Abstract
A device for introducing aqueous compositions, especially those containing medicaments, in the form of a foam to a body cavity such as the colon or vagina, comprising a plastic container having a resilient deformable body portion, a dispersing end adapted to engage with the opening of the body cavity and a second end adapted to engage with a one-way valve assembly. When the container is partially filled with a foamable composition and a one-way valve assembly is attached foam may be expelled from the dispensing end into the body opening by squeezing the container body and on releasing the squeezing action air enters through the one-way valve assembly so that the container resumes its original shape ready for a further cycle of squeezing and reinflation.
Claims7
An improved enema device of the type including a container having a resilient, deformable body portion defining an enclosed space, the improvement comprising:
- a. a first end having a first frangible closure, said first end having means for admitting air from the exterior of said body portion into said enclosed space and for restraining flow of container contents out of said enclosed space to the exterior of said body portion, said admitting and restraining means including a one-way air inlet valve;
- b. a second end having means for selectively providing, prior to use, an open dispensing applicator shaped for non-traumatic insertion into an orifice in a body cavity, said providing means including a second frangible closure for exposing said enclosed space;
- c. said second end also being shaped to make sealing contact with respect to the orifice in the body cavity.
A container for use in administering a foam enema, the container comprising:
- a. a wall defining a completely hermetically sealed container enclosing an interior space, said container including a resilient deformable body portion and being partially filled with a foamable substance;
- b. means for converting one end of said completely sealed container into and open dispensing applicator shaped for non-traumatic insertion into and orifice in a body cavity and for converting said container into a device by which foam may be continuously pumped from the container by repeated squeezing and release of the resilient deformable body portion, said converting means including one frangible portion at said one end of said container for providing access to said interior space and another frangible portion at said other end, said other end having a coupling for accepting a one-way air inlet valve;
- c. said one end being shaped to make sealing contact with respect to the orifice in the body cavity.
