Transfusion system capable of controlling speed and achieving automatic replacing

Abstract

The invention relates to an automated transfusion system which comprises a transfusion group and a console. The console monitors the transfusion state of the transfusion group and switching-on and switching-off of transfusion, the transfusion group comprises at least one transfusion unit, each transfusion unit comprises current transfusion medicine, a catheter connected with the transfusion medicine, an electrically operated valve, a three-way valve and a transfusion tube, the end, inserted into a transfusion medicine container opening, of the catheter connected with the transfusion medicine is provided with a liquid level sensor, the inlet end of the electrically operated valve is connected with the catheter connected with the transfusion medicine, the outlet end of the electrically operated valve is connected with the three-way valve, and one of the output ends of the three-way valve is connected with the transfusion tube; the console is controlled through PLC programming, and the transfusion state is adjusted and controlled through PID according to collected liquid level sensor data. The automated transfusion system can control the transfusion speed stably and replace transmission containers automatically, the blood of a patient can be effectively prevented from flowing back to the transfusion tube, automatic medicine changing can reduce the workload of nurses, and the safety of transfusion is improved in all aspects.

Description

technical field [0001] The invention relates to the technical field of intravenous infusion medical equipment. Background technique [0002] Intravenous infusion is one of the most direct and effective treatment methods through intravenous infusion of drugs in clinical practice with rapid onset of action. According to reports, in 2009, my country's medical infusion was 10.4 billion bottles, equivalent to 8 bottles per capita. [0003] During the infusion process, the infusion speed is a problem that needs to be paid attention to. If the patient has heart or lung disease, the infusion rate should not be too fast. Too fast a drop rate can cause hypervolemia, increase the load on the heart, and cause heart failure or pulmonary edema. Excessive intravenous infusion of potassium chloride will not only cause local pain, but also cause hyperkalemia, manifested as limb weakness, dyspnea, arrhythmia and even cardiac arrest leading to death. Sodium nitroprusside, nitroglycerin and...
