1. A catheter fixing assembly for fixing a catheter to the skin of a patient, wherein the catheter comprises a catheter body, a first catheter wing extending from a first side of the catheter body, and a second catheter wing extending from a second side of the catheter body opposite the first side, the catheter fixing assembly comprising:
a base, comprising:
an adhering surface for adhering to the skin of the patient;
a fixing surface, wherein a groove is defined in the fixing surface for accommodating the catheter body, and wherein the groove defines an axis;
first and second rotation shafts extending from the fixing surface on first and second sides of the axis, respectively, the second side of the axis being opposite the first side of the axis; and
first and second snaps on the first and second sides of the axis, respectively; and
first and second wing fixing portions rotatably attached to the first and second rotation shafts, respectively, wherein the first and second wing fixing portions each comprise:
a through hole for rotatably attaching to the respective first or second rotation shaft;
a wing accommodation slot for accommodating one of the first or second catheter wings; and
a tab for engaging with one of the first or second snaps;
wherein the first and second wing fixing portions are rotatable about the first and second rotation shafts, respectively, to transition the catheter fixing assembly between:
a first state in which the first wing fixing portion overlays the first catheter wing on the first side of the axis and the second wing fixing portion overlays the second catheter wing on the second side of the axis, thereby maintaining the catheter body in the catheter fixing assembly; and
a second state in which the first and second wing fixing portions are rotated away from the first and second catheter wings, respectively, thereby allowing the catheter body to be removed from the catheter fixing assembly;
wherein the first and second wing fixing portions are rotatable toward one another to transition the first and second wing fixing portions from the second state to the first state.
