Injection device and injection device assembly

Abstract

The invention relates to an injection device and an injection device assembly, and belongs to the field of injection devices. The injection device comprises a loading bin, a screw, a push rod rotatingbarrel and a push barrel, wherein the loading bin is provided with at least one discharging outlet, the push rod rotating barrel can move in the direction close to or away from the loading bin, and the push barrel is provided with a linkage pulling ring. The screw is configured to move in the straight line direction so as to discharge materials in the loading bin from the discharging outlets, thepush barrel is configured to drive the linkage pulling ring to rotate in the first direction when the push rod rotating barrel moves towards the direction close to the loading bin, and the linkage pulling ring is configured to drive the screw to move in the straight line direction when rotating in the first direction. The injection device can precisely control the injection amount of the materials to meet the needs of use. The invention further provides the injection device assembly comprising the injection device.

Description

technical field [0001] The invention relates to the field of injection devices, in particular to an injection device and an injection device component. Background technique [0002] Medical personnel often use injection devices to hold drugs, so as to maintain the shelf life of drugs and perform accurate injections when needed. For example, syringes are such commonly used injection devices, but syringes are often used due to the user's hand Shaking or observation factors make it impossible to accurately inject a predetermined amount of medicine, and it is difficult to meet the needs of some precise injection of medicine. [0003] Therefore, there is a need for an injection device capable of accurately determining the injection volume to meet the requirements of use. Contents of the invention [0004] The object of the present invention is to provide an injection device, which can accurately control the injection volume of materials to meet the needs of use. [0005] Anot...
