Definitions
- This invention relates to a method for preparing a gas- supersaturated emulsion or suspension and delivering it from a high pressure environment to a gas-depleted site without the immediate onset of cavitation or bubbling.
- the maximum concentration of gas achievable in a liquid is governed by Henry's Law.
- the relatively low solubility at ambient pressure of many gases (for example, oxygen or nitrogen) within a liquid such as water results in a low concentration of the gas in the liquid when these are mixed.
- gases for example, oxygen or nitrogen
- concentration of the gas within the liquid greatly exceeds its solubility at ambient pressure.
- High-pressure compression of a liquid within a liquid emulsion or solid within a liquid suspension can be used to achieve a higher dissolved gas concentration, but disturbance of this gas supersaturated liquid through ejection into a 1 bar environment from the high pressure reservoir will generally result in cavitation inception at or near the exit port.
- Patent No. 4,965,022 recognizes that a similar need may also occur at municipal waste treatment plants and that fish farms require increased dissolved oxygen levels to satisfy the needs of high density aquaculture. Other applications are disclosed in U.S. Patent No. 5,261,875.
- pressurizable confined flow passageways are used to avoid premature liberation of the dissolved oxygen before it is incorporated within the fluid.
- Other oxygen saturation devices are disclosed in U.S. Patent Nos.
- the present invention dispenses with the necessity of compressing fluids within capillary channels, relying instead on use of gas-supersaturated emulsions and suspensions.
- a method is described for the use of emulsions or suspensions to transport a gas-supersaturated liquid from a high pressure reservoir to a relatively low pressure environment (including ambient pressure) , without immediate cavitation inception.
- gas supersaturated emulsions are oxygen, nitrogen, and carbon dioxide.
- the small size of the droplets or particles in conjunction with exposure to a transient high hydrostatic pressure confers stability to the droplets or particles in a manner similar to that provided by small diameter capillary tubes.
- the fine droplets are between about 0.1 micron and about 10 microns in diameter.
- the carrier of the droplets or particles is stable at high gas partial pressures because of the relatively low gas solubility of the carrier as well as the absence of gas nuclei after hydrostatic compression.
- a low gas diffusion coefficient in the carrier results in a slow, delayed release of the gas both from the droplets or particles to the carrier as well as from the emulsion to the gas-depleted environment.
- the high partial pressure of gas in the emulsion creates a high driving pressure gradient between the emulsion and gas-poor surfaces.
- a stream of the gas-supersaturated emulsion can be used to rapidly and efficiently enrich a gas- deprived site such as a liquid by convection of the emulsion to the gas-deprived site. Enrichment of a gas-deprived liquid with gas by diffusion from the gas phase to the liquid is, by contrast, an extremely slow process.
- the lack of bubbles in the effluent additionally permits unimpeded ejection into the gas-depleted site.
- the lack of cavitation inception at or near the exit port allows the effluent to behave as if it were not supersaturated with gas. That is, the ejected stream remains intact rather than disintegrating into a diffuse spray near the exit port due to the rapid growth of gas nuclei.
- the basic steps for forming the gas-supersaturated 5 emulsion are: preparing the emulsion; exposing the emulsion to a gas at a pressure greater than 2 bar; and delivering the emulsion to a gas-depleted environment at ambient pressure.
- the emulsion is exposed to the gas (the primary gas of interest is oxygen) at a pressure of between about 5 bar and about 20 bar.
- the emulsion could be rapidly mixed (at about 1600 rpm, for 5 instance) for several hours during its exposure to the gas at partial pressures between 100 psi and 1500 psi.
- the emulsion could be delivered to a high _ pressure hydrostatic pump in order to further increase the partial pressure of the gas.
- the emulsion is extruded at the output of a pressurizable vessel through a tube, which delivers the 5 emulsion to the outside environment at between about 0.1 and about 10 ml per minute.
- This type of emulsion can be used to efficiently deliver oxygen to the skin, to wounds, or to other environments.
- the high level of oxygen achieved in such tissues by contact of the emulsion with the tissues should be helpful in a variety of ways, such as collagen synthesis, inhibition of anaerobic bacterial growth, and 5 promotion of aerobic metabolism.
