The purpose of this utility model and solve its technical matters and also adopt following technical measures to realize further.
Aforesaid in-vitro simulated ventricular system device, described external capsule 3 adopts rigidity medical material to make, and interior water pocket 4 adopts flexible biocompatible material to make.Because interior water pocket 4 is flexible, the interior water pocket 4 meeting overexpansion when patient's encephalic ventricular system hypertonia, its outer wall can extrude the pressure transducer 5 set by external capsule 3 inwall, produces alerting signal and is passed to outer controller 8.
Aforesaid in-vitro simulated ventricular system device, described first pipeline 6, second pipe 7 are all flexible duct.
Aforesaid in-vitro simulated ventricular system device, described first pipeline 6 other end is connected with Cerebrospinal Fluid in Patients drainage tube, and second pipe 7 other end is connected with cerebrospinal fluid gatherer.
By technique scheme, a kind of in-vitro simulated ventricular system apparatus structure of the utility model is simple, use is reliable, the pressure of energy Real-Time Monitoring patient encephalic ventricular system, and carries out the adjustment of drainage flow in vitro according to pressure change.Simultaneously the utility model avoids pressure transducer and contacts with the direct of cerebrospinal fluid, reduces the risk of intracranial infection.
In sum, a kind of in-vitro simulated ventricular system device of the utility model has significant progress technically, and has obvious good effect, is really a new and innovative, progressive, practical new design.

Embodiment
For further setting forth the utility model for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to in-vitro simulated its embodiment of ventricular system device, structure, feature and the effect thereof that the utility model proposes, be described in detail as follows.
Refer to Fig. 1, a kind of in-vitro simulated ventricular system device of the utility model comprises external capsule 3, interior water pocket 4, first pipeline 6, second pipe 7 and outer controller 8, and this interior water pocket 4 is arranged in external capsule 3, and this external capsule 3 inwall is installed on pressure transducer 5; This first pipeline 6 is communicated with interior water pocket 4 from top through external capsule 3, and this first pipeline 6 is installed on valve 1; This second pipe 7 passes from below through external capsule 3 and is communicated with interior water pocket 4, and this second pipe 7 is installed on lower valve 2; The function that this outer controller 8 connects valve 1, lower valve 2 and pressure transducer 5. wherein each parts is respectively as follows:
A. going up valve 1, for clamping the first pipeline 6 during needs, the first pipeline 6 being closed;
B. lower valve 2, for clamping second pipe 7 during needs, makes second pipe 7 close;
C. external capsule 3, adopts rigidity medical material to make.When the overexpansion of interior water pocket 4 (hypertonia of patient's encephalic ventricular system), pressure transducer 5 set by interior water pocket 4 outer wall extruding external capsule 3 inwall, produces alerting signal and is passed to outer controller 8;
D. interior water pocket 4, adopting flexible biocompatible material to make, for receiving by the cerebrospinal fluid of the first pipeline 6 through the drainage of upper valve 1, being in relaxed state when cerebrospinal fluid is emptying by lower valve 2;
E. pressure transducer 5, is located at external capsule 3 inwall, receives extruding when interior water pocket 4 over filling, produces alerting signal;
F. the first pipeline 6, flexible duct, for the collection of cerebrospinal fluid;
G. second pipe 7, flexible duct, for the discharge of cerebrospinal fluid;
H. outer controller 8, for accepting the alarm control signal of pressure transducer 5, simultaneously for controlling the unlatching of upper valve 1 and lower valve 2 and closing.
The workflow of the in-vitro simulated ventricular system device that the utility model proposes is as follows:
When this equipment is used for the drainage of Cerebrospinal Fluid in Patients, the first pipeline 6 is connected with Cerebrospinal Fluid in Patients drainage tube, and second pipe 7 is connected with cerebrospinal fluid gatherer.
During work, upper valve 1 is in opening, and now the first pipeline 6 is in conducting state, and lower valve 2 is in closed condition, and second pipe 7 is 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 according to patient profiles, can set the cerebrospinal fluid emptying time in this interior water pocket 4 by outer controller 8.Such as setting cerebrospinal fluid emptying time is 1h, and when after device work 1h, under the control of outer controller 8, upper valve 1 is closed, and adopts the method for extruding to be blocked by the first pipeline 6.Lower valve 2 is opened, second pipe 7 conducting, and the cerebrospinal fluid that this device is collected puts cerebrospinal fluid gatherer by second pipe 7 stream.After interior water pocket 4 is emptying, upper valve 1 is opened, and by the first pipeline 6 conducting, lower valve 2 is closed, and is blocked by second pipe 7, starts the cerebrospinal fluid collection work of a new round.
When conditions of patients changes, patient's cranium presses liter, cerebrospinal fluid accelerates to flow out, when not arriving the cerebrospinal fluid emptying time of outer controller 8 setting, interior water pocket 4 is positioned at the pressure transducer 5 of external capsule 3 inwall because of overexpansion extruding, produces alerting signal and is passed to outer controller 8, emergency opening lower valve 2 on the one hand, cerebrospinal fluid is discharged by second pipe 7, sends sound and light alarm signal on the one hand, remind medical personnel to note.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; for the utility model those skilled in the art; everyly utilize the utility model instructions and the simple modifications done by accompanying drawing content, be all in like manner included in scope of patent protection of the present utility model.
