Abstract
The utility model discloses a high-hardness uniformly-plasticized catheter, which belongs to the technical field of catheters and comprises a catheter body, wherein the catheter body is formed by combining a PVC outer tube and a PVC inner tube, the PVC outer tube is wrapped on the outer side of the PVC inner tube, the PVC outer tube and the PVC inner tube are equal in length, the inner layer adopts the PVC inner tube to contact liquid medicine, solution and blood, so that hidden danger that a plasticizer in PVC can be prevented from migrating into the body of a patient can be avoided, the safety of the patient is higher, the outer layer adopts the PVC outer tube to inherit the excellent bonding property of a PVC material, the assembly efficiency is improved, and the leakage rate between a pipeline and a joint is reduced.
Description
Technical Field
The utility model relates to a catheter, in particular to a catheter with high hardness and uniform plasticization, and belongs to the technical field of catheters.
Background
Adopt its resilience of TPE pipe poor, easy kink leads to the problem of pipeline jam when adopting single PVC pipe can appear contacting to lead liquid medicine, solution and blood among the prior art, for this design a high rigidity plastify even pipe solve above-mentioned problem.
SUMMERY OF THE UTILITY MODEL
The main purpose of the utility model is to provide a high-hardness catheter with uniform plasticization, the inner layer adopts a PVC inner tube to contact liquid medicine, solution and blood, so that the hidden danger that plasticizer in PVC migrates into the body of a patient can be avoided, the safety to the human body is higher, the outer layer adopts a PVC outer tube to inherit the excellent bonding performance of PVC materials, the assembly efficiency is improved, the leakage rate between a pipeline and a joint is reduced, and the defects that a single TPE pipeline has poor resilience and is easy to kink to cause pipeline blockage can be improved.
The purpose of the utility model can be achieved by adopting the following technical scheme:
the utility model provides a pipe that high rigidity plastify is even, includes the body, the body is formed by PVC outer tube and PVC inner tube combination, wherein the PVC outer tube parcel is in the outside of PVC inner tube, the PVC outer tube with length such as PVC inner tube, purple color masterbatch has evenly been laid in the outside of PVC outer tube.
Preferably, the hardness of the PVC outer pipe is 68A.
Preferably, the weight ratio of the PVC outer pipe to the PVC inner pipe is 1: 2.
preferably, the pipe body is produced and prepared in a hundred thousand grade clean workshop.
Preferably, the inner diameter of the PVC inner pipe is between 2.85 and 2.95mm, and the outer diameter of the PVC outer pipe is between 3.95 and 4.05 mm.
The utility model has the beneficial technical effects that:
according to the high-hardness uniform-plasticization catheter provided by the utility model, the inner layer adopts the PVC inner tube to improve the assembly efficiency and reduce the leakage rate between the pipeline and the joint, the defects that a single TPE pipeline has poor resilience and is easy to kink to cause pipeline blockage can be overcome, the purple color master batch is uniformly paved on the outer side of the PVC outer tube, so that clinical discrimination can be realized through color, and the purple pipeline is convenient for distinguishing infusion pipelines.
Drawings
FIG. 1 is a side view of a preferred embodiment of a high durometer, uniformly plasticized catheter in accordance with the present invention;
fig. 2 is a front view of a preferred embodiment of a high durometer, uniformly plasticized catheter in accordance with the present invention.
In the figure: 1-PVC outer pipe, 2-PVC inner pipe and 3-pipe body.
Detailed Description
In order to make the technical solutions of the present invention more clear and definite for those skilled in the art, the present invention is further described in detail below with reference to the examples and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
As shown in fig. 1-2, the catheter with high hardness and uniform plasticization provided in this embodiment includes a catheter body 3, the catheter body 3 is formed by combining a PVC outer tube 1 and a PVC inner tube 2, wherein the PVC outer tube 1 is wrapped around the outside of the PVC inner tube 2, the PVC outer tube 1 and the PVC inner tube 2 have the same length, and a purple color masterbatch is uniformly laid on the outside of the PVC outer tube 1.
The inner layer adopts PVC inner tube 2 can improve single TPE pipeline resilience difference, easily kinks the shortcoming that leads to the pipeline to block up.
In this embodiment, the PVC outer pipe 1 has a hardness of 68A.
In this embodiment, the weight ratio of the PVC outer pipe 1 to the PVC inner pipe 2 is 1: 2.
in this embodiment, the tubular body 3 is produced in a hundred thousand class clean room.
In this embodiment, the inner diameter of the PVC inner pipe 2 is 2.85-2.95mm, and the outer diameter of the PVC outer pipe 1 is 3.95-4.05 mm.
The above are only further embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and its concept within the scope of the present invention.
