Abstract

The present application relates to an application-type infusion device, which comprises a casing body, a storage and infusion mechanism, a needle holder, an injection needle, an operating unit, an elastic part and a first guiding part, wherein an accommodating cavity is formed in the casing body, a distal end surface of the casing body that is close to the skin of the user is used to affix to the skin surface of the user, the storage and infusion mechanism is used to store and deliver a drug liquid to the injection needle, the first guiding part is configured to extend between a distal end direction close to the skin of the user and a proximal end direction facing away from the skin of the user, the needle holder sleeves over the periphery of the first guiding part, and the elastic part is disposed between the casing body and the needle holder. According to the present application, under the elastic restoring force applied by the elastic part, the needle holder may automatically remove itself together with the injection needle from the skin with convenient and rapid removal operation. In addition, the needle holder drives the injection needle to move between the distal end direction and the proximal end direction, so the injection needle is capable of being removed perpendicularly to the skin surface, thus preventing secondary damage to the skin.
