Abstract
The utility model discloses an air inlet pipe for a transfusion device, which is composed of a puncturing needle, a connecting guide pipe and an air filter. The upper part of the connecting guide pipe is provided with a liquid filter with a needle holder. The liquid filter is movably connected with the connecting guide pipe. The utility model has the advantages of reasonable structure, simple operation, etc. When the physic liquor is injected into the transfusion bottle, the connecting guide pipe on the lower part of the air inlet pipe is pulled out of the needle holder of the liquid filter. A syringe is inserted into the needle holder, the physic liquor enters the transfusion bottle through the liquid filter, the physic liquor is filtered, and a bottle stopper of the transfusion bottle avoids repetitively puncturing.
Description
Technical field: this utility model belongs to technical field of medical instruments, 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, only play the air inlet effect.When filling medicinal liquid in infusion bottle, the reuse syringe passes bottle stopper and adds in the infusion bottle, owing to not through filtering, easily the bits of the rubber on glass chip and the bottle stopper are brought in the medicinal liquid, causes the transfusion complication.
Technology contents: 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 medicinal liquid through filtering transfusion device air inlet pipe.
For solving the problems of the technologies described above, this utility model has been taked following technical scheme: based on existing transfusion device air inlet pipe, form by puncture needle, connecting duct, air filter, its main points are to be provided with on connecting duct top the liquid filter of a band needle stand, and 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, air filter 5 successively, sets up the liquid filter 3 of a band needle stand 4 on the top of connecting duct 2, and liquid filter 3 is flexible connection with connecting duct 2.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 of bottom is inserted in the needle stand 4 behind infusion bottle filling medicinal liquid again.
Claims (2)
