When the drainage device is used, the shell 1 needs to be vertically placed or hung, the first through hole 3 is communicated with a liquid outlet of the drainage catheter, the fourth through hole 7 is connected with a waste liquid collecting device through the catheter, after connection, the timer 28 is started to start timing, and the micro motor 30 is started at the same time; in the initial state, the second through hole 4 and the first through hole 3 on one of the liquid collecting cavities 2 are opposite, so that the use principle and the process are convenient to introduce, the position of the liquid collecting cavity 2 is called a liquid collecting position, the liquid collecting cavity 2 is called an A liquid collecting cavity 2, the other two liquid collecting cavities 2 are sequentially called a B liquid collecting cavity 2 and a C liquid collecting cavity 2 along the anticlockwise direction, when the A liquid collecting cavity 2 is in the liquid collecting position, the third through hole 5 and the fourth through hole 7 on the B liquid collecting cavity 2 are opposite, and the position of the B liquid collecting cavity 2 at the moment is called a liquid discharging position.
When drainage is started, the upper end of the liquid collecting cavity 2A is attached to the upper end of the shell 1, a first clamping block 9 at a liquid collecting position is inwards popped and clamped into an arc-shaped through groove 8 in the outer wall of the liquid collecting cavity 2A under the action of a fifth pressure spring 25 to position the liquid collecting cavity 2A at the height, a stop block 10 on the liquid collecting cavity 2A is higher than a shifting block 12 on a vertical rod 11, the vertical rod 11 cannot drive the liquid collecting cavity 2 to rotate when rotating, and the stop block 10 on the liquid collecting cavity 2A and the highest end of a spiral inclined surface 13 are located at the same circumferential position; at the moment, a third conical plug 20 in a third through hole 5 in the liquid collecting cavity A2 is attached to and tightly pressed against a conical surface of the third through hole 5 under the action of the elastic force of a third pressure spring 21, and the third through hole 5 is closed; meanwhile, the first through hole 3 and the second through hole 4 are opposite, and the small ends of the first conical plug 16 and the second conical plug 18 in the through holes are mutually exclusive, so under the action of mutually exclusive magnetic force, the first conical plug 16 overcomes the elastic force of the first pressure spring 17 to move upwards, the conical surfaces of the first conical plug 16 and the first through hole 3 are not attached any more, the first through hole 3 is opened, the second conical plug 18 overcomes the elastic force of the second pressure spring 19 to move downwards, the conical surfaces of the second conical plug 18 and the second through hole 4 are not attached any more, the second through hole 4 is opened, so that the first through hole 3 and the second through hole 4 are communicated, accumulated liquid in the abdominal cavity is discharged to the first through hole 3 through a drainage catheter and then flows into the liquid collecting cavity A2 through the first through hole 3 and the second through hole 4; the accumulated liquid in the liquid collecting cavity A2 is gradually increased along with the continuous inflow of the accumulated liquid, the weight of the accumulated liquid is gradually increased, when the weight of the accumulated liquid is larger than the clamping force of the first clamping block 9 on the liquid collecting cavity A2, the first clamping block 9 can be extruded by the arc-shaped through groove 8 and retracted into the blind hole 24, the liquid collecting cavity A2 is not clamped by the first clamping block 9, the liquid collecting cavity A2 moves downwards under the action of the self weight and the weight of the accumulated liquid until the bottom of the liquid collecting cavity A is pressed on the supporting plate 6, the liquid collecting cavity A2 presses the timing switch 29, and the timer 28 records the time; meanwhile, the stop dog 10 at the bottom of the liquid collecting cavity A2 descends along with the liquid collecting cavity A, after the stop dog 10 descends, the vertical rod 11 rotates the shifting block 12 to shift the stop dog 10 to rotate, so that the three liquid collecting cavities 2 are driven to rotate synchronously, the vertical rod 11 drives the three liquid collecting cavities 2 to rotate, the upper end of the vertical rod 11 gradually rotates from the highest end to the lowest end of the spiral inclined plane 13, the vertical rod 11 is gradually pressed downwards by the spiral inclined plane 13, after the vertical rod 11 rotates for 120 degrees, the vertical rod 11 is pressed to the lowest position, the shifting block 12 is lower than the height of the stop dog 10 on the liquid collecting cavity A2 again, the vertical rod 11 continues to rotate and does not drive the three liquid collecting cavities 2 to rotate any more, the three liquid collecting cavities 2 rotate for 120 degrees, when the vertical rod 11 rotates to the highest end position of the spiral inclined plane 13, the vertical rod.
