The 1:1 model of the head is in cross-section to show the skull, brain and spinal cord, nasal and pharyngeal cavity, larynx, tongue, oesophagus, and trachea. It is hand-painted and numbered with labels to identify different anatomical components. It is set onto a backing board of black pine.Relief on metal plaque affixed to base of backing board.

An instrument designed to remove swallowed foreign objects. The end containing horsehair is pushed past a foreign body in the oesophagus then expanded and withdrawn, bringing the foreign body with it. This probang is constructed from metal and horsehair. The metal is coiled to enable flexibility and the proximal end has a metal finger grip for support. The distal end comprises a smooth metal tip and the strands of horsehair are designed to scoop strands of foreign material from the patient's pharynx.anaesthesia, probang, oral, horsehair, lidcome state hospital, dr sharkey, obstruction, airway

NJ Phillips was the first Australian company to invent a drench gun that overcame the problem of drench going the 'wrong way' down the throat and onto a sheep’s lungs. This was the drench gun that they developed. It had an ingenious double action on the handpiece. The first squeeze projected a long nozzle that went right down the oesophagus before delivering the dose of drench automatically once this was in place. It also had a readily adjusted dose lever seen at left which minimised overdosing. This company dominated the market for many yearsSilver metal with black finishing drench gun. Minimal curvature tips on gun protrude from the body. Features a thin squeezable trigger to the rear of the body. The main bulk, which the trigger is squeezed towards, has badge which reads “Manufactured and designed by N.J. Phillips Pty Ltd, Sydney” in circular design. On top of this body is a large silver chamber in which both tips meet. This chamber is for the liquid to be transferred from the tube and into the tip of the drench gun for delivery onto the ewe’s tongue. The small section of tubing still attached has a yellow/orange appearance from remanence of drench which would have been this colour.Right circular lettering: MANUFACTURED/ & DESIGNED BY/ N.J.PHILLIPS PTY.

There are several different designs of drench guns within the NWM Collection that show the change in their development over time. On the left side of this gun white paint indicates the adjustable dose lever. It is a sliding scale from 10 to 0 cubic centimetres of liquid (now typical measure in millilitres). It also has a small and straight tip suggesting this gun was typically used for dosing Lambs as opposed to ewes. The manual adjuster helped to minimise cases of overdosing which can be fatal for livestock while the additional curvature helped to ensure the liquid reached the desired location within the sheep’s mouth. This desired location is on the left rear of the sheep’s tongue (from the sheep’s point of view) as this is where the oesophagus is located. The main risks are that drench may be delivered into the lungs via the trachea or “windpipe”, which can also prove fatal. The opening to the trachea which leads to the lungs is in the middle of the back of the throat. Another risk is the throat can also be damaged due to rough handling.Silver metal with black finishing drench gun.
