Abstract

The invention discloses a portable medical transfusion alarming device, which comprises the following parts: sampling circuit, triggering control circuit and alarming circuit, wherein the case adapts the photopath sealing type, which avoids the light source interference; the sampling circuit adapts the composite photoelectric coupler, which contains colloid hollow calibrator on the bottom; the triggering control circuit contains controllable silicon, which transmits the gathered photoelectric signal into alarming signal precisely. The invention guarantees the patient safety, which lessens the labor strength for nursing personnel.

Description

technical field [0001] The invention relates to an electronic instrument for monitoring and alarming intravenous infusion, which belongs to a portable medical infusion alarming device. Background technique [0002] The clinical treatment of the hospital is the scene of rescuing patients during continuous infusion patients or sudden accident scenes, large-scale power outages caused by earthquakes and other natural disasters; patients who are rescued by military hospitals in modern wars often need continuous intravenous infusion, and During the infusion process when there is a shortage of medical staff, it is very easy to cause the liquid medicine to be empty or cause bubbles in the infusion line for some reason and cannot be detected in time. This will cause harm and pain to the patient, and it will be life-threatening in serious cases. Currently disclosed medical infusion alarm devices using photoelectric sensing technology, most of the photoelectric "transmitting-receiving...
