Description
Technical field
This utility model relates to a kind of EVD pipe, specifically, is a kind of band intracranial pressure sensor external ventricular drainage device.
Background technology
EVD, as release cerebrospinal fluid, the key measure reducing intracranial pressure, is widely used in neurosurgery at present, and popularizes at vast different medical unit.For hemorrhage or ischemic cerebrovascular, complicated intracranial tumor peri-operation period EVD plays an important role.While current EVD, implantation intracranial pressure sensor parts dynamically observe intracranial pressure becomes trend.And intracranial pressure sensor is generally all integrated in ventricular drainage tube, for the true intracranial pressure in accurate measurements brain deep.
The external ventricular drainage device (as Johnson & Johnson codman etc.) of the band intracranial pressure sensor used clinically now has problems when using.One, drainage tube inserts the particular location that the imaging examinations such as CT after Intraventricular cannot learn head end side opening region, and doctor only by virtue of experience can estimate side opening position, poor to the judgement of drainage effect.They are two years old, be convenient to make drainage tube be inserted into patient's Intraventricular, except intracranial pressure sense line, be also provided with metallic support rod in drainage tube be beneficial to the ventricles of the brain that puncture, after puncture puts in place, metallic support rod is taken out from the seam that drainage tube sidewall is reserved, although silica gel drainage tube latasuture keeps airtight in the ordinary course of things, when drainage tube produces bending, easily there is drainage-fluid and leak outside in sidewall tear place, antibacterial enters ventricular system by leakage place is reverse, forms cerebrospinal fluid retrograde infection.
About can take into account dynamic monitoring intracranial pressure, medical worker's observation directly perceived and control the concrete degree of depth of drainage tube side opening simultaneously, peri-operation period effectively can be avoided again to go out the external ventricular drainage device of skin section ventricular drainage tube leakage simultaneously, have not yet to see report.
