1. INTENDED USE
The Instavac® is a portable aspirator which uses suction as a means to withdraw uids or foreign
bodies from a patient. Its primary intended use is as an aspirator to be used to help evacuate saliva,
mucous, vomit or other aspirant from the mouth and/or airway to allow adequate respiration or
ventilation of the patient and also as a pleural and wound drainage device.
NOT SUITABLE FOR USE IN THE PRESENCE OF FLAMMABLE ANESTHETICS ONLY

7. INSTRUCTIONS FOR USE
PRIOR TO INITIAL USE
®
Upon receiving your new Instavac
working order and that no damage has occurred during shipment.
, perform the following initial tests to ensure that your unit is in good
1. Visually inspect all components for physical damage that may have occurred during shipping.
2. After removing all components from their cartons, insert the backpole assembly into the back of the
Instavac® base.
3. Align the two “collection mounting brackets” located at the top of the backpole assembly towards the front
of the unit.
4. Tighten the 10-32 set screw located at the back of the base assembly with a 3/32” Allen wrench.
5. Connect the tubing from the bottom of the backpole to the safety overow trap assembly.
6. This unit comes with a detachable power cord. Attach power cord to the appliance outlet located on the
bottom of the unit before plugging unit in. The power cord is to be used for mains disconnection. Plug the
power cord into an electrical outlet. Turn the unit on (I) and listen to verify that the pump starts.
7. On Intermittent Model (756000) switch the unit to “CONSTANT” suction using the “MODE SELECTION”
switch. Plug the vacuum port located at the top of the backpole and adjust the vacuum level by turning the
vacuum regulator knob. Verify that the vacuum gauge reects a change in vacuum level while turning the
regulator knob.
8. Depress the “POWER” switch to turn the unit OFF (O).
9. Place a collection canister bracket (ring) in the mounting bracket of the backpole assembly or pedestal stand
and insert a collection canister.
The Instavac® will use any collection device. However, if you are not using an Ohio Medical 1200cc disposable
collection canister, make sure that the collection device being used is equipped with a safety overow
mechanism to protect the pump from accidental overow.
Ensure that you have the appropriate collection device and suction tubing. Depending on the procedure, be sure
to have the appropriate Chest Drainage Unit, Nasal Gastric tube, aspirating tip, or wound drain for patient use.
The Instavac® mobile aspirator is now ready to place into service.
OPERATING INSTRUCTIONS
Verify that a clean bacteriostatic exhaust lter, in line suction lter, collection canister, and the necessary tubing
are installed on the Instavac®.
ORAL, NASAL AND TRACHEAL ASPIRATION
1. Place a clean collection canister in the upper bracket, which is located on the backpole assembly of your
Instavac® . Ensure that the tubing is connected from the “VACUUM PORT ASSEMBLY” of the Instavac®
to the “vacuum port” of the collection canister and from the “patient port” of the collection canister to the
3. On Intermittent Model (756000) switch the unit to “CONSTANT” suction using the “MODE SELECTION”
switch. Plug the vacuum port located at the top of the backpole and adjust the vacuum to the desired
vacuum level by using the “VACUUM REGULATOR” Knob.
4. Connect the tubing to the vacuum port located at the top of the backpole and proceed with the suction
procedure.

