Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is specifically described, as Figure 1-3, a kind of new type auto fluid level control device, comprise dropping funnel 1 and the dropping funnel lid 2 being fixedly mounted on dropping funnel 1 upper surface, described dropping funnel lid 2 upper surface is provided with inlet 3, exhaust unit is provided with in described dropping funnel 1, described exhaust unit is by the exhaustor 4 being arranged on dropping funnel lid 2 upper surface, upper end is connected with the exhaustor 4 on dropping funnel lid 2 and lower end is provided with the air chamber 5 of opening, be fixedly mounted on a pair projection 6 on air chamber 5 inner surface, the air bleeding valve 7 and waterproof ventilated membrane 8 five part be arranged between air bleeding valve 7 and protruding 6 that are fixedly inserted into air chamber 5 lower ending opening are formed, described air chamber 5 is cylindrical chamber, the diameter of described exhaustor 4 is less than air chamber 5 interior diameter, described air bleeding valve 7 is one-way exhaust valve, described a pair projection 6 is symmetrical about the centrage of air chamber 5, and the distance of described a pair projection 6 is less than the diameter of air bleeding valve 7.
The feature of the present embodiment is, be provided with dropping funnel and the dropping funnel lid being fixedly mounted on dropping funnel upper surface, dropping funnel covers surface and is provided with inlet, exhaust unit is provided with in dropping funnel, exhaust unit covers surperficial exhaustor by being arranged on dropping funnel, the exhaustor that upper end and dropping funnel cover is connected and lower end is provided with the air chamber of opening, a pair that is fixedly mounted on air chamber inner surface protruding, the air bleeding valve and waterproof ventilated membrane five part be arranged between air bleeding valve and projection that are fixedly inserted into air chamber lower ending opening are formed, structure is simple, automatically be arranged to measure precisely, avoid manually-operated inaccuracy, alleviate the work difficulty of medical worker.
In the present embodiment, first by this new type auto fluid level control device access dropping liquid pipeline, the inlet that liquid is covered by dropping funnel automatically flows in dropping funnel, in dropping funnel, liquid upper surface raises gradually, at this moment the pressure above liquid also raises gradually, and when the pressure above liquid is elevated to a certain degree, the air bleeding valve valve of exhaust unit will be opened, to ensure inside and outside air pressure balance, this makes it possible to well to control stabilizing of liquid level in dropping funnel.
In the present embodiment, waterproof ventilated membrane have can liquid barrier again can through the benefit of gas, it can prevent external substance to the pollution of transfusion simultaneously, plays a very good protection to transfusion.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection domain of the present utility model.
