4 be open state.
Schematic diagram of internal structure of the present invention as shown in Figure 1, elastic switch 4 is under no external force for shown in Fig. 1
Tight position, that is, closed state can be washed open by the physiological saline from right side.The drop monitoring device 5 is mounted in opposite directions
6 two sides of hydrops side one-way pump, unobstructed to drop monitoring device 5 when drop does not pass through, drop monitoring device 5 export low level,
Drop monitoring device 5 is blocked when drop passes through, drop monitoring device 5 exports high level, an as dropping liquid, by described
Computer control chip 20 records liquid drop speed；If dripping speed lower than minimum drop set by speed setting knob 13 is dripped by drop,
Computer control chip 20 starts autompulse cleaning procedure, specific autompulse cleaning procedure are as follows: computer control chip 20 is controlled
Motor 25 processed works, and motor 25 drives driving gear 10 to rotate, and driving gear 10 is rotated with moving gear 9, and gear 9 drives connecting rod 8
Movement moves synchronous piston 7 above and below.
Wherein, when synchronous piston 7 pushes up, as shown in figure 5, for head-end drainage tube bath status diagram；This
When, physiological saline washes elastic switch 4 open, and due to the blocking of physiological saline side one-way cock, physiological saline is injected into drainage tube
It is rinsed.Physiology salt water cavity B22 attracts physiological saline to be filled into physiology salt water cavity B22 due to suction function；Opposite side, product
Liquid is flowed into fluid collection chamber D24 by hydrops side one-way cock in sap cavity C23.
Wherein, when synchronous piston 7 pushes down on, as shown in fig. 6, being the status diagram that absorbs water from head end drainage tube；This
When, elastic switch 4 is closed, and due to the blocking of hydrops side one-way cock, hydrops is drawn into fluid collection chamber C23.In fluid collection chamber D24
Liquid is forced into liquid storing bag；Opposite side, the physiological saline in physiology salt water cavity B22 pass through physiological saline side one-way cock and flow into
In physiology salt water cavity A21, once flushing is completed.
After completing setting washing time, into monitoring state.If reaching the minimum drop drop speed of setting, enters and normally draw
Flow monitoring state；It is such as still below minimum drop drop speed, then is again introduced into flushing state.Number is by setting total flushing time repeatedly
Number determines.If reaching total washing time, still inadequate drainage, then start warning device of the invention, including alarm lamp 18 dodges
Bright, 19 ring of buzzer prompts medical staff's manual maintenance drainage device.
The principle of the invention are as follows: by monitoring drainage tube cerebrospinal fluid drop speed automatically, it is ensured that the normal drainage of cerebrospinal fluid；When brain ridge
After drop speed drops to setting minimum value, start autompulse cleaning procedure, is cleaned according to setting scavenging period, it is rear automatic
Continue to monitor.If still obstructed, according to setting wash number, continue to clean.After setting wash number, device alarm,
Remind medical care manual adjustment.
As shown in figure 4, being normal drainage monitoring state schematic diagram of the present invention；Elastic switch 4 is in off state, outside cerebrospinal fluid
The head end of drainage tube connects fluid collection chamber C23 by water conservancy diversion interface tube 1, is connected by hydrops side one-way cock with fluid collection chamber D24, leads to
Liquid storage bag interface 2 is crossed to be connected with liquid storing bag.Wherein, when external cerebrospinal fluid drop speed is normal, the steel ball in the one-way cock of hydrops side exists
In one-way cock bottom under gravity, hydrops flows into liquid storage by fluid collection chamber D24, liquid storage bag interface 2 from one-way cock gap
Bag.
As shown in figure 5, for head-end drainage tube of the present invention bath status diagram；It is pressed upwards on, is pushed away by synchronous piston 7
Compression elasticity switch 4 is open state, and physiological saline is upward by water conservancy diversion interface tube 1 from physiology salt water cavity A21, is carried out to drainage tube
It rinses.Wherein, the steel ball in the one-way cock of physiological saline side falls into bottom slot, blocks valve；Opposite side is made in synchronous piston 7
Under, hydrops side one-way cock is open, and liquid is flowed in fluid collection chamber D24 by hydrops side one-way cock in fluid collection chamber C23.
As shown in fig. 6, to be of the invention from head end drainage tube water suction status diagram；It is pushed down on by synchronous piston 7, liquid
Body sucks in fluid collection chamber C23 out of head end drainage tube by water conservancy diversion interface tube 1.Wherein, elastic switch 4 is in off state, physiology
Under suction, physiological saline flows to physiology salt water cavity A21 from physiology salt water cavity B22 to brine side one-way cock；Opposite side, hydrops
Steel ball in the one-way cock of side moves up, and hydrops side one-way cock is closed, and guarantees that liquid can not be to fluid collection chamber in fluid collection chamber D24
C23 adverse current, completes negative-pressure ward.
It is understood that being merely to illustrate the present invention above with respect to specific descriptions of the invention and being not limited to this
Technical solution described in inventive embodiments, those skilled in the art should understand that, still the present invention can be carried out
Modification or equivalent replacement, to reach identical technical effect；As long as meet use needs, all protection scope of the present invention it
It is interior.
