Description
Technical field
The present invention relates to the medical assistance instrument field, in particular, the invention relates to the collection metering, drip a kind of automatic infusion alarm device control method and device that speed is detected on one.
Background technology
At present, most of infusion alarms adopt the infuse dropping liquid of dropping liquid of infrared detection devices to detect, and carry out dropping liquid during greater than setting value when the speed of dropping liquid and cross and report to the police; Carrying out dropping liquid during less than setting value when the speed of dropping liquid crosses slowly and reports to the police; Carry out the infusion-completed warning during dropping liquid that within the time of setting, not have to detect; Thereby only have and after transfusion has been flowed from container, just can send the infusion-completed warning, leave like this time of nurse's processing for very little, do not have practicality.Also there is the surplus of infusing by the quantity accumulative total of dropping liquid to calculate, thereby reach the purpose of reporting to the police in advance, but find simple quantity accumulative total by dropping liquid in actual the use, can not accurately calculate the use amount of transfusion, namely merely there is larger error in the amount of infusion that goes out of the quantity cumulative calculation by dropping liquid with actual amount of infusion, causes or infuses complete and do not report to the police, when perhaps sending infusion-completed and reporting to the police, reality also has more surplus, causes waste.Because the inaccurate of metering limited infusion alarm promoting the use of in healthcare structure.
Now also there are some infusion alarms to adopt the principle of spring balance, with the tensile elongation of the spring detection foundation as the transfusion surplus, yet owing to depositing the difference that the utensil of transfusion has vial, plastic bag etc., and the fatigue deformation of spring impact, cause the detection of transfusion surplus and warning can not satisfy actual needs.The infusion alarm made of the spring balance principle transfusion stop alarm that can not carry out simultaneously that transfusion speed is reported to the police and cause because of fortuitous event simultaneously.Unless two covering devices use simultaneously, but this has increased again cost of equipment and nurse's workload.
Patent Office of the People's Republic of China discloses a CN101112629A document on January 30th, 2008, name is called infusion alarm, this infusion alarm is comprised of photoelectric probe, inductive probe, control unit, audible alarm unit and flashing light alarm unit, utilize photoelectric probe and inductive probe to monitor for the liquid in infusion vessel and the transfusion viewer, detecting liquid is totally lost, is about to be totally lost or accident when stopping, by warnings of sounding of control unit control sound alarm unit, control the warning of flashing of flashing light alarm unit by control unit.This infusion alarm adopts photoelectric probe to detect dropping liquid, only have under normal circumstances when dropping liquid has flowed from container and could report to the police, thereby the processing time of leaving the nurse for very little, do not have practicality.
Patent Office of the People's Republic of China discloses a CN101584891A document on November 25th, 2009, name is called infusion alarm, this alarm comprises power supply, probe, electric magnet, spring, armature, contact block and electric bell, power supply and probe, electric magnet consist of loop I by the wire series winding, and power supply and spring, armature, contact block and electric bell consist of loop II by the wire series winding.Owing to adopting said structure, insert in the liquid of infusion bottle so will pop one's head in when using, loop I connects, and the electric current that electric magnet produces is removed the armature among the II of loop from contact block, loop II is disconnected, when in the infusion bottle there be not liquid, loop I disconnects, and the armature among the II of loop is connected with contact block under the effect of spring, loop II connects, electric bell sounds the alarm, and patient's infusion-completed of announcement reaches the purpose that guarantees infusion safety.This alarm adopts probe to be inserted in the liquid in the infusion bottle, easily pollutes transfusion, is can not be by medical institutions and patient's acceptable, thereby does not also have practicality.
Summary of the invention
The present invention can not carry out simultaneously for solving the transfusion speed and the infusion measurement that exist in the prior art, only have after the transfusion in the infusion vessel has been flowed and to report to the police, the perhaps inaccurate shortcoming that can not satisfy instructions for use of infusion measurement, the accurate measurement of a kind of energy is provided, has carried out simultaneously the transfusion speed detection alarm and accurately carry out in advance automatic infusion alarm device control method and the device that infusion-completed is reported to the police.
The technical solution adopted for the present invention to solve the technical problems is: the control method that the invention provides a kind of automatic infusion alarm device, the dropping liquid trace routine, the alert program that comprise boot program, transfusion, also comprise accounting procedure, accounting procedure comprises according to the resulting liquid droping speed of dropping liquid trace routine and dropping liquid quantity, arrange between some metering zones in the accounting procedure by the dropping liquid that do not coexist of liquid droping speed, between each metering zone, dropping liquid quantity be multiply by different correction factors, obtain the stoichiometric number value of dropping liquid; The performance estimation that the stoichiometric number value of dropping liquid is added up and obtains infusing is reported to the police when requiring when the performance of transfusion reaches, and carries out infusion-completed warning/early warning.The dropping liquid trace routine of transfusion is now ripe, mainly detects the drippage blanking time of dropping liquid by infrared detection device, thereby obtains dropping liquid quantity and calculate liquid droping speed; By a large amount of experiments, the quality of finding every dropping liquid is relevant with the blanking time of dropping liquid, namely when difference blanking time of dropping liquid be liquid droping speed not simultaneously, the quality of every dropping liquid is different, and this is to cause merely amount of infusion that the quantity cumulative calculation by dropping liquid goes out and actual amount of infusion to have the reason of larger error; Accounting procedure of the present invention is that length difference blanking time of dropping liquid is divided into the calculating of dropping liquid between some metering zones according to the velocity magnitude of dropping liquid, in between each metering zone the actual dropping liquid quantity that detects is revised, thereby obtain a dropping liquid stoichiometric number value; The stoichiometric number value of dropping liquid added up just can obtain the transfusion performance that conforms to actual amount of infusion; When cumulative transfusion performance reaches the warning of setting or early warning and requires, just can carry out warning or the early warning of infusion-completed, because metering is accurate, both can reserve accurately pre-set time to the nurse, can not cause waste again.
