Abstract
This utility model provides a kind of tracheal casing pipe, relates to medical instruments field, can regulate the gas flow of turnover tracheal casing pipe, and then more accurately regulates plugging area when plugging.The tracheal casing pipe of the present embodiment comprises trocar sheath and the inner sleeve supporting with trocar sheath, and the top of described trocar sheath is provided with lower blade and rotatable blade, regulates the gas flow of the described tracheal casing pipe of turnover by rotating described blade.
Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of tracheal casing pipe.
Background technology
Cervical trachea cuts in bronchotomu system, puts into tracheal casing pipe, to remove dyspneic a kind of common surgical caused by the not normal or lower respiratory tract ischesis of laryngeal dyspnea, breathing function.General patient consciousness recovering state or the state of an illness steadily after can consider extubation, when the state of an illness allows to pull out tracheal casing pipe, first try plugging, plugging method is 1/2 of the first gas shutoff pipe box mouth of pipe, then 3/4 of the gas shutoff pipe box mouth of pipe, finally plugging entirely.At present, the plugging used clinically is plugged with rubber, cork, cotton swab and adhesive plaster etc., but existing pipe stopper all can not fine adjustment plugging area; And disinfect tight, easily cause secondary infection, particularly cotton swab, adhesive plaster class article, along with breathing, have suction trachea to cause the danger suffocated.
Utility model content
Embodiment of the present utility model provides a kind of tracheal casing pipe, can regulate the gas flow of turnover tracheal casing pipe, and then more accurately regulates plugging area when plugging.
For achieving the above object, embodiment of the present utility model adopts following technical scheme:
A kind of tracheal casing pipe, comprise trocar sheath and the inner sleeve supporting with trocar sheath, it is characterized in that, the top of described trocar sheath is provided with lower blade and rotatable blade, regulates the gas flow of the described tracheal casing pipe of turnover by rotating described blade.
Be provided with in described trocar sheath for filtering and the drainage screen of humidified gas.
The tracheal casing pipe that this utility model provides, arranges lower blade and rotatable blade at the top of trocar sheath, when pulling out tracheal casing pipe, by rotating described blade, more accurately regulate plugging area, and then carries out safe tracheal casing pipe and pull out.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is this utility model tracheal casing pipe structural representation one;
Fig. 2 is this utility model tracheal casing pipe structural representation two.
Description of reference numerals: 1, tracheal casing pipe; 10, trocar sheath; 11, inner sleeve; 12, lower blade; 13, blade; 14, drainage screen.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
As shown in Figure 1, this utility model embodiment provides a kind of tracheal casing pipe 1, comprise trocar sheath 10 and the inner sleeve 11 supporting with trocar sheath 10, the top of described trocar sheath 10 is provided with lower blade 12 and rotatable blade 13, regulates the gas flow of the described tracheal casing pipe 1 of turnover by rotating described blade 13.
Further, as shown in Figure 2, be provided with in described trocar sheath 10 for filtering and the drainage screen 14 of humidified gas.
Tracheotomy patients, usually needs tentative plugging before tube drawing, and the object of tentative plugging is that whether observe patient can transition be that mouth and nose are breathed, and pulls out tracheal casing pipe smoothly.When the tracheal casing pipe using this utility model to provide, as shown in Figure 1, blade 13 is rotated, blade 13 is more with the lap of lower blade 12, the gas flow of turnover tracheal casing pipe 1 is more, when blade 13 and lower blade 12 are completely overlapping, realizes 1/2 of the gas shutoff pipe box mouth of pipe; Rotate blade 13, blade 13 is fewer with the lap of lower blade 12, and the gas flow of turnover tracheal casing pipe 1 is fewer, realizes 3/4 of the gas shutoff pipe box mouth of pipe; Continue to rotate blade 13, when blade 13 and lower blade 12 are not overlapping, realize full plugging.
The tracheal casing pipe that this utility model provides, arranges lower blade and rotatable blade at the top of trocar sheath, when pulling out tracheal casing pipe, by rotating described blade, more accurately regulate plugging area, and then carries out safe tracheal casing pipe and pull out.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
