CN201516239U - Multi-cavity reducing pipe - Google Patents

Abstract

The utility model discloses a multi-cavity reducing pipe and aims at providing a reducing pipe which can be connected with a plurality of guiding pipes externally. After plastic master batches are added into an extrusion machine, and a multi-cavity pipe is primarily prepared through placing different multi-cavity pipe dies on the machine head position of the extrusion machine. The extrusion frequency or the traction speed can be changed through computer intelligent control to prepare shaped multi-cavity reducing pipes. The extrusion frequency forms direct ratio with the inner and outer diameter of a pipe body in the extrusion process. The traction speed and inner and outer diameter of the pipe body form inverse ratio in the traction process.

Description

A kind of multi-cavity reducer pipe

Technical field

This utility model relates to technical field of medical instruments, particularly relates to a kind of multi-cavity reducer pipe.

Background technology

Medical catheter is to use medical apparatus and instruments very widely in the clinical treatment work.Wherein, reducer pipe be a kind of in the medical catheter of external diameter even variation, the suitable change of internal diameter is big or diminish, and adapts to the purpose that other conduits insert to reach.But in therapeutic process, need sometimes multiple medicine is transported in the human body simultaneously by reducer pipe, these medicines can not mix input again, at this moment just need a kind of multi-cavity reducer pipe that inserts a plurality of conduits to satisfy the demand.Tube material comprises PVC, PU, PA, PP, fluoroplastics etc.

Summary of the invention

This utility model provides a kind of simple in structure in order to solve the deficiency on the prior art, is applicable to connect a plurality of conduits, satisfies the multi-cavity reducer pipe that uses multiple medicine simultaneously.

This utility model has adopted following technical scheme: catheter tube includes multi-cavity, and the diameter in each chamber can increase or dwindle uniformly in this conduit external diameter and the pipe.

Compare with existing product, the utility model has the advantages that:

1, multiple functional.Both can make other transfusion catheters carry medicine, and also can satisfy a plurality of medicines and import simultaneously in the human body, and make therapeutic process convenient by directly inserting reducer pipe.

2, produce simply.Place multi-lumen mold in extruder after, the variation of extruding frequency and hauling speed by computer control extruder promptly can be made into the multi-cavity reducer pipe.

Description of drawings

Fig. 1 is the side view before this utility model multi-cavity reducer pipe does not have cutting;

Fig. 2 is the in type side view in this utility model multi-cavity reducer pipe cutting back;

Fig. 3 is the profile of this utility model multi-cavity reducer pipe.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in detail:

Shown in Figure 1 is the multi-cavity reducer pipe before the cutting after extruding, and appearance is one and evenly becomes conduit big or that diminish, and the diameter of multi-cavity evenly becomes big with external diameter or diminishes in the pipe.

Shown in Figure 2 be the cutting after the multi-cavity reducer pipe, the end that external diameter is big can connect a plurality of conduits, is convenient to carry multiple medicine.Along with reducer pipe attenuates, the other end that external diameter is little can be used for the conditional human body of body external diameter thickness.

Shown in Figure 3 is multi-cavity reducer pipe profile, and what this figure showed is five cavitys, can make the multi-cavity reducer pipe that contains different cavitys as required.

Claims (1)

1. a multi-cavity reducer pipe is characterized in that body includes multi-cavity, and the diameter in each chamber increases uniformly or dwindles in conduit external diameter and the pipe.
