Transfusion supervising device

Abstract

A transfusion supervising device belongs to the medical monitor field. a light beam emitter 1 and a photosensitive element array 2 are respectively installed above a transfusion dropper liquid level at two sides of the transfusion dropper; a turbidity aberration detection module 3 is installed under the transfusion dropper liquid level and at the same side of the photosensitive element array 2 so that the light ray directionally emitted by the light beam emitter 1 can be received by the photosensitive element array 2 after being reflected by the liquid level inside the transfusion dropper and can be received by the turbidity aberration detection module 3 after being refracted by the liquid level inside the transfusion dropper; the infusion rate of the liquid medicine and the liquid level inside the transfusion dropper are detected by the photosensitive element array 2; the types and quality of liquid medicine are judged by the turbidity aberration detection module 3. The infusion rate, kinds and quality of liquid medicine can be monitored by the device of the invention in real time; the remaining time and remaining amount of liquid medicine are calculated and uploaded so as to realize remote control of infusion rate; when the infusion is completed or there is problem about the kinds of liquid medicine, the infusion can be safely stopped.

Description

technical field [0001] The invention relates to the field of medical monitoring, in particular to an infusion monitor. Background technique [0002] According to statistics from the China Safe Injection Alliance, 390,000 people die from unsafe injections every year in China. Infusion is a commonly used injection method, and its characteristics are: the process lasts for a long time, and in most cases, it does not need to be accompanied by medical staff, but medical staff must go to the hospital immediately for needle insertion, fluid replacement, and needle removal. Especially at the end, if the medical staff can't deal with it in time, the liquid medicine will run out, which will cause the patient's venous blood to return. If the gas entering the infusion catheter below the dropper is not noticed, it may be injected into the vein with the liquid medicine after changing the liquid, causing serious harm to the patient. Unnecessary pain and safety hazard. And in an emergency...

Problems solved by technology

At the same time, because it is difficult for medical staff to predict the time when the controllable medicinal liquid will be infused, the nursing work of medical staff lacks planning and order.
