Urethra dosing device for urinary surgery

Abstract

The invention discloses a urethra dosing device for urinary surgery. The urethra dosing device comprises a sleeve, wherein the front end of the sleeve is fixedly communicated with a connecting tube in an airtight mode, the outer surface of the connecting tube is communicated with an injection tube through a thread, the injection tube is connected with the connecting tube in an airtight mode, the front end of the injection tube is communicated with an injection bag in an airtight mode, multiple injection ports are formed in the side wall of the injection bag, a backflow resisting baffle, an inner backflow-resisting valve and an outer backflow-resisting valve are sequentially connected from inside to outside on the portions, in the injection ports, of the side wall of the injection bag, a liquid outlet hole is formed in the backflow resisting baffle, the inner backflow-resisting valve is attached to the backflow resisting baffle and blocks the outer face of the liquid outlet hole, and the outer backflow-resisting valve is attached to the inner backflow-resisting valve and blocks the outer face of the free open side of the inner backflow-resisting valve. The liquid outlet hole is formed in the center of the backflow resisting baffle, the front projection of the inner backflow-resisting valve is larger than a half circle, and the front projection of the outer backflow-resisting valve is smaller than a half circle. The centers of the two side faces of the backflow resisting baffle are both concaved inwards to form a horn shape.

Description

technical field [0001] The invention relates to a medical device, in particular to a urethra drug delivery device for urology. Background technique [0002] Due to various reasons, some patients may develop diseases such as urinary tract infection or urinary system inflammation. When the patient is sick, he needs to be treated with medication in time, but the oral medicine needs to be absorbed by the body before acting on the affected area. The drug cannot reach the affected area directly. Therefore, the treatment effect is relatively slow and poor. In order to obtain fast and good therapeutic effect, when the patient develops diseases such as urinary tract infection or urinary system inflammation, the medicine can also be directly applied to the affected area. However, when the irrigator is used for treatment, the dirt in the urethra can easily enter the irrigator, thereby polluting the medicine, causing the medicine not to fully exert its efficacy and causing waste.
