The course of work of the present embodiment is as follows:
The dropping bottle of infusion is hung on hook I 12 first, then again hangs over hook II 13 on infusion support, power supply is opened and opens
11 are closed, power supply indicator 4 lights, and opens host computer PC, then press start button I 7, the pressure of terminal data acquisition and monitoring device
Remaining drop weight detects in 2 pairs of bottles of force snesor, and sends data to CC2530 chip main control module I
CC2530 chip 9, in dropping bottle liquid weight and liquid drip speed be monitored, in normal monitoring, host computer
The infusion alarm software interface of PC can show drop flow velocity, transfusion time, transfusion state information, and work as and detect transfusion liquid
When residual mass is smaller or flow velocity is abnormal, slave computer is alarmed by buzzer 1 and LED alarm lamp 5, while host computer PC is logical
It crosses voice and pop-up reminds professional's processing, after infusion, press reset button I 10, restore default conditions.
Embodiment 2: the present embodiment structure with embodiment 1, the difference is that, the slave computer and host computer of the present embodiment away from
It is close from relatively, do not have to connect by router-module, the terminal data acquisition of the slave computer and the nothing of monitoring device and host computer
Line signal receives coordinator and is directly connected to.
The present embodiment, which passes through, judges that the weight for acquiring and being sent into CC2530 chip 9 for the first time determines drop initial value, works as acquisition
Data by multiplied by conversion coefficient be converted to weight again divided by fluid density be greater than 500mL when, CC2530 chip 9 is automatically by point
The initial value of drop becomes 500mL, when acquisition data multiplied by conversion coefficient be converted to weight divided by fluid density be greater than 250mL and
When less than 500mL, the initial value of drop will be become 250mL automatically by CC2530 chip 9, similarly be by judgement setting initial value
100mL or 50mL has been automatically performed setting drop volume Vb, monitoring can be realized by pressing beginning start button I 7, lead to
It crosses CC2530 chip 9 and judges the variation delta m for measuring weight in regular hour Δ t, to obtain the liquid within the Δ t time
Drip speed is v=Δ m/ Δ t(g/s).Simultaneously can be more intuitive in view of directly displaying amount of droplets, when medical staff is upper
When machine PC selection is with the display of amount of droplets display pattern, if setting fluid density ρ, the volume of every drop of liquid is Vm in cyclopentadienyl phenanthrene pipe, then
It take (drop/s) as liquid drop speed Vd=Δ m/ (ρ * Vm* Δ t) (drop/s) of unit.If the quality measured in real time is Vn, by real-time
The quality Vn/Vb*100% measured can dynamically check current residual drop accounting, and when accounting is less than some given value or Vd is small
Triggering alarm buzzer 1 is alarmed when some given range, and LED alarm lamp 5 becomes red from green, meanwhile,
When patient temporarily moves, when patient occur and taking away infusion bottle, alarm detects drop weight suddenly change, and amplitude of variation
When larger, state is set to halted state automatically within a certain period of time, after patient returns to corresponding position, infusion bottle is hung again
When on the hook of alarm lower end, state is automatically converted to monitor state and continues to supervise by alarm if being less than the stipulated time
Control notifies related personnel to handle if exceeding schedule time or starting buzzer warning if carry again without drop bottle for a long time.
The reception of wireless signals coordinator receives the data from slave computer and is passed data by serial communication module
Host computer PC is transported to, after the serial port selection in the infusion alarm software in host computer PC, clicking opening serial ports is
Host computer configuration can be achieved, infusion alarm software can read the data in corresponding serial port by MSComm control, and will count
In file according to the corresponding creation of write-in.The data of each slave computer can allow in host computer by selecting corresponding group number and seat in the plane number
Position is machine-readable to take the corresponding file data in corresponding seat in the plane, and data are shown by coordinate curve mode, when detecting data exception
When or drop will be finished, can pop up pop-up and issue voice prompting around medical staff handle in time.
Specific embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned realities
Example is applied, it within the knowledge of a person skilled in the art, can also be without departing from the purpose of the present invention
It makes a variety of changes.
