Filtration members are supported by some plate bodys, because plate body quantity is relatively more, in the same of stable support filtration members
When, gas smoothly can flow in filter chamber.
In above-mentioned veress needle filter, the line between the import and outlet is parallel with plate body side.
Such structure is easy to gas smooth outflow.
In above-mentioned veress needle filter, the plate body outer end has the transition part seamlessly transitted.
In above-mentioned veress needle filter, described transition part is the chamfering at plate body outer end.
In above-mentioned veress needle filter, described transition part is the fillet at plate body outer end.
The setting of transition part avoids causing scratch to filtration members.
In above-mentioned veress needle filter, described filtration members are filter paper in the form of sheets, and above-mentioned filter paper will filter
Chamber is divided into two adjacent individual cavities of left and right.
In above-mentioned veress needle filter, in addition to two pieces of discoid supporting plates, above-mentioned two pieces of supporting plates are pressed
Between upper lid and lower cover and above-mentioned filter paper is pressed between two supporting plates.
In above-mentioned veress needle filter, described supporting plate is the air permeable plate with some air-vents.
In above-mentioned veress needle filter, described supporting plate is the air permeable plate of lattice-shaped.
Supporting plate has two effects, first, being supported to filter paper；Secondly, gas can be made to smoothly pass over supporting plate.
Compared with prior art, this veress needle filter can be supported stably due to filtration members, is filtered in use
Part can stablize filtering gas, and its stability is higher.
Meanwhile plate body is uniformly arranged, and plate body, in filter chamber, therefore, its structure is compact, has very
High practical value.

Embodiment
As depicted in figs. 1 and 2, this veress needle filter includes upper lid 1, lower cover 2 and filtration members, and the above-mentioned upper inner side of lid 1 has
Have a recessed cavity one, the upper outside of lid 1 has an import communicated with cavity one, the inner side of lower cover 2 with recessed cavity two,
The outside of lower cover 2 has an outlet communicated with cavity two, and the above-mentioned upper inner side of lid 1 is interlocked with the inner side of lower cover 2 and shape therebetween
Into the filter chamber 3 of closing, above-mentioned filtration members are in the form of sheets and filtration members are located in filter chamber 3, at above-mentioned cavity one and cavity two
