A warming and squeezing device for liquid medicine comprising a housing, upper heating fins and a heating and squeezing assembly is disclosed. Wherein the housing includes an upper casing and a lower casing for the upper casing to cover and connect thereto, and the upper heating fins connect to a bottom surface of the upper casing, and the heating and squeezing assembly includes an air bag, lower heating fins connecting to the upper side of the air bag for forming a receiving space between the upper and lower heating fins to receive and heat the medicine bag, and an air compression device communicating to the air bag the air bag is disposed between the lower heating fins and the lower casing, so that when the medicine bag is heated to a predetermined temperature, the air bag could be inflated by the compression of the air compression device to upwardly push and press the lower heating fins for squeezing the medicine bag and discharging the liquid medicine.一種藥液加溫擠壓裝置,係包括外殼、上加熱片以及加熱擠壓組件。其中,該外殼包括上殼體及下殼體,上殼體蓋合並連結於下殼體之上方,上加熱片連結於上殼體之底面,而加熱擠壓組件包括下加熱片、氣袋及連通氣袋之空氣加壓裝置,下加熱片結合於氣袋之上方,下加熱片及上加熱片之間形成一容置空間,供容納並對藥液袋進行加熱;而氣袋係定位於下加熱片與下殼體之間,藉此,當藥液袋加熱至預定之溫度時,經由空氣加壓裝置之加壓,即可使氣袋充氣,從而使氣袋向上推壓下加熱片,以擠壓藥液袋,讓藥液袋內之藥液向外流出。1‧‧‧藥液加溫擠壓裝置2‧‧‧外殼21‧‧‧上殼體211‧‧‧上容置空間22‧‧‧下殼體221‧‧‧下容置空間23‧‧‧樞軸3‧‧‧上加熱片4‧‧‧加熱擠壓組件41‧‧‧下加熱片42‧‧‧氣袋43‧‧‧空氣加壓裝置44‧‧‧容置空間5‧‧‧基座51‧‧‧樞軸6‧‧‧驅動裝置61‧‧‧齒輪62‧‧‧螺桿63‧‧‧馬達
