[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0039] The embodiments of the present invention will be described below according to its overall structure.

[0040] A pleural effusion drainage device and its usage method, as Figures 1-7 shown, includes a guide rod 1, on which a pressure regulating device is slidably arranged. When pleural effusion is extracted through the pressure regulating device, the pressure is regulated by the pressure regulating device to ensure the comfort of the patient during the extraction of pleural effusion. One side of the pressure regulating device is connected to an infusion tube 8, and the other end of the infusion tube 8 is connected to a puncture device. The puncture device punctures at a specified position of the patient. At this time, the puncture operation is performed through the puncture device, and then the pleural effusion is extracted;

[0041] The puncture device includes a rubber sleeve 13, and the puncture device also includes a ring 3, which is arranged on the top of the rubber sleeve 13, and a cover 4 is arranged on the top of the ring 3. A puncture needle 6 is penetrated on the fixed plate 20, and a needle 7 is arranged at the bottom of the puncture needle 6. The needle 7 is convenient for inserting the puncture needle into the patient's body. A central spacer 21 is arranged in the rubber sleeve 13 to cooperate with the catheter 33. In actual use, the puncture needle 6 is inserted into the affected part of the patient by aligning it with the patient, and the top of the cover 4 is matched with the puncture needle 6. A rotating member 5 is arranged, and the rotating member 5 is matched with the puncture needle 6. It cooperates with the external thread of the puncture needle 6, so that the position of the puncture needle 6 can be adjusted by rotating the rotating member 5, so as to adjust the needle position according to the patient's condition. At the same time, a catheter 33 is movably provided on one side of the puncture needle 6, and the catheter 33 is connected to the puncture needle 6 by a connecting ring 32. The infusion tube 8 passes through the puncture needle 6 and extends from the catheter 33. After the puncture needle is inserted into the patient's body, the medical staff controls the catheter 33 to adjust it. After the puncture needle 6 is inserted into the patient's body, the position of the pleural effusion is adjusted in detail by adjusting the control catheter 33.

[0042] On the basis of the above structure, a diaphragm 19 is provided at the bottom of the rubber sleeve 13, a fixing plate 20 is provided at the center of the diaphragm 19, a plurality of metal patches 2 are provided at the bottom of the fixing plate 20, and a thermal conductive patch 17 is provided at the top of the diaphragm 19. Through such a setting, in actual use, the rubber sleeve 13 is filled with cooling liquid. In actual use, the cooling liquid contacts the thermal conductive patch 17, and the surface temperature of the metal patch 2 on the other side of the thermal conductive patch 17 is reduced. When performing the puncture operation, the cold metal patch 2 contacts the patient's skin at the puncture position, thereby achieving an analgesic effect. At the same time, a rubber ring 18 is provided in a circle inside the rubber sleeve 13, and the rubber ring 18 supports the entire inner wall of the rubber sleeve 13.

[0043] In the above structure, the rubber sleeve 13 and the diaphragm 10 are both flexible. In actual use, it is ensured that the entire rubber sleeve 13 can fit the patient's skin relatively well, and it is ensured that in the above structure, the metal patch 2 can fit the patient's skin relatively well.

[0044] Further, the pressure regulating device includes a sliding block 9, a sliding groove 10 is provided on the guide rod 1 to cooperate with the sliding block 9, a mounting groove 27 is provided on one side of the sliding block 9, a connecting plate 23 is provided in the mounting groove 27, a liquid storage bag 28 is provided at the bottom of the connecting plate 23, a second connecting port 26 is provided at the top of the liquid storage bag 28, a first connecting port 25 is provided on the sliding block 9 to cooperate with the second connecting port 26, a sliding plate 11 is provided at the bottom of the guide rod 1 to cooperate with the sliding plate 11 to slide, a supporting spring 31 is provided on the top of the sliding plate 11, and the supporting spring 31 is connected to the sliding block 9, a mounting top plate 30 is provided at the top of the guide rod 1, a pull ring 29 is provided at the bottom of the mounting top plate 30, a pull ring 29 is provided on the sliding block 9, and an elastic band 22 is connected between the pair of pull rings 29. In actual use, after the puncture needle 6 is inserted into the patient's body, the initial position of the pressure regulating device is adjusted to control the extraction speed of the pleural effusion;

[0045] Specifically, after the puncture needle 6 enters the body, the pleural effusion is discharged from the catheter 33 and enters the liquid storage bag 28. The weight of the liquid storage bag 28 increases accordingly, which causes the sliding block 9 to move downward. At this time, the cooperation of the elastic band 22 and the spring 31 provides a critical weight for the collection of pleural effusion. The position of the sliding block 9 will stop at the critical position, thereby stopping the collection of the pleural effusion. Among them, the sliding block 9 and the liquid storage bag 28 are located at a higher position, and the liquid is initially drawn slowly to reduce the stimulation of the liquid drawing to the patient. As the liquid is drawn, the mass of the liquid in the liquid storage bag 28 increases, thereby driving the sliding block 9 to descend. At this time, the descending rate of the sliding block 9 is guaranteed by the spring 31, thereby ensuring the stability of excessive extraction. After a certain amount of pleural effusion is extracted, the sliding block 9 stops moving and the liquid is stopped under the dual action of the elastic band 22 and the spring 31, thereby preventing the patient from feeling uncomfortable due to a large amount of liquid aspirated at a single time.

[0046] The installation groove 27 is provided with a clamping groove 16 to cooperate with the connecting plate 23, and the connecting plate 23 and the liquid storage bag 28 can be quickly taken out through the clamping groove 16 to complete the collection.

[0047] A rotating handle 12 is provided on one side of the sliding plate 11 , and the rotating handle 12 extends into the sliding plate 11 to connect with the fixing plate 24 . By rotating the rotating handle 12 , the position of one end thereof is controlled, so that the fixing plate 24 contacts the guide rod 1 , thereby fixing the sliding plate 11 .

[0048] A support plate 14 is disposed at the bottom of the guide rod 1 , and a plurality of universal wheels 15 are disposed at the bottom of the support plate 14 . The universal wheels 15 enable the entire device to adjust its position according to the user's use requirements.

[0049] Although embodiments of the present invention have been shown and described, the specific embodiments are merely explanations of the present invention and are not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
