Patented Jan. 2, 1945 OFFICE BASS INET ORGANIZATION Joseph Kreiselman, Washington, D. C. 1 Application January 22, 1942, Serial No. {127,733

My invention relates to a bassinet organization adapted for the care of infants, particularly new born babies, andhas for its object to provide in an easily accessible and convenient form anadjustable means of supporting the infant in desired positions, meansf'or properly tempermg the bed on which the infant lies and the atmosphere surrounding the infant and for giving to it a suitable moisture content, means for withdrawing saliva or other accumulations from the mouth and other passages of the infant, means for giving to the infant an atmosphere suitably enriched with oxygen, andresuscitation means including oxygen supplying means for bringing about and establishing correct breathing by a new born infant threatened wtih asphyxiation from breathing failure.

A percentage of infants are born which, either have a very precarious hold upon life and require special treatment of the most prompt and effective kind in order to be kept alive. Somebecause of premature birth or for other causes, I

times the breathing doestnot establish itself and asphyxiation .impends. Under such conditions not only must resuscitation means be promptly applied to establish breathing but it must be under conditions where the least shock can result and under conditions where the proper temperature and humidity of surrounding atmosphere free from drafts will be present and at all. times available. And in other cases, where breathing has been establishednormally but from other causes the life of an infant isthreatened,

. ganization embodying my improvements thereto.

similar conditions of freedomifrom shock, suitable support for the infant in an atmosphereof proper temperature and humidity and suitably oxygen-enriched, are called for. i

It. is: a principal object or my invention, there fore, to provide abassinetl organization includ ing the means broadly stated above, whereby an infant born in an abnormal condition from any cause so that. extinction or life is. threatened, can be immediately positioned where. shock is avoid-V ed, and any and all. of the instmmentalities for bringing it to normal condition are.v conveniently andimmediately available.

In carrying out my invention herein described and claimed I have employed among. other things the resuscitation. apparatus of patents to Robert B; SWOpe; and myself, Numbers: 1,848,232, 1,848,233 and 1,848,234,. allgran-ted on. March.- 8, 19-32; for

resuscitation apparatus; and. special inhaler used therewith, in combination. with a. bassinet chamher with means for adi-usting; the positioning of the infant therein and variousrinstnwnentalie ioia m, (01. 128-1) 1 ties for supplying oxygen, properly heating and humidifying the atmosphere within the bassinet chamber and supplying oxygen to the f infant where that is called for.

Thefull objects and advantages of myinvention will appear in connection with the description given in the following specification and the novel features by which are obtained the valuable and advantageous results above referred to will be particularly pointed out in the claim.

suitable porous material, which is enclosed within a. covermember 21, whereby the infant supportingmember itself as well as the space above it are suitably heated. Thesupport 24 is pro-'-' vided with a pair ofpins 28 which are adapted to engageangle iron shelves 29 and 36 secured to the side walls I I and I2 upon which the entire assemblage maybe rocked to put the supportin pad 26in any desired angular position. 'This member is held in adjusted position by means of a finger 3|, Fig. 4, which goesthrough'a slot 32 in end wall I4and takes in the notches 33' along said slot, Figs. 2 and 3. Similarly the lower end of themesh support 24 is provided with afinger member 34 which takes into a similar slot and notchesinot shown) to adjust themember 24 and the hinged part 24' indifferent angular positions relative to thepart 24.

. This arrangement is such that thebabys support as a whole may be disposed at any desired angle to the horizontal and theportion 24 thereof may be disposed at any desired angle to theportion 24. At the same time the entire arrangement is such as to permit the reception of heat from below thepad 26. Acover 35 is normally placed over the rear portion ofthe'compartmenti 22, as'best shown in Figs. 1 and 12. This cover tends to retain heat toward the foot of thegbaby holding compartment of the bassinet while the part at the front, as indicated in Fig. 12, is open neitherto' the fair of the room or to an'oxygentent 36 which will be later described in detail To furnish the heat above indicated anelectric heating element 31, as best shown in Fig. 5, is carried in a substantial rectangle underneath a series ofguard plates 38, 39, 40 and M, located in the lower part ofchamber 22, as clearly shown in Fig.3. The guard plates above referred to receive the direct-radiation from theheating element 31. This effects heating largely by convection, which keeps the outside walls warn, thus preventing cold drafts, and dissipates theheat throughout the bottom portion of the chamber from which the heat rises to pass, through the openmesh supporting members 24,