8. Connect the tubing to the vacuum port located at the top of the backpole and proceed with the suction
procedure.
PLEURAL DRAINAGE
®
Instavac
can be utilized with any “Disposable Chest Drainage Unit” available on the market. Some chest
drainage units come with a built-in ow adjustment valve and some do not. The Ohio Medical Needle Valve
Assembly is available for those units that do not offer this built-in ow adjustment valve.
Follow all manufacturer’s directions on the Chest Drainage Unit for its setup and use.
Chest Drainage Units WITHOUT Built-in Flow Adjustment Valves.
Place the Chest Drainage Unit in the “optional” Ohio Medical Chest Drainage Unit Bracket. Ensure that the
tubing is connected from the “VACUUM PORT ASSEMBLY” of the Instavac® to the Ohio Medical Needle
Valve Assembly which is mounted in the collection canister bracket of the backpole. Connect the tubing from
the Needle Valve Assembly to the vacuum port tubing of the Chest Drainage Unit.
OR
Chest Drainage units WITH Built-in Flow Adjustment Valves.
Place the Chest Drainage Unit in the “optional” Ohio Medical Chest Drainage Unit Bracket. Ensure that tubing
is connected from the “VACUUM PORT ASSEMBLY” of the Instavac® to the vacuum port tubing of the Chest
2. On Intermittent Model (756000) switch the unit to “CONSTANT” suction using the “MODE SELECTION”
®
switch. Plug the vacuum port located at the top of the backpole and adjust the Instavac
to a low vacuum
setting by using the “VACUUM REGULATOR” knob.
NOTE: the Chest Drainage Unit regulates the vacuum level provided to the chest cavity. Setting the Instavac
®
to a low vacuum level ensures that you are producing sufcient vacuum to properly operate the chest drainage
unit.
3. Connect the tubing to the vacuum port located at the top of the backpole and proceed with the suction
procedure.
8. REPROCESSING AND CLEANING INSTRUCTIONS
1. After EACH suctioning procedure, discard ALL contaminated parts, in accordance with local ordinances.
These components may include the collection canister, disposable chest drainage unit, in-line lter, exhaust
lter, and all suction tubing.
2. Wipe the surface of the unit with a mild antiseptic and a clean soft cloth.
®
3. Place a new collection canister, suction tubing, and lters with the Instavac
.
4. Check the air inlet lter at the back of the unit to make sure that it is clear of any dirt. Thoroughly rinse in
water. After the lter is completely dry, reinstall the lter.
5. If cleaning is necessary, vacuum the lter. If dirt is excessive, wash in a mild antiseptic and inspect the
overow trap assembly for any evidence of an accidental overow. If an overow has occurred, use the
following guidelines.
OVERFLOW - Aspirant has contaminated the overow trap assembly. Replace and/or clean parts
according to the procedures described in OVERFLOW CLEANING PROCEDURE below.
SEVERE OVERFLOW - Aspirant has contaminated the overow trap assembly and the vacuum port
tubing. Replace and/or clean external parts according to procedure described in OVERFLOW CLEANING
PROCEDURE below. In addition, open the unit to assess the extent of the internal over ow.
OVERFLOW CLEANING PROCEDURENOTE: THESE PROCEDURES ARE ONLY REQUIRED WHEN AN OVERFLOW
HAS OCCURRED.
1. Discard all external contaminated tubing in accordance with local ordinances.
2. Clean the overow trap assembly by unscrewing the cap and disassembling the various components. Wash
all parts with a mild antiseptic. Dry, reassemble the overow trap assembly. Verify that the oat is in the
down position and the cap seals tightly on the glass jar.
3. Replace all discarded tubing.
4. If the vacuum port tubing was contaminated, open the unit and inspect the following parts for contamination
(see MAINTENANCE section below for opening the unit):
All Internal Tubing: If contaminated, replace.
Regulator Assembly: If contaminated, clean according to procedure on page 9.
Solenoid Manifold Assembly: If contaminated, clean according to procedure on page 10.
Pump Assembly: If contaminated, clean according to procedure on page 11.

NOTE: Before reassembling the pump, make certain that all components are completely dry. Rust may form if
5. Replace the vanes, wear plate, shim, and cover plate.
6. Replace and equally tighten the three (3) pump head screws.
7. Reinstall the pump assembly.
10. PERFORMANCE TEST AND ADJUSTMENT
Due to circumstances such as an overow, maintenance and preventive maintenance, readjusting these levels
may be necessary. It is recommended that you verify the specications and the performance of the Instavac
whenever any type of maintenance or an overow has occurred.
To verify pump and regulator operation:
1. Plug the power cord into an electrical outlet. Turn the unit ON (I) and listen to make sure that the pump
starts.
®
2. On Intermittent Model (756000) switch the unit to “CONSTANT” with the “MODE SELECTION” switch.
Plug the vacuum port (located at the top of the backpole) and adjust the vacuum level by turning the vacuum
regulator knob. While turning the regulator knob, verify that the vacuum gauge reects a change in vacuum
level. Verify that you feel vacuum at your nger tip.
1. With a ow testing device attached to the vacuum outlet, turn the unit ON (I). Switch to“INTERMITTENT”
suction and adjust the vacuum regulator knob (located on the control panel) to full vacuum.
2. With a 1/16” Allen wrench, loosen the set screw. Turn the ow adjustment valve until the ow specication
(page 13) is reached. Tighten the set screw.
