DETACHABLE DRUG LIQUID INFUSION DEVICE

WIPO Patent Application WO/2024/011696

A1

A detachable drug liquid infusion device, comprising a first case (1) and a second case (2). The first case (1) contains an infusion assembly (3) used for infusing a drug liquid into the body of a patient and an execution assembly (4) connected to the infusion assembly (3) and used for driving the infusion assembly (3) to infuse the drug liquid. The second case (2) contains a memory alloy driving assembly (5) detachably connected to the execution assembly (4) and a control assembly (6) electrically connected to the memory alloy driving assembly (5) and used for controlling the work of the memory alloy driving assembly (5). The first case (1) and the second case (2) are detachably assembled. The second case (2) as well as the relatively expensive control assembly (6) and memory alloy driving assembly (5) in the second case (2) can be recycled, such that the cost of repeated use is greatly reduced for the patient. In addition, a driving power is provided in the mode of heating memory alloy to deform, helping to miniaturize the device. Therefore, the device is easy to carry and use, has great applicability, and is suitable to widely popularize and use.
