BLOOD TRANSFUSION BOARD I Filed Sept. 1, 1958 fi v9.1.

cf /9 I? 53 FranWZj/w INVENTOR ATTORNEYS Patented Mar. 26, 1940 UNITED S A ES) TE OFF My invention comprehends a blood transfusion board and has as one of'the principal *objects thereof the provision of such a board equipped with adjustable arm rests whereby the arm of the donor maybe adjusted relative, to the arm of the doneeorpatient.

is simple in construction, durable in use, em-

cient in operation and economical in manufacture.

Other objects anda'dvantages willbe apparent from the following description, appended claims and annexed drawing. l

15 Referring to the drawing wherein like refer; ence characters designate like parts throughout the several views: v

Figure 1 is a perspective view of my invention. Figure 2 is a perspective view of my invention illustrating the latter in up-side-down position. Figure 3 is a side elevation of vmy invention partly in section.

Figure 4 is a detail vertical sectional view through one of the'arm rests and supports there!- 25 In practicing my invention I provide a board 5 of an elongated rectangular configuration in plan and formed with upper and lower faces '6 and 1 respectively. The lower face I has secured there-' on, adjacent the ends thereof, pairs of spaced brackets 8 in which are slidably mounted arms 9, the outer ends of which are right angularly disposed. I

Said arms are adjustable relative to thebrackets 8whereby to support theboard 5 between a I pair of operating tables or the like on which rest the blood donor andthe donee respectively.

Q q The board 5v is provided with a series of openings 10 near. the diagonal opposite ends and'are utilized for mountinga pair of spaced arm rests l5 on the board as hereinafter more fully de-@ scribed. Each of the openings are threaded and one of the openings of each series hassecured thereinthe threaded lower end of awinged support I I formed with an abutment collar and fash-.

ioned with a socket l2 for'accommo'dating the lower'end of a pin IS. The upper ends of the pins 13 extend within cul-de-sacs formed in downwardly projecting sections fashioned on the arm rests IS. The upper and Another object of my invention is to provide a device of the above described character which I4 I integrally lower ends of the pinsare provided with circ'um- "ferentially extending igroo'ves receiving therein the ends of set screws carried by the supports H p and sections I l respectively for maintaining the arm rests connectedto the supports and board as 'clearly'illustrated in Figure 4.

It is. tobe understood thatvarious lengths of pins i3 may be used whereby to adjust the height of the arm rests'relative to the upper face 6 of the board and that the threaded ends of-the vmembers ll may besecured. in any one of the respective seriesof openings I0 whereby to effect adjustment of the arm 'rests relative'to each other. 1 m

From theforegoing it will be apparent that by the ;use of my device the arm of the donor 15 and the armof the dome may be adjustedrelative to each, other in a desired manner to efiect ,a-blood transfusion. therebetween in the. usual manner. H v

It is. to be distinctly understoodthat various 9 changes and modifications in the construction and arrangement of the parts maybe resorted to without departing from the spirit of the invention or scope of the appended claims.

WhatIclaimis: 1

.1. A device of the character described, comprising, an elongated board fashioned with series of openings near the diagonal opposite corners of said board a support member detachably secured in an "opening of each series and adapted .30

to be selectively positioned in theremaining g openings, an arm restmounted on each of said members andadjustable with thelatter and with respect. to saidjboard for varying the distance between said rests, andreplaceable means connecting saidrests to said members wherebyto vary the height of said rests relative to said board. l 1

2. A device of. the character described; comprising,.an elongated board fashioned with series 40 of openings near the diagonal opposite corners of said board, a supportmember detachably secured in an opening of each series and adapted to be; selectively positioned in the remaining openings; 5 an arm rest mounted on each of said members and adjustable with the latter and with respect. to said board for varying the distance between. said rests, and replaceable pins of diflerent lengths selectively connecting. said rests to said members to vary thedistance therebetween. 1 a l BENNIE V.
