Liquid injection monitoring and liquid injection control method, device and system

Abstract

The invention discloses a liquid injection monitoring and liquid injection control method, device and system. The liquid injection monitoring method comprises the steps that a host obtains the liquid injection weighing data of liquid in a liquid injection container in real time, and the liquid injection amount injected into a human body is determined; the host acquires the first collected liquid weighing data of the liquid collected in a first recycling container connected with a treatment instrument and the second collected liquid weighing data of the liquid collected in a second recycling container connected with a collecting film in real time, and the amount of liquid discharged out of the human body is determined according to the first collected liquid weighing data and the second collected liquid weighing data; according to the liquid injection amount and the liquid outlet amount, based on a preset loss compensation principle, the liquid absorption amount absorbed by the human body is determined. According to the present invention, the absorption amount of liquid absorbed by the human body can be monitored and accurately determined in real time, and the treatment risk caused by liquid entering human body blood circulation is effectively avoided.

Description

Technical field [0001] The present invention relates to the field of medical devices, and more particularly to a solution monitoring and control method, apparatus, and system. Background technique [0002] In gynecological hysteroscopic surgery, it is necessary to use a large amount of expansion of the uterus and rinse to the uterus, so that the sub-uterine cavity is sufficiently expanded to provide good visual space for hysteroscopy. During the long-time echoconus, a part of the beef Palace liquid will enter the patient's blood through the surface of the uterine regions, and the liquid is introduced into the human body blood circulation if too much liquids enter the human body. Severe complications such as low sodama, hydrozine poisoning, endangers the life of patients. In order to ensure the safety of the patient, it is necessary to control the amount of liquid in the bleacher in the human blood circulation during the operation. [0003] At present, although it has begun to con...

AI Technical Summary

Problems solved by technology

[0003] At present, although we have begun to consider and pay attention to the amount of liquid used for uterine distension entering the human blood circulation during the operation, it is generally only based on the observation of the patient during the operation and the rough judgment based on the experience of the doctor. When the doctor thinks When the patient has absorbed too much fluid for distending the uterus, the operation will be stopped to ensure the safety of the patient’s life. This method cannot accurately determine the amount of fluid used for distending the uterus entering the blood circulation of the human body; The liquid is weighed and judged according to the amount of recovered liquid, but the recovered liquid will inevitably be lost and spilled, and the recovered liquid may be dumped or overflowed due to the capacity of the recovery bucket, so this method cannot accurately judge The amount of liquid used for distending the uterus entering the blood circulation of the human body

In the prior art, there is no effective real-time and accurate monitoring of the amount of liquid absorbed by the human body during the operation, and it is impossible to avoid the treatment risk caused by the liquid used for uterine distension entering the blood circulation of the human body
