Description
Technical field
The utility model belongs to technical field of medical equipment, is related to a kind of medical catheter access times control device and is
System.
Background technique
Medical catheter mainly by medical material (such as medical plastic PVC, nylon, polyurethane and silicon rubber etc.) prepare and
At in pluggable human body or in vitro for a kind of tubule of disease treatment or diagnosis.According to whether power supply is divided into nothing
Source and active catheter, such as perfusion tube, surgical drainage conduit etc. belong to passive conduit, and as being detected for gastroesophageal reflux disease
Etc diagnostic catheter belong to active catheter more.For the conduit of active class, function is different depending on the application, is integrated with spy on conduit
Fixed sensor (types such as physics, chemistry, biology), cable (signal transmission, power supply etc.), data-interface (connect with host equipment
Connect) etc. components.
The cavity that medical catheter generally passes through human body enters human body, all might have and contacts with human body fluid, blood, for
The conduit for monitoring class is usually longer in inside of human body residence time, is easy to cause germ to be adsorbed on conduit with body fluid Long Term Contact
On, it is used if disinfection is insufficient to other patient, it is easy to cause cross-infection.For the sensing integrated on conduit
Device, with using the time to increase, performance is likely occurred decline, such as chemical sensor, as the chemistry in use process is anti-
It answers, the ingredient of sensor internal constantly changes, and after long-term use, sensor performance may will be not enough to support again
