[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0020] Please refer to Figures 1 - 3 , a thoracic drainage tube fixing device in this embodiment includes a connecting seat 1, a skin-friendly glue 2 is arranged outside the connecting seat 1, a through box 3 is arranged outside the connecting seat 1, an adjusting cover 4 is arranged outside the through box 3, and an adjusting structure 5 is arranged inside the adjusting cover 4.
[0021] The adjusting structure 5 includes a movable groove 501, a sliding groove 502, a sliding rod 503, a pressing wheel 504, a first spring 505, a clamping plate 506, a through hole 507, an N-shaped plate 508, a second spring 509, a pressing block 510, a clamping block 511 and a clamping groove 512. A movable groove 501 is opened at the top of the adjusting cover 4, a sliding groove 502 is opened inside the adjusting cover 4, a sliding rod 503 is slidably installed inside the sliding groove 502, a pressing wheel 504 is movably installed outside the sliding rod 503, a first spring 505 is fixedly installed inside the through box 3, a clamping plate 506 is fixedly installed outside the first spring 505, a through hole 507 is opened outside the adjusting cover 4, an N-shaped plate 508 is fixedly installed outside the adjusting cover 4, a second spring 509 is fixedly installed outside the N-shaped plate 508, a clamping block 511 is fixedly installed at the bottom of one end of the N-shaped plate 508, and a clamping groove 512 is fixedly installed outside the through box 3.
[0022] In Figure 1 , the side of the pressing wheel 504 passing through the adjusting cover 4 is inclined. When the pressing wheel 504 moves to the higher side outside the adjusting cover 4, the extrusion degree between the bottom of the pressing wheel 504 and the drainage tube is relatively loose.
[0023] In Figure 2 , the length of the clamping plate 506 can extend into the adjusting cover 4 when the through box 3 and the adjusting cover 4 are closed, that is, when the drainage tube passes through the through hole 507 opened in the through box 3 and the adjusting cover 4, it can always be in contact with the clamping plate 506.
[0024] In Figure 3 , the bottom of one end of the N-shaped plate 508 is close to the clamping groove 512, and the clamping block 511 at the bottom of the other end of the N-shaped plate 508 is clamped with the clamping groove 512. When the pressing block 510 is pressed, the N-shaped plate 508 is squeezed and the second spring 509 is compressed, so that the clamping block 511 can move and then move the adjusting cover 4, and the through box 3 and the adjusting cover 4 can be separated.
[0025] In summary, for the thoracic drainage tube fixing device, the skin-friendly glue 2 is attached to the outside of the patient's chest cavity. The penetration box 3 and the adjustment cover 4 are separated, and the drainage tube enters the inside of the penetration box 3. The drainage tube is fixed by the clamping plate 506. After the penetration box 3 and the adjustment cover 4 are closed, the bottom of the pressing wheel 504 will be attached to the drainage tube, so that the drainage tube can be double-fixed to prevent the drainage tube from detaching.
[0026] Moreover, for the thoracic drainage tube fixing device, when the drainage bottle needs to be replaced, the pressing wheel 504 can be rotated. During the movement of the pressing wheel 504, due to the change in the position of the pressing wheel 504, the degree of extrusion of the pressing wheel 504 on the drainage tube is different. Thus, when the drainage bottle is replaced, the drainage tube can be clamped to control the flow rate of the drainage fluid, solving the problem that the existing drainage tube is prone to accidental detachment during placement, resulting in the leakage of the drainage fluid to the drainage opening, and the drainage fluid can cause local skin infection. Therefore, during the treatment process, the thoracic drainage tube needs to be fixed to avoid slippage.
