HT, the fastest value V of normal infusion speed
MaxWith normal infusion speed be worth V the most slowly
Min
Second step: select by keyboard 3-2, the beginning monitor procedure, when light source was not enough, a LED lamp 1-2 and the 2nd LED lamp 2-2 opened;
The 3rd step: the first photographic head 1-1 obtains the infusion bottle video image, and the second photographic head 2-1 obtains the Perfusion drip funnel video image, and these two images are sent to the embedded system processing device 3-1 of monitoring infusion terminal 3 respectively by holding wire 4;
The 4th step: embedded system is handled device 3-1 and is read the infusion bottle video image and the process Treatment Analysis of infusing, and judges whether transfusion is near completion, and sends transfusion if transfusion is near completion and finishes warning message; Transfusion process Treatment Analysis concrete steps are: embedded system is handled device 3-1 and is located the infusion bottle zone automatically, obtains metal line and infusion bottle bottom wheel profile, calculates the distance H of liquid level and infusion bottle bottom, as H＜H
MinThe time, send the warning information that transfusion is near completion;
The 5th step: embedded system is handled device 3-1 and is read the Perfusion drip funnel video image and carry out the transfusion speed Treatment Analysis, judges that transfusion speed is normal, too fast or slow excessively, if too fast or slow excessively, then sends the transfusion speed warning message; The transfusion speed Treatment Analysis is specially:
(1) embedded system handle device 3-1 at the same time △ t read each frame Perfusion drip funnel video image, and the Perfusion drip funnel video image that reads is made gray processing handles, wherein 0.1s＜△ t＜0.2s;
(2) the adjacent two frame Perfusion drip funnel video images of calculus of finite differences after to gray processing are done difference processing between application of frame, the gradation of image value of two frame picture same positions is asked poor, and take absolute value, and obtain difference image;
(3) according to threshold value difference image being carried out binary conversion treatment and obtain black white image, is total pixel value R of white in the statistics black white image;
(4) with total pixel value R and predefined total pixel value low threshold R
LTWith total pixel value high threshold R
HTCompare:
If R
LT＜R＜R
HT, record the frame number of this Perfusion drip funnel video image, and deduct the frame number of the Perfusion drip funnel video image of last record, obtain the difference △ n of frame number, calculating liquid drop speed according to the difference △ n of interval △ t and frame number is transfusion speed V, V=1min/ (△ t * △ n), and change (5) over to;
If R＜R
LT, then the liquid level vibrations do not take place in explanation, if R〉and R
HT, then explanation has unusual interference; These two kinds of situations are then abandoned this inter-frame difference result, do not record the frame number of this Perfusion drip funnel video image, return (1) and continue to read the dropping funnel video image;
(5) judge the transfusion speed V that obtains in (4), if V〉V
MaxPerhaps V＜V
Min, then send the transfusion speed warning message.
The 6th step: the warning message of the 4th step with the 5th step is shown on the LCD screen, buzzer 3-4 sends buzzing simultaneously, the 3rd LED lamp 3-5 flicker, and by network interface 5 warning message is sent to nurse's control station, be convenient to the abnormal information that nurse's control station in time obtains all monitoring infusion devices, in order in time handle.
Functional block diagram in conjunction with Fig. 6 monitoring infusion terminal LCD screen, after installing the monitoring infusion device, energized, close a switch, at first show name of product on the LCD screen 3-3 of monitoring infusion terminal 3, all units, after the information such as version, stop and entered man machine interface in 5 seconds, two video windows in the LCD screen 3-3 left side, show infusion bottle video image and Perfusion drip funnel video image respectively, adjust infusion bottle monitoring probe 1 and dropping funnel monitoring probe 2, the feasible infusion bottle video image that will monitor and Perfusion drip funnel video image are positioned at the centre of display screen windows, liquid level is not higher than 3cm in the dropping funnel, it is high-visible that drop splashes into liquid level like this, is convenient to supervising device identification drop and splashes into the vibrations that liquid level takes place.The display screen upper right quarter shows transfusion real-time status information, comprise transfusion speed, transfusion speed too fast/slow/normal information with excessivelying, and the information that whether is near completion of infusing.
The display screen right lower quadrant is three function keys that realize man-machine interaction, presses " beginning " key, and this monitoring infusion device begins monitor procedure, and monitoring infusion terminal 3 begins to read infusion bottle video image and transfusion funnel video image; Press " stopping " key, monitoring infusion terminal 3 stops to read video information, stops image and handles, and stops the alarm of sound and light, does not upgrade screen, and screen rests on " stopping " key state before of pressing; When leaving sick bed midway, can press transfusion patient " stopping " key, open the clip of the second fixed support 2-3 at dropping funnel position, supervising device is separated with infusion set, leave sick bed, when continuing transfusion again, retightened infusion bottle and dropping funnel monitoring probe 2, pressed " beginning " key and then can restart to carry out monitoring infusion; Press " withdrawing from " key, monitoring infusion terminal program out of service.On and off switch and volume switch are equipped with in monitoring infusion terminal 3 bottoms, voice switch are closed to get final product when not needing phonic warning.
For example set: the fastest value V of transfusion speed
Max=120 droplets/minute, transfusion speed be worth V the most slowly
Min=20 droplets/minute, the liquid drop speed of detection was higher than 120 droplets/minute in lasting 5 seconds, sent the too fast alarm of transfusion speed; When the liquid drop speed that detects was lower than 20 droplets/minute in lasting 5 seconds, send transfusion speed and cross alarm slowly.When transfusion speed by normally being reduced to gradually below the low speed thresholding, meaning the transfusion is near completion.Can judge the R of liquid level vibrations according to the practical situation adjustment
LT, R
HTThreshold value and transfusion prestissimo and jogging speed.Adopt 320*240 resolution photographic head, set H
Min=1cm, R
LT=200, R
HT=1200, V
Min=20 droplets/minute, V
Max=120 droplets/minute, read picture and be spaced apart 200 milliseconds, when monitoring lucky 3 frames at interval of the frame number that meets scope, namely interval is 800 milliseconds, then calculating the transfusion real-time speed is 60000 milliseconds/800 milliseconds=75 droplets/minute.
This utility model adopts the non-intervention type method, monitors by the observation external video, and is noiseless to infusing; Link to each other with fluid delivery apparatus by fixed support, can withdraw at any time, solved patient infusion problem such as go to toilet midway; Between monitoring probe and infusion bottle and the dropping funnel ten centimeters distance is arranged, the artificial supervision of tradition is unaffected, can carry out simultaneously; The infusion set material is not had specific (special) requirements, and infusion bottle, transfusion bag all can be monitored; The LED lamp has been installed on this probe, and guaranteeing also has enough illuminations in night, but night on daytime equal operate as normal; The work of can networking is convenient to nurse's control station and is monitored a plurality of transfusion patients simultaneously, reduces labor intensity greatly.
