1. Goal<br />
Proof the function of PHA in microgravity<br />
2. Objective<br />
Subject of testing is a new full-body cleansing device for astronauts in micro gravity.<br />
It is a well known problem that the three methods of body hygiene - washing, bathing, showering<br />
- are almost not practicable in micro gravity. Right now astronauts use prepacked damp towels<br />
as a substitute for taking a shower.<br />
Since November 1998 we were, in collaboration with JSC, developing the „personal hygiene<br />
assistant“ , short: PHA. This device was tested in a KC135 flight as a new, easy and effective<br />
alternative for full body cleansing.<br />
The device itself - similar to a shower head - is small enough to suit a palm and allows<br />
easy handling, as former tests already proofed. The body of the device holds a sponge in<br />
the middle . The water is injected into the sponge. A cellulose cover on top of the sponge<br />
will be touching the skin during the cleansing process and is able to take off greasy parts<br />
from the skin. This cover will be exchanged more often than the sponge. Like a ring on<br />
the outer edge of the device the suction channels are located. Therefore no water can<br />
escape and the water flow will be controlled. Another advantage is the minimization of<br />
the water consumption. Former tests with the device on the ground show that the principle<br />
functions very well.<br />
KC135 gave us a very important possibility to proof this principle in micro gravity and gain comparable<br />
test data.<br />
