Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the present invention is described in detail.
As it is shown in figure 1, the present embodiment a kind of can automatic fitration, aerofluxus, automatic liquid-stopping, delay the infusion set of blood back,
Including upper cover 1, lower cover 2, being provided with filtration only liquid film 3 between described upper cover 1 and lower cover 2, described upper cover 1 includes one
Base 11 and be arranged at the drainage system 12 on this base 11；
Described drainage system 12 includes that the drain fixed part 121 being arranged on base 11 blocks with described drain fixed part 121
The drain movable part 122 connect, is provided with filtration between described drain fixed part 121 and the binding face of drain movable part 122 and draws
Stream film 123；The bottom of described drain movable part 122 offers liquid-inlet 124, and the top of drain movable part 122 is offered
There is air vent 125；The bottom of described drain fixed part 121 offers the liquid outlet 126 connected with lower cover 2, and drain is solid
The top determining portion 121 offers and filters the liquid through-hole 127 that drain film 123 connects.
It is provided with the binding face cooperated, in this laminating between drain fixed part 121 and the drain movable part 122 of the present invention
Arranging described filtration drain film 123 between face, described drain fixed part 121 preferably passes through clamping with drain movable part 122
Mode realizes removably connecting, it is simple to filter installation and the replacing of drain film 123.
Concrete, the present invention can automatic fitration, aerofluxus, automatic liquid-stopping, delay blood back infusion set operation principle such as
Under:
The liquid upper conduit 8 through being connected with needle for inserting bottle 7 flows into dropping funnel 4, is then passed through the liquid of the bottom of drain movable part 122
Body import 124 enters the inner chamber of drain movable part 122, through liquid through-hole 127 after described filtration drain film 123
Entering the inner chamber of drain fixed part 121, the inner chamber along drain fixed part 121 fills from described drain down through liquid outlet 126
Put 12 outflows, stop liquid film 3 through described filtration and enter lower cover 2, finally enter the downcomer 9 being connected with lower cover 2, finally
To transfusion needle.
The present invention has multinomial technological innovation and obtains beneficial effect, first, respectively through filtration in the flow process of liquid
Drain film 123 and filtration only liquid film 3, it is achieved the cascade filtration to liquid, it is possible to obtain good filter effect；Secondly,
By being arranged on the air vent 125 on drain movable part 122 top of drainage system 12, and the bowl-shape and groove knot of lower cover
Gas can be discharged in infusion process by structure automatically, it is ensured that being smoothed out of infusion process；Again, after transfusion stops,
Remain in liquid in dropping funnel 4 under the siphon principle effect filtering drain film 123, form trace infusion mode, to transfusion
Syringe needle position forms continuous positive pressure, reaches the purpose delaying blood back, anti-tampon and vasculitis to be formed；Finally, when dropping funnel 4
The liquid of interior residual is after trace infusion mode drips off completely, and a small amount of liquid can be gathered at filtration only liquid film 3, shape
Become gravity equalization of strain, reach the purpose of only liquid.
Wherein, the periphery of described base 11 is arranged at the draw-in groove for connecting dropping funnel 4, and described draw-in groove is by along base 11 upwards
The outer wall extended and an inwall are constituted.
Wherein, described lower cover 2 is in bowl structure, and centre is provided with the fluid passage 5 for being connected with downcomer 9.
Further, described fluid passage 5 is internally provided with groove 6, and the length of described groove 6 is preferably 3～12mm,
Width is 1～5mm, and during transfusion, the gas entering lower cover 2 can be extruded and ensure to enter by described groove 6
The liquid of downcomer 9 does not contains gas, it is ensured that the safety of infusion process be smoothed out.
As preferably, described drainage system 12 is in cylinder or rectangular-shaped.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but can not
Therefore the restriction to the scope of the claims of the present invention it is interpreted as.It should be pointed out that, for the person of ordinary skill of the art,
Without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
