Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an automatic negative pressure auxiliary urination device. Background Art

[0002] Urinary incontinence refers to a state in which the ability to control urination is lost due to damage to the bladder sphincter or neurological dysfunction, causing urine to overflow or flow out of the urethra without voluntary control. Some stroke patients are bedridden for a long time, often holding urine or urinating involuntarily, which can easily cause urinary tract infections. Currently, diapers are usually used to absorb urine during the care of bedridden patients, which can easily cause urine overflow or dripping. After urination, urine contacts the skin, which is unhygienic and needs to be wiped frequently. Some nursing methods use urinals to solve the urination problem of bedridden patients. However, for some patients with urinary incontinence due to stroke, there are obstacles in language and movement, and it is difficult for caregivers to provide care in accordance with the needs of patients.
