Abstract

The invention provides a negative-pressure colostomy bag, which comprises an external bag, a mounting ring, and an internal bag, the interior of the external bag is provided with a containing space, the containing space runs through the external bag, so that a first opening and a second opening are formed in the external bag, the mounting ring is connected to the first opening of the external bag,a negative pressure generator is connected to the second opening of the external bag, and the negative pressure generator is located outside the external bag; the internal bag is contained in the containing space, the interior of the internal bag is provided with a collecting space, one end of which is open, the opening of the internal bag is fixedly connected to the mounting ring, and the opening of the internal bag is communicated with a circular opening of the mounting ring; a negative pressure space is formed between the external bag and the internal bag, and the negative pressure generator can be adjusted to enable the negative pressure space to be under a negative pressure state; both the external bag and the internal bag are made of an elastic stretchable material, and the externalbag is provided with a plurality of surrounding wavy folds, so that the external bag can be folded to be compressed or unfolded. The invention can ensure that the opening of the colostomy bag can beattached with skin.

Description

【Technical field】 [0001] The invention relates to the field of medical technology, in particular to a negative pressure colostomy bag. 【Background technique】 [0002] Medically, for patients who cannot excrete normally, a stoma that can be opened and closed is opened on the abdominal wall of the patient, and the excrement is collected by inserting an ostomy bag on the stoma. Normally, the stoma is closed. When it is necessary to discharge the excrement in the body, the stoma opening is opened, and the excrement is discharged into the ostomy bag for collection. The single-port ostomy bag in the prior art only has two parts, the mouth and the pouch, and the mouth of the bag is fixed to the skin at the stoma by glue, but when sweating or used for a long time, the glue is easy to be separated from the skin of the stoma. The detachment of the skin causes the ostomy bag to fall off, and the shedding of the ostomy bag will cause the collected excrement to overflow from the mouth ...
