Technical field
The transfusion that the present invention relates to intravenous transfusion device completes detection technique category, particularly relate to a kind of base oneself upon infused with accumulator energy storage state from capacitation alarm and method thereof.
Background technology
One of major technique of administration when venous transfusion is clinical treatment, under emergency treatment, traumatic event, one preferred technique especially; Medical statistics data are pointed out, the inpatient of 90% ~ 95% need carry out infusion treatment.Intravenous transfusion device has puncture, conveying, metering, adjustment, filtration, connection, air inlet function, should also provide after-teeming function if desired.General infusion set drips kettle by protective sleeve for bottle stopper puncture outfit, bottle plug puncture unit, exhaustor, Mo Feishi usually, liquid medicine filter, tube for transfusion, wheel press from both sides flow regulator, scalp acupuncture and coupling and form, and the liquid level difference pressure by medical liquid container and patient fluid infusion position inputs medicinal liquid in patient body.In treatment, widely used disposable transfusion device starts from the U.S. of the sixties, introduces China then in the eighties; Disposable transfusion device adopts the manufacture of medical aseptic macromolecular material, ethane via epoxyethane sterilizing, be aseptic, nontoxic, without the medical device of pyrogen; Disposable transfusion device comparatively before latex tubing transfusion device be a large technological progress, not only safe and reliable, simple and easy to do, infusion reaction is few, and has effect solution Long phase of having determined to perplex the cross infection difficult problem of medical profession.2010, the disposable syringe output of China surpass 13,000,000,000, Year's consumption up to more than 50 hundred million, be the disposable medical instrument that range of application is the widest, quantity is maximum.
Along with widely using of disposable transfusion device, it is not enough and defect also shows especially gradually: in the overall process of intravenous drip, and whether medical personnel and the drip velocity must observing medicinal liquid with patient at any time of accompanying and attending to complete with transfusion; Obviously, plodding control has increased the weight of medical personnel and has accompanied and attended to bear with the psychology physiological of patient.Have benefited from improvement and the maturation of disposable transfusion device production technology, controllability and the stability of drip velocity become better and approaching perfection day by day; But there is no the simple effective solution of " whether transfusion completes " so far.Long-time manual observation " transfusion whether complete ", very easily causes medical personnel and accompanies and attends to neglecting with the observation of patient; Carelessness not only can produce the therapeutic process of patient incurs loss through delay, and even can have an impact, cause malpractice the life security of patient.Obviously, the inherent shortcoming that artificial monitoring " whether transfusion completes " exists urgently is improved.
The end of the eighties in last century, developed country hand propelled intravenous delivery system problem, successively obtains a series of achievement: as K-120 infusion pump, the USA I/M ED company GeminiPC-ZTX type transfusion device of the TOP-7100 type infusion pump of Japanese TOP Co., Ltd., German KNAUER company; The said goods function admirable, complete function, but the large and expense of expensive, the maintenance work amount of product remains high; Therefore, except ICU, its trace is difficult to find.Domestic correlational study can trace back to the mechanical type infusion bottle liquid-level detecting method [Yu Xiangying, the Developing Application [J] of novel spring infusion alarm, Nursing graduate education, 2003,17 (9): 1010] of research worker proposition in 85 years; At present, still there is larger gap in the aggregate level of domestic intravenous delivery system and commercialized degree and developed country.
