Description
(1) described technical field
This utility model relates to a kind of venous transfusion air intake installation, particularly a kind of split type transfusion air intake installation.
(2) background technology
The closed transfusion that is representative with disposable hanging bottle type transfusion device is the infusion model that extensively adopts clinically at present, is made of disposable infusion bottle (or plastic bag) 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.About the patent of transfusion air intake installation, be the Chinese patent of CN02255940X " transfusion air intake installation " as the patent No., be suitable for the transfusion air intake installation of the fixed glass infusion bottle of specification.For some soft plastic bottle or plastic bag, its specification is various, and long exhaust needle punctures plastic bag easily.
(3) summary of the invention
This utility model provides a kind of split type transfusion air intake installation simple in structure, easy to use in order to overcome above deficiency.
This utility model is realized by following measure:
The utility model discloses a kind of split type transfusion air intake installation, be divided into induction part and discharge portion, induction part is connected with air inlet needle, air inlet needle base, air inlet pipe, air inlet connector, protective cap in turn, the air inlet connector is embedded with air inlet gas filtration film, has the air inlet needle air inlet on the air inlet needle; The structure of discharge portion is, be fixed with the pressure balance pin on the pressure balance pin base, pressure balance pin base is embedded with pressure balance pin gas filtration film, has pressure balance faller gill pore on the pressure balance pin, is connected with the line that is flexible coupling between pressure balance pin base and the air inlet needle base.
Split type transfusion air intake installation of the present utility model for the pressure balance pin is fixed on the infusion bottle, is fixed with hook on the pressure balance pin base.
Split type transfusion air intake installation of the present utility model, it further is improved to: air inlet needle is with the outer sleeve pin outward, the height of outer sleeve pin is lower than the height of air inlet needle, and the air inlet needle air inlet is positioned at the bottom of air inlet needle, and an outer sleeve pin air inlet is arranged between outer sleeve pin and the air inlet needle.
Operation principle of the present utility model, purify aseptic, the no thermal source of source of the gas generation, the clean gas of no pathogenic bacterium,, enter disposable plastic transfusion bottle (bag) by air intake installation of the present utility model, replace the air intake duct of traditional infusion device, finish normal transfusion.Because the interior gas pressure of infusion bottle (bag) is in barotropic state all the time, outside air can not enter infusion bottle, thereby makes whole transfusion reliable.Clean gas enters plastics medicinal liquid bottle (bag) by the air inlet needle that is inserted in infusion bottle (bag) mouth, and unnecessary clean gas goes out plastics medicinal liquid bottle (bag) through a pressure balance faller gill split and that be inserted in medicinal liquid bottle (bag) top in the medicinal liquid bottle (bag).Simultaneously, when the gas purification source of the gas can not provide clean gas, the air in the atmosphere also can enter the medicinal liquid bottle through this pressure balance pin, thereby finishes normal infusion.
Air intake installation of the present utility model, air inlet needle is inserted the end opening of infusion bottle (bag), the top of pressure balance pin insertion infusion bottle (bag), and by dropper clamps on infusion bottle (bag), pressure balance faller gill pore is higher than the liquid level in the infusion bottle (bag), and unnecessary gas is discharged.The base of the base of air inlet needle and pressure balance pin links together with a flexible cord.
The beneficial effects of the utility model are to be suitable for the inlet and outlet of plastic bottle (bag), and to have advantage simple in structure, easy to use.
(4) description of drawings
Below in conjunction with accompanying drawing this utility model is made specific description
Fig. 1 is a kind of structural representation of the present utility model
