Product Components

Penn-Century

Small Animal Laryngoscope - Mod el LS -2 is based on pediatric laryngoscope components that are

modified extensively for use in small animals. The Laryngoscope consists of:

1. A silicon-coated handle that contains a LED light source and 3-volt lithium battery (included)

2. A detachable blade assembly with a stainless steel fiber-optic bundle, housed inside a light pipe

3. A metal blade tip attached to the end of the fiber-optic light pipe. The blade tip is hand-made and is
sized for use with a specific animal. It is designed to push aside the animal’s tongue

NOTE: When using the device, or connecting or disconnecting the blade assembly, do not grasp or
push on the fiber-optic light pipe or metal blade tip, or use either for leverage. You may bend or
damage them.

Assembly and Use of the Small Animal Laryngoscope

Insert blade green “hooks” at bottom of blade
assembly into metal bar at top of handle as
shown. Push down on rear of blade assembly to
click it into place and turn on light.

1. To attach the blade assembly to the handle:

- Locate the two green hook-like prongs at the bottom of the blade assembly.

- Slide these “hooks” und er the metal bar on the top, front of the handle as shown in photo above.

- Firmly push down on the back of the green base to lock it in place. (Note that there is a metal sphere on

each side of the blade assembly that will fit into tw o spherical cavities at the to p of the handle to hold it
securely.) Once the blade assembly snaps into pla ce , the light will come on.

The blade tip of the Model LS-2 is hand-made and is sized for
use with a specific animal. Shown left are two examples of
blade assemblies with blade tips for Mouse (LS-BA-M) above,
and Guinea Pig (L S-BA-GP) below.

Additional Blade Assemblies are available for purchase for use
with different animals and may be attached to either Penn­Century Small Animal Laryngoscope Model LS-1 (discontinued)
or Model LS-2 (current model.) (Note: Will not fit any other
laryngoscope handle.)

2. Use in the animal: It is not necessary to insert the entire blade tip into the mouth of the animal. Insert only
the very tip of the blade only in the animal’s mouth. The tip is intende d onl y to push aside the animal’s
tongue. Do not forcefully bend or manipulate the blade tip as this may cause it to break. Note that the blade
is sharp and should be handled with care.

3. To turn off the light and save battery power, detach the blade assembly from the handle when not in
use. With your thumb, push up firmly on the rear of the blade assembly, or grasp the square green base and
push it up from the rear.

4. Care, cleaning and disinfecting. Please note that the Penn-Century Small Animal Laryngoscope – Model
LS-2 is made from modified components from two different manufacturers. Detailed instructions on the
materials that may or may not be safely used to clean and disinfect the blade assembly and handle are