- a supersaturated oxygen emulsion can also be used to oxygenate blood for a variety of medical applications. The emulsion is injected directly into the bloodstream, thereby increasing oxygen delivery to the blood.
- a liquid which will be suspended as droplets within a carrier as well as the carrier must be chosen.
- the carrier for the emulsion includes any liquid or semi-solid having a relatively low diffusion rate of the gas to be dissolved. The same techniques apply to the formation of a suspension of particles within a liquid carrier.
- liquids characterized by high viscosity and low gas solubility are the most effective carriers, since these properties tend to increase the liquid's resistance to bubble formation.
- the viscosity of the carrier should be in the 1 centipoise to 10 centipoise range.
- commonly used carriers include glycerin, gels such as hydrogel, vaseline, paraffin, and waxes.
- Gelatins also make effective carriers.
- effective carriers For example,
- droplet materials that _ could be used to provide a stable depot of concentrated oxygen include lipids, liposomes, and oils (the class of oils including mineral, coconut, and vegetable oils) , most of which have a high solubility of oxygen relative to that of 5 water.
- oils the class of oils including mineral, coconut, and vegetable oils
- Solid particles useful in preparing suspensions of the present invention are composed of polymers. These polymers have been found to absorb gases such as oxygen under high 0 pressure conditions and to release the gases without bubble formation upon exposure to ambient pressure.
- the preferred polymers include polyacrylamide (in either its unhydrated or hydrated form) , polypropylene, polycarbonate, polyethylene, 5 polylactic acid, polyglycolic acid, polycaprolactone, polyethylene glycol, polystyrene, polysorbate, polymethyl methacrylate and co-polymers thereof.
- the size of the solid particles are within the range of 0.1 to 10 micron.
- Any particle or droplet could also be micro or nano- encapsulated with a semi-permeable surface coating that further controls the rate of diffusion from the particle or droplet to the carrier. Encapsulation can be achieved through well-known techniques such as coacervation or vapor deposition.
- emulsion In order to form an emulsion, one can obtain a commercially available emulsion comprising a desired liquid suspended in water. After centrifuging this emulsion and decanting the supernatant, the desired droplets can be resuspended in a carrier of choice. Likewise, in forming a suspension, one can centrifuge a suspension of particles, decant the supernatant, and resuspend the particles in another carrier of choice.
- Glycerin was chosen as a carrier because of its low oxygen solubility (0.008 cc 0 2 /g/atm.), relatively high viscosity, and low rate of oxygen diffusion. Moreover, it is a biocompatible liquid, thereby allowing application to the skin or to wounds.
- Perfluorochemical (PFC) particles were chosen to be suspended in the carrier due to their high oxygen solubility (0.5 cc 0 2 /g/atm.), their inherent ability to form into small particles (typically equal to or less than 0.5 ⁇ m) , and their biocompatibility.
- the PFC/glycerin suspension (200 ml) was placed in a 300 ml capacity Parr reactor vessel, and the suspension was exposed to oxygen at partial pressures as high as 500 to 1500 psi during rapid mixing (at about 1600 rpm) with an impeller stirrer. High oxygen partial pressures were required to drive the oxygen into the suspension over a period of many hours because of the slow rate of diffusion of oxygen through the glycerin.
- the oxygen partial pressure developed in the suspension after the above treatment and overnight exposure to oxygen at 300 psi (without stirring) was estimated to be approximately 10 atm.
- the suspension contained approximately 5 i ml 0 2 /g. Since the suspension ordinarily contains about 0.1 ml 0 2 /g/bar in water, and the percent volume of PFC in glycerin is similar to that in water, the partial pressure of the gas must have been about 10 bars. 0
- a simple dispenser for the oxygen-rich cream emulsion can consist of a syringe type design, with the barrel driven by manual rotation of a piston that advances as a screw on threads, similar to the operation of commercially available
- indeflators used to pressurize high pressure balloons (as high as 300 psi) on angioplasty catheters.
- a valve at the distal end of the syringe would allow the cream to be squeezed from the syringe in a controlled manner. After dispensing a desired amount of cream, the stopcock would be closed and additional pressure applied to maintain a hydrostatic pressure that equals or exceeds the dissolved gas partial pressure.
- the syringe would be fabricated from materials that are impermeable to oxygen.
