Capsule 3 connects with interior water pocket 4, and is installed on valve 1 on first pipeline 6；The one end of second pipe 7 passes from below through external capsule 3
Connected with interior water pocket 4, and lower valve 2 is installed on the second pipe 7；The outer controller 8 connects valve 1, lower valve 2 respectively
And pressure sensor 5.
The object of the invention to solve the technical problems is also further realized using following technical measures.
Foregoing in-vitro simulated ventricular system device, the external capsule 3 are made of rigid medical material, and interior water pocket 4 uses
Flexible biocompatible material is made.Because interior water pocket 4 is flexibility, when patient's encephalic ventricular system hypertonia, interior water pocket 4 can be excessive
Expansion, its outer wall can extrude the pressure sensor 5 set by the inwall of external capsule 3, produce alarm signal and are transferred to outer controller 8.
Foregoing in-vitro simulated ventricular system device, first pipeline 6, second pipe 7 are all flexible duct.
Foregoing in-vitro simulated ventricular system device, the other end of the first pipeline 6 are connected with Cerebrospinal Fluid in Patients drainage tube,
The other end of second pipe 7 is connected with cerebrospinal fluid collector.
By above-mentioned technical proposal, a kind of in-vitro simulated ventricular system apparatus structure of the present invention is simple, uses reliable, energy reality
When monitor the pressure of patient's encephalic ventricular system, and carry out according to pressure change the adjustment of drainage flow in vitro.The present invention simultaneously
Avoid pressure sensor from being contacted with the direct of cerebrospinal fluid, reduce the risk of intracranial infection.
In summary, in summary, a kind of in-vitro simulated ventricular system device of the present invention technically has significant progress,
And there is obvious good effect, it is really a new and innovative, progressive, practical new design.

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 in-vitro simulated its embodiment of ventricular system device proposed by the present invention, structure, spy
Sign and its effect, describe in detail as after.
Referring to Fig. 1, a kind of in-vitro simulated ventricular system device of the present invention include external capsule 3, interior water pocket 4, the first pipeline 6,
Second pipe 7 and outer controller 8, the interior water pocket 4 are arranged in external capsule 3, and the inwall of external capsule 3 is installed on pressure sensor 5；This
One pipeline 6 connects from above through external capsule 3 with interior water pocket 4, and is installed on valve 1 on first pipeline 6；The second pipe 7
Pass from below through external capsule 3 to connect with interior water pocket 4, and lower valve 2 is installed on the second pipe 7；The outer controller 8 connects respectively
Upper valve 1, lower valve 2 and pressure sensor 5.
The function of wherein each part is as follows：
A. upper valve 1, the first pipeline 6 is clamped during for needing, closing the first pipeline 6；
B. lower valve 2, second pipe 7 is clamped during for needing, closing second pipe 7；
C. external capsule 3, it is made of rigid medical material.When the interior water pocket 4 excessively expansion (pressure of patient's encephalic ventricular system
It is too high), pressure sensor 5 set by the interior outer wall of the water pocket 4 extruding inwall of external capsule 3, produce alarm signal and be transferred to outer controller 8；
D. interior water pocket 4, is made of flexible biocompatible material, for receiving the brain drained by the first pipeline 6 by upper valve 1
Spinal fluid, relaxed state is in when cerebrospinal fluid is emptied by lower valve 2；
E. pressure sensor 5, located at the inwall of external capsule 3, extruding is received when interior 4 over filling of water pocket, produces alarm signal；
F. the first pipeline 6, flexible duct, the collection for cerebrospinal fluid；
G. second pipe 7, flexible duct, the discharge for cerebrospinal fluid；
H. outer controller 8, for receiving the alarm control signal of pressure sensor 5, while for control valve 1 and under
The unlatching of valve 2 and closure.
The workflow of in-vitro simulated ventricular system device proposed by the present invention：
When the equipment is used for the drainage of Cerebrospinal Fluid in Patients, the first pipeline 6 is connected with Cerebrospinal Fluid in Patients drainage tube, second pipe
7 are connected with cerebrospinal fluid collector.
Upper valve 1 is in opening during work, and now the first pipeline 6 is in opening, and lower valve 2, which is in, closes shape
State, second pipe 7 are in blocking state, and interior water pocket 4 is in relaxed state, and cerebrospinal fluid enters interior water pocket 4 by the first pipeline 6.
Under normal operation, doctor, by outer controller 8, can set the brain in the interior water pocket 4 according to patient profiles
Spinal fluid emptying time.Such as cerebrospinal fluid emptying time is set as 1h, and after device works 1h, under the control of outer controller 8, on
Valve 1 is closed, and is blocked the first pipeline 6 using the method for extruding.Lower valve 2 is opened, and second pipe 7 turns on, and the device is collected
Cerebrospinal fluid cerebrospinal fluid collector is put by the stream of second pipe 7.After interior water pocket 4 empties, upper valve 1 is opened, by the first pipeline 6
Conducting, lower valve 2 are closed, second pipe 7 are blocked, and start the cerebrospinal fluid collection work of a new round.
When conditions of patients changes, patient's cranium pressure rises, and cerebrospinal fluid accelerates outflow, the brain not set to outer controller 8
During spinal fluid emptying time, interior water pocket 4 produces alarm signal because excessively expansion extruding is located at the pressure sensor 5 of the inwall of external capsule 3,
Outer controller 8 is transferred to, one side emergency opening lower valve 2, cerebrospinal fluid is discharged by second pipe 7, on the one hand sends sound
Visual alarm, medical personnel are reminded to pay attention to.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the scope of the invention, for this hair
For bright those skilled in the art, every simple modifications made by using description of the invention and accompanying drawing content, together
Reason is included within the scope of the present invention.
