Automatic venous transfusion control system and transfusion method thereof

Abstract

The invention relates to an automatic venous transfusion control system and a transfusion method thereof. The system includes at least one venous transfusion device (1), a detachably connected venoustransfusion control device (2) and an upper computer (3); when the upper computer (3) receives temperature data not in accordance with preset temperature data, a processing unit (19) sends a heating signal to a heating element (12) to maintain the temperature of a liquid in a liquid container at a constant value in accordance with the preset temperature data; when the upper computer (3) receives liquid drop speed data not in accordance with preset liquid drop speed data, the processing unit (19) sends a speed signal to a speed control device (15) to maintain the liquid drop speed data of falling liquid drops in a Murphy dropper (5) constantly equal to the preset liquid drop speed data; when the upper computer (3) receives a stop signal, the processing unit (19) sends a zero speed signal tothe speed control device (15) to make the adjustment state of a flow adjuster (7) changed to a zero-flow state.

Description

Technical field [0001] The invention belongs to the medical field, and particularly relates to an automatic intravenous infusion control system and an infusion method thereof. Background technique [0002] At present, most of the current infusion monitoring mechanisms in hospitals and medical institutions use manual methods, especially for the infusion monitoring in general wards, which are almost always checked by the patient's family or medical staff on a regular basis. The patient’s family members receive continuous infusions day and night. The summer is hot and the winter is cold. It is miserable. If you are negligent, you can’t find the abnormal situation of the infusion in time. , Leaking needles, air leakage, etc.). The risks caused by the infusion speed are the drugs according to their characteristics in order to achieve curative effect while avoiding side effects. There are requirements for drip rate, such as blood sugar and blood pressure lowering drugs. There is a ris...

AI Technical Summary

Problems solved by technology

This patent can automatically block the infusion line by the pressure tube head of the clamping mechanism after the infusion is completed to prevent blood backflow, but this patent does not solve the problem of low temperature of the liquid medicine, and cannot automatically control the infusion speed, and cannot be reused in multiple applications. On a disposable infusion set, the cost is high, the risk of wrong matching between the infused liquid and the patient cannot be avoided, the liquid can not be infused at a constant speed and temperature, and the gas cannot be prevented from entering the human body. There is no multiple measurement to prevent the air in the infusion tube from following the infusion. Tube into the human body, can not automatically complete multiple infusion processes under constant temperature and constant speed
