Description

Technical Field

[0001] The present application belongs to the technical field of infusion sets, and in particular relates to an anti-falling infusion set. Background Art

[0002] In clinical treatment and patient transport, patients often require infusion therapy. An infusion set uses a puncture needle to pierce the rubber stopper of an infusion bag or bottle to drain the medication and administer it to the patient. Existing infusion devices use a simple connection between the bottle and the puncture needle. This can cause traction on the infusion set when children, for example, turn over, walk, or use the restroom. This can easily cause the set to fall off. To address this issue, a drop-resistant infusion set is proposed. Utility Model Content
