Description

Technical Field

[0001] This invention relates to the field of negative pressure drainage technology, specifically a continuous negative pressure drainage device for traumatic wounds. Background Technology

[0002] Negative pressure wound therapy is a medical technique that uses negative pressure to remove necrotic tissue from wounds and promote healing. Its mechanisms of action include reducing the number of bacteria, promoting angiogenesis, and improving the fluid balance of the wound.

[0003] During negative pressure drainage, medical waste fluid is usually collected through a collection bottle. However, when the liquid in the collection bottle reaches its maximum capacity, it needs to be replaced. During this replacement, the drainage tube needs to be removed and reconnected. However, the drainage tube has a certain length, and the waste fluid remaining in the tube can easily drip during the insertion and removal process, thus posing a risk of contamination.

At the same time, the elastic sealing pipe 303 ensures liquid flow when there is negative pressure suction and discharge, and prevents liquid from easily flowing out when there is no negative pressure suction and discharge by the compression of the hollow contraction bladder 306.

[0032] The waste liquid collection mechanism includes a waste liquid storage bottle 401, a liquid guide cap 402, a connecting sleeve 403, a rubber sealing gasket 404, a negative pressure extension tube 405, and a negative pressure connector 406. The waste liquid storage bottle 401 is located inside the limiting port 107. When the waste liquid storage bottle 401 is installed, its surface slides against the inner wall of the limiting port 107, and the surface of the waste liquid storage bottle 401 is provided with graduations. The liquid guide cap 402 is located on top of the waste liquid storage bottle 401, and its interior is provided with internal threads, while the surface of the waste liquid storage bottle 401 is provided with external threads. When the waste liquid storage bottle 401 is connected to the liquid guide cap 402, the waste liquid is collected... The bottle 401 is threadedly connected to the liquid guide bottle cap 402 via external and internal threads. The docking sleeve 403 is integrally set on the top of the liquid guide bottle cap 402 and is threadedly connected to the drain plug 313. The rubber sealing gasket 404 is fixedly connected to the inner wall of the liquid guide bottle cap 402. The negative pressure extension tube 405 is fixedly inserted into the top of the liquid guide bottle cap 402. The negative pressure connector 406 is fixedly connected to the top of the negative pressure extension tube 405. With the waste liquid storage bottle 401, liquid guide bottle cap 402, docking sleeve 403, rubber sealing gasket 404, negative pressure extension tube 405 and negative pressure connector 406, the waste liquid storage bottle 401 can be used to ensure the storage of waste liquid during use.

[0033] Working principle: When replacing the waste liquid storage bottle 401, first turn off the suction negative pressure and disconnect the negative pressure pipeline connected to the negative pressure connector 406. Then turn the adjusting handwheel 105. The adjusting handwheel 105 drives the threaded lifting column 104 to rotate. When the threaded lifting column 104 rotates, it pushes the lifting threaded cylinder 108 so that the limiting lifting platform 106 descends along the upper extension guide column 103, thereby causing the limiting port 107 to descend, making it easier for the waste liquid storage bottle 401 to be removed. Then, the pumping motor 209 is started. The pumping motor 209 drives the pumping threaded column 210 to rotate. When the pumping threaded column 210 rotates, it pushes the lifting inner cylinder 213 to rise, so that the lifting top cylinder 211 slides up along the guide groove 208, thereby causing the extension bar 204 to move away from the extension insert 202, so that the pumping corrugated bottle 301 unfolds. When the pumping corrugated bottle 301 unfolds, the internal space increases and a negative pressure is generated, thereby sucking the residual liquid inside the connecting transfer tube 302 and the drainage pipe connected to the liquid inlet insert 311 into the pumping corrugated bottle 301. When the liquid is sucked in, it will expand the elastic sealing tube 303, causing the elastic sealing tube 303 and the hollow shrinking liquid bladder 306 to expand. After the suction is completed, the hollow shrinking liquid bladder 306 squeezes and seals the elastic sealing tube 303 through its own elastic contraction, thereby preventing the liquid inside the pumping corrugated bottle 301 from easily flowing out. Then twist the drain plug 313 to separate it from the docking sleeve 403, then take out the full waste liquid storage bottle 401, place the empty waste liquid storage bottle 401 inside the original limiting port 107, then connect the drain plug 313 to the docking sleeve 403 of the empty bottle liquid drawing corrugated bottle 301, and connect the negative pressure docking connector 406 of the empty bottle liquid drawing corrugated bottle 301 to the negative pressure pipeline. Then, the pumping motor 209 is started. The pumping motor 209 drives the pumping threaded column 210 to rotate in the opposite direction. When the pumping threaded column 210 rotates, it pushes the lifting inner cylinder 213 down, so that the lifting top cylinder 211 slides down along the guide groove 208, and then the extension bar 204 approaches the extension insert 202, so that the pumping corrugated bottle 301 contracts. The residual liquid is discharged from the inside of the pumping corrugated bottle 301 into the docking transfer pipe 302, and finally into the waste liquid storage bottle 401. When the liquid is discharged, it will expand the elastic sealing tube 303, so that the elastic sealing tube 303 and the hollow shrinking liquid bladder 306 expand. After the liquid is discharged, the hollow shrinking liquid bladder 306 contracts through its own elasticity. At the same time, the check duckbill valve 305 is closed during the liquid discharge, thereby preventing the residual liquid from flowing back to the wound along the drainage pipe. Then, the adjusting handwheel 105 is turned in the opposite direction. The adjusting handwheel 105 drives the threaded lifting column 104 to rotate in the opposite direction. When the threaded lifting column 104 rotates, it pushes the lifting threaded cylinder 108 so that the limiting lifting platform 106 rises along the upper extension guide column 103, thereby limiting the waste liquid storage bottle 401 on the limiting port 107.
