Claims
- 1. A disposable molded all plastic sanitary bed pan comprising a bowl having a seat at an upper edge of said bowl, and a texture formed on a surface of that portion of said seat which comes into contact with the skin of a patient, said texture having interconnected depressions forming communicating passageways for allowing an escape of air through said interconnected depressions at an interface between patient and seat, whereby said bed pan is much less likely to cling and stick to said patient.
- 2. An all plastic, molded bedpan having a bowl with a modified oval horizontal cross section, said bowl being higher in a front than in a back, a flange extending from an upper edge of said bowl to form a seat on said bowl , said flange having a generally rounded upper surface at the back of said bowl, said rounded upper surface gradually changing to a steeper drainage surface at the front of said bowl, and a strengthening member at an unattached peripheral edge of said flange, said upper surface of said flange having a texture with mutually interconnected depressions which prevent surface tension and which provide air passageways at an interface between a patient and said flange so that air may move through said interconnected depressions in said texture in order to prevent said bed pan from sticking to said patient.
- 3. The bedpan of claim 1 or 2 wherein an average of said depressions is in the range of about 0.002-0.005 of an inch deep.
- 4. The bedpan of claim 3 wherein side walls of said depression have a draft angle in the order of at least 2.degree.-5.degree..
- 5. The bedpan of claim 1 or 2 wherein on average said depressions are about 0.003 of an inch deep.
- 6. The bedpan of claim 4 wherein side walls of said depression have a draft angle in the order of at least 2.degree.-5.degree..
- 7. The bedpan of claim 1 or 2 wherein the side walls of said depression have a draft angle in the order of at least 2.degree.-5.degree..
- 8. The bedpan of one of the claims 1 or 2 wherein side walls of said depression have a draft angle of at least substantially 4.5.degree..
- 9. The bedpan of one of the claims 1 or 2 wherein said seat having a modified oval opening formed therein,said modified oval has two areas in front which tend to form corners between long sides and a front side of said oval, and said texture continues at least into said front corners.
- 10. The bed pan of claim 1 wherein said seat is a flange which is outwardly directed from an upper edge of said bowl.
- 11. The bed pan of one of the claims 1 or 2 wherein said seat is a flange extending outwardly from said bowl.
- 12. The bed pan of one of the claims 1 or 2 wherein said seat is a flange extending from an upper edge of the bowl outwardly to a strengthening outside wall surrounding said bowl.
- 13. The bed pan of claim 2 wherein said flange is outwardly directed from an upper edge of said bowl.
