Description

Technical Field

[0001] This utility model relates to the field of blood perfusion device technology, and in particular to a blood perfusion device outer surface cleaning device. Background Technology

[0002] Blood perfusion devices are Class III sterile products and must pass sterilization before they can be shipped and sold. Currently, the main sterilization methods for perfusion devices are high-temperature moist heat sterilization and radiation sterilization. Radiation sterilization is greatly affected by scale and geographical limitations, and most manufacturers cannot use it, so they can only use high-temperature moist heat sterilization. High-temperature moist heat sterilization inevitably causes water stains and other substances that affect the appearance of the blood perfusion device to appear on its surface. Blood perfusion devices must be cleaned on the surface before labeling and packaging.

[0003] Since blood perfusion devices are all cylindrical in shape with end caps and caps on both sides, and the end caps all have protruding vertical ridges, surface cleaning can only be done manually. However, manual wiping is inefficient, produces mediocre cleaning results, and wastes manpower. Therefore, how to improve the cleaning speed and effectiveness of blood perfusion devices while reducing labor costs is an important issue that needs to be addressed in the design of external surface cleaning devices for blood perfusion devices. Summary of the Invention

The rotating gear 1003 drives the adjacent rotating gear 1003 to rotate, so that the two rotating gears 1003 on the same side rotate simultaneously. The rotation of the rotating gear 1003 drives the support block 1011 to rotate. The support block 1011 drives the fixed main body 12 of the hemoperfusion device to rotate. During the rotation, the sponge block 902 wipes and cleans the surface of the main body 12 of the hemoperfusion device. Cleaning solution and clean water are respectively injected into the two water tanks 701 on the top of the cleaning shell 1. When cleaning the blood perfusion device body 12, the cleaning solution is first drawn by the pump 703. The cleaning solution enters the sponge block 902 through the infusion tube 1 704, infusion hose 705, infusion tube 2 706, flow tube 904, flow box 901 and flow tank 903. The sponge block 902 absorbs the cleaning solution and cleans and wipes the surface of the blood perfusion device body 12.
