Description
Technical field
The present invention relates to the medical assistance instrument field, in particular, the invention relates to a kind of automatic infusion that collection measures, a speed is detected on one and help alarm device control method and device.
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; The warning that finishes of infusing when in the time of setting, not have the dropping liquid of detection; Thereby have only when transfusion and just can send the warning that finishes of infusing after flow from container, the time of leaving nurse's processing like this for does not have practicality very little.Also there is the surplus of infusing to calculate by the quantity accumulative total of dropping liquid, thereby reach the purpose of reporting to the police in advance, but find simple quantity accumulative total in actual the use by dropping liquid, can not accurately calculate the use amount of transfusion, the promptly simple amount of infusion and the actual bigger error of amount of infusion existence that goes out by the quantity cumulative calculation of dropping liquid causes or infuses to finish and not warning, perhaps sending transfusion and finishing when 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 spring detection foundation as the transfusion surplus, yet owing to deposit the difference that the utensil of transfusion has vial, plastic bag etc., and the fatigue deformation of spring influence, cause the detection of transfusion surplus and warning can not satisfy actual needs.Simultaneously the infusion alarm made of spring balance principle can not carry out simultaneously that transfusion speed is reported to the police and the transfusion that causes because of fortuitous event stops to report to the police.Unless two covering devices use simultaneously, but this has increased cost of equipment and nurse's workload again.
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 made up 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, have only under the normal condition 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 constitute loop I by the lead polyphone, and power supply and spring, armature, contact block and electric bell constitute loop II by the lead polyphone.Owing to adopt 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 transfusion of announcement finishes, and reaches to guarantee the transfusion purpose of safety.This alarm adopts probe to be inserted in the liquid in the infusion bottle, pollutes transfusion easily, 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 transfusion metering that exist in the prior art, have only after the transfusion in the infusion vessel has been flowed and to report to the police, perhaps the inaccurate shortcoming that can not satisfy instructions for use is measured in transfusion, provide a kind of can accurate measurement, carry out the transfusion speed detection alarm simultaneously and the automatic infusion of reporting to the police that finishes of accurately infusing in advance helps alarm device control method and device.
The technical solution adopted for the present invention to solve the technical problems is: the invention provides the control method that a kind of automatic infusion helps alarm device, the dropping liquid trace routine, the alert program that comprise boot program, transfusion, also comprise accounting procedure, accounting procedure comprises according to resulting liquid droping speed of dropping liquid trace routine and dropping liquid quantity, be provided with 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 the warning/early warning that finishes of infusing when the performance of transfusion reaches.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, promptly 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 the simple amount of infusion and the actual bigger reasons of error of amount of infusion existence that goes out by the quantity cumulative calculation of dropping liquid; 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 to actual detected to dropping liquid quantity revise, 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 the transfusion performance that adds up reaches the warning of setting or early warning and requires, warning or the early warning that just can infuse and finish since metering accurately, both can reserve pre-set time accurately to the nurse, can not cause waste again.
Further, accounting procedure is provided with between three metering zones, when liquid droping speed is district at a slow speed below 40 droplets/minute the time, when liquid droping speed 41---be the middling speed district in the time of between 80 droplets/minute, when liquid droping speed be to distinguish fast at 81 when above; Qu correction factor 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.Though get thin more between metering zone, the transfusion performance that calculates is accurate more, 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 bigger amount of calculation burden to central processing unit; Simultaneously by a large amount of actual observations and detection, 41 droplets/minute---80 droplets/minute liquid droping speed is modal liquid droping speed, and the mass change of every dropping liquid is not very big in this scope, therefore the dropping liquid quality with this liquid droping speed is a standard value, correction factor is 1, liquid droping speed is made as district at a slow speed in time below 40 droplets/minute, when liquid droping speed is made as quick district when above at 81 droplets/minute, and to district and the quick dropping liquid quality of distinguishing are revised at a slow speed, very approaching by the transfusion performance that such method calculates with actual transfusion performance, can satisfy the required precision of most of transfusion.
