Through-hole is opposite, the first conical plug 4 and the second conical plug 8 back movement under the action of repulsive magnetic force, the first conical through-hole 3 and
Two conical through-holes 7 are opened and are connected, and the liquid collecting cavity 2 of left end starts to collect hydrops, until it is left to be collected into lever 1 after enough hydrops
End declines, and the liquid collecting cavity 2 of left end starts drain, and the rising of liquid collecting cavity 2 of right end starts to collect hydrops, while sliding block 18 is from sliding slot 17
Right end slides into left end, depresses time switch 21 on the way, and timer 20 records a time again, so recycles, two liquid collectings
Chamber 2 replaces liquid collecting drain, and timer 20 records a time when realizing automatic ration drain, and switching every time.
In the above process, relative to the weight of the weight and sliding block 18 of hydrops in liquid collecting cavity 2, the mutual exclusion between each conical plug
The influence that magnetic force rotates lever 1 is negligible.
In this specification the following contents, hydrops amount when above-mentioned lever 1 is rotated in liquid collecting cavity 2 is defined as liquid measure valve
Value.
When medical staff needs to obtain the drain age velocity of hydrops in abdominal cavity of patients, then some of the record of timer 20 are checked
Time numerical value is arranged, calculates the time difference between every adjacent two values, then fluid volume threshold values divided by time difference, i.e.,
For the hydrops drainage speed in this time, the drainage speed in each period is calculated successively in chronological order, you can obtain
The variation tendency of hydrops drainage speed, the medical datas such as pathological characters or rehabilitation situation for diagnosing patient.
The present invention can adjust liquid measure threshold values by installing the clump weight 19 of different number additional on sliding block 18, when needing to be turned up
When liquid measure threshold values, then suitable clump weight 19 is installed additional on sliding block 18, top is in just in the collection of liquid collecting after installing clump weight 19 additional
More hydrops are needed in sap cavity 2 just can be such that lever 1 rotates, i.e., liquid measure threshold values increases, and the maximum value of certain liquid measure threshold values is less than
The maximum capacity of each sector-shaped compartments；When needing to turn down liquid measure threshold values, then suitable clump weight 19 is removed from sliding block 18, is torn open
Just needing less hydrops that lever 1 can be made to rotate in the liquid collecting cavity of liquid collecting 2 in top after appropriate clump weight 19 down, i.e. liquid
Threshold values is measured to reduce.
In the time interval that lever 1 twice rotates switching liquid collecting cavity 2, the company of the present apparatus and waste collecting device can be disconnected
It connects, then tablet 23 is fixed vertically or is mounted on patient's loins or leg or wheelchair etc., then patient can be in this time
Sick bed is left in interval and carries out certain activity or recovery exercise etc., is conducive to the impatient psychology of reduction of patient and physical function
Restore；Liquid measure threshold values tune it is higher, it is longer for the duration of patient activity, liquid measure threshold values tune it is lower, sector-shaped compartments switching
It is more frequent, the case where time numerical value of record is also more intensive, and the drainage speed obtained is also more accurate, and medical staff can be according to patient
Adjust liquid measure threshold values.
The present invention can be arranged as required to manual leakage fluid dram, at the end of drainage, be removed from drainage catheter by medical staff
On remove the present apparatus, empty the hydrops in it, timer 20 then emptied into reset, to the present apparatus carry out cleaning and sterilizing storage,
