AI Technical Summary

Technical Problem

During storage, transportation and intraoperative operation, existing temperature-sensitive nanogel embolizers are prone to phase change due to factors such as ambient temperature and operator grip, which affects product performance and surgical success rate.

Method used

A syringe is designed, with a heat insulation part provided on the outside, including a vacuum interlayer and a heat insulation gasket, which effectively insulates heat and prevents phase change of temperature-sensitive nanogel embolizers from being touched by ambient temperature and human body.

Benefits of technology

Through the design of the thermal insulation part, the stability of the temperature-sensitive nanogel embolizer is significantly improved, ensuring its performance stability during transportation, storage and intraoperative operation, thereby improving the success rate of the operation.

Abstract

The present invention relates to the field of interventional therapy technology, and discloses a vascular embolization treatment system based on a thermosensitive nanogel embolic agent, comprising a thermosensitive nanogel embolic agent and a syringe, wherein the thermosensitive nanogel embolic agent is pre-filled in the syringe, and a heat insulating portion is provided on the outside of the syringe. The thermosensitive nanogel achieves long-term conformal embolization from small blood vessels to large blood vessels through temperature-induced sol-gel phase transition. The present invention provides a heat insulating portion on the outside of the syringe, which plays a good heat insulating role, avoids the situation where the thermosensitive nanogel embolic agent causes phase change due to ambient temperature and human body touch, provides convenience for the transportation and storage of the thermosensitive nanogel embolic agent, makes the thermosensitive nanogel embolic agent more stable during surgery, and improves the success rate of the surgery.
