AUXHJARY BLOOD CIRCUIT Henry Benjamin Ray, Chicago, Ill.
Application September 22, 1952, Serial No. 310,839
3 Claims. (Cl. 128-214) The present invention relates to an auxiliary blood circuit and it consists in the combinations, constructions and arrangements of parts herein described and claimed.
Generally there is provided an apparatus which, in eifect, constitutes an auxiliary blood circuit and which consists of a device which forms an observation window, the latter comprising a pair of glass plates interconnected at their side edges in spaced relation to each other and provided with an inlet portion at one end and an outlet port at the other. Means is provided for connecting the observation window to the live blood stream of a specimen by means of tubes and a pair of hypodermic needles. There is also provided means for holding a portion of the flow of blood through the device so that the same may be examined by placing the observation window upon a microscope stage whereby the blood corpuscles may be photographed in absolute clarity.
It is accordingly an object of the invention to provide a noval auxiliary blood circuit device having a novel observation window therein.
Another object of the invention is to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and elficient m use.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:
Figure l is an elevational view of an embodiment of the invention,
Figure 2 is an enlarged sectional view taken along line 22 of Figure 1.
Referring more particularly to the drawing, there is shown therein an auxiliary blood circuit of the character set forth comprising an inlet hypodermic needle 10 which is connected by a tube 11 to a Y-fitting 12. One arm 13 of the fitting 12 is connected by means of a tube 14 to a stop cock 15 which is, in turn, connected by a tube 16 to a T-fitting 17.
The other arm 18 of the fitting 12 is connected by a short tube 19 to a stop cock 20 which, in turn, is connected by a tube 21 to an injection port 22. The injection port 22 is connected by a tube 23 to an inlet fitting 24 of an observation window generally designated at 25. The window 25 is provided with an outlet fitting 26 which is connected by a tube 27 to the T-fitting 17 The fitting 17 is connected by a tube 28 to a tap gen- States Patent 2,697,435 Patented Dec. 21, 1954 erally designated at 29 and which tap 29 is connected, in turn, by a tube 30 to a stop cock 31 which is then connected by a tube 32 to an outlet hypodermic needle 33.
The observation window 25 consists of a pair of flat transparent plates 34 which are held in spaced relation to each other by comparatively short side walls 35 providing therebetween a confined space 36.
In operation, it will be apparent that when it is desired to test or photograph a specimen of blood from an animal, human or the like, it is only necessary to insert the hypodermic needle 10 into one portion of such animal and the discharge needle 33 into another portion thereof whereupon a flow of blood will start to travel through the device. By manipulation of the proper stop cocks 15 and 20, a portion of such flow of blood may be trapped in the observation window 25 and temporarily locked therein by closing the stop cock 31 and the stop cock 20. The window 34 may then be placed upon the stage of a microscope and visually observed or photographed as the case may be.
While but one form of the invention has been shown and described herein, it will be apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
What is claimed is:
1. A device of the character described comprising a conduit, an inlet needle at one end of said conduit, an outlet needle at the other end of said conduit, a by-pass conduit connected into said first conduit, and an observation window in said by-pass conduit.
2. A device of the character described comprising a conduit, an inlet needle at one end of said conduit, an outlet needle at the other end of said conduit, a by-pass conduit connected into said first conduit, and an observation window in said by-pass conduit, said observation window comprising a pair of spaced transparent plates sealed at their side edges and having an inlet fitting and an outlet fitting, said fittings being connected into said by-pass conduit.
3. A device of the character described comprising a conduit, a T-fitting in said conduit, a Y-fitting in said conduit, 21 by-pass conduit interconnecting the T-fitting and the Y-fitting, an inlet needle at one end of said first mentioned conduit, an outlet needle at the other end of said first mentioned conduit, a stop cock in said first mentioned conduit between said T-fitting and said outlet needle, a stop cock in said first mentioned conduit between said T-fitting and said Y-fitting, a stop cock in said by-pass conduit, and an observation window in said bypass conduit between said last-mentioned stop cock and the T-fitting.
