Description
Technical field
The utility model belongs to the field of medical instrument technology, especially a kind of tracheal catheter.
Background technique
Currently, endotracheal intubation refers to special tracheal catheter, it is inserted into patient's trachea by oral cavity or nasal cavity.Gas
Cannula technology have become ensure general anesthesia operation go on smoothly, CPR and the Severe acute disease patient with respiratory dysfunction
Important measures during rescue are most widely used, most effective most efficiently one of means in management of respiratory, are medical matters people
The basic skills that member must skillfully grasp.
It is intracorporal in pipe that existing tracheal catheter generally comprises hollow tube body, inflatable cuff, inflating catheter and setting
Spiral wire, inflating catheter are arranged on the inner wall of tube body, and one end of tube body is arranged in inflatable cuff, and inflating catheter and inflation cover
Capsule connection, the setting of spiral wire is so that the flexibility of tube body has obtained great promotion, so that tube body can be by more soft material
Matter is made, and can change with Upper airway, agrees with that degree is preferable, reduces the friction with mucous membrane tissue, damage it is smaller,
Complication can be effectively controlled.
But once patient occurs stinging pipe, the tube body place of being snapped is easily deformed, and leads to pipe intracorporal spiral wire deformation, spiral
It is not easy replica after steel wire deformation, therefore is snapped the tubular body space relatively narrower at place, airway patency, suction sputum nursing is influenced, increases
Tracheal catheter rate is replaced, Preserving time is not easy to.
Summary of the invention
Deformation can not after one kind that in order to overcome the deficiencies of the prior art, the utility model provides avoids spiral wire from being snapped
Recovery causes tube body narrow, influences the tracheal catheter of airway patency.
To achieve the goals above, the technical solution adopted in the utility model is: a kind of tracheal catheter, including hollow pipe
In the intracorporal spiral wire of pipe, inflating catheter is arranged on the inner wall of tube body, fills for body, inflatable cuff, inflating catheter and setting
One end of tube body is arranged in air-casing capsule, and inflating catheter is connected to inflatable cuff, and the spiral wire setting has inflation in tube body
One end of cuff, the length of spiral wire are 10cm-20cm.
In above-mentioned technical proposal, spiral wire only covers the head end of tube body, and the tail end of tube body is leading without spiral wire
Pipe, because the length of tube body is different, so the length of spiral wire is also different, when adult is intubated, tube body is inserted into endotracheal depth
Degree is 4-5cm, and the distance of tube body head end to front tooth is about 18-22cm, and the length of preferred spiral wire can be 15cm or so,
It not only can guarantee plasticity and successful intubation of the tube body in catheterization procedure in this way, but also can prevent during tracheal catheter indwelling
Cause tube body narrow because patient stings pipe, influence the nursery works such as airway patency and suction sputum, save built-in spiral wire completely
Advantage.
As the further setting of the utility model, the length of the spiral wire is 13cm-17cm.
It further include the suction tube being arranged on inboard wall of tube body as the further setting of the utility model, the tube body
It is connected with suction sputum set at head end, is provided at the port of suction sputum set along its circumferentially distributed sputum suction hole, axis of the sputum suction hole along tube body
To being extended, the end of each sputum suction hole, which is interconnected, forms circular passage, and circular passage is connected to suction tube, suction tube
The tube wall that the other end is pierced by tube body is connect with sputum aspirator.
In above-mentioned technical proposal, sputum suction hole is circumferentially distributed along suction sputum set port, expands suction sputum range, as far as possible completely
Remove sputum or dirt, avoiding omitting influences airway patency, discharge because of respiratory disorder caused by sputum blocking, and sputum suction hole it is more and
It is evenly distributed, does not have to too powerful sputum aspirator just to operate, if the power of sputum aspirator will cause greatly very much the discomfort of patient, or cause
The damage of its wall of laryngeal cavity, suction sputum set is mating with tube body, and each sputum suction hole is connected to by circular passage with suction tube, synchronous work
Make, improve suction sputum efficiency, shortens the time, structure is simple, easy to use.
As the further setting of the utility model, the suction sputum set is towards being provided with the first ring on the inner wall of end of tube body
Shape boss, circular passage are arranged in first annular boss, and the tube body is far from being provided with the second ring on the inner wall of end of head end
Shape boss, the both ends of spiral wire are connected to respectively on first annular boss and the second annular convex platform.
In above-mentioned technical proposal, when installation, first by spiral wire loading tube body, then suction sputum set and tube body grafting, make
The both ends of spiral wire are abutted with first annular boss and the second annular convex platform respectively, the diameter of spiral wire and the internal diameter of tube body
Adaptation, circular passage is circumferentially distributed along first annular boss, and the outer peripheral surface of suction sputum set is flushed with the outer peripheral surface of tube body, avoids drawing
Hurt wall of laryngeal cavity, it is easy to process, prolong the service life.
As the further setting of the utility model, it is to be obliquely installed that the suction sputum, which covers the port far from tube body,.
In above-mentioned technical proposal, the port of suction sputum set is the tip being obliquely installed, and tube body is facilitated to be inserted into air flue, reduction and gas
The friction of road inner wall, prevents plowing from wall of laryngeal cavity, using safer convenient.
As the further setting of the utility model, the tube body includes inner and outer tubes, and inner and outer tubes are at upper end phase
Even, lower end fitting setting, inflatable cuff is set in the lower section on the outer wall of inner tube and being located at outer tube, within said inner tube in formation
Chamber forms exocoel between outer wall of inner tube and outer tube wall, exocoel is connected to suction tube, and the outer tube is towards the outside of inflatable cuff
It is provided with lateral incision hole, lateral incision hole is located at the top of the inflatable cuff and is connected to exocoel.
In above-mentioned technical proposal, ciliary movement of the patients with mechanical ventilation due to swallowing reflex, cough reflex and lower respiratory tract
Weaken or disappear, oropharynx secretions and field planting bacterium easily accumulate in the space above inflatable cuff and in " pocket " shape, become thin
The repository of bacterium, therefore effectively to prevent VAP, then the secretion above inflatable cuff must be timely and effectively removed,
Continuously suctioning secretions directly reduce oral pharynx nasalis under until having aspirated for suction tube and the cooperation of lateral incision hole
The lower leakage of respiratory secretions and field planting bacterium migrate, and facilitate the incidence for reducing postoperative pulmonary complications in hospital, delay to exhale
The generation of suction machine pneumonia.
Using the above scheme, deformation, which can not restore, after spiral wire can not only being prevented to be snapped causes tube body narrow, influences gas
The unobstructed problem in road, moreover it is possible to sputum and secretion be removed by suction tube in time, the incidence of postoperative complications is reduced, avoid phlegm
Liquid is had difficulty in breathing caused by blocking, and improves safety, and using more convenient, structure is simple, easy to process.
The utility model is further described with reference to the accompanying drawing.
