Pipe cavity cleaning method, tool and device

Abstract

The invention discloses a pipe cavity cleaning method, tool and device. The method comprises the following steps that firstly, a cleaning plug is arranged at one end of a pipe cavity, and the cleaningplug is in interference fit with the pipe cavity; secondly, the cleaning plug is driven to move along the pipe cavity to the other end of the pipe cavity by adopting high-pressure water flow; and thirdly, the first step and the second step are repeatedly carried out until the pipe cavity is cleaned thoroughly. By means of the pipe cavity cleaning method, tool and device, the cleaning plug is in interference fit with the pipe cavity, it is ensured that the cleaning plug can wipe off blood spots or tissue inside the pipe cavity under the action of the high-pressure water flow, and when medicalinstruments with different pipe diameters and longer pipe cavities are cleaned, the pipe cavity cleaning method, tool and device are excellent in cleaning effect.

Description

technical field [0001] The invention relates to the field of medical instrument cleaning, in particular to a lumen cleaning method, appliance and device. Background technique [0002] In the process of medical operations, a large number of instruments or flexible tubes with a lumen are used, and the coagulated blood or tissue is often bonded to the inner wall of the lumen, but the length and diameter of the instruments or flexible tubes are different, and some are long. Up to 5-6m, but the diameter of the tube is only 3.5-8mm, and the inner wall of the tube cavity is difficult to clean. [0003] In the existing cleaning of the inner wall of the lumen, the staff aligns the outlet of the high-pressure water gun with the opening of the end of the lumen, and uses the high-pressure water gun to directly wash the inner wall of the lumen, but it is difficult to clean the blood spots or tissues on the inner wall of the lumen. In addition, due to The lumen is long, and it is set in ...

[0002] In the medical operation process, a large number of instruments or flexible tubes with a lumen are used, and the coagulated blood or tissue is often bonded to the inner wall of the lumen, but the length and diameter of the instruments or flexible tubes are different, and some are long Up to 5-6m, but the diameter is only 3.5-8mm, the inner wall of the lumen is difficult to clean

[0003] In the existing cleaning of the inner wall of the lumen, the staff aligns the outlet of the high-pressure water gun with the opening of the end of the lumen, and uses the high-pressure water gun to directly wash the inner wall of the lumen, but it is difficult to clean the blood spots or tissues on the inner wall of the lumen. In addition, due to The lumen is long, and it is set in a curved state when cleaning. After the pressure water enters the curved inner wall of the lumen, the pressure decreases, and the inner wall of the lumen is difficult to clean.
