Abstract
The utility model discloses an air filter of a disposable infusion apparatus. The air filter is characterized in that two layers of air filter paper (2) are arranged in a funnel-shaped plastic shell (1), a layer of activated carbon (3) with poisonous gas and germ adsorption performance is arranged between the two layers of air filter paper (2), and a plastic pressing cap (4) is plugged in an upper opening of the funnel-shaped plastic shell (1). The air filter has the advantage that harmful gas and germs can be truly effectively prevented from entering infused liquid medicine along with air to pollute the liquid medicine, so that side effects of infusion can be reduced.
Description
Technical field
This utility model belongs to medical instruments field, relates to a kind of air filter of disposable transfusion device.
Technical background
The air filter of existing disposable transfusion device, be to remove airborne microgranule by one deck filter paper filtering, but can not cross the airborne harmful gas of elimination and pathogenic bacteria.In recent years, airborne harmful gas is more and more, and SARS, influenza, bird flu etc. be take air and emerged in an endless stream as vector-borne disease virus pathogenic bacteria, in the time of when these poisones or pathogenic bacteria enter into the body that transfusion flows to Healthy People with air in, can cause the transfusion side effect, even catch an illness.For reducing the side effect of transfusion, this utility model has designed a kind of air filter of new disposable transfusion device, and it not only can cross the airborne microgranule of elimination, and can also effectively cross the airborne toxic and harmful of elimination and pathogenic bacteria.
The utility model content
The air filter of this transfusion device is to load onto two-layer air paper in the infundibulate cabinet, and the active carbon that one deck has absorption harmful gas and pathogenic bacteria is housed between two-layer air paper, the pressure cap of ventilation in the middle of funnel plug one suitable for reading.
The accompanying drawing explanation
Accompanying drawing is the sectional structure schematic diagram of the air filter of this utility model disposable transfusion device.
In accompanying drawing: 1, infundibulate cabinet; 2, filter paper; 3, activated carbon; 4, plastics pressure cap.
The specific embodiment
The concrete structure of the air filter of this disposable transfusion device is: load onto two layers of filter paper 2 in infundibulate cabinet 1, the activated carbon 3 of pathogenic bacteria performance that dress one deck has the absorption harmful gas between two layers of filter paper, plastic funnel 1 plug suitable for reading in the middle of the plastics pressure cap 4 of ventilation.
Concrete service condition
When transfusion, air and airborne microgranule, harmful gas, the passage of pathogenic bacteria from plastics pressure cap 4 pass through, when crossing ground floor filter paper 2, filter paper 2 is crossed the airborne microgranule of elimination, by activated carbon 3 time, the airborne toxic and harmful of activated carbon adsorption and pathogenic bacteria, filter paper 2 filtration of active charcoal 3 microgranules when crossing second layer filter paper 2, the air entered like this in infusion bottle is just clean.
The charcoal filter of the canister respirator that the air filter of this utility model disposable transfusion device is exactly a micro in fact.
Use this filter, really effectively can prevent that harmful gas and pathogenic bacteria from entering in transfusion with air, pollute medicinal liquid, reduce the transfusion side effect.
Claims (1)
1. the air filter of disposable transfusion device, identical with the air filter profile of the disposable transfusion device of current use, it is characterized in that: load onto two-layer air paper (2) in infundibulate cabinet (1), the activated carbon (3) that dress one deck has absorption toxic and harmful and pathogenic bacteria performance between two-layer air paper (2), at the plug suitable for reading one plastics pressure cap (4) of infundibulate cabinet (1).
