CA2241930A1 - Process and device for non-intrusive injection of fluids and for bodily cleaning - Google Patents

Abstract

The invention describes a process and devices by means of which the transport of fluid substances in or through the human skin can be improved over a defined period without any irreversible skin changes. According to the invention, heat and cold are alternately applied to closely adjacent and very small areas of the skin surfaces for equal periods in such a way that hot and cold regions border one another and are reversed in a predetermined time sequence. In addition to the alternating application of heat and cold, electric current and/or overpressure and/or underpressure may a lso be applied to the skin surface at defined time intervals. The devices described are intended for the non-invasive drawing off of body fluid and/or the injection of fluids and describe the application of thermo-contrast showers and cleaning devices.

Device according to claim 62 characterized thereby that along the lateral surfaces of each module (G15) there are drainage holes which lie below the upper limits of the modules (G15) and are connected by means of cross ducts with holes toward the inside, whereby the height of the drainage ducts (G4) is arranged so that they form a common drainage network through the removal of the fluid toward the outside can take place.

64.
Device according to claim 45 characterized thereby that the wash water has a temperature in the range from -30°C to +60°C, whereby warm materials or means have a temperature between +33=0.1°C and +60°C and cold material or means have a temperature between -30°C and +33=0.1°C.

65.
Device according to claim 45 characterized thereby that the cleaning of the human body is carried out with a hand shower which consists of a hand grip and at least one shower head or in a shower stall with at least one automatically controlled shower head.

66.
Device according to claim 45 or 59 characterized thereby that the modules are formed as folding bellows so that several folding bellow constructions are fitted into each other and thus form supply and drainage ducts.

67.
Process for cleaning the human body by means of wash water whereby the wash water is removed from the skin surface through drainage ducts under negative pressure characterized thereby that contiguous areas of the skin surface are simultaneously subjected to hot and cold wash water through separate ducts under the production of overpressure on the skin surface.
