Embodiment Construction

[0021] Embodiment of the present invention is described below in conjunction with accompanying drawing, embodiment does not constitute limitation of the present invention:

[0022] Option One:

[0023] A variable diameter catheter is characterized in that it includes a catheter body, and the catheter body includes a soft part and a hard part, and adopts one of the following schemes: A. The soft part and the hard part are distributed alternately, so that the whole The diameter of the pipeline is variable; B. The soft part and the hard part can form the whole pipeline, and the soft part and the hard part are respectively arc-shaped. Scheme A is embodiment one; scheme B is embodiment two. The substantive technical effect and the realization process of the technical solution here are as follows: using any catheter as described above, the soft part and the hard part of the catheter are partially folded, and the soft part will be folded, so that the overall pipeline Caliber change...

Abstract

The invention relates to the field of medical treatment, in particular to a variable-diameter catheter and a variable diameter method. The variable-diameter catheter comprises a catheter body which comprises a soft part and a hard part; one of the following schemes that 1, the soft part and the hard part are distributed alternatively, and the whole catheter diameter is variable; 2, the soft part and the hard part can form the whole catheter, and the soft part and the hard part are each shaped like an arc is adopted. The variable-diameter catheter and the variable diameter method have the advantages that any catheter is utilized, the soft part and the hard part of the catheter are locally folded, the soft part can be folded, and the whole catheter aperture is changed. The variable-diameter catheter is suitable for children and adults for use, foreign body sensation cannot be caused to people, and if people feel uncomfortable, the catheter diameter becomes smaller after being folded.

Description

technical field [0001] The invention relates to the medical field, in particular to a variable-diameter catheter and a method for reducing the diameter. Background technique [0002] The defective of prior art is: [0003] Different people have different physiological conditions, and the thickness of their trachea is different. However, the pipes in the hospital are all standard, and the thickness cannot be changed. Sometimes the patient feels very uncomfortable and feels a foreign body sensation. Sometimes catheters cannot be equipped with a full range of tubing sizes due to limitations in medical supplies. Contents of the invention [0004] Purpose of the invention: In order to provide a more effective variable-diameter catheter and a variable-diameter method, see the multiple substantive technical effects in the specific implementation part for specific purposes. [0005] In order to achieve the above object, the present invention takes the following technical solutio...
