Description

TECHNICAL FIELD The present application relates to a care product, particularly a urine collecting device.

Urinary incontinence in elderly people, disabled people, and post-operative patients' urine collection generally employs the simplest urine collection bag, utilizes the difference in liquid level via a urinary catheter, and collects urine by gravity. The collection in the bag is realized. The drawback is that unless the tube path is placed from high to low, it cannot be used properly and urine leaks out without flowing into the urine collection bag and soils the bedding. China has an enormous number of elderly people, but most of them do not have disability or incontinence, and can only walk. Symptoms such as frequent urination, urgency, and incontinence of the urine appear due to deterioration of physical function, and especially during nighttime rest, the patient often wakes up to go to the toilet, falls and is injured, and sleep quality is poor. There is a risk of accidents and additional labor, such as needing helpers.
