The invention discloses a hospital ward infusion automatic warning device, which comprises an on-site weight signal processing and transmitting unit, a nurse station main controller and a medicine bottle weighing device, wherein the medicine bottle weighing device is used for acquiring information of the weight of a medicine bottle and for transmitting the information to the on-site weight signal processing and transmitting unit; the medicine bottle weighing device comprises a main shaft, a main shaft supporting sleeve and the like; a hook for hanging the medicine bottle is arranged at one end of the main shaft, a blind hole for holding magnetic steel is arranged at the other end of the main shaft and a spring is sleeved in the middle of the main shaft; a Hall sensor is fixedly arranged above the magnetic steel and keeps a clearance from the magnetic steel; medicine liquid in the medicine bottle gradually reduces as infusion goes on, and the expansion amount of the spring changes, so that the main shaft is subjected to axial displacement relative to the main shaft supporting sleeve, a distance between the magnetic steel and the Hall sensor is changed and an output voltage signal of the Hall sensor changes as well. The warning device disclosed by the invention is simple in structure and is safe and reliable; and the warning device has the advantages that while the psychological anxiety and working strength of nurses are greatly reduced, patients are pacified, and the medical service quality of a hospital is improved.
Description
technical field [0001] The invention relates to the monitoring of infusion in a hospital ward, in particular to an automatic warning device for infusion in a hospital ward. Background technique [0002] There are many wards in the inpatient department of modern hospitals, and injections and infusions are the daily work that nurses have to do every day. However, due to the small number of nurses and the large number of patients, the nurses have to constantly check the situation in each ward, so as to replace the new medicine in time and re-inject or terminate the injection. If the original infusion bottle is not processed in time after it is emptied, it may cause blood to flow back into the infusion tube, causing medical accidents. Especially at night, when the patient is drowsy and no one is watching, the timely detection and disposal of the infusion will be very prominent. Today, when advocating the improvement of medical service quality, eliminating such hidden dangers h...
