The workload of the current medical field is getting heavier and heavier, but the ratio of nurses to patients cannot be increased relative to the workload. In order to facilitate the treatment of injectable drugs, patients are usually given intravenous drips when they are hospitalized. The nurse will set the patient's infusion flow rate according to the doctor's advice, estimate the time when the infusion is exhausted, and replace the infusion with a new one before the infusion is exhausted. If the infusion flow rate is abnormal (the flow rate is too fast) Or stop) or unscheduled re-administration, etc., the nurse should immediately go to the patient’s location to deal with the abnormal situation of the intravenous injection; therefore, the nurse should regularly or irregularly check the patient's intravenous drip, which will increase the number of nurses Workload.

Patient infusion includes intravenous injection and dosing injection. There are techniques for detecting intravenous injection using weight meter, infrared, electromagnetic induction, photocoupling and other methods.

The processing unit is connected to the measurement unit and the input unit, which can calculate the weight difference between the time points of the two measurement times before and after, generate the instant liquid weight of the liquid container based on the initial weight and the weight difference, and determine whether the instant liquid weight meets the notification conditions. If the judgment is yes , A notification signal is generated. The communication unit is connected to the processing unit, and the notification signal can be transmitted to the nursing information system via the local network or the Internet.

The processing unit 13 judges whether the instant liquid weight LWt _i meets the notification condition LW _alarm , if it is the case of measuring infusion, the notification condition is LWt _i ≦LW _alarm ; if it is the case of measuring drainage, the notification condition is LWt _i ≧LW _alarm . When the processing unit 13 determines that the instant liquid weight LWt _i meets the notification condition LW _alarm , the processing unit 13 generates a notification signal representing the replacement of the liquid container; when the processing unit 13 determines that the instant liquid weight LWt _i does not meet the notification condition LW _alarm , the processing unit 13 Continue to steps 1 to 4.

In the embodiment of detecting infusion, the medical staff enters a predetermined point velocity range (for example, 0.5-2 g/min), and the processing unit 13 automatically converts the flow rate of the non-predetermined drip velocity range into an abnormal flow rate range (greater than 2 g/min) Or less than 0.5 g/min) as the notification condition, the processing unit 13 generates the drip flow rate R _i =△Wt _i /△t according to the weight difference △Wt _i and the time difference △t (t _i -t _i-1 ) between the two measurement times, When the processing unit 13 determines that the drip flow rate is within the abnormal flow rate range (for example, 3 g/min or 0 g/min), the processing unit 13 generates a notification signal representing the abnormal injection. The weight difference △Wt calculated by the processing unit 13 for tens of seconds _{If i} is 0, it represents that the needle is dropped or the blood is returned after the intravenous injection, and the processing unit 13 further generates a notification signal representing the empty injection.

The notification signal includes light signals, sound signals and/or video signals such as the bed number, notification time, and notification content. The communication unit 14 is, for example, a circuit including signal conversion and communication functions, which can convert the notification signal into a data packet readable by the nursing information system, and transmit the notification signal to the nursing information system through wired or wireless connection to the area or the Internet 100. The nursing information system 100 is connected to the computer or communication device carried by the nursing staff, and can immediately notify the nursing staff to go to the ward to handle the notification event.

In the embodiment of detecting the discharge, the liquid container is a discharge bag, the initial weight of the discharge bag is 0, and the notification condition is the maximum liquid weight LW _alarm . When the processing unit 13 calculates the weight difference between the two measurement times △Wt _{i is} not At 0 o'clock, the processing unit 13 generates a drainage signal, and the communication unit 14 transmits the drainage signal and drainage time to the care information system 100 via the network; when the processing unit 13 determines that the real-time liquid weight is not less than the maximum liquid weight LWt _i ≧LW _alarm , The processing unit 13 generates a notification signal representing the replacement of the liquid container, and the communication unit 14 transmits the notification signal representing the replacement of the liquid container to the care information system 100 via the network. In this way, the workload of caring for severely ill patients after surgery can be greatly reduced, and the physiological state of such patients can be monitored in real time.
