Abstract

The utility model provides an improved reinforced trachea cannula, which relates to a medical trachea cannula with the advantages of both the ordinary trachea cannula and the reinforced trachea cannula. The improved reinforced trachea cannula is widely applied to the fields of clinical anesthesia, first aid, intensive care therapy and the like. The front part of the improved reinforced trachea cannula is an ordinary silicone tube, the back part is a steel wire reinforced silicone tube, and the front and back proportion distribution is different according to different models, a transition part of the ordinary silicone tube at the front part and the reinforced silicone tube at the back part has the gradually reduced reinforced steel wires, and easy fracture and permanent fracture at the connecting part are avoided, the ordinary silicone tube at the front part and the reinforced silicone tube at the back part maintain the uniform outer diameter, and the inner diameter is in gradual transition at the connecting part, the ordinary silicone tube at the front part needs to have a certain bending angle to be favorable for intubatton, and a sleeve bag inflating tube extends in a tube wall of the silicone tube and is connected with a sleeve bag at the front end. The part at the front end of the improved reinforced trachea cannula placed into an air passage has the hardness and the adaptability of the front end of the original tracheal catheter, and the parts outside the mouth or the nose have the flexibility and the intensity of the reinforced trachea cannula.

Description

Improve reinforced tracheal intubation

Affiliated technical field:

The present invention relates to a kind of medical tracheal intubation, have plain edition and the advantage that adds the epistasis tracheal intubation concurrently, be widely used in fields such as clinical anesthesia, first aid, Intensive Care Therapy treatment.

Background technology:

The advantage of medical common tracheal intubation is that hardness is higher, the conduit external diameter is thinner relatively, and is handling good; Shortcoming is that little, the easy dead folding of mobility, the urgent intensity of resistance to compression are lower.

The advantage of medical reinforced endotracheal tube is that the intensity height is compeled in big, the difficult dead folding of mobility, resistance to compression, shortcoming is that front end softness, hardness are low, the conduit external diameter is thicker relatively, when difficult intubation, be difficult for glottis involutory, even if insert the hard tube core also exist conduit handling poor, easily cause the situation of the secondary damage of pars oralis pharyngis.

The utility model summary of the invention:

The technical problem that solves:

According to the clinical anesthesia working experience, what in most of the cases the clinical anesthesia tracheal intubation needed is above pliability and intensity of oropharynx, and oropharynx is following, and we expect good handling and relative thin external diameter! Therefore, we have designed modified form and have strengthened the shortcoming that endotracheal tube has the advantage of reinforced and common endotracheal tube concurrently and remedies traditional reinforced endotracheal tube.

Solving the technical scheme that its technical problem adopts is:

Improve reinforced tracheal intubation, its front end is inserted glottis and is reached hardness and the compliance that partly has common endotracheal tube with downtake, and glottis possesses the pliability and the intensity of reinforced tracheal intubation with top.Key technique: 1, silica gel tube length separately and front and back ratio are on the whole strengthened in forward ordinary silicon sebific duct and rear portion; 2, the transition position between forward ordinary silicon sebific duct and the rear portion reinforcement silica gel tube should be the minimizing gradually of strengthened steel wire, avoids junction folding easy to break and dead; 3, forward ordinary silicon sebific duct should keep the consistent of external diameter with rear portion reinforcement silica gel tube, in the transition gradually of junction internal diameter; 4, forward ordinary silicon sebific duct should have certain angle of bend to be beneficial to intubate.5, the processing of silica gel tube junction sleeve bag gas-filling pipe is strengthened at forward ordinary silicon sebific duct and rear portion.

The beneficial effects of the utility model are:

Improve reinforced tracheal intubation, its front end is inserted glottis and is reached hardness and the compliance that partly has common endotracheal tube with downtake, and glottis possesses the pliability and the intensity of reinforced tracheal intubation with top.

1. be applied to have difficulties in the incidence surgery anesthesia of air flue, increase successful intubation, reduce the secondary damage of pars oralis pharyngis; When 2. being applied to old people's front tooth incompleteness and can't placing bite-block; 3. do not place the headstock after the requirements of operation intubation and general anaesthesia, and will guarantee that dead folding does not take place tracheal intubation, as situations such as radiotherapies in mammary cancer surgery, the art; 4. increase successful intubation during the children with tracheal intubate; 5. thicker lumen diameter relatively can be provided during the branchofiberoscope guidance tracheal intubation.Summarize, can replace plain edition commonly used clinically at present and add the epistasis tracheal intubation.

Description of drawings:

Improve reinforced tracheal intubation schematic view illustrating:

1, duroplasts standard tracheal intubation interface

2, circular hollow contains the silica gel tube of spiral wire internal fixation

3, be used for the sleeve bag gas-filling interface of front end sleeve capsule (shown in the note 8) inflation, its injection section can show front end sleeve capsule filling degree

4, tracheal intubation main body overcoat capsule connection tube

5, cover capsule connection tube in the tracheal intubation main body

6, spiral wire internal fixation transition portion from spare to dense

7, the hard silica gel tube of circular hollow transparent

8, the height of tracheal intubation front end holds low gland capsule

9, become the oblique type opening of miter angle with crooked radian sagittal plane (longitudinal section), section is made anti-scratch and is handled

10, be positioned at the silica gel tube of the above spiral wire internal fixation of glottis after the tracheal intubation, high strength, high-flexibility

11, be positioned at the common tracheal intubation of glottis and following no internal fixation after the tracheal intubation

The specific embodiment:

The front portion of whole tracheal intubation is the ordinary silicon sebific duct, and the rear portion is that steel wire is strengthened silica gel tube, according to pro rate difference before and after the model difference; The transition position that strengthen between the silica gel tube at forward ordinary silicon sebific duct and rear portion should be the minimizing gradually of strengthened steel wire, avoids junction folding easy to break and dead; Forward ordinary silicon sebific duct is strengthened silica gel tube with the rear portion should keep the consistent of external diameter, in the transition gradually of junction internal diameter; Forward ordinary silicon sebific duct should have certain angle of bend to be beneficial to intubate; The sleeve bag gas-filling pipe extends in the silica gel tube tube wall and connects the cover capsule of front end.

Claims

1. improve reinforced tracheal intubation for one kind, front end is inserted glottis and is partly had the hardness and the compliance of common endotracheal tube with downtake, glottis possesses the pliability and the intensity of reinforced tracheal intubation with top, the front portion that it is characterized in that tracheal intubation is the ordinary silicon sebific duct, the rear portion is that steel wire is strengthened silica gel tube, according to pro rate difference before and after the model difference; The transition position that strengthen between the silica gel tube at forward ordinary silicon sebific duct and rear portion is the minimizing gradually of strengthened steel wire; Forward ordinary silicon sebific duct is strengthened silica gel tube with the rear portion and is kept the consistent of external diameter, in the transition gradually of junction internal diameter; Forward ordinary silicon sebific duct has certain angle of bend to be beneficial to intubate; The sleeve bag gas-filling pipe extends in the tracheal intubation tube wall and connects the cover capsule of front end.
