Description
Technical field
The present invention relates to medical instruments, and in particular to a kind of safe infusion dress that can be used in the case where nobody looks after state
It puts.
Background technology
It is defeated in the liquid of disposable transfusion device generally using disposable transfusion device when hospital is infused
The middle part of pipe is sent all there are one aobvious drop room, in the upper end of aobvious drop room there are one feed liquor drip nozzle and outlet tube, it is observed that liquid
Flow velocity, in order to do corresponding adjustment.The process of infusion is generally all long, will change bottle or at the end of be required for curing
Shield personnel are frequently observed, if not found after liquid flow is complete by people, it may occur that air enters human body or blood backflow
The phenomenon that, the serious life security for going back entail dangers to patient.
To solve the problems, such as to avoid air to inject human body when parenteral solution will be injected and finished, there are many achievement in research, such as
Chinese patent notification number CN2601096, discloses a kind of piston for being used in drop, and wherein drop plug is integrally placed in bottle
In liquid, and for cavity drop plug is made to float over the top of a dropping liquid at the top of drop plug.When dropping liquid will be used up, drop plug is with liquid
Face drops to bottle mouth position and sealing is contacted with bottle wall by drop stopper shape, but come due to drop plug with respect to the internal diameter of dropping bottle
Small, in the case where dropping bottle stress rocks state, drop plug can arbitrarily roll in bottle and can not effectively seal bottle wall, reach detent plug work
With.
Chinese patent notification number CN1736500, discloses a kind of automatic controlling arrangement of transfusion system, and wherein float is set
It is placed in liquid medicine storage device, and float includes floating body and the seal being installed below floating body.Liquid medicine storage device is by top
Part, lower component and bottom parts are formed, and upper-part bottom is provided with along the uniformly distributed upper fin of inner rim, and lower component inner wall is set
There is peripherally uniformly distributed lower fin.Seal outer diameter is more than the radial dimension of inscribed circle between each upper fin to ensure the floating of float
Rise is restricted, and leaves radial clearance between seal and lower fin to ensure that the float is not crooked.Floating body is under
Radial clearance need to be equally left between fin.
Chinese patent notification number CN101905052B, patent name：《Infusion is fixed and the dress of safe infusion sealing
It puts, the detent plug film of the infusion fixator is enough the parenteral solution outlet for covering drop Storage Cup and detent plug is bonded really, single
The apparatus structure is complicated, and the buoyancy and gravity of structure are all difficult to ensure that fully achieving for design function, particularly the device without
Method prevents backflow of blood；Therefore, existing disposable transfusion device needs to improve.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of safety that can be used in the case where nobody looks after state
Infusion device.
The technical solution adopted by the present invention is as follows：A kind of safe transfusion device that can be used in the case where nobody looks after state,

Between be provided with magnet steel ring endoporus；The diameter dimension of magnet steel ring endoporus is identical with the diameter of magnet steel ring positioning tube；The magnetism steel ball
It is placed in the cavity among floating ball.
The central magnetic of the magnet steel ring is most strong, can attract each other between magnet steel ring and magnetic steel ball；The floating ball uses
Flexible material makes, and the diameter of floating ball is equal to the diameter of half spherical cavity；The floating ball can fall into and be placed in down when not having liquid
In half spherical cavity of side；After the floating ball is fallen into half spherical cavity placed below, magnetic steel ball can have been attracted by magnet steel ring；It is described floating
Ball is fallen into half spherical cavity, and after magnetic steel integument magnet steel ring has attracted, the through hole below floating ball is blocked by floating ball, and liquid and air are all
It cannot pass through through hole.
Using technical solution of the present invention, have the advantages that：
1）The configuration of the present invention is simple, does not add any circuit device, and security performance is high；
2）The present invention is using magnetic principle, and when not having liquid, floating ball can be fallen into half spherical cavity of lower section, the magnetic in floating ball
Property steel ball has been attracted by magnet steel ring, can be closed through hole tightly, can both have been prevented that air from entering, be also possible to prevent blood
It flows backwards；
3）The magnet steel ring of the present invention is mounted externally, belongs to detachable part, magnet steel ring can be removed and recycled, and be conducive to ring
It protects and saves.
