature adjusting device 4 etc.Tracheal intubation curvature adjusting device 4 includes regulating shaft 41, regulating handle 42, regulates steel wire 43, regulates silk thread 44; The tracheal intubation joint is fixedly connected tracheal intubation 13 times, and top connects tracheal intubation curvature adjusting device 4; Regulate an end of silk thread 44 and fix with the end of regulating steel wire 43, one is fixed on the terminal inwall of tracheal intubation 1, and the other end links to each other with regulating shaft 41.Adjusting steel wire 43 among the present invention with regulate silk thread 44 and interconnect with regulating shaft 41, regulate steel wire 43 and connect regulating shaft 41 versatilely, regulate silk thread 44 and be fixedly attached on the regulating shaft 41, between two junction points at a distance of half of the internal diameter of about tracheal intubation.
Tracheal intubation joint 3 can be structure as a whole with tracheal intubation adjusting device 4; Also can be the split structure; Tracheal intubation curvature adjusting device 4 also includes a tracheal intubation curvature and regulates seat 45; Regulating seat 45 through it is fixedly connected with tracheal intubation joint 3; Its type of attachment can be the tracheal intubation joint 3 outer tracheal intubation curvatures that are enclosed within and regulates on the seat 45, also can interior form fix of overlapping connect.
For the connected mode of integrative-structure form, its regulating shaft 41 is contained in the top of tracheal intubation joint 3 rotationally; For split version, its regulating shaft 41 is contained in the top that the tracheal intubation curvature is regulated seat 45 rotationally.Its type of attachment can adopt regulating shaft to pass in the cinclides of tracheal intubation curvature adjusting seat or tracheal intubation union joint, and two ends external wedge blocks.
The used adjusting gauge of wire of the present invention is about 0.3MM, and has certain elasticity; It regulates silk thread is about 0.2MM, and they are about diameter half the of tracheal intubation between the junction point on the regulating shaft, regulate steel wire and be connected versatilely with regulating shaft; Regulate steel wire and can be fixed under the preceding topic that guarantees with the horizontal range of regulating silk thread also that trachea is beaten pipe joint or the tracheal intubation curvature is regulated on the inwall of seat.
Have one being recessed into shoulder 412 with the hole 411 and that is fixedly connected at the junction point place that regulates silk thread 44 on the regulating shaft 41, clamping ring of suit on the recessed shoulder 412 is regulated steel wire and is connected with clamping ring; Regulating shaft 41 is regulated seat with tracheal intubation joint or tracheal intubation curvature rotationally through the hole 413 at its two ends and is connected.
In use, turn its regulating handle through hands and rotate regulating shaft, drive the adjusting silk thread that is fixed on the regulating shaft and be wrapped on the regulating shaft, thereby make tracheal intubation crooked; Lean on the elastic return original state of adjusting steel wire itself when after unclamping regulating handle or instead twisting regulating handle or be consistent with the shape of person's windpipe.
In the accompanying drawing: 1 is tracheal intubation; 2 is air bag; 3 is the tracheal intubation joint; 4 is tracheal intubation curvature adjusting device; 41 is regulating shaft; 42 is regulating handle; 43 for regulating steel wire; 44 for regulating silk thread; 45 for regulating seat; 411 is that connecting hole 412 is recessed shoulder; 413 is the hole.
