Description

Urinary system device of dosing

Technical Field

The invention relates to a urinary system drug delivery device.

Background

For various reasons, some patients can suffer from diseases such as urinary tract infection or urinary system inflammation, and after the patients suffer from the diseases, the patients need to take the medicines in time for treatment, but the oral medicines need to be absorbed by human bodies and then act on the affected parts, and the medicines cannot directly reach the affected parts, so the treatment effect is relatively slow and poor. In order to achieve quick and good treatment effect, when patients suffer from diseases such as urinary tract infection or urinary system inflammation, the patients can also directly take medicines, and the currently adopted method is to directly spray liquid medicines to the patients by using a common flusher.

However, the above steps have the following disadvantages in operation:

1) because the point of flushing is single, the effect of single flushing is poor, and the obvious treatment effect can be generated by flushing more than 3 times repeatedly;

2) when in flushing, the waste liquid flowing out of the vaginal orifice can be scattered on the ground and hands, which brings great inconvenience;

3) the liquid medicine flushed into the body cannot be remained, so that the drug effect is poor.

Therefore, the urinary system drug delivery device capable of realizing comprehensive flushing, effectively treating waste liquid and realizing retention and soaking is designed.