Further, accounting procedure is provided with between five metering zones, when liquid droping speed is speed district slowly below 20 droplets/minute the time, when liquid droping speed 21---in the time of between 40 droplets/minute at a slow speed the district, when liquid droping speed 41---be the middling speed district in the time of between 80 droplets/minute, 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 droplets/minute; Slowly the correction factor in speed district is 0.95-0.0.96, and Qu correction factor 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 correction factor in district fast is 1.04-1.05.When old people or child infused, transfusion speed may be below 20 droplets/minute; The youthful liquid droping speed that has equally can be more than 120 droplets/minute, so accounting procedure is divided into and can makes the calculating of further improving the transfusion performance between five metering zones, and its estimation for accuracy is higher under 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, i.e. 60/ Mean Time Between Replacement (second)=liquid droping speed (droplet/minute) by the Mean Time Between Replacement of these 5 dropping liquids; Correction factor between dropping liquid variable=5 of these 5 dropping liquids * 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 the accuracy of metering, 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 influence measuring accuracy, therefore take all factors into consideration from the amount of calculation and the memory footprint of measuring accuracy requirement, central processing unit, 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 shutdown automatically 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 to enter automatically 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 shutdown automatically of dropping liquid in 100 seconds, can avoid the power supply waste of 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 the time too weak point can make the nurse feel to feel it is pressed for time, the time is oversize to need after nurse operation is finished time of waiting for oversize, influences 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 takes place, all simultaneously parameter setting buttons lost efficacy, and had guaranteed after the nurse leaves, other personnel can not change parameter without authorization, improve safety.
As preferably, boot program comprises that at described parameter setting state the liquid droping speed higher limit is set, the liquid droping speed lower limit is set: begin the initial detected 5 dropping liquid Mean Time Between Replacements in back as liquid droping speed upper limit initial value, liquid droping speed lower limit initial value at described parameter setting state, i.e. 60/ initial detected 5 dropping liquid Mean Time Between Replacements (second)=liquid droping speed upper limit initial value, liquid droping speed lower limit initial value; Under the parameter setting state, when pressing higher limit setting button, higher limit droplet/minute circulates in display from described liquid droping speed upper limit initial value-200 automatically and shows, when pressing higher limit once more and setting button, the shown higher limit of display is exactly the liquid droping speed higher limit of setting; Under the parameter setting state, when pressing lower limit setting button, lower limit droplet/minute circulates in display from described liquid droping speed lower limit initial value-10 automatically and shows, when pressing lower limit once more and set button, the shown lower limit of display is exactly the liquid droping speed lower limit of setting; Under the parameter setting state, to be set at the benchmark liquid droping speed according to the last liquid droping speed that the dropping liquid trace routine obtains, all never be pressed when setting button in entire parameter set condition higher limit in period, system drips speed * 150 ± 10% with described benchmark automatically and is set at the liquid droping speed higher limit; All never be pressed when setting button at entire parameter set condition lower limit in period, system drips speed * 50 ± 5% with described benchmark automatically and is set at the liquid droping speed lower limit.Demonstration/the set point of liquid droping speed higher limit is arranged in the liquid droping speed upper limit initial value to 200 droplet/minute, the demonstration/set point of liquid droping speed lower limit is arranged in the liquid droping speed lower limit initial value to 10 droplet/minute, can increase nurse's work efficiency.Under the parameter setting state, the nurse also can only adjust liquid droping speed, system sets liquid droping speed higher limit, liquid droping speed lower limit according to the liquid droping speed that the nurse adjusts automatically, for most of adults by such establishing method set the liquid droping speed higher limit, the liquid droping speed lower limit all is safe, thereby reduce nurse's workload.
As preferably, when described benchmark drips speed * 150 ± 10% 〉=200 droplet/timesharing, boot program is set at 200 droplets/minute with the liquid droping speed higher limit; When described benchmark drips speed * 50 ± 5≤10 droplet/timesharing, boot program is set at 10 droplets/minute with the liquid droping speed lower limit.200 droplets/minute liquid droping speed is maximum liquid droping speed, surpassing this speed understands dangerous to the patient, and 10 droplets/minute liquid droping speed is minimum liquid droping speed, might therefore maximum liquid droping speed higher limit and minimum dropping liquid lower velocity limit value be set improve transfusion safety and equipment dependability because of the too approaching false alarm that produces of the judgement time of dropping liquid blanking time and dropping liquid termination warning less than this speed.
