Description

Alarm blocking equipment for detecting liquid leakage of critically ill patient during transfusion

Technical Field

The invention relates to the technical field of medical instruments, in particular to an alarm blocking device for detecting liquid exudation of a critically ill patient during transfusion.

Background

The serious patients are easy to suffer from the condition of infusion medicine exosmosis due to the fact that the local vein wall generates chemical inflammatory reaction and the vascular permeability is increased because of long-term infusion of liquid medicine with high concentration, strong irritation and over normal osmotic pressure. And the severe patients cannot timely sense the liquid extravasation due to limited activity, disturbance of consciousness and other reasons, and nursing staff cannot ensure that the liquid extravasation condition is observed in the first time, so that the transfusion medicine extravasation causes adverse events such as local skin vascular necrosis, phlebitis, inflammatory injury of surrounding tissues and the like, and the burden of severe nursing is increased. Therefore, how to effectively monitor the venous fluid extravasation becomes a critical care problem which needs to be solved urgently.

The existing liquid extravasation prevention technology focuses on two methods, one is that an alarm device is connected to an infusion leather strip, and whether the liquid extravasation occurs is judged by monitoring the infusion speed; the other method is that the alarm device is connected to the puncture part for application, and whether the liquid extravasation phenomenon occurs is judged by monitoring the blood vessel pressure or the blood flow speed. The two methods have the effect of preventing liquid from seeping, but the alarm is connected to the transfusion leather strip, and whether the liquid seeping occurs is judged by monitoring the transfusion speed. The method of applying the alarm device to the puncture site increases the alarm accuracy by monitoring the blood flow velocity, the peripheral skin tension and the blood vessel pressure, but also increases the medical cost and cannot be recycled. And the two methods only stay in the alarm stage and cannot block the liquid extravasation at the puncture part at the first time, so that certain limitation still exists in the process of detecting the liquid extravasation.
