According to the drainage device based on the technical characteristics, the liquid inlet cavity 6 is formed between the separator 5 and the inner wall of the tank body by arranging the separator 5 in the tank body, and the liquid inlet cavity 6 is communicated with the liquid inlet; meanwhile, the liquid storage cavity 7 is arranged in the separation body 5, the liquid inlet cavity 6 is communicated with the liquid storage cavity 7, the outer wall of the tank body is connected with the negative pressure pump 16, negative pressure is pumped to the liquid storage tank 3 through the negative pressure pump 16 when drainage is needed, liquid in a patient enters the liquid storage tank 3 through the liquid inlet under the action of the drainage tube 1, the upper end of the separation body is sealed and opposite to the liquid inlet, the liquid entering the tank body through the liquid inlet flows to the upper end of the separation body 5 firstly, then flows into the liquid inlet cavity 6 along with the upper end of the separation body 5, flows to the liquid storage cavity 7 from the liquid inlet cavity 6, and the liquid is isolated from the liquid inlet under the action of the separation body 5, so that backflow of the liquid is avoided. Simultaneously, the one-way valve 4 is arranged at the liquid inlet, so that the backflow of liquid is further avoided under the action of the one-way valve 4, the secondary injury to a patient is avoided, and the treatment effect is ensured.
The two backflow prevention modes can be independently implemented to achieve a good backflow prevention effect, and meanwhile, the optimal technical effect is achieved.
Referring to fig. 2, in this embodiment, with the above arrangement, the liquid needs to flow to the upper end of the separator 5, and then flows into the liquid inlet chamber 6 along with the upper end of the separator 5, so as to ensure that the liquid can flow from the separator 5 to the liquid inlet chamber 6 quickly, the separator 5 includes a main body portion 8 and a guiding portion 9 disposed at the upper end of the main body portion 8, the guiding portion 9 is opposite to the liquid inlet, the guiding portion 9 is conical, the cone top of the guiding portion is opposite to the liquid inlet, and the cone angle is 90-120 degrees, such as 100 degrees, 110 degrees, and the like. A gap is formed between the flow guiding part 9 and the inner wall of the upper end of the tank body. As to how to ensure that liquid can flow from the inlet chamber 6 to the reservoir chamber 7, there are a number of different arrangements, for example:
the main body part 8 is provided with a plurality of liquid inlet holes, and liquid flows from the liquid inlet holes to the liquid storage cavity 7;
for example, a plurality of liquid inlets are uniformly distributed on the main body 8 along the circumferential direction thereof, the liquid inlets extend to the end surface of one end of the main body 8 far away from the flow guiding part 9, and the liquid flows from the liquid inlets to the liquid storage cavity 7;
and if a gap is arranged between the end face of the bottom end of the separator 5 and the bottom surface of the tank body, the liquid flows from the gap to the liquid storage cavity 7. The gap may be formed by providing a support post between the opening and the bottom surface of the can.
In addition, since the liquid flows from the liquid inlet chamber 6 to the liquid storage chamber 7, and the liquid in the liquid inlet chamber 6 flows in from the liquid inlet port, if the space of the liquid inlet chamber 6 is insufficient, the liquid may accumulate in the liquid inlet chamber 6 due to the fact that the speed of the liquid flowing into the liquid storage chamber 7 is slower than the speed of the liquid entering the liquid inlet chamber 6, and drainage is affected; however, if the liquid inlet chamber 6 is too large, the area of the flow guiding portion 9 is small, which affects the effect of isolating the communication between the liquid and the liquid inlet, so the size of the liquid inlet chamber 6 is critical.
In this embodiment, the size of the liquid inlet chamber 6 is defined by the width of the liquid inlet chamber. If the outer diameter of the main body 8 is D 2 The inner diameter of the part of the tank body parallel to the main body part 8 (i.e. the part forming the liquid inlet cavity 6) is D 1 The width of the liquid inlet chamber 6 is W, and w= (D) 1 -D 2 ) And/2, wherein.
；
d is the inner diameter of the drainage tube 1, L is the length of the drainage tube 1, and h is the height of the main body part 8;
ΔP=P-P 1 ，P 1 for the pressure in the liquid storage tank, a vacuum pressure gauge 10 and a vacuum pressure gauge P for detecting the pressure in the tank are arranged on the tank body 1 Measured directly by the vacuum gauge 10. P is the atmospheric pressure.
