EVD, as the key measure that reduces intracranial pressure, is widely used at present, and universal gradually in vast grass-roots unit.For acute Medium or severe type craniocerebral injury, cerebrovascular, in the situation such as complicated intracranial tumor is postoperative, EVD plays an important role.Clinical main employing cerebral-ventricle outer conduction device and waist great Chi external drainage device carry out drainage of cerebrospinal fluid at present.
1, cerebral-ventricle outer conduction device: by puncture side ventricular drainage cerebrospinal fluid, then control drainage flow by adjusting the height of external ventricular drainage bottle.Its weak point is, the drainage flow of cerebrospinal fluid need to be controlled by the height of continuous adjustment external ventricular drainage bottle, easily occurs the not enough or excessively drain of drain.Once and drain is excessive, easily cause crack ventricles of the brain syndrome, serious occurred remote part hematoma.
2, waist great Chi external drainage device: by the subarachnoid space drainage of cerebrospinal fluid at puncture waist great Chi position, then control drainage flow by adjusting the height of external drainage bottle.Its weak point and cerebral-ventricle outer conduction device are similar, can occur the not enough or excessive drain of drain.And the excessive drain at waist great Chi position can also cause the integral body of cerebral tissue to move down and then occur transforminal herniation, can threat to life.
Chinese patent application CN201194992Y discloses a kind of Simple craniocerebral external drainage apparatus, comprise puncture drainage assembly, conduit, liquid-collection bag, puncture drainage assembly comprises drainage catheter, rustless steel guide pin, Rule adapter, Rule adapter is connected with supravasal cone joint, liquid-collection bag is communicated with drainage catheter by conduit, liquid-collection bag bottom is provided with leakage fluid dram cone joint and liquid stopping clamp, liquid-collection bag is provided with metering scale, top is provided with anti-backflow device, can be by the suspension height regulation and control patient intracranial pressure of liquid-collection bag, there will not be liquid return, drainage metering is accurate.But yet there are no report about a kind of external ventricular drainage device that possesses flow control function.
Summary of the invention
The purpose of this utility model is that a kind of external ventricular drainage device that possesses flow control function is provided.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of external ventricular drainage device that possesses flow control function, the described external ventricular drainage device that possesses flow control function is comprised of drainage tube, three-way valve, conduit and liquid-collection bag, described drainage tube is connected with conduit one end by three-way valve, the described conduit other end directly connects liquid-collection bag, in one end that described three-way valve is connected with drainage tube, is provided with automatic flow control valve.
Described automatic flow control valve is for setting the flow of liquid and the autocontrol valve of flow velocity in flow and flow velocity threshold Real-Time Monitoring pipeline, and when flow velocity or flow surpass the threshold value of setting, automatic flow control valve can be closed automatically.
Described automatic flow control valve is infrared control valve, by flow rate of liquid and flow in infrared observation pipeline.
This utility model advantage is:
1, on the basis of current cerebral-ventricle outer conduction device, use modern physics technology, control amount and the speed of EVD, and then avoid occurring the not enough or excessively drain of drain, avoid the crack ventricles of the brain syndrome or the remote part hematoma that cause thus, when reaching therapeutic purposes, improve safety;
2, reduce the consumption of national medical resource, and operation is simple due to it, can large-scale promotion arrive vast basic hospital, allow the more patient of basic unit benefit.
