Dynamic, the first conical plug 16 and first through hole 3 the conical surface is no longer bonded, and first through hole 3 is opened, while the second conical plug 18 overcomes
The elastic force of second compression spring 19 moves downward, and the conical surface of the second conical plug 18 and the second through-hole 4 is no longer bonded, and the second through-hole 4 is opened,
To make first through hole 3 be connected with the second through-hole 4, intraperitoneal hydrops drains into first through hole 3 through drainage catheter, then through first
Through-hole 3 and the second through-hole 4 flow into A liquid collecting cavities 2；As hydrops constantly flows into, the hydrops in A liquid collecting cavities 2 gradually increases, hydrops
Weight gradually increase, when hydrops weight is more than the first fixture block 9 to the clamping forces of A liquid collecting cavities 2, the first fixture block 9 can be by arc
Straight slot 8 squeezes in retraction blind hole 24, the first fixture block 9 no longer clamping A liquid collecting cavities 2, under the action of the weight of dead weight and hydrops, A
Liquid collecting cavity 2 moves downward until its bottom is pressed on supporting plate 6, and A liquid collecting cavities 2 depress time switch 29, and timer 28 records once
Time；Meanwhile the block 10 of its bottom also declines therewith after the decline of A liquid collecting cavities 2, after block 10 declines, montant 11 rotates shifting block
12 can stir the rotation of block 10, and to drive three liquid collecting cavities 2 to rotate synchronously, montant 11 drives three 2 rotation processes of liquid collecting cavity
In, 11 upper end of montant is gradually rotated from the most significant end of screw inclined plane 13 to least significant end, and montant 11 is gradually pushed by screw inclined plane 13,
After 120 degree of rotation, montant 11 is depressed into lowest point, and shifting block 12 is again below the height of 2 upper stopper 10 of A liquid collecting cavities, montant at this time
11, which are rotated further no longer three liquid collecting cavities 2 of drive, rotates, and three liquid collecting cavities 2 have rotated 120 degree, and montant 11 turns to screw inclined plane
It when 13 highest end position, pops up under the action of the 6th compression spring 33 and is contacted with screw inclined plane 13, the so cycle of montant 11 turns
It is dynamic.
During above-mentioned montant 11 drives three liquid collecting cavities 2 to rotate, the motion process and state of three liquid collecting cavities 2 are such as
Under：
A liquid collecting cavities 2 turn to drain location by hydrops position, and the first conical plug 16 thereon will under the action of the first compression spring 17
First through hole 3 is closed, and the third through-hole 5 and fourth hole 7 on A liquid collecting cavities 2 are opposite, due to third conical plug 20 and the 4th taper
22 small end mutual exclusions are filled in, so, under the action of repulsive magnetic force, third conical plug 20 overcomes the elastic force of third compression spring 21 to transport upwards
Dynamic, third conical plug 20 and third through-hole 5 the conical surface is no longer bonded, and third through-hole 5 is opened, while the 4th conical plug 22 overcomes
The elastic force of 4th compression spring 23 moves downward, and the conical surface of the 4th conical plug 22 and fourth hole 7 is no longer bonded, and fourth hole 7 is opened,
To make fourth hole 7 be connected with third through-hole 5, the hydrops in A liquid collecting cavities 2 is through third through-hole 5, fourth hole 7 and conduit stream
Enter in waste collecting device, which is more than liquid collecting speed；
B liquid collecting cavities 2 rotate 120 degree of positions to original C liquid collecting cavities 2 by drain location, when not rotating, the on B liquid collecting cavities 2
The pop-up of two fixture blocks 15 sticks into the head end i.e. least significant end in helicla flute 14 and positioned at helicla flute 14, with the rotation of B liquid collecting cavities 2, spiral shell
B liquid collecting cavities 2 are gradually lifted by spin slot 14 by the second fixture block 15, and the second fixture block 15 turns to the tail end i.e. most significant end of helicla flute 14
When, B liquid collecting cavities 2 are raised to extreme higher position, and the upper end is bonded with the upper end of shell 1, and the elastic clamping block on 1 side wall of shell is inside
Pop-up sticks into the arc-shaped slot 8 on B liquid collecting cavities 2, herein highly by the positioning of B liquid collecting cavities 2；The second through-hole 4 on B liquid collecting cavities 2
It is all closed with third through-hole 5；
C liquid collecting cavities 2 turn to liquid collecting position by original position, and the second through-hole 4 thereon is opened and connected, C relatively with first through hole 3
Liquid collecting cavity 2 starts to collect hydrops, waits after being collected into enough hydrops, and C liquid collecting cavities 2 decline, and montant 11 stirs three liquid collectings again
Chamber 2 rotates 120 degree, and C liquid collecting cavities 2 turn to drain location and start drain, and B liquid collecting cavities 2 turn to liquid collecting position and start liquid collecting, such as
This cycle realizes automatic ration drain.
