Abstract

The present invention provides an apparatus for producing medical foam for wound care or hair stimulation. The apparatus includes a foam generation unit having a fluid reservoir, a fluid delivery line and a foam generation tip. The apparatus also includes a compressed gas unit having at least one container of compressed gas, a source of electric power, and a gas regulator valve. A supply of wound care or hair stimulating solution is communicably connected to the foam generation tip such that when the apparatus is operated medical foam is produced by the foam generator tip.

First claim

What is claimed is:

1. An apparatus for producing medical foam, the apparatus comprising:
a portable, compressed CO 2 unit, said CO 2 unit including a cylinder cartridge puncture valve and a fitting adapted for selective attachment of a compressed gas cylinder thereto, the compressed CO 2 unit being connected to a gas delivery line;
a foam generation tip including two inlets and an outlet, the two inlets include an air hose inlet and a foam solution delivery line, said air hose inlet directly connected to the gas delivery line for the passage of the compressed CO 2 from the CO 2 unit to the foam generation tip;
a reservoir containing treatment solution the reservoir directly connected to the foam generation tip via the foam solution delivery line for the passage of the solution from the reservoir to the foam generation tip; and
whereby initiating the CO 2 unit causes compressed CO 2 to be delivered through the gas delivery line to the air hose inlet of the foam generation tip, which CO 2 draws the solution from the reservoir into the foam solution delivery line of the foam generation tip such that the foam generation tip generates a CO 2 enriched medical foam.

2. A method of treatment, said method comprising:
providing a portable compressed CO 2 unit, the CO 2 unit including a cylinder cartridge puncture valve and a fitting adapted for selective attachment of a compressed gas cylinder thereto, the compressed CO 2 unit being connected to a gas delivery line;
selectively securing a compressed gas cylinder containing compressed CO 2 to the compressed CO 2 unit;
attaching a foam generation tip to the gas delivery line, the foam generation tip including two inlets and an outlet, the two inlets including an air hose inlet and a foam solution delivery line, the air hose inlet being directly connected to the gas delivery line for the passage of compressed CO 2 from the CO 2 unit to the foam generation tip;
providing a reservoir with a therapy solution;
communicably interconnecting the reservoir with the foam solution delivery line of the foam generation tip for the passage of solution from the reservoir to the foam generation tip;
initiating the CO 2 unit to deliver compressed CO 2 from the compressed gas cylinder though said gas delivery line and to the gas delivery line of said foam generation tip, which CO 2 draws said solution from the reservoir through the foam solution delivery line and into the foam generation tip such that the foam generation tip generates a CO 2 enriched medical foam which is output through the outlet of the foam generation tip; and
applying the C0 2 enriched medical foam.
