Description

Transfusion system for infusion of small-amount of multi-group fluids

The present invention relates to disposable medical appliance.

When needs of patients during from intravenously administrable, generally be to use 10% glucose, 5% G/NS, physiological saline and so on liquid is made solvent, and the required medicine that feeds from vein is dissolved in an amount of above liquid iv drip.As the liquid commonly used of solvent normally with 250ml or the fill of 500ml standard infusion bottle.Work as the patient, especially pediatric patient, must controlling liquid always go under the situation of the maybe necessary control drug level of amount, in the time of must importing multiple medicine again respectively, be medicine to be dissolved in respectively successively be mixed with different liquid (medicine must be made into liquid when the infusion temporarily sometimes) in the solvent, the total amount of its liquid is in span of control, the common solvent of this situation is a liquid of the same race, the amount of liquid of the amount of its every group of liquid and standard infusion bottle institute splendid attire than big difference, therefore very inconvenient when preparation and infusion, and there are many risk factors in the method that has.For example certain patient needs to use A, B, C, D, five kinds of medicines of E from vein, dissolve in the intravenous drip of 50ml10% glucose successively respectively, the nurse is when carrying out treatment, because of the amount of liquid of every group of liquid less, the open transfusion of general employing is prepared infusion in order respectively, it operates roughly, and step is: (1) opens the infusion bottle aluminium lid, does not pollute bottleneck, earlier to spill smart cotton swab sterilization bottleneck; (2) with 75% alcohol disinfecting thumb, food, middle finger, it is standby to take off loose rubber closure with finger; (3) open the transfusion bag; (4) open the infusion bottle bottle stopper, behind the flushing bottleneck, the liquid of falling 20-30ml is in the transfusion bottle of opening bottle cap, and flushing transfusion bottle and leather hose, liquid flow in the kidney basin; (5) fall needed liquid 50ml in bottle, syringe adds A, the lid lid, and transfusion bottle is hung on the drip stand; (6) stamp garter for patient; Treat that first group of liquid is totally lost, basic again according to above operating procedure (1), (2), (5) on the drip stand of ward, for patient prepares second group of liquid, treat that second group of liquid is totally lost after, repeat above operation more repeatedly, all be totally lost until medicine.This method is when compounding pharmaceutical, and medicine and utensil are isolated from the outside not good, especially operates in the bad ward of air sterillization, medicine and utensil easily take place pollute, and sterilization all can not cause hospital's sexuality to be dyed when reaching effect; Most of regional transfusion bottles and tube for transfusion are through flushing, and the non-once article that use repeatedly after the sterilization are not easy to clean up, and cause patient that serious transfusion takes place in infusion process, anaphylaxis, even might threat to life.Therefore, superseded when open transfusion is given adult's transfusion in general hospital, only use in department of pediatrics.Though existing once property transfusion bottle is sold, it is handled through removing pyrogen, but price is more expensive, the article wave is useless bigger, cracky in the transportation, so the scope of application is wideless, and its use still is open transfusion, medicine is isolated from the outside bad, still has pyrogen or sensitizer enters in the liquid in medicine preparation and infusion process, contamination of heavy takes place with the transfusion bottle that uses repeatedly through sterilization in its operation.The nurse is when carrying out this treatment, also can adopt closed transfusion method infusion, promptly get five bottles of liquid dosage respectively and become five groups of liquid, but need to insert the infusion bottle bottle stopper before the dosing and bleed off unnecessary liquid respectively with disposable transfusion device, pull out transfusion device then, add A, B, C, D, E with syringe successively respectively, changing transfusion device is patient infusion with transfusion device bottle stopper insertion syringe needle insertion transfusion bottle stopper successively.The more open transfusion of this method is mingled with pyrogen, sensitizer and generation opportunities for contamination and wants much less, but on transfusion bottle stopper, to insert the transfusion device bottle stopper repeatedly and insert syringe needle and injection needle, may cause occurring in the liquid crumb of bottle stopper, also increase the drug contamination chance simultaneously.The wave of liquid is useless bigger in the liquid dosage process, and useless equipment, and the disposable transfusion device that tapping is used can not be patient infusion again.When a large amount of patients needed infusion of small-amount of multi-group fluids, this method was difficult to realize.More than two methods preparations infusion of small-amount of multi-group fluids all very inconvenient.

The present invention will provide a kind of can prepare infusion of small-amount of multi-group fluids continuously, rapidly, easily, can reduce the disposable transfusion device to the invasive operation of transfusion bottle stopper again.

Agent structure of the present invention is identical with existing disposable transfusion device, on the existing transfusion device to being followed successively by down: 1. transfusion bottle stopper inserts syringe needle, 2. trachea, 3. dosing mouth, 4. Mo Feishi manages, 5. leather hose, 6. nipple, 7. piston.Hose connection between from 1 to 6 each parts by suitable length, structural feature of the present invention is on above architecture basics, increase by one and have the graduated liquid storing bag 8 of molten amount between 1 and 3, there is suppending hole 10 its top, in the part near liquid storing bag 8 dosing inlet 9 and flap 11 is arranged.One piston or pipe clamp can be arranged to control its switch on flexible pipe above the liquid bag or trachea.Still above treatment is example, open infusion bottle aluminium lid central authorities, put net, insert transfusion device on the bottle stopper and insert syringe needle, chucking piston 7 is hung on liquid bottle and liquid storing bag on the drip stand, adjust the relative position between liquid storing bag and liquid bottle, make the flow direction liquid storing bag, to 50ml, position to the liquid of adjusting the two again stops to flow to liquid storing bag; Open the lid on the dosing mouth 9, syringe adds A in liquid storing bag, and the lid lid promptly can be patient and stamps garter.Treat that first phase group liquid is totally lost, adjust the position between liquid storing bag and liquid bottle again, transfer the flow direction liquid storing bag to 50ml, 9 adding B get final product from the medicine mouth, and repetitive operation to five group liquid is totally lost.Liquid storing bag also can hang over infusion bottle below, with above the liquid storing bag or the piston on the trachea or pipe clamp come controlling liquid by infusion bottle to the mobile switch of liquid storing bag.

The present invention can remove pyrogen, and allergin is isolated from the outside well medicine, can effectively prevent drug contamination, makes disposable transfusion device more perfect.

Below in conjunction with the accompanying drawing embodiment that has a talk.

With the material of producing existing disposable transfusion device, make transfusion bottle stopper and insert syringe needle 1, trachea 2, this Guan Weiduan is provided with the air filtration thing, dosing mouth 3,9, lid 11,12 Mo Feishi pipe 4, leather hose 5, nipple 6 has the liquid filtering thing in the nipple, piston 7, liquid storing bag 8, this bag are gone up and are printed scale, and beat suppending hole 10.With flexible pipe above-mentioned part is assembled by figure, promptly become the present invention.
