Wherein M is the transfusion bag capacity, and unit is ml; N is the current dropping liquid number that dripped; V is current liquid droping speed, unit drips/minute; A is the coefficient that drips of transfusion bag, and unit is that ml/ drips.
When remaining transfusion time less than a predetermined threshold, said radio-frequency module sends an alarm signal to control centre.
Another aspect of the present invention provides a kind of method of using infusion monitor to carry out monitoring infusion, and said operational approach may further comprise the steps:
Description of drawings
Fig. 1 is that application system of the present invention constitutes;
Fig. 2 is the formation block diagram of infusion monitor of the present invention;
Fig. 3 is the operational flowchart of infusion monitor of the present invention.
The specific embodiment
Fig. 1 has shown the formation of device of the present invention.Transfusion display system remaining time of the present invention is made up of a plurality of infusion monitors 11 and control centre 12.
Fig. 2 has shown the formation of infusion monitor 11, and it is by radio-frequency module 101, CMOS photographic head 102, and microprocessor 103, supply unit 104, LCDs 105 and memorizer 106 constitute.Infusion monitor 11 is fixed on the drip stand.Exchange or dc source if having near the drip stand, then supply unit 104 can be made up of AC-dc converter, the civil power conversion of 220V is exported the electronic system of the voltage supply infusion monitor 11 of 5v.If there is not power supply near the drip stand, then supply unit 204 is made up of a high-effect battery and DC to DC converter, and output dc voltage is supplied with the electronic system of infusion monitor 11.
The CMOS photographic head 102 of infusion monitor is designed to be attached on the tube for transfusion, and the camera lens of its photographic head is over against the position of droplets fall.Photographic head is taken the picture of droplets fall continuously, and video signal is delivered to microprocessor 103 handle.Memorizer 106 is coupled in microprocessor 103, is used to store program intermediate data and frame data etc.Typically; Memorizer can be DDR2 SDRAM chip granule; Microprocessor can be SOC (the system on chip) chip based on the ARM kernel; The quantity of the drop in the S3C6410. microprocessor 103 of the Samsung identification per second video signals for example, and go out current transfusion speed according to the mean value calculation in front and back several seconds.The liquid droping speed recognizer of microprocessor 103 can be accomplished by typical image recognition algorithm.For example, relatively the difference of front and back 2 two field pictures is divided into frame that moving object is arranged and the frame that does not have moving object with frame of video; And twice have the meansigma methods of the interval between the moving object frame crowd; Be exactly twice interval between the droplets fall,, then can calculate transfusion speed according to these data.Illustrate, for example, the frame per second of CMOS photographic head was 30 frame/seconds; Stroke according to droplets fall can calculate; Drop drops to the water surface needs about 0.2 second time, if the speed of drop drippage is 1 droplet/second, so in the picture of per second production; Have 6 frames can photograph the picture of motion water droplet approximately, and other 24 frames are immobilized background frame.Microprocessor is according to 24+6=30 frame at interval between the picture that occurs the motion water droplet for twice, and the speed that can calculate transfusion is 1 droplet/second.
Clinical transfusion device commonly used drips that coefficient has 1/10,1/15,1/20ml/ drips three kinds of models, drips coefficient according to transfusion device and can carry out following formula reasoning:
Per hour the milliliter number (ml/h) of input=(drip/min) x60 (min/h) x drips coefficient (ml/ drips) therefore, is 1/10,1/15 when dripping a coefficient, when 1/20ml/ drips, the above-mentioned formula of substitution can draw respectively:
(1) dripping coefficient is that 1/10ml/ drips, then: the milliliter number of input=(drip the x6 of number/min) per hour.
(2) dripping coefficient is that 1/15ml/ drips, then: the milliliter number of input=(drip the x4 of number/min) per hour.
(3) dripping coefficient is that 1/20ml/ drips, then: the milliliter number of input=(drip the x3 of number/min) per hour.
Its coefficient of each transfusion device is changeless; Therefore; Utilize above-mentioned 3 formula, the number of drops of the each second that calculates according to microprocessor 103 can calculate the milliliter number of per hour input; If the volume of known transfusion bag or infusion bottle then can calculate the time that the transfusion completion needs.And,, then can calculate a bit temporal arbitrarily residue transfusion deadline according to number of drops of having dripped and present liquid droping speed.
For example, transfusion bag is M ml, and current drops is N, current liquid droping speed be V drip/minute, the coefficient that drips of transfusion device drips for A ml/, then remains transfusion time and does
T＝(M-N*A)/(V*A)
Wherein the unit of T is minute.
Radio-frequency module 101 is for having the short-range wireless transceiver of radio transmission-receiving function.Typically, radio-frequency module 101 can be for meeting the wireless sensor network module of zigbee standard.Radio-frequency module 101 carries out wireless data communication with control centre 12.When microprocessor calculated the current residual liquid measure less than a given thresholding, for example 50ml then sent an alarm signal, is sent to control centre 12 through radio-frequency module 101.Alarm signal is received by control centre, produces certain sound and light alarm information, offers nurse on duty, reminds its processing of infusing.
Fig. 3 demonstrates the operating procedure that shows the monitoring infusion device of remaining time of the present invention
In the step 1, the nurse hangs over transfusion bag on the drip stand, through the action button of infusion monitor 11, opens the power supply of infusion monitor;
Embodiments of the invention have more than been described; But, should be appreciated that, obviously be easy to the present invention is made like this and such modification for those skilled in the art; Promptly do not departing from the present invention spirit and setting up under the prerequisite of claims scope and can make various variations, remodeling and revising.
