Description of drawings
Fig. 1 is the device one example structure sketch map of the automatic test point dropping liquid of the present invention surplus;
Fig. 2 is the method one embodiment schematic flow sheet of the automatic test point dropping liquid of the present invention surplus.
In order to make technical scheme of the present invention clearer, clear, be described in further detail below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, one embodiment of the invention proposes a kind of device of automatic test point dropping liquid surplus, comprise: be positioned at RFID (the Radio Frequency Identification on the drop bottle liquid level, RF identification) buoy 2, be arranged on outer perceptron 1 of a drop bottle and the alarm receiving system 3 that is connected with perceptron 1, perceptron 1 is used for the distance between detection regularly and the RFID buoy 2, when distance during, send alarms to alarm receiving system 3 less than reservation threshold.
Particularly, perceptron 1 comprises RFID detection module 11, singlechip chip 12, alarm sending module 13, signal indicating module 14 and battery 15 in the present embodiment, wherein:
Distance when can set point drop bottle mid point dropping liquid being about to exhaust between RFID buoy 2 and the perceptron 1 is as reservation threshold, when detecting distance between perceptron 1 and the RFID buoy 2 less than reservation threshold, RFID detection module 11 sends warning signals by singlechip chip 12 to alarm sending module 13; After alarm sending module 13 receives warning signal, send alarm to alarm receiving system 3,3 notices of alarm receiving system dependent observation personnel in time deal with, in case malpractice occurs, saves drop observation personnel's time simultaneously.
In other embodiments, also can on perceptron 1, power interface be set, perceptron 1 is connected with external power source, can make perceptron 1 operate as normal equally.
Alarm receiving system 3 can be PC (Personal Computer in the present embodiment, personal computer) etc., itself and perceptron 1 can be wireless, and also can be wired, and need verify in use can proper communication between perceptron 1 and the alarm receiving system 3.
Alarm receiving system 3 can be positioned over associated care personnel's office or other have the place of special messenger's observation, the observation personnel can observe the amount of liquid situation of grasping the some dropping liquid in a plurality of somes drop bottles simultaneously by alarm receiving system 3, in case receive the alarm of respective point drop bottle, then this drop bottle is in time handled, thus, avoided in the existing drop detection method each some drop bottle all need observe personnel observe the drawback that causes wasting the observation personnel time always.
Perceptron 1 is arranged on outside the bottleneck of a drop bottle in the present embodiment, in other embodiments, perceptron 1 also can be arranged on other outer places of a drop bottle, wherein, the outer embodiment of bottleneck that perceptron 1 is arranged on a drop bottle is a best mode, and the RFID detection module 11 in the perceptron 1 can read the radiofrequency signal in the RFID buoy 2 preferably.
In use, after fluid infusion work begins, perceptron 1 detects once distance between this perceptron 1 and the RFID buoy 2 every one period set time (such as 1s), if this distance is less than reservation threshold N, then notify alarm sending module 13 to send alarm to alarm receiving system 3, if this distance still greater than reservation threshold N, then need repeat top step up to detect distance between RFID buoy 2 and the perceptron 1 less than N till.
Because perceptron 1 places intravenousdrip bottle mouth in plug-in mode in the present embodiment, therefore a perceptron 1 can repeatedly use, and can select battery 15 kinds to satisfy nonexpondable needs as required.
As shown in Figure 2, one embodiment of the invention also proposes a kind of method of automatic test point dropping liquid surplus, comprising:
Step S101, perceptron regularly detect and put the distance between the RFID buoy in the drop bottle;
Present embodiment makes full use of radiofrequency signal interaction concept between RFID card reader and the RFID label, perceptron is equivalent to the RFID card reader in the present embodiment, the RFID buoy is equivalent to the RFID label, read radiofrequency signal in the RFID buoy by perceptron, according to the distance between the RFID buoy in this radio-frequency signal detection perceptron and the some drop bottle.Determine the surplus of some dropping liquids by detecting the distance of surveying between perceptron and the RFID buoy.Along with a minimizing gradually of drop bottle mid point dropping liquid, the radiofrequency signal that the RFID detection module reads in the RFID buoy constantly changes, and such as grow gradually, can be converted into the judgement to the distance between perceptron and the RFID buoy according to the variation of above-mentioned radiofrequency signal.
Whether step S102, judging distance be less than reservation threshold, if then enter step S103; Otherwise, return step S101;
Step S103 sends alarm to the alarm receiving system.
Distance when can set point drop bottle mid point dropping liquid being about to exhaust between RFID buoy and the perceptron is as reservation threshold, when detecting distance between perceptron and the RFID buoy less than reservation threshold, the RFID detection module sends warning signal by singlechip chip to the alarm sending module; After the alarm sending module receives warning signal, send alarm to the alarm receiving system, the alarm receiving system then notifies the dependent observation personnel in time to deal with, in case malpractice occurs, saves drop observation personnel's time simultaneously.
The alarm receiving system can be PC etc. in the present embodiment, itself and perceptron communicate by wireless connections, also can be wired in other embodiments, no matter which kind of mode connects, and need verify in use can proper communication between perceptron and the alarm receiving system.
The alarm receiving system can be positioned over associated care personnel's office or other have the place of special messenger's observation, the observation personnel can observe the amount of liquid situation of grasping the some dropping liquid in a plurality of somes drop bottles simultaneously by the alarm receiving system, in case receive the alarm of respective point drop bottle, then this drop bottle is in time handled, thus, avoided in the existing drop detection method each some drop bottle all need observe personnel observe the drawback that causes wasting the observation personnel time always.
The device and method of the automatic test point dropping liquid of embodiment of the invention surplus, detect the RFID buoy on the liquid level and the distance between this perceptron in the drop bottle by being arranged on the outer perceptron of intravenousdrip bottle mouth, when above-mentioned distance less than reservation threshold, be that surplus that perceptron detects the some dropping liquid in the drop bottle gives the alarm when being about to exhaust, to remind related personnel's malpractice of in time taking measures to avoid taking place, do not need the special messenger looking on measuring point dropping liquid surplus always, for nursery work brings great convenience, significantly reduced nursing staff's working time, and the present invention is easy to use, simple to operate, popularize easily.
The above only is the preferred embodiments of the present invention; be not so limit claim of the present invention; every equivalent structure or flow process conversion that utilizes description of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present invention.
