Kidney dialysis, inhalers, blood donation, and the use of toothpaste, among other things, during Ramadan. Perhaps you have a guiding word for us?

Question:
May Allah reward you with good and do you well. Many matters have become new to the people, Shaykh Salih: dialysis for the patient with kidney failure, this inhaler, and the like; the one who donates blood or wants to have a blood test; the use of toothpaste; and the extraction of teeth. All these matters are asked about by people. Perhaps you have a guiding word regarding all of them. May Allah reward you with good.

Answer:
As for kidney dialysis, there is no doubt that it breaks the fast of the one fasting, because it involves introducing substances and non-nutritive fluids into the body, and medical fluids enter the body while substances are removed from it. So kidney dialysis breaks the fast of the one fasting. If the one fasting needs it, he is considered to have broken his fast due to his illness, and he makes up the days on which he underwent dialysis during the daytime of Ramadan by fasting other days, and praise be to Allah. He is excused for the dialysis during Ramadan because of his need and necessity for it, but he must make up this day.
As for the issue of blood, introducing blood into the fasting patient and resuscitating him with blood, this breaks his fast, because it is equivalent to eating and drinking, since blood is nourishing, nourishing the body, and it is equivalent to eating and drinking. So if he is resuscitated with blood, he thereby invalidates his fast, and he must make it up. He is excused because of the illness that compelled him to do so. As for drawing blood from the patient, from the one fasting, as for drawing blood from the one fasting, if it is a large amount, it invalidates the fast, because it is like cupping, and it is established in the authentic hadith that cupping breaks the fast of the one fasting, and it is the drawing of blood. So if a large amount of blood is drawn from the one fasting for donation or to resuscitate a patient, he thereby invalidates his fast, but he is excused and there is no sin on him because he did this out of necessity. However, he must make up the fast, because this is to save a protected life from destruction, so it is permissible for him to do so, but he makes up this day. As for drawing a small amount of blood for analysis, like a drop or two drops, this does not harm, if Allah wills.
As for the extraction of a tooth, if a person is suffering from a tooth, he extracts it while fasting and there is no blame on him. The blood that comes out during the extraction, he spits it out, he spits it out and does not leave anything of it to go into his stomach while he is able and in control. If something goes in and seeps in without his choice, there is no blame on him for that. So he may extract his tooth while fasting, meaning out of necessity, and because the mouth is considered external. As for toothpaste, there is nothing wrong with its use by the one fasting, but on the condition that nothing of it goes down his throat; rather, he spits it out and gets rid of it. Yes.
