Description
Technical field
The utility model is related to technical field of medical instruments, is a kind of EVD and hematoma clearance dress specifically
Put.
Background technology
EVD art be through cranial drill permeability ventricular puncture after, the drainage tube front end that will have several side openings is placed in the ventricles of the brain
Interior, cerebrospinal fluid is drawn a technology outside brain by the external aseptic drainage bottle in end.EVD art be rescue intracranial hypertension,
The important method of the serious conditions such as brain trauma, encephaledema, cerebral hemorrhage, internal hydrocephaly, can effectively drain ICV
Blood and blood contained cerebrospinal fluid, reduce intracranial pressure, mitigate encephaledema, it is to avoid or the breaking-out of reduction cerebral angiospasm, reduce brain function
Damage, improved patient clinical illness.Ventricular hemorrhage onset is anxious, the state of an illness is dangerous, and such as treatment can cause seriously not in time
It is disabled or even dead, if telocoele is filled to form ventricles of the brain casting mold by a large amount of hemotoncus, easily there is internal hydrocephaly, cause brain
Hernia, the hemotoncus of ventricles of the brain casting mold can oppress thalamus, brain stem, cause patient's stupor, respiratory arrest；Red blood cell in hemotoncus is dissolved
Afterwards, the vasoactive factors such as substantial amounts of free radical, histamine are can release, causes vasopasm, cause secondary lesion；Hemotoncus generation
The acid product for thanking to generation can influence nerve cell function.Hemotoncus in the timely and effective removal ventricles of the brain especially contacts ventricles of the brain casting mold
It is the key for treating this disease.Current EVD adds the therapy of urokinase perfusion to have certain treatment for ventricular hemorrhage
Effect, but elimination efficiency is low, and the circulation loop held cannot be formed.The elderly should not implement general anesthesia due to weak, open cranium hand
Art etc..The minimally invasive drainage of removing of intracranial hematoma is to be used to treat a large amount of cerebral hemorrhage most common methods in recent years.Due to blood stream
Can be solidified quickly after going out blood vessel, adding very fast hemotoncus of removing has the possibility for causing bleeding again, so often can not during Minimally Invasive Surgery
Can disposable fully erased hemotoncus, it is necessary to indwelling drainage tube CD, and need to inject Urokinase clot lysis blood clot repeatedly, instead
Multiple saline injection is rinsed.Original drainage tube is rinsed drainage, and the dressing and conduit of wrapping are switched on every time
Interface, it is necessary to wear gloves, sterilize repeatedly, the dressing of this wrapping of not only wasting time and energy, waste, and open operation also has and draw
The possibility of infection is played, the development of this Minimally Invasive Surgery is have impact on.
Chinese patent 200820125717.9, discloses a kind of closed intracranial hematoma drainage flusher, including encephalic is worn
Thorn drainage tube, irrigation drainage tube；The entrance point of irrigation drainage tube is provided with joint, and the port of export of irrigation drainage tube connects drainage bag,
On irrigation drainage tube ball, rear clip and drop kettle are inhaled from joint to front clip, plastics are sequentially provided between drainage bag；Joint and encephalic
The outlet connection of puncture drainage tube；Three-limb tube is added between joint and front clip, it leads directly to and is partially in normal open shape
State, the bypass interface of three-limb tube is equipped with sealed gum cap, by bypass interface closure.The flusher can make taking out for intracranial lesion
Attracting stream and the medicine such as intracavitary administration urokinase can all complete in the case of completely closed.Chinese patent
201020672204.7, disclose a kind of external ventricular drainage device, including drainage tube, coupling assembly and drainage metering component, institute
State drainage metering component to stop and drainage bag including upper drainage tube, flow regulator, drainage bottle, lower drainage tube, water, upper drainage tube one
End is connected to drainage bottle, and drainage bottle lower end is connected by lower drainage tube with drainage bag, and upper drainage tube is provided with flow regulator,
Stop equipped with water on lower drainage tube.During cerebrospinal fluid or hemotoncus liquid can be drawn and causes drainage bag by drainage bottle by the device, solution is realized
Except cerebrospinal fluid (cephalophyma) dyshaemia, the purpose of cranium pressure is reduced.Above-mentioned patented technology can realize the function of EVD,
But have as a drawback that：(1) during row drainage, can only merely reduce intracranial pressure, drain part cerebrospinal fluid, it is impossible to from real meaning
Hemotoncus, virulence factor etc. are removed in justice；(2) during drainage, drainage tube must be adjusted according to the height of intracranial pressure highly
So as to control drainage flow and drainage speed, drainage speed is too fast or drainage flow may excessively cause intracranial pressure reduction too fast and occur
Low intracranial pressure induces hernia cerebri, and drainage speed is excessively slow or drainage flow or may not reach therapeutic purposes at least；(3) drainage tube is inserted
Afterwards, can only unidirectionally outwards a small amount of drainage, it is impossible to injecting the controls such as the medicines such as fibrinolysin dissolving hemotoncus or Effct of Thrombin Injected in the ventricles of the brain
System bleeding again.In view of the shortcomings of the prior art, it is necessary to research and develop a kind of EVD and hematoma clearance device, realize cerebrospinal fluid
Lasting, circulation, a large amount of drainages and removing hemotoncus, and on this kind of device, yet there are no report.
