Detailed Description

The embodiment provides a technical scheme:

as shown in figure 1, the auxiliary fixing device for the infusion needle comprises an application 1 adhered to the skin of a patient, a longitudinal telescopic fixing strip 31, a transverse telescopic fixing strip 33 and a compression hemostasis mechanism for compression hemostasis after infusion is finished; the number of the longitudinal telescopic fixing strips 31 is two, the longitudinal telescopic fixing strips are respectively arranged and in sliding telescopic connection with the application 1, and two ends of the transverse telescopic fixing strip 33 are respectively fixed with the two longitudinal telescopic fixing strips 31; the hemostasis by compression mechanism is including fixed setting in applying ointment or plaster 1 upper end first fixed column and the taut fixed strip 21 of hugging closely with puncture department, correspondingly, the upper end of horizontal flexible fixed strip 33 is equipped with second fixed column 41, the one end and the first fixed column rotatable coupling of taut fixed strip 21, the other end can dismantle with second fixed column 41 and be connected.

As shown in figure 1, the middle part of the application 1 is provided with an arc-shaped fixing groove 11 which is matched with the infusion line to be embedded and fixed. In order to prevent the needle from shaking due to the shaking of the infusion line in the actual infusion process, the application 1 is provided with an arc-shaped fixing groove 11 which can fix one end of the infusion line close to the needle.

In this embodiment, the first fixing column includes a lower fixing column 13, an upper fixing column 14 and a connecting rod, two ends of the connecting rod are respectively fixed with the lower fixing column 13 and the upper fixing column 14, and a rotating hole adapted to the connecting rod is arranged at an end of the tightening fixing strip 21; the middle part of first fixed column is equipped with the logical groove of adaptation infusion line embedding, leads to the groove and corresponds with arc fixed slot 11 and link up.
