Active Ingredients: Norfloxacin
Maintenance Time and Cost: Related to the above, consider that the larger the number of blinds, the more maintenance time a battery operated motor will need.
I would always recommend mains powered for commercial installations.
In terms of size restrictions - as an example, I have included a table below which shows the recommended maximum sizes for battery operated motors.
The blue area shows where only relatively light weight fabric should be used. Grid 18 has a mesh size sufficiently small to support the smallest granules or particles of therapeutic agent 20. Grid 18 is positioned in tube 12 near its outlet end 16.
The volume of tube 12 between grid 18 and outlet end 16 is sufficient to contain an amount of therapeutic agent 20 corresponding to a unit dose thereof.
Grid 18 and sleeve 26 can be constructed from the same or different materials used for construction of tube 12. A suitable grid mesh can be formed from wire. The grid should be constructed so as to have maximal open area for liquid passage yet able to retain the selected pellets or granules.
The mesh size can range from about 140 mesh to about 10 mesh, more preferably from about 80 mesh to about 10 mesh.
As illustrated in FIG. Delivery device 110 is in the form of a mouthpiece and has an angled grid 18 for supporting particulate or pelletized therapeutic agent 20 in tube 12 having inlet end 14 and outlet end 16.
Inlet end 14 is adapted to receive one end of drinking straw 28 in a fluid tight relationship. It is not critical that tube 12 of delivery devices 10, 110 be of a strictly linear construction. Nor is it critical that tube 12 of delivery device 10, 110 be of constant luminal cross-sectional area throughout its entire length.
Alternate embodiments of this invention are illustrated in FIGS. A unit dose of therapeutic agent 20 is contained in curved tube 212 having liquid inlet end 214 and liquid outlet end 216.
With reference particularly to FIG. The unit dose 210 illustrated in FIGS.
The unit dose 210 of FIG. In the unit dose 210 shown in FIG.
Tube ends sealed as illustrated in FIG. The tube sealing or closure means depicted in each of FIGS. Inlet end 114 of tube 112 is formed to receive sleeve 126 supporting grid 18 with a surface area greater than the luminal cross-sectional area of tube 112.
