Embodiment Construction

[0060] As mentioned above, the connection structure between the drive wheel and the screw rod of the prior art infusion device is complicated, resulting in a relatively large volume of the infusion device, high cost, and poor user experience.

[0061] In order to solve this problem, the present invention provides a drug infusion device. The drive wheel assembly of the infusion structure is provided with a movable block. When the movable block is in an open state, the screw rod does not engage with the drive wheel assembly, and the screw rod can be in the drive wheel assembly. The component slides, and the injection can be completed by using the thrust generated during the injection process, without the assistance of other components, the structure is simple, the cost is low, and the volume of the infusion device is small; when the movable block is in the closed state, the screw is engaged with the driving rod, and the screw Only when the driving force is generated by the rotati...

Abstract

The invention discloses a patch type medicine infusion device which comprises an infusion structure, and the infusion structure comprises a medicine storage cylinder which is used for containing medicine to be infused and is internally provided with a screw and a piston connected with the screw; the driving wheel assembly is in threaded connection with the screw rod, the driving wheel assembly comprises a driving wheel body and a movable block, the driving wheel body and the movable block are in operable connection, when the movable block is in an open state, the screw rod is not engaged with the driving wheel assembly, and when the movable block is in a closed state, the screw rod is engaged with the driving rod; the control structure is electrically connected with the infusion structure; and the sticky patch is used for sticking the control structure and the infusion structure on the skin surface. The infusion structure driving wheel and the screw rod are simply connected, the cost is low, the size is small, and the user experience is good.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of and claims priority to the following patent application: PCT patent application filed on January 5, 2021, application number PCT / CN2021 / 070207. technical field [0003] The invention mainly relates to the field of medical devices, in particular to a patch type drug infusion device. Background technique [0004] The pancreas in a normal human body can automatically monitor the glucose level in the human blood and secrete the required insulin / glucagon automatically. In diabetic patients, the pancreas does not function properly and cannot secrete insulin normally. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function, and diabetes is a lifelong disease. At present, there is no cure for diabetes by medical technology, and the occurrence and development of diabetes and its complications can only be controlled by stabilizing blood sugar. [0005] People wit...
