ABSTRACT:
FIELD OF THE INVENTION
This invention relates to an apparatus for collecting waste odors. More particularly this invention relates to a portable apparatus which works in conjunction with an existing ceiling exhaust intake to more directly and selectively intake waste odor emanating either from a bed pan, or from a toilet having a conventionally mounted hinged toilet seat.
BACKGROUND OF THE INVENTION
There is a real unsatisfied need in hospitals and nursing homes for an apparatus for collecting waste odors emanating from bed pans. These odors are unpleasant for both patients and staff. Although these waste odors are not common with most patients, their incidence with particular patients is common and severe. What is needed is a portable apparatus which could be moved from room to room where needed. Such an apparatus should be able to be used in existing conventionally designed hospital and nursing home facilities.
There is also a real unsatisfied need particularly in hospitals and nursing homes for a portable apparatus which could be added to existing toilet facilities to better and more directly ventilate odors from those toilets. It would be particularly desirable if such an apparatus could be used in conjunction with an existing toilet having a conventionally mounted seat. Most apparatuses used to better and more directly ventilate odors from existing toilets mandate that the seat of the toilet be raised on its hinges. Not only does this require a relatively substantial and expensive intake ring which is positioned beneath the toilet seat (such a ring must support a full user's weight), but it also requires the mounting of the ring and the consequent sub-optimal height of the toilet seat.
OBJECTS OF THE INVENTION
It is an object of this invention to disclose an apparatus for collecting waste odors emanating from bed pans. It is an object of this invention to disclose a portable apparatus which could be moved by staff, from room to room in hospitals and nursing homes, without any need for installation tools to where needed. It is an object of this invention to disclose a portable apparatus which could be able to be used in existing conventionally designed hospital and nursing home facilities. It is yet a further object of this invention to disclose a portable apparatus which could be added to existing toilet facilities to better and more directly ventilate odors from those toilets. It is a final object of this invention to disclose an apparatus which can better and more directly ventilate odors from existing toilets without requiring that the seat of the toilet be raised on its hinges. Such an apparatus would not only be relatively inexpensive but really portable. It also could be used on existing toilets without changing the seat height to a sub optimal height.
One aspect of this invention provides for a portable apparatus which works in conjunction with an existing ceiling exhaust intake to more directly and selectively intake waste odor emanating either from a bed pan, or from a toilet having a conventionally mounted hinged toilet seat. The waste odor collection apparatus comprises: an upright tube having an upper end portion, a central portion adapted to receive a flexible hose, and a lower portion adapted to seat on a supporting surface; a hood carried by and above the upper portion of the upright tube is adapted to peripherally surround and cover the exhaust intake on the ceiling. A first flexible hose having a feed end portion is adapted to removably attach to the central portion of the upright tube. The hose has a collection end which may be routed proximate to a source of waste odor.
Another aspect of this apparatus comprises an odor collection wand which is adapted to be positioned beneath a rear portion between the hinges on a conventionally mounted toilet seat on a toilet. It is used in conjunction with a flexible hose connected to an exhaust intake. The odor collection wand comprises: a similarly shaped upper and lower L shaped members, each member generally having interior and exterior L shaped peripheral edges. The members are connected and spaced along their interior and exterior peripheral L shaped edges in a generally planar orientation by a continuous edge spacer. The members are adapted to intake odors on one end between their interior and exterior L shaped edges, and adapted to receive the flexible vacuum hose on their opposite end portion between their interior and exterior L shaped edges. This enables an intake end portion of the wand, without increasing the conventional spacing between the toilet seat and the toilet, to be inserted above the toilet bowl, beneath the toilet seat and between the hinges on the toilet, so that when the flexible vacuum hose is connected thereto air will be drawn therein from inside the toilet bowl. In a preferred aspect of this invention the edge spacer allows an intake end portion of the two L shaped members to move together if so squeezed together between the hinged toilet seat and the toilet bowl.
Various other objects, advantages and features of this invention will become apparent to those skilled in the art from the following description in conjunction with the accompanying drawings.
