Abstract
Description
Technical Field
[0001] This utility model relates to the field of infusion device technology, and in particular to an infusion set that prevents detachment. Background Technology
[0002] An infusion set is a common medical consumable. After sterilization, it establishes a channel between the vein and the medication for intravenous infusion. This product is used in conjunction with a disposable intravenous infusion needle and is primarily for clinical gravity-feed infusion. Its working principle is that, under atmospheric pressure, the liquid in the bottle flows through a thin infusion tube into the drip chamber. When the water column pressure in the drip chamber exceeds the venous pressure, the liquid in the bottle flows through the tube into the vein.
[0003] Traditional infusion sets often face the problem of the puncture needle falling off the infusion bottle or bag due to the patient turning over, stretching, or other unconscious movements. Although some existing infusion set designs use auxiliary devices to reduce the risk of needle dislodgement, different shapes of infusion bottles or bags may be required for different patients and treatment scenarios. Each size of infusion container requires a separately designed anti-dislodgement device of different lengths, which reduces the versatility and adaptability of anti-dislodgement products. Therefore, we propose an anti-dislodgement infusion set. Utility Model Content
