Abstract

Diapers adapted for use in the collection of stool samples from infants are disclosed. Such diapers may include a backsheet comprising an effectively liquid impermeable material, a liquid control structure disposed over the backsheet, and a pass-through port disposed at least partially in the rear portion of the diaper. The diaper may include other features adapted to contain exudates, isolate urine from fecal material following discharge, avoid absorption of liquid components of fecal material and enhance likelihood of collecting a fecal sample that is sufficiently representative of its composition immediately following discharge.

First claim

What is claimed is:

1 . A disposable diaper having a length, a front portion, a rear portion, and a perineal portion between the front and rear portions, the diaper comprising:
a backsheet comprising an effectively liquid impermeable material; a liquid control structure disposed over at least a portion the backsheet; a topsheet disposed over the liquid control structure; a pass-through port disposed at least partially in the rear portion of the diaper; and a sample collection receptacle, wherein the sample collection receptacle is a bag structure comprising an open end and a closed end, and wherein the sample collection receptacle is formed of a liquid impermeable polymeric film.

2 . The diaper of claim 1 , wherein the liquid control structure is disposed only in the front portion of the diaper.

3 . The diaper of claim 1 , comprising left and right standing longitudinal cuffs each extending from the front portion to the rear portion and having a proximal cuff portion, and a free longitudinal cuff distal edge, each longitudinal cuff comprising a longitudinal cuff elastic member proximate the free longitudinal cuff distal edge, the longitudinal cuff elastic member being incorporated into the longitudinal cuff in a pre-strained condition so as to cause material forming the free longitudinal cuff distal edge to gather and extend toward a wearer's skin when the diaper is worn.

4 . The diaper of claim 3 , wherein the longitudinal cuffs comprise effectively liquid impermeable material.

5 . The diaper of claim 3 , wherein the longitudinal cuffs comprise polymeric film.

6 . The diaper of claim 1 , wherein the sample collection receptacle is sealingly affixed to an outer perimeter of the pass-through port.

7 . The diaper of claim 6 , wherein the sample collection receptacle is sealingly affixed to a portion of the backsheet.

8 . A disposable diaper having a length, a front portion, a rear portion, and a perineal portion between the front and rear portions, the disposable diaper comprising:
a backsheet comprising an effectively liquid impermeable material; a liquid control structure disposed over the backsheet; a rear upper layer comprising an effectively liquid impermeable material disposed at least partially in the rear portion of the diaper; a pass-through port disposed at least partially in the rear portion of the diaper; and a sample collection receptacle, wherein the sample collection receptacle is a bag structure comprising an open end and a closed end, and wherein the sample collection receptacle is formed of a liquid impermeable polymeric film.

9 . The diaper of claim 8 , wherein the rear upper layer comprises polymeric film.

10 . The diaper of claim 8 , wherein the liquid control structure is disposed only in the front portion and the perineal portion of the diaper.

11 . The diaper of claim 10 , comprising a front upper layer comprising an effectively liquid permeable material, overlying the liquid control structure in the front portion and the perineal portion of the diaper.

12 . The diaper of claim 8 , wherein the liquid structure is disposed only in the front portion of the diaper.

13 . The diaper of claim 12 , comprising a front upper layer comprising an effectively liquid permeable material, overlying the liquid control structure in the front portion.

14 . The diaper of claim 8 , comprising left and right standing longitudinal cuffs each extending from the front portion to the rear portion and having a proximal cuff portion, and a free longitudinal cuff distal edge, each longitudinal cuff comprising a longitudinal cuff elastic member proximate the free longitudinal cuff distal edge, the longitudinal cuff elastic member being incorporated into the longitudinal cuff in a pre-strained condition so as to cause material forming the free longitudinal cuff distal edge to gather and extend toward a wearer's skin when the diaper is worn.

15 . The diaper of claim 14 , wherein the longitudinal cuffs comprise effectively liquid impermeable material.

16 . The diaper of claim 15 , wherein the longitudinal cuffs comprise polymeric film.

17 . The diaper of claim 8 , wherein the sample collection receptacle is sealingly affixed to an outer perimeter of the pass-through port.

18 . The diaper of claim 17 , wherein the sample collection receptacle is sealingly affixed to a portion of the backsheet.
