Enema device, and a delivery container for use in said enema device
The present invention relates to an enema device comprising a delivery container arranged for accommodating an enema and an applicator nozzle for dispersing the enema, and wherein the delivery container is arranged as a hand held pump and for remaining in an at least partly compressed configuration when the user releases the pressure on said delivery container during use. Thereby is provided a simple, inexpensive and essentially maintenance free enema device which can be used for self-administrating of an enema.
1 . An enema device comprising a flexible delivery container arranged for accommodating an enema and an applicator nozzle for dispersing the enema, and wherein the delivery container is arranged as a hand held pump and for remaining in an at least partly compressed configuration when a user releases pressure on said delivery container during use, wherein the enema device comprises a closure member, comprising a first closure part arranged for being attached to the delivery container, and a second closure part arranged for being separated from or connected to the first closure part, and wherein the second closure part comprises a female coupling part arranged for releasably connecting a male coupling part of the applicator nozzle to the enema device and for providing a fluid communication between the applicator nozzle and the delivery container.
2 . The enema device according to claim 1 , wherein the closure member is a hinged lid.
3 . The enema device according to claim 1 , wherein a first opening is provided into the delivery container when the second closure part is separated from the first closure part, and wherein said first opening constitutes at least 50% of a cross-section taken at the top section of the delivery container.
4 . A delivery container as defined in claim 1 , arranged for being connected to an application nozzle via a closure member.
5 . The enema device according to claim 1 , wherein a cross-section of said delivery container has the shape of an oval.
6 . The enema device according to claim 1 , wherein the delivery container comprises a bottom section with a first cross-section in the shape of an oval, and a top section with a second cross-section in the shape of an oval, and wherein the minor and/or the major axis of the first cross-section is larger than the respective minor and/or the major axis of the second cross-section.
7 . The enema device according to claim 6 , wherein the ratio of the minor axis to the major axis of said oval is ⅔ or lower.
8 . The enema device according to claim 6 , wherein the bottom section tapers towards the top section, thereby providing a smooth transition between the two sections.
9 . The enema device according to claim 1 , wherein the enema device comprises a non-return valve arranged for preventing fluids from being drawn into the delivery container during operation.
10 . The enema device according to claim 1 , wherein the delivery container is made of a resilient deformable material with a memory.
11 . The enema device according to claim 1 , wherein the delivery container is arranged for expelling at least 80-vol % of the enema accommodated in the delivery container.
12 . The enema device according to claim 1 , wherein the delivery container comprises one or more compression zones arranged for providing a controlled compression of said delivery container.
13 . The enema device according to claim 12 , wherein the one or more compression zones constitute less than 50% of the surface area of the delivery container.
14 . The enema device according to claim 12 , wherein the one or more compression zones are provided by adjusting the wall thickness of the delivery container in one or more compression zones.
15 . The enema device according to claim 12 , wherein the one or more compression zones are provided by reducing the wall thickness of the delivery container in one or more bending lines.
16 . The enema device according to claim 12 , wherein the one or more compression zones are provided by providing reinforcement ribs at the inside and/or outside of the delivery container.
17 . The enema device according to claim 12 , wherein the delivery container is made of more than one material, and wherein the respective materials have a different hardness in order to define the one or more compression zones.
18 . The enema device according to claim 1 , wherein the delivery container is arranged for being fully compressed by a force of less than about 150 N.
19 . The enema device according to claim 1 , wherein the delivery container is arranged such that said delivery container will not be compressed before a force of between about 30 N and about 50 N is applied to the sides of said delivery container.
20 . The enema device according to claim 1 , wherein the delivery container is arranged for accommodating at least about 90 ml of enema.
21 . A method of administering an enema using the enema device according to claim 1 , wherein said method comprises the step of: placing the applicator nozzle in a patient's anal opening; squeezing the delivery container thereby allowing the enema to flow out of the applicator nozzle and into the rectum and colon of the patient; alternating applying pressure and releasing said pressure from the delivery container, until the desired dosage of enema or the entire enema content has been expelled from the delivery container; removing the applicator nozzle from the patient's anal opening; wherein the delivery container will remain in an at least partly compressed configuration when the user releases the pressure on said delivery container.
22 . A method according to claim 21 , wherein an effective dosage of enema can be administered without required reloading of the delivery container.
23 . A method according to claim 21 , wherein air and liquid is prevented from being drawn into the delivery container when the user releases the pressure on the delivery container.
