Abstract
The invention discloses a tracheal intubation guide which comprises a hollow tube. Guide indication marks axially distributed along the hollow tube are arranged on the inner wall of the hollow tube. The tracheal intubation guide is simple in structure, and by the aid of the guide indication marks arranged on the inner wall of the hollow tube, after a bronchoscope enters the hollow tube, an image mirror at the tube end can observe the guide indication marks, and operators only need to control the tube end of the bronchoscope to move forward along the guide indication marks. Therefore, the tracheal intubation guide is convenient and simple to operate, tracheal intubation of the bronchoscope can be completed quite quickly and accurately, and the tracheal intubation guide is pretty effective in use.
Description
Technical field
The present invention relates to a kind of guide device of endotracheal tube.
Background technology
Often use clinically at present the endoscope such as fiberoptic bronchoscope to carry out the observation of the lobe of the lung, section and inferior segmental bronchus pathological changes, biopsy is sampled, bacteriology, cytolgical examination etc.Fiberoptic bronchoscope generally need to be used guide and assist when carrying out tracheal intubation, first guide is inserted into patient's pars oralis pharyngis place during operation, then bronchoscope is provided with to extend to along guide as the pipe end of mirror and further enters into again bronchus or pulmonary place in the person's windpipe.In use at present; bronchoscope often can run into the problem that is difficult to distinguish direction when the guide section is advanced; although pipe end as mirror around can detecting image and can show at display; but for the medical personnel that lack experience; owing to significantly do not guide sign on the image, so the direct of travel of pipe end is difficult to extremely also differentiate.Medical personnel must repeatedly attempt correctly finishing bronchoscopic tracheal intubation work.Lower in critical condition, rescue opportunity can be greatly incured loss through delay in this operation, patient's life security even can receive threat.
Summary of the invention
For the problems referred to above, the invention provides a kind of simple in structure, guide device of endotracheal tube that result of use is good, fiberoptic bronchoscope can be finished tracheal intubation work easily under the mating reaction of this guide.
The present invention is that the technical scheme that its technical problem of solution adopts is:
Guide device of endotracheal tube comprises hollow tube, is provided with on the inwall of described hollow tube along the guiding sign of the axial directional distribution of hollow tube.
As preferred embodiment, described guiding sign is the strip indication colour band that is affixed on the inwall.
As preferred embodiment, described guiding sign is one to be arranged at the strip projected parts on the inwall.
As preferred embodiment, described guiding sign is one to be arranged at the strip groove on the inwall.
As preferred embodiment, described guiding sign is salient point or the concave point that one group of sequence interval is arranged.
The invention has the beneficial effects as follows: guide device of endotracheal tube of the present invention is simple in structure, its inwall at hollow tube arranges the guiding sign, after bronchoscope enters into hollow tube, its pipe end as mirror can observe this guiding sign, operator only need control bronchoscopic pipe end and advance forward always and just can along this guiding sign, easy to operate simple, bronchoscopic tracheal intubation work can be finished very quickly and accurately, and therefore guide of the present invention has very good result of use.
Description of drawings
Be further detailed below in conjunction with the drawings and specific embodiments:
Fig. 1 is the overall structure sketch map of guide device of endotracheal tube;
Fig. 2 is the cross-sectional view of the first embodiment of the present invention;
Fig. 3 is the cross-sectional view of the second embodiment of the present invention;
Fig. 4 is the cross-sectional view of the third embodiment of the present invention;
Fig. 5 is the cross-sectional view of the 4th kind of embodiment of the present invention.
The specific embodiment
With reference to Fig. 1, the guide device of endotracheal tube structure comprises hollow tube 1, and during use, this hollow tube 1 is inserted into patient's pars oralis pharyngis place, and bronchoscope is the downward trachea place that reaches the patient of guiding function of blank pipe body 1 hereinto.In order to play better guiding function, be provided with on the inwall of hollow tube 1 of the present invention along the guiding sign of the axial directional distribution of hollow tube.This guiding sign can be identified by bronchoscopic picture mirror, and operator only need just can successfully advance in guide along this sign.
Fig. 2 is the first embodiment of the present invention, and in this embodiment, the guiding sign is the strip indication colour band 20 that is affixed on the inwall.The color of this strip indication colour band 20 is different from the inwall color of hollow tube 1, plays the effect of distinguishing guiding.
In the embodiments of figure 3, the guiding sign is one to be arranged at the strip projected parts 21 on the inwall.This projection 21 exceeds the inwall certain altitude, bronchoscopicly also can more easily tell this projection 21 as mirror.
In the embodiment of Fig. 4, the guiding sign is one to be arranged at the strip groove 22 on the inwall.With the similar of strip projected parts 21, bronchoscopicly also can easily it be distinguished as mirror.
In the embodiment of Fig. 5, the guiding sign is the salient point 23 that one group of sequence interval is arranged, and bronchoscopic pipe end only needs to advance along these salient points 23, just can successfully finish fast tracheal intubation work.Certainly, above-mentioned salient point 23 also can utilize concave point to replace, and perhaps salient point 23 and concave point can arrange at the interval.
Embodiments of the present invention are not restricted to the described embodiments, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
