Abstract

The utility model discloses an anti-bending multi-cavity telescoping pipe with features of simple structure, safety and reliability, which is suitable for connecting a plurality of ducts and simultaneously uses a variety of medicines. A plurality of cavities are arranged in the anti-bending multi-cavity telescoping pipe. The outer diameter of the ducts and the diameter of the cavities in the pipe uniformly increases or decreases. The pipe is composed of an inner layer plastic pipe, a reinforced weaving net and an outer layer plastic pipe which are arranged in turn from inside to outside. The pipe has the anti-bending function. The anti-bending multi-cavity telescoping pipe has complete function, is conveniently operated, makes the other transfusion ducts transfer the medicine by directly inserting the transfusion dusts into the telescoping pipe and also simultaneously transfers various medicines into the human body, thus the treatment process is more convenient. The pipe has the anti-bending function and medicines of different densities are simultaneously transferred into the appointed parts by the pipe, so as to prevent the medicine treatment accident due to pipe extrusion and bending and increase the safety.

Description

Anti-folding multi-cavity reducer pipe

Technical field

This utility model relates to a kind of medical catheter, particularly relates to a kind of anti-folding multi-cavity reducer pipe.

Background technology

Medical catheter is to use medical apparatus and instruments very widely in the clinical treatment work.Wherein, the multi-cavity reducer pipe is that a kind of body has a plurality of chambeies, can insert a plurality of conduits, the multiple medicine that can not mix input is transported in the human body through reducer pipe simultaneously, and the medical catheter of external diameter even variation.The hardness unanimity and the body of existing multi-cavity reducer pipe inner chamber are softer, and be withstand voltage not enough, and the different pharmaceutical of input is inconsistent owing to density simultaneously in the use; Often make body extruding, distortion; Even bending, cause medicine accurately not import, very easily cause malpractice.

Summary of the invention

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

This utility model has adopted following technical scheme: anti-folding multi-cavity reducer pipe; Different multi-lumen molds is placed at head position through at extruder; And through Computerized intelligent control, change and extrude frequency or hauling speed, make multi-cavity reducer pipe inner layer plastic tube; On multi-cavity reducer pipe inner layer plastic tube, compile out the reinforcement mesh grid continuously then, in mesh grid, extrude outer layer plastic tube again and process.Wherein, outer and inner layer plastic tube is processed by medical plastic, strengthens mesh grid and is processed by tinsel or cellosilk.Should include multi-cavity by anti-folding multi-cavity reducer pipe body, and the diameter in each chamber increases uniformly or dwindles in conduit external diameter and the pipe, body by inner layer plastic tube, strengthen mesh grid and outer layer plastic tube is formed from inside to outside successively, body has anti-folding function.

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

1, multiple functional, easy and simple to handle.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 through directly inserting reducer pipe.

2, safe and reliable.Contain the reinforcement mesh grid in the body, its withstand voltage properties is significantly promoted, guarantee that the medicine of the different densities of input all can smooth and easyly arrive appointed part through body simultaneously, prevent the malpractice that causes because of body extruding, bending.

Description of drawings

Fig. 1 is the sketch map of the anti-folding of this utility model multi-cavity reducer pipe;

Fig. 2 is the wherein product profile in a chamber of the anti-folding 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 be the cutting after anti-folding 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 2 is the wherein product profile in a chamber of anti-folding multi-cavity reducer pipe; Wherein, The 1st, inner layer plastic tube, the 2nd, strengthen mesh grid, the 3rd, outer layer plastic tube; Strengthen mesh grid 3 and have good withstand voltage properties, guarantee that the variety classes of input simultaneously, the medicine of different densities all can smooth and easyly arrive appointed part through body.What this figure showed is five cavitys, can process the multi-cavity reducer pipe that contains different cavitys as required.

Claims

1. an anti-folding 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; Body is made up of inner layer plastic tube, reinforcement mesh grid and outer layer plastic tube from inside to outside successively, and body has anti-folding function.

2. a kind of anti-folding multi-cavity reducer pipe according to claim 1 is characterized in that the conduit reducing is to make through the variation of extruding frequency or hauling speed in the extrusion, and the conduit multi-cavity makes through placing multi-lumen mold in the extruder.

3. a kind of anti-folding multi-cavity reducer pipe according to claim 1; It is characterized in that; The anti-folding of body function is to reach through the reinforcement mesh grid in inside and outside layer plastic tube, strengthens mesh grid and is wrapped on the inner layer plastic tube, and outer layer plastic tube is wrapped in to be strengthened in the mesh grid; Outer and inner layer plastic tube is processed by medical plastic, strengthens mesh grid and is processed by tinsel or cellosilk.
