Rapid constant-pressure infusion control system and method

Abstract

The invention relates to a rapid constant-pressure infusion control system and method. The rapid constant-pressure infusion control system comprises a power supply control protection module, a driving control module, a pressure monitoring module, an infusion device and a control unit. The power supply control protection module provides electric energy for the driving control module according to the control of the control unit and cuts off the electric energy of the driving control module according to the control of the control unit; the driving control module drives the air pump to work according to the control of the control unit; the pressure monitoring module monitors the pressure in an air bag in the infusion device in real time and outputs a pressure feedback signal to the control unit; and the control unit is used for carrying out PID feedback adjustment on the air pump by adopting a PID method according to the pressure feedback signal so as to dynamically adjust the pressure in the air bag and realize rapid constant pressure. The PID feedback regulation is carried out by adopting a PID method, so that the pressure in the air bag in the infusion device can quickly reach a target pressure value, quick constant pressure and small pressure fluctuation are realized, the pressure oscillation is reduced, and the infusion effect is improved.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, more specifically, to a rapid constant pressure infusion control system and method. Background technique [0002] Infusion and blood transfusion (collectively referred to as infusion) is a commonly used clinical treatment method, especially when severe trauma, massive blood loss, and rescue of critically ill patients, rapid infusion is one of the important measures for first aid. In some cases, infusion can replenish water, electrolytes, and adjust pH balance; infusion can also replenish energy and nutrients needed by the body; blood transfusion can improve the body's oxygen-carrying capacity or improve the body's blood coagulation function, etc. Rapid pressurized infusion can quickly replenish fluid, maintain sufficient blood volume, and ensure the stability of water and electrolytes in the body, which is often an important measure for the operation to be carried out.

Problems solved by technology

[0003] In order to achieve rapid pressurized infusion to achieve the purpose of rapid rehydration, the current commonly used method is to use electric pressurized infusion method, but the existing electric pressurized infusion method has large pressure fluctuations and obvious pressure vibration during the pressurization process The effect is poor, and the target value cannot be reached at a faster speed, which leads to poor infusion effect
