BETTY ,4. w r/w/va BY 7 Patented May 18, 1948 UNITE-D STATES PATENT OFFICE v 'rns'r TUBE HOLDER Betty A, Yan Hyning, Akron, Ohio Application March 11, 1947, Serial No. 733,807

2 Claims. (01. 248-230) are more common in recent years, often being used to relieve shock. In giving the injection or transfusion, the liquid containing bottle is mounted on a standard and a. hose extends from the bottle to a sterile needle. It has been a problem to keep the needle sterile until use. One manner of doing this has been to secure a test tube with adhesive to the standard and to place the needle in the test tube. It is a constant annoyance to mount and remove a test tube in this manner.

Heretofore test tube holders other than adhesive have been provided for laboratory use but these do not readily adapt themselves to use with intravenous injection or transfusion apparatus. Moreover, known test tube holders are often expensive, hard to handle, and are not adapted to the removal of the test tube, as for sterilization, without unclamping.

The general object of this invention is to avoid and overcome the foregoing, and other disadvantages of and objections to known types of test tube holders and to provide a test tube holder of the above type that is particularly adapted to be used in conjunction with intravenous injection and transfusion apparatus.

Another object of the invention is to provide a sturdy, light weight, easily produced test tube holder.

Another object of the invention is to provide an inexpensive, yet strong, test tube holder adapted for adjustable engagement with and support by a standard, which holder has a minimum of parts.

A further object of the invention is to provide a test tube holder which provides a safe receptacle for a test tube that is easily placed therein or removed therefrom.

Another object of my invention is the provision of a test tube holder made from a single sheet metal stamping.

The foregoin and other objects and advantages of the invention, which will be made apparent as the specification proceeds, are achieved, broadly speaking, by the provision of a test tube holder that is formed from a single sheet metal stamping which has a pair of juxtaposed strap portions which are adapted to engage with a standard, and which has a plurality of finger portions extending from a tubular section thereof in closely associated relation; means for securing such finger portions together at their ends to form a basket therefrom and means associated with the strap portions for securing the holder to a standard.

Reference now is made to the accompanying drawings, wherein:

Fig. 1 is an elevation of a test tube holder embodying the principles of the invention;

, V Fig. 2 is a plan of the holder of Fig. 1;

Fig. 3 is an elevation. of one use of the holder of the invention; and v Fig. 4 is an elevation of a stamping from which the test tube holder of the invention is made.

Attention now is directed to the detailed structure disclosed herein and a test tube holder, generally indicated by the numeral Ill, is shown. As a salient feature of the invention, tube holder I0 is formed primarily from a single sheet metal stamping which has strap portions l I and I2 that are joined together by a center strap section [3 that has a plurality of centrally located, laterally spaced fingers l4 extending normally therefrom. To form the holder ID from the stamping, the center strap section I3 is first bent to looped or tubular form and retained in that shape by a bolt I5, or equivalent means, which extends through the strap portions H and I2 immediately adjacent the center section I 3. This, of course, places the strap portions l I and 12 in juxtaposed relation.

A standard engaging arm or section I6 is formed in the holder II] by bending opposed sections of the strap portions II and I2 in opposite directions to form mated semi-circular or other shaped loops. The ends of the strap portions II and I2 are adjustably and removably secured together by conventional clamp means, such as a bolt I1 and Wing nut I8.

The test tube holder Ill may be completed by securin the inwardly bent ends 2| of the fingers l4 together by a rivet l9. In all events, the ends 2| are bent in so as to nest together as shown in Fig. 1 either before or after the section I 3 is rendered tubular, as desired. The holder Ill, it will be noted, provides a good sized tube receiving basket portion into which a test tube can easily be placed, or from which it can likewise be easily removed. Thus the holder I I] is sturdily formed from a single sheet metal stamping and is adapted for ready engagement with a mounting standard by removing the nut I8 and The needle 35 on the end of the hose 33 is placed in asterile.

test tube 34 carried in the holder I!) and the plug 36 conveniently rests against the. mouth of l the test tube to seal the tube. and needle against movement of foreign matter into the tubethere by better to keep the needle sterile. holder I9 is set at a predetermined spot on the arm'3l for receipt and retention of the sterilized needle as will beunderstood Also, it Will. be recognized that the. basket-dike support for the testtube'ii l permits it to be lifted out Without unelamping anything. This facilitates sterilization of thetube and eliminates any question or danger of clamping the tube too loosely or too tightly.

The holder IE! is easily adjusted vertically of its mounting arm by loosening the nut i3 and sliding the holder to its desired location, after which the. nut. I8 is tightened to retain the holder in its proper. position. As the test tube holder basket and its mounting arm are integrally formed, the unit is sturdy, andrequires a minimumof assembly work all of which can be performed by unskilled labor. e

The holder ill may, of course, be formed from any suitable kind of meta1,..whereas the test tube receiving basket may be of any desired shape or size. Also, the bent ends 2| of the fingers it can be secured together by any desired device or, insome instances, merely be physically adjacent each other without any definite securing member.

. '4 described herein in detail. However, it will be understood that the scope of the invention is not limited to that example given herein, but that modification may be resorted to within the scope of the appended claims.

What is claimed is:

1. A test tube holder comprising a sheet metal stamping having a substantially annular strap portion for engagement with a support and having a plurality of finger portions extending from a tubular portion thereof, said finger portions b ing provided with end sections which are bent i towards the center of the tubular portion and a e nested together, means for securing the nested end sections of said finger portions together for formation of artube receiving basket, means for retaining-said tubular portion in that shape, and

The

In accordance with the patent statutes, one

complete embodiment of the invention has been 11169115101 removably clamping said annular strap portion to a support.

2. A holder for test tubes and the like, said holder, being made from a single piece of sheet metal and including, an elongated basket-like portion, a strap forming the mouth of the portion, integral fingers extending from the strap, the ends of the fingers being bent over and secured togetherto form the bottom of the basketlike portion means securing the strap together adjacent the basket-like portion, the ends of the strap being extended and shaped to jointly surround a standard, and means for adjustably clamping the extreme ends of .the strap together to secure the holder to a standard.
