Description
Technical field
The present invention relates to medical instruments, and in particular to a kind of safe transfusion system by magnet piece control water outlet.
Background technology
When hospital is infused, generally using disposable transfusion device.The process of infusion is generally all long,
Will change bottle or at the end of medical staff is required for frequently to be observed, if not found after liquid flow is complete by people, meeting
Generation air enters the phenomenon that human body or blood backflow, 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.
More money infusion apparatuses that the applicant has designed all are the magnet ring modes used, if the position that magnet ring is placed is bad,
There is a possibility that steel ball is attracted on one side of magnet ring, the effect for blocking water outlet can be undesirable.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of safe infusions by magnet piece control water outlet
Device.

Stating floating ball can swim among liquid, and the sub-fraction meeting emersion of the floating ball is on the face of liquid；When there is no liquid in inner cavity
During body, floating ball can fall on the inner cavity water outlet below inner cavity；The magnet is inserted into magnet socket, can be to falling in inner cavity water outlet
On floating ball in steel ball generate attraction.Steel ball is attracted by magnet, and steel ball can pull downward on floating ball.
The floating ball is made of flexible material, and floating ball, can slight deformation when the steel ball of intracavitary is attracted by magnet；It is described
After steel ball is attracted by magnet, floating ball can be pulled downward on, floating ball can seal inner cavity water outlet, after floating ball can seal inner cavity water outlet,
Liquids and gases cannot all pass through water outlet.
Using technical solution of the present invention, have the advantages that：
1）Magnet of the present invention to the attraction of steel ball and close water outlet position it is accurate；
2）The present invention is using magnetic principle, and when not having liquid, floating ball can fall into intracavity bottom, and the steel ball in floating ball can quilt
Magnet attracts, and makes floating ball closing inner chamber water outlet, can both prevent air from entering, is also possible to prevent backflow of blood, securely and reliably；
3）The magnet of the present invention detachably recycles.
