Device and method for the lavage-type introduction of a fecal transplant or of a therapeutically effective substance into the colon of a patient

Method for flushing of liquid substances or of substances dissolved in a liquid or of a stool transplant suspended in a liquid into the colon of a patient, comprising the following steps:

• a) introducing a patient-sided head part (2) of a device into the anus, so that a segment (3b, 3c) of a balloon body with tapered diameter is placed in the area of the sphincter so as to be disposed in a trans-anal position;
• b) filling the balloon body (3) for the purpose of trans-anal sealing and fixation of the device with an air volume, in which the air volume is approximately 10 to 20% lower than the volume of the balloon body in a freely unfolded, entirely shaped state;
• c) connecting a lavage bag for a preparatory cleaning or lavage of the colon to the patient-sided head part (2);
• d) raising the lavage bag above the level of the patient's anus, with opened closure on a patient side of the lavage bag, so as to introduce a large liquid volume with a flush into the colon of the patient;
• e) turning the lavage bag upside down and lowering the lavage bag below the level of the patient's anus, and then using the lavage bag as a collection bag;
• f) connecting a bag for lavage introduction of a therapeutic substance or of a transplant to the patient-sided head part (2);
• g) raising the bag for the lavage introduction of a therapeutic substance or of the transplant above the level of the patient's anus, with opened closure on a patient side of the bag for introducing the volume of the therapeutic substance or of the transplant as a flush into the colon of the patient.
