Description
Technical field
The utility model relates to a kind of efficient liquid medicine filters, belong to field of medical products.
Background technique
Due to there are a large amount of various particles in medical fluid, so infusion apparatus is designed with liquid medicine filter.General infusion apparatus institute
The particle of 20 microns of liquid medicine filter intelligent filtering diameter or more, filter membrane used are coarse filtration film.And it is deposited in medical fluid
Most in 5~20 microns of particle number of diameter, harm is maximum.Therefore, with 5 microns of filter diameter of energy or more of particle mistake
The infusion apparatus of filter membrane is known as precision filter infusion set, but the filter opening very little of secondary filter, influences the flow and flow rate of infusion.
Summary of the invention
In view of the deficiencies of the prior art, the medical fluid mistake good the utility model proposes a kind of filter efficiency height, filter effect
Filter.
The utility model technical scheme applied to solve the technical problem is: a kind of efficient liquid medicine filter, including is used for
The upper conduit and downcomer connecting with perfusion tube, the liquid medicine filter include upper filter chamber and lower filter chamber, the upper mistake
Filter chamber is connected to the upper conduit, and the lower filter chamber is connected to the downcomer；The upper filter chamber and the lower filter chamber
Between separated by a filter membrane, secondary filter film is equipped in the lower filter chamber；The periphery of the upper filter chamber is equipped with row
Air cavity is separated between the discharge chamber and the lower filter chamber by air-guiding film, and the top of the discharge chamber is equipped with several rows
Stomata；Filter membrane is coarse filtration film, may filter that particle of the diameter at 20 microns or more in medical fluid；Described two
Secondary filter membrane is secondary filter film, may filter that particle of the diameter between 5~20 microns in medical fluid.
Further, a filter membrane is horizontally disposed, the outer of a filter membrane and the air-guiding film
It is connected, the outer of the air-guiding film is connected with the inner wall of the filter.
Further, the secondary filter film is in spherical cap shape, the secondary filter film and the primary filtering
Film is connected with air-guiding film in same place.
Further, the secondary filter film is nanoparticle filter membrane.
Further, the bottom of the lower filter chamber is spherical cap shape, the bottom of the lower filter chamber and the downcomer
Connection.
In use, medical fluid is entered in upper filter chamber by upper conduit, medicinal liquid osmosis is described by entering after a filter membrane
In the range of secondary filter film surrounds, secondary filter film is then penetrated through again, into lower filter chamber, finally by downcomer stream
Out.
The beneficial effects of the utility model are: compared with prior art, the liquid medicine filter master of the offer of the utility model
There is following advantage:
1) for filter by filtering twice, a coarse filtration and a secondary filter, filter effect are more preferable；
2) the periphery setting discharge chamber of filter chamber on, the top of discharge chamber is arranged gas vent, has degassing function, can make
It filters more smooth；
3) secondary filter film uses spherical, big with the contact area of filtrate；Since the filter opening of secondary filter film is smaller, increase
The area of big secondary filter film improves the rate of filtration of filter entirety so that the flow velocity entirely filtered is unaffected.
Detailed description of the invention
Fig. 1 is the cross section structure schematic diagram of the liquid medicine filter provided in the utility model.
Wherein, the upper conduit of 1-；The upper filter chamber of 2-；3- discharge chamber；4- air-guiding film；Filter membrane of 5-；Filter chamber under 6-；7-
Downcomer；8- secondary filter film；9- gas vent.
Specific embodiment
The utility model is further illustrated below by specific embodiment.But it is practical new that these examples are merely to illustrate this
Type rather than limitation the scope of the utility model.
Embodiment
As shown in Figure 1, a kind of efficient liquid medicine filter, including the upper conduit 1 and downcomer 7 for being connect with perfusion tube,
The liquid medicine filter includes upper filter chamber 2 and lower filter chamber 6, and the upper filter chamber 2 is connected to the upper conduit 1, described
Lower filter chamber 6 is connected to the downcomer 7；Between the upper filter chamber 2 and the lower filter chamber 6 by filter membrane 5 every
It opens, is equipped with secondary filter film 8 in the lower filter chamber 6；The periphery of the upper filter chamber 2 is equipped with discharge chamber 3, the discharge chamber 3
It is separated between the lower filter chamber 6 by air-guiding film 4, the top of the discharge chamber 3 is equipped with several gas vents 9；Described
One time filter membrane 5 is coarse filtration film, may filter that particle of the diameter at 20 microns or more in medical fluid；The secondary filter film 8
For secondary filter film, particle of the diameter between 5~20 microns in medical fluid may filter that.The bottom of the lower filter chamber 6 is ball
The bottom of crown shape, the lower filter chamber 6 is connected to the downcomer 7.Filter membrane 5 be it is horizontally disposed, it is described
The outer of filter membrane 5 is connected with the air-guiding film 4, and the outer of the air-guiding film 4 is connected with the inner wall of the filter.Institute
The secondary filter film 8 stated is in spherical cap shape, and the secondary filter film 8 is with a filter membrane 5 and air-guiding film 4 same
Place is connected.The secondary filter film 8 is nanoparticle filter membrane.
In use, medical fluid is entered in upper filter chamber 2 by upper conduit 1, medicinal liquid osmosis is by entering institute after a filter membrane 5
In the range of stating the encirclement of secondary filter film 8, secondary filter film 8 is then penetrated through again, into lower filter chamber 6, under
Conduit 7 flows out.
Compared with prior art, the liquid medicine filter provided in the present embodiment mainly has following advantage:
