The specific embodiment
Provide preferred embodiment of the present invention below, in order to architectural feature of the present invention, technical performance and functional characteristics to be described.
At first please refer to Fig. 1, Fig. 1 is the general system set-up sketch map of one embodiment of the present of invention.One embodiment of the present of invention comprise a monitoring host computer and several slaves, and main frame is placed on Control Room, and slave is placed on by the transfusion medicine bottle.Pass through the radio communication exchange message between main frame and the slave, the kind of energy display abnormality situation on the slave, and main frame can the display abnormality situation be to occur on which platform slave.
Please refer to Fig. 2 and Fig. 3, they are respectively the main frame of one embodiment of the present of invention and the theory diagram of slave.The main frame that is placed on Control Room comprises single-chip microcomputer, radio receiving transmitting module, LCD display and parts such as light, buzzer.Wherein radio receiving transmitting module is subjected to Single-chip Controlling poll slave, and single-chip microcomputer is handled information that radio receiving transmitting module receives and it is shown on attention display.Slave then is made up of single-chip microcomputer, transfusion drip speed pick off, radio receiving transmitting module and LCD display etc., pick off monitoring transfusion situation and send it to single-chip microcomputer wherein, the data that single-chip microcomputer can be set warning trigger condition and calculating sensor acquisition judge whether to report to the police, and radio receiving transmitting module is subjected to Single-chip Controlling to send information to main frame.
Main frame and slave all use AVR single-chip microcomputer (single-chip microcomputer of other band analog-digital converters all can directly use, and does not add upconverter with the single-chip microcomputer of analog-digital converter and also can use) as the control core.Radio communication adopts general module.Attention display is a LCD display, the slave coding and the warning kind of its display alarm.Pick off comprises droplet a speed sensors and a detecting liquid level pick off, and dripping a speed sensors is one group of correlation type pick off, and correlation type pick off is the open tube form and is enclosed within dripping on the fast viewing section of tube for transfusion; Be placed on the outer correlation type optical sensor of transfusion drip tube section and can obtain stable numerical value, drip through out-of-date, reflection of light and refraction action be made the sensor reading change there not being medicine to drip, measure medicine liquid droplet speed through the computing of single-chip microcomputer again because medicine drips as medicine through out-of-date.The detecting liquid level pick off is a reflection-type infrared sensor that is attached on the liquid medicine bottle wall.
Transfusion drip speed should remain in certain scope, and it is too fast that a speed is unusually particularly dripped speed, and the harm that brings to patient is very big.Present embodiment uses the AVR single-chip microcomputer as the control core, connects the speed of dripping of monitoring medicinal liquid through the pick off of repacking.Correlation type infrared light transducer[sensor pick off can be distinguished the current water droplet process that has or not, and counts the water droplet number that flows through in the unit interval then, can obtain the speed of dripping of medicinal liquid.When not having water droplet through out-of-date, the infrared light that infrared transmitting tube sends is radiated on the infrared receiving tube, and pick off can obtain stable numerical value.Through out-of-date, because water droplet is to infrared reflection of light and refraction action, sensor reading changes immediately as water droplet.Each medicinal liquid all has suitable transfusion speed, all be to drip quantity as transfusion speed unit in hospital with the per minute medicine, and different patients has different requirements to transfusion speed, after determining good tolerance, the lower limit and the upper limit of transfusion speed have also just been determined, prescribe a time limit less than lower limit or greater than last when transfusion speed, system will send alarm signal.
Use is attached to the reflection-type infrared sensor on the liquid medicine bottle wall, and the infrared light that reflects by emission infrared light and reception can be surveyed the position of liquid level in the liquid medicine bottle.The liquid medicine liquid level obtains different readings from the reflexive pick off during respectively above and below pick off.When liquid level was higher than pick off, because the infrared external reflection that obtains is less, sensor reading was bigger; When liquid level was lower than pick off, because the infrared external reflection that obtains is more, sensor reading was less.Utilize the reading difference of pick off, just can judge liquid level position and whether be lower than pick off.If pick off is attached to the correct position of liquid medicine bottle wall, just can obtain information by it, whether the medicinal liquid of judging in the liquid medicine bottle will drip to the greatest extent.
