Embodiment
Further to illustrate the present invention to reach the technological means and effect that predetermined goal of the invention is taken, below in conjunction with
Accompanying drawing and preferred embodiment, to according to a kind of adjustable Stress control external ventricle drainage device proposed by the present invention, its is specific
Embodiment, structure, feature and its effect, are described in detail as after.
The present invention includes three cerebrospinal fluid trickling pipelines and the right angle bending pipeline of a control pressure, three csf flows
It is the first pipeline 1, the pipeline 3 of second pipe 2 and the 3rd respectively to drop down pipeline, and the right angle bending pipeline of a control pressure is the 4th pipe
Road 4.One end of first pipeline is connected with the drainage of cerebrospinal fluid pipe against ventricles of the brain end, and the other end is vertically fixed in the perpendicular of the 4th pipeline
Straight part；The upper end of 3rd pipeline is vertically fixed in the bottom of the first pipeline, and lower end is connected with drainage bag 5.4th pipeline water
The port of flat part is vertically fixed in the 3rd pipeline；Cavity between first pipeline and the 4th pipe level part is second pipe
2, and the middle part of second pipe is connected with the delivery port 6 of the first pipeline；The top of 3rd pipeline and one end phase of second pipe
Connection, the 4th pipe level part shares an elastic film 7 with second pipe, when the water column pressure in the 4th pipeline is sufficiently large
When, this elastic film is close to the first pipe water outlet.The vertical portion filled water of 4th pipeline, its outer wall has scale to show water
Pressure.
Second pipe is internally provided with dentalation, contributes to elastic film to close second pipe.
Scale is provided with the outside of 4th pipeline vertical portion tube wall, the pressure at film can be shown.
When cerebrospinal fluid is less than the pressure of water at elastic film to the pressure of elastic film in the first pipeline, elastic film envelope
Close the first pipe water outlet, no drainage of cerebrospinal fluid；When cerebrospinal fluid is higher than Thin Elastic for the pressure of elastic film in the first pipeline
At film during the pressure of water, elastic film is moved down, and delivery port is opened, and cerebrospinal fluid flows to the 3rd from the first pipeline through second pipe
Pipeline, and then enter drainage bag.
The present invention, can be by changing the water-column in the 4th pipeline according to pressure at the pressure itself control film of water
To change the control to pressure at elastic film, pressure control range is 0-20 centimeter water columns.
Further, a diameter of 2-5mm of delivery port, a diameter of 1-2mm of second pipe.
The present invention so works：
When the present invention is used for into the drainage of Cerebrospinal Fluid in Patients, the 4th pipeline scale part is placed vertically, injected a certain amount of
Water or physiological saline, control certain pressure, elastic film is closed the first pipe water outlet.First pipeline and Cerebrospinal Fluid in Patients
Drainage tube is connected, and the 3rd pipeline is connected with drainage bag.When there is cerebrospinal fluid outflow, csf flow is through the first pipeline, when the first pipe
When the pressure of cerebrospinal fluid is more than the pressure of water at the 4th pipeline film in road, film is moved down, and the first pipe water outlet is opened,
Csf flow is flowed into drainage bag by the 3rd pipeline again through second pipe.When cerebrospinal pressure declines (indirectly in the first pipeline
Reflect that intracranial pressure declines), less than during the pressure of water, under the pressure effect of water, elastic film is again at the 4th pipeline film
By the closing of the first pipe water outlet, cerebrospinal fluid cannot flow into drainage bag.
The present invention can effectively prevent excessive drainage, reflection patient's intracranial pressure, and by cerebrospinal pressure in the first pipeline indirectly
Power is maintained at certain level, realizes adjustable Stress control external ventricle drainage.And the present invention is not by patient body position and drainage
The influence of bag height, provides for curative activity and greatly facilitates.
The above described is only a preferred embodiment of the present invention, any formal limitation not is done to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
