Description
Technical Field
The invention relates to a cuttable reinforced tracheal cannula and an integrated fixing device, and belongs to the technical field of medical instruments.
Background
Tracheal intubation is an important measure for establishing an effective respiratory channel for patients with anesthesia operation, cardiopulmonary resuscitation and respiratory dysfunction. There are two types of prior art endotracheal tubes: common trachea cannula and reinforced trachea cannula. The common trachea cannula is made of hard materials to ensure the strength without bending, can be cut to adjust the length, but easily causes the injury of the throat and the airway of a patient due to the over hard materials; the reinforced tracheal cannula is made of soft materials, has small damage to the pharynx and the airway of a patient, but can not be cut to adjust the length because the wall of the tracheal cannula needs to be embedded with a metal wire reinforcing rib to ensure the strength and not to be bent. In addition, the two kinds of trachea cannula are used by additionally arranging a fixing device to ensure the position of the trachea cannula to be fixed.
Disclosure of Invention
The present invention solves the above problems by improving the structure of the existing endotracheal tube.
The invention provides a cuttable reinforced tracheal cannula and an integrated fixing device, wherein the cuttable reinforced tracheal cannula and the integrated fixing device comprise a tracheal cannula, a fixing tube, a telescopic tube and a tracheal cannula joint; one end of the tracheal cannula is a cuttable part, and the other end of the tracheal cannula is a part with a reinforced tube wall; the cuttable end of the tracheal cannula penetrates through the fixed tube and the telescopic tube to be fixedly connected with the tracheal cannula joint; the fixed pipe is movably connected with one end of the telescopic pipe; the other end of the extension tube is fixedly connected with the trachea cannula joint.
According to the invention, a metal reinforcing rib is embedded in the pipe wall of the pipe wall reinforcing part preferably.
The invention preferably has internal threads on the inner wall of the fixed tube; the outer wall of one end of the extension tube is provided with an external thread; the fixed pipe is movably connected with the telescopic pipe through threads.
The invention preferably adopts the structure that the inner ring at one end of the trachea cannula joint is a trachea cannula interface, and the outer ring is a telescopic tube interface; the trachea cannula interface of the trachea cannula joint is fixedly connected with the cuttable end of the trachea cannula; the telescopic pipe interface of the trachea cannula joint is fixedly connected with the other end of the telescopic pipe, so that the other end of the telescopic pipe is arranged between the telescopic pipe interface of the trachea cannula joint and the shearable end of the trachea cannula.
The tracheal intubation is characterized in that a positioning air bag is arranged at the reinforced end of the tracheal intubation wall and is connected with an airway valve through a ventilation pipeline.
The invention has the beneficial effects that:
firstly, the trachea cannula not only keeps the advantages of the non-reinforced trachea cannula that the length can be cut and adjusted, but also avoids the defect that the pharynx and the airway of a patient are easy to be damaged, and simultaneously, overcomes the defect that the reinforced trachea cannula can not be cut and adjusted;
the fixing device and the trachea cannula are integrated, so that two traditional products are changed into one product, and the production and use cost is greatly reduced;
the fixing device and the trachea cannula are integrated and sleeved on the trachea cannula, so that a large amount of space around the trachea cannula is saved, and great convenience is brought to oral cavity nursing;
the telescopic pipe not only has the function of adjusting the position of the fixing device, but also avoids the defect that the non-reinforced part of the tracheal cannula is easy to bend.
