Embodiment 1

[0026] refer to Figure 1-3 , a pleural effusion suction device for cardiovascular surgery, comprising a mobile seat, a fixed frame, a container barrel 4, an end cover 5, a liquid guiding mechanism and an air bag 18, wherein:

[0027] A plurality of container barrels 4 are placed on the movable seat, the end cover 5 is clamped to the container barrel 4, the fixed frame is fixedly connected to the movable seat, the fixed frame is fixedly connected to the container barrel 4, the fixed frame is fixedly connected to the liquid guide mechanism, and the liquid guide mechanism is connected to the end cover 5, The air bag 18 is connected to the liquid guiding mechanism, and the moving seat drives the container barrel 4 to move. After moving to the corresponding position, the hand presses the air bag 18. After the external force disappears, negative pressure is generated in the liquid guiding mechanism, and the pleural effusion flows from the inlet of the liquid guiding mechanism. The ...

Embodiment 2

[0034] By pressing the airbag 18 to generate negative pressure in the catheter 17, it is necessary to continuously press the airbag 18, and the effusion also passes through the airbag 18 during the liquid suction process. The inlet is sprayed out, causing the effusion in the conduit 17 to flow back, refer to Figure 1-5 , as another preferred embodiment of the present invention, on the basis of Embodiment 1, it also includes a hollow column 19, a power mechanism, a one-way outlet valve 26, a fixed sleeve 27, a one-way inlet valve 28 and a push mechanism, and the hollow column 19 is fixedly connected to the fixed frame, the hollow column 19 is perpendicular to the movable seat, the upper end of the hollow column 19 is connected to the one-way air outlet valve 26, and the push mechanism is slidably connected in the hollow column 19, and the push mechanism is matched with the hollow column 19, and the power mechanism is fixedly connected The moving seat and the push mechanism are...

Embodiment 3

[0040] After the effusion is housed in the container barrel 4, the container barrel 4 needs to be cleaned after the operation. When the container barrel 4 is cleaned, water or effusion will enter the push plate 25 and the one-way air outlet Between the valves 26, adhere to the inner wall of the hollow column 19, thereby affecting the movement of the push plate 25, refer to Figure 1-5 , as another preferred embodiment of the present invention, on the basis of Embodiment 2, it also includes a fixed box 29, an elastic sealing mechanism, a connecting pipe 35, a connecting sleeve 38 and a limit rod 39, and the fixed box 29 communicates with the one-way air intake The valve 28 and the fixed box 29 are used to prevent water or effusion from passing through the one-way inlet valve 28. The upper end of the fixed box 29 is provided with a first air guide hole 34, and one end of the connecting pipe 35 is fixedly connected to the end cap 5, and the connecting pipe 35 The other end passes...

Abstract

The invention relates to the technical field of medical instruments, in particular to a pleural effusion suction device for cardiovascular surgery, which comprises a moving seat, a fixing frame, container barrels, an end cover, a drainage mechanism and an air sac, wherein the multiple container barrels are placed on the moving seat, the end cover is connected with the container barrels in a clamped mode, the fixing frame is fixedly connected with the moving seat, and the fixing frame is fixedly connected with the container barrels. The fixing frame is fixedly connected with the liquid guide mechanism which is communicated with the end cover, and the air bag is communicated with the liquid guide mechanism. The container barrels are driven by the movable seat to move to the corresponding positions, the air bag is pressed by the hand, negative pressure is generated in the drainage mechanism after external force disappears, pleural effusion enters from an inlet of the drainage mechanism and flows into the container barrels, and the extracted effusion is dispersed and contained by the multiple container barrels. The situation that the liquid suction time is prolonged due to the fact that the container barrel is full and replaced is avoided, and wound healing is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pleural effusion suction device for cardiovascular surgery. Background technique [0002] Cardiovascular surgery includes diseases of cardiac surgery and general thoracic surgery. Drainage is often used to deal with pleural effusion and other problems during treatment of this type of disease. Surgical drainage uses a suction device to suck out the pleural effusion and speed up wound healing. In the process of absorbing liquid from the thorax, usually only one liquid storage bottle of the washing device is used to contain the sucked liquid. In order to facilitate the lifting of the suction device, the volume of the liquid storage bottle is generally small, but During the liquid suction process, when there is a lot of liquid, the liquid storage bottle cannot contain all the suctioned liquid, and it is easy to cause backflow when the liquid storage bottle is full, so i...
