Tube made of film and trachea cannula

Abstract

The invention belongs to the field of pipes, and provides a pipe made of a thin film, which is divided into at least one support section and a natural number of non-support sections which are connected with each other, the supporting section is formed by sleeving an inner-layer film pipe and an outer-layer film pipe together, the inner-layer film pipe and the outer-layer film pipe are connected at the two ends of the supporting section to form a closed pipe wall interlayer, and a plurality of local adhesion parts are arranged between the pipe walls of the inner-layer film pipe and the outer-layer film pipe of the supporting section; pressure fluid is filled between pipe wall interlayers, the pressure is kept not leaking, a supporting fluid bag can be formed, and after the supporting fluid bag is filled with the pressure fluid and keeps the pressure, internal and external positive or negative pressure and bending can be resisted, and the inner-layer thin film pipe is kept through; the non-supporting section of the pipe is composed of at least one layer of film pipe and mainly plays a role in connecting various pipe joints and the like. The technical scheme provided by the invention has the advantages of being low in manufacturing cost, convenient to use, small in tube insertion and extraction damage, convenient in tube insertion and extraction and more environment-friendly.

Description

technical field [0001] The invention belongs to the field of tubes, in particular to a trachea tube and a tracheal intubation tube of a medical ventilator and a tube that requires tube diameter support. Background technique [0002] In the respiratory department in the medical field, most of the ventilator trachea and tracheal intubation are disposable. For patients who need to use the ventilator for a long time, the consumption of the ventilator trachea and tracheal intubation is not a small expense. In addition, the ventilator trachea and tracheal intubation need to have strength because they need to be able to pass through under positive and negative pressure. Therefore, the ventilator trachea generally adopts a tube with a support structure, while the endotracheal intubation uses a thicker wall thickness. In the application of tracheal intubation, the turning point of the human airway brings inconvenience to the insertion of the tracheal intubation, so the outer diameter...

Problems solved by technology

[0002] In the respiratory department in the medical field, most of the ventilator trachea and tracheal intubation are disposable. For patients who need to use the ventilator for a long time, the consumption of the ventilator trachea and tracheal intubation is not a small expense. ;In addition, the ventilator trachea and tracheal intubation need to have strength because they need to be able to pass under positive and negative pressure. Therefore, the ventilator trachea generally adopts a tube with a support structure, while the tracheal intubation uses a thicker wall thickness. In the application of tracheal intubation, the turning point of the human airway brings inconvenience to the insertion of the tracheal intubation, so the outer diameter of the tracheal intubation is expected to be as small as possible to reduce the harm of the intubation to the patient. The machine hopes that the tube passage of the tracheal intubation is large enough to improve the ventilation efficiency. The above contradictions make the tracheal intubation require more precise size control and size semicolon. Whether the tube with a support structure or the above contradictions in the tracheal intubation exist indirectly pushed up the cost

[0003] At present, there is no solution that can solve the above contradictions at the same time, so a better technical solution for the above problems is valuable
