Abstract
A disposable human waste management device, such as faecal and urine management devices (10), which are provided with adhesives for attachment of the device to the skin. Such adhesives (20) provide secure attachment and are pleasing to the skin upon application, yet cause no discomfort upon removal. The device may also be used in combination with a disposable diaper.
Claims12
A disposable human waste management device (10) comprising a bag 11, said bag (11) having an aperture and a flange (12) surrounding said aperture (21), said flange (12) having a wearer facing surface (23) and a garment facing surface (22), wherein said wearer facing surface comprises an adhesive (20), wherein said adhesive has:
- (1) a water activity of from 0.4 to 0.9;
- (2) an elastic modulus at 1 rad/s (37° C.) of from 700 to 15,000 Pa;
- (3) an elastic modulus at 100 rad/s (37° C.) of from 2000 to 40,000 Pa;
- (4) a viscous modulus at 1 rad/s (37° C.) of from 450 to 14,000 Pa;
- (5) a viscous modulus at 100 rad/s (37° C.) of from 1000 to 35,000 Pa;
- and
- wherein the viscous modulus is less than the elastic modulus in the frequency range of from 1 to 100 rad/s.
A disposable article comprising:
- (a) a diaper (50);
- and,
- (b) a disposable human waste management device (10);
- wherein said disposable human waste management device further comprises a bag (11), said bag (11) having an aperture and a flange (12) surrounding said aperture (21), said flange (12) having a wearer facing surface (23) and a garment facing surface (22), wherein said wearer facing surface comprises an adhesive (20), wherein said adhesive has:
- (1) a water activity of from 0.4 to 0.9;
- (2) an elastic modulus at 1 rad/s (37° C.) of from 700 to 15,000 Pa;
- (3) an elastic modulus at 100 rad/s (37° C.) of from 2000 to 40,000 Pa;
- (4) a viscous modulus at 1 rad/s (37° C.) of from 450 to 14,000 Pa;
- (5) a viscous modulus at 100 rad/s (37° C.) of from 1000 to 35,000 Pa;
- and
- wherein the viscous modulus is less than the elastic modulus in the frequency range of from 1 to 100 rad/s.
