IApplicationfApriYlfi, 194,5,*senarnaissacis further object of thisinvention is to provide a supportoffthiskind which is of simple conlet w iit i {l'qthefforegoing obj ects" and others which may ereinai'tenmorepfully appear, ;the invention construction so that it-can be built sturdily and at .Qarrangement"of parts;asWillibe*morespecificellly gre fjerred to and illustrated in the accompanying "drawings," but "it isf'to be understood that changes, variations, "and modifications may be resorted to which .l-fall .within ,ithewscope of the invention as claimed.

In the drawings;

Figure 1 is a top plan view of the apparatus,

Figure z is a side elevation;

Figure 3 is a sectional viewi taken on line 3- 3 of Figurei2,

Figure 4 is a sectional view taken on line 4-4 9 Figure 3, v Figure 5 is a'detail'of' one end of the-arm rest board,

Figure 6 is a bottom plan view of the same end as Figure 5, t

Figure 7 is a sectional view taken on line 1-1 of Figure 1,

Figure 8 is a sectional View taken on line 88 of Figure 7, and

Figure 9 is an end elevation taken on line 9-9 of Figure 3. l

Referring now to the drawings the numeral l indicates the arm rest board having the spaced upper and lower members I l and [2 respectively. The board In may be fastened to an operating table and extend outward or at right angles thereto.

Extending through the opening I 3, and arranged slidably therein is a member M which may move to and fro and back and forth in the opening I3 and arranged on the member I4 is a slide l which completely encircles the member 14 and has positioned on its top side It a, support or lesior supporting injectionelements in a con- Sis ts of theljgnovelltconstruction, combination and 5 Claims. (015311-) 2 =standard ll, said standard having bifurcations l8 and 19 at its upper end for the reception there- "betweenof theprojecting member 20"which is arrangedwith a supporting top 2| for retention thereon of a platform=like member 22.

The bifurcations l8 and I9 and the member 20 have'holes therethrough for the reception of a bolt23'and,,preferably, a wing nut on the end of ,"said bolt to hold said platform in adjustable stafltionary position.

,Positionedon said platform 22 are the resilient members'18, 29930 and" 3| which are of-the flat spring type, .quite resilient, and arranged forthe reception and retention of any number of the syringes Hand- 33.

""The syringe 32 hasat its discharge end a threeway valve. to which'bothof the syringes are connected. "This valvepermits the contents of Leither or both. of the syringes to be released into .lthe meets for injectionthrough the needle 36. The reservoir 31 is preferably made of a transparent substance so that if there is air in the .,,line it may be eliminated before the injection ctakes place. The transparent reservoir 31 has the additional advantage of indicating when the needle has penetrateda vein, instead of a muscle, l,becauselthebackefiow of blood from the vein will appear in the reservoir, 7

On the slide l5, at the foot of the standard l1, reterringeespeciallyrto FiguresW and 8, there is provided. a means to releasably retain said slide against the member 14, said means consisting,

.,preferab, y, of athumblscrew 38 having a disc 39 eat the forward end of its shank 45 and a threaded tinsertltoreceivethe threads of said shank. It is apparent thatpressure on .the disc. will hold the slide against lateral movement with reference to the member l4.

Adjacent the board I0 and arranged for projection of the member l4 therethrough is a brace 45, Figures 3 and 9, which will prevent swaying motion of the member M. The brace has an overlapping portion 46 which slidably rests on top of the upper arm rest member ll while its vertical portion 41 is channeled to threadably receive the shank 48 of the thumb screw 49, the disc 50 of which will act against the member l4 when pressure is applied.

From the vertical portion extends a lateral projection 5| which has positioned at its outward end another thumb screw 52 and when screwed upward the disc 53 will impinge against the underside of the lower member I2. The double action of the twothumb screws will effectively prevent swaying of the member l4.

At one end of the member I4 I have provided a rotatable lock or catch 54 which is releasably held by the screw 55, and when released, may be turned to a vertical position, as shown in Figure 1, thereby preventing the member M from sliding away from the arm rest H when there is occasion to tilt the operating table.

Figures 5 and 6 illustrate, in detail, the construction of one end of the arm rest board, the upper and lower members H and I2, respectively, thereof having the spacer 60 between them. The opposite end also has a similar spacer between them. v V

The end legs 6i and 62 are fastened to the upper member H and the spacer 60 in any suitable manner, the legs being re-inior'ced by an angle and reinforcing plate 63, which also is attached to and supports the lower member l2, as clearly shown in the two above mentioned figures.

I have used the word board in a broad sense, wood, metal, plastic or any other suitable material may be used for making the various parts.

While this invention may be used in administering various types of anaesthesia it is particularly adaptable for giving an intravenous sodium pentothal anaesthetic, and it has the added advantage of easily being removable from one side to the other of the arm board or the operating table. The arm board is generally fitted to the surgery table by means of the legs 6| and 62 which fit into slides that are a part of the standard table.

The operation of the invention is made easy by its simplicity and is so constructed that one anaesthetician can perform the duties which usually require two such experts.

First, the arm board ii) is fastened to the surgery table, the member l4 positioned in the opening of said arm board may be longitudinally slid to the desired position. It may also be moved laterally of said arm board as may be the slide it, thus furnishing a dual movement in this direction. The platform 22 may be tilted to any desired angle, all of these movements cooperating to allow the needle 36 to be manipulated at any desired point. Through operation of the threeway valve 34, either or both of the syringes may be brought into play.

What I claim is:

1. An apparatus for giving an anaesthetic comprising, an arm board, upper and lower members of said arm board, spacing elements to maintain said members in spaced relation, 2. member slidably positioned between said upper and lower members, and a means on said slidable member to hold ananaesthetic container.

2. An apparatus for giving an anaesthetic comprising an arm board including upper and lower members, spacing elements to maintain said members in spaced relation, a laterally extending member slidable longitudinally between said upper and lower members, means holding said latter member against all but sliding movement relative to said arm board, a. second slidable member on said first slidable member, means locking said slidable members against relative movement therebetween, and an anaesthetic container supporting platform pivotally mounted on said second sliding member.

3. An apparatus for giving an anaesthetic comprisin an arm board including upper and lower members, spacing elements to maintain said members in spaced relation, a laterally extending member slidable between said upper an lower members, bracing means slidable on sai upper and lower members and said slidable mem ber for holding said sliding member against a but sliding movement on said arm board, looking means fixing said arm board, said sliding member, and said bracing means against sliding movement therebetween, a second slidable member on said first slidable member and an anaesthetic container supporting platform rockably mounted on said second slidable member.

i. An apparatus for giving an anaesthetic comprising a slotted arm board, a member slidably positioned in said arm board, a sliding clamp engaging said member and said arm board for fixing said member and said arm board together, a second slidable member on said first slidable member, and a means onsaid second slidable member to hold an anaesthetic container.

5. An apparatus for giving an anaesthetic comprising a slotted arm board, a member slidably positioned in said arm board, a clamp slidable on said arm board and said member, a second slidable member on said first slidable member, a platform rockably mounted on said second slidable member, and resilient clamping means Ion said platform for securing anaesthetic con- The following references are of record in the file of this patent:
