The invention discloses a special liquid feeding driving device for an
infusion pump. According to the technical scheme, the special liquid feeding driving device for the
infusion pump comprises a shell, wherein a liquid
inlet channel and a liquid outlet channel are separately formed in two ends of the shell; a first lug which is close to the liquid
inlet channel and a second lug which is close tothe liquid outlet channel are arranged on the shell; a
silicon valve element is fixed on the shell and is provided with a first sheet and a second sheet; the first sheet is arranged at the end, whichis away from the liquid
inlet channel, of the first lug; the second sheet is arranged at the end, which is close to the liquid outlet channel, of the second lug; a
liquid storage space is formed by the shell and the
silicon valve element and positioned between the first lug and the second lug; when the first sheet is attached to the first lug, the liquid inlet channel is isolated from the liquidstorage space; and when the second sheet is attached to the second lug, the
liquid storage space is isolated from the liquid outlet channel. The special liquid feeding driving device for the infusionpump is further provided with a switch for
controlling attachment between the second sheet and the second lug, and the surface, which is away from the
liquid storage space, of the
silicon valve element faces a push rod of the
infusion pump. The special liquid feeding driving device for the infusion pump has the advantages that the infusion quantity can become stable, and stability of intravenous infusion is improved.
