Mouth is also connected with being arranged at the 3rd liquid outlet (due to blocking for the first plug receptacle 7, not shown in figure) of upper lid 1 and/or base 2
It is logical.
It can easily be seen that by the first interface 7, the first liquid outlet 34, the second liquid outlet and the 3rd liquid outlet are sequentially connected
Lead to.
Anti-siphon spheroid 4 is located in annular seal space 200, and is positioned in sphere installation hole 31, and anti-siphon spheroid 4 is used to block
Sphere installation hole 31.
Wherein, anti-siphon spheroid 4 can be glass spheres, and certainly, anti-siphon spheroid 4 can also be made up of other materials

It should be noted that in order to realize on closure of the anti-siphon spheroid 4 to sphere installation hole 31, sphere installation hole 31 with
The face that anti-siphon spheroid 4 coordinates can be taper surface or spherical.
Support member 5 is located in annular seal space 200, and is installed in support member mounting hole 33, and the top of support member 5 has support
Platform 51.
Spring leaf 6 is located in annular seal space 200, and the first end (left end shown in Fig. 1) of spring leaf 6 is overlapped in anti-siphon ball
Body 4, the second end (right-hand member shown in Fig. 1) of spring leaf 6 is overlapped in supporting table 5, also, the centre of spring leaf 6 has installation
Portion 61, spring leaf bearing 32 is carried out spacing by installation portion 61 to spring leaf 6.
It should be noted that spring leaf bearing 32 carries out spacing implementing form by installation portion 61 to spring leaf 6
It is various, it is clear in order to be laid out, it is follow-up to carry out citing introduction.
It is easily understood that because the first end of spring leaf 6 is overlapped in anti-siphon spheroid 4, therefore, the first of spring leaf 6
End can apply an active force in anti-siphon spheroid 4.In order that the first end of spring leaf 6 is reliably overlapped in anti-siphon spheroid 4, bullet
The first end of reed 6 can bond together with anti-siphon spheroid 4.
For the adjusting means in the drainage of cerebrospinal fluid system that this programme is provided, in actual installation, it will can be somebody's turn to do
Adjusting means is fixed on the head of patient by fixation kit, the second inlet is passed through the first drainage tube and the brain of patient
Room is connected, while making the 3rd liquid outlet be connected by the second drainage tube with drainage bag.
When the drainage system using the adjusting means for being provided with this programme offer is to implement extraventricular drainage art, from patient
The cerebrospinal fluid of encephalic outflow can be flowed to through the first drainage tube at the second inlet, and be successfully entered at the second inlet
In hollow structure 100.Afterwards, cerebrospinal fluid can be flowed at the first inlet 35 connected with the second inlet.
If the pressure value of patient's encephalic is less high, then, the pressure of the cerebrospinal fluid flowed at the first inlet 35 is general
The first end for being not above spring leaf 6 puts on the pressure of anti-siphon spheroid 4, at this moment, and anti-siphon spheroid 4 is in and can sealed completely
The position in stifled sphere installation hole 31, correspondingly, the cerebrospinal fluid flowed at the first inlet 35 can not be by sphere installation hole 31
Into in annular seal space 200, the cerebrospinal fluid in annular seal space 200 can not also be back to the first inlet 35 by sphere installation hole 31
Place.
When patient due to position chanP, cough, firmly etc. reason and when causing the pressure of encephalic to increase suddenly, flow to the
The first end that the pressure of cerebrospinal fluid at one inlet 35 will be typically higher than spring leaf 6 puts on the pressure of anti-siphon spheroid 4, this
When, anti-siphon spheroid 4 can be lifted in the presence of the making a concerted effort of the two power, i.e. anti-siphon spheroid 4 can relative to sphere installation
Hole 31 produces certain displacement, and anti-siphon spheroid 4, which can not be kept, can block the position of spheroid mounting hole 31 completely, accordingly
Ground, flows to the cerebrospinal fluid at the first inlet 35 and is entered by sphere installation hole 31 in annular seal space 200.Next, into close
Envelope chamber 200 in cerebrospinal fluid flow at the first liquid outlet 34 after, its can successively after the second liquid outlet and the 3rd liquid outlet from
Flowed out in annular seal space 200, afterwards, during the cerebrospinal fluid of outflow can enter drainage bag through the second drainage tube out of hollow structure 100 simultaneously
It is collected.
