Abstract
The utility model discloses a medicinal liquid filter which is composed of an upper casing with a liquid inlet pipe, a filtering film sheet, a lower casing with a liquid outlet pipe, etc., wherein the upper casing and the lower casing are mutually parallel and provided with inner cavities; the direction that medicinal liquid passes through the filtering film sheet is perpendicular to the direction that the medicinal liquid flows from the liquid inlet end of a casing body to the liquid outlet end; an air hole is arranged on the upper casing, and the film sheet is arranged at the air hole on the inner wall of the casing body. Thus, the medicinal liquid filter of the utility model has the characteristics of simple structure, little resistance when the medicinal liquid flows, etc.
Description
Technical field
This utility model relates to a kind of filter, especially a kind of liquid medicine filter.
Background technology
Present filter used when infusing to the people, be mounted in the disposable transfusion device terminal, in order to the above particulate matter of 3-5 μ in the filtering medicinal liquid, but this filter often the liquid in-out mouth in the same side direction, flow direction repeatedly alters course, and the out-of-date resistance that is subjected to of flow of liquid is big; Present filter has gas in tube for transfusion when transfusion, will get rid of ducted gas in advance and could infuse, and makes that the transfusion aerofluxus is not smooth, but does not have a kind of filter can effectively remove this phenomenon.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, can get rid of ducted gas, simple in structure and the little liquid medicine filter of resistance that transfusion is subjected to the time when a kind of the transfusion is provided automatically.
Liquid medicine filter of the present utility model comprises upper casing, filtration membrane, the lower casing of drag-out pipe, described upper casing and the mutual equality of lower casing and the band inner chamber of being with feed tube; Described filtration membrane is between the inner chamber of upper casing and lower casing, make from the flow through medicinal liquid of inner chamber of lower casing of the inner chamber of upper casing and must pass through filtration membrane, and direction and the medicinal liquid of medicinal liquid by described filtration membrane is perpendicular from the direction that the liquid feeding end of housing flows to liquid outlet; The centrage of described feed tube and drain pipe is parallel to each other; Described upper casing, filtration membrane, lower casing is fixedly connected is integral; On the described upper casing air-vent is arranged, described air-vent place and diaphragm is arranged on inner walls, described diaphragm makes the intravital air of shell see through diaphragm and discharges housing, but medicinal liquid can not pass through.
Described can be to link into an integrated entity by ultrasonic bonding between the lower casing upward; Described filtration membrane can be to be connected in the housing of upper casing or lower casing by supersonic welding, in order to make filtration membrane and housing internal chamber wall firm welding, in the housing of described upper casing or lower casing, in order to make filtration membrane and housing internal chamber wall firm welding, on described upper casing or lower casing or both internal chamber walls a rule projection can be arranged, described filtration membrane is welded in above the internal chamber wall of projection and housing.
The diaphragm in described ventilative aperture can be made by nylon hydrophobic membrane material.
According to above-described a kind of liquid medicine filter, have resistance simple in structure, that cost is low, flow of liquid is subjected to when the filter little, can discharge the characteristics such as gas in the tube for transfusion automatically.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
In Fig. 1, a kind of liquid medicine filter comprises liquid medicine filter of the present utility model, comprises upper casing 1, filtration membrane 2, the lower casing 3 of drag-out pipe 5, described upper casing 1 and lower casing 3 mutual equalitys and the band inner chamber of being with feed tube 4; Described filtration membrane 2 is between the inner chamber of upper casing 1 and lower casing 3, make from the flow through medicinal liquid of inner chamber of lower casing 3 of the inner chamber of upper casing 1 and must pass through filtration membrane 2, and direction and the medicinal liquid of medicinal liquid by described filtration membrane 2 is perpendicular from the direction that the liquid feeding end of housing flows to liquid outlet; Described feed tube 4 is parallel to each other with the centrage of drain pipe 5; Described upper casing 1, filtration membrane 2, lower casing 3 are integral by ultrasonic bonding; An air-vent 6 is arranged on the described upper casing 1, described air-vent 6 places and diaphragm 7 is arranged on inner walls, described diaphragm 7 makes the intravital air of shell see through diaphragm 7 and discharges housings, but medicinal liquid can not pass through, and described air-vent 6 is circular.
Claims (6)
