Enema dispenser
View Patent ↗An enema includes a liquid in a dispenser having a bottle, a nozzle attached to the bottle, and a valve. The valve may be a membrane having a slit and a thickness of at most 0.90 mm. The valve may be attached to the bottle or it may be attached to the nozzle. The enema can be administered more easily, with a lower amount of force. A method of bowel cleansing includes inserting the enema into a rectum and applying a compression force to the enema bottle.
1. An enema, comprising:
a bottle comprising a bottle opening;
a nozzle, attached to the bottle at the bottle opening, and comprising a distal opening;
a valve comprising a single slit, attached to the nozzle;
a protective shield on the nozzle;
a liquid in the bottle;
wherein at least a portion of the liquid can be dispensed through the distal opening when the bottle is compressed with a force of at most 15 Newtons;
the valve is sterile, and
the valve has a thickness from 0.05 to 0.90 mm.
2. The enema of claim 1 , wherein at least a portion of the liquid can be dispensed through the distal opening when the bottle is compressed with a force of at most 10 Newtons.
3. The enema of claim 1 , wherein at least a portion of the liquid can be dispensed through the distal opening when the bottle is compressed with a force of at most 5 Newtons.
4. The enema of claim 1 , wherein the liquid comprises a unit dose of an aqueous mixture comprising dibasic sodium phosphate and monobasic sodium phosphate.
5. The enema of claim 4 , wherein the unit dose comprises from 6.84 to 7.56 grams dibasic sodium phosphate and from 18.24 to 20.16 grams monobasic sodium phosphate.
6. The enema of claim 5 , wherein at least 50% of the unit dose can be dispensed from the distal opening when the bottle is compressed with a force of at most 80 Newtons.
7. The enema of claim 5 , wherein at least 50% of the unit dose can be dispensed from the distal opening when the bottle is compressed with a force of at most 60 Newtons.
8. The enema of claim 5 , wherein at least 50% of the unit dose can be dispensed from the distal opening when the bottle is compressed with a force of at most 40 Newtons.
9. The enema of claim 4 , wherein the unit dose comprises from 3.42 to 3.78 grams dibasic sodium phosphate and from 9.12 to 10.08 grams monobasic sodium phosphate.
10. The enema of claim 9 , wherein at least 50% of the unit dose can be dispensed from the distal opening when the bottle is compressed with a force of at most 80 Newtons.
11. The enema of claim 9 , wherein at least 50% of the unit dose can be dispensed from the distal opening when the bottle is compressed with a force of at most 60 Newtons.
12. The enema of claim 1 , wherein the liquid comprises a unit dose of mineral oil.
13. The enema of claim 12 , wherein at least 50% of the unit dose can be dispensed from the distal opening when the bottle is compressed with a force of at most 80 Newtons.
14. The enema of claim 1 , wherein liquid flow from the distal opening into the bottle is prevented.
15. The enema of claim 1 , wherein the bottle comprises a flexible material; and wherein the flexible material is sterile.
16. An enema, comprising:
a bottle comprising a bottle opening;
a nozzle, attached to the bottle at the bottle opening, and comprising a distal opening;
a valve comprising a single slit, attached to the nozzle;
a protective shield on the nozzle;
at least a unit dose of a liquid, in the bottle;
wherein at least 50% of the unit dose can be dispensed through the distal opening when the bottle is compressed with a force of at most 60 Newtons;
the valve is sterile, and
the valve has a thickness from 0.05 to 0.90 mm.
17. The enema of claim 16 , wherein at least 50 % of the unit dose can be dispensed from the distal opening upon application of a compression force to the bottle of at most 55 Newtons.
18. The enema of claim 16 , wherein at least 50% of the unit dose can be dispensed from the distal opening upon application of a compression force to the bottle of at most 40 Newtons.
19. The enema of claim 16 , wherein the liquid comprises a composition selected from the group consisting of an aqueous mixture comprising dibasic sodium phosphate and monobasic sodium phosphate, and an aqueous mixture comprising bisacodyl.
20. The enema of claim 16 , wherein liquid flow from the distal opening into the bottle is prevented.
21. The enema of claim 16 , wherein the bottle comprises a flexible material; and wherein the flexible material is sterile.
