Abstract
The utility model discloses a ventricle external drainage device, comprising a bottle and a drainage tube. One end of the drainage tube is connected with the liquid inlet port of the bottle; the drainage tube is provided with an observation pot for the drip speed, the drainage tube is provided with a hole, and the hole is provided with an anti-siphon device. The ventricle external drainage device is used for the intracranial hypertension emergency salvage and the external drainage of the cerebrospinal fluid. The ventricle external drainage device can also be used for the trauma, the inflammation, the external drainage of the postoperative tumor, lower drainages of parts of the dura.
Description
Technical field
This utility model relates to medical negative pressure drainage technology, relates in particular to a kind of EVD device.
Background technology
In the neurosurgery, often need carry out the EVD operation,, reach the effect that reduces intracranial pressure or reduce courageous and upright cerebrospinal fluid stimulation, arachnoid adhesion to discharge hematocele, hydrops.But, the present outdoor drain corollary apparatus of domestic anencephaly still, often use transfusion device, urinal or other drainage bags (bottle) to piece together temporarily, not only connect difficulty, waste time and energy, and influence the degree of sterile working, and maximum problem is because of not resisting siphon to cause drain excessively to cause intracranial low pressure.
Summary of the invention
Main purpose of the present utility model is the shortcoming at prior art, and a kind of EVD device is provided, and has solved the over-drastic problem of drainage of cerebrospinal fluid.
The technical solution of the utility model is: a kind of EVD device, comprise bottle, drainage tube, one end of described drainage tube is connected with the inlet of described bottle, also is provided with the speed of dripping that has aperture on the described drainage tube and observes kettle, and described aperture is provided with anti-siphon means.
Described anti-siphon means is made up of the air hose of funnel type and the filter membrane that is encapsulated in this air hose top, assigns on the aperture of Hu Bi of described speed observation kettle.
The tube wall of described drainage tube is marked with scale.
Described bottle is marked with scale.
Described speed is observed to be with on the thin diameter tube above or below the kettle and is dripped a fast control valve.
The bottom of described bottle is provided with liquid outlet, and this liquid outlet is equipped with stopper.
This utility model is provided with anti-siphon means, can avoid drainage of cerebrospinal fluid excessive; Be provided with and drip speed observation kettle, can control cerebrospinal fluid and drip speed, and can judge intracranial pressure according to dripping speed; Drainage tube is marked with scale, is convenient to the nurse and adjusts height; The bottom of bottle is provided with liquid outlet, desirable cerebrospinal fluid laboratory examination.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, drainage system of the present utility model by graded tube 1, drip speed and observe kettle 2, drainage tube 3 and indicate the measuring bottle 4 that graduated bottom is provided with stopper 7 and be connected in sequence, on a speed observation kettle 2, have aperture, and assigned anti-siphon 5, be with on the thin diameter tube below a speed is observed kettle 2 and drip a fast control valve 6.The each several part of drainage system of the present utility model is made by softish transparent or semitransparent material, and supporting be an integral body, connect easy to use, aseptic degree height.
During use, the light measuring bottle 4 of pressing forms negative pressure with the portion gas of discharging in the bottle, the intracranial of then end of graded tube 1 being inserted the patient also wraps up, because the pressure of intracranial is big, so cerebrospinal fluid is just observed kettle 2, drainage tube 3 inflow measuring bottles 4 along graded tube 1, a speed.In the drain process, can will drip the roller scroll-up/down of fast control valve 6, dripping of control cerebrospinal fluid is fast, and simultaneously according to dripping speed judgement intracranial pressure.Owing to the anti-siphonage of anti-siphon 5, can not cause the hypotony of intracranial owing to drain, guaranteed patient's safety.When the cerebrospinal fluid in needs take out measuring bottle 4 was done laboratory examination, corkage 7 flowed out cerebrospinal fluid to test glass or chemical examination bottle.
This utility model is applicable to intracranial hypertension emergency rescue, external ventricle drainage; The wound relevant, inflammation, tumor post-operation external drainage with the ventricles of the brain; Drain etc. under the part dura mater.
Though this utility model discloses as above with a preferred embodiment, be not in order to limit the scope that this utility model is implemented.Any those of ordinary skill in the art, in not breaking away from invention scope of the present utility model, when doing a little improvement, promptly every equal improvement of doing according to this utility model should be invention scope of the present utility model and contains.
