Description
Technical field
this utility model relates to a kind of design field of medical apparatus and instruments, especially a kind of drop flow velocity automatic speed governor.
Background technology
along with the development of biotechnology, new medicine constantly occurs, in the process of disease therapy, adopts dead point infusion method more and more general.Different medicinal liquid all has its different the best to drip fast requirement.Drip speed too fast, cross all can affect the treatment slowly, the amount of infusion of medical medicinal liquid and the accurate control of transfusion speed have reached better therapeutic effect.At present, in clinical transfusion process, the transfusion speed control and management method that nursing staff adopts " while see wrist-watch second hand; read to drip number while look into ", be about 10-15s by nurse's artificial counting, be then converted into 1 minute drip and count, obviously this transfusion dripping speed by perusal counting is difficult to accurate measurement control, nursing staff is for regulating to get up to waste time and energy during patient infusion simultaneously, inefficiency.Simultaneously patient or family members nursing staff not in case also often oneself rearrange liquids drip speed.Still call out nursing staff by patient oneself or family members when on the other hand transfusion terminates or to change bottle change dressings or pull out pin, very easily cause and ignore and occur danger.In infusion process, accidentalia causes having bubble to occur in liquid-transport pipe-line, more easily causes the even dangerous appearance of transfusion part edema occurs.The nonstandard fast malpractice that various factors causes occurs again and again, and even lethal case happens occasionally.The life security of patient can not be guaranteed, and medical tangle is difficult to avoid.Infusion pump on Medical Device Market can address this problem preferably, but the every only unit up to ten thousand of infusion pump, domestic also at several thousand yuan, berth is opened by general three grades of first-class above hospitals at least 20-80, hundreds of thousands unit need be invested, unit even up to a million, even if profitable hospital is also difficult to bear.The reform of follower community hospital, on the basis not changing ripe tubing sets, develops portable installation technically, drop automatic speed governor that portable uses is urgent and practicality.Investigate after deliberation, the liquid dropping speed measuring and monitoring device that current home and abroad uses mostly is overall Integrated system. and be a burden for hospital care department like this, this is the increase of seeing a doctor cost concerning consumer.In addition, the research and development of domestic present liquid dropping speed measuring and monitoring device, keep a foothold in warning more, the up-down mode of speed adjustment transfusion bottle, the physical size of system is huge, does not consider portable interface, lacks speed adjustment automatization and realizes and locking, therefore, the research of this project will fill up a blank in current medical intravenous drip practical application market.
Utility model content
for the problems referred to above, this utility model aims to provide a kind of drop flow velocity automatic speed governor.
for realizing this technical purpose, scheme of the present utility model is: a kind of drop flow velocity automatic speed governor, comprise funnel, flow regulator, cylindrical cam groove, slide bar, supporting seat, tiltedly carve groove, the column indenter indentation, tube for transfusion, sensor installation measuring circuit on described funnel, measure liquid droping speed, again measuring-signal is transferred to transfusion device speed governor portion, realizes flow velocity by single-chip microcomputer and micromachine and automatically regulate according to the standard flow rate of setting and lock.Reflection infrared sensor is directly installed on Dropping funnel by clamping structure, flow regulator is transformed into the automatic flow actuator tiltedly being carved groove rotation by minitype motor driving cylinder, single-chip microcomputer and signal processing thereof and transmission circuit are arranged on automatic regulator, and to be connected with sensor by wire and to realize signal detection and control, realize dripping velocity modulation joint, liquid level signal display alarm.
as preferably, be carry out tracer liquid by reflection infrared sensor to drip speed in described funnel.
as preferably, described flow regulator by cylindrical cam groove, slide bar, supporting seat, tiltedly carve groove, the column indenter indentation is formed, realize extruding tube for transfusion degree of tightness and realize Flow-rate adjustment.
This utility model solves the multiple medical treatment and nursing problems such as Medical transfusion tests the speed, speed governing, bubble detection, alarm, be directly installed on general medical transfusion pipe with a kind of standard modular interface, be beneficial to portable installation, portable use rapid Design interface attach most importance to, the safety not affecting Safety in Medical Equipment and medical and nursing work is target, simplify nursery work, Standard Nursing manages, and improves nursery work efficiency, improves nursing quality.And adopt various detection module and alarm module, effectively detect liquid level when infusing in dropping bottle, and a speed can be set.Be core with microprocessor in adjustment, be aided with necessary external circuit, detected by photoelectric sensor and drip speed.When the next machine testing to real-time dropping speed and setting value have a deviation time, then adopt online self-adjusting Intelligent Fuzzy Control algorithm, obtain the number of steps of motor, thus make motor forward or reverse, promote liquid storage piping clip by column type cam mechanism advance or retreat, the speed realizing dropping speed regulates, and makes it to reach setting value.This online self-adjusting Intelligent Fuzzy Control algorithm makes speed control system of dripping reach good dynamic and static quality, achieves in infusion process and drips comparatively accurately controlling of speed, and by software set, locks the speed adjusted.
