Abstract
The utility model belongs to the technical field of a transfusion system, particularly a transfusion air inlet device which can prevent the ash and pathogen in the air from entering into the transfusion bottle. The utility model is composed of two parts of an inlet passage an exhaust passage. An inlet needle and an exhaust needle are concentric-sleeve type integrated needles, the inlet needle is positioned on the outboard of the exhaust needle, the height of an exhaust vent is higher than the liquid-surface height in a medical liquid bottle in transfusing, and the height of the inlet needle is lower than the height of the exhaust needle. The inlet needle is fixed on the upper end of a base 2, and the exhaust needle is fixed on the lower end of the base 2. A base 1 and a base 2 which are all provided with inner chambers are fixed together. An exhaust pipe is positioned in the inner chamber of the base 1, and the inner chamber is provided with an opening. The utility model has the advantages of simple structure and easy use, and prevents the ash and the pathogen from entering into the transfusion bottle.
Description
(1) described technical field
This utility model belongs to the technical field of transfusion device, particularly a kind ofly prevents that dust, pathogenic bacteria etc. in the air from entering the transfusion air intake installation of infusion bottle.
(2) background technology
With disposable hanging bottle type transfusion device is that the representative closed transfusion is the infusion model that extensively adopts clinically at present, is made of disposable infusion bottle and disposable transfusion device two parts usually.Wherein disposable transfusion device is made up of air inlet pipe, tube for transfusion, air filter, control valve and syringe needle again.Although this kind infusion vessel is sealed glass jars (or plastic bottle), but still need air unanimity with maintenance bottle inner and outer air pressure in air inlet pipe enters infusion bottle, make transfusion to instil smoothly.Though at present on the transfusion device air filter is housed, this ultimate filter is lower to the microgranule rejection rate below the 5um, macromole dust in the FA simply, and can't filtering to a large amount of little dust, pathogenic bacterium and the virus that exist in the transfusion environment.The air that constantly enters makes infusion bottle become Drexel bottle, and microorganism and little dust are easy to be brought in the human body by medicinal liquid, threatens patient's health.
(3) summary of the invention
The purpose of this utility model is to provide a kind of transfusion air intake installation simple in structure, easy to use, and can avoid pathogenic bacteria and virus to enter infusion bottle.
The purpose of this utility model is achieved in that
The utility model discloses a kind of transfusion air intake installation, form by inlet channel and exhaust passage two parts; Inlet channel is connected with air inlet connector, air inlet gas filtration film, air inlet pipe, base 2 in turn, has the air inlet needle of air inlet; The exhaust passage is connected with exhaust needle, exhaustor, the air filtration film that has steam vent in turn and cover the air filtration mould that has passage; Air inlet needle and exhaust needle are concentric locking collar cartridge type one body acupuncture, and air inlet needle is positioned at the outside of exhaust needle, the height of liquid level in the medicinal liquid bottle when height of steam vent is higher than transfusion, and the height of air inlet needle is lower than the height of exhaust needle; The height of steam vent is a little less than the height of infusion bottle; Air inlet needle is fixed on the upper end of base 2, and exhaust needle is fixed on the lower end of base 2; Base 1 and base 2 are fixed together, and inner chamber is all arranged; Exhaustor is positioned at the intracavity of base 1, and inner chamber has an opening.
Transfusion air intake installation of the present utility model in order to punch, is connected with bottle plug puncture unit on the air inlet connector on the bottle stopper of medicinal liquid bottle.
Transfusion air intake installation of the present utility model, the interior intracavity of base 1 has a baffle plate, and baffle plate is fixed on two side panels of base 1, highly is lower than the height of base 1 inner chamber.Can block a spot of medicinal liquid.
Transfusion air intake installation of the present utility model, can with interior " medical gas-filled bottle " supporting use that is filled with the high pressure clean gas.Aseptic, no thermal source in " medical gas-filled bottle ", the clean gas of no pathogenic bacterium enter disposable infusion bottle by this device, replace the air intake duct of traditional infusion device, finish normal transfusion.Because gas pressure is in barotropic state all the time in the infusion bottle, outside air can not enter infusion bottle, thereby makes whole infusion process safe and reliable.Gas enters the medicinal liquid bottle by the inlet channel I of this device in the bottle, and clean gas unnecessary in the medicinal liquid bottle is discharged the medicinal liquid bottle through exhaust passage II, makes not occur sudden and violent bottle phenomenon because of the quality problems of infusion bottle in infusion process.Simultaneously, in the time can not finishing transfusion because of the gas in " medical gas-filled bottle " is not enough, the air in the atmosphere also can enter the medicinal liquid bottle through exhaust passage II, thereby finishes normal infusion.
Using method of the present utility model is at first inserted bottle plug puncture unit the bottle stopper of infusion bottle, extracts bottle plug puncture unit.Exhaust needle and air inlet needle are aimed at the position of having punched insert infusion bottle vertically downward, all enter in the transfusion device up to air inlet needle.Infusion bottle is inverted, and when carrying out normal infusion, steam vent is higher than the liquid level in the medicinal liquid bottle.The medical gas-filled bottle that clean gas is housed is connected with the air inlet connector.Carry out other transfusion operation then.
The beneficial effects of the utility model are, have simple in structurely, easy to use, have prevented that dust, pathogenic bacteria and virus from entering infusion bottle.
