Abstract

A liquid feed injector for young animals and particularly calves comprises a collapsible reservoir and a rigid probe or feed tube connected by a relatively short length of flexible tubing. A fitting or closure cup for the reservoir is provided with an outlet nipple about which the flexible tube is attached and sealed. The construction facilitates the one-handed manipulation of the feeder while holding the animal'"'"'s head with the other, the flexible tube acting as a shut-off valve during manipulation for placing the tube in the animal'"'"'s throat. The reservoir may be flattened or rolled with the one hand during discharge of the fluid.

Claims

1. A device for the manual feeding of fluids to animals which comprises:

a stiff esophageal probe tube having a protective enlargement at its discharge end;

a flexible and collapsible fluid reservoir having a relatively rigid outlet collar;

a detachable outlet fitting on said collar having an outlet nipple extending therefrom; and

a short length of flexible tubing fitted on said nipple at one end and on the inlet end of said probe at the other leaving a short length of free tubing therebetween affording swinging movement of said probe with respect to said nipple;

said device being so constructed and arranged and the free length of said flexible tubing being sufficiently short that the tubing is collapsed and the passage therethrough closed by the swinging of said probe through a substantial angle from its unbent position whereby the passage of fluid therethrough is prevented.

2. A device for the manual feeding of fluids to animals as set forth in claim 1 wherein said reservoir is oblong in one plane and generally diamond shaped in a plane at right angles to said one plane and affording its being rolled up along said one plane during collapsing of the reservoir.

3. A device for the manual feeding of fluids to animals as set forth in claim 1 wherein said reservoir adjacent said outlet fitting is smaller than said outlet fitting.

4. A device for the manual feeding of fluids to animals as set forth in claim 1 wherein the closed end of said reservoir is necked in transversely to provide a grip for use during manipulation of the device and the squeezing and emptying of the reservoir.

7. A device for the manual feeding of fluids to animals as set forth in claim 1 wherein the free length of said tubing is about 21/2 times the internal diameter of the tubing.

8. A device for the manual feeding of fluids to animals as set forth in claim 1 wherein said probe is substantially longer than said reservoir.

5. A device for the manual feeding of fluids to animals which comprises:

a stiff esophageal probe tube having a protective enlargement at one end;

a flexible and collapsible fluid reservoir having a rigid outlet collar;

an outlet fitting constructed for attachment to said collar and having an outlet nipple extending therefrom; and

,

a short length of flexible tubing connecting said probe to receive fluid from said reservoir, said tubing affording the turning movement of said probe and the reservoir toward one another and the length of the tubing being sufficiently short and being constructed and arranged so that the bending of said tubing by turning of the probe and reservoir toward one another collapses the tubing wall and shuts off the passage therethrough to prevent flow of fluid from said reservoir, said fitting and said collar being constructed and arranged for providing a hand grip for holding the probe and the reservoir together during manipulation of the probe with the passage from the reservoir closed, whereby the operator may manipulate said device with one hand.

6. A hand device as set forth in claim 5 wherein said reservoir if of diamond configuration in one longitudinal section whereby the probe may be turned back close to the reservoir for facilitating the gripping of the reservoir and probe by one hand.

9. The method of feeding liquids to yound calves or other yound animals by utilizing a collapsible reservoir and rigid esophageal tube which comprises:

providing a short length of flexible tubing connecting the reservoir and the esophageal tube;

filling the reservoir with liquid feed;

swinging the esophageal tube about the flexible tubing nto a position toward the reservoir to bend and close the flexible tubing and holding the reservoir and tube together with one hand to maintain the tubing closed;

holding the animal'"'"'s head in position with the other hand and inserting the esophageal tube into the animal'"'"'s esophagus;

releasing the esophageal tube and moving the reservoir into general alignment with the tube to open the passage between the tube and the reservoir, and

squeezing the reservoir to force the liquid feed into the animal'"'"'s esophagus.

10. The method of feeding liquids to young calves or other animals as set forth in claim 9 including the step of rolling the reservoir upon itself during the squeezing thereof to empty the liquid from the reservoir.
