Abstract

Apparatus for protecting a mattress from body-liquids and collecting the body-liquids which includes a flexible liquid-impervious laminated mattress pad within the layers of which is a tube accessed from the upper surface of the pad through holes and also continuous suction means for drawing off through the holes and tube any body liquids deposited on the upper surface of the pad.

Claims

1. For use with body-liquid collecting and mattress protecting apparatus, a flexible liquid-impervious laminated mattress pad comprising

(a) an extended central flexible tube sealed at one end,

(b) upper and lower liquid-impervious inner sheets joined together and enclosing that tube end portion which is sealed,

(c) upper and lower liquid-impervious outer sheets joined together and enclosing the respective inner sheets and a portion of the tube not enclosed within the inner sheets,

(d) the lower outer sheet defining an aperture through which the remainder of the tube extends, and

(e) a plurality of aligned body-liquid collecting holes through the upper outer and upper inner sheets and the wall of the tube end portion enclosed by the inner sheets.

2. A laminated mattress pad according to claim 1 wherein the upper inner sheet is disposed substantially straight across the enclosed tube end portion and the lower inner sheet is fitted over and around said tube end portion.

3. A laminated mattress pad according to claim 1 wherein the upper and lower inner sheets match in size and shape and the upper and lower outer sheets match in size and shape and are larger than the inner sheets.

4. A laminated mattress pad according to claim 1 wherein the upper and lower inner sheets are joined together by a substantially continuous layer of adhesive and the upper and lower outer sheets are joined together and to the respective upper and lower inner sheets by respective substantially continuous layers of adhesive.

5. Body-liquid collecting and mattress protecting apparatus comprising

(a) a flexible liquid-impervious laminated mattress pad comprising

i. an extended central flexible tube sealed at one end,

ii. upper and lower liquid-impervious inner sheets joined together and enclosed that tube end portion which is sealed,

iii. upper and lower liquid-impervious outer sheets joined together and enclosing the respective inner sheets and a portion of the tube not enclosed within the inner sheets,

iv. the lower outer sheet defining an aperture through which the remainder of the tube extends, and

v. a plurality of aligned body-liquid collecting holes through the upper outer and upper inner sheets and the wall of the tube end portion enclosed by the inner sheets;

and

(b) suctioning means for applying a vacuum through said tube and holes to draw off and collect any body-liquids deposited on the upper outer sheet of the mattress pad.

6. Body-liquid collecting and mattress protecting apparatus according to claim 5 wherein the upper inner sheet is disposed substantially straight across the enclosed tube end portion and the lower inner sheet is fitted over and around said tube end portion.

7. Body-liquid collecting and mattress protecting apparatus according to claim 5 wherein the upper and lower inner sheets match in size and shape and the upper and lower outer sheets match in size and shape and are larger than the inner sheets.

8. Body-liquid collecting and mattress portecting apparatus according to claim 7 wherein the suctioning means includes a sealed container with which said tube communicates, a pneumatic line also communicating with said container and a continuous suction pump operatively connected to said pneumatic line.

9. Body-liquid collecting and mattress protecting apparatus according to claim 8 wherein dehydrator means are located in the pneumatic line between the container and the suction pump.

10. Body-liquid collecting and mattress protecting apparatus according to claim 5 wherein the upper and lower inner sheets are joined together by a substantially continuous layer of adhesive and the upper and lower outer sheets are joined to one another and to the respective upper and lower inner sheets by respective substantially continuous layers of adhesive.

11. Body-liquid collecting and mattress protecting apparatus according to claim 5 wherein the suctioning means includes a sealed container with which said tube communicates, a pneumatic line also communicating with said container and a continuous suction pump operatively connected to said pneumatic line.

12. Body-liquid collecting and mattress protecting apparatus according to claim 11 wherein dehydrator means are located in the pneumatic line between the container and the suction pump.

13. Body-liquid collecting and mattress protecting apparatus comprising

(a) A flexible liquid-impervious laminated mattress pad comprising

i. an extended central flexible tube sealed at one end,

ii. matching rectangular upper and lower liquid-impervious inner sheets joined by a substantially continuous layer of adhesive and enclosing that tube end portion which is sealed,

iii. the upper inner sheet being disposed substantially straight across the enclosed tube end portion and the lower inner sheet being fitted over and around said tube end portion,

iv. matching rectangular upper and lower liquidimpervious outer sheets of a length and width greater than the inner sheets joined together and to the respective upper and lower inner sheets by respective substantially continuous layers of adhesive and enclosing the inner sheets and a portion of the tube not enclosed within the ineer sheets,

iv. the lower outer sheet defining an aperture through which the remainder of the tube extends, and

v. a plurality of aligned body-liquid collecting holes through the upper outer and upper inner sheets and the wall of the tube end portion enclosed by the inner sheets;

and

(b) suctioning means for applying a vacuum through said tube and holes to draw off and collect any body-liquids deposited on the upper outer sheet of the mattress pad.
