Abstract
The invention relates to a double-way unintermittent infusion set and belongs to a medical infusion set. The double-way unintermittent infusion set comprises bottle plug puncture units, an air inlet pipe air filter, a dropper and a needle which are sequentially connected through a hose, and a flow adjuster is sleeved on the hose. The double-way unintermittent infusion set is characterized in that the infusion set further comprises a tee joint, two branch tubes of the tee joint are connected with two infusion tubes, each infusion tube is provided with one bottle plug puncture unit and a one-way valve. The double-way unintermittent infusion set has the advantages that when a patient is subjected to infusion of multiple bottles of liquor medicines continuously, infusion medicine bottles can be automatically switched, unintermittent infusion is realized, burden of medical staff is alleviated, infusion efficiency is improved, and the problems of waste of liquor medicine, air entering the tubes and blood return and the like are avoided. The double-way unintermittent infusion set can be widely used for one-off infusion of various patients.
Description
Technical field
The present invention relates to a kind of medical apparatus, relate in particular to a kind of disposable transfusion device.
Background technology
The disposable medical transfusion device comprises the air inlet pipe air filter, bottle plug puncture unit, drip kettle and injection needle, they have have once connected and composed infusion path by the plasticity transparent hose, be set with flow regulator on the flexible pipe, when patient once needs to input many bottles of liquid, use the disposable transfusion device of this routine to infuse, then whenever be totally lost one bottle and will change timely next bottle, and the time of changing bottle should be that time of just in time being totally lost at medicinal liquid, if change in advance bottle, medicinal liquid does not also drip off, and just has the phenomenon of waste, if patient or nurse personnel fall asleep, do not stare at medicine bottle, in time do not call out medical personnel, postponed to change bottle, will advance a lot of air in the infusion path, even blood back, advance in the pipeline to change bottle behind the air and also want aerofluxus, cumbersome.Because the patient who infuses in many hospitals is usually a lot; allow limited medical personnel can both arrive in the bottle of changing dressings in that of short duration Best Times section of tens seconds of only having that medicine just drips off at every turn; be difficult to realize; therefore use conventional disposable transfusion device the phenomenons such as liquid waste, pipeline air inlet, blood back often can occur; now the disposable transfusion device that can prevent return blood is arranged also, but thisly can only prevent return blood, if in time do not change dressings bottle; the waiting period in stopping infusion, also wasted a period of time.
Summary of the invention
The problem to be solved in the present invention provides a kind of infusion bottle that can automatically switch, and can realize the disposable transfusion device of free of discontinuities continuous transfusion.
In order to address the above problem, the technical solution used in the present invention is: two-way free of discontinuities transfusion device, comprise bottle plug puncture unit, air inlet pipe air filter, drip kettle and syringe needle, they connect successively by flexible pipe, be set with flow regulator on the flexible pipe, it is characterized in that: transfusion device also comprises a tee T, and two branched pipes above the tee T connect two infusion pipelines, all are provided with bottle plug puncture unit and check valve on every infusion pipeline.
Further improvement of the present invention, described check valve are the internally-arranged type check valve, and two internally-arranged type check valves (8) are separately positioned in two branched pipes above the tee T, tee T and the as a whole molectron of internally-arranged type check valve.
An again step of the present invention improves; the assembly that described tee T and check valve, a kettle are structure as a whole; two branched pipes on the tee T are made and are dripped the kettle structure; include dropper; the below is provided with the internally-arranged type check valve; the next door of two branched pipes also is provided with chemical feed pipe, is used for aerofluxus or carries out intravenous injection, chemical feed pipe overcoat protective cap.
When two bottles of client need continuous transfusions and when above, can use transfusion device of the present invention, two branch roads are connected respectively two medicine bottles, the position that one of them medicine bottle is hung is higher than the above height of body of another medicine bottle, check valve on the high medicine bottle place infusion path in position can be opened automatically, first transfusion; Check valve on the low infusion bottle place infusion path in position can be because of the pressure differential autoshutdown.After the medicinal liquid in the high infusion bottle in position was totally lost, the check valve on the low infusion bottle place infusion path in position can be opened automatically, continued transfusion, realized that free of discontinuities switches.If also have the 3rd bottle of needs to continue transfusion, then after first bottle is totally lost and in the time period of second bottle of this dozens of minutes before being totally lost, first empty bottle of being totally lost can be changed into the 3rd medicine bottle at any time, first second bottle of position of hanging raised before changing, after changing empty bottle, make second bottle position be higher than the height of the 3rd bottle of at least one body, like this after the second bottle liquid medicine is totally lost, can automatically open again the 3rd bottle of check valve on the infusion path, another realizes the free of discontinuities switching, and by that analogy, how many bottles no matter once need to infuse, can realize the free of discontinuities switching, and the requirement of exchange bottle optimum time point extended to dozens of minutes from tens seconds.
If there is not the requirement of sequencing between each medicine bottle, there is not pharmacological reaction yet, need not to reduce the empty bottle position when then changing bottle, need not to exchange height, operate simpler.
Compared with prior art, its advantage is: when the continuously defeated many bottle liquid medicines of client need, change dressings the bottle time requirement greatly relax, the personnel that protect that need not the seek medical advice bottle of changing dressings of when medicine bottle just in time drips off, coming, the infusion bottle that namely can automatically switch is realized the free of discontinuities continuous transfusion, has alleviated medical personnel's burden, improve the efficient of transfusion, avoid advancing in liquid waste, the pipeline generation of the phenomenons such as air, blood back.The present invention can be widely used in all kinds of patients' disposable infusion.