The course of work for summarizing liquid collecting cavity 2 by taking A liquid collecting cavities 2 as an example is as follows：First in the liquid collecting of liquid collecting position, after liquid collecting is enough
Decline, montant 11 stirs liquid collecting cavity 2 and rotates 120 degree to drain location drain, and A liquid collecting cavities 2 are lifted by helicla flute 14 when rotating again
Elemental height is risen to, A liquid collecting cavities 2 turn to the liquid collecting of liquid collecting position when rotating again, so recycle.
It should be noted that when montant 11 is located at extreme lower position, whether liquid collecting cavity 2 declines or not, block 10, which is all higher than, to be dialled
The height of block 12, montant 11 cannot all drive liquid collecting cavity 2 to rotate, when montant 11 is located at extreme higher position, if liquid collecting cavity 2 does not decline,
Block 10 is still higher than the height of shifting block 12, and montant 11 cannot still drive liquid collecting cavity 2 to rotate, therefore only montant 11 is located at spiral shell
Montant 11 could drive three liquid collecting cavities 2 to rotate 120 degree when the liquid collecting cavity 2 of 13 lower section of rotation inclined-plane and liquid collecting position declines.
Here, the hydrops amount when liquid collecting cavity 2 of above-mentioned liquid collecting position is declined in the liquid collecting cavity 2 is defined as liquid measure threshold values,
When medical staff needs to obtain the drain age velocity of hydrops in abdominal cavity of patients, then some row time numbers that timer 28 records are checked
Value calculates the time difference between every adjacent two values, then fluid volume threshold values divided by time difference, that is, when being this section
Interior hydrops drainage speed, calculates the drainage speed in each period successively in chronological order, you can show that hydrops drains
The variation tendency of speed, the medical datas such as pathological characters or rehabilitation situation for diagnosing patient.
The present invention can adjust liquid measure threshold values by threaded rod 27, when needing that liquid measure threshold values is turned up, then rotary screwing thread bar 27
So that threaded rod 27 is moved inward, then threaded rod 27 push pressing plate 26 inwardly move, pressing plate 26 push the 5th compression spring 25 outer end to
The 5th compression spring 25 of interior motion compresses, then pressure increase of the 5th compression spring 25 to the first fixture block 9, card of first fixture block 9 to liquid collecting cavity 2
Clamp force increases, therefore more hydrops are needed in the liquid collecting cavity 2 of liquid collecting position just can make arc-shaped slot 8 push the contracting of the first fixture block 9
Enter to make liquid collecting cavity 2 decline in blind hole 24, i.e., liquid measure threshold values increases, and the maximum value of certain liquid measure threshold values is less than each fan-shaped chamber
The maximum capacity of room；When needing to turn down liquid measure threshold values, then rotary screwing thread bar 27 moves out, then the outer end of the 5th compression spring 25 pushes away
Dynamic pressure plate 26 moves out, and the decrement of the 5th compression spring 25 reduces, and the 5th compression spring 25 reduces the pressure of the first fixture block 9, therefore
