The present invention provides a medical tube fixing device, which is used for fixing a medical tube, including a first clip, a latching member, and an elastic member. The first clip is fixed to the patient's clothing through a clamping method. The latch is connected to the first clip and has a latch slot. One end of the elastic member is connected to the latch and the other end has a fixing part. Among them, after the elastic member bypasses the medical pipeline and fixes the fixing part to the latching groove, it is in a state of being bound and fixed relative to the medical pipeline. With this, the medical tube fixing device can be quickly and easily fixed to clothing, and at the same time, it can adjust the tightness according to the size of the tube and has an excellent fixing effect relative to the medical tube, effectively preventing the patient's skin from being fixed by tape and other fixing components. This can lead to pressure or allergies, and to avoid medical dangers caused by twisting or compression of medical tubing.本創作提供一種醫療管路固定裝置,係供以固定一醫療管路,包含一第一夾固件、一卡掣件及一彈性件。第一夾固件供以透過夾持方式固定於病患衣物上,卡掣件與第一夾固件連接設置且具有一卡掣槽,彈性件一端連接設於卡掣件,另一端具有一固定部,其中,彈性件繞過醫療管路並使固定部卡固於卡掣槽後,即相對醫療管路形成綁縛固定之狀態。藉此醫療管路固定裝置即可快速簡易地固定於衣物上,同時又可因應管路大小調整鬆緊度並相對醫療管路具有極佳之固定效果,有效地防止病患皮膚因膠帶等固定元件而導致受壓或過敏,以及避免醫療管路扭折或壓迫造成病患之醫療危險。
