The serial numbers of the affected devices are located on the back of the device.  See photo under Additional Links below.

Recalling Firm:
Phillips Respironics, Inc.
1001 Murry Ridge Lane
Murrysville, Pennsylvania 15668-8517
Reason for Recall: There is a potentially defective component on the Trilogy Ventilator power management board which could affect the function of the device. If this issue is not corrected it is possible that the ventilator may fail to deliver mechanical breaths and that the alarm functionality may be reduced to indicate ventilatory failure, resulting in serious adverse health consequences or death.
During production testing Philips Respironics discovered that the affected Trilogy ventilators contain a potentially defective ferrite component on the power management board of the device.
Public Contact: Customers who have questions about this recall, require further information or support concerning this issue, may contact their local Philips Respironics representative through the Customer Care Center, 1-800-345-6443, available 24/7.
FDA District: Philadelphia District Office
FDA Comments:  
On February 11, 2014 the firm initiated the recall by phoning their direct customers who are primarily wholesale dealers of home healthcare products. The firm followed up their phone calls by sending recall notification letters to their customers. On February 19, 2014, the firm issued a press release to notify consumers about the recall. 
Philips Respironics is instructing customers to remove the affected devices from service and to return them to Philips for replacement. All distributors, providers, and customers with potentially affected Trilogy devices will have their units replaced.
Class I recalls are the most serious type of recall and involve situations in which there is a reasonable probability that use of these products will cause serious adverse health consequences or death.
Health care professionals and consumers may report adverse reactions or quality problems they experienced using these products to MedWatch: The FDA Safety Information and Adverse Event Reporting Program either online, by regular mail or by FAX.

ValleyLAB Force2 電燒機燈號顯示異常

(http://bme.freebbs.tw 醫學工程論壇同步發表)

名稱: ValleyLAB Force2 電燒機

故障情形:燈號顯示異常
故障原因:U8(4018) U29(ICM7018) IC故障

這台算老機器了,報修說燈號轉換有問題;單雙極切換,燈不會亮,七節顯示器最後一碼也不亮;加上standby時燈該熄時,反倒特亮....
不過能量輸出是OK,同事就直覺應該是顯示邏輯IC上的問題,問了代理商,己經停產囉,要換板子也沒得換了,同事想,應該還可以檢修,那就拿電路圖來,對照檢修吧。
查下來,結果U8 4018邏輯IC掛了,換了後stnadby燈號正常了,繼續下來,查到U29(ICM7018),各腳好像都OK,只好請出示波器了,其中一腳沒輸出,這附近沒得買,想到之前報廢的Force2,不知道拆了丟了沒,趕快去挖出來。
還好,沒丟,這個U29是LED顯示段的驅動IC,應該是有機會故障,所以原廠有設腳座,那就省事多了,找到舊機上的U29,換了,OK。


同事Q電路的功力及不棄的精神,佩服;廢機放那麼久,總算有效力的時刻...感動。呵....
