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 whole process of purified blood reinfusion is called hemodialysis.

At present, a blood pump is generally adopted as a power source for blood to flow in vitro, small blood cells in the blood flowing in vitro can be damaged to form blood coagulation, and part of hollow fibers can block the blood coagulation to cause the blockage of a pipeline, so that certain potential safety hazard is realized, and the on-off condition of the pipeline needs to be fed back.

Detailed Description

The present invention is further described with reference to the following embodiments, which are not intended to limit the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Example 1

The liquid path on-off feedback device for the hemodialysis equipment comprises a first pipeline joint 1 and a second pipeline joint 6, wherein an expansion membrane 9 is arranged between the first pipeline joint 1 and the second pipeline joint 6, the expansion membrane 9 is of a tubular structure, and two ends of the expansion membrane are respectively sleeved on the end parts of the first pipeline joint 1 and the second pipeline joint 6.

First pipeline connects 1 and second pipeline to connect 6 and establishes ties on the dialysis pipeline as the connecting portion with the pipeline, and inflation membrane 9 can adopt medical silica gel to make, and it has flexibility and can receive the pressure inflation, and when the pipeline appeared blockking up, the pressure increase in the pipeline will make inflation membrane 9 inflation, can feed back the jam degree of pipeline through the inflation degree.

Example 2

The present embodiment further describes the technology, including the outer casing 2 and the sealing cover 5, the outer casing 2 and the sealing cover 5 are fastened to form a cavity structure, the expansion film 9 is disposed in the cavity structure, and the first pipeline joint 1 and the second pipeline joint 6 respectively penetrate through the outer casing 2 and the sealing cover 5 to connect with two ends of the expansion film 9.

The outer shell 2 and the sealing cover 5 can be made of dialysis materials, so that the form of the expansion membrane 9 can be visually observed, the outer shell 2 and the sealing cover 5 form a supporting structure of the first pipeline connector 1 and the second pipeline connector 6, and the expansion membrane 9 is prevented from being bent in the using process to influence the prompting effect.

Example 3

In this embodiment, the side wall of the outer casing 2 is connected with a first terminal 3 and a second terminal 4 in a penetrating manner, the first terminal 3 is connected with a spring plate 11, and the spring plate 11 and the second terminal 4 are in a separated state in a natural state.

First terminal 3 and second terminal 4 are installed respectively on shell body 2, first terminal 3 and second terminal 4 can establish ties on audible-visual annunciator, when the jam appears in the pipeline, pressure increase in the pipeline will make inflation membrane 9 inflation, expand the extension through the outside inflation of inflation membrane 9 and will promote shell fragment 11, make shell fragment 11 and second terminal 4 contact, and then make first terminal 3 and second terminal 4 switch on, as audible-visual annunciator's control switch, make audible-visual annunciator work, and then realize feeding back through audible-visual annunciator the jam condition to the pipeline.
