Indwelling needle extravasation monitoring and blocking device

Abstract

The invention provides a remaining needle extravasation monitoring and blocking device, and relates to the technical field of medical instruments.The remaining needle extravasation monitoring and blocking device comprises a monitoring assembly and a blocking assembly, the monitoring assembly comprises a fixing patch used for fixing a remaining needle, and the fixing patch is provided with a power module, a film pressure sensor, an indicator light and a control chip; the power module, the film pressure sensor and the prompting lamp are all connected with the control chip, the film pressure sensor is arranged on the side, facing the human skin, of the fixed application, the prompting lamp is arranged on the side, deviating from the human skin, of the fixed application, and the blocking assembly is connected with the control chip. When the indwelling needle is used for infusion exosmosis, tissues around blood vessels of a human body swell, so that pressure is applied to the thin film pressure sensor attached to the fixed application, and the prompt lamp is controlled to be turned on through the control chip to timely remind people around that the infusion exosmosis has occurred. When swelling is serious, the infusion process is automatically blocked, the extravasation degree is prevented from being further aggravated, and the guarantee for the safety of a patient is improved.

AI Technical Summary

Benefits of technology

This patented technology describes a system called Indwelling Needles Exclusion (IWEN) which uses special components made like a small pad or plate to fix the insertion point of the needle into place inside body cavity during medical procedures such as injection. These technical improvements improve the accuracy and reliability of this method while also reducing any potential harm caused due to excessive bleeding.

Problems solved by technology

This patented technical problem addressed in this patents relates to how to prevent excessive bleeding during an IV procedure while still allowing enough bodily liquids from entering into veins without causing discomforts such as skin ablation (bleed) and possible complications like arterial blockages.
