Philips Respironics has released HomeLox, the only system available for 
patients to generate and store liquid oxygen at home. Not relying on deliveries from outside vendors will help simplify the lives of patients dependent on oxygen, and home caretakers will be able to streamline their operations using the new machines.
From the press release:
HomeLox generates liquid oxygen by converting room air into oxygen, and then chilling and converting it to liquid form using a proprietary refrigerant along with standard refrigeration technology found in industrial and household applications. The liquid oxygen is stored within the HomeLox unit until transferred to GoLox for portable use.
In addition to giving users the ability to generate and store liquid oxygen at home, the HomeLox system features a new hands-free clean filling process. To fill the GoLox portable device, the user simply places the unit on top of HomeLox, turns and locks the unit, and pulls the filling lever. The hands-free process helps reduce freezing, overfilling, and under filling.
For homecare providers, the new HomeLox liquid system reduces the cost and complexity of current systems commonly associated with delivered liquid oxygen systems which may include the purchase of specialized vehicles, testing equipment, and storage containers, as well as recurrent deliveries and filling-related service calls.
