Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an anti-dropout fixing device for an external drainage tube. Background Art

[0002] External drainage tubes such as ventricular and subdural drainage tubes are often used after neurosurgery. Usually, the external drainage tube is inserted subcutaneously and then led out from the skin to an external drainage bag. It is very important to keep the position of the drainage tube fixed after surgery and prevent it from slipping off, and to keep the drainage tube unobstructed.

[0003] The traditional method is to sew the external drainage tube directly on the skin after it is led out from the skin perforation, and then directly connected to the external drainage device after being bandaged with a dressing. Since the external drainage tubes in neurosurgery are usually thin and have smooth walls, the traditional fixation method requires the external drainage tube to be sewed directly on the patient's scalp, but this often causes the external drainage tube to shift or slip under the action of external forces.

[0006] Preferably, a slot extending in the radial direction is provided at the top of the shell, one end of the slot is connected to the hole center, and the other end of the slot extends to the edge of the shell.

[0007] Preferably: the outer wall of the shell is provided with a spiral groove, and the spiral groove is connected to the clamping groove.

[0008] Preferably, a plurality of limiting grooves are provided on the bottom side wall of the shell and located inside the spiral groove for connecting the adapter.

[0009] Preferably, the adapter comprises an inlet connector and an outlet connector, the inlet connector and the outlet connector are integrally formed, the inlet connector is a spiral port matching the external drainage tube, and the outlet connector can be adaptably connected to the external drainage bag.

[0010] Preferably, the adapter also includes a limit block and a handle, and the limit block and the handle are fixed between the inlet connector and the outlet connector.

[0011] Preferably, the clamping member comprises a clamping block and a positive clamping socket, and the positive clamping socket is matched with the negative clamping socket groove.

[0012] Preferably, the clamping block is also connected to an external drainage tube fixing clamping socket, an end of the external drainage tube fixing clamping socket away from the clamping block is provided with a bending structure, and the external drainage tube fixing clamping socket is provided with a clamping groove opening downward for fixing the external drainage tube.

[0013] Preferably, a bending structure is provided at one end of the fixing clamp of the external drainage tube away from the clamping block, and the bending angle is less than 90 degrees.

[0014] Technical effects and advantages of the utility model:

[0015] In the utility model, the external drainage tube can be fine-tuned by adjusting the position of the adapter in different limit grooves, so that the external drainage tube wrapped around the shell remains flat, and the position of the adapter after adjustment is fixed, and the position where the external drainage tube is connected to the inlet connector is stable.
