Specifically, when the negative pressure inside the storage cylinder 1 is adjusted, the brake motor 213 works, and the output end rotates to drive the lower gear 215 to rotate, and the rotation of the gear 215 drives the gear 1 212 on one side to rotate. When the gear 1 212 rotates, it drives the lower wheel 208 to rotate, and the wheel 208 drives the wheel 1 206 to rotate through the belt 207, so that the wheel 1 206 drives the lower threaded rod 1 211 to rotate, and the threaded rod 1 21 When the second wheel 208 rotates, it will move the outer fixing plate 1 219 upward. The fixing plate 1 219 will drive the guide rod 210 on one side to move upward. The guide rod 210 will drive the bottom fixing plate 218 and the sealing plug 217 upward, thereby adjusting the negative pressure inside the storage cylinder 1. During the negative pressure adjustment process, the rotation of the second wheel 208 will synchronously drive the rotation of the second threaded rod 216 below. When the second threaded rod 216 rotates, it will drive the outer fixing plate 220 to move downward. When the fixing plate 220 moves downward, it will push the connecting plate 203 on one side to move downward. When the connecting plate 203 moves downward, it will push the bottom connecting block 223 to move downward inside the observation tube 201. When the connecting block 223 moves, it will drive the position of the caliper 226 on one side to adjust its position. Therefore, by observing the moving position of the caliper 226, it is convenient to observe the negative pressure inside the storage cylinder 1 during the adjustment process.

[0024] See Figure 10 The end of the liquid extraction tube 3 is provided with an external thread 10, and the inside of the liquid extraction head 4 is provided with an internal thread 12.

The medical staff sets the liquid extraction head 4 on the wound, sets the liquid extraction head 4 to cover the wound, and then sticks the bonding tape 13 on the outside of the wound to fix the liquid extraction head 4 as a whole.

[0025] The working principle of the negative pressure drainage device for breast tumor postoperative rehabilitation provided by the present invention is as follows: Step 1: When draining for postoperative rehabilitation, the medical staff sets the liquid extraction head 4 on the wound, sets the liquid extraction head 4 to cover the wound, and then sticks the adhesive tape 13 on the outside of the wound to fix the liquid extraction head 4 as a whole.

[0026] When extracting fluid, the medical staff opens the manual clamp valve, thereby opening the extraction tube 3 to extract the accumulated fluid, so that the accumulated fluid is extracted into the storage tube 1.

[0027] Step 2: When the negative pressure inside the storage cylinder 1 needs to be adjusted, the brake motor 213 works, and the output end rotates to drive the lower gear 215 to rotate, and the rotation of the gear 215 drives the gear 1 212 on one side to rotate. When the gear 1 212 rotates, it drives the lower wheel 208 to rotate, and the wheel 208 drives the wheel 1 206 to rotate through the belt 207, so that the wheel 1 206 drives the lower threaded rod 1 211 to rotate. When the threaded rod 1 211 rotates, it will mobilize the outer fixed plate 1 219 to move upward, and the fixed plate 1 219 will drive the guide rod 210 on one side to move upward, and the guide rod 210 will drive the bottom fixed plate 218 and the sealing plug 217 to move upward, thereby adjusting the negative pressure inside the storage cylinder 1.

[0028] Step 3: During the negative pressure adjustment process, the rotation of the wheel 208 will synchronously drive the rotation of the threaded rod 216 below. When the threaded rod 216 rotates, it will drive the outer fixed plate 220 to move downward. When the fixed plate 220 moves downward, it will push the connecting plate 203 on one side to move downward. When the connecting plate 203 moves downward, it will push the connecting block 223 at the bottom to move downward inside the observation tube 201. When the connecting block 223 moves, it will drive the caliper 226 on one side to adjust its position. Therefore, by observing the moving position of the caliper 226, it is convenient to observe the negative pressure inside the storage cylinder 1 during the adjustment process.

[0029] Compared with related technologies, the negative pressure drainage device for breast tumor postoperative rehabilitation provided by the present invention has the following beneficial effects: By setting the adjustment mechanism, the brake motor 213 works, the output end rotates to drive the lower gear 215 to rotate, the gear 215 rotates to drive the gear 1 212 on one side to rotate, and when the gear 1 212 rotates, it drives the lower runner 208 to rotate, and the runner 208 drives the runner 1 206 to rotate through the belt 207, so that the runner 1 206 drives the lower threaded rod 1 211 to rotate, and when the threaded rod 1 211 rotates, it mobilizes the outer fixed plate 1 219 to move upward, and the fixed plate 1 219 drives the guide rod 210 on one side to move upward, and the guide rod 210 drives the bottom fixed plate 218 and the sealing plug 217 to move upward, thereby adjusting the negative pressure inside the storage cylinder 1. During the negative pressure adjustment process, the rotation of the wheel 208 will synchronously drive the rotation of the threaded rod 216 below. When the threaded rod 216 rotates, it will drive the outer fixed plate 220 to move downward. When the fixed plate 220 moves downward, it will push the side connecting plate 203 to move downward. When the connecting plate 203 moves downward, it will push the bottom connecting block 223 to move downward inside the observation tube 201. When the connecting block 223 moves, it will drive the caliper 226 on one side to adjust its position. Therefore, by observing the moving position of the caliper 226, it is convenient to observe the negative pressure inside the storage cylinder 1 during the adjustment process. Therefore, when using the drainage device, it is convenient to adjust the negative pressure in the storage cylinder 1 according to actual usage needs.
