Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a medical effusion drainage device. Background Art

[0002] It is common to have fluid accumulation after breast cancer surgery. Treatments include watchful waiting, puncture and fluid extraction, drainage, drug therapy, and surgical repair. You should seek medical attention in time, be evaluated by a professional doctor, and take appropriate treatment measures to prevent possible complications.

[0003] For example, a Chinese utility model patent (CN202554559U) discloses a disposable subcutaneous fluid drainage device, which records: "The advantages of the utility model are that the required items are packaged in the same sterile bag, which is convenient for doctors to operate. The drainage needle is sharp and the catheterization is completed instantly. No anesthesia and suturing are required. The patient's trauma is minimal. The patient and his family can aspirate intermittently at home, and the drainage effect is good without affecting daily activities. In addition, the Y-shaped design of the drainage tube can avoid body fluid contamination caused by the outflow of drainage fluid during catheterization, ensuring the safety of operators and patients", etc., and also records: "However, since some patients still have fluid accumulation after the tube is removed, doctors often need to aspirate with a syringe. Returning to the hospital for aspiration every day or every other day causes a certain economic burden and psychological trauma to the patients. Some out-of-town patients often have long-term incisions due to untimely medical treatment." Technical problems.

[0004] In summary, the device also has the following technical problems: due to the different sizes of the lesions, the amount of fluid accumulated inside is also different. If there is a lot of fluid accumulated inside, repeated suction is required when using the device to drain the fluid. At the same time, since the device requires puncture when draining the fluid, most of the patient's family members are not medical personnel, so there is a high possibility that they will not operate in a standardized manner during the operation, causing the syringe needle to accidentally injure themselves. For this reason, it is necessary to propose a medical fluid drainage device to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content

In addition, the protection of the rubber cover 6 can also prevent infection in the wound of the patient.

[0032] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] Please refer to Figure 2-Figure 5 A medical fluid drainage device comprises a suction shell 1 and a negative pressure suction mechanism 2, wherein the middle of the suction shell 1 is connected with the negative pressure suction mechanism 2 for draining the fluid accumulated in the wound of the patient;

[0035] The negative pressure suction mechanism 2 includes a docking cover 3, a storage tank 4, a conveying component, an air suction component, a negative pressure component, a reset component and an indication component. The bottom surface of the suction shell 1 is fixedly connected to the docking cover 3, and the bottom of the docking cover 3 is threadedly connected to the storage tank 4.

[0036] Specifically, the conveying assembly includes a conveying pipe 5 and a rubber cover 6. The conveying pipe 5 is fixedly connected to the middle of the suction shell 1. The end of the conveying pipe 5 away from the suction shell 1 is inserted into the interior of the storage tank 4 through the docking cover 3. The end of the conveying pipe 5 away from the storage tank 4 is fixedly connected to the rubber cover 6.

[0037] Specifically, the air suction component includes a negative pressure suction pipe 7, a first one-way valve 8, an exhaust pipe 9 and a second one-way valve 10. The middle part of the docking cover 3 is fixedly connected to the middle part of the docking cover 3. The end of the negative pressure suction pipe 7 away from the docking cover 3 is arranged in the middle part of the suction shell 1. One end of the negative pressure suction pipe 7 is fixedly connected to the first one-way valve 8. The surface of the negative pressure suction pipe 7 is fixedly connected to the exhaust pipe 9. The end of the exhaust pipe 9 away from the negative pressure suction pipe 7 passes through the outside of the suction shell 1. The surface of the exhaust pipe 9 is fixedly connected to the second one-way valve 10.

[0038] Specifically, the negative pressure assembly includes a telescopic rod 12, a limit block 13 and a piston 14. The middle part of the suction shell 1 is slidably connected with the telescopic rod 12, one end of the telescopic rod 12 is fixedly connected with the limit block 13, and the end of the telescopic rod 12 away from the limit block 13 is fixedly connected with the piston 14, and the piston 14 is slidably connected to the inner wall of the negative pressure suction tube 7.

[0039] Specifically, the reset assembly includes a fixed disk 15, a spring 16, a guide groove 11, a fixed ring 17 and a handle 18. The surface of the telescopic rod 12 is fixedly connected to the fixed disk 15, the surface of the telescopic rod 12 is sleeved with a spring 16, the two ends of the spring 16 are respectively fixedly connected to the fixed disk 15 and the inner wall of the suction shell 1, the surface of the suction shell 1 is provided with a guide groove 11, the surface of the fixed disk 15 is fixedly connected to the fixed ring 17, the surface of the fixed ring 17 is fixedly connected to the handle 18, and the handle 18 is slidably connected to the surface of the guide groove 11.

[0040] Through the above structural design, when the device is used, the delivery tube 5 is first docked with the drainage tube. After completion, the handle 18 is pulled backward inside the guide groove 11. The handle 18 drives the telescopic rod 12 to move backward through the fixed ring 17 and the fixed plate 15, and then the piston 14 moves backward inside the negative pressure suction tube 7. During the backward movement of the piston 14, the gas inside the storage tank 4 is extracted to form a negative pressure environment inside the storage tank 4. After the negative pressure is generated inside the storage tank 4, the pressure in the patient's body can be extracted through the delivery tube 5. At the same time, the fixed plate 15 cooperates with the inside of the suction shell 1 to squeeze the spring 16. When the handle 18 moves to the rearmost end of the guide groove 11, the elastic potential energy is released by the spring 16 to push the fixed plate 15 and the telescopic rod 12 forward. During the forward movement of the telescopic rod 12, the gas inside the negative pressure suction tube 7 is discharged to the outside through the exhaust pipe 9. Since the first one-way valve 8 and the second one-way valve 10 are provided, when the piston 14 moves backward, the first one-way valve 8 opens and the second one-way valve 10 closes. When the piston 14 moves forward, the second one-way valve 10 opens and the first one-way valve 8 closes. This process is repeated to complete the discharge of the accumulated fluid in the patient's body.

[0041] Embodiment 2:

[0042] The medical effusion drainage device provided in Example 1 is further optimized. Specifically, Figure 3 As shown, the indicating assembly includes a floating plate 19 and scale lines 20 . The surface of the delivery pipe 5 is slidably connected with the floating plate 19 , and the surface of the storage tank 4 is provided with scale lines 20 .

[0043] Through the above-mentioned structural design, when the accumulated fluid in the patient's body is completely extracted, since the density of the float plate 19 is less than the density of the accumulated fluid, the float plate 19 will always be suspended on the upper end of the accumulated fluid. After completion, the storage tank 4 is placed horizontally, and the relative position of the float plate 19 and the scale line 20 is observed to determine the amount of fluid discharged from the patient's body.
