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

A kind of variable diametered duct and change routing method
Technical field
The present invention relates to medical field, more particularly to a kind of variable diametered duct and change routing method.
Background technology
The defect of prior art is:
Different people physiological conditions are different, and the thickness of its tracheae is different, but the pipeline of hospital is all standard, its thickness without Method changes, and patient is very uncomfortable sometimes, there is foreign body sensation.Sometimes due to the limitation of medical material, conduit can not be equipped with completely A series of pipeline of sizes.
The content of the invention
The purpose of invention：In order to provide a kind of effect preferably variable diametered duct and change routing method, specific purposes are shown in specifically Multiple substantial technological effects of implementation section.
In order to reach as above purpose, the present invention is adopted the following technical scheme that：
Scheme one：
A kind of variable diametered duct, it is characterised in that comprising catheter body, the catheter body includes soft section and hard Part, using one of following scheme:A. the soft section and hard portions are alternately distributed so that overall pipe diameter can Become；B. the soft section and hard portions can constitute pipeline entirety, and soft section and hard portions are respectively arc.
Further technical scheme of the invention is that the hard portions tundish of the hard arc contains a soft connection Point.
Further technical scheme of the invention is but that the hard portions and soft section are a kind of material hard portions Thickness causes the convenient folding of soft section more than the thickness for causing soft section.
Further technical scheme of the invention is that the hard portions and soft section are seamlessly connected one by heat seal Rise.
Further technical scheme of the invention is that groove is included on the outer wall of the hard portions, and medicine can be placed in groove Thing.
Further technical scheme of the invention is that the catheter body end includes a rubber sleeve, and the rubber sleeve is circle Shape, its section includes groove, and groove can clamp conduit mouth.
Scheme two：
A kind of change routing method of variable diametered duct, it is characterised in that using as above arbitrarily described conduit, by the soft of conduit Matter part and hard portions partial folds, it is soft to fold so that overall pipe diameter changes.
Using the present invention of as above technical scheme, have the advantages that relative to prior art：Using as above any institute The conduit stated, it is soft to fold by the soft section of conduit and hard portions partial folds so that overall pipe diameter changes Become.Suitable child uses, and also is adapted for adult's use, and people will not be allowed to have foreign body sensation, and feeling ill, it is a little bit smaller that just caliber is folded.
Description of the drawings
In order to further illustrate the present invention, it is further illustrated below in conjunction with the accompanying drawings：
Fig. 1 is the schematic diagram of inventive structure embodiment one；
Fig. 2 is the structural representation of inventive embodiments two；
Fig. 3 is the structural representation of embodiment three；
Wherein：1. hard portions；2. soft section；3. soft gap；4. hard gap；5. soft tie point.
Specific embodiment
Embodiments of the invention are illustrated below in conjunction with the accompanying drawings, embodiment is not construed as limiting the invention：
Scheme one：
A kind of variable diametered duct, it is characterised in that comprising catheter body, the catheter body includes soft section and hard Part, using one of following scheme:A. the soft section and hard portions are alternately distributed so that overall pipe diameter can Become；B. the soft section and hard portions can constitute pipeline entirety, and soft section and hard portions are respectively arc.Scheme A is embodiment one；Option b is embodiment two.Substantive technique effect and its realize process that the technical scheme at this place is played For as follows：It is soft to fold by the soft section of conduit and hard portions partial folds using as above arbitrarily described conduit, So that the pipe diameter of entirety changes.Suitable child uses, and also is adapted for adult's use, and people will not be allowed to have foreign body sensation, feels ill Just caliber is folded a little bit smaller.
With reference to Fig. 3, embodiment three, the hard portions tundish of the hard arc contains a soft tie point.This place Substantive technique effect and its realize that process is as follows that technical scheme is played：Can conveniently adjust whole using soft connecting tube The radian of body.More convenient reducing.
The hard portions and soft section are a kind of material but hard portions thickness is more than the thickness for causing soft section Degree causes the convenient folding of soft section.Substantive technique effect that the technical scheme at this place is played and its realize process be as Under：It is, a kind of material that hard cannot fold using the benefit of this kind of pattern, than relatively thin just convenient folding, overall reducing is more square Just, slitless connection is realized.Polyvinyl chloride can such as be adopted.
Together with the hard portions and soft section are seamlessly connected by heat seal.The reality that the technical scheme at this place is played The technique effect of matter and its realize that process is as follows：The heat seal at this place is also a kind of specific combination, can be conveniently overall The change of diameter.
Groove is included on the outer wall of the hard portions, can holding medicine in groove.What the technical scheme at this place was played Essence technique effect and its realize that process is as follows：It is also a kind of process of dispenser when putting pipe.
The catheter body end includes a rubber sleeve, and the rubber sleeve is circle, and its section includes groove, and groove can be pressed from both sides Hold conduit mouth.Substantive technique effect and its realize that process is as follows that the technical scheme at this place is played：Using this kind of structure, Can facilitate diameter is safeguarded in end, after clamping, diameter can be maintained, and remove rubber sleeve, can just change diameter.
In a creative way, each effect of the above is individually present, moreover it is possible to complete the combination of the above results with a nested structure.
It is clear that the technique effect that above structure is realized is realized, discounting for additional technical scheme, this patent title is also It can be a kind of conduit.Part details not shown in figure.
It should be noted that multiple schemes that this patent is provided include the basic scheme of itself, it is separate, not mutually Restriction, but it can also be mutually combined in the case where not conflicting, and reach multiple effects and realize jointly.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of this area Personnel should be recognized that the present invention is not restricted to the described embodiments, and simply this is illustrated described in above-described embodiment and specification Bright principle, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes Both fall within claimed scope with improving.
