Problems solved by technology

[0005] However, in multiple operations, the traditional liquid stop clamp mechanism is prone to wear and tear of components during switching, resulting in deterioration
Additionally, when the clamp mechanism is not properly positioned, the clamp mechanism will struggle to clamp the infusion line, causing medical fluids to flow through the infusion set in an undesired manner
[0006] In addition, traditional infusion sets have more connecting parts, which increases the production and assembly costs of the infusion set

Abstract

The present application provides an infusion device comprising: a body configured to receive an infusion line and comprising a pumping mechanism configured to flow a medical fluid through the infusion line received in the body; a pump door assembly configured to be connected to the body for closing the body, and configured to fix the infusion line in place in the body, the pump door assembly including a snap member including: snap projections disposed at both ends of the snap member in a longitudinal direction of the snap member, the snap projections being configured to engage the infusion line in the body; the top surface of the buckle protruding part is shaped to be suitable for receiving an infusion pipeline; and the groove is located in the middle position between the buckle protruding parts and is configured to be sunken to be lower than the buckle protruding parts in the height direction of the buckle component.

Description

technical field [0001] The present application relates to infusion devices for delivering medical fluids, such as drugs or nutritional solutions, to patients. Background technique [0002] Infusion devices, such as volumetric (peristaltic) infusion devices, are used to precisely deliver medical fluids, such as drugs or nutritional solutions, to a patient at a predetermined rate. An infusion line passing through an infusion set in which a pumping mechanism, for example in a peristaltic manner, is infusion, is connected at one end to, for example, a container containing a medical fluid and at the other end to a patient. A pumping force is applied to the infusion line, causing the fluid to be delivered through the infusion line toward the patient. [0003] Typically, in order to better secure the positioning of the infusion line within the infusion set, a snap-fit ​​feature is provided within the infusion set for securing the infusion line in place. However, on the one hand, ...
