Abstract

The utility model relates to a novel trachea inserting tube, belonging to the field of anesthesia and emergency medical treatment equipment. The utility model is used for building an artificial airway. The utility model is composed of a low pressure air bag, a tube body, an air bag air injecting device, an outer joint and a hard moveable casing tube. Both ends of the outer surfaces of the upper and the lower walls of the hard moveable casing tube are respectively provided with a bulge with an inclined surface; the raised middle parts of the ends of the outer side surfaces of the upper and the lower walls of the hard moveable casing tube are provided with concaves. The upper parts of the inner side surfaces of the upper and the lower walls of the hard moveable casing tube are provided with convex blocks; the outer side surface of the hard movable casing tube is provided with a channel which is used for a phlegm absorbing tube. The utility model has the advantages of simple structure, easy use, simplified process of inserting the tube, etc.

Description

Novel tracheal intubation

Novel tracheal intubation belongs to anesthesia and emergency medical apparatus, when relating to oral trachea cannula tracheal intubation in the oral cavity fixing at the tooth place especially.

Set up the artificial airway in field extensive use tracheal intubatioies such as surgery anesthesia, first aids and carry out artificial ventilation.The tracheal intubation that adopts now in clinical is made up of low pressure air bag, pipe shaft, air bag gas injection device and external tapping etc.The rubber tracheal intubation that this tracheal intubation does not have air bag than before has advantages such as zest is little, histocompatibility good, indwelling time is long, thereby has been widely used.But this used tracheal intubation of while has flexibility and can not regulate, inhale shortcomings such as expectorant and oxygen supply inconvenience, and CN2148578, CN2149915 have announced solution respectively.Now another shortcoming with tracheal intubation is must place a bite-block (how being made by rubber tube or roller) after per os inserts between the upper and lower tooth of patient.Put bite-block and be used to prevent that patient's tooth is stung tracheal intubation to close to cause suffocates, have the effect of fixed air cannula simultaneously concurrently.Bite-block has occupied the most of oral cavity of patient inner area, and suction expectorant and mouth care have been brought very big difficulty after inserting to tracheal intubation, and is especially more obvious to the long patient of those tracheal intubation indwelling times.Simultaneously also can deviate to cause tracheal intubation to be snapped and close this mortality consequence because of bite-block.And prior art all can not solve because of placing these problems that bite-block brought.

The purpose of this utility model provides a kind of novel tracheal intubation simple in structure, easy to use.

The purpose of this utility model is achieved in that novel tracheal intubation, form by low pressure air bag, pipe shaft, air bag gas injection device, external tapping and the removable sleeve pipe of hard etc., it is characterized in that: on the tracheal intubation pipe shaft, be with a removable sleeve pipe of hard, respectively there is the protuberance on a band inclined-plane at the two ends of the removable telescopic upper and lower wall lateral surface of hard, there is depression the centre of the removable telescopic upper and lower wall lateral surface of hard two ends protuberance, has small lugs on the removable telescopic upper and lower wall medial surface of hard.

The utlity model has simple in structure, easy to use, can simplify existing tracheal intubation and insert operating process, and the manufacturing process of most of structure with now use the manufacturing process of tracheal intubation basic identical, easy to implement to promote at present.

Be structural representation of the present utility model below:

Figure one is the sketch map of this utility model embodiment.

Figure two is profilographs of the removable sleeve portion of this utility model hard.

Figure three is drawings in side sectional elevation of the removable sleeve portion of this utility model hard.

Figure four is cutaway views of this utility model pipe shaft part.

Figure five is that this utility model per os inserts the back at the fixed sketch map in tooth place.

Below in conjunction with drawings and Examples structure of the present utility model and operation principle are further described.

Figure one is the sketch map of this utility model embodiment, and visible this utility model is made up of the removable sleeve pipe 5 of low pressure air bag 1, pipe shaft 2, air bag gas injection device 3, external tapping 4 and hard.Show that as figure one the removable sleeve pipe 5 of hard can move on pipe shaft 2, with adapt to different patients the tracheal intubation insertion depth not simultaneously the removable sleeve pipe 5 of hard be movable to and between the upper and lower tooth patient stung to fasten, the length of the removable sleeve pipe 5 of hard should be between 1-3.5cm.

Figure two is profilographs of the removable sleeve pipe 5 of this utility model hard, respectively there is the protuberance 7 on a band inclined-plane at the two ends of upper and lower wall 6 lateral surface of the removable sleeve pipe 5 of hard, protuberance 7 has two inclined-planes 8,9, inclined-plane 8 is more smooth is convenient to moving of the removable sleeve pipe 5 of hard, and inclined-plane 9 directly is used to prevent that tooth from biting the removable sleeve pipe 5 of back hard and deviating from foot.There is a depression 10 in the central authorities of upper and lower wall 6 lateral surface of the removable sleeve pipe 5 of hard, are used to prevent deviate from after tooth from nipping.Upper and lower wall 6 medial surface 11 of the removable sleeve pipe 5 of hard have pellet shapes projection 12, and effect is to be beneficial to pipe shaft 2 and hard combining between will upper and lower wall 6 medial surface 11 of mobile sleeve pipe 5 to fix, and prevent that pipe shaft 2 from deviating from the removable sleeve pipe 5 of hard.

Figure three is drawings in side sectional elevation of the removable sleeve pipe 5 of hard, and its central cavity 13 is to place pipe shaft 2 usefulness, and it can be oval-shaped, and the internal diameter of central cavity 13 is greater than the external diameter of pipe shaft 2.The two side 14 of the removable sleeve pipe 5 of hard can surround a wing passage 15 and pass through for inhaling expectorant and balloon catheter.Wing passage 15 can be that a complete hole also can leaving certain gaps uncovered by the economic plan 16.

Figure four is cutaway views of this utility model pipe shaft part, and it is just basic identical with the tracheal intubation structure of present use as seen the removable sleeve pipe 5 of hard to be taken off back this utility model this moment on pipe shaft 2, can be used for via intranasal application and carries out intubate.The amplifier section of pipe shaft 2 as seen from figure, on the tube wall exterior 17 at nearly external tapping 4 places of pipe shaft 2 (being equivalent to upper and lower interdental part and each part of front and back thereof) some dolly dimples 18 are arranged, purpose is to reach the fixedly effect of pipe shaft 2 for the pellet shapes projection 12 that makes removable sleeve pipe 5 inner faces of hard sting tightly at tooth after can combine with the dolly dimple 18 on pipe shaft 2 tube wall exterior 17, and tube wall inner face 19 is still slick.

Figure five is that this utility model per os inserts the back at the fixed sketch map in tooth place, act on lateral surface 10 places of the removable telescopic 5 upper and lower walls 6 of hard when as seen the upper and lower tooth 20 of patient is exerted oneself interlock, because of the removable sleeve pipe 5 of hard has certain elasticity, pellet shapes projection 12 on removable sleeve pipe 5 upper and lower wall 6 medial surface 11 of hard combines with dolly dimple 18 on pipe shaft 2 tube wall exterior 17 under external force, make pipe shaft 2 be fixed in one with patient's tooth 20, can not make pipe shaft 2 move at the intracavity of the removable sleeve pipe 5 of hard by the removable sleeve pipe 5 of hard.

All parts of the present utility model are made by doctor PVC, and also available other of the removable sleeve pipe 5 of hard has certain elastic hard material and make.
