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 EVD pipe (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.
Summary of the invention
The object of the invention is for deficiency of the prior art, a kind of EVD pipe of improvement is provided.
For achieving the above object, the technical scheme that the present invention takes is:
A kind of EVD pipe of improvement, the leading portion of described EVD pipe is provided with pressure transducer, drain areae porosae laterales and scale, described drain areae porosae laterales is provided with developing materials, the stage casing of described drainage tube is provided with aperture, the outside of aperture is enclosed with active rubber cover, the inside of drainage tube is provided with metallic support rod, the end of drainage tube is provided with monitoring port, described monitoring port is connected with pressure transducer by monitoring port connecting line, and described monitoring port connecting line traveling is in the medial wall of drainage tube.
The head end of described EVD pipe is closed, and for circle is blunt nosed, and be provided with an independently side opening, pressure transducer faces side opening.
Described drain areae porosae laterales is evenly distributed with 12 drain side openings.
Described small pitch is from drainage tube head end 12cm.
The invention has the advantages that:
1, the front end of drainage tube is provided with pressure transducer, can go out the intracranial pressure of patient by Real-Time Monitoring.
2, the drain areae porosae laterales of drainage tube leading portion is provided with developing materials, can develop under CT, is convenient to clinical observation areae porosae laterales particular location and judges drainage effect.
3, the inner built-in metal support bar of drainage tube, convenient puncture by drainage tube cortex inserts the ventricles of the brain; Support bar can be extracted out from the aperture in drainage tube stage casing, is wrapped at aperture place after extraction by active rubber cover again, effectively avoids extracting the leakage of drainage tube sidewall and retrograde infection after metallic support rod out.
