Abstract
The utility model discloses an indwelling needle fixing device suitable for mouse tail intravenous injection, particularly relates to the technical field of indwelling needle fixing, and comprises a core structure sleeve, a first shell and a second shell which are distributed up and down are arranged at the rear end of the core structure sleeve, and the core structure sleeve is used for fixing an indwelling needle for mouse tail intravenous injection. The inner wall of the first shell is of an arc-shaped groove design and is provided with a fixing assembly, namely, two symmetrically-distributed clamping plate structures are arranged in the arc-shaped groove, and guide rods are fixedly arranged on the sides, away from each other, of the two clamping plates. According to the mouse tail fixing device, the first shell and the second shell are matched, so that the mouse tail is fixed in a relatively stable and comfortable state, the intravenous injection indwelling needle on the mouse tail is stored through the arc-shaped groove in the first shell, an experimenter adjusts the clamping degree of the intravenous injection indwelling needle through the threaded rods on the two sides, and the mouse tail is fixed to the experimenter. Therefore, the stability of the intravenous injection indwelling needles of different specifications is improved.
