Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with specific embodiments.

[0014] 1. After the product is strictly sterilized before use, the blood to be dialyzed is pumped from the blood inlet 1 of the gravity hemodialysis device into the cylinder of the gravity hemodialysis device, and left to stand for several hours. Under the action of gravity, it gradually penetrates from the left side of the filter membrane to the right side of the filter membrane, and the impurities in the blood are blocked by the filter membrane on the left side of the filter membrane or in the interlayer of the nuclear pore membrane, and what is obtained on the right side is dialysis After the blood is processed, it can be returned to the human body.

[0015] Certainly, the present invention also has other embodiments, and any technical, principle and technical improvements made without departing from the spirit of the present invention fall within the protectio...

Abstract

The invention discloses a gravity type hemodialysis device, which belongs to the field of medical equipment, and comprises: a blood inlet (1), a filter membrane (2), and a blood outlet (3); the blood inlet (1) is arranged in a cylinder The upper end of the body, the filter membrane (2) is set in the cylinder, and the blood outlet (3) is set in the lower end of the cylinder; the cylinder is made of medical polyvinyl chloride material; the filter membrane is vertically installed in the cylinder In the middle of the body, the space inside the cylinder is divided into two; the filter membrane is composed of three layers of nuclear pore membranes; the medium density of the three layers of nuclear pore membranes is 5 microns, 3 microns, 0.2 microns, three The order of arrangement of nuclear pore membranes from left to right is 5 microns, 3 microns, 0.2 microns.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a gravity type hemodialysis device. Background technique [0002] Hemodialysis is one of the renal replacement treatments for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body, and passes through a dialyzer composed of countless hollow fibers. ) inside and outside the hollow fibers, material exchange through diffusion / convection, remove metabolic waste in the body, maintain electrolyte and acid-base balance; remove excess water in the body at the same time, and return the purified blood to the whole process. For hemodialysis. Hemodialysis requires a hemodialysis machine. The traditional hemodialysis machine is divided into two parts: a blood monitoring alarm system and a dialysate supply system. The blood monitoring alarm system includes blood pumps, heparin pumps, arterial and venous pressure monitoring, and air monitoring; T...