No matter under what circumstances it can easily be seen that, cerebrospinal fluid is only possible to the encephalic outflow from patient, and sequentially passes through the
One drainage tube, adjusting means and the second drainage tube enter in drainage bag, or cerebrospinal fluid can not enter annular seal space 200
Interior, it is never from adjusting means adverse current is into the first drainage tube and is back to patient's encephalic, i.e. cerebrospinal fluid and is merely able to unidirectionally
Flowing, therefore this programme preferably solves the reflux problem of cerebrospinal fluid, so that it is inverse due to cerebrospinal fluid to avoid the ventricles of the brain of patient
Flow and be infected, and then reliably protect the life security of patient.
In addition, it is necessary to, it is noted that be more than the of spring leaf 6 in the pressure for flowing to the cerebrospinal fluid at the first inlet 35
In the case that one end puts on the pressure of anti-siphon spheroid 4, if the difference of two pressure is bigger, what anti-siphon spheroid 4 was lifted
Highly, i.e. displacement of the anti-siphon spheroid 4 relative to sphere installation hole 31 will be bigger, correspondingly, enters at the first inlet 35
The flow velocity for entering the cerebrospinal fluid in annular seal space 200 will be faster.On the contrary, in the case where the difference of above-mentioned two pressure is smaller, resisting
The displacement of the height that siphon spheroid 4 is lifted, i.e. anti-siphon spheroid 4 relative to sphere installation hole 31 will be smaller, correspondingly, from
The flow velocity of the cerebrospinal fluid entered at first inlet 35 in annular seal space 200 will be slower.That is, entering according to flowing to first
The pressure of cerebrospinal fluid at liquid mouthful 35, adjusting means itself can adjust drainage speed, and the regulation process is without manually participating in.
It can be seen that, this programme preferably solves the reflux problem easily occurred in drainage process, also greatly simplify simultaneously
Care operation in drainage process.
As shown in Figures 2 and 3, in above-described embodiment, supporting table 51 can be spiralling step-like platform, spring leaf
6 the second end is adjusted to press at the different height of step-like platform.
It is understood that when the second end of spring leaf 6 is pressed at the different height of step-like platform, spring leaf 6
The pressure that puts on anti-siphon spheroid 4 of first end it is also different.
Specifically, if the height that presses on step-like platform of the second end of spring leaf 6 is higher, the of spring leaf 6
The pressure that one end is put on anti-siphon spheroid 4 is bigger；Conversely, then the first end of spring leaf 6 is put on anti-siphon spheroid 4
Pressure just it is smaller.For example, if anti-siphon spheroid 4, which is currently at, can not block the position of spheroid mounting hole 31 completely, that
, with the increase for the height that the second end of spring leaf 6 is pressed on step-like platform, the first end of spring leaf 6 puts on anti-
Pressure on siphon spheroid 4 can gradually increase, and the height that now anti-siphon spheroid 4 is lifted can be reduced gradually, therefore csf flow
Entering the flow velocity in annular seal space 200 can gradually reduce；The pressure increase put on when the first end of spring leaf 6 on anti-siphon spheroid 4
During to a certain threshold value, anti-siphon spheroid 4, which will be returned to, can block the position of anti-siphon spheroid 4 completely, and now cerebrospinal fluid will
It cannot be introduced into completely in annular seal space 200.
As can be seen that pressed on by the second end for adjusting spring leaf 6 at the different height of step-like platform, can be more
The pressure that easily and effectively first end of regulation spring leaf 6 is put on anti-siphon spheroid 4, so as to realize brain ridge more conveniently
The control and regulation of pressure and drainage speed in liquid drainage process.
It should be noted that the structure type of support member 5 is various, with reference to Fig. 2 and Fig. 3, to a kind of structure therein
Form carries out citing introduction.
