Abstract
The utility model belongs to a medical appliance which solves the shortcoming existing in current safety infusion apparatus of bad sealing and safety performance. The utility model comprises a needle head, a rubber tube, an upper catheter, a lower catheter and a dropper with a floater inside, which is characterized in that both ends of the catheter whose liquid-discharging end forms an inverted-cone shape are respectively connected with a liquid outlet of the dropper and the lower catheter, and a drain plug connected with the floater is inserted into the catheter.
Description
This utility model belongs to medical apparatus and instruments, the safe transfusion system of the automatic closing pipe line of especially a kind of energy.
Common intravenous transfusion device is not owing to have automatic closing organ, in case defeated the finishing of liquid and when failing in time to dial pin, inner air tube just may enter vein and cause thromboembolism, but threat to life when serious.For this reason, people have proposed " safe transfusion system ", can be at the transfusion device of liquid is defeated when finishing automatic closing pipe line, " safe transfusion system " as Chinese patent CN2031290U number introduction, this transfusion device is by the purpose that a floating plug of being made up of water wing and latex thin film capsule reaches automatic closing pipe line is set in dropper, because the defective on the floating plug structure and material makes that this automatic sealing is tight inadequately, security performance is not good enough.
The purpose of this utility model provides a kind of rational in infrastructure, sealing is tight, security performance is good automatic closed medical Transfusion device.
This utility model comprise syringe needle, rubber tube, upper conduit and downcomer and in the dropper of buoyancy aid is arranged.
This utility model is achieved in that liquid outlet is that the two ends of the conduit of inverted cone are connected with downcomer with the liquid outlet of dropper respectively, and the water that is connected with buoyancy aid plugs in the conduit.
Above-mentioned water plug is connected with buoyancy aid by the vertical prismatic shape connecting rod, or is connected with buoyancy aid by tightrope.
The alarm switch that links to each other with alarm device is housed on the above-mentioned catheter wall.
During use in liquid enters dropper after, the water plug moves with liquid under the effect of buoyancy aid, liquid is when finishing, the water plug promptly clogs the inverted cone liquid outlet of conduit, reaches the purpose of automatic sealing.Since adopt vertical prismatic shape connecting rod or tightrope that the water plug is connected with buoyancy aid, the liquid flow in dropper and the conduit can not blocked, and, make water hold the hydraulic pressure that can keep certain beyond the Great Wall just because of adopting this structure, guarantee that sealing is tight.If on the catheter wall alarm switch is housed, then can stir copper sheet in the process that the water plug falls and close alarm switch, improved safety.
The utlity model has advantage rational in infrastructure, that sealing is tight, security performance is good.
Accompanying drawing 1 is a vertical prismatic shape connecting rod scheme of installation.
Accompanying drawing 2 is the A-A cutaway view.
Accompanying drawing 3 is the tightrope scheme of installation.
Further specify embodiment below in conjunction with accompanying drawing.
Buoyancy aid 3 adopts non-toxic medical plastic to make, dropper 4 and conduit 5 adopt the hard transparent non-toxic medical plastic to make, wherein, conduit 5 long 50mm, internal diameter 5mm, liquid outlet internal diameter 3mm, water plug 6 adopts no-toxicity medical rubber to make, vertical prismatic shape connecting rod 7 or tightrope 8 adopt non-toxic biocompatible material to make, wherein, connecting rod 7 long 60mm, 1 is upper conduit in the accompanying drawing, 2 is that downcomer, 9 is alarm switch, and assembling each parts by aforementioned manner promptly becomes this utility model.
