If she has a needle fixed to her stomach with a dressing, can she wipe over it when doing ghusl?
Question

                I have diabetes and to treat it I use a pump instead of injections. This pump has a small needle that is fixed to the stomach for three days, then I change it. This needle is covered with a dressing that prevents water from reaching the needle and the skin beneath it. Is it sufficient when doing ghusl following my monthly period to wipe over it if my period ends within those three days?.
Praise be to Allah.If it is possible to remove 
    the dressing when doing ghusl and wash the skin beneath it, then put it back 
    without it causing any harm, then this is what must be done and it is not 
    permissible to wipe over it. 
But if harm will be caused 
    by removing the dressing, then there is nothing wrong with wiping over it. 
Ibn Qudaamah (may Allaah 
    have mercy on him said): Ahmad said: When he does wudoo’, if he fears that 
    the water may harm his wound, he may wipe over the dressing. 
Similarly if he has put 
    medicine on his wound, and he is afraid to take it off, he may wipe over it. 
    This was stated by Ahmad. Al-Athram said: I asked Abu ‘Abd-Allaah about a 
    wound on the leg on which medicine is put, and one is afraid that removing 
    the medicine when doing wudoo’ may cause harm. He said: I do not know what 
    will harm him, but if he is afraid for himself or is afraid about that, then 
    he may wipe over it. 
Al-Qaadi said concerning 
    dressings on wounds: If taking it off will not cause harm then he should 
    take it off, but if taking it off will cause harm, then the ruling is the 
    same as that on splints, and he may wipe over it. End quote from 
    al-Mughni (1/172). 
Shaykh Ibn Baaz (may Allaah 
    have mercy on him) was asked: What is the ruling on leading the people in 
    prayer in congregation when one has a wound? 
He replied: If the wound is 
    covered with a splint, he may wipe over it when doing wudoo’ or ghusl in the 
    case of janaabah, and that is valid, and his prayer is valid, whether he is 
    leading the prayer, praying behind an imam or praying alone. If there is no 
    splint on it, he may do tayammum for it after washing the parts of his body 
    that are sound, and that is valid and his prayer is valid, because Allaah 
    says (interpretation of the meaning): “So keep your duty to Allaah and 
    fear Him as much as you can” [al-Taghaabun 64:16]. And the Prophet  
    (peace and blessings of Allaah be upon him) and the Muslims who were wounded 
    on the day of Uhud prayed with their wounds. And Abu Dawood (may Allaah have 
    mercy on him) narrated from Jaabir (may Allaah be pleased with him) that a 
    man was wounded and some of his companions advised him to do ghusl, so he 
    did ghusl and died. The Prophet  (peace and blessings of Allaah be upon 
    him) said: “They killed him, may Allaah kill them. Why didn’t they ask if 
    they did not know? The remedy for not knowing is asking.” Then the Prophet 
     (peace and blessings of Allaah be upon him) said: “It would have been 
    sufficient for him to put a dressing on his wound and wipe over it, and wash 
    the rest of his body.” End quote from Fataawa al-Shaykh Ibn Baaz 
    (10/119). 
We ask Allaah to heal you. 
And Allaah knows best.
