Device to deliver a predetermined amount of a substance to a natural orifice of the body

A multi-use device for delivering a predetermined amount of at least one substance to a body orifice of a subject, said device characterized by a main longitudinal axis;

• said device comprising:
• a. a container for containing said at least one substance;
• b. a delivery end for placement in proximity to said orifice, said delivery end being in fluid communication with said container;
• c. a valve mechanically connectable to said container, characterized by at least two configurations:
• (i) an ACTIVE CONFIGURATION in which said valve enables delivery of predetermined amount of said substance from said container to said body orifice via said delivery end;
• and, (ii) an INACTIVE CONFIGURATION, in which said valve prevents delivery of said predetermined amount of said substance from said container to said body orifice;
• said valve comprising at least one hollow element in communication with said fluid tight chamber and said container;
• said hollow element comprising at least one opening, being sealed with at least one sealing element, when said valve is in said INACTIVE CONFIGURATION;
• wherein the at least one hollow element is disposed to contact and be positionally limited by a movable spherical element disposed within the delivery end, the spherical element being disposed radially outward from the at least one hollow element, and wherein displacement of the spherical element from a first area to a second area within the delivery end facilitates piercing by the at least one hollow element of said container, the second area being larger than the first area;
• d. a fluid tight chamber adapted to contain predetermined amount of pressurized gas at a predetermined pressure;
• wherein once said valve is reconfigured from said INACTIVE CONFIGURATION to said ACTIVE CONFIGURATION, said at least one sealing is removed from said at least one opening;
• further wherein said pressurized gas, once said valve is reconfigured from said INACTIVE CONFIGURATION to said ACTIVE CONFIGURATION, is adapted to exit said fluid tight chamber, enter said hollow element and therefrom, through said at least one opening, into said container and entrain said substance and deliver the same via said delivery end to a predetermined site of delivery within said body orifice.

A method for dispensing a flowable substance, comprising steps of:

• a. providing a multi-use device for delivering a predetermined amount of at least one substance to a body orifice of a subject, said device characterized by a main longitudinal axis;
• said device comprising:
• i. a container for containing said at least one substance;
• ii. a delivery end for placement in proximity to said orifice, said delivery end being in fluid communication with said container;
• iii. a valve mechanically connectable to said container, characterized by at least two configurations:
• (i) an ACTIVE CONFIGURATION in which said valve enables delivery of predetermined amount of said substance from said container to said body orifice via said delivery end;
• and, (ii) an INACTIVE CONFIGURATION, in which said valve prevents delivery of said predetermined amount of said substance from said container to said body orifice;
• iv. a fluid tight chamber adapted to contain predetermined amount of pressurized gas at a predetermined pressure;
• V. at least one hollow piercing needle in communication with said valve, said fluid tight chamber and said container;
• said hollow piercing needle comprises at least one sharp end, adapted to pierce said container, and comprising at least one opening, the at least one hollow piercing needle being disposed to contact and be positionally limited by a movable spherical element disposed within the delivery end, the spherical element being disposed radially outward from the at least one hollow piercing needle, and wherein displacement of the spherical element from a first area to a second area within the delivery end facilitates piercing by the at least one hollow piercing needle of said container, the second area being larger than the first area;
• b. emplacing said substance in said chamber;
• c. placing said valve in said inactive configuration;
• d. pressurizing said fluid-tight chamber with said gas to said predetermined pressure;
• e. reconfiguring said valve from said INACTIVE CONFIGURATION to said ACTIVE CONFIGURATION;
• thereby piercing said container;
• thereby enabling said pressurized gas to exit said fluid tight chamber, enter said hollow piercing needle and therefrom, through said at least one opening, into said container and entraining said substance and delivering the same via said delivery end to a predetermined site of delivery within said body.