In the process that the vertical rod 11 drives the three liquid collecting cavities 2 to rotate, the motion process and the state of the three liquid collecting cavities 2 are as follows:
the liquid collecting cavity 2A rotates from the liquid collecting position to the liquid discharging position, the first conical plug 16 on the liquid collecting cavity A seals the first through hole 3 under the action of the first pressure spring 17, the third through hole 5 on the liquid collecting cavity 2A is opposite to the fourth through hole 7, because the small ends of the third conical plug 20 and the fourth conical plug 22 are mutually exclusive, therefore, under the action of the repulsive magnetic force, the third conical plug 20 overcomes the elastic force of the third pressure spring 21 to move upwards, the conical surfaces of the third conical plug 20 and the third through hole 5 are not attached any more, the third through hole 5 is opened, meanwhile, the fourth conical plug 22 moves downwards against the elastic force of the fourth pressure spring 23, the conical surfaces of the fourth conical plug 22 and the fourth through hole 7 are not attached any more, the fourth through hole 7 is opened, the fourth through hole 7 is communicated with the third through hole 5, the accumulated liquid in the liquid collecting cavity A2 flows into the waste liquid collecting device through the third through hole 5, the fourth through hole 7 and the guide pipe, and the liquid discharging speed is higher than the liquid collecting speed;
the liquid collecting cavity 2B rotates 120 degrees from the liquid discharging position to the original liquid collecting cavity 2C, when the liquid collecting cavity 2B does not rotate, a second fixture block 15 on the liquid collecting cavity 2B is popped out and clamped into the spiral groove 14 and is positioned at the head end, namely the lowest end, of the spiral groove 14, the spiral groove 14 gradually lifts the liquid collecting cavity 2B through the second fixture block 15 along with the rotation of the liquid collecting cavity 2B, when the second fixture block 15 rotates to the tail end, namely the highest end, of the spiral groove 14, the liquid collecting cavity 2B is lifted to the highest position, the upper end of the liquid collecting cavity B is attached to the upper end of the shell 1, an elastic fixture block on the side wall of the shell 1 is popped inwards and clamped into an arc-shaped through groove; the second through hole 4 and the third through hole 5 on the liquid collecting cavity 2 are both closed;
the C collects the liquid chamber 2 and rotates to a liquid position by the original position, the second through hole 4 and the first through hole 3 on it are opened relatively and put through, the C collects the liquid chamber 2 and begins to collect the hydrops, after collecting the sufficient hydrops, the C collects the liquid chamber 2 and descends, the montant 11 stirs three liquid chamber 2 once more and rotates 120 degrees, the C collects the liquid chamber 2 and rotates to the liquid position and begins to expel liquid, the B collects the liquid chamber 2 and rotates to the liquid position and begins to collect liquid, so circulation realizes automatic quantitative liquid discharge.
The working process of the liquid collecting cavity 2 is summarized by taking the liquid collecting cavity 2A as an example as follows: at first collect liquid in album liquid position, decline behind the album liquid capacity, montant 11 stirs collection liquid chamber 2 and rotates 120 degrees to flowing back liquid position flowing back, and A collection liquid chamber 2 is lifted to initial height by spiral groove 14 when rotating once more, and A collection liquid chamber 2 rotates to collection liquid position collection liquid when rotating once more, and so circulation.
It should be noted that, when the vertical rod 11 is located the lowest position, no matter whether the liquid collecting cavity 2 descends, the stopper 10 is higher than the height of the shifting block 12, the vertical rod 11 cannot drive the liquid collecting cavity 2 to rotate, when the vertical rod 11 is located the highest position, if the liquid collecting cavity 2 does not descend, the stopper 10 is still higher than the height of the shifting block 12, the vertical rod 11 still cannot drive the liquid collecting cavity 2 to rotate, and therefore the vertical rod 11 can only drive the three liquid collecting cavities 2 to rotate 120 degrees when the vertical rod 11 is located below the spiral inclined plane 13 and the liquid collecting cavity 2 at the liquid collecting position descends.
