Abstract
The utility model relates to a final filtration device for a syringe, comprising a casing, wherein, the casing is provided with a half partition wall, one side of the half partition wall is provided with a filter membrane, and the upper part of the casing is provided with a steam chamber. When the utility model is used, when the physic liquor passes through the filter membrane, as the physic liquor reversely flows upwards, the filtered micro-particles can not be attached to the filter membrane, and the filter membrane can not be blocked easily. The flow speed and the flow quantity of the physic liquor keep unchanged in the process of the infusion; meanwhile, the utility model is provided with the steam chamber, the steam bubbles in the physic liquor can be stored in the steam chamber and can not be infused into the human body, and the use is convenient and safe.
Description
This utility model belongs to a kind of filter for transfusion.
At present, the liquid medicine filter of transfusion usefulness is in transfusion, microgranule in the medicinal liquid is attached directly on the filter membrane, filter membrane easily stops up, the flow velocity and the flow of medicinal liquid are changed, and this filter can not get rid of the steam bubble in the medicinal liquid, the nurse must get rid of steam bubble earlier before transfusion, waste part medicinal liquid uses very inconvenient in the operation.
The purpose of this utility model is a kind of steam bubble that can get rid of in the medicinal liquid of design, filtering microgranule is separated with filter membrane make the not susceptible to plugging liquid medicine filter of filter membrane.
This utility model comprises housing, is respectively equipped with input port and delivery outlet at the housing two ends, and lid is arranged at housing top, and base is arranged at the bottom, and its feature is, is provided with half partition wall in housing, and a side of half partition wall is equipped with filter membrane, and the spatial top that housing and lid constitute is steam chest.
Operation principle of the present utility model is: when need enter this filter to patient infusion from the input port, at first impact half partition wall, go up instead then and filter by filter membrane, like this, filtering microgranule is difficult for attached on the filter membrane, medicinal liquid enters steam chest after by filter membrane, and at this moment a small amount of steam bubble in the medicinal liquid is just stayed in the steam chest, and medicinal liquid continues to enter in the human body by delivery outlet forward.
This utility model has following advantage: (1) because this utility model has steam chest, so a small amount of steam bubble in when transfusion medicinal liquid can deposit in the steam chest, avoids steam bubble to enter human body, and is safe and convenient to use; (2),, be difficult for attached on the filter membrane and the obstruction filter membrane, thereby the flow velocity and the flow of medicinal liquid do not change so filtering microgranule and filter membrane are easily separated because medicinal liquid is upwards anti-by filter membrane.
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
In the present embodiment, medicinal liquid steam bubble medical filtration formula ultimate filter, comprise housing (1), be respectively equipped with input port (2) and delivery outlet (3) at the two ends of housing (1), lid (4) is arranged above the housing (1), base (8) is arranged below, be characterized in housing (1), being provided with half partition wall (5), one side of half partition wall (5) is equipped with filter membrane (6), and the spatial top that housing (1) and lid (4) constitute is steam chest (7).
During use, this utility model is inserted the terminal of transfusion device, lie on the human body, (2) enter this filter to medicinal liquid from the input port, at first impact half partition wall (5), upwards instead filter then by filter membrane (6), like this, filtering microgranule is difficult for attached on the filter membrane (6), and medicinal liquid enters steam chest (7) after by filter membrane (6), at this moment a small amount of steam bubble in the medicinal liquid is just stayed in the steam chest (7), and medicinal liquid continues to enter in the human body by delivery outlet (3) forward.
Claims (1)
- Medicinal liquid steam bubble medical filtration formula ultimate filter, comprise housing (1), the two ends of housing (1) are respectively equipped with input port (2) and delivery outlet (3), lid (4) is arranged above the housing (1), base (8) is arranged below, it is characterized in that being provided with in housing (1) half partition wall (5), the spatial top that a side of half partition wall (5) is equipped with filter membrane (6), housing (1) and lid (4) formation is air chamber (7).
