Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and / or treatment type.

The application of matrix metalloproteinase (MMP) inhibitors to the skin inhibits the degradation of proteins found in the skin including collagen, elastin, and other basement membrane and extracellular matrix protein. MMP inhibitors may be used in both cosmetic compositions and pharmaceutical compositions for application to skin. MMP inhibitors are formulated with a cosmetically suitable vehicle or pharmaceutically acceptable excipient for application to the skin as creams, lotions, ointments, solutions, face masks, etc. As cosmetics, the inventive MMP inhibitor compositions are applied to the skin to prevent or reduce the appearance of wrinkles, pigmentation changes, loss of elasticity, or other effects associated with aging or sun damage. As pharmaceuticals, the inventive MMP inhibitor compositions may also be applied to the skin to treat or prevent a skin disease (e.g., proliferative disease, inflammatory disease).

Disclosed is an apparatus and method for the delivery of inspired gas, e.g., supplemental O2, to a person combined with gas sampling, including for the purpose of monitoring of the ventilation of the person. In the invention, the delivery of inspired gas and gas sampling are accomplished without the use of a sealed face mask. The apparatus of one embodiment of the present invention comprises an oxygen delivery device, nasal airway pressure sampling devices, optionally an oral airway pressure sampling device and at least one pressure analyzer connected to the sampling devices which determine the phase of the person's respiration cycle and the person's primary airway. The oxygen delivery device is connected to a controller such that it delivers a higher flow of oxygen to the person during the inhalation phase of the person's respiratory cycle. The invention thus increases end tidal oxygen concentrations. The invention further comprises carbon dioxide sampling tubes that continuously sample gas from two nasal sites and the mouth. The nasal sampling tubes are connected to a switching valve that is in turn connected to a capnometer which determines carbon dioxide concentration during exhalation. The oral gas sampling site is connected to a second capnometer.

An emergency medical kit for use, particularly by a non-professional, to render emergency medical treatment to a patient, includes: a pressurized-oxygen container within a housing; a face mask within the housing for application to the face of a patient requiring cardiopulmonary resuscitation; and a respiratory pump within the housing connected to the pressurized-oxygen container so as to be driven thereby to supply oxygen to the mask for inhalation by the patient, and to discharge the exhalations of the patient via the face mask to the atmosphere. The face mask includes an inflatable seal around its circumference engageable with the face of the patient receiving the mask for sealing the interior of the mask; a pressure sensor sensing the pressure in the inflatable seal; and an indicator for indicating whether the face mask is properly applied to the face of the patient. The kit further includes a neck rest having straps for attaching the face mask thereto in contact with the patient's face when the patient's head is placed on the head rest. According to a most essential aspect of the invention there is provided an emergency, fully automatic kit, based on non-invasive means for performing all stages of the “chain of survival” (including: external defibrillation, ventilation and automatic chest compression) by a single operator.

The nonwoven fibrous layer is molded in a cup-shaped configuration and has a surface fuzz value of not less than 7.5 after being subjected to a surface fuzz abrasion test.

A face mask for ventilation of a patient. A face piece is disposed on the patient's face. An oral tube and a nasal tube are disposed through corresponding ports in the face piece. The oral tube extends through the mouth of the patient and the nasal tube extends through the nasal passage of the patient. The ends of the oral tube and the nasal tube are received in the posterior oropharynx of the patient. An adapter is connected to the ends of the oral tube and the nasal tube exteriorly of the face piece. Oxygen is introduced into an inlet port of the adapter wherein the oxygen enters the oral tube and the nasal tube concomitantly and ventilates the patient.

Disclosed is an apparatus and method for the delivery of supplemental oxygen gas to a person combined with the monitoring of the ventilation of the person with both being accomplished without the use of a sealed face mask. Preferred embodiments of the present invention combine an oxygen delivery device, a nasal airway pressure sampling device, an oral airway pressure sampling device, and a pressure analyzer connected to the sampling devices to determine the phase of the person's respiration cycle and the person's primary airway. The oxygen delivery device is connected to a controller such that it delivers a higher flow of oxygen to the person during the inhalation phase of the person's respiratory cycle. The invention thus increases end tidal oxygen concentrations with improved efficiency comparative to known open airway devices. Embodiments of the invention can include carbon dioxide sampling tubes that continuously sample air from the nose and mouth to determine carbon dioxide concentration during exhalation.

The present invention relates to aliphatic polyester microfibers, films having a microfibrillated surface, and methods of making the same. Microfibers of the invention can be prepared by imparting fluid energy, typically in the form of high-pressure water jets, to a highly oriented, highly crystalline, aliphatic polyester film to liberate microfibers therefrom. Microfibrillated films of the invention find use as tape backings, filters for particulate contaminants, such as face masks and water or air filters, fibrous mats, such as those used for removal of oil from water and those used as wipes, and thermal and acoustical insulation. Microfibers of the invention, when removed from the film matrix may be used in the preparation of woven or nonwoven articles and used as wipes for the removal of debris or dust from a surface. The microfibers and microfibrillated articles of the invention may be biodegradable, rendering them useful for geotextiles.

A therapeutic face mask comprises a face-engaging portion and a single connector having a mask-engaging end and a single treatment-receiving end which has a single attachment mounting for detachably sealingly receiving a treatment attachment, such as an oxygen reservoir bag or a nebulizer.
