DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A chest drainage device used in thoracic surgery comprises a drainage bottle 1, a drainage tube 2 and a fixed needle 3. A cleaning tube 4 is fixedly connected to the side wall of the drainage tube 2 on one side of the fixed needle 3, and the cleaning tube 4 is communicated with the drainage tube 2. A valve 5 is fixedly connected to the other end of the cleaning tube 4, and a connector 6 is fixedly connected to the other end of the valve 5, and the connector 6 is communicated with the valve 5. A cleaning needle 7 is provided on one side of the connector 6, and the needle head of the cleaning needle 7 is slidably connected to the inner wall of the connector 6. A blocking device is provided on one side of the cleaning tube 4 and the fixed needle 3.

[0023] It can be seen from the above structure that by setting the drainage bottle 1, drainage tube 2, fixed needle 3, cleaning tube 4, valve 5, connector 6, cleaning needle 7 and blocking device for use together, when the drainage tube 2 is blocked, the needle of the cleaning needle 7 is connected to the connector 6, and then the valve 5 is opened and the cleaning needle 7 is used to inject a dissolving solution into the drainage tube 2 through the connector 6, valve 5 and cleaning tube 4 to dissolve the blocked blood clots and pus, and then suction is performed to clean the blockage to ensure the smooth flow of the drainage tube 2. At the same time, the blocking device is activated to block the end close to the fixed needle 3 to prevent the cleaning needle 7 from affecting the patient when sucking out the blockage in the drainage tube 2. Then the valve 5 is closed and the blocking device is opened, so that the drainage tube 2 can continue to smoothly complete the patient's drainage work. The operation is simple and convenient, and the drainage efficiency is improved.

[0024] Furthermore, the blocking device includes a blocking block 8 slidably connected to the side wall of the drainage tube 2, and a sliding cavity 9 is opened inside the blocking block 8, and a pressing block 10 is slidably connected to the inner wall of the sliding cavity 9, and the bottom surface of the pressing block 10 is against the side wall of the drainage tube 2, and the upper surface of the pressing block 10 is rotatably connected to the adjusting screw 11, and the other end of the adjusting screw 11 passes through the side wall of the sliding cavity 9 and is threadedly connected to the sliding cavity 9; by setting the blocking block 8, the sliding cavity 9, the pressing block 10 and the adjusting screw 11 for use together, before opening the valve 5, the adjusting screw 11 is rotated to drive the adjusting screw 11 to move downward along the sliding cavity 9, and then the adjusting screw 11 is adjusted. The pressing block 10 rotatably connected at one end will slide downward along the sliding cavity 9, and the downwardly moving pressing block 10 will squeeze the side wall of the drainage tube 2 in the sliding cavity 9, so that the inner wall of the drainage tube 2 is in harmony, thereby completing the blocking work of the drainage tube 2, so that when the cleaning needle 7 draws out the drainage tube 2, it will not affect the patient, thereby improving the safety when using the cleaning needle 7, and at the same time, it can push the blocking block 8 to drive the pressing block 10 to slide along the side wall of the drainage tube 2, and push the blood clots and pus in the drainage tube 2 between the cleaning tube 4 and the fixed needle 3 to one side of the cleaning tube 4, so that the dissolving liquid injected into the drainage tube 2 is convenient for dissolution, thereby improving the cleaning efficiency.

[0025] Furthermore, one end of the adjusting screw 11 located outside the blocking block 8 is fixedly connected with an anti-skid adjusting cap 12; by providing the anti-skid adjusting cap 12, the anti-skid adjusting cap 12 can be rotated to drive the adjusting screw 11 to rotate, which is convenient for medical personnel to operate.

[0026] Furthermore, a pressing roller 13 is hinged on the bottom surface of the pressing block 10; by setting the pressing roller 13, when the blocking block 8 drives the pressing block 10 to slide along the drainage tube 2, the pressing roller 13 will roll along the side wall of the drainage tube 2, making it convenient for the blocking block 8 to drive the pressing block 10 to slide along the drainage tube 2, thereby preventing the pressing block 10 from scratching the drainage tube 2 and causing unnecessary damage.

[0027] Furthermore, the pressing roller 13 is made of plastic material; by providing a plastic material, the pressing roller 13 made of plastic material is relative to the hard pressing roller 13. The hard pressing roller 13 has a higher hardness of its material. When it contacts the drainage tube 2 during the rolling process, it may generate greater pressure and friction on the surface of the drainage tube 2, especially when encountering tiny protrusions or unevenness on the surface of the drainage tube 2, it is more likely to cause scratches. The pressing roller 13 made of plastic material is relatively soft and has a certain elasticity. When it contacts the drainage tube 2, it can better adapt to the shape of the surface of the drainage tube 2, reducing the direct pressure and friction on the surface of the drainage tube 2, thereby reducing the risk of scratching the drainage tube 2 and improving the safety of the blocking block 8 driving the pressing block 10 to slide along the drainage tube 2.

[0028] Furthermore, a limiting groove 14 is provided on the side wall of the blocking block 8; by providing the limiting groove 14, when the drainage tube 2 performs drainage work, the limiting groove 14 can be slidably connected to the side wall of the cleaning tube 4, thereby preventing the blocking block 8 from rotating freely along the drainage tube 2, causing the drainage tube 2 to shake, and then causing the fixed needle 3 to shake, affecting the patient, and then affecting the safety of the use of the blocking device.
