This is a convenient instrument for extracting poisonous substances from the stomach. It is also highly useful for administering medicines and injections, and if fitted with several tubes, one may suffice for animals of any size. It consists of a syringe, a, with a side opening at b, and another at the bottom d, as shown in [Fig. 16]. For injections, [Fig. 15] is used, and
the end of the syringe is placed in a vessel containing the fluid, when a probang or injection-tube is screwed on to the side opening at b, through which the fluid is forced into the stomach or rectum, as may be required. The probang should be a tube of thick but elastic leather, and it may be passed into the mouth, through an aperture in a block, placed on edge between the teeth, which is easily done while a person holds the head of the animal firmly.
Choking
Is frequently relieved by some of the following expedients.
The use of the probang or whip-stock, mentioned under the head of remedies for Hoven, by which the root is forced into the stomach.
A soft root may be crushed so as to allow of swallowing, by holding a smooth block against it, and striking with a mallet on the opposite side.
If within arms-length, the root may be removed by hand.
