The specific embodiment
Below in conjunction with the drawings and the specific embodiments, this utility model is described in detail.
As shown in Figure 1, the present embodiment a kind of can automatic fitration, aerofluxus, automatic liquid-stopping, delay the infusion set of blood back, comprise upper cover 1, lower cover 2, between described upper cover 1 and lower cover 2, be provided with and filter only liquid film 3, described upper cover 1 comprises a base 11 and is arranged at the drainage system 12 on this base 11;
Described drainage system 12 comprise the drain fixed part 121 that is arranged on base 11, with the drain movable part 122 of described drain fixed part 121 clampings, between described drain fixed part 121 and the binding face of drain movable part 122, be provided with filtration drain film 123; The bottom of described drain movable part 122 offers liquid-inlet 124, and the top of drain movable part 122 offers air vent 125; The bottom of described drain fixed part 121 offers the liquid outlet 126 being communicated with lower cover 2, and the top of drain fixed part 121 offers and the liquid through-hole 127 that filters drain film 123 and be communicated with.
Between drain fixed part 121 of the present utility model and drain movable part 122, be provided with the binding face cooperatively interacting, described filtration drain film 123 is set between this binding face, described drain fixed part 121 is realized and being removably connected with the preferred mode by clamping of drain movable part 122, is convenient to filter installation and the replacing of drain film 123.
Concrete, the operation principle of infusion set of can automatic fitration, aerofluxus, automatic liquid-stopping, delaying blood back of the present utility model is as follows:
The upper conduit 8 of liquid through being connected with needle for inserting bottle 7 flows into dropping funnel 4, then the liquid-inlet 124 of the bottom of process drain movable part 122 enters the inner chamber of drain movable part 122, through enter the inner chamber of drain fixed part 121 after described filtration drain film 123 through liquid through-hole 127, inner chamber along drain fixed part 121 flows out from described drainage system 12 through liquid outlet 126 downwards, through described filtration, stop liquid film 3 and enter lower cover 2, finally enter the downcomer 9 being connected with lower cover 2, finally to transfusion needle place.
The utlity model has multinomial technological innovation and obtain beneficial effect, first, in the flow process of liquid, respectively through filtering drain film 123 and filtering only liquid film 3, realizing the cascade filtration to liquid, can obtain good filter effect; Secondly, by being arranged on the air vent 125 on drain movable part 122 tops of drainage system 12, and the bowl-shape and groove structure of lower cover can, automatically by gas discharge in infusion process, guarantee carrying out smoothly of infusion process; Again, after transfusion stops, remaining in liquid in dropping funnel 4 filtering under the siphon principle effect of drain film 123, form micro-infusion mode, infusion needle position is formed to continuous positive pressure, reach and delay the object that blood back, anti-tampon and vasculitis form; Finally, after the interior residual liquid of dropping funnel 4 drips off completely through micro-infusion mode, a small amount of liquid can be gathered in and filter only liquid film 3 places, forms gravity equalization of strain, reaches the only object of liquid.
Wherein, the periphery of described base 11 is arranged at for connecting the draw-in groove of dropping funnel 4, and described draw-in groove is by forming along the upwardly extending outer wall of base 11 and an inwall.
Wherein, described lower cover 2 is bowl structure, and centre is provided with the fluid passage 5 for being connected with downcomer 9.
Further, described fluid passage 5 inside are provided with groove 6, the length of described groove 6 is preferably 3～12mm, width is 1～5mm, in the process of transfusion, described groove 6 can be extruded the gas that enters lower cover 2 guarantee to enter in the liquid of downcomer 9 and not contain gas, the safety that guarantees infusion process with carry out smoothly.
As preferably, described drainage system 12 is cylinder or rectangular-shaped.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