24' and through and about the supporting pad As shown in the wiring diagram of Fig. 14 the mainsupplycurrent wire 42 goes to theheating element 21. Abranch wire 43 goes through amercoid switch 44 from which leads asecond branch wire 45 which passes throughmanual switch 46 to the second maincurrent supply wire 41. The mercoid switch is located within athermostat control box 48 which is closed byacover member 48 which gives access to the interiorithereof. Th'e thermostat is of a wellknown gas expansion type wherein theexpansion member 50 is connected by atube 5| with adiaphragm chamber 52 adapted to move apiston head 53 into engagement with alever arm 54 which has along arm 55 adapted to rock theholder 56 for themercoid switch 44 to turn the which the infant lies and the atmosphere above the infant to a desired temperature. When this part of the chamber is employed for receiving an infant just born this temperature of the pad upon, which it is to be laid and the atmosphere surrounding it should be substantially that of the body temperature surrounding it before birth, that, between 98 and 99 F.- It has-been found that to produce this temperature at the supporting-surface of the pad and in thelatmosphere above it, a maximum temperature below the pad and controlledby the thermostat should be around F. a I 1 Under most conditions, except when the apparatus, is used for resuscitation purposes, an

oxygen tent 62.will be employed and have suitably tempered oxygen delivered thereto. The oxygen tent is shown in detail in Figspl and 8. The tent comprises a top -63-formed of rigid material with. double flange members64 which support a set of flexible walls .65 adapted to ex-v tend through theopen portion 66 at -the front of the bassinet, as indicatedin Fig.1. A loop I32 is formed at the bottoms of the tent walls in which is inserted a formed wire I33 whichholds the bottom of the oxygen tent in position withinchamber 22. The severalwalls'of the flexible tent portion are provided with'transparent portions '6'! which gives the nurse a'ready view of the infant within thechamber 22 of the bassinet.

The top 63 of the tent is provided with a pair'of valveplates I34 and I35Iformedwith sets of openings I36 and I31, Fig. 9." The top plate I34 may be rotated bymeans of a handle I38. By

thismeans axventilatingtopaopening of greater or less extent, as desired,'may be provided. The oxygen. tentiissupported with its open bottom extending a desired distance intochamber 22 by means .of a.tubular member 68 which passes through a clamping"device 69 secured tothe side wall I2 of the bassinet and operatedby means of a thumb'screw 'IO whereby theoxygen tent 62 may be held in any desired position as adjusted for height.

The supportingmember 68 comprises a tube which is in communication-with an oxygen'de livery tube II extending-for some distanceim side of the tent,- withopenings 12 for-permitting flow of oxygen laterally from the tubeinto the tent. Aconnector member 13 on supporting mem'ber 68, Figs. 1 and 2, customarily is united with an oxygen supply tube I4. from either of twotanks 15 or I6 througha regulatingvalve 11 of well known construction. From the valve 11 the oxygen goes by means of apipe 18, Figs. 1 and 2, to a manifold passage way I9 controlled byavalve 66. In the course of its travel from valve 11 alongpipe 18 tomanifold passageway 19 the oxygen may be heated as desired, preferably by electric heating means, not

. shown. 'From the passageway I9- the oxygen gas passes through'a flow valve BI and thence through The oxygen is fed atransverse tube 84, Fig. 1, anddependingdoop 85 into avalve chamber 86, Fig. 6. A mve 81 controls the flow of gas fromvalve chamber 86 the valve'being controlled by a thumb screw 08;.

In the position or the valve of Fig. fi theoxygen' gas will pass directly throughpipe 89 throughopenings 90 and'9I into the top of a jar "and from opening SI through anopening 93 which leads to atube 94 connectedwiththe tube 14 here tofore described. The casting which forms thevalve chamber 96 has secured thereto acontainer 95 having therein a quantity of water, as indicated at 96 Fig. 6. When thevalve 81 is moved by thethumb screw 88 to a position for closing direct connection with pipe 8'9 the. oxygen will flow' through an opening. 91 and atube 98 to discharge: through a series ofapertures 99 into the body ofwater 96. The oxygen will bubble. through this water and pass through passageway: I to thetube 89. The reversal of the gas throughcontainer 92. atpassageways 90 and 9I results' in precipitation of any free water be entrained with the gas bubbles. ar-'- rangement not only supplies oxygen gas to the oxygen tent as desired but also suitably humidifies the oxygen and the atmosphere breathed by the'infant. .1

It may be desirable under certain circumstances to deliver fully free oxygen directly to the patient; For this purpose the tube I4 may be disconnected from the connector member I3 and connected the infant inhaler IOI, as indicated in Fig. 6, and the oxygen gas either as delivered from thetank or humidified may be administered directly 'to the infant. f

Associated with the same oxygen supply and control means as that'which supplies oxygen die reot to the oxygen tent or to the infant, is a resuscitator apparatus designated generally by the arrow and reference character I02. This resuscitator apparatus is that of Letters Patent No. 1,848,232 and No. 1,848,233, above referred to and need not be described in detail further than to point out that oxygen is fed to the main control valve I03 through a pipe I04 from the passageway 'I9. Further that the feed of oxygen from the control valve I 03 goesthrough pipe I05 to a feed pipe I06 which in turn connects with a flexible tubing I01, Fig. 1, having direct connection with a special inhaler device I08 which.fis substantially the same as the inhaler device disclosed in patent to myself and Swope, No. 1,848,- 232. The pressure of the gas forced under pres,-

sure into the lungs of the infant is controlled by a return tube I09, Fig. 1, which connects with tubing III). The tubing H0 in turn connects through a pipe III, Figs. 2, 3 and 5, which con stitutes the pressure. stabilizing mechanism of the resuscitator I02. This, as described in the said patents above cited, includes a column of water adjustable as to height. -A faucet H2 is adapted to drain off this water.

