Abstract
A tracheal tube is designed to be widely applicable and used conveniently. The tracheal tube comprises a front segment and a rear segment, wherein a side hole and an expansion ball bag are arranged at the front segment of the tube; the side hole is formed at an opening close to the front end of the tube; the expansion ball bag is arranged behind the side hole; an inflating channel, an inflating hole and a conversion joint are arranged at the rear segment of the tube; the inflating channel comprises an inner gas channel and an outer gas channel; the inner gas channel is the front half part of the tube and is arranged in the tube, and the front end of the inner gas channel extends to the front segment of the tube and is communicated with the expansion ball bag; the outer gas channel is the rear half part of the inflating channel and is arranged outside the tube, and the rear end of the outer gas channel is connected with the inflating hole; a boundary point of the inner gas channel and the outer gas channel of the inflating channel is at the middle part of the rear segment of the tube; an included angle of 120 to 150 DEG is formed between the front segment and the rear segment of the tube; the included angle is smoothly transitional; and the conversion joint is arranged at the rear end of the tube.
Description
Technical field
This utility model relates to a kind of endotracheal tube.
Background technology
When hospital's general anesthesia (in the process) intubate and rescue critical patient, often need be that patient's intubate helps to breathe.Except that disease itself causes the patient respiratory difficulty, in rescuing the intubate process, need in time to set up the artificial airway, but often some patient's tracheal intubation is not too smooth.Existing endotracheal tube mainly is a curved catheter, expose the above exposure of classification III level and do not go out the glottis situation if run into laryngoscope in the use, curved catheter need add tube core auxiliary become the shape with certain angle could (successfully setting up the artificial airway) intubate successfully.Propose L shaped pipe in the document that has,, cause the damage of glottis easily,, may cause life danger critical patient as untimely processing because the angle of L shaped pipe is the right angle.
Summary of the invention
The purpose of this utility model is for overcoming the deficiency of above-mentioned prior art, a kind of endotracheal tube applied widely, easy to use being provided.
This utility model endotracheal tube comprises forward and backward two sections, is provided with side opening and dilatation balloon at the conduit leading portion, and side opening is located near the catheter proximal end opening part, and dilatation balloon is located at the side opening back; The conduit back segment is provided with inflation road and inflation inlet, translation interface; Air flue and exterior air drain in the inflation road comprises, interior air flue is the first half of conduit, is located in the conduit, its front end extends to the conduit leading portion, and is communicated with dilatation balloon; Exterior air drain is latter half of for the inflation road, is located at outside the conduit, and its rear end is connected with inflation inlet.The separation of the inside and outside air flue in inflation road is positioned at the middle part of conduit back segment.Form the angle of one 120-150 degree between forward and backward two sections of the conduit, the angle is a rounding off; Translation interface is located at rear end of conduit.
About 2-the 2.5cm of dilatation balloon length; Segment length 4-5cm before the conduit.The separation of the inside and outside air flue in inflation road is at distance catheter proximal end 14-18cm place.Endotracheal tube adopts silica gel material to make.The catheter proximal end opening direction down, open lower end is apart from open upper end 1-1.5cm.
The alternative existing endotracheal tube of this utility model uses.This utility model structure is more reasonable, uses more conveniently, and the patient who can not expose glottis for normal patient and laryngoscope all can directly use, and does not need during intubate to assist intubate with tube core and fiber tracheascope equipment; Applied widely.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, side opening, 2, the conduit leading portion, 3, dilatation balloon, 4, air flue in the inflation road, 5, inflate the road exterior air drain, 6, translation interface, 7, the conduit back segment, 8, inflation inlet, 9, front opening.
The specific embodiment
Conduit leading portion 2 is provided with side opening 1 and dilatation balloon 3; Conduit back segment 7 is provided with air flue 4 in the inflation road, inflation road exterior air drain 5, inflation inlet 8 and translation interface 6; Air flue 4 is located in the endotracheal tube in the inflation road, and its front end is communicated with dilatation balloon 3; Inflation road exterior air drain 5 is located at outside the conduit, and its rear end is connected with inflation inlet 8.The included angle A that forms between conduit leading portion 2 and the conduit back segment 7 is 120-150 degree; Translation interface 6 is located at rear end of conduit.Catheter proximal end opening 9 is opened down.
Dilatation balloon 3 length are 2cm; Conduit leading portion 2 length 4.5cm.Separation in the inflation road between air flue 4 and the inflation road exterior air drain 5 is at distance catheter proximal end 16cm place.The following end distance open upper end 1.2cm of catheter proximal end opening 9.
