The invention relates to the technical field of medical care, in particular to a photoelectric double-sensing disposable infusion needle and a monitoring system thereof, and aims to solve the problemof low monitoring accuracy in the prior art. The photoelectric double-sensing disposable infusion needle mainly comprises a needle body, a base, an optical fiber penetrating through the needle body and the base, a groove from the center of the needle body to the outer surface, and a sensing interface, wherein a capacitance electrode is buried on two sides of the groove respectively to ensure thata liquid medicine can be positioned in the groove without being in contact with the capacitance electrodes; an electrode contact and an optical fiber interface are arranged in the sensing interface; the optical fiber extends downwards to the optical fib interface, and the capacitance electrode is electrically connected with the electrode contact through a lead, so that when the liquid medicine ismore, the change of the liquid level of the liquid medicine can be monitored in time by adopting optical measurement, and when the liquid medicine is less and the liquid surface of the liquid medicineenters the inside of the needle body, more accurate electrical measurement is adopted, so that the monitoring dimension, the monitoring accuracy and timeliness are improved, medical staffs can graspaccurate replacement alarm information, and the medical care efficiency is improved.
Description
technical field [0001] The application relates to the technical field of medical care, in particular to a photoelectric double-sensing disposable infusion needle and a monitoring system thereof. Background technique [0002] At present, when infusion is ill, the medical staff or the patient needs to pay attention to the liquid level of the liquid in the infusion bottle at all times, and call the medical staff to remove or replace the infusion container when the liquid is almost finished. Taking care of multiple patients at the same time, and there are many emergency departments in the hospital, it may not be possible to remove or replace the infusion container in time; and the patient himself may ignore the liquid level of the infusion container due to physical weakness and other reasons; The backflow of blood or the entry of air into blood vessels can adversely affect the patient's health. [0003] Although laser sensors can be used to monitor the position of the liquid le...
