Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, it is specific to a kind of adjustable pressure control external ventricle drainage device proposed according to the present invention
Embodiment, structure, feature and its effect, detailed description is as follows.
The present invention includes the right angle bending pipeline of three cerebrospinal fluid trickling pipelines and a control pressure, three csf flows
Dropping down pipeline respectively is first pipe 1, second pipe 2 and third pipeline 3, and the right angle bending pipeline of a control pressure is the 4th pipe
Road 4.One end of first pipe is connect 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 third pipeline is vertically fixed in the bottom of first pipe, and lower end is connected with drainage bag 5.4th pipeline water
The port of flat part is vertically fixed in third pipeline；Cavity between first pipe and the 4th pipe level part is second pipe
2, and the middle part of second pipe is connected with the water outlet 6 of first pipe；One end phase of the top of third pipeline and second pipe
Connection, the 4th pipe level part and second pipe share an elastic film 7, when the water column pressure in the 4th pipeline is sufficiently large
When, this elastic film is close to first pipe water outlet.The vertical portion filled water of 4th pipeline, outer wall have scale to show water
Pressure.
Second pipe is internally provided with dentalation, facilitates elastic film closing second pipe.
It is provided with scale on the outside of 4th pipeline vertical portion tube wall, can show the pressure at film.
When cerebrospinal fluid is lower than the pressure of water at elastic film to the pressure of elastic film in first pipe, elastic film envelope
Close first pipe water outlet, no drainage of cerebrospinal fluid；When cerebrospinal fluid is higher than Thin Elastic for the pressure of elastic film in first pipe
At film when the pressure of water, elastic film is moved down, and water outlet is open, and cerebrospinal fluid flows to third through second pipe from first 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
Change the control to pressure at elastic film, pressure control range is 0-20 centimeter water column.
Further, the diameter of water outlet is 2-5mm, and the diameter of second pipe is 1-2mm.
The present invention operates in such a way:
When the present invention is used for the drainage of Cerebrospinal Fluid in Patients, the 4th pipeline scale part is placed vertically, is injected a certain amount of
Water or physiological saline control certain pressure, close elastic film by first pipe water outlet.First pipe and Cerebrospinal Fluid in Patients
Drainage tube connection, third pipeline are connect with drainage bag.When there is cerebrospinal fluid outflow, csf flow is through first pipe, when the first pipe
When the pressure of cerebrospinal fluid is greater than the pressure of water at the 4th pipeline film in road, film is moved down, and first pipe water outlet is open,
Csf flow flows into drainage bag through second pipe using third pipeline.When cerebrospinal pressure decline is (indirect in first pipe
Reflect intracranial pressure decline), lower than when the pressure of water, under the pressure effect of water, elastic film is again at the 4th pipeline film
First pipe water outlet is closed, cerebrospinal fluid cannot flow into drainage bag.
The present invention can effectively prevent excessively draining, and reflect patient's intracranial pressure indirectly, and by cerebrospinal pressure in first pipe
Power is maintained at certain level, realizes that adjustable pressure controls external ventricle drainage.And the present invention is not by patient body position and drainage
The influence of bag height, it is greatly convenient to provide for curative activity.