For the reliability that improves system must be eliminated the influence that ambient light is surveyed drop.Under indoor fluorescent lamp lighting condition, if there is not the water droplet process, the reading that obtains from infrared sensor is about 50; Water droplet is through out-of-date, and the reading that obtains from pick off is about 75.When the ambient light no change, can utilize the reading of pick off to judge and have or not the water droplet process.In different occasions, because the influence of surround lighting, the reading that obtains from infrared sensor is different, and data see the following form.
| Test environment | Reading (no water droplet) | Reading (water droplet process) |
| Indoor fluorescent lamp lighting | ????50 | ??75 |
| Indoor daytime is near the window | ????46 | ??69 |
| Total darkness environment | ????61 | ??85 |
| Daytime is outdoor | ????38 | ??63 |
From above data relatively as can be seen owing to comprise infrared composition in the surround lighting, in bright and dark environment, pick off also can receive the infrared light in the environment except receiving the infrared light that infrared transmitting tube sends.Having or not the water droplet process if directly use the reading of pick off to judge, is not all right.Owing to there is water droplet big by about 15 through the out of date sensor reading sensor reading during than no water droplet, so as long as measure earlier no water droplet through the time pick off reading, at this moment have water droplet to pass through if acquisition than the reading of this reading big 15, just can be judged.
If not by the transmitting tube and the receiving tube center of pick off, will cause and survey error when drop is descending in addition.The present invention has designed the sensor construction of pipe opening form and has obtained effect preferably, tube for transfusion rock and influence that ambient light is surveyed drop all is reduced to bottom line.
Mode with radio communication between monitoring infusion point and Control Room is carried out information exchange.Main frame can be inquired each slave successively.Slave is waited for the inquiry of main frame, in case receive inquiry, just can answer main frame " normally " or " unusually ".Main frame just can show the information of receiving.Frequency of utilization is that the wireless communication module of 315 megahertzes carries out wireless telecommunications between main frame and the slave.Use " poll " to be because main frame and each slave use is same frequency, yet emission same frequency electric wave can the phase mutual interference in the process of communication, uses the mode of " poll " just to can solve this problem.
In the process of practical application, in a single day slave detects abnormal conditions (liquid level is low excessively, medicinal liquid to drip speed too fast or slow excessively), and it just can send the main frame of " unusually " information to Control Room when accepting " poll ".In a single day main frame receives this information, the sound that just can give a warning, and on liquid crystal display screen, show the numbering of slave.Slave sends " unusually " information always, up to the nurse reach the spot handle after, slave just recovers to send " normally " information.
According to top details introduction, Fig. 4, Fig. 5 have disclosed the complete workflow of main frame and slave.At first system is carried out initialization during host work, begin then slave is carried out poll and accepts its warning message, main frame is delivered to warning message and is continued slave again after its alarm device shows and carry out poll.Slave is at first measured ambient light after initialization, in order to of the influence of place to go ambient light to measuring, with that the drop flow velocity is measured, tolerance limit according to the data of measuring gained and input in advance in single-chip microcomputer judges whether the needs warning, if flow velocity normally then continue return measurement, if undesired then start self alarm device,, wait for the inquiry of main frame simultaneously as LCD and buzzer warning.After receiving the inquiry instruction of main frame, warning message is passed to host waits handle,, solve until problem if main frame not have inquiry or nobody to come to handle then continues the alarm device of use self in this process.The process that liquid level is reported to the police just repeats no more also similarly here.
Above introduce, it only is preferred embodiment of the present invention, can not limit scope of the invention process with this, it is the variation that is equal to that the those skilled in the art in the present technique field are done according to the present invention, and those skilled in that art improvement, the variation known, all should still belong to the scope that patent of the present invention contains.
