Abstract
The utility model relates to a medical pipeline which is extruded by high polymer material and developer, which comprises a pipeline and a developer; wherein, the diameter of the developer is smaller than the wall thickness of the pipeline; the developer does not contact with the inner wall and outer wall of the pipeline, or can only contact with the outer wall of pipeline, thereby the integrality of pipeline wall is ensured, even if the pipeline is used for long time, the pipeline is uneasy to break. The utility model has the advantages of simple structure, good developing performance, ensured developing effect and ensured safe and reliable operation; thus the utility model is widely used for medical nostril-gastrointestinal tube, intestinal intubatton, drainage tube, conduit in blood vessel and intervention therapy pipeline.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of medical tubing that adopts macromolecular material and developing agent coextrusion mold.
Background technology
The medical apparatus and instruments pipeline that much needs developing technique is arranged, as Nasal gastrointestinal tube, intestinal intubate, drainage tube, catheter in blood vessel and interventional therapy pipeline etc. in the clinical use; At present, the pipeline of these band developing agents adopts macromolecular material and developing agent coextrusion mold usually, the diameter of its developing agent is more than or equal to the wall thickness of pipeline, so the tube wall inner and outer wall of the outer contour of development line and pipeline all connects, because developing agent is different with the pipeline material, only depend on physical action to press together, the pipeline of this communicating structure is long-time to use easy contact surface from two kinds of materials to rupture.
Summary of the invention
The purpose of this utility model is to solve above-mentioned prior art problem and a kind of integrity that guarantees tube wall is provided, and difficult the fracture used more safe and reliable macromolecular material and developing agent coextrusion mold medical tubing.
The technical solution adopted in the utility model: a kind of macromolecular material and developing agent coextrusion mold medical tubing, comprise pipeline, developing agent, the diameter of described developing agent is less than the pipe thickness of pipeline.
Described developing agent is positioned at tube wall inside, and the inner and outer wall of the tube wall of developing agent and pipeline is all contactless.
Described developing agent is positioned at the outside of tube wall inside, and developing agent contacts with the outer wall of tube wall, and is contactless with the inwall of tube wall.
Described developing agent shape of cross section is circular, oval, semicircle.
Described pipeline material is medical transparent polyvinyl chloride or medical transparent polyurethane, and the developing agent material is a barium sulfate.
Advantage of the present utility model is:
1. the diameter of developing agent makes developing agent not contact the tube wall inner and outer wall of pipeline less than the pipe thickness of pipeline, or only contacts the outer wall of tube wall and do not contact the inwall of tube wall, has guaranteed the integrity of tube wall, even the life-time service pipeline also is difficult for rupturing;
2. this utility model is simple in structure, and developing performance is good, both can guarantee development effect, can guarantee that again use is more safe and reliable, can be widely used in medical Nasal gastrointestinal tube, intestinal intubate, drainage tube, catheter in blood vessel and interventional therapy pipeline etc.

The specific embodiment
Embodiment 1
Consult Fig. 1, shown in Figure 2, a kind of macromolecular material and developing agent coextrusion mold medical tubing comprise pipeline 1, developing agent 2 etc.; Its pipeline 1 is selected medical transparent polyvinyl chloride or medical transparent polyurethane material for use, developing agent 2 is selected the barium sulfate material for use, adopt two extruders to supply with different melting charges respectively, amount at a composite machine head internal exchange and to extrude, the macromolecular material of different qualities is merged in extrusion each other, obtain the pipeline of double-colored difunctional band development line.
The diameter of described developing agent 2 is less than the thickness of the tube wall 101 of pipeline 1, developing agent 2 is positioned at tube wall 101 inside, developing agent 2 does not all contact with the inner and outer wall of the tube wall 101 of pipeline 1, has effectively guaranteed the integrity of tube wall 101, and life-time service can not make pipeline 1 rupture yet; Described developing agent 2 shape of cross sections are circle, ellipse, semicircle etc.
Consult shown in Figure 3ly, described developing agent 2 is positioned at the outside of tube wall 101 inside, and 2 outer walls with tube wall 101 of developing agent contact, and contactless with the inwall of tube wall 101, can guarantee that the inwall of tube wall 101 does not rupture, and guarantees the safety of using.All the other structures are with embodiment 1.
