Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of precision liquid medicine filter.
Background technology
At present, disposable precision liquid medicine crosses filter infusion apparatus, the difference of it and general infusion set is only to the addition of a precision liquid medicine filter, in the use procedure of hospital, the phenomenon of exhaust problem can be there is in existing precision liquid medicine filter when medical personnel carry out infusion process, and the precision filter infusion set that market uses is when occurring exhaust problem phenomenon, precision liquid medicine filter can be inverted in medical personnel and be exhausted, this method for exhausting can not drain the air in filter.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposes a kind of structure simple, is convenient to the precision liquid medicine filter of aerofluxus.
The technical problems to be solved in the utility model is achieved through the following technical solutions.This utility model is a kind of precision liquid medicine filter, be characterized in: comprise upper cover and lower cover, lower cover chamber is provided with on the top of lower cover, the outer wall of lower cover chamber is provided with a circle positioning boss, upper cover chamber is provided with in the bottom of upper cover, the outer wall of lower cover chamber is provided with the locating slot coordinated with positioning boss, and described upper cover docks with lower cover and makes upper cover chamber and lower cover chamber form medical filtration chamber; Under cover the inlet being provided with and being communicated with medical filtration chamber by feed pathway and the liquid outlet communicated with medical filtration chamber by liquid outlet channel, the porch communicated with medical filtration chamber at liquid outlet channel is provided with liquid medicine filtering membrane, forms medical filtration passage between described feed pathway, medical filtration chamber, liquid medicine filtering membrane, liquid outlet channel; Cover the air vent being provided with and communicating with medical filtration chamber on described, be installed with blocking solution exhaust membrane in exhaust ports.
In a kind of precision liquid medicine filter technical scheme of this utility model, preferred technical scheme feature is further:
1, described inlet is arranged on the side of lower cover, and liquid outlet is arranged on the opposite side with inlet;
2, described liquid medicine filtering membrane is nylon or poly (ether sulfone) film;
3, described blocking solution exhaust membrane is politef blocking solution exhaust membrane.
Compared with prior art, this utility model structure is simple, be convenient to aerofluxus, and docked with lower cover by upper cover and form medical filtration chamber, utilization is arranged on the air vent covering and communicate with medical filtration chamber, and by be arranged on coordinating of exhaust ports blocking solution exhaust membrane, achieve the degassing function of equipment; Utilize the liquid medicine filtering membrane being arranged on the liquid outlet channel porch communicated with medical filtration chamber, achieve the choke function of equipment, ensure that air can not enter human body along with medicinal liquid, improve the safety of transfusion.
Accompanying drawing explanation