Here, the amount of effusion in the liquid collecting cavity 2 when the liquid collecting cavity 2 at the above-mentioned liquid collecting position descends is defined as a liquid amount threshold value, when the medical staff needs to obtain the liquid discharge speed of the effusion in the abdominal cavity of the patient, a series of time values recorded by the timer 28 are checked, the time difference value between every two adjacent values is calculated, then the time difference value is divided by the liquid amount threshold value, namely, the effusion drainage speed in this period of time, the drainage speed in each time period is calculated in sequence according to the time sequence, and the change trend of the effusion drainage speed can be obtained for diagnosing the medical data such as pathological features or rehabilitation conditions of the patient.
According to the invention, the liquid level threshold value can be adjusted through the threaded rod 27, when the liquid level threshold value needs to be increased, the threaded rod 27 is screwed to enable the threaded rod 27 to move inwards, the threaded rod 27 pushes the pressing plate 26 to move inwards, the pressing plate 26 pushes the outer end of the fifth pressure spring 25 to move inwards to compress the fifth pressure spring 25, the pressure of the fifth pressure spring 25 on the first fixture block 9 is increased, the clamping force of the first fixture block 9 on the liquid collection cavity 2 is increased, so that more accumulated liquid is needed in the liquid collection cavity 2 at the liquid collection position, the arc-shaped through groove 8 can push the first fixture block 9 to retract into the blind hole 24, and the liquid collection cavity 2 is lowered, namely, the threshold liquid level is increased, and the maximum value of the liquid level threshold value is lower; when liquid volume threshold value need be transferred down, then revolve to twist threaded rod 27 and outwards move, then the outer end of fifth pressure spring 25 promotes clamp plate 26 and outwards moves, and the compression capacity of fifth pressure spring 25 reduces, and fifth pressure spring 25 reduces to the pressure of first fixture block 9, thereby need still less hydrops just to make the arc lead to groove 8 to promote in the collection liquid chamber 2 of collection liquid position first fixture block 9 retraction blind hole 24 and make collection liquid chamber 2 descend, and liquid volume threshold value reduces promptly.
In the time interval between two times of shell rotation liquid drainage, the device can be disconnected from the waste liquid collecting device, then the device is hung at the waist or the leg of a patient or a wheelchair, and the patient can leave a sickbed in the time interval to perform certain activities or recover exercises and the like, so that the recovery of the psychological and physical functions of the patient, which are irritated, can be relieved; the higher the liquid volume threshold value is adjusted, the longer the time for a patient to move, the lower the liquid volume threshold value is adjusted, the more frequently the fan-shaped chamber is switched, the denser the recorded time numerical value is, the more accurate the obtained drainage speed is, and the liquid volume threshold value can be adjusted by medical staff according to the condition of the patient.
According to the invention, a manual liquid outlet can be arranged as required, when drainage is finished, the medical staff takes down the drainage device from the drainage catheter to drain accumulated liquid in the drainage catheter, and then the timer 28 is emptied and reset to clean, disinfect and store the device for the next use.
The invention has the following remarkable advantages: firstly, the invention designs three liquid collecting cavities 2 which are uniformly distributed on the circumference, the liquid collecting cavities 2 are descended by the weight of liquid collected in the liquid collecting cavities 2 at the liquid collecting position, then the vertical rod 11 shifts the liquid collecting cavities 2 to rotate to realize the automatic switching of the liquid collecting cavities 2, so that the three liquid collecting cavities 2 automatically and alternately collect and discharge liquid, and the liquid automatically circulates without manual intervention, thereby greatly reducing the workload of medical care personnel and nursing personnel, and avoiding the problem that the stored drainage liquid overflows or flows back to the human body without being poured in time due to the negligence of the medical care personnel or the nursing personnel, and causing iatrogenic pollution; in addition, the invention can also adjust the liquid volume threshold value when the liquid collecting cavity 2 is switched through the screw rod so as to meet the monitoring requirements of different patients; in addition, the invention is additionally provided with a timer 28, the time value of each liquid drainage can be automatically recorded, the drainage speed in the time period can be calculated through the time difference of two adjacent times, the change trend of the drainage speed can be obtained through comparing or drawing the change curve of the drainage speed in a plurality of time periods, and the invention can be used for diagnosing the pathological characteristics of patients or medical data such as rehabilitation condition and the like.
In conclusion, the invention does not need special nursing, greatly reduces the workload of medical care personnel, can avoid iatrogenic pollution caused by the fact that accumulated liquid is not processed in time, and can calculate the drainage speed and the change trend of the drainage speed, so the degree of automation is high, the use is safe and effective, and the functions are comprehensive.
