Description
Technical field
This utility model relates to a kind of medical monitoring and automation field, is specifically related to a kind of infusion alarm.
Background technology
At present, venous transfusion is a kind of important route of administration in clinical treatment, has very important effect in the treatment.Patient, when infusing, needs nurse, to accompany and attend to or patient oneself often checks residual liquid quantity in infusion bottle, and change liquid as required or pull out transfusion needle.Because transfusion time is longer, patient or entourage neglect unavoidably, and can not flow sky by liquid in Timeliness coverage infusion bottle, cause vein blood back, cause unnecessary loss and misery, even threaten patient vitals.Therefore, the infusion alarm can automatically reminded when liquid will be totally lost just seems very necessary.
Though current existing infusion pump function ratio is comparatively comprehensive and precision is higher, equipment too expensive, be unfavorable for applying on a large scale; The existing infusion alarm structure utilizing photovoltaic principals to design is simple, easy to use, but easily because transfusion device pipeline tilts or bubble produces false alarm; The infusion alarm structure of existing employing spring scale repacking is simple, and cost is lower, but precision is too poor; Though the infusion alarm structure of existing employing pressure guidance is simple, precision is higher, there is the hidden danger of liquid contamination.
Utility model content
The purpose of this utility model is the deficiency existed for above infusion alarm, provide that a kind of cost is low, precision is high, volume is little, easy to use, reliability is high, be convenient to infusion alarm and the control method thereof of medical institutions' widespread adoption, improve nursing quality, reduce medical-risk.
For achieving the above object, this utility model takes following technical scheme;
A kind of infusion alarm, comprising annunciator panel, being fixed on annunciator panel top for the suspension ring that are connected with drip stand be connected to bottom annunciator panel for hanging the hook of transfusion bottle;
Described annunciator panel is provided with function selecting button, for selecting and showing the display screen of different size transfusion bottle and cancel alarm button; Annunciator panel is built-in with control warning system;
Described control warning system comprise with link up with signal that the pulling force sensor, the signal conditioning circuit receiving pulling force sensor monitor signal, the Received signal strength that are connected nurse one's health circuit for judge transfusion bottle mass change situation controller, to be connected the loudspeaker that carry out reporting to the police with controller and for providing the power supply of electric energy as whole control system;
Described function selecting button, display screen are all connected with controller with cancellation alarm button.
As further improvement of the utility model, described power acquisition AAA battery.
As further improvement of the utility model, described signal conditioning circuit mainly adopts the output signal of operational amplifier to pulling force sensor to nurse one's health, and is treated to and meets the stable simulation voltage signal that controller accepts scope.
As further improvement of the utility model, described controller adopts the single-chip microcomputer at least with a road AD passage and four road DI/DO passages.
As further improvement of the utility model, the line traffic control that described cancellation alarm button draws patient's straightforward manipulation by wire cancels alarm button.
A control method for infusion alarm, comprises the following steps:
Pulling force sensor Detection job when setting hook is non-loaded is M
0; According to actual transfusion bottle specification, select corresponding transfusion bottle model by function selecting button, controller sets the alarm threshold value M judging transfusion bottle mass change situation automatically
1;
Judge that controller receives pulling force sensor and monitors quality on hook at time T
1inside whether be greater than M
0; If not, be then judged as without transfusion bottle, controller controls whole system automatic shutdown; If so, be then judged as that transfusion bottle is infused;
In infusion process, pulling force sensor carries out Real-Time Monitoring to transfusion bottle quality, and by signal conditioning circuit by signal transmission to controller, controller is to current measurement value and setting alarm threshold value M
1compare in real time, if meet alert if, controller drives loudspeaker to report to the police; Alert if refers to:
The signal value received when controller is greater than setting alarm threshold value M
1time, and signal value T continuous time
3in not change, or continuous time T
3interior reduction is less than or equal to mass M
2time, report to the police;
When in duration T
2interior real-time measurement values is less than or equal to setting alarm threshold value M
1time, controller controls loudspeaker and reports to the police;
Cancel controller after reporting to the police again to compare in real time current measurement value and setting alarm threshold value.
Further, T
1be 5 minutes, T
2be 5 seconds, T
3be 2 minutes, M
2it is 4 grams.
Further, M

1quality be M
0+ empty transfusion bottle quality+empty transfusion device quality+25 grams quality of remaining liq in transfusion device and transfusion bottle (25 grams be).
Further, described cancellation alarming step is cancelled for adopting operation to cancel alarm button cancellation or adopting line traffic control to cancel alarm button.
Relative to prior art, the beneficial effects of the utility model are:
Infusion alarm of the present utility model is for infusion alarming problem, adopt pulling force sensor and control warning system, utilizing automatic control mode to achieve automatization and the intellectuality of infusion alarming, relative to traditional alarm technique, there is higher reliability, and cost is low, easy to use; This utility model is because adopting Electrical Control Technology, and decrease complicated mechanism design, not only alleviate alarm quality, reduce alarm volume, the more important thing is easy to operate, degree of accuracy improves greatly.And cancellation alarm button is set, cancels warning in time.
Pulling force sensor is directly connected with the hook of suspension transfusion bottle, for Real-Time Monitoring transfusion bottle quality, improves more than 10 times relative to mechanical type infusion alarm precision of weighing.
Further, line traffic control is cancelled arranging of alarm button and is facilitated patient oneself to operate cancellation warning, convenient and practical.
The automatic control technology that control method of the present utility model adopts, report to the police when will can not only drip off liquid, and can cause transfusion slowly or stagnate and report to the police to being accidentally pressed onto because of patient or folding to transfusion device pipeline, think that liquid is totally lost when the current measurement value of transfusion bottle quality is less than or equal to setting alarm threshold value; When transfusion bottle quality thinks when reduction is less than or equal to 4 grams in continuous 2 minutes that transfusion device pipeline is pressed onto or opisthotonos accidentally.Controller, for judging the situation of change of transfusion bottle quality, if meet alert if, drives loudspeaker to report to the police.At lower cost, achieve higher intellectuality, avoid because of not by the potential safety hazard brought of the timely medication of regulation.
Further, this utility model adopts automatic control system can Real-Time Monitoring self duty, when there is no transfusion bottle under continuous 5 minutes monitor hook, and can automatic shutdown.When not increasing nursing staff's workload, reach energy-conservation object.
Further, infusion alarm of the present utility model and control system cost is low, precision is high, volume is little, simple to operate, reliability is high, be convenient to medical institutions' widespread adoption, for the research of Subsequent infusions alarm and control system provides a kind of new thinking, there is very important realistic meaning and researching value.
