Description

Technical Field

[0001] The utility model relates to the technical field of feces drainage, in particular to a feces drainage catheter. Background Art

[0002] Fecal drainage bag is a medical device used clinically to drain feces for patients with fecal incontinence. Fecal incontinence is common in critically ill patients, comatose patients, and patients who have lost consciousness. Because the anal sphincter of patients with fecal incontinence is relaxed, they cannot control their stool. If they do not drain, the perianal skin may be soaked, and redness, swelling, erosion, or even ulcers, eczema, and other inflammations may occur. The drainage bag drains the fluid or semi-fluid feces in the patient's body into the fecal collection bag through a drainage tube partially built into the anus, thereby reducing the workload of clinical nursing.

[0003] The fecal drainage device requires manual delivery of the balloon to the human anus, and then the balloon connector is filled with saline or sterile water through the first flow channel of the tube body to fill the balloon and form a seal. However, after the balloon is delivered into the human body, on the one hand, the inflation or deflation status cannot be observed, on the other hand, if the inflation is not in place, the balloon seal will be affected during use, and on the other hand, if the balloon is not deflated in place after use, it is easy to cause secondary damage to the human body when it is taken out.
