Description

Venous transfusion health air bag

This utility model venous transfusion belongs to the medical and sanitary products technical field with the health air bag.When infusing for venous patient, use is charged in the infusion bottle by the air of the health cleaning that it stores, can prevent in the ward because the air severe contamination, and airborne virus, pathogenic bacteria, flying dust are infiltrated among the medicinal liquid, cause the malpractice of patient infection other diseases in the input patient body.

The doctor is when carrying out venous transfusion to patient now, generally all use original-pack normal saline bottle or glucose solution bottle to do infusion bottle, this vial is hung upside down on the drip stand of sick bed eminence, the bottle stopper puncture needle on transfusion device top is punctured in the infusion bottle by rubber bottle cover, the venipuncture needle of transfusion device bottom is pierced within patient's the vein.Also inserting an air inlet syringe needle on the rubber closure of infusion bottle in addition, the afterbody of air inlet syringe needle is generally connecting one section rubber tube as air inlet pipe, and the afterbody of this section air inlet pipe is drawn high liquid level in infusion bottle.After the transfusion beginning, the medicinal liquid under action of gravity in the infusion bottle constantly slowly flows among patient's the vein, and the outer air of infusion bottle constantly is inhaled in the bottle through air inlet pipe simultaneously.This strand air can form a lot of minute bubbles during by the bottle inner liquid medicine and pass medicinal liquid and arrive above the medicinal liquid, this is because infusion bottle is a hard shell body, after medicinal liquid flows out some in the infusion bottle, just produced negative pressure in the infusion bottle, and the air pressure inside and outside the air of air inlet pipe inspiration just can make infusion bottle reaches balance, and this just can make the medicinal liquid in the infusion bottle flow out continuously.

We know, because big city air pollution recently is serious day by day, airborne smog, dust, suspended particulates are a lot, in the ward, especially under the more situation of patient, the dust that the expectorant that patient tells, the spittle of cough, clothing shake hike up often makes the air pollution in the ward more serious, makes the harmful substances such as a lot of smog, virus, pathogenic bacteria, dust that suspending in the air in the ward.In these unclean air admission infusion bottles, pass medicinal liquid, and when reaching above the medicinal liquid, just some harmful substance is mingled among the medicinal liquid inevitably.After these contaminated medicinal liquid input patient's blood vessel, just may make the patient infection other diseases, the flying dust microgranule also may form embolus when flowing through blood capillary, stay potential harm to patient, causes malpractice.The generation that when giving patient infusion, how just can stop this malpractice? way is to fill the air of the health cleaning of into virus-free, no pathogenic bacteria, non smoke, free from dust in infusion bottle most effectively.This air that meets hygienic requirements is difficult to find in the relatively poor ward of condition, and the way of solution is to build air cleaner in the place of air cleaner.Air is handled through a series of scientific methods such as filtration, absorption, disinfection by ultraviolet light, sterilization, made it to become the air of non smoke, dustless, virus-free, aseptic health cleaning.How could store, to transport, use the air of this health cleaning easily? the purpose of this utility model provides a kind of venous transfusion health air bag, the air of the health cleaning that use is stored by its is when giving patient infusion, can make the medicinal liquid in the infusion bottle not contaminated, can stop the malpractice that causes because of air is unclean.

The purpose of this utility model is achieved in that with one section air-locked soft nontoxic tubular book plastics makes a kind of packaging bag of holding air, it has a rectangular bag 4 (seeing accompanying drawing 1, accompanying drawing 2), its top and bottom use the caking method that bag antetheca 7 and bag rear wall 8 is bonding firm respectively, form bonding limit 3, top and bonding limit 6, bottom, its both sides is original cylindrical body.3 places, bonding limit at its top establish the flexible plastic airway 2 of a negotiable air, and plastics airway 2 has the chance thermoplasticity, and its bottom is put in the bag 4, around it and 3 strong bond of bonding limit, top.The collar extension of plastics airway 2 is furnished with the medicated cap of keeping a public place clean 1.On bonding limit 6, bag bottom, be provided with hanging hole 5, be not communicated with in this hanging hole and the bag, have only plastics airway 2 can pass through air in the whole bag.Before unaerated, this bag 4 is its antetheca 7 of flat (seeing Fig. 1, Fig. 2) and pastes mutually with rear wall 8, and after inflation, it is a bag of heaving (seeing Fig. 3, Fig. 4).During inflation, in sterilizing room, depress, will through the air of the health cleaning of sterilization after the dust removal process in plastics airway 2 fills into bag 4 (capacity in the bag 4 is allowed some leeway), then plastics airway collar extension be heated plastic packaging with aerating device at natural atmosphere.Put on the medicated cap 1 of keeping a public place clean.On inspection, air tight, just put in the outer packaging non-toxic plastic protective bag, the heating of outer packaging plastics protective bag bag mouth is secured boxing for later use.

(see figure 5) during use is removed outer packaging plastics protective bag, and bag 4 is hung upside down on the drip stand 10 by hanging hole 5, makes it be in the top of infusion bottle 11, and the medicated cap 1 of keeping a public place clean on 2 mouthfuls of the plastics airways is removed, and cuts off plastic packaging mouth 13.Plastics airway 2 is injected (or injecting in the air inlet pipe of disposable transfusion device) on infusion bottle air inlet needle 9 backshanks.Because medicinal liquid flows out the negative pressure that is produced through transfusion device 12,, make the inside and outside air pressure of infusion bottle keep balance in the infusion bottle 11 slowly with in the air inspiration infusion bottle of being adorned in the bag 4 11.Because bag 4 is made by soft book plastics, along with the discharge of air, its antetheca 7 and rear wall 8 are slowly pressed close to, and volume diminishes gradually, and can not form negative pressure.

With in the air input bag 4 of after treatment health cleaning the time, also can be earlier with the collar extension heating plastic packaging of plastics airway 2, at the top of seal bag or during the bottom, reserve an inflation inlet, after filling into air from the inflation inlet of this reservation, again this is reserved inflation inlet heating plastic packaging.

Volume of air in the air bag should be more bigger than the volume of the medicinal liquid in the infusion bottle of preparing adapted, and the air bag that can be made into various volume specifications is standby.Air bag can be made with nonpoisonous flexible plastic, and also available other non-toxic high molecular materials are made.Its bag also can be made different shape as required.

Accompanying drawing 1: front view (unaerated), accompanying drawing 2: right view (unaerated), accompanying drawing 3: front view (inflation back), accompanying drawing 4: accompanying drawing 3A-A is to cutaway view, accompanying drawing 5: operation principle sketch map.

1 medicated cap of keeping a public place clean, 2 plastics airways, bonding limit, 3 tops, 4 bags, 5 hanging holes, bonding limit, 6 bottoms, 7 bag antethecas, 8 bag rear walls, 9 air inlet needle, 10 drip stands, 11 infusion bottles, 12 transfusion devices, 13 plastic packaging mouths.

The utility model sanitary air bag for venous transfusion is manufactured uncomplicated, and is stored by it The air of sanitary cleaning can guarantee health, be convenient to store, be convenient to transportation, easy to use, Can't thoroughly improve under the condition of air pollution in the ward at present, use it to have Effect ground prevents that soup in the infusion bottle from by unclean air pollution, can stop to be subjected to owing to soup The venous transfusion malpractice of polluting and taking place.