In the use of this resuscitator apparatus the special inhaler structure I08 is applied ovei th'e mouth and nose of the infant, and lever II3: co 1 1- nected therewith is operated to allow oxygen under pressure which is regulated as a safe pressure toflow into the lungs. The lever H3 is thus released and the doctor or nurse expels the oxygen I by pressure upon the chest and lungs of the infant. In this manner where prompt application of the resuscitator is made without undue shock, infants, whose life otherwise would quickly end, are resuscitated and saved.

which might.

Under certain conditions it may be necessary to remove from the breathing passages of the infant accumulations ofslime and mucus, which unless quickly removed might cause serious and even fatal choking. In order to have such an an paratus available for instant use I provide the construction indicated indetail in Figs. 1, 10and 11; A valve casing H4 is secured to the bottom wall I5 as indicated at H5 of Fig. 11. Within the casing are formed an outlet chamber and val-velIi normally blockingan outlet air passageway III, and an inlet chamber and valve II8 normally blocking aninlet passageway I I9. The valve chamber I'I8' extends to a very small opening I leading through the connector neck I2I to within a collapsible bulb I22. From the inlet passageway II9 leads a tube I23 which enters a deposit chamber I24 in a receptacle I'25, as clearly shown in Fig. 10, said receptacle being secured by clamping means I 26 to the post I5. From the chamber I24 leads a connectormember I21 which extends through the cover of the receptacle I some distance insidethe same and which is connected by meansof a tube I29 with a catheter suction tube I29. The catheter has secured thereto a looped member I30 which is adapted to hang the same upon a hook I3I fast on the bottom wall I5.

With this arrangement the catheter can be inserted into the throat or nostrils of the infant and by successive squeezings of bulb I22 the mucus or other clogging matter can be withfor whom any degree of shock might easily drawn. The valves H6, H8 of course prevent I any undue or dangerous pressure to the throat or mouth passages of the infant upon squeezing of the bulb. Where desired a small motor building up the desired negative pressure can 'be employed in place of the bulb I22.

:Among the advantages of my invention particularly to be mentioned are the provision ofimmediately available means for establishing the life of a new-born infant and safeguarding the lives of those new-born infants in any degree subnormal. Under even the best of hospital conditions the new-born baby comesto light in an atmosphere at a temperature far below the temperature under which the infant has lived to the time of birth. Generally speaking, bedding, blankets, or other articles in which the infant may be wrapped are at that lowered temperature. Contacts with air or other matter at those lowered temperatures are sure to produce a degree of shock. A strong and lusty baby can endure it without too serious consequences. Not, however, a premature or other subnormal infant,

prove disastrous.

bassinet organization the new-born infant can be placed upon a support and in an atmosphere heated to slightly above 98 F. where he will breathe air or oxygen-enriched air or oxygen at that temperature. This avoids that shook which with the premature or subnormal infant might result fatally. With the infant whose breathing does not establish itself this avoidance of shock in connection with the use of known resuscitator appliances tremendously increases the chances that normal breathing may be established and the life of the infant be saved. I I

But my resuscitator organization also provides the means for sustaining and building up the life forces of prematurely born infants or those who are subnormal for other reasons. For it contains all of the necessary means to treat any condition of a new-born infant or one whose slender thread of life easily may be snapped thereafter. In this connection the instant availability of oxygen while the infant is supported upon a suitably heated pad in a suitably heated atmosphere, either for direct delivery to the lungs or breathing of the infant or for enriching the atmosphere which the infant breathes, is of extreme im-.

or all of them may be used with the utmost dispatch while the infant is kept in a condition fully protected from shock. My invention is not merely the provision of oxygen-supplying means, resuscitator means and the like, but the provision ofthese means where any or all of them is and .areavailable for instant use upon an infant positioned, warmed and guarded so that any such use will be possible without complications resultv ing from shock" caused by other and extraneous conditions. 4 v v lclaimz, I v a H In a bassinet organization, a portable body member. forming an inclosed chamber, porous means therein positioned toward the center of the chamber for supporting an infant, thermostatically controlled electric heating means to heat said porous means and to maintain a predetermined "high temperature within the chamber,a source of oxygen supply, an oxygen receiving manifold, means for delivering oxygen from said supply thereto, means for controlling thedelivery pressure of theoxygen as it is delivered to the manifolcLia set'of piping to conduct oxygenfrom the manifold to the chamber for increasing the oxygen content of the atmosphere normally breathed by the infant, another set of piping for deliveringoxygen from the manifold directly to the lungs of the infant, said oxygen delivery being effective simultaneously through both sets of piping, and means associated with said directdelivering means to cause the oxygen therefrom to'
