MAQUET MODUEVO(ENERGY)

[145754916] (b)(4). Maquet (b)(4) conducted following initial investigation after receiving the complaint. Dhr of this concerned ceiling supply unit(csu) was reviewed. This unit was produced in jun of 2018, the dhr showed no any deviation identified from the manufacturing process and final release testing. Complaint historic data was also reviewed for any similar case reported in the past. Around (b)(4) units moduevo energy have been delivered since year 2016. Till now no similar complaint were received. When adjust the height of energy by handle, the screw rod moves upward or downward. When we put the hose on the brass nut, we found that the hose would not fall off during the movement, when the brass nut and the bearing housing bite, the hose gets stuck inside. So according this, it is concluded the hose was pulled into the screw rod when energy moves, and the hole in the o? Hose was crushed when the brass nut bit the bearing housing. Maquet field service engineer cut the part with hole of the o2 hose, then re-connect the hose with a connector. Furthermore, the hoses were tied together with cable ties to make sure they will not be pulled into the screw rod when energy moves, to prevent the further damage. Maquet (b)(4) is collecting more detail information for further investigation, and the result will be provided in follow-up/final report.