Since the drainage tube 1 is drained by negative pressure, the flow rate is determined by the pressure difference at the two ends of the drainage tube, and in the case of fixed drainage tube, the flow rate of the liquid is also determined. The liquid inlet cavity 6 is formed by the above mode, the optimal width of the liquid inlet cavity 6 can be obtained by well combining the flow speed of the drainage tube 1, the drainage can be orderly carried out, the area of the flow guiding part 9 is maximally ensured to be in the maximum state, and the backflow preventing effect is ensured.
Referring to fig. 3, in this embodiment, an anti-blocking device 11 is disposed on the drainage tube 1; because blood clots may exist in the drained liquid, the drainage tube 1 is easy to be blocked, and the current medical staff can only solve the problem by replacing the drainage device. According to the application, by arranging the anti-blocking device 11, the blocking of the drainage tube 1 can be effectively avoided, and the normal operation of drainage is ensured.
Specifically, the anti-blocking device 11 comprises a shell 12, two ends of the shell 12 are respectively provided with an inlet and an outlet which are connected with the drainage tube 1, the inlet and the outlet are communicated, at least one hob 13 is arranged in the shell 12, a rotating rod 14 is connected to the hob 13, and the free end of the rotating rod 14 penetrates through the outer wall of the shell 12 for operation. When the blockage occurs, the smoothness of the drainage tube 1 can be ensured only by rotating the rotating rod 14 to crush blood clots. Preferably, the number of the hob is two, and the hob is arranged oppositely, so that larger blood clots can be effectively crushed.
In this embodiment, in order to avoid the blood clot after smashing to stop up again in subsequent process drainage tube 1, the inside of casing 12 is equipped with the lid and establishes filter screen 15 on the export, through setting up filter screen 15, can effectively guarantee the size of blood clot, avoid great blood clot to stop up again drainage tube 1.
However, after the filter screen 15 is disposed, more blood clots may be accumulated on the filter screen 15, so that the liquid cannot pass through the outlet, and in order to solve the above problem, in this embodiment, the drainage device further includes a dredging pipe 23, two ends of the dredging pipe 23 are respectively connected to the housing 12 and the anti-blocking tank 24, and the anti-blocking tank 24 is connected to the negative pressure pump 16. The negative pressure pump 16, the liquid storage tank 3 and the anti-blocking tank 24 can be connected through a three-way valve.
Meanwhile, the drainage tube 1 comprises a first drainage tube 17 connected with the drainage head 2 and the anti-blocking device 11, and a second drainage tube 18 connected with the anti-blocking device 11 and the liquid storage tank 3, valves 25 are arranged on the first drainage tube 17 and the second drainage tube 18, when more broken blood clots are gathered on the filter screen 15, the two valves 25 are closed, then the negative pressure pump 16 is started to pump negative pressure, under the action of pressure difference, liquid in the second drainage tube 18 flows backwards, the filter screen 15 is reversely flushed, the blood clots are separated from the filter screen 15, and the flushed blood clots enter the anti-blocking tank 24 along with the liquid. After washing the filter screen 15 for a period of time, the valve 25 on the first drainage tube 17 can be opened to allow more liquid to enter the housing 12, so that the broken blood clots separated from the filter screen 15 can be conveniently completely carried into the anti-blocking tank 24. When the filter screen 15 is washed clean, or after all the liquid in the second drainage tube 18 flows to the anti-blocking tank 24, the valve 25 on the second drainage tube 18 is opened, meanwhile, the pipeline of the dredging tube 23 is closed, and the drainage device operates normally.
It should be noted that, after the filter 15 has accumulated more blood clots to block the outlet, the liquid in the second drainage tube 18 cannot flow to the liquid storage tank 3 under the action of the negative pressure, but remains in the second drainage tube 18. Meanwhile, since the residual liquid in the second drainage tube 18 is required to flush the filter screen 15, the amount of the liquid in the second drainage tube 18 needs to be ensured as much as possible, and the amount of the liquid in the second drainage tube 18 is determined by the length thereof, so that the space between the valve 25 on the second drainage tube 18 and the liquid storage tank 3 should be as small as possible.
