Specific embodiment
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition
The concrete meaning of language in the present invention.
As shown in Figure 1, Figure 2 and Figure 3, the utility model discloses a kind of automatic liquid-stopping filtering dropping funnel, comprising: dropping funnel ontology and
Automatic liquid-stopping filter device, the dropping funnel ontology include cavity 1, puncture outfit, air inlet 7, inlet channel 2 and feed pathway 3, institute
The fluid hole 5 and feed pathway 3 for stating 2 lower end of inlet channel are connected to the cavity 1, and 1 lower end of cavity is equipped with exhaust outlet
12 and automatic liquid-stopping filter device 10, the automatic liquid-stopping filter device 10 is set to inside the cavity 1, the automatic liquid-stopping mistake
Filter device 10 is additionally provided with choke filter membrane 11, and the top and bottom of the automatic liquid-stopping filter device 10 are respectively equipped with gas vent 9
With liquid outlet 13,9 upper end of the gas vent covering stops liquid air ventilation membrane 8, and the gas vent 9 is connect with the exhaust outlet 12, described
Liquid outlet 13 is pierced by the cavity 1, for liquid to be discharged.Specifically, puncture outfit (not marking in figure) is for penetrating medicinal liquid bottle.
Wherein, the shape of the automatic liquid-stopping filter device 10 is the one or more of cylindrical body, cone and cuboid etc.
Combination.As shown in Figures 2 and 3, automatic liquid-stopping filter device 10 is preferably cylindrical body.
Wherein, the automatic liquid-stopping filter device 10 is emptied for middle section, and the choke filter membrane 11 is wrapped in described
Empty part.Medical fluid is emptied from centre partially passes through choke filter membrane 11, and gas stops from 10 upper end of automatic liquid-stopping filter device
Liquid air ventilation membrane 8 passes through, and realizes from degassing function.
Wherein, the inlet channel 2 is additionally provided with head protector 6 and sky crosses film 4, is connected to for dropping funnel with outside air, controls
Air pressure in dropping funnel is identical as the external world.
It as shown in Figure 4 and Figure 5, is simple function dropping funnel and simple function filter.
As shown in fig. 6, the utility model is also disclosed a kind of automatic liquid-stopping filtration system, including automatic liquid-stopping filtering dropping funnel,
Medicinal liquid bottle A, automatic liquid-stopping filter dropping funnel B and adjuster C.
A kind of working method of automatic liquid-stopping filtration system is also disclosed in the utility model, comprising: puncture outfit is inserted into medical fluid
In bottle, opens head protector outside air and entered in cavity through air inlet by inlet channel；Due to atmospheric pressure effect medical fluid pass through into
Liquid channel, fluid hole enter dropping funnel；Air in dropping funnel is stopped liquid air ventilation membrane, gas vent, exhaust outlet discharge, the liquid level in dropping funnel
Rise；
When liquid level is higher than only liquid air ventilation membrane, gas pressure at this time and external atmosphere pressure phase can not be discharged in the gas in dropping funnel
Together, the liquid level in dropping funnel remains unchanged, and realizes the function of control liquid level；
The liquid in adjuster dropping funnel is opened under the effect of gravity through choke filter membrane, automatic liquid-stopping filter device hollow portion
Divide and be discharged from liquid outlet, since the gas in liquid is discharged can not with liquid in the choke function of choke filter membrane, is formed
Gas-liquid separation, gas are stopped the discharge of liquid air ventilation membrane, and liquid is discharged through choke filter membrane, do not have bubble generation in liquid, without doctor
Shield personnel first squeeze dropping funnel, then it is time-consuming and laborious remove discharge bubble, both ensure that the safety of patient, and also mitigated medical staff's
Working strength is realized from degassing function；
Due to the intrinsic gas of choke filter membrane after emptying rate of liquid in dropping funnel ontology, automatic liquid-stopping filtering cannot be introduced into
So that its liquid is retained in automatic liquid-stopping device in device, plays the role of only liquid.In the vein pressure of human body be 600~900 millimeters
Water column, blood, which can not just flow back, when suitable with human vein pressure when dropping funnel body height is higher than 600~900 millimeter of water plays
The function of return blood.
The above is only the preferred embodiment of the utility model only, be not intended to limit the utility model it is novel, it is all
Within the spirit and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in practical
Within novel protection scope.
