ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a chair with a toilet sink, and in particular, to a chair with a toilet sink having a lid which can be easily removed and replaced.
2. Description of the Prior Art
To help physically challenged or elderly persons, or persons having difficulty in using a toilet on their own, wealthy households take advantage of the availability of nurses. Since employing nurses-can be difficult or expensive, various companies have introduced chairs that are designed for conveniently answering nature's call, to be used by a patient who leaves the bed and has a certain degree of mobility.
One example of such chairs is illustrated in
FIG. 6
, which shows a chair
90
having a seat plate
91
with a hole
92
provided therein. A toilet sink
93
is mounted below the hole
92
for collecting the excreta and urine. Although this design provides a certain degree of convenience, the existence of the uncovered hole
92
means that the patient will not be able to stay seated on the seat plate
91
for an extended time.
FIG. 7
illustrates another example. To provide more comfortable seating, a cushion or a lid
94
is placed on the seat plate
91
, which covers the hole
92
so that the patient can sit comfortably on the cushion
94
. Although the chair shown in
FIG. 7
allows the patient to answer nature's call as well as to move around comfortably, it suffers from the following shortcomings:
1. When the patient wants to relieve himself or herself, a nurse has to help her or him up, open the lid
94
, and carry the patient back on the chair.
2. After usage, the nurse has to lift up the patient again and close the lid
94
to bring the patient back onto the chair.
3. If the patient is an adult person, her or his body is relatively heavy and may not be easy to move. In practice, it is difficult for other persons to lift the patient up from the lid
94
and to put her or him back on the lid
94
, as described above.
4. If the lid
94
is not closed, the patient will sit directly on the seat plate
91
, which is both uncomfortable and impairs blood circulation in the patient's body.
Thus, there remains a need for a seat that can be used by a patient to answer the call of nature, which avoids the drawbacks set forth above.
SUMMARY OF THE DISCLOSURE
It is an object of the present invention to provide a chair with a toilet sink having a lid which a patient is able to open on her or his own, or with the assistance of a nurse, without having to leave the chair.
