- 1. A method of providing a medical gas to a patient in need thereof comprising providing said medical gas in a plurality of compressed gas cartridges containing an amount of said medical gas substantially corresponding to a unit dose of said medical gas for said patient, and providing said patient with means for accessing said medical gas from said plurality of compressed gas cartridges upon said need.
- 10. A method of providing a medical gas to a patient in need thereof comprising providing said medical gas from a compressed gas cartridge, releasing said pressurized medical gas into a chamber so as to reduce said pressure of said medical gas, and transferring said medical gas at said reduced pressure to said patient upon said need.
- 24. A method of providing a medical gas to a patient in need thereof comprising selecting a predetermined medical gas required by said patient, providing said predetermined medical gas in at least one compressed gas cartridge, and providing said patient with a means for accessing said medical gas from said at least one compressed gas cartridge only if said at least one compressed gas cartridge includes said predetermined medical gas.
- 27. Apparatus for the administration of a medical gas to a patient comprising a housing, a cassette associated with said housing containing a compressed gas cartridge containing at least an amount of said medical gas substantially as required for a single dose for said patient, and patient supply means for providing said medical gas to said patient.
- 48. Apparatus for the administration of a medical gas to a patient comprising a portable housing, a plurality of compressed gas cartridges associated with said portable housing containing a predetermined amount of said medical gas sufficient for normal respiration by said patient, and patient supply means for providing said predetermined amount of said medical gas to said patient.
- 59. Apparatus for the administration of a medical gas to a patient comprising a housing, a compressed gas cartridge disposed within said housing and containing a predetermined amount of said medical gas sufficient for normal respiration by said patient, and patient supply means for providing said medical gas to said patient, said housing including an upper portion and a lower portion connectable with said upper portion in a configuration in which said housing is closed, said compressed gas cartridge having a size and configuration whereby said housing may be closed with said compressed gas cartridge disposed within said housing and said compressed gas cartridge can supply said medical gas to said patient from said housing only when said housing is closed.
- 76. Apparatus for the administration of a medical gas to a patient comprising a sealable housing, a cassette including a compressed gas cartridge sealed in said cassette and mountable within said housing when said housing is sealed, said compressed gas cartridge containing a predetermined amount of said medical gas, patient supply means for providing said medical gas to said patient, and gas delivery means for sealably delivering said medical gas from said compressed gas cartridge to said patient only when said housing is sealed.
- 93. Apparatus for the administration of a medical gas to a patient comprising a housing, a removable compressed gas cartridge within said housing containing a predetermined amount of said medical gas, patient supply means for providing said predetermined amount of said medical gas to said patient, connection means for connecting said compressed gas cartridge with said patient supply means when said compressed gas cartridge is disposed within said housing for supplying said predetermined amount of said medical gas to said patient supply means, a pressure sensor for sensing the pressure of said medical gas released from said compressed gas cartridge, and control means for preventing delivery of said medical gas to said patient supply means based on the pressure sensed by said pressure sensor.
- 99. Apparatus for the administration of a medical gas to a patient comprising a housing, a removable compressed gas cartridge within said housing containing a predetermined amount of said medical gas, and a patient interface for providing said predetermined amount of said medical gas to said patient, said apparatus having an overall weight of less than about 48 ounces.
- 106. Apparatus for the administration of a medical gas to a patient comprising a housing, a removable cassette removably mounted within said housing, said removable cassette including at least one compressed gas cartridge containing a predetermined amount of said medical gas, patient supply means for providing said predetermined amount of said medical gas to said patient, mounting means for mounting said removable cassette within said housing, said mounting means comprising first acceptance means and said removable cassette including second acceptance means whereby said mounting means will only accept said removable cassette having second acceptance means which are compatible with said first acceptance means.
- 115. Apparatus for the administration of a medical gas to a patient comprises a housing including an upper portion and a lower portion, a removable cassette holding at least one compressed gas cartridge within said housing, said at least one compressed gas cartridge including a predetermined amount of said medical gas, patient supply means for providing said predetermined amount of said medical gas to said patient, connection means for sealingly connecting said upper portion of said housing to said lower portion of said housing with said cassette within said housing, said connecting means including first upper connecting means disposed at said lower end of said upper portion of said housing, second upper connecting means disposed above said first upper connecting means on said upper portion of said housing, first lower connecting means disposed at the upper end of said lower portion of said housing, second lower connecting means disposed below said first lower connecting means on said lower portion of said housing, said first upper connecting means adapted to cooperatively engage said second lower connecting means to provide an intermediate closed configuration for said housing, and said second upper connecting means adapted to cooperatively engage said first lower connecting means to provide a sealed configuration for said housing, the distances between said first and second upper connecting means and said first and second lower connecting means being adapted so that said first upper connecting means engages said second lower connecting means before said second upper connecting means engages said first lower connecting means.
- 127. Apparatus for the administration of a medical gas to a patient comprising a housing, a removable cassette within said housing, said removable cassette including a plurality of compressed gas cartridges sealed therein, each of said plurality of compressed gas cartridges including a predetermined amount of a portion of said medical gas, patient supply means for providing said medical gas to said patient, said housing including an upper portion and a lower portion connectable to said upper portion in a configuration in which said housing is closed, said removable cassette being mounted in said lower portion of said housing, and a plurality of gas connection members corresponding to said plurality of compressed gas cartridges and mounted in said upper portion of said housing whereby when said upper portion of said housing is connected to said lower portion of said housing said plurality of gas connection members connect said upper portion of said housing with said corresponding plurality of compressed gas cartridges.
- 133. Apparatus for the administration of a medical gas to a patient comprising a housing, a cassette mountable within said housing, said cassette including at least one compressed gas cartridge sealed therein containing a predetermined amount of said medical gas, patient supply means for supplying said predetermined amount of said medical gas to said patient, and gas delivery means for delivering said medical gas from said cassette to said patient supply means.
