Abstract
The utility model discloses a kind of tracheal cannula, it is provided with and is fixedly connected with its inwall in body, and the inflation threaded framework helically moved towards; Inflation threaded framework inner hollow, its front end is closed, and tail end is connected with gas tube, and gas tube extends to outside from the sidewall of body afterbody, and the tail end of gas tube is connected with gas-charging connection; Body and inflation threaded framework adopt elastoplast to make.Proper amount of gas can be filled with as required in inflation threaded framework during use, make body have suitable intensity, make body can ensure smooth intubate, the physiological bending of respiratory tract can be adapted to again fully, reduce patient uncomfortable, also can reduce the enforcement difficulty of intubate.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of tracheal cannula.
Background technology
At present in the treatment of patient with severe symptoms, direct oral cavity inserts endotracheal tube, be the most frequently used artificial airway set up mode, because adapt to the flexibility of air flue in human body and avoid causing contusion to respiratory tract in catheterization procedure, tracheal intubation selects the good material of suppleness to make usually, but in actual intubation process, often because body is too soft, lack enough rigidity and can not insert destination locations fast, cause operation comparatively to bother, efficiency is lower.And be generally and overcome this problem, must adopt guide to assist and carry out, further increase the triviality of intubation, and the elasticity of guide is fixing, can not regulate as required, there is very large technical deficiency in electricity in operation.In addition, tracheal intubation should have enough bores, and this bore specification is fixing inconvenience from the beginning to the end, as thinner intubate is conveniently carried out, but does not reach medical demands; And slightly certainly will add intubate enforcement difficulty as crossed, and easily damage is caused to respiratory tract wall.
Utility model content
For overcoming prior art problem, this utility model provides a kind of reasonable in design, convenient to operation, and it is easy, efficient that intubate is implemented, and can ensure the tracheal cannula of enough caliber sizes.
For realizing above-mentioned technical purpose, this utility model by the following technical solutions: a kind of tracheal cannula, comprises body, it is characterized in that: be provided with in described body and be fixedly connected with its inwall, and the inflation threaded framework helically moved towards; Described inflation threaded framework inner hollow, its front end is closed, and tail end is connected with gas tube, and gas tube extends to outside from the sidewall of body afterbody, and the tail end of gas tube is connected with gas-charging connection; Described body and inflation threaded framework adopt elastoplast to make.
This utility model has following beneficial effect: when after insufflation gas in inflation threaded framework, body is made to have enough intensity, avoid catheterization procedure middle tube body too soft and cannot advance, because its intensity provides primarily of inflation threaded framework, and inflate the helicitic texture that threaded framework has and ensure that inflation threaded framework has good bending property, make body fully can adapt to the physiological bending of respiratory tract, reduce patient uncomfortable; Because the aeration quantity in inflation threaded framework can conveniently control, therefore the elasticity of body can regulate easily according to case individual variation.In addition, due to the increase along with inflation threaded framework aeration quantity, the bore of body will certainly increase, according to this characteristic, a small amount of gas can be filled with in inflation threaded framework when intubate, make body bore less, so that the smooth enforcement of intubate, after band catheter position is fixing, continue insufflation gas in inflation threaded framework, protect expropriation and management body and there is enough bores to meet medical demands.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure, 1, inflation threaded framework, 2, gas-charging connection, 3, gas tube, 4, body.
Detailed description of the invention
Shown in Fig. 1, a kind of tracheal cannula disclosed in this utility model, comprises body 4, it is characterized in that: be provided with in described body 4 and be fixedly connected with its inwall, and the inflation threaded framework 1 helically moved towards; Described inflation threaded framework 1 inner hollow, its front end is closed, and tail end is connected with gas tube 3, and gas tube 3 extends to outside from the sidewall of body 4 afterbody, and the tail end of gas tube 3 is connected with gas-charging connection 2; Described body 4 and inflation threaded framework 1 adopt elastoplast to make.When after insufflation gas in inflation threaded framework 1, body 4 is made to have enough intensity, avoid catheterization procedure middle tube body 4 too soft and cannot advance, because its intensity provides primarily of inflation threaded framework 1, and inflate the helicitic texture that threaded framework 1 has and ensure that inflation threaded framework 1 has good bending property, fully can adapt to the physiological bending of respiratory tract, reduce patient uncomfortable; Due to can conveniently control at most in inflation threaded framework 1, therefore the elasticity of body 4 can regulate according to case individual variation easily.Due to the increase along with inflation threaded framework 1 aeration quantity, the bore of body will certainly increase, according to this characteristic, a small amount of gas can be filled with in inflation threaded framework 1 when intubate, make the bore of body 4 less, so that the smooth enforcement of intubate, after band catheter position is fixing, continue insufflation gas in inflation threaded framework 1, ensure that body 4 has enough bores to meet medical demands.
