Patented June 7 6, 1933 UNITED STATES PATENT OFFICE I'HAJDDEUB A. TAYLOR, OI L'UZI'KIN, TEXAS- I APPARATUS FOR BEGULA'IING THE TEMPERATURE AND OXYGEN CONTENTS 01' AIR Application filed fiecember 19, 1930. Serial No. 503,380.
, My invention relates to an improved apparatus for administering oxygen to patlents and for regulating the temperature of the air.
The invention is an improvement upon that shown in my prior apglication for patent,-
Serial N o. 4.7 9,150 filed ept. 2, 1930.
It is an object of the present inventlon to provide a device for administering oxygen to a patientin which device the air may be mixed with oxygen in the desired proportions without difliciilty.
I also desire to be able to eliminate carbon dioxide from the air passing to the patient.
I aim also to provide for the cooling of the air passing to the patient so that the device may be used in treating fever or to render the air of the desired temperature.
It is an object to provide a device which may be used to automatically control the air delivered to a patient and to feed into the air stream medicated ingredients desired in the treatment of the patient. a
I also desire to improve the means forcontrolling the temperature of the air so that it Th will operate most effectively.
In the drawings herewith, Fig. l is a perspective view showing the apparatus assembled for use.
. Fig. 2 is a side elevation of a slightly modified form of tent employed with the device.
Fig. 3 is a front elevation of the cooling box.
Fig. 4 is a-top plan view of the same.
Fig. 5 is a transverse section on the plane 5-5 of Fig. 3.
, Fig. 6 is a vertical section through the box with a modified container for the cooling agent.

into which the oxy enated and cooled air may be delivered. T is tent may have awindow 3 so that the patient may be observed. If desired a larger tent, shown at-4 in Fig. 2, may be used to enclose the greaterportion of the bed so that the tem tients body may also e regulated. Any number of windows 5 may be employed, as desired. The tents may berized fabric or other similar material.
To deliver treated air to the patient, a treating box 6 is arranged at one side of the tent and forming a closure for an opening in sald tent. Said box may receive oxygen delivered thereto by way of a flexible pipe 7 connected with an oxygen tank 8. Said pipe may have indicators 9 thereon toshow ing 10 at the upper end and a similar opening 11 at the lower end, said openings being presented through the side of the tent. e upper opening has a door or valve 12 hinged inside the opening and adapted to close the opening or, by adjustment, through a knob 13, to control the amount of air pass ing from the tent to the box.
The upper end of the box has a door, 15 hinged at 16, which may be opened to insert into the box the ice container 17. Said door has a smaller auxiliary door 18 which may be opened to allow a limited amount of air to enter the box or to accommodate the aim tainer shown in Fig. 7. Around the edge of theopening closed by the door 15, and on the inner side of the box, are inwardly turned flanges 19, to support a foraminated plate, or screen 20 upon which medicated cotton or similar material may be placed, to deliver any desired vapor or fumes of medicine to the air stream.
The ice container 17 is supported oif the bottom 21 of the box upon brackets 22 on the erature of the patom of the box where it is received into a drip pan 24;.
The drip pan is shallow and its upper margin ad]acent the opening 11 is recurved to form a support at 27 for a foraminated container 28, for soda lime or similar compound. Said container 28 is placed immediately in front of the opening 11, so that the air passing to said opening will pass through the container and into contact with the soda lime, and thus the carbon dioxide in the air may be absorbed in the container. A valve or door 29 is placed in position to regulate the amount of air, or other gaseous fluid passing into the tent.
The oxygen enters the box by way of inlet pipes 30 or 31 in the side of the box near the bottom. If it is desired to cool the oxygen,
it may enter pipe 31 which may be coiled or bent into folds in the bottom of the drip pan and be thus cooled by the drippings from the ice. These drippings may drain from the box through the openings 32 and pipe 33. lVhere the oxygen passes through the'pipe 31 it is delivered directly into the tent through the outlet end 34 projecting from the opening 11.
Where solid carbon dioxide-is to be used as a cooling agent, a separate container 35 may be used, said container being formed to seat in the upper end of the ice container 17 An upward extension 36 on the container 35 may extend through the opening or door 18 and be closed by a cover plug 37 having a vent tube 38 thereon which may convey the carbon dioxide gas to some desired point where it will not contaminate the air delivered to the patient. This container 35 may be inserted into position through a door 11 in the end of the box so that the same may door 15 and a draft of air will be drawn in over the ice and delivered through the box as the colder air will then circulate downwardly due to its greater weight. Oxygen in the desired amount may be mixed with the air,. thus passing to the tent, it being possible, however, to cut off the oxygen supply where it is notneeded. Where the larger tent is used the largerdoor 15 may be opened and suflicient fresh air may enter to entirely replace the supply in the tent in a short time. Oxygen may simultaneously be supplied and the necessity for the use of the soda lime to eliminate the CO may be avoided except. in extreme cases where an excessive amount of CO is thrown off by the patient. A simple and convenient structure is thus obtained which can be operated at low cost. I am enabled to use my invention to regulate the temperature alone in cases of fever, or in hot weather where it is desirable to maintain an agreeable temperature for sleeping. I am also able to keep the air pure and to supply such oxygen or other ingredient in the air as may be desired in the treatment of the particular patient being considered. The device may be used to maintain comfortable sleeping conditions where sickness is not present, and it is adapted for use generally where the air is to be refrigerated for any purpose.
Having thus described my invention, what I claim as new and desire to protect by Letters Patent is: v
1. A device of the character described including an enclosure having an upper opening at one side thereof, a portable treating box adapted to be connected in said opening to close the same, an upper inlet and a lower outlet from said box connecting with said enclosure, a container in said box having foraminated walls spaced from the walls of said box to contain ice, means to deliver oxygen to said device and dampers 1n said inlet be renewed or removed without disturbing and said outlet openings-to regulate the conthe patient.
Any preferred form of refrigerating device may be employed including ice, solid CO electrical refrigerator or the like.
The installation thus assembled enables me to easily control both the temperature of the air delivered to the patient as well as the oxygen content thereof and this is done without the necessity of pumps, fans or compressors. The relatively warm air from the tent will circulate into the box through the opening 10 and, in passing over the ice or the cooled sides of the container by convection the moisture in the air may be condensed and eliminated. Any carbon dioxide contained with the air will be absorbed in the soda lime container and the patient will thus be assured of a supply of fresh air at all times.
Where an additional supply of fresh air is desired, I may open either the door 18 or the vectional circulation of air to and from said box and said enclosure.
2. A device of the character described including an enclosure having an upper opening at one side thereof, a portable treating box adapted to be connected in said opening to close the same, an upper inlet and a lower outlet from said box connecting with said enclosure, a container in said box having foraminated walls spaced from the walls of said.
box to contain ice, an upper air inlet to said box outside said enclosure, means to control said air inlet, means to deliver oxygen to said device and dampers in said inlet and said outlet openings from said enclosure to regulate the convection'al circulation of air to andfrom said box and said enclosure.
3. A portable air treatingbox adapted to be connected within an opening in a tent, said box being constructed to circulate air to and from saidtent, inlet and outlet openings therein to said tent, an inwardly opemn damperin said inlet, an ice container 1n sai box, a pan in said box, means to conduct liquid from said container to said pan, means to deliver oxygen through said box to said tent, means to cool said oxygen, and a damper in said outlet, inthe manner described.
4. A portable air treating box adapted to be connected within an openin in a tent, said box being constructed to circu ate air to and from said tent, inlet and outlet openings therein to said tent, an inwardly opening damper in said box, an ice container msaid THADDEUS A. TAYLOR.
