Description
Technical field
The present invention relates to a kind of drainage line with pressure transducer, it is mainly used in urethral catheterization drainage process measuring bladder
Interior pressure, supporting with special uroflow monitor, realize " bionical urinate ", it is a kind of disposable medical disposable material, belong to
In technical field of medical instruments.
Background technology
Indwelling urinary catheterization is the conventional care method that catheter is retained in intravesical drainage of urine, because it has operation
Simplicity, good biocompatibility, can effectively drainage of urine, deep the advantages of keep xerosis vulae recognized by medical personnel and patient
Can.After long-time indwelling catheter, the bladder of patient is hollow for a long time, and bladder function is in useless state, easily causes de- pipe
Dysuria or even urine retention afterwards.Bladder preservation function therefore in cathing process, by measuring intravesical pressure, according to patient
Intravesical amount of urine increases, intravesical pressure reaches and controls drainage line to open during normal voiding pressure, keeps one one, bladder
Relax, carrying out " bionical urinate " is following research direction of this subject.
Zl201210593072.2 and zl201310463705.2 of the present inventor etc. all proposes by measuring intravesical
Pressure carries out " bionical urinate " technical scheme, and the common feature of above technical scheme is by arranging one in drainage line
" reservoir cavity " or " pressure perception window ", in " reservoir cavity " or " pressure perception window " periphery, monitoring intravesical pressure becomes
Change, control drainage line to open, reach the purpose of " bionical urinate ".But due to being subject to " reservoir cavity " or " pressure perception window " bullet
Property material tension concordance, to shape the impact such as elastic process consistency, ambient temperature larger, find in implementation process,
When monitoring intravesical pressure by " reservoir cavity " or " pressure perception window " periphery, the pressure value that it monitors is true with intravesical
Between real pressure, deviation is very big, and pressure monitoring precision is difficult to bladder pressure in actual response human body and changes it is impossible to meet " bionical row
The technical requirements of urine ".
Because the liquid in pipeline liquid injecting device has good pressure transmission effect, monitoring when urine fills in drainage line
Pipeline inner pressure just can directly perceive intravesical pressure, and pressure data is stably difficult disturbed.For this reason, the present inventor proposes one kind
Drainage line technical scheme with pressure transducer, as one kind of the zl201310463705.2 technical scheme of the present inventor
Substantial improvements and supplement, meet the clinical needs of " bionical urinate " further.

It is cut off urine drainage and there is the elastic pipeline of reproducibility.Typically, feed tube is in upper connection catheter and bladder, row
Liquid pipe, in the next connection urinal, is combined into complete Urinary catheter road.Pressure monitoring chamber is arranged at the taper of drainage line
Any one position between joint and urine drainage bag.
Described feed tube, discharging tube adopt medical macromolecular materials molding, typically can adopt flexible PVC, silicon
Glue, latex or polyurethane material.
The invention has the advantage that during indwelling catheter, by pressure transducer is connected work with pressure monitoring chamber,
Accurate pressure change in dynamic measurement drainage line, the true pressure in perception human bladder, realize facing of " bionical urinate "
Bed function.Monitoring method is subject to material physical property, moulding process level, ambient temperature effect few, and monitoring pressure precision is high, unanimously
Property is good.
