upper surfacebe greater than lower surface pressure, can increase to a certain extent lower liquid speed.
According to the accurate filter described in utility model, it is characterized in that: upper casing, lower casing adopt transparent ABS material to make, air-filtering membrane adopts the PTFE of hydrophobic material to add non-woven fabrics and makes, liquid medicine filtering membrane adopts nucleopore membranes addition polymerization adipose membrane to make, aperture is less than 5 microns, because its pore size filter is little, there is the feature of secondary filter, applicable to critical patient and child.Air-filtering membrane adopts the PTFE of hydrophobic material to add non-woven fabrics or other effects equivalent materials are made, and has the feature of the aerofluxus of blocking water, and on upper casing heat seal duplicature, prevent that heat seal is not in place and cause the situation of leakage to occur.
Accurate filter according to described in utility model, is characterized in that: filter upper casing is furnished with two or more steam vents side by side.Filter upper casing is furnished with two or more steam vents side by side, has strengthened the speed that in conduit, gas is discharged, thereby reaches the feature of fast lower liquid.
The utility model has the advantage of: accurate filter described in the utility model;
This accurate filter has aerofluxus, microporous filter, does not fall the features such as bits.
1, filter upper casing is furnished with two or more steam vents side by side, has strengthened the speed that in conduit, gas is discharged, thereby reaches the feature of fast lower liquid.
2, air-filtering membrane adopts the PTFE of hydrophobic material to add non-woven fabrics or other effects equivalent materials are made, and has the feature of the aerofluxus of blocking water, and on upper casing heat seal duplicature, prevent that heat seal is not in place and cause the situation of leakage to occur.
3, on lower casing, be placed with the Vitex chinensis Mill. identical with liquid medicine filtering membrane gradient, after filter assembling, liquid medicine filtering membrane played a supportive role, liquid flows down the effect that afterwards medicinal liquid is had to leading and reduce impulse force.
4, upper-lower casing registration interface designs has certain gradient, in infusion process, film
upper surfacebe greater than lower surface pressure, can increase to a certain extent lower liquid speed.
5, liquid medicine filtering membrane adopts nucleopore membranes addition polymerization adipose membrane or other effects equivalent materials to make, and aperture is less than 5 microns, because its pore size filter is little, has the feature of secondary filter, applicable to critical patient and child.
