A new type of urethral drug delivery device for urology

Abstract

The invention discloses a novel urethra dosing device for urinary surgery, and belongs to the field of urological disease treatment instruments. The novel urethra dosing device comprises a syringe, and a cleaning liquid pushing and injecting cavity, a cleaning dirt suction cavity and a dosing cavity which are separated from one another are arranged in the syringe; the cleaning liquid pushing and injecting cavity and the cleaning dirt suction cavity surround the dosing cavity, and a dosing chamber communicated with the dosing cavity is formed among the cleaning liquid pushing and injecting cavity, the cleaning dirt suction cavity and the syringe; the outer surface of the syringe is in wavy shape, wherein protruding parts and concave parts on the outer surface of the syringe are connected alternately, the front end face of each protruding part is provided with a cleaning liquid spraying pipe, the outer end of each protruding part is provided with a medicine spraying opening, and each concave part is provided with a suction pipe; a first piston, a second piston and a third piston are arranged in the cleaning liquid pushing and injecting cavity, the cleaning dirt suction cavity and thedosing cavity respectively. According to the dosing device, a cleaning mechanism and a power source mechanism of a sewage discharge mechanism are integrated, the dosing device is convenient to control, operation is simplified, secondary infection caused by pollutants to the urethra can be prevented, and a clean application environment is provided for liquid medicine; complete output of the liquidmedicine is achieved, dosing is uniform, and drug effects of the liquid medicine can be given play of.

Description

technical field [0001] The invention relates to the field of urological disease treatment instruments, in particular to a novel urethral drug delivery device for urological surgery. Background technique [0002] Due to various reasons, some patients may suffer from urinary tract infection or inflammation of the urinary system. When the patient is sick, he needs to be treated with medication in time. However, 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 therapeutic effect is relatively slow and poor. In order to obtain fast and good therapeutic effect, the medicine can be directly applied to the patient's diseased part. The current method is to use an ordinary irrigator to directly spray liquid medicine on the affected area. Although it is more convenient to use, when using this irrigator, the dirt in the urethra can easily enter the irrigator, thereby contaminating the...

AI Technical Summary

Problems solved by technology

But it has the following disadvantages: one, the dirt-absorbing body is not connected to the power source mechanism, and the adsorption process of the dirt in the urethra is not clear; Spray medicine, but as the piston is pushed forward, the conduit connected to the medicine ball in the area where the piston passes through is no longer connected to the medicine liquid, and the medicine cannot be sprayed continuously, and the medicine medicine ball at the front end of the piston is always spraying medicine, so the medicine is not uniform enough
