Description

M. TINGLEFF LIQUID SAMPLING INSTRUMENT Filed June 15, 1931 MARIA/U5 Tux/51.5w" V lnventor' B W Atlorney Patented Get. 4, 1932 entree stares MARINUS TINGLEFF, OF SANDPOINT, IDAHO LIQUID SAMPLING INSTRUMENT Application filed June 15,

My present invention relates to improvements in liquid sampling instruments or blood-extracting devices, designed to withdraw blood, by pressure from within the body, and while the device or instrument is adapted for various purposes, it is especially neck of the bottle.

designed for extracting samples of blood from cattle and live-stock, for testing in the laboratory. in the process or operation of extracting the sample from the animal, the animal frequently becomes obstreperous, resulting in breaking of the bottle or receptacle and consequent loss of the sample. The primary object oi my invention is the provision of a casing or holder for the receptacle, which shields and protects the receptacle, and which holder forms the support for the hypodermic needle. Thus the instrument comprises essentially three separable elements, the bottle or receptacle, the holder, and the hypodermic needle, and these elements may be separated when desired or necessary, for cleansing, to insure sanitary condition of the device.

The invention consists in certain novel com- 1 binations and arrangements of parts involving the bottle, holder and needle, as will hereinatter be more fully set forth and claimed. In the accompanying drawing I have illustrated one complete example of the physical embodiment of invention wherein the parts are combined and arranged according to one mode I have thus far devised for the practical application of the principles of my invention.

Figure 1 is a perspective view of the instrument in closed position. Figure 2 is a View of the device showing the cap removed, but

with the needle in inverted position, whilev Figure 3 is a similar View with the needle in extended position and ready for use;

Figure 4 is a View of the holder showing the snap-catch or detent for retaining the bottle or receptacle in the holder.

Figure 5 is an enlarged sectional view of the holder, showing the bottle in dotted lines and retained therein, at line 55 Fig. 4;.

Figure 6 is a detail view of the hypodermic needle, detached.

Figure 7 is a perspective View of the closed head of the holder, as at line 7-7 of Figure 4. Figure 8 is an enlarged detail view oi. the

1931. Serial No. 544,504.

head portionof the holder showing the neck I of the bottle and thevent ports.

The bottle or receptacle 1 may be of any usual form, butis here shown as cylindrical,

and provided, just below its open mouth, with an exterior, annular groove 2 encircling the The mouth-end of the bottle is slipped into the open end of a cylindrical holder or casing 3 fashioned of suitable material, and the open end of the holder is slitted to form a blade 4:

having at its free end or edge a snap catch 4 that projects inwardly of the holder and is adapted to fit snugly up against the bottom edge of the bottle, as indicated in Figure 5. i

The blade 4 is preferably integral with the holder, and is of resilient material in order that the bottle may he slipped into the open end of the holder, (bypressing outwardly the snap-catch 4) and after the bottle is proper- 1y enclosed in the holder, the snap-catch holds the mouth of the bottle in close contact with the under face of the head 6 that closes the, upper end of the holder.

In its side walls the holder is provided with one or more windows or slots 5 that terminate near the ends oitthe holder, and permit inspection of the contents of the bottle While in the holder. vThese windows also provide for ingress of the thumb o'rgifinger, which are pushed into the annular grobve 2 of the bottle as a finger-hold.

Thus upon inspection of Figure 8 it will be apparent that the finger nail or thumb nail may be inserted in one of the windows and pressed against the annular groove 2, and then by pressure, the bottle may be slipped out of its holder, past the snap-catch 4, without danger of spilling its contents.

The under-side of the fixed head 6, as seen' in Figures 7 and 8 is corrugated at 7 to form radial ports, and as the mouth of the bottle fits snugly against the underside of underface of the head, these ports form vents to the atmosphere from the bottle whereby blood pressure within the body of the animal will operate to force blood through a hypodermic needle 8, when the latter is supported in correct position in the head 6.

The needle is tubular as usual and provided with the customary point 9 that is jabbed or inserted into the body of the animal, for the extraction of the blood sample.

The head 6 of the holder 3 is fashioned with 5 an externally threaded boss 10, an orifice 11 and an internally threaded part or socket 12, the latter forthe reception of complementary parts on the needle.

As best seen in Figure 6 the needle .is

10 equipped with a plug or stopper 13 secured thereon in suitable manner, and'the ends 14 and 15 of this stopper are vthreaded ,for alternate or selective use with the threaded socket 12 of the holder. In Figure 2 the threaded end 15 of the stopper is screwed into the socket to hold the 2nee'dle-in inverted position within the holder .or its :contained bottle, While :in Figure 3thethreaded end 14 .is screwed into the socket -1 2 with the needle .in operative position for use.

A cap i161is provided with interior threads that screw down on the exterior threads of :the boss .10 to protect or shield the needle when in position ofrFigureQ.

.Having :thus .tully described my invention, what I claimas new and desire tosecu-re Letters Patent =is.:

1. The combination of a bottle holder :adapted .to receive a *bottleand having-ahead 'm .at one lend, :a removable, "tubular :needle mounted in the head and projecting into the holder, means for retaining an open-:mouth bottle against the :inner faceof said head, and said inner face having vent grooves therein for venti-ng the interior of the'bottle.

Q. The'combina'tion-of abottle holder open at one end, a head at the other end of the holder, a removable, tubular needle mounted in the head and projecting into the holder,

, :an integral resilient :snap spring within the open end oftlie holder for retaining the'open mouth of a ibottle'aga'inst said head, and said head having vent grooves in its inner face .to Vent the interior of the bottle.

-15 In testimony whereof I atfiX any-signature.
