Seal groove is sealing device, at cover body lower edge, in soft channel-shaped, for the downward part of dividing a word with a hyphen at the end of a line of cover body, concordant or both sides are wider, to adapt to there be good coincideing to the recessed flat patient facial region's skin in buccal, can also prevent from applying weighing wounded patient facial region's skin for a long time.
Sealing device also can change air bag, non-woven fabric elastomer etc. Oxygen release pipe is oxygen diffuse releasing device, in seal groove or at cover body lower edge or in the two junction, rounds to half cycle, for the pipeline with aperture or sulculus, also can be channel-shaped, or be only a pipeline tapping, its end is in one end of seal groove or side, and outside is Oxygen tube joint.
Oxygen channel directly can be connected on the spot with multiple oxygen supply equipment, the little joint of near-end is connected with the oxygen tube junction of oxygen release pipe end, the coupling of far-end twin adapter can connect with the air outlet adapter of anesthesia respirator etc.
Oxygen channel distal joint also can be ordinary couplings. Mask fixing band attachment is in below cover body lateral margin, can be fixed leg, fixing hole, fixing buckle, fixing adhesive tape, in other position or can configure in addition.
Mask fixing band is elastomeric material, non-elastic material, non-woven elastomer, fixing after neck, after ear. Little for oxygen uptake pipeline near-end joint 9 is connected with the Oxygen tube joint 5 of face shield, and far-end twin adapter is connected with source of oxygen, opens source of oxygen, after adjusting oxygen flow, face shield as wearing common oxygen absorption mask at the mouth and nose place of patient, gets final product oxygen uptake.
Due to be below face shield, side oxygen supply, oxygen is covered with below face masks, and fraction of inspired oxygen is higher, comparatively fast can promote blood oxygen saturation, increase oxygen utilization rate, reduce or prevent CO2 from accumulating; Diffusivity oxygen uptake, avoids the impact of oxygen stream to patient's snout and mucosa, alleviates the sense of discomfort of patient's oxygen uptake. In order to alleviate face shield to patient pressure and sense of discomfort, oxygen connection larger above existing face shield being cancelled, changes the oxygen release pipe of side-lower into; Change soft contact surface into patient facial region contact position below face shield.
For anti-cross infection, protection doctors and patients Fang Shuan, selects airtight oxygen uptake. Realize resistance bacterium airing function with airflow filtering device, side filter element etc. For intuitively showing patient's autonomous respiration situation, being provided with breathing finder, facilitating family numbers of patients to observe, reduce medical personnel's workload. The foregoing is only preferred embodiment of the present invention, is not restriction the present invention, the increase and decrease, title replacing etc.

Pulmonary Tuberculosis. AARC Honors. Pioneers in Oxygen Therapy. Antoine-Laurent Lavoisier. Antoine Lavoisier , a French chemist, is considered the father of modern chemistry. He developed a new system of chemical nomenclature and is responsible for naming oxygen acid-former and a number of other elements. Carl Wilhelm Scheele. Carl Wilhelm Scheele , a German-Swedish chemist, was the first to isolate "fire-air" oxygen.
Although his discovery was documented in letters to Antoine Lavoisier in , his research was not submitted for publication until Joseph Priestley. Joseph Priestley was an English scientist and theologian who authored more than publications. His text, The History and Present State of Electricity, published in was considered a standard for over a century. Priestley published six volumes of Experiments and Observations on Different Kinds of Air in which he documented the discovery of several gases including what later would be known as nitrogen, ammonia, nitrous oxide, nitric oxide, and carbon monoxide.
Priestley is credited with the discovery of soda water. His experiments with heated mercuric oxide resulted in his discovery of "deplogisticated air", later known as oxygen. It was discovered much later that Scheele's research was documented several months prior to Priestley's, thus the confusion over to whom the credit should be given for the discovery of oxygen.
In , a medal honoring Joseph Priestley was minted to commemorate the bicentennial of the discovery of oxygen. This front side of the medal from the collection of Felix Khusid is shown. This back side of the medal from the collection of Felix Khusid is shown.
Thomas Beddoes. He used oxygen and nitrous oxide to treat asthma, pulmonary tuberculosis, congestive heart failure and other maladies. John Haldane. John Scott Haldane was a Scottish physiologist and physician who researched respiratory physiology. He wrote the first paper on the rational use of oxygen and was the first to describe the effects of oxygen on the pulmonary system.
Haldane was the first to describe the effect of carbon dioxide on respiratory drive. His research on carbon monoxide in coal mines led to safer working conditions for miners. Haldane was involved in early research on hyperbaric oxygen exposure. He is credited with developing a method for measuring oxygen content and designing the modern oxygen mask. Alvan Barach. Alvan Barach was an American physician who laid the foundation for long term oxygen therapy in chronic pulmonary disease.
He was involved with modification of early oxygen tents to include ice for cooling and soda-lime for carbon dioxide absorption. Barach developed the meter mask that allowed for adjustable oxygen concentrations.
He developed a hood for delivery of continuous positive airway pressure. He also designed the first portable oxygen system for his patients with emphysema. Click here to listen to an audio interview of Dr. Barach by Dr. Barach, MD.
The audio cassette package of Dr. Tom Petty's interview with Dr. Alvan Barach is shown. The cassette is from the collection of Felix Khusid. Glenn Millikan. Glenn Allan Millikan , an American physiologist, developed an ear probe that used two wave-lengths of light in an ear oxygen meter.
The device was used to detect hypoxia in pilots during World War II. F rom there, it took a little under years for scientists and doctors to understand how to use oxygen to help those with varying illnesses and diseases.
In , the first ever recorded use of oxygen was documented for a medical purpose. This medical procedure was to treat a patient with pneumonia. This revolutionary treatment was administered and pioneered by Dr. George Holtzapple. Just two years later, a product was invented and sold that stored enough oxygen for intermittent use.
A t the turn of the twentieth century, a nasal catheter was used as the connection between the oxygen and the patient. M edical use of oxygen made major leaps and bounds up until World War II. Oxygen was mainly being used in hospitals to treat patients with a variety of respiratory issues.
This portable oxygen was used strictly in ambulances and on the scene of medical emergencies. Finally, you could own your own oxygen therapy unit in your home! Although they were readily available by a supplier that delivered tanks, these tanks were much larger than those today.