Further, accounting procedure is provided with between three metering zones, when liquid droping speed 40/be district at a slow speed when minute following, when liquid droping speed 41---be the middling speed district in the time of between 80/minutes, when liquid droping speed is quick the district at 81 when above; The correction factor in district is 0.965 at a slow speed---0.975, and the correction factor in middling speed district is 1, the correction factor in district is 1.025 fast---1.035.Although get thinner between metering zone, the transfusion performance that calculates is more accurate, but the actual liquid droping speed of considering transfusion is limited in scope, and the nurse is to the actual needs of warning lead precision, the calculating of metering is divided into the requirement that can satisfy most of actual use between three metering zones, and also can cause larger amount of calculation burden to central processing unit; Simultaneously by a large amount of actual observations and detection, 41/minutes---80/minutes liquid droping speed is modal liquid droping speed, and the mass change of every dropping liquid is not very large in this scope, therefore take the dropping liquid quality of this liquid droping speed as standard value, correction factor is 1, liquid droping speed 40/be made as at a slow speed when minute following and distinguish, when liquid droping speed 81/be made as quick district when minute above, and to district and the quick dropping liquid quality of distinguishing are revised at a slow speed, very approaching with actual transfusion performance by the transfusion performance that such method calculates, can satisfy the required precision of most of transfusion.
Further, accounting procedure is provided with between five metering zones, when liquid droping speed 20/be fast district the slowly when minute following, when liquid droping speed 21---in the time of between 40/minutes for distinguishing at a slow speed, when liquid droping speed 41---80/minute between the time be the middling speed district, when liquid droping speed 81---be quick district in the time of between 120, when liquid droping speed be to distinguish fast soon when above at 121/minutes; Slowly the correction factor in speed district is 0.95-0.0.96, and the correction factor in district is 0.965-0.975 at a slow speed, and the correction factor in middling speed district is 1, and the correction factor in district is 1.025-1.035 fast, and the fast fast correction factor in district is 1.04-1.05.When old people or child infused, transfusion speed may be below 20/minutes; The youthful liquid droping speed that has equally can be more than 120/minutes, so accounting procedure is divided into and can makes the calculating of further improving the transfusion performance between five metering zones, and the precision of its estimation is higher in the slow especially or express situation of liquid droping speed.
As preferably, per 5 dropping liquids of accounting procedure calculate a liquid droping speed, calculate the liquid droping speed of these 5 dropping liquids by the Mean Time Between Replacement of these 5 dropping liquids, i.e. 60/ Mean Time Between Replacement (second)=liquid droping speed (dripping/divide); Correction factor between the dropping liquid variable of these 5 dropping liquids=5 * this liquid droping speed place metering zone.Liquid droping speed of per 5 dropping liquids calculating can reduce the workload of central processing unit, when changing, liquid droping speed can in time measure adjustment simultaneously, guarantee measurement accuracy, certainly it once is not unique that per 5 dropping liquids calculate, dripping to per 20 calculating from per 1 once all is fine, but the oversize one side of interlude can increase the burden of memorizer and affect measuring accuracy, therefore amount of calculation and the memory footprint from measuring accuracy requirement, central processing unit considers, and per 5 calculating once are more rational.
As preferably, boot program comprises: control model is divided into holding state, parameter setting state, state on duty; To detect dropping liquid to trace routine be holding state from pressing the start button, if trace routine does not detect one after another drop of liquid, then automatic shutdown in 100 seconds from pressing behind the start button; Be the parameter setting state in trace routine detects behind first dropping liquid one minute, when the parameter setting state, alert program is not moved; The parameter setting state finishes automatically to enter state on duty, and in status alert program start operation on duty, the parameter setting button lost efficacy.When holding state, the dropping liquid trace routine starts, and carries out dropping liquid and detects, and does not detect then automatic shutdown of dropping liquid in 100 seconds, can avoid the waste of power supply electric energy; After detecting dropping liquid, enter the parameter setting state, the nurse can carry out the dropping liquid adjustment and can not report to the police under this state, and can carry out parameter setting, and certain one minute parameter setting time is not unique, and this time is fixed on 0.5---all be fine in 3 minutes; But too short meeting of time makes the nurse feel to feel it is pressed for time, and the time is oversize to need after can making again nurse operation complete time of waiting for oversize, affects nurse job efficient; Automatically enter state on duty after the parameter setting state finishes, under this state, alert program is started working, will send warning if alert event occurs, all parameter setting buttons lost efficacy simultaneously, had guaranteed after the nurse leaves, other personnel can not change parameter without authorization, improve safety.
