Embodiment 1

[0011] Example 1, producing a rust remover containing 6% of sodium bisulfite and 4% of sodium dithionite: take 6 grams of sodium bisulfite, 4 grams of sodium dithionite, and 990 grams of distilled water. Add the obtained sodium bisulfite and sodium dithionite into distilled water, dissolve and mix to prepare 1000 grams of hemodialysis machine fluid circuit rust remover.

Embodiment 2

[0012] Example 2, producing a rust remover containing 8% sodium bisulfite and 5% sodium dithionite: take 8 grams of sodium bisulfite, 5 grams of sodium dithionite, and 987 grams of distilled water. Add the obtained sodium bisulfite and sodium dithionite into distilled water, dissolve and mix to prepare 1000 grams of hemodialysis machine fluid system rust remover.

Embodiment 3

[0013] Example 3, producing a rust remover containing 10% sodium bisulfite and 6% sodium dithionite: take 10 grams of sodium bisulfite, 6 grams of sodium dithionite, and 984 grams of distilled water. Add the obtained sodium bisulfite and sodium dithionite into distilled water, dissolve and mix to prepare 1000 grams of hemodialysis machine fluid system rust remover.

Abstract

The invention discloses a rust remover for a liquid passage system of a haemodialysis machine. The rust remover is characterized by comprising the following components in percentage by weight: 6 to 10 percent of sodium hydrogen sulfite, 4 to 6 percent of sodium hydrosulfite (rongalite) and 84 to 90 percent of distilled water. The rust remover solves the problem that rust deposited on the inner wall of the liquid passage system of the haemodialysis machine affects the integral performance of the haemodialysis machine, and is adaptive to clearing use of the inner wall of the liquid passage of the haemodialysis machine.

Description

technical field [0001] The invention relates to the field of use and maintenance of medical instruments, in particular to a derusting agent for cleaning and derusting the liquid circuit system of a hemodialysis machine. Background technique [0002] At present, in the hemodialysis machines used in the medical and health industry, brown rust is often deposited on the inner wall of the fluid circuit, which seriously affects the performance and use of the dialysis machine. Contents of the invention [0003] In order to solve the problem that rust is deposited on the inner wall of the fluid path system of the hemodialysis machine after a period of use, which affects the performance of the dialysis machine, the invention invents a special rust remover for the fluid path of the hemodialysis machine with the function of cleaning and derusting. [0004] In order to solve the above-mentioned technical problems, the present invention adopts a technical scheme that is a rust remover ...
