[0022] See also Figure 1-Figure 2In a preferred embodiment of the present invention, a head drainage tube 2 wound compression device includes a headgear net bag 1, which is fixed to the patient's head by a restraint 11. The headgear net bag 1 has a mesh for the drainage tube 2 to pass through. The headgear net bag 1 is detachably mounted with a fixing device for fixing the drainage tube 2 to the headgear net bag 1, and the fixing device includes a compression airbag 31, a first fixing block 32 and a second fixing block 33. The compression airbag 31 is an annular structure for the drainage tube 2 to pass through, and its outer ring diameter is larger than the mesh aperture of the headgear net bag 1. The compression airbag 31 is arranged on the inner side of the headgear net bag 1, which is connected to the inflation tube, and the inflation tube is not One end connected to the compression airbag 31 is passed through the mesh of the headgear net bag 1 and can be detachably connected to an external air source device. After inflation is completed, the external air source device can be removed and there is no need to connect to the external air source device for use; the first fixed block 32 is movably passed through the mesh of the headgear net bag 1, one end of which is located on the inner side of the headgear net bag 1 and is connected to the compression airbag 31, and the other end of the first fixed block 32 is located on the outer side of the headgear net bag 1, and the other end is detachably connected to the second fixed block 33. Both the first fixed block 32 and the second fixed block 33 are provided with a through hole for the drainage tube 2 to pass through; when the second fixed block 33 is connected to the first fixed block 32, the first fixed block 32 clamps and fixes the drainage tube 2. When in use, the compression airbag 31 and the first fixing block 32 are placed on the drainage tube 2, and then the headgear net bag 1 is put on the patient's head, and the end of the drainage tube 2 that is not connected to the patient's head is passed through the through hole of the second fixing block 33, and the end of the first fixing block 32 that is not connected to the compression airbag 31 is passed through the nearest mesh hole of the headgear net bag 1, and the headgear net bag 1 is fixed to the patient's head using the restraint 11, which can be a rope, a belt, etc., and can be fastened to the head by tying a knot or Velcro, etc. The net bag 1 is put on to fix it, and then the second fixing block 33 is connected to the first fixing block 32, so that the first fixing block 32 clamps and fixes the drainage tube 2 to prevent the drainage tube 2 from falling off. Finally, the compression airbag 31 is inflated by an external air source device. After the compression airbag 31 is inflated, it compresses the area around the wound where the drainage tube 2 is inserted. At the same time, the compression airbag 31 and the second fixing block 32 clamp the inside and outside of the headgear net bag 1, thereby achieving the purpose of fixing the drainage tube 2 on the headgear net bag 1 and compressing the area around the wound.

[0023] Preferably, the first fixing block 32 is a tubular structure, and its tube hole is a first through hole. The first fixing block 32 is located on the end portion of the outside of the headgear net bag 1, and two or more clamping blocks 322 are arranged at intervals. The clamping blocks 322 are arranged around the center line of the first through hole 321. The thickness of each clamping block 322 gradually decreases from one end connected to the first fixing block 32 to the other end; the second fixing block 33 is a hollow tubular structure, and the through hole on the second fixing block 33 is a second through hole 331. The interior of the second fixing block 33 has a threaded section 332, a locking section 333 and a second through hole connected in sequence. 331, the second fixing block 33 is threadedly connected to the first fixing block 32 via a threaded section 332. The locking section 333 is located between the threaded section 332 and the second through hole 331. The locking section 333 is in the shape of a gradually tapering trumpet, with the end with the larger trumpet opening connected to the threaded section 332. Preferably, the diameter of the end with the smaller trumpet opening of the locking section 333 is equal to the aperture of the second through hole 331. When the threaded section 332 is threadedly connected to the first fixing block 32, the locking section 333 presses the clamping block 322 toward the center of the drainage tube 2 to clamp and fix the drainage tube 2, thereby fixing the drainage tube 2 to the headgear net bag 1. More preferably, the clamping block 322 is evenly arranged around the end of the first fixing block 32. The even surrounding can make the clamping force more uniform and ensure the stability of the clamping fixation. In addition, an anti-slip structure 334 is provided on the outer surface of the second fixed block 33. When the second fixed block 33 is rotated so that it is threadedly connected to the first fixed block 32, the anti-slip structure 334 can enhance the friction between the hand and the second fixed block 33, prevent sliding, and facilitate connection. In this embodiment, the anti-slip structure 334 preferably adopts anti-slip grooves. Those skilled in the art can also choose other structures with anti-slip effects such as anti-slip rubber according to actual needs.

[0024] In order to better connect the compression airbag 31, in this embodiment, a connecting block 323 is provided on the end of the first fixing block 32 that is not connected to the second fixing block 33. The size of the connecting block 323 is larger than the aperture of the mesh, and a third through hole 312 is provided in the middle thereof for the drainage tube 2 to pass through. The third through hole 312 and the first through hole 321 are coaxially arranged. The connecting block 323 and the second fixing block 33 are respectively located on the inner and outer sides of the headgear net bag 1, and the connecting block 323 is located between the first fixing block 32 and the compression airbag 31. The first fixing block 32 is connected to the compression airbag 31 through the connecting block 323, which increases the contact surface and makes the connection more stable. In addition, the first fixing block 32 and the connecting block 323 are an integrally formed structure, which makes the whole structure stronger and less prone to damage.

[0025] Preferably, the side of the compression bag 31 not connected to the second fixing block 33 is covered with skin-friendly cotton 311. The skin-friendly cotton 311 is a ring-shaped structure for the drainage tube 2 to pass through. The provision of the skin-friendly cotton 311 prevents the compression bag 31 from directly contacting the patient's skin, reducing patient discomfort. In this embodiment, the skin-friendly cotton 311 is detachably connected to the compression bag 31 via Velcro, making it easy to replace the skin-friendly cotton 311 as needed.

[0026] The above description is a detailed description of the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
