Apparatus including a cylindrical body and a nub
An apparatus may include a plunger and a substantially cylindrical body. The substantially cylindrical body may include an end portion having rounded edges and may define a cavity sized to receive the plunger. The substantially cylindrical body may include at least one opening extending from the cavity to an external surface. The at least one opening may a substantially irregular shape. In some embodiments, the at least one opening may extend from the cavity through a nub to the external surface. The nub may have a rounded shape. In some embodiments, the substantially irregular shape may include one of a slit, an oval shape, an elliptical shape, an hourglass shape, a rectangular shape, and a diamond shape. In some embodiments, the opening may be part of a non-cylindrical fluid passage.
1. An apparatus comprising:
a plunger; and
a substantially cylindrical body extending along a longitudinal axis located at a center of the cylindrical body, the cylindrical body configured to penetrate and extend into a vagina and including an end portion defining a distal end of the cylindrical body, the end portion having rounded edges and defining a cavity sized to receive the plunger, the substantially cylindrical body having a length and including an opening on the longitudinal axis and elongated across the longitudinal axis, the opening defining a fluid passage extending from the cavity to an external surface, the opening defining an outer extent at the distal end and at the external surface to dispense a fluid from the apparatus, and the opening having an elongated shape at the outer extent, the elongated shape configured to diffuse a fluid passing through the opening.
2. The apparatus of claim 1 , wherein the elongated shape of the outer extent defines a slit, an oval shape, an elliptical shape, an hourglass shape, a rectangular shape, or a diamond shape.
3. The apparatus of claim 1 , further comprising a nub extending from the end portion for a distance of approximately 4% to 6% of the length of the substantially cylindrical body, wherein the nub has a rounded end defining the external surface.
4. The apparatus of claim 3 , wherein the nub is curved in cross-section and the opening extends through the nub.
5. The apparatus of claim 3 , wherein the substantially cylindrical body and the nub may be formed from a unitary material.
6. The apparatus of claim 1 , wherein the substantially cylindrical body includes a fastener element configured to mate to a corresponding feature of a cap.
7. An apparatus comprising:
a cylindrical body having a proximal end, a distal end, and an elongate portion extending therebetween along a longitudinal axis at a center of the cylindrical body, the distal end and at least a portion of the elongate portion configured to penetrate and extend into a vagina, the distal end having a rounded corner relative to the elongate portion to form a smooth transition from the elongate portion to the distal end, the distal end further including an opening on the longitudinal axis and defining a passage through the distal end, the opening defining an outer extent with an elongated shape across the longitudinal axis; and
a nub disposed on the distal end and extending a distance in a range of 4 mm to 6 mm from the distal end, the nub having a rounded end.
8. The apparatus of claim 7 , wherein the elongated shape of the outer extent defines a slit, an oval shape, an elliptical shape, an hourglass shape, a rectangular shape, or a diamond shape, and wherein the shape is configured to diffuse a fluid passing through the opening.
9. The apparatus of claim 7 , wherein the rounded end of the nub defines one of a substantially hemispherical shape, a substantially annular shape, or a substantially elliptical shape.
10. The apparatus of claim 7 , wherein the nub includes the outer extent of the opening.
11. The apparatus of claim 10 , wherein the body includes a first material and the nub includes a second material that is different from the first material.
12. The apparatus of claim 11 , wherein the passage has a non-cylindrical shape.
13. The apparatus of claim 7 , further comprising a plurality of second openings extending through the distal end of the body.
14. An apparatus comprising:
a tubular element including a body portion defining an internal cavity and having a distal end and a length along a longitudinal axis located at a center of the tubular element, at least a portion of the body portion and the distal end configured to penetrate and extend through a vagina, the distal end including a nub extending from the distal end approximately 4% to 6% of the body portion length and having an opening on the longitudinal axis with a non-circular shape across the longitudinal axis, the opening in fluid communication with the internal cavity via a fluid passage, the tubular element including a substantially smooth exterior surface having rounded edges adjacent the distal end; and
a plunger configured to fit within the cavity.
15. The apparatus of claim 14 , wherein the non-circular shape defines a slit, an oval shape, an elliptical shape, an hourglass shape, a rectangular shape, or a diamond shape.
16. The apparatus of claim 14 , wherein the tubular element defines a portion of a syringe.
