Abstract
The invention discloses a three-cavity catheter which comprises a catheter body. Three cavities which are not communicated with one another are reserved in the catheter body and include a main cavity on the center line of the catheter body and a first auxiliary cavity and a second auxiliary cavity which cover the periphery of the main cavity. The three-cavity catheter is safe and reliable, and can be used for successfully delivering and identifying fluids having the requirement on constant temperature or light proofing during use, and accordingly a desired constant-temperature or light-proof effect can be achieved. Besides, the three-cavity catheter is low in cost, the purpose of delivering and recognizing the fluids having the requirement on constant temperature or light proofing can be achieved by connecting the three-cavity catheter to the different fluids, and conventional complicated processes for keeping temperature constant mechanically are reduced.
Description
Technical field
The present invention relates to a kind of medical catheter, particularly relate to a kind of three cavities conduit pipe.
Background technology
At present, a lot of clinical uses or instrumentation need to be carried high temperature, cooling or lucifuge liquid, if but do not have a kind of pipeline that can keep constant temperature, can cause liquid in course of conveying, to lose effect, do not reach the expection purpose, bring a lot of inconvenience for operation or use.
Summary of the invention
Goal of the invention: the present invention is in order to solve the deficiencies in the prior art, provides a kind of and is convenient to identify, precision is high, have the three cavities conduit pipe of concentricity inner chamber.
The technical solution used in the present invention: a kind of three cavities conduit pipe, comprise body, comprise three not connected cavitys in the described body, be respectively the main chamber that is positioned at the body position of center line, the first secondary chamber that is wrapped in periphery, described main chamber and the second secondary chamber.
As optimization, described main chamber, the first secondary chamber and the second secondary chamber cavity length equate, and be isometric with described body.
As optimization, the cross section in described main chamber is circular or many rhombuses.
As optimization, the cross section in the described first secondary chamber and the second secondary chamber is semilune.
As optimization, be respectively equipped with corresponding the first colo(u)r streak and the second colo(u)r streak on the cavity wall in the described first secondary chamber and the second secondary chamber, described the first colo(u)r streak is two development colo(u)r streak or colo(u)r streaks that do not develop that color is different with the second colo(u)r streak.
As optimization, be provided with two between the described first secondary chamber and the second secondary chamber and strengthen directly linking to each other with described inboard wall of tube body, be used for the supporting tube body, guarantee concentricity and the body circularity in main chamber.
As optimization, described body is that the caliber of described body is 0.5MM-10MM by 45A-75D medical macromolecular materials or the developing material ray that can not penetrate with X-ray according to actual use.
Three cavities conduit pipe of the present invention is to be made through calculating melt material flow pressure and conduit molding internal stress by the handpiece body of extruder particular design and mould, by coextrusion finally on each crescent moon tube wall injection lines form.During use, main cavity is carried main liquid, and high temperature, cooling or lucifuge liquid are carried in the first secondary chamber and the second secondary chamber.According to requirements, can control the exocoel temperature of liquid, or add lucifuge liquid, reach intracavity liquid temperature or lucifuge requirement.According to requirements, can in three chambeies, carry different liquids.Judge the purposes in each chamber according to different colours colo(u)r streak on the cavity wall in the first secondary chamber and the second secondary chamber.
Beneficial effect: safe and reliable, successfully solved the conveying and the identification that in use need constant temperature or lucifuge liquid, can reach expection constant temperature or lucifuge phase effect; Product cost is low, as long as a conduit is connected on respectively on the different liquid and just can realizes above problem, has reduced the loaded down with trivial details flow process of tradition by apparatus constant temperature, has saved cost, has improved work efficiency, reaches the purpose of instructions for use.
