Mechanical device with simulated skin substrate
An apparatus for evaluating a material is provided. In one aspect, the apparatus is an adjustable artificial arm for transmitting fluid into the material. An artificial skin, for example, is removably attached to the artificial arm, and the material is placed over the artificial skin. The fluid is insulted into the material proximate the artificial skin. The artificial skin is evaluated for wetness or dryness to prescreen the material. In another aspect, an artificial torso is provided through which fluid is transmitted and insulted into the material for evaluation.
1. An apparatus for evaluating a material insulted with a fluid, the apparatus comprising:
an adjustable object with an arcuate surface defining a circumference, the arcuate surface configured for adjustment of the circumference to accommodate a material disposed on the arcuate surface, the material ranging in size from a diaper to an adult undergarment;
a substrate attached to the arcuate surface of the adjustable object; and
means for injecting simulated human fluid into the material contactable with the substrate, the adjustable object configured to position the substrate for evaluation.
2. The apparatus as in claim 1 , wherein the material is an absorbent article selected from the group consisting of disposable or non-disposable feminine products, nursing healthcare products, disposable or non-disposable child training pants, face masks, bandages, gloves and combinations thereof.
3. The apparatus as in claim 1 , wherein the simulated human fluid is selected from the group consisting of water, saline, synthetic menses, synthetic urine, artificial breast milk, blood, 0.9% sodium chloride solution, colored solution, exudate and combinations thereof.
4. The apparatus as in claim 1 , wherein the object is selected from the group consisting of a lower-torso mannequin, an upper-torso mannequin, a full-body mannequin, a mannequin forearm, a mannequin hand, a mannequin foot, a mannequin leg, a mannequin head, and combinations thereof.
5. The apparatus as in claim 1 , wherein the object is formed of a silicone, a neoprene, a plastic, an acetyl plastic, an acrylic plastic, an elastomeric material, a high density polyethylene, a polymer, a metal, a glass, a composite material and combinations thereof.
6. The apparatus as in claim 1 , further comprising a fluid delivery device and a tubing in communication with the adjustable object, the tubing having an opening terminating at a fluid injection port defined in the adjustable object, the fluid delivery device and the tubing cooperably configured to insult a predetermined amount of the simulated human fluid through the fluid injection port.
7. The apparatus as in claim 1 , further comprising a fluid delivery device, wherein the fluid delivery device is a digital pump in communication with an embedded tubing within the adjustable object, the embedded tubing having an opening terminating at a fluid injection port of the adjustable object, the digital pump and the embedded tubing cooperably configured to insult a predetermined amount of the simulated human fluid through the fluid injection port.
8. The apparatus as in claim 1 , further comprising a measuring device configured to measure a condition of the substrate.
9. The apparatus as in claim 1 , wherein the adjustable object is adjusted by one of swiveling, rotating, retracting, extending, ratcheting, inclining, reclining, and combinations thereof.
10. The apparatus as in claim 1 , wherein a circumference of the adjustable object is adjustable by one of electrical, hydraulic, pneumatic, and manual adjustment.
11. The apparatus as in claim 8 , wherein the measuring device is configured to record the condition of the substrate.
12. The apparatus as in claim 8 , wherein the measuring device measures the condition of the substrate by one of capacitance, conductance, electrical impedance, gravimetric and TEWL evaluations.
13. The apparatus as in claim 8 , further comprising a monitor in electrical communication with the measuring device, the monitor configured to display the condition of the substrate.
