Abstract
The utility model discloses an air inlet tube for a transfusion device with a filter, which is composed of a puncture needle, connecting conduit tube and air filter. The utility model is characterized in that a liquor filter with a needle seat is arranged on and is movably connected with the connecting conduit tube. The utility model has the advantages of reasonable structure, simple operation, etc.; when a transfusion bottle is filled with medical liquor, the connecting conduit tube on the lower part of the air inlet tube is drawn out from the liquor filter, an injector is inserted into the needle seat, the medical liquor is led into the transfusion bottle through the liquor filter, and then, the medical liquor can be filtered; besides, a bottle plug of the transfusion bottle is prevented from being punctured repeatedly.
Description
Technical field: this utility model belongs to the medical apparatus technical field, relates to a kind of transfusion device air inlet pipe.
Background technology: the transfusion device air inlet pipe of prior art, form by puncture needle, connecting duct, air filter successively, pass bottle stopper by puncture needle during transfusion, enter and only play the air inlet effect in the infusion bottle.When filling medicinal liquid in infusion bottle, the reuse syringe passes bottle stopper and adds in the infusion bottle, because medicinal liquid is easily brought the bits of the rubber on glass chip and the bottle stopper in the medicinal liquid into not through filtering, causes the transfusion complication.
Summary of the invention: the technical problems to be solved in the utility model is, the problem of filling medicinal liquid filtered in infusion bottle, thereby provide a kind of in infusion bottle the filling medicinal liquid make the transfusion device air inlet pipe of medicinal liquid through filtering band filter.
For solving the problems of the technologies described above, the technical solution of the utility model is: based on existing transfusion device air inlet pipe, form by puncture needle, connecting duct, air filter, its main points are to be provided with the liquid filter of a band needle stand on connecting duct, liquid filter and connecting duct are for flexibly connecting.
The rubber bits are brought in the medicinal liquid when avoiding the lancet puncture bottle stopper, the venthole of said puncture needle is in a side of puncture needle body.
The utlity model has rational in infrastructure, simple operation and other advantages, when in infusion bottle, annotating medicinal liquid, the connecting duct of air inlet pipe bottom is pulled up from the needle stand of liquid filter, syringe is inserted needle stand, medicinal liquid enters infusion bottle by liquid filter, medicinal liquid is filtered, and avoided the repeated localised puncture of infusion bottle bottle stopper.
Description of drawings: accompanying drawing is this utility model structural representation.
The specific embodiment: with reference to the accompanying drawings, this utility model is made up of puncture needle 1, connecting duct 2,5 and air filter 6 successively, sets up the liquid filter 3 of a band needle stand 4 on connecting duct 2, and liquid filter 3 is flexible connection with connecting duct 2,5.Filling is inserted needle stand 4 with syringe during medicinal liquid in infusion bottle, and medicinal liquid enters infusion bottle by liquid filter 3, the connecting duct 5 of bottom is connected with needle stand 4 behind infusion bottle filling medicinal liquid again.
