[0027] AsFigures 1-7 As shown, a safe and adjustable miniature negative pressure drainage device for post-mastectonic surgery includes a housing 1. Inside the housing 1, a negative pressure mechanism 5 for controlling negative pressure and a negative pressure box 6 for storage are respectively provided. A drainage mechanism 3 is provided at one end of the negative pressure box 6. A controller 2 is provided on the outside of the housing 1. In this embodiment, the controller 2 is provided with a screen and buttons on the outside, so as to display and manually operate the negative pressure mechanism 5. A pressure sensor is provided inside the controller 2 to measure pressure and can automatically adjust according to the pressure inside the negative pressure box 6. The pressure inside the negative pressure box 6 can be adjusted by the negative pressure mechanism 5 to adapt to wounds of different sizes. When drainage is required, the drainage mechanism 3 is first inserted into the area to be drained, and then the negative pressure mechanism 5 controls the negative pressure box 6 to generate negative pressure for drainage. When carrying, the housing 1 can be placed directly in a pocket for easy carrying.

[0028] like Figures 1-7 As shown, the drainage mechanism 3 includes a drainage tube 303, which is connected to the negative pressure box 6. One end of the drainage tube 303 is fixedly connected to a fixing plate 301, and one side of the fixing plate 301 is fixedly connected to an adhesive tape 302. In this embodiment, a needle is fixedly connected to one side of the fixing plate 301. In this embodiment, when drainage is required, the needle is first inserted into the area where drainage is needed. After insertion, the fixing plate 301 is made to fit tightly against the skin, thereby making the needle more stable. Then, the adhesive tape 302 is stuck to the skin to further fix the fixing plate 301 and prevent the needle from falling off.

[0029] like Figures 1-7As shown, the negative pressure mechanism 5 includes a fixed ring 503, the bottom of which is connected to the inner wall of one end of the shell 1, and a gas bag 504 is fixedly connected inside the fixed ring 503, exhaust holes 511 are formed at the top edge of the gas bag 504, an air inlet hole 512 is formed on one side of the gas bag 504, a connecting pipe 502 is fixedly connected to the outside of the air inlet hole 512, a one-way valve 501 is fixedly connected to one end of the connecting pipe 502, and the one-way valve 501 is in communication with the negative pressure box 6, a gas outlet cover 505 is fixedly connected to the top center of the gas bag 504, an extension column 506 is fixedly connected to the top of the gas outlet cover 505, a limiting groove 514 is formed on the outside of the extension column 506, a limiting column 513 is slidably connected inside the limiting groove 514, and the limiting column 513 is connected to the motor 508, a sliding column 510 is fixedly connected inside the extension column 506, a rotating column 507 is rotatably connected inside the extension column 506, an annular inclined groove 509 is formed on the outside of the rotating column 507, and the sliding column 510 slides inside the annular inclined groove 509, one end of the rotating column 507 is rotatably connected to the motor 508, and the motor 508 is connected to the shell 1. In this embodiment, the gas bag 504 and the gas outlet cover 505 are both made of rubber. When drainage is needed, the motor 508 is first rotated, and the motor 508 drives the rotating column 507 to rotate through the output shaft. Because the annular inclined groove 509 is formed on the outside of the rotating column 507, and the limiting column 513 fixed to the outside of the motor 508 and the limiting groove 514 formed on the outside of the extension column 506 are used to limit the extension column 506, the extension column 506 is ensured to move linearly, so that the annular inclined groove 509 drives the sliding column 510 inside the extension column 506 to slide inside the annular inclined groove 509 while rotating, and the extension column 506 moves linearly and reciprocally, and the gas bag 504 is compressed and reset at the same time. Before the gas bag 504 is compressed, the gas inside the gas bag 504 flows out by pushing away the gas outlet cover 505 through the exhaust holes 511. When the gas bag 504 is reset, the gas outlet cover 505 tightly abuts against the surface of the gas bag 504 to block the exhaust holes 511, and the one-way valve 501 is opened to allow the gas in the negative pressure box 6 to be drawn out through the connecting pipe 502. When the gas bag 504 is compressed again, the one-way valve 501 is closed to form negative pressure inside the negative pressure box 6 to attract the part that needs to be drained.

[0030] As shown in Figures 1-7 the other end of the shell 1 is slidably connected to a sliding mechanism 4, the sliding mechanism 4 includes a sliding plate 401 that slides inside the other end of the shell 1, sliding strips 403 are fixedly connected to the two sides of the sliding plate 401, and a spring 402 is fixedly connected to one end of the sliding plate 401. In this embodiment, the spring 402 of the sliding plate 401 is used to fix the negative pressure box 6 to prevent the negative pressure box 6 from moving to generate gaps during use, which would result in the inability to drain.

[0031] As shown in Figures 1-7As shown, the left and right inner walls of the shell 1 are fixedly connected with fixed strips 101, the fixed strips 101 are slidably connected with connecting strips 7, the connecting strips 7 are connected with the negative pressure boxes 6, the upper and lower inner walls of the shell 1 are fixedly connected with sliding grooves 102, and the sliding grooves 102 are matched with the sliding strips 403. In this embodiment, the fixed strips 101, the connecting strips 7 and the sliding grooves 102 and the sliding strips 403 are arranged, so that the negative pressure boxes 6 and the sliding plate 401 can be quickly installed.

[0032] As shown, Figures 1-7 The shell 1 is made of plastic material. In this embodiment, the use of the plastic material reduces the overall weight, thereby facilitating carrying.
