[detailed description of the invention]
Below in conjunction with accompanying drawing, the present invention is described in further detail:
With reference to figure 1, a kind of device for transfusion device liquid filtering and anti-backflow, comprise container cavity 1, described container cavity 1 upper end is provided with feed tube 11, lower end is provided with drain pipe 12, it is characterized in that: in described container cavity 1, be provided with funnel type pallet 2, the buoyancy body 4 of an activity is provided with above pallet 2, the warhead form structure 7 matched with funnel type pallet 2 leaking hole shape is provided with bottom buoyancy body 4, consider that transfusion device first time uses and in normal infusion, solution successfully can flow into container cavity 1 from top to bottom, therefore be provided with a foil 9 at buoyancy body 4 top, one or more metal salient point 6 is provided with around foil 9 central point, and be provided with C type Magnet 8 around upper end central point outside container cavity 1.
With reference to figure 1, the pipe that leaks of described funnel type pallet 2 is provided with filtrate 3; Container cavity 1 sidewall below described funnel type pallet 2 is provided with solution and drips fast watch window 5.
With reference to figure 1, upper end of the present invention feed tube 11 is by being connected with tube for transfusion and transfusion bag (bottle) puncture needle etc., lower end drain pipe 12 is by being connected with tube for transfusion and venipuncture needle etc., when foil 9 and metal salient point 6 are firmly held by C type Magnet 8, metal salient point 6 withstands the inner tip of container cavity 1, has reserved space for solution can flow into smoothly.The liquid of transfusion bag (bottle) is under the effect of gravity and atmospheric pressure, flowing from top to bottom, (in the space namely above funnel type pallet 2) in container cavity 1 is dropped to along the outer of buoyancy body 4 through feed tube 11, and flow in funnel type pallet 2, because the pipe that leaks of funnel type pallet 2 is provided with filtrate, then funnel type pallet 2 liquid velocity that pipe flow goes out that leaks has flowed into liquid velocity slow (defining current difference) than feed tube 11, liquid in funnel type pallet 2 diffuses in (in the space namely above funnel type pallet 2) in container cavity 1 gradually, along with the increase of hydrops, in container cavity 1, the liquid level in (in the space namely above funnel type pallet 2) constantly rises, buoyancy body 4 can be suspended in container 1, at this moment operator takes off C type Magnet 8, drip fast watch window 8 by solution to observe solution and drip speed, whole infusion process normally works.
With reference to figure 1, after the liquid stream of transfusion bag (bottle) is complete, in container cavity 1, the liquid level of the space of pallet 2 upper end (i.e. in) declines, buoyancy body 4 declines thereupon, warhead form structure 7 bottom buoyancy body 4 just in time matches with the inner chamber of funnel type pallet 2, thus stoping air to enter funnel type pallet 2 inner chamber and lower part, the liquid level in drain pipe 12 and lower end pipe stops to patient's infusion fluid.So, just reach and liquid filtered and does not have the self-braking object of liquid.
With reference to figure 1, when needing to change liquid, operator tilt more than 100 degree container cavity 1, and buoyancy body 4 slides into the inner tip of container cavity 1, now by around the top center point outside C type Magnet 8 placing container cavity 1, at this moment foil 9 and metal salient point 6 are firmly held by C type Magnet 8.Operator repeats the flow operations of first time transfusion.
It is last it is noted that above-described embodiment is only clearly example of the present invention is described; and the restriction not to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here without the need to also infinite enumerating cannot be given to all embodiments, and thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
