Description

Intelligent bladder irrigation control system

technical field

The utility model relates to a medical device for flushing the bladder, in particular to an intelligent bladder flushing control system for precisely controlling the inflow and discharge of bladder flushing liquid.

Background technique

With the widespread application of three-lumen catheters, more and more closed bladder irrigation methods have been applied clinically. Compared with flushing the bladder with a irrigator, the closed flushing method has the advantages of reducing the chance of bacterial invasion, a large amount of continuous flushing and effectively reducing the workload of nursing, but the closed flushing method also has the disadvantage that the bladder cannot be properly cleaned during the flushing process. The filling defect of the urine tube is due to the open state of both the infusion channel and the outlet channel. After entering the bladder, the flushing fluid only swirls around the front end of the urinary catheter before being drawn out. This will leave a "hygienic dead angle" and cannot be achieved. Optimal rinse effect.

In order to solve the defects of the closed irrigation method, human control is often used in clinical operations, that is, when the irrigation solution is poured into the bladder, the nurse or operator will manually clamp the outlet channel of the irrigation solution to fill the bladder. After the amount of liquid is taken, the nurse or operator closes the input channel and opens the outlet channel. After the flushing fluid in the bladder is drawn out, the outlet channel is clamped and the input channel is opened, and so on until all the flushing fluid in the bladder is used up. until.

At present, there is no controller on the market that can be used to alternately open and close the two channels during bladder flushing.
