There is piston 21, the inner space of liquid storage bottle 2 is divided into I space, the two spaces of II space by piston 21, and piston 21 can be described
Motion is produced in the presence of the pressure difference of two spaces.The distal end of drainage tube 3 is inserted into operative site, and by brain ridge therein
Liquid is drained in I space of liquid storage bottle 2;And the air inlet of peristaltic pump 1 is communicated with II space of liquid storage bottle 2.In drainage of cerebrospinal fluid
In operation, releasing cerebrospinal fluid speed will slowly, and the present invention is controlled by following principles to drainage of cerebrospinal fluid speed:
When brain room pressure is larger, drainage tube 3 is pierced into after the ventricles of the brain, and cerebrospinal fluid can automatically flow into I space of liquid storage bottle 2
Interior, piston is moved downward, and the rate of air sucked in required in certain time can be limited due to peristaltic pump, controls II space size rate of change,
And then the extraction amount of certain time cerebrospinal fluid is controlled, prevent that brain indoor pressure-reducing is too fast;When ventricles of the brain pressure is smaller, peristaltic pump pumps
Air in II space, piston 21 is moved downward in the presence of pressure difference, and then extracts cerebrospinal fluid, also due to peristaltic pump being capable of essence
Really control also control the speed of brain indoor pressure-reducing well under the rate of air sucked in required in the unit interval, the operating mode.

It is easy, and ensure that cerebrospinal fluid will not directly pollute peristaltic pump pipe 11, but inevitably to the peristaltic pump
Pipe 11 causes air pollution.Further, since the gas outlet of peristaltic pump 1 is connection air, to prevent outside air pollution brain
Spinal fluid drainage system, air cleaner 5 is also provided with the gas outlet.
In embodiment, occur to avoid peristaltic pump 1 from operating the too fast situation for causing brain room pressure to reduce rapidly, even
Connect peristaltic pump 1 allows fluid from cerebrospinal fluid with being also provided with one-way overflow valve 4, the one-way overflow valve 4 on the pipe of liquid storage bottle 2
Drainage system external-to-internal one-way flow.Likewise, because one end of one-way overflow valve 4 is communicated with extraneous air, also even
One end of air is connect there is provided air cleaner 5.The operating pressure of one-way overflow valve 4 can be adjusted, for convenience of reading, unidirectional
Overflow valve 4 is marked with operating pressure scale.During use, if peristaltic pump 1 rotates too fast, or cerebrospinal fluid extraction in the ventricles of the brain
After finishing, two spaces pressure difference is more than the operating pressure of one-way overflow valve 4 in hydrops bottle, then valve is opened, and peristaltic pump 1 is directly taken out
The extraneous air after filtering is taken, prevents from further reducing ICV pressure.Preferably, it can also be set on one-way overflow valve 4
Alarm device, sends alarm when the valve is open, reminds doctor to turn down the rotating speed of peristaltic pump 1 or prepare to terminate drainage of cerebrospinal fluid hand
Art.
Generally, it is estimated that by certain medical procedure in the cerebrospinal fluid amount for needing to extract, surgical procedure not
Break and measure the cerebrospinal fluid amount of extraction to estimate operation progress.Peristaltic pump 1 itself has function of measuring, can preset extraction amount and prevent
Only perform the operation excessive.The situation that one-way overflow valve may be opened is considered in embodiment, takes the directly metering of peristaltic pump 1 less accurate
Really, therefore in hydrops bottle volume scale is marked with, facilitates doctor to read cerebrospinal fluid extraction amount, judge operating time.To prevent meaning
Outer situation causes operation to be interrupted, and cerebrospinal fluid is back in the ventricles of the brain, can also be set in the connecting tube of drainage tube 3 and liquid storage bottle 1
Check valve.
Preferably, can be first full of clean liquid in II space of above-mentioned hydrops bottle 2, peristaltic pump 1 is clean by extracting
Liquid operates to complete drainage of cerebrospinal fluid, and the program make it that operation is more reliable and more stable, and correspondingly, operation difficulty can also have been carried
It is high.In addition, the present invention uses but is not limited to peristaltic pump, gear pump, centrifugal pump of low discharge etc. are can also be, although the change energy
