Abstract
The utility model discloses an infusion apparatus, which comprises a bottle plug puncture device, a drip, a flow velocity regulator, a medicine liquid filter and an intravenous needle which are sequentially connected by a flexible tube. A cylindrical tube plug capable of floating is arranged in the drip, the lower end of the tube plug is semispherical, and four support arms are arranged on the periphery of the lower portion of the tube plug and uniformly distributed around the tube plug and vertically extend outwardly. Since the tube plug capable of floating is arranged in the drip of the infusion apparatus, when the drip contains liquid, the tube plug is in the floating state under the action of buoyancy of the liquid and then the drip can drip normally; and when the drip contains no liquid, under the action of the self gravity of the tube plug, an outlet of the drip is closed, and then air can be effectively prevented from entering veins of a human body along the flexible tube.
Description
Technical field
This utility model relates to technical field of medical instruments, the transfusion device that uses when being specifically related to a kind of intravenous injection.
Background technology
In the intravenous injection process, the air admission vein is a comparatively dangerous thing.Behind the air admission vein, at first be brought to right atrium, enter right ventricle again,, make air and blood be mixed into cystose, and arrive whole body with blood circulation along with heartbeat along vein.If the air admission pulmonary artery can block its branch, blood can not be entered in the lung, cause severe depletion of oxygen and cause death.If the air admission heart coronary artery can block its circulation, cause serious cardiac dysfunction, cause death.
The utility model content
Technical problem to be solved in the utility model provides a kind of transfusion device, and this transfusion device is simple in structure, and is safe and reliable, in the time of can effectively stopping to infuse in the air admission vein.
For solving the problems of the technologies described above, this utility model has adopted a kind of like this transfusion device, and it comprises bottle plug puncture unit, dropper, flow regulator, liquid medicine filter and the intravenous needle that connects successively with flexible pipe; Being provided with in the described dropper can buoyant cylindric pipe close, and the lower end of pipe close is the semicircle sphere, and the periphery of described pipe close bottom is provided with four support arms, and four support arms are around the pipe close uniform distribution and vertically stretch out.
As further improvement of the utility model, the top of dropper is provided with dosing mouth.
The utility model has the advantages that: this kind transfusion device is provided with in dropper can buoyant pipe close, and when in the dropper liquid being arranged, pipe close is floating shape under the effect of liquid buoyancy, the normal dropping liquid of dropper.When in the dropper during no liquid, pipe close is under the effect of self gravitation, and the outlet sealing with dropper can effectively stop air to enter human vein along flexible pipe.Therefore, this kind transfusion device uses as safe as a house, patient's Use Limitation fruit that nobody is accompanied and attended to better.
Description of drawings
Fig. 1 is the structural representation at transfusion device dropper position.
The specific embodiment
In conjunction with Fig. 1, transfusion device comprises the bottle plug puncture unit, dropper 1, flow regulator, liquid medicine filter and the intravenous needle that connect successively with flexible pipe.Being provided with in the described dropper 1 can buoyant cylindric pipe close 2, and the lower end of pipe close 2 is the semicircle sphere.The periphery of pipe close 2 bottoms is provided with 4, four support arms of four support arms 4 and also vertically stretches out around the pipe close uniform distribution.Be provided with dosing mouth 5 on the top of dropper 1.
In the use, when in the dropper 1 liquid 6 being arranged, pipe close 2 is floating shape under liquid 6 buoyancy function, dropper 1 normal dropping liquid.When in the dropper 1 during no liquid, pipe close 2 is under the effect of self gravitation, and the outlet sealing with dropper 1 can effectively stop air to enter human vein along flexible pipe.
Claims (2)
1. a transfusion device comprises the bottle plug puncture unit, dropper, flow regulator, liquid medicine filter and the intravenous needle that connect successively with flexible pipe; It is characterized in that: being provided with in the described dropper can buoyant cylindric pipe close, and the lower end of pipe close is the semicircle sphere, and the periphery of described pipe close bottom is provided with four support arms, and four support arms are around the pipe close uniform distribution and vertically stretch out.
