Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] Such as figure 1 , figure 2 As shown, the one-way valve of the present invention is composed of a first joint 1, a second joint 2 and a diaphragm 3, wherein the material of the first and second joints 1 and 2 is preferably plastic, and it can also be plastic by injection molding. Metal or other suitable materials, and the material of the diaphragm 3 is medical rubber. The first and second joints 1 and 2 are all pipe structures, and a first connecting seat 1a is integrally formed at one end of the first joint 1 close to the second joint 2, and the outer contour of the first connecting seat 1a is circular , the inner cavity of the first connecting seat 1a is conical, the smallest end of the conical shape communicates with the inner hole of the tube body part of the first joint 1, the largest end of the conical shape is open, and is located on the end ...

Abstract

The invention discloses a one-way valve for a hemodialysis machine, comprising a first joint (1) and a second joint (2), wherein both the first joint (1) and the second joint (2) are through-pipe structures; the opposite ends of the first joint (1) and the second joint (2) are respectively provided with a first connecting seat (1a) and a second connecting seat (2a), the first joint (1) and the second joint (2) are fixed together through the two connecting seats (1a, 2a), and the inner cavities of the first connecting seat (1a) and the second connecting seat (2a) form the valve cavity of the one-way valve; and the valve cavity is internally provided with a diaphragm (3) limited by the cavity wall of the first connecting seat (1a) and a rib plate (2b) inside the second connecting seat (2a).The one-way valve has simple structure, easy processing and manufacture, low cost, good reliability and high sensitivity, and because the one-way valve is made of medical rubber and plastics, the one-way valve has good biological property and cannot pollute medical fluid.

Description

technical field [0001] The invention relates to a hemodialysis machine, in particular to a one-way valve on the hemodialysis machine. Background technique [0002] The one-way valve is an important part of the hemodialysis machine, which plays a role in controlling the one-way flow of liquid. At present, the one-way valves used in hemodialysis machines are generally made of metal springs. On the one hand, they are easy to rust, and metal ions are easy to contaminate medical fluids; unable to work properly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a check valve of a hemodialysis machine with a simple and reliable structure. [0004] The technical scheme of the present invention is as follows: a one-way valve for a hemodialysis machine has a first joint and a second joint, the first and second joints are through pipe structures, and the opposite ends of the first and second joints are respectively There a...
