Description
Technical field
The present invention relates to medical instruments, and in particular to a kind of unattended safe transfusion system controlling water outlet with magnet.
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 be required for medical staff frequently to be observed, if not found by people after liquid flow is complete, meeting
There is a phenomenon where air to enter human body or blood backflow, the serious life security for going back entail dangers to patient.
To solve the problems, such as that will inject the when of finishing in injection avoids air from injecting human body, there are many achievement in research, such as
Chinese patent notification number CN2601096, discloses a kind of piston being used in drop, and wherein drop plug is integrally placed in bottle
In liquid, and to be cavity at the top of drop plug make drop plug float on the top of a dropping liquid.When dropping liquid will be used up, drop plug is with liquid
Face drops to bottle mouth position and contacts sealing with bottle wall by drop stopper shape, but come with respect to the internal diameter of dropping bottle due to drop plug
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 that is installed below floating body.Liquid medicine storage device is by top
Part, lower component and bottom parts are constituted, and upper-part bottom end is provided with along the uniformly distributed upper fin of inner periphery, and lower component inner wall is arranged
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 there are radial clearances to ensure that the float is not crooked between seal and lower fin.Floating body is under
It equally need to there are radial clearances between fin.
Chinese patent notification number CN101905052B, patent name：《Infusion is fixed and the dress of safe infusion sealing
It sets, the detent plug film of the infusion fixator is enough to cover the injection outlet of drop Storage Cup and detent plug is bonded really, single
The apparatus structure is complicated, the buoyancy and gravity of structure be all difficult to ensure fully achieving for design function, the especially device without
Method prevents backflow of blood.
More money infusion apparatuses of my design, being capable of automatic plugging water outlet, it is ensured that patient safety still will continue to be infused, just
May can not be that patient continues to be infused due to floating ball cannot voluntarily rise.
