According to fig. 1 and fig. 2, the present embodiment provides a pericardial effusion drainage and extraction device, which includes a liquid collection cup 1 for collecting pericardial effusion. The bottom of the liquid collecting cup 1 is made of elastic material. The bottom of the liquid collecting cup 1 is provided with a liquid inlet 2 for inserting a conduit 4, and the bottom of the liquid collecting cup 1 is provided with a sealing cover 3. The diameters of the sealing cover 3 and the conduit 4 are both larger than or equal to the diameter of the liquid inlet 2. The sealing cover 3 covers the liquid inlet 2, so that the sealing cover 3 can seal the liquid inlet 2 when the liquid collecting cup 1 is replaced or placed. And the sealing cover 3 can be disassembled and assembled. The bottom of the sealing cover 3 is provided with a circular ring protruding outside the liquid collecting cup along the circumferential direction of the sealing cover and a circular ring inner wall provided with threads, and the threads arranged on the sealing cover 3 are matched with the outside of one end of the guide pipe 4 correspondingly to form threads so that the sealing cover 3 is connected with the guide pipe 4 in a thread matching manner. The conduit 4 may seal the loading port 2 during drawing. When the liquid collecting cup is used, the guide pipe 4 is connected with the sealing cover 3 through threads, the guide pipe 4 is pushed into the liquid collecting cup 1, and the sealing cover 3 is pushed into the liquid collecting cup 1 through the guide pipe 4. Because the diameter of pipe 4 is more than or equal to the diameter of inlet 2 simultaneously because the liquid collecting cup 1 bottom is elastic material, so thereby inlet 2 can hug closely pipe 4 well and reach sealed effect. When the conduit 4 needs to be taken out, the conduit 4 is directly pulled out until the sealing cover 3 is positioned at the liquid inlet 2, and the sealing cover 3 can be tightly held by the liquid inlet 2 because the diameter of the sealing cover 3 is larger than or equal to that of the liquid inlet 2. The tube 4 can then be removed by rotating the tube 4 to disengage it from the closure 3. And the sealing cap 3 also seals the inlet 2 at the same time. Therefore, the liquid inlet 2 of the catheter 4 is closed when the catheter is used, and no liquid leakage occurs. The top of the liquid collecting cup 1 is provided with a liquid pumping device 5 for pumping pericardial effusion.

In this embodiment, the upper and lower end portions of the sealing cover 3 are provided with annular protrusions 31 along the circumferential direction, and the annular protrusions 31 are matched with the bottom of the liquid collecting cup 1, so that the sealing cover 3 is fixed to the sealing cover 3 when the liquid inlet 2 is sealed by the sealing cover 3. The sealing cover 3 cannot fall off to cause infirm sealing when sealing is carried out, and the annular bulge 31 can limit the sealing cover 3 when the guide pipe 4 is pulled out, so that the sealing cover cannot be easily pulled out of the liquid collecting cup 1 along with the guide pipe 4.

In this embodiment, the liquid inlet 2 is provided with a limiting opening 21 along the circumferential direction thereof. The sealing cover 3 is provided with a limiting member 32 in cooperation with the limiting port 21, so that the sealing cover 3 is fixed on the liquid inlet 2 when the limiting member 32 is in cooperation with the limiting port 21. Since the pipe 4 needs to be rotated when the pipe 4 needs to be detached from the sealing cover 3, it is easy to bring the sealing cover 3 to rotate together. Therefore, the limit opening 21 and the limit piece 32 are arranged to limit the sealing cover 3, so that the sealing cover and the guide pipe 4 cannot rotate together, and the guide pipe 4 can be conveniently separated from the sealing cover 3.

In this embodiment, the distance between the upper and lower annular protrusions 31 of the sealing cover 3 is smaller than the thickness of the bottom of the liquid collecting cup 1. When the limiting opening 21 is matched with the limiting part 32, the limiting part 32 is required to be aligned with the limiting opening 21 to be matched with the sealing cover 3 to limit the sealing cover. If the distance between the upper part and the lower part of the sealing cover 3 is larger than or equal to the thickness of the bottom of the liquid collecting cup 1, external force needs to be applied to pull the guide pipe 4 outwards, and meanwhile, the guide pipe 4 is rotated to drive the sealing cover 3 to enable the limiting rod to be in butt joint with the limiting port 21. If the distance between the upper portion and the lower portion of the sealing cover 3 is smaller than the thickness of the bottom of the liquid collecting cup 1, when the limiting part 32 is located in the limiting opening 21, the limiting opening 21 can tightly hold the limiting part 32 to limit the liquid collecting cup, and external force does not need to be applied to the limiting part because the bottom of the liquid collecting cup 1 is made of elastic materials.

In this embodiment, a plurality of liquid outlets are formed at one end of the conduit 4 connected to the sealing cover 3 along the circumferential direction. When the conduit 4 is inserted into the liquid collecting cup 1, the end part of the conduit 4 is connected with the sealing cover 3 through the thread and liquid can not be discharged, so that the liquid outlet is arranged at the periphery of the end part, and the flow is increased to discharge pericardial effusion in the conduit 4 more quickly.

In this embodiment, the catheter 4 is provided with a flow regulator 6 that controls the drainage extraction rate. If the flow rate is too high and the suction force is too large, internal bleeding is easily caused, so the flow regulator 6 can be arranged to regulate the flow to avoid the situation. Meanwhile, the catheter can be switched on and off, and when the liquid collecting cup 1 is replaced, leakage of the catheter or the discharge of pericardial effusion can not occur to pollute the external environment.

In this embodiment, the pumping device 5 comprises a pumping barrel 51. The configuration of the barrel 51 is a syringe configuration. The liquid suction tube 51 and the liquid collection cup 1 are connected by a first check valve 52, and the first check valve 52 allows air to flow into the liquid suction tube 51. A second check valve 53 is provided on the side of the liquid suction cylinder 51, and the second check valve 53 is vented to the outside of the liquid suction cylinder 51. The drainage extraction is carried out in one-way ventilation, and the pericardial effusion which is extracted is prevented from being sent back again. Meanwhile, the liquid pumping cylinder 51 adopts a syringe structure, so that the pumping speed can be manually adjusted at any time according to the situation.

In this embodiment, the liquid collecting cup 1 is a transparent cup and the surface thereof is provided with a graduated scale. The amount of the extracted liquid can be conveniently observed, and further treatment can be carried out according to the amount of the extracted liquid.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
