Description

Double-bow-head connecting pipe

Technical Field

The utility model relates to the field of medical treatment, especially a double-bow head connecting pipe.

Background

Hemodialysis is one of the kidney replacement treatment modes of patients with acute and chronic renal failure. The blood and electrolyte solution (dialysate) with similar concentration of organism are arranged inside and outside one hollow fiber by draining the blood in vivo to the outside of the body through a dialyzer consisting of a plurality of hollow fibers, and the material exchange is carried out by dispersion/convection, thereby removing the metabolic waste in the body and maintaining the balance of electrolyte and acid-base; at the same time, the excess water in the body is removed, and the purified blood is returned to the whole process. The existing connecting pipe only has the drainage function, can not inject the flushing fluid containing anti-inflammatory drugs at the same time, has low anti-inflammatory efficiency, and can easily cause secondary bacterial pollution due to the direct communication with the blood return line and the blood backflow.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is not enough to above-mentioned prior art. Provided is a double-bow-head connection tube which can facilitate the injection of an anti-inflammatory drug-containing rinse solution and can effectively prevent the backflow of blood.

In order to achieve the above object, the utility model adopts the following technical scheme:

a double-bow connecting tube, characterized by comprising:

the drainage main pipe is a pipeline with two sealed ends and uniform wall thickness, the upper end of the drainage main pipe is a main inlet end, and the lower end of the drainage main pipe is an outlet end;

the drainage side pipe is a pipe with uniform wall thickness, at least 1 pipe is arranged, one end of the drainage side pipe is communicated with the drainage main pipe, the other end of the drainage side pipe is a side inlet end, and the end face of the side inlet end is sealed;

and the one-way valve is fixedly arranged in the drainage main pipe, so that the liquid in the pipe flows to the main inlet end and faces to the outlet end.

Preferably, the main inlet end, the outlet end and the side inlet end are provided with a bow.

Preferably, the drainage side pipe is connected with the drainage main pipe in a Y shape.

Preferably, the one-way valve is disposed in the bow of the outlet end.

Preferably, 1 drainage side tube is arranged.

The utility model has the advantages that:

1. the check valve is arranged, so that the backflow cannot be generated, and the blood backflow risk and the machine pollution are avoided.

2. All the pipelines are communicated without separation, and the whole process is closed to safely return the blood in the extracorporeal circulation pipeline, so that accidents such as secondary pollution and the like are prevented, and the automatic operation is realized.

3. The blood return side and the dialyzer side are not separated, so that the probability of secondary bacterial pollution and cross infection is reduced.

Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1, the utility model discloses a double-bow connecting pipe, its characterized in that includes:

the drainage main pipe 110 is a pipeline with two sealed ends and uniform wall thickness, the upper end of the drainage main pipe is a main inlet end 111, and the lower end of the drainage main pipe is an outlet end 112;

the drainage side pipe 120 is a pipe with uniform wall thickness, 1 pipe is arranged, one end of the drainage side pipe is communicated with the drainage main pipe, the other end of the drainage side pipe is a side inlet end 121, and the end face of the side inlet end 121 is sealed;

and the check valve 130 is fixedly arranged in the main drainage pipe 110, so that the liquid in the pipe flows to the main inlet end 111 towards the outlet end 112.

In this embodiment, the main inlet 111, the outlet 112, and the side inlet 121 are provided with a bow 140.

In this embodiment, the drainage side tube 120 is connected to the drainage main tube 110 in a Y-shape.

In this embodiment, the one-way valve 130 is disposed within the bow 140 of the outlet end 112.

Introduction of principle (as shown in fig. 1):

during dialysis, there are two blood circulation systems:

in vivo blood circulation system 300: heart 310 → vein 320 → lung 330 → artery 340 → heart 310 → … …

Dialysis blood circulation system: dialyzer 200 → main inlet end 111 → main drainage tube 110 → one-way valve 130 → outlet end 112 → vein 320 → lung 330 → artery 340 → circuit connection tube → dialyzer 200 → … …

When it is desired to inject a flushing fluid containing an anti-inflammatory agent, the injection may be performed through the inlet end 121.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art.