As shown in Figures 2 and 3, support member 5 can include：First cylindrical structure 52 and the second hollow cylindrical structure
53.Wherein, the second cylindrical structure 53 is rotatablely installed in support member mounting hole 33, i.e., the outer wall of the second cylindrical structure 53 with
The inwall of support member mounting hole 33 is engaged.First cylindrical structure 52 is fixedly connected and is sheathed on the second cylindrical structure 53
It is interior, also, the bottom of the first cylindrical structure 52 is provided with adjustment portion 54 shown in Fig. 2, base 2 and corresponds to adjustment portion 54
Offer the handle hole 21 shown in Fig. 2.
Wherein, can be welding, certainly, the first cylinder between the first cylindrical structure 52 and the second cylindrical structure 53
Structure 52 can also be integrally formed with the second cylindrical structure 53 or be fixed by well-known to those skilled in the art other
Connected mode is attached, and can specifically be determined according to actual conditions, this is no longer going to repeat them.
Specifically, adjustment portion 54 can be inner hexagonal hole.
Step-like platform is arranged at the top of the second cylindrical structure 53, also, the second end of spring leaf 6 end face against
In the side wall of the first cylindrical structure 52.
Preferably, the end face at the second end of spring leaf 6 can be cambered surface.
When it is implemented, step-like platform can include highly different multi-stage stairs structure, multi-stage stairs structure along
The circumference on the top of the second cylindrical structure 53 is arranged by height size order.For example, the step-like platform can include
18 grades of ledge structures, wherein, the minimum first order ledge structure of height correspond to 30mmH2O cerebrospinal pressure force value, height
Second small second level ledge structure correspond to 40mmH2O cerebrospinal pressure force value, the 3rd small third level ledge structure of height
It correspond to 50mmH2O cerebrospinal pressure force value, often increases one-level step, and corresponding cerebrospinal pressure force value is increased by 10mmH2O is high
Degree the 18th grade of step of highest correspond to 200mmH2O cerebrospinal pressure force value.Can according to the result that finite element simulation is modeled
Know, the corresponding relation that the first end of spring leaf 6 is put between the pressure on anti-siphon spheroid 4 and the height of ledge structure is met
Hooke's law, therefore, it can by making the second end of spring leaf 6 press on the ledge structure of different height come more accurately
The pressure that the first end of control spring leaf 6 is put on anti-siphon spheroid 4.
It should be noted that highly between the 18th grade of ledge structure of minimum first order ledge structure and height highest
The transition bench that one end can be set smooth.
, can when the second end for needing to make spring leaf 6 is pressed at the different height on step-like platform in the present embodiment
So that special hexagonal regulation spanner coordinates through handle hole 21 with adjustment portion 54, hexagonal regulation spanner is then rotated, to pass through
The rotation of hexagonal regulation spanner drives the first cylindrical structure 52 to rotate, correspondingly, and the second cylindrical structure 53 also can be with the
The rotation of one cylindrical structure 52 and rotate in the support member mounting hole 33, by controlling the first cylindrical structure 52 exactly
The anglec of rotation, and the end face at the second end of spring leaf 6 is resisted against the side-walls of the correspondence position of the first cylindrical structure 52, you can
The second end of spring leaf 6 is set reliably to press on the ledge structure of setting height, therefore the first end of spring leaf 6 puts on anti-rainbow
The pressure inhaled on spheroid 4 can also be adjusted accordingly, so, flowed into the flow velocity of the cerebrospinal fluid of annular seal space 200 and can also be adjusted
It is whole, also, when support member 5 is using said structure, the structure of the adjusting means is relatively simple.
It is emphasized that the gap between the second cylindrical structure 53 and support member mounting hole 33 should be in suitable
In the range of, if gap between the two is excessive, the reliable installation of the second cylindrical structure 53 can not be ensured, if between the two
Gap is too small, then the second cylindrical structure 53 will be difficult to rotate in support member mounting hole 33.
It should be noted that to carry out spacing way of realization to spring leaf 6 by installation portion 61 various for spring leaf bearing 32,
The concrete implementation form to two kinds therein is illustrated below.
In a kind of way of realization, spring leaf 6 can offer through hole, and installation portion 61 is to turn over the connection located at through hole edge
Plate.Specifically, connecting plate can be bending plate.The top of spring leaf bearing 32 offers connecting hole, and connecting plate is slideably inserted
