Normal convenience.
Then, infusion bottle or infusion bag can be hung over infusion information acquisition terminal machine (i.e. infusion information adopted by medical staff
Collection unit 101) hook (hook in succession weighing sensor, have narration above, which is not described herein again) on, so as to start into
Row infusion.
Finally, in infusion process (after i.e. infusion starts), infusion information acquisition terminal machine (i.e. infusion information acquisition unit
101) continuous weight parameter, and least-squares algorithm (fitting) and Kalman filtering are combined, calculate (the infusion of transfusion state parameter
State parameter includes transfusion speed, infusion remaining time and residual drug), on the one hand, the transfusion state parameter can lead to
The display screen 105 for crossing infusion information acquisition terminal machine (i.e. infusion information acquisition unit 101) carries out real-time display, so as in ward
Medical staff, transfusion patient and families of patients etc. can understand transfusion condition in real time, adjusted particularly convenient for medical staff defeated
Liquid speed degree；On the other hand, the transfusion state parameter can be sent to server by ZigBee wireless network transmissions unit 201
It is stored in 301, and can be transferred in the display 402 of monitoring platform 401 and be shown by server 301, monitored
The display 402 of platform 401 is generally arranged at the position of nurse station, so as to nurse station nurse can be infused with real time inspection into
Degree, so that reasonable arrangement follow-up work, provides working efficiency；In addition, medical staff can also utilize 403 (PC machine of terminating machine
404, plate 405, mobile phone 406), by internet accessing server 301, thus can also with real time inspection transfusion state parameter,
Infusion progress is remotely understood and grasped so as to more convenient.
In more perfect scheme, monitoring platform 401 further includes alarm device, alarm device and 404 phase of server 301 or PC machine
Even, it can be near completion in infusion or unexpected terminate or when transfusion speed is excessive or transfusion speed is too small, sound an alarm
Sound or prompt tone avoid malpractice to remind medical staff to handle in time.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.
