Description
Technical field
The present invention relates to a kind of self-closed medical injection transfusion pipe, definitely say, relate to a kind of medical injection transfusion pipe of automatic left alone without help drip apparatus when having transfusion and dripping to the greatest extent, belong to the technical field of medical injection transfusion.
Background technology
Medical injection transfusion pipe is commonly called as infusion rubber tubing, is used for the medicinal liquid in medicine bottle or the medicated bag is imported in the mode of drop patient's vein.Traditional infusion rubber tubing is by the syringe needle of getting it filled, first leather hose, the striking dropper of China ink, second leather hose, flow regulator, the 3rd leather hose, bonder, fine leather hose and injection needle are formed: the two ends of first leather hose are enclosed within respectively in the top connection of the feed tube of the syringe needle of getting it filled and Mo Fei dropper, one end of second leather hose is enclosed within the lower contact of black striking dropper, one end of the other end of second leather hose and the 3rd leather hose is integrated, flow regulator is fixed in second leather hose in the mode of clamping second leather hose, the other end of the 3rd leather hose is enclosed within on the thick joint of bonder, and the two ends of fine leather hose are enclosed within respectively on the feed tube of the thin joint of bonder and injection needle.During use, the syringe needle of getting it filled is penetrated the rubber closure of medicine bottle or medicated bag; Again the vent needle of breather is penetrated rubber closure, install breather; Medicine bottle or medicated bag are suspended on the patient top to be located for about 1 meter; Flow regulator is left foot, the air in the emptying liquid-transport pipe-line (except the black striking dropper, its upper semisection is an air); Close flow regulator; Injection needle is penetrated patient's vein; Regulate flow regulator to per minute and close the symbol requirement by the number of drops of the striking dropper of China ink.Like this, the medicinal liquid in medicine bottle or the medicated bag is imported patient's vein in the mode of drop.The advantage of traditional infusion rubber tubing is that black striking dropper is a glass tubing, by the striking dropper of China ink, can clearly observe and monitor the dropping liquid situation in it at any time, i.e. patient's transfusion situation.The shortcoming of traditional infusion rubber tubing is someone to monitor patient's transfusion situation, and medicinal liquid will monitor before being about to drip to the greatest extent especially.As medicine liquid droplet to the greatest extent, the unmanned discovery then can cause patients'blood to flow backwards in injection needle, blood clotting blocks injection needle, in the time of need continuing to infuse as patient, must change infusion rubber tubing and patient is remake venipuncture, patient and medical personnel are all had inconvenience.
The Chinese utility model patent that the patent No. and denomination of invention are respectively ZL02230202.6 and " automatic close-type transfusion device " proposes a technical scheme that overcomes above-mentioned shortcoming.Main points are as follows.Traditional black striking dropper is improved: the upper half of black striking dropper is cylindrical, and following half is conical funnel shape; Enclose a bulb stopper in the striking dropper of China ink.Bulb stopper floats on the medicinal liquid face.Be about to drip to the greatest extent as medicinal liquid, the medicinal liquid face in the black striking dropper descends, and bulb stopper descends thereupon, falls into the funnel part of black striking dropper, last bulb stopper in the middle of funnel or middle following position stop, conical funnel is stopped up fully, close liquid-transport pipe-line automatically.The shortcoming of this technology is the medicinal liquid face that bulb stopper floats on black striking dropper all the time, makes the dropping liquid situation in the black striking dropper be difficult to see clearly.
Summary of the invention
The technical problem to be solved in the present invention is to release a kind of self-closed medical injection transfusion pipe, definitely says, releases a kind of medical injection transfusion pipe that automatic left alone without help drip apparatus when using up is dripped in transfusion that has.This tube for transfusion does not have the shortcoming of background technology, but the advantage of the technology of having powerful connections, and simple in structure, be easy to realize, use flexibly, be applicable to any situation, effective.
The present invention is that the black striking dropper that ZL02230202.6 proposes is improved for the technical scheme that solves above-mentioned technical problem and adopt: the upper half at the striking dropper of China ink is partly located out a hole, is coated with the leather bag of storage bulb stopper on it.
Now be described with reference to the accompanying drawings technical scheme of the present invention.
