[0002] Malignant pleural effusion is a common complication of advanced tumors. Chemical pleurodesis is still the preferred method for treating malignant pleural effusion at present. Its curative effect depends on sufficient thoracic drainage, complete expansion of the lungs and effective chemical agents. The mechanism is that after the effusion is completely drained, the visceral and parietal pleura are in close contact, and the chemical agent induces a rapid and extensive inflammatory reaction in the thoracic cavity, resulting in pleural fibrosis and adhesion of the visceral and parietal pleura, thereby eliminating the pleural cavity. Although the current chemotherapy drugs have developed rapidly, there is still no ideal effect on the recurrent pleural effusion in many patients. Interventional drug delivery and drainage has the characteristics of minimally invasive and quick recovery.

The lower-end interface of the three-way joint 11 is fixedly connected with a flexible tube 12. The lower end of the flexible tube 12 is fixedly connected with a puncture needle 13.

[0023] In order to facilitate the drainage of the accumulated liquid in the drainage cavity 3, a medicine inlet tube 14 is fixedly connected to the left side of the box body 1 and near the top. The right end of the medicine inlet tube 14 penetrates to the inner cavity of the medicine storage cavity 2. A liquid discharge tube 15 is fixedly connected to the bottom of the right side of the box body 1. The left end of the liquid discharge tube 15 penetrates to the inner cavity of the drainage cavity 3. A butterfly valve 16 is installed on the liquid discharge tube 15.

[0024] In order to facilitate the entry of the medicine liquid into and be discharged into the drainage cavity 3 and prevent the backflow of the accumulated liquid in the drainage cavity 3, a first one-way valve 17 is installed on the medicine delivery tube 9, and a second one-way valve 18 is installed on the drainage tube 10.

[0025] In order to be able to remind medical staff when the liquid medicine in the medicine storage cavity 2 is about to be exhausted, a connection box 19 is fixedly connected to the left side of the top surface of the box body 1. A photoelectric signal receiving end 20 is fixedly connected to the bottom surface of the inner wall of the connection box 19. A first through hole is opened on the left side of the top of the box body 1. A connecting rod 21 is movably connected in the first through hole. The two ends of the connecting rod 21 respectively penetrate to the outside of the top of the box body 1 and the inside of the medicine storage cavity 2. The bottom surface of the connecting rod 21 is fixedly connected to the left side of the top surface of the push plate 5. A connecting block 22 is fixedly connected to the top surface of the connecting rod 21. A push block 23 is fixedly connected to the bottom surface of the connecting block 22. The push block 23 has an open bottom structure. A photoelectric signal transmitting end 24 is fixedly connected to the top surface of the inner wall of the push block 23. The photoelectric signal receiving end 20 and the photoelectric signal transmitting end 24 cooperate with each other. An alarm 25 is fixedly connected to the middle of the top surface of the box body 1. The photoelectric signal receiving end 20 is electrically connected to the alarm 25.

[0026] In order to block the signal emitted by the photoelectric signal transmitting end 24 when the liquid medicine in the medicine storage cavity 2 has not reached the level of being about to be exhausted, so that the signal will not be received by the photoelectric signal receiving end 20, second movable holes are opened on both the left and right sides of the connection box 19. A connecting shaft 26 is movably sleeved in each of the two second movable holes. The two ends of the connecting shaft 26 respectively penetrate to the inner cavity and the outside of the connection box 19. Movable blocks 27 are fixedly connected to the opposite end faces of the two connecting shafts 26. The top surfaces of the two movable blocks 27 are inclined surfaces. Blocks 28 are fixedly connected to the bottom surfaces of the two movable blocks 27. When the opposite faces of the two blocks 28 are in contact with each other, springs 29 are sleeved on the middle parts of the surfaces of the two connecting shafts 26. One end of each spring 29 is fixedly connected to the block 28, and the other end of each spring 29 is fixedly connected to the side surface of the inner wall of the connection box 19.

[0027] In order to prevent the movable block 27 from rotating when moving left and right, thereby avoiding the inclined surface of the movable block 27 being rotated to other orientations, chutes 30 are opened on both the left and right sides of the bottom surface of the connection box 19. A slider 31 is slidably connected in each chute 30. The top surfaces of the two sliders 31 are respectively fixedly connected to the bottom surface of the adjacent movable block 27.

[0028] In order to be able to check the remaining amount of the liquid medicine in the medicine storage cavity 2 at any time, a groove is opened on the left side of the front surface of the box body 1. The groove is communicated with the medicine storage cavity 2. A visible glass plate 32 is fixedly nested in the groove. Scale lines are engraved on the front surface of the visible glass plate 32.

[0029] Working principle: When the utility model is in use, first implant the puncture needle 13 into the human body to the lesion position, then pull the pull ring 8. The pull ring 8 drives the pull rod 6 to rise, the pull rod 6 drives the pull plate 7 to rise, and a negative pressure is generated at the bottom of the inner cavity of the drainage cavity 3 on the pull plate 7. The negative pressure sucks the effusion at the patient's lesion position into the drainage cavity 3 in sequence through the puncture needle 13, the hose 12, the three-way joint 11 and the drainage tube 10. The second one-way valve 18 can prevent the effusion in the drainage cavity 3 from flowing back. Opening the butterfly valve 16 can discharge the effusion in the drainage cavity 3 through the drain pipe 15. Inject the medicinal liquid into the medicine storage cavity 2 through the medicine inlet pipe 14. After the effusion is sucked away, start the cylinder 4. The cylinder 4 pushes the push plate 5 to descend. The push plate 5 descending pushes the medicinal liquid in the medicine storage cavity 2 into the medicine delivery pipe 9, and injects the medicinal liquid into the patient's lesion position in sequence through the three-way joint 11, the hose 12 and the puncture needle 13 to treat the patient. Through the above operations, it is convenient to perform effusion drainage and medicine administration operations on the patient. The operation is convenient and the practicability is high. When the push plate 5 descends, it will drive the connecting rod 21 to descend. The connecting rod 21 drives the connecting block 22 to descend. The connecting block 22 drives the push block 23 to descend. When the push plate 5 descends close to the bottom of the medicine storage cavity 2, the medicinal liquid in the medicine storage cavity 2 is about to be drained out. At this time, the push block 23 also enters the interior from the top of the connection box 19. The bottom surface of the push block 23 contacts the top surface of the movable block 27. As the medicinal liquid in the medicine storage cavity 2 continues to decrease, the push block 23 continues to descend and will push the two movable blocks 27 to move away from each other, making the two stop blocks 28 move towards each other, so that the stop blocks 28 no longer block the photoelectric signal emitted by the photoelectric signal emitting end 24. At this time, the photoelectric signal receiving end 20 can receive the photoelectric signal emitted by the photoelectric signal emitting end 24. After the photoelectric signal receiving end 20 receives the signal, it controls the alarm 25 to start, so that the alarm 25 gives an alarm, reminding the medical staff that the medicinal liquid in the medicine storage cavity 2 is about to be delivered, and the medical staff can perform subsequent operations in time to avoid air entering the patient's body after the medicinal liquid is drained out.

[0030] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0031] The above embodiments only express several implementation manners of the utility model, and the description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
