Technical Field
The invention relates to the field of medical treatment, in particular to a diameter-variable catheter and a diameter-variable method.
Background
The defects of the prior art are as follows:
different people's physiology condition is different, and its trachea thickness is different, but the pipeline of hospital all is the standard, and its thickness can't change, and patient sometimes can be very uncomfortable, has the foreign body sensation. Sometimes catheters cannot be fitted with a full range of sizes of tubing due to medical supplies limitations.
Disclosure of Invention
The purpose of the invention is as follows: in order to provide a variable diameter catheter and a variable diameter method with better effect, the specific purpose is to see a plurality of substantial technical effects of the specific implementation part.
In order to achieve the purpose, the invention adopts the following technical scheme:
the first scheme is as follows:
a variable-diameter catheter is characterized by comprising a catheter body, wherein the catheter body comprises a soft part and a hard part, and one of the following schemes is adopted, namely A, the soft part and the hard part are alternately distributed, so that the diameter of the whole pipeline is variable; B. the soft portion and the hard portion can form an integral pipeline, and the soft portion and the hard portion are respectively arc-shaped.
The invention further adopts the technical scheme that the middle of the hard arc-shaped hard part comprises a soft connecting point.
The invention further adopts the technical scheme that the hard part and the soft part are made of one material, but the thickness of the hard part is larger than that of the soft part, so that the soft part is convenient to fold.
The invention further adopts the technical scheme that the hard part and the soft part are connected together in a seamless mode through heat sealing.
The invention further adopts the technical scheme that the outer wall of the hard part comprises a groove, and medicines can be placed in the groove.
The invention has the further technical scheme that the end part of the catheter body comprises a rubber sleeve, the rubber sleeve is circular, the cross section of the rubber sleeve comprises a groove, and the groove can clamp the catheter port.
Scheme II:
a diameter changing method of a diameter changeable conduit is characterized in that the conduit is utilized, the soft part and the hard part of the conduit are partially folded, the soft part can be folded, and the caliber of the whole pipeline is changed.
Compared with the prior art, the invention adopting the technical scheme has the following beneficial effects: with the catheter as described above, the soft portion and the hard portion of the catheter are partially folded, and the soft portion is folded, so that the overall pipe diameter is changed. The pipe diameter folding device is suitable for children and adults, does not cause foreign body sensation, and can be folded slightly when people feel uncomfortable.
Drawings
To further illustrate the present invention, further description is provided below with reference to the accompanying drawings:
FIG. 1 is a schematic diagram of an embodiment of the inventive structure;
FIG. 2 is a schematic structural diagram of a second embodiment of the present invention;
FIG. 3 is a schematic view of a third embodiment;
wherein: 1. a hard portion; 2. a soft portion; 3. a soft gap; 4. a hard gap; 5. a soft connection point.
Detailed Description
Embodiments of the present invention will now be described with reference to the accompanying drawings, which are not intended to limit the invention:
the first scheme is as follows:
a variable-diameter catheter is characterized by comprising a catheter body, wherein the catheter body comprises a soft part and a hard part, and one of the following schemes is adopted, namely A, the soft part and the hard part are alternately distributed, so that the diameter of the whole pipeline is variable; B. the soft portion and the hard portion can form an integral pipeline, and the soft portion and the hard portion are respectively arc-shaped. Scheme a is example one; scheme B is example two. The technical scheme of the invention has the following substantial technical effects and the realization process: with the catheter as described above, the soft portion and the hard portion of the catheter are partially folded, and the soft portion is folded, so that the overall pipe diameter is changed. The pipe diameter folding device is suitable for children and adults, does not cause foreign body sensation, and can be folded slightly when people feel uncomfortable.
With reference to fig. 3, in the third embodiment, the hard portion of the hard arc includes a soft connection point in the middle. The technical scheme of the invention has the following substantial technical effects and the realization process: adopt soft connecting pipe can conveniently adjust holistic radian. The diameter can be changed more conveniently.
The hard portion and the soft portion are of one material but the thickness of the hard portion is greater than the thickness of the soft portion so that the soft portion is conveniently folded. The technical scheme of the invention has the following substantial technical effects and the realization process: the mode has the advantages that one material is hard and cannot be folded, the material is thinner and is convenient to fold, the whole diameter is more convenient to change, and seamless butt joint is realized. For example, polyvinyl chloride may be used.
The hard part and the soft part are connected together in a seamless way through heat seal. The technical scheme of the invention has the following substantial technical effects and the realization process: the heat seal is also a specific combination mode, and the change of the whole diameter can be facilitated.
The outer wall of the hard part comprises a groove, and medicines can be placed in the groove. The technical scheme of the invention has the following substantial technical effects and the realization process: when the tube is put, the process of drug application is also realized.
The end part of the catheter body comprises a rubber sleeve, the rubber sleeve is circular, the cross section of the rubber sleeve comprises a groove, and the groove can clamp the catheter port. The technical scheme of the invention has the following substantial technical effects and the realization process: by adopting the structure, the diameter can be conveniently maintained at the end part, after clamping, the diameter can be maintained, and the diameter can be changed by removing the rubber sleeve.
Creatively, the above effects exist independently, and the combination of the above results can be completed by a set of structure.
The technical effect that above structure realized realizes clearly, if do not consider additional technical scheme, this patent name can also be a pipe. Some details are not shown in the figures.
It should be noted that the plurality of schemes provided in this patent include their own basic schemes, which are independent of each other and are not restricted to each other, but they may be combined with each other without conflict, so as to achieve a plurality of effects.
